Device and method for dynamically changing information provided on a standby screen of a cellular telephone

FIELD OF THE INVENTION

0001The present invention relates to cellular telephones, and more particularly, to cellular telephones including user interfaces and related methods of displaying information on such user interfaces.

BACKGROUND OF THE INVENTION

0002The vast majority of state-of-the-art cellular telephones include at least one display screen. Most state-of-the-art cellular telephones also include a plurality of applications such as, for example, games, appointment book applications, address books, call history logs, cameras, photo galleries, and the like. Typically, the display screen is used to access and operate these applications. The display screen also typically displays information when a conventional cellular telephone is used to make or receive a telephone call, such as the dialed or incoming telephone number, the connection status, the length of the call, etc.

0003When a conventional cellular telephone is in a "standby mode", its display screen will typically either be blank or will display a "standby screen." Herein, the term "standby mode" refers to a mode of the cellular telephone where the cellular telephone does not have an active ongoing telephone call connection and where a user of the cellular telephone is not actively running other applications that require user input such as games, calendar applications, address book applications, message retrieval, photo viewing and the like. The term "standby screen" refers to the information that is displayed on the display screen of the cellular telephone while the telephone is in the standby mode. While the information provided on the standby screen of a conventional cellular telephone may differ depending upon the manufacturer/model of the telephone and/or the cellular service provider, typically the information displayed includes the time of day, an icon indicating the signal strength of a signal received from a cellular base station, an icon indicating the remaining battery power, and perhaps the name of the cellular service provider. The standby screen may also include, for example, menu access points, other indicia regarding the options currently set on the cellular telephone (e.g., volume level, mute function, etc.) and/or additional information regarding the services that are currently available from the cellular service provider (e.g., current availability of data transmission and reception services). A user of the cellular telephone may also often adjust the background picture provided on the standby screen by selecting from a variety of options or by selecting a photograph that replaces a pre-set background picture or pattern.

0004<figref idref="f0001"><b>Figure 1A</b></figref> depicts a standby screen <b>20</b> that may be displayed on a display screen <b>15</b> of an exemplary conventional cellular telephone <b>10.</b> As shown in <figref idref="f0001 f0002"><b>Figure 1</b></figref><b>,</b> the standby screen <b>20</b> of cellular telephone <b>10</b> may include a signal strength indicator <b>30,</b> a remaining battery power indicator <b>32,</b> a GPRS availability indicator <b>34,</b> the name <b>36</b> of the cellular service provider that operates the cellular base station to which the cellular telephone is currently assigned, the date <b>38</b> and the current time <b>40.</b> Several labels <b>44</b> may also be provided that indicate menus that can be opened by pressing corresponding soft keys that are located under respective of the labels <b>44</b> on a keypad of cellular telephone <b>10.</b>

0005When an unread message (e.g., voice mail, e-mail, text message, etc.) is available and/or a call has been received that the user did not answer, the standby screen <b>20</b> may be updated to include an icon or message window notifying the user of the availability of the message or the telephone number of the missed call. <figref idref="f0002"><b>Figure 1B</b></figref> shows such an updated standby screen <b>20</b> that includes an unread message indicator <b>46</b> and a window <b>48</b> with a message notifying the user that a message has been received.

0006Methods for updating standby screens on cellular telephones are know. in particular, <patcit id="pcit0001" dnum="WO02052815A2A"><text>PCT Patent Application Publication No. WO 02/052815 A2</text></patcit> discloses methods for updating an idle screen of a mobile telephone with information of a kind or from a source selected by a user. Moreover, methods of automatically displaying data supplied from a remote service provider to a wireless device for display in a separate application that is running on the wireless device are also known. For example, <patcit id="pcit0002" dnum="WO03075547A2A"><text>PCT Patent Application Publication No. WO 03/075547 A2</text></patcit> discloses methods for displaying data such as, for example, weather data, within another application such as, for example, a calendar application, that is running on a cellular telephone.

Finally, <patcit id="pcit0004" dnum="US20040266458A1"><text>U.S. Patent Publication No. 2004/0266458 A1</text></patcit> discloses a mobile communications unit that includes the various conventional components of a cellular telephone.

SUMMARY

0007Pursuant to embodiments of the present invention, methods of displaying information on a display of a cellular telephone are provided. Pursuant to these methods, information from at least a first of a plurality of applications is displayed on the display while the cellular telephone is in a standby mode. Then, a second of the plurality of applications is automatically selected based on a set of pre-defined rules, and the displayed information from the first of the plurality of applications is thereafter automatically replaced with information from the second of the plurality of applications while the cellular telephone remains in the standby mode. In some embodiments, the method may also involve displaying information from a third of the plurality of applications in response to a received command.

0008In some embodiments, the second of the plurality of applications is automatically selected based on at least one of a time of day, a day of the week, a location of the cellular telephone and/or a location of another cellular telephone. In those and/or other embodiments, the set of pre-defined rules may include a rule that selects the second of the plurality of applications based at least in part on (1) a temporal parameter, (2) a location of the cellular telephone and/or (3) a location of the cellular telephone relative to another location. In still other embodiments, the second of the plurality of applications may be automatically selected based on a determination that at least two different criteria have been satisfied such as, for example, a temporal criterion and/or location criterion. At least some of the set of pre-defined rules may be pre-programmed into the cellular telephone. A user of the cellular telephone may also and/or alternatively provide parameters that are used to establish at least some of the set of pre-defined rules. At least some of the above-described methods may be carried out by a computer program product that is stored in a memory of the cellular telephone.

0009Pursuant to further embodiments of the present invention, methods of displaying information on a display associated with a cellular telephone are provided in which information from at least a first of a plurality of applications is displayed on the display while the cellular telephone is in a standby mode. Then, a second of the plurality of applications is automatically selected based on at least one of a temporal parameter and/or a location of the cellular telephone. Thereafter, information from the second of the plurality of applications is automatically displayed while the cellular telephone remains in the standby mode. The information from the second of the plurality of applications may comprise, for example, weather-related information or traffic-related information. The method may also involve providing an audible or vibrating notification that the displayed information from the first of the plurality of applications has been replaced with information from the second of the plurality of applications. In these methods, the display may be part of the cellular telephone or may be a display on a device separate from the cellular telephone that receives information from the cellular telephone via a wireless communications link.

0022Pursuant to embodiments of the present invention, cellular telephones are provided that have enhanced standby screens that provide more useful information to a user of the cellular telephone. Methods of operating cellular telephones are also provided that may be used to dynamically control the information that is included on the standby screen. The cellular telephones and methods of operating such devices according to embodiments of the present invention may be used to provide information, at the right time, and in the right context, to a user of the cellular telephone. This information may be conveniently displayed on the standby screen of the cellular telephone, which is the screen of the user interface that most cellular telephone user's may view most often.

0023In some embodiments of the present invention, the cellular telephone may include a plurality of "standby screen" applications. A "standby screen application" is an application that generates information that may be displayed on a display of the cellular telephone while the cellular telephone is in the standby mode. Some or all of the plurality of standby screen applications are kept running while the cellular telephone is in the standby mode. Information provided by selected of the standby screen applications is then included on a standby screen of the cellular telephone.

0024Most or all of the standby screen applications may comprise "widgets." A "widget" refers to a small, self-contained application that has its own behavior and functionality that provides the user of the cellular telephone with "at-a-glance" information. By "at-a-glance" information it is meant that the user of the cellular telephone need only look at the displayed standby screen to obtain the information without, for example, having to traverse a menu, select an option, push a button, etc. Examples of the information that might be provided by widgets according to embodiments of the present invention are current weather conditions, weather forecasts, traffic updates, appointment summaries, task lists and the like.

0025The standby screen applications may provide valuable information to a user without requiring much effort on the part of the user to obtain this information. However, there are challenges involved in implementing these applications on a mobile cellular telephone. The first such challenge is the screen size of the display(s) provided on most cellular telephones. Typically, cellular telephone display screens have a diagonal measurement of between about one to about three inches (although both smaller and larger display screens are provided on certain models). Thus, the area of the display screen may range from less than one to perhaps four or five square inches (and perhaps 7-10 square inches on personal digital assistant style cellular telephones). This small display screen size limits both the amount of information that may be presented from any one standby screen application at a given time, as well as the number of standby screen applications that may simultaneously display information to a user.

0026A second challenge associated with getting the most out of standby screen applications in a mobile cellular telephone context is that many users carry their cellular telephones with them during most waking hours, seven days a week. As such, the type of information that may be of value to a user tends to change over time. Thus, in the cellular telephone context, it may be more of a challenge to consistently provide the user with information that is relevant to the user's current activities, as the activities may change more often than, for example, the activities that the user is engaged in while in front of their computer at work.

0027Thus, according to certain embodiments of the present invention, cellular telephones (and related methods) are provided in which the information from the standby screen application(s) that is displayed is automatically (i.e., without user input or intervention) changes according to specific parameters such as the time of day, the day of the week, the location of the user, the presence of other individuals, etc. Typically, information from only one or a few of the standby screen applications will be displayed on the standby screen at any given time. The cellular telephone, however, will sense when different pre-defined criteria have been met and then automatically replace the information included on the standby screen from one or more standby screen applications with information from one or more different standby screen applications in order to provide the user with information that is most likely to be relevant at any given time.

0028<figref idref="f0003"><b>Figure 2</b></figref> is a block diagram of a cellular telephone <b>100</b> according to certain embodiments of the present invention. As shown in <figref idref="f0003"><b>Figure 2</b></figref><b>,</b> the cellular telephone <b>100</b> includes a controller <b>110,</b> which may comprise, for example, a microprocessor, a microcontroller or a similar data processing device that executes program instructions stored, for example, in a memory <b>120</b> of the cellular telephone <b>100.</b> The memory <b>120</b> may comprise, for example, a non-volatile memory such as a flash memory, a dynamic random access memory (DRAM), an electrically erasable programmable read only memory (EEPROM), a read only memory or any other memory or storage device or combination of memory storage devices. The controller <b>110</b> is operatively associated with user interface components such as, for example, a keypad <b>140,</b> a speaker <b>142,</b> a microphone <b>144</b> and a display <b>146,</b> operations of which are known to those of skill in the art and will not be further discussed herein. The controller <b>110</b> also controls and/or monitors operations of a radio transmitter <b>150</b> and a receiver <b>160</b> (which collectively are referred to herein as a transceiver) that may respectively transmit and receive radio frequency (RF) signals over a communications medium via an antenna <b>170.</b> The cellular telephone <b>100</b> may be associated with a user <b>180</b> who owns and/or uses the cellular telephone <b>100.</b>

0029As shown in <figref idref="f0003"><b>Figure 2</b></figref><b>,</b> the memory <b>120</b> may include a plurality of applications <b>126</b> that are typical of the applications provided on conventional cellular telephones. Such applications may include, for example, an address book application, a message box application, games, a digital camera application, an internet browser application, control setting applications, call listing applications, etc. One or more of the applications <b>126</b> may control operations of the cellular telephone <b>100.</b> The applications <b>126</b> will not be described further herein as the operations thereof are generally well understood in the art.

0030As is further shown in <figref idref="f0003"><b>Figure 2</b></figref><b>,</b> the memory <b>120</b> may also include a plurality of standby screen applications <b>122</b> that may be executed by the controller <b>110</b> when the cellular telephone <b>100</b> is in the standby mode. Typically, each of the plurality of standby screen applications <b>122</b> will comprise a stand alone, separately executable application. However, it will be appreciated that one or more of the plurality of standby screen applications <b>122</b> may be implemented as a single, more complex application, that implements the functionality of what would otherwise be two or more stand-alone standby screen applications <b>122.</b> Herein, where the functionality of two or more of the standby screen applications <b>122</b> are combined into a single application, the single application may be considered to be a "plurality" of standby screen applications <b>122</b> as the single application implements the functionality of multiple of the standby screen applications <b>122.</b>

0031As is also shown in <figref idref="f0003"><b>Figure 2</b></figref><b>,</b> the memory <b>120</b> may also include a standby screen control application <b>124.</b> The standby screen control application <b>124</b> may control what information provided by the various standby screen applications <b>122</b> is displayed on the standby screen at any given time. In certain embodiments of the present invention, the standby screen control application <b>124</b> may include a plurality of pre-defined rules that are followed to determine the information that is displayed on the standby screen. As will be discussed in more detail herein, these pre-defined rules may be standard rules and/or customized rules where a user <b>180</b> of the cellular telephone <b>100</b> helps define the rules that select when and what information is displayed on the standby screen.

0032The standby screen applications <b>122</b> may include any of a wide variety of applications. As noted above, many or all of these applications may comprise widgets that provide the user <b>180</b> with "at-a-glance" information. In certain embodiments of the present invention, one of the standby screen applications <b>122</b> may comprise a current weather widget <b>130</b> that generates current weather information such as, for example, the current temperature, the wind speed, the wind direction, the relative humidity, the current wind chill reading, the current barometric pressure and direction of change of the barometric pressure and/or the current overall weather condition (e.g., sunny, partly cloudy, raining, snow, etc.). Some or all of this current weather information may be consolidated into an easy to read graphical display that may be included on a portion of the standby screen, such as, for example, the graphical display <b>200</b> illustrated in <figref idref="f0004"><b>Figure 3A</b></figref><b>.</b> As shown in <figref idref="f0004"><b>Figure 3A</b></figref><b>,</b> the exemplary graphical display <b>200</b> includes a display of the current temperature <b>202,</b> a display of the current windspeed and direction <b>204,</b> and a display of the current weather conditions <b>206.</b> The graphical display <b>200</b> primarily uses graphical icons to summarize the current weather information in an easy to read fashion. The current weather widget <b>130</b> may, for example, obtain the current weather information over the cellular network and/or by accessing publicly available information on, for example, the Internet. It will be appreciated that the same current weather information may be provided for everyone in a general area (e.g., a metropolitan area) or, alternatively, location information associated with the cellular telephone <b>100</b> may be obtained and the current conditions measured at a weather monitoring station that is closest to the current location of the cellular telephone <b>100</b> may be accessed to obtain the current weather information provided by current weather widget <b>130.</b>

0033The standby screen applications <b>122</b> may also include a traffic widget <b>132</b> that displays traffic information that may be relevant to the user <b>180</b> of the cellular telephone <b>100.</b> The traffic information may be consolidated into an easy-to-read graphical summary that is displayed on a portion of the standby screen such as, for example, the exemplary traffic summary <b>210</b> illustrated in <figref idref="f0004"><b>Figure 3B</b></figref><b>.</b> As shown in <figref idref="f0004"><b>Figure 3B</b></figref>, in this particular embodiment, the traffic summary <b>210</b> may include a linear scale <b>212</b> that corresponds to the intensity of the traffic, and an indicator <b>214</b>, that shows the current traffic intensity relative to the linear scale <b>212.</b> The traffic summary <b>210</b> may also include, for example, further information <b>216</b> regarding the current traffic conditions and/or an indication <b>218</b> of the region for which the traffic summary applies. In other embodiments (which are not depicted in <figref idref="f0004"><b>Figure 3B</b></figref>), the traffic widget <b>132</b> may generate a traffic summary which displays a map of an area of interest to the user <b>180</b> (e.g., the route from the user's home to the user's office) with areas where traffic incidents (accidents, stalled cars, etc.) have occurred and/or where points of congestion currently exist highlighted on the map.

0034As another example, the standby screen applications <b>122</b> may also include a calendar widget <b>134</b> that displays information from an appointment book application <b>126</b> that is provided on the cellular telephone <b>100.</b> The calendar widget <b>134</b> may comprise a stand alone widget or may be implemented as part of, for example, the appointment book or calendar application <b>126.</b> As shown in <figref idref="f0004"><b>Figure 3C</b></figref><b>,</b> the calendar widget <b>134</b> may display on a portion of the standby screen a listing <b>220</b> of upcoming appointments. This listing <b>220</b> may be a succinct listing that provides "at-a-glance" information to the user <b>180.</b> The standby screen applications <b>122</b> may also include a task widget <b>136</b> that displays information from a task list application <b>126</b> that is provided on the cellular telephone <b>100.</b>

0035Another example of a standby screen application <b>122</b> according to certain embodiments of the present invention is a message widget <b>138.</b> The message widget <b>138</b> may, for example, display in a window on the standby screen the sending party name, message title and date and/or time received of unread messages such as e-mail, text and/or SMS messages. In some embodiments, the message widget <b>138</b> may display information for only the last received message. In other embodiments, the message widget <b>138</b> may display information for multiple messages such as, for example, the last five (or some other number) of received, but unread messages. The message <b>widget 138</b> may be configured to display the above-discussed information for a predetermined time after receipt of a message (e.g., 5 minutes), until the user <b>180</b> actively clears the display (e.g., by tapping on a close display icon) and/or until the pre-defined rules are satisfied such that information from another of the standby screen applications <b>122</b> replaces the information provided by the message widget <b>138.</b>

0036In certain embodiments of the present invention, the cellular telephone <b>100</b> may automatically notify the user <b>180</b> when the information displayed on the standby screen changes. In some embodiments, this notification may comprise an audible alert (which the user <b>180</b> may customize in terms of both the sound and volume) or activation of a vibration device included in the cellular telephone <b>100.</b> This notification may be provided each time the information displayed on the standby screen changes, or only when certain information is added to the display screen (e.g., information provided by a presence widget). The notification may also only be provided during selected hours of the day (e.g., the notification function may be turned off from 10:00 pm until 7:00 am each day). This notification feature may be used, for example, with the message widget <b>138</b> to notify the user <b>180</b> that information regarding a recently received message is displayed on the standby screen. In some embodiments of the present invention, a notification is provided at least some of the time after a message is received, and the information provided by the message widget <b>138</b> is displayed for a pre-selected amount of time and then replaced with other information.

0037In some embodiments of the present invention, the user <b>180</b> of the cellular telephone <b>100</b> may help customize operation of the standby screen control application <b>124</b> in order to increase the relevance and/or usefulness of the information displayed on the standby screen. By way of example, with respect to the traffic widget <b>132</b> described above, the user <b>180</b> may input into the control application <b>124</b> the locations of places that the user <b>180</b> frequently travels to such as, for example, the locations of his or her home and office and/or routes that the user <b>180</b> frequently travels. To the extent that detailed traffic information is available from, for example, a relevant department of transportation or other source, the traffic widget <b>132</b> may provide a traffic summary that is customized based on a particular route that the user <b>180</b> is most likely to travel. For example, on weekday mornings, the control application <b>124</b> could instruct the traffic widget <b>132</b> to obtain traffic information for a pre-defined route from the user's home to office. In this manner, the traffic summary <b>210</b> provided by the traffic widget <b>132</b> would not simply display generalized information that summarized the average traffic intensity over some region, but instead could provide a summary that is based on known accidents and/or traffic flow parameters on the actual route that the user <b>180</b> takes each morning to work. On weekday evenings, the control application <b>124</b> could similarly instruct the traffic widget <b>132</b> to obtain traffic information for a pre-defined route from the user's office back to the user's home. In alternative embodiments, the control application <b>124</b> could make the home and office locations directly available to the traffic widget <b>132</b> so that the traffic widget <b>132</b> could automatically obtain the most relevant traffic information without input and/or instructions from the control application <b>124.</b>

0038The control application <b>124</b> may consider a number of different parameters in determining what information to include on the standby screen at any given time. One category of parameters that will often be considered is temporal parameters such as the time of day, the day of the week and/or the day of the year. Many individuals generally follow fixed schedules throughout much of their day, waking at the same time, traveling to and from work or school at approximately the same time, eating meals at approximately the same time, etc. However, these patterns may change on particular weekdays, on weekends, etc. Pursuant to embodiments of the present invention, information regarding these patterns may be programmed into or otherwise made available to the control application <b>124.</b> The control application <b>124</b> may then use this information to select the information that is displayed on the standby screen at any given time that is likely to be the most relevant information to the user <b>180.</b>

0039Another parameter that may be considered by the control application <b>124</b> in determining what information to include on the standby screen at any given time is the current location of the cellular telephone <b>100.</b> This location information may be obtained in a variety of ways known to those of skill in the art including, for example, by obtaining the location information directly from a Global Positioning Satellite receiver that is collocated and/or part of the cellular telephone <b>100</b> or by determining an approximate location of the cellular telephone <b>100</b> based on the respective strengths of signals received from multiple cellular base stations and the known locations of those base stations. This location information may be combined, for example, with other stored location information in determining what information to display on the standby screen. For example, when the location of the cellular telephone <b>100</b> matches a pre-stored location of the user's office, the control application <b>124</b> may display information provided by work-related widgets on the standby screen such as a calendar widget <b>134,</b> a task widget <b>136,</b> a message widget <b>138</b>, etc.

0040Yet another parameter that may be considered by the control application <b>124</b> in determining what information to include on the standby screen at any given time is the location of other selected individuals ("presence information") as determined, for example, by a measured or calculated location of each individual's cellular telephone <b>100</b>. For example, upon receiving notification (or detecting) that a pre-selected friend or family member of user 180 is nearby, the control application <b>124</b> may display information provided by a presence widget <b>137</b> such as the name and current location of the nearby pre-selected friend or family member.

0041It will also be appreciated that numerous other parameters may be considered by the control application <b>124</b> in determining what information to include on the standby screen at any given time. Such parameters may include, for example, a certain condition being met. By way of example, the user <b>180</b> may want to be notified when the outside temperature reaches or exceeds a certain level (e.g., 90 °F). The current weather widget <b>130</b> or some other application may monitor a third party server or other information source for temperature data, and upon detecting that the temperature has exceeded 90 °F, the pre-defined rules may be set up so that a message or icon is displayed on the standby screen that notifies the user that the outside temperature has reached 90 °F. In addition, input from the user may also comprise one or more of the parameters that are considered. By way of example, the user <b>180</b> could input into the control application <b>124</b> (by a voice command, selecting a menu option or other conventional techniques for making a selection or entering information) an indication that the user <b>180</b> is currently involved in work activities. This input information could then be considered in determining the information that is displayed on the standby screen. A wide variety of information may be input by a user <b>180</b> according to certain embodiments of the invention including, for example, mood data (happy, sad, etc.) or current activity data (work, social, home, etc.).

0042The control application <b>124</b> applies one or more criteria to the selected parameters to determine the information that is displayed on the standby screen at any given time. As noted above, these criteria may comprise a set of pre-defined rules that select the information that is displayed. It will also be understood that this set of pre-defined rules may consider a combination of different parameters to determine the information that is displayed at any given time on the standby screen. By way of example, the set of pre-defined rules may consider the time of day, the day of the week and the location of the user <b>180</b> to determine whether or not to display information provided by the calendar widget <b>134</b> on the standby screen. As a specific example, in one relatively simple embodiment, if the day of the week is a weekday, the time of day is between 7:00 a.m. and 6:30 p.m. and the location of the user <b>180</b> is within 1 mile of the user's office, then information provided by the calendar widget <b>134</b> is displayed on the standby screen. The totality of rules that are used to determine the information that is displayed on the standby screen may also be quite complex. For example, the sensing of the near-by presence of one or more selected individuals could override the rule specifying that the information from the calendar widget <b>134</b> is displayed. The importance of the information content provided by the standby screen applications <b>122</b> could also be considered by the rules that are used to determine the information that is displayed on the standby screen. By way of example, identification by the traffic widget <b>132</b> that traffic conditions are very congested or that an accident has occurred on a route that is often taken by the user <b>180</b> could increase the probability (or mandate) that such information from the traffic widget <b>132</b> is selected for display on the standby screen.

0043As shown in <figref idref="f0004"><b>Figures 3A-3C</b></figref><b>,</b> the standby screen applications <b>122</b> provide information that may be displayed to the user <b>180</b> on a display of the cellular telephone <b>100.</b> It will be appreciated that each individual standby screen application <b>122</b> may format the information as it appears on the display or that instead the control application <b>124</b> or some other application may perform this formatting function.

0044While the standby screen applications <b>122</b> provided in embodiments of the present invention may be designed to provide relevant information to a user <b>180</b> while the cellular telephone <b>100</b> is in standby mode, it will be appreciated that one or more of the standby screen applications <b>122</b> may also provide information to the user <b>180</b> when the cellular telephone <b>100</b> is in a mode other than standby mode (e.g., while the user is engaged in a voice communication and/or when the user is actively using one of the applications <b>126</b>).

0045<figref idref="f0005"><b>Figures 4A-4C</b></figref> are illustrations showing how the standby screen that is displayed on a cellular telephone <b>100</b> according to embodiments of the present invention may change over time as information from different of the standby screen applications <b>122</b> replaces information provided by other of the standby screen applications <b>122.</b> In particular, <figref idref="f0005"><b>Figure 4A</b></figref> shows the contents of the standby screen <b>300</b> of the cellular telephone <b>100</b> at 7:15 a.m. on a particular workday. As shown in <figref idref="f0005"><b>Figure 4A</b></figref><b>,</b> the standby screen <b>300</b> includes an upper display bar <b>310</b> that includes a number of items that are often provided on the standby screen of conventional cellular telephones, including a signal strength icon <b>312,</b> a network or protocol icon <b>314,</b> a message indicator <b>316</b> (indicating that the user <b>180</b> currently has one or more unopened messages), an instant message status icon <b>318,</b> a Bluetooth enabled icon <b>320</b> and a remaining battery power icon <b>322.</b> The standby screen <b>300</b> also includes a lower display bar <b>330</b> that includes several labels <b>332, 334, 336.</b> Each label comprises a label for a "soft key" on the keypad located under each of the respective labels <b>332, 334, 336.</b> Pressing the soft key associated with label <b>332</b> opens up a call list that displays recent outgoing and/or incoming calls. Pressing the soft key associated with <b>334</b> opens up a main menu of the cellular telephone <b>100</b> from which the user <b>180</b> may access, for example, various of the applications <b>126.</b> Pressing the soft key associated with the label <b>336</b> provides the user <b>180</b> access to a widget menu that allows the user <b>180</b> to select and open any of the standby screen applications <b>122.</b>

0046As is also shown in <figref idref="f0005"><b>Figure 4A</b></figref><b>,</b> the standby screen <b>300</b> also includes a main window <b>340.</b> A display <b>342</b> of the current time, day of the week and day of the month is provided at the upper-right side of the main window <b>340.</b> The name of the cellular service provider is displayed in a display box <b>344</b> at an upper-left side of the main window <b>340.</b> The main window <b>340</b> also may include one or more background pictures or patterns <b>346.</b> Finally, the main window <b>340</b> includes one or more displays <b>350</b> of information provided by one or more of the standby screen applications <b>122.</b>

0047In the example of <figref idref="f0005"><b>Figure 4A</b></figref><b>,</b> a single display <b>350</b> is provided that includes an upper part <b>352</b> and a lower part <b>354.</b> The upper part <b>352</b> of the display <b>350</b> includes current traffic information provided by a traffic widget <b>132.</b> As the traffic summary included in upper part <b>352</b> of display <b>350</b> has already been described above with respect to <figref idref="f0004"><b>Figure 3B</b></figref><b>,</b> no further description will be provided here. The lower part <b>354</b> of the display <b>350</b> includes current weather information provided by the current weather widget <b>130.</b> As the current weather summary included in the lower part <b>354</b> of display <b>350</b> has likewise already been described above with respect to <figref idref="f0004"><b>Figure 3A</b></figref><b>,</b> no further description will be provided here.

0048Note that the standby screen <b>300</b> of <figref idref="f0005"><b>Figure 4A</b></figref> provides information that may be particularly relevant to the user <b>180</b> at 7:15 a.m. on a weekday morning. As the user <b>180</b> gets ready for work he or she can, at a glance, obtain weather information that may help him or her decide what to wear, whether to take an umbrella, etc. The user <b>180</b> is also provided with traffic information that may allow the user <b>180</b> to better assess the time at which they will need to leave for the office. All of this information is provided in an easy-to-read format. In this particular example, the control application <b>124</b> displays the information from the weather widget <b>130</b> and the traffic widget <b>132</b> based on pre-defined rules that select weather and traffic information for display at certain times of day on selected days of the week. However, it will be appreciated that, in other embodiments, other and/or additional parameters such as, for example, the location of the user <b>180</b> may instead cause the control application <b>124</b> to display information provided by the current weather and/or traffic standby screen applications <b>130, 132.</b>

0049<figref idref="f0005"><b>Figure 4B</b></figref> depicts the exemplary contents of a standby screen <b>300'</b> at 8:55 a.m. on the same day. As can be seen from <figref idref="f0005"><b>Figure 4B</b></figref><b>,</b> the contents of the standby screen <b>300'</b> are generally the same as the contents of the standby screen <b>300</b> depicted in <figref idref="f0005"><b>Figure 4A</b></figref> except that the display <b>350</b> from <figref idref="f0005"><b>Figure 4A</b></figref> has been replaced with a display <b>360</b> that displays information provided by the calendar widget <b>134.</b> Here, the pre-defined rules applied by the control application <b>124</b> may, for example, have replaced the information provided by the weather and traffic widgets <b>1.30, 132</b> with the information provided by the calendar widget <b>134</b> based on, for example, sensing that the user <b>180</b> has arrived at their office, on a weekday. At this time, on a weekday, the appointment information provided on the display <b>360</b> may be highly relevant and/or useful to the user <b>180.</b>

0050<figref idref="f0005"><b>Figure 4C</b></figref> depicts the exemplary contents of a standby screen <b>300"</b> at 12:23 p.m. on the same day. As can be seen from <figref idref="f0005"><b>Figure 4C</b></figref><b>,</b> the contents of the standby screen are generally the same as the contents of the standby screen <b>300</b> depicted in <figref idref="f0005"><b>Figure 4B</b></figref> except that the display <b>360</b> from <figref idref="f0005"><b>Figure 4B</b></figref> has been replaced with a display <b>370</b> that displays information regarding the location of selected, pre-defined individuals. The information provided in the display <b>370</b> includes a listing of the names of the individuals <b>372,</b> information regarding the location of each individual <b>374</b> and an icon <b>376</b> that is associated with each listed individual. The location information <b>374</b> may be provided by the cellular service provider based on, for example, location information generated by a GPS receiver associated with a cellular telephone of each of the selected individuals. The location information <b>374</b> may be expressed as a distance from the location of the cellular telephone <b>100</b> and/or as the name of a place associated with the location of the selected individual's cellular telephone. Thus, for example, "Mike's" location is expressed in the display <b>370</b> both in terms of a physical location ("Georgie's) and as a distance (0.3 miles) from the cellular telephone <b>100.</b> In embodiments of the present invention, the location information <b>374</b> would only be provided in instances where each of the listed individuals had given consent to the cellular service provider to provide such information to the user <b>180</b>.

0051The icons <b>376 in</b><figref idref="f0005"><b>Figure 4C</b></figref> may have a variety of meanings depending upon the particular embodiment of the present invention. In the depicted embodiment, the color of the icon depicts a category that the individual falls into. In this particular example, the color green designates friends and the color red designates co-workers. In other embodiments, the color or shape of the icon may serve as an indicator as to the distance of each individual from the user <b>180.</b> It will also be appreciated that the icons <b>376</b> may serve other purposes as well.

0052In the example of <figref idref="f0005"><b>Figure 4C</b></figref><b>,</b> the user <b>180</b> is at lunch when the display <b>370</b> is included on the main display <b>350</b> of the standby screen <b>300".</b> The user <b>180</b> is conveniently notified by the display <b>370</b> that his friend Mike is at a nearby restaurant. Thus, the example of <figref idref="f0005"><b>Figure 4C</b></figref> further demonstrates how, according to embodiments of the present invention, the right information may be provided to the user <b>180</b> at the right time and in right context.

0053In embodiments of the present invention, the standby screen applications <b>122</b> may have additional functionality other than just displaying information. For example, in the situation of <figref idref="f0005"><b>Figure 4C</b></figref><b>,</b> the user <b>180</b> may click or tap on the name Mike in portion <b>372</b> of display <b>370</b> in order to open up an instant message input screen that is pre-addressed to Mike's instant messaging address. The user <b>180</b> may then send Mike an instant message suggesting, for example, that they meet for a quick cup of coffee before returning from lunch back to work. As another example, the user <b>180</b> may tap on the display window <b>200</b> of <figref idref="f0004"><b>Figure 3A</b></figref> in order to obtain additional weather information such as, for example, the weather forecast for some number of upcoming days. Thus, the standby screen applications <b>122</b> according to embodiments of the present invention may provide both at-a-glance information as well as additional functionality such as, for example, the display of more detailed information.

0054As is clear from the above discussion, according to certain embodiments of the present invention, a user <b>180</b> may conveniently be provided with relevant information via the standby screen of the cellular telephone <b>100</b> during the time when the relevance of the information may be high. In some embodiments, the user <b>180</b> may access this information without having to navigate any menus and/or otherwise interact with the cellular telephone <b>100.</b> As shown by the above examples, over the course of the day the information provided by the widgets or other standby screen applications <b>122</b> changes in order to provide the user <b>180</b> with the information that is likely to be the most relevant at any given time, location and/or other context. This is achieved by dynamically updating and replacing the displayed information based on a variety of different parameters according to pre-defined criteria/rules.

0055It will be appreciated that in some embodiments of the present invention the widgets and other standby screen applications <b>122</b> may all be executing on the controller <b>110</b> at any given time, while in other embodiments only a subset of the standby screen applications <b>122</b> are concurrently executed. The latter approach may be used to reduce the processing requirements of the cellular telephone <b>100.</b> In such embodiments, the only standby screen applications <b>122</b> executing on the controller <b>110</b> at a given time may, for example, be the standby screen applications <b>122</b> that are currently providing information that is included on the standby screen <b>300</b> along with any standby screen applications <b>122</b> that monitor for information that might result in a change in the information provided to the user (such as, for example, a presence widget <b>137</b> and/or a message widget <b>138</b>).

0056As discussed above, the information provided by the standby screen applications may be displayed at least while the cellular telephone <b>100</b> is in the standby mode. As known to those of skill in the art, the standby mode may include both an "awake" mode in which at least one of the displays on the cellular telephone <b>100</b> is backlit or otherwise activated to provide a full color display and a "sleep" mode in which the screen is black or is black with text or graphics displayed in light gray. It will be appreciated that the information that is included on the standby screen while the cellular telephone <b>100</b> is in standby mode may be displayed in either or both the awake and sleep modes of the standby modes.

0057The control application <b>124</b> may come pre-programmed with a default set of rules that may be used to determine what information is displayed when on the standby screen. This default set of rules might, for example, specify that information from the current weather and/or traffic widgets <b>130,132</b> is displayed from 5:00 a.m. until 8:00 a.m. and from 5:30 p.m. through 7:00 p.m. on weekdays, that information provided by the calendar <b>134</b> and/or task list widgets <b>136</b> are displayed from 8:00 a.m. through 5:30 p.m. on weekdays, that information from a To-Do List widget <b>139</b> and the weather widget <b>130</b> be displayed on weekends, and that information from the presence widget <b>137</b> and/or message widget <b>138</b> may act to override other information under certain, pre-defined circumstances. By providing this default set of rules, the enhanced standby screen functionality may be up and running for the user <b>180</b> as soon as he or she activates the cellular telephone <b>100.</b>

0058As noted above, the user <b>180</b> may also be provided the capability to customize various of the features of the improved standby screen functionality provided by embodiments of the present invention. For example, the user <b>180</b> may input the location of his or her home, office and or other locations into, for example, the control application <b>124</b> and/or one or more of the standby screen applications <b>122.</b> This information may then be used by the control application <b>124</b> to execute more sophisticated rules for determining when to switch between different of the standby screen applications <b>122.</b> The user <b>180</b> can also input commonly used driving routes and the times and days of the week when those routes are typically driven in order to further customize, for example, when information from the traffic widget <b>132</b> is displayed and/or the traffic information that is provided by the traffic widget <b>132</b> (i.e., information that is customized for a specific route). An interface may be provided to allow the user <b>180</b> to conveniently input such customization information into control application <b>124.</b> The user may similarly input information regarding individuals that are to be tracked by the presence widget <b>137.</b>

0059In some embodiments of the present invention, the user <b>180</b> may also be provided capabilities to select one of the standby screen applications <b>122</b> so that information provided by the selected one of the standby screen applications <b>122</b> is displayed on the standby screen either temporarily and/or until closed by the user. By way of example, in the embodiment depicted in <figref idref="f0005"><b>Figures 4A-4C</b></figref><b>,</b> the user <b>180</b> can display a list of the available standby screen applications <b>122</b> by pressing the soft key on the keypad associated with label <b>136.</b> Once this menu is displayed, the user <b>180</b> may select one of the standby screen applications <b>122</b> using, for example, conventional techniques. This selection may act to cause the information provided by the selected standby screen application <b>122</b> to be displayed within the main display <b>350</b> (either replacing the currently displayed information or added to it) of the standby screen <b>300.</b>

0060Pursuant to further embodiments of the present invention, the user <b>180</b> may also be provided a capability to close the information displayed by a standby screen application <b>122</b> after having viewed that information. By way of example, the presence widget <b>137</b> may detect the presence of a relevant individual, and this may trigger the control application <b>124</b> to replace currently displayed information with information regarding the location of the identified individual. After the user <b>180</b> has viewed this information, the information may, in some circumstances, be considered outdated and no longer relevant. Accordingly, the user <b>180</b> may be provided a convenient mechanism for commanding the control application <b>124</b> to replace the information provided by the presence widget <b>137</b> with other information. This mechanism might, for example, involve pressing a soft key or touching a "close window" icon displayed on the standby screen <b>300.</b> The user <b>180</b> may similarly replace information provided by the weather, traffic, message and/or other widgets or applications <b>122</b> after the user <b>180</b> has viewed the displayed information. When this occurs, the control application <b>124</b> may be programmed to identify a secondary standby screen application <b>122</b> that will provide information to the standby screen in the event that the primary widget or standby screen application (i.e., the widget or application <b>122</b> specified by the set of rules/parameters) is closed by the user <b>180</b>.

0061<figref idref="f0006"><b>Figure 5</b></figref> is a flowchart illustrating methods of displaying information on a standby screen of a cellular telephone <b>100</b> according to certain embodiments of the present invention. As shown in <figref idref="f0006"><b>Figure 5</b></figref><b>,</b> operations may begin with information provided by a first of the plurality of standby screen applications <b>122</b> being displayed on a display of the cellular telephone <b>100</b> while the cellular telephone is in standby mode (block <b>400</b>). One or more pre-selected parameters are then monitored such as, for example, the time of day, the day of the week, the month, the day of the year, the location of the cellular telephone <b>100,</b> the location of other cellular telephones or individuals, etc. (block <b>410</b>). The monitored parameter information is input and/or compared to one or more pre-defined rules to determine if the rule(s) are satisfied such that information from another of the plurality of standby screen applications <b>122</b> should be displayed on the display of the cellular telephone (block <b>420</b>). If so, a second of the plurality of standby screen applications <b>122</b> is selected (block 430), and information from the selected second of the plurality of standby screen applications <b>122</b> is displayed on the display of the cellular telephone (block <b>440</b>), either by replacing the information from the first of the plurality of standby screen applications <b>122</b> or by being posted alongside or over the information from the first of the plurality of standby screen applications <b>122.</b>

0062Typically, the information provided by the standby screen applications <b>122</b> is displayed on the display screen(s) of the cellular telephone <b>100.</b> However, in some embodiments of the present invention, this information may additionally (or alternatively) be displayed on a display device of a cellular telephone accessory. By way of example, a watch that includes a liquid crystal display screen may communicate with the cellular telephone <b>100</b> via, for example, a Bluetooth or other wireless connection. In some embodiments, of the present invention, the information provided by the standby screen applications <b>122</b> may additionally or alternatively be displayed on the liquid crystal display screen of the watch in order to conveniently make the information available to the user <b>180.</b> Thus, the information may be displayed on a display of the cellular telephone <b>100</b> and/or on one or more displays that are otherwise associated with the cellular telephone <b>100</b> via, for example, a wireless link.

0063The standby screen applications <b>122</b> may come preloaded on the cellular telephone <b>100,</b> may be downloaded from various websites or servers and/or may be purchased from third party vendors either as a software package purchased in a store or as a downloadable application.

0064Herein, references are made to one or more of the standby screen applications <b>122</b> displaying "information" on the display of a cellular telephone. It will be appreciated in light of the present disclosure that, as used herein, the "information" that is displayed need not be data or text, but can be anything that is displayed on the display including, for example, text, data, icons, pictures, video clips, graphs, tables and/or the like.

0065In the drawings and specification, there have been disclosed typical embodiments of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims.
