0003Particularly, articulated robots that have a joint system similar to human joints and can operate similar to human limbs, and automatic guided vehicles that conveniently transport various materials used in the production process are representative industrial robots.

0004The penetration rate and utilization rate of industrial robots have been increasing, whereas, research and development of safety facilities for protecting users from industrial robots is somewhat inadequate. Thus, there are problems of accidents due to the use of industrial robots without proper safety facilities. In addition, disposing a physical fence in a dangerous area around the industrial robot may cause a restriction on the control of the industrial robot, requiring a lot of time and cost.

0005Accordingly, there is a need to develop a method in which a dangerous area and a safe area around the industrial robot can be easily and conveniently recognized by a worker.

0033<figref idref="f0001">FIG. 1</figref> is a block diagram illustrating an example configuration of an electronic device according to an example embodiment.

0034Referring to <figref idref="f0001">FIG. 1</figref>, an electronic device 100 includes a display 110, a camera 120, a sensor 130, a storage 140, and a processor (e.g., including processing circuitry) 150.

However, this is merely an example, and the electronic device 100 may be implemented as various types of electronic devise such as, for example, and without limitation, a wearable device that is in at least one type of an accessory type (for example: watch, ring, bracelet, ankle bracelet, necklace, glasses, contact lens, or a head-mounted-device (HMD)), an integrated type with fabric and/or clothes (for example: an electronic cloth), a robot including a driving unit, a projector, a server, or the like.

0036The display 110 may display various screens. The display 110 may be implemented as various types of displays such as, for example, and without limitation, a liquid crystal display (LCD), organic light emitting display (OLED), liquid crystal on silicon (LCoS), digital light processing (DLP), or the like.

0037The display 110 may also be coupled to at least one of a front region, a side region, and a back region of the electronic device 100 in the form of a flexible display.

0038The camera 120 may include various circuitry including a configuration for capturing a still image or a moving image under the control of the user. The camera 120 can capture a still image at a specific point of time, but may also continuously photograph a still image. The camera 120 may provide the acquired image to the processor 150 and the image may be provided to the user via the display 110. The camera 120 may be implemented as a plurality of cameras such as a front camera and a back camera.

0039The sensor 130 may be implemented as any of various sensors, such as, for example, and without limitation, a position sensor, a touch sensor, a geomagnetic sensor, a gyro sensor, an acceleration sensor, a proximity sensor, a grip sensor, or the like. However, the present disclosure is not limited thereto, and the sensor 130 may be implemented by various types of sensors 130 that can sense the state of the electronic device 100, the surrounding environment of the electronic device 100, and so on.

0040For example, the sensor 130 may sense position information of the electronic device 100. As an example, the electronic device 100 may sense position information of the electronic device using a GPS sensor. In addition, the sensor 130 may sense the photographing direction of the electronic device 100. In an example, the sensor 130 may sense the direction pointed by the back surface of the electronic device 100. The direction pointed by the rear surface of the electronic device 100 sensed by the sensor and the photographing direction of the rear surface camera provided in the electronic device 100 may be the same.

0041The storage 140 may store various data such as operating system (O/S) software module to drive the electronic device 100, various applications, contents, position information of a smart machine and work information of the smart machine, and so on.

0042The smart machine may refer, for example, and without limitation, to an industrial robot used in the manufacturing process of a product such as a factory line. For example, industrial robots can be implemented as articulated robots to replace the functions of the human arms or hands. Industrial robots may refer, for example, to all types of robots used for various purposes in the industrial field such as, for example, and without limitation, assembly, machining, warehousing/ shipment of articles, inspection &amp; measurement, press, resin processing, welding, and the like. For example, an industrial robot may be implemented as a rectangular coordinate robot, a cylindrical work robot, or a polar robot. Hereinafter, for convenience of description, a smart machine is assumed to be an industrial robot. However, this is merely an example, and the smart machine may be realized as a robot that operates in an autonomous manner by sensing ambient environment in real time based on the sensor 130 and collecting information.

0043The storage 140 may store location information and work information of the smart machine. For example, the storage 140 may include coordinate information indicating coordinates of each position of a specific space such as, for example, and without limitation, a factory, a warehouse, a building, or the like. The location information of the smart machine may be information indicating the location of the smart machine disposed in the specific space based on the coordinate information. For example, the location of the smart machine may include information represented by (x, y, z) coordinates, and the electronic device 100 can identify the location where the smart machine is located in a specific space according to the information.

0044In addition, the storage 140 may store work information of the smart machine. The work information may include information on a work schedule required for performing operations included in the work schedule of the smart machine and a work schedule. The work area may refer, for example, to the size of the space. In an example, the smart machine may perform a first operation, and the storage 140 may store information about the size of the space required to perform the first operation in the form of (w, h). Here, w may be the width of the space required to perform the first operation and h may be the height of the space required to perform the first operation. However, various types of information capable of identifying the size of the space required for the operation of the smart machine can be stored.

0045The operations performed by the smart machine can be variously set according to the purpose of the smart machine. As a non-limiting example, a smart machine may perform operations such as grab, pierce die, stock &amp; release, move, and the like. One smart machine may perform different operations sequentially according to a schedule, or one smart machine may perform only one operation repeatedly according to a schedule.

0046The work schedule according to an example embodiment may refer, for example, and without limitation, to a list of operations performed by the smart machine according to time order. The smart machine can perform an operation based on the job schedule. This will be described in greater detail below with reference to <figref idref="f0002">FIG. 4</figref>.

0047The processor 150 may include various processing circuitry and may control overall operations of the electronic device 100.

0048According to an example embodiment, the processor 150 may include various processing circuitry, such as, for example, and without limitation, one or more of a central processor (CPU), a dedicated processor, a microcontroller unit (MCU), a micro processor (MPU), a controller, an application processor (AP) , a communication processor (CP), an ARM processor, or the like. The processor 150 may be implemented as a system on chip (SoC) with a built-in processing algorithm, a large scale integration (LSI), or a field programmable gate array (FPGA).

0049The processor 150 according to an embodiment of the present disclosure may identify a smart machine located in a peripheral area of the electronic device based on the position information of the electronic device 100 sensed through the sensor 130 and the position information of the smart machine. Here, the ambient area may refer, for example, to an area within a predetermined distance from the electronic device 100.

0050According to an example embodiment, the processor 150 may identify the location of the electronic device 100 in accordance with the location information of the electronic device 100 sensed by the sensor 130, and identify a smart machine located within a predetermined distance from the location of the electronic device 100. The processor 150 may obtain the work information of the smart machine identified from the storage 140. For example, the processor 150 may identify first and second smart machines located in a peripheral region (e.g., a region within a given distance of the electronic device) of the electronic device 100 among a plurality of smart machines. The processor 150 may obtain the first work information corresponding to the first smart machine and the second work information corresponding to the second smart machine.

0051As another example, a mark may be placed in the specific space where the electronic device 100 and the smart machine are located to identify each location in, for example, the lower or upper portion of the space. For example, in the floor of the factory, a mark, an identification mark, etc. for each predetermined distance, area, and compartment can be disposed. The electronic device 100 may acquire the location information of the electronic device 100 and the location information of the smart machine based on the mark.

0052The processor 150 according to an embodiment of the present disclosure may indicate the work area of the smart machine on the image photographed through the camera 120 based on the obtained smart machine operation information and provide it on the display. For example, the processor 150 may identify an area corresponding to the position of the first smart machine based on coordinate information (x1, y1, z1) according to the position of the first smart machine in the photographed image, and shade the region corresponding to the (w1, h1) in a specific color and provide the image including the shaded region through the display 110.

0053Accordingly, the user can receive the work area of the first smart machine through the electronic device 100 as augmented reality (AR). An area shaded with a specific color on the display 110 may indicate an area where the user's access is dangerous due to the operation of the first smart machine. Without installation of a physical fence, a virtual safety fence can be provided to a user to prevent and/or reduce the possibility of an accident.

0054The processor 150 according to an embodiment of the present disclosure may identify the smart machine based on the location information of the electronic device 100 and the photographing direction of the electronic device 100. In an example, the sensor 130 may sense the direction of movement of the electronic device 100, the direction of photographing of the camera 120 (e.g., a back camera), and the processor 150 may identify smart machines based on the sensed direction.

0055The processor 150 may identify a plurality of smart machines located in a peripheral region of the electronic device 100 based on the location information of the electronic device 100 and identify a smart machine corresponding to the photographing direction among the plurality of smart machines. For example, if the smart machine corresponding to the photographing direction of the electronic device 100 among the identified first and second smart machines is the first smart machine, the processor 140 may indicate the work area based on the work information of the first smart machine. Here, the work area may refer, for example, to a width and a height (w1, h1) indicating a required area as the first smart machine operates.

0056The processor 150 in accordance with an example embodiment of the present disclosure may identify whether a smart machine is operating based on a work schedule of the smart machine. However, in an example embodiment, the processor 150 may identify whether the smart machine is performing an operation based on the image photographed through the camera 120, in addition to the work schedule. The processor 150 may indicate and provide a work area if the smart machine is identified as being operational. The work schedule may include at least one of an operation of the smart machine, a time required for the operation, and a stand-by time between operations.

0057The processor 150 according to an example embodiment, if it is identified that the smart machine is operating, may provide information on a remaining time until an operation of the smart machine is ended.

0058According to another example embodiment, if it is identified that the smart machine is not operating, information on a remaining time until the operation of the smart machine starts can be provided.

0059As a non-limiting example, it can be assumed that the smart machine operates between time t1 and time t2. The processor 150 may, based on the work schedule, provide information about the time remaining until time t2 if the smart machine is identified as being operational. As another example, if the smart machine is identified as not operating, it may provide information about the time remaining until time t1.

0060The processor 150 according to an example embodiment of the present disclosure can acquire work information by analyzing an image of the smart machine taken through the camera 120 for a preset time. For example, the processor 150 may analyze an image captured by the smart machine for a predetermined time to acquire at least one of the operation time of the smart machine, the required time for the operation and the waiting time between operations, thereby obtaining work information. However, in an example embodiment, the processor 150 may acquire work information of the smart machine according to various methods, and store the acquired work information in the storage 140. A description thereof will be described in greater detail below with reference to <figref idref="f0002">FIG. 4</figref>.

0061The processor 150 may update the smart machine's work information by analyzing the image of the smart machine photographed for a preset time. As a non-limiting example, according to the work schedule stored in the storage 140, the smart machine may operate between times t1 and t2, and may operate between times t3 and t4. On the other hand, according to the image photographed for a predetermined time, the smart machine operates between time t2 and t3, and can operate between times t4 and t5. Accordingly, the processor 150 may update the task information for the smart machine stored in the storage 140, replace it with the updated work information, and store the updated work information.

0064The camera 120 may include, for example, a lens, a shutter, a diaphragm, a solid-state image photographing device, an analog front end (AFE), a timing generator (TG), and the like. The shutter adjusts the time the light reflected from the subject enters the user terminal device 100, and adjusts the amount of light incident on the lens by mechanically increasing or decreasing the size of the aperture through which the light enters. The solid-state image photographing device outputs an electric signal as an image due to the photoelectric charge when light reflected on the object is accumulated in the photo-electric charge. The TG outputs a timing signal for reading out the pixel data of the solid-state image pickup device, and the AFE samples the electric signal output from the solid-state image pickup device and digitizes the electrical signal.

The pressure sensitive type touch sensor may include, for example, and without limitation, two electrode plates built in the electronic device 100. When the user touches the upper and lower plates of the touched point, the pressure sensitive type touch sensor senses that the current flows. In addition, various other touch sensing circuitry, such as, for example, and without limitation, infrared sensing, surface ultrasonic conduction, integral tension measurement, piezo effects, or the like, may be used to detect touch interactions.

0067In addition, the electronic device 100 may use various other touch sensing circuitry, such as, for example, and without limitation, a magnetic and magnetic field sensor, a light sensor, a proximity sensor, or the like, instead of the touch sensor to determine whether or not the touch object such as, for example, a finger or a stylus pen has come into contact with or in proximity to the touch object.

0068The geomagnetic sensor may refer, for example, to a sensor for sensing the rotating state and the moving direction of the electronic device 100, and the like. The gyro sensor may refer, for example, to a sensor for sensing the rotation angle of the electronic device 100. Both the geomagnetic sensor and the gyro sensor may be provided, but even if only one of them is provided, the user terminal device 100 can detect the rotation state.

0069The acceleration sensor may, for example, refer to a sensor for sensing the degree of tilting of the electronic device 100.

0070The proximity sensor may refer, for example, to a sensor for sensing the approaching motion without touching the display surface directly. The proximity sensor may be implemented as various types of sensors such as, for example, and without limitation, a high-frequency oscillation type that forms a high-frequency magnetic field and senses a current induced by a magnetic field characteristic that changes when approaching an object, a magnetic type using a magnet, a capacitive type which senses capacity which changes due to approach of the object, and the like.

0071The grip sensor may refer, for example, to a sensor that detects the grip of a user by being disposed on the rear surface, the rim, and the handle, separately from the touch sensor provided on the touch screen. The grip sensor may be implemented as a pressure sensor in addition to the touch sensor.

0072The storage 140 may be implemented as an internal memory such as a ROM or a RAM included in the processor 150 or may be implemented as a separate memory from the processor 150. In this case, the storage 140 may be implemented in the form of a memory embedded in the electronic device 100, or a removable memory in the electronic device 100, depending on the purpose of data storage. For example, in the case of data for driving the electronic device 100, it is stored in a memory embedded in the electronic device 100, and in the case of data for the extended function of the electronic device 100, the data can be stored in a memory which can be attached to or detached from the electronic device 100.

0073The memory embedded in the electronic device 100 may be implemented, for example, and without limitation, as a non-volatile memory, a volatile memory, a hard disk drive (HDD), or a solid state drive (SSD) A micro SD card, a USB memory, etc.), an external memory (for example, a USB memory) that can be connected to the USB port, and the like.

0074The processor 150 may include various processing circuitry and controls overall operations of the electronic device 100 using various programs stored in the storage 140.

0075For example, the processor 150 may include a RAM 151, a ROM 152, a main CPU 153, a graphic processor 154, first to nth interface 155-1 ~ 155-n, and a bus 156.

0077The first through n interfaces 155-1 to 155-n may be connected to the various components described above. One of the interfaces may be a network interface connected to an external device via a network.

0078The main CPU 153 accesses the storage 140 and performs booting using the O / S stored in the storage 140. Then, various operations are performed using various programs stored in the storage 140.

0079The ROM 152 stores a command set for booting the system and the like.

The processor 150 communicates with several external devices and smart machine using the communicator 160.

0083The Wi-Fi chip 161 and the Bluetooth chip 162 communicate with each other using WiFi or Bluetooth. When the WiFi chip 161 or the Bluetooth chip 162 is used, various connection information such as an SSID and a session key may be transmitted and received first, and communication information may be used to transmit and receive various information. The wireless communication chip 163 refers to a chip that performs communication according to various communication standards such as IEEE, Zigbee, 3rd Generation (3G), 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE). The NFC chip 164 means a chip operating in a Near Field Communication (NFC) mode using 13.56 MHz band among various RF-ID frequency bands such as 135 kHz, 13.56 MHz, 433 MHz, 860 to 960 MHz, and 2.45GHz.

0084The processor 150 according to an embodiment of the present disclosure may communicate with a server (not shown) to obtain work information of a smart machine. For example, when the product name of the smart machine is input, the processor 150 receives the work information of the smart machine corresponding to the product name from the server through the communication unit 160, and stores the received work information in the storage 140. However, the present disclosure is not limited thereto, and may acquire work information of a smart machine through any suitable means, including, for example, and without limitation, a keyword search that characterizes a smart machine. For example, it is of course possible to search Pick &amp; Place Robot, 6-axis multi-joint robot, and the like, and obtain and store work information from search results.

0085As another example, the processor 150 may communicate with a smart machine disposed nearby the electronic device 100 or within a predetermined scope through the Wi-Fi chip 161, Bluetooth chip 162, the NFC chip 164, etc. to obtain at least one of the position information and work information of the smart machine.

0086The driving unit 170 may include various driving circuitry for moving the main body of the electronic device 100. Generally, the driving unit 170 of the electronic device 100 may include left and right motors. The driving unit 170 may selectively move the left and right motors so that the main body of the electronic device 100 may be moved forward, backward, and rotated. In addition, the driving unit 170 may include a driving wheel and a castor. The driving wheels may be connected to the left and right motors so that two driving motors may be disposed symmetrically on the left and right edges of the central region of the lower portion of the main body of the electronic device 100. However, it should be understood that this may include various types of drivers that enable movement of the electronic device 100.

0087For example, the driving unit 170 may be driven such that the electronic device 100 is located within a predetermined distance from the user, under the control of the processor 150. For example, the processor 150 can detect the user and control the driving unit 170 to be positioned within a distance of 1 m from the sensed user. Even when the user moves, the electronic device 100 can detect the position of the changed user in real time and move to correspond to the position of the user.

0088According to an embodiment of the present disclosure, when the position information of the electronic device 100 is changed according to the control of the driving unit 170, the electronic device 100 may identify a smart machine located at a peripheral area of the electronic device 100 based on the changed position information. The electronic device 100 can identify, in real time, a smart machine located in the peripheral area of the user who is moving, taking into account the movement of the user, and provide an indication of the work area of the identified smart machine.

0089A projector (not shown) may, for example, irradiate a beam to the work space of the smart machine based on the work information of the identified smart machine. For example, in addition to providing an indication of a work area on a photographed image, the electronic device 100 may also irradiate the beam to the workspace of the identified smart machine and make the user to recognize the work area.

0090In an example, the projector may irradiate a first beam having a particular color in the work space of the smart machine. In order to make a user recognize the work area intuitively and prevent and/or reduce accidents, the projector can irradiate the workspace with a red beam.

0091The projector according to an example embodiment of the present disclosure may, based on distance information for recognizing at least one of a user's motion and a user's voice by the smart machine, irradiate the second beam which guides a recognizable position regarding at least one of the user's motion and voice. For example, the smart machine may recognize at least one of the user's motion and voice, and the electronic device 100 may include information about the minimum distance that the smart machine requires to recognize motion and voice without malfunction. The electronic device 100 may illuminate a second beam guiding the recognizable position to a user who wants to control the smart machine using at least one of motion and voice based on information about the minimum distance. For example, a green beam can be illuminated to distinguish it from the working area of a smart machine.

0092The projector according to an example embodiment of the present disclosure may include a display panel (not shown) which receives a signal and displays the same, a lamp (not shown) which illuminates light to a display panel, and a projection lens (not shown) which adjusts a focus of the beam which passed through the display panel.

0093The display panel may be a translucent or semi-translucent LCD panel, the lamp may be an LED, and the projection lens may include a diverse combination of lens assemblies capable of focusing adjustment. The projector according to an embodiment may receive a signal from the processor 150 and display it on the display panel. The lamp may irradiate light to the display panel, and focus the image beam passing through the display panel using the projection lens, to display the work area to the user. However, this is merely an example, and the projector can be implemented by a projector of a wide variety of types, and the beam can be irradiated to a region corresponding to a work area. As an example, the projector may be implemented as a detachable projector.

0094In addition, the projector according to an example embodiment may include a hologram device (not shown) and may provide a hologram to the workspace of the smart machine based on the signal received from the processor 150.

0095The speaker 180 may refer, for example, to a component for outputting various kinds of audio data, various kinds of notification sounds, voice messages, and the like. For example, if the electronic device 100 senses the user and the user is identified as being located in the work area of the smart machine according to the detection result, the speaker 180 may output a notification. However, this is merely an example, and if the sensed user is identified as being located within a predetermined distance in the work area, the processor 150 may control the speaker 180 to output an alarm sound.

0096The input unit (not shown) may include various input circuitry, such as, for example, and without limitation, a touch panel, a pen sensor, a key, a microphone, or the like, to receive various inputs. The touch panel may be configured by combining the display 110 and a touch sensor (not shown), and the touch sensor may use, for example, and without limitation, at least one of an electrostatic type, a pressure sensitive type, an infrared type, an ultrasonic type, or the like.

In addition, when the user inputs work information of the smart machine through the input unit, the processor 150 may store the inputted work information in the storage 140.

0098Hereinbelow, the operations of the electronic device 100 will be described in greater detail below with reference to the various drawings.

0099<figref idref="f0002">FIG. 3</figref> is a diagram illustrating an example work area according to an example embodiment.

0100As shown in <figref idref="f0002">FIG. 3</figref>, the electronic device 100 may be implemented as a user terminal device. The electronic device 100 may obtain position information of the electronic device 100 through the sensor 130.

0101The electronic device 100, based on the position information of the electronic device 100 and the smart machine, may identify a smart machine located within a peripheral area of the electronic device 100. For example, the first to third machines 200, 300, and 400 can be identified.

0102The electronic device 100 may obtain the work information of each of the identified first to third smart machines 200, 300, and 400. The electronic device 100 may identify whether each of the first to third smart machines 200, 300, and 400 is operating based on the obtained operation information. For example, if the second and third smart machines 300 and 400 are identified as being in operation, the requested work area may be obtained according to the operation of the second and third smart machines 300 and 400.

0103The electronic device 100 according to an example embodiment of the present disclosure may provide an indication of a work area of a smart machine to an image photographed through the camera 120. Here, the image photographed through the camera 120 may be a pre-stored image, or may be an image received in real time through the camera 120.

0104The electronic device 100 according to an embodiment of the present disclosure may identify the smart machine based on the position information of the electronic device 100 and the photographing direction of the electronic device 100. For example, if the first through third smart machines 200, 300, and 400 are included in the image received in real time via the camera 120 according to the photographing direction of the electronic device 100, based on the work information of the first to third smart machines 200, 300 and 400, the work areas of the first to third smart machines 200, 300 and 400 can be indicated and displayed.

0105Here, the configuration for indicating the work area may refer, for example, to shading processing and color processing so that the work area is separated from the rest area in the image. For example, the area corresponding to the work area of the second smart machine 300 can be shaded in red and displayed. The electronic device 100 may inform the user that the shaded area in red color is a dangerous area.

0106The dangerous area according to another embodiment of the present disclosure may be changed according to the setting of the user. As an example, the electronic device 100 may provide a UI for setting a safety level. If the highest level is set at the safety level divided into upper, middle, and lower levels, a 1-2 m area can be added to the work area 20 of the smart machine to indicate the dangerous area (see, e.g., <figref idref="f0005">FIG. 9</figref>). The electronic device 100 may not only consider the work area of the smart machine, but may also indicate the danger area by considering the safety level. The 1-2m is merely an example, and it is not limited thereto, and it is needless to say that various changes may be made according to the purpose.

0107The electronic device 100 may also indicate and provide information about the non-operational smart machine to the image. For example, if the first smart machine 200 is identified as not operating, the electronic device 100 may make the peripheral area of the first smart machine 200 or the area corresponding to the work area according to the operation of the first smart machine 200 in green color so that the area is divided from other areas. The electronic device 100 may make a user recognize that the area in green is a safe area.

0108<figref idref="f0002">FIG. 4</figref> is a diagram illustrating an example work schedule according to an example embodiment.

0109Referring to <figref idref="f0002">FIG. 4</figref>, the electronic device 100 may include work information of a smart machine, and the work information may include information on a work schedule of a smart machine and a job area required to perform an operation included in the work schedule.

0110Here, the work schedule may refer, for example, to a list of operations according to the time of the smart machine. As illustrated in <figref idref="f0002">FIG. 4</figref>, according to the work schedule, the first smart machine 200 performs an operation between a time t and a time t1, and the corresponding operation is performed when a region (w, h) is required at positions (x, y, z). Also, the second smart machine 300 is under stand-by without performing an operation at times t2 to t4, and may perform a required operation in which a region (w, h) is required at a position (x, y, z) from time t4 to t5.

0111The electronic device 100 may be configured to perform a plurality of operations based on a work schedule for each of a plurality of smart machines and information on a work area required to perform an operation included in the work schedule, and can identify the work area (or space) required to perform the operation.

0112For example, the first to third smart machines 200, 300, and 400 may be disposed in a factory, and the electronic device 100 may include work information for each of the first to third smart machines 200, 300, 400. The electronic device 100 may identify a required work area as each of the first to third smart machines 200, 300, and 400 operates at tx based on the work information. Here, since the work area is an area where the smart machine is operated, it may refer, for example, to a dangerous area where the user's access is restricted.

0113<figref idref="f0003">FIG. 5</figref> is a diagram illustrating an example method for providing a work area according to an example embodiment.

0114Referring to <figref idref="f0003">FIG. 5</figref>, the work information of the smart machine can be input manually or automatically. The manual input method according to the example embodiment may include, based on whether the smart machine is fixed, maximum / minimum output torque of the smart machine, maximum / minimum speed of the smart machine, types of operations (grab, pierce, release, move, tec.), and required time for each operation, generating and storing work information of the smart machine based on the input data. In the meantime, it is merely an example and it is not necessary that all the data is input, and the electronic device 100 may generate a work schedule based on input data and data received from the server.

0115The automatic input method according to another embodiment of the present disclosure may be a method of receiving and storing work information of a smart machine from a server. For example, when the product name of the smart machine is input, it is possible to receive the operation information corresponding to the product name. However, the present disclosure is not limited thereto. In another embodiment, when an image photographed by the smart machine through the camera 120 for a predetermined time or more is received, the electronic device 100 may analyze the image to generate work information. By analyzing the image, and acquiring at least one of the operation of the smart machine, the time required for the operation, and the waiting time between the operations, the work information can be generated.

0116<figref idref="f0003">FIG. 6</figref> is a diagram illustrating an example electronic device according to another example embodiment.

0117Referring to <figref idref="f0003">FIG. 6</figref>, the electronic device 100 may provide additional information in addition to indicating and providing the work area to the photographed image.

0118As a non-limiting example, if a smart machine is identified as being operational based on a work schedule, the electronic device 100 may provide information about the time remaining until the operation ends on the photographed image. For example, as illustrated in <figref idref="f0003">FIG. 6</figref>, "time to safe" indicating the remaining time until the dangerous area becomes a safe zone can be displayed as the operation is terminated.

0119Also, if the electronic device 100 is identified as not being in operation, the electronic device 100 may provide information about the time remaining until the operation of the smart machine is started. For example, as shown in <figref idref="f0003">FIG. 6</figref>, the "time to critical" indicating the remaining time until the safety area becomes a dangerous area can be displayed as the operation is started.

0120The electronic device 100 according to an embodiment of the present disclosure may display information about an operation when a user input to the displayed information is received. For example, if information about the time remaining until the smart machine starts to operate according to user input is touched, the electronic device 100 may display a description of the operation, the area (or space) required for the smart machine to perform the operation, and the like.

0121<figref idref="f0004">FIGS. 7 and 8</figref> are diagrams illustrating an example electronic device according to another example embodiment.

0122Referring to <figref idref="f0004">FIG. 7</figref>, the electronic device 100 includes a driving unit 170, and may be implemented in a form capable of moving by itself by controlling the driving unit 170. The electronic device 100 may sense the user and may control the driving unit 170 to position the electronic device 100 within a predetermined distance from the sensed user.

0123When the position of the electronic device 100 is changed as the driving unit 170 is controlled, the electronic device 100 may identify the smart machine located in the peripheral area by reflecting the changed position in real time. In an example, if the electronic device 100 is moved from the first location to the second location, and a smart machine located in the peripheral region of the electronic device 100 is changed from the first smart machine 200 to the second and third smart machines 300, 400, the electronic device 100 may acquire work information of the second and third smart machines 300, 400.

0124The electronic device 100 may display an image indicating a work area of the second and third smart machines 300, 400.

0125The electronic device 100 according to an embodiment of the present disclosure may irradiate a beam to a work space according to work information using a projector. As illustrated in <figref idref="f0004">FIG. 7</figref>, the electronic device 100 includes a beam projector function, and based on the position information and work information of the first to third smart machines 200, 300, 400 from among the peripheral area of the electronic device 100, and may indicate the work area (or dangerous area) by irradiating beam to the work space.

0126Referring to <figref idref="f0004">FIG. 8</figref>, the electronic device 100 may be include a beam projector disposed in a ceiling of a specific space. The beam projector can illuminate the beam that indicates the work space of the smart machine.

0127As illustrated in <figref idref="f0004">FIG. 8</figref>, the first to third beam projectors 100-1, 100-2 and 100-3 may be arranged to correspond to the first to third smart machines 200, 300 and 400, respectively. However, the present disclosure is not limited thereto, and one beam projector may irradiate a plurality of beams to irradiate beam to a work space of each of the plurality of smart machines. The first through third beam projectors 100-1, 100-2, 100-3 may be connected to perform communication between the first through third beam projectors 100-1, 100-2, 100-3, and may be wirelessly connected or connected by wire to the body of the electronic device 100 as a component of the electronic device 100.

0128<figref idref="f0005">FIG. 9</figref> is a diagram illustrating an example of a recognizable position according to an example embodiment.

0129The smart machine according to an example embodiment of the present disclosure can be controlled based on the user's biological information such as motion recognition, voice recognition, and the like. As an example, if a "power off voice command is received, the smart machine may be turned off.

0130The electronic device 100 according to an example embodiment may include information about the maximum distance between the smart machine and the user required for the smart machine to easily recognize the user's motion and voice. Here, the maximum separation distance may refer, for example, to a situation in which the smart machine cannot correctly recognize the motion, voice, etc. of the user who is distant from the smart machine by the maximum separation distance. For example, if the distance is more than 5 m from the smart machine, the smart machine may not easily identify the user's motion, voice, etc., and the error rate of the smart machine may increase. The electronic device 100 may indicate information about the maximum separation distance.

0131In an example, if the electronic device 100 is implemented as a user terminal device, the work area 20 of the second smart machine 300 is indicated to the image photographed through the camera, and the recognizable position 30 regarding at least one of the motion and voice can be indicated and provided.

0132As another example, when the electronic device 100 is embodied as a projector, the projector may irradiate the first beam to the work space along the work area 20 of the second smart machine 300, and irradiate the second beam with a space according to the recognizable position 30. Based on the irradiated first and second beams, the user can recognize that the area irradiated with the first beam is the dangerous area and the area irradiated with the second beam is the area where the user should be located.

0133<figref idref="f0005">FIG. 10</figref> is a flowchart illustrating an example controlling method of the electronic device according to an example embodiment.
