Devices, methods, and graphical user interfaces for messaging

TECHNICAL FIELD

0001This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that send and receive messages, such as instant messages.

BACKGROUND

0002The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touchpads and touch-screen displays. Such devices are often used to send messages, such as instant messages, between users using messaging applications.

0003But current messaging applications have numerous drawbacks and limitations. For example, they are limited in their ability to easily: acknowledge messages; edit previously sent messages; express what a user is trying to communicate; display private messages; synchronize viewing of content between users; incorporate handwritten inputs; quickly locate content in a message transcript; integrate a camera; integrate search and sharing; integrate interactive applications; integrate stickers; make payments; interact with avatars; make suggestions; navigate among interactive applications; manage interactive applications; translate foreign language text; combine messages into a group; and flag messages.

SUMMARY

0004Accordingly, there is a need for electronic devices with improved methods and interfaces for messaging. Such methods and interfaces optionally complement or replace conventional methods for messaging. Such methods and interfaces change the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

In some embodiments, the conversation transcript includes a representation of a media item that is displayed at a chronological position within the conversation transcript, and the messaging session is configured to allow synchronized viewing of the media item by the user at the first electronic device and the at least one other user at a second electronic device that is distinct from the first electronic device. The processing unit is also configured to: receive a first request for synchronized viewing of the media item within the messaging user interface and, in response to receiving the first request, initiate playing of content corresponding to the media item while the representation of the media item is displayed at the chronological position within the conversation transcript. After initiating playing of the content corresponding to the media item, the processing unit is configured to: display the playing content corresponding to the media item at a fixed position within the messaging user interface that is different than the chronological position. While displaying the playing content corresponding to the media item at the fixed position, the processing unit is configured to: display messages exchanged between the user and the at least one other user below the playing content corresponding to the media item and detect an end of the content corresponding to the media item. In response to detecting the end of the content corresponding to the media item, the processing unit is configured to: cease to display the content corresponding to the media item at the fixed position.

For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. Furthermore, allowing users to simply rotate their devices in order to begin entering handwritten inputs, auto-replacing typed inputs, and creating keyboards with handwritten characters as keys all contribute to enhancing the operability of the devices and making the user-device interfaces (e.g., in the messaging application) more efficient (e.g., by allowing users to easily customize their message content with handwritten inputs) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. For example, the user need not leave the messaging application, open and use a different application to input or locate handwritten inputs, and then return to use those inputs in the messaging application. Instead, the user simple provides and/or selects custom handwritten inputs directly within the messaging application.

For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise.

0129The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms "includes," "including," "comprises," and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

0130As used herein, the term "if' is, optionally, construed to mean "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [a stated condition or event] is detected" is, optionally, construed to mean "upon determining" or "in response to determining" or "upon detecting [the stated condition or event]" or "in response to detecting [the stated condition or event]," depending on the context.

0131Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Example embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad).

0132In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

0133In addition to a messaging application, the device typically supports a variety of other applications, such as one or more of the following: a note taking application, a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

0134The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

0135Attention is now directed toward embodiments of portable devices with touch-sensitive displays. <figref idref="f0001">Figure 1A</figref> is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display system 112 is sometimes called a "touch screen" for convenience, and is sometimes simply called a touch-sensitive display. Device 100 includes memory 102 (which optionally includes one or more computer readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensities of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

0136As used in the specification and claims, the term "tactile output" refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a "down click" or "up click" of a physical actuator button. In some cases, a user will feel a tactile sensation such as an "down click" or "up click" even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as "roughness" of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an "up click," a "down click," "roughness"), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. Using tactile outputs to provide haptic feedback to a user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

0137It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in <figref idref="f0001">Figure 1A</figref> are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

0138Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU(s) 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.

0139Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU(s) 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

0140In some embodiments, peripherals interface 118, CPU(s) 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

0141RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.1 In), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

0142Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, <figref idref="f0003">Figure 2</figref>). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

0143I/O subsystem 106 couples input/output peripherals on device 100, such as touch-sensitive display system 112 and other input or control devices 116, with peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input or control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g., 208, <figref idref="f0003">Figure 2</figref>) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, <figref idref="f0003">Figure 2</figref>).

0144Touch-sensitive display system 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch-sensitive display system 112. Touch-sensitive display system 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed "graphics"). In some embodiments, some or all of the visual output corresponds to user interface objects. As used herein, the term "affordance" refers to a user-interactive graphical user interface object (e.g., a graphical user interface object that is configured to respond to inputs directed toward the graphical user interface object). Examples of user-interactive graphical user interface objects include, without limitation, a button, slider, icon, selectable menu item, switch, hyperlink, or other user interface control.

0145Touch-sensitive display system 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch-sensitive display system 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch-sensitive display system 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system 112. In an example embodiment, a point of contact between touch-sensitive display system 112 and the user corresponds to a finger of the user or a stylus.

0146Touch-sensitive display system 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system 112. In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, California.

0147Touch-sensitive display system 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

0148In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system 112 or an extension of the touch-sensitive surface formed by the touch screen.

Optical sensor(s) 164 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 164 receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor(s) 164 optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch-sensitive display system 112 on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.).

0151Device 100 optionally also includes one or more contact intensity sensors 165. <figref idref="f0001">Figure 1A</figref> shows a contact intensity sensor coupled with intensity sensor controller 159 in I/O subsystem 106.

Contact intensity sensor(s) 165 receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112).

0152Device 100 optionally also includes one or more proximity sensors 166. <figref idref="f0001">Figure 1A</figref> shows proximity sensor 166 coupled with peripherals interface 118. Alternately, proximity sensor 166 is coupled with input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch-sensitive display system 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

0153Device 100 optionally also includes one or more tactile output generators 167. <figref idref="f0001">Figure 1A</figref> shows a tactile output generator coupled with haptic feedback controller 161 in I/O subsystem 106. Tactile output generator(s) 167 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s) 167 receive tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch-sensitive display system 112, which is located on the front of device 100.

0154Device 100 optionally also includes one or more accelerometers 168. <figref idref="f0001">Figure 1A</figref> shows accelerometer 168 coupled with peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled with an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

Furthermore, in some embodiments, memory 102 stores device/global internal state 157, as shown in <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system 112; sensor state, including information obtained from the device's various sensors and other input or control devices 116; and location and/or positional information concerning the device's location and/or attitude.

0156Operating system 126 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

0157Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California.

0158Contact/motion module 130 optionally detects contact with touch-sensitive display system 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., "multitouch"/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

0159Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

0160In some embodiments, detecting a finger tap gesture depends on the length of time between detecting the finger-down event and the finger-up event, but is independent of the intensity of the finger contact between detecting the finger-down event and the finger-up event. In some embodiments, a tap gesture is detected in accordance with a determination that the length of time between the finger-down event and the finger-up event is less than a predetermined value (e.g., less than 0.1, 0.2, 0.3, 0.4 or 0.5 seconds), independent of whether the intensity of the finger contact during the tap meets a given intensity threshold (greater than a nominal contact-detection intensity threshold), such as a light press or deep press intensity threshold. Thus, a finger tap gesture can satisfy particular input criteria that do not require that the characteristic intensity of a contact satisfy a given intensity threshold in order for the particular input criteria to be met. For clarity, the finger contact in a tap gesture typically needs to satisfy a nominal contact-detection intensity threshold, below which the contact is not detected, in order for the finger-down event to be detected. A similar analysis applies to detecting a tap gesture by a stylus or other contact. In cases where the device is capable of detecting a finger or stylus contact hovering over a touch sensitive surface, the nominal contact-detection intensity threshold optionally does not correspond to physical contact between the finger or stylus and the touch sensitive surface.

0161The same concepts apply in an analogous manner to other types of gestures. For example, a swipe gesture, a pinch gesture, a depinch gesture, and/or a long press gesture are optionally detected based on the satisfaction of criteria that are either independent of intensities of contacts included in the gesture, or do not require that contact(s) that perform the gesture reach intensity thresholds in order to be recognized. For example., a swipe gesture is detected based on an amount of movement of one or more contacts; a pinch gesture is detected based on movement of two or more contacts towards each other; a depinch gesture is detected based on movement of two or more contacts away from each other; and a long press gesture is detected based on a duration of the contact on the touch-sensitive surface with less than a threshold amount of movement. As such, the statement that particular gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met means that the particular gesture recognition criteria are capable of being satisfied if the contact(s) in the gesture do not reach the respective intensity threshold, and are also capable of being satisfied in circumstances where one or more of the contacts in the gesture do reach or exceed the respective intensity threshold. In some embodiments, a tap gesture is detected based on a determination that the finger-down and finger-up event are detected within a predefined time period, without regard to whether the contact is above or below the respective intensity threshold during the predefined time period, and a swipe gesture is detected based on a determination that the contact movement is greater than a predefined magnitude, even if the contact is above the respective intensity threshold at the end of the contact movement. Even in implementations where detection of a gesture is influenced by the intensities of contacts performing the gesture (e.g., the device detects a long press more quickly when the intensity of the contact is above an intensity threshold or delays detection of a tap input when the intensity of the contact is higher), the detection of those gestures does not require that the contacts reach a particular intensity threshold so long as the criteria for recognizing the gesture can be met in circumstances where the contact does not reach the particular intensity threshold (e.g., even if the amount of time that it takes to recognize the gesture changes).

0162Contact intensity thresholds, duration thresholds, and movement thresholds are, in some circumstances, combined in a variety of different combinations in order to create heuristics for distinguishing two or more different gestures directed to the same input element or region so that multiple different interactions with the same input element are enabled to provide a richer set of user interactions and responses. The statement that a particular set of gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met does not preclude the concurrent evaluation of other intensity-dependent gesture recognition criteria to identify other gestures that do have a criteria that is met when a gesture includes a contact with an intensity above the respective intensity threshold. For example, in some circumstances, first gesture recognition criteria for a first gesture - which do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met - are in competition with second gesture recognition criteria for a second gesture - which are dependent on the contact(s) reaching the respective intensity threshold. In such competitions, the gesture is, optionally, not recognized as meeting the first gesture recognition criteria for the first gesture if the second gesture recognition criteria for the second gesture are met first. For example, if a contact reaches the respective intensity threshold before the contact moves by a predefined amount of movement, a deep press gesture is detected rather than a swipe gesture. Conversely, if the contact moves by the predefined amount of movement before the contact reaches the respective intensity threshold, a swipe gesture is detected rather than a deep press gesture. Even in such circumstances, the first gesture recognition criteria for the first gesture still do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met because if the contact stayed below the respective intensity threshold until an end of the gesture (e.g., a swipe gesture with a contact that does not increase to an intensity above the respective intensity threshold), the gesture would have been recognized by the first gesture recognition criteria as a swipe gesture. As such, particular gesture recognition criteria that do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met will (A) in some circumstances ignore the intensity of the contact with respect to the intensity threshold (e.g. for a tap gesture) and/or (B) in some circumstances still be dependent on the intensity of the contact with respect to the intensity threshold in the sense that the particular gesture recognition criteria (e.g., for a long press gesture) will fail if a competing set of intensity-dependent gesture recognition criteria (e.g., for a deep press gesture) recognize an input as corresponding to an intensity-dependent gesture before the particular gesture recognition criteria recognize a gesture corresponding to the input (e.g., for a long press gesture that is competing with a deep press gesture for recognition).

0186In conjunction with touch-sensitive display system 112, display system controller 156, contact module 130, graphics module 132, audio circuitry 110, speaker 111, RF circuitry 108, text input module 134, e-mail client module 140, and browser module 147, online video module 155 includes executable instructions that allow the user to access, browse, receive (e.g., by streaming and/or download), play back (e.g., on the touch screen 112, or on an external display connected wirelessly or via external port 124), send an e-mail with a link to a particular online video, and otherwise manage online videos in one or more file formats, such as H.264. In some embodiments, instant messaging module 141, rather than e-mail client module 140, is used to send a link to a particular online video.

0187Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

0188In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

0189The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a "menu button" is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

0190<figref idref="f0002">Figure 1B</figref> is a block diagram illustrating example components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in <figref idref="f0001">Figures 1A</figref>) or 370 (<figref idref="f0004">Figure 3</figref>) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 136, 137-155, 380-390).

0191Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display system 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

0192In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

0193Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display system 112 or a touch-sensitive surface.

0194In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

0195In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

0196Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

0197Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

0198Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

0199Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

0200Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

0201In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

0202In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

0203A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

0204Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

0205Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display system 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

0206In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system 112, when a touch is detected on touch-sensitive display system 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

0207In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

0208When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

0209In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

0210In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

0211In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

0212In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

0213In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

0214It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

0215<figref idref="f0003">Figure 2</figref> illustrates a portable multifunction device 100 having a touch screen (e.g., touch-sensitive display system 112, <figref idref="f0001">Figure 1A</figref>) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

0216Device 100 optionally also includes one or more physical buttons, such as "home" or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display.

0217In some embodiments, device 100 includes the touch-screen display, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensities of contacts on touch-sensitive display system 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

0218<figref idref="f0004">Figure 3</figref> is a block diagram of an example multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch-screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to <figref idref="f0001">Figure 1A</figref>), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to <figref idref="f0001">Figure 1A</figref>). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (<figref idref="f0001">Figure 1A</figref>), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (<figref idref="f0001">Figure 1A</figref>) optionally does not store these modules.

0219Each of the above identified elements in <figref idref="f0004">Figure 3</figref> are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

0220Attention is now directed towards embodiments of user interfaces ("UI") that are, optionally, implemented on portable multifunction device 100.

0221<figref idref="f0005">Figure 4A</figref> illustrates an example user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof: <ul id="ul0003" list-style="bullet"><li>Signal strength indicator(s) 402 for wireless communication(s), such as cellular and Wi-Fi signals;</li><li>Time 404;</li><li>Bluetooth indicator 405;</li><li>Battery status indicator 406;</li><li>Tray 408 with icons for frequently used applications, such as: <ul id="ul0004" list-style="none"><li>∘ Icon 416 for telephone module 138, labeled "Phone," which optionally includes an indicator 414 of the number of missed calls or voicemail messages;</li><li>∘ Icon 418 for e-mail client module 140, labeled "Mail," which optionally includes an indicator 410 of the number of unread e-mails;</li><li>∘ Icon 420 for browser module 147, labeled "Browser;" and</li><li>∘ Icon 422 for video and music player module 152, also referred to as iPod (trademark of Apple Inc.) module 152, labeled "iPod;" and</li></ul></li><li>Icons for other applications, such as: <ul id="ul0005" list-style="none"><li>∘ Icon 424 for IM module 141, labeled "Messages;"</li><li>∘ Icon 426 for calendar module 148, labeled "Calendar;"</li><li>∘ Icon 428 for image management module 144, labeled "Photos;"</li><li>∘ Icon 430 for camera module 143, labeled "Camera;"</li><li>∘ Icon 432 for online video module 155, labeled "Online Video;"</li><li>∘ Icon 434 for stocks widget 149-2, labeled "Stocks;"</li><li>∘ Icon 436 for map module 154, labeled "Map;"</li><li>∘ Icon 438 for weather widget 149-1, labeled "Weather;"</li><li>∘ Icon 440 for alarm clock widget 149-4, labeled "Clock;"</li><li>∘ Icon 442 for workout support module 142, labeled "Workout Support;"</li><li>∘ Icon 444 for notes module 153, labeled "Notes;" and</li><li>∘ Icon 446 for a settings application or module, which provides access to settings for device 100 and its various applications 136.</li></ul></li></ul>

0222It should be noted that the icon labels illustrated in <figref idref="f0005">Figure 4A</figref> are merely examples. For example, in some embodiments, icon 422 for video and music player module 152 is labeled "Music" or "Music Player." Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

0223<figref idref="f0006">Figure 4B</figref> illustrates an example user interface on a device (e.g., device 300, <figref idref="f0004">Figure 3</figref>) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, <figref idref="f0004">Figure 3</figref>) that is separate from the display 450. Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensities of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

0224<figref idref="f0006">Figure 4B</figref> illustrates an example user interface on a device (e.g., device 300, <figref idref="f0004">Figure 3</figref>) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, <figref idref="f0004">Figure 3</figref>) that is separate from the display 450. Although many of the examples that follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in <figref idref="f0006">FIG. 4B</figref>. In some embodiments, the touch-sensitive surface (e.g., 451 in <figref idref="f0006">Figure 4B</figref>) has a primary axis (e.g., 452 in <figref idref="f0006">Figure 4B</figref>) that corresponds to a primary axis (e.g., 453 in <figref idref="f0006">Figure 4B</figref>) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in <figref idref="f0006">Figure 4B</figref>) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in <figref idref="f0006">Figure 4B</figref>, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in <figref idref="f0006">Figure 4B</figref>) are used by the device to manipulate the user interface on the display (e.g., 450 in <figref idref="f0006">Figure 4B</figref>) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

0225Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

0226As used herein, the term "focus selector" is an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a "focus selector," so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in <figref idref="f0004">Figure 3</figref> or touch-sensitive surface 451 in <figref idref="f0006">Figure 4B</figref>) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in <figref idref="f0001">Figure 1A</figref> or the touch screen in <figref idref="f0005">Figure 4A</figref>) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a "focus selector," so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

0227As used in the specification and claims, the term "intensity" of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact or a stylus contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average or a sum) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be readily accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

0228In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has "clicked" on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse "click" threshold of a trackpad or touch-screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch-screen display hardware. Additionally, in some implementations a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click "intensity" parameter).

0229As used in the specification and claims, the term "characteristic intensity" of a contact is a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

0230In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

0231The user interface figures described herein optionally include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT₀, a light press intensity threshold IT_L, a deep press intensity threshold IT_D (e.g., that is at least initially higher than I_L), and/or one or more other intensity thresholds (e.g., an intensity threshold I_H that is lower than I_L)). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold ITo below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

0232In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some "light press" inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some "deep press" inputs, the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold for a light press, triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental deep press inputs. As another example, for some "deep press" inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental deep press inputs. For other deep press inputs, the response to detection of a deep press input does not depend on time-based criteria.

0233In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Example factors are described in <patcit id="pcit0001" dnum="US399606A"><text>U.S. Patent Application Serial Nos. 14/399,606</text></patcit> and <patcit id="pcit0002" dnum="US14624296B"><text>14/624,296</text></patcit>, which are incorporated by reference herein in their entireties.

0234For example, <figref idref="f0007">Figure 4C</figref> illustrates a dynamic intensity threshold 480 that changes over time based in part on the intensity of touch input 476 over time. Dynamic intensity threshold 480 is a sum of two components, first component 474 that decays over time after a predefined delay time p1 from when touch input 476 is initially detected, and second component 478 that trails the intensity of touch input 476 over time. The initial high intensity threshold of first component 474 reduces accidental triggering of a "deep press" response, while still allowing an immediate "deep press" response if touch input 476 provides sufficient intensity. Second component 478 reduces unintentional triggering of a "deep press" response by gradual intensity fluctuations of in a touch input. In some embodiments, when touch input 476 satisfies dynamic intensity threshold 480 (e.g., at point 481 in <figref idref="f0007">Figure 4C</figref>), the "deep press" response is triggered.

0235<figref idref="f0007">Figure 4D</figref> illustrates another dynamic intensity threshold 486 (e.g., intensity threshold I_D). <figref idref="f0007">Figure 4D</figref> also illustrates two other intensity thresholds: a first intensity threshold I_H and a second intensity threshold I_L. In <figref idref="f0007">Figure 4D</figref>, although touch input 484 satisfies the first intensity threshold I_H and the second intensity threshold I_L prior to time p2, no response is provided until delay time p2 has elapsed at time 482. Also in <figref idref="f0007">Figure 4D</figref>, dynamic intensity threshold 486 decays over time, with the decay starting at time 488 after a predefined delay time p1 has elapsed from time 482 (when the response associated with the second intensity threshold I_L was triggered). This type of dynamic intensity threshold reduces accidental triggering of a response associated with the dynamic intensity threshold I_D immediately after, or concurrently with, triggering a response associated with a lower intensity threshold, such as the first intensity threshold I_H or the second intensity threshold I_L.

0236<figref idref="f0008">Figure 4E</figref> illustrate yet another dynamic intensity threshold 492 (e.g., intensity threshold I_D). In <figref idref="f0008">Figure 4E</figref>, a response associated with the intensity threshold I_L is triggered after the delay time p2 has elapsed from when touch input 490 is initially detected. Concurrently, dynamic intensity threshold 492 decays after the predefined delay time p1 has elapsed from when touch input 490 is initially detected. So a decrease in intensity of touch input 490 after triggering the response associated with the intensity threshold I_L, followed by an increase in the intensity of touch input 490, without releasing touch input 490, can trigger a response associated with the intensity threshold I_D (e.g., at time 494) even when the intensity of touch input 490 is below another intensity threshold, for example, the intensity threshold I_L.

0237An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold IT_L to an intensity between the light press intensity threshold IT_L and the deep press intensity threshold IT_D is sometimes referred to as a "light press" input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold IT_D to an intensity above the deep press intensity threshold IT_D is sometimes referred to as a "deep press" input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold IT₀ to an intensity between the contact-detection intensity threshold IT₀ and the light press intensity threshold IT_L is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold IT₀ to an intensity below the contact-detection intensity threshold IT₀ is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT₀ is zero. In some embodiments, IT₀ is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

0238In some embodiments, described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., the respective operation is performed on a "down stroke" of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., the respective operation is performed on an "up stroke" of the respective press input).

0239In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed "jitter," where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on an "up stroke" of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

0240For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. As described above, in some embodiments, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a first intensity threshold being met and a second intensity threshold being met).

USER INTERFACES AND ASSOCIATED PROCESSES

0241Attention is now directed towards embodiments of user interfaces ("UI") and associated processes that may be implemented on an electronic device, such as portable multifunction device 100 or device 300, with a display, a touch-sensitive surface, and (optionally) one or more sensors to detect intensities of contacts with the touch-sensitive surface.

0242These user interfaces and associated processes provide new, improved ways to: <ul id="ul0006" list-style="bullet"><li>acknowledge messages;</li><li>edit previously sent messages;</li><li>display an edit history for a previously sent message;</li><li>apply impact effect options to a message (e.g., to express what a user is trying to communicate);</li><li>display private messages using "invisible ink";</li><li>display enhanced message interface content (e.g., "full screen moments");</li><li>display content (e.g., "magic moments") that corresponds to particular combinations of content in two separate messages;</li><li>build message bubbles;</li><li>suggest emojis</li><li>synchronize viewing of content between users;</li><li>incorporate handwritten inputs;</li><li>selectively scrunch content in a message transcript;</li><li>integrate a camera;</li><li>integrate search and sharing;</li><li>integrate interactive applications;</li><li>integrate stickers;</li><li>make payments;</li><li>interact with avatars; and</li><li>make suggestions.</li></ul>

0243<figref idref="f0009 f0019">Figures 5A-5K</figref> illustrate exemplary user interfaces for displaying message transcripts and message acknowledgments in accordance with some embodiments. In particular, <figref idref="f0009">Figure 5A</figref> illustrates a messaging user interface 5002 of a messaging user interface (e.g., for a messaging application), displayed on the display of an electronic device, sometimes called the first electronic device to help distinguish it from other electronic devices in communication with the first electronic device. The first electronic device also includes a touch-sensitive surface and one or more sensors, such as in a touch-screen display or trackpad, configured to detect intensities of contacts on the touch-sensitive surface.

0244The messaging user interface 5002, as shown in <figref idref="f0009">Figure 5A</figref>, includes a conversation transcript 5004 of a messaging session between a user (e.g., Genevive) of the electronic device and at least one other user (e.g., Isaac) of another electronic device). The conversation transcript 5004 in this example includes multiple messages, each in a respective message region 5008. A first input with a first contact 5010 at the location on the touch-sensitive surface corresponding to a first message 5006. In response to detecting the first input 5010, the electronic device displays an acknowledgement selection affordance 5012, <figref idref="f0010">Figure 5B</figref>, at a location in the messaging interface that corresponds to the first message region. In this example, the acknowledgement selection affordance displays a plurality of acknowledgement options: 5014-1 (heart), 5014-2 (thumbs up), 5014-3 (thumbs down), 5014-4 ("HA"), 5014-5 ("!!") and 5014-6 ("?"). Other embodiments may include fewer, additional or different acknowledgment options. The electronic device responds to receiving a second input 5106 by a second contact (e.g., a tap gesture, light press gesture, deep press gesture, or lift off) on a respective acknowledgment option (or a hit region corresponding to the respective acknowledgment option), such as option 5014-2 (thumbs up), to select respective acknowledgment option and apply it to the first message 5006 or first message region 5008-1, as shown in <figref idref="f0011">Figure 5C</figref>. The selected acknowledgment option, in this example option 5014-2, is displayed in a respective acknowledgement region 5018. As shown in <figref idref="f0016">Figure 5H</figref>, the electronic device(s) of other user(s) (in this example, Isaac) participating in the messaging session (sometimes called a conversation) display the same selected acknowledgment option proximate for the first message region.

0245To edit the selected acknowledgement option, the user make a third input by a third contact 5022, as shown in <figref idref="f0011">Figure 5C</figref>. Upon detecting the third input by the third contact, the electronic device displays an acknowledgement editing interface 5024, as shown in <figref idref="f0012">Figure 5D</figref>. Optionally, the acknowledgement editing interface is displayed on top of and/or in place of the conversation transcript. Optionally the currently selected acknowledgment option, in this example option 5014-2, is visually distinguished from the other available acknowledgement options in the acknowledgement editing interface 5024, as shown in <figref idref="f0012">Figure 5D</figref>.

0246<figref idref="f0013">Figure 5E</figref> shows an input, contact 5026, selecting a different, second acknowledgement option 5014-1, and <figref idref="f0014">Figure 5F</figref> shows a message region in a conversation transcript with the edited acknowledgment (i.e., with second acknowledgement option 5014-1 displayed instead of first acknowledgement option 5014-2).

0247In some embodiments, while the user of the first electronic device is using the acknowledgement editing interface 5024 to edit a previously selected acknowledgment option for the first message region, the electronic device of another user in the messaging session displays an acknowledgement-preparation indicator 5020, as shown in <figref idref="f0015">Figure 5G</figref>, proximate (e.g., near, adjacent or partially overlapping) the first message region in the conversation transcript 5004 displayed by that electronic device.

0248Different users in the same messaging session may select different acknowledgment options for the same message or message region. In some embodiments, as shown in <figref idref="f0017">Figure 5I</figref>, the electronic device displays, in the conversation transcript, an indicia 5036, that users in the messaging session have selected a plurality of acknowledgements options for the second message region. In the example shown in <figref idref="f0017">Figure 5I</figref>, indicia 5036 is a stack of overlapping acknowledgement option icons, but could alternatively be a plurality of individual acknowledgement option icons. As shown in <figref idref="f0017">Figure 5I</figref>, indicia 5036 is optionally adjacent to and/or partially overlapping the second message region 5008-02.

0249<figref idref="f0018">Figure 5J</figref> shows an example of a user interface that includes a tally for each type of acknowledgement option selected by the users in the messaging session. For example, as shown in <figref idref="f0018">Figure 5J</figref>, the user interface includes tallies 5040-1, 5040-2, 5040-3 for three distinct acknowledgement options selected by users in the messaging session. In some embodiments, the user messaging interface shown in <figref idref="f0018">Figure 5J</figref> is displayed by the electronic device in response to detecting an input by a contact (e.g., contact 5034, <figref idref="f0582">Figure 51</figref>) at a location on the touch-sensitive surface that corresponds to a location of the message region having indicia 5036, which indicates that multiple user in the messaging session have selected acknowledgement options for the same message (or corresponding message region).

0250By selecting one of the tallies 5040, a user can see the users who selected any particular acknowledgement option. The electronic device, in response to an input by a contact (e.g., contact 5041, as shown in <figref idref="f0018">Figure 5J</figref>) at a location on the touch-sensitive surface that corresponds to the tally 5040 for a particular acknowledgement option for a respective message region, displays icons 5042 (e.g., avatars) that represent users that selected the particular acknowledgement option for the respective message region, as shown in <figref idref="f0019">Figure 5K</figref>.

0251<figref idref="f0020 f0028">Figures 5L-5T</figref> illustrate exemplary user interfaces for editing previously sent messages while displaying a message transcript. <figref idref="f0020">Figure 5L</figref> shows a messaging user interface 5002 of a messaging application on the display of an electronic device. The messaging user interface 5002 includes a conversation transcript 5004 of a messaging session between a user of the electronic device and at least one other user, and a first message region 5044 that includes a first message 5046-1 that was sent from the electronic device of the user to the at least one other user in the messaging session.

0252The first message 5046-1 can be edited, despite the fact that it has already been sent. To initiate the editing of the first message, the user selects the first message with a predefined touch input 5048 (e.g., a tap gesture, long press gesture, light press gesture, or deep press gesture) on the first message or the message region for the first message. In some embodiments, the electronic device, in response to detecting the input 5048, displays a menu interface, such as the one shown in <figref idref="f0021">Figure 5M</figref>. Alternatively, the electronic device, in response to detecting the input 5048, displays a message editing interface 5022, as shown in <figref idref="f0022">Figure 5N</figref>. In some embodiments, a first input gesture (e.g., a tap gesture) on the first message is used to transition to the menu interface (e.g., as shown in <figref idref="f0021">Figure 5M</figref>), while a second input gesture (e.g., a deep press) is used to transition to the message editing interface 5052, <figref idref="f0022">Figure 5N</figref>. From the menu interface, as shown in <figref idref="f0021">Figure 5M</figref>, a user can transition the messaging application to the message editing interface 5022, shown in <figref idref="f0022">Figure 5N</figref>, by a touch input 5050 (<figref idref="f0021">Figure 5M</figref>) that selects an edit option in the menu interface.

0253The message editing interface 5052, <figref idref="f0022">Figure 5N</figref>, for editing a respective message, such as first message 5046-1, includes a keyboard 5054, and an update affordance 5056. While displaying the message editing interface 5052 for the respective message, the electronic device detects one or more inputs, such as input 5057 shown in <figref idref="f0022">Figure 5N</figref>, that revise the respective message, displays a revised version of the message, and detects an input that activates the update affordance (e.g., for sending the updated message to the one or more other electronic devices of the one or more other participants in the messaging session.

0254<figref idref="f0023">Figure 5O</figref> shows the conversation transcript 5004 after message 5046 has been updated. Because the conversation transcript 5004 includes an edited message, the edited message includes one or more indications 5058 that a particular message was revised after the original version of the message was sent to the other participant(s) in the messaging session. In <figref idref="f0023">Figure 5O</figref>, there are two such indications of revision: indication 5058-1 is a shadow region behind the message region; indication 5058-2 is text (e.g., "Edited") displayed below the message region that contains the revised version of the message.

0255An edited or revised message can be edited yet again. The electronic device, in response to an input (e.g., input 5060, <figref idref="f0023">Figure 5O</figref>) that corresponds to a request to edit the revised version 5046-2) of a message, displays a message editing interface for the revised version of the message, as shown in <figref idref="f0026">Figure 5R</figref>. The message editing interface, as shown in <figref idref="f0026">Figure 5R</figref>, includes the message 5046-2 to be edited, a keyboard, and an update affordance (which is optionally not shown until at least one revision has been made to the message).

0256A participant in the messaging session can request to see all version, or two or more versions, of an edited message. For example, in response to a predefined input 5060, <figref idref="f0023">Figure 5O</figref>, on an edited message, the electronic device displays the user interface shown in <figref idref="f0024">Figure 5P</figref>, in which display of the conversation transcript is suppressed except for the revised version of the first message 5046-2, and a menu 5062 or list of editing options. In this example, the displayed menu 5062 includes a copy affordance 5064 (for copying the message selected by input 5060), a show edits affordance 5066 (for showing edits to the message selected by input 5060), a delete affordance 5068 (for deleting the message selected by input 5060, or alternatively for undoing all edits made to the message selected by input 5060), and a display more options affordance 5070. In the example shown in <figref idref="f0024">Figure 5P</figref>, input 5072 (e.g., a tap gesture) is detected at the location on the touch-sensitive surface that corresponds to the location of the "show edits" affordance 5066, which when activated, displays a user interface 5074 (<figref idref="f0025">Figure 5Q</figref>) that includes current version 5046-1 of the first message as well as a prior version 5046-2, as shown in <figref idref="f0025">Figure 5Q</figref>. A further input, 5076 or 5078, in the user interface of <figref idref="f0025">Figure 5Q</figref>, selects a version of the message to edit. For example, the selected version is highlighted, and then a touch input on Edit (5080) would initiate editing of the selected version of the message. Alternatively, a touch input on Done (5082) terminates the editing of the selected version of the message.

0257An alternative to the edit menu interface shown in <figref idref="f0024">Figure 5P</figref> is the edit menu interface shown in <figref idref="f0027">Figure 5S</figref>, which includes the selected message (selected in response to input 5060, <figref idref="f0023">Figure 5O</figref>), and a menu that includes an affordance (e.g., a "show edits" option, 5086), which when activated results in display of the user interface shown in <figref idref="f0028">Figure 5T</figref>, which includes the current version 5046-2 of the selected message and one or more prior versions of the selected message (e.g., version 5046-1).

0258<figref idref="f0029 f0066">Figures 5U-5BF</figref> illustrate exemplary user interfaces for applying an impact effect option to a message input or message region. <figref idref="f0029">Figure 5U</figref> illustrates a messaging user interface 5002 having a conversation transcript 5004 of a messaging session between a user (Wendy, in this example) of the electronic device and at least one other user (e.g., Max, in this example, a user of another electronic device), and a message-input area 5100 that includes first message input 5102 (e.g., text, stickers, images, and/or other graphics entered by a user of the electronic device in the message-input area, but not yet sent to the at least one other user in the messaging session). In <figref idref="f0029">Figure 5U</figref>, first message input 5102 has not yet been sent.

0259In some embodiments, to trigger the activation of an impact selection interface 5110, <figref idref="f0035">Figure 5AA</figref>, first input 5102, by a first contact at a location on the touch-sensitive surface that corresponds to a location in the message-input area 5100, includes a particular gesture (e.g., a swipe gesture) received at the message-input area 5100. In this example, the message-input area includes an impact selection affordance 5104 and the location of the contact 5106 of the first input corresponds to the impact selection affordance. In some embodiments, impact selection affordance 5104 is a multipurpose affordance, and a second gesture (e.g., a tap) on the same affordance 5104 is used to send the message 5102 in message input area 5100. The electronic device, upon detecting an input that includes the second gesture on affordance 5104, sends message 5102 and transitions to the user interface shown in <figref idref="f0030">Figure 5V</figref>. Similarly, after message 5102 is sent, the electronic device of the other user receives that message and shows the user interface shown in <figref idref="f0031">Figure 5W</figref>.

0260In some alternative embodiments, illustrated in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>, a deep press input 5108-1, 5108-2, 5108-3, as shown in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>, when detected by the electronic device, causes the messaging application to display an impact selection interface 5110, <figref idref="f0035">Figure 5AA</figref>, that includes a plurality of impact effect options (e.g., impact effect options 5112-1 through 5112-4. The increasing intensity of the deep press input is represented by the intensity diagrams in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>. Further, the deep press input 5108-1, 5108-2, 5108-3, on impact selection affordance 5104, as shown in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>, followed by a drag to the first impact effect option (e.g., input 5108-4 on impact effect option 5112-1, <figref idref="f0035">Figure 5AA</figref>) and then pausing while over the affordance for a respective impact effect option 5112, selects that impact effect option.

0261The impact selection interface 5110, <figref idref="f0035">Figure 5AA</figref>, includes a "bubble" affordance 5114 for displaying a selecting message region impact effect options, and a "screen" affordance 5116 for selecting full screen impact effect options.

0262In some embodiments, the impact selection interface 5110, shows an animated preview of the currently selected impact effect option. For example, the sequence of <figref idref="f0036 f0038">Figures 5AB-5AD</figref> show an animated preview of the "loud" impact effect option, which is a message region impact effect option, being applied to first message input ("Congratulations!") in response to an input 5108-5 at a location on the touch-sensitive surface that corresponds to a location of the "loud" impact effect option. In this example, the preview of the "loud" impact effect option shows the font size of the message and the size of a message region at first increasing and then decreasing.

0263In another example, the, sequence of <figref idref="f0039 f0041">Figures 5AE-5AG</figref> show an animated preview of the "slam" impact effect option, which is a message region impact effect option, being applied to first message input ("Congratulations!") in response to a second input 5108-6 at a location on the touch-sensitive surface that corresponds to a location of the "slam" impact effect option. In this example, the preview of the "slam" impact effect option shows the font size of the message and the size of a message region at first increasing and then decreasing, and at the same time changing the tilt or rotation state of the message region, and optionally changing the shade or color of a background region surrounding the message region. Optionally, the application of a respective impact effect option may change additional characteristics of the message region to which the impact effect option is applied, such as font color, background shade or color within the message region, etc.

0264<figref idref="f0041">Figure 5AG</figref> also shows a third input 5108-7 on a send affordance, at a location corresponding to a user-selected impact effect option, in this case the "slam" option. In response, the electronic device of the user composing the message ceases to display the impact selection interface and displays a message region that contains the first message input in the conversation transcript, and in some embodiments, applies the selected impact effect option to the message region, as shown in <figref idref="f0042">Figure 5AH</figref>, or to the entire conversation transcript, as shown in the <figref idref="f0043">Figure 5AI</figref> (enlarging the message region to which the impact effect option was applied and decreasing the size of one or more other message regions in the conversation transcript), and then transitioning to a final or static display of the conversation transcript that includes the sent message, as shown in <figref idref="f0044">Figure 5AJ</figref>. Similarly, the sent message is displayed at the electronic device of one or more other users in the messaging session, such as Wendy, with the selected impact effect option applied to the either message region of the sent message or the entire conversation transcript, depending on which impact effect option was selected by the sending user, one example of which is shown in the sequence of <figref idref="f0045">Figures 5AK</figref>, <figref idref="f0046">5AL</figref>, <figref idref="f0047">5AM</figref>.

0265The sequence of <figref idref="f0048 f0053">Figures 5AN-5AS</figref> show an example of the "loud" impact effect option applied to a respective sent message ("congrats"). The sequence of <figref idref="f0054 f0057">Figures 5AT-5AW</figref> show an example of the "gentle" impact effect option applied to a respective sent message ("I'm sorry.").

0266In some embodiments, the selected impact effect option is applied to all (or substantially all) of the display screen of an electronic device that sends or receives the message, which includes the message region with the sent message, for a full-screen effect, an example of which is shown by the sequence of user interface images in <figref idref="f0058 f0059 f0060 f0061 f0062 f0063 f0064 f0065 f0066">Figures 5AX through 5BF. Figures 5AX through 5BF</figref> show the progression of the "slam" effect of a first message input ("Hell No!!"), starting with the first message input displayed shown enlarged, rotated and with a dark background (<figref idref="f0058">Figure 5AX</figref>), then displayed even larger and with a somewhat lighter background (<figref idref="f0059">Figure 5AY</figref>), then less enlarged and rotated at a different angle than before (<figref idref="f0060">Figure 5AZ</figref>), then shown with further reduced enlargement and with blurry borders (<figref idref="f0061">Figure 5BA</figref>), then shown with reduced size a different background and a different rotation (<figref idref="f0062">Figure 5BB</figref>) and then with a sequence of different shadows around the message region (<figref idref="f0063">Figures 5BC</figref>, <figref idref="f0064">5BD</figref>, <figref idref="f0065">5BE</figref>) until the first message input is shown at normal (default) size, not rotated, and with a normal (default) background (<figref idref="f0066">Figure 5BF</figref>).

0267<figref idref="f0067 f0087">Figures 5BG-5CA</figref> illustrate exemplary user interfaces for interacting with concealed messages. An impact selection interface 5110, shown in <figref idref="f0067">Figure 5BG</figref>, includes a plurality of impact effect options (e.g., impact effect options 5112-1 through 5112-4, described elsewhere in this document with respect to <figref idref="f0035">Figure 5AA</figref>). In this example, the impact selection interface 5110 also includes a "bubble" affordance 5114 for displaying a selecting message region impact effect options, and a "screen" affordance 5116 for selecting full screen impact effect options.

0268In some embodiments, the displayed impact effect options include an option that conceals the content of a message in the conversation transcript ("invisible ink" option 5112-1, <figref idref="f0035">Figure 5AA</figref>, indicated in <figref idref="f0067">Figure 5BG</figref> by an empty message region). In the example shown in <figref idref="f0067">Figure 5BG</figref>, the invisible ink option includes a send affordance 5118 for sending a message (with user-specified message input) with the respective impact effect option. In the example shown in <figref idref="f0067">Figure 5BG</figref>, impact selection interface 5110 includes a cancel affordance 5120 for canceling the selection of any impact effect options and returning the messaging application to either a prior user interface of the messaging application or a predefined user interface of the messaging application.

0269Once a message (hereinafter called the "concealed message" for ease of reference) has been sent with the invisible ink option, the concealed message is not displayed or is obscured, for example by screen elements 5124 that conceal the message, as shown in <figref idref="f0068">Figure 5BH</figref>, until the user of the electronic device displaying a conversation transcript that includes the concealed message performs a respective gesture, such as sliding a touch input 5128-a, 5128-b, 5128-c over the message region containing the concealed message, as shown in the sequence of <figref idref="f0068 f0069 f0070 f0071 f0072">Figures 5BH through 5BL</figref>, which temporarily reveals a portion of the message corresponding to the position of the touch input 5128-1, 5128-b, 5128-c; or performing a deep press gesture on the message region containing the concealed message, as shown in the sequence of <figref idref="f0073 f0076">Figures 5BM-5BP</figref>, in which the portion of the concealed message that is revealed corresponding to the intensity of the deep press input 5130-a, 5130-b, 5130-c, and optionally also corresponding to the position of the deep press input 5130-a, 5130-b, 5130-c. In these examples, the concealed message is concealed again in response to detecting termination of the input by the contact that caused the concealed message, or portions thereof, to be temporarily revealed.

0270In another example, the sequence of <figref idref="f0077 f0082">Figures 5BQ-5BV</figref>, show a concealed message being gradually revealed, as shown in <figref idref="f0077 f0078 f0079 f0080">Figures 5BQ to 5BT</figref>, and then gradually concealed, as shown in <figref idref="f0080 f0081 f0082">Figures 5BT to 5BV</figref>. In yet another example, the sequence of <figref idref="f0083 f0087">Figures 5BW-5CA</figref>, show a concealed message that contains a picture of photograph being gradually revealed.

0271<figref idref="f0088 f0109">Figures 5CB-5CW</figref> illustrate exemplary user interfaces for triggering enhanced message content and applying an effect to a messaging user interface when a message includes an enhanced message content trigger. More particularly, a respective message in a messaging session can be sent with an enhanced message content trigger, and when an electronic device with a compatible messaging application receives that message with the enhanced message content trigger, the electronic device displays a conversation transcript with the received message and with enhanced message content. In some embodiments, the particular enhanced message content to be displayed is indicated by one or more parameters in the enhanced message content trigger.

0272<figref idref="f0088">Figures 5CB</figref> and <figref idref="f0089">5CC</figref> show an example of a user interface displaying a preview of a full screen impact effect, in this case a full screen impact effect that includes moving or animated balloons 5152-1. As shown in <figref idref="f0088">Figure 5CB</figref>, the user of the electronic device composing the message "Congratulations!" has selected the "screen" affordance 5116, for selecting full screen impact effect options. Similarly, the sequence of <figref idref="f0090 f0092">Figures 5CD-5CF</figref> show an example of a user interface displaying a preview of a full screen impact effect, in this case a full screen impact effect that includes moving or animated confetti 5152-2. In the example shown here, the user navigates through the available full screen impact effects using swipe gestures, such as swipe gesture 5156 shown in <figref idref="f0089">Figure 5CC</figref>, which cause the electronic device to moves from a preview of the balloon full screen impact effect shown in <figref idref="f0089">Figure 5CC</figref> to the confetti full screen impact effect shown in <figref idref="f0090">Figure 5CD</figref>. As shown in <figref idref="f0088">Figures 5CB</figref> and <figref idref="f0089">5CC</figref>, the user interface may include an effect option indicator 5154 (sometimes called page dots) to indicate which full screen effect option is currently selected or is currently being previewed, and also to indicate how many full screen effect options are available and which one of those options in a sequence of the full screen effect options is currently being viewed.

0273<figref idref="f0093">Figure 5CG</figref> is an example of a user interface having a conversation transcript in which none of the messages include an enhanced message content trigger, and thus the messages in the transcript are displayed without displaying enhanced message content corresponding to a trigger.

0274The sequence of <figref idref="f0094 f0101">Figures 5CH-5CO</figref> shows an example of a balloons full screen effect being displayed when a message ("Happy Birthday!!!!!") containing a corresponding enhanced message content trigger is received. Similarly, the sequence of <figref idref="f0102 f0109">Figures 5CP-5CW</figref> shows an example of a fireworks full screen effect being displayed when a message ("Happy New Year!!!") containing a corresponding enhanced message content trigger is received.

0275<figref idref="f0110 f0115">Figures 5CX-5DC</figref> illustrate exemplary user interfaces for detecting and responding to combinable content in separate messages. In <figref idref="f0110">Figure 5CX</figref>, a messaging user interface 5002 includes a conversation transcript 5004 a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device) including a first other user, and a message input area 5100. A received first message 5170 in a first message region 5008 is shown in the conversation transcript 5004. The first message 5170, for example a beer glass, has first combinable content (e.g., an emoticon or an image such as an emoji or a sticker). In <figref idref="f0111">Figure 5CY</figref>, the user of the electronic device inputs a second message 5172 in message input area 5100 of the messaging user interface 5002, and sends the second message 5172 by an input 5174 that selects a send affordance 5118. This results in the display of the messaging user interface shown in <figref idref="f0112">Figure 5CZ</figref>.

0276If the second message 5172 contains second combinable content that forms a predefined combination with the first combinable content in the first message 5170, content 5176, the electronic device displays content that corresponds to the predefined combination, such as an animation of two beer glasses being clicked together (as shown in <figref idref="f0113">Figure 5DA</figref>) and/or display of the word "Cheers!" (as shown in <figref idref="f0113">Figure 5DA</figref>). Similarly, the electronic devices of the one or more other users in the messaging session would display the first message, the second message, and the content that corresponds to the predefined combination. It is noted that the content 5176 that corresponds to the predefined combination may be an animation that is briefly displayed after the second message is sent. Optionally, display of the content that corresponds to the predefined combination is repeated periodically while both the first and second messages with the combinable content are displayed in the conversation transcript 5004, or when other predefined criteria are satisfied (e.g., both the first and second messages with the combinable content are displayed in the conversation transcript 5004 and there has been no new activity in the messaging session for at least N seconds, when N is a predefined value between 1 and 60 seconds).

0277The sequence of <figref idref="f0114">Figures 5DB</figref> and <figref idref="f0115">5DC</figref> show another example of combinable content, in which a first user has sent a first message 5178, "Happy," and the second user inputs a second message 5180, "Birthday!" If the first message and second message both include combinable content corresponding to a predefined combination, then content corresponding to the predefined combination would be displayed in the message transcript of the messaging user interface displayed by either the sender's electronic device, or a recipient's electronic device, or (typically) both. For example, the content that corresponds to the predefined combination in this example might be balloons, similar to those shown in <figref idref="f0094 f0101">Figures 5CH-5CO</figref>.

0278<figref idref="f0116 f0121">Figures 5DD-5DI</figref> illustrate exemplary user interfaces for selecting a message region type or shape, in accordance with some embodiments. <figref idref="f0116">Figure 5DD</figref> shows a messaging user interface 5002 with a message input region 5100 having a first message input 5102 ("Yes!") already entered in the message input region. Messaging user interface 5002 includes a send affordance 5200 in or near message input region 5100, for sending the message that has been input in that region. In addition, <figref idref="f0116">Figure 5DD</figref> shows a input with a contact 5202 on an options affordance 5204.

0279The messaging user interface shown in <figref idref="f0117">Figure 5DE</figref> is displayed in response to input with contact 5202 on options affordance 5204, which includes affordances for a number of message processing options, including a message region type/shape selection affordance 5208, labeled the "bubbles" affordance in <figref idref="f0117">Figure 5DE</figref>. While displaying this messaging user interface, the electronic device receives an input with contact 5206 on the "bubbles" option affordance 5208.

0280The messaging user interface shown in <figref idref="f0118">Figure 5DF</figref> is displayed in response to input with contact 5206 on "bubbles" affordance 5208. <figref idref="f0118">Figure 5DF</figref> also shows a preview message region 5210-1 that includes the first message input 5102, and that has a default, or previously selected, message region type. In these embodiments, the messaging application has a plurality of message region types or options, each having a corresponding shape, and typically having a corresponding font size, and optionally having one or more of: a font color, border color, and/or background color. In the example shown in <figref idref="f0118">Figure 5DF</figref>, the send affordance 5200 is displayed near the preview message region 5210-1 instead of in message input region 5100. To select a different message region type for the first message 5172, or to view other available message region types, the user inputs a swipe gesture 5212. In response to swipe gesture 5212, a scrolling set of message region type icons is scrolled, as shown in the progression from <figref idref="f0118 f0119">Figure 5DF to Figure 5DG</figref>.

0281In the example of the messaging user interface shown in <figref idref="f0119">Figure 5DG</figref>, an input with contact 5214 is received, which causes the electronic device to change the message region type for the message region to be used with message input 5102, as shown in <figref idref="f0120">Figure 5DH</figref>. In <figref idref="f0120">Figure 5DH</figref>, message input 5102 is now shown in a message region 5210-2 having a message region type corresponding to the message region type selected by input with contact 5214 (shown in <figref idref="f0119">Figure 5DG</figref>). The user can continue to select different message region types. For example, in <figref idref="f0121">Figure 5DI</figref>, message input 5102 is now shown in a message region 5210-3 having a message region type corresponding to the message region type selected by input with contact 5216.

0282<figref idref="f0122 f0129">Figures 5DJ-5DQ</figref> illustrate exemplary user interfaces for displaying and selecting automatically suggested emoji while composing a message. In <figref idref="f0122">Figure 5DJ</figref>, a messaging user interface 5002 having a conversation transcript 5004 with an input, but not yet sent, message 5220 in message input region 5100 is shown. In this example, the messaging using interface 5002 includes a send affordance 5200 in or near message input region 5100 for sending the input message.

0283As shown in <figref idref="f0123 f0126">Figures 5DK-5DN</figref>, the electronic device begins to automatically make suggestions of emoji to replace one or more words or terms in the message input region 5100. In the example shown, the electronic device highlights word or terms, in sequence in the message, that are candidates for being replaced by emoji, first highlighting the term "sushi" 5222 in the input message 5220, as shown in <figref idref="f0123">Figures 5DK</figref> and <figref idref="f0124">5DL</figref>, then highlighting the term "wine" 5224 in the input message 5220, as shown in <figref idref="f0125">Figure 5DM</figref>, and then highlighting the term "bowling" 5226 in the input message 5220, as shown in <figref idref="f0126">Figure 5DN</figref>. In response to the user of the electronic device selecting one of the highlight terms (e.g., by an input with a contact on a highlighted term), such as "sushi" 5222 in the input message 5220, that term is replaced by a corresponding emoji 5232 corresponding to that term, as shown in <figref idref="f0127">Figure 5DO</figref>. Similarly, in <figref idref="f0128">Figure 5DP</figref>, the term "wine" in the input message 5220 has been replaced by an emoji 5234 (e.g., a wine glass emoji) corresponding to that term in response to a user selection of the highlighted term "wine" in the input message 5220. In a third example, the term "bowling" in the input message 5220 has been replaced by an emoji 5236 (e.g., a bowling emoji) corresponding to that term in response to a user selection of the highlighted term "bowling" in the input message 5220.

Message Acknowledgements

0284<figref idref="f0130 f0134">Figures 6A-6E</figref> are flow diagrams of a process for applying an acknowledgement to a message region in a conversation transcript, in accordance with some embodiments. More specifically, these methods relate to displaying an acknowledgement selection affordance that includes a plurality of acknowledgement options and applying a selected acknowledgement option to a received message. In some embodiments, an indication of the applied acknowledgement option is transmitted to a remote device (e.g., for display within a conversation transcript of the remote device). The acknowledgement allows a user to quickly communicate a sentiment without having to type multiple words. It saves user time by saving keystrokes and, therefore, creates a more efficient man-machine interaction.

0285One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing these methods are shown in <figref idref="f0009 f0019">Figures 5A-5K</figref>

0286<figref idref="f0130 f0134">Figures 6A-6E</figref> are flow diagrams illustrating a method 600, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0287While performing method 600, the electronic device displays (602) a messaging user interface (e.g., of a messaging application) on the display. The messaging user interface includes a conversation transcript of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device). See for example, <figref idref="f0009">Figure 5A</figref>, conversation transcript 5004 in messaging user interface 5002. The electronic device receives (604) a first message within the messaging session from an electronic device (e.g., a second electronic device) that corresponds to another user included in the messaging session. For example, in <figref idref="f0009">Figure 5A</figref>, message 5006 is a first message.

0288In response to receiving the first message, the electronic device displays (606) the first message (e.g., message 5006, <figref idref="f0009">Figure 5A</figref>) in a first message region (e.g., message region 5008-1, <figref idref="f0009">Figure 5A</figref>) in the conversation transcript (e.g., conversation transcript 5004, <figref idref="f0009">Figure 5A</figref>) on the display. As used herein, a message region is a message region, bubble, platter, or other container for a message in a conversation transcript of a messaging session. The electronic device furthermore detects (608) a first input by a first contact (e.g., contact 5010, <figref idref="f0009">Figure 5A</figref>) at a location on the touch-sensitive surface that corresponds to a location of the first message region in the conversation transcript. For example, the first contact may be a tap gesture, long press gesture, light press gesture, or deep press gesture on the first message region or on a hidden hit region for the first message region.

0289Next, in response to detecting the first input, the electronic device displays (610) displaying an acknowledgement selection affordance (e.g., acknowledgement selection affordance 5012, <figref idref="f0010">Figure 5B</figref>) at a location in the messaging interface that corresponds to the first message region. The acknowledgement selection affordance displays a plurality of acknowledgement options. For example, see acknowledgement options 5014-1 to 5014-6 in <figref idref="f0010">Figure 5B</figref>. In some embodiments, the acknowledgement selection affordance is an acknowledgement selection platter displayed proximate to and/or overlapping the first message region. In some embodiments, in accordance with a determination that a characteristic intensity of the contact is above a first intensity threshold, the acknowledgement selection affordance is displayed. In some embodiments, a user can reveal additional acknowledgement options, in addition to an initially displayed set of acknowledgement options 5014, by performing a predefined input gesture, such as a gesture that includes repeated deep presses, a drag gesture, etc.

0290In some embodiments, the plurality of acknowledgement options include (612) graphical icons that display at least one of a heart, a thumbs up, a thumbs down, a "HA!", a "!!", and/or a question mark. (See, for example, acknowledgement options 5014-1 to 5014-6 shown in <figref idref="f0010">Figure 5B</figref>).

0291In some embodiments, method 600 includes, in response to detecting the first input, transmitting (614) information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to display an acknowledgement-preparation indicator for a corresponding first message region in a conversation transcript that corresponds to the messaging session (e.g., causing the other devices in the messaging session to display an acknowledgement region with animated ellipses marks adjacent to and/or partially overlapping the corresponding first message region in the conversation transcript of the at least one other user's device, analogous to what is shown in <figref idref="f0015">Figure 5G</figref>).

0292After detecting and responding to the first input, the electronic device detects (616) a second input by a second contact (e.g., contact 5016, <figref idref="f0010">Figure 5B</figref>) at a location on the touch-sensitive surface that corresponds to a location of a first acknowledgement option (e.g., acknowledgement option 5014-2, <figref idref="f0010">Figure 5B</figref>) in the acknowledgement selection affordance (e.g., acknowledgement selection affordance 5012, <figref idref="f0010">Figure 5B</figref>). Optionally, detecting the second contact is accomplished by, for example, detecting a tap gesture, light press gesture, deep press gesture, or lift off on the first acknowledgement option or on a hidden hit region for the first acknowledgement option. In some embodiments, the first contact and the second contact are distinct contacts, such as contacts in two different tap gestures made by the same finger. In some embodiments, the first contact and the second contact are different parts of the same continuous contact with the touch-sensitive surface, such as a long press, light press, or deep press on the first message region followed by a drag to the first acknowledgement option and lift off at the first acknowledgement option.

0293In response to detecting the second input, the electronic device applies (618) the first acknowledgement option to the first message region. For example, <figref idref="f0011">Figure 5C</figref> shows a first acknowledgment option 5014-2 applied to a first message region. In some embodiments, the electronic device also ceases to display the acknowledgement selection affordance in response to detecting the second input.

0294In some embodiments, applying (618) the first acknowledgement option to the first message region includes displaying (620) the first acknowledgement option at a location adjacent to and/or partially overlapping the first message region. See, for example, <figref idref="f0011">Figure 5C</figref>, which shows first acknowledgement option 5014-2 applied to, and in this case, partially overlapping, a corresponding first message region.

0295Optionally, in some embodiments, in response to detecting the second input, the electronic device transmits (622) information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to apply the first acknowledgement option to a corresponding first message region in a conversation transcript that corresponds to the messaging session. In some embodiments, this is accomplished by transmitting information that causes the other devices in the messaging session to display the first acknowledgement option adjacent to and/or partially overlapping the corresponding first message region in the conversation transcript of the at least one other user's device. See, for example, <figref idref="f0016">Figure 5H</figref>, which shows the conversation transcript as displayed on one of the other devices in the messaging session, including first acknowledgement option 5014-2 applied to (and in this case, partially overlapping) a corresponding first message region. In some embodiments, the first acknowledgement option (e.g., first acknowledgement option 5014-2) replaces an acknowledgement-preparation indicator (e.g., acknowledgement-preparation indicator 5020, <figref idref="f0015">Figure 5G</figref>) for a corresponding first message region (e.g., via an animated transition).

0296In some embodiments, the first acknowledgement option is displayed in an acknowledgement region that has a different shape from the first message region (e.g., as shown in <figref idref="f0011">Figure 5C</figref>, a respective message region 5008-1 for a message from another user is rectangular and/or includes a first indicator that the first message is from the other user (e.g., a tail section "&lt;" pointing towards a first side of the display), whereas a respective acknowledgement region 5018 is circular and/or includes a second indicator that the acknowledgement is from the user (e.g., a tail section "Oo" pointing towards a second side of the display, opposite the first side)).

0297In some embodiments, method 600 includes, after applying the first acknowledgement option to the first message region (and, in some embodiments, ceasing to display the acknowledgement selection affordance), performing a sequence of operations (632-658) that includes detecting (632) a third input by a third contact (e.g., contact 5022, <figref idref="f0011">Figure 5C</figref>) at a location on the touch-sensitive surface that corresponds to a location of the first message region (or, in some embodiments, the first acknowledgement option). In some embodiments, detecting (632) the third input includes detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the first message region (or the first acknowledgement option) or on a hidden hit region for the first message region (or the first acknowledgement option).

0298In such embodiments, method 600 further includes, in response to detecting (632) the third input by the third contact at the location on the touch-sensitive surface that corresponds to the location of the first message region (or, in some embodiments, the first acknowledgement option), displaying (634) an acknowledgement editing interface (e.g., acknowledgement editing interface 5024, <figref idref="f0012">Figure 5D</figref>). Optionally, the acknowledgement editing interface is displayed on top of and/or in place of the conversation transcript.

0299In such embodiments, method 600 further includes detecting (650) one or more inputs to the acknowledgement editing interface (e.g., detecting contact 5026, <figref idref="f0013">Figure 5E</figref>), editing (652) (e.g., changing or deleting) an acknowledgement option for the first message region in accordance with the detected one or more inputs; ceasing (654) to display the acknowledgement editing interface; displaying (656) the first message region in the conversation transcript with an edited acknowledgement; and transmitting (658) information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to display a corresponding first message region with the edited acknowledgement in a conversation transcript that corresponds to the messaging session. For example, <figref idref="f0012">Figure 5D</figref> shows an acknowledgement editing interface 5024, with an indication (e.g., highlighting or greying out) that acknowledgement option 5014-2 was previously selected. <figref idref="f0013">Figure 5E</figref> shows an input, contact 5026, selecting a different, second acknowledgement option 5014-1, and <figref idref="f0014">Figure 5F</figref> shows a message region in a conversation transcript with the edited acknowledgment (i.e., with second acknowledgement option 5014-1 displayed instead of first acknowledgement option 5014-2).

0300In some embodiments, in addition to displaying (634) the acknowledgement editing interface in response to detecting (632) the third input by the third contact, method 600 includes, in response to detecting the third input by the third contact, ceasing (636) to display (or dimming) the conversation transcript, an example of which is shown in <figref idref="f0013">Figure 5E</figref>.

0301Furthermore, in some embodiments, in response to detecting the third input by the third contact, method 600 includes displaying (638) the first message region in the acknowledgement editing interface. For example, <figref idref="f0013">Figure 5E</figref> shows an example in which the first message region is displayed in the acknowledgement editing interface, without displaying any other message regions in the conversation transcript in the acknowledgement editing interface. In some embodiments, the first message region is initially displayed in the acknowledgement editing interface at a same location as the first message region was displayed in the conversation transcript immediately prior to detecting the third input.

0302In some embodiments, in addition to displaying (634) the acknowledgement editing interface in response to detecting (632) the third input by the third contact, method 600 includes, in response to detecting the third input by the third contact, displaying the acknowledgement selection affordance that includes the plurality of acknowledgement options in the acknowledgement editing interface, wherein the first acknowledgement option is visually distinguished (e.g., highlighted) from the other acknowledgement options in the plurality of acknowledgement options to indicate that the first acknowledgement option is currently selected. For example, <figref idref="f0012">Figure 5D</figref> shows that acknowledgement editing interface 5024 includes the acknowledgement selection affordance (similar to affordance 5012, <figref idref="f0010">Figure 5B</figref>), which includes a plurality of acknowledgement options 5014).

0303In some embodiments in addition to displaying (634) the acknowledgement editing interface in response to detecting (632) the third input by the third contact, method 600 includes, in response to detecting the third input by the third contact, displaying (642) a menu in the acknowledgement editing interface that includes activatable editing options for the first message region. For example, <figref idref="f0012">Figure 5D</figref> shows an edit menu 5028 which includes a "Copy" icon 530 to copy content of the first message region. While not shown in <figref idref="f0012">Figure 5D</figref>, edit menu 5028 optionally include additional activatable editing options, such as a "Delete" icon to delete the currently applied acknowledgement option.

0304In some embodiments, method 600 includes, while displaying the messaging user interface as described above, concurrently displaying (660) on the display (A) a second message region (e.g., message region 5008-2, <figref idref="f0582">Figure 51</figref>) in the conversation transcript, wherein (1) at least some of the users in the messaging session have selected the first acknowledgement option for the second message region, and (2) at least some of the users in the messaging session have selected a second acknowledgement option for the second message region, distinct from the first acknowledgement option; and (B) one or more indicia (e.g., indicia 5036) that users in the messaging session have selected a plurality of acknowledgements options for the second message region. In the example shown in <figref idref="f0582">Figure 51</figref>, indicia 5036 is a stack of overlapping acknowledgement option icons, but could alternatively be a plurality of individual acknowledgement option icons. As shown in <figref idref="f0582">Figure 51</figref>, indicia 5036 is optionally adjacent to and/or partially overlapping the second message region 5008-02. In some embodiments, for a given acknowledgement option that was selected, the selections are stacked if the acknowledgement option was selected by more than a threshold number of user users in the messaging session (e.g., by more than 2, 3, or 4 users).

0305In such embodiments (i.e., showing a second message region and the indicia that users in the messaging session have selected a plurality of acknowledgements options for the second message region), method 600 includes detecting (662) an input by a contact at a location on the touch-sensitive surface that corresponds to a location of the second message region (e.g., contact 5034 on second message region 5008-2, <figref idref="f0582">Figure 51</figref>). Alternatively, the detected input corresponds to a location of the one or more indicia that users in the messaging session have selected a plurality of acknowledgements options for the second message region. In some embodiments, detecting (662) the input includes detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the second message region or on a hidden hit region for the second message region.

0306In response to detecting the input by the contact at the location on the touch-sensitive surface that corresponds to the location of the second message region, method 600 includes displaying (664) a user interface that includes a tally for each type of acknowledgement option selected by users in the messaging session. For example, as shown in <figref idref="f0018">Figure 5j</figref>, the user interface includes tallies 5040-1, 5040-2, 5040-3 for three distinct acknowledgement options selected by users in the messaging session. Alternatively, in some embodiments, in response to detecting the input by the contact at the location on the touch-sensitive surface that corresponds to the location of the second message region, the device displays a user interface that includes a tally affordance (e.g., as a menu option), which when activated, displays the tally for each type of acknowledgement option selected by users in the messaging session.

0307In some embodiments, method 600 includes, while displaying the tally for each type of acknowledgement option selected by users in the messaging session, detecting (666) an input by a contact at a location on the touch-sensitive surface that corresponds to a tally for the first acknowledgement option for the second message region. For example, referring to <figref idref="f0018">Figure 5J</figref>, the input may select tally 5040-1. In some embodiments, detecting (666) the input at a location on the touch-sensitive surface that corresponds to a tally includes detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the tally for the first acknowledgement option, or on a stack of icons (e.g., avatars) that correspond to users in the messaging session that selected the first acknowledgement option, or on a hidden hit region for this tally or this stack of icons.

0308In such embodiments, method 600 further includes, in response to detecting (666) the input by the contact at a location on the touch-sensitive surface that corresponds to the tally for the first acknowledgement option for the second message region, displaying (668) icons (e.g., avatars) that represent users that selected the first acknowledgement option for the second message region. For example, as shown in <figref idref="f0019">Figure 5K</figref>, the user interface displayed by the device in response to an input selecting tally 5040-1 (<figref idref="f0018">Figure 5J</figref>), includes a display of the icons (e.g., avatars) that represent users that selected the first acknowledgement option for the second message region, which replaces display of the tally for each type of acknowledgement option selected by users in the messaging session (shown in <figref idref="f0018">Figure 5J</figref>).

0309It should be understood that the particular order in which the operations in <figref idref="f0130 f0134">Figures 6A-6E</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 1000, 1200, 1400, 1600, 1800) are also applicable in an analogous manner to method 600 described above with respect to <figref idref="f0130 f0134">Figures 6A-6E</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0135">Figure 7</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

0311As shown in <figref idref="f0135">Figure 7</figref>, an electronic device 700 includes a display unit 702 configured to display a messaging user interface on the display unit, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user; a touch-sensitive surface unit 704 configured to detect contacts; and a processing unit 706 coupled with the display unit 702 and the touch-sensitive surface unit 704. In some embodiments, the processing unit 706 includes a detecting unit 708, a display enabling unit 710, a ceasing unit 712, a transmitting unit 714, a receiving unit 716, an applying unit 718, and an editing unit 720.

0312The processing unit 706 is configured to: receive a first message within the messaging session from an electronic device that corresponds to another user included in the messaging session (e.g., with the receiving unit 716); in response to receiving the first message, enable display of the first message in a first message region in the conversation transcript on the display unit 702 (e.g., with the display enabling unit 710); detect a first input by a first contact at a location on the touch-sensitive surface unit 704 that corresponds to a location of the first message region in the conversation transcript (e.g., with the detecting unit 708); in response to detecting the first input, enable display of an acknowledgement selection affordance at a location in the messaging interface that corresponds to the first message region (e.g., with the display enabling unit 710), wherein the acknowledgement selection affordance displays a plurality of acknowledgement options; detect a second input by a second contact at a location on the touch-sensitive surface unit 704 that corresponds to a location of a first acknowledgement option in the acknowledgement selection affordance (e.g., with the detecting unit 708); and, in response to detecting the second input, apply the first acknowledgement option to the first message region (e.g., with the applying unit 718).

0313In some embodiments, applying the first acknowledgement option to the first message region includes displaying the first acknowledgement option at a location adjacent to and/or partially overlapping the first message region.

0314In some embodiments, the first acknowledgement option is displayed in an acknowledgement region that has a different shape from the first message region.

0315In some embodiments, the processing unit 706 is further configured to: in response to detecting the first input, transmit information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to display an acknowledgement-preparation indicator for a corresponding first message region in a conversation transcript that corresponds to the messaging session (e.g., with the transmitting unit 714).

0316In some embodiments, the processing unit 706 is further configured to: in response to detecting the second input, transmit information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to apply the first acknowledgement option to a corresponding first message region in a conversation transcript that corresponds to the messaging session (e.g., with the transmitting unit 714).

0317In some embodiments, the processing unit 706 is further configured to: after applying the first acknowledgement option to the first message region: detect a third input by a third contact at a location on the touch-sensitive surface unit 704 that corresponds to a location of the first message region (e.g., with the detecting unit 708); in response to detecting the third input by the third contact at the location on the touch-sensitive surface unit 704 that corresponds to the location of the first message region, enable display of an acknowledgement edit interface (e.g., with the display enabling unit 710); detect one or more inputs to the acknowledgement editing interface (e.g., with the detecting unit 708); edit an acknowledgement option for the first message region in accordance with the detected one or more inputs (e.g., with the editing unit 720); cease to display the acknowledgement editing interface (e.g., with the ceasing unit 712); enable display of the first message region in the conversation transcript with an edited acknowledgement (e.g., with the display enabling unit 710); and transmit information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to display a corresponding first message region with the edited acknowledgement in a conversation transcript that corresponds to the messaging session (e.g., with the transmitting unit 714).

0318In some embodiments, the processing unit 706 is further configured to: in response to detecting the third input by the third contact, cease to display the conversation transcript (e.g., with the ceasing unit 712).

0319In some embodiments, the processing unit 706 is further configured to: in response to detecting the third input by the third contact, enable display of the first message region in the acknowledgement editing interface (e.g., with the display enabling unit 710).

0320In some embodiments, the processing unit 706 is further configured to: in response to detecting the third input by the third contact, enable display of the acknowledgement selection affordance that includes the plurality of acknowledgement options in the acknowledgement editing interface (e.g., with the display enabling unit 710), wherein the first acknowledgement option is visually distinguished from the other acknowledgement options in the plurality of acknowledgement options to indicate that the first acknowledgement option is currently selected.

0321In some embodiments, the processing unit 706 is further configured to: in response to detecting the third input by the third contact, enable display of a menu in the acknowledgement editing interface that includes activatable editing options for the first message region (e.g., with the display enabling unit 710).

0322In some embodiments, the plurality of acknowledgement options include graphical icons that display at least one of a heart, a thumbs up, a thumbs down, a "HA!", a "!!", and/or a question mark.

0323In some embodiments, the processing unit 706 is further configured to: concurrently enable display on the display unit 702 (e.g., with the display enabling unit 710) of: a second message region in the conversation transcript, wherein at least some of the users in the messaging session have selected the first acknowledgement option for the second message region and at least some of the users in the messaging session have selected a second acknowledgement option for the second message region, distinct from the first acknowledgement option; and one or more indicia that users in the messaging session have selected a plurality of acknowledgements options for the second message region; and detect an input by a contact at a location on the touch-sensitive surface unit 704 that corresponds to a location of the second message region (e.g., with the detecting unit 708); and, in response to detecting the input by the contact at the location on the touch-sensitive surface unit 704 that corresponds to the location of the second message region, enable display of a user interface that includes a tally for each type of acknowledgement option selected by users in the messaging session (e.g., with the display enabling unit 710).

0324In some embodiments, the processing unit 706 is further configured to: while the tally for each type of acknowledgement option selected by users in the messaging session is displayed, detect an input by a contact at a location on the touch-sensitive surface unit 704 that corresponds to a tally for the first acknowledgement option for the second message region (e.g., with the detecting unit 708); and in response to detecting the input by the contact at a location on the touch-sensitive surface unit 704 that corresponds to the tally for the first acknowledgement option for the second message region, enable display of icons that represent users that selected the first acknowledgement option for the second message region (e.g., with the display enabling unit 710).

0325The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0326The operations described above with reference to <figref idref="f0130 f0134">Figures 6A-6E</figref> are, optionally, implemented by components depicted in <figref idref="f0001">Figures 1A-1B</figref> or <figref idref="f0135">Figure 7</figref>. For example, detection operations 606 and 616 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Editing previously sent messages

0327<figref idref="f0136 f0138">Figures 8A-8C</figref> are flow diagrams of a process for editing a previously sent messages in a messaging session, in accordance with some embodiments. More specifically, the methods relate to displaying an interface for editing a message, displaying a revised version of the message, ceasing to display the pre-revision version of the message, and/or displaying at least one indication of the revision.

0328Message transcripts can become cluttered with messages containing typographical errors followed by messages correcting the previous errors. By allowing editing of previously transmitted messages, the conversational flow of the transcript is better preserved and makes it easier for conversation participants to follow the conversation.

0329One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing these methods are shown in <figref idref="f0020 f0028">Figures 5L-5T</figref>.

0330<figref idref="f0136 f0138">Figures 8A-8C</figref> are flow diagrams illustrating a method 800, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0331In accordance with some embodiments, method 800 includes displaying (802) a messaging user interface (e.g., user interface 5002, <figref idref="f0020">Figure 5L</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0020">Figure 5L</figref>) of a messaging session between a user of the electronic device and at least one other user, and a first message region (e.g., message region 5044, <figref idref="f0020">Figure 5L</figref>) that includes a first message (e.g., message 5046-1, <figref idref="f0020">Figure 5L</figref>) in the messaging session that was sent from the electronic device of the user to the at least one other user in the messaging session.

0332The method further includes detecting (804) a first input (e.g., input 5048) that corresponds to a request to edit the first message. In some embodiments, the device detects the first input by detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the first message region (e.g., message region 5044, <figref idref="f0020">Figure 5L</figref>) or on a hidden hit region for the first message region that results in display of a message editing interface for the first message (e.g., message editing interface 5052, <figref idref="f0022">Figure 5N</figref>). In some embodiments, the device detects a tap gesture, light press gesture, or deep press gesture on an editing affordance in the messaging user interface or on a hidden hit region for the editing affordance that results in display of a message editing interface for the first message (e.g., as shown in <figref idref="f0022">Figure 5N</figref>). In some embodiments, if the first message is the most recently sent message by the user, the device detects a tap gesture, long press gesture, light press gesture, or deep press gesture on a message-input area (or on an editing affordance in the message-input area) that results in display of a message editing interface for the first message (e.g., as shown in <figref idref="f0022">Figure 5N</figref>).

0333In some embodiments, in response to detecting an input by the contact at the location on the touch-sensitive surface that corresponds to the location of the first message region (e.g., first message region 5044, <figref idref="f0020">Figure 5L</figref>), the device displays a user interface that includes an edit affordance (e.g., an edit affordance, displayed as a menu option, as shown in <figref idref="f0021">Figure 5M</figref>), which when activated, displays the message editing interface for the first message (e.g., message editing interface 5052, <figref idref="f0022">Figure 5N</figref>). In some embodiments, while the first message region is displayed with a list of activatable options for the first message (<figref idref="f0021">Figure 5M</figref>), the device detects an input (e.g., input 5050, <figref idref="f0021">Figure 5M</figref>) that activates an edit option, such as a tap gesture on the edit option, that results in display of a message editing interface for the first message.

0334Method 800 includes, in response to detecting the first input (e.g., input 5048, <figref idref="f0020">Figure 5L</figref>, or input 5050, <figref idref="f0021">Figure 5M</figref>), displaying (806) a message editing interface (e.g., message editing interface 5052, <figref idref="f0022">Figure 5N</figref>) for the first message that includes the first message (e.g., message 5046-1, <figref idref="f0022">Figure 5N</figref>), a keyboard (e.g., keyboard 5054, <figref idref="f0022">Figure 5N</figref>), and an update affordance (e.g., update affordance 5056, <figref idref="f0022">Figure 5N</figref>), and while displaying (808) the message editing interface for the first message, detecting (810) one or more inputs that revise the first message, displaying (814) a revised version of the first message; and detecting (816) an input that activates the update affordance.

0335In some embodiments, displaying (806) the editing interface replaces display of the conversation transcript (e.g., compare <figref idref="f0020">Figures 5L</figref> and <figref idref="f0022">5N</figref>). In some embodiments, display of the editing interface (e.g., as shown in <figref idref="f0022">Figure 5N</figref>) replaces display of a user interface that includes a list of activatable options for the first message (e.g., as shown in <figref idref="f0021">Figure 5M</figref>).

0336In some embodiments, detecting (810) one or more inputs that revise the first message includes detecting inputs on the keyboard that add and/or delete text in the first message, and/or detecting inputs that select, cut, copy, and or paste text. For example, in <figref idref="f0022">Figures 5N</figref> and <figref idref="f0023">5O</figref>, the editing replaces the term "ridiculous" with "ride". In some embodiments, detecting (816) an input that activates the update affordance includes detecting a tap gesture at a location that corresponds to the update affordance. In some embodiments, the update affordance is adjacent to the revised version of the first message in the message editing interface (rather than in the keyboard or in a new message input area).

0337Method 800 further includes, in response (818) to detecting the input that activates the update affordance: ceasing (820) to display the message editing interface for the first message; displaying (822) the revised version of the first message in place of the first message in the conversation transcript; displaying (824) at least one indication of the revision of the first message in the conversation transcript; and transmitting (832) the revised version of the first message to one or more electronic devices (e.g., a second electronic device) that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the revised version of the first message in place of the first message in a conversation transcript that corresponds to the messaging session, with at least one indication of the revision of the first message in the conversation transcript. For example, activating update affordance 5056, shown in <figref idref="f0022">Figure 5N</figref>, causes the device to cease the display of message editing interface 5052, for example returning to the display of messaging user interface 5002, including conversation transcript 5004, as shown in <figref idref="f0023">Figure 5O</figref>. Further, as shown in <figref idref="f0023">Figure 5O</figref>, the revised version of the first message 5046-2 is now displayed, along with an indication 5058-1 (e.g., a shadow, indicating the existence of an earlier version of the first message) of the revision of the first message in the conversation transcript. <figref idref="f0579 f0580 f0581">Figure 50</figref> also shows a second example of an indication 5058-2 of the revision of the first message in the conversation transcript, which in this example is the displayed term "Edited". As shown in <figref idref="f0026">Figure 5R</figref>, the revised version 5046-2 of the first message is transmitted to and displayed by at least one electronic device corresponding to at least one other user included in the messaging session, and includes a first indication 5058-1 (e.g., a message region shadow) of the revision of the first message as well as a second indication 5058-2 (e.g., the displayed term "Edited") of the revision of the first message.

0338In some embodiments of method 800, detecting (810) the one or more inputs that revise the first message includes detecting (812) an input at a location (e.g., location 5057, <figref idref="f0022">Figure 5N</figref>) that corresponds to the first message in the message editing interface (e.g., a tap on the first message in the first message region) to select a position in the first message for text selection, text insertion, or the text deletion. The insertion point or location 5057 shown in <figref idref="f0022">Figure 5N</figref> is adjacent the term "ridiculous", which, as shown in <figref idref="f0023">Figure 5O</figref>, the user edits so as to replace that term with the term "ride."

0339In some embodiments, the at least one indication (e.g., indication 5058-1 and/or indication 5058-2, <figref idref="f0023">Figure 5O</figref>) of the revision of the first message in the conversation transcript is not removable from the conversation transcript (826). Making such indications not removable may be important for giving users confidence that the conversation transcript accurately reflects the messages sent by the participants.

0340In some embodiments, the at least one indication of the revision of the first message includes a graphical element at a location of the first message region (828). For example, as shown in <figref idref="f0023">Figure 5O</figref>, indication 5058-1 is a shadow region behind the first message region; alternatively state, indication 5058-1 is a shadow region that is partially overlapped by the first message region.

0341In some embodiments, the at least one indication of the revision of the first message includes text adjacent to the first message region (830). For example, as shown in <figref idref="f0023">Figure 5O</figref>, indication 5058-1 is text (e.g., "Edited") displayed below the first message region that contains the revised version of the first message.

0342In some embodiments, method 800 includes, after editing the first message, detecting (834) an input (e.g., input 5060, <figref idref="f0023">Figure 5O</figref>) that corresponds to a request to edit the revised version (e.g., version 5046-2) of the first message, and in response to detecting the input that corresponds to the request to edit the revised version of the first message, performing a set of operations, including displaying a message editing interface (e.g., the interface shown in <figref idref="f0026">Figure 5R</figref>) for the revised version of the first message that includes the revised version of the first message, the keyboard, and the update affordance, an example of which is shown in <figref idref="f0026">Figure 5R</figref>. In such embodiments, method 800 further includes, while displaying the message editing interface for the revised version of the first message: detecting one or more inputs that further revise the first message; displaying a further revised version of the first message; and detecting an input that activates the update affordance. In such embodiments, method 800 further includes, , in response to detecting the input that activates the update affordance: ceasing to display the message editing interface for the revised version of the first message; displaying the further revised version of the first message in place of the revised version of first message in the conversation transcript; displaying at least one indication that the first message in the conversation transcript has been revised (e.g., in some embodiment, two shadow regions are displayed behind the first message region, which are partially overlapped by the first message region, to indicate that the first message has been revised twice); and transmitting the further revised version of the first message to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the further revised version of the first message in place of the revised version of first message in a conversation transcript that corresponds to the messaging session, with at least one indication that the first message in the conversation transcript has been revised.

0343In some embodiments, method 800 includes, after editing the first message, detecting (836) an input that corresponds to a request to see versions of the first message, and in response to detecting the input that corresponds to the request to see versions of the first message, displaying a user interface that includes a current version of the first message and one or more prior versions of the first message. For example, in response to input 5060 in <figref idref="f0023">Figure 5O</figref>, the device may display the user interface shown in <figref idref="f0024">Figure 5P</figref>, in which display of the conversation transcript is suppressed except for the revised version of the first message 5046-2, and a menu 5062 or list of editing options. In this example, the displayed menu 5062 or list of editing options includes a copy affordance 5064, a show edits affordance 5066, a delete affordance 5068 and a display more options affordance 5070. In the example shown in <figref idref="f0024">Figure 5P</figref>, input 5072 (e.g., a tap gesture) is detected at the location on the touch-sensitive surface that corresponds to the location of the "show edits" affordance 5066, which when activated, displays a user interface 5074 (<figref idref="f0025">Figure 5Q</figref>) that includes current version 5046-1 of the first message as well as a prior version 5046-2, as shown in <figref idref="f0025">Figure 5Q</figref>.

0344It should be understood that the particular order in which the operations in <figref idref="f0136 f0138">Figures 8A-8C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 1000, 1200, 1400, 1600, 1800) are also applicable in an analogous manner to method 800 described above with respect to <figref idref="f0136 f0138">Figures 8A-8C</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0345In accordance with some embodiments, <figref idref="f0139">Figure 9</figref> shows a functional block diagram of an electronic device 900 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0139">Figure 9</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

0346As shown in <figref idref="f0139">Figure 9</figref>, an electronic device 900 includes a display unit 902 configured to display a messaging user interface on the display 902, the messaging user interface including: a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and a first message region that includes a first message in the messaging session that was sent from the electronic device of the user to the at least one other user in the messaging session; a touch-sensitive surface unit 904 configured to detect contacts; and a processing unit 906 coupled with the display unit 902 and the touch-sensitive surface unit 904. In some embodiments, the processing unit 906 includes a detecting unit 908, a display enabling unit 910, a ceasing unit 912, and a transmitting unit 914.

0347The processing unit 906 is configured to: detect a first input that corresponds to a request to edit the first message (e.g., with the detecting unit 908); in response to detecting the first input, enable display of a message editing interface for the first message that includes the first message, a keyboard, and an update affordances (e.g., with the display enabling unit 910); while the message editing interface for the first message is displayed: detect one or more inputs that revise the first message (e.g., with the detecting unit 908); enable display of a revised version of the first message (e.g., with the display enabling unit 910); and detect an input that activates the update affordance (e.g., with the detecting unit 908); and, in response to detecting the input that activates the update affordance: cease to display the message editing interface for the first message (e.g., with the ceasing unit 912); enable display of the revised version of the first message in place of the first message in the conversation transcript (e.g., with the display enabling unit 910); enable display of at least one indication of the revision of the first message in the conversation transcript (e.g., with the display enabling unit 910); and transmit the revised version of the first message to one or more electronic devices that correspond to the at least one other user included in the messaging session (e.g., with the transmitting unit 914), wherein the one or more electronic devices display the revised version of the first message in place of the first message in a conversation transcript that corresponds to the messaging session, with at least one indication of the revision of the first message in the conversation transcript.

0348In some embodiments, the at least one indication of the revision of the first message in the conversation transcript is not removable from the conversation transcript.

0349In some embodiments, the at least one indication of the revision of the first message includes a graphical element at a location of the first message region.

0350In some embodiments, the at least one indication of the revision of the first message includes text adjacent to the first message region.

0351In some embodiments, detecting the one or more inputs that revise the first message include detecting an input at a location that corresponds to the first message in the message editing interface to select a position in the first message for text selection, text insertion, or the text deletion.

0352In some embodiments, the processing unit 906 is further configured to: after editing the first message, detect an input that corresponds to a request to edit the revised version of the first message (e.g., with the detecting unit 908); in response to detecting the input that corresponds to the request to edit the revised version of the first message, enable display of a message editing interface for the revised version of the first message that includes the revised version of the first message, the keyboard, and the update affordance (e.g., with the display enabling unit 910); while the message editing interface for the revised version of the first message is displayed: detect one or more inputs that further revise the first message (e.g., with the detecting unit 908); enable display of a further revised version of the first message (e.g., with the display enabling unit 910); and detect an input that activates the update affordance (e.g., with the detecting unit 908); and, in response to detecting the input that activates the update affordance: cease to display the message editing interface for the revised version of the first message (e.g., with the ceasing unit 912); enable display of the further revised version of the first message in place of the revised version of first message in the conversation transcript (e.g., with the display enabling unit 910); enable display of at least one indication that the first message in the conversation transcript has been revised (e.g., with the display enabling unit 910); and transmit the further revised version of the first message to one or more electronic devices that correspond to the at least one other user included in the messaging session (e.g., with the transmitting unit 914), wherein the one or more electronic devices display the further revised version of the first message in place of the revised version of first message in a conversation transcript that corresponds to the messaging session, with at least one indication that the first message in the conversation transcript has been revised.

0353In some embodiments, the processing unit 906 is further configured to: after editing the first message, detect an input that corresponds to a request to see versions of the first message (e.g., with the detecting unit 908); and, in response to detecting the input that corresponds to the request to see versions of the first message, enable display of a user interface that includes a current version of the first message and one or more prior versions of the first message (e.g., with the display enabling unit 910).

0354The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0355The operations described above with reference to <figref idref="f0136 f0138">Figures 8A-8C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0139">Figure 9</figref>. For example, detection operations 804 and 810 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0356<figref idref="f0140 f0141">Figures 10A-10B</figref> are flow diagrams of a process for editing a previously sent message in a messaging session, in accordance with some embodiments. One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing these methods are shown in <figref idref="f0020 f0028">Figures 5L-5T</figref>.

0357<figref idref="f0140 f0141">Figures 10A-10B</figref> are flow diagrams illustrating a method 1000, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0358In accordance with some embodiments, method 1000 includes displaying (1002) a messaging user interface (e.g., user interface 5002, as shown in <figref idref="f0020">Figure 5L</figref> or <figref idref="f0023">5O</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0020">Figure 5L</figref> or <figref idref="f0023">5O</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device), and a first message region (e.g., message region 5044, <figref idref="f0579 f0580 f0581">Figure 50</figref>) that includes a current version of a first message (e.g., message version 5046-2, <figref idref="f0023">Figure 5O</figref>) in the messaging session, wherein the conversation transcript includes an indication (e.g., indication 5058-1, or 5058-2, as describe above) that the current version of the first message is a revised version of the first message in the conversation transcript. The original version of the first message is, for example, a previously transmitted message or a previously received message.

0359Method 1000 further includes detecting (1004) an input that corresponds to a request to see versions of the first message (e.g., input 5060, as shown in <figref idref="f0023">Figure 5O</figref>), and in response to detecting the input that corresponds to the request to see versions of the first message, displaying (1008) a versions user interface (e.g., user interface 5074, <figref idref="f0025">Figure 5Q</figref>) that includes the current version of the first message (e.g., version 5046-1) and one or more prior versions of the first message (e.g., version 5046-2).

0360In some embodiments, detecting (1004) the input includes the device detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the first message region or on a hidden hit region for the first message region that results in display of a user interface with current and prior versions of the first message (e.g., user interface 5074, <figref idref="f0025">Figure 5Q</figref>).

0361In some embodiments, in response to detecting an input by the contact at the location on the touch-sensitive surface that corresponds to the location of the first message region (input 5060, <figref idref="f0023">Figure 5O</figref>), the device displays a user interface that includes an affordance (e.g., "show edits" menu option, <figref idref="f0024">Figure 5P</figref>), which when activated, displays current and prior versions of the first message (e.g., <figref idref="f0025">Figure 5Q</figref>). In some embodiments, while the first message region is displayed with a list of activatable options for the revised version of the first message (as shown in <figref idref="f0024">Figure 5P</figref>), the device detects an input that activates a "show edits" option (e.g., input 5072 on show edits option 5066, <figref idref="f0024">Figure 5P</figref>), such as a tap gesture on the "show edits" option, that results in display of a user interface with current and prior versions of the first message (e.g., <figref idref="f0025">Figure 5Q</figref>).

0362In some embodiments, the input that corresponds to the request to see versions of the first message is detected (1006) while displaying the current version of the first message (e.g., without displaying other messages in the conversation transcript, as shown in <figref idref="f0027">Figure 5S</figref>) and a menu that includes an affordance (e.g., a "show edits" option, <figref idref="f0027">Figure 5S</figref>), which when activated results in display of the user interface (e.g., as shown in <figref idref="f0028">Figure 5T</figref>) that includes the current version (e.g., version 5046-2, <figref idref="f0028">Figure 5T</figref>) of the first message and one or more prior versions of the first message (e.g., version 5046-1, <figref idref="f0028">Figure 5T</figref>). In some embodiments, the menu includes an affordance (e.g., a "edit" option), which when activated results in display of a message editing interface for the current version of the first message that includes the current version of the first message, a keyboard, and an update affordance.

0363In some embodiments, in the versions user interface (e.g., 5074, <figref idref="f0025">Figure 5Q</figref>), the current version of the first message (e.g., 5046-1) is visually distinguished (1010) from other versions of the first message. For example, in various embodiments the current version of the first message is visually distinguished from other versions of the first message by different shading, background color, background pattern, font color, and/or region boundary color, or the like.

0364In some embodiments, the versions user interface (e.g., 5074, <figref idref="f0025">Figure 5Q</figref>) includes (1012) the current version of the first message (e.g., 5046-1), an original version of the first message (e.g., 5046-2), and at least one version of the first message that was revised prior to the current version of the first message (not shown in the figures).

0365In some embodiments, the versions user interface (e.g., 5074, <figref idref="f0025">Figure 5Q</figref>) includes (1014) an affordance (e.g., a "Done" option 5082, <figref idref="f0025">Figure 5Q</figref>), which when activated causes redisplay of the conversation transcript in the user interface (e.g., as shown in <figref idref="f0026">Figure 5R</figref>). Typically, activation of this affordance also causes display of the versions user interface to cease.

0366In some embodiments, the versions user interface includes (1016) an affordance (e.g., Edit icon 5080, <figref idref="f0025">Figure 5Q</figref>), which when activated causes display of a message editing interface (e.g., as shown in <figref idref="f0026">Figure 5R</figref>) for the current version of the first message that includes the current version of the first message (5046-2), a keyboard (5054), and an update affordance (5056). Typically, activation of this affordance also causes display of the versions user interface to cease.

0367It should be understood that the particular order in which the operations in <figref idref="f0140">Figures 10A-10B</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1200, 1400, 1600, 1800) are also applicable in an analogous manner to method 1000 described above with respect to <figref idref="f0140 f0141">Figures 10A-10B</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 1000 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0368In some embodiments, method 100 includes, while displaying the versions user interface (e.g., 5074, <figref idref="f0025">Figure 5Q</figref>), detecting (1018) an input (e.g., input 5076 or 5078, <figref idref="f0025">Figure 5Q</figref>, to edit either the current version 5046-1 or the original version 5046-2) on a respective version of the first message (e.g., detecting a tap gesture, long press gesture, light press gesture, or deep press gesture on the current version, an intermediate version, or the original version of the first message); and, in response to detecting an input on the respective version of the first message: displaying a message editing interface (e.g., a message editing interface as shown in <figref idref="f0022">Figure 5N</figref>) for the respective version of the first message that includes the respective version (5046) of the first message, a keyboard (5054), and an update affordance (5056); and ceasing to display the versions user interface.

0369In accordance with some embodiments, <figref idref="f0142">Figure 11</figref> shows a functional block diagram of an electronic device 1100 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0142">Figure 11</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

0370As shown in <figref idref="f0142">Figure 11</figref>, an electronic device 1100 includes a display unit 1102 configured to display a messaging user interface on the display unit, the messaging user interface including: a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and a first message region that includes a current version of a first message in the messaging session, wherein the conversation transcript includes an indication that the current version of the first message is a revised version of the first message in the conversation transcript; a touch-sensitive surface unit 1104 configured to detect contacts; and a processing unit 1106 coupled with the display unit 1102 and the touch-sensitive surface unit 1104. In some embodiments, the processing unit 1106 includes a detecting unit 1108, a display enabling unit 1110, and a ceasing unit 1112.

0371The processing unit 1106 is configured to: detect an input that corresponds to a request to see versions of the first message (e.g., with the detecting unit 1108); and, in response to detecting the input that corresponds to the request to see versions of the first message, enable display of a versions user interface that includes the current version of the first message and one or more prior versions of the first message (e.g., with the display enabling unit 1110).

0372In some embodiments, the input that corresponds to the request to see versions of the first message is detected while displaying the current version of the first message and a menu that includes an affordance, which when activated results in display of the user interface that includes the current version of the first message and one or more prior versions of the first message.

0373In some embodiments, in the versions user interface, the current version of the first message is visually distinguished from other versions of the first message.

0374In some embodiments, the versions user interface includes the current version of the first message, an original version of the first message, and at least one version of the first message that was revised prior to the current version of the first message.

0375In some embodiments, the versions user interface includes an affordance, which when activated causes redisplay of the conversation transcript.

0376In some embodiments, the versions user interface includes an affordance, which when activated causes display of a message editing interface for the current version of the first message that includes the current version of the first message, a keyboard, and an update affordance.

0377In some embodiments, the processing unit 1106 is further configured to: while the versions user interface is displayed, detect an input on a respective version of the first message (e.g., with the detecting unit 1108); and, in response to detecting an input on the respective version of the first message: enable display of a message editing interface for the respective version of the first message that includes the respective version of the first message, a keyboard, and an update affordance (e.g., with the display enabling unit 1110); and cease to display the versions user interface (e.g., with the ceasing unit 1112).

0378The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0379The operations described above with reference to <figref idref="f0140 f0141">Figures 10A-10B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0142">Figure 11</figref>. For example, detection operations 1004 and 1018 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Message impact effects

0380<figref idref="f0143 f0147">Figures 12A-12E</figref>, described in more detail below, relate generally to methods for applying an impact effect option to a message input. More specifically, these figures relate to methods of displaying an interface that includes multiple impact effect options in response to input received in a message input area of a messaging user interface. A preview that applies an impact effect option to the message input is displayed. Information including the message input and the applied impact effect option is transmitted to at least one remote electronic device (e.g., a device of at least one other user). Oftentimes, additional information that could be conveyed with verbal tone or facial expressions is lost when only the text of a conversation is available to determine the intent of the speaker. The methods described here with respect to <figref idref="f0143 f0147">Figures 12A-12E</figref> allow additional information to be added to the transcript to convey additional sentiment that might be missing otherwise.

0381One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing these methods are shown in <figref idref="f0029 f0047">Figures 5U-5AM</figref> and <figref idref="f0048 f0066">5AN-5BF</figref>.

0382<figref idref="f0143 f0147">Figures 12A-12E</figref> are flow diagrams illustrating a method 1200, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0383In accordance with some embodiments, method 1200 includes displaying (1202) a messaging user interface (e.g., user interface 5002, as shown in <figref idref="f0029">Figure 5U</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0029">Figure 5U</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device), and a message-input area (e.g., 5100, <figref idref="f0029">Figure 5U</figref>) that includes a first message input (e.g., text, stickers, images, and/or other graphics entered by a user of the electronic device in the message-input area, but not yet sent to the at least one other user in the messaging session). Method 1200 includes, while displaying the messaging user interface, detecting a first input by a first contact (e.g., input 5102, <figref idref="f0029">Figure 5U</figref>) at a location on the touch-sensitive surface that corresponds to a location in the message-input area. In some embodiments, the first input includes a gesture (e.g., a swipe gesture) received at the message-input area. In some embodiments, the message-input area includes an impact selection affordance (e.g., 5104, <figref idref="f0029">Figure 5U</figref>) and the location of the contact corresponds to the impact selection affordance. In some embodiments, detecting the first input includes the device detecting a tap gesture, long press gesture, light press gesture, or deep press gesture by the contact at a location that corresponds to the impact selection affordance. Furthermore, in some embodiments, different inputs (e.g., a tap gesture, and a deep press gesture) on the impact selection affordance cause the user interface to transition to different subsequent user interfaces. For example, in some embodiments, a tap gesture on affordance 5104, <figref idref="f0029">Figure 5U</figref> or <figref idref="f0032">5X</figref>, sends the message input 5102 in message input area 5100 as a message, while a deep press input 5108-1, 5108-2, 5108-3, as shown in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>, when detected by the electronic device, causes the messaging application to display an impact selection interface 5110, <figref idref="f0035">Figure 5AA</figref>.

0384Thus, method 1200 further includes, in response to detecting the first input by the first contact, displaying (1206) an impact selection interface (e.g., impact selection interface 5110, <figref idref="f0035">Figure 5AA</figref>) that includes a plurality of impact effect options (e.g., impact effect options 5112-1 through 5112-4 are displayed in place of the messaging user interface or on top of the messaging user interface). In some embodiments, the displayed plurality of impact effect options (e.g., 5112-1 to 5112-4, <figref idref="f0035">Figure 5AA</figref>) are a subset, less than all, of a set of impact effect options. In some embodiments, the set of impact effect options includes options that are applied to an individual message region (e.g., "region effect" options) and options that are applied to the entire displayed conversation transcript when a message is initially displayed in the messaging session (e.g., "full-screen effect" options). In some embodiments, the displayed plurality of impact effect options includes at least some of the region effect options and none of the full-screen effect options. In some embodiments, the region effect options include: an option that slams down a message in the conversation transcript when the message is initially displayed (e.g., "slam" option 5112-4, <figref idref="f0035">Figure 5AA</figref>); an option that increases the size of the message in the conversation transcript, at least when the message is initially displayed (e.g., "loud" option 5112-3, <figref idref="f0035">Figure 5AA</figref>); an option that decreases the size of the message in the conversation transcript, at least when the message is initially displayed (e.g., "gentle" option 5112-2, <figref idref="f0035">Figure 5AA</figref>, and <figref idref="f0054">Figures 5AT</figref> through 5AW); and an option that conceals the content of a message in the conversation transcript ("invisible ink" option 5112-1, <figref idref="f0035">Figure 5AA</figref>).

0385In some embodiments, the full-screen effect options include two or more of the following options: an option that displays balloons in the conversation transcript when the message is initially displayed ("balloons"); an option that displays confetti in the conversation transcript when the message is initially displayed ("confetti"); an option that displays fireworks in the conversation transcript when the message is initially displayed ("fireworks"); an option that displays the message in focus and blurs the rest of the conversation transcript when the message is initially displayed ("focus"); an option that displays one or more spotlight beams moving in the conversation transcript when the message is initially displayed ("spotlight" or "drop the mic"); an option that displays multiple copies of the message over the conversation transcript when the message is initially displayed ("echo"); an option that displays a shooting star in the conversation transcript when the message is initially displayed ("shooting star"); an option that displays multiple laser beams (e.g., as shown in <figref idref="f0104 f0105 f0106">Figures 5CR through 5CT</figref>) moving in the conversation transcript when the message is initially displayed ("lasers"); and an option that displays a heart inflating from the message when the message is initially displayed ("metallic heart").

0386Method 1200 further includes, while displaying the impact selection interface, detecting (1222) a second input by a second contact at a location on the touch-sensitive surface that corresponds to a location of a first impact effect option in the plurality of impact effect options. Examples of the second input are input 5108-4, <figref idref="f0035">Figure 5AA</figref>, input 5108-5, <figref idref="f0036 f0038">Figures 5AB-5AD</figref>, and input 5108-6, <figref idref="f0039 f0040">Figures 5AE-5AF</figref>. In some embodiments, the first contact and the second contact are distinct contacts, such as contacts in two different tap gestures made by the same finger, or a deep press gesture on a send affordance followed by a tap gesture on a first impact effect option. In some embodiments, the first contact and the second contact are different parts of the same continuous contact with the touch-sensitive surface, such as a long press, light press, or deep press on the impact selection affordance (e.g., deep press input 5108-1, 5108-2, 5108-3, on impact selection affordance 5104, as shown in <figref idref="f0032">Figures 5X</figref>, <figref idref="f0033">5Y</figref> and <figref idref="f0034">5Z</figref>) followed by a drag to the first impact effect option (e.g., input 5108-4 on impact effect option 5112-1, <figref idref="f0035">Figure 5AA</figref>) and then pausing or deep pressing on the first impact effect option.

0387Method 1200 also includes, in response to detecting the second user input by a second contact (e.g., second input 5108-6, <figref idref="f0039">Figure 5AE</figref>) displaying (1224) a preview (e.g., in the impact selection interface, 5110, <figref idref="f0039">Figure 5AE</figref>) that applies the first impact effect option to the first message input. <figref idref="f0039">Figure 5AE</figref> shows a preview of the slam option being applied to first message input ("Congratulations!") in response to a second input 5108-6 respective by a second contact at a location on the touch-sensitive surface that corresponds to a location of a first impact effect option (i.e., the slam option). In some embodiments, the preview applies the first impact effect to a message region that includes the first message input (e.g., as shown in <figref idref="f0039">Figure 5AE</figref>). In some embodiments, the preview applies the first impact effect to all (or substantially all) of the display screen, which includes a message region with the first message, for a full-screen effect, an example of which is shown by the sequence of user interface images in <figref idref="f0058 f0059 f0060 f0061 f0062 f0063 f0064 f0065 f0066">Figures 5AX through 5BF. Figures 5AX through 5BF</figref> show the progression of the "slam" effect of a first message input ("Hell No!!"), starting with the first message input displayed shown enlarged, rotated and with a dark background (<figref idref="f0058">Figure 5AX</figref>), then displayed even larger and with a somewhat lighter background (<figref idref="f0059">Figure 5AY</figref>), then less enlarged and rotated at a different angle than before (<figref idref="f0060">Figure 5AZ</figref>), then shown with further reduced enlargement and with blurry borders (<figref idref="f0061">Figure 5BA</figref>), then shown with reduced size a different background and a different rotation (<figref idref="f0062">Figure 5BB</figref>) and then with a sequence of different shadows around the message region (<figref idref="f0063">Figures 5BC</figref>, <figref idref="f0064">5BD</figref>, <figref idref="f0065">5BE</figref>) until the first message input is shown at normal (default) size, not rotated, and with a normal (default) background (<figref idref="f0066">Figure 5BF</figref>).

0388In some embodiments, while the preview of a respective impact effect option is displayed, the location in the impact selection interface that corresponds to the respective impact effect option includes an affordance (e.g., send affordance 5118, <figref idref="f0036">Figure 5AB</figref>) for sending a message (with the first message input) with the respective impact effect option.

0389With regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, in some embodiments, the impact selection interface includes (1208) both a region effect options affordance (e.g., affordance 5114, <figref idref="f0035">Figure 5AA</figref>), which when activated causes display of impact effect options for a message containing the first message input, and a full-screen effect options affordance (e.g., affordance 5116, <figref idref="f0035">Figure 5AA</figref>), which when activated causes display of a preview of one impact effect option that is applied to the entire displayed conversation transcript when a message containing the first message input is displayed in the messaging session. Typically, there will be a plurality of full-screen effect options, but only one of them is previewed at any one time, in response to activation of a full-screen effect options affordance.

0390In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1210) at least one impact effect option that applies an image (e.g., a shaded oval or cloud) with an area that is larger than an area of a message region that contains the first message input to the message region that contains the first message input (e.g., displaying the image behind the message region that contains the first message input). Examples of this effect are shown in <figref idref="f0039">Figures 5AE</figref>, and <figref idref="f0040">5AF</figref>.

0391In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1212) at least one impact effect option that increases or decreases a size of a message region that contains the first message input relative to a size (e.g., a default size) of the message region that contains the first message input when no impact effect option is selected. For example, <figref idref="f0036">Figure 5AB</figref> shows an example in which an impact effect option is displayed with a message region that contains the first message input having a decreased size relative to a default size of the message region, while <figref idref="f0037">Figure 5AC</figref> shows an example in which an impact effect option is displayed with the message region that contains the first message input having an increased size relative to a default size of the message region.

0392In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1214) at least one impact effect option that is configured to have a message region that contains the first message input interact with other message regions in the displayed conversation transcript when the message region that contains the first message input is displayed (e.g., the other message regions shake and/or bounce upon display of the message region that contains the first message input in the conversation transcript, to increase the impact of the arriving message). For example, the sequence of user interfaces illustrated in <figref idref="f0062 f0065">Figures 5BB-5BE</figref> show message regions other than the message region with the first message input (e.g., "Hell No!!) being moved (e.g., moved closer together, and caused to partially overlap) to increase the visual impact of the arriving message.

0393In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1216) at least one impact effect option that is configured to display an animation when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session. In some embodiments, the animation is a "shake" animation (e.g., as shown in <figref idref="f0042 f0043">Figures 5AH-5AI</figref>) that moves the message region between two or more locations, such as side-to-side and/or up-and-down animation. In some embodiments, the animation increases a size of the message region from an initially displayed size in the conversation transcript (e.g., as shown in the sequence of <figref idref="f0045">Figures 5AK</figref>, <figref idref="f0046">5AL</figref>, <figref idref="f0047">5AM</figref>, and in the sequence of <figref idref="f0048 f0053">Figures 5AN-5AS</figref>).

0394In some embodiments, the animation increases the size of the message region beyond a final size that is displayed at the end of the animation (thereby overshooting the final size) and then reduces the size of the message region to the final size (e.g., as shown in the sequence of <figref idref="f0048 f0053">Figures 5AN-5AS</figref>). In some embodiments, the final size of the message region is larger or smaller than a (default) size of the message region that contains the first message input when no impact effect option is selected. In some embodiments, an impact effect option that conceals the content of a message region displays an animation that includes moving particles (e.g., virtual sand particles) within the message region to indicate that the content of the message is concealed (e.g., as shown in <figref idref="f0077 f0078">Figure 5BQ-5BR</figref>).

0395In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1218) at least one impact effect option that is configured to display an animation when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session, wherein the animation concurrently moves the message region that contains the first message input and other message regions in the conversation transcript. For example, the other message regions shake and/or bounce upon display of the message region that contains the first message input in the conversation transcript, to increase the impact of the arriving message. The sequence of user interfaces illustrated in <figref idref="f0062 f0066">Figures 5BB-5BF</figref> show such an example in which both the message region with the first message input and other message regions are moved in the conversation transcript in accordance with the "slam" effect option (5112-4 in <figref idref="f0035">Figures 5AA</figref>, <figref idref="f0037">5AC</figref>).

0396In some embodiments, with regard to displaying (1206) an impact selection interface that includes a plurality of impact effect options, discussed above, the plurality of impact effect options includes (1220) at least one impact effect option that is configured to trigger one or more tactile outputs (e.g., to provide haptic feedback) when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session. For example, In some embodiments, a first impact effect option (e.g., the "slam" option 5112-4, <figref idref="f0035">Figure 5AA</figref>) has a smaller amplitude tactile output than a second impact effect option (e.g., the "loud" option 5112-3, <figref idref="f0035">Figure 5AA</figref>).

0397In some embodiments, with regard to displaying (1224) a preview (e.g., in the impact selection interface, 5110, <figref idref="f0039">Figure 5AE</figref>), the preview (e.g., in the impact selection interface 5110, <figref idref="f0039">Figure 5AE</figref>) that applies the first impact effect option to the first message input repeats periodically (1226). For example, an animation shown in the preview is repeated every N (e.g., 2, 3, or 4) seconds, until a subsequent user input is detected.

0398In some embodiments, after displaying the preview, method 1200 includes detecting (1228) lift off of the second contact at a location on the touch-sensitive surface that corresponds to the first impact effect option; and, in response to detecting lift off of the second contact at the location on the touch-sensitive surface that corresponds to the first impact effect option: ceasing to display the impact selection interface (e.g., impact selection interface, 5110, <figref idref="f0039">Figure 5AE</figref>); displaying a message region that contains the first message input in the conversation transcript (and, in some embodiments, applying the first impact effect option to the message region and/or the conversation transcript, as shown in <figref idref="f0042">Figure 5AH</figref>); and transmitting information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to (A) display a message region that contains the first message input in a conversation transcript that corresponds to the messaging session, and (B) apply the first impact effect option (e.g., as shown in <figref idref="f0045">Figure 5AK</figref>). The first impact effect is optionally applied to the message region that contains the first message input and/or to the displayed conversation transcript.

0399In some embodiments, after displaying the preview, method 1200 includes detecting (1230) detecting a third input by a third contact at a location on the touch-sensitive surface that corresponds to the first impact effect option (e.g., detecting a tap gesture, long press gesture, light press gesture, or deep press gesture by the contact at a location that corresponds to the first impact effect option, such as at a send affordance for the first impact option). For example, <figref idref="f0041">Figure 5AG</figref> shows a third input 5108-7 on a send affordance, at a location corresponding to a user-selected impact effect option, in this case the "slam" option.

0400In such embodiments, method 1200 includes, in response to detecting the third input by the third contact at the location on the touch-sensitive surface that corresponds to the first impact effect option: ceasing to display the impact selection interface; displaying a message region that contains the first message input in the conversation transcript (and, in some embodiments, applying the first impact effect option to the message region and/or the conversation transcript, as shown in <figref idref="f0042">Figure 5AH</figref>); and transmitting information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to (A) display a message region that contains the first message input in a conversation transcript that corresponds to the messaging session, and (B) apply the first impact effect option (e.g., as shown in <figref idref="f0045">Figure 5AK</figref>). The first impact effect is optionally applied to the message region that contains the first message input and/or to the displayed conversation transcript.

0401In some embodiments, after displaying the preview, method 1200 includes detecting (1232) lift off of the second contact (e.g., lift-off of second input 5108-6, as shown in <figref idref="f0039">Figure 5AE</figref> or <figref idref="f0040">5AF</figref>) at a location on the touch-sensitive surface that corresponds to the first impact effect option; and, in response to detecting lift off of the second contact at a location on the touch-sensitive surface that corresponds to the first impact effect option: selecting the first impact effect option for a message that contains the first message input; ceasing to display the impact selection interface; and displaying (e.g., as shown in <figref idref="f0042">Figure 5AH</figref>) the conversation transcript of the messaging session and the message-input area that includes a first message input.

0402In such embodiments, method 1200 includes, detecting a third input (e.g., a tap gesture at a location that corresponds to a send affordance, such as third input 5108-7, <figref idref="f0041">Figure 5AG</figref>); and in response to detecting the third input: displaying a message region (e.g., as shown in <figref idref="f0042">Figure 5AH</figref>) that contains the first message input in the conversation transcript (and, in some embodiments, applying the first impact effect option to the message region and/or the conversation transcript); and transmitting information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to (A) display a message region that contains the first message input in a conversation transcript that corresponds to the messaging session, and (B) apply the first impact effect option (e.g., as shown in <figref idref="f0045">Figure 5AK</figref>). The first impact effect is optionally applied to the message region that contains the first message input and/or to the displayed conversation transcript.

0403In some embodiments, after displaying the preview, method 1200 includes detecting (1234) a third input by a third contact at a location on the touch-sensitive surface that corresponds to the first impact effect option (e.g., detecting a tap gesture, long press gesture, light press gesture, or deep press gesture by the contact at a location that corresponds to the first impact effect option, such as at a send affordance for the first impact option). For example, <figref idref="f0041">Figure 5AG</figref> shows a third input 5108-7 on a affordance, at a location corresponding to a user-selected impact effect option, in this case the "slam" option.

0404In such embodiments (1234), method 1200 includes, in response to detecting the third input by the third contact at the location on the touch-sensitive surface that corresponds to the first impact effect option: selecting the first impact effect option for a message that contains the first message input; ceasing to display the impact selection interface; and displaying the conversation transcript of the messaging session and the message-input area that includes a first message input (e.g., first message input 5102 in message-input area 5008, as shown in <figref idref="f0042">Figure 5AH</figref>). Further, method 1200 includes detecting a fourth input (e.g., a tap gesture at a location that corresponds to a send affordance, which optionally may be the same affordance as the impact option select affordance, or alternatively may a distinct affordance from the impact option select affordance); and in response to detecting the fourth input: (A) displaying a message region that contains the first message input in the conversation transcript (and, in some embodiments, applying the first impact effect option to the message region and/or the conversation transcript); and transmitting information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to (A) display a message region that contains the first message input in a conversation transcript that corresponds to the messaging session, and (B) apply the first impact effect option (e.g., as shown in <figref idref="f0045">Figure 5AK</figref>). The first impact effect is optionally applied to the message region that contains the first message input and/or to the displayed conversation transcript.

0405Optionally, a user of the messaging application can preview more than one impact effect option that is applied to the entire displayed conversation transcript before making a final selection of an impact effect option. In some embodiments, method 1200 includes, while the message-input area is empty (1236), detecting an input that enters text in the message-input area (e.g., message input area 5100, <figref idref="f0029">Figure 5U</figref>); and, in response to detecting the input that enters text in the message-input area, displaying an impact selection affordance (e.g., impact selection affordance 5104, in message-input area 5100), wherein activation of the impact selection affordance is configured to cause display of the impact selection interface.

0406In some embodiments, method 1200 includes, while a preview of an impact effect option that is applied to the entire displayed conversation transcript is displayed (e.g., a preview of a first full screen effect option, such as displaying balloons (e.g., balloons 5152-1, as shown in <figref idref="f0088">Figure 5CB</figref>) floating upwards in the conversation transcript for a birthday message, as shown in <figref idref="f0089">Figure 5CC</figref>, and <figref idref="f0094 f0101">Figures 5CH-5CO</figref>), detecting (1238) an input (e.g., swipe gesture 5156, <figref idref="f0089">Figure 5CC</figref>) that activates display of a preview of another impact effect option that is applied to the entire displayed conversation transcript; and, in response to detecting the input that activates display of the preview of another impact effect option that is applied to the entire displayed conversation transcript, displaying the preview of the second impact effect option that is applied to the entire displayed conversation transcript (e.g., displaying a preview of a second full screen effect option, such as a display of confetti for a "Congratulations!" message, as shown in <figref idref="f0090 f0091">Figures 5CD-5CE</figref>, or fireworks exploding in the conversation transcript for a "Happy New Year" message, as shown in <figref idref="f0102 f0109">Figures 5CP-5CW</figref>). As shown in <figref idref="f0088">Figures 5CB</figref> and <figref idref="f0089">5CC</figref>, the user interface may include an effect option indicator 5154 (sometimes called page dots) to indicate which full screen effect option is currently selected or is currently being previewed, and also to indicate how many full screen effect options are available and which one of those options in a sequence of the full screen effect options is currently being viewed.

0407Optionally, a user of the messaging application can preview more than one impact effect option before making a final selection of an impact effect option. In some embodiments, method 1200 includes, while displaying the impact selection interface (e.g., impact selection interface 5110, as shown in <figref idref="f0035">Figure 5AA</figref>), detecting (1240) an input by a contact (e.g., input 5108-4) at a location on the touch-sensitive surface that corresponds to a location of a second impact effect option in the plurality of impact effect options; and, in response to detecting the user input by the contact at the location on the touch-sensitive surface that corresponds to the location of a second impact effect option, displaying a preview (e.g., in the impact selection interface) that applies the second impact effect option to the first message input. In some embodiments, the preview applies the second impact effect to a message region that includes the first message input.

0408The sequence of <figref idref="f0094 f0101">Figures 5CH-5CO</figref> shows an example of a balloons full screen effect being displayed when a message ("Happy Birthday!!!!!") containing a corresponding enhanced message content trigger is received. Similarly, the sequence of <figref idref="f0102 f0109">Figures 5CP-5CW</figref> shows an example of a fireworks full screen effect being displayed when a message ("Happy New Year!!!") containing a corresponding enhanced message content trigger is received.

0409In some embodiments, method 1200 includes determining (1242) whether an electronic device that corresponds to another user in the messaging session is capable of applying the first impact effect option (or, more generally, capable of applying any of the plurality of impact effect options) to a message in the messaging session, and, in accordance with a determination that the electronic device that corresponds to another user in the messaging session is not capable of applying the first impact effect option to a message in the messaging session, displaying a notification on the display of the electronic device of the user about the first impact effect option (e.g., a notification that the electronic device that corresponds to the other user in the messaging session is not capable of applying the first impact effect option, or any impact effect option, to a message in the messaging session). Optionally, in accordance with a determination that the electronic device that corresponds to another user in the messaging session is capable of applying the first impact effect option to a message in the messaging session, method 1200 includes forgoing displaying the notification.

0410In some embodiments, prior to transmitting information that causes one or more electronic devices that correspond to the at least one other user included in the messaging session to display a message region that contains the first message input, the electronic device of the user determines whether the electronic device corresponding to the at least one other user is capable of applying the first impact effect option to the message region. If not, the electronic device of the user displays a notification indicating that the other user will not see the effect.

0411It should be understood that the particular order in which the operations in <figref idref="f0143 f0147">Figures 12A-12E</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed.

0420In some embodiments, the impact selection interface includes a region effect options affordance, which when activated causes display of impact effect options for a message containing the first message input, and a full-screen effect options affordance, which when activated causes display of a preview of one impact effect option that is applied to the entire displayed conversation transcript when a message containing the first message input is displayed in the messaging session.

0421In some embodiments, the processing unit 1306 is further configured to: while a preview of an impact effect option that is applied to the entire displayed conversation transcript is displayed, detect an input that activates display of a preview of another impact effect option that is applied to the entire displayed conversation transcript (e.g., with the detecting unit 1308); and, in response to detecting the input that activates display of the preview of another impact effect option that is applied to the entire displayed conversation transcript, enable display of the preview of the second impact effect option that is applied to the entire displayed conversation transcript (e.g., with the display enabling unit 1310).

0422In some embodiments, the processing unit 1306 is further configured to: while displaying the impact selection interface, detect an input by a contact at a location on the touch-sensitive surface unit 1304 that corresponds to a location of a second impact effect option in the plurality of impact effect options (e.g., with the detecting unit 1308); and, in response to detecting the user input by the contact at the location on the touch-sensitive surface unit 1304 that corresponds to the location of a second impact effect option, enable display of a preview that applies the second impact effect option to the first message input (e.g., with the display enabling unit 1310).

0423In some embodiments, the plurality of impact effect options includes at least one impact effect option that applies an image with an area that is larger than an area of a message region that contains the first message input to the message region that contains the first message input.

0424In some embodiments, the plurality of impact effect options includes at least one impact effect option that increases or decreases a size of a message region that contains the first message input relative to a size of the message region that contains the first message input when no impact effect option is selected.

0425In some embodiments, the plurality of impact effect options includes at least one impact effect option that is configured to have a message region that contains the first message input interact with other message regions in the displayed conversation transcript when the message region that contains the first message input is displayed.

0426In some embodiments, the plurality of impact effect options includes at least one impact effect option that is configured to display an animation when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session.

0427In some embodiments, the plurality of impact effect options includes at least one impact effect option that is configured to display an animation when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session, wherein the animation concurrently moves the message region that contains the first message input and other message regions in the conversation transcript.

0428In some embodiments, the plurality of impact effect options includes at least one impact effect option that is configured to trigger one or more tactile outputs when a message region that contains the first message input is displayed in a conversation transcript that corresponds to the messaging session.

0429In some embodiments, the preview that applies the first impact effect option to the first message input repeats periodically.

0430In some embodiments, the processing unit 1306 is further configured to: determine whether an electronic device that corresponds to another user in the messaging session is capable of applying the first impact effect option to a message in the messaging session (e.g., with the determining unit 1318), and, in accordance with a determination that the electronic device that corresponds to another user in the messaging session is not capable of applying the first impact effect option to a message in the messaging session, enable display of a notification on the display unit 1302 of the electronic device of the user about the first impact effect option (e.g., with the display enabling unit 1310).

0431The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0432The operations described above with reference to <figref idref="f0143 f0147">Figures 12A-12E</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0148">Figure 13</figref>. For example, detection operations 1204 and 1222 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Concealed Message Interaction

0433<figref idref="f0149 f0150">Figures 14A-14B</figref> are flow diagrams of a process for interacting with concealed messages, in accordance with some embodiments. More specifically, these figures relate to methods of displaying an interface that includes one or more screen elements to conceal received message text within the message region. In response to input received at a location corresponding to the message region, the received message is at least partially revealed. This allows messages to be transmitted and viewed privately where messages may be viewed in a crowded location, etc. By requiring an additional action to view the message text, inadvertent disclosure of the contents is avoided.

0434One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing these methods are shown in <figref idref="f0067 f0076">Figures 5BG-5BP</figref> and <figref idref="f0077 f0087">5BQ-5CA</figref>.

0435<figref idref="f0149 f0150">Figures 14A-14B</figref> are flow diagrams illustrating a method 1400, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0436In accordance with some embodiments, method 1400 includes displaying (1402) a messaging user interface (e.g., user interface 5002, as shown in <figref idref="f0068">Figure 5BH</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0068">Figure 5BH</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device) including a first other user, and a message region (5008, <figref idref="f0068">Figure 5BH</figref>) in the conversation transcript for a message (e.g., message 5126) received from the first other user, the message region including one or more screen elements (e.g., screen elements 5124, <figref idref="f0068">Figure 5BH</figref>) that conceal the message received from the first other user.

0437In some embodiments, the received message is sent by another device, a user of which has applied an "invisible ink" effect to the message. In some embodiments, that is accomplished using an impact selection interface 5110, <figref idref="f0067">Figure 5BG</figref>, that includes a plurality of impact effect options (e.g., impact effect options 5112-1 through 5112-4, described above with respect to <figref idref="f0035">Figure 5AA</figref>). In some embodiments, the set of impact effect options includes options that are applied to an individual message region (e.g., "region effect" options) and options that are applied to the entire displayed conversation transcript when a message is initially displayed in the messaging session (e.g., "full-screen effect" options). In some embodiments, the displayed plurality of impact effect options includes an option that conceals the content of a message in the conversation transcript ("invisible ink" option 5112-1, <figref idref="f0035">Figure 5AA</figref>, indicated in <figref idref="f0067">Figure 5BG</figref> by an empty message region). In some embodiments, the invisible ink option includes an affordance (e.g., send affordance 5118, <figref idref="f0067">Figure 5BG</figref>) for sending a message (with user-specified message input) with the respective impact effect option. In some embodiments, impact selection interface 5110, <figref idref="f0067">Figure 5BG</figref>, includes a cancel affordance 5120 for canceling the selection of any impact effect options and returning the messaging application to either a prior user interface of the messaging application or a predefined user interface of the messaging application.

0438In some embodiments, the one or more screen elements (5124) that conceal the message are (1404) moving particles (e.g., displayed images of moving particles). In some embodiments, the device displays an animation that includes moving particles (e.g., virtual sand particles) within the message region to conceal the content of the message.

0439In some embodiments, the message region (5008, <figref idref="f0068">Figure 5BH</figref>) with the concealed message has (1406) a message region outline that is distinct from an outline on message regions in the conversation transcript that do not have concealed messages. In one example, the message region with the concealed message has a dotted line outline, whereas conventional message regions (e.g., message regions that do not have impact effects applied to them, such as the invisible ink effect) in the conversation transcript have solid line outlines.

0440Method 1400 further includes detecting (1408) a first input by a contact (e.g., a swipe or drag gesture input 5128-a, <figref idref="f0068">Figure 5BH</figref>) at a location on the touch-sensitive surface that corresponds to the message region with the concealed message; and, after detecting the first input by the contact, revealing (1416) the concealed message in the message region. For example, as shown in <figref idref="f0068">Figures 5BH</figref>, <figref idref="f0069">5BI</figref>, <figref idref="f0070">5BJ</figref> and <figref idref="f0071">5BK</figref>, respective portions of the message 5126 are revealed in response to the drag gesture input 5128-a, 5128-b, 5128-c, 5128-d progressing from a first portion of the message region 5008 to another portion of the message region 5008. Continuing with the example, as shown in <figref idref="f0020">Figure 5L</figref>, when the drag gesture 5128 is completed, or ends, or after the passage of a predefined time, the message in the message region 5008 is again concealed.

0441In some embodiments, the first input is a drag gesture (e.g., input 5128-a) by the contact at a location that corresponds to the message region with the concealed message.

0442In some embodiments, detecting (1408) the first input by the contact includes detecting (1412) a drag gesture (e.g., input 5128-a, <figref idref="f0068">Figure 5BH</figref>) by the contact at a location that corresponds to the message region with the concealed message, and method 1400 includes dynamically removing (1412) portions of the one or more screen elements that conceal the message, thereby revealing corresponding portions of the message, in accordance with the movement of the contact in the drag gesture. In some embodiments, portions of the one or more screen elements (e.g., screen elements 5124) are removed that are within a predetermined distance of the contact in the drag gesture. In some embodiments, after a given portion of the message is revealed (e.g., after passage of a predetermined amount of time, such as 0.5, 1, 2, 3, 4, or 5 seconds), the given portion is concealed again (e.g., by applying one or more screen elements that conceal the given portion).

0443In some embodiments, the electronic device includes (1414) one or more sensors configured to detect intensities of contacts on the touch-sensitive surface, and the first input (e.g., input 5128-a) is a press input (e.g., a light press or a deep press) by the contact at a location that corresponds to the message region with the concealed message.

0444In some embodiments, the electronic device includes (1418) one or more sensors configured to detect intensities of contacts on the touch-sensitive surface, and detecting the first input by the contact includes detecting an increase in intensity of the contact (e.g., input 5130-a, 5130-b, 5130-c, with increasing intensity, as shown in <figref idref="f0073">Figures 5BM</figref>, <figref idref="f0074">5BN</figref> and <figref idref="f0075">5BO</figref>) at a location that corresponds to the message region (5008, <figref idref="f0073">Figure 5BM</figref>) with the concealed message. In such embodiments, method 1400 includes: dynamically removing portions of the one or more screen elements (5124) that conceal the message (e.g., as shown in <figref idref="f0073">Figure 5BM</figref>), thereby revealing corresponding portions of the message, in accordance with the increase in intensity of the contact (e.g., as shown in the sequence of <figref idref="f0073">Figures 5BM</figref>, <figref idref="f0074">5BN</figref> and <figref idref="f0075">5BO</figref>). In some embodiments, portions of the one or more screen elements (5124) are removed that are closest to the contact and then, as the intensity of the contact increases, portions that are farther and farther from the contact are removed, until the entire message is revealed, as shown in the sequence of <figref idref="f0073">Figures 5BM</figref>, <figref idref="f0074">5BN</figref> and <figref idref="f0075">5BO</figref>. In some embodiments, in accordance with a decrease in intensity of the contact during the input, the device dynamically adds portions of one or more screen elements, thereby concealing corresponding portions of the message, as shown in the progression from <figref idref="f0075 f0076">Figure 5BO to Figure 5BP</figref>.

0445In some embodiments, method 1400 includes, in response to detecting the first input by the contact, displaying (1420) an authentication prompt (e.g., text that says "Please enter a fingerprint or passcode" or the like) and/or an authentication interface (e.g., a passcode screen). In such embodiments, method 1400 further includes receiving an authentication input (e.g., receiving a passcode or fingerprint input); in accordance with a determination that the authentication input satisfies authentication criteria, revealing the concealed message in the message region; and in accordance with a determination that the authentication input does not satisfy the authentication criteria, keeping the message in the message region concealed.

0446In some embodiments, the device determines whether the user is authorized to see the message, and, in accordance with a determination that the user is authorized to see the message, the message is revealed. In some embodiments, the determination is performed in response to detecting the first user input. In some embodiments, the determination is performed in response to receiving the concealed message. In some embodiments, the determination is performed when a messaging application is loaded or when the messaging application receives focus (e.g., when a user interface of the messaging application is displayed and is enabled to received user inputs). In some embodiments, the determination is performed when the user provides authentication information to the device (e.g., authentication is performed when the user unlocks the device using a code, password, and/or fingerprint). In some embodiments (e.g., on a device with multiple users) authentication is performed each time a new user provides authentication information.

0447In some embodiments, determining whether the user is authorized to reveal the message includes performing a biometric authentication. In some embodiments, authentication is performed when user provides a fingerprint to unlock the device. In some embodiments, user is prompted to provide a fingerprint or passcode when the concealed message is received or when user attempts to access the concealed message.

0448In some embodiments, prior to sending a concealed message from a device, the device authenticates the sender (e.g., by checking sender authentication credentials). For example, prior to sending a concealed message (such as a message with an "invisible ink" impact effect option), the sending device checks whether a passcode or fingerprint provided by a user corresponds to an authorized user, such as the primary user of the device. In some embodiments, the sender is prompted to provide a passcode and/or biometric authentication (e.g., a fingerprint) just prior to sending the concealed message (e.g., in response to a user activating a send icon or selecting an option to conceal the message, like an "invisible ink" impact effect option). In some embodiments, if the device authenticates the sender, then the concealed message is sent or is enabled to be sent, whereas if the device does not authenticate the sender, then the concealed message is prevented from being sent.

0449In some embodiments, method 1400 includes, after revealing the concealed message in the message region, concealing (1422) the message received from the first other user. For example, after a concealed message in message region 5008 has been revealed, as shown in the sequence of <figref idref="f0068 f0071">Figures 5BH-5BK</figref>, the message in message region is again concealed, as shown in <figref idref="f0072">Figure 5BL</figref>. In another example, the sequence of <figref idref="f0077 f0082">Figures 5BQ-5BV</figref>, show a message being gradually revealed, as shown in <figref idref="f0077 f0078 f0079 f0080">Figures 5BQ to 5BT</figref>, and then gradually concealed, as shown in <figref idref="f0080 f0081 f0082">Figures 5BT to 5BV</figref>. In some embodiments, the message is concealed again in response to detecting termination of the first input by the contact. In some embodiments, the message is concealed again after a predetermined time (e.g., 2 seconds, 5 seconds, or a predetermined amount of time that between two and five seconds) has elapsed since the first input by the contact terminates. In some embodiments, the message is concealed again after a predetermined time (e.g., 2 seconds, 5 seconds, or a predetermined amount of time that between two and five seconds) has elapsed since the message was revealed.

0450It should be understood that the particular order in which the operations in <figref idref="f0149 f0150">Figures 14A-14B</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1600, 1800) are also applicable in an analogous manner to method 1400 described above with respect to <figref idref="f0149 f0150">Figures 14A-14B</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 1400 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0451In accordance with some embodiments, <figref idref="f0151">Figure 15</figref> shows a functional block diagram of an electronic device 1500 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0151">Figure 15</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

0452As shown in <figref idref="f0151">Figure 15</figref>, an electronic device 1500 includes a display unit 1502 configured to display a messaging user interface on the display unit 1502, the messaging user interface including: a conversation transcript of a messaging session between a user of the electronic device and at least one other user, including a first other user, and a message region in the conversation transcript for a message received from the first other user, the message region including one or more screen elements that conceal the message received from the first other user; a touch-sensitive surface unit 1504 configured to detect contacts; and a processing unit 1506 coupled with the display unit 1502 and the touch-sensitive surface unit 1504. In some embodiments, the processing unit 1506 includes a detecting unit 1508, a display enabling unit 1510, a receiving unit 1512, a revealing unit 1514, a concealing unit 1516, a removing unit 1518, and a deleting unit 1520.

0453The processing unit 1506 is configured to: detect a first input by a contact at a location on the touch-sensitive surface unit 1504 that corresponds to the message region with the concealed message (e.g., with the detecting unit 1508); and, reveal the concealed message in the message region in response to detecting the first input by the contact (e.g., with the revealing unit 1514).

0454In some embodiments, the one or more screen elements that conceal the message are moving particles.

0455In some embodiments, the message region with the concealed message has a message region outline that is distinct from an outline on message regions in the conversation transcript that do not have concealed messages.

0456In some embodiments, the processing unit 1506 is further configured to: in response to detecting the first input by the contact, enable display of an authentication prompt and/or an authentication interface (e.g., with the display enabling unit 1510); receive an authentication input (e.g., with the receiving unit 1512); in accordance with a determination that the authentication input satisfies authentication criteria, reveal the concealed message in the message region (e.g., with the revealing unit 1514); and in accordance with a determination that the authentication input does not satisfy the authentication criteria, keep the message in the message region concealed (e.g., with the concealing unit 1516).

0457In some embodiments, the first input is a drag gesture by the contact at a location that corresponds to the message region with the concealed message.

0458In some embodiments, detecting the first input by the contact includes detecting a drag gesture by the contact at a location that corresponds to the message region with the concealed message, and the processing unit 1506 is further configured to: dynamically remove portions of the one or more screen elements that conceal the message (e.g., with the removing unit 1518), thereby revealing corresponding portions of the message, in accordance with the movement of the contact in the drag gesture.

0459In some embodiments, the electronic device includes one or more sensors configured to detect intensities of contacts on the touch-sensitive surface unit 1504, and the first input is a press input by the contact at a location that corresponds to the message region with the concealed message.

0460In some embodiments, the electronic device includes one or more sensors configured to detect intensities of contacts on the touch-sensitive surface unit 1504, and detecting the first input by the contact includes detecting an increase in intensity of the contact at a location that corresponds to the message region with the concealed message, and the processing unit 1506 is further configured to: dynamically remove portions of the one or more screen elements that conceal the message (e.g., with the removing unit 1518), thereby revealing corresponding portions of the message, in accordance with the increase in intensity of the contact.

0461In some embodiments, the processing unit 1506 is further configured to: after revealing the concealed message in the message region, conceal the message received from the first other user (e.g., with the concealing unit 1516).

0462In some embodiments, the processing unit 1506 is further configured to: after revealing the concealed message in the message region, automatically delete the message received from the first other user from the conversation transcript (e.g., with the deleting unit 1520).

0463The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0464The operations described above with reference to <figref idref="f0149 f0150">Figures 14A-14B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0151">Figure 15</figref>. For example, detection operations 1408, 1412, and 1414 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Triggering enhanced message content

0465<figref idref="f0152 f0154">Figures 16A-16C</figref> are flow diagrams of a process for applying an effect to a messaging user interface when a message includes an enhanced message content trigger, in accordance with some embodiments. More specifically, these figures relate to methods for determining whether a message in a first message region includes an enhanced message content trigger (e.g., a word, phrase, set of emoji, or other content that triggers the effect, or an option selected by the sender). In response to determining that the message includes the enhanced message content trigger, the effect is applied to the messaging user interface. In some embodiments, the effect is applied to at least one message region other than the first message region. In some embodiments, the effect is applied to a chrome of the messaging user interface.

0466One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing this method are shown in <figref idref="f0088 f0093">Figures 5CB-5CG</figref> and <figref idref="f0094 f0109">5CH-5CW</figref>.

0467<figref idref="f0152 f0154">Figures 16A-16C</figref> are flow diagrams illustrating a method 1600, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0468In accordance with some embodiments, method 1600 includes displaying (1602) a messaging user interface (e.g., user interface 5002, as shown in <figref idref="f0068">Figure 5BH</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0092">Figure 5CF</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device) including a first other user. Method 1600 further includes receiving (1604) a first message within the messaging session from an electronic device (e.g., a second electronic device) that corresponds to the first other user included in the messaging session; determining (1606) whether the first message includes an enhanced message content trigger; in accordance with a determination that the first message includes the enhanced message content trigger: displaying (1616) the first message in a first message region in the conversation transcript on the display, and displaying enhanced message content that corresponds to the trigger, wherein the enhanced message content includes content that applies an effect to at least one message region other than the first message region in the conversation transcript (for example as shown in <figref idref="f0092">Figure 5CF</figref>); and, in accordance with a determination that the first message does not include the enhanced message content trigger, displaying (1642) the first message in a first message region in the conversation transcript on the display (i.e., without displaying the enhanced message content that corresponds to the trigger, for example as shown in <figref idref="f0093">Figure 5CG</figref>).

0469In some embodiments, the determination (1606) whether the first message includes the enhanced message content trigger is performed (1608) in response to receiving the first message.

0470In some embodiments, determining (1606) whether the first message includes an enhanced message content trigger includes determining (1610) whether the first message includes predefined text. For example, when the first message includes the words "happy birthday," the device displays enhanced message content that includes balloons, as shown in the sequence of <figref idref="f0097 f0098 f0099 f0100 f0101">Figures 5CK to 5CO</figref>. In some embodiments, determining whether the first message includes an enhanced message content trigger includes analyzing content of the first message to determine whether the first message includes predefined message content, such as a word, phrase, emoticon, emoticon string, emoji, emoji string, sticker, and/or sticker string.

0471In some embodiments, determining (1606) whether the first message includes an enhanced message content trigger includes determining (1612) whether the first message includes an embedded non-displayed value (e.g., as determined by a display option selected by the sender) that indicates the enhanced message content to be displayed . For example, the sender of the first message (the first other user) selects a full screen effect option to apply to the first message, and an embedded non-displayed value that corresponds to the full screen effect option selected by the sender is sent with the first message.

0472In some embodiments, determining (1606) whether the first message includes an enhanced message content trigger includes determining (1614) whether a time at which the first message was received corresponds to a predetermined time frame. For example, when the first message is received at or within a predetermined time after midnight on January 1, the device displays enhanced message content that includes fireworks and/or text that states "Happy New Year!"

0473In some embodiments, the enhanced message content includes (1618) content that applies an effect to the entire displayed conversation transcript. For example, the effect applied to the entire conversation transcript may be the animated display of balloons that move past the entire conversation transcript, the animated display of confetti (e.g., as shown in <figref idref="f0090 f0091 f0092">Figures 5CD through 5CF</figref>) that moves past the entire conversation transcript, or the like.

0474In some embodiments, applying (1616) the effect to at least one message region other than the first message region includes accumulating (1620) animated objects (e.g., virtual confetti) on at least one message region other than the first message region. In some embodiments, animated objects accumulate on user interface objects displayed outside the messaging user interface. In some embodiments, animated objects accumulate on a status bar or other portion of the display that is controlled by the operating system of the device.

0475In some embodiments, applying (1616) the effect to at least one message region other than the first message region includes animating (1622) at least one message region other than the first message region. In some embodiments, movement of the other message regions is triggered by movement of the first message region. In some embodiments, other user interface objects displayed outside the messaging user interface are animated.

0476In some embodiments, applying (1616) the effect to at least one message region other than the first message region includes temporarily fading (1624) message regions other than the first message region without fading the first message region, as shown in <figref idref="f0103">Figure 5CQ</figref> (as compared to the <figref idref="f0102">Figure 5CP</figref>).

0477In some embodiments, applying (1616) the effect to at least one message region other than the first message region includes temporarily ceasing to display (1626) message regions other than the first message region while maintaining display of the first message region.

0478In some embodiments, displaying (1616) the enhanced message content that corresponds to the trigger includes displaying (1628) an image (e.g., an animated image) that temporarily replaces the entire messaging user interface. In some other embodiments, displaying (1616) the enhanced message content that corresponds to the trigger includes displaying (1630) an image (e.g., an animated image) that temporarily replaces the entire messaging user interface, except for the first message region. For example, balloons or confetti would be displayed, replacing the entire messaging user interface, or replacing the entire messaging user interface other than the first message region.

0479In some embodiments, applying (1616) the effect to at least one message region other than the first message region includes temporarily highlighting (1632) the first message region without highlighting message regions other than the first message region. For example, in a "balloons" full screen effect, the first message region would be highlighted while the balloons are displayed, without highlighting (or fading) the other message regions in the displayed conversation transcript.

0480In some embodiments, the enhanced message content includes sound (1634). For example, in some embodiments, the sound is played in coordination with the displayed enhanced message content.

0481In some embodiments, the enhanced message content includes tactile output (1636). For example, the tactile output may be haptic effects output in coordination with the displayed enhanced message content.

0482In some embodiments, displaying (1616) the enhanced message content includes displaying (1638) an animation of the first message region. In some embodiments, when displaying the animation, the first message region disappears and subsequently reappears. In some embodiments, the first message region size and/or first message text size changes during the animation.

0483In some embodiments, displaying (1616) the enhanced message content includes generating and displaying (1640) moving virtual objects in response to scrolling of the conversation transcript. For example, this may be implemented by generating and displaying hearts or sparkles coming off of the first message region as the transcript moves.

0484In some embodiments, method 1600 includes ceasing (1644) to display the enhanced message content that corresponds to the trigger. For example, the ceasing to display the enhanced message content occurs in response to user input, or after the enhanced message content has been displayed for a predetermined period of time.

0485It should be understood that the particular order in which the operations in <figref idref="f0152 f0154">Figures 16A-16C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed.

Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1800) are also applicable in an analogous manner to method 1600 described above with respect to <figref idref="f0152 f0154">Figures 16A-16C</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 1600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0493In some embodiments, the enhanced message content includes content that applies an effect to the entire displayed conversation transcript (e.g., with the applying unit 1714).

0494In some embodiments, applying the effect to at least one message region other than the first message region includes accumulating animated objects on at least one message region other than the first message region (e.g., with the accumulating unit 1716).

0495In some embodiments, applying the effect to at least one message region other than the first message region includes animating at least one message region other than the first message region (e.g., with animating unit 1718).

0496In some embodiments, applying the effect to at least one message region other than the first message region includes temporarily fading message regions other than the first message region without fading the first message region (e.g., with the fading unit 1720).

0497In some embodiments, applying the effect to at least one message region other than the first message region includes temporarily ceasing to display message regions other than the first message region while maintaining display of the first message region (e.g., with the ceasing unit 1722).

0498In some embodiments, displaying the enhanced message content that corresponds to the trigger includes displaying an image that temporarily replaces the entire messaging user interface (e.g., with the display enabling unit 1708).

0499In some embodiments, displaying the enhanced message content that corresponds to the trigger includes displaying an image that temporarily replaces the entire messaging user interface, except for the first message region (e.g., with the display enabling unit 1708).

0500In some embodiments, applying the effect to at least one message region other than the first message region includes temporarily highlighting the first message region without highlighting message regions other than the first message region (e.g., with the highlighting unit 1724).

0505In some embodiments, the processing unit 1706 is further configured to cease to display the enhanced message content that corresponds to the trigger (e.g., with the ceasing unit.

0506The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0507The operations described above with reference to <figref idref="f0152 f0154">Figures 16A-16C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0155">Figure 17</figref>. For example, display operations 1602, 1616, 1618, 1620, 1622, 1624, 1626, 1628, 1630, 1632, 1638, 1640, 1642, and 1644, receiving operation 1604, determining operations 1606, 1608, 1610, 1612, and 1614, audio output operation 1634, and tactile output operation 1636 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Detecting and responding to combinable content in separate messages

0508<figref idref="f0156 f0158">Figures 18A-18C</figref>, described in more detail below, relate generally to methods for detecting combinable content in a messaging user interface. More specifically, these figures relate to methods for displaying content corresponding to a predetermined combination when the detected combinable content form the predetermined combination.

0509One or more examples of an electronic device (e.g., portable multifunction device 100 or device 300) implementing this method are shown in <figref idref="f0110 f0115">Figures 5CX-5DC</figref>.

0510<figref idref="f0156 f0158">Figures 18A-18C</figref> are flow diagrams illustrating a method 1800, performed by an electronic device, sometimes herein called a first electronic device, having one or more processors, memory, a touch-sensitive surface, and a display. In some embodiments, the electronic device includes one or more sensors (e.g., sensors in a touch-screen display or trackpad) configured to detect intensities of contacts on the touch-sensitive surface.

0511In accordance with some embodiments, method 1800 includes displaying (1802) a messaging user interface (e.g., user interface 5002, as shown in <figref idref="f0068">Figure 5BH</figref>, of a messaging application) on the display. The messaging user interface includes a conversation transcript (e.g., conversation transcript 5004 in user interface 5002, <figref idref="f0110">Figure 5CX</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., a user of another electronic device) including a first other user, and a message input area (e.g., message input area 5100, <figref idref="f0110">Figure 5CX</figref>).

0512Method 1800 further includes receiving (1804) a first message (e.g., message 5170, in message region 5008, <figref idref="f0110">Figure 5CX</figref>) within the messaging session from an electronic device (e.g., a second electronic device) that corresponds to the first other user included in the messaging session, wherein the first message includes first combinable content (e.g., an emoticon or an image such as an emoji or a sticker), and in response to receiving the first message, displaying (1812) the first message in a first message region in the conversation transcript on the display (for example, as shown in <figref idref="f0110">Figure 5CX</figref>). In some embodiments, the combinable content includes (1806) an emoticon. In some embodiments, the combinable content includes (1808) an emoji. In some embodiments, the combinable content includes (1810) a sticker.

0513Method 1800 continues with receiving (1814) input of a second message in the message-input area (e.g., second message 5172 in message input area 5100, as shown in <figref idref="f0111">Figure 5CY</figref>), and while the second message is displayed in the message-input area, detecting (1816) an input (e.g., 5174, <figref idref="f0111">Figure 5CY</figref>) to send the second message to the messaging session (e.g., detecting a tap gesture on a send icon, 5118, <figref idref="f0111">Figure 5CY</figref>).

0514Further, method 1800 includes, in response (1818) to detecting the input to send the second message to the messaging session: in accordance with a determination that the second message contains second combinable content, and the second combinable content and the first combinable content are parts (e.g., complementary parts) of a predefined combination, displaying (1820) content that corresponds to the predefined combination in the conversation transcript on the display. For example, the content corresponding to the predefined combination is displayed in a second message region, or an area between message regions having messages from the user of the device and message regions with messages from the at least one other user. In some embodiments, content corresponding to the predefined combination is briefly applied to the entire displayed conversation transcript when the second message is initially displayed in the messaging session.

0515Further, in accordance with a determination that the second message does not contain second combinable content that forms a predefined combination with the first combinable content, displaying (1844) the second message in a second message region in the conversation transcript on the display (i.e., without displaying content that corresponds to a predefined combination).

0516In some embodiments, the determination (1820) that the second combinable content and the first combinable content are parts of a predefined combination is performed (1822) in response to detecting the input (e.g., 5174, <figref idref="f0111">Figure 5CY</figref>) to send the second message to the messaging session (e.g., in response to detecting a tap gesture on a send icon, 5118, <figref idref="f0111">Figure 5CY</figref>).

0517In some embodiments, or in some circumstances, the first combinable content and the second combinable content that are part of a predefined combination are the same content (1824). For example, a first word or emoji for beer in a first message (5170, <figref idref="f0112">Figure 5CZ</figref>) and a second, same word or emoji for beer in a second message (5172, <figref idref="f0112">Figure 5CZ</figref>) result in display of content (e.g., content 5176, <figref idref="f0113">Figure 5DA</figref>) that corresponds to the predefined combination, such as an animation of two beer glasses being clicked together (as shown in <figref idref="f0113">Figure 5DA</figref>) and/or display of the word "Cheers!" (as shown in <figref idref="f0113">Figure 5DA</figref>). In some embodiments, the content that corresponds to the predefined combination is displayed in a portion of the messaging user interface (e.g., messaging user interface 5002) between the first and second messages (e.g., between message regions 5008 for first message 5170 and second message 5172, <figref idref="f0113">Figure 5DA</figref>). In another example, a first fist emoji in the first message and a second fist emoji in the second message result in display of content that corresponds to the predefined combination, such as an animation of two fists bumping together.

0518In some embodiments, or in some circumstances, the first combinable content and the second combinable content that are part of a predefined combination are different content (1826). For example, a word or emoji for lightning and a word or emoji for key result in display of content that corresponds to a predefined combination, such as an emoji or sticker representing electricity, such as a light bulb. In another example, an emoji for an apple and the word or symbol (e.g., "<i>π</i>") for the number pi result in display of content that corresponds to a predefined combination, such as an emoji or sticker for an apple pie. In yet another example, the word "Happy" in a first message and the word "Birthday" in a second message result in a display of balloons in a portion of the messaging user interface between the first message and second message or in the entire messaging user interface, for example as shown in <figref idref="f0088">Figures 5CB</figref>, <figref idref="f0089">5CC</figref> and <figref idref="f0096 f0101">5CJ-5CO</figref>.

0519Optionally, users can define combinations of content that are the aforementioned predefined combinations, and/or they can define the content that corresponds to any such combination. More specifically, in some embodiments, or in some circumstances, respective first combinable content and respective second combinable content that are part of a respective predefined combination are defined (1828) by a user of the electronic device. For example, in some embodiments, the predefined combinations are defined by a user of the device or by users in a messaging session. Similarly, in some embodiments, or in some circumstances, the content that corresponds to the predefined combination is defined by a user of the device (1830). For example, in some embodiments, the content that corresponds to the predefined combination is defined by a user of the device or by users in a messaging session.

0520A variety of content can be included in or used as the content that corresponds to the predefined combination. More specifically, in some embodiments, the content that corresponds to the predefined combination includes animated content (1832), examples of which are balloons or confetti that move through the messaging user interface or a portion of the messaging user interface. In some embodiments, the content that corresponds to the predefined combination includes audio content (1834), such as music, or one or more tones, or recorded or synthesized speech. In some embodiments, the content that corresponds to the predefined combination includes haptic content (1836), such as a vibration or vibration pattern. Thus, in some embodiments, the content that corresponds to the predefined combination includes animated content, audio content and/or haptic content (1838).

0521Further, in some embodiments, the content that corresponds to the predefined combination includes (1840) automatically generated message text. For example, in the above described example, with a first word or emoji for beer in a first message (5170, <figref idref="f0112">Figure 5CZ</figref>) and a second, same word or emoji for beer in a second message (5172, <figref idref="f0112">Figure 5CZ</figref>), the first electronic device automatically generates message text, such as "Cheers!", in a message region.

0522In some embodiments, the content that corresponds to the predefined combination includes (1842) content that is applied to the entire displayed conversation transcript when the second message is initially displayed in the messaging session. For example, content in a "full-screen moment," such as displaying a "fireworks" full screen effect in response to a first message, "Happy," and a second message, "New Year," as shown in <figref idref="f0104 f0106">Figures 5CR-5CT</figref>, or displaying a "balloons" full screen effect in response to a first message, "Happy," and a second message, "Birthday," as shown in <figref idref="f0096 f0101">Figures 5CJ-5CO</figref>.

0523In some embodiments, a predefined combination includes first combinable content, second combinable content, and third combinable content (e.g., three complementary parts). For example, when messages with first combinable content (e.g., a foot) and second combinable content (e.g., an Italian flag) are displayed in a conversation transcript, in response to an input to send a third message, in accordance with a determination that the third message contains third combinable content (e.g., a soccer ball), content that corresponds to the predefined combination is displayed in the conversation transcript on the display.

0524It should be understood that the particular order in which the operations in <figref idref="f0156 f0158">Figures 18A-18C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600) are also applicable in an analogous manner to method 1800 described above with respect to <figref idref="f0156 f0158">Figures 18A-18C</figref>. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 1800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0525In accordance with some embodiments, <figref idref="f0159">Figure 19</figref> shows a functional block diagram of an electronic device 1900 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0159">Figure 19</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0526As shown in <figref idref="f0159">Figure 19</figref>, an electronic device 1900 includes a display unit 1902 configured to display a messaging user interface on the display unit, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, including a first other user, and a message input area; a touch-sensitive surface unit 1904 configured to detect contacts; and a processing unit 1906 coupled to the display unit 1902 and the touch-sensitive surface unit 1904. In some embodiments, the processing unit includes display enabling unit 1908, receiving unit 1910, detecting unit 1912, and applying unit 1914,

0527The processing unit 1906 is configured to: receive a first message within the messaging session from an electronic device that corresponds to the first other user included in the messaging session, where the first message includes first combinable content (e.g., with the receiving unit 1910) and in response to receiving the first message, display the first message in a first message region in the conversation transcript on the display unit 1902 (e.g., with the display enabling unit 1908). Processing unit 1906 is further configured to receive input of a second message in the message-input area (e.g., with the receiving unit 1910). Processing unit 1906 is further configured to, while the second message is displayed in the message-input area, detect an input to send the second message to the messaging session (e.g., with the detecting unit 1912) and, in response to detecting the input to send the second message to the messaging session: in accordance with a determination that the second message contains second combinable content and the second combinable content and the first combinable content are parts of a predefined combination, display content that corresponds to the predefined combination in the conversation transcript on the display unit 1902 (e.g., with the display enabling unit 1908) and, in accordance with a determination that the second message does not contain second combinable content that forms a predefined combination with the first combinable content, display the second message in a second message region in the conversation transcript on the display unit 1902 (e.g., with the display enabling unit 1908).

0528In some embodiments, the determination that the second combinable content and the first combinable content are parts of a predefined combination is performed in response to detecting the input to send the second message to the messaging session (e.g., with the detecting unit 1912).

0529In some embodiments, the combinable content includes an emoticon.

0530In some embodiments, the combinable content includes an emoji.

0531In some embodiments, the combinable content includes a sticker.

0532In some embodiments, the first combinable content and the second combinable content that are part of a predefined combination are the same content.

0533In some embodiments, the first combinable content and the second combinable content that are part of a predefined combination are different content.

0534In some embodiments, respective first combinable content and respective second combinable content that are part of a respective predefined combination are defined by a user of the electronic device 1900.

0535In some embodiments, for a respective predefined combination, the content that corresponds to the predefined combination is defined by a user of the device 1900.

0536In some embodiments, the content that corresponds to the predefined combination includes animated content.

0537In some embodiments, the content that corresponds to the predefined combination includes audio content.

0538In some embodiments, the content that corresponds to the predefined combination includes haptic content.

0539In some embodiments, the content that corresponds to the predefined combination includes animated content, audio content and/or haptic content.

0540In some embodiments, the content that corresponds to the predefined combination includes automatically generated message text.

0541In some embodiments, the content that corresponds to the predefined combination includes content that is applied to the entire displayed conversation transcript when the second message is initially displayed in the messaging session (e.g., with the applying unit 1914).

0542The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0543The operations described above with reference to <figref idref="f0156 f0158">Figures 18A-18C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0159">Figure 19</figref>. For example, displaying operations 1802, 1812, 1822, 1824, 1826, 1828, 1830, 1832, 1834, 1836, 1838, 1840, 1842, and 1844, receiving operations 1804, 1806, 1808, 1810, and 1814, detecting operation 1816, and applying operation 1842 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Presenting synchronized media content

0544<figref idref="f0160 f0175">Figures 20A-20P</figref> illustrate example user interfaces for presenting synchronized media content in a messaging application, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below. Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface 451 that is separate from the display 450, as shown in <figref idref="f0006">Figure 4B</figref>. For convenience of explanation, the embodiments described below will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, a focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch-sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces discussed below, along with a focus selector.

0545As shown in <figref idref="f0160">Figure 20A</figref>, a first user of a first electronic device (e.g., device 100) receives an invitation from a second user of a second electronic device to synchronously watch a media item. As shown in <figref idref="f0160">Figure 20A</figref>, the first user receives a message that is displayed within a messaging user interface (i.e., a user interface that is displayed within a messaging application) that informs the first user that the second user would like to watch a "trailer for movie 123" together. In some embodiments, the first user accepts the invitation by tapping (e.g., tap 2001) within a message region (e.g., the message bubble 2002 shown in <figref idref="f0160">Figure 20A</figref>) that includes the invitation and also optionally includes a representation (e.g., a thumbnail view) of the media item. In some embodiments or circumstances, a message region is a message bubble, platter, or other container for a message in a conversation transcript of a messaging session.

0546As shown in <figref idref="f0161">Figure 20B</figref>, in response to detecting that the first user has accepted the invitation (e.g., detecting the tap gesture 2001 over the representation of the media item), the electronic device 100 provides the user with an animation that indicates that the media item will be displayed at a larger size within the messaging user interface. For example, the representation of the media item increases in size within the message user interface and begins to expand so that at least a portion of the representation is displayed outside of the message region (e.g., the representation of the media item is shown as increasing in size and expanding outside of the message bubble 2002, <figref idref="f0161">Figure 20B</figref>).

0547The animation continues with the representation continuing to increase in size and, as shown in <figref idref="f0162">Figure 20C</figref>, the representation of the media item is eventually shown as occupying a different part of the messaging user interface (e.g., a central region of the messaging user interface). In some embodiments, the initial location of the representation of the media item after the animation completes is referred to as the chronological position of the media item (i.e., the media item is shown in a chronological order relative to other messages that were received either before or after initiation of synchronized viewing of the media item). For example, as shown in <figref idref="f0163">Figure 20D</figref>, the representation of the media item is shown at its chronological position, which is between a position representing a message that was received before initiation of synchronized viewing of the media item (e.g., position for message region 2010) and between a position for a message that was received after initiation of synchronized viewing of the media item (e.g., position for message region 2012). Additionally, chronological positions of the media item and messages received before/ after initiation of synchronized viewing are maintained as new messages are received (as shown in <figref idref="f0164">Figure 20E</figref>, receiving/ displaying a new message moves content in the conversation transcript in a substantially vertical direction while maintaining respective chronological positions for each respective message region). As discussed in more detail below, in some circumstances, the media item also moves to a fixed position at a top portion of the messaging user interface (as shown in <figref idref="f0167">Figure 20H</figref>).

0548In some embodiments, the representation of the media item includes information that indicates that the media item is being viewed in synchrony with other users (e.g., "Synchronized Viewing of Trailer for Movie 123"), includes an affordance that, when selected, causes the messaging application to begin synchronized viewing of the media item (and causes remote devices associated with other users within the messaging session to concurrently begin synchronized viewing as well) (e.g., the play button affordance shown within the representation of the media item), and a play-head and progress bar. In some embodiments, after (and/ or in conjunction with the animation discussed above) the representation of the media item is displayed in the central region, the message region that included the invitation from the second user is no longer displayed and an indication that the first user has accepted the second user's invitation is instead displayed. For example, the indication that the first user has accepted includes a textual description of "You accepted Alex's invitation to watch trailer for Movie 123" (as shown in <figref idref="f0163">Figure 20D</figref>).

0549As shown in <figref idref="f0163">Figure 20D</figref>, the users in the messaging session (e.g., the first and the second user) are able to continue exchanging messages while the representation of the media item is displayed (before and/ or during initiation of playback of the media item). For example, the second user sends a message of "Playing the trailer now!" and that message moves all of the content within the conversation transcript in a substantially vertical (e.g., upward) direction. In this way, users are able to fluidly continue conversing before synchronized playback of the media item begins.

0550In response to receiving a request from any of the users in the messaging session to begin synchronized viewing of the media item (e.g., one of the users hits the play affordance shown with the representation of the media item, <figref idref="f0163">Figure 20D</figref>), the device (or the messaging application) initiates playing of content corresponding to the media item. As shown in <figref idref="f0164">Figure 20E</figref>, playing of content corresponding to the media item begins and users are able to continue exchanging messages during synchronized playback of the media item (e.g., the first user sends a message of "This is cool!" and that message moves the content within the conversation transcript in a substantially vertical direction, while continuing to play the content corresponding to the media item).

0551As shown in <figref idref="f0165 f0166">Figure 20F-20G</figref>, the users are able to continue exchanging messages while the synchronized viewing of the media item continues. In some embodiments, the newly exchanged messages continue to move content in the conversation transcript in a substantially vertical direction (while still maintaining a chronological ordering of each respective message region).

0552As shown in <figref idref="f0167">Figure 20H</figref>, once the representation of the media item is within a predetermined distance of a top portion of the messaging user interface (e.g., 1 px, 2 px, 3 px, 4 px, 5 px, or some other predetermined distance), the representation of the media item is then displayed at a fixed position within the messaging user interface (in other words, the representation of the media item is not displayed at its chronological position). In some embodiments, a representation of the media item does remain at the chronological position and the representation is also displayed at the fixed position (i.e., representations are shown in two places).

0553As shown in <figref idref="f0168">Figure 20I</figref>, while playing content corresponding to the media item and while displaying the representation of the media item at the fixed position, users are able to continue exchanging messages and those messages cause earlier messages to move underneath the playing content corresponding to the media item (in order to avoid obscuring viewing of the playing content). In some embodiments, users are also able to manipulate (e.g., fast-forward, rewind, pause, and the like) the playing content corresponding to the media item and those manipulations are communicated to devices for other users in the messaging session in order to continue synchronized viewing of the media item for all of the users in the messaging session. For example, as shown in <figref idref="f0168">Figure 20I</figref>, the first user is able to drag a play-head (e.g., gesture 2003) to fast-forward the playing content and the fast-forward command is also communicated to devices for other users in the messaging session (techniques for transmitting this information are discussed in detail below in reference to <figref idref="f0176 f0178">Figures 21A-21C</figref>). In some embodiments, the messaging user interface is also updated to indicate that the first user performed a respective manipulation of the playing content (e.g., "You fast-forwarded trailer for movie 123," <figref idref="f0169 f0170">Figures 20J-20K</figref>).

0554As another example of user manipulations of the playing content, after the second user manipulates the playing content by providing a rewind command, the playing content is shown in the messaging user interface at the first electronic device in accordance with the second user's rewind command (e.g., as shown between <figref idref="f0169 f0170">Figures 20J-20K</figref>, the play-head for the playing content has moved backwards due to the second user's rewind command). In some embodiments, the messaging user interface is also updated to indicate that the second user performed a respective manipulation of the playing content (e.g., "Alex rewound trailer for move 123," <figref idref="f0170">Figure 20K</figref>).

0555As is also shown in <figref idref="f0170">Figure 20K</figref>, the first user is able to scroll the conversation transcript while the synchronized viewing of the media item is ongoing. For example, the first user provides gesture 2022 that, when detected, causes the device to scroll the conversation transcript in a substantially downward direction (<figref idref="f0170">Figure 20K</figref>). While scrolling the conversation transcript (and the content included therein), the device determines whether the playing content corresponding to the media item should be moved back to its chronological position (and no longer displayed at the fixed position). In accordance with a determination that the playing content corresponding to the media item should be moved back to its chronological position (e.g., chronological position is scrolled to within a predetermined distance of the fixed position, as discussed below in reference to <figref idref="f0176 f0178">Figures 21A-21C</figref>), the playing content corresponding to the media item is moved to the chronological position and is no longer displayed at the fixed position. As shown in <figref idref="f0171">Figure 20L</figref>, the first user is also able to scroll in a substantially upward direction (e.g., by providing gesture 2024) and, in response, the playing content corresponding to the media item moves back to the fixed position at an appropriate time (e.g., as shown in <figref idref="f0172">Figure 20M</figref> after scrolling in an upward direction, the playing content corresponding to the media item moves back to the fixed position). In this way, users are able to intuitively scroll through the conversation transcript without interrupting their viewing of the media item.

0556As shown in <figref idref="f0173 f0174">Figures 20N-20O</figref>, an end of the playing content corresponding to the media item is detected (e.g., playing of the media item finishes, one of the users exits the messaging application, or one of the users provides a stop command) and, in response, the device provides an animation of the representation of the media item shrinking in size and returning to its chronological position within the conversation transcript (as shown in <figref idref="f0174">Figure 20O</figref> for animation 2050, the representation shrinks in size and beings to move back towards its chronological position, as shown in <figref idref="f0175">Figure 20P</figref>).

0557<figref idref="f0176 f0178">Figures 21A-21C</figref> are flow diagrams illustrating a method 2100 of presenting synchronized media content in a messaging application, in accordance with some embodiments. The method 2100 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 2100 are, optionally, combined and/or the order of some operations is, optionally, changed.

0558As described below, the method 2100 provides an intuitive way to present synchronized media content in a messaging application. The method produces more efficient human-machine interfaces by allowing users to easily view media content in a synchronized fashion directly within a messaging application (and without having to be co-located with another user viewing the media content and without having to use very inefficient techniques to enable synchronized viewing). For battery-operated devices, the method increases user satisfaction with their devices, conserves power (e.g., by requiring few inputs to enable synchronized viewing of media content), and increases the time between battery charges. Furthermore, allowing users to easily view media content in a synchronized fashion directly within a messaging application enhances the operability of the device and makes the user-device interface (e.g., in the messaging application) more efficient (e.g., by allowing for efficient synchronized viewing of media items).

0559As shown in <figref idref="f0176">Figure 21A</figref>, the device displays (2102), on the display, a messaging user interface, the messaging user interface including a conversation transcript of a messaging session between a user of the first electronic device and at least one other user. The conversation transcript includes (2104) a representation of a media item that is displayed at a chronological position within the conversation transcript. For example, the representation of the media item is an icon that shows a still image from the media item (such as a representation shown in <figref idref="f0160">Figure 20A</figref> within message container 2002), or a link to the media item that when selected causes the device to display the icon that shows the still image from the media item (such as a link displayed within the message container 2002 that indicates "click here to being synchronized viewing" or "click here to accept synchronized viewing invitation"). The messaging session is configured (2104) to allow synchronized viewing of the media item by the user at the first electronic device and the at least one other user at a second electronic device that is distinct (and remotely located) from the first electronic device. In some embodiments, the media item is specially configured to allow synchronized viewing. In some embodiments, the messaging session or a messaging application associated with the messaging session (and displaying the messaging user interface) is able to take any media item and allow synchronized viewing of the media item using a variety of synchronized viewing techniques that are discussed in more detail below.

0560In some embodiments, the representation of the media item is added to the conversation transcript by the user (2106). In some embodiments, the representation of the media item is added to the conversation transcript by the at least one other user (2108). In this way, any user in the messaging session is able to initiate synchronized viewing of the media item. Additional details regarding facilitating/ transmitting messages between the user and the at least one other user in order to enable synchronous viewing of the media item are provided below.

0561In some embodiments, the device receives (2110) a first request for synchronized viewing of the media item within the messaging user interface (e.g., the first request is from the user or the at least one other user). In some embodiments, receiving the first request includes receiving a URL for the media item and when a respective user (e.g., the user or the at least one other user or some other user associated with the messaging session) activates a play button for the media item, the device sends a play command, via a messaging network (cellular, WiFi) to the second electronic device and an indication of a current time at the first electronic device. In some embodiments, if the at least one other user hits the play button first, then the first electronic device receives the play command and the indication of a current time at the second electronic device.

0562In response to receiving the first request, the device initiates playing (2110) of content corresponding to the media item while the representation of the media item is displayed at the chronological position within the conversation transcript. In some embodiments, the first request is received (2112) via the second electronic device (e.g., a request by the at least one other user at the second electronic device to synchronously view the media item is routed through a server or sent directly to the first electronic device). In some embodiments, the first request is received (2114) via the user at the first electronic device (e.g., the user selects the play button shown in the representation of the media item illustrated in <figref idref="f0162">Figure 20C</figref>). In some embodiments, playing includes playing the content in a synchronized fashion at both the electronic device and the second electronic device for synchronized viewing by the user and the at least one other user, respectively. In some embodiments, initiation of playback of the content corresponding to the media item is delayed when the user hits play (e.g., by 2 seconds to account for time it takes to send a message to the second electronic device and begin playback at the second electronic device). In other embodiments, sending/ receiving the URL includes sending/ receiving information to push playback on the second device ahead in time (e.g., jump by 1-2 seconds to sync playback on the devices).

0563Turning now to <figref idref="f0177">Figure 21B</figref>, the device (before displaying the playing content corresponding to the media item at the fixed position), displays (2116) messages exchanged between the user and the at least one other user within the messaging user interface, including displaying the messages under the playing content corresponding to the media item (as shown in <figref idref="f0163 f0166">Figures 20D-20G</figref>, exchanged messages are displayed underneath the playing content and a position within the messaging user interface of the playing content corresponding to the media item is moved towards a top portion of the messaging user interface). In other words, displaying the messages includes moving the chronological position of the playing content towards the top portion of the messaging user interface, because as new messages are received and displayed in the messaging user interface, earlier messages continue to move (or be pushed) towards the top portion. In some embodiments, relative vertical positioning of messages with respect to other messages corresponds to an earlier chronological position.

0564In accordance with a determination that the chronological position is within a predetermined distance of the top portion of the messaging user interface, the device displays (2118) the playing content corresponding to the media item at the fixed position within the messaging user interface (e.g., a synchronized content position that is defined relative to the top portion of the messaging user interface, such that the content item is pinned at the top portion of the messaging user interface while exchanged messages appear below). As shown in <figref idref="f0167 f0170">Figures 20H-20K</figref>, messages exchanged between the users continue to be displayed beneath the playing content while it is located at the fixed/ pinned position.

0565After initiating playing of the content corresponding to the media item (and while continuing to play the content corresponding to the media item), the device displays (2120) (e.g., moves) the playing content corresponding to the media item at the fixed position within the messaging user interface that is different than the chronological position. In some embodiments, the content corresponding to the media item (or the representation of the media item) floats up to the fixed position sometime after initiating playback of the content corresponding to the media item. In some embodiments, the representation of the media item remains in the chronological position while the content is playing and messages exchanged between the user and the at least one other user push the chronological position towards a top portion of the messaging user interface. In some embodiments, in accordance with a determination that the content corresponding to the media item has moved to within a predetermined distance of the top portion, the electronic device displays the content corresponding to the media item at the fixed position (as also discussed above). In some embodiments, the representation of the media item is displayed at the chronological position (above the fold) while the playing content corresponding to the media item is displayed at the fixed position (in other words, representations of the media item are displayed at the fixed position and at the chronological position). By displaying the representation of the media item at the fixed position, users are able to continue viewing the media item in a substantially synchronous fashion with other users without having to interrupt their conversation. Therefore, users are able to quickly and conveniently watch a media item together and continue conversing normally, thereby enhancing operability of the device 100 and producing more efficient user-device interfaces (e.g., users need not switch back and forth between a messaging application and some other media-sharing or watching application).

0566In some embodiments, while displaying the playing content corresponding to the media item, users are able to manipulate the playing content (2122) (e.g., fast-forward, rewind, pause) and users are also able to scroll the conversation transcript (2126).

0567With respect to operation 2122, the device receives an indication that the at least one other user has manipulated the playing content (e.g., issued a fast-forward, rewind, or pause command) corresponding to the media item. In response to receiving the indication, the device modifies presentation of the playing content corresponding to the media item at the electronic device in accordance with the manipulations from the at least one other user (e.g., as shown in <figref idref="f0168 f0169">Figures 20I-20J</figref> (fast-forward) and <figref idref="f0169 f0170">Figures 20J-20K</figref> (rewind)). In this way, users are able to continue synchronous viewing of the media item while also being able to manipulate a position of the content corresponding to the media item and other users will seamlessly be provided with those manipulations as well.

0568In some embodiments, the manipulations include one or more of fast-forwarding the playing content, rewinding the playing content, and/or pausing the playing content. For example, the indication indicates that the at least one other user fast-forwarded the playing content and, in response to receiving the indication of the fast-forwarding, the presentation of the playing content is modified in accordance with the fast-forwarding (e.g., both the user's device and another device associated with the at least one other user both display the fast-forwarding in a substantially synchronous fashion). As another example, the indication indicates that the at least one other user rewound the playing content and, in response, the presentation of the playing content is modified in accordance with the rewinding. As one more example, the indication indicates that the at least one other user paused the playing content and, in response, the presentation of the playing content is paused.

0569As to operation 2126, while displaying the playing content corresponding to the media item at the fixed position, the device detects an input (e.g., a drag gesture moving the conversation transcript in a downward direction, as shown for gesture 2022 in <figref idref="f0170">Figure 20K</figref>). In response to detecting the input, the device scrolls the conversation transcript (as shown in <figref idref="f0171">Figure 20L</figref>, the conversation transcript is scrolled in a downward direction in response to the gesture 2022). While scrolling the conversation transcript, in accordance with a determination that the chronological position of the media item is within a predetermined distance of the fixed position (e.g., within 1 px, 2 px, 3 px, 4 px, or 5 px, or some other predefined distance), the device moves the playing content to the chronological position while continuing to play the playing content (as shown in <figref idref="f0171">Figure 20L</figref>, the representation of the media item is now shown at the chronological position in response to the scroll gesture 2022 and is no longer displayed at the fixed position. In this way, if the user scrolls far enough back in the conversation, then the playing content moves back to the chronological position instead of remaining at the fixed position, thus ensuring a smooth viewing experience of the content corresponding to the media item.

0570Turning now to <figref idref="f0178">Figure 21C</figref>, while displaying the playing content corresponding to the media item at the fixed position, the device: displays (2128) messages exchanged between the user and the at least one other user below the playing content corresponding to the media item (and passing behind the playing content corresponding to the media item, so that viewing of the media item is uninterrupted and so that the users are able to continue exchanging messages while synchronously viewing the media item).

0571While displaying the playing content corresponding to the media item at the fixed position, the device also detects (2128) an end of the content corresponding to the media item. In response to detecting the end of the content corresponding to the media item, the device ceases to display the content corresponding to the media item at the fixed position. In some embodiments, ceasing to display includes presenting an animation of the media item (or the representation of the media item) returning to the chronological position within the conversation transcript (e.g., the animation 2050 illustrated in <figref idref="f0173 f0175">Figures 20N-20P</figref>). This animation effect provides users with a visual reminder of the chronological position for the media item, since many messages may have been exchanged and the user may no longer be able to locate the media item (or the representation thereof) within the conversation transcript. Providing this animation effect enhances the operability of the device 100 and makes the user-device interface more efficient (e.g., by ensuring that the user knows where the media is located within the conversation transcript, so that they can easily and efficiently locate the media item at a later point in time).

0572In some embodiments, detecting the end of the playing of the content corresponds (2130) to receiving a request to end playing of the content (e.g., the request is received from any user associated with the messaging session, such as when a user hits a stop button or when a user leaves the messaging application). In some embodiments, detecting the end of the playing of the content corresponds (2132) to reaching an end of the playing of the content (e.g., the playing content concludes after reaching an end point).

0573In some embodiments, the synchronous viewing of the content corresponding to the media item described above is facilitated by sending play-head information over a message channel (e.g., a meta-message) whenever either user (or any user in a messaging session that includes more than two users) manipulates a position of the playing content (as discussed above with respect to fast-forwarding, rewinding, and/or pausing). In some embodiments, time synchronization protocols are used to send messages back and forth whenever the play-head is manipulated and/or to verify that the content is being viewed synchronously (e.g., if a particular user's network connection slows down, this can be detected and used to also slow down viewing at an electronic device for a different user (who is part of the messaging session in which synchronized viewing of a media item is taking place) in order to ensure that viewing remains synchronous). In some embodiments, if a touch event is detected (at an electronic device associated with a user who is part of a messaging session that includes synchronized viewing of a media item) that manipulates the play-head of the media item, the electronic device actively tracks the touch event and keeps sending messages (including play-head information) to the second electronic device (or to a plurality of devices, including the second electronic device) in order to ensure that synchronized viewing continues with interruption.

0574The embodiments and techniques for enabling synchronous viewing of media items in a messaging application may also be applied to asynchronous games that are played within a messaging application (including checkers, chess, connect four, gin, tic-tac-toe, etc.), a shared shopping list (e.g., both users are able to synchronously view a shopping list within a messaging application and can each individually check off items while they are shopping at the same or remotely-located businesses), a shared to-do list, and collaborative drawings.

0575It should be understood that the particular order in which the operations in <figref idref="f0176 f0178">Figures 21A-21C</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 2100 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 2100 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0576In accordance with some embodiments, <figref idref="f0179">Figure 22</figref> shows a functional block diagram of an electronic device 2200 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0179">Figure 22</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0577As shown in <figref idref="f0179">Figure 22</figref>, an electronic device 2200 includes a display unit 2202 configured to display a user interface, a touch-sensitive surface unit 2204 configured to receive contacts, one or more sensor units 2206 for detecting intensities of contacts on the touch-sensitive surface unit 2204; and a processing unit 2208 coupled with the display unit 2202, the touch-sensitive surface unit 2204 and the one or more sensor units 2206. In some embodiments, the processing unit 2208 includes a displaying unit 2210, a synchronized viewing request receiving unit 2212, a play initiation unit 2214, an indication receiving unit 2216, a detecting unit 2218, and/or presentation modification unit 2220, and/or a scrolling unit 2222.

0578The processing unit 2208 is configured to display (e.g., with the displaying unit 2210), on the display (e.g., the display unit 2202), a messaging user interface, the messaging user interface including a conversation transcript of a messaging session between a user of the first electronic device and at least one other user. In some embodiments, the conversation transcript includes a representation of a media item that is displayed at a chronological position within the conversation transcript, and the messaging session is configured to allow synchronized viewing of the media item by the user at the first electronic device and the at least one other user at a second electronic device that is distinct from the first electronic device. The processing unit is also configured to: receive a first request for synchronized viewing of the media item within the messaging user interface (e.g., with the synchronized viewing request receiving unit 2212) and, in response to receiving the first request, initiate playing of content corresponding to the media item (e.g., with the play initiation unit 2214) while the representation of the media item is displayed at the chronological position within the conversation transcript. After initiating playing of the content corresponding to the media item, display the playing content corresponding to the media item at a fixed position (e.g., with the displaying unit 2210 in conjunction with the display unit 2202) within the messaging user interface that is different than the chronological position. While displaying the playing content corresponding to the media item at the fixed position: (i) display (e.g., with the displaying unit 2210 in conjunction with the display unit 2202) messages exchanged between the user and the at least one other user below the playing content corresponding to the media item and (ii) detect an end of the content corresponding to the media item (e.g., with the detecting unit 2218). In response to detecting the end of the content corresponding to the media item, cease to display the content corresponding to the media item at the fixed position (e.g., with the displaying unit 2210 in conjunction with the display unit 2202).

0579In accordance with some embodiments of the electronic device 2200, the processing unit is further configured to: receive an indication that the at least one other user has manipulated the playing content corresponding to the media item (e.g., with the indication receiving unit 2216); and, in response to receiving the indication, modify presentation of the playing content corresponding to the media item at the electronic device in accordance with the manipulations from the at least one other user (e.g., with the presentation modification unit 2220).

0580In accordance with some embodiments of the electronic device 2200, the manipulations include fast-forwarding the playing content, rewinding the playing content, and/or pausing the playing content.

0581In accordance with some embodiments of the electronic device 2200, the representation of the media item is added to the conversation transcript by the user.

0582In accordance with some embodiments of the electronic device 2200, the representation of the media item is added to the conversation transcript by the at least one other user.

0583In accordance with some embodiments of the electronic device 2200, the first request is received via the second electronic device.

0584In accordance with some embodiments of the electronic device 2200, the first request is received via the user at the first electronic device.

0585In accordance with some embodiments of the electronic device 2200, the processing unit is further configured to: before displaying the playing content corresponding to the media item at the fixed position: (i) display (e.g., with the displaying unit 2210 in conjunction with the display unit 2202) messages exchanged between the user and the at least one other user within the messaging user interface, and displaying the messages includes displaying the messages under the playing content corresponding to the media item, such that a position within the messaging user interface of the playing content corresponding to the media item moves towards a top portion of the messaging user interface; and (ii) in accordance with a determination that the chronological position is within a predetermined distance of the top portion of the messaging user interface, display the playing content corresponding to the media item at the fixed position within the messaging user interface.

0586In accordance with some embodiments of the electronic device 2200, the processing unit is further configured to: while displaying the playing content corresponding to the media item at the fixed position, detect an input; in response to detecting the input, scroll the conversation transcript (e.g., with the scrolling unit 2222); and while scrolling the conversation transcript, in accordance with a determination that the chronological position of the media item is within a predetermined distance of the fixed position, move the playing content to the chronological position while continuing to play the playing content (e.g., with the displaying unit in conjunction with the display unit 2202).

0587In accordance with some embodiments of the electronic device 2200, detecting the end of the playing of the content corresponds to receiving a request to end playing of the content.

0588In accordance with some embodiments of the electronic device 2200, detecting the end of the playing of the content corresponds to reaching an end of the playing of the content

0589The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0590The operations described above with reference to <figref idref="f0176 f0178">Figures 21A-21C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0179">Figure 22</figref>. For example, one or more of the operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Incorporate handwritten inputs in messages

0591<figref idref="f0180 f0210">Figures 23A-23AE</figref> illustrate example user interfaces for providing and presenting user-specific handwritten inputs in a messaging application, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below. Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface 451 that is separate from the display 450, as shown in <figref idref="f0006">Figure 4B</figref>. For convenience of explanation, the embodiments described below will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, a focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch-sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces discussed below, along with a focus selector.

0592As shown in <figref idref="f0180">Figure 23A</figref>, the device displays a user interface for a messaging application (also referred to herein as a "messaging user interface") and a user of the device is able to activate handwriting features by providing either or both of gestures 2302A and 2302B. In some embodiments, in response to the gestures 2302A and/or 2302B and while the device is in a portrait orientation, the device displays selectable representations of handwritten inputs (as shown in <figref idref="f0181">Figure 23B</figref> for user interface region 2351).

0593In some embodiments, in response to receiving a selection of one of the selectable representations shown in user interface region 2351 (e.g., in response to input 2304 over a first selectable representation), the device updates message-input region 2303 to include handwritten text that is associated with the first selectable representation (e.g., as shown in <figref idref="f0181">Figure 23B</figref>, the message-input area is updated to include handwritten text of "Thank you").

0594In some embodiments, users are also able to select handwritten text that is displayed in the message-input area 2303. For example, in response to a tap over the handwritten text displayed in the message-input area 2303 (<figref idref="f0181">Figure 23B</figref>), the device may allow the user to then edit that handwritten text (e.g., by displaying a user interface such as that shown in <figref idref="f0189">Figure 23J</figref> that allows for editing handwritten text).

0595As shown in <figref idref="f0182">Figure 23C</figref>, in some embodiments, the device also provides suggestions to auto-replace typed text with handwritten text.

0596In addition to selecting handwritten text by selecting any of the selectable representations shown in user interface region 2351, some embodiments also allow users to simply rotate the device in order to provide new handwritten inputs. For example, the user simply rotates the device from the portrait orientation (<figref idref="f0183">Figure 23D</figref>) to a landscape orientation (<figref idref="f0184">Figure 23E</figref>) and, in response to detecting this orientation change, the device displays a user interface that is configured to accept handwritten inputs from the user (e.g., user interface 2309, <figref idref="f0184">Figure 23E</figref>).

0597In some embodiments, users may select background colors and/or patterns for the handwritten inputs (e.g., in response to user input 2308, <figref idref="f0184">Figure 23E</figref>, the device displays a background selection user interface, <figref idref="f0185">Figure 23F</figref>). In response to a selection (e.g., tap 2310, <figref idref="f0185">Figure 23F</figref>), the device modifies a background for the user interface 2309 accordingly (as shown in <figref idref="f0186">Figure 23G</figref>).

0598<figref idref="f0187 f0189">Figures 23H-23J</figref> illustrate that the user is able to provide the handwritten inputs at the user interface 2309 and, as the user is providing the handwritten inputs, the device presents a real-time preview 2312 of those handwritten inputs. The device may also allow the user to provide a label for a newly-provided handwritten input. For example, in response to a selection of "Label" shown in the upper left corner of <figref idref="f0189">Figure 23J</figref>, the device displays a user interface that allows the user to provide a label.

0599In some embodiments, the user is able to type the label into input region 2314 (as shown in <figref idref="f0190 f0191">Figures 23K-23L</figref>). In some embodiments, the input region 2314 is auto-populated with a suggested label (e.g., by applying an optical character recognition algorithm to the newly provided handwritten inputs the device is able to suggest an appropriate label). In response to user selection (e.g., tap 2316, <figref idref="f0191">Figure 23L</figref>) of a "Save" affordance, the device saves the label and associates the newly-provided handwritten input (e.g., handwritten strokes for the newly-provided "Thank you" text) therewith. As shown in <figref idref="f0192">Figure 23M</figref>, the device also provides an indication that the newly-provided handwritten input is associated with the label (e.g., indication 2318).

0600In some embodiments, in response to selection of a "Done" link (e.g., tap 2320) the device adds the newly-provided handwritten input to the message input-area 2303 and the user is then able to send the newly-provided handwritten input to other users. For example, as shown in <figref idref="f0193 f0201">Figures 23N-23V</figref>, after the user sends the newly-provided handwritten input, devices associated with the other users are instructed to render the handwritten input at a predetermined pace (e.g., a second electronic device 2360 presents an indication that the user is provided a handwritten input (e.g., indication 2322) and then the second device 2360 presents an animation of the handwritten input being drawn at the predetermined pace (as shown in <figref idref="f0196 f0201">Figures 23Q-23V</figref> for animation 2324)).

0601In some embodiments, line thickness for a particular handwritten stroke (e.g., strokes provided in conjunction with a particular handwritten input) is determined based on velocity and force applied by a user's finger (or stylus) during the particular handwritten stroke. In some embodiments, a number of ink-rendering techniques are utilized in order to accurately mimic the way that ink naturally swells on a surface (as discussed in more detail below).

0602In some embodiments, users are also able to train a custom user-specific handwriting keyboard via the user interfaces shown in <figref idref="f0202 f0207">Figures 23W-23AB</figref>. In some embodiments, after successfully training the handwriting keyboard, the device is able to present the custom user-specific handwriting keyboard (as shown in <figref idref="f0208">Figure 23AC</figref>).

0603As shown in <figref idref="f0210">Figure 23AE</figref>, in some embodiments, in addition to providing handwritten text, users are also able to provide handwritten drawings (or a combination of handwritten text and handwritten drawings). Any of the techniques discussed herein with respect to handwritten text are also applicable to handwritten drawings (such as the goldfish sketch shown in <figref idref="f0210">Figure 23AE</figref>).

0604As shown in <figref idref="f0209 f0210">Figures 23AD-23AE</figref>, in some embodiments, the user interfaces for providing and presenting handwritten inputs are different depending on certain physical characteristics of a display that is in communication with the electronic device (also discussed above). In some embodiments, <figref idref="f0209 f0210">Figure 23AD-23AE</figref> represent user interfaces shown on a device that is in communication with a display of approximately 9.4 inches (about 240 mm), such as an iPad Air (or a device with a larger display, such as an iPad Pro) from Apple Inc. of Cupertino, CA. In order to utilize these larger display sizes, the handwriting input area is displayed at the same time as the conversation transcript (upper right corner) and a listing of current conversations that the user is part of (upper left corner). In some embodiments, any of the details provided herein in reference to handwriting input area 2309 are applicable to the handwriting input area shown in <figref idref="f0209 f0210">Figures 23AD-23AE</figref>.

0605<figref idref="f0211 f0213">Figures 24A-24C</figref> are flow diagrams illustrating a method 2400 of providing and presenting user-specific handwritten inputs in a messaging application, in accordance with some embodiments. The method 2400 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 2400 are, optionally, combined and/or the order of some operations is, optionally, changed.

0606As described below, the method 2400 provides an intuitive way to provide and present user-specific handwritten inputs in a messaging application. The method helps to improve user satisfaction with their devices and produces more efficient human-machine interfaces by allowing users, e.g., to simply rotate their device in order to begin entering handwritten inputs. Such methods and interfaces also produce more efficient human-machine interfaces by allowing to easily, efficiently, and quickly select handwritten inputs for inclusion in a conversation transcript of a messaging application. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. Furthermore, allowing users to simply rotate their devices in order to begin entering handwritten inputs and allowing users to easily, efficiently, and quickly select handwritten inputs enhances the operability of the devices and makes user-device interfaces (e.g., in the messaging application) more efficient (e.g., by allowing users to easily customize their message content with handwritten inputs) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently (e.g., the user need not leave the messaging application, open and use a different application to input or locate handwritten inputs, and then return to use those inputs in the messaging application, instead the user simple provides and/or selects custom handwritten inputs directly within the messaging application).

0607As shown in <figref idref="f0211">Figure 24A</figref>, while the electronic device is in a portrait orientation, the device displays (2402, on the display, a messaging user interface (e.g., a messaging user interface that includes a conversation transcript of a messaging session between a user of the electronic device and at least one other user), the messaging user interface including a virtual keyboard. An example messaging user interface is shown in <figref idref="f0180">Figure 23A</figref>. In some embodiments, the virtual keyboard is not configured to accept handwritten input. In some embodiments, the keyboard is a QWERTY, emoji, or other type of virtual keyboard that does not accept handwritten input (such as the QWERTY keyboard shown in <figref idref="f0180">Figure 23A</figref>.

0608The device detects (2404) a change in the orientation of the electronic device from the portrait orientation to a landscape orientation (e.g., a user of the device physically rotates the device approximately 90 degrees along an axis). As an example, in <figref idref="f0183">Figure 23D</figref>, the device 100 is oriented in the portrait orientation and, in <figref idref="f0184">Figure 23E</figref>, the device is oriented in a landscape orientation.

0609In response to detecting the change in the orientation of the electronic device (e.g., between <figref idref="f0180">Figures 23A</figref> and <figref idref="f0184">23E</figref>, and also between <figref idref="f0183">Figures 23D</figref> and <figref idref="f0184">23E</figref>), the device ceases to display (2406) the virtual keyboard and displays, on the display, a handwriting input area (e.g., area 2309, <figref idref="f0184">Figure 23E</figref>) that is configured to accept handwritten input from a user of the electronic device. As shown in <figref idref="f0183 f0184">Figures 23D-23E</figref>, upon detecting the change in orientation from portrait to landscape, the device displays the handwriting input area 2309 and no longer displays the messaging user interface. In some embodiments, the handwriting input area is displayed in accordance with a determination that the user previously selected a handwriting input affordance (e.g., the user selects the affordance in order to ensure that when the device is oriented in landscape, the handwriting input area will be immediately displayed without requiring the user to manually choose to display the handwriting input area). In this way, by simply rotating the device 100, the user is able to enter a handwriting input mode and begin providing handwritten inputs, thus, producing an efficient human-machine interface for providing handwritten inputs in a messaging application.

0610In some embodiments, ceasing to display the virtual keyboard includes (2408) ceasing to display a conversation transcript that is included in the messaging user interface while the orientation of the electronic device is in the portrait orientation (as shown between <figref idref="f0180">Figures 23A</figref> and <figref idref="f0184">23E</figref> and between <figref idref="f0183">Figures 23D</figref> and <figref idref="f0184">23E</figref>, after the device is rotated to the landscape orientation, the conversation transcript is no longer displayed). In this way, by displaying only the handwriting input area 2309 (i.e., the handwriting input area 2309 occupies substantially all of the display 112) and ceasing to display the conversation transcript, the user is presented with a large canvas on which to provide handwritten inputs. Presenting a large canvas on which to provide handwritten inputs enhances the operability of the device 100 and makes the user-device interface more efficient (e.g., by providing the user with sufficient space to accurately provide handwritten inputs).

0611After displaying the handwriting input area 2309, users are able to provide handwriting inputs (as discussed in reference to operations 2410-2416, <figref idref="f0212">Figure 24B</figref>) and users are able to select representations pre-recorded handwritten inputs (as discussed in reference to operations 2418-2426). Users may perform these operations in any order (e.g., provide handwritten inputs and then later select representations, or vice versa, and may repeat these operations as needed to produce desired handwritten text). In this way, users are able to easily and efficiently provide new handwritten inputs, provide typed inputs, and/or select pre-recorded handwritten inputs in order to produce varied messages to add to a conversation transcript in a messaging application.

0612Turning now to <figref idref="f0212">Figure 24B</figref>, in some embodiments, the device receives (2410 handwritten inputs at the handwriting input area (e.g., the user begins to handwrite "Thank y" as shown in <figref idref="f0187">Figure 23H</figref>). In some embodiments, in response to receiving the handwritten inputs, the device displays a (real-time/ constantly updating) preview (e.g., preview 2312, <figref idref="f0187">Figure 23H</figref>) of the handwritten inputs, the preview including a user interface object (message region/ bubble) in which the handwritten inputs will be displayed within the messaging user interface. As shown in <figref idref="f0187 f0189">Figures 23H-23J</figref>, the preview of the handwritten inputs is shown in the upper right corner in a message bubble that will be used to display the handwritten inputs within the messaging user interface (e.g., after selecting and sending the handwritten inputs to another user, the handwritten inputs are shown within a messaging bubble in the messaging user interface). In some embodiments, handwritten inputs are not shown within message bubbles and are instead displayed as free-standing text within the messaging user interface. One example of a handwritten input within a messaging bubble is shown in <figref idref="f0181">Figure 23B</figref> (e.g., message bubble 2305) and an example of a handwritten input outside of a messaging bubble is shown in <figref idref="f0181">Figure 23B</figref> (e.g., message bubble 2307). By providing a live, real-time preview of the handwritten inputs, operability of the device 100 is enhanced and more efficient user-device interfaces are produced (e.g., by helping the user to provide proper inputs and reduce user mistakes when providing handwritten inputs).

0613In some embodiments, while receiving handwritten inputs in the handwriting input area, the device sends (2412) (e.g., to a server for routing to a second device of a second user who is in a messaging session with the user of the electronic device, or directly to the second device) instructions to display an indication that the user is currently handwriting a message (e.g., a message bubble with a simulated handwritten stroke and the message bubble is displayed within a conversation transcription of a messaging user interface at the second device, such as indication 2322 <figref idref="f0193 f0195">Figures 23N-23P</figref>). In some embodiments, the indication (e.g., 2322, <figref idref="f0193 f0195">Figures 23N-23P</figref>) that that user is currently handwriting a message is different than an indication that is provided when a user is typing a message using an input mechanism other than the handwriting input area (e.g., a virtual QWERTY keyboard).

0614In some embodiments, while receiving handwritten inputs in the handwriting input area, the device determines (2414) that the handwritten inputs are within a predetermined distance of an edge of the handwriting input area (e.g., within 1 px, 2 px, 3 px, 4 px, 5 px, or some other predefined distance) and, in accordance with the determining, while continuing to display at least a portion of the handwritten inputs, the device shifts a displayed portion of the handwriting input area to reveal additional space within the handwriting input area. For example, as shown in <figref idref="f0187 f0189">Figures 23H-23J</figref>, once the handwritten inputs approach within the predetermined distance of the edge, the handwriting input area is shifted to reveal additional space and to allow the user to continue fluidly providing the handwritten inputs. In some embodiments, by continuing to display at least a portion of the handwritten inputs, the user is still able to view some of the previously entered handwritten strokes in order to provide context as the user continues to provide additional handwritten inputs. By dynamically shifting a displayed region of the handwriting input area, operability of the device 100 is enhanced and more efficient user-device interfaces are provided (e.g., by shifting the displayed region, users are able to continue providing handwritten inputs in an uninterrupted fashion, while still being able to view a portion of previously providing handwriting strokes).

0615In some embodiments, the user is able to manually cause the device to shift the displayed portion of the handwriting input area (e.g., by selecting the ">" affordance shown in <figref idref="f0187 f0189">Figures 23H-23J</figref>). In some embodiments, the user is able to provide a two finger swipe gesture in a substantially horizontal direction in order to cause the device to shift the displayed portion of the handwriting input area as well (in order to allow the user to easily navigate to the left or right of a particular handwritten input that is currently displayed on the user interface 2309).

0616In some embodiments, the device receives (2416) a modification to at least a portion of the handwritten inputs (e.g., an annotation or embellishment of some previously-completed handwriting strokes, or a request to undo a portion of the handwritten inputs.) and, in response to receiving the modification, the device modifies the portion of the handwritten inputs and the preview (e.g., 2312) in accordance with the modification. For example, in response to an undo request (e.g., the user clicks an undo button (not pictured) displayed proximate to or within the handwriting input area 2309), the device deletes a last handwritten stroke provided by the user and concurrently deletes the same stroke from the preview 2312. In some embodiments, if the user taps over the undo button and keeps in contact with the undo button for a predetermined period of time (e.g., 2 seconds or more), the device clears the entire handwriting canvas (e.g., user interface/ canvas 2309).

0617Turning now to <figref idref="f0213">Figure 24C</figref>, the device displays (2418), within (or near/next to) the handwriting input area, representations of pre-recorded handwritten inputs from the user of the electronic device. In some embodiments, the pre-recorded handwritten inputs are displayed below the handwritten input area (e.g., as shown in <figref idref="f0189">Figure 23J</figref>, representations are shown for "my bad," "Happy Birthday", and "CONGRATS!!!") and each one is available for selection by the user. In some embodiments, after selecting a first of the pre-recorded handwritten inputs, the handwritten input area is updated to include the first pre-recorded handwritten input and the user is then able to modify the input or include it in the conversation transcript for sending to other users. In some embodiments, in addition to representations of pre-recorded handwritten inputs, the device also displays representations of default pre-stored handwritten inputs.

0618In some embodiments, in addition to being able to modify pre-recorded handwritten inputs, users are also able to select them for sending to other users (e.g., as shown in <figref idref="f0181">Figure 23B</figref>, input 2304 is provided for selecting a representation of the handwritten input "Thank you"). In some embodiments, the device receives (2420) a selection of a first pre-recorded handwritten input (e.g., input 2304, <figref idref="f0181">Figure 23B</figref>) and sends (2422) the first pre-recorded handwritten input (or a representation thereof, or instructions for re-producing the first pre-recorded handwritten input) to a second device that is associated with another user in the messaging session, and sending the first pre-recorded handwritten input to the second device includes instructing the second device to draw the first pre-recorded handwritten input at a predetermined pace at the second device.

0619For example, as shown in <figref idref="f0196 f0201">Figures 23Q-23V</figref> for region 2324 of a messaging application on a second electronic device 2360, in response to user selection of a representation of a first pre-recorded handwritten input of "Thank you," a second device 2360 receives instructions to draw the first pre-recorded handwritten input at the predetermined pace. Additional details are provided below regarding ink-regarding techniques utilized to accurately simulate drawing on of the pre-recorded handwritten input.

0620In some embodiments, instead of drawing the first pre-recorded handwritten input, the second electronic device 2360 just displays (2426) the first pre-recorded handwritten input (i.e., without the drawing discussed above). For example, the second device 2360 just displays the message region 2324 as shown in <figref idref="f0198">Figure 23S</figref>, instead of rendering the drawing effects. Stated another way, in some embodiments, the first pre-recorded handwritten input is added to the messaging user interface at the second device 2360 and is displayed without an animation effect (e.g., without drawing the handwritten input at the predetermined pace).

0621In some embodiments, the predetermined pace corresponds (2424) to a writing pace that was used by the user while providing the first pre-recorded handwritten input. In some embodiments, the predetermined pace corresponds to a writing pace that is different than a pace that was used by the user while providing the first pre-recorded handwritten input (e.g., a default pace for presenting handwritten inputs).

0622In some embodiments, the handwriting input area is available while the device is in the portrait orientation (e.g., for devices with larger displays). In some embodiments, in order to access the handwriting input area while the device is in the portrait orientation, a handwritten input selection affordance is included in the messaging user interface (e.g., affordance shown as being selected by input 2302A, <figref idref="f0180">Figure 23A</figref>, or the affordance shown as being selected by input 2302B, <figref idref="f0180">Figure 23A</figref>). In response to detecting selection of the handwritten input selection affordance, the device ceases to display the virtual keyboard and displays the handwriting input area and representations of pre-recorded handwritten inputs from the user of the electronic device. In some embodiments, the handwritten input selection affordance is only available while in the portrait orientation if the device has a touch-sensitive display that is above a predefined size (e.g., a touch-sensitive display that is at least 7.9 inches, such as those available on iPad and iPad mini devices from APPLE of Cupertino, CA) or a touch-sensitive display that has a resolution that is above a predefined threshold (such as 2048x1536 pixels at 346 ppi, or better, such as those available on the aforementioned devices from APPLE). Stated another way, in some embodiments, smaller smart phones do not have a handwritten input selection affordance displayed at all while the orientation of the smaller device is the portrait orientation and, therefore, the handwritten input area is only available while these smaller devices are oriented in the landscape orientation.

0623It should be understood that the particular order in which the operations in <figref idref="f0211 f0213">Figures 24A-24C</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 2400 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 2400 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0624In some embodiments, the method 2400 described above in reference to <figref idref="f0211 f0213">Figures 24A-24C</figref> utilizes one or more of the techniques described below to render ink on the display in order to accurately simulate the way that ink is applied to a surface.

0625In accordance with some embodiments, <figref idref="f0214">Figure 25</figref> shows a functional block diagram of an electronic device 2500 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0214">Figure 25</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0626As shown in <figref idref="f0214">Figure 25</figref>, an electronic device 2500 includes a display unit 2502 configured to display a user interface, a touch-sensitive surface unit 2504 configured to receive contacts, one or more sensor units 2506 for detecting intensities of contacts on the touch-sensitive surface unit 2504; and a processing unit 2508 coupled with the display unit 2502, the touch-sensitive surface unit 2504 and the one or more sensor units 2506. In some embodiments, the processing unit 2508 includes a displaying unit 2510, a device orientation detecting unit 2512, a handwriting modification unit 2514, a sending unit 2516, a handwritten input selection unit 2518, a determining unit 2520, and/or a handwritten input area shifting unit 2524.

0627The processing unit 2508 is configured to while the electronic device is in a portrait orientation, display (e.g., with the displaying unit 2510), on the display (e.g., the display unit 2502), a messaging user interface, the messaging user interface including a virtual keyboard; detect a change in the orientation of the electronic device from the portrait orientation to a landscape orientation (e.g., with the device orientation detecting unit 2512); and, in response to detecting the change in the orientation of the electronic device: cease to display the virtual keyboard (e.g., with the displaying unit 2510); and display, on the display, a handwriting input area that is configured to accept handwritten input from a user of the electronic device (e.g., with the displaying unit 2510).

0628In accordance with some embodiments of the electronic device 2500, the processing unit is configured to: receive handwritten inputs at the handwriting input area (e.g., with the handwritten modification unit 2514); and in response to receiving the handwritten inputs, display a preview of the handwritten inputs, the preview including a user interface object in which the handwritten inputs will be displayed within the messaging user interface (e.g., with the displaying unit 2510).

0629In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: receive a modification to at least a portion of the handwritten inputs (e.g., with the handwritten modification unit 2514) and, in response to receiving the modification, modify the portion of the handwritten inputs and the preview in accordance with the modification (e.g., with the handwritten modification unit 2514).

0630In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: while receiving handwritten inputs in the handwriting input area, send instructions to display an indication that the user is currently handwriting a message (e.g., with the sending unit 2516).

0631In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: display, within the handwriting input area, representations of pre-recorded handwritten inputs from the user of the electronic device (e.g., with the displaying unit 2510).

0632In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: receive a selection of a first pre-recorded handwritten input (e.g., with the handwritten input selection unit 2518); and send the first pre-recorded handwritten input to a second device that is associated with another user in the messaging session (e.g., with the sending unit 2516), and sending the first pre-recorded handwritten input to the second device includes instructing the second device to draw the first pre-recorded handwritten input at a predetermined pace at the second device.

0633In accordance with some embodiments of the electronic device 2500, the predetermined pace corresponds to a writing pace that was used by the user while providing the first pre-recorded handwritten input.

0634In accordance with some embodiments of the electronic device 2500, the predetermined pace corresponds to a writing pace that is different than a pace that was used by the user while providing the first pre-recorded handwritten input.

0635In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: receive a selection of a first pre-recorded handwritten input (e.g., with the handwritten input selection unit 2518); and send the first pre-recorded handwritten input to a second device that is associated with another user in the messaging session (e.g., with the sending unit 2516), and sending the first pre-recorded handwritten input to the second device includes instructing the second device to display the first pre-recorded handwritten input at the second device.

0636In accordance with some embodiments of the electronic device 2500, the processing unit is further configured to: while receiving handwritten inputs in the handwriting input area, determine that the handwriting inputs are within a predetermined distance of an edge of the handwriting input area (e.g., with the determining unit 2522) and, in accordance with the determining, while continuing to display at least a portion of the handwritten inputs, shift a displayed portion of the handwriting input area to reveal additional space within the handwriting input area (e.g., with the handwritten input area shifting unit 2524).

0637In accordance with some embodiments of the electronic device 2500, ceasing to display the virtual keyboard includes ceasing to display a conversation transcript that is included in the messaging user interface while the orientation of the electronic device is in the portrait orientation.

0638The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0639The operations described above with reference to <figref idref="f0211 f0213">Figures 24A-24C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0214">Figure 25</figref>. For example, some operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0640<figref idref="f0215 f0216">Figures 26A-26B</figref> are flow diagrams illustrating a method 2600 of providing and presenting user-specific handwritten inputs in a messaging application, in accordance with some embodiments. The method 2600 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 2600 are, optionally, combined and/or the order of some operations is, optionally, changed.

0641As described below, the method 2600 provides an intuitive way to provide and present user-specific handwritten inputs in a messaging application. The method helps to improve user satisfaction with their devices and produces more efficient human-machine interfaces by allowing users, e.g., to efficiently auto-replace typed inputs with handwritten inputs. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges (e.g., by requiring only a single input to auto-replace a particular sequence of typed inputs with an associated handwritten input).

0642The device displays (2602), on the display: a messaging user interface, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user (e.g., including the message regions displaying messages exchanged between the user and the at least one other user, as shown in <figref idref="f0180">Figure 23A</figref>), a virtual keyboard (e.g., the virtual QWERTY keyboard shown in <figref idref="f0180">Figure 23A</figref>), and a message-input area (e.g., message-input area 2303, <figref idref="f0181">Figure 23B</figref>).

0643The device also receives (2604), at the virtual keyboard, a plurality of typing inputs (the user types a plurality of keys on the display virtual QWERTY keyboard). For example, as shown in <figref idref="f0182">Figure 23C</figref> (showing close-ups of the message-input area 2303) the user types (in other words, the plurality of typing inputs include the following inputs) "Thank you for helping to play all of this! I think he is going to be really surprised!" While receiving the plurality of typing inputs, the device determines whether one or more typing inputs of the plurality of typing inputs match a stored sequence of characters that is associated with stored handwritten input from the user. In some embodiments, the stored sequence of characters corresponds (2608) to a label that the user provided for the stored handwritten input. For example, the user inputs a variety of handwritten inputs and associates a label with each respective handwritten input (e.g., as shown in <figref idref="f0215 f0216">Figure 23K-23M</figref>, the user associates a label of thank you with recently-typed handwritten text for "Thank you").

0644In accordance with a determination that the one or more typing inputs match the stored sequence of characters (e.g., that the typed inputs "Thank you" match the stored label of "Thank you"), the device displays (2610) at a first location, proximate to a first set of characters that is displayed within the message-input area, a selectable representation of the stored handwritten input (e.g., selectable representation 2392A and 2392B shown in <figref idref="f0182">Figure 23C</figref>), and the first set of characters is displayed within the message-input area and includes characters that correspond to the one or more typing inputs that match the stored sequence of characters.

0645The device also detects (2612), via the touch-sensitive surface, a selection of the selectable representation of the stored handwritten input (e.g., detects one of the inputs 2306 shown in <figref idref="f0182">Figure 23C</figref>). In response to detecting the selection of the selectable representation of the stored handwritten input, the device: ceases to display the selectable representation of the stored handwritten input at the first location and replaces display, within the message-input area, of the first set of characters that correspond to the one or more typing inputs with display of a representation of the stored handwritten input. For example, as shown in <figref idref="f0182">Figure 23C</figref>, in response to input 2306, the device ceases to display the selectable representations 2392A/ 2392B and instead replaces the typed characters "Thank you" with a representation of the stored handwritten input that was displayed in the selectable representation. In this way, the user is able to provide a single input (just a selection of the selectable representation) in order to auto-replace typed text with handwritten text, thereby enhancing operability of the device 100 and making the user-device interface more efficient.

0646Turning now to <figref idref="f0216">Figure 26B</figref>, in some embodiments, after replacing the first set of characters with the representation of the stored handwritten input, the message-input area (e.g., area 2303) includes (2614) both the representation of the stored handwritten input and at least a first typed input of the plurality of typed inputs. (In other words, the user's message includes both handwritten and typed text (as is shown in <figref idref="f0182">Figure 23C</figref>). In this way, the user is able to personalize particular phrases within a single message without having to send handwritten text for the full contents of that single message, thereby enhancing operability of the device 100 and making the user-device interface more efficient.

0647In some embodiments, the device receives (2616) a request to send a message to the at least one other user and, in response to receiving the request, the device displays within the conversation transcript a user interface object that includes an animation that draws the stored handwritten input at a predetermined pace (as shown in <figref idref="f0196 f0201">Figures 23Q-23V</figref> for a second electronic device 2360 and, in some embodiments, the same animation is drawn at the predetermined pace at the device 100). In some embodiments, in response to receiving the request to send the message to the at least one other user, the device sends (through a server or directly to a second device 2360 that is associated with the at least one other user) instructions to render a user interface object that includes the animation that draws the stored handwritten input at the predetermined pace (as shown in <figref idref="f0196 f0201">Figures 23Q-23V</figref>).

0648In some embodiments, the predetermined pace corresponds to a writing pace that was used by the user while providing the stored handwritten input (thus allowing users to provided highly customized handwritten messages that include both the user's handwritten text and the predetermined pace at which the user's handwritten text was previously written). In some embodiments, the predetermined pace corresponds to a writing pace that is different from a pace that was used by the user while providing the stored handwritten input.

0649It should be understood that the particular order in which the operations in <figref idref="f0215 f0216">Figures 26A-26B</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 2600 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 2600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0650In some embodiments, the method 2600 described above in reference to <figref idref="f0215 f0216">Figures 26A-26B</figref> utilizes one or more of the techniques described below to render ink on the display in order to accurately simulate the way that ink is applied to a surface.

0651In accordance with some embodiments, <figref idref="f0217">Figure 27</figref> shows a functional block diagram of an electronic device 2700 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0217">Figure 27</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0652As shown in <figref idref="f0217">Figure 27</figref>, an electronic device 2700 includes a display unit 2702 configured to display a user interface, a touch-sensitive surface unit 2704 configured to receive contacts, one or more sensor units 2706 for detecting intensities of contacts on the touch-sensitive surface unit 2704; and a processing unit 2708 coupled with the display unit 2702, the touch-sensitive surface unit 2704 and the one or more sensor units 2706. In some embodiments, the processing unit 2708 includes a displaying unit 2710, a typing inputs receiving unit 2712, a determining unit 2714, a detecting unit 2716, a replacing unit 2718, a second unit 2720, and a request receiving unit 2722.

0653The processing unit 2708 is configured to display, on the display (e.g., with the displaying unit 2710 in conjunction with the display unit 2702), a messaging user interface, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, a virtual keyboard, and a message-input area; receive, at the virtual keyboard, a plurality of typing inputs (e.g., with the typing inputs receiving unit 2712); while receiving the plurality of typing inputs, determine whether one or more typing inputs of the plurality of typing inputs match a stored sequence of characters that is associated with stored handwritten input from the user (e.g., with the determining unit 2714); in accordance with a determination that the one or more typing inputs match the stored sequence of characters, display (e.g., with the displaying unit 2710) at a first location, proximate to a first set of characters that is displayed within the message-input area, a selectable representation of the stored handwritten input, and the first set of characters is displayed within the message-input area and includes characters that correspond to the one or more typing inputs that match the stored sequence of characters; detect (e.g., with the detecting unit 2716)), via the touch-sensitive surface, a selection of the selectable representation of the stored handwritten input; and, in response to detecting the selection of the selectable representation of the stored handwritten input: cease to display (e.g., with the displaying unit 2710) the selectable representation of the stored handwritten input at the first location; and replace display (e.g., with the replacing unit 2718), within the message-input area, of the first set of characters that correspond to the one or more typing inputs with display of a representation of the stored handwritten input.

0654In accordance with some embodiments of the electronic device 2700, the processing unit is configured to: receive a request (e.g., with the request receiving unit 2722) to send a message to the at least one other user; and, in response to receiving the request, display (e.g., with the displaying unit 2710) within the conversation transcript a user interface object that includes an animation that draws the stored handwritten input at a predetermined pace.

0655In accordance with some embodiments of the electronic device 2700, the processing unit is further configured to: in response to receiving the request to send the message to the at least one other user, send instructions (e.g., with the sending unit 2720) to render a user interface object that includes the animation that draws the stored handwritten input at the predetermined pace.

0656In accordance with some embodiments of the electronic device 2700, the predetermined pace corresponds to a writing pace that was used by the user while providing the stored handwritten input.

0657In accordance with some embodiments of the electronic device 2700, the predetermined pace corresponds to a writing pace that is different from a pace that was used by the user while providing the stored handwritten input.

0658In accordance with some embodiments of the electronic device 2700, after replacing the first set of characters with the representation of the stored handwritten input, the message-input area includes both the representation of the stored handwritten input and at least a first typed input of the plurality of typed inputs.

0659In accordance with some embodiments of the electronic device 2700, the stored sequence of characters corresponds to a label that the user provided for the stored handwritten input.

0660The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0661The operations described above with reference to <figref idref="f0215 f0216">Figures 26A-26B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0217">Figure 27</figref>. For example, some operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0662<figref idref="f0218 f0219">Figures 28A-28B</figref> are flow diagrams illustrating a method 2800 of providing and presenting user-specific handwritten inputs in a messaging application, in accordance with some embodiments. The method 2800 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 2800 are, optionally, combined and/or the order of some operations is, optionally, changed.

0663As described below, the method 2800 provides an intuitive way to provide and present user-specific handwritten inputs in a messaging application. The method helps to improve user satisfaction with their devices and produces more efficient human-machine interfaces by allowing users, e.g., to simply following a predefined training sequence in order to produce a custom keyboard with user-specific handwritten characters as keys on the custom keyboard. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. Furthermore, allowing users to easily, efficiently, and quickly produce custom keyboards with user-specific handwritten characters as keys enhances the operability of the devices and makes user-device interfaces (e.g., in the messaging application) more efficient (e.g., by allowing users to easily customize their message content with handwritten inputs selected from the custom keyboard) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently (e.g., the user need not leave the messaging application, open and use a different application to input or locate handwritten inputs, and then return to use those inputs in the messaging application, instead the user simple provides and/or selects custom handwritten inputs directly within the messaging application).

0664The device detects (2802), via the touch-sensitive surface, a first input (that corresponds to a request to prepare a custom keyboard with handwritten characters, such as input 2326 in order to activate a keyboard preparation mode and then input 2328 in order to display the keyboard preparation user interface for a respective set of training characters, <figref idref="f0202 f0203">Figures 23W-23X</figref>). In response to detecting the first input (or multiple inputs, such as inputs 2326 and 2328), the device presents, on the display, a keyboard preparation user interface (e.g., the user interface shown on <figref idref="f0204">Figure 23Y</figref>). In some embodiments, the keyboard preparation user interface includes (2804) a first portion that displays the predefined set of training characters including a first emphasized character (e.g., the portion of the user interface shown in <figref idref="f0204">Figure 23Y</figref> that displays "THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG." In some embodiments, the first portion is a top portion that provides a preview of characters that will be typed by the user while preparing the custom keyboard and the emphasized character represents that next character to be handwritten by the user while preparing the custom keyboard (e.g., as shown in <figref idref="f0204">Figures 23Y</figref> and <figref idref="f0205">23Z</figref>, the "T" character 2330 is emphasized in the first portion in order to indicate to the user that they should provide handwritten input for that character). In some embodiments, the keyboard preparation user interface also includes: a second portion that displays one or more characters of the predefined set of training characters, the one or more characters including a second emphasized character (e.g., emphasized character 2332, <figref idref="f0204 f0205">Figures 23Y-23Z</figref>). For example the second portion is a bottom portion that is displayed below the first/ top portion and the second portion includes a limited number of characters (e.g., 1, 2, or 3) representing the next characters to be handwritten by the user. In some embodiments, the first and second emphasized characters correspond to the same character, but the second emphasized character is displayed with a larger font size that the first emphasized character, as shown in <figref idref="f0204 f0205">Figures 23Y-23Z</figref>.

0665In some embodiments, emphasized characters in the first and second portions change as the handwritten inputs are received (2806). In some embodiments, in accordance with a determination that a respective handwritten input satisfies acceptance criteria, the device emphasizes a next character in the set of training characters (as shown in <figref idref="f0205 f0206">Figures 23Z-23AA</figref>, the emphasized characters change as the user continues to provide handwritten inputs that satisfy the acceptance criteria. In this way, users are provided with clear visual cues as to the characters they should be handwriting.

0666In some embodiments, in accordance with a determination that a respective handwritten input does not satisfy the acceptance criteria, the device provides an indication to the user as to how the handwritten input should be revised in order to satisfy the acceptance criteria. For example, as shown in <figref idref="f0204">Figure 23Y</figref>, the user provides a handwritten input for the letter "T" but that handwritten input does not satisfy the acceptance criteria and, as such, the device displays the indication 2330 instructing the user to provide a larger handwritten input.

0667While presenting the keyboard preparation user interface, the device receives (2808), via the touch-sensitive surface, handwritten inputs that correspond to a predefined set of training characters (as discussed above in reference to <figref idref="f0204 f0206">Figures 23Y-23AA</figref>). For example, the predefined set of training characters correspond to those characters displayed on a QWERTY keyboard (2810).

0668After receiving the handwritten inputs, the device detects (2812) a second input that corresponds to a request to display a messaging user interface that includes a message-input area and a virtual keyboard with a plurality of keys (e.g., the virtual keyboard is a QWERTY keyboard (such as that shown in <figref idref="f0180">Figure 23A</figref>) or is the custom keyboard with handwritten characters that correspond to the handwritten inputs (such as that shown in <figref idref="f0208">Figure 23AC</figref>)). A first key of the plurality of keys is associated with a first handwritten input of the received handwritten inputs. In some embodiments, the virtual keyboard is a QWERTY keyboard (2814). For example, the keys on the QWERTY keyboard shown on <figref idref="f0180">Figure 23A</figref> are each associated with a respective handwritten input from the user. As another example, the virtual keyboard is a user-specific keyboard with keys, wherein each key includes a representation of one of the received handwritten inputs (such as that shown in <figref idref="f0208">Figure 23AC</figref>).

0669In response to detecting the second input, the device displays (2818) the messaging user interface that includes the message-input area and the virtual keyboard with the plurality of keys. For example the second input corresponds to a request to open a messaging application (e.g., by clicking an icon on a home screen page). The device receives (2818), via the touch-sensitive surface, a selection of the first key (e.g., the user taps over a representation of the "p" key shown on the QWERTY keyboard of <figref idref="f0180">Figure 23A</figref> or the user-specific handwritten keyboard of <figref idref="f0208">Figure 23AC</figref>. In response to receiving the selection of the first key, the device outputs a representation of the first handwritten input within the message-input area (e.g., extending the previous example after the user taps the "p" key on a displayed keyboard the device displays a user-specific handwritten input for the "p" key, such as one provided during the handwriting training exercise discussed above in reference to <figref idref="f0202 f0207">Figures 23W-23AB</figref>)

0670In some embodiments, outputting the representation of the first handwritten input includes (2820) rendering the first handwritten input at a pace that was recorded while receiving the first handwritten input.

0671It should be understood that the particular order in which the operations in <figref idref="f0218 f0219">Figures 28A-28B</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 2800 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 2800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0672In some embodiments, the methods described above in reference to <figref idref="f0211 f0213">Figures 24A-24C</figref>, <figref idref="f0215 f0216">26A-26B</figref>, and <figref idref="f0218 f0219">28A-28B</figref> utilize one or more of the techniques described below to render ink on the display in order to accurately simulate the way that ink is applied to a surface.

Handwriting GL Renderer

0673The handwriting renderer can be defined by two primary systems: wet and dry (as shown in Table 1 below). These are two interdependent rendering pipelines that present the lifecycle of the appearance of ink on screen. In some embodiments, the rendering pipelines work on all supported hardware (e.g., many different configurations of smart phones, laptops, smart watches, etc.). <tables id="tabl0001" num="0001"><img file="EP3620902A1_D0001.tif" /></tables>

0674In some embodiments, each state described above (e.g., in reference to Table 1) represents a frame buffer and contains its own shader pipeline. Wet Intermediate: off-screen, draw arrays using GL_POINTS, made of many overlapping dots using glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA) resulting in the appearance of continuous line color in concert with Dynamic Circularization, time-based particle simulation for Bleed Behavior. Wet Composite: receives Self, Wet Intermediate and paper texture, fragment based normals determination for Specular Wetness, accumulatively fades to 0%, revealing Dry Composite. Dry Intermediate: off-screen, receives Self and Wet Intermediate, pre-processing for Segment Level Multiply Blending. Dry Composite: receives Dry Intermediate and paper texture, applies color from Dry Intermediate results.

0675In some embodiments, when presented to a screen (e.g., display 112 of device 100), Wet Composite is alpha blended on top of Dry Composite.

Bleed Behavior

0676Example equations for rendering bleed behavior that accurately mimics the way ink is applied to a surface is shown in Table 2 below: <tables id="tabl0002" num="0002"><table frame="all"><tgroup cols="1" colsep="0"><colspec colnum="1" colname="col1" colwidth="161mm" colsep="1" /><tbody><row rowsep="0"><entry>life = clamp((time - birth) / lifespan, 0.0, 1.0);</entry></row><row><entry>final_size = max_size ^∗ 0.1 + (max_size ^∗ 0.36 + max_size ^∗ 0.09 ^∗ life) ^∗ speed + (max_size ^∗ 0.45 ^∗ life) ^∗ (force ^∗ 0.8 + speed ^∗ 0.2);</entry></row><row><entry align="center">Table 2</entry></row></tbody></tgroup></table></tables>

0677In some embodiments, the Bleed Behavior is a time-based effect that changes each vertex's point size over a normalized time-of-lifespan. In some embodiments, the size is determined by filtered (smoothed) and normalized values of user pressure (force) and velocity (baked down to speed).

0678In some embodiments, when the simulation has completed its phase for a given point, a channel designated exclusively for the Dry Pipeline to receive is written to (e.g., it is critical that this channel is written to only once per point to avoid alpha over-coverage within the Dry Pipeline).

0679Example equations used to implement a Dynamic Circularization technique are shown in Table 3 below: <tables id="tabl0003" num="0003"><table frame="all"><tgroup cols="1" colsep="0"><colspec colnum="1" colname="col1" colwidth="122mm" colsep="1" /><tbody><row rowsep="0"><entry>one_uv_pixel = 1.0 / point_size;</entry></row><row rowsep="0"><entry>vector_from_center = (gl_PointCoord - 0.5) ^∗ 2.0;</entry></row><row rowsep="0"><entry>dist_squared = dot(vector_from_center, vector_from_center);</entry></row><row><entry>value = 1.0 - linearstep(max(0.0, 1.0 - one_uv_pixel ^∗ 4.0), 1.0, dist squared);</entry></row><row><entry align="center">Table 3</entry></row></tbody></tgroup></table></tables>

0680In some embodiments, during the fragment phase of the Wet Intermediate Pass, each GL_POINT is processed. Based on the point-size and fragment-coordinate of the point, we can ensure that the circularization of the point maintains a consistent edge alpha falloff. This consistency provides a consistent line edge appearance without the expense of MSAA (multi-sampled anti-aliasing) and regardless of line-weight / point-size.

0681An example matrix that illustrates Specular Wetness techniques is shown in Table 4 below: <tables id="tabl0004" num="0004"><img file="EP3620902A1_D0002.tif" /></tables>

0682In some embodiments, using a Laplacian Convolution Matrix for Wet Intermediate and Paper texture color, a two-dimensional vector is created based on adjacent pixel luminance (an example is shown in Table 4). This vector's direction and magnitude is used to compute a three-dimensional vector (normal). This vector is used just like a bump map to create the appearance of Phong shaded wetness based on a light's three dimensional position.

Multiply Blend Using Segment Separation

Intermediate

0683In some embodiments, overlapping line segments are provided in conjunction with particular handwritten inputs. An example is shown in Table 5 below: <tables id="tabl0005" num="0005"><img file="EP3620902A1_D0003.tif" /></tables>

0684For the purposes of the example shown in Table 5, <figref idref="f0010">Figure 5B</figref> is referred to as a NEW_SEGMENT, <figref idref="f0011">Figure 5C</figref> as PREVIOUS_SEGMENT, and <figref idref="f0012">Figure 5D</figref> as DIFF. In some embodiments, when new data is written to the specified channel that the Dry Intermediate is designed to receive from the Wet Intermediate, that data is denoted as NEW_SEGMENT. In some embodiments, the equation shown above in Table 5 is utilized to ensure that DIFF can be added seamlessly to the previous state of a color attachment, providing the same consistent alpha coverage along edges (an example is shown in Table 6, below). <tables id="tabl0006" num="0006"><img file="EP3620902A1_D0004.tif" /></tables>

0685In some embodiments, DIFF is added and clamped to a single channel of an intermediate frame buffer's color attachment to represent ALPHA (5E). <tables id="tabl0007" num="0007"><img file="EP3620902A1_D0005.tif" /></tables>

0686In some embodiments, the following equation is used to help with the bleeding techniques: BLEND = DIFF ^∗ TARGET_MULTIPLIER + (1.0 - DIFF ^∗ TARGET_MULTIPLIER) ^∗ PREVIOUS_BLEND. In some embodiments, the green component in <figref idref="f0014">Figure 5F</figref> of Table 7 as DIFF and the red component as PREVIOUS_BLEND. In some embodiments, DIFF is multiplied by a scalar (TARGET_MULTIPLIER) and added to the inverse of this product of the previous state. The result is written to a single channel representing the multiply blend state. Due to inherent alpha over coverage with this process, alpha is preserved in a separate channel.

Composite

0687In some embodiments, when a request is made to render a pass to the composite frame buffer to be presented to screen, this task is much more trivial than traditional blend mode operations since the work has been done in the intermediate pass and, notably preserves alpha precisely. Other methods take pre-multiplied alpha and do expensive, imprecise work to extract alpha using methods like un-premultiply. <maths id="math0001"><math display="block"><mrow><mi>RGB</mi><mo>=</mo><mi>mix</mi><mfenced><mi>BASE_COLOR</mi><mo>,</mo><mrow><mspace width="1em" /><mi>BLACK</mi></mrow><mo>,</mo><mrow><mspace width="1em" /><mi>linearstep</mi></mrow><mfenced><mi>TARGET_MULTIPLIER</mi><mo>,</mo><mspace width="1em" /><mn>1.0</mn><mo>,</mo><mrow><mspace width="1em" /><mi>BLEND</mi></mrow></mfenced></mfenced><mn>.</mn></mrow></math><img file="EP3620902A1_D0006.tif" /></maths><maths id="math0002"><math display="block"><mrow><mi mathvariant="normal">A</mi><mo>=</mo><mi>ALPHA</mi><mo>*</mo><mi>PAPER_TEXTURE</mi><mn>.</mn></mrow></math><img file="EP3620902A1_D0007.tif" /></maths>

0688In some embodiments, the result from <figref idref="f0014">Figure 5F</figref> as BLEND, the result in <figref idref="f0013">Figure 5E</figref> as ALPHA. In some embodiments, these techniques of generating multiply blending more closely simulates how ink reacts to paper. It works continuously (per segment) within a single stroke and simultaneously with all other pixels in the color attachment.

Multiply Blend Using Segment Collation

0689In some embodiments, while the richness and complexity of segment separation blending may require one pass per segment in a live drawing setting, there are a few cases that require a more optimized method of rendering all non-live drawing data in as few passes as possible (e.g. Undo, Thumbnail, Recents). For these cases, it is ideal to collate as many segments as possible that are known to only overlap their previous segment.

Collision Detection to Determine Pass Endpoint

0690<tables id="tabl0008" num="0008"><img file="EP3620902A1_D0008.tif" /></tables>

0691<figref idref="f0130">Figure 6A</figref> above in Table 8 illustrates an example final composite. <figref idref="f0131">Figure 6B</figref> in Table 8 illustrates the series of passes needed to render 6A.

0692In some embodiments, when all segments are known, fast-enumeration is used to go over each segment to determine two-dimensional vector intersection with all segments within the current pass (This includes detached segments from previous lines. This system is agnostic to beginning and end of complete strokes). When an intersection is determined, this group of vertices is denoted as a single pass by flagging the last segment as an endpoint. In some embodiments, in the second shape of <figref idref="f0131">Figure 6B</figref>, although the second shape appears to intersect with the first shape, these techniques do not determine intersection until an intersection is reached within vectors enumerated since the last intersection.

0693Additional details regarding techniques used in conjunction with the methods described above in reference to <figref idref="f0211 f0213">Figures 24A-24C</figref>, <figref idref="f0215 f0216">26A-26B</figref>, and <figref idref="f0218 f0219">28A-28B</figref> are also provided in <patcit id="pcit0003" dnum="US62349116A"><text>U.S. Provisional Application Serial No. 62/349,116, filed June 12, 2016</text></patcit>, which is incorporated by reference herein.

0694In accordance with some embodiments, <figref idref="f0220">Figure 29</figref> shows a functional block diagram of an electronic device 2900 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0220">Figure 29</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0695As shown in <figref idref="f0220">Figure 29</figref>, an electronic device 2900 includes a display unit 2902 configured to display a user interface, a touch-sensitive surface unit 2904 configured to receive contacts, one or more sensor units 2906 for detecting intensities of contacts on the touch-sensitive surface unit 2904; and a processing unit 2908 coupled with the display unit 2902, the touch-sensitive surface unit 2904 and the one or more sensor units 2906. In some embodiments, the processing unit 2908 includes an input detecting unit 2910, a displaying unit 2912, a selection receiving unit 2914, a handwriting input representation outputting unit 2916, and a handwritten input receiving unit 2918.

0696The processing unit 2908 is configured to detect (e.g., with the input detecting unit 2910), via the touch-sensitive surface, a first input; in response to detecting the first input, present, on the display (e.g., with the displaying unit 2912 in conjunction with the display unit 2902), a keyboard preparation user interface; while presenting the keyboard preparation user interface, receive, via the touch-sensitive surface, handwritten inputs (e.g., with the handwritten input receiving unit 2918) that correspond to a predefined set of training characters; after receiving the handwritten inputs, detect a second input (e.g., with the input detecting unit 2910) that corresponds to a request to display a messaging user interface that includes a message-input area and a virtual keyboard with a plurality of keys, and a first key of the plurality of keys is associated with a first handwritten input of the received handwritten inputs; in response to detecting the second input, display the messaging user interface that includes the message-input area and the virtual keyboard with the plurality of keys (e.g., with the displaying unit 2912); receive, via the touch-sensitive surface, a selection of the first key (e.g., with the selection receiving unit 2914); and in response to receiving the selection of the first key, output a representation of the first handwritten input within the message-input area (e.g., with the handwriting input representation outputting unit 2916).

0697In some embodiments, the predefined set of training characters corresponds to characters displayed on a QWERTY keyboard.

0698In some embodiments, the virtual keyboard is a QWERTY keyboard.

0699In some embodiments, the virtual keyboard is a user-specific keyboard with keys, wherein each key includes a representation of one of the received handwritten inputs.

0700In some embodiments, outputting the representation of the first handwritten input includes rendering the first handwritten input at a pace that was recorded while receiving the first handwritten input.

0701In some embodiments, the keyboard preparation user interface includes: a first portion that displays the predefined set of training characters including a first emphasized character, and a second portion that displays one or more characters of the predefined set of training characters, the one or more characters including a second emphasized character.

0702In some embodiments, emphasized characters change as the handwritten inputs are received.

0703The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0704The operations described above with reference to <figref idref="f0218 f0219">Figures 28A-28B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0220">Figure 29</figref>. For example, some operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Selectively scrunch content in a message transcript

0705<figref idref="f0221 f0227">Figures 30A-30G</figref> illustrate example user interfaces for quickly locating different types of content in a messaging application, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below. Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface 451 that is separate from the display 450, as shown in <figref idref="f0006">Figure 4B</figref>. For convenience of explanation, the embodiments described below will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, a focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch-sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces discussed below, along with a focus selector.

0706As shown in <figref idref="f0221">Figure 30A</figref>, in some embodiments, users are able to quickly locate different types of content in a messaging application by scrunching down content in order to easily locate desired content. A user provides a gesture 3002 in <figref idref="f0221">Figure 30A</figref> and, in response, the device reduces a display size (i.e., scrunches/ squishes down) message regions that include content having a first content type (e.g., message regions with text-only content are reduced in size, such as the content for message region 3003, <figref idref="f0222">Figure 30B</figref>). In some embodiments, as a user continues to provide a gesture (e.g., gesture 3004 is a continuation of gesture 3002 but, in some embodiments, gesture 3004 is a distinct gesture from gesture 3002), the message regions are further reduced in size (e.g., message region 3003 is further reduced in size, <figref idref="f0223">Figure 30C</figref>).

0707Users are able to intuitively provide additional gestures (or continue providing a single gesture) that reduce a display size for content types other than the first content type. As shown in <figref idref="f0224">Figure 30D</figref>, in response to gesture 3006 (<figref idref="f0223">Figure 30C</figref>), content items having a second content type (e.g., text with emojis) are displayed with a reduced display size (such as message region 3001). As shown in <figref idref="f0225">Figure 30E</figref>, in response to gesture 3008 (<figref idref="f0224">Figure 30D</figref>), content items having a third content type (e.g., text that includes text-rendering effects) are displayed with a reduced display size (such as message region 3009, <figref idref="f0225">Figure 30E</figref>). As shown in <figref idref="f0226">Figure 30F</figref>, in response to gesture 3010, content items having a fourth content type (e.g., graphical content, such as images and maps objects) are displayed with a reduced display size (such as message region 3005 and 3011, <figref idref="f0226">Figure 30F</figref>).

0708In some embodiments, users are also able to quickly expand portions of the messaging user interface in response to a de-pinch gesture (e.g., gesture 3012). In response to detecting gesture 3012, the device increases display sizes for all content types (<figref idref="f0226 f0227">Figures 30F-30G</figref>), until the message regions return to their respective default sizes. In this way, users are easily able to search out desired content without having to aimlessly scroll through a long and confusing conversation transcript (instead users simply scrunch down content so that they can quickly see a high-level overview of content items in the conversation transcript and, once desired information is located, users can expand content items to view the desired information and message regions that are surrounding the desired information).

0709<figref idref="f0228 f0229">Figures 31A-31B</figref> are flow diagrams illustrating a method 3100 of quickly locating different types of content in a messaging application, in accordance with some embodiments. The method 3100 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 3100 are, optionally, combined and/or the order of some operations is, optionally, changed.

0710As described below, the method 3100 provides an intuitive way to locate different types of content in a messaging application. The method produces more efficient human-machine interfaces by allowing users to use a simple gesture to quickly scale down display sizes for content in a messaging application, so that users are able to quickly locate desired content (e.g., users can scale down all text-only content in order to quickly locate emojis, photos, videos, or other types of content that may have been received a long time ago). For battery-operated devices, the method helps to conserve power and increase the time between battery charges (e.g., by allowing users to quickly locate desired content instead forcing users to employ inefficient and battery-draining techniques). Furthermore, allowing users to quickly locate desired content enhances the operability of the devices and makes user-device interfaces (e.g., in the messaging application) more efficient by allowing users to easily locate desired content in a potentially large and difficult to search conversation transcript. The user need not scroll through pages and pages of content in the conversation transcript and can instead simply provide intuitive gestures to easily scale down content so that desired content is easily located.

0711The device displays (3102), on the display, a messaging user interface that includes a plurality of content items. In some embodiments, the messaging user interface includes a conversation transcript of a messaging session between a user of the electronic device and at least one other user, as shown in <figref idref="f0221">Figure 30A</figref>. In some embodiments, the plurality of content items includes content items having a first content type. For example, each content item of the first content type is text-based and does not include any emojis or other text-rendering effects (such as making the text appear or disappear in response to a gesture over a content item, also referred to herein as an invisible ink effect or a private message). In some embodiments, the first content type includes text-only messages sent and received via the messaging user interface. In some embodiments, a content item corresponds to content included in a single user interface element displayed in the messaging user interface (e.g., a single message region or bubble). Message region 3003 is a one example shown in <figref idref="f0221">Figure 30A</figref> of a content item that includes content of the first content type.

0712In some embodiments, the plurality of content items includes content items having a second content type that is distinct from the first content type. For example, the second content type corresponds to messages containing content other than text-only content, such as emojis or graphical content sent and received via the message user interface, such as camera images, screenshots, maps objects, objects with text-rendering effects, and the like. In some embodiments, content items having the second content type include message regions that include text and emojis (e.g., message region 3001, <figref idref="f0221">Figure 30A</figref>). As described in more detail below, the messaging user interface may include content items having a third content type (e.g., the content included in message region 3009, <figref idref="f0223">Figure 30C</figref>) and a fourth content type (e.g., the content included in message region 3005 and image 3011, <figref idref="f0221">Figures 30A</figref> and <figref idref="f0224">30D</figref>) as well.

0713In some embodiments, a respective content item in the plurality of content items is displayed with a respective first size. In some embodiments, each content item is displayed with a respective default display size. In some embodiments, different default sizes are associated with the content types (e.g., pictures and other graphical content have a different default display size than text-only content items).

0714While displaying the messaging user interface (and, in some embodiments, while a focus selector is over the messaging user interface), the device detects (3104), via the touch-sensitive surface, a first input. In some embodiments, the first input (e.g., a first portion of a pinch gesture, such as gesture 3002 shown in <figref idref="f0221">Figure 30A</figref>) corresponds to a first request to reduce a display size (or a magnification level) for at least a portion of the content items in the plurality of content items. In some embodiments, the first request is received while some textual-only content is displayed within the messaging user interface (e.g., the message regions that include text-only content including message region 3003, as shown in <figref idref="f0221">Figure 30A</figref>).

0715In response to detecting the first input, the device reduces (3106) a display size of at least some content items having the first content type while continuing to display content items having the second content type with their respective first size. In some embodiments, reducing the display size includes reducing the display size for all content items having the first content type. In some embodiments, reducing the display size includes reducing the display size for only those content items having the first content type that are currently visible on the display (e.g., items of the first content type may or may not have a reduced display size while they are not currently visible within the portion of the messaging session that is visible within the messaging user interface on the display). As shown in <figref idref="f0222">Figure 30B</figref>, in response to the gesture 3002, the device reduces a display size of the message region 3003 (and for other message regions that include text-only content).

0716In this way, users can easily scrunch or squish down content of a first type (e.g., text-only content) within a messaging user interface in order to quickly search for other content having a type other than the first type. For example, a user can quickly search for a desired photograph or video, without having to scroll through pages and pages of text-only content, thereby quickly, efficiently, and intuitively locating desired (non-textual) content. Additionally, in some embodiments, after content has been squished down, timestamps that are displayed in the conversation transcript are easily visible and, thus, users can quickly search through a lengthy conversation transcript to find a relevant time period. In other embodiments, any other user interface could employ the aforementioned features. For example, any user interface that includes content of a variety of content types, such as a web browser user interface (including images, text, videos, etc.), an electronic book user interface (including text, images associated with the text, etc.), and others.

0717In some embodiments, in conjunction with reducing the display size of at least some content items having the first content type, the device provides (3108) haptic feedback. In some embodiments, haptic feedback is provided whenever display sizes for any of the content items is reduced (to indicate either that the gesture was received or that the gesture/ input was "legal.") (e.g., any type a messaging bubble is scrunched down, the device provides haptic feedback).

0718In some embodiments, reducing the display size includes (3110) reducing the display size in accordance with a determination that a characteristic (distance travelled, space between fingers in a pinch gesture, characteristic intensity of contact) of the first input satisfies first display-size-reduction criteria that are associated with the first content type.

0719In some embodiments, after reducing the display size of at least some of the content items having the first content type, the device detects (3112), via the touch-sensitive surface, a second input that corresponds to a request to scroll the messaging user interface. In response to detecting the second input, the device scrolls the messaging user interface while continuing to display: at least some of the content items having the first content type with the reduced display size, and content items having the second content type with their respective first sizes. In this way, users are easily able to scroll and search for desired content while keeping some content items at reduced display sizes (in order to assist in more easily locating desired content items).

0720In some embodiments, the user is able to provide a series of gestures or one continuous gesture in order to scrunch down display sizes for content within the messaging user interface. For example, in response to gesture 3004, the device continues to reduced display sizes for content have the first content type (e.g., message region 3003 is further reduced in size as compared to its size in <figref idref="f0222">Figure 30B</figref>).

0721In some embodiments, the device detects (3114) a third input (e.g., a pinch gesture or a portion thereof, such as gesture 3006, shown in <figref idref="f0223">Figure 30C</figref>). In response to detecting the third input, the device reduces a display size of content items having the second content type. For example, as shown in <figref idref="f0224">Figure 30D</figref>, in response to gesture 3006 shown in <figref idref="f0223">Figure 30C</figref>, the display size for content items having the second content type is reduced (e.g., message region 3001 is now displayed with a reduced display size in accordance with the gesture 3008).

0722In some embodiments, the messaging user interface includes content items having a third content type (e.g., content included in message region 3009 includes text that is associated with a text-rendering effect). The device, after reducing display size of the at least some of the content items having the first and second content types, detects (3116) a fourth input (e.g., a pinch gesture or a portion thereof, such as gesture 3008 shown in <figref idref="f0224">Figure 30D</figref>). In response to detecting the fourth input, the device reduces a display size of at least some of the content items having the third content type. (e.g., as shown in <figref idref="f0225">Figure 30E</figref>, a display size for the message region 3009 is reduced).

0723In some embodiments, the messaging user interface includes content items having a fourth content type (e.g., message regions that include graphical content, such as images, maps objects, and other types of graphical content). After reducing display size of the at least some of the content items having the first, second, and third content types, the device detects a fifth input (e.g., a pinch gesture or a portion thereof, such as gesture 3010 shown in <figref idref="f0225">Figure 30E</figref>). In response to detecting the fifth input, the device reduces a display size of at least some of the content items having the fourth content type (e.g., as shown in <figref idref="f0226">Figure 30F</figref>, the device reduces a display size for content included in message region 3011 (an image) and message region 3005 (a maps object).

0724In some embodiments, reducing display sizes for the at least some content items having each of the first, second, third, and fourth content types is performed based on a hierarchical order (e.g., a predefined order of importance) assigned to each of the content types. In other words, some embodiments include at least four different content types that are scrunched down one after another in response to inputs (e.g., pinch gestures or portions of a single pinch gesture). For example, messaging bubbles with only text are scrunched down first, then messaging bubbles that include emojis are scrunched down, followed by messaging bubbles that are associated with a text-rendering effect (e.g., private messages), and then photos that are included in the conversation transcript are scrunched down (in some embodiments, the photos are not included in messaging bubbles).

0725In some embodiments, the device receives a new input (e.g., one or more de-pinch gestures, such as gesture 3012, <figref idref="f0226">Figure 30F</figref>). In response to receiving the new input, the device reverts display size of the at least some content items having the first content type back to the respective first size (as shown in <figref idref="f0227">Figure 30G</figref> display sizes for message regions that include content items having first (3003), second (3001), and fourth (3005) content types are all returned to their respective first/ default sizes. In some embodiments, the new input may be utilized to revert display sizes for any content items that have been scrunched down back to their respective first sizes (e.g., as shown in <figref idref="f0226 f0227">Figures 30-F-30G</figref>, the de-pinch gesture 3012 is used to quickly increase display sizes for content items having a number of content types). In some embodiments, the user is able to gradually perform the de-pinch gesture 3012 and each content item have each respective content type will revert back to its respective first size at an appropriate time.

0726In some embodiments, at any point during method 3100 (or method 3300 below) if a new message is received (and then displayed within a new message region within the messaging user interface), the device displays that message bubble at its respective first size (instead of displaying it as being scrunched down). In this way, users are still able to view new messages.

0727It should be understood that the particular order in which the operations in <figref idref="f0228 f0229">Figures 31A-31B</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 3100 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 3100 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0737In accordance with some embodiments of the electronic device 3200, the messaging user interface includes content items having a fourth content type, and the processing unit is further configured to: after reducing display size of the at least some of the content items having the first, second, and third content types, detect a fifth input (e.g., with the input detecting unit 3212); and, in response to detecting the fifth input, reduce a display size of at least some of the content items having the fourth content type (e.g., with the display size reducing unit 3214).

0738In accordance with some embodiments of the electronic device 3200, reducing display sizes for the at least some content items having each of the first, second, third, and fourth content types is performed based on a hierarchical order assigned to each of the content types.

0739The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0740The operations described above with reference to <figref idref="f0228 f0229">Figures 31A-31B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0230">Figure 32</figref>. For example, some operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0741<figref idref="f0231 f0232">Figures 33A-33B</figref> are flow diagrams illustrating a method 3300 of quickly locating different types of content in a messaging application, in accordance with some embodiments. The method 3300 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 3300 are, optionally, combined and/or the order of some operations is, optionally, changed.

0742As described below, the method 3300 provides an intuitive way to locate different types of content in a messaging application. The method produces more efficient human-machine interfaces by allowing users to use a simple gesture to quickly scale down display sizes for content in a messaging application, so that users are able to quickly locate desired content (e.g., users can scale down all text-only content in order to quickly locate emojis, photos, videos, or other types of content that may have been received a long time ago). For battery-operated devices, the method helps to conserve power and increase the time between battery charges (e.g., by allowing users to quickly locate desired content instead forcing users to employ inefficient and battery-draining techniques). Furthermore, allowing users to quickly locate desired content enhances the operability of the devices and makes user-device interfaces (e.g., in the messaging application) more efficient by allowing users to easily locate desired content in a potentially large and difficult to search conversation transcript. For example, the user need not scroll through pages and pages of content in the conversation transcript and can instead simply provide intuitive gestures to easily scale down content so that desired content is easily located.

0743The device displays (3302), on the display, a messaging user interface that includes a plurality of content items. In some embodiments, the messaging user interface includes a conversation transcript of a messaging session between a user of the electronic device and at least one other user, as shown in <figref idref="f0221">Figure 30A</figref>. In some embodiments, the plurality of content items includes content items having a first content type. For example, each content item of the first content type is text-based and does not include any emojis or other text-rendering effects (such as making the text appear or disappear in response to a gesture over a content item, also referred to herein as an invisible ink effect or a private message). In some embodiments, the first content type includes text-only messages sent and received via the messaging user interface. In some embodiments, a content item corresponds to content included in a single UI element displayed in the messaging user interface (e.g., a single message region or bubble). Message region 3003 is a one example shown in <figref idref="f0221">Figure 30A</figref> of a content item that includes content of the first content type.

0744In some embodiments, the plurality of content items includes content items having a second content type that is distinct from the first content type. For example, the second content type corresponds to messages containing content other than text-only content, such as emojis or graphical content sent and received via the message user interface, such as camera images, screenshots, maps objects, objects with text-rendering effects, and the like. In some embodiments, content items having the second content type include message regions that include text and emojis (e.g., message region 3001, <figref idref="f0221">Figure 30A</figref>). As described in more detail below, the messaging user interface may include content items having a third content type (e.g., the content included in message region 3009, <figref idref="f0223">Figure 30C</figref>) and a fourth content type (e.g., the content included in message region 3005 and image 3011, <figref idref="f0221">Figures 30A</figref> and <figref idref="f0224">30D</figref>) as well.

0745In some embodiments, a respective content item in the plurality of content items is displayed with a respective first size. In some embodiments, each content item is displayed with a respective default display size. In some embodiments, different default sizes are associated with the content types (e.g., pictures and other graphical content have a different default display size than text-only content items).

0746While displaying the messaging user interface (and, in some embodiments, while a focus selector is over the messaging user interface), the device detects (3304), via the touch-sensitive surface, a first input. In some embodiments, the first input (e.g., a first portion of a pinch gesture, such as gesture 3002 shown in <figref idref="f0221">Figure 30A</figref>) corresponds to a first request to reduce a display size (or a magnification level) for at least a portion of the content items in the plurality of content items. In some embodiments, the first request is received while some textual-only content is displayed within the messaging user interface (e.g., the message regions that include text-only content including message region 3003, as shown in <figref idref="f0221">Figure 30A</figref>).

0747In response to detecting the first input, the device reduces (3306) a display size of at least some content items having the first content type, such that a first content item having the first content type is reduced to a respective second size that is smaller than the respective first size by a predefined first display-size-reduction factor (e.g., content included in the message region 3003 is reduced from a first size, <figref idref="f0221">Figure 30A</figref>, and then to a second size, Figure B). In response to detecting the first input, the device also reduces (3306) a display size of at least some content items having the second content type, such that a second content item having the second content type is reduced to a respective third size that is smaller than the respective first size by a predefined second display-size-reduction factor (e.g., content included in the message region 3001 is reduced from a first size, <figref idref="f0223">Figure 30C</figref>, to a second size, <figref idref="f0224">Figure 30D</figref>). In some embodiments, the reduction in size for the message region 3001 is performed in response to gesture 3002 and/or 3004. In some embodiments, the predefined second display-size-reduction factor is less than the predefined first display-size-reduction factor. Stated another way, the content items having the first content type are reduced to a smaller display size relative to the content items having the second content type (the content items have the first content type are scrunched down more than the content items having the second content type). In some embodiments, the content items having the second content type are only slightly reduced in size, so as to provide a visual cue to the user that the content items having the second content type can be further reduced in size by providing additional inputs (e.g., additional pinch gestures). For example, as shown in <figref idref="f0224">Figure 30D</figref>, message regions that include text-only content (e.g., message region 3003, <figref idref="f0224">Figure 30D</figref>) are scrunched down more than message regions that include content in addition to text (e.g., message region 3001, <figref idref="f0224">Figure 30D</figref>).

0748Operations 3308 and 3310 correspond to operations 3108 and 3110, respectively, discussed above in reference to <figref idref="f0228">Figure 31A</figref>. As such, the descriptions above in reference to operations 3108 and 3110 are applicable to operations 3308 and 3310 as well.

0749In some embodiments, after reducing the display size of at least some of the content items having the first content type and at least some of the content items having the second content type, the device detects (3312), via the touch-sensitive surface, a second input that corresponds to a request to scroll the messaging user interface. In response to detecting the second input, the device scrolls the messaging user interface while maintaining displayed sizes of content items having the first content type at the respective second size and content items having the second content type at the respective third size.

0750In some embodiments, the device detects (3314) a third input and, in response, the device further reduces a display size of content items having the second content type (e.g., as shown in <figref idref="f0225">Figure 30E</figref>, the device further reduces message region 3001 and the contained included therein in response to a continuation of or new pinch gesture, such as gesture 3008).

0751Operations 3316, 3318, 3320, and 3322 correspond to operations 3116, 3118, 3120, and 3122, respectively, discussed above in reference to <figref idref="f0228">Figure 31A</figref>. As such, the descriptions above in reference to operations 3116, 3118, 3120, and 3122 are applicable to operations 3316, 3318, 3320, and 3322 as well.

0752It should be understood that the particular order in which the operations in <figref idref="f0231 f0232">Figures 33A-33B</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 3300 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 3300 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

0753In accordance with some embodiments, <figref idref="f0233">Figure 34</figref> shows a functional block diagram of an electronic device 3400 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0233">Figure 34</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

0754As shown in <figref idref="f0233">Figure 34</figref>, an electronic device 3400 includes a display unit 3402 configured to display a user interface, a touch-sensitive surface unit 3404 configured to receive contacts, one or more sensor units 3406 for detecting intensities of contacts on the touch-sensitive surface unit 3404; and a processing unit 3408 coupled with the display unit 3402, the touch-sensitive surface unit 3404 and the one or more sensor units 3406. In some embodiments, the processing unit 3408 includes a displaying unit 3410, an input detecting unit 3412, a display size reduction unit 3414, a haptic feedback providing unit 3416, and a display size reverting unit 3418.

0755The processing unit 3408 is configured to display (e.g., with the displaying unit 3410), on the display (e.g., display unit 3402), a messaging user interface that includes a plurality of content items. In some embodiments, the plurality of content items includes content items having a first content type, the plurality of content items includes content items having a second content type that is distinct from the first content type, and a respective content item in the plurality of content items is displayed with a respective first size. While displaying the messaging user interface, detect (e.g., with the input detecting unit 3412), via the touch-sensitive surface, a first input and, in response to detecting the first input: reduce a display size (e.g., with the display size reducing unit 3414) of at least some content items having the first content type, such that a first content item having the first content type is reduced to a respective second size that is smaller than the respective first size by a predefined first display-size-reduction factor; and reduce a display size (e.g., with the display size reducing unit 3414) of at least some content items having the second content type, such that a second content item having the second content type is reduced to a respective third size that is smaller than the respective first size by a predefined second display-size-reduction factor. In some embodiments, the predefined second display-size-reduction factor is less than the predefined first display-size-reduction factor.

0756In accordance with some embodiments of the electronic device 3400, the processing unit is configured to: after reducing the display size of at least some of the content items having the first content type, detecting, via the touch-sensitive surface, a second input (e.g., with the input detecting unit 3412) that corresponds to a request to scroll the messaging user interface; and, in response to detecting the second input, scrolling the messaging user interface while continuing to display: at least some of the content items having the first content type with the reduced display size, and content items having the second content type with their respective first sizes (e.g., with the displaying unit 3410).

0757In accordance with some embodiments of the electronic device 3400, the processing unit is configured to: detect a third input (e.g., with the input detecting unit 3412) and, in response to detecting the third input, further reduce display size of each content item having the second content type (e.g., with the display size reducing unit 3414).

0758In accordance with some embodiments of the electronic device 3400, the processing unit is further configured to: in conjunction with reducing the display size of at least some content items having the first content type, provide haptic feedback (e.g., with the haptic feedback providing unit 3416).

0759In accordance with some embodiments of the electronic device 3400, the processing unit is further configured to: receive a new input; and, in response to receiving the new input, revert display size (e.g., with the display size reverting unit 3418) of the at least some content items having the first content type back to the respective first size.

0760In accordance with some embodiments of the electronic device 3400, reducing the display size includes reducing the display size in accordance with a determination that a characteristic of the first input satisfies first display-size-reduction criteria that are associated with the first content type (e.g., with the display size reducing unit 3414).

0761In accordance with some embodiments of the electronic device 3400, the processing unit is further configured to: detect a third input (e.g., with the input detecting unit 3412) and, in response to detecting the third input, reduce a display size of content items having the second content type (e.g.., with the display size reducing unit 3414).

0762In accordance with some embodiments of the electronic device 3400, the messaging user interface includes content items having a third content type, and the processing unit is further configured to: after reducing display size of the at least some of the content items having the first and second content types, detect a fourth input (e.g., with the input detecting unit 3412) and, in response to detecting the fourth input, reduce a display size of at least some of the content items having the third content type (e.g., with the display size reducing unit 3414).

0763In accordance with some embodiments of the electronic device 3400, the messaging user interface includes content items having a fourth content type, and the processing unit is further configured to: after reducing display size of the at least some of the content items having the first, second, and third content types, detect a fifth input (e.g., with the input detecting unit 3412); and, in response to detecting the fifth input, reduce a display size of at least some of the content items having the fourth content type (e.g., with the display size reducing unit 3414).

0764In accordance with some embodiments of the electronic device 3400, reducing display sizes for the at least some content items having each of the first, second, third, and fourth content types is performed based on a hierarchical order assigned to each of the content types.

0765The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0766The operations described above with reference to <figref idref="f0231 f0232">Figures 33A-33B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0233">Figure 34</figref>. For example, some operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Integrated messaging

0767<figref idref="f0234 f0275">Figures 35A-35AP</figref> illustrate exemplary user interfaces for integrating a digital camera into a messaging application in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in <figref idref="f0560 f0563">Figures 42A-42D</figref>. For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch- sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

0768<figref idref="f0234 f0256">Figures 35A-35W</figref> and <figref idref="f0271 f0275">35AL-35AP</figref> illustrate exemplary user interface 3500 for a messaging application which includes conversation transcript 3503, message-input area 3502, either of application expansion affordance 3702 or three activatable affordances-digital image affordance 3504, digital canvas affordance 3506, and application affordance 3508-either of digital keyboard 3501 or digital image tray 3806, which includes live preview image 3514 from an associated digital camera, including image capture affordance 3516 and camera switching affordance 3505 for switching the live preview image between two or more associated digital cameras, and previously captured digital images 3518. Conversation transcript 3503 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100 and other users included in the messaging session. Each of the other users included in the messaging transcript are represented by an avatar (e.g., avatar 3510 for "Abe") displayed in stack of avatars 4002.

0769<figref idref="f0257 f0270">Figures 35X-35AK</figref> illustrate exemplary user interface 3509 for editing digital images, optionally operated within the messaging application, which includes display of digital image 3518-4, editing affordances that enable different editing modes-pencil affordance 3552, magnification loupe affordance 3554, text affordance 3556, and handwriting affordance 3558-color selection affordances 3548 for setting a color for an editing affordance tool, size selection affordance 3550 for setting the size of a line, text, or handwriting made on the digital image, canceling affordance 3549 for canceling edits to the digital image, and saving affordance 3551 for saving edits to the digital image.

0770<figref idref="f0234 f0242">Figures 35A-35I</figref> illustrate two exemplary embodiments for capturing a digital image and posting the captured image to the messaging transcript (e.g., the messaging session) without leaving the messaging application. In both embodiments, a digital camera is accessed in a messaging user interface displaying message transcript 3503 and keyboard 3501, as illustrated in <figref idref="f0234">Figure 35A</figref>, by detecting activation of digital image affordance 3504 by contact 3512 in <figref idref="f0235">Figure 35B</figref>. In response, digital image tray 3806 replaces digital keyboard 3501 in <figref idref="f0236">Figures 35C</figref> and <figref idref="f0241">35H</figref>.

0771In a first embodiment, device 100 detects a tap gesture including contact 3512 on image capture affordance 3516 in <figref idref="f0237">Figure 35D</figref>. In response, device 100 captures live preview image 3514, creating digital image 3518-5, and places the image (e.g., a representation of the image) in message-input area 3502, which expands to accommodate the image, in <figref idref="f0238">Figure 35E</figref>. The device then detects a tap gesture including contact 3522 on message-content posting affordance 3520 in <figref idref="f0239">Figure 35F</figref>. In response, device 100 posts captured digital image 3518-5 to the messaging session, displaying the image in conversation transcript 3503 in <figref idref="f0240">Figure 35G</figref>.

0772In a second embodiment, device 100 detects a press gesture including contact 3524 on image capture affordance 3516 in <figref idref="f0241">Figure 35H</figref>. Device 100 then detects an increase in the intensity of contact 3524 above a predefined intensity threshold (e.g., IT_L or IT_D) and, in response, captures live preview image 3514, creating digital image 3518-5 in <figref idref="f0242">Figure 35I</figref>. In contrast to the first embodiment-where the intensity of contact 3512 did not increase above the predefined intensity threshold-device 100 posts captured digital image 3518-5 directly to the messaging session, displaying the image in conversation transcript 3503 in <figref idref="f0242">Figure 35I</figref>, because the intensity of contact 3516 reached the predefined intensity threshold.

0773<figref idref="f0243 f0248">Figures 35J-35O</figref> illustrate an exemplary embodiment where a message is associated with a posted digital image. Device 100 detects a tap gesture including contact 3526 on image capture affordance 3516 in <figref idref="f0243">Figure 35J</figref>. In response, device 100 captures live preview image 3514, creating digital image 3518-5, and places the image (e.g., a representation of the image) in message-input area 3502, which expanded to accommodate the image in <figref idref="f0244">Figure 35K</figref>. The device then detects a tap gesture including contact 3528 in message-input area 3502 in <figref idref="f0245">Figure 35L</figref>. In response, device 100 replaces display of digital image tray 3806 with digital keyboard 3501, further expands message-input area 3502 to accommodate a message, and displays text cursor 3842 in <figref idref="f0246">Figure 35M</figref>. Device 100 also detects input of message 3530 and displays the message in message-input area 3502, along with captured digital image 3518-5 in <figref idref="f0246">Figure 35M</figref>. The device then detects a tap gesture including contact 3532 on message-content posting affordance 3520 in <figref idref="f0247">Figure 35N</figref>. In response, device 100 posts captured digital image 3518-5 and message 3530 to the messaging session, displaying the image and message, in message region 3534, within conversation transcript 3503 in <figref idref="f0248">Figure 35O</figref>. Because message 3530 was posted from message-input area 3502 at the same time as image 3518-5, message region 3534 is displayed as overlapping with image 3518-5 in <figref idref="f0248">Figure 35O</figref>.

0774<figref idref="f0249 f0250">Figures 35P-35Q</figref> illustrate an exemplary embodiment where a swipe gesture reveals additional digital images. Device 100 detects a swipe gesture including movement 3538 of contact 3536 to the left, from position 3536-a in <figref idref="f0249">Figure 35P</figref> to position 3536-b in <figref idref="f0250">Figure 35Q</figref>. In response, the device moves digital image tray 3806 to the left, in accordance with movement 3538, creating the appearance that live preview image 3514 slides off of the left side of touch screen 112 and additional digital images 3518-6 and 3518-7 slide onto the display from the right side of touch screen 112, in <figref idref="f0250">Figure 35Q</figref>.

0775<figref idref="f0251 f0255">Figures 35R-35V</figref> illustrate two exemplary embodiments where a previously captured digital image is previewed and posted to the messaging session.

0776In a first embodiment, device 100 detects a press gesture including contact 3540 on previously captured digital image 3518-4 in <figref idref="f0251">Figure 35R</figref>. Device 100 then detects an increase in the intensity of contact 3540 above a first predefined intensity threshold (e.g., IT_L) and, in response, displays enlarged preview 3507 of image 3518-4 over portions of digital image tray 3806 and conversation transcript 3503 in <figref idref="f0252">Figure 35S</figref>. The device then detects a decrease in the intensity of contact 3540 and, in response, ceases display of enlarged preview 3507 in <figref idref="f0253">Figure 35T</figref>.

0777In a second embodiment, device 100 detects a press gesture including contact 3544 on previously captured digital image 3518-4, and then an increase in the intensity of contact 3540 above a first predefined intensity threshold (e.g., IT_L), in <figref idref="f0254">Figure 35U</figref>. In response, the device displays enlarged preview 3507 of image 3518-4 over portions of digital image tray 3806 and conversation transcript 3503 in <figref idref="f0254">Figure 35U</figref>.

Device 100-1 detects a drag gesture, including movement 3922 of contact 3920, which was initiated on electronic sticker 3910, from position 3920-a, within sticker pack 3904, in <figref idref="f0490">Figure 39K</figref> to position 3920-b, still within sticker pack 3904 in <figref idref="f0491">Figure 39L</figref>. In response, sled sticker 3910 is dragged from its initial position 3910-a in sticker pack 3904, in <figref idref="f0490">Figure 39K</figref>, to position 3910-b still within sticker pack 3904, in <figref idref="f0491">Figure 39L</figref>, in accordance with movement 3922. Upon lift-off of contact 3920 within sticker pack 3904, sled sticker 3910 is not posted to the messaging session, because it was not dragged into the conversation transcript, as displayed in its original position 3920-a in <figref idref="f0492">Figure 39M</figref>.

0865In a fourth embodiment, an electronic sticker is dragged into the conversation transcript by a drag gesture, and is posted to the messaging session at a nearest predefined position to the location it was dragged to in the conversation transcript. Device 100-1 detects a drag gesture, including movement 3926 of contact 3924, which was initiated on electronic sticker 3908, from position 3924-a, within sticker pack 3904, in <figref idref="f0493">Figure 39N</figref> to position 3924-b, within conversation transcript 3700 in <figref idref="f0494">Figure 39O</figref>. In response, snowflake sticker 3908 is dragged from its initial position 3908-a in the sticker pack, in <figref idref="f0493">Figure 39N</figref>, to position 3908-c within the conversation transcript, in <figref idref="f0494">Figure 39O</figref>, in accordance with movement 3926. Upon lift-off of contact 3924 within conversation transcript 3700, snowflake sticker 3908 is repositioned to position 3908-d, which corresponds to the nearest location within a message region (e.g., message region 3749) to the position the sticker was at when the device detected lift-off of the contact corresponding to the drag gesture (e.g., location 3908-c).

0866In a fifth embodiment, an electronic sticker is posted directly to the messaging session, at the next temporal position for a message posted in the transcript, in response to detecting a deep press gesture. Device 100-1 detects a press gesture including contact 3932 on snowman sticker 3906 in <figref idref="f0504">Figure 39Y</figref>. Device 100-1 then detects an increase in the intensity of contact 3932 above a predefined intensity threshold (e.g., IT_L or IT_D) and, in response, posts snowman sticker directly to the messaging session, as displayed at position 3906-c, corresponding to the next temporal position for a message posted in transcript 3700, as shown in <figref idref="f0506">Figure 39AA</figref>.

0867<figref idref="f0495 f0503">Figures 39P-39X</figref> illustrate exemplary embodiments where the electronic sticker in animated. In <figref idref="f0495">Figure 39P</figref>, snowman sticker 3906 is displayed at location 3906-b in conversation transcript 3700, as it was placed in <figref idref="f0487 f0489">Figures 39H-39J</figref>.

0886<figref idref="f0552 f0559">Figures 41A-41H</figref> illustrate exemplary user interfaces for integrating data detectors into a messaging application in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in <figref idref="f0614 f0615">Figures 70A-70B</figref>. For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch- sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

0887<figref idref="f0552 f0559">Figures 41A-41H</figref> illustrate two exemplary embodiments where a first electronic device 100-1 detects a word or phrase, in a messaged received from a second electronic device associated with another user included in the messaging session, associated with additional content available on the internet. <figref idref="f0552">Figure 41A</figref> illustrates an exemplary user interface 3500 for a messaging application which includes conversation transcript 3503, message-input area 3502, three activatable affordances-digital image affordance 3504, digital canvas affordance 3506, and application affordance 3508. Conversation transcript 3503 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100-1 and other users included in the messaging session. Each of the other users included in the messaging transcript are represented by an avatar (e.g., avatar 4008 for "Mary Todd") displayed in stack of avatars 4002.

0888In a first embodiment, the device prompts the user to view additional content associated with the identified word or phrase within the messaging user interface by displaying a selectable affordance. Device 100-1 receives message 4102 from Mary Todd, displayed in conversation transcript 3503 in <figref idref="f0552">Figure 41A</figref>. The device recognizes phrase 4101 ("Meteorite Catcher") as the name of a movie about which information is available on the internet. In response, the device displays selectable affordance 4104, prompting the user to "See more information" about the movie. The device then detects a tap gesture, including contact 4106, on selectable affordance 4104 in <figref idref="f0553">Figure 41B</figref>. In response, the device displays information area 4108 displaying information about the movie found on the internet, including a representation 4110 of a poster for the film and biographical information 4112 about the movie, in <figref idref="f0554">Figure 41C</figref>.

0889In a second embodiment, the device prompts the user to view additional content associated with the identified word or phrase in a separate search user interface by highlighting the word or phrase. Device 100-1 receives message 4114 from Abe, displayed in conversation transcript 3503 in <figref idref="f0555">Figure 41D</figref>. The device recognizes phrase 4103 ("Astron Omer") as the name of an actor about whom information is available on the internet. In response, the device displays highlighting 4116 of phrase 4103, prompting the user to select the phrase. The device then detects a tap gesture, including contact 4118, on phrase 4103 in <figref idref="f0556">Figure 41E</figref>. In response, the device displays search user interface 3661 displaying categorized results-new articles 3664, 3678, and 3680 and movie previews 3670, 3682, and 3684-of an internet search of phrase 4103, in <figref idref="f0557">Figure 41F</figref>. The device detects a tap gesture, including contact 4120 in <figref idref="f0558">Figure 41G</figref>, on movie preview 3670. In response, the device posts movie preview 3670 to the messaging session, displaying movie preview 3670 in conversation transcript 3503 in <figref idref="f0559">Figure 41H</figref>.

0890<figref idref="f0560 f0563">Figures 42A-42D</figref> are flow diagrams illustrating a method 4200 of capturing and posting digital images within a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.

0891As described below, the method 700 provides an intuitive way to capture and post digital images within a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when capturing and posting digital images within a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to capture and post digital images within a messaging application faster and more efficiently conserves power and increases the time between battery charges.

0892The device displays (4202) a messaging user interface (e.g., of a messaging application) on the display (e.g., user interface 3500 on touch screen 112 in <figref idref="f0234">Figure 35A</figref>), the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display; e.g., conversation transcript 3503 in <figref idref="f0234">Figure 35A</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a keyboard (e.g., displayed in a second area of the display; e.g., keyboard 3501 in <figref idref="f0234">Figure 35A</figref>), a message-input area (e.g., area 3502 in <figref idref="f0234">Figure 35A</figref>), and a digital image affordance (e.g., affordance 3504 in <figref idref="f0234">Figure 35A</figref>).

0893While displaying the messaging user interface, the device detects (4204) an input that activates the digital image affordance (e.g., for an electronic device with a touch sensitive display, detecting a tap gesture on the digital image affordance). For example, in <figref idref="f0235">Figure 35B</figref>, device 100-1 detects an input including contact 3512 on digital image affordance 3504.

0894In response to detecting the input that activates the digital image affordance, the device replaces (4206) display of the keyboard with display of a plurality of digital images, the plurality of digital images including one or more digital images stored in the memory and a live preview image from the digital camera. For example, responsive to detecting a tap gesture including contact 3512 in <figref idref="f0235">Figure 35B</figref>, the device replaces digital keyboard 3501 in <figref idref="f0235">Figure 35B</figref> with digital image tray 3806 including live preview image 3514 and previously captured digital images 3518.

0895In some embodiments, the messaging user interface is not displaying a digital keyboard prior to detecting activation of the digital image affordance (e.g., the conversation transcript is maximized and includes display of the digital image affordance). For example, in <figref idref="f0429">Figure 38B</figref>, messaging user interface 3500 is displaying a full-screen version of conversation transcript 3700 when an input including contact 3804 is detected at digital image affordance 3804. In response, the device shrinks display of conversation transcript 3700 to accommodate display of digital image tray 3806 in <figref idref="f0430">Figure 38C</figref>.

0896In some embodiments, replacing display of the keyboard includes displaying the plurality of digital images over the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the plurality of digital images where the keyboard had been displayed (e.g., as in <figref idref="f0235 f0236">Figure 35B-35C</figref>).

0897In some embodiments, the plurality of digital images is a scrollable array of digital images. For example, in <figref idref="f0249 f0250">Figures 35P-35Q</figref>, a drag gesture including movement 3538 of contact 3536 from position 3536-a in <figref idref="f0249">Figure 35P</figref> to position 3536-b in <figref idref="f0250">Figure 35Q</figref> scrolls digital image tray to the left, revealing additional previously captured digital images 3518-6 and 3519-7.

0898In some embodiments, the plurality of digital images includes a recently shared image, a recently received image, an image including a participant in the conversation (e.g., as identified by facial recognition), a real-time image from a forward-facing digital camera in the device, or a real-time image from a backwards-facing digital camera in the device.}

0899In some embodiments, the one or more digital images stored in the memory, and displayed in response to detecting the input that activates the digital image affordance, consist (4208) of digital images captured (and or posted) during the messaging session.

0900The device detects (4210) an input that selects the live image displayed within the plurality of digital images (e.g., for an electronic device with a touch sensitive display, detecting a tap gesture on the live image). For example, in <figref idref="f0237">Figure 35D</figref>, contact 3512 is detected on live preview image 3514 (e.g., on image capture affordance 3516 displayed over live preview image 3514).

0901In response to detecting that input that selects the live image, the device captures (4212) a digital image with the digital camera, while maintaining display of the conversation transcript. For example, in response to detecting an input that includes contact 3512 in <figref idref="f0237">Figure 35D</figref>, electronic device 100-1 captures digital image 3518-5, displayed in message-input area 3502 in <figref idref="f0238">Figure 35E</figref>.

0902In some embodiments, after capturing the digital image, the device displays (4214) the digital image captured by the digital camera in the conversation transcript and transmits a representation of the captured digital image to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the representation of the captured digital image in a conversation transcript that corresponds to the messaging session. For example, device 100-1 detects an input including contact 3522 on message-content posting affordance 3520 in <figref idref="f0239">Figure 35F</figref> and, in response, displays captured digital image 3520 in conversation transcript 3503 in <figref idref="f0240">Figure 35G</figref>. Device 100-1 also transmits a representation of digital image 3518-5 to other electronic device associated with other users of the messaging session, for example, "Abe."

0903In some embodiments, the captured image is automatically posted to the messaging session upon selection of the live image. For example, in response to detecting a deep press gesture including contact 3524 in <figref idref="f0241 f0240">Figures 35H-35G</figref>, device 100-1 automatically posts captured digital image 3518-5 to the messaging session, as displayed in conversation transcript 3503 in <figref idref="f0242">Figure 35I</figref>. In some embodiments, the device detects an input (e.g., a tap, press, deep press, double tap, multi-finger tap, long-press, or input including movement of a contact) and dependent upon the type of input, the device will either place the captured digital image in the message-input area or post it directly to the messaging session (e.g., display it in the conversation transcript). For example, <figref idref="f0236 f0242">Figures 35C-35I</figref> illustrate an exemplary embodiment where a tap gesture causes the device to place the captured image in the message-input area (e.g., as in <figref idref="f0237 f0239">Figures 35D-35F</figref>) and a deep press (or multi-finger input) causes the device to post the image directly to the messaging session (e.g., as in <figref idref="f0241 f0242">Figures 35H-35I</figref>).

0904In some embodiments, the captured image is displayed in the message input area and the user posts the image to the messaging session (e.g., by activating a send icon with a tap gesture). For example, activation of message-content posting affordance 3520 in <figref idref="f0239">Figure 35F</figref> causes the device to post the captured image to the messaging session, as displayed in messaging transcript 3503 in <figref idref="f0240">Figure 35G</figref>.

0905In some embodiments, prior to displaying the digital image captured by the digital camera in the conversation transcript (or any previously captured image) and transmitting a representation of the captured image, the device displays the digital image captured by the digital camera (or any previously captured image) in the message input area (e.g., as illustrated in <figref idref="f0255">Figure 35V</figref>). While displaying the digital image captured by the digital camera (or any previously captured digital image) in the message input area, the device detects an input that activates an image editing mode (e.g., contact 3546 in <figref idref="f0256">Figure 35W</figref>). In response to detecting the input that activates the image editing mode, the device replaces display of the messaging user interface with display of a digital photo editing user interface (e.g., user interface 3509 in <figref idref="f0257">Figure 35X</figref>), wherein the digital image captured by the digital camera (or any previously captured digital image) is displayed in the digital photo editing user interface (e.g., digital image 3518-4 in <figref idref="f0257">Figure 35X</figref>). While displaying the digital photo editing mode, the device detects an input that edits the digital photo captured by the digital camera (or any previously captured digital image). For example, inputs causing device 100-1 to draw mustache 3562 in <figref idref="f0259">Figure 35Z</figref>, place magnification loupe 3566 in <figref idref="f0261">Figure 35AB</figref>, configure magnification loupe 3566 in <figref idref="f0455 f0459">Figures 35AB-AF</figref>, type "Senor Snowman" 3578 in <figref idref="f0267">Figure 35AH</figref>, or add handwriting 3582 in <figref idref="f0269">Figure 35AJ</figref>. In response to detecting the input that edits the digital photo captured by the digital camera (or any previously captured digital image), the device edits (4216) the digital image captured by the digital camera (e.g., draws on, magnifies, types on, hand writes on, as described above). After editing the digital image captured by the digital camera, the device detects an input terminating the digital image editing mode (e.g., contact 3586 in <figref idref="f0270">Figure 35AK</figref>). In response to detecting the input terminating the digital image editing mode, the device displays the edited digital image captured by the digital camera (or any previously captured digital image) in the message input area (e.g., as illustrated in <figref idref="f0271">Figure 35AL</figref>.

0906In some embodiments, in response to detecting the input terminating the digital image editing mode, the device displays the edited digital image captured by the digital camera in the conversation transcript and sends a representation of the edited image to at least one other electronic device corresponding to another user included in the messaging session.

0907In some embodiments, any digital image (e.g., any of previously captured digital images 3518) can be edited from the messenger application and then posted to a messaging session, in accordance with the description above.

0908In some embodiments, in response to detecting the input that selects the live preview image, and after capturing the digital image, the device displays the digital image in the message-input area (e.g., digital image 3518-5 displayed in message-input area 3502 in <figref idref="f0244">Figure 35K</figref>). While displaying the digital image in the message-input area, the device detects input of a message in the message input area (e.g., a text message, such as message 3530 in <figref idref="f0246">Figure 35M</figref>). After detecting input of the message in the message-input area, the device detects an input that corresponds to a request to post contents of the message-input area to the messaging session (e.g., detecting a tap gesture on a send icon, such as contact 3532 in <figref idref="f0247">Figure 35N</figref>), the contents including the digital image and the message. In response to detecting the input that corresponds to the request to post the contents of the message-input area to the messaging session, the device displays the digital image in the conversation transcript (e.g., digital image 3518-5 in conversation transcript 3503 in <figref idref="f0248">Figure 35O</figref>), and the device displays (4218) the message (e.g., within a message region) in the conversation transcript, wherein the message (e.g., the message region) partially overlaps the digital image in the conversation transcript. For example, message 3534 partially overlaps with digital image 3518-5 in conversation transcript 3503 in <figref idref="f0248">Figure 35O</figref>. The device also transmits a representation of the digital image and the message to one or more electronic devices that correspond to the at least one other user included in the messaging session (e.g., "Abe" in <figref idref="f0248">Figure 35O</figref>), wherein the one or more electronic devices display the representation of the digital image and the message (e.g., the message region) in a conversation transcript corresponding to the messaging session, wherein the message (e.g., the message region) partially overlaps the representation of the digital image in the conversation transcript corresponding to the messaging session.

0909In some embodiments, in response to detecting the input that selects the live image, in accordance with a determination that the input that selects the live image meets one or more input-area-display criteria (e.g., one or more criteria based on the motion, timing, and/or intensity of a contact in the input), the device displays (4220) the digital image captured by the digital camera in the message input area (e.g., as illustrated in <figref idref="f0237 f0238">Figures 35D-35E</figref>, where the input-area-display criteria are met by a tap gesture including contact 3512), and in accordance with a determination that the input that selects the live image meets one or more transcript-area-display criteria (e.g., one or more criteria based on the motion, timing, and/or intensity of a contact in the input, which are distinct from the input-area-display criteria), the device displays the digital image captured by the digital camera in the conversation transcript and sends instructions, to one or more electronic devices that correspond to the at least one other user included in the messaging session, to display the digital image captured by the digital camera in a conversation transcript corresponding to the messaging session (e.g., as illustrated in <figref idref="f0241 f0242">Figures 35H-35I</figref>, where the transcript-area-display criteria are met by a press gesture including contact 3524).

0910In some embodiments, the electronic device includes one or more sensors configured to detect intensities of contacts on the touch-sensitive surface. Detecting the input that selects the live image displayed within the plurality of digital images includes that the device detects (4222) a first contact at a location on the touch-sensitive surface that corresponds to display of the live image on the display. The one or more transcript-area-display criteria require that a characteristic intensity of the first contact on the touch-sensitive surface meet a respective intensity threshold in order for the transcript-area-display criteria to be met (e.g., transcript-area-display criteria are met in <figref idref="f0242">Figure 35I</figref> because a characteristic intensity of contact 3524 meets a predefined intensity threshold (e.g., IT_L or IT_D)). The one or more input-area-display criteria do not require that the characteristic intensity of the contact on the touch-sensitive surface meet the respective intensity threshold in order for the selection criteria to be met (e.g., input-area-display criteria are met in Figure in <figref idref="f0237 f0238">Figures 35D-35E</figref> even though a characteristic intensity of contact 3512 did not meet a predefined intensity threshold (e.g., IT_L or IT_D)).

0911In some embodiments, the input-area-display criteria are met when a characteristic intensity of the first contact is between a first intensity threshold and a second intensity threshold and the transcript-area-display criteria are met when a characteristic intensity of the first contact is between the second intensity threshold and a third intensity threshold. In some embodiments, the second intensity threshold is above the first intensity threshold and the third intensity threshold is above the second intensity threshold (e.g., tap to display the digital image in the message input area before posting the image to the messaging session and light press (or deep press) to post the digital image directly to the messaging session). In some embodiments, the second intensity threshold is below the first intensity threshold and the third intensity threshold is below the second intensity threshold (e.g., deep press) to display the digital image in the message input area before posting the image to the messaging session and tap to post the digital image directly to the messaging session).

0912In some embodiments, the one or more input-area-display criteria are met upon detection (4224) of a tap gesture on the touch-sensitive surface (e.g., a tap gesture including contact 3512 in <figref idref="f0237">Figure 35D</figref>).

0913In some embodiments, prior to detecting the input that selects the live preview image (or a previously captured digital image) displayed within the plurality of digital images, the device detects a first portion of a second input that includes detecting an increase in a characteristic intensity of a second contact, at a location that corresponds to display of a first digital image within the plurality of digital images above a preview-intensity threshold. For example, device 100-1 detects an input including contact 3540, which increases in intensity above a predefined intensity threshold (e.g., IT_L or IT_D) between <figref idref="f0251">Figure 35R</figref> and <figref idref="f0252">35S</figref>. In some embodiments, the first digital image is the live preview image (e.g., live preview image 3514). ISE, the first digital image is a previously acquired image (e.g., previously captured digital image 3518-4 in <figref idref="f0251">Figure 35R</figref>).

0914In response to detecting the first portion of the second input, the device increases (4226) the size of the first digital image. For example, in response to detecting the increase in intensity of contact 3540, device 100-1 displays enlarged preview 3507 of digital image 3518-4 in <figref idref="f0252">Figure 35S</figref>. In some embodiments, the size of the first digital image is increased dynamically in accordance with the increase in the characteristic intensity of the second contact. After increasing the size of the first digital image, detecting a second portion of the second input that includes detecting a decrease in the characteristic intensity of the second contact below the preview intensity threshold and, in response to detecting the second portion of the second input, decreasing the size of the first digital image. For example, device 100-1 detects a decrease in the intensity of contact 3540 between <figref idref="f0252">Figures 35S</figref> and <figref idref="f0253">35T</figref> and, in response, shrinks image 3518-4 back to its original size in the digital image tray in <figref idref="f0253">Figure 35T</figref>.

0915In some embodiments, the device detects a user input including a first swipe gesture that starts while a focus selector is at a first location in the messaging user interface that corresponds to a first digital image in the plurality of digital images, the first swipe gesture moving the focus selector in a first direction (e.g., detects a drag gesture by a contact on a touch-sensitive surface, such as a touch sensitive display, that starts at the first digital image and moves in a first direction (e.g., towards the edge of the display), or detects a swipe gesture by a contact on a touch-sensitive surface that starts while a cursor or other pointer is at the first digital image on the display and moves the pointer in a first direction on the display). For example, device 100-1 detects a swipe gesture to the left, including movement 3538 of contact 3536 from location 3536-a in <figref idref="f0249">Figure 35P</figref> to location 3536-b in <figref idref="f0250">Figure 35Q</figref>.

0916In response to detecting the first swipe gesture, the device scrolls display (4228) of the plurality of digital images in the first direction on the display, wherein the scrolling display includes ceasing to display digital images in the plurality of digital images that are scrolled off a first edge of the display and displaying new digital images in the plurality of digital images from a second (e.g., opposite) edge of the display (e.g., photos are scrolled off the display in the direction of the swipe gesture and new images are brought onto the display from the opposite edge of the display). For example, in <figref idref="f0250">Figure 35Q</figref>, device 100-1 moves digital image tray 3806 to the left, in accordance with movement 3538, creating the appearance that live preview image 3514 slides off of the left side of touch screen 112 and additional digital images 3518-6 and 3518-7 slide onto the display from the right side of touch screen 112, in <figref idref="f0250">Figure 35Q</figref>.

0917In some embodiments, the device detects a user input including a second swipe gesture that starts while a focus selector is at a first location in the messaging user interface that corresponds to a first digital image in the plurality of digital images, the first swipe gesture moving the focus selector in a second direction (e.g., opposite of the first direction; e.g., the device detects a drag gesture by a contact on a touch-sensitive surface, such as a touch sensitive display, that starts at the first digital image and moves in a second direction (e.g., towards an opposite edge of the display), or detects a swipe gesture by a contact on a touch-sensitive surface that starts while a cursor or other pointer is at the first digital image on the display and moves the pointer in a second direction on the display. For example, device 100-1 detects a swipe gesture to the right, including movement of contact 3812 from position 3812-a in <figref idref="f0433">Figure 38F</figref> to position 3828-b in <figref idref="f0434">Figure 38G</figref>.

0918In response to detecting the second swipe gesture, the device displays (4230) (e.g., reveals from a first edge of the display) a first affordance for the digital camera and a second affordance for a photo library. For example, full-screen camera affordance 3816 and photo library affordance 3818 are revealed in digital image tray 3806, from the left side of touch screen 112, in response to detecting the swipe gesture including movement 3814 of contact 3812 <figref idref="f0434">Figure 38G</figref>.

0919In some embodiments, while displaying the first affordance for the digital camera (e.g., camera affordance 3816 in <figref idref="f0435">Figure 38H</figref>), the device detects an input that activates the first affordance for the digital camera (e.g., contact 3820 in <figref idref="f0435">Figure 38H</figref>) and, in response to detecting the input that activates the first affordance for the digital camera, the device displays (4232) a user interface for the digital camera over at least a portion of the messaging user interface (e.g., user interface 3822 displayed in <figref idref="f0436">Figure 38I</figref>). In some embodiments, the interactive application user interface entirely replaces display of the messaging user interface (e.g., as in <figref idref="f0436">Figure 38I</figref>).

0920In some embodiments, while displaying the second affordance for the photo library (affordance 3818 in <figref idref="f0442">Figure 38O</figref>), the device detects an input that activates the second affordance for the photo library (e.g., contact 3830 in <figref idref="f0442">Figure 38O</figref>) and, in response to detecting the input that activates the second affordance for the photo library, the device ceases (4234) to display the plurality of digital images including one or more digital images stored in the memory and a live preview image from the digital camera and displays a plurality of digital images from a digital photo library (e.g., a photo library stored on the electronic device or a photo library stored remotely). For example, in response to detecting an input including contact 3830 in <figref idref="f0442">Figure 38O</figref>, device 100-1 replaces display of messenger user interface 3500 in <figref idref="f0442">Figure 38O</figref> with photo library user interface 3832 in <figref idref="f0443">Figure 38P</figref>.

0921While displaying the plurality of digital images from the digital photo library, the device detects an input that selects a digital image in the plurality of digital images from the digital photo library and in response to detecting the input that selects the digital image from the digital photo library, the device displays the digital image from the digital photo library in the conversation transcript. In some embodiments, the digital image is automatically posted to the messaging session upon selection of the image. In some embodiments, the digital image is displayed in the message input area and the user posts the image to the messaging session (e.g., by activating a send icon with a tap gesture). The device also transmit a representation of the digital image from the digital photo library to one or more electronic devices that correspond to the at least one other user included in the messaging session (e.g., "Abe"), where the one or more electronic devices display the representation of the digital image from the digital photo library in a conversation transcript that corresponds to the messaging session.

The processing unit 4312 is further configured to, in response to detecting the first portion of the second input, increase the size of the first digital image. The processing unit 4312 is further configured to, after increasing the size of the first digital image, detect (e.g., with detecting unit 4316) a second portion of the second input that includes detecting a decrease in the characteristic intensity of the second contact below the preview intensity threshold. The processing unit 4312 is further configured to, in response to detecting the second portion of the second input, decrease the size of the first digital image.

0933In some embodiments, the processing unit 4312 is configured to detect (e.g., with detecting unit 4316) a user input including a first swipe gesture that starts while a focus selector is at a first location in the messaging user interface that corresponds to a first digital image in the plurality of digital images, the first swipe gesture moving the focus selector in a first direction. The processing unit 4312 is further configured to, in response to detecting the first swipe gesture, scroll display (e.g., with scrolling unit 4324) of the plurality of digital images in the first direction on the display unit, wherein the scrolling display includes ceasing to display digital images in the plurality of digital images that are scrolled off a first edge of the display unit and displaying new digital images in the plurality of digital images from a second edge of the display unit.

0934In some embodiments, the processing unit 4312 is configured to detect (e.g., with detecting unit 4316) a user input including a second swipe gesture that starts while a focus selector is at a first location in the messaging user interface that corresponds to a first digital image in the plurality of digital images, the first swipe gesture moving the focus selector in a second direction. The processing unit 4312 is further configured to, in response to detecting the second swipe gesture, display (e.g., with display enabling unit 4314) a first affordance for the digital camera unit 4308 and a second affordance for a photo library.

0935In some embodiments, the processing unit 4312 is configured to, while displaying the first affordance for the digital camera unit 4308, detect (e.g., with detecting unit 4316) an input that activates the first affordance for the digital camera unit 4308. The processing unit 4312 is further configured to, in response to detecting the input that activates the first affordance for the digital camera unit 4308, display (e.g., with display enabling unit 4314) a user interface for the digital camera unit 4308 over at least a portion of the messaging user interface.

0936In some embodiments, the processing unit 4312 is configured to, while displaying the second affordance for the photo library, detect (e.g., with detecting unit 4316) an input that activates the second affordance for the photo library. The processing unit 4312 is further configured to, in response to detecting the input that activates the second affordance for the photo library, cease to display (e.g., with display enabling unit 4314) the plurality of digital images including one or more digital images stored in the memory unit 4310 and a live preview image from the digital camera unit 4308 and display a plurality of digital images from a digital photo library. The processing unit 4312 is further configured to, while displaying the plurality of digital images from the digital photo library, detect (e.g., with detecting unit 4316) an input that selects a digital image in the plurality of digital images from the digital photo library. The processing unit 4312 is further configured to, in response to detecting the input that selects the digital image from the digital photo library, display (e.g., with display enabling unit 4314) the digital image from the digital photo library in the conversation transcript, and transmit (e.g., with transmitting unit 4320) a representation of the digital image from the digital photo library to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the representation of the digital image from the digital photo library in a conversation transcript that corresponds to the messaging session.

0937In some embodiments, the one or more digital images stored in the memory unit 4310, and displayed in response to detecting the input that activates the digital image affordance, consist of digital images captured during the messaging session.

0938The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

0939The operations described above with reference to <figref idref="f0560 f0563">Figures 42A-42D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0564">Figure 43</figref>. For example, detection operations 4204 and 4210 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0940<figref idref="f0565 f0568">Figures 44A-44D</figref> are flow diagrams illustrating a method 4400 of searching for and sharing multimedia content within a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 4400 are, optionally, combined and/or the order of some operations is, optionally, changed.

0941As described below, the method 700 provides an intuitive way to search for and share multimedia content within a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when searching for and sharing multimedia content within a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to search for and share multimedia content within a messaging application faster and more efficiently conserves power and increases the time between battery charges.

0942The device displays (4402) a messaging user interface (e.g., of a messaging application, for example, user interface 3500 in <figref idref="f0276">Figures 36A</figref> and <figref idref="f0300">36Y</figref>) on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display, for example, conversation transcript 3503 in <figref idref="f0276">Figures 36A</figref> and <figref idref="f0300">36Y</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device, for example "Abe," represented by avatar 3510 in <figref idref="f0276">Figures 36A</figref> and <figref idref="f0300">36Y</figref>), and a search affordance (e.g., search affordance 3602 in <figref idref="f0276">Figure 36A</figref> or search launch icon 3607 in <figref idref="f0300">Figure 36Y</figref>). In some embodiments, the messaging user interface includes a message input area that is configured to display content ready to be posted to the messaging session (e.g., message-content input area 3502 in <figref idref="f0276">Figures 36A</figref> and <figref idref="f0300">36Y</figref>). In some embodiments, the messaging user interface includes a keyboard, e.g., displayed in a second area of the display (e.g., digital keyboard 3501 in <figref idref="f0276">Figure 36A</figref>).

0943In some embodiments, the search affordance is displayed as a launch icon for a search application in a plurality of launch icons for interactive applications within the messaging user interface (e.g., search launch icon 3607 is displayed in application selection tray 3654 with launch icons 3601, 3603, 3605, 3609, 3611, 3613, and 3615). In some embodiments, the search affordance is a search application launch icon (4404) that is displayed with a plurality of launch icons for interactive applications within the messaging application.

0944In some embodiments, prior to displaying the plurality of launch icons for interactive applications in the messaging user interface, the messaging user interface included the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a keyboard (e.g., displayed in a second area of the display), a message-input area, and an application affordance. For example, in <figref idref="f0298">Figure 36W</figref>, user interface 3500 includes conversation transcript 3503, keyboard 3501, message-content input area 3502, and application affordance 3508. The device detects a user input that activates the application affordance (e.g., an input including contact 3652 in <figref idref="f0299">Figure 36X</figref>) and, in response to detecting the user input that activates the application affordance, the device replaces (4406) display of the keyboard with display of the plurality of launch icons for interactive applications (e.g., application selection tray 3654 in <figref idref="f0300">Figure 36Y</figref> replaces digital keyboard 3501 in <figref idref="f0299">Figure 36X</figref>).

0945In some embodiments, the messaging user interface is not displaying a digital keyboard prior to detection of the application affordance (e.g., the conversation transcript is maximized and includes display of the application affordance). For example, as illustrated in <figref idref="f0463 f0466">Figures 38AJ-38AM</figref>.

0946In some embodiments, replacing display of the keyboard includes displaying the plurality of launch icons for interactive applications over the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the plurality of launch icons for interactive applications where the keyboard had been displayed.

0947While displaying the messaging user interface, the device detects (4408) an input that activates the search affordance. For example an input including contact 3602 on search affordance 3602 in <figref idref="f0277">Figure 36B</figref> or an input including contact 3656 on search application launch icon 3607 in <figref idref="f0301">Figure 36Z</figref>.

0948In response to detecting the input that activates the search affordance (4410), the device ceases to display the messaging user interface and displays a search user interface, the search user interface including a search field and a plurality of categorized content items, wherein the plurality of categorized content items includes at least a content item stored on the electronic device and a content item from the Internet. For example, in response to activating search application launch icon 3607 in <figref idref="f0301">Figure 36Z</figref>, device 3500 ceases displaying messenger user interface 3500 and displays search user interface 3658 in <figref idref="f0302">Figure 36AA</figref>, including content items 3662, 3664, 3666, 3668, 3670, 3672 categorized as suggested content for posting (e.g., the current location of the device 3662, a news article 3664 being accessed from the internet, a digital recording 3666 playing on the device) and recently shared content (e.g., a news article 3668 accessed from the internet, a movie trailer 3670 accessed from the internet, and a digital image 3672).

0949In some embodiments, the content items include suggested content, such as content open on the device, content recently accessed on the device (e.g., content 3662, 3664, and 3666 in <figref idref="f0302">Figure 36AA</figref>), content related to the messaging session (e.g., content identified as associated with any of the users of the messaging session), web content related to content open or recently opened on the device (e.g., content 3664, 3668, and 3670 in <figref idref="f0302">Figure 36AA</figref>), web content related to the messaging session, content related to the location of the device (e.g., content 3662 in <figref idref="f0302">Figure 36AA</figref>), recently shared content (e.g., content 3668, 3670, and 3672 in <figref idref="f0302">Figure 36AA</figref>), recently received content, and/or content that is trending (e.g., in a social networking application; e.g., content 3678, 3680, 3668, and 3669 in <figref idref="f0306">Figure 36AE</figref>). ISE, the content items are related to an input in the search field (e.g., content 3664, 3678, 3680, 3670, 3682, and 3684 are results from a search of the word "Meteorites" in <figref idref="f0281">Figure 36F</figref>). In some embodiments, the content includes rich links, music, application links, and/or web links. In some embodiments, the plurality of categorized content items is displayed as a scrollable list of content items, arranged by content categories (e.g., additional content in <figref idref="f0308 f0283">Figures 36AG-36H</figref> is accessed by scrolling the search results to the left).

0950While displaying the search user interface, the device detects an input that selects a first content item in the plurality of categorized content items (e.g., for an electronic device with a touch sensitive display, detecting a tap gesture on the first content item). For example, device 100-1 detects a tap gesture including contact 3674 on movie trailer 3670 in <figref idref="f0303">Figure 36AB</figref> and a tap gesture including contact 3690 on movie trailer 3684 in <figref idref="f0310">Figure 36AI</figref>.

0951After detecting the input that selects the first content item in the plurality of categorized content items (4414), the device ceases to display the searching user interface and displays the first content item in the conversation transcript within the messaging user interface. For example, in response to detecting a tap gesture including contact 3674 on movie trailer 3670 in <figref idref="f0303">Figure 36AB</figref>, device 100-1 replaces display of search user interface 3658 with display of messaging user interface 3500 in <figref idref="f0304">Figure 36AC</figref>. Similarly, in response to detecting a tap gesture including contact 3690 on movie trailer 3684 in <figref idref="f0310">Figure 36AI</figref>, device 100-1 replaces display of search user interface 3658 with display of messaging user interface 3500 in <figref idref="f0311">Figure 36AJ</figref>.

0952The device also transmits (4416) the first content item (e.g., information relating to the first content item) to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session (e.g., "Abe"), where the one or more electronic devices display the first content item in a conversation transcript that corresponds to the messaging session.

0953In some embodiments, detecting the input that selects the first content item includes: detecting a first input while a focus selector is over the first content item, and displaying the selected first content item in a message-input area. For example, as illustrated in <figref idref="f0310">Figures 36AI-36AJ</figref>. In some embodiments, while displaying the selected content item in the message-input area, the device detects a second input to post the contents of the message-input area to the conversation transcript of the messaging session. For example, device 100-1 detects a tap input including contact 3696 on send affordance 3520 in <figref idref="f0312">Figure 36AK</figref>, and posts movie trailer 3684 to the messaging session, as displayed in conversation transcript 3503 in <figref idref="f0313">Figure 36AL</figref>.

0954In some embodiments, the first content item is displayed in the conversation transcript of the messaging session (e.g., is directly posted to the messaging session) in response to detecting the input that selects the first content item. For example, in response to detecting a tap gesture including contact 3674 on movie trailer 3670 in <figref idref="f0303">Figure 36AB</figref>, device 100-1 posts the movie trailer directly to the messaging session, as displayed in conversation transcript 3503 in <figref idref="f0304">Figure 36AC</figref>.

0955In some embodiments, while displaying the search user interface, and prior to detecting the input that selects the first content item in the plurality of categorized content items, the device (4418) receives input of a query in the search field and, in response to receiving input of the query in the search field, updates the displayed plurality of categorized content items to display content items that satisfy the query. For example, while displaying search user interface 3658 in <figref idref="f0305">Figure 36AD</figref>, device 100-1 receives input of search query "Meterorites" in search field 3660 and, in response, displays search user interface 3661 with updated content items satisfying the query in <figref idref="f0307">Figure 36AF</figref>.

0956In some embodiments, in response to detecting the input that selects the first content item, the device (4420) displays the first content item in the message-input area, while displaying the first content item in the message-input area, receiving input of a message in the message input area (e.g., a text message). After receiving input of the message in the message-input area, the device detects an input that corresponds to a request to post the contents of the message-input area to the messaging session (e.g., detecting a tap gesture on a send icon), the contents including the first content item and the message. In response to detecting the input that corresponds to the request to post the contents of the message-input area to the messaging session, the device displays the first content item in the conversation transcript, displays the message (e.g., within a message region) in the conversation transcript, wherein the message (e.g., the message region) partially overlaps the first content item in the conversation transcript, and transmits the first content item and the message to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the first content item and the message in a conversation transcript corresponding to the messaging session, wherein the message (e.g., the message region) partially overlaps the first content item in the conversation transcript corresponding to the messaging session.

0957In some embodiments, in response to detecting the input that selects the first content item, the device (4422): in accordance with a determination that the input that selects the first content item meets one or more input-area-display criteria (e.g., one or more criteria based on the motion, timing, and/or intensity of a contact in the input), displays the first content item in the message input area (e.g., as illustrated in <figref idref="f0310 f0311">Figures 36AI-36AJ</figref>), and in accordance with a determination that the input that selects the first content item meets one or more transcript-area-display criteria (e.g., one or more criteria based on the motion, timing, and/or intensity of a contact in the input, which are distinct from the input-area-display criteria) displays the first content item in the conversation transcript (e.g., as illustrated in <figref idref="f0303 f0304">Figures 36AB-36AC</figref>) and transmits the first content item to one or more electronic devices that correspond to the at least one other user included in the messaging session, where the one or more electronic devices display the first content item in a conversation transcript corresponding to the messaging session.

0958In some embodiments, the electronic device includes one or more sensors configured to detect intensities of contacts on the touch-sensitive surface. Detecting the input that selects the first content item in the plurality of content items includes detecting a first contact at a location on the touch-sensitive surface that corresponds to display of the first content item on the display. The one or more transcript-area-display criteria require that a characteristic intensity of the first contact on the touch-sensitive surface meet a respective intensity threshold in order for the transcript-area-display criteria to be met (e.g., transcript-area-display criteria are met in <figref idref="f0261">Figure 35AB</figref> if a characteristic intensity of contact 3674 meets a predefined intensity threshold (e.g., IT_L or IT_D)). The one or more input -area-display criteria do not require that the characteristic intensity of the contact on the touch-sensitive surface meet the respective intensity threshold in order for the selection criteria to be met (e.g., input-area-display criteria are met in Figure in <figref idref="f0310 f0311">Figures 36AI-36AJ</figref> even if a characteristic intensity of contact 3690 does not meet a predefined intensity threshold (e.g., IT_L or IT_D)).

0959In some embodiments, (4424) input-area-display criteria are met when a characteristic intensity of the first contact is between a first intensity threshold and a second intensity threshold and the transcript-area-display criteria are met when a characteristic intensity of the first contact is between the second intensity threshold and a third intensity threshold. In some embodiments, the second intensity threshold is above the first intensity threshold and the third intensity threshold is above the second intensity threshold (e.g., tap to display the content item in the message input area before posting the content item to the messaging session and light press (or deep press) to post the first content item directly to the messaging session). In some embodiments, the second intensity threshold is below the first intensity threshold and the third intensity threshold is below the second intensity threshold (e.g., light press (or deep press) to display the content item in the message input area before posting the content item to the messaging session and tap to post the first content item directly to the messaging session).

0960In some embodiments, the one or more input-area-display criteria are met (2426) upon detection of a tap gesture on the touch-sensitive surface (e.g., a tap gesture including contact 3690 in <figref idref="f0310">Figure 36AI</figref>).

0961In some embodiments, while displaying the first content item in the conversation transcript within the messaging user interface, the device (4428) detects a first input by a first contact at a location that corresponds to the first content item and, in response to detecting the first input, in accordance with a determination that the first contact meets one or more expansion criteria (e.g., a tap, deep press, or long press gesture), the device displays an expanded version of content associated with the first content item. For example, device 100-1 detects a tap gesture, including contact 3636, on news article 3634 displayed in conversation transcript 3503, in <figref idref="f0291">Figure 36P</figref>. In response, device 100-1 accesses the web page associated with the news article in area 3638, displayed over portions of search tray 3629 and conversation transcript 3503, in <figref idref="f0292">Figure 36Q</figref>. Device 100-1 then displays more of the news article from the web site, in area 3638, responsive to detecting a swipe gesture, including movement 3642 of contact 3640 from position 3640-a in <figref idref="f0293">Figure 36R</figref> to position 3640-b in <figref idref="f0294">Figure 36S</figref>.

0962In some embodiments, the expanded version of the content is navigation to a website, display of an application preview platter displaying more content than the first content item displayed in the conversation transcript, display of a video, or opening of an interactive application within the messaging application.

0963In some embodiments, the device detects (4430), in the conversation transcript, a word or phrase associated with additional content stored on the electronic device and additional content available on the Internet (e.g., business/restaurant info, music info, movie info; insert boilerplate from Siri/ontology applications). For example, device 100-1 device recognizes phrase 4103 ("Astron Omer") as the name of an actor about whom information is available on the internet. In response, the device displays highlighting 4116 of phrase 4103 in <figref idref="f0555">Figure 41D</figref>, prompting the user to select the phrase. The device then detects a tap gesture, including contact 4118, on phrase 4103 in <figref idref="f0556">Figure 41E</figref>. In response, the device displays search user interface 3661 displaying categorized results-new articles 3664, 3678, and 3680 and movie previews 3670, 3682, and 3684-of an internet search of phrase 4103, in <figref idref="f0557">Figure 41F</figref>. The device detects a tap gesture, including contact 4120 in <figref idref="f0558">Figure 41G</figref>, on movie preview 3670. In response, the device posts movie preview 3670 to the messaging session, displaying movie preview 3670 in conversation transcript 3503 in <figref idref="f0559">Figure 41H</figref>. In some embodiments, detecting the word or phrase is done in response to detecting the input that activates the search affordance. The plurality of categorized content items displayed in the search user interface includes a content item stored on the electronic device associated with the word or phrase detected in the conversation transcript.

0964In some embodiments, the device detects (4432), in the conversation transcript, a word or phrase associated with additional content stored on the electronic device and additional content available on the Internet (e.g., business/restaurant info, music info, movie info; insert boilerplate from Siri/ontology applications). In some embodiments, detecting the word or phrase is done in in response to detecting the input that activates the search affordance. The plurality of categorized content items displayed in the search user interface includes content item from the Internet associated with the word or phrase detected in the conversation transcript.

The processing unit 4506 is further configured to, while displaying the messaging user interface, detect (e.g., with detecting unit 4510) an input that activates the search affordance. The processing unit 4506 is further configured to, in response to detecting the input that activates the search affordance: cease to display (e.g., with display enabling unit 4508) the messaging user interface, and display a search user interface, the search user interface including a search field and a plurality of categorized content items, wherein the plurality of categorized content items includes at least a content item stored on the electronic device 4500 and a content item from the Internet. The processing unit 4506 is further configured to, while displaying the search user interface, detect (e.g., with detecting unit 4510) an input that selects a first content item in the plurality of categorized content items. The processing unit 4506 is further configured to, after detecting the input that selects the first content item in the plurality of categorized content items: cease to display (e.g., with display enabling unit 4508) the searching user interface, display the first content item in the conversation transcript within the messaging user interface, and transmit (e.g., with transmitting unit 4512) the first content item to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the first content item in a conversation transcript that corresponds to the messaging session.

0969In some embodiments, the processing unit 4506 is configured to, while displaying the search user interface, and prior to detecting the input that selects the first content item in the plurality of categorized content items, receive input (e.g., with receiving input unit 4518) of a query in the search field. The processing unit 4506 is further configured to, in response to receiving input of the query in the search field, update (e.g., with updating unit 4516) the displayed plurality of categorized content items to display content items that satisfy the query.

0970In some embodiments, the processing unit 4506 is configured to, in response to detecting the input that selects the first content item, display (e.g., with display enabling unit 4508) the first content item in the message-input area. The processing unit 4506 is further configured to, while displaying the first content item in the message-input area, receive input (e.g., with receiving input unit 4518) of a message in the message input area. The processing unit 4506 is further configured to, after receiving input of the message in the message-input area, detect an input that corresponds to a request to post the contents of the message-input area to the messaging session, the contents including the first content item and the message. The processing unit 4506 is further configured to, in response to detecting the input that corresponds to the request to post the contents of the message-input area to the messaging session, display (e.g., with display enabling unit 4508) the first content item in the conversation transcript, display (e.g., with display enabling unit 4508) the message in the conversation transcript, wherein the message partially overlaps the first content item in the conversation transcript, and transmit (e.g., with transmitting unit 4512) the first content item and the message to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the first content item and the message in a conversation transcript corresponding to the messaging session, wherein the message partially overlaps the first content item in the conversation transcript corresponding to the messaging session.

0971In some embodiments, the processing unit 4506 is configured to, in response to detecting the input that selects the first content item, in accordance with a determination that the input that selects the first content item meets one or more input-area-display criteria, display (e.g., with display enabling unit 4508) the first content item in the message input area. The processing unit 4506 is further configured to, in accordance with a determination that the input that selects the first content item meets one or more transcript-area-display criteria: display (e.g., with display enabling unit 4508) the first content item in the conversation transcript, and transmit (e.g., with transmitting unit 4512) the first content item to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the first content item in a conversation transcript corresponding to the messaging session.

0972In some embodiments, the electronic device 4500 includes one or more sensors units configured to detect intensities of contacts on the touch-sensitive surface unit 4504. In some embodiments, detecting the input that selects the first content item in the plurality of content items includes detecting a first contact at a location on the touch-sensitive surface unit 4504 that corresponds to display of the first content item on the display unit 4502. In some embodiments, the one or more transcript-area-display criteria require that a characteristic intensity of the first contact on the touch-sensitive surface unit 4504 meet a respective intensity threshold in order for the transcript-area-display criteria to be met. In some embodiments, the one or more input-area-display criteria do not require that the characteristic intensity of the contact on the touch-sensitive surface unit 4504 meet the respective intensity threshold in order for the selection criteria to be met.

0973In some embodiments, the one or more input-area-display criteria are met upon detection of a tap gesture on the touch-sensitive surface unit 4504.

0974In some embodiments, the processing unit 4506 is configured to, while displaying the first content item in the conversation transcript within the messaging user interface, detect (e.g., with detecting unit 4510) a first input by a first contact at a location that corresponds to the first content item. The processing unit 4506 is further configured to, in response to detecting the first input, in accordance with a determination that the first contact meets one or more expansion criteria, display (e.g., with display enabling unit 4508) an expanded version of content associated with the first content item.

0975In some embodiments, the processing unit 4506 is configured to detect, in the conversation transcript, a word or phrase associated with additional content stored on the electronic device 4500 and additional content available on the Internet, wherein the plurality of categorized content items displayed in the search user interface includes a content item stored on the electronic device 4500 associated with the word or phrase detected in the conversation transcript.

0976In some embodiments, the processing unit 4506 is configured to, detect, in the conversation transcript, a word or phrase associated with additional content stored on the electronic device 4500 and additional content available on the Internet, wherein the plurality of categorized content items displayed in the search user interface includes content item from the Internet associated with the word or phrase detected in the conversation transcript.

0977In some embodiments, the search affordance is a search application launch icon that is displayed with a plurality of launch icons for interactive applications within the messaging application.

0978In some embodiments, the processing unit 4506 is configured to, prior to displaying the plurality of launch icons for interactive applications in the messaging user interface, the messaging user interface included the conversation transcript of the messaging session between a user of the electronic device 4500 and at least one other user, a keyboard, a message-input area, and an application affordance: detect (e.g., with detecting unit 4510) a user input that activates the application affordance. The processing unit 4506 is further configured to, in response to detecting the user input that activates the application affordance, replace display of the keyboard with display of the plurality of launch icons for interactive applications.

0979The operations described above with reference to <figref idref="f0565 f0568">Figures 44A-44D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0564">Figure 43</figref>. For example, detection operations 4408 and 4412 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

0980<figref idref="f0570 f0572">Figures 46A-46C</figref> are flow diagrams illustrating a method 4600 of adding an interactive application to a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.

0981As described below, the method 700 provides an intuitive way to add an interactive application to a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when adding an interactive application to a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to add an interactive application to a messaging application faster and more efficiently conserves power and increases the time between battery charges.

0982The device displays (4602) a messaging user interface of a messaging application (e.g., messaging user interface 3500 in <figref idref="f0470">Figure 38AQ</figref>) on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display, such as conversation transcript 3503 in <figref idref="f0470">Figure 38AQ</figref>) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), and an application affordance (e.g., application affordance 3508 in Figure AQ). In some embodiments, the messaging user interface includes a message input area that is configured to display content ready to be posted to the messaging session (e.g., message-input area 3502 in Figure AQ). In some embodiments, the messaging user interface includes a keyboard (e.g., digital keyboard 3501 in <figref idref="f0470">Figure 38AQ</figref>), e.g., displayed in a second area of the display.

0983While displaying the messaging user interface, the device detects (4604) an input that activates the application affordance. For example, a tap gesture including contact 3876 on application affordance 3508 in <figref idref="f0471">Figure 38AR</figref>.

0984In response to detecting the input that activates the application affordance (e.g., while maintaining display of the conversation transcript), the device concurrently displays (4606) a launch icon for an application store and a plurality of launch icons for interactive applications, where activation of a respective launch icon for an interactive application launches a corresponding application that is displayed within the messaging application. For example, in response to detecting the tap gesture including contact 3876 in <figref idref="f0471">Figure 38AR</figref>, device 100-1 displays application selection tray 3654, including launch icon 3601 for an application store and other launch icons for interactive applications-e.g., launch icon 3603 for a tic-tac-toe application, launch icon 3605 for a reservation application, launch icon 3611 for a live video-streaming application, and launch icon 3615 for a music application.

0985In some embodiments, the messaging user interface is not displaying a digital keyboard just prior to detecting the input that activates the application affordance (e.g., the conversation transcript is maximized and includes display of the application affordance or the keyboard is replaced by a user interface for an interactive application that is displayed within the messaging application). In some embodiments, the plurality of launch icons for interactive applications replaces display of the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the plurality of launch icons for interactive applications where the keyboard had been displayed.

0986In some embodiments, the interactive application is configured to perform (4608) a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, the application store application launched in response to activation of launch icon 3601 only allows download of applications operable within a messaging application. In contrast, a corresponding application store application (e.g., as launched from a home screen on the device outside of the messaging application) allows download of applications operable within a messaging application and applications operable outside of the messaging application.

0987In some embodiments, the interactive application launch icon displays (4610) an identifier for a corresponding application operated separate from the messaging application. For example, in <figref idref="f0472">Figure 38AS</figref>, application store launch icon 3601 includes a same or similar "A" logo as an application store application operated outside of the messaging application.

0988In some embodiments, the interactive application displays (4612) a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, the application store application launched in response to activation of launch icon 3601 only displays all downloadable applications that are operable within the messaging application. In contrast, a corresponding application store application (e.g., as launched from a home screen on the device outside of the messaging application) displays all downloadable applications operable within a messaging application and operable outside of the messaging application.

0989In some embodiments, the interactive application causes (4614) the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on application store launch icon 3601 in <figref idref="f0472">Figure 38AS</figref>, the device launches an application store application within the messaging application. In response to a second (e.g., different) input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on application store launch icon 3601 in <figref idref="f0472">Figure 38AS</figref>, the device launches an application store application outside of the messaging application.

0990In some embodiments, the interactive application is operated (4616) separately from a corresponding application operated separate from the messaging application. For example, the application store application launched in response to activation of launch icon 3601 may be operated when a corresponding application store application operated outside of the application in not running.

0991In some embodiments, the interactive application is operated (4618) in conjunction with a corresponding application operated separate from the messaging application. For example, the application store application launched in response to activation of launch icon 3601 may not be operated when a corresponding application store application operated outside of the application in not running.

0992In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage (4620) that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of applications downloaded using the application store application corresponding to launch icon 3601 are stored in a different portion of memory than records of applications downloaded using a corresponding application store application operated outside of the messaging application.

0993In some embodiments, the corresponding application operated separate from the messaging application is configured (4622) to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding application store application operated outside of the messaging application can access the records of applications downloaded using the application store application corresponding to launch icon 3601.

0994The device then detects (4624) an input that activates the launch icon for the application store. For example, device 100-1 detects a tap gesture including a contact on application store launch icon 3601 in <figref idref="f0472">Figure 38AS</figref>.

0995In response to detecting the input that activates the launch icon for the application store, the device (4626) ceases to display the messaging user interface and displays an application store user interface, including display of at least one interactive application available for download to the electronic device. For example, responsive to detecting a tap gesture including a contact on application store launch icon 3601 in <figref idref="f0446">Figure 38S</figref>, device 100-1 replaces display of messaging user interface 3500 with display of an application store user interface.

0996While displaying the application store user interface, the device detects (4628) an input that corresponds to a request to download a first interactive application that is not stored in the memory of the electronic device. For example, device 100-1 detects a tap gesture including a contact on an icon for a tic-tac-toe application not stored on the device. In some embodiments, the input is a tap gesture on a download icon, which initiates automatic downloading and installation of the first interactive application on the device (e.g., as soon as the device detects the tap gesture, the application begins downloading on the device). In some embodiments, the input is a tap gesture on a download confirmation icon, which asks the user to confirm that the user wants to download the first interactive application and which initiates automatic downloading and installation of the first interactive application on the device (e.g., in response to detecting the tap gesture, the device displays a request to confirm the download request and/or confirm the identity of the user.

0997In response to detecting the input that corresponds to the request to download the first interactive application, the device (4630) downloads the first interactive application to the memory of the electronic device, replaces display of the application store user interface with display of the messaging user interface (e.g., messaging user interface 3500 in <figref idref="f0472">Figure 38AS</figref>), the messaging user interface including the conversation transcript (e.g., conversation transcript 3503 in <figref idref="f0472">Figure 38AS</figref>) and at least some of the plurality of launch icons for interactive applications (e.g., some of the launch icons displayed in application selection tray 3654 in <figref idref="f0472">Figure 38AS</figref>). In some embodiments, the messaging user interface also includes a messaging-input area (e.g., message-input area 3502 in <figref idref="f0472">Figure 38AS</figref>. The device also adds a launch icon that corresponds to the first interactive application to the display of the plurality of launch icons for interactive applications (e.g., the device would add application launch icon 3603 for the downloading tic-tac-toe application to application selection tray 3654 in <figref idref="f0472">Figure 38AS</figref>.

0998In some embodiments, adding a launch icon that corresponds to the first interactive application to the display of the plurality of launch icons for interactive applications includes displaying (4632) an indicia (e.g. an animation indicating) that the first interactive application is being downloaded. For example, an indicia similar to indicia 3709, indicating download of a tic-tac-toe application, in <figref idref="f0373">Figure 37BH</figref>.

0999In some embodiments, the indicia (e.g., the animation) indicates (4634) the progress of the download of the first interactive application. For example, in <figref idref="f0373">Figure 37BH</figref>, the size of the partial circle in indicia 3709 grows, in accordance with a percentage of the application that is downloaded, until the application is completely downloaded.

1000It should be understood that the particular order in which the operations in <figref idref="f0570 f0572">Figures 46A-46C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 4600 described above with respect to <figref idref="f0570 f0572">Figures 46A-46C</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 4600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1001In accordance with some embodiments, <figref idref="f0573">Figure 47</figref> shows a functional block diagram of an electronic device 4700 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention.

In some embodiments, the processing unit 4706 includes a detecting unit 4708, a display enabling unit 4710, a ceasing unit 4712, a downloading unit 4714, a display replacing unit 4716, and an adding unit 4718.

1003The processing unit 4706 is configured to: enable display of a messaging user interface of a messaging application on the display unit 4702, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and an application affordance (e.g., with the display enabling unit 4710); while displaying the messaging user interface, detect an input that activates the application affordance (e.g., with the detecting unit 4708); in response to detecting the input that activates the application affordance, concurrently enable display of a launch icon for an application store and a plurality of launch icons for interactive applications, wherein activation of a respective launch icon for an interactive application launches a corresponding application that is displayed within the messaging application (e.g., with the display enabling unit 4710); detect an input that activates the launch icon for the application store (e.g., with the detecting unit 4708); in response to detecting the input that activates the launch icon for the application store: cease to display the messaging user interface (e.g., with the ceasing unit 4712), and enable display of an application store user interface, including display of at least one interactive application available for download to the electronic device (e.g., with the display enabling unit 4710); while displaying the application store user interface, detect an input that corresponds to a request to download a first interactive application that is not stored in the memory of the electronic device (e.g., with the detecting unit 4708); and, in response to detecting the input that corresponds to the request to download the first interactive application: download the first interactive application to the memory of the electronic device (e.g., with the downloading unit 4714); replace display of the application store user interface with display of the messaging user interface, the messaging user interface including the conversation transcript and at least some of the plurality of launch icons for interactive applications (e.g., with the display replacing unit 4716); and add a launch icon that corresponds to the first interactive application to the display of the plurality of launch icons for interactive applications (e.g., with the adding unit 4718).

1004In some embodiments, adding a launch icon that corresponds to the first interactive application to the display of the plurality of launch icons for interactive applications includes displaying an indicia that the first interactive application is being downloaded.

1005In some embodiments, the indicia indicates the progress of the download of the first interactive application.

1006In some embodiments, the interactive application is configured to perform a subset of the functions of a corresponding application operated separate from the messaging application.

1007In some embodiments, the interactive application launch icon displays an identifier for a corresponding application operated separate from the messaging application.

1008In some embodiments, the interactive application displays a portion of the content displayed by a corresponding application operated separate from the messaging application.

1009In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input.

1011In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application.

1012In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application.

1013In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application.

1014The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1015The operations described above with reference to <figref idref="f0570 f0572">Figures 46A-46C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0573">Figure 47</figref>. For example, detection operations 4604 and 4624 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1016<figref idref="f0574 f0577">Figures 48A-48D</figref> are flow diagrams illustrating a method 4800 of posting messages to a messaging session from a user interface other than the user interface for the messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.

1017As described below, the method 4800 provides an intuitive way to post messages to a messaging session from a user interface other than the user interface for the messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when posting messages to a messaging session from a user interface other than the user interface for the messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to post messages to a messaging session from a user interface other than the user interface for the messaging application faster and more efficiently conserves power and increases the time between battery charges.

1018The device displays (4802) a messaging user interface of a messaging application on the display (e.g., messaging user interface 3500 in <figref idref="f0319">Figures 37F</figref>, <figref idref="f0328">37O</figref>, and <figref idref="f0358">37AS</figref>), the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display, such as conversation transcript 3700 in <figref idref="f0319">Figures 37F</figref>, <figref idref="f0328">37O</figref>, and <figref idref="f0358">37AS</figref>) of a messaging session between a user of the electronic device and at least one other user {e.g., of another electronic device}, a first message-input area (e.g., message-input area 3502 in <figref idref="f0319">Figures 37F</figref>, <figref idref="f0328">37O</figref>, and <figref idref="f0358">37AS</figref>), and a launch icon for an interactive application (e.g., an application operated within the messaging application than can be updated by all participants of the messaging session; e.g., launch icon 3708 for an interactive reservations application, reservations interactive application object 3728 displayed in transcript 3700 in <figref idref="f0328">Figure 37O</figref>, and launch icon 3774 for an interactive tic-tac-toe application in <figref idref="f0358">Figure 37AS</figref>).

1019In some embodiments, once the interactive application is posted to the messaging session, any participant of the session may open the interactive application, make a change within the interactive application (e.g., change a location on a map, select a topping for a pizza, make or change an appointment, or take a turn in a game, such as tic-tac-toe), and the change is sent to all participants of the messaging session. For example, once a session of a reservations interactive application is posted to a messaging session corresponding to conversation transcript 3700, as illustrated by display of reservation application object 3728 in transcript 3700 in <figref idref="f0328">Figure 37O</figref>, any user included in the messaging transcript can open the application session and change the time of the reservation. This is illustrated, for example, in <figref idref="f0329 f0342">Figures 37P-37AC</figref>, where Abe, the operator of device 100-2, changes the time of the reservation made by Andrew, the operator of device 100-1, from 6:30 PM, as shown in <figref idref="f0329">Figure 37P</figref>, to 8:00 PM, as shown in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> AC.

1020In some embodiments, the first message input area is configured to display text and other content ready to be posted to the messaging session. For example, after receiving input of message 3736 in <figref idref="f0327">Figure 37N</figref>, the message is posted to the messaging session, as illustrated by display of message 3736 in conversation transcript 3700 in <figref idref="f0328">Figure 37O</figref>.

1021In some embodiments, the launch icon for the interactive application is concurrently displayed (4804) with a plurality of launch icons for other interactive applications in the messaging user interface. For example, launch icon 3603 for an interactive tic-tac-toe application and launch icon 3605 for an interactive reservation application are displayed in application selection tray 3654 with other launch icons for interactive applications-e.g., application launch icon 3611 for a live video-streaming application, application launch icon 3613 for an interactive pizza ordering application, and application launch icon 3615 for an interactive music application.

1022In some embodiments, the interactive application launch icon displays (4806) an identifier for a corresponding application operated separate from the messaging application. For example, application launch icon 3708 for an interactive reservations application displays concentric circle identifiers for a corresponding reservation application operated outside of the messaging application.

1023While displaying the messaging user interface, the device detects (4808) an input that activates the launch icon for the interactive application. In some embodiments, the input is a tap gesture on the launch icon. For example, device 100-1 detects a tap gesture including contact 3710 on launch icon 3708 in <figref idref="f0319">Figure 37F</figref>, activating a corresponding interactive reservations application in <figref idref="f0320">Figure 37G</figref>. For example, device 100-2 detects a tap gesture including contact 3738 on reservations application object 3728 in <figref idref="f0329">Figure 37P</figref>, activating a corresponding interactive reservations application in <figref idref="f0330">Figure 37Q</figref>. For example, device 100-1 detects a tap gesture including contact 3776 on tic-tac-toe application launch icon 3774 in <figref idref="f0359">Figure 37AT</figref>, activating a corresponding interactive tic-tac-toe application in <figref idref="f0360">Figure 37AU</figref>.

1024In some embodiments, detecting the input that activates the launch icon for the interactive application includes (4810) detecting a first input by a first contact at a location corresponding to the launch icon for the interactive application, in response to detecting the first input, displaying a menu that includes a plurality of options for how to run the interactive application (e.g., to play tic-tac-toe as "X" or "O"; to operate the interactive application in full-screen mode or embedded within the messaging user interface), and detecting a second input that selects a first option in the plurality of options for how to run the interactive application.

1025For example, device 100-1 detects a tap gesture including contact 3776 on tic-tac-toe launch icon 3774 in <figref idref="f0359">Figure 37AT</figref>. In response to detecting the contact, the device displays menu 3778 including options 3780-1 and 3780-2 for playing the game as 'O' or 'X', respectively. Responsive to detecting selection of 'O' via a tap gesture on affordance 3780-1, including contact 3782 in <figref idref="f0361">Figure 37AV</figref>, device 100-1 displays tic-tac-toe user interface 3784 over a portion of messaging user interface 3500 in <figref idref="f0362">Figure 37AW</figref>.

1026In some embodiments, the second input is a continuation of the first input, such as, dragging a first contact to a location corresponding to the first option and lifting-off, or increasing the intensity of the first contact, to select the first option. In some embodiments, the second input is by a second contact at a location corresponding to the first option, e.g., a tap gesture on the first option. In some embodiments, the menu is displayed on top of the launch icon and/or the plurality of launch icons. In some embodiments, the menu replaces display of the interactive launch icon, which includes ceasing to display the launch icon or plurality of launch icons and displaying the menu where the launch icon(s) had been displayed. For example, menu 3778 in <figref idref="f0360">Figure 37AU</figref> replaces display of interactive launch icon 3774 in response to detecting contact 3776 in <figref idref="f0359">Figure 37AT</figref>.

1027In response to detecting the input that activates the launch icon for the interactive application, the device displays (4812) a user interface for the interactive application (e.g., an "interactive application user interface"). The interactive application user interface includes a second message-input area that is distinct from the first message-input area. For example, interactive reservation application user interface 3712 includes message-input area 3716 in <figref idref="f0320">Figures 37G</figref> and <figref idref="f0330">37Q</figref>, which is separate from message-input area 3502 displayed in the messaging user interface 3500 in <figref idref="f0319">Figures 37F</figref> and <figref idref="f0329">37P</figref>. Similarly, interactive tic-tac-toe application user interface 3784 includes message-input area 3716 in <figref idref="f0362">Figure 37AW</figref>, which is separate from message-input area 3502 displayed in the messaging user interface 3500, as seen in the background of <figref idref="f0362">Figure 37AW</figref>.

1028In some embodiments, the interactive application user interface is displayed over at least a portion of the messaging user interface. For example, interactive tic-tac-toe application user interface 3784 is displayed over a portion of messaging user interface 3500 in <figref idref="f0362">Figure 37AW</figref>. In some embodiments, where the interactive application user interface is displayed over a portion of the messaging user interface, the messaging user interface is blurred, faded, or otherwise obscured to emphasize display of the interactive application user interface.

1029In some embodiments, the interactive application user interface replaces display of the messaging user interface. For example, interactive reservations application user interface 3712, illustrated in <figref idref="f0320">Figure 37G</figref>, replaces display of messaging user interface 3500 in <figref idref="f0319">Figure 37F</figref>, upon activation.

1030In some embodiments, the interactive application user interface, or a portion of the interactive application user interface (e.g., where the interactive application user interface is displayed in more than one continuous area on the display) is displayed within the message transcript. For example, pizza application object 3735, displayed within transcript 3700 in <figref idref="f0392">Figure 37CA</figref>, is a non-contiguous portion of the user interface for an interactive pizza ordering application, because it displays a current status of the pizza being ordered. For example, in response to pepperoni being added to the pizza in <figref idref="f0395">Figure 37CD</figref>, pizza ordering application object 3735 displays pepperoni on the pizza in <figref idref="f0396">Figure 37CE</figref>.

1031In some embodiments, the user interface for the interactive application includes (4814) at least one avatar, each respective avatar in the at least one avatar corresponding to a user in the at least one other user included in the messaging session. For example, user interface 3712 for an interactive reservation application displays avatar 3510 corresponding to Abe, when displayed on device 100-1 (e.g., operated by Andrew) in <figref idref="f0320">Figure 37G</figref>, and displays avatar 3511 corresponding to Andrew, when displayed on device 100-2 (e.g., operated by Abe).

1032In some embodiments, the user interface for the interactive application includes (4816) a plurality of avatars displayed as a stack of avatars (e.g., an overlapping stack of avatars, such as stack of avatars 4002 in <figref idref="f0529">Figure 40A</figref>.

1033In some embodiments, while displaying the interactive application user interface, the device (4818) detects a third input by a third contact at a location corresponding to an avatar within the user interface for the interactive application and, in response to detecting the third input, displaying a menu of actions, that are associated with the avatar (e.g., for sending to the user associated with the avatar a personal message, calling, video chatting, sending a payment, and/or sending a digital touch). In some embodiments, the menu or actions is overlaid on top of the user interface for the interactive application. For example, responsive to detecting a input including an increase in a characteristic intensity of contact 3799 from <figref idref="f0352">Figure 37AM to 37AM</figref>, while over avatar 3510 in reservations application user interface 3712, menu 3882 of actions 3884 is displayed in <figref idref="f0353">Figure 37AN</figref>.

1034In some embodiments, the interactive application is configured (4820) to perform a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1035In some embodiments, the interactive application displays (4822) a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application displays restaurant ratings but not user comments on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application displays both restaurant ratings and user comments on a restaurant.

1036In some embodiments, the interactive application causes (4824) the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application launch icon 3708 in <figref idref="f0319">Figure 37F</figref>, the device launches the interactive reservations application within the messaging application. In response to a second (e.g., different) input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application launch icon 3708 in <figref idref="f0319">Figure 37F</figref>, the device launches a reservations application outside of the messaging application.

1037In some embodiments, the interactive application is operated (4826) separately from a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of launch icon 3708 in <figref idref="f0319">Figure 37F</figref> is operable when a corresponding reservations application operated outside of the messaging application is not running.

1038In some embodiments, the interactive application is operated (4828) in conjunction with a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of launch icon 3708 in <figref idref="f0319">Figure 37F</figref> is not operable when a corresponding reservations application operated outside of the messaging application is not running.

1039In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage (4830) that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of reservations made using the interactive reservations application operated within the messaging application are stored in a different portion of memory than records of reservations made using a corresponding reservations application operated outside of the messaging application.

1040In some embodiments, the corresponding application operated separate from the messaging application is configured (4832) to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding reservations application operated outside of the messaging application can access the records of reservations made using the interactive reservations application operated within the messaging application..

1041While displaying the interactive application user interface, the device detects (4834) an input of a first message in the second message-input area. For example, while displaying interactive reservations application user interface 3712, device 100-2 detects input of message 3746 in message-input area 3716 in <figref idref="f0332">Figure 37S</figref>.

1042In response to detecting the input of the first message in the second message-input area, the device displays (4836) the first message in the second message-input area. For example, in response to detecting input of message 3746, device 100-2 displays the message in message-input area 3716 in <figref idref="f0333">Figure 37T</figref>.

1043While displaying the first message in the second message-input area, the device detects (4838) an input that corresponds to a request to post the contents of the second message-input area to the messaging session. In some embodiments, the input is a tap gesture on a send icon. For example, device 100-2 detects an input including contact 3748 on sending affordance 3520 in <figref idref="f0334">Figure 37U</figref>.

1044In response to detecting the input that corresponds to the request to post the contents of the second message-input area to the messaging session, the device transmits (4840) the first message to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the first message in a conversation transcript corresponding to the messaging session. For example, in response to detecting the input including contact 3748 on sending affordance 3520 in <figref idref="f0334">Figure 37U</figref>, device 100-2 transmits message 3746 at 9:29 AM to other device 100-1 associated with Andrew, who is included in the messaging session. Device 100-1 receives message 3746 and displays it within conversation transcript 3700 at 9:29 AM, in <figref idref="f0344">Figure 37AE</figref>.

1045In some embodiments, after detecting the input that corresponds to the request to post the contents of the second message-input area to the messaging session, and while displaying the user interface for the interactive application, the device detects an input terminating the interactive application (e.g., a tap on the close button; for example, a tap gesture including contact 3756 on exit affordance 3714 in Figure 3756) and, in response to detecting the input terminating the interactive application, the device (4842) ceases to display the user interface for the interactive application and displays the messaging user interface, the messaging user interface including display of the first message in the conversation transcript. For example, responsive to a tap gesture including contact 3756 on exit affordance 3714 in Figure 3756, device 100-2 replaces display of interactive reservations application user interface 3712 in <figref idref="f0341">Figure 37AB</figref> with display of messaging user interface 3500 in <figref idref="f0342">Figure 37AC</figref>. Message 3746, posted while device 100-2 was displaying interactive reservations application user interface 3712 in <figref idref="f0334 f0335">Figures 37U-37V</figref>, is displayed in conversation transcript 3700 in <figref idref="f0342">Figure 37AC</figref>.

1046In some embodiments, while displaying the user interface for the interactive application (e.g., in full-screen mode), the device (4844) receives a message associated with the messaging session and, in response to receiving the message associated with the messaging session, transiently displays the message overlaid on top of the user interface for the interactive application. For example, while displaying user interface 3712 for an interactive reservations application in full screen mode in <figref idref="f0335">Figure 37V</figref>, associated with a messaging session corresponding to conversation transcript 3700 in <figref idref="f0329">Figure 37P</figref>, device 100-2 receives message 3750, associated with the messaging session corresponding to conversation transcript 3700 at 9:30 AM, and transiently displays the message over user interface 3712 in <figref idref="f0336">Figure 37W</figref>, even though conversation transcript 3700 is not displayed in user interface 3712.

1047In some embodiments, messages associated with other messaging sessions are not displayed over the interactive application user interface when received. For example, message 4114, posted at 9:28 AM, to a messaging session associated with conversation transcript 3503 in <figref idref="f0555">Figure 41D</figref> is not displayed over interactive user interface 3712 in <figref idref="f0330 f0333">Figures 37Q-37T</figref> (e.g., at 9:28 AM), even though device 100-2 corresponds to user "Abe," who is also included in the messaging session associated with conversation transcript 3503.

1048It should be understood that the particular order in which the operations in <figref idref="f0574 f0577">Figures 48A-48D</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 700 described above with respect to <figref idref="f0574 f0577">Figures 48A-48D</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 4800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1049In accordance with some embodiments, <figref idref="f0578">Figure 49</figref> shows a functional block diagram of an electronic device 4900 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0578">Figure 49</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

1050As shown in <figref idref="f0578">Figure 49</figref>, an electronic device 4900 includes a display unit 4902 configured to display user interfaces; a touch-sensitive surface unit 4904 configured to detect contacts; and a processing unit 4906 coupled with the display unit 4902 and the touch-sensitive surface unit 4904. In some embodiments, the processing unit 4906 includes a detecting unit 4908, a display enabling unit 4910, a ceasing unit 4912, a transmitting unit 4914, and a receiving unit 4916.

1051The processing unit 4906 is configured to: enable display of a messaging user interface of a messaging application on the display unit 4902 (e.g., with the display enabling unit 4910), the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, a first message-input area, and a launch icon for an interactive application; while displaying the messaging user interface, detect an input that activates the launch icon for the interactive application (e.g., with the detecting unit 4908); in response to detecting the input that activates the launch icon for the interactive application, enable display of a user interface for the interactive application (e.g., with the display enabling unit 4910), the interactive application user interface including a second message-input area that is distinct from the first message-input area; while displaying the interactive application user interface, detect input of a first message in the second message-input area (e.g., with the detecting unit 4908); in response to detecting the input of the first message in the second message-input area, enable display of the first message in the second message-input area (e.g., with the display enabling unit 4910); while displaying the first message in the second message-input area, detect an input that corresponds to a request to post the contents of the second message-input area to the messaging session (e.g., with the detecting unit 4908); and, in response to detecting the input that corresponds to the request to post the contents of the second message-input area to the messaging session, transmit the first message to one or more electronic devices that correspond to the at least one other user included in the messaging session (e.g., with the transmitting unit 4914), wherein the one or more electronic devices display the first message in a conversation transcript corresponding to the messaging session.

1052In some embodiments, the processing unit 4906 is further configured to: after detecting the input that corresponds to the request to post the contents of the second message-input area to the messaging session, and while displaying the user interface for the interactive application, detect an input terminating the interactive application (e.g., with the detecting unit 4908); and, in response to detecting the input terminating the interactive application: cease to display the user interface for the interactive application (e.g., with the ceasing unit 4912), and enable display of the messaging user interface (e.g., with the display enabling unit 4910), the messaging user interface including display of the first message in the conversation transcript.

1053In some embodiments, the launch icon for the interactive application is concurrently displayed with a plurality of launch icons for other interactive applications in the messaging user interface.

1054In some embodiments, detecting the input that activates the launch icon for the interactive application includes: detecting a first input by a first contact at a location corresponding to the launch icon for the interactive application; in response to detecting the first input, displaying a menu that includes a plurality of options for how to run the interactive application; and detecting a second input that selects a first option in the plurality of options for how to run the interactive application.

1055In some embodiments, the user interface for the interactive application includes at least one avatar, each respective avatar in the at least one avatar corresponding to a user in the at least one other user included in the messaging session.

1056In some embodiments, the user interface for the interactive application includes a plurality of avatars displayed as a stack of avatars.

1057In some embodiments, the processing unit 4906 is further configured to: while displaying the interactive application user interface: detect a third input by a third contact at a location corresponding to an avatar within the user interface for the interactive application (e.g., with the detecting unit 4908); and, in response to detecting the third input, enable display of a menu of actions, that are associated with the avatar (e.g., with the display enabling unit 4910).

1058In some embodiments, the processing unit 4906 is further configured to: while displaying the user interface for the interactive application: receive a message associated with the messaging session (e.g., with the receiving unit 4916); and, in response to receiving the message associated with the messaging session, transiently enable display of the message overlaid on top of the user interface for the interactive application (e.g., with the display enabling unit 4910).

1059In some embodiments, the interactive application is configured to perform a subset of the functions of a corresponding application operated separate from the messaging application.

1060In some embodiments, the interactive application launch icon displays an identifier for a corresponding application operated separate from the messaging application.

1061In some embodiments, the interactive application displays a portion of the content displayed by a corresponding application operated separate from the messaging application.

1062In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input.

1063In some embodiments, the interactive application is operated separately from a corresponding application operated separate from the messaging application.

1064In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application.

1065In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application.

1066In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application.

1067The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1068The operations described above with reference to <figref idref="f0574 f0577">Figures 48A-48D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0578">Figure 49</figref>. For example, detection operations 4808 and 4834 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1069<figref idref="f0579 f0581">Figures 50A-50C</figref> are flow diagrams illustrating a method 5000 of using an interactive application in a messaging application in accordance with some embodiments. The method 5000 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 5000 are, optionally, combined and/or the order of some operations is, optionally, changed.

1070As described below, the method 5000 provides an intuitive way to use an interactive application in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when using an interactive application in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to use an interactive application in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1071The device displays (5002) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a message-input area, and an icon for an interactive application ("interactive application icon" or "interactive application object") that is displayed within the conversation transcript.

1072As used herein, "interactive application icon" and "interactive application object" are used interchangeably to refer to an item, displayed in a conversation transcript of a messaging session, which is associated with an interactive application in a messaging application, and specifically with a session of the interactive application initiated within the messaging session. When activated in a messaging session, the interactive application object causes launch of a user interface for the associated interactive application, and specifically for the session of the interactive application initiated within the messaging session.

1073For example, messaging user interface 3500 in <figref idref="f0324">Figure 37K</figref> includes conversation transcript 3700, message-input area 3502, and icon (e.g., object) 3728 corresponding to an interactive reservations application. Icon 3728 includes identifier 3730, representing that the icon is associated with the interactive reservations application. Icon 3728 also includes information about content input into the associated session of the interactive application, for example, that a reservation was made for two people at 6:45 PM at Joe's Bistro, serving American Fare.

1074As another example, messaging user interface 3500 in <figref idref="f0374">Figure 37BI</figref> includes conversation transcript 3700, message-input area 3502, and icon (e.g., object) 3705 corresponding to an interactive tic-tac-toe application. Icon 3502 includes an identifying image of a tic-tac-toe board with an X and an O that were entered by users in the messaging session.

1075As another example, messaging user interface 3500 in <figref idref="f0411">Figure 37CT</figref> includes conversation transcript 3700, message-input area 3502, and icon (e.g., object) 3735 corresponding to an interactive pizza ordering application. Icon 3502 does not include identifying information about the interactive application, but does include information about inputs made in the associated session of the interactive application, namely that pepperoni was added to the pizza being designed.

1076In some embodiments, further information about the state of the associated application or session of the interactive application is displayed proximal to an interactive application icon/object. For example, in <figref idref="f0371">Figure 37BF</figref>, additional information 3795 is displayed below icon 3705, indicating that the corresponding interactive tic-tac-toe application is not stored in memory of device 100-2. In another example, in <figref idref="f0410">Figure 37CS</figref>, additional information 3797 is displayed below icon 3735, indicating that Abe added pepperoni to the pizza being designed in the session of the interactive pizza ordering application associated with icon 3735 (e.g., the last change made with in the session of the application).

1077In some embodiments, no further information about the state of the associated application or session of the interactive application is displayed proximal to an interactive application icon/object. For example, in <figref idref="f0324">Figure 37K</figref>, no additional information about the state of the associated application of session of the interactive application is displayed proximal to interactive application icon 3728.

1078In some embodiments, an interactive application launch icon displays (5004) an identifier for a corresponding application operated separate from the messaging application. In some embodiments interactive application icons/objects function as application launch icons by enabling launch of a user interface for the interactive application associated with the application icon/object. For example, upon activation of interactive application icon 3728, by an input including contact 3738 in <figref idref="f0329">Figure 37P</figref>, device 100-2 displays user interface 3712 for the corresponding interactive reservations application in <figref idref="f0330">Figure 37Q</figref>. The display of icon 3728 includes identifier 3730 for a corresponding reservations application operated separate from the messaging application.

1079While displaying the messaging user interface, the device detects (5006) an input that activates the icon for the interactive application. In some embodiments, the input is a tap gesture on the icon. For example, device 100-2 detects an input including contact 3738 on icon 3728 for an interactive reservations application, in <figref idref="f0329">Figure 37P</figref>. As another example, device 100-2 detects an input including contact 3711 on icon 3705 for an interactive tic-tac-toe application, in <figref idref="f0375">Figure 37BJ</figref>. As another example, device 100-1 detects an input including contact 3765 on icon 3735 for an interactive pizza ordering application, in <figref idref="f0417">Figure 37CZ</figref>.

1080In response to detecting the input that activates the icon for the interactive application, the device displays (5008) a user interface for the interactive application ("interactive application user interface") in a first state. For example, device 100-2 displays user interface 3712 for an interactive reservations application in a first state that includes display of a 6:45 PM reservation for 2 people at Joe's Bistro, in <figref idref="f0330">Figure 37Q</figref>. As another example, device 100-2 displays user interface 3782 for an interactive tic-tac-toe application in a first state that includes display of an 'O' in the center square of tic-tac-toe board 7391 and display of no 'X' on tic-tac-toe board 3791, in <figref idref="f0376">Figure 37BK</figref>. As another example, device 100-1 displays a non-contiguous user interface for an interactive pizza ordering application, including application input area 3731 and application object 3735 in a first state that includes display of pepperoni on the pizza displayed in application object 3735. In some embodiments, the output display of an interactive application (e.g., the pizza displayed in application object 3735 in <figref idref="f0418">Figure 37DA</figref>) is also included in an application input area (e.g., the pizza could be displayed in a corner of input area 3731 in <figref idref="f0418">Figure 37DA</figref>.

1081In some embodiments, the interactive application user interface is displayed over at least a portion of the messaging user interface. For example, user interface 3782 for an interactive tic-tac-toe application is displayed over a portion of messaging user interface 3500 in <figref idref="f0376">Figure 37BK</figref>.

1082In some embodiments, the interactive application user interface replaces display of the messaging user interface. For example, user interface 3712 for an interactive reservations application in <figref idref="f0330">Figure 37Q</figref> replaces display of messaging user interface in <figref idref="f0329">Figure 37P</figref>.

1083In some embodiments, the interactive application user interface is displayed within the message transcript. For example, pizza application object 3735, displayed within transcript 3700 in <figref idref="f0392">Figure 37CA</figref>, is a non-contiguous portion of the user interface for an interactive pizza ordering application, because it displays a current status of the pizza being ordered.

1084In some embodiments, the interactive application displays (5010) a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1085In some embodiments, the interactive application causes (5012) the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches the interactive reservations application within the messaging application. In response to a second, different input (e.g., a different one of a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches a reservations application outside of the messaging application.

1086In some embodiments, the interactive application is operated (5014) separately from a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is operable when a corresponding reservations application operated outside of the messaging application is not running.

1087In some embodiments, the interactive application is operated (5016) in conjunction with a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is not operable when a corresponding reservations application operated outside of the messaging application is not running.

1088In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage (5018) that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application are stored in a different portion of memory than records of reservations made using a corresponding reservations application operated outside of the messaging application.

1089In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding reservations application operated outside of the messaging application can access the records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application.

1090While displaying the user interface for the interactive application, the device detects (5022) a first user input within the user interface for the interactive application. For example, device 100-2 detects an input in interactive reservations user interface 3712 including contacts 3752 in <figref idref="f0337">Figure 37X</figref> and 3754 in <figref idref="f0339">Figure 37Z</figref>. As another example, device 100-2 detects an input in interactive tic-tac-toe application user interface 3782 including contact 3713 in <figref idref="f0377">Figure 37BL</figref>. As another example, device 100-1 detects an input in interactive pizza ordering application user interface 3731 (e.g., application input area 3731) including contacts 3767 in <figref idref="f0419">Figure 37DB</figref> and 3769 in <figref idref="f0421">Figure 37DD</figref>.

1091In response to detecting (or after detecting) the first user input within the user interface for the interactive application, the device (5023) changes display of the user interface for the interactive application from the first state to a second state (e.g., placing a second "O" on a tic-tac-toe board) and sends information (e.g., a meta-message, instructions, a representation of an indicia of the input), to the one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session, indicating that the first user input was made in the user interface for the interactive application, wherein the one or more electronic devices display an indicia of the first user input (e.g., indicate that the first user input was made).

1092For example, device 100-2 changes the time of the reservation from 6:45 PM to 8:00 PM in input affordance 3740-1 of interactive reservations application user interface 3712 in <figref idref="f0340">Figure 37AA</figref>. Device 100-2 also sends information, at 9:31 AM, to device 100-1 that the time of the reservation was changed. In response to receiving the information at 9:31 AM, device 100-1 indicates the change in the state of the session of the interactive reservations application by moving display of application icon (e.g., object) 3728 in conversation transcript 3700 from position 3728-a in <figref idref="f0350">Figure 37AK</figref> to position 3728-b in <figref idref="f0351">Figure 37AL</figref> and by changing the time of the reservation displayed within application icon 3728 from 6:45 PM in <figref idref="f0350">Figure 37AK</figref> to 8:00 PM in <figref idref="f0351">Figure 37AL</figref>.

1093In another example, device 100-2 places 'X' 3794 in the upper-right corner of tic-tac-toe board 3791 displayed in interactive tic-tac-toe application user interface 3782 in <figref idref="f0378">Figure 37BM</figref>. Device 100-2 also sends information, at 9:35 AM, to device 100-1 that the 'X' was placed on tic-tac-toe board 3791. In response to receiving the information at 9:35 AM, device 100-1 indicates the change in the state of the session of the interactive tic-tac-toe application by displaying 'X' 3794 in the upper-right corner of tic-tac-toe board 3791 in <figref idref="f0365">Figure 37AZ</figref>, by moving display of application icon (e.g., object) 3786 in conversation transcript 3700 from position 3786-a in <figref idref="f0364">Figure 37AY</figref> to position 3784-b in <figref idref="f0365">Figure 37AZ</figref>, and by displaying additional information 3795 "Your turn," in conversation transcript 3700, immediately below application icon 3786, in <figref idref="f0365">Figure 37AZ</figref>.

1094In another example, device 100-1 displays mushrooms on the pizza displayed in application object 3735 in <figref idref="f0422">Figure 37DE</figref>. Device 100-1 also sends information, at 9:42 AM, to device 100-2 that mushrooms were added to the pizza. In response to receiving the information at 9:42 AM, device 100-2 indicates the change in the state of the session of the interactive pizza ordering application by displaying mushrooms on application object (e.g. icon) 3735 in <figref idref="f0403">Figure 37CL</figref> and by changing additional information 3797 below application object 3735 from "you added pepperoni" in <figref idref="f0402">Figure 37CK</figref> to "Andrew added mushrooms" in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> CL.

1095In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes (5024) information that causes movement of a corresponding icon for the interactive application within (e.g., to the end of and/or to an opposite side of) a conversation transcript corresponding to the messaging session.

1096For example, an interactive application icon is placed at a particular place in a conversation transcript according to when it was first opened in (e.g., posted to) the messaging session. Thereafter, the interactive application icon is moved to the end of the transcript when a device corresponding to a user included in the messaging session changes the state of the session of the interactive application.

1097For example, information sent to device 100-1 causes the device to move display of application icon (e.g., object) 3728 in conversation transcript 3700 from position 3728-a in <figref idref="f0350">Figure 37AK</figref> to position 3728-b in <figref idref="f0351">Figure 37AL</figref>.

1098In another example, information sent to device 100-1 causes the device to move display of application icon (e.g., object) 3786 in conversation transcript 3700 from position 3786-a in <figref idref="f0364">Figure 37AY</figref> to position 3784-b in <figref idref="f0365">Figure 37AZ</figref>.

1099In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes (5026) information that causes movement of a corresponding icon for the interactive application from a first side of a conversation transcript corresponding to the messaging session to a second side of the conversation transcript

1100For example, an icon for an interactive application moves from the right side of the transcript to the left side of the transcript, to indicate that another user included in the messaging session (e.g., a device corresponding to another user) made a last input in the associated session of the interactive application (e.g., took a turn within the interactive application shared within the messaging session). In some embodiments, the information causes the one or more devices to move the icon only where the icon was already displayed on the first side (e.g., the side indicating that a post was made by the user of the electronic device, for example, the right side of conversation transcripts 3506 and 3700 displayed in messaging application user interface 3500) (e.g., a condition precedent must be met for a device in the one or more devices to move the application object). Otherwise, where the application object was already displayed on the second side of the conversation transcript when the information was received, the device maintains display of the application object on the second side upon receiving the information (e.g., instructions).

1101For example, information sent to device 100-1 causes the device to move display of application icon (e.g., object) 3728 in conversation transcript 3700 from position 3728-a, on the right side of conversation transcript 3700, in <figref idref="f0350">Figure 37AK</figref> to position 3728-b, on the left side of conversation transcript 3700, in <figref idref="f0351">Figure 37AL</figref>.

1102In another example, information sent to device 100-1 causes the device to move display of application icon (e.g., object) 3786 in conversation transcript 3700 from position 3786-a, on the right side of conversation transcript 3700, in <figref idref="f0364">Figure 37AY</figref> to position 3784-b, on the left side of conversation transcript 3700, in <figref idref="f0365">Figure 37AZ</figref>.

1103In some embodiments, when the application icon/object is moved from a first to a second temporal location within the conversation transcript (e.g., to represent that a new input was received within the session of the corresponding interactive application), an archiving icon/object is placed in the conversation transcript at the first temporal location, to memorialize the previous input that caused the application icon/object to be displayed at the first location.

1104For example, device 100-1 receives information, at 9:31 AM that the time of a reservation was changed by device 100-2. In response, the device moves interactive reservations application icon/object 3728 from position 3728-a, corresponding to a first temporal location in transcript 3700 in <figref idref="f0350">Figure 37AK</figref>, to position 3728-b, corresponding to a second temporal location in transcript 3700 in <figref idref="f0351">Figure 37AL</figref>. To memorialize that the reservation was first made at a time corresponding to the first temporal location position in transcript 3700 (e.g., position 3728-b), device 100-1 displays interactive reservations application archiving icon/object 3756, including information on the input made at the first time (e.g., that a reservation was made/suggested for 6:45 PM) and an symbol identifying the corresponding interactive application (e.g., the concentric circle symbol corresponding to the interactive reservations application). In some embodiments, the interactive application archiving icon/object includes only one of text describing the input and an application symbol. In some embodiments, the interactive application archiving icon/object includes both text describing the input and an application symbol

1105In some embodiments, when an interactive application archiving icon/object is activated, additional information on the input associated with that time is displayed. In some embodiments, the information is displayed by opening a user interface for the interactive application in a state corresponding to the state of the session of the interactive application at the time the input was made (e.g., showing a particular tic-tac-toe move made at that time). In some embodiments, the information is displayed within or over the conversation transcript (e.g., as an expansion of the interactive application archiving icon/object or as a pop-up area displayed over/within the messaging user interface (e.g., over at least a portion of the conversation transcript).

1106In some embodiments, where messages posted to the conversation by the user and other participants of the messaging session are displayed on opposite sides of the display, the icon is always displayed on the side corresponding to the user that made the last input (e.g., wherein display of the interactive application icon at the first side of the conversation transcript indicates that a user of the electronic device made a last input in the interactive application user interface, and display of the interactive application icon at the second side of the conversation transcript indicates that another user included in the messaging session made a last input in the interactive application user interface).

1107In some embodiments, where the interactive application is a turn-based application, the icon for the interactive application is always displayed on the side of the transcript corresponding to the user whose turn it is to make an input (e.g., wherein display of the interactive application icon at the first side of the conversation transcript indicates that it is another user included in the messaging session's turn to make an input, and display of the interactive application launch icon at the second side of the conversation transcript indicates that it is the user's turn to make an input.

1108In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes (5028) information that causes display of text, indicating the first user input was made, below (or above, next to, near, or proximate to), a corresponding icon for the interactive application within a conversation transcript corresponding to the messaging session.

1109For example, information sent to device 100-1 causes the device to display additional information 3795 "Your turn," in conversation transcript 3700, below (e.g., directly below) application icon 3786, in <figref idref="f0365">Figure 37AZ</figref>.

1110For example, information sent to device 100-2 causes the device to display additional information 3797 "Andrew added mushrooms" below (e.g., directly below) application object 3735 in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> CL.

1111In some embodiments, displaying text includes changing (e.g., updating) text displayed near the application object prior to receiving the information. For example, information sent to device 100-2 causes the device to update additional information 3797 displayed below (e.g., directly below) application object 3735 from "You added pepperoni" in <figref idref="f0402">Figure 37CK</figref> to "Andrew added mushrooms" in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> CL.

1112In some embodiments, the text indicates to the user that it is their turn to make a user input (e.g., "Your turn to play") or that it is another user's turn to make an input (e.g., "Abe's turn to play). In some embodiments, the text indicates the name of the user who made the user input (e.g., "Abe played an 'X'," or "Andrew changed the reservation").

1113In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes (5030) information that causes change of the appearance of a corresponding icon for the interactive application.

1114For example, information sent to device 100-2 causes the device to change the time of the reservation displayed within application icon 3728 from 6:45 PM in <figref idref="f0350">Figure 37AK</figref> to 8:00 PM in <figref idref="f0351">Figure 37AL</figref>.

1115In another example, information sent to device 100-1 causes the device to display mushrooms on application object (e.g. icon) 3735 in <figref idref="f0403">Figure 37CL</figref>.

1116In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes (5032) information that causes change of display of a corresponding user interface for the interactive application from a first state to a second state.

1117In some embodiments, where a corresponding interactive user interface is being displayed on another device when the first user makes an input (e.g., when the other device receives the information that the first user makes an input), the display of the other user is updated in real-time (e.g., an 'X' is placed on the tic-tac-toe board of the second user in real-time).

1118For example, interactive tic-tac-toe application user interface 3782 is displayed on touch screen 112 of device 100-1, in <figref idref="f0338">Figures 37Y</figref>, when the device receives information that 'X' 3794 was placed on corresponding tic-tac-board 3791 (e.g., displayed in corresponding tic-tac-toe application user interface 3782 associated with a messaging session corresponding to conversation transcript 3700) on device 100-2 at 9:35 AM. In response, device 100-1 displays 'X' 3794 on tic-tac-toe board 3782 in <figref idref="f0365">Figure 37AZ</figref> (e.g., because interactive tic-tac-toe application user interface 3782 was being displayed when the device received the information.

1119In some embodiments, when the corresponding interactive interface is not being displayed on the other device, the corresponding interactive user interface is updated upon opening on the device.

1120In some embodiments, the interactive application is configured (5034) to perform a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1121It should be understood that the particular order in which the operations in <figref idref="f0579 f0581">Figures 50A-50C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 700 described above with respect to <figref idref="f0579 f0581">Figures 50A-50C</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 5000 optionally have one or more of the characteristics of the [contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations] described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1122In accordance with some embodiments, <figref idref="f0582">Figure 51</figref> shows a functional block diagram of an electronic device 5100 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0582">Figure 51</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

1123As shown in <figref idref="f0582">Figure 51</figref>, an electronic device 5100 includes a display unit 5102 configured to display user interfaces; a touch-sensitive surface unit 5104 configured to detect contacts; and a processing unit 5106 coupled with the display unit 5102 and the touch-sensitive surface unit 5104. In some embodiments, the processing unit 5106 includes a detecting unit 5108, a display enabling unit 5110, a display changing unit 5112, and a sending unit 5114.

1124The processing unit 5106 is configured to: enable display of a messaging user interface of a messaging application on the display unit 5102 (e.g., with the display enabling unit 5110), the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, a message-input area, and an icon for an interactive application that is displayed within the conversation transcript; while displaying the messaging user interface, detect an input that activates the icon for the interactive application (e.g., with the detecting unit 5108); in response to detecting the input that activates the icon for the interactive application, enable display of a user interface for the interactive application in a first state (e.g., with the display enabling unit 5110); while displaying the user interface for the interactive application, detect a first user input within the user interface for the interactive application (e.g., with the detecting unit 5108); and, in response to detecting the first user input within the user interface for the interactive application: change display of the user interface for the interactive application from the first state to a second state (e.g., with the display changing unit 5112), and send information, to the one or more electronic devices that correspond to the at least one other user included in the messaging session, indicating that the first user input was made in the user interface for the interactive application (e.g., with the sending unit 5114), wherein the one or more electronic devices display an indicia of the first user input.

1125In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes information that causes movement of a corresponding icon for the interactive application within a conversation transcript corresponding to the messaging session.

1126In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes information that causes movement of a corresponding icon for the interactive application from a first side of a conversation transcript corresponding to the messaging session to a second side of the conversation transcript.

1127In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes information that causes display of text, indicating the first user input was made, below a corresponding icon for the interactive application within a conversation transcript corresponding to the messaging session.

1128In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes information that causes change of the appearance of a corresponding icon for the interactive application.

1129In some embodiments, the information indicating that the first user input was made in the user interface for the interactive application includes information that causes change of display of a corresponding user interface for the interactive application from a first state to a second state.

1130In some embodiments, the interactive application is configured to perform a subset of the functions of a corresponding application operated separate from the messaging application.

1131In some embodiments, the interactive application launch icon displays an identifier for a corresponding application operated separate from the messaging application.

1132In some embodiments, the interactive application displays a portion of the content displayed by a corresponding application operated separate from the messaging application.

1133In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input.

1134In some embodiments, the interactive application is operated separately from a corresponding application operated separate from the messaging application.

1135In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application.

1136In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application.

1137In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application.

1138The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1139The operations described above with reference to <figref idref="f0579 f0581">Figures 50A-50C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0582">Figure 51</figref>. For example, detection operations 5006 and 5022 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1140<figref idref="f0583 f0585">Figures 52A-52C</figref> are flow diagrams illustrating a method 5200 of using an interactive application in a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 5200 are, optionally, combined and/or the order of some operations is, optionally, changed.

1141As described below, the method 5200 provides an intuitive way to use an interactive application in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when using an interactive application in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to use an interactive application in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1142The device displays (5202) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), and a message-input area. For example, device 100-2 (operated by Abe) displays messaging user interface 3500 in <figref idref="f0323">Figures 37J</figref> and <figref idref="f0369">37BD</figref>, including conversation transcript 3700 and message-input area 3502.

1143While displaying the messaging user interface, the device receives (5204) instructions, from an (second) electronic device that corresponds to another user included in the messaging session (e.g., device 100-1 operated by Andrew in Figures and 37F and 37AV), to display an icon for an interactive application ("interactive application icon" or "interactive application object") in the conversation transcript.

1144In some embodiments, while displaying the messaging user interface, the device receives information (e.g., a meta-message, instructions, or a representation of an interactive application icon/object) from an (second) electronic device that corresponds to another user included in the messaging session (e.g., device 100-1 operated by Andrew in Figures and 37F and 37AV), that a session of an interactive application was initiated within the messaging session. In some embodiments, the information causes the electronic device to display an icon for the for the session of the interactive application in the conversation transcript.

1145For example, upon initiation of a session of an interactive reservations application, caused by detection of an input (e.g., a tap gesture) including contact 3710 on launch icon 3708 in <figref idref="f0319">Figure 37F</figref>, device 100-1 sends information to device 100-2 that a session of the interactive reservations application was initiated. Device 100-2 receives the information in <figref idref="f0323">Figure 37J</figref>. As another example, upon initiation of a session of an interactive tic-tac-toe application, device 100-2 receives information from device 100-1 in <figref idref="f0370">Figure 37BE</figref> that a session (e.g., game) of the interactive tic-tac-toe application was initiated.

1146In response to receiving the instructions, the device displays (5208) the icon (e.g., interactive application object) for the interactive application in the conversation transcript.

1147In some embodiments, in response to receiving the information that a session of an interactive application was initiated within the messaging session, the device displays an icon for the interactive application, that is associated with the session of the interactive application initiated within the messaging session, in the conversation transcript.

1148For example, in response to receiving information from device 100-2 in <figref idref="f0323">Figure 37J</figref>, device 100-1 displays interactive reservations application icon/object 3730 in conversation transcript 3700, in <figref idref="f0324">Figure 37K</figref>. As another example, in response to receiving information from device 10012 in <figref idref="f0370">Figure 37BE</figref>, device 100-1 displays interactive tic-tac-toe application icon/object 3705 in conversation transcript 3700, in <figref idref="f0371">Figure 37BF</figref>.

1149In some embodiments, the interactive application launch icon displays (5026) an identifier for a corresponding application operated separate from the messaging application. In some embodiments interactive application icons/objects function as application launch icons by enabling launch of a user interface for the interactive application associated with the application icon/object.

1150In some embodiments, the interactive application icon/object displays an identifier for a corresponding application operated separate from the messaging application. For example, in <figref idref="f0324">Figure 37K</figref>, interactive reservations application icon/object 3730 displays a concentric circle symbol that corresponds to a reservations application operated separate from the messaging application.

1151While displaying the icon for the interactive application in the conversation transcript, the device detects (5212) an input (e.g., a tap gesture) that activates the icon (e.g., launches the application) for the interactive application. For example, device 100-2 detects an input including contact 3738 on interactive application icon/object 3728, in <figref idref="f0329">Figure 37P</figref>, that activates an interactive reservations application. In another example, device 100-2 detects an input including contact 3707 on interactive application icon/object 3705, in <figref idref="f0372">Figure 37BG</figref>, that activates an interactive tic-tac-toe application.

1152In response to detecting (5212) the input that activates the icon for the interactive application displayed in the conversation transcript, in accordance with a determination that an interactive application that corresponds to the icon for the interactive application is stored in the memory of the electronic device, the device displays (5214) a user interface for the interactive application ("interactive application user interface").

1153For example, device 100-2 displays interactive reservations application user interface 3712, in <figref idref="f0330">Figure 37Q</figref>, because the interactive reservations application was stored in the device when the activating input, including contact 3738 in <figref idref="f0329">Figure 37P</figref>, was detected.

1154In some embodiments, the interactive application user interface is displayed over at least a portion of the messaging user interface. For example, user interface 3782 for an interactive tic-tac-toe application is displayed over a portion of messaging user interface 3500 in <figref idref="f0376">Figure 37BK</figref>.

1155In some embodiments, the interactive application user interface replaces display of the messaging user interface. For example, user interface 3712 for an interactive reservations application in <figref idref="f0330">Figure 37Q</figref> replaces display of messaging user interface in <figref idref="f0329">Figure 37P</figref>.

1156In some embodiments, the interactive application user interface is displayed within the message transcript. For example, pizza application object 3735, displayed within transcript 3700 in <figref idref="f0392">Figure 37CA</figref>, is a non-contiguous portion of the user interface for an interactive pizza ordering application, because it displays a current status of the pizza being ordered.

1157In response to detecting (5212) the input that activates the icon for the interactive application displayed in the conversation transcript, in accordance with a determination that the interactive application that corresponds to the icon for the interactive application is not stored in the memory of the electronic device, the device downloads the interactive application, from a remote server (e.g., a server that is part of an online application store that contains interactive applications for the messaging application), to the memory of the electronic device and, after downloading the interactive application from the remote server, displays the user interface for the interactive application.

1158For example, device 100-2 downloads an interactive tic-tac-toe application corresponding to interactive tic-tac-toe application icon/object 3705, as indicated by download status indicia 3709 in <figref idref="f0373">Figure 37BH</figref>, because the application was not stored in memory of the device when the activating input, including contact 3707 in <figref idref="f0372">Figure 37BG</figref>, was detected.

1159In some embodiments, downloading the interactive application includes a permissive step where a user input indicates approval of the download of the interactive application (e.g., an object is displayed prompting the user to confirm download of the application and/or confirm their identity). In some embodiments, the downloading occurs in the background, without requiring user authorization.

1160In some embodiments, the downloading occurs without navigating away from the messaging user interface. In some embodiments, the downloading occurs while maintaining display of the messaging user interface.

1161In some embodiments, the interactive application user interface is displayed over at least a portion of the messaging user interface. For example, user interface 3782 for an interactive tic-tac-toe application is displayed over a portion of messaging user interface 3500 in <figref idref="f0376">Figure 37BK</figref>.

1162In some embodiments, the interactive application user interface replaces display of the messaging user interface. For example, user interface 3712 for an interactive reservations application in <figref idref="f0330">Figure 37Q</figref> replaces display of messaging user interface in <figref idref="f0329">Figure 37P</figref>.

1163In some embodiments, the interactive application user interface is displayed within the message transcript. For example, pizza application object 3735, displayed within transcript 3700 in <figref idref="f0392">Figure 37CA</figref>, is a non-contiguous portion of the user interface for an interactive pizza ordering application, because it displays a current status of the pizza being ordered.

1164In some embodiments (5232), in accordance with a determination that the interactive application is not stored in the memory of the electronic device, the icon for the interactive application has a first appearance and, in accordance with a determination that the interactive application is stored in the memory of the electronic device, the icon for the interactive application has a second appearance that is different from the first appearance.

1165In some embodiments, in accordance with a determination that the interactive application is not stored in the memory of the electronic device, the device displays additional information near (e.g., below, above, next to, or proximate to) the icon for the interactive application, that indicates that the interactive application is not stored in the memory of the device. For example, device 100-2 displays additional information "Tap to download" below icon 3705 in <figref idref="f0371">Figure 37BF</figref> because the corresponding interactive tic-tac-toe application is not stored in memory of the device. In contrast, device 100-2 displays additional information "Your turn" below icon 3705 in <figref idref="f0374">Figure 37BI</figref>, after the corresponding interactive tic-tac-toe application was downloaded into memory of the device.

1166In some embodiments, the interactive application is configured (5216) to perform a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1167In some embodiments, the interactive application displays (5218) a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1168In some embodiments, the interactive application causes (5220) the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches the interactive reservations application within the messaging application. In response to a second (e.g., different) input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches a reservations application outside of the messaging application.

1169In some embodiments, the interactive application is operated (5222) separately from a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is operable when a corresponding reservations application operated outside of the messaging application is not running.

1170In some embodiments, the interactive application is operated (5224) in conjunction with a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is not operable when a corresponding reservations application operated outside of the messaging application is not running.

1171In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage (5226) that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application are stored in a different portion of memory than records of reservations made using a corresponding reservations application operated outside of the messaging application.

1172In some embodiments, the corresponding application operated separate from the messaging application is configured (5228) to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding reservations application operated outside of the messaging application can access the records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application.

1173In some embodiments (5232), the device detects termination of the interactive application and, in response to detecting termination of the interactive application, ceases to display the user interface for the interactive application and displays (e.g., restoring partial or complete display) the messaging user interface including the conversation transcript, wherein the icon for the interactive application is displayed at a position within the conversation transcript.

1174For example, device 100-2 displays messaging user interface 3500, including interactive reservations application icon/object 3728 within transcript 3700 in <figref idref="f0342">Figure 37AC</figref>, in response to detecting a termination input, including contact 3756 on termination (exiting) affordance 3714, in <figref idref="f0341">Figure 37AB</figref>.

1175In another example, device 100-2 restores, in <figref idref="f0380">Figure 37BO</figref>, the partial display of messaging user interface 3500 that was obscured by display of interactive tic-tac-toe application user interface 3782 in <figref idref="f0379">Figure 37BN</figref>, including interactive tic-tac-toe application icon/object 3705 within transcript 3700 in <figref idref="f0380">Figure 37BO</figref>, in response to detecting a termination input, including contact 3717 on termination (exiting) affordance 3794, in <figref idref="f0379">Figure 37BN</figref>.

1176In some embodiments, the position of the icon within the conversation transcript is dependent upon the temporal order in which the instructions to display the icon was received (e.g., when another user requested a session of the interactive application). In some embodiments, the position of the icon within the conversation transcript is dependent upon the temporal order in which the user terminated the interactive application (e.g., closing the application pushes the icon down in the transcript). In some embodiments, the position of the icon is dependent upon the temporal order in which the last input (e.g., by any user) was made within the interactive application.

1177It should be understood that the particular order in which the operations in <figref idref="f0583 f0585">Figures 52A-52C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 700 described above with respect to <figref idref="f0583 f0585">Figures 52A-52C</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described above with reference to method 5200 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5400, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1178In accordance with some embodiments, <figref idref="f0586">Figure 53</figref> shows a functional block diagram of an electronic device 5300 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0586">Figure 53</figref> may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

1179As shown in <figref idref="f0586">Figure 53</figref>, an electronic device 5300 includes a display unit 5302 configured to display user interfaces; a touch-sensitive surface unit 5304 configured to detect contacts; and a processing unit 5306 coupled with the display unit 5302 and the touch-sensitive surface unit 5304. In some embodiments, the processing unit 5306 includes a detecting unit 5308, a display enabling unit 5310, a ceasing unit 5312, a downloading unit 5314, and a receiving unit 5316.

1180The processing unit 5306 is configured to: enable display of a messaging user interface of a messaging application on the display unit 5302 (e.g., with the display enabling unit 5310), the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and a message-input area; while displaying the messaging user interface, receiving information, from an electronic device that corresponds to another user included in the messaging session, that causes display of an icon for an interactive application in the conversation transcript (e.g., with the receiving unit 5316); in response to receiving the information, enable display of the icon for the interactive application in the conversation transcript (e.g., with the display enabling unit 5310); while displaying the icon for the interactive application in the conversation transcript, detect an input that activates the icon for the interactive application (e.g., with the detecting unit 5308); and, in response to detecting the input that activates the icon for the interactive application displayed in the conversation transcript: in accordance with a determination that an interactive application that corresponds to the icon for the interactive application is stored in the memory of the electronic device, enable display of a user interface for the interactive application (e.g., with the display enabling unit 5310), and in accordance with a determination that the interactive application that corresponds to the icon for the interactive application is not stored in the memory of the electronic device: download the interactive application, from a remote server, to the memory of the electronic device (e.g., with the downloading unit 5314), and after downloading the interactive application from the remote server, enable display of the user interface for the interactive application (e.g., with the display enabling unit 5310).

1181In some embodiments, the processing unit 5306 is further configured to: detect termination of the interactive application (e.g., with the detecting unit 5308), and, in response to detecting termination of the interactive application: cease to display the user interface for the interactive application (e.g., with the ceasing unit 5312); and enable display of the messaging user interface including the conversation transcript (e.g., with the display enabling unit 5310), wherein the icon for the interactive application is displayed at a position within the conversation transcript.

1182In some embodiments, in accordance with a determination that the interactive application is not stored in the memory of the electronic device, the icon for the interactive application has a first appearance; and in accordance with a determination that the interactive application is stored in the memory of the electronic device, the icon for the interactive application has a second appearance that is different from the first appearance.

1183In some embodiments, the interactive application is configured to perform a subset of the functions of a corresponding application operated separate from the messaging application.

1184In some embodiments, the interactive application launch icon displays an identifier for a corresponding application operated separate from the messaging application.

1185In some embodiments, the interactive application displays a portion of the content displayed by a corresponding application operated separate from the messaging application.

1186In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input.

1187In some embodiments, the interactive application is operated separately from a corresponding application operated separate from the messaging application.

1188In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application.

1189In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application.

1190In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application.

1191The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1192The operations described above with reference to <figref idref="f0583 f0585">Figures 52A-52C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0586">Figure 53</figref>. For example, detection operations 5210 and 5234 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1193<figref idref="f0587 f0589">Figures 54A-54C</figref> are flow diagrams illustrating a method 5400 of using an interactive application in a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 are, optionally, combined and/or the order of some operations is, optionally, changed.

1194As described below, the method 5400 provides an intuitive way to use an interactive application in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when using an interactive application in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to use an interactive application in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1195The device displays (5402) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript, displayed in a first area of the display, of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a first interactive application object displayed within the conversation transcript a message input area, and an input area for the first interactive application, distinct from the message input area, displayed in a second area of the display, the input area for the first interactive application including one or more input affordances.

1196For example, in <figref idref="f0392">Figures 37CA</figref> and <figref idref="f0418">37DA</figref>, devices 100-2 and 100-1, respectively, display messaging user interface 3500, including conversation transcript 3700 displayed in a top portion of touch screen 112, interactive pizza ordering application object 3735 within conversation transcript 3700, and interactive pizza ordering application input area 3731 displayed in a bottom portion of touch screen 112. Interactive pizza ordering input area 3731 includes input affordances 3733-1, 3733-2, and 3733-3 for adding toppings to a pizza being designed (e.g., for ordering), removing toppings from the pizza, and ordering the pizza, respectively.

1197In some embodiments, the interactive application object displays an output of the interactive application (e.g., an output of the interactive application is displayed on the interactive application object) in response to a user input. For example, in response to an input adding pepperoni to a pizza, including contacts 3737 and 3739 in <figref idref="f0393">Figures 37CB</figref> and <figref idref="f0395">37CD</figref>, pepperoni is displayed on interactive pizza ordering application object 3737 in <figref idref="f0396">Figure 37CE</figref>.

1198In some embodiments, the input area for the interactive application is displayed in a second area of the display while the conversation transcript is displayed in the first area of the display.

1199In some embodiments, display of the input area for the first interactive application replaces display of the conversation transcript, the first interactive application object, and/or the message input area (e.g., in response to detecting an input that activates the first interactive application object).

1200In some embodiments, the device (5404) displays content posted to the messaging session within the conversation transcript according to a temporal order in which the content was posted and the interactive application object is displayed at a position within the conversation transcript associated with the temporal order in which a session of the interactive application was initiated. For example, the interactive application object is positioned relative to other objects in the conversation transcript (e.g., messages, multimedia, and other content) according to a temporal order when a user first posted a session of the interactive application to the messaging session.

1201For example, in <figref idref="f0396 f0397">Figures 37CE-37CF</figref>, interactive tic-tac-toe application object 3735 is positioned between messages 3798 and 3741 in conversation transcript because message 3798 was posted to the messaging session first (e.g., at 9:36 in <figref idref="f0384">Figure 37BS</figref>), application object 3735 was posted second (e.g., at 9:37 PM in <figref idref="f0392">Figure 37CA</figref>), and message 3741 was posted last (e.g., at 9:39 AM in <figref idref="f0413">Figure 37CV</figref>).

1202In some embodiments, the device (5406) displays synchronous movement of content displayed in a temporal order within the conversation transcript (e.g., as new content is posted to the messaging session) towards an edge of the conversation transcript (e.g., the top of the conversation transcript), the displayed content including the first interactive application object and in accordance with a determination that the first interactive application object is within a predetermined distance from the edge of the conversation transcript, the device displays the first interactive application object at a fixed location on the display (e.g., at a top portion of the conversation transcript).

1203For example, in <figref idref="f0396">Figure 37CE</figref>, message 3798 and interactive tic-tac-toe application object 3735 are displayed according to the temporal order in which they were posted to the messaging session, as described above. In response to message 3741 being posted to the messaging session, device 100-2 moves message 3798 up and off of the top of touch screen 112 and interactive tic-tac-toe application object 3735 up to the top of conversation transcript 3700, from position 3735-a, in <figref idref="f0396">Figure 37CE</figref>, to position 3735, in <figref idref="f0397">Figure 37CF</figref>. Because interactive tic-tac-toe application object 3735 is displayed at a predefined position near the top of the displayed portion of the conversation transcript (e.g., at position 3735-b) it does not continue to move up when message 3747 is posted to the messaging session in <figref idref="f0401">Figure 37CJ</figref> (e.g., is remains displayed at position 3735-b).

1204In some embodiments, while displaying the first interactive application object at the fixed location on the display, the device continues (5408) to display synchronous movement of other content displayed in a temporal order within the conversation transcript.

1205For example, in <figref idref="f0400 f0402">Figures 37CI-37CK</figref>, although interactive tic-tac-toe application object 3735 has a fixed display at position 3735-b, message 3741 continues to scroll up on touch screen 112 as message 2747, In <figref idref="f0401">Figure 37CJ</figref>, and message 3749, in <figref idref="f0402">Figure 37CK</figref>, are posted to the messaging session.

1206In some embodiments, continuing to display synchronous movement of other content displayed in a temporal order with the conversation transcript includes that the device animates (5410) other content such that the other content appears to move behind the first interactive application object (e.g., the first interactive application UI appears to hover over the conversation transcript, which continues to scroll upwards as new content is posted to the messaging session).

1207For example, in <figref idref="f0400 f0402">Figures 37CI-37CK</figref>, while interactive tic-tac-toe application object 3735 is fixed at position 3735-b, message 3741 is animated to slide behind interactive tic-tac-toe application object 3735 as message 2747, In <figref idref="f0401">Figure 37CJ</figref>, and message 3749, in <figref idref="f0402">Figure 37CK</figref>, are posted to the messaging session.

1208In some embodiments, while displaying the first interactive application object at the fixed location on the display, the device (5418) detects a request to close the first interactive application (e.g., an input unpinning the interactive application object from the fixed position on the display) and, in response to detecting the request to close the first interactive application (or to unpin the interactive application object from the fixed position on the display), ceases to display the first interactive application object at the fixed location on the display and displays the first interactive application object at a position within the conversation transcript associated with the temporal order in which the session of the interactive application was initiated (e.g., the first interactive application UI is unpinned from the top of the conversation transcript and moves back to its original position within the transcript).

1209In some embodiments, the input unpinning the interactive application object from the fixed position on the display does not terminate display of an interactive application user interface (e.g., interactive pizza ordering application object 3735 may be unpinned from the fixed location on touch screen 112 without terminating display of interactive pizza ordering application input 3731.

1210In some embodiments, the input unpinning the interactive application object from the fixed position on the display (e.g., the displayed portion of the conversation transcript) is a user input (e.g., detected on a touch-sensitive surface, such as touch screen 112). For example, application object 3735 moves from fixed position 3735-b in conversation transcript 3700, in <figref idref="f0426">Figure 37DI</figref>, to original position 3735-a (e.g., its original temporal position in the messaging session), in <figref idref="f0427">Figure 37DJ</figref>, in response to an input ordering the pizza (e.g., and closing the interactive pizza ordering application), including contact 3775 on ordering affordance 3773-3, in <figref idref="f0426">Figure 37DI</figref>.

1211In some embodiments, the input unpinning the interactive application object from the fixed position on the display (e.g., the displayed portion of the conversation transcript) is an input (e.g., a meta-message, instruction, or information) from another electronic device that corresponds to another user included in the messaging session. For example, application object 3735 moves from fixed position 3735-b in conversation transcript 3700, in <figref idref="f0405">Figure 37CN</figref>, to original position 3735-a (e.g., its original temporal position in the messaging session), in <figref idref="f0406">Figure 37CO</figref> (as evidenced in <figref idref="f0408">Figure 37CQ</figref>), on touch screen 112 of device 100-2 in response to receiving information from device 100-1 that the pizza was ordered.

1212In some embodiments, the input unpinning the interactive application object from the fixed position on the display (e.g., the displayed portion of the conversation transcript) is an automatically generated input (e.g., a command) generated in response to a condition precedent (e.g., a timing-out of the first interactive application).

1213In some embodiments, the interactive application object is a display and/or user interface for the interactive application.

1214In some embodiments, the interactive application object is a launch icon for a session of the interactive application initiated within the messaging session.

1215While displaying the messaging user interface including the input area for the first interactive application, including one or more input affordances, the device detects (5420) an input that activates a first input affordance in the input area for the interactive application. For example, device 100-2 detects an input to add pepperoni to the pizza being designed, including contact 3737, in <figref idref="f0393">Figure 37CB</figref>, and contact 3739, in <figref idref="f0395">Figure 37CD</figref>.

1216In some embodiments, after detecting the input that activates the first input affordance, the device (5422) updates the first interactive application object that corresponds to the first interactive application in accordance with the input that activates the first input affordance (e.g., adds a topping on the pizza) and sends information (e.g., a meta-message, instructions, or a representation of the updated interactive application object) to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session, relating to the activation of the first input affordance (e.g., instructions to update a corresponding interactive application object that corresponds to the first interactive application displayed within a corresponding conversation transcript of the messaging session and/or information that pepperoni was added to the pizza).

1217For example, device 100-2 updates display of interactive pizza ordering application object 3735 by adding pepperoni on the pizza, in <figref idref="f0396">Figure 37CE</figref>, and sends information to device 100-1 that pepperoni was added to the pizza at 9:38 AM. Device 100-1 then updates display of interactive pizza ordering application object 3735 by adding pepperoni on the pizza, in <figref idref="f0410">Figure 37CS</figref>.

1218In some embodiments, prior to displaying the first interactive application object within the conversation transcript, the device (5426) displays the messaging user interface including the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between the user of the electronic device and the at least one other user (e.g., of another electronic device) and an application affordance. For example, device 100-1 displays messaging user interface 3500 including conversation transcript 3700 and application affordance 3508 in <figref idref="f0353">Figure 37AN</figref>.

1219While displaying the messaging user interface, the device detects an input that activates the application affordance (e.g., detecting a tap gesture at a location that corresponds to the application affordance). For example an input including contact 3768 on application affordance 3508 in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> AO.

1220In response to detecting the input that activates the application affordance, the device maintains display of at least a portion of the conversation transcript in a first area of the display and displays a second interactive application icon (e.g., a launch icon for a second interactive application), which is one of a plurality of interactive application icons, in a second area of the display (e.g., in a scrollable interactive application panel). For example, device 100-1 displays interactive reservations application launch icon 3708 in application slide tray 3892 in <figref idref="f0355">Figure 37AP</figref>.

1221In some embodiments, where the messaging user interface includes display of an electronic keyboard prior to activating the application affordance, the display of the scrollable interactive application panel replaces display of the keyboard. For example, display of application slide tray 3892, in <figref idref="f0388">Figure 37BW</figref>, replaces display of digital keyboard 3501, in <figref idref="f0387">Figure 37BV</figref>.

1222In some embodiments, where the messaging user interface includes a full-screen display of the conversation transcript prior to activating the application affordance, the display of the scrollable interactive application panel replaces a portion of the display of the message transcript. For example, conversation transcript 3700, displayed in full-screen mode in <figref idref="f0354">Figure 37AO</figref>, shrinks to accommodate display of application slide tray 3892 in <figref idref="f0355">Figure 37AP</figref>.

1223While displaying the second interactive application icon in the second area of the display, the device detects a first swipe gesture that includes horizontal movement of a first contact at a location that corresponds to the second area of the display. For example, device 100-1 detects a swipe gesture including movement 3772 of contact 3770 from position 3770 in Figure to position 3770-b in <figref idref="f0357">Figure 37AR</figref>.

1224In accordance with a determination that the first swipe gesture satisfies one or more interactive application icon switching criteria, the device replaces display of the second interactive application icon with display of a first interactive application icon that corresponds to the first interactive application in the second area of the display. For example, device 100-1 replaces interactive reservations application launch icon 3708 in slide tray 3892, in <figref idref="f0356">Figure 37AQ</figref>, with interactive tic-tac-toe application launch icon 3774 in slide tray 3892, in <figref idref="f0314 f0315 f0316 f0317 f0318 f0319 f0320 f0321 f0322 f0323 f0324 f0325 f0326 f0327 f0328 f0329 f0330 f0331 f0332 f0333 f0334 f0335 f0336 f0337 f0338 f0339 f0340 f0341 f0342 f0343 f0344 f0345 f0346 f0347 f0348 f0349 f0350 f0351 f0352 f0353 f0354 f0355 f0356 f0357 f0358 f0359 f0360 f0361 f0362 f0363 f0364 f0365 f0366 f0367 f0368 f0369 f0370 f0371 f0372 f0373 f0374 f0375 f0376 f0377 f0378 f0379 f0380 f0381 f0382 f0383 f0384 f0385 f0386 f0387 f0388 f0389 f0390 f0391 f0392 f0393 f0394 f0395 f0396 f0397 f0398 f0399 f0400 f0401 f0402 f0403 f0404 f0405 f0406 f0407 f0408 f0409 f0410 f0411 f0412 f0413 f0414 f0415 f0416 f0417 f0418 f0419 f0420 f0421 f0422 f0423 f0424 f0425 f0426 f0427">Figure 37</figref> AS.

1225In some embodiments, the interactive application icon switching criteria includes a criterion that the magnitude of a horizontal movement of the first swipe gestures satisfies a predetermined movement threshold. In some embodiments, the predetermined movement threshold varies with the speed of the movement of the contact.

1226While displaying the first interactive application icon in the second area of the display, the device detects an input that activates the first interactive application icon and, in response to detecting the input that activates the first interactive application icon, the device displays a user interface for the first interactive application within the conversation transcript (e.g., displays the first interactive application object) and ceases to display the first interactive application icon (e.g., replacing display of the first interactive application icon with display of an input area for the first interactive application in the second area of the display). For example, device 100-2 displays interactive pizza ordering application object 3735 in conversation transcript 3700, and replaces display of application selection tray 3654, which includes interactive pizza ordering launch icon 3613, in <figref idref="f0391">Figure 37BZ</figref>, with interactive pizza ordering application input area 3731, in <figref idref="f0392">Figure 37CA</figref>.

1227In some embodiments, prior to displaying the first interactive application object within the conversation transcript, the device (5428) displays the messaging user interface including the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between the user of the electronic device and the at least one other user (e.g., of another electronic device) and an application affordance. For example, device 100-1 displays messaging user interface 3500, including conversation transcript 3503 and application affordance 3508, in <figref idref="f0470">Figure 38AQ</figref>.

1228While displaying the messaging user interface, the device detects an input that activates the application affordance (e.g., detecting a tap gesture at a location that corresponds to the application affordance). For example an input including contact 3876 on application affordance 3508, in <figref idref="f0471">Figure 38AR</figref>.

1229In response to detecting the input that activates the application affordance, the device maintains display of at least a portion of the conversation transcript in a first area of the display and displays, in a second area of the display that includes a plurality of launch icons for interactive applications, a launch icon for the first interactive application. For example, device 100-1 maintains display of conversation transcript 3503 and displays application selection tray 3654 in <figref idref="f0472">Figure 38AS</figref>.

1230In some embodiments, where the messaging user interface includes display of an electronic keyboard prior to detecting activation of the application affordance, the display of the plurality of launch icons for interactive applications replaces display of the keyboard. For example, application selection tray 3654, in <figref idref="f0472">Figure 38AS</figref>, replaces digital keyboard in <figref idref="f0471">Figure 38AR</figref>.

1231In some embodiments, where the messaging user interface includes a full-screen display of the conversation transcript prior to detecting activation of the application affordance, the display of the plurality of launch icons for interactive applications replaces a portion of the display of the message transcript. For example, conversation transcript 3700, displayed in full-screen mode in <figref idref="f0354">Figure 37AO</figref>, shrinks to accommodate display of application slide tray 3892 in <figref idref="f0355">Figure 37AP</figref>.

1232While displaying the plurality of launch icons for interactive applications, the device detects an input that activates the launch icon for the first interactive application. For example, an input including contact 3729 on pizza ordering application launch icon 3613, in <figref idref="f0391">Figure 37BZ</figref>.

1233In response to detecting the input that activates the launch icon for the first interactive application (e.g., detecting a tap gesture at a location that corresponds to the launch icon for the first interactive application), the device displays a user interface for the first interactive application within the conversation transcript (e.g., displaying the first interactive application object). For example, device 100-2 displays interactive pizza ordering application object 3735 within transcript 3700, in <figref idref="f0392">Figure 37CA</figref>.

1234In some embodiments, in response to detecting the input that activates the launch icon for the first interactive application, the device replaces (5426) display of the plurality of launch icons for interactive applications with display of an input area for the first interactive application in the second area of the display. For example, interactive pizza ordering application input area 3731, in <figref idref="f0392">Figure 37CA</figref>, replaces display of application selection tray 3654, in <figref idref="f0391">Figure 37BZ</figref>.

1235It should be understood that the particular order in which the operations in <figref idref="f0587 f0589">Figures 54A-54C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 700 described above with respect to <figref idref="f0587 f0589">Figures 54A-54C</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 5400 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5600, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1236In accordance with some embodiments, <figref idref="f0590">Figure 55</figref> shows a functional block diagram of an electronic device 5500 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0590">Figure 55</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1237As shown in <figref idref="f0590">Figure 55</figref>, an electronic device 5500 includes a display unit 5502, a touch-sensitive surface unit 5504, and a processing unit 5510 coupled with the display unit 5502 and the touch-sensitive surface unit 5504. In some embodiments, the processing unit 5510 includes: a display enabling unit 5512, a detecting unit 5514, an updating unit 5516, a sending unit 5518, a maintaining unit 5520, and a replacing unit 5522.

1238The processing unit 5510 is configured to enable display (e.g., with the display enabling unit 5512) of a messaging user interface of a messaging application on the display unit 5502, the messaging user interface including: a conversation transcript, displayed in a first area of the display, of a messaging session between a user of the electronic device and at least one other user, a first interactive application object displayed within the conversation transcript that corresponds to a first interactive application, a message input area, and an input area for the first interactive application, distinct from the message input area, displayed in a second area of the display, the input area for the first interactive application including one or more input affordances. The processing unit 5510 is also configured to detect (e.g., with the detecting unit 5514) an input that activates a first input affordance in the input area for the interactive application.

1239In some embodiments, the processing unit 5510 is further configured to: after detecting the input that activates the first input affordance: update (e.g., with the updating unit 5516) the first interactive application object that corresponds to the first interactive application in accordance with the input that activates the first input affordance; and send (e.g., with the sending unit 5518) information, to one or more electronic devices that correspond to the at least one other user included in the messaging session, that causes update (e.g., with the updating unit 5516) of a corresponding interactive application object that corresponds to the first interactive application displayed within a corresponding conversation transcript of the messaging session.

1240In some embodiments, content posted to the messaging session is displayed within the conversation transcript according to a temporal order in which the content was posted, and the interactive application object is displayed at a position within the conversation transcript associated with the temporal order in which a session of the interactive application was initiated.

1241In some embodiments, the processing unit 5510 is further configured to: enable display (e.g., with the display enabling unit 5512) of synchronous movement of content displayed in a temporal order within the conversation transcript towards an edge of the conversation transcript, the displayed content including the first interactive application object; in accordance with a determination that the first interactive application object is within a predetermined distance from the edge of the conversation transcript, enable display (e.g., with the display enabling unit 5512) of the first interactive application object at a fixed location on the display unit 5502.

1242In some embodiments, the processing unit 5510 is further configured to: while displaying the first interactive application object at the fixed location on the display unit 5502, continue to display synchronous movement of other content displayed in a temporal order within the conversation transcript.

1243In some embodiments, continuing to display synchronous movement of other content displayed in a temporal order with the conversation transcript includes animating other content such that the other content appears to move behind the first interactive application object.

1244In some embodiments, the processing unit 5510 is further configured to: while displaying the first interactive application object at the fixed location on the display unit 5502: detect (e.g., with the detecting unit 5514) a request to close the first interactive application; and, in response to detecting the request to close the first interactive application: cease to display (e.g., with the displaying enabling unit 5512) the first interactive application object at the fixed location on the display unit 5502; and enable display (e.g., with the display enabling unit 5512) of the first interactive application object at a position within the conversation transcript associated with the temporal order in which the session of the interactive application was initiated.

1245In some embodiments, the processing unit 5510 is further configured to: prior to displaying the first interactive application object within the conversation transcript: enable display (e.g., with the display enabling unit 5512) of the messaging user interface including the conversation transcript of the messaging session between the user of the electronic device and the at least one other user and an application affordance; while displaying the messaging user interface, detect (e.g., with the detecting unit 5514) an input that activates the application affordance; in response to detecting the input that activates the application affordance, maintain (e.g., with the maintaining unit 5520) display of at least a portion of the conversation transcript in a first area of the display, and enable display (e.g., with the display enabling unit 5512) of a second interactive application icon, which is one of a plurality of interactive application icons, in a second area of the display; while displaying the second interactive application icon in the second area of the display, detect (e.g., with the detecting unit 5514) a first swipe gesture that includes horizontal movement of a first contact at a location that corresponds to the second area of the display; in accordance with a determination that the first swipe gesture satisfies one or more interactive application icon switching criteria, replace (e.g., with the replacing unit 5522) display of the second interactive application icon with display of a first interactive application icon that corresponds to the first interactive application in the second area of the display; while displaying the first interactive application icon in the second area of the display, detect (e.g., with the detecting unit 5514) an input that activates the first interactive application icon; and, in response to detecting the input that activates the first interactive application icon, enable display (e.g., with the display enabling unit 5512) of a user interface for the first interactive application within the conversation transcript; and cease to display (e.g., with the display enabling unit 5512) the first interactive application icon.

1246In some embodiments, the processing unit 5510 is further configured to: prior to displaying the first interactive application object within the conversation transcript: enable display (e.g., with the display enabling unit 5512) of the messaging user interface including the conversation transcript of the messaging session between the user of the electronic device and the at least one other user and an application affordance; while displaying the messaging user interface, detect (e.g., with the detecting unit 5514) an input that activates the application affordance; in response to detecting the input that activates the application affordance, maintain (e.g., with the maintaining unit 5520) display of at least a portion of the conversation transcript in a first area of the display, and enable display (e.g., with the displaying enabling unit 5512) of, in a second area of the display that includes a plurality of launch icons for interactive applications, a launch icon for the first interactive application; while displaying the plurality of launch icons for interactive applications, detect (e.g., with the detecting unit 5514) an input that activates the launch icon for the first interactive application; and, in response to detecting the input that activates the launch icon for the first interactive application , enable display (e.g., with the display enabling unit 5512) of a user interface for the first interactive application within the conversation transcript.

1247In some embodiments, the processing unit 5510 is further configured to: in response to detecting the input that activates the launch icon for the first interactive application, replace (e.g., with the replacing unit 5522) display of the plurality of launch icons for interactive applications with display of an input area for the first interactive application in the second area of the display.

1248The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1249The operations described above with reference to <figref idref="f0587 f0589">Figures 54A-54C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0590">Figure 55</figref>. For example, detection operation 5420 and 5428 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1250<figref idref="f0591 f0592">Figures 56A-56B</figref> are flow diagrams illustrating a method 5600 of using an interactive application in a messaging application in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 5600 are, optionally, combined and/or the order of some operations is, optionally, changed.

1251As described below, the method 5600 provides an intuitive way to use an interactive application in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when using an interactive application in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to use an interactive application in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1252The device displays (5602) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a first interactive application object displayed within the conversation transcript (e.g., a reservation application object) that corresponds to a first interactive application (e.g., an interactive application for making reservations for a meal, a movie, a hotel, or the like), and a message input area. For example, device 100-2 displays messaging user interface 3500, including conversation transcript 3700, interactive reservations application object 3728, and message input area 3502, in <figref idref="f0328">Figure 37O</figref>.

1253The device detects (5604) a first input while a focus selector is at a location on the touch-sensitive surface that corresponds to the first interactive application object displayed within the conversation transcript (e.g., detect a gesture by a contact on a touch-sensitive display at the location of the first interactive application object, or detect a gesture by a contact on a touch-sensitive surface while a cursor or other pointer is at the location of the first interactive application object). For example, device 100-2 detects an input including contact 3738 on interactive reservations application object 3728 displayed within transcript 3700, in <figref idref="f0329">Figure 37P</figref>.

1254In response to detecting the first input, the device displays (5606) an input area for the first interactive application that is distinct from the message input area, the input area for the first interactive application including one or more input affordances (e.g., radio buttons, text input fields, check boxes, pull down lists, and/or form fields). For example, device 100-2 displays interactive reservations application user interface 3712, including input affordances 3740-1 and 3740-2, in <figref idref="f0330">Figure 37Q</figref>.

1255In some embodiments, display of the input area for the first interactive application in response to detecting the first input (e.g., in response to detecting an input that activates the first interactive application object) replaces (5608) display of the conversation transcript, the first interactive application object, and/or the message input area. For example, display of interactive reservations application user interface 3712 in <figref idref="f0330">Figure 37Q</figref> replaces display of messaging user interface 3500, including conversation transcript 3700, interactive reservations application object 3728, and message input area 3502, in <figref idref="f0329">Figure 37P</figref>.

1256While displaying an input area for the first interactive application, the device detects (5610) one or more inputs on the one or more input affordances. For example, device 100-2 detects inputs including contact 3752 on input affordance 3740-1, in <figref idref="f0337">Figure 37X</figref>, and contact 3754 on input affordance 3740-1, in <figref idref="f0339">Figure 37Z</figref>.

1257After detecting the one or more inputs on the one or more input affordances, the device (5612) updates the first interactive application (e.g., updating fields in a reservation application object in the conversation transcript), sends instructions (e.g., information, instructions, or a representation of an updated interactive application object) to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session to update a corresponding user interface for the first interactive application displayed within a corresponding conversation transcript of the messaging session (e.g., updating a corresponding first interactive application object or other user interface for the first interactive application), and ceases to display of the input area for the first interactive application.

1258For example, device 100-2 updates the reservation time in input affordance 3740-1 in <figref idref="f0340">Figure 37AA</figref>. Device 100-2 also sends information to device 100-1 that the time of the reservation was changed to 8:00 PM, causing device 100-1 to update interactive reservations application object 3728 to show an 8:00 PM reservation time, in <figref idref="f0351">Figure 37AL</figref>, to move display of interactive reservations application object 3728 in transcript 3700 from position 3728-a, in <figref idref="f0350">Figure 37AK</figref>, to position 3728-b in <figref idref="f0351">Figure 37AL</figref>, and to display interactive reservations application archiving icon 3756 within transcript 3700 (e.g., at original position 3728-b of interactive reservations application object 3728). Device 100-2 also ceases to display interactive reservations application user interface in <figref idref="f0342">Figure 37AC</figref>.

1259In some embodiments, the conversation transcript, the first interactive application object, and/or the message input area are redisplayed (e.g., in response to detecting an input that corresponds to a request to cease displaying the input area for the first interactive application. For example, device 100-2 redisplays messaging user interface 3500, including transcript 3700, interactive reservations application object 3728, and message-input area 3502, in <figref idref="f0342">Figure 37AC</figref>.

1260In some embodiments, updating (5614) the first interactive application occurs in response to detecting an input on one of the input affordances. For example, interactive tic-tac-toe application object 3705 is updated (e.g., moves from transcript 3700 position 3705-a, in <figref idref="f0377">Figure 37BL</figref>, to transcript position 3705-b, in <figref idref="f0378">Figure 37BM</figref>) in response to detecting an input including contact 3713 on tic-tac-toe board 3791 (e.g., an input affordance), in <figref idref="f0377">Figure 37BL</figref>

1261In some embodiments, updating (5616) the first interactive application occurs in response to detecting an input that corresponds to a request to cease displaying the input area for the first interactive application. For example, interactive reservations application object 3728 is updated to display an 8:00 reservation in <figref idref="f0342">Figure 37AC</figref> in response to detecting an input including contact 3756 on exit affordance 3714, in <figref idref="f0341">Figure 37AB</figref>, which corresponds to a request to confirm the change to the reservation and close interactive reservations application user interface 3712. In another example, the position of interactive pizza ordering application object 3735 is updated in <figref idref="f0427">Figure 37DJ</figref> in response to an input including contact 3775 on input affordance 3773-3, in <figref idref="f0426">Figure 37DI</figref>, corresponding to a request to order the pizza and close input area 3731 for the interactive pizza ordering application.

1262In some embodiments, sending instructions (5618) (e.g., sending information, instructions, or an updated representation of an interactive application object) to one or more {e.g., second} electronic devices that correspond to the at least one other user included in the messaging session to update a corresponding user interface for the first interactive application occurs in response to detecting an input on one of the input affordances. For example, device 100-2 sends information, at 9:35 AM, that 'X' 3794 was placed on tic-tac-toe board 3791 in response to detecting an input including contact 3713 on tic-tac-toe board 3791 (e.g., an input affordance), in <figref idref="f0377">Figure 37BL</figref>. Device 100-1 receives the information and updates interactive tic-tac-toe application user interface 3782, at 9:35 AM, to display 'X' 3794 on corresponding tic-tac-toe board 3791.

1263In some embodiments, sending instructions (5620) (e.g., sending information, instructions, or an updated representation of an interactive application object) to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session to update a corresponding user interface for the first interactive application occurs in response to detecting an input that corresponds to a request to cease displaying the input area for the first interactive application. For example, device 100-2 sends information, at 9:31 AM, that the reservation has been changed to 8:00 to device 100-1 in response to detecting an input including contact 3756 on exit affordance 3714, in <figref idref="f0341">Figure 37AB</figref>, which corresponds to a request to confirm the change to the reservation and close interactive reservations application user interface 3712. Device 100-1 receives the information, and updates display of interactive reservations application object 3729, in transcript 3700, at 9:31 AM, in <figref idref="f0351">Figure 37AL</figref>.

1264In some embodiments, ceasing display (5622) of the input area for the first interactive application occurs in response to detecting an input on one of the input affordances. For example, device 100-1 ceases to display interactive pizza ordering application input area 3731, in <figref idref="f0427">Figure 37DJ</figref>, in response to an input including contact 3775 on input affordance 3773-3, in <figref idref="f0426">Figure 37DI</figref>, corresponding to a request to order the pizza.

1265In some embodiments, ceasing display (5624) of the input area for the first interactive application occurs in response to detecting an input on an exit affordance. (e.g., detecting a tap gesture on a "done," "save," or "exit" icon or on an area on the display outside of the input area for the first interactive application). For example, device 100-2 ceases to display interactive reservations application user interface 3712, in <figref idref="f0342">Figure 37AC</figref>, in response to detecting an input including contact 3756 on exit affordance 3714, in <figref idref="f0341">Figure 37AB</figref>.

1266In some embodiments, the interactive application is configured to perform a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1267In some embodiments, the interactive application displays a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1268In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches the interactive reservations application within the messaging application. In response to a second (e.g., different) input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches a reservations application outside of the messaging application.

1269In some embodiments, the interactive application is operated separately from a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is operable when a corresponding reservations application operated outside of the messaging application is not running.

1270In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is not operable when a corresponding reservations application operated outside of the messaging application is not running.

1271In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application are stored in a different portion of memory than records of reservations made using a corresponding reservations application operated outside of the messaging application.

1272In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding reservations application operated outside of the messaging application can access the records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application.

1273In some embodiments, the interactive application icon/object displays an identifier for a corresponding application operated separate from the messaging application. For example, in <figref idref="f0324">Figure 37K</figref>, interactive reservations application icon/object 3730 displays a concentric circle symbol that corresponds to a reservations application operated separate from the messaging application.

1274It should be understood that the particular order in which the operations in <figref idref="f0591 f0592">Figures 56A-56B</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5800, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 4500 described above with respect to <figref idref="f0591 f0592">Figures 56A-56B</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 5600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5800, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1275In accordance with some embodiments, <figref idref="f0593">Figure 57</figref> shows a functional block diagram of an electronic device 5700 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0593">Figure 57</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1276As shown in <figref idref="f0593">Figure 57</figref>, an electronic device 5700 includes a display unit 5702, a touch-sensitive surface unit 5704, and a processing unit 5710 coupled with the display unit 5702 and the touch-sensitive surface unit 5704. In some embodiments, the processing unit 5710 includes: a display enabling unit 5712, a detecting unit 5714, an updating unit 5716, a sending unit 5718, and a replacing unit 5720.

1277The processing unit 5710 is configured to enable display (e.g., with the display enabling unit 5712) of a messaging user interface of a messaging application on the display unit 5702, the messaging user interface including: a conversation transcript of a messaging session between a user of the electronic device and at least one other user, a first interactive application object displayed within the conversation transcript that corresponds to a first interactive application, and a message input area. The processing unit 5710 is also configured to detect (e.g., with the detecting unit 5714) a first input while a focus selector is at a location on the touch-sensitive surface unit 5704 that corresponds to the first interactive application object displayed within the conversation transcript. In response to detecting the first input, the processing unit 5710 is configured to enable display (e.g., with the display enabling unit 5712) of an input area for the first interactive application that is distinct from the message input area, the input area for the first interactive application including one or more input affordances. While displaying an input area for the first interactive application, the processing unit 5710 is configured to detect (e.g., with the detecting unit 5714) one or more inputs on the one or more input affordances. After detecting the one or more inputs on the one or more input affordances, the processing unit 5710 is configured to: update (e.g., with the updating unit 5716) the first interactive application; send (e.g., with the sending unit 5718) information to one or more electronic devices that correspond to the at least one other user included in the messaging session that causes updating of a corresponding user interface for the first interactive application displayed within a corresponding conversation transcript of the messaging session; and cease display (e.g., with the display enabling unit 5712) of the input area for the first interactive application.

1278In some embodiments, display of the input area for the first interactive application in response to detecting the first input replaces (e.g., with the replacing unit 5720) display of the conversation transcript, the first interactive application object, and/or the message input area.

1279In some embodiments, updating the first interactive application occurs in response to detecting an input on one of the input affordances.

1280In some embodiments, updating the first interactive application occurs in response to detecting an input that corresponds to a request to cease displaying the input area for the first interactive application.

1281In some embodiments, sending information to one or more electronic devices that correspond to the at least one other user included in the messaging session that causes updating of a corresponding user interface for the first interactive application occurs in response to detecting an input on one of the input affordances.

1282In some embodiments, sending information to one or more electronic devices that correspond to the at least one other user included in the messaging session that causes updating of a corresponding user interface for the first interactive application occurs in response to detecting an input that corresponds to a request to cease displaying of the input area for the first interactive application.

1283In some embodiments, ceasing display of the input area for the first interactive application occurs in response to detecting an input on one of the input affordances.

1284In some embodiments, ceasing display of the input area for the first interactive application occurs in response to detecting an input on an exit affordance.

1285The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1286The operations described above with reference to <figref idref="f0591 f0592">Figures 56A-56B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0593">Figure 57</figref>. For example, detection operations 5604 and 5610 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1287<figref idref="f0594">Figure 58</figref> is a flow diagram illustrating a method 5800 of enabling use of an interactive application in a messaging application in accordance with some embodiments. The method 5800 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 5800 are, optionally, combined and/or the order of some operations is, optionally, changed.

1288As described below, the method 5800 provides an intuitive way to enable use of an interactive application in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when enabling use of an interactive application in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to enable use of an interactive application in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1289In some embodiments, the device has one or more processors, memory, and a display, where a messaging application and a plurality of other applications are stored in the memory, and a respective application in the plurality of other applications has a normal mode for normal operation on the electronic device (e.g., as a standalone application, separate from the messaging application) and an embedded mode for operation within the messaging application on the electronic device;

1290In some embodiments, the electronic device includes a touch-sensitive surface, e.g., a track-pad or touch-sensitive display. In some embodiments, the electronic device includes one or more sensors configured to detect intensities of contacts on the touch-sensitive surface.

1291The device (5802) displays a plurality of toggle affordances, where a respective toggle affordance in the plurality of toggle affordances has a corresponding application in the plurality of other applications stored in the memory, the respective toggle affordance has a first state that enables display of a respective launch icon, within the messaging application, for operation of the corresponding application in the embedded mode within the messaging application, the respective toggle affordance has a second state that prevents display of the respective launch icon, within the messaging application, to prevent operation of the corresponding application in the embedded mode within the messaging application, and the plurality of toggle affordances include a first toggle affordance for a first application that is displayed in the first state and a second toggle affordance for a second application that is displayed in the second state.

1292While displaying the plurality of toggle affordances, the device detects (5804) a first user input at a first location that corresponds to the first toggle affordance (e.g., detecting a tap or swipe gesture at a location on a touch-sensitive surface that corresponds to a location of the first toggle affordance on the display).

1293In response to detecting the first user input at the first location that corresponds to the first toggle affordance, the device (5806) changes the first toggle affordance from the first state to the second state, and prevents display of a corresponding launch icon for the first application in the messaging application.

1294In some embodiments, while displaying the plurality of toggle affordances, the device (5808) detects a second user input at a second location that corresponds to the second toggle affordance (e.g., detecting a tap or swipe gesture at a location on a touch-sensitive surface that corresponds to a location of the second toggle affordance on the display) and, in response to detecting the second user input at the second location that corresponds to the second toggle affordance, changes the second toggle affordance from the second state to the first state and enables display of a corresponding launch icon for the second application in the messaging application.

1295It should be understood that the particular order in which the operations in <figref idref="f0594">Figure 58</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 6000, 6200, 6400, 6600, 6800, and 7000) are also applicable in an analogous manner to method 5800 described above with respect to <figref idref="f0594">Figure 58</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described above with reference to method 5800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 6000, 6200, 6400, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1296In accordance with some embodiments, <figref idref="f0595">Figure 59</figref> shows a functional block diagram of an electronic device 5900 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0595">Figure 59</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1297As shown in <figref idref="f0595">Figure 59</figref>, an electronic device 5900 includes a display unit 5902, a touch-sensitive surface unit 5904, and a processing unit 5910 coupled with the display unit 5902 and the touch-sensitive surface unit 5904. In some embodiments, a messaging application and a plurality of other applications are stored in memory of the electronic device 5900, and a respective application in the plurality of other applications has a normal mode for normal operation on the electronic device 5900 and an embedded mode for operation within the messaging application on the electronic device 5900. In some embodiments, the processing unit 5910 includes: a display enabling unit 5912, a detecting unit 5914, and a changing unit 5916.

1298The processing unit 5910 is configured to enable display (e.g., with the display enabling unit 5912) of a plurality of toggle affordances. In some embodiments, a respective toggle affordance in the plurality of toggle affordances has a corresponding application in the plurality of other applications stored in the memory; the respective toggle affordance has a first state that enables display of a respective launch icon, within the messaging application, for operation of the corresponding application in the embedded mode within the messaging application; the respective toggle affordance has a second state that prevents display of the respective launch icon, within the messaging application, to prevent operation of the corresponding application in the embedded mode within the messaging application; the plurality of toggle affordances include a first toggle affordance for a first application that is displayed in the first state and a second toggle affordance for a second application that is displayed in the second state. While displaying the plurality of toggle affordances, the processing unit 5910 is configured to detect (e.g., with the detecting unit 5914) a first user input at a first location that corresponds to the first toggle affordance. In response to detecting the first user input at the first location that corresponds to the first toggle affordance, the processing unit 5910 is configured to change (e.g., with the changing unit 5916) the first toggle affordance from the first state to the second state, and prevent display (e.g., with the display enabling unit 5912) of a corresponding launch icon for the first application in the messaging application.

1299In some embodiments, while displaying the plurality of toggle affordances, the processing unit 5910 is further configured to detect (e.g., with the detecting unit 5914) a second user input at a second location that corresponds to the second toggle affordance; and, in response to detecting the second user input at the second location that corresponds to the second toggle affordance, change (e.g., with the changing unit 5916) the second toggle affordance from the second state to the first state, and enable display (e.g., with the display enabling unit 5912) of a corresponding launch icon for the second application in the messaging application.

1300The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1301The operations described above with reference to <figref idref="f0594">Figure 58</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0595">Figure 59</figref>. For example, display operation 5802 and detection operation 5804 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1302<figref idref="f0596 f0599">Figures 60A-60D</figref> are flow diagrams illustrating a method 6000 of navigating within a messaging application having associated applications in accordance with some embodiments. The method 6000 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 6000 are, optionally, combined and/or the order of some operations is, optionally, changed.

1303As described below, the method 5000 provides an intuitive way to navigate within a messaging application having associated applications. The method reduces the number, extent, and/or nature of the inputs from a user when navigating within a messaging application having associated applications, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to navigate within a messaging application having associated applications faster and more efficiently conserves power and increases the time between battery charges.

1304The device displays (6002) a messaging user interface (e.g., of a messaging application) on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a message-input area, a digital image affordance, a digital touch affordance, and an application affordance. In some embodiments, the messaging user interface also includes a keyboard, e.g., displayed in a second area of the display.

1305For example, in <figref idref="f0428">Figure 38A</figref>, device 100-1 displays messaging user interface 3500 on touch screen 112. Messaging user interface 3500 includes conversation transcript 3503, digital image affordance 3504, digital canvas affordance 3506, application affordance 3508, and message-input area 3502. In <figref idref="f0475">Figure 38AV</figref>, messaging user interface also includes digital keyboard 3501.

1306In some embodiments, the messaging user interface also includes (6004) a microphone affordance, configured to enable sound recording on the electronic device upon activation. For example, microphone affordance 3802 in <figref idref="f0428">Figure 38A</figref>.

1307In some embodiments, the messaging user interface also includes (6006) at least one avatar corresponding to a first other user included in the messaging session, configured to enable the electronic device to display a menu that contains activatable menu items associated with the at least one avatar overlaid on the messaging user interface when activated.

1308For example, in <figref idref="f0428">Figures 38A</figref> and <figref idref="f0476">38AW</figref>, conversation transcript 3503 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100-1 and other users included in the messaging session. Each of the other users included in the messaging transcript are represented by an avatar (e.g., avatar 3510 for "Abe") displayed in stack of avatars 3892. Upon activation of Abe's avatar 3510, by an input including contact 3880 in <figref idref="f0476">Figure 38AW</figref>, the device displays menu 3882 containing activatable menu items 3884, in <figref idref="f0477">Figure 38AX</figref>.

1309In some embodiments, the menu that contains activatable menu items associated with the at least one avatar includes (6008) a menu item that when activated initiates a digital touch action with the first other user (e.g., menu item 3884-5 in <figref idref="f0477">Figure 38AX</figref>), a menu item that when activated initiates messaging with only the first other user (e.g., selecting a messaging menu item causes the electronic device to display a private messaging user interface between the user of the electronic device and the first other user) (e.g., menu item 3884-3 in <figref idref="f0477">Figure 38AX</figref>), a menu item that when activated initiates an email with the first other user (e.g., menu item 3884-4 in <figref idref="f0477">Figure 38AX</figref>), a menu item that when activated initiates a call with the first other user (e.g., menu item 3884-1 in <figref idref="f0477">Figure 38AX</figref>), a menu item that when activated initiates a video conference with the first other user (e.g., menu item 3884-2 in <figref idref="f0477">Figure 38AX</figref>), and/or a menu item that when activated initiates a payment action with the first other user (e.g., menu item 3884-6 in <figref idref="f0477">Figure 38AX</figref>).

1310While displaying the messaging user interface, the device detects (6010) a first input on the touch sensitive surface (e.g., for an electronic device with a touch sensitive display, detecting a tap gesture). For example an input including one of contact 3804 on digital image affordance 3504, in <figref idref="f0429">Figure 38B</figref>, contact 3852 on digital canvas affordance 3506, in <figref idref="f0454">Figure 38AA</figref>, and contact 3868 on application affordance 3508, in <figref idref="f0463">Figure 38AJ</figref>.

1311In response to detecting the first input, the device (6012): in accordance with a determination that the first input is made while a focus selector is at a location in the messaging user interface that corresponds to the digital image affordance, displays a plurality of digital images within the messaging user interface (e.g., digital images 3514 and 3518 in digital image tray 3806 in <figref idref="f0430">Figure 38C</figref>); in accordance with a determination that the first input is made while a focus selector is at a location in the messaging user interface that corresponds to the digital canvas affordance, displaying a digital drawing canvas within the messaging user interface (e.g., digital drawing canvas 3858 in digital touch tray 3854 in <figref idref="f0461">Figure 38AH</figref>); and in accordance with a determination that the first input is made while a focus selector is at a location in the messaging user interface that corresponds to the application affordance, displaying one or more launch icons for an (e.g., interactive) application within the messaging user interface (e.g., application launch icon 3708 in application swipe tray 3892 in <figref idref="f0464">Figure 38AK</figref> or application launch icons 3601, 3603, 3605, 3607, 3609, 3611, 3613, and 3615 in application selection tray 3654 in <figref idref="f0467">Figure 38AN</figref>).

1312In some embodiments, displaying the plurality of digital images within the messaging user interface includes (6014): in accordance with a determination that the messaging user interface included display of a keyboard at the time the first input was detected, replacing display of the keyboard with the display of the plurality of digital images, the plurality of digital images including a live preview image from the digital camera, and in accordance with a determination that the messaging user interface did not include display of a keyboard at the time the first input was detected, displaying the conversation transcript in a first area of the display and displaying the plurality of digital images in a second area of the display, the plurality of digital images including a live preview image from the digital camera.

1313For example, in <figref idref="f0430">Figure 38C</figref>, the size of conversation transcript 3503 is reduced, with respect to the size of conversation transcript 3503 in <figref idref="f0429">Figure 38B</figref>, to accommodate display of digital image tray 3806, including live preview image 3514 from optical sensor 164 and previously captured digital images 3518.

1314In another example, display of digital keyboard 3501, in <figref idref="f0451">Figure 38X</figref>, is replaced by display of digital image tray 3806, including live preview image 3514 from optical sensor 164 and previously captured digital images 3518, in <figref idref="f0452">Figure 38Y</figref>.

1315In some embodiments, replacing display of the keyboard includes displaying the plurality of digital images over the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the plurality of digital images where the keyboard had been displayed (e.g., as in <figref idref="f0451 f0452">Figures 38X-38Y</figref>).

1316In some embodiments, the plurality of digital images is a scrollable array of digital images. For example, digital image tray 3806 is scrolled in <figref idref="f0432">Figure 38E</figref> to reveal additional digital images 3518-6 and 3518-7.

1317In some embodiments, the plurality of digital images includes a recently shared image, a recently received image, an image including a participant in the conversation (e.g., as identified by facial recognition), a real-time image from a forward-facing digital camera in the device, or a real-time image from a backwards-facing digital camera in the device.

1318In some embodiments, the plurality of digital images consists of the live preview image from the digital camera (e.g., live preview image 3514 in <figref idref="f0430">Figure 38C</figref>) and a plurality of digital images captured during the messaging session.

1319In some embodiments, where the conversation transcript was maximized at the time the second input was detected, display of the conversation transcript is partially replaced by display of the plurality of digital images. For example, display of conversation transcript 3503 is partially replaced by digital image tray 3806 in <figref idref="f0430">Figure 38C</figref>.

1320In some embodiments, while displaying the plurality of digital images, the device (6016) detects an input that selects a digital image in the plurality of digital images (e.g., an input including contact 3512 on live preview image 3514 in <figref idref="f0237">Figure 35D</figref>) and, after detecting the input that selects a digital image in the plurality of digital images, displays the selected digital image in the conversation transcript (e.g., display of captured digital image 3518-5 in conversation transcript 3503 in <figref idref="f0240">Figures 35G</figref> and <figref idref="f0242">35I</figref>) and transmitting a representation of the selected digital image to one or more electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display the representation of the selected digital image in a conversation transcript that corresponds to the messaging session.

1321In some embodiments, the digital image is automatically posted to the messaging session upon selection. For example, digital image 3518-5 is automatically posted to the messaging session in <figref idref="f0242">Figure 35I</figref> in response to an input including contact 3524 in <figref idref="f0241 f0242">Figures 35H-35I</figref>.

1322In some embodiments, the digital image is displayed in the message input area and the user posts the image to the messaging session (e.g., by activating a send icon with a tap gesture). For example, digital image 3518-5 is displayed in message-input area 3502, in <figref idref="f0238">Figure 35E</figref>, in response to detecting an input including contact 3512, in <figref idref="f0237">Figure 35D</figref>. Digital image 3518-5 is then posted to the messaging session, in <figref idref="f0240">Figure 35G</figref>, in response to detecting an input including contact 3522 on posting affordance 3520, in <figref idref="f0239">Figure 35F</figref>.

1323In some embodiments, the device (6018) detects an input that selects the live image displayed within the plurality of digital images (e.g., for an electronic device with a touch sensitive display, detecting a tap gesture on the live image) and, in response to detecting that input that selects the live image, captures a digital image with the digital camera, while maintaining display of the conversation transcript. For example, in response to detecting an input including contact 3512 on capture affordance 3516 displayed over live preview image 3514, in <figref idref="f0237">Figure 35D</figref>, the device captures digital image 3518-5, while maintaining display of conversation transcript 3503, in <figref idref="f0238">Figure 35E</figref>.

1324In some embodiments, after capturing the digital image, the device (6020) displays the digital image captured by the digital camera in the conversation transcript and transmits a representation of the captured digital image to one or more electronic devices that correspond to the at least one other user included in the messaging session, where the one or more electronic devices display the representation of the captured digital image in a conversation transcript that corresponds to the messaging session. For example, captured image 3518-5 is displayed in conversation transcript 3503 in <figref idref="f0240">Figures 35G</figref> and <figref idref="f0242">35I</figref>.

1325In some embodiments, the captured image is automatically posted to the messaging session upon selection of the live image. For example, captured digital image 3518-5 is automatically posted to the messaging session in <figref idref="f0242">Figure 35I</figref> in response to an input including contact 3524 in <figref idref="f0241 f0242">Figures 35H-35I</figref>.

1326In some embodiments, the captured image is displayed in the message input area and the user posts the image to the messaging session (e.g., by activating a send icon with a tap gesture). For example, captured digital image 3518-5 is displayed in message-input area 3502, in <figref idref="f0238">Figure 35E</figref>, in response to detecting an input including contact 3512, in <figref idref="f0237">Figure 35D</figref>. Captured digital image 3518-5 is then posted to the messaging session, in <figref idref="f0240">Figure 35G</figref>, in response to detecting an input including contact 3522 on posting affordance 3520, in <figref idref="f0239">Figure 35F</figref>.

1327In some embodiments, displaying the digital drawing canvas within the messaging user interface includes (6022), in accordance with a determination that the messaging user interface included display of a keyboard at the time the first input was detected, replacing display of the keyboard with the display of the digital drawing canvas and, in accordance with a determination that the messaging user interface did not include display of a keyboard at the time the first input was detected, displaying the conversation transcript in a first area of the display and displaying the plurality of digital touch actions in a second area of the display.

1328For example, in <figref idref="f0455">Figure 38AB</figref>, the size of conversation transcript 3503 is reduced, with respect to the size of conversation transcript 3503 in <figref idref="f0454">Figure 38AA</figref>, to accommodate display of digital touch tray 3854, including digital drawing canvas 3858.

1329In another example, display of digital keyboard 3501, in <figref idref="f0434">Figure 38G</figref>, is replaced by display of digital touch tray 3854, including digital drawing canvas 3858, in <figref idref="f0461">Figure 38AH</figref>.

1330In some embodiments, replacing display of the keyboard includes displaying the digital drawing canvas over the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the digital drawing canvas where the keyboard had been displayed (e.g., as illustrated in <figref idref="f0460 f0461">Figures 38AG-38AH</figref>).

1331In some embodiments, where the conversation transcript was maximized at the time the second input was detected, display of the conversation transcript is partially replaced by display of the digital drawing canvas (e.g., as illustrated in <figref idref="f0506 f0507">Figures 38AA-38AB</figref>).

1332In some embodiments, displaying the one or more launch icons for an (e.g., interactive) application within the messaging user interface includes (6024): in accordance with a determination that the messaging user interface included display of a keyboard at the time the first input was detected, replacing display of the keyboard with the display of the one or more launch icons for an (e.g., interactive) application and, in accordance with a determination that the messaging user interface did not include display of a keyboard at the time the first input was detected, displaying the conversation transcript in a first area of the display and displaying the one or more launch icons for an (e.g., interactive) application in a second area of the display.

1333For example, in <figref idref="f0464">Figure 38AK</figref>, the size of conversation transcript 3503 is reduced, with respect to the size of conversation transcript 3503 in <figref idref="f0463">Figure 38AJ</figref>, to accommodate display of application swipe tray 3893, including interactive reservations application launch icon 3708.

1334In another example, display of digital keyboard 3501, in <figref idref="f0471">Figure 38AR</figref>, is replaced by display of application selection tray 3654, including application launch icons 3601, 3603, 3605, 3607, 3609, 3611, 3613, and 3615, in <figref idref="f0472">Figure 38AS</figref>.

1335In some embodiments, replacing display of the keyboard includes displaying the one or more launch icon over the keyboard. In some embodiments, replacing display of the keyboard includes ceasing to display the keyboard and displaying the one or more launch icon where the keyboard had been displayed (e.g., as illustrated in <figref idref="f0471 f0472">Figures 38AR-38AS</figref>).

1336In some embodiments, the one or more launch icon is a single launch icon in a scrollable list of launch icons (e.g., interactive reservations application launch icon 3708 in application swipe tray 3892 in <figref idref="f0356">Figure 37AQ</figref>).

1337In some embodiments, the one or more launch icon is a plurality of launch icons, e.g., displayed in a mini springboard (e.g., application launch icons 3601, 3603, 3605, 3607, 3609, 3611, 3613, and 3615 displayed in application selection tray 3654 in <figref idref="f0467">Figure 38AN</figref>).

1338In some embodiments, where the conversation transcript was maximized at the time the second input was detected, display of the conversation transcript is partially replaced by display of the one or more launch icon (e.g., as illustrated in <figref idref="f0463 f0464">Figures 38AJ-38AK</figref>).

1339In some embodiments, while displaying the one or more launch icons for an (e.g., interactive) application, the device (6026) detects an input that activates a launch icon in the one or more launch icons for an (e.g., interactive) application (e.g., an input including one of contact 3710 in <figref idref="f0319">Figure 37F</figref>, contact 3776 in <figref idref="f0359">Figure 37AT</figref>, and contact 3729 in <figref idref="f0391">Figure 37BZ</figref>).

1340In some embodiments, after detecting the input that activates the launch icon in the one or more launch icons for an (e.g., interactive) application, the device displays a first input area for an (e.g., interactive) application corresponding to the activated launch icon the (e.g., interactive) application that is distinct from the message input area, the input area for the first interactive application including one or more input affordances (e.g., radio buttons, text input fields, check boxes, pull down lists, and/or form fields. For example, interactive reservations application user interface 3712 in <figref idref="f0320">Figure 37G</figref>, interactive tic-tac-toe application input area 3778 in <figref idref="f0361">Figure 37AV</figref>, interactive tic-tac-toe application user interface 3784 <figref idref="f0362">Figure 37AW</figref>, or interactive pizza ordering application input area 3731 in <figref idref="f0392">Figure 37CA</figref>.

1341In some embodiments, the first input area is displayed over/replaces display of a portion of the messaging user interface. (e.g., interactive reservations application user interface 3712 in <figref idref="f0320">Figure 37G</figref>).

1342In some embodiments, the first input area replaces display of the one or more launch icons for an (e.g., interactive) application (e.g., interactive tic-tac-toe application input area 3778 in <figref idref="f0361">Figure 37AV</figref> or interactive pizza ordering application input area 3731 in <figref idref="f0392">Figure 37CA</figref>).

1343In some embodiments, the first input area is displayed over/replaces display of the entire messaging user interface (e.g., interactive reservations application user interface 3712 in <figref idref="f0320">Figure 37G</figref> or interactive tic-tac-toe application user interface 3784 <figref idref="f0362">Figure 37AW</figref>).

1344In some embodiments, the first input area for the (e.g., interactive) application is a menu including choices as to how to operate a session of the (e.g., interactive) application (e.g., play tic-tac-toe as X or O). For example, interactive tic-tac-toe application input area 3778 in <figref idref="f0361">Figure 37AV</figref>.

1345In some embodiments, the first input area for the (e.g., interactive) application is a user interface for the (e.g., interactive) application.

1346In some embodiments, the device displays a first (e.g., interactive) application object within the conversation transcript that corresponds to the (e.g., interactive) application corresponding to the activated launch icon. For example, interactive reservations application object 3728, in <figref idref="f0322">Figure 37I</figref>, corresponding to an interactive reservations application launched from launch icon 3708, in <figref idref="f0319">Figure 37F</figref>. Another example is interactive tic-tac-toe application object 3728, in <figref idref="f0362">Figure 37AW</figref>, corresponding to an interactive tic-tac-toe application launched from launch icon 3774 in <figref idref="f0359">Figure 37AT</figref>. Another example is interactive pizza ordering application object 3725, in <figref idref="f0392">Figure 37CA</figref>, corresponding to an interactive pizza ordering application launched from launch icon 3613, in <figref idref="f0391">Figure 37BZ</figref>.

1347In some embodiments, where display of at least a portion of the conversation transcript is maintained while the first input area for the (e.g., interactive) application is displayed, the interactive application object is displayed immediately in the conversation transcript (e.g., interactive tic-tac-toe application object 3728, in <figref idref="f0362">Figure 37AW</figref> and interactive pizza ordering application object 3725, in <figref idref="f0392">Figure 37CA</figref>).

1348In some embodiments, where display of the first input area for the (e.g., interactive) application replaces display of the conversation transcript, the interactive application object is displayed after display of the first input area is terminated (e.g., interactive reservations application object 3728, in <figref idref="f0322">Figure 37I</figref>).

1349In some embodiments, transmitting a representation of a second (e.g., interactive) application object that corresponds to the (e.g., interactive) application corresponding to the activated launch icon to one or more electronic devices that correspond to the at least one other user included in the messaging session, where the one or more electronic devices display the representation of the second (e.g., interactive) application object in a conversation transcript that corresponds to the messaging session.

1350For example, device 100-2 displays interactive reservations application object 3728, in <figref idref="f0324">Figure 37K</figref>, in response to receiving information from device 100-1 that a session of the corresponding interactive reservations application was initiated within the messaging session corresponding to conversation transcript 370.

1351In another example, device 100-2 displays interactive tic-tac-toe application object 3705, in <figref idref="f0371">Figure 37BF</figref>, in response to receiving information from device 100-1 that a session of the corresponding interactive tic-tac-toe application was initiated within the messaging session corresponding to conversation transcript 3700.

1352In another example, device 100-1 displays interactive pizza ordering application object 3735, in <figref idref="f0409">Figure 37CR</figref>, in response to receiving information from device 100-2 that a session of the corresponding pizza ordering application was initiated with the messaging session corresponding to conversation transcript 3700.

1353In some embodiments, the second (e.g., interactive) application object is the same as the first (e.g., interactive) application object, e.g., for a standard messages application. In some embodiments, the second (e.g., interactive) application object is different from the first (e.g., interactive) application object, e.g., for a third party messages application that the other user may need to download to use.

1354In some embodiments, the interactive application is configured to perform a subset (e.g., less than all) of the functions of a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1355In some embodiments, the interactive application displays a portion (e.g., less than all) of the content displayed by a corresponding application operated separate from the messaging application. For example, in some embodiments, an interactive reservations application operated within a messaging application is be configured to allow making reservations but not configured to allow users to comment on a restaurant. In contrast, the corresponding reservation application operable outside of the messaging application is configured to allow making reservations and commenting on a restaurant.

1356In some embodiments, the interactive application causes the device to launch a corresponding application operated separate from the messaging application upon detection of a predefined input. For example, in response to a first input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches the interactive reservations application within the messaging application. In response to a second (e.g., different) input (e.g., a tap, press, deep press, long-press, or multi-finger gesture) on interactive reservations application icon 3728 in <figref idref="f0329">Figure 37P</figref>, the device launches a reservations application outside of the messaging application.

1357In some embodiments, the interactive application is operated separately from a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is operable when a corresponding reservations application operated outside of the messaging application is not running.

1358In some embodiments, the interactive application is operated in conjunction with a corresponding application operated separate from the messaging application. For example, the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> is not operable when a corresponding reservations application operated outside of the messaging application is not running.

1359In some embodiments, the interactive application has a dedicated portion of the memory for temporary storage that is different from a dedicated portion of the memory for temporary storage for a corresponding application operated separate from the messaging application. For example, in some embodiments, records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application are stored in a different portion of memory than records of reservations made using a corresponding reservations application operated outside of the messaging application.

1360In some embodiments, the corresponding application operated separate from the messaging application is configured to access the dedicated portion of memory for temporary storage for the interactive application. For example, in some embodiments, the corresponding reservations application operated outside of the messaging application can access the records of reservations made using the interactive reservations application launched in response to activation of icon 3728 in <figref idref="f0329">Figure 37P</figref> and operated within the messaging application.

1361In some embodiments, the interactive application icon/object displays an identifier for a corresponding application operated separate from the messaging application. For example, in <figref idref="f0324">Figure 37K</figref>, interactive reservations application icon/object 3730 displays a concentric circle symbol that corresponds to a reservations application operated separate from the messaging application.

1362In some embodiments, while displaying the message-input area, the device (6028) detecting a second input that activates the message-input area (e.g., an input including one of contact 3872, in <figref idref="f0467">Figure 38AN</figref>, contact 3878, in <figref idref="f0474">Figure 38AU</figref>, and contact 3528 in <figref idref="f0245">Figure 35L</figref>).

1363In some embodiments, in response to detecting the input that activates the message-input area, in accordance with a determination that the messaging user interface included display of a keyboard and did not include display of the three activatable affordances at the time the second input was detected, the device displays a prompt within the message-input area.

1364In some embodiments, in response to detecting the input that activates the message-input area, in accordance with a determination that the messaging user interface included display of a keyboard and the three activatable affordances at the time the second input was detected, the device: ceases to display the three activatable affordances, displays the application expansion affordance, expands display of the message input-area, and displays a prompt within the message-input area.

1365In some embodiments, in response to detecting the input that activates the message-input area, in accordance with a determination that the messaging user interface did not include display of a keyboard and included display of the three activatable affordances at the time the second input was detected, the device: ceases to display the three activatable affordances, displays the application expansion affordance, expands display of the message input-area, displays a prompt within the message-input area, and displays a keyboard.

1366In some embodiments, in response to detecting the input that activates the message-input area, in accordance with a determination that the messaging user interface did not include display of a keyboard and included display of the three activatable affordances at the time the second input was detected, the device: displays a prompt within the message-input area, and displays a keyboard.

1382The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1383The operations described above with reference to <figref idref="f0596 f0599">Figures 60A-60D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0600">Figure 61</figref>. For example, display operation 6002 and detection operation 6010 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Adding and manipulating stickers

1384<figref idref="f0601 f0603">Figures 62A-62C</figref> are flow diagrams illustrating a method 6200 of adding a sticker to a messaging transcript in accordance with some embodiments. The method 6200 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 6200 are, optionally, combined and/or the order of some operations is, optionally, changed.

1385As described below, the method 6200 provides an intuitive way to add a sticker to a messaging transcript. The method reduces the number, extent, and/or nature of the inputs from a user when adding a sticker to a messaging transcript, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to add a sticker to a messaging transcript faster and more efficiently conserves power and increases the time between battery charges.

1386The device displays (6202) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a plurality of electronic stickers (e.g., a sticker pack displayed in a second area of the display), and a message-input area. For example, in <figref idref="f0482">Figure 39C</figref>, device 100-1 displays messaging user interface 3500, including conversation transcript 3700, sticker pack 3892 with electronic stickers 3906, 3908, and 3910, and message-input area 3502.

1387While displaying the messaging user interface, the device detects (6204) a first drag gesture {e.g., by a first contact on a touch-sensitive surface} that starts while a focus selector is at a first location in the messaging user interface that corresponds to a first electronic sticker in the plurality of electronic stickers, the first drag gesture moving the focus selector in a first direction; (e.g., detect a drag gesture by a contact on a touch-sensitive display that starts at the first electronic sticker and moves in a first direction, or detect a drag gesture by a contact on a touch-sensitive surface that starts while a cursor or other pointer is at the first electronic sticker on the display and moves the pointer in a first direction on the display). For example, device 100-1 detects a drag gesture including movement 3918 of contact 3906 from position 3906-a, over electronic snowman sticker 3906 in <figref idref="f0487">Figure 39H</figref>, to position 3906-b, in <figref idref="f0488">Figure 39I</figref>. In another example, device 100-1 detects a drag gesture including movement 3922 of contact 3920 from position 3920-a, over electronic sled sticker 3910 in <figref idref="f0490">Figure 39K</figref>, to position 3920-b, in <figref idref="f0491">Figure 39L</figref>. In another example, device 100-1 detects a drag gesture including movement 3926 of contact 3925 from position 3924-a, over electronic snowflake sticker 3908 in <figref idref="f0493">Figure 39N</figref>, to position 3924-b, in <figref idref="f0494">Figure 39O</figref>.

1388The device moves (6206) the first electronic sticker in the first direction in accordance with the movement of the first drag gesture. For example, electronic snowman sticker moves from location 3906-a, in <figref idref="f0487">Figure 39H</figref>, to position 3906-b, in <figref idref="f0488">Figure 39I</figref>, in accordance with movement 3918. In another example, electronic sled sticker 3910 moves from position 3910-a, in <figref idref="f0490">Figure 39K</figref>, to position 3910-b, in <figref idref="f0491">Figure 39L</figref>, in accordance with movement 3922. In another example, electronic snowflake sticker 3908 moves from position 3908-a, in <figref idref="f0493">Figure 39N</figref>, to position 3908-c, in <figref idref="f0494">Figure 39O</figref>, in accordance with movement 3926.

1389In some embodiments, the plurality of electronic stickers is a plurality of objects contained within a digital image (e.g., a TV or movie frame, a digital comic illustration, a frame from a digital video, or other digital image), where (6208): the first electronic sticker corresponds to an object displayed at the first location at the start of the first drag gesture (e.g., tapping on any object within the digital image creates a digital sticker of that object), and moving the first electronic sticker includes displaying an animation of peeling the first electronic sticker from the digital image (e.g., it appears that the user is peeling the first electronic sticker away from the digital image).

1390The device detects (6210) termination of the first drag gesture while the focus selector is at a second location in the messaging user interface (e.g., while a contact on a touch-sensitive display is at the second location, or while a cursor or other pointer is at the second location). For example, device 100-1 detects termination of a drag gesture when contact 3916 is at position 3916-b in <figref idref="f0488">Figure 39I</figref> (e.g., lift-off of contact 3916, as illustrated in <figref idref="f0489">Figure 39J</figref>). In another example, device 100-1 detects termination of a drag gesture when contact 3920 is at position 3920-b in <figref idref="f0491">Figure 39L</figref> (e.g., lift-off of contact 3920, as illustrated in <figref idref="f0492">Figure 39M</figref>). In another example, device 100-1 detects termination of a drag gesture when contact 3924 is at position 3924-b in <figref idref="f0494">Figure 39O</figref> (e.g., lift-off of contact 3924, as illustrated in <figref idref="f0495">Figure 39P</figref>).

1391In response to detecting termination of the first drag gesture (e.g., detecting lift-off the contact in the drag gesture), the device: in accordance with a determination that the second location is within the conversation transcript (e.g., the sticker was dragged from the tray into the conversation transcript), places (6212) the electronic sticker in the conversation transcript at a location based on the second location. For example, in <figref idref="f0489">Figure 39J</figref>, electronic snowman sticker 3906 is placed in conversation transcript 3700 because the drag gesture terminated within the transcript (e.g., at position 3916-b). In another example, in <figref idref="f0495">Figure 39P</figref>, electronic snowflake sticker 3908 is placed in conversation transcript 3700 because the drag gesture terminated within the transcript (e.g., at position 3916-b).

1392In response to detecting termination of the first drag gesture (e.g., detecting lift-off the contact in the drag gesture), the device: in accordance with a determination that the second location in not within the conversation transcript (e.g., the sticker was not dragged into the conversation transcript), ceases (6212) to display the electronic sticker at the second location on the display. E.g., when the sticker is not dragged all the way to the conversation transcript, termination of the gesture causes the sticker to return to the sticker pack. For example, in <figref idref="f0492">Figure 39M</figref>, device 100-1 ceases displaying electronic sled sticker 3910 at position 3910-b in response to detecting lift-off of contact 3920 (e.g., termination of the drag gesture) while outside of conversation transcript 3700 (e.g., at position 3920-b),

1393In some embodiments, the electronic device differentiates between an input that allows the user to place the sticker at a user-selected location in the transcript and an input that places the sticker at a default location within the transcript. For example, a drag gesture places the sticker at a user-selection location within the transcript (e.g., snowman sticker 3906 is dragged to, and placed at, position 3906-b in <figref idref="f0487 f0489">Figures 39H-39J</figref>, while a stationary gesture (such as a tap, light press, or deep press) places the sticker in the transcript at a default next location designated for a user message (e.g., with or without a surrounding message bubble). For example, snowflake sticker 3908 is placed in transcript 3700 at position 3908-a, in <figref idref="f0486">Figure 39G</figref>, corresponding to the next temporal position within the conversation transcript, after detecting a tap gesture on the sticker, including contact 3912 in <figref idref="f0483">Figure 39D</figref>.

1394In some embodiments, the device displays a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a plurality of electronic stickers (e.g., a sticker pack displayed in a second area of the display), and a message-input area. While displaying the messaging user interface, the device detects a first user input at a location corresponding to display of a first electronic sticker. In response to detecting the first user input: in accordance with a determination that the first user input includes a drag gesture starting at the location corresponding to display of the first electronic sticker and ending at a location corresponding to display of the conversation transcript, placing the electronic sticker in the conversation transcript (e.g., dragging the sticker into the conversation transcript). For example, snowman sticker 3906 is dragged into conversation transcript 3700 in <figref idref="f0489">Figures 39J-39J</figref>. In accordance with a determination that the first user input satisfies tap gesture criteria (e.g., detection of initiation and termination of a user contact, having a characteristic intensity that does not reach a predefined intensity threshold, at a substantial same location), displaying the electronic sticker in the message-input area (e.g., which allows the user to post the sticker to the transcript at a location corresponding to the next message). For example, snowflake sticker 3908 is tapped on and placed in message-input area 3502 in <figref idref="f0483 f0485">Figures 39D-39F</figref>.

1395In some embodiments, the location based on the second location is the second location (6214). For example, the sticker is placed in the transcript at the location where the drag gesture terminated (e.g., by user lift-off of the contact corresponding to the drag gesture or by timing-out of the drag gesture by maintaining a relatively stable position for a pre-defined period of time). For example, in <figref idref="f0489">Figure 39J</figref>, electronic snowman sticker 3906 is placed at position 3906-b in transcript 3700, where it was displayed when the device detected termination (e.g., lift-off) of the drag gesture including contact 3916.

1396In some embodiments, the conversation transcript includes display of one or more objects posted to the messaging session (e.g., message bubbles, icons for interactive applications, and/or multimedia content), the location is based on the second location is a nearest position in a plurality of positions that are defined by the positions of the one or more objects posted to the messaging session (6216). For example, device 100-1 detects termination of a drag gesture including contact 3924 at position 3924-b in conversation transcript, when electronic snowflake sticker 3908 is displayed at position 3908-c, in <figref idref="f0494">Figure 39O</figref>. In response, snowflake sticker 3908 is placed (e.g., displayed) at position 3908-d, corresponding to the nearest point on a message object (e.g., message region 3749), in <figref idref="f0495">Figure 39P</figref>.

1397In some embodiments, the plurality of positions include positions that are defined by the outside border of the one or more objects posted to the messaging session (e.g., every position defining the outlines of the one or more objects, a set number of positions on the outlines (e.g., horizontal and vertical mid-points on the top, bottom, right, and left borders of each object), regularly spaced positions along the outside border (e.g., every X pixels or spaced to provide Y positions on each object)).

1398In some embodiments, the plurality of positions include positions that are defined by the surface area of the one or more objects posted to the messaging session (e.g., every position within the border (inclusive or exclusive) of an object, a set number of positions within each object (e.g., quadrant midpoints within each object), regularly spaced positions within each object (e.g., every (X, Y) pixels or spaced to provide Z positions within each object).

1399In some embodiments, the plurality of positions include one or more positions that are defined by a relationship between two adjacent objects (e.g., positions defined by the mid-point between two objects).

1400In some embodiments, in response to detecting termination of the first drag gesture, in accordance with a determination that the second location is within the conversation transcript, the device (6218) transmits information that represents the electronic sticker to one or more {e.g., at least a second} electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display a corresponding representation of the electronic sticker in a corresponding location within a corresponding conversation transcript

1401In some embodiments, where messages sent from the user of the electronic device and messages received from other users are displayed on opposite sides of a conversation transcript, the corresponding location is a position that is a mirror image of the position at which the stick is displayed on the sending user's electronic device (e.g., a mirror image of the position or a mirror image of the position and the sticker).

1402In some embodiments, the device (6220) detects a user input while the focus selector is at a third position that corresponds to a second electronic sticker in the plurality of electronic stickers (e.g., while a contact on a touch-sensitive display is at the second electronic sticker, or while a cursor or other pointer is at the second electronic sticker). For example, an input including one of contact 3912, in <figref idref="f0483">Figure 39D</figref> and contact 3932, in <figref idref="f0505">Figure 39Z</figref>,

1403In response to detecting the user input while the focus selector is at the third position, in accordance with a determination that the user input satisfies one or more sticker-selection-criteria (e.g., which are distinct from sticker posting criteria), the device displays the second electronic sticker in the message-input area (e.g., snowflake sticker 3908 is displayed in message-input area 3502 in <figref idref="f0485">Figure 39F</figref>.

1404In some embodiments, the sticker selection criteria include a criterion that is configured to be met when a characteristic intensity of a contact in the input remains below a first intensity threshold.

1405In some embodiments, the sticker selection criteria include a criterion that is met when a characteristic intensity of a contact in the input satisfies a first intensity threshold (e.g., the sticker is displayed in the message-input area, but may be pushed-through to the transcript by pressing harder)

1406In some embodiments, the sticker can then be posted to the messaging session by a second user input corresponding to a request to post the content within the message-input area, such as a tap gesture at a location that corresponds to a send icon on the display. For example, snowflake sticker 3908 is displayed in conversation transcript 3700, in <figref idref="f0486">Figure 39G</figref>, in response to a tap gesture including contact 3914 on send affordance 3520, in <figref idref="f0485">Figure 39F</figref>.

1407In response to detecting the user input while the focus selector is at the third position, in accordance with a determination that the user input satisfies one or more sticker-posting-criteria, displaying the sticker in the conversation transcript at a location that corresponds to a next message insertion point. For example, snowman sticker 3906 is directly posted to the messaging session (e.g., displayed in transcript 3700), in <figref idref="f0506">Figure 39AA</figref> in response to detecting deep press gesture including contact 3932.

1408In some embodiments, the sticker posting criteria include a criterion that is met when a characteristic intensity of a contact in the input goes above a second intensity threshold.

1409In some embodiments, posting the sticker to the messaging session at the position where the next messaging bubble would be located, e.g., at position 3908-b in <figref idref="f0486">Figure 39G</figref> or position 3906-c in <figref idref="f0506">Figure 39AA</figref>.

1410In some embodiments, the one or more sticker-posting-criteria require that a characteristic intensity of the first contact on the touch-sensitive surface meet a respective intensity threshold in order for the transcript-area-display criteria to be met are met when the characteristic intensity of the first contact is between the second intensity threshold and a third intensity threshold; and the one or more sticker-selection-criteria do not require that the characteristic intensity of the contact on the touch-sensitive surface meet the respective intensity threshold in order for the selection criteria to be met..

1411In some embodiments, the device detects (6222) a user input while the focus selector is at a fourth position that corresponds to a third electronic sticker in the plurality of electronic stickers (e.g., while a contact on a touch-sensitive display is at the third electronic sticker, or while a cursor or other pointer is at the third electronic sticker) wherein the third electronic sticker is associated with a sticker animation. For example, in <figref idref="f0496 f0503">Figures 39Q-39X</figref>, snowman sticker 3906 is associated with an animation including movement of the snowman's broom up and down, cycling through animation states 3930-a, 3930-b, and 3930-c. Device 100-1 detects an input including contact 3928 on snowman sticker 3906 in sticker pack 3904.

1412In some embodiments, the sticker animation is displayed in a loop when the sticker is posted to the messaging session. In some embodiments, the sticker animation is displayed a pre-defined number of times after being posted to the messaging session. In some embodiments, the sticker animation is displayed upon activation by a user within a corresponding conversation transcript. In some embodiments, the sticker animation is automatically displayed in the sticker pack.

1413In response to detecting the user input while the focus selector is at the fourth position, in accordance with a determination that the user input satisfies one or more animation preview criteria (e.g., deep-press criteria) the device previews the sticker animation associated with the third electronic sticker (e.g., a cat sticker cries when a user presses on the cat sticker in a sticker pack). For example, device 100-1 displays a preview of the animation for snowman sticker displayed in sticker pack 3904, in <figref idref="f0501 f0503">Figures 39-V-39X</figref>.

1414In some embodiments, the animation preview criteria include a criterion that is met when a characteristic intensity of a contact in the input satisfies an intensity threshold. In some embodiments, a press and hold gesture satisfies animation preview criteria. In some embodiments, a deep press gesture satisfies animation preview criteria. In some embodiments, a light press does not satisfy animation preview. In some embodiments, a light press gesture causes the electronic sticker to be displayed in the message-input area}, previewing the sticker animation associated with the third electronic sticker (e.g., a cat sticker cries when a user presses on the cat sticker in a sticker pack).

1415In some embodiments, prior to displaying the plurality of electronic stickers, the device (6224) displays the messaging user interface including the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between the user of the electronic device and the at least one other user (e.g., of another electronic device) and an application affordance (e.g., user interface 3500 in <figref idref="f0480">Figure 39A</figref>).

1416While displaying the messaging user interface, the device detects an input that activates the application affordance. For example, an input including contact 3902 on application affordance 3508, in <figref idref="f0481">Figure 39B</figref> (e.g., detecting a tap gesture at a location that corresponds to the application affordance).

1417In response to detecting the input that activates the application affordance, the device maintains display of at least a portion of the conversation transcript in a first area of the display (e.g., <figref idref="f0482">Figure 39C</figref> includes a portion of conversation transcript 3700 displayed in <figref idref="f0482">Figure 39C</figref>. The device displays the plurality of electronic stickers in a second area of the display (e.g., in sticker pack 3904, in <figref idref="f0482">Figure 39C</figref>).

1418In some embodiments, where the messaging user interface includes display of an electronic keyboard prior to activating the application affordance, the display of the plurality of electronic stickers replaces display of the keyboard (e.g., display of sticker pack 3904 would replace display of digital keyboard 3501).

1419In some embodiments, where the messaging user interface includes a full-screen display of the conversation transcript prior to activating the application affordance, the display of the plurality of electronic stickers replaces a portion of the display of the message transcript. For example, in <figref idref="f0481">Figure 39B</figref>, conversation transcript 3700 is displayed in full-screen mode. In response to activation of sticker pack 3892 by an input including contact 3902 in <figref idref="f0481">Figure 39B</figref>, display of conversation transcript 3700 is reduced to accommodate display of the sticker pack in <figref idref="f0482">Figure 39C</figref>.

1420In some embodiments, prior to displaying the plurality of electronic stickers: the device (6226) displays the messaging user interface including the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between the user of the electronic device and the at least one other user (e.g., of an electronic device) and an application affordance. For example, messaging user interface 3500 in <figref idref="f0507">Figure 39AB</figref>.

1421While displaying the messaging user interface, the device detects an input that activates the application affordance. For example, in <figref idref="f0507">Figure 39AB</figref>, an input including contact 3934 activates application affordance 3508.

1422In response to detecting the input that activates the application affordance, the device maintains display of at least a portion of the conversation transcript in a first area of the display (e.g., device 100-1 maintains display of conversation transcript 3700 in <figref idref="f0508">Figure 39AC</figref>), and the device displays a first interactive application icon (e.g., an icon for a first interactive application), which is one of a plurality of interactive application icons, in a second area of the display (e.g., in a scrollable interactive application panel). For example, interactive reservations application launch icon 3708 displayed in application slide tray 3892, in <figref idref="f0508">Figure 39AC</figref>.

1423In some embodiments, where the messaging user interface includes display of an electronic keyboard prior to activating the application affordance, the display of the scrollable interactive application panel replaces display of the keyboard (e.g., application slide tray 3892 may replace display of digital keyboard 3501.

1424In some embodiments, where the messaging user interface includes a full-screen display of the conversation transcript prior to activating the application affordance, the display of the scrollable interactive application panel replaces a portion of the display of the message transcript. For example, in <figref idref="f0508">Figure 39AC</figref>, application slide tray 3892 replaces a portion of transcript 3700, displayed in full-screen mode in <figref idref="f0507">Figure 39AB</figref>.

1425While displaying the first interactive application icon in the second area of the display, detecting a first swipe gesture that includes horizontal movement of a first contact at a location that corresponds to the second area of the display. For example, device 100-1 detects a swipe gesture including movement 3938 of contact 3936 from position 3936-a, in <figref idref="f0509">Figure 39AD</figref>, to position 3936-b, in <figref idref="f0510">Figure 39AE</figref>.

1426In accordance with a determination that the first swipe gesture satisfies one or more interactive application icon switching criteria, the device replaces display of the first interactive application icon with display of the plurality of electronic stickers in the second area of the display. For example, sticker pack 3904, in <figref idref="f0511">Figure 39AF</figref>, replaces display of interactive reservations application launch icon 3708, in <figref idref="f0509">Figure 39AD</figref>, in accordance to movement 3938 of contact 3936.

1427In some embodiments, the interactive application icon switching criteria includes a criterion that the magnitude of a horizontal movement of the first swipe gesture satisfies a predetermined movement threshold. In some embodiments, the predetermined movement threshold varies with the speed of the movement of the contact.

1428In some embodiments, prior to displaying the plurality of electronic stickers, the device (6228) displays the messaging user interface including the conversation transcript (e.g., displayed in a first area of the display) of the messaging session between the user of the electronic device and the at least one other user (e.g., of another electronic device) and an application affordance (e.g., messaging user interface 3500 in <figref idref="f0526">Figure 39AU</figref>.

1429While displaying the messaging user interface, the device detects an input that activates the application affordance (e.g., detecting a tap gesture at a location that corresponds to the application affordance). For example, in <figref idref="f0526">Figure 39AU</figref>, an input including contact 3952 activates application affordance 3508.

1430In response to detecting the input that activates the application affordance, the device maintains display of at least a portion of the conversation transcript in a first area of the display (e.g., device 100-1 maintains display of conversation transcript 3700 in <figref idref="f0527">Figure 39AV</figref>) and displays in a second area of the display that includes a plurality of application launch icons (e.g., including launch icons for one or more interactive applications; e.g., application selection tray 3654 in <figref idref="f0527">Figure 39AV</figref>), an application launch icon for a sticker pack (e.g., sticker pack launch icon 3609 in application selection tray 3654 in <figref idref="f0527">Figure 39AV</figref>.

1431In some embodiments, where the messaging user interface includes display of an electronic keyboard prior to detecting activation of the application affordance, the display of the plurality of application launch icons replaces display of the keyboard. For example, display of application selection tray 3654, in <figref idref="f0300">Figure 36Y</figref>, replaces digital keyboard 3501, in <figref idref="f0299">Figure 36X</figref>.

1432In some embodiments, where the messaging user interface includes a full-screen display of the conversation transcript prior to detecting activation of the application affordance, the display of the plurality of application launch icons replaces a portion of the display of the message transcript. For example, in <figref idref="f0527">Figure 39AV</figref>, application selection tray 3654 replaces a portion of transcript 3700, displayed in full-screen mode, in <figref idref="f0526">Figure 39AU</figref>.

1433While displaying the plurality of application launch icons, the device detects an input that activates the application launch icon for the sticker pack. For example, device 100-1 detects an in input including contact 3954 over sticker pack launch icon 3609, in <figref idref="f0527">Figure 39AV</figref>.

1434In response to a detecting the input that activates the application launch icon for the sticker pack (e.g., detecting a tap gesture at a location that corresponds to the launch icon for the sticker pack), the device replaces display of the plurality of application launch icons with display of the plurality of electronic stickers in the second area of the display. For example, in response to detecting an input including contact 3954, in <figref idref="f0527">Figure 39AV</figref>, device 100-1 replaces display of application selection tray 3954, in <figref idref="f0527">Figure 39AV</figref>, with display of sticker pack 3904, in <figref idref="f0528">Figure 39AW</figref>.

In response to detecting the user input while the focus selector is at the fourth position, in accordance with a determination that the user input satisfies one or more animation preview criteria, preview (e.g., with previewing unit 6318) the sticker animation associated with the third electronic sticker.

1443In some embodiments, the processing unit 6306 is further configured to: prior to displaying the plurality of electronic stickers: enable display of (e.g., with enabling unit 6308) the messaging user interface including the conversation transcript of the messaging session between the user of the electronic device and the at least one other user and an application affordance. While displaying the messaging user interface, the processing unit 6306 is configured to detect (e.g., with detecting unit 6310) an input that activates the application affordance. In response to detecting the input that activates the application affordance, the processing unit 6306 is configured to: maintain display of (e.g., with maintaining unit 6320) at least a portion of the conversation transcript in a first area of the display, and enable display of (e.g., with enabling unit 6308) the plurality of electronic stickers in a second area of the display.

1444In some embodiments, the processing unit 6306 is further configured to: prior to displaying the plurality of electronic stickers: enable display of (e.g., with enabling unit 6308) the messaging user interface including the conversation transcript of the messaging session between the user of the electronic device and the at least one other user and an application affordance. While displaying the messaging user interface, the processing unit 6306 is configured to detect (e.g., with detecting unit 6310) an input that activates the application affordance. In response to detecting the input that activates the application affordance, the processing unit 6306 is configured to: maintain display of (e.g., with maintaining unit 6320) at least a portion of the conversation transcript in a first area of the display, and enable display of (e.g., with enabling unit 6308) a first interactive application icon, which is one of a plurality of interactive application icons, in a second area of the display. While displaying the first interactive application icon in the second area of the display, the processing unit 6306 is configured to detect (e.g., with detecting unit 6310) a first swipe gesture that includes horizontal movement of a first contact at a location that corresponds to the second area of the display. In accordance with a determination that the first swipe gesture satisfies one or more interactive application icon switching criteria, the processing unit 6306 is configured to replace display of (e.g., with replacing unit 6322) the first interactive application icon with display of the plurality of electronic stickers in the second area of the display.

1445In some embodiments, the processing unit 6306 is further configured to: prior to displaying the plurality of electronic stickers: enable display of (e.g., with enabling unit 6308) the messaging user interface including the conversation transcript of the messaging session between the user of the electronic device and the at least one other user and an application affordance. While displaying the messaging user interface, the processing unit 6306 is configured to detect (e.g., with detecting unit 6310) an input that activates the application affordance. In response to detecting the input that activates the application affordance, the processing unit 6306 is configured to: maintain display of (e.g., with maintaining unit 6320) at least a portion of the conversation transcript in a first area of the display, and enable display of (e.g., with enabling unit 6308), in a second area of the display that includes a plurality of application launch icons, an application launch icon for a sticker pack. While displaying the plurality of application launch icons, the processing unit 6306 is configured to detect (e.g., with detecting unit 6310) an input that activates the application launch icon for the sticker pack.

1446In some embodiments, the plurality of electronic stickers is a plurality of objects contained within a digital image, wherein: the first electronic sticker corresponds to an object displayed at the first location at the start of the first drag gesture; and moving the first electronic sticker includes displaying an animation of peeling the first electronic sticker from the digital image.

1447The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to <figref idref="f0001">Figures 1A</figref> and <figref idref="f0004">3</figref>) or application specific chips.

1448The operations described above with reference to <figref idref="f0601 f0603">Figures 62A-62C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0604">Figure 63</figref>. For example, detection operation 6204 and move operation 6206 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1449<figref idref="f0605 f0607">Figures 64A-64C</figref> are flow diagrams illustrating a method 6400 of modifying display of electronic stickers in a messaging application in accordance with some embodiments. The method 6400 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 6400 are, optionally, combined and/or the order of some operations is, optionally, changed.

1450As described below, the method 6400 provides an intuitive way to modify display of electronic stickers in a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when modifying display of electronic stickers in a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to modify display of electronic stickers in a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1451The device displays (6402) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), a plurality of electronic stickers (e.g., a sticker pack displayed in a second area of the display), and a message-input area. For example in <figref idref="f0511">Figure 39AF</figref>, device 100-1 displays messaging user interface 3500, including conversation transcript 3700, electronic sticker pack 3892, including electronic stickers 3906, 3908, and 3910, and message-input area 3502.

1452While displaying the messaging user interface (e.g., user interface 3500), the device detects (6404) a first user input (e.g., by a first contact on a touch-sensitive surface, such as a drag gesture or a tap gesture) while a focus selector is at a first location in the messaging user interface that corresponds to a first electronic sticker in the plurality of electronic stickers (e.g., detect a drag gesture by a contact on a touch-sensitive display that starts at the first electronic sticker and moves in a first direction, or detect a drag gesture by a contact on a touch-sensitive surface that starts while a cursor or other pointer is at the first electronic sticker on the display and moves the pointer in a first direction on the display). In some embodiments, the first electronic sticker is initially not within the conversation transcript (e.g., the first electronic sticker is in a sticker pack displayed in a second area of the display).

1453For example, device 100-1 detects an input including: a drag gesture, including movement 3942 of contact 3940 from position 3940-a, over electronic snowman sticker 3906 displayed in sticker pack 3904, in <figref idref="f0512">Figure 39AG</figref>, through position 3940-b, in <figref idref="f0513">Figure 39AH</figref>, to position 3940-c, in <figref idref="f0514">Figure 39AI</figref>; increases in a characteristic intensity of contact 3940 between <figref idref="f0512 f0513">Figures 39AG-39AH</figref> and <figref idref="f0513 f0514">39AH-39AI</figref>, respectively; a decrease in a characteristic intensity of contact 3940 between <figref idref="f0514">Figure 39AI</figref> and <figref idref="f0515">Figure 39AJ</figref>; and a rotation gesture, including rotation 3944 of contact 3940 from orientation (e.g., position) 3940-c, in <figref idref="f0516">Figure 39AK</figref>, to orientation (e.g., position) 3940-d, in <figref idref="f0517">Figure 39AL</figref>.

1454In response to detecting the first user input, the device (6406) places and displays the first electronic sticker in the conversation transcript. For example, device 100-1 displays electronic sticker 3906 at position (e.g., location and orientation) 3906-f, in <figref idref="f0518">Figure 39AM</figref>.

1455While the first electronic sticker is displayed in the conversation transcript, the device (6408): detects a second user input while a focus selector is at a second location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript (e.g., detect a drag gesture, a portion of a depinch gesture, or a rotate gesture by a contact on a touch-sensitive display that starts at the location of the first electronic sticker in the transcript, or detect a drag gesture, a portion of a depinch gesture, or a rotate gesture by a contact on a touch-sensitive surface that starts while a cursor or other pointer is at the location of the first electronic sticker in the transcript).

1456For example, device 100-1 detects an input including: movement 3948 of contact 3946, within conversation transcript 3700, from position 3946-a, in <figref idref="f0519">Figure 39AN</figref>, to position 3946-b, in <figref idref="f0520">Figure 39AO</figref>; an increase in a characteristic intensity of contact 3946 between <figref idref="f0520">Figure 39AO</figref> and <figref idref="f0521">Figure 39AP</figref>; and rotation 3950 of contact 3946 from orientation (e.g., position) 3946-b, in <figref idref="f0522">Figure 39AQ</figref>, to orientation (e.g., position) 3946-c, in <figref idref="f0497">Figure 39R</figref>.

1457In some embodiments, the first and second user inputs are first and second parts of a single continuous input, e.g., a drag gesture followed by a pinch or rotation gesture made with the same contact.

1458In response to detecting the second user input, the device (6408) changes the position, size, and/or rotation of the first electronic sticker in the conversation transcript. (e.g., while maintaining a constant display of the conversation transcript behind the first electronic sticker).

1459For example, device 100-1 moves electronic snowman sticker 3906 from position 3906-f, in <figref idref="f0519">Figure 39AN</figref>, to position 3906-g, in <figref idref="f0520">Figure 39AO</figref>. In another example, device 100-1 increases the size of electronic snowman sticker 3906, displayed in transcript 3700, between <figref idref="f0520">Figure 39AO</figref> and Figure AP. In another example, device 100-1 rotates electronic snowman sticker 3906 from orientation (e.g., position) 3906-g, in <figref idref="f0522">Figure 39AQ</figref>, to orientation (e.g., position) 3906-h, in <figref idref="f0523">Figure 39AR</figref>.

1460In some embodiments, the size of the first electronic sticker is reduced (6410) in response to detecting a pinch gesture that includes movement of a first contact towards a second contact, wherein the pinch gesture started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker (e.g., pinching while over the electronic sticker reduces the display size of the sticker without changing the display size of the conversation transcript).

1461In some embodiments, the size of the first electronic sticker is increased (6412) in response to detecting a depinch gesture that includes movement of a first contact away from a second contact, wherein the depinch gesture started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker (e.g., depinching while over the electronic sticker increases the display size of the sticker without changing the display size of the conversation transcript).

1462In some embodiments, the size of the first electronic sticker is increased (6414) in accordance with a (e.g., change in a) characteristic intensity of a contact made while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker. For example, the size of electronic snowman sticker 3906 is increased between <figref idref="f0512 f0513">Figures 39AG-39AH</figref>, <figref idref="f0513 f0514">39AH-39AI</figref>, and <figref idref="f0520 f0521">39AO-39AP</figref>, respectively.

1463In some embodiments, the size of the first electronic sticker is decreased in accordance with a (e.g., change in a) characteristic intensity of a contact made while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker. For example, the size of electronic snowman sticker 3906 is decreased between <figref idref="f0514">Figure 39AI</figref> and <figref idref="f0515">Figure 39AJ</figref>.

1464In some embodiments, the orientation of the first electronic sticker is changed (6416) in response to detecting a rotation gesture that started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker. For example, the orientation (e.g., position) of electronic snowman sticker 3906 is rotated from orientation 3906-e, in <figref idref="f0516">Figure 39AK</figref>, to orientation 3906-f, in <figref idref="f0517">Figure 39AL</figref>. In another example, the orientation (e.g., position) of electronic snowman sticker 3906 is rotated from orientation 3906-g, in <figref idref="f0522">Figure 39AQ</figref>, to orientation 3906-h, in <figref idref="f0523">Figure 39AR</figref>.

1465In some embodiments, the rotation gesture includes rotation of a single user contact. In some embodiments, the rotation gesture includes rotation of a first contact relative to a second contact.

1466In some embodiments, after detecting the first user input, the device transmits (6418) information that represents the first electronic sticker to one or more (e.g., second) electronic devices that correspond to the at least one other user included in the messaging session, wherein the one or more electronic devices display a corresponding representation of the first electronic sticker in a corresponding location (e.g., a corresponding location, size, and rotation) within a corresponding conversation transcript (e.g., corresponding to the messaging session).

1467In some embodiments, information that represents the first electronic sticker is sent in response to detecting the first user input (e.g., upon detection of lift-off of contact 3940 in <figref idref="f0518">Figure 39AM</figref>), and subsequent movement, resizing, and/or rotation of the sticker causes the device to send subsequent information that represents the first electronic sticker (e.g., the position, including location, size, and/or orientation) (e.g., upon detection of lift-off of contact 3946 in <figref idref="f0524">Figure 39AS</figref>).

1468In some embodiments, information that represents the first electronic sticker is not sent until the user has finally positioned, sized, and/or rotated the sticker within the conversation transcript (e.g., with the second user input). For example, information is sent upon detection of lift-off of contact 3946 in <figref idref="f0524">Figure 39AS</figref>, but not upon detection of lift-off of contact 3940 in <figref idref="f0518">Figure 39AM</figref>.

1469In some embodiments, once the user places, sizes, and/or rotates the electronic sticker, further modifications to the sticker in the transcript cannot be made (e.g., detection of a second input, including second contact 3946, in <figref idref="f0519">Figure 39AN</figref>, would not cause device 100-1 to move, resize, or rotate electronic snowman sticker 3906 within conversation transcript 3700).

1470In some embodiments, once the user places, sizes, and/or rotates the electronic sticker, further modifications to the sticker in the transcript can only be made within a predetermined time period (e.g., initiation of further modifications) beginning at termination of the first input, placing the sticker in the conversation transcript. For example, detection of a second input, including second contact 3946, in <figref idref="f0519">Figure 39AN</figref>, would only cause device 100-1 to move, resize, or rotate electronic snowman sticker 3906 within conversation transcript 3700 if the second input was first detected within the predefined time period.

1471In some embodiments, after transmitting the information that represents the first electronic sticker to the one or more electronic devices, the device (6420) detects a third user input while a focus selector is at a third location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript and, in response to detecting the third user input: changes the position of the first electronic sticker in the conversation transcript for a second time, and sends information to the one or more electronic devices that correspond to the at least one other user included in the messaging session that the position of the first electronic sticker was changed in the conversation transcript, wherein the one or more electronic devices make corresponding changes to the position of the first electronic sticker within the corresponding conversation transcript (e.g., to match or mirror the changes made in the first user's conversation transcript).

1472In some embodiments, only the user who posted the sticker to the messaging session can change the position, size, or rotation of the sticker. In some embodiments, any user included in the messaging session can change the position, size, and/or rotation of the sticker. In some embodiments, no user can change the position, size and/or rotation of the sticker once it has been posted to the messaging session.

1473In some embodiments, after transmitting the information that represents the first electronic sticker to the one or more electronic devices, the device (6422) detects a third user input while a focus selector is at a third location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript and, in response to detecting the third user input: changes the rotation (e.g., orientation) of the first electronic sticker in the conversation transcript for a second time, and sends information to the one or more electronic devices that correspond to the at least one other user included in the messaging session that the rotation (e.g., orientation) of the first electronic sticker was changed in the conversation transcript, wherein the one or more electronic devices make corresponding changes to the rotation (e.g., orientation) of the first electronic sticker within the corresponding conversation transcript (e.g., to match or mirror the changes made in the first user's conversation transcript).

1474In some embodiments, only the user who posted the sticker to the messaging session can change the position, size, or rotation of the sticker. In some embodiments, any user included in the messaging session can change the position, size, and/or rotation of the sticker. In some embodiments, no user can change the position, size and/or rotation of the sticker once it has been posted to the messaging session.

1475In some embodiments, after transmitting the information that represents the first electronic sticker to the one or more electronic devices, the device (6424) detects a third user input while a focus selector is at a third location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript and, in response to detecting the third user input: changes the size of the first electronic sticker in the conversation transcript for a second time, and sends information to the one or more electronic devices that correspond to the at least one other user included in the messaging session that the size of the first electronic sticker was changed in the conversation transcript, wherein the one or more electronic devices make corresponding changes to the size of the first electronic sticker within the corresponding conversation transcript (e.g., to match or mirror the changes made in the first user's conversation transcript).

1476In some embodiments, only the user who posted the sticker to the messaging session can change the position, size, or rotation of the sticker. In some embodiments, any user included in the messaging session can change the position, size, and/or rotation of the sticker. In some embodiments, no user can change the position, size and/or rotation of the sticker once it has been posted to the messaging session.

1477In some embodiments, after transmitting the information that represents the first electronic sticker to the one or more electronic devices, the device receives information from an electronic device that corresponds to another user included in the messaging session that the position, size, and/or orientation of a corresponding representation of the first electronic sticker was changed in a corresponding conversation transcript and, in response, changes the position, size, and/or orientation of the first electronic sticker in the conversation transcript. For example, device 100-1 receives information from device 100-2 at 9:56 AM and, in response, changes the position, size, and orientation of electronic snowman sticker 3906 from location 3906-h, in <figref idref="f0524">Figure 39AS</figref>, to location 3906-i, in <figref idref="f0525">Figure 39AT</figref>.

1478In some embodiments, in response to detecting the first user input, the device changes (6426) the position, of the first electronic sticker (e.g., the size, position, and orientation of the sticker can be changes while still displayed in the sticker pack and/or while being dragged into the conversation transcript). For example, movement of electronic snowman sticker 3906 from position 3906-a, in <figref idref="f0512">Figure 39AG</figref>, through position 3906-d, in <figref idref="f0513">Figure 39AH</figref>, to position 3906-e, in <figref idref="f0514">Figure 39AI</figref>.

1479In some embodiments, in response to detecting the first user input, the device changes (6428) the size of the first electronic sticker (e.g., the size, position, and orientation of the sticker can be changes while still displayed in the sticker pack and/or while being dragged into the conversation transcript). For example, the size of electronic snowman sticker 3906 is increased between <figref idref="f0512 f0513">Figures 39AG-39AH</figref> and <figref idref="f0513 f0514">39AH-39AI</figref>, respectively. In another example, the size of electronic snowman sticker 3906 is decreased between <figref idref="f0514">Figure 39AI</figref> and <figref idref="f0515">Figure 39AJ</figref>.

1480In some embodiments, in response to detecting the first user input, the device changes (6430) the rotation of the first electronic sticker (e.g., the size, position, and orientation of the sticker can be changes while still displayed in the sticker pack and/or while being dragged into the conversation transcript). For example, electronic snowman sticker 3906 is rotated from orientation (e.g., position) 3906-e, in <figref idref="f0516">Figure 39AK</figref>, to orientation (e.g., position) 3906-f, in <figref idref="f0517">Figure 39AL</figref>.

1481It should be understood that the particular order in which the operations in <figref idref="f0605 f0607">Figures 64A-64C</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6600, 6800, and 7000) are also applicable in an analogous manner to method 6400 described above with respect to <figref idref="f0605 f0607">Figures 64A-64C</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described above with reference to method 6400 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6600, 6800, and 7000). For brevity, these details are not repeated here.

1482In accordance with some embodiments, <figref idref="f0608">Figure 65</figref> shows a functional block diagram of an electronic device 6500 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0608">Figure 65</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1483As shown in <figref idref="f0608">Figure 65</figref>, an electronic device 6500 includes a display unit 6502 configured to display user interfaces; a touch-sensitive surface unit 6504 configured to detect contacts; and a processing unit 6506 coupled with the display unit 6502 and the touch-sensitive surface unit 6504.

1487In some embodiments, the processing unit 6506 is further configured to: after transmitting the information that represents the first electronic sticker to the one or more electronic devices: detect (e.g., with detecting unit 6510) a third user input while a focus selector is at a third location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript; and, in response to detecting the third user input: change (e.g., with changing unit 6514) the rotation of the first electronic sticker in the conversation transcript for a second time; and send (e.g., with sending unit 6518) information to the one or more electronic devices that correspond to the at least one other user included in the messaging session that the rotation of the first electronic sticker was changed in the conversation transcript, wherein the one or more electronic devices make corresponding changes to the rotation of the first electronic sticker within the corresponding conversation transcript.

1488In some embodiments, the processing unit 6506 is further configured to: after transmitting information that represents the first electronic sticker to the one or more electronic devices: detect (e.g., with detecting unit 6510)a third user input while a focus selector is at a third location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript; and, in response to detecting the third user input: change (e.g., with changing unit 6514) the size of the first electronic sticker in the conversation transcript for a second time; and send (e.g., with sending unit 6518) information to the one or more electronic devices that correspond to the at least one other user included in the messaging session that the size of the first electronic sticker was changed in the conversation transcript, wherein the one or more electronic devices make corresponding changes to the size of the first electronic sticker within the corresponding conversation transcript.

1489In some embodiments, the processing unit 6506 is further configured to: in response to detecting the first user input, change (e.g., with changing unit 6514) the position, of the first electronic sticker.

1490In some embodiments, the processing unit 6506 is further configured to: in response to detecting the first user input, change (e.g., with changing unit 6514) the size of the first electronic sticker.

1491In some embodiments, the processing unit 6506 is further configured to: in response to detecting the first user input, change (e.g., with changing unit 6514) the rotation of the first electronic sticker.

1492In some embodiments, the size of the first electronic sticker is reduced in response to detecting a pinch gesture that includes movement of a first contact towards a second contact, wherein the pinch gesture started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker.

1493In some embodiments, the size of the first electronic sticker is increased in response to detecting a depinch gesture that includes movement of a first contact away from a second contact, wherein the depinch gesture started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker.

1494In some embodiments, the size of the first electronic sticker is increased in accordance with a characteristic intensity of a contact made while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker.

1495In some embodiments, the orientation of the first electronic sticker is changed in response to detecting a rotation gesture that started while a focus selector was at a location in the messaging user interface that corresponds to the first electronic sticker.

1496The operations described above with reference to <figref idref="f0605 f0607">Figures 64A-64C</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0608">Figure 65</figref>. For example, detection operations 6404 and 6408 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Making payments

1497<figref idref="f0609">Figure 66</figref> is a flow diagram illustrating a method 6600 of making payments from a messaging application in accordance with some embodiments. The method 6600 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 6600 are, optionally, combined and/or the order of some operations is, optionally, changed.

1498As described below, the method 6600 provides an intuitive way to make payments from a messaging application. The method reduces the number, extent, and/or nature of the inputs from a user when making payments from a messaging application, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to make payments from a messaging application faster and more efficiently conserves power and increases the time between battery charges.

1499The device displays (6602) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device) and a message-input area, wherein each of the other users included in the messaging session has a corresponding avatar (e.g., displayed in a second area of the display). For example, messaging user interface 3500, in <figref idref="f0534">Figure 40F</figref>, includes conversation transcript 3503, message-input area 3502. Conversation transcript 3503 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100-1 and other users included in the messaging session. Each of the other users included in the messaging transcript are represented by an avatar (e.g., avatar 4008 for "Mary Todd") displayed in stack of avatars 4002, in <figref idref="f0534">Figure 40F</figref>.

1500While displaying the messaging user interface, the device detects (6604) a first user input (e.g., a tap, light press, or deep press gesture by a contact on a touch-sensitive surface) while a focus selector is at a first location in the messaging user interface that corresponds to an avatar of a first other user included in the messaging session, (e.g., detect a gesture by a contact on a touch-sensitive display at the location of the avatar of the first other user, or detect a gesture by a contact on a touch-sensitive surface while a cursor or other pointer is at the location of the avatar of the first other user). For example, device 100-1 detects an input including contact 4010, on Mary Todd's avatar 4010, in <figref idref="f0535">Figure 40G</figref>.

1501In response to detecting the first user input, the device displays (6006) a menu that contains activatable menu items associated with the first other user overlaid on the messaging user interface, the displayed menu including an activatable menu item for initiating a payment action with the first other user (e.g., a menu item for paying, or requesting payment from, the first other user). For example, in response to detecting an input including an increase in a characteristic intensity of contact 4010, meeting a predefined intensity threshold, the device displays action menu 3882 that includes activatable action 3884-6 for making a payment to another user (e.g., Mary Todd) included in the messaging session, in <figref idref="f0536">Figure 40H</figref>.

1502While displaying the menu that contains activatable menu items associated with the first other user (e.g., action menu 3882 in <figref idref="f0538">Figure 40J</figref>), the device detects (6008) a second user input (e.g., by a contact on a touch-sensitive surface, such as an input including contact 4012, in <figref idref="f0538">Figure 40J</figref>) while a focus selector is at a second location in the messaging user interface that corresponds to the activatable menu item for initiating a payment action with the first other user (e.g., activatable menu action 3884-6 for a payment, in <figref idref="f0538">Figure 40J</figref>). For example, the device detects a gesture by a contact on a touch-sensitive display at the location of the activatable menu item for initiating a payment action with the first other user, or detects a gesture by a contact on a touch-sensitive surface while a cursor or other pointer is at the location of the activatable menu item for initiating a payment action with the first other user.

1503In response to detecting the second user input, the device displays (6610) a user interface configured to initiate sending of a payment to, and/or requesting a payment from, the first other user. For example, in response to detecting an input including contact 4012 on activatable payment action 3884-6, in <figref idref="f0538">Figure 40J</figref>, device 100-1 displays payment user interface 4014, in <figref idref="f0539">Figure 40K</figref>.

1504It should be understood that the particular order in which the operations in <figref idref="f0609">Figure 66</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6800, and 7000) are also applicable in an analogous manner to method 6600 described above with respect to <figref idref="f0609">Figure 66</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described above with reference to method 6600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6800, and 7000). For brevity, these details are not repeated here.

1505In accordance with some embodiments, <figref idref="f0610">Figure 67</figref> shows a functional block diagram of an electronic device 6700 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0610">Figure 67</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1506As shown in <figref idref="f0610">Figure 67</figref>, an electronic device 6700 includes a display unit 6702 configured to display user interfaces; a touch-sensitive surface unit 6704 configured to detect contacts; and a processing unit 6706 coupled with the display unit 6702 and the touch-sensitive surface unit 6704. The processing unit 6706 includes an enabling unit 6708 and a detecting unit 6710.

1507The processing unit 6706 is configured to enable display of (e.g., with enabling unit 6708) a messaging user interface of a messaging application on the display unit 6702, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user and a message-input area, wherein each of the other users included in the messaging session has a corresponding avatar. While displaying the messaging user interface, the processing unit 6706 is configured to detect (e.g., with detecting unit 6710) a first user input while a focus selector is at a first location in the messaging user interface that corresponds to an avatar of a first other user included in the messaging session. In response to detecting the first user input, enable display of (e.g., with enabling unit 6708) a menu that contains activatable menu items associated with the first other user overlaid on the messaging user interface, the displayed menu including an activatable menu item for initiating a payment action with the first other user. While displaying the menu that contains activatable menu items associated with the first other user, detect (e.g., with detecting unit 6710) a second user input while a focus selector is at a second location in the messaging user interface that corresponds to the activatable menu item for initiating a payment action with the first other user. In response to detecting the second user input, enable display of (e.g., with enabling unit 6708) a user interface configured to initiate sending of a payment to, and/or requesting a payment from, the first other user.

1508The operations described above with reference to <figref idref="f0609">Figure 66</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0610">Figure 67</figref>. For example, detection operations 6604 and 6608 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Interacting with avatars in a group messaging session

1509<figref idref="f0611 f0612">Figures 68A-68B</figref> are flow diagrams illustrating a method 6800 of interacting with a single user included in a group messaging session in accordance with some embodiments. The method 6800 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 6800 are, optionally, combined and/or the order of some operations is, optionally, changed.

1510As described below, the method 6800 provides an intuitive way to interact with a single user included in a group messaging session. The method reduces the number, extent, and/or nature of the inputs from a user when interacting with a single user included in a group messaging session, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to interact with a single user included in a group messaging session faster and more efficiently conserves power and increases the time between battery charges.

1511The device displays (6802) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and a plurality of other users (e.g., of respective other electronic devices), a message-input area, and a plurality of avatars, each respective avatar in the plurality of avatars corresponding to a respective other user in the plurality of other users included in the messaging session, wherein the plurality of avatars are displayed as a stack of (e.g., overlapping) avatars, with a first avatar in the plurality of avatars displayed on the top of the stack of avatars. For example, messaging user interface 3500, in <figref idref="f0547">Figure 40S</figref>, includes conversation transcript 3503 and message-input area 3502. Conversation transcript 3503 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100-1 and other users included in the messaging session. Each of the other users included in the messaging transcript are represented by an avatar (e.g., avatar 3510 for "Abe") displayed on top of stack of avatars 4002, in <figref idref="f0547">Figure 40S</figref>.

1512While displaying the messaging user interface, the device detects an input by a first contact on the touch-sensitive surface while a focus selector is at a first location in the messaging user interface that corresponds to the first avatar (e.g., detect a gesture by a contact on a touch-sensitive display at the location of the first avatar, or detect a gesture by a contact on a touch-sensitive surface while a cursor or other pointer is at the location of the first avatar). For example, device 100-1 detects an input including contact 4030 on Abe's avatar (e.g., displayed on top of stack of avatars 4002), in <figref idref="f0547">Figure 40S</figref>. In another example, device 100-1 detects an input including contact 4038 on Mary Todd's avatar 4008, in <figref idref="f0549">Figure 40U</figref>.

1513in response to detecting the input by the first contact, in accordance with a determination that the input meets menu-activation-criteria, wherein the menu-activation-criteria require that a characteristic intensity of the contact on the touch-sensitive surface meet a respective intensity threshold in order for the menu-activation criteria to be met, the device displays (6806) a menu that contains activatable menu items associated with the first avatar overlaid on the messaging user interface. For example, in response to detecting an increase in a characteristic intensity of contact 4038 on Mary Todd's avatar 4008, meeting a predetermined intensity threshold (e.g., IT_L or IT_D), between <figref idref="f0549">Figures 40U</figref> and <figref idref="f0550">40V</figref>, device 100-1 displays action menu 3882, including actions 3884 for directly interacting with Mary Todd (e.g., interacting only with Mary Todd), in <figref idref="f0550">Figure 40V</figref>.

1514in response to detecting the input by the first contact, in accordance with a determination that the input meets avatar-spreading-criteria, wherein the avatar-spreading-criteria do not require that a characteristic intensity of the contact on the touchscreen meet the respective intensity threshold in order for the selection criteria to be met, the device displays (6906) the plurality of avatars in an array (e.g., a substantially or completely non-overlapping array). For example, in response to detecting an input including contact 4030 on Abe's avatar 3510, in <figref idref="f0547">Figure 40S</figref>, where a characteristic intensity of contact 4030 does not meet a predetermined intensity threshold (e.g., IT_L or IT_D), device 100-1 displays an array of avatars in avatar stack 4002-e.g., Abe's avatar 3510, Mary Todd's avatar 4008, Chuck's avatar 4032, Issac's avatar 4034, and Edwin's avatar 4036-in <figref idref="f0548">Figure 40T</figref>.

1515In some embodiments, in accordance with a determination that a characteristic (e.g., a maximum) intensity of the first contact met a predefined intensity threshold (e.g., was between a first intensity threshold and a second intensity threshold), the device replaces display of the first avatar on top of the stack of avatars with display of a second avatar in the plurality of avatars on top of the stack of avatars. For example, in response to detecting an increase in a characteristic intensity of contact 4006 on Abe's avatar 3510, meeting a predetermined intensity threshold (e.g., IT_L or IT_D), between <figref idref="f0532">Figures 40D</figref> and <figref idref="f0533">40E</figref>, device 100-1 cycles (e.g., switches or shuffles) stack of avatars 4002 to display Mary Todd's avatar 4008 on top of stack of avatars 4002 in <figref idref="f0533 f0534">Figures 40E-40F</figref> (e.g., Mary Todd's avatar 4008 replaces Abe's avatar 3510 on top of stack of avatars 4002).

1516In some embodiments, in accordance with a determination that a characteristic (e.g., a maximum) intensity of the first contact did not meet a predetermined intensity threshold (e.g., was between the second intensity threshold and a third intensity threshold), the device displays a menu that contains activatable menu items associated with the first avatar overlaid on the messaging user interface. For example, in response to detecting an input including contact 4004 on Abe's avatar 3510, in <figref idref="f0530">Figure 40B</figref>, where a characteristic intensity of contact 4004 does not meet a predetermined intensity threshold (e.g., IT_L or IT_D), device 100-1 displays action menu 3882, including actions 3884 for directly interacting with Abe (e.g., interacting only with Abe), in <figref idref="f0531">Figure 40C</figref>.

1517In some embodiments, the second intensity threshold is above the first intensity threshold and the third intensity threshold is above the second intensity threshold (e.g., tap to cycle through the avatars and light press or deep press to call up a quick action menu for the avatar at the top of the stack).

1518In some embodiments, the second intensity threshold is below the first intensity threshold and the third intensity threshold is below the second intensity threshold (e.g., deep press or light press to cycle through the avatars and tap to call up the quick action menu for the avatar at the top of the stack).

1519In some embodiments, the avatar-spreading-criteria are met (6810) upon detection of a tap gesture on the touch-sensitive surface. For example, avatars 3510, 4008, 4032, 4034, and 4036, in avatar stack 4002, displayed in <figref idref="f0547">Figure 40S</figref>, are displayed as a spread array (e.g., a substantially or completely non-overlapping array), in <figref idref="f0548">Figure 40T</figref>, in response to detecting a tap gesture including contact 4030 on Abe's avatar 3510, in <figref idref="f0547">Figure 40S</figref>.

1520In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6812) a menu item that when activated initiates a canvas for sharing digital drawings with the other user (e.g., digital touch action 3884-5 in <figref idref="f0550">Figure 40V</figref>).

1521In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6814) a menu item that when activated initiates messaging with only the first other user (e.g., message action 3884-3 in <figref idref="f0550">Figure 40V</figref>).

1522For example, in some embodiments, selecting a messaging menu item (e.g., activatable action 3884-3) causes the electronic device to display a private messaging user interface between the user of the electronic device and the first other user. For example, in response to detecting an input including contact 3886 on activatable message action 3884-3, in <figref idref="f0478">Figure 38AY</figref>, while messaging user interface 3500 is displaying conversation transcript 3503 corresponding to a messaging session between the user of device 100-1 (e.g., "Andrew") and a plurality of other users, each represented by an avatar in the stack of avatars 4002, in <figref idref="f0478">Figure 38AY</figref>, device 100-1 replaces display of conversation transcript 3503, in <figref idref="f0478">Figure 38AY</figref>, with conversation transcript 3700, corresponding to a messaging session between only Abe and Andrew, in <figref idref="f0479">Figure 38AZ</figref>.

1523In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6816) a menu item that when activated initiates an email with the first other user (e.g., mail action 3884-4 in <figref idref="f0550">Figure 40V</figref>).

1524In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6818) a menu item that when activated initiates a call with the first other user (e.g., call action 3884-1 in <figref idref="f0550">Figure 40V</figref>).

1525In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6820) a menu item that when activated initiates a video conference with the first other user (e.g., video call action 3884-2 in <figref idref="f0550">Figure 40V</figref>).

1526In some embodiments, the menu that contains activatable menu items associated with the first avatar (e.g., action menu 3882 in <figref idref="f0550">Figure 40V</figref>) includes (6822) a menu item that when activated initiates a payment action with the first other user (e.g., payment action 3884-6 in <figref idref="f0550">Figure 40V</figref>).

1527It should be understood that the particular order in which the operations in <figref idref="f0611 f0612">Figures 68A-68B</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, and 7000) are also applicable in an analogous manner to method 6800 described above with respect to <figref idref="f0611 f0612">Figures 68A-68B</figref>. For example, the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described above with reference to method 6800 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile outputs, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, and 7000). For brevity, these details are not repeated here.

1528In accordance with some embodiments, <figref idref="f0613">Figure 69</figref> shows a functional block diagram of an electronic device 6900 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in <figref idref="f0613">Figure 69</figref> are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1529As shown in <figref idref="f0613">Figure 69</figref>, an electronic device 6900 includes a display unit 6902 configured to display user interfaces; a touch-sensitive surface unit 6904 configured to detect contacts; and a processing unit 6906 coupled with the display unit 6902 and the touch-sensitive surface unit 6904. The processing unit 6906 including: an enabling unit 6908 and detecting unit 6910.

1530The processing unit 6906 is configured to: enable display of (e.g., with enabling unit 6908) a messaging user interface of a messaging application on the display unit 6902, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and a plurality of other users, a message-input area, and a plurality of avatars, each respective avatar in the plurality of avatars corresponding to a respective other user in the plurality of other users included in the messaging session, wherein the plurality of avatars are displayed as a stack of avatars, with a first avatar in the plurality of avatars displayed on the top of the stack of avatars. While displaying the messaging user interface, the processing unit 6906 is configured to detect (e.g., with detecting unit 6910) an input by a first contact on the touch-sensitive surface unit 6904 while a focus selector is at a first location in the messaging user interface that corresponds to the first avatar. In response to detecting the input by the first contact: in accordance with a determination that the input meets menu-activation-criteria, wherein the menu-activation-criteria require that a characteristic intensity of the contact on the touch-sensitive surface unit 6904 meet a respective intensity threshold in order for the menu-activation criteria to be met, the processing unit 6906 is configured to enable display of (e.g., with enabling unit 6908) a menu that contains activatable menu items associated with the first avatar overlaid on the messaging user interface. In accordance with a determination that the input meets avatar-spreading-criteria, wherein the avatar-spreading-criteria do not require that a characteristic intensity of the contact on the touchscreen meet the respective intensity threshold in order for the selection criteria to be met, the processing unit 6906 is configured to enable display of (e.g., with enabling unit 6908) the plurality of avatars in an array.

1531In some embodiments, the avatar-spreading-criteria are met upon detection of a tap gesture on the touch-sensitive surface unit.

1532In some embodiments, the menu that contains activatable menu items associated with the first avatar includes a menu item that when activated initiates a canvas for sharing digital drawings with the other user.

1533In some embodiments, the menu that contains activatable menu items associated with the first avatar includes a menu item that when activated initiates messaging with only the first other user,

1534In some embodiments, the menu that contains activatable menu items associated with the first avatar includes a menu item that when activated initiates an email with the first other user,

1537In some embodiments, the menu that contains activatable menu items associated with the first avatar includes a menu item that when activated initiates a payment action with the first other user.

1538The operations described above with reference to <figref idref="f0611 f0612">Figures 68A-68B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0613">Figure 69</figref>. For example, detection operation 6804 and display operation 6806 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

Making suggestions in a messaging session

1539<figref idref="f0614 f0615">Figures 70A-70B</figref> are flow diagrams illustrating a method 7000 of displaying additional information in a messaging session in accordance with some embodiments. The method 7000 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 7000 are, optionally, combined and/or the order of some operations is, optionally, changed.

1540As described below, the method 7000 provides an intuitive way to display additional information in a messaging session. The method reduces the number, extent, and/or nature of the inputs from a user when displaying additional information in a messaging session, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to display additional information in a messaging session faster and more efficiently conserves power and increases the time between battery charges.

1541The device displays (7002) a messaging user interface of a messaging application on the display, the messaging user interface including a conversation transcript (e.g., displayed in a first area of the display) of a messaging session between a user of the electronic device and at least one other user (e.g., of another electronic device), and a message-input area. For example, messaging user interface 3500, in <figref idref="f0552">Figures 41A</figref> and <figref idref="f0554">41C</figref>, include conversation transcript 3503 and message-input area 3502.

1542While displaying the messaging user interface, the device receives (7004) a first message within the messaging session from an (e.g., second) electronic device that corresponds to another user included in the messaging session. For example device 100-1 receives message 4102 from Mary Todd, in <figref idref="f0552">Figure 41A</figref>.

1543In response to receiving the first message, the device (7006): displays the first message within a first message region (e.g., bubble) in the conversation transcript on the display (e.g., message 4102 is displayed within a message region in transcript 3503 in <figref idref="f0552">Figure 41A</figref>),

1544In response to receiving the first message, the device (7006): detects, in the first message, a word or phrase associated with additional content available on the Internet (e.g., information about a detected business/restaurant, music, movie, television show, current event, public figure, politician, celebrity, university, athlete, sporting event, or sports league/team). For example, device 100-1 recognizes the phrase "Meteorite Catcher" 4101 as the title of a movie, in <figref idref="f0552">Figure 41A</figref>. In some embodiments, the device uses a data detector stored in the memory of the device and/or stored remotely. In some embodiments, the device compares words/phrases in received messages to a predefined list of words and/or phrases stored within the memory or the device and/or stored remotely.

1545In response to detecting the word or phrase associated with additional content available on the internet, the device (7006): displays proximate to the first message region (e.g., bubble; for example, directly above or below the message), a selectable indication that additional content associated with the word or phrase is available (e.g., selectable text relating to the additional content, such as "see local show times," "make a reservation now"). For example, in response to recognizing the phrase "Meteorite Catcher" 4101 as the title of a movie, device 100-1 displays selectable indication 4104 ("See movie info") below message 4102, in <figref idref="f0552">Figure 41A</figref>.

1546In some embodiments, the word or phrase associated with additional content available is associated (7008) with a movie (e.g., a movie title, a distinctive or context-identifiable character name from the movie, or a famous line from a movie, such as, "show me the money"), and the additional content includes biographical data about the movie (e.g., the name of an actor/actress, the length of the move, the year the movie was released, or the studio that produced and/or distributed the movie), information on local performances of the movie (e.g., show times, theatre information, or a link to purchase tickets), ratings information for the movie (e.g., critic or user-contributed ratings, individual or compiled), and/or multi-media content about the movie (e.g., movie clips, streaming performances, or audio clips).

1547In some embodiments, the word or phrase associated with additional content available is associated (7010) with a television show (e.g., a show title, a distinctive or context-identifiable character name from the show, or an identifiable catch phrase, such as, "don't have a cow, man"), and the additional content includes biographical data about the show (e.g., the name of an actor/actress, the length of the series, information on the network, channel, and/or time the show is broadcasted; or the network that produced the show), ratings information about the show (e.g., critic or user-contributed ratings, individual or compiled), and/or multi-media content about the show (e.g., show clips, streaming performances, or audio clips).

1548In some embodiments, the word or phrase associated with additional content available is associated (7012) with a song or album (e.g., a song or album title, an artist name, or an identifiable line from the song or album, such as, "bye, bye, Miss American Pie"), and the additional content includes biographical data about the song or album (e.g., the name of an artist, composer, or producer of the song or album, the length of the song or album, songs on the album, the year the song or album was released, or the studio that produced and/or distributed the song or album), ratings information about the song or album (e.g., critic or user-contributed ratings, individual or compiled), and/or multi-media content about the song or album (e.g., audio clips or streaming performances).

1549In some embodiments, the word or phrase associated with additional content available is associated (7014) with a business (e.g., a particular type of business, such as restaurant, store, salon, or golf course, a business name, a distinctive or context-identifiable employee/owner name, or an identifiable slogan, such as, "pizza, pizza"), and the additional content includes biographical data about the business (e.g., an address, local street map, phone number, email address, or business hours), ratings information about the business (e.g., critic or user-contributed ratings (individual or compiled), and/or interactive content about the business (e.g., a website, an interactive ordering platform, or an interactive application associated with the business). In some embodiments, the business is a particular business, e.g., a specific restaurant. In some embodiments, the business is a class of businesses, e.g., a restaurant.

1550In some embodiments, the device (7016) detects an input that activates the selectable indication (e.g., detecting a tap gesture on the selectable indication) and, in response to detecting the input that activates the selectable indication, displaying additional content within the conversation transcript (e.g., displaying a drop-down window below the message bubble with additional content from the Internet). For example, in response to detecting an input that includes contact 4106 on selectable indication 4104, in <figref idref="f0553">Figure 41B</figref>, device 100-1 displays area 4108 including additional information (e.g., movie poster 4110 and biographical information 4112) about the "Meteorite Catcher" movie available on the Internet (e.g., device 100-1 displays selected Internet search results relating to the detected phrase).

1551In some embodiments, the additional content includes a link to a web content associated with the detected word or phrase (e.g., a link to a movie website or a link to a digital video that may be viewed and/or posted within the conversation transcript).

1552In some embodiments, the activatable indication is a stylized display of the recognized word or phrase within display of the received message (e.g., highlighting or coloring of the recognized word or phrase).

1553In some embodiments, the device detects in the first message, a word or phrase associated with additional content available on the Internet (e.g., information about a detected business/restaurant, music, movie, television show, current event, public figure, politician, celebrity, university, athlete, sporting event, or sports league/team). For example, device 100-1 recognizes the phrase "Astron Omer" 4103, in received message 4114, as the name of an actor, in <figref idref="f0555">Figure 41D</figref>. In some embodiments, the device uses a data detector stored in the memory of the device and/or stored remotely. In some embodiments, the device compares words/phrases in received messages to a predefined list of words and/or phrases stored within the memory or the device and/or stored remotely.

1554In some embodiments, in response to detecting the word or phrase associated with additional content available on the internet, the device stylizes the word or phrase within the message region and enables activation of the word or phrase in the message region. For example, in response to recognizing the phrase "Astron Omer" 4103 as the name of an actor, device 100-1 displays highlighting 4116 of "Astron Omer" within message 4114, in <figref idref="f0555">Figure 41D</figref>.

1555In some embodiments, the device detects an input that activates the stylized word or phrase in the message region (e.g., detecting a tap gesture on a highlighted word or phrase) and, in response, replaces display of the messaging user interface with display of an internet (and/or memory) search user interface for an internet search of the detected word or phrase, including a plurality of (e.g., categorized) search results. For example, in response to detecting an input, including contact 4118 on stylized phrase "Astron Omer," in <figref idref="f0556">Figure 41E</figref>, device 100-1 replaces display of messaging user interface with display of internet search user interface 3661, in <figref idref="f0557">Figure 41F</figref>, for an internet search of detected phrase "Astron Omer" 4103. Internet search user interface 3661 including a plurality of categorized search results relating to phrase "Astron Omer" 4103 (e.g., news articles 3664, 3678, 3680 and movie trailers 3670, 3682, and 3684).

1556In some embodiments, the device detects an input on a first search result in the plurality of search results in the Internet (and/or memory) search user interface and, in response, replaces display of the Internet (and/or memory) search user interface with the messaging user interface, displays a representation of the first search result in the conversation transcript of the messaging user interface, and transmits a representation of the first search result to the one or more electronic devices associated with other users of the messaging session (e.g., posts the search result to the messaging session).

1557For example, device 100-1 detects an input including contact 4120 on search result 3670, in <figref idref="f0558">Figure 41G</figref>, and, in response, replaces Internet search interface 3661 with messaging user interface 3500, including conversation transcript 3503 displaying representation of search result 3670.

1558It should be understood that the particular order in which the operations in <figref idref="f0614 f0615">Figures 70A-70B</figref> have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 600, 800, 1000, 1200, 1400, 1600, 1800, 2100, 2400, 2600, 2800, 3100, 3300, 4200, 4400, 4600, 4800, 5000, 5200, 5400, 5600, 5800, 6000, 6200, 6400, 6600, and 6800) are also applicable in an analogous manner to method 7000 described above with respect to <figref idref="f0614 f0615">Figures 70A-70B</figref>.

Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

1560As shown in <figref idref="f0616">Figure 71</figref>, an electronic device 7100 includes a display unit 7102 configured to display user interfaces; a touch-sensitive surface unit 7104 configured to detect contacts; and a processing unit 7106 coupled with the display unit 7102 and the touch-sensitive surface unit 7104, the processing unit 7106 including a detecting unit 7108, a receiving unit 7110 and a detecting unit 7112.

1561The processing unit 7106 is configured to enable display of (e.g., with enabling unit 7108) a messaging user interface of a messaging application on the display unit 7102, the messaging user interface including a conversation transcript of a messaging session between a user of the electronic device and at least one other user, and a message-input area. While displaying the messaging user interface, the processing unit 7106 is configured to receive (e.g., with receiving unit 7110) a first message within the messaging session from an electronic device that corresponds to another user included in the messaging session. In response to receiving the first message: the processing unit 7106 is configured to enable display of (e.g., with enabling unit 7108) the first message within a first message region in the conversation transcript on the display unit 7102. The processing unit 7106 is configured to detect (e.g., with detecting unit 7112), in the first message, a word or phrase associated with additional content available on the Internet. In response to detecting the word or phrase associated with additional content available on the internet, the processing unit 7106 is configured to enable display of (e.g., with enabling unit 7108), proximate to the first message region, a selectable indication that additional content associated with the word or phrase is available.

1562In some embodiments, the processing unit 7106 is further configured to: detect (e.g., with detecting unit 7112) an input that activates the selectable indication; in response to detecting the input that activates the selectable indication, enable display of (e.g., with enabling unit 7108) additional content within the conversation transcript.

1563In some embodiments, the word or phrase associated with additional content available is associated with a movie, and the additional content includes biographical data about the movie, information on local performances of the movie, ratings information for the movie, and/or multi-media content about the movie.

1564In some embodiments, the word or phrase associated with additional content available is associated with a television show, and the additional content includes biographical data about the show, ratings information about the show, and/or multi-media content about the show.

1565In some embodiments, the word or phrase associated with additional content available is associated with a song or album, and the additional content includes biographical data about the song or album, ratings information about the song or album, and/or multi-media content about the song or album.

1566In some embodiments, the word or phrase associated with additional content available is associated with a business, and the additional content includes biographical data about the business, ratings information about the business, and/or interactive content about the business.

1567The operations described above with reference to <figref idref="f0614 f0615">Figures 70A-70B</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref> or <figref idref="f0616">Figure 71</figref>. For example, detection operation 7016 is, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

The user interfaces in these figures are used to illustrate the processes described below, including the processes in <figref idref="f0785 f0788">Figures 73A-73D</figref>. For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch- sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

1569<figref idref="f0617 f0784">Figures 72A-72FM</figref> illustrate exemplary user interface 7200 for a messaging application. In <figref idref="f0617">Figure 72A</figref>, user interface 7200 includes conversation transcript 7202, message-input area 7204, activatable digital image affordance 7206, application affordance 7208, and application area 7210. Conversation transcript 7202 includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100 and another user included in the messaging session. The other user included in the messaging transcript is represented by an avatar (e.g., avatar 7210 for "Abe"). Message 7212 is a message received by device 100 from a remote device operated by a user identified as Abe and message 7214 is a message transmitted by device 100 to the remote device operated by Abe. In <figref idref="f0617">Figure 72A</figref>, application area 7210 displays a keyboard 7212.

1570In <figref idref="f0618">Figure 72B</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to application affordance 7208, as indicated by focus selector 7220. In response to the input, keyboard 7212, shown in the application area 7210 in <figref idref="f0618">Figure 72B</figref>, is replaced by an application input area 7222 and an application-selection area 7224, as shown in <figref idref="f0619">Figure 72C</figref>. From <figref idref="f0618 f0619">Figure 72B to Figure 72C</figref>, the appearance of application affordance 7208 has changed to indicate that an application mode is active. Application-selection area 7224 includes application-configuration affordance 7226 and application-selection affordances 7228 (for selecting a tic-tac-toe application), 7230 (for the currently displayed music application), and 7232 (for selecting a sticker application). Application-configuration affordance 7226 is also referred to herein as an application-selection affordance. Application input area 7222 includes application objects 7234, 7236, 7238, and 7240 (e.g., for selecting music track information to transmit to a remote device).

1571In <figref idref="f0620 f0623">Figures 72D-72G</figref>, an input (e.g., a scroll input) by a contact on touch screen 112 is detected, as indicated by focus selector 7242. As the focus selector 7242 moves along a path indicated by arrow 7244 from a first location on application-selection area 7224 (as shown in <figref idref="f0620">Figure 72D</figref>) to a second location on application-selection area 7224 (as shown in <figref idref="f0621">Figure 72E</figref>), the size of application selection objects 7228, 7230, and 7232 increases, and application-configuration affordance 7226 is no longer displayed in <figref idref="f0621">Figure 72E</figref>. As the focus selector 7242 continues to move across application-selection area 7224, as shown in <figref idref="f0621 f0622">Figures 72E-72F</figref>, application selection-affordance 7228 is no longer displayed and application-selection affordance 7246 is revealed. When the contact indicated by focus selector 7242 lifts off of touch screen 112, the sizes of application-selection affordances are decreased, as shown in <figref idref="f0622 f0623">Figures 72F-72G</figref>, and an additional application-selection affordance 7248 is revealed in <figref idref="f0623">Figure 72G</figref>.

In response to the input, application modification interface 72116 is displayed, as shown in <figref idref="f0645">Figure 72AC</figref>. Application modification interface 72116 displays toggle controls (e.g., toggle control 72122) and rearrangement controls (e.g., rearrangement control 72124) for messaging applications installed on device 100.

1583In <figref idref="f0646">Figure 72AD</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to toggle control 72118 for application management listing 7276, as indicated by focus selector 72122. In response to the input, a sticker application for messages that corresponds to the stickers application management listing 7276 is adjusted from a displayed state to a hidden state (e.g., as indicated by the altered appearance of toggle control 72112 in <figref idref="f0647">Figure 72AE</figref>. When the state of the sticker application for messages is a hidden state, the sticker application-selection affordance 7232 that corresponds to the sticker application for messages ceases to be displayed in application-selection area 7224 (e.g., as shown in <figref idref="f0657">Figure 72AO</figref>).

1584In <figref idref="f0648 f0649">Figure 72AF</figref>, a rearrangement input (e.g., a drag input) is detected by a contact on touch screen 112, as indicated by focus selector 72124. The rearrangement input selects the application management listing 72110 (e.g., after the focus selector 72124 remains proximate to a location that corresponds to rearrangement control 72120 for a duration of time increased beyond a threshold duration) and drags the application management listing 72110 upward to a new position, as shown at <figref idref="f0648 f0649 f0650 f0651 f0652 f0653">Figures 72AF to 72AJ</figref>. In <figref idref="f0617 f0668">Figure 72AK</figref>, the contact indicated by focus selector 72124 lifts off of the touch screen. In response to the lift off of the contact from the touch screen 112, in accordance with a determination that the rearrangement input met rearrangement criteria (e.g., movement of focus selector 72124 increased beyond a threshold distance), application management listing 72110 is dropped in the new position. As a result of the rearrangement input, an application-selection affordance 72126 for the tiny transit application that corresponds to application management listing 72110 is displayed in application-selection area 7224 between application selection affordance 7230 for the music application and application selection affordance 72128 for the reservations application (see, e.g., <figref idref="f0657">Figure 72AO</figref>).

1585In <figref idref="f0654">Figure 72AL</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to affordance 72130 for exiting application modification interface 72116, as indicated by focus selector 72132. In response to the input, application installation/deletion interface 7270 is redisplayed, as shown in <figref idref="f0655">Figure 72AM</figref>.

1586In <figref idref="f0656">Figure 72AN</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to affordance 72134 for exiting application installation/deletion interface 7270, as indicated by focus selector 72136. In response to the input, conversation transcript 7202 and application area 7210 are redisplayed in messaging user interface 7200, as shown in <figref idref="f0657">Figure 72AO</figref>.

Message Translation

1587<figref idref="f0658 f0728">Figures 72AP-72DI</figref> illustrate exemplary user interfaces for translating message content in a messaging application, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in <figref idref="f0793 f0796">Figures 75A-75D</figref> and <figref idref="f0797 f0799">76A-76C</figref>. For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch-sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

1588In conversation transcript 7202 of the messaging user interface 7200 shown in <figref idref="f0658">Figure 72AP</figref>, message bubbles 72138, 72142, and 72144 have message text in a language that matches the native language setting of device 100, and message bubble 72140 displays a message received by device 100 that includes foreign language text 72146.

In accordance with a determination that the characteristic intensity of the contact increases above light press intensity threshold level IT_L, translation 72150 of the foreign language text is displayed in message bubble 72140. In <figref idref="f0727">Figure 72DH</figref>, in accordance with a determination that the characteristic intensity of the contact increases above a deep press intensity threshold level IT_D as indicated by intensity level meter 72155, translation 72150 of the foreign language text is persistently displayed in message bubble 72140 (e.g., continuing after the contact indicated by focus selector 72214 lifts off of touch screen 112, as shown in <figref idref="f0728">Figure 72DI</figref>). Additionally, in accordance with the determination that the characteristic intensity of the contact has increased above deep press intensity threshold level ITD, the visual appearance of the translated text 72150 is changed (e.g., compared with the visual appearance of the translated text 72150 in <figref idref="f0726">Figure 72DG</figref>) to provide an indication to the user of the persistent nature of the translation.

Bubble Connections

1611<figref idref="f0729 f0767">Figures 72DJ-72EV</figref> illustrate exemplary user interfaces for connecting message bubbles in a messaging application, in accordance with some embodiments. For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch-sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

1612In <figref idref="f0729">Figure 72DJ</figref>, user interface 7200 includes conversation transcript 7202 that includes messages from participants of a corresponding messaging session, including the user of portable multifunction device 100-A ("Riley") and a user of portable multifunction device 100-B ("Ray") included in the messaging session. On device 100-A, the user "Ray" is represented by an avatar 72216. Message 72218 is a message received by device 100-A from remote device 100-B operated by the user identified as Ray and message 72224 is a message transmitted by device 100-A to the remote device 100-B operated by Riley.

1613<figref idref="f0729 f0749">Figures 72DJ -72ED</figref> illustrate input used for grouping message content (e.g., for connecting message bubbles displayed in conversation transcript 7202). In some embodiments, the grouping selection input groups first content (e.g., one or more received messages in the conversation transcript, one or more sent messages in the conversation transcript, and/or input content entered in a message-input area) in a messaging user interface with at least one message (e.g., one or more received messages in the conversation transcript and/or one or more sent messages in the conversation transcript) that is displayed in the messaging user interface. In response to detecting the grouping selection input, a group that includes the first content and the at least one message is created.

1614In some embodiments, input for connecting message bubbles includes input to put a message bubble in a grouping mode, as illustrated at <figref idref="f0733 f0737">Figures 72DN-72DR</figref> and <figref idref="f0738 f0740">72DS-72DU</figref>. In some embodiments, input for connecting message bubbles includes input to move a message bubble, as illustrated at <figref idref="f0734 f0736">Figures 72DO-72DQ</figref> and <figref idref="f0741">Figures 72DV-72DY</figref>. In some embodiments, input for connecting message bubbles includes input for drawing a connection between message bubbles, as illustrated at <figref idref="f0746 f0749">Figures72EA-72ED</figref>.

1615In some embodiments, a grouping selection input is an input detected at a location that corresponds to the first content (e.g., message bubble 72218) and the grouping selection input moves the first content from a first location to a second location (e.g., as shown in <figref idref="f0620">Figures 72D</figref>)-72DQ) within the messaging user interface 7200. In some embodiments, the grouping selection input drags a message in a direction (e.g., left to right or right to left) by a distance that meets one or more grouping criteria. <figref idref="f0734 f0744">Figures 72DO-72DY</figref> illustrate a grouping selection input that includes dragging a first message bubble 72218 and a second message bubble 72224 to grouping positions (e.g., proximate to the center of messaging user interface 7200).

1616In <figref idref="f0730">Figure 72DK</figref>, a grouping mode input (e.g., a press input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72218, as indicated by focus selector 72220, and a characteristic intensity of the gradually increases, as shown in <figref idref="f0730 f0732">Figures 72DK-72DM</figref>, until the characteristic intensity of the contact has increased above a deep press intensity threshold level IT_D as indicated by intensity level meter 72155, as shown in <figref idref="f0732">Figure 72DM</figref>. In accordance with a determination that the characteristic intensity of the contact has increased above the deep press intensity threshold level IT_D, message bubble 72218 enters a grouping mode. In some embodiments, when the message bubble 72218 enters the grouping mode, the message bubble 72218 is "detached" from conversation transcript 7202 such that the message bubble 72218 is movable within conversation transcript 7202. In some embodiments, to indicate that message bubble 72218 is in a grouping mode, the device provides an indication that the message is detached from the transcript, such as an altered background, haptic feedback, an altered transcript characteristic, and/or an altered message bubble characteristic. For example, a message bubble outline is altered (e.g., shown with a greater line weight, as shown in <figref idref="f0733">Figure 72DN</figref>), the bubble size is increased, and/or the appearance of text in the message bubble is altered to provide a visual indication that message bubble 72218 is in a grouping mode. The input that transitions message bubble 72218 to a grouping mode allows a swipe input at a location that corresponds to message bubble 72218 to have a grouping functionality when the message bubble is in a grouping mode and an alternative functionality (e.g., horizontally dragging one or more displayed message bubbles to reveal a time that corresponds to the one or more message bubbles) when the message bubble is not in a grouping mode.

1617In some embodiments, grouping selection input as described herein occurs without transitioning a message bubble to a grouping mode using a grouping mode input.

1618In some embodiments, detecting the grouping selection input includes detecting a first input (e.g., a deep press input) at a location that corresponds to the first content and a second input (e.g., a deep press input) at a location that corresponds to the at least one message.

1619In <figref idref="f0734">Figure 72DO</figref> a grouping selection input (e.g., a drag input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72218, as indicated by focus selector 72222. The input drags the message bubble 72218 toward a grouping position (e.g., proximate to the center of messaging user interface 7200), as shown at <figref idref="f0734 f0735 f0736">Figures 72DO to 72DQ</figref>. In <figref idref="f0737">Figure 72DR</figref>, after movement of message bubble 72218 has met grouping criteria (e.g., the message bubble has moved to the grouping position), the contact indicated by focus selector 72222 lifts off of the touch screen 112. In some embodiments, in accordance with a determination that movement of message bubble 72218 has met grouping criteria (e.g., the message bubble has moved to the grouping position), a visual appearance of message bubble 72218 is altered and/or a haptic effect occurs to indicate to the user that the message bubble has been moved to a grouping position.

1620In <figref idref="f0738">Figure 72DS</figref>, a grouping mode input (e.g., a press input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72224, as indicated by focus selector 72226, and a characteristic intensity of the gradually increases, as shown in <figref idref="f0738 f0739">Figures 72DS-72DT</figref>, until the characteristic intensity of the contact has increased above a deep press intensity threshold level IT_D as indicated by intensity level meter 72155, as shown in <figref idref="f0739">Figure 72DT</figref>. In accordance with a determination that the characteristic intensity of the contact has increased above the deep press intensity threshold level IT_D, message bubble 72224 enters a grouping mode.

1621In <figref idref="f0741">Figure 72DV</figref> a grouping selection input (e.g., a drag input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72224, as indicated by focus selector 72228. The grouping selection input drags the message bubble 72224 toward a grouping position (e.g., proximate to the center of messaging user interface 7200), as shown at <figref idref="f0741 f0742 f0743">Figures 72DV to 72DX</figref>. In <figref idref="f0744">Figure 72DY</figref>, after movement of message bubble 72218 has met grouping criteria (e.g., the message bubble has moved to the grouping position), the contact indicated by focus selector 72228 lifts off of the touchscreen. In some embodiments, in accordance with a determination that movement of message bubble 72224 has moved to the grouping position, a visual appearance of message bubble 72224 is altered and/or a haptic effect occurs to indicate to the user that the message bubble has been moved to a grouping position. In response to lift off of the contact, a group of message bubbles 72218 and 72224 is formed (e.g., in accordance with a determination that more than one message bubble has been dragged to a grouping position by the grouping selection input), as indicated by grouping indicator 72230.

1622In some embodiments, grouping indicia are displayed at a first location that corresponds to the first content (e.g., message bubble 72218) and at a second location that corresponds to the at least one message (e.g., message bubble 72224). For example, grouping indicia include a line (e.g., grouping indicator 72230 or 72236) that connects the first content with the at least one message, a region designator (e.g., a shape, such as a box, that encompasses the first content and the at least one messages), and/or a plurality of markers (e.g., a first marker displayed at a location that corresponds to the first content and a second marker displayed at a location that corresponds to the at least one message.

1623<figref idref="f0746">Figures 72EA-72ED</figref> illustrate a grouping selection input that includes a swipe input from a first message bubble 72218 to a second message bubble 72224. In <figref idref="f0746">Figure 72EA</figref>, a grouping selection input (e.g., a swipe input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72218, as indicated by focus selector 72232. In some embodiments, the grouping selection input is detected after message bubble 72218 has transitioned to a grouping mode. As the grouping selection input is received, a line 72234 is displayed to indicate the path of the grouping selection input, as illustrated at <figref idref="f0747 f0748">Figures 72EB-72EC</figref>. In <figref idref="f0749">Figure 72ED</figref>, the contact indicated by focus selector 72232 has lifted off from touch-sensitive surface 112, an line 72234 is replaced by grouping indicator 72236.

1624<figref idref="f0750">Figure 72EE</figref> shows messages 72218 and 72224 in a group (as indicated by group indicator 72236) displayed on portable multifunction device 100-B.

1625In some embodiments, a second input is detected that indicates second content to add to the created group. For example, in <figref idref="f0751">Figure 72EF</figref>, text input 72238 has been entered in message input area 72240 displayed on device 100-B. An input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to send affordance 72242, as indicated by focus selector 72244. In <figref idref="f0752">Figure 72EG</figref>, text input 72238 is displayed in message bubble 72246 as a sent message in conversation transcript 7202.

1626In <figref idref="f0753">Figure 72EH</figref>, message bubble 72246 is shown in a grouping mode state. For example, a grouping mode input as described with regard to <figref idref="f0730 f0733">Figures 72DK-72DN</figref> is provided to transition message bubble 72246 to a grouping mode state.

1627In <figref idref="f0754">Figure 72EI</figref>, a grouping selection input (e.g., a drag input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72246, as indicated by focus selector 72248. The grouping selection input drags the message bubble 72246 toward a grouping position (e.g., proximate to the center of messaging user interface 7200), as shown at <figref idref="f0754 f0755 f0756">Figures 72EI to 72EK</figref>. In <figref idref="f0757">Figure 72EL</figref>, after movement of message bubble 72246 has met grouping criteria (e.g., the message bubble has moved to the grouping position), the contact indicated by focus selector 72248 lifts off of the touchscreen. In response to lift off of the contact, in accordance with a determination that grouping criteria have been met, message bubble 72246 is added to a group with message bubble 72218 and 72224, as indicated by grouping indicator 72236.

1628<figref idref="f0758">Figure 72EM</figref> shows messages 72218, 72224, and 72246 in a group (as indicated by group indicator 72236) displayed on portable multifunction device 100-A. Text input 72250 has been entered in message input area 7204 displayed on device 100-A. The size of the text input in message input area 7204 causes message bubbles in the group indicated by group indicator 72236 to move upward. In order to continue to display uppermost message bubble 72218 of the group, uppermost message bubble 72218 is displayed overlapping non-group messages 72258, 72260, and 72262 (which are shown in a dimmed area of the display to avoid confusion between the non-group messages and the overlying group messages).

1629In some embodiments, the first content is input content entered in the message-input area (e.g., input received prior to transmitting a message including input content), and the grouping selection input is detected prior to a transmission input that transmits the message to another device (e.g., as illustrated at <figref idref="f0758 f0763">Figures 72EM-72ER</figref>).

1630In <figref idref="f0759">Figure 72EN</figref>, a grouping selection input (e.g., a drag input) by a contact on touch screen 112 is detected at a location that corresponds to send affordance 72254, as indicated by focus selector 72256. The grouping selection input drags the message bubble 72256 toward a group member (e.g., to a location that partially overlaps a message bubble in the group), as shown at <figref idref="f0759 f0760">Figures 72EN to 72EO</figref>. In <figref idref="f0761">Figure 72EP</figref>, after movement of message bubble 72246 has met grouping criteria (e.g., the message bubble has moved a location that partially overlaps message bubble 72246), the contact indicated by focus selector 72256 lifts off of the touch screen 112. In <figref idref="f0762">Figure 72EQ</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to send affordance 72254, as indicated by focus selector 72266. As shown in <figref idref="f0763">Figure 72ER</figref>, in response to the input, message bubble 72264 is added to a group with message bubbles 72218, 72224, and 72246, as indicated by grouping indicator 72236.

1631In some embodiments, in response to lift off of the contact indicated by focus selector 72256, in accordance with a determination that grouping criteria have been met, message bubble 72264 is added to a group with message bubbles 72218, 72224, and 72246, as indicated by grouping indicator 72236.

1632<figref idref="f0764">Figure 72ES</figref> indicates an input (e.g., a tap input) by a contact on touch screen 112 at a location shown by focus selector 72268 (e.g., a location that does not correspond to any of the message bubbles or affordances displayed in messaging user interface 7200). In response to the input, the grouped messages cease to overlap the non-grouped messages (e.g., message bubble 72218 ceases to be displayed such that message bubble 72218 ceases to overlap message bubble 72258). <figref idref="f0766">Figure 72EU</figref> indicates an input (e.g., a tap input) by a contact on touch screen 112 at a location that corresponds to group indicator 72236, as shown by focus selector 72270. In response to the input, the grouped message bubbles are displayed overlapping the non-grouped messages, such that grouped message bubbles 72218, 72224, 72246, and 72264 are simultaneously displayed, as shown in Figure EV.

Message Flagging

1633<figref idref="f0768 f0784">Figures 72EW-72FM</figref> illustrate exemplary user interfaces for flagging a message bubble, in accordance with some embodiments. For example, in response to an input that designates a message bubble in a conversation transcript 7202, the message bubble is flagged (e.g., the message bubble is displayed at a fixed location on the display, such as at the top of the conversation transcript 7202). For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 450 and a separate touch- sensitive surface 451 in response to detecting the contacts on the touch-sensitive surface 451 while displaying the user interfaces shown in the figures on the display 450, along with a focus selector.

1634In <figref idref="f0768">Figure 72EW</figref>, user interface 7200 includes conversation transcript 7202 that includes messages from participants of a corresponding messaging session. Conversation transcript 7202 includes a received message displayed in message bubble 72218.

1635In <figref idref="f0769">Figure 72EX</figref>, a flagging mode input (e.g., a press input) by a contact on touch screen 112 is detected at a location that corresponds to message bubble 72272, as indicated by focus selector 72274, and a characteristic intensity of the gradually increases, as shown in <figref idref="f0769 f0771">Figures 72EX-72EZ</figref>, until the characteristic intensity of the contact has increased above a deep press intensity threshold level IT_D as indicated by intensity level meter 72155, as shown in <figref idref="f0771">Figure 72EZ</figref>. In accordance with a determination that the characteristic intensity of the contact has increased above the deep press intensity threshold level IT_D, message bubble 72272 enters a flagging mode. In some embodiments, when the message bubble 72272 enters the flagging mode, the message bubble 72272 is "detached" from conversation transcript 7202 such that the message bubble 72272 is movable within conversation transcript 7202. In some embodiments, to indicate that message bubble 72272 is in a grouping mode, the device provides an indication that the message is detached from the transcript, such as an altered background, haptic feedback, an altered transcript characteristic, and/or an altered message bubble characteristic. For example, a message bubble outline is altered (e.g., shown with a greater line weight, as shown in <figref idref="f0772">Figure 72FA</figref>), the bubble size is increased, and/or the appearance of text in the message bubble is altered to provide a visual indication that message bubble 72272 is in a flagging mode.

1636In some embodiments, flagging selection input as described herein occurs without transitioning a message bubble to a flagging using a flagging mode input.

1637In some embodiments, in response to an input (e.g., a flagging mode input and/or a flagging selection input) that designates a message (e.g., a message in message bubble 72272) in a conversation transcript 7202, the message is displayed at a fixed location on the display 112, such as at the top of the conversation transcript 7202. In some embodiments, the input that designates the message is a tap input on the message bubble followed by selection of a menu item, a press and hold input (e.g., an input that meets predetermined duration criteria during which a contact remains in contact with touch screen 112), and/or a press input (e.g., an input with a characteristic intensity of the contact that exceeds a threshold intensity level, such as a light press intensity threshold level IT_L and/or a deep press intensity threshold level IT_D). In some embodiments, the input is a drag input that drags the message to the fixed location on the display. In some embodiments, when the input moves the message beyond a threshold distance, the message is "detached" from the conversation transcript 7202. In some embodiments, in response to detecting the input, the message is detached from the conversation transcript and/or automatically moved to the fixed location on the display (e.g., an animation is shown in which the message moves from its original location on the display to the fixed location on the display).

1638In <figref idref="f0773">Figure 72FB</figref>, a flagging selection input (e.g., a drag input) is detected by a contact on touch screen 112, as indicated by focus selector 72276. The flagging selection input drags the message bubble 72272 toward the top of conversation transcript 7202, as shown at <figref idref="f0774 f0775 f0776">Figures 72FC to 72FE</figref>. In some embodiments, a placeholder 72278 for message bubble 72218 is displayed in the conversation transcript 7202. In <figref idref="f0777">Figure 72FF</figref>, the contact indicated by focus selector 72276 lifts off of the touch screen 112. In response to the lift off of the contact from touch screen 112, in accordance with a determination that the flagging selection input met flagging criteria (e.g., movement of the focus selector 72276 increased beyond a threshold distance), message bubble 72272 is dropped at the top of conversation transcript 7202.

1639In <figref idref="f0777">Figure 72FF</figref>, message bubble 72272 is displayed in a message banner 72280 at the top of conversation transcript 7202. In <figref idref="f0654">Figure 72AL</figref>, an input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to affordance 72130 for exiting application modification interface 72116, as indicated by focus selector 72132. In response to the input, application installation/deletion interface 7270 is redisplayed, as shown in <figref idref="f0655">Figure 72AM</figref>.

1640In some embodiments, a timer 72282 is displayed that indicates the elapsed time since the message was flagged.

1641In some embodiments, when a message that responds to the flagged message is transmitted, a flagged message is unflagged and returns to its previous location in the transcript. For example, in <figref idref="f0778">Figure 72FG</figref>, text input 72284 has been entered in message input area 7204. An input (e.g., a tap input) by a contact on touch screen 112 is detected at a location that corresponds to send affordance 72290, as indicated by focus selector 72286. In <figref idref="f0779">Figure 72FH</figref>, text input 72284 is displayed in message bubble 72292 as a sent message in conversation transcript 7202.

1642In some embodiments, a second input (e.g., dragging the message in a direction that is opposite to the direction in which the message was dragged to flag the message) is received that returns a flagged message to its previous position (e.g., to unflag the message). For example, in <figref idref="f0780">Figure 72FI</figref>, a flagging deselection input (e.g., a drag input) is detected by a contact on touch screen 112, as indicated by focus selector 72294. The flagging selection input drags the message bubble 72272 toward its original location (e.g., indicated by placeholder 72278), as shown at <figref idref="f0780 f0781 f0782 f0783">Figures 72FI to 72FL</figref>. In <figref idref="f0784">Figure 72FM</figref>, the contact indicated by focus selector 72294 lifts off of the touch screen 112. In response to the lift off of the contact from touch screen 112, in accordance with a determination that the flagging selection input meet unflagging criteria (e.g., movement of the focus selector 72294 increased beyond a threshold distance), message bubble 72272 is dropped at its original location within conversation transcript 7202.

1643In some embodiments, a flagging mode input is received (e.g., while message 72272 is displayed at the flagged position and/or prior to a flagging deselection input.

1644<figref idref="f0785 f0788">Figures 73A-73D</figref> are flow diagrams illustrating a method 7300 for navigating between applications using an application user interface displayed in a messaging user interface, in accordance with some embodiments. The method 7300 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 7300 are, optionally, combined and/or the order of some operations is, optionally, changed.

1645The device displays (7302), on a display (e.g., touch screen 112), a messaging user interface (7200, <figref idref="f0617">Figure 72A</figref>), the messaging user interface including: a conversation transcript 7202 of a messaging session between a user of the electronic device and at least one other user, a message-input area 7204, an application area 7210, and an application-area-display affordance. In some embodiments, application area 7210 is a predefined area in the messaging user interface 7200, separate from the conversation transcript 7202 and the message-input area 7204, that is configured to display either a keyboard 7212 or activatable objects (e.g., objects 7234-7240, <figref idref="f0619">Figure 72C</figref>) that correspond to one or more applications that operate within the messaging user interface 7200 of a messaging application.

1646While displaying the messaging user interface 7200, the device detects (7304) a first input (e.g., a tap input by a contact at a location indicated by focus selector 7220, <figref idref="f0618">Figure 72B</figref>) that activates the application-area-display affordance 7208.

1647In response to detecting the first input that activates the application-area-display affordance 7208, in accordance with a determination that the application area is displaying a keyboard 7212 at the time the first input is detected, the device replaces (7306) display of the keyboard 7212 in the application area with concurrent display of: an application-selection area 7224 (<figref idref="f0619">Figure 72C</figref>) that displays a plurality of scrollable application-selection affordances (e.g., 7226-7232) and an application-input area 7222 that displays one or more activatable objects (e.g., 7234-7240) of the first application. In some embodiments, the plurality of scrollable application-selection affordances are arranged in a single horizontal row. The plurality of scrollable application-selection affordances includes a first application-selection affordance (e.g., 7230) that corresponds to a first application that is currently selected (e.g., the music application that includes activatable objects 7234-7240 displayed in application-input area 7222). A respective application-selection affordance (e.g. application-selection affordance 7230) has a respective first size.

1648While concurrently displaying the application-selection area 7224 and the application-input area 7222, the device detects (7308) a second input that includes a movement of a contact on the touch-sensitive surface that corresponds to movement of a focus selector 7242 (<figref idref="f0620">Figure 72D</figref>) in a first direction in the application-selection area 7224 on the display (e.g., a horizontal drag or swipe gesture by the contact within the application-selection area on touch screen 112).

1649In response to detecting the second input, the device scrolls (7310) the plurality of application-selection affordances in the first direction (e.g., as shown at <figref idref="f0620 f0623">Figures 72D-72G</figref>) and displays a second application-selection affordance (e.g., application-selection affordance 7426, <figref idref="f0623">Figure 72G</figref>). In some embodiments, the second application-selection affordance was not displayed prior to the scrolling.

1650While displaying the second application-selection affordance and the one or more activatable objects of the first application in the messaging user interface, the device detects (7312) a third input (e.g., a tap input by a contact at a location indicated by focus selector 7250, <figref idref="f0624">Figure 72H</figref>) that activates the second application-selection affordance (e.g., 7426).

1651In response to detecting the third input that activates the second application-selection affordance, the device (7314) ceases to display the one or more activatable objects of the first application (e.g., 7234-7240) and displays, in the application-input area, one or more activatable objects of a second application that corresponds to the second application-selection affordance (e.g., the device displays activatable objects 7252 and 7254 of a reservations application, as indicated in <figref idref="f0625">Figure 72I</figref>).

1652Displaying an application-selection area that displays a plurality of scrollable application-selection affordances presents a user with a limited number of initially displayed application-selection affordances while providing the user with quick access to additional application-selection affordances. Presenting a limited number of initially displayed application-selection affordances allows the user to quickly select an application (e.g., from among a short list of pre-selected and/or most used applications) and reduces the likelihood of accidental selection of an application affordance. Enabling the user to use the device more quickly and efficiently reduces power usage and improves battery life of the device.

1653In some embodiments, while scrolling the plurality of application-selection affordances in the first direction, for at least some of the scrolling application-selection affordances, the device increases (7316) the size of a respective application-selection affordance from the respective first size to a respective second size, larger than the respective first size. For example, while scrolling of application-selection affordances occurs, application-selection affordance 7230 increases from a first size, as shown in <figref idref="f0619">Figure 72C</figref>, to a second size, as shown in <figref idref="f0621">Figure 72E</figref>. In some embodiments, increasing the size of the respective application-selection affordance includes displaying an animated transition (e.g., that gradually increases the size of the respective application-selection affordance from the respective first size to the respective second size). In some embodiments, all displayed application-selection affordances increase in size temporarily during scrolling (e.g., as shown in <figref idref="f0621">Figure 72E</figref>, application-selection affordances 7232, 7230, and 7228 have all increased in size relative to their respective sizes in <figref idref="f0619">Figure 72C</figref>). In some embodiments, a size of the application-selection area 7224 increases temporarily during scrolling. In some embodiments, a magnitude of the increase in size of the one or more application selection affordances is dependent on a speed at which the scrolling occurs (e.g., a greater scrolling speed results in a larger (e.g., proportionally larger) increase in the size of the one or more application selection affordances). Increasing the size of the application-selection affordances during scrolling makes it easier for a user to locate the application-selection affordance that corresponds to the application that the user wants to select and use within the messaging application.

1654Increasing the size of a respective application-selection affordance while scrolling the plurality of scrollable application-selection affordances increases the visibility of the respective application-selection affordance. Increasing the visibility of an application-selection affordance enhances the operability of the device by making the desired application selection affordance easier for the user to select (e.g., by providing a larger selectable area that corresponds to the application-selection affordance) and reduces the likelihood of accidental selection of an application selection affordance other than the desired application selection affordance (e.g., by making an icon that corresponds to the desired application-selection affordance easier for the user to see).

1655In some embodiments, after scrolling the plurality of application-selection affordances in the first direction, the device decreases (7318) the size of the respective application-selection affordance from the respective second size to the respective first size. For example, after scrolling of application-selection affordances occurs, application-selection affordance 7230 decreases from the second size, as shown in <figref idref="f0621">Figure 72E</figref> to the its initial size, as shown in <figref idref="f0623">Figure 72G</figref>. In some embodiments, the size of the respective application-selection affordance decreases when scrolling stops, or within a predetermined time after scrolling stops. In some embodiments, decreasing the size of the respective application-selection affordance includes displaying an animated transition (e.g., that gradually decreases the size of the respective application-selection affordance from the respective second size to the respective first size).

1656Decreasing the size of a respective application-selection affordance after scrolling the plurality of scrollable application-selection affordances allows an increased number of application-selection affordances to be simultaneously displayed. Increasing the number of simultaneously displayed application-selection affordances makes the user-device interface more efficient (e.g., by increasing the number of application-selection affordances available for selection without further scrolling input).

1657In some embodiments, while scrolling the plurality of application-selection affordances in the first direction, the device reduces (7320) a number of application-selection affordances shown in the application-input area from a first number of application-selection affordances (e.g., the four application-selection affordances 72226, 7228, 7230, and 7232 shown in <figref idref="f0620">Figure 72D</figref>) to a second number of application-selection affordances (e.g., the three application-selection affordances 7228, 7230, and 7232 shown in <figref idref="f0621">Figure 72E</figref>) that is less than the first number of application-selection affordances.

1658Reducing the number of application-selection affordances displayed while scrolling the plurality of scrollable application-selection affordances reduces the likelihood of accidental selection of an application selection affordance other than the desired application selection affordance (e.g., by increasing the distance between the centers of the application-selection affordances).

1659In some embodiments, after scrolling the plurality of application-selection affordances in the first direction, the device ceases (7320) to display at least one application-selection affordance of the plurality of scrollable application-selection affordances that was displayed prior to scrolling the plurality of application-selection affordances in the first direction. For example, application-selection affordance 7228, shown in <figref idref="f0619">Figure 72C</figref> prior to scrolling, is no longer displayed in application-selection area 7224 after scrolling, as shown in <figref idref="f0623">Figure 72G</figref>.

1660Ceasing to display at least one application-selection affordance after scrolling allows the user to view additional application selection affordances in the display space that is made available by ceasing to display the at least one application selection affordance. This increases the operability of the device (e.g., by increasing a number of application-selection affordances that can be viewed and selected via a scrolling process).

1661In some embodiments, while the application-input area 7222 is displayed at a first size, the device (7324) displays, in the application-input area, an application-input area expansion affordance (e.g., chevron 7260) and detects a fourth input that activates the application-input area expansion affordance 7260. For example, the fourth input includes movement of a contact on the touch-sensitive surface that corresponds to movement of the focus selector 7256 in a second direction (e.g., different from the first direction) that drags the application-input area expansion affordance 7260 (e.g., upwards). In some embodiments, the fourth input is a tap input on the application-input area expansion affordance 7260. In response to detecting the fourth input, the device increases a size of the application-input area 7222 from the first size (as shown in <figref idref="f0626">Figure 72J</figref>) to a second size that is larger than the first size (e.g., as shown in <figref idref="f0627">Figure 72K</figref> or <figref idref="f0628">72L</figref>). In some embodiments, while the size of the application-input area is the second size, the conversation transcript 7202 of the messaging session (e.g., including at least one message) is at least partially displayed in the messaging user interface (e.g., as shown in <figref idref="f0627">Figure 72K</figref>).

1662Increasing a size of the application-input area in response to input that activates an application-input area expansion affordance allows an increased number of activatable objects of an application to be simultaneously displayed in the application-input area. Increasing a number of activatable objects of an application that are simultaneously displayed in the application-input area makes the user-device interface more efficient by reducing the number of inputs required to navigate to a desired activatable object of an application.

1663In some embodiments, in response to detecting the first input that activates the application-area-display affordance 7264 (e.g., a tap input by a contact at a location indicated by focus selector 7264, <figref idref="f0631">Figure 72O</figref>), in accordance with a determination that the application area 7210 is displaying the application-selection area 7224 and the application-input area 7222 in the application area 7210 at the time the first input is detected, the device replaces (7326) display of the application-selection area 7224 and the application-input area 7222 in the application area with display of the keyboard 7212, as shown in <figref idref="f0631 f0632">Figures 72O-72P</figref>. In some embodiments, in response to detecting an input (e.g., a tap input) on the application-area-display affordance 7208 (or in the message-input area 7204), in accordance with a determination that the messaging user interface is displaying the application-selection area 7224 and the application-input area 7222 at the time the input is detected, display of the application-selection area 7224 and the application-input area 7222 is replaced with display of the keyboard 7212.

1664Replacing display of the application-selection area 7224 and the application-input area 7222 in the application area 7210 with display of the keyboard 7212 in response to input that activates an application-area-display affordance 7208 enhances the operability of the device by reducing the amount of display area consumed by these elements by alternatively displaying the elements. Reducing the amount of display area consumed by these elements enhances the operability of the device by increasing the display area available to display other user interface objects.

1665In some embodiments, while displaying, in the application-input area 7222, the one or more activatable objects (e.g., 7252 and 7254) of the second application, the device detects (7328) a fifth input (e.g., a tap input by a contact at a location indicated by focus selector 7264, <figref idref="f0631">Figure 72O</figref>) that activates the application-area-display affordance 7208. In response to detecting the fifth input that activates the application-area-display affordance 7208, the device replaces concurrent display of the application-selection area 7224 and the application-input area 7222 with display of the keyboard 7212 (e.g., as shown in <figref idref="f0631 f0632">Figures 72O-72P</figref>). While displaying the keyboard 7212 in the application area, the device detects a sixth input (e.g., a tap input by a contact at a location indicated by focus selector 7264, <figref idref="f0633">Figure 72Q</figref>) that activates the application-area-display affordance 7208. In response to detecting the sixth input that activates the application area-display affordance, the device ceases to display the keyboard 7212 in the application area, and concurrently displays the application-selection area 7224 and the application-input area 7222 (e.g., as shown in <figref idref="f0633 f0634">Figures 72Q-72R</figref>), wherein the application-selection area 7224 concurrently displays a pre-selected set of application-selection affordances (e.g., the set of 7226, 7228, 7230, and 7232) that includes the first application-selection affordance (e.g., 7230). For example, the pre-selected set of application-selection affordances are a default set of application-selection affordances or a set of user-selected application selection affordances that are displayed. In some embodiments, the pre-selected set of application-selection affordances are shown each time input that activates the application area-display affordance causes the application-selection area to be displayed.

1666Displaying a pre-selected set of application-selection affordances (e.g., the set of 7226, 7228, 7230, and 7232) in response to an input that activates an application area-display affordance 7208 allows the user to quickly navigate to a desired activatable object that corresponds to an application (e.g., a frequently used application) in a pre-selected set of applications. For example, after scrolling the plurality of application-selection affordances, the user is enabled to return to a pre-set of most used application-selection affordances by providing an input that activates an application area-display affordance (rather than needing to reverse the scrolling of the plurality of application selection affordances). In this way, the number of inputs and/or time during which input must be provided is reduced.

1667It should be understood that the particular order in which the operations in <figref idref="f0785 f0788">Figures 73A-73D</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 7300 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 7300 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

1668The operations described above with reference to <figref idref="f0785 f0788">Figures 73A-73D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>. For example, one or more of the operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1669<figref idref="f0789 f0792">Figures 74A-74D</figref> are flow diagrams illustrating a method 7400 for managing applications used within a messaging application, in accordance with some embodiments. The method 7400 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 7400 are, optionally, combined and/or the order of some operations is, optionally, changed.

1670The device displays (7402), by a display (e.g., touch screen 112), a messaging user interface 7200 (<figref idref="f0619">Figure 72C</figref>) of a messaging application. The messaging user interface includes a conversation transcript 7202 of a messaging session between a user of the electronic device and at least one other user; a message-input area 7204; and an application area 7210 (e.g. a predefined area in the messaging user interface, separate from the conversation transcript and the message-input area, that is configured to display either a keyboard or activatable objects that correspond to one or more applications that are displayed within the messaging user interface of a messaging application). The application area 7210 includes an application-input area 7222 that displays one or more activatable objects (e.g., 7234-7240) of a first application and an application-selection area 7224. The application-selection area 7224 includes a plurality of scrollable application-selection affordances (e.g., 7228-7232) that correspond to a plurality of applications that operate within the messaging user interface and a first application-configuration affordance (e.g., 7226). In some embodiments, the application-selection affordances are arranged in a single horizontal row.

1671While displaying the application-configuration affordance 7226 in the application-selection area 7224, the device detects (7404) a first input (e.g., a tap input by a contact at a location indicated by focus selector 7268, <figref idref="f0635">Figure 72S</figref>) that activates the first application-configuration affordance 7226.

1672In response to detecting the first input, the device displays (7406) a first application-management interface 7270 (<figref idref="f0636">Figure 72T</figref>) for the messaging application that includes a plurality of installed-application affordances (e.g., 7273, 7275, 7277, 7279, 7281, 7283, 7285) that correspond to the plurality of applications that operate within the messaging user interface of the messaging application, and a second application-configuration affordance 72112 that is distinct from the first application-configuration affordance 7226.

1673While displaying the first application-management interface 7270, the device detects (7408) a second input (e.g., a tap input by a contact at a location indicated by focus selector 7288, <figref idref="f0637">Figure 72U</figref>) at a location that corresponds to a first installed-application affordance 7273 of the plurality of installed-application affordances, wherein the first installed-application affordance 7273 corresponds to a first installed application on the electronic device (e.g., a tic-tac-toe application).

1674In response to detecting the second input, the device initiates (7410) a process to uninstall at least a component of the first installed application on the mobile device (e.g., a component of the first installed application that operates within one or more user interfaces, such as the messaging user interface, a watch user interface, and/ or a content sharing user interface, is uninstalled). In some embodiments, at least a component of the first installed application remains installed on the device when the component of the first installed application is uninstalled. For example, a component of the application that is accessible from the device home screen remains installed.

1675While displaying the first application-management interface, the device detects (7412) a third input (e.g., a tap input by a contact at a location indicated by focus selector 72212, <figref idref="f0644">Figure 72AB</figref>) at a location that corresponds to the second application-configuration affordance 72112.

1676In response to detecting the third input, the device displays (7414) a second application-management interface 72116 (<figref idref="f0645">Figure 72AC</figref>) for the messaging application. The second application-management interface 72116 includes a plurality of toggles (e.g., 72117, 72118, 72119, 72121, 72123, 72125, 72127) that correspond to the plurality of applications that operate within the messaging user interface of the messaging application. Activation of a respective toggle (e.g., 72118) causes a corresponding application to toggle between a hidden state and a revealed state in the messaging user interface of the messaging application (e.g., as shown in <figref idref="f0635">Figures 72S</figref>, <figref idref="f0646 f0647">72AD-72AE</figref>, and <figref idref="f0657">72AO</figref>).

1677Providing a first application-management interface 7270 that receives an input for initiating a process to uninstall at least a component of an installed application (e.g., as shown in <figref idref="f0637 f0638">Figures 72U-72V</figref>) and providing a second application-management interface 72116 that receives input for toggling between a hidden state and a revealed state of an installed application (e.g., as shown in <figref idref="f0646 f0647">Figures 72AD-72AE</figref>) provides the user with the ability to hide an application in the messaging user interface without deleting non-messaging components of the installed application. Providing the user with the ability to limit displayed components to those that the user intends to use makes the user-device interface more efficient (e.g., by reducing clutter in the interface), allowing the user to more efficiently locate an application-selection affordance for selection without entirely removing the access to non-messaging components of an application that corresponds to component that is hidden in the messaging user interface.

1678In some embodiments, the first application-configuration affordance 7226 (<figref idref="f0634">Figure 72R</figref>) is located (7416) in a fixed position relative to the plurality of application-selection affordances (e.g., 7228, 7230, and 7232) that correspond to the plurality of applications. In some embodiments, the first application-configuration affordance 7226 is always located at an end of a list of application-selection affordances (e.g., at the right end of a horizontal row of application-selection affordances).

1679Locating the first application-configuration affordance 7226 at a fixed position relative to the plurality of application-selection affordances allows the user to locate the application-configuration affordance 7226 quickly and consistently (e.g., because the user does not need to scroll back and forth among the plurality of application-selection affordances to locate the application configuration affordance). Reducing the number of inputs required and the time required for providing inputs to locate the application-configuration affordance makes the user-device interface more efficient.

1680In some embodiments, the device displays (7418), in the first application-management interface 7270, a search-input area 7290 (<figref idref="f0641">Figure 72Y</figref>); receives input for the search-input area (e.g., text input 7296 or voice input); and performs a search, using the input in the search-input area, for a plurality of applications that are operable within the messaging user interface (e.g., a search of applications available for installation for use in the messaging user interface 7200, a search of applications previously installed for use in the messaging user interface 7200, and/or a search of installed applications that have a revealed state (e.g., as indicated by the toggles (e.g., 72117, 72118, 72119, 72121, 72123, 72125, 72127) of application-management interface 72116). For example, in response to the search input received as shown in <figref idref="f0641">Figure 72Y</figref>, applications 72102 and 72014 are displayed as search results in <figref idref="f0642">Figure 72Z</figref>..

1681Displaying, in the first application-management interface 7270, a search-input area 7290 for performing a search for applications that are operable within the messaging user interface 7200, allows the user search for such applications without the need to navigate away from the messaging user interface 7200. As a result, the number of inputs required and the time required to locate applications that are operable within the messaging user interface 7200 is reduced, which makes the user-device interface more efficient.

1682In some embodiments, while displaying the second application-management interface, the device detects (7420) a fourth input (e.g., a tap input by a contact at a location indicated by focus selector 72122, <figref idref="f0646">Figure 72AD</figref>) at a location that corresponds to a first toggle (e.g., 72118, <figref idref="f0646">Figure 72AD</figref>) of the plurality of toggles. The first toggle 72118 corresponds to a second application, such as a stickers application (e.g., that is distinct from the first installed application) of the plurality of applications that operate within the messaging user interface 7200 of the messaging application. In response to detecting the fourth input, in accordance with a determination that a current state of the second application is a revealed state (e.g., as shown by the first state of first toggle 72118 in <figref idref="f0646">Figure 72AD</figref>), the device toggles the state of second application from the revealed state to the hidden state (e.g., as shown by the second state of first toggle 72118 in <figref idref="f0647">Figure 72AE</figref>). In accordance with a determination that the current state of the second application is a hidden state, the device toggles the second application from the hidden state to the revealed state. After toggling the first toggle 72118, the device redisplays the application-selection area 7224 that includes the plurality of scrollable application-selection affordances (e.g., in response to an input (e.g., at affordance 72130) to exit the second application-management interface 72116 followed by an input (e.g., at affordance 72134) to exit the first application-management interface 7270). In accordance with a determination that the second application is in the revealed state, the device displays a first application-selection affordance that corresponds to the second application in the redisplayed application-selection area, and in accordance with a determination that the second application is in the hidden state, the device foregoes displaying the first application-selection affordance that corresponds to the second application in the redisplayed application-selection area. For example, in response to the fourth input, the stickers application-selection affordance 7232 that was displayed in <figref idref="f0634">Figure 72R</figref> is no longer displayed in <figref idref="f0657">Figure 72AO</figref>.

1683Providing a second application-management interface that receives input for toggling between a hidden state and a revealed state of an installed application provides the user with the ability to hide an application in the messaging user interface without deleting the installed application entirely. This makes the user-device interface more efficient and enhances the operability of the device (e.g., the number of inputs required is reduced because the user does not need to provide the input required for uninstalling and/or reinstalling a device when hiding an application is sufficient for the user's needs).

1684In some embodiments, the device displays (7422), in the second application-management interface 72116, a plurality of arrangement indicia (examples of which are arrangement controls 72120 and 72131, Figure AF) that correspond to the plurality of applications that operate within the messaging user interface 7200 of the messaging application. The plurality of arrangement indicia include: a first arrangement indicator 72120 that corresponds to a third application (e.g. a tiny transit application, as indicated by application management listing 72110) that operates within the messaging interface (e.g., the third application is the same as or different from the second application (see 7314) that operates within the messaging interface), and a second arrangement indicator 72131 that corresponds to a fourth application (e.g., a reservations application, as indicated by application management listing 7278) that operates within the messaging interface 7200. While displaying the second application-management interface 72116, the device detects a fifth input that includes a movement of a contact on the touch-sensitive surface from a first location (e.g., a location indicated by focus selector 72124 in <figref idref="f0648 f0649">Figure 72AF</figref>) that corresponds to the first arrangement indicator 72120 (e.g., the movement of the contact drags the first arrangement indicator such that the first arrangement indicator moves in accordance with the movement of the contact). In response to detecting the fifth input, in accordance with a determination that movement of the contact on the touch-sensitive surface (e.g., as shown at <figref idref="f0650">Figures 72AF-72AG</figref>) meets rearrangement criteria, the device changes an order of the first arrangement indicator 72120 relative to the second arrangement indicator 72131 (e.g., the order is changed as shown at Figures AF-AJ). In some embodiments, rearrangement criteria include a distance criterion that is met when the movement of the contact increases above a threshold movement distance (e.g., in at least one direction, such as an upward direction or a downward direction.

1685Changing an order of the first arrangement indicator relative to the second arrangement indicator in a second application management interface that is distinct from an application area makes the user-device interface more efficient (e.g., by implementing rearrangement of application selection affordances in a location that is separate from the application area, reducing the likelihood of accidental triggering of a rearrangement mode while application selection affordances are displayed in the application area.

1686In some embodiments, after changing the order of the first arrangement indicator relative to the second arrangement indicator (e.g., as discussed with regard to 7422 and Figures AF-AJ), the device redisplays (7424) the application-selection area 7224 that includes the plurality of scrollable application-selection affordances (e.g., in response to an input (e.g., at affordance 72130) to exit the second application-management interface 72116 followed by an input (e.g., at affordance 72134) to exit the first application-management interface 7270). The device displays, in the redisplayed application-selection area 7224 (<figref idref="f0657">Figure 72AO</figref>) a second application-selection affordance 72126 of the plurality of scrollable application-selection affordances, wherein the second application-selection affordance 72126 corresponds to the third application that operates within the messaging interface 7200, and a third application-selection affordance 72128 of the plurality of scrollable application-selection affordances, wherein the third application-selection affordance 72128 corresponds to the fourth application that operates within the messaging user interface. An order of the second application-selection affordance 72126 relative to the third application-selection affordance 72128 corresponds to the order of the first arrangement indicator relative to the second arrangement indicator.

1687Changing an order of application-selection affordances in response to input for changing the order of a first arrangement indicator relative to a second arrangement indicator gives the user the ability to make the user-device interface more efficient (e.g., by rearranging application-selection affordances to place the most frequently used application-selection affordances within or proximate to a set of pre-selected set of initially displayed application-selection affordances).

1688It should be understood that the particular order in which the operations in <figref idref="f0789 f0792">Figures 74A-74D</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 7400 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 7400 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

1689The operations described above with reference to <figref idref="f0789 f0792">Figures 74A-74D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>. For example, one or more of the operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1690<figref idref="f0793 f0796">Figures 75A-75D</figref> are flow diagrams illustrating a method 7500 for translating message content in a messaging application, in accordance with some embodiments. The method 7500 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 7500 are, optionally, combined and/or the order of some operations is, optionally, changed.

1691The device displays (7502), on the display (e.g., touch screen 112) a messaging user interface 7200 (<figref idref="f0658">Figure 72AP</figref>). The messaging user interface includes a conversation transcript 7202 of a messaging session between a user of the electronic device and at least one other user.

1692The device (7504) receives a first message (e.g., a message displayed within message bubble 72140) within the messaging session from an electronic device that corresponds to another user included in the messaging session, wherein the first message includes foreign language text 72146 (e.g., text of a language that is different from one or more native languages indicated by one or more language settings of the device).

1693In response to receiving the first message, the device displays (7506) the first message 72140 in the conversation transcript 7202.

1694The device detects (7508) a first input at a first location (e.g., a location indicated by focus selector 72148 of <figref idref="f0658">Figure 72AP</figref> or a location indicated by focus selector 72154 of <figref idref="f0663">Figure 72AU</figref>) that corresponds to the foreign language text 72146 in the first message. For example, the device detects a gesture by a contact on the foreign language text 72146, in a message bubble 72140 in which the foreign language text 72146 is displayed, or proximate to a message bubble 72140 in which the foreign language text 72146 is displayed.

1695In response to detecting the first input at the first location that corresponds to the foreign language text 72146, in accordance with a determination that the first input meets translation criteria, the device displays (7510) a translation of the foreign language text (e.g., the device replaces display of the foreign language text 72146 with translated text 72150 as shown in <figref idref="f0659 f0660">Figures 72AQ-72R</figref>). In some embodiments, all of the foreign language text in the first message is translated. In some embodiments, a portion of the foreign language text in the first message is translated. In some embodiments, the foreign language text has a display characteristic (e.g., a font size, a font color, a font style, a font effect (such as highlighting, underlining, holding, capitalizing, and/or italicizing) and/or a background color) that is different from a display characteristic of native language text that is displayed in the conversation transcript (e.g., foreign language text 72146 is shown without boldface and translated text 72152 is shown with boldface, as shown in <figref idref="f0659 f0660">Figures 72AQ-72AR</figref>). In some embodiments, the foreign language text 72146 is replaced by translated foreign language text 72152. In some embodiments, the translation 72152 of the foreign language text is displayed alongside the foreign language text 72146. In accordance with a determination that the first input meets option-display criteria, the device displays a plurality of activatable indicia (e.g., a plurality of activatable indicia include one or more acknowledgement options and a translation option 72180 in an acknowledgement platter 72178 (<figref idref="f0685">Figure 72BQ</figref>) and/or a plurality of activatable indicia include one or more action items in a menu 72156 (<figref idref="f0673">Figure 72BE</figref>) that includes an option 72158 which, when activated, causes display of a translation of the foreign language text 72146. In some embodiments, in accordance with a determination that the first input does not meet the translation criteria and does not meet the option-display criteria, the electronic device continues to display the foreign language text 72146 in the first message (e.g., in message bubble 72140). This heuristic allows input at a location that corresponds to foreign language text to either cause a translated version of message text to be displayed (e.g., without having to find and activate a translation option in a menu) or to cause a plurality of activatable indicia to be displayed (e.g., to enable access to additional actions). This heuristic for input at a location that corresponds to foreign language text enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing for translation directly, as well as providing for other options) which, also reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

1696In some embodiments, the electronic device includes a touch-sensitive surface and one or more sensors configured to detect intensities of contacts with the touch-sensitive surface, and detecting the input at the first location that corresponds to the foreign language text includes (7512) detecting a contact on the touch-sensitive surface (e.g., a contact at a location indicated by focus selector 72148, <figref idref="f0658">Figure 72AP</figref>, or at a location indicated by focus selector 72154, <figref idref="f0663">Figure 72AU</figref>). The determination that the first input meets translation criteria includes a determination that the contact lifts off from the touch-sensitive surface before option-display criteria are met (e.g., the translation intensity criteria are met when a tap input is received, for example as shown in <figref idref="f0660 f0659">Figures 72AR-72AQ</figref>). The determination that the first input meets option-display criteria includes a determination that the characteristic intensity of the contact with the touch-sensitive surface meets option-display intensity criteria (e.g., the option-display intensity criteria are met when the characteristic intensity of the contact increases above a second intensity threshold, such as a light press intensity threshold level IT_L or a deep press intensity threshold IT_D), e.g., as shown in <figref idref="f0663 f0664">Figures 72AU-72AV</figref>.

1697Using contact intensity criteria at a location that corresponds to foreign language text to be used to either cause a translated version of a text message to be displayed (e.g., without having to find and activate a translation option in a menu) or cause a plurality of activatable indicia to be displayed (e.g., to enable access to additional actions) enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing for translation directly, as well as providing for other options).

1698In some embodiments, the electronic device includes a touch-sensitive surface and detecting the input at the first location that corresponds to the foreign language text includes (7514) detecting a contact on the touch-sensitive surface (e.g., a contact at a location indicated by focus selector 72186 in <figref idref="f0689">Figure 72BU-2</figref> or a contact at a location indicated by focus selector 72188 in <figref idref="f0689">Figure 72BV-2</figref>). The determination that the first input meets translation criteria includes a determination that the contact lifts off from the touch-sensitive surface before translation duration criteria are met (e.g., the input is a tap input, for example as shown in <figref idref="f0689">Figures 72BU-2 to 72BU-4</figref>.) The determination that the first input meets option-display criteria includes a determination that a duration of the contact on the touch-sensitive surface meets option display duration criteria (e.g., the option display duration criteria are met when the duration of the contact satisfies a duration threshold, such as a long press duration threshold, for example as shown in <figref idref="f0689">Figures 72BV-2 to 72BV-4</figref>).

1699Using contact duration criteria to either cause a translated version of a text message to be displayed (e.g., without having to find and activate a translation option in a menu) or cause a plurality of activatable indicia to be displayed (e.g., to enable access to additional actions) enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing for translation directly, as well as providing for other options).

1700In some embodiments, the electronic device includes a touch-sensitive surface 112 and one or more sensors configured to detect proximity of an input object 72192 above the touch-sensitive surface 112, and detecting the input at the first location that corresponds to the foreign language text includes (7516) detecting input (e.g., input at a location indicated by focus selector 72190, <figref idref="f0690">Figure 72BW</figref>) by the input object 72192. The determination that the first input meets translation criteria includes a determination that the input by the input object 72192 meets hover proximity criteria. For example, the hover proximity criteria are met when the input object 72192 is within a hover proximity range above the touch-sensitive surface 112 (e.g., the distance 72196 between input object 72192 and touch screen 112 decreases below a threshold hover distance, as shown in <figref idref="f0691">Figure 72BX</figref>), and the input object 72192 is not in contact with the touch-sensitive surface. In some embodiments, when the translation criteria include hover proximity criteria, the option-display criteria are met when the duration of a contact with the touch-sensitive surface exceeds a duration threshold (e.g., such as a tap threshold or a long press duration threshold), the characteristic intensity of the contact increases above a threshold intensity level (e.g., a light press intensity threshold IT_L or a deep press intensity threshold IT_D); or a contact with the touch-sensitive surface lifts off, subsequently touches down at the location that corresponds to the foreign language text, and then lifts off again within a duration of time that meets double-tap criteria.

1701In some embodiments, the determination that the first input meets translation criteria includes a determination (7518) that a focus selector (e.g., focus selector 72200, <figref idref="f0709">Figure 72CP</figref>) that corresponds to the first input moved to the first location that corresponds to the foreign language text 72146 from a second location that corresponds to another part of the foreign language text 72146 in the first message (e.g., focus selector 72200 moves from a first location as shown in <figref idref="f0709">Figure 72CP</figref> to a second location as shown in <figref idref="f0711">Figure 72CR</figref>). In some embodiments, the foreign language text between the first location and the second location is translated (e.g., less than all of the foreign language text 72146 in the first message is translated, as shown in <figref idref="f0712">Figure 72CS</figref>). In some embodiments, all of the foreign language text in the first message is translated. In some embodiments, all of a contiguous section of foreign language text (e.g., less than all of the foreign language text in the first message) at or proximate to the first location is translated. Translating text at locations that a finger (or other contact) moves over can help a user learn the foreign language text.

1702In some embodiments, displaying the translation of the foreign language text in accordance with the determination that the first input meets translation criteria includes displaying (7520) a translation of a first portion of the foreign language text (e.g., portion 72210 includes a single translated word that corresponds to portion 72208 of foreign language text 72146 as shown in <figref idref="f0715">Figure 72CV</figref>). While displaying the translation of the first portion 72210 of the foreign language text 72146, the device detects movement of a focus selector 72206 that corresponds to the first input (e.g., a pointer input, a contact with a touch sensitive surface, or an input by an input object that meets hover proximity criteria) to a second location (e.g., as shown by focus selector 72206 in <figref idref="f0717">Figure 72CX</figref>) that corresponds to another part of the foreign language text. In response to detecting the movement of the focus selector to the second location, the device displays a translation of a second portion of the foreign language text (e.g., portion 72210 includes multiple translated words that correspond to portion 72208 of foreign language text 72146, as shown in <figref idref="f0717">Figure 72CX</figref>). In some embodiments, the second portion includes the first portion (e.g., the translation of the foreign language text is gradually revealed as the input moves). In some embodiments, the second portion is distinct from the first portion (e.g., a portion of the translated foreign language text is temporarily revealed as the input moves).

1703Progressively revealing translated text in a message in response to movement of a focus selector allows a translation of a portion of foreign language text to be displayed while leaving a portion of the foreign language text untranslated if desired. Displaying the translation in this manner enhances the privacy provided by the device (e.g., by continuing to display an untranslated version of a portion of the foreign language text, which provides security when the foreign language text cannot be read by other people in the vicinity of the device.

1704In some embodiments, the device receives (7522) a second message (e.g., a message displayed within message bubble 72142) within the messaging session. In accordance with a determination that the second message includes foreign language text and in accordance with a determination that the option-display criteria are met, the device displays, in a plurality of activatable indicia, an activatable indicator which, when activated, causes display of a translation of the foreign language text in the second message (e.g., as described with regard to 7510 and option 72158 of <figref idref="f0673">Figure 72BE</figref>). In accordance with a determination that the second message does not include foreign language text and in accordance with a determination that the option-display criteria are met, the device displays a plurality of activatable indicia, without displaying the activatable indicator (e.g., as shown in <figref idref="f0678">Figure 72BJ</figref>). In some embodiments, the electronic device determines whether a received message includes foreign language text. In some embodiments, a device that is remote from the electronic device (e.g., a server that supports messaging functions) determines whether the received message includes foreign language text.

1705Automatically including an activatable indicator for displaying translated foreign language text in a displayed plurality of activatable indicia (e.g., a menu or an acknowledgements platter) provides an additional control option for translation without consuming space among the plurality of activatable indicia when the translation option is not needed. This heuristic enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing display space consumed by the plurality of activatable indicia and eliminating unintended selection of a translation control when no foreign language text is present in a message.)

1706In some embodiments, while displaying the translation 72150 of the foreign language text (e.g., as shown in <figref idref="f0721">Figure 72DB</figref>), the device determines (7526) whether the translation of the foreign language text meets translation-display-cessation criteria (e.g., determining whether a characteristic intensity of the contact in the first input decreases below an first intensity threshold level (such as light press intensity threshold level IT_L) without increasing above a second intensity threshold level (such as deep press intensity threshold level IT_D) before liftoff of the contact from the touch sensitive surface, determining whether an amount of time since the translated foreign language text was displayed exceeds a threshold time limit, and/or determining whether a contact in the first input has lifted off from the touch sensitive surface). In accordance with a determination that the displayed translation of the foreign language text meets the translation-display-cessation criteria (e.g., as shown in <figref idref="f0721 f0722">Figures 72DB-72DC</figref>), the device ceases to display the translation of the foreign language text and re-displaying the corresponding foreign language text. In accordance with a determination that the displayed translation of the foreign language text does not meet the translation-display-cessation criteria, the device continues to display the translation of the foreign language text (e.g., as shown in Figures DE-DI).

1707In some embodiments, translated foreign language text is displayed in response to an input by a contact that meets characteristic intensity criteria and/or contact duration criteria, and the translated foreign language text ceases to be displayed when the contact lifts off of the touch-sensitive surface. For example, when translation of messages is used for language learning, a user may wish to redisplay an untranslated version of the foreign language text to facilitate learning the connection between the translated and untranslated text.

1708In some embodiments, the one or more activatable indicia include an option to display the translated foreign language text for a predefined duration of time. In some embodiments, in accordance with a determination that the option to display the translated foreign language text for a predefined duration of time is selected, the translated foreign language text is displayed, and after the predefined duration of time, the translated foreign language text reverts to untranslated foreign language text.

1709Automatically re-displaying the foreign language text when translation-display-cessation criteria are met allows the untranslated foreign language text to be re-displayed without requiring further user input following the input that displayed the translation. Automatically re-displaying untranslated foreign language text without requiring additional user input makes the user-device interface more efficient by reducing the number of inputs required to operate the device.}

1710In some embodiments, while displaying the translation 72146 of the foreign language text, the device detects (7526) a second input (e.g., by a contact at a location indicated by focus selector 72148, as shown in <figref idref="f0661">Figure 72AS</figref>) at a third location that corresponds to the translation 72150 of the foreign language text (e.g., a location that is the same as the first location, the same as the second location, or distinct from the first location and the second location). In response to detecting the second input at the third location that corresponds to the translated foreign language text 72150, in accordance with a determination that the second input meets re-display criteria, the device ceases to display the translation 72150 of the foreign language text and re-displays the corresponding foreign language text 72146 (e.g., as shown in <figref idref="f0661 f0662">Figures 72AS-72AT</figref>, . In some embodiments, the same type of input used for displaying the translation of the foreign language text is used to re-display the original, untranslated foreign language text. In some embodiments, displaying the translation of the foreign language text is irreversible.

1711In some embodiments, while displaying the translation of the foreign language text, the device detects (7528) a third input at a fourth location (e.g., a location indicated by focus selector 72164 of <figref idref="f0671">Figure 72BC</figref>) that corresponds to the translation 72150 of the foreign language text (e.g., a location that is the same as the first location, the same as the second location, the same as the third location, or distinct from the first, second, and third locations). In response to detecting the third input at the fourth location that corresponds to the translation 72150 of the foreign language text, in accordance with a determination that the third input meets the option-display criteria, displaying a plurality of activatable indicia (e.g., the action items displayed in menu 72156), wherein the plurality of activatable indicia include an activatable indicator 72158 which, when activated, causes re-display of the original, un-translated foreign language text 72146 (e.g., as shown in <figref idref="f0670 f0674">Figures 72BB-72BF</figref>.

1712Displaying an activatable indicator for re-displaying the foreign language text in response to user input allows the un-translated foreign language text to be re-displayed with controls that are displayed as needed, without ongoing display of additional controls for undoing a previously performed translation. This enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing added functionality to a messaging user interface without reducing space available to display message content in the messaging user interface).

1713It should be understood that the particular order in which the operations in <figref idref="f0793 f0796">Figures 75A-75D</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 7500 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 7500 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

1714The operations described above with reference to <figref idref="f0793 f0796">Figures 75A-75D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>. For example, one or more of the operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.

1715<figref idref="f0797 f0799">Figures 76A-76C</figref> are flow diagrams illustrating a method 7600 for translating message content in a messaging application, in accordance with some embodiments. The method 7600 is performed at an electronic device (e.g., device 300, <figref idref="f0004">Figure 3</figref>, or portable multifunction device 100, <figref idref="f0001">Figure 1A</figref>) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 7600 are, optionally, combined and/or the order of some operations is, optionally, changed.

1716The device displays (7602), by a display (e.g., touch screen 112), a messaging user interface 7200 (<figref idref="f0658">Figure 72AP</figref>) on the display. The messaging user interface includes a conversation transcript 7202 of a messaging session between a user of the electronic device and at least one other user.

1717The device receives (7604) a first message (e.g., a message displayed within message bubble 72140) within the messaging session from an electronic device that corresponds to another user included in the messaging session, wherein the first message includes foreign language text 72146 (e.g., text of a language that is different from one or more native languages indicated by one or more language settings of the device).

1718In response to receiving the first message, the device displays (7606) the first message 72140 in the conversation transcript 7202.

1719The device detects (7608) a first input at a location (e.g., a location indicated by focus selector 72148 of <figref idref="f0658">Figure 72AP</figref> or a location indicated by focus selector 72154 of <figref idref="f0663">Figure 72AU</figref>) that corresponds to the foreign language text 72146 in the first message. For example, the device detects a gesture by a contact on the foreign language text 72146, in a message bubble 72140 in which the foreign language text 72146 is displayed, or proximate to a message bubble 72140 in which the foreign language text 72146 is displayed.

1720In response to detecting the first input at the location that corresponds to the foreign language text 72146, in accordance with a determination that the first input meets translation criteria, the device performs (7610) a foreign-language-text-translation action (e.g., displaying a menu 72156 (<figref idref="f0673">Figure 72BE</figref>) or platter 72178 (<figref idref="f0685">Figure 72BQ</figref>) that includes an activatable option (e.g., option 72158 of menu 72156 or option 72180 of platter 72178) to translate the foreign language text, translating the foreign language text 72146, and/or displaying the translation 72150 of the foreign language text). In accordance with a determination that the first input does not meet the translation criteria, the device forgoes performance of the foreign-language-text-translation action.

1721Translating and/or displaying foreign language text in response to user input received at a location that corresponds to foreign language text in a received message allows translated text to be displayed without displaying additional controls for obtaining the translation. Providing an activatable option to translate foreign language text without ongoing display of additional controls for translation enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing added functionality to a messaging user interface without constantly reducing the space available to display message content in the messaging user interface), which also reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

1722In some embodiments, the electronic device includes (7612) a touch-sensitive surface 112 and one or more sensors configured to detect intensities of contacts with the touch-sensitive surface 112. In some embodiments, detecting the first input at the first location (e.g., a location indicated by focus selector 72190, <figref idref="f0722">Figure 72DC</figref>) that corresponds to the foreign language text 72146 includes detecting a contact on the touch-sensitive surface. In accordance with a determination that the first input meets temporary-translation-display criteria (e.g., criteria that are met when a characteristic intensity of the contact in the first input decreases below an first intensity threshold level (such as light press intensity threshold level IT_L) without increasing above a second intensity threshold level (such as deep press intensity threshold level IT_D) before liftoff of the contact from the touch sensitive surface) performing the foreign-language-text-translation action includes temporarily displaying a translation of the foreign language text (e.g., as shown in <figref idref="f0720 f0722">Figures 72DA-72DC</figref>). In some embodiments, when temporary-translation-display criteria are met, the translated foreign language text 72150 is displayed temporarily (e.g., for a predetermined amount of time, until a subsequent input meeting foreign language text re-display criteria is received, or until a contact lifts off) after which the original, un-translated foreign language text 72146 is re-displayed.

1723In some embodiments, in accordance with a determination that the first input meets fixed-translation-display criteria, performing the foreign-language-text-translation action includes (7614) fixedly replacing display of the foreign language text 72146 with the translation 72150 of the foreign language text (e.g., as shown at <figref idref="f0723 f0728">Figures 72DD-72DI</figref>). In some embodiments, the translated foreign language text is displayed fixedly (e.g., for the subsequent time during which the first message is displayed in the messaging session). In some embodiments, contact intensity criteria are used to determine whether the input meets temporary-translation-display criteria and the translation is displayed temporarily, or whether the input meets fixed-translation-display criteria and the translation is displayed fixedly. For example, the translation is displayed temporarily in response to a light press (e.g., as shown at <figref idref="f0718 f0723">Figures 72CY-72DD</figref>) and the translation is displayed fixedly in response to a deep press (e.g., as shown at <figref idref="f0723 f0728">Figures 72DD-72DI</figref>), or vice versa.

1724Using contact intensity criteria to determine whether to temporarily or fixedly display a translation of foreign language text in a message allows a single input by a contact to be used for either temporary display or fixed display of a translation. Enabling multiple possible operations in response to a single input by a contact enhances the operability of the device and makes the user-device interface more efficient, which also reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

1725In some embodiments, the determination that the first input meets the fixed-translation-display criteria includes (7616) a determination that a characteristic intensity of the contact on the touch-sensitive surface meets fixed translation intensity criteria (e.g., as described with regard to <figref idref="f0723 f0728">Figures 72DD-72DI</figref>). In some embodiments, the fixed translation intensity criteria are met when the characteristic intensity of the contact increases above a second intensity threshold, such as a deep press intensity threshold IT_D.

1726In some embodiments, the determination that the first input meets the fixed-translation-display criteria includes (7618) a determination that the duration of the contact on the touch-sensitive surface meets fixed translation duration criteria. In some embodiments, the fixed translation duration criteria are met when the duration of the contact increases above a time threshold, such as a long press duration threshold.

1727In some embodiments, performing the foreign-language-text-translation action includes (7620): displaying a translation 72150 of the foreign language text; determining whether lift-off of the contact from the touch-sensitive surface has occurred; and, in response to detecting lift-off of the contact from the touch-sensitive surface, ceasing to display the translation 72150 of the foreign language text (and, in some embodiments, re-displaying foreign language text 72146).

1728Ceasing to display translated foreign language text in response to detecting lift-off of the contact from the touch-sensitive surface provides an additional control option without cluttering the messaging user interface with additional displayed controls. Providing additional control options without cluttering the messaging UI enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing added functionality to a messaging user interface without reducing space available to display message content in the messaging user interface.)

1729In some embodiments, performing the foreign-language-text-translation action includes displaying (7622), over the conversation transcript, (e.g., in a location that corresponds to the displayed first message, such as partially overlaying the first message or proximate to the first message) a platter 72178 (<figref idref="f0685">Figure 72BQ</figref>) that includes a plurality of activatable indicia (e.g., an acknowledgement options menu for responding to a received message, with options such as a heart, thumbs up, and thumbs down), wherein the plurality of activatable indicia includes a translation indicator 72180 which, when activated, causes display of a translation for at least a portion of the foreign language text.

1730Displaying an activatable indicator for translating at least a portion of the foreign language text in response to user input allows translated foreign language text to be displayed with controls that are displayed as needed, without ongoing display of additional controls for performing a translation. Providing an activatable option to translate foreign language text without ongoing display of additional controls for translation enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing added functionality to a messaging user interface without constantly reducing space available to display message content in the messaging user interface).}

1731In some embodiments, the electronic device includes (7624) a touch-sensitive surface 112 and one or more sensors configured to detect proximity of an input object 72192 above the touch-sensitive surface 112 (e.g., as shown in <figref idref="f0691">Figures 72BW-72BX</figref>), detecting the input at the first location (e.g., a location indicated by focus selector 72190) that corresponds to the foreign language text 72146 includes detecting input by the input object 72192; and the determination that the first input meets translation criteria includes a determination that the input by the input object meets hover proximity criteria (e.g., the distance between 72192 and touch screen 112 decreases below the threshold hover distance, as shown in <figref idref="f0691">Figure 72BX</figref>). In some embodiments, the hover proximity criteria are met when the input object is within a threshold hover distance above the touch-sensitive surface and is not in contact with the touch-sensitive surface 112.

1732In some embodiments, the determination that the first input meets translation criteria includes (7626) a determination that a focus selector (e.g., focus selector 72200, <figref idref="f0709">Figure 72CP</figref>) that corresponds to the first input moved to the first location that corresponds to the foreign language text 72146 from a second location that corresponds to another part of the foreign language text 72146 (e.g., focus selector 72200 moves from a first location as shown in <figref idref="f0709">Figure 72CP</figref> to a second location as shown in <figref idref="f0711">Figure 72CR</figref>). In some embodiments, the foreign language text between the first location and the second location is translated (e.g., less than all of the foreign language text in the first message is translated). In some embodiments, all of the foreign language text in the first message is translated. In some embodiments, all of a contiguous section of foreign language text (e.g., less than all of the foreign language text in the first message) at or proximate to the first location is translated. Translating text at locations that a finger (or other contact) moves over can help a user learn the foreign language text.

1733In some embodiments, displaying the translation of the foreign language text in accordance with the determination that the first input meets translation criteria includes displaying (7628) a translation of a first portion of the foreign language text (e.g., portion 72210 includes a single translated word that corresponds to portion 72208 of foreign language text 72146 as shown in <figref idref="f0715">Figure 72CV</figref>). While displaying the translation of the first portion 72210 of the foreign language text 72146, the device detects (7628) movement of a focus selector 72206 that corresponds to the first input (e.g., a pointer input, a contact with a touch sensitive surface, or an input by an input object that meets hover proximity criteria) to a second location (e.g., as shown by focus selector 72206 in <figref idref="f0717">Figure 72CX</figref>) that corresponds to another part of the foreign language text. In response to detecting the movement of the focus selector to the second location, the device displays a translation of a second portion of the foreign language text (e.g., portion 72210 includes multiple translated words that correspond to portion 72208 of foreign language text 72146, as shown in <figref idref="f0717">Figure 72CX</figref>). In some embodiments, the second portion includes the first portion (e.g., the translation of the foreign language text is gradually revealed as the input moves). In some embodiments, the second portion is distinct from the first portion (e.g., the translated foreign language text is temporarily revealed as the input moves).

1734Progressively revealing translated text in a message in response to movement of a focus selector allows a translation of a portion of foreign language text to be displayed while leaving a portion of the foreign language text untranslated if desired. Displaying the translation in this manner enhances the privacy provided by the device (e.g., by continuing to display an untranslated version of a portion of the foreign language text, which provides security when the foreign language text cannot be read by other people in the vicinity of the device.)

1735It should be understood that the particular order in which the operations in <figref idref="f0797 f0799">Figures 76A-76C</figref> have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein are also applicable in an analogous manner to method 7600 described above. For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described above with reference to method 7600 optionally have one or more of the characteristics of the contacts, gestures, user interface objects, intensity thresholds, focus selectors, and animations described herein with reference to other methods described herein. For brevity, these details are not repeated here.

1736The operations described above with reference to <figref idref="f0797 f0799">Figures 76A-76D</figref> are, optionally, implemented by components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>. For example, one or more of the operations are optionally implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in <figref idref="f0001 f0002">Figures 1A-1B</figref>.
