The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a fifth generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a fourth generation (4G) network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the millimeter wave (mmWave) band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20 gigabits per second (Gbps) or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1 ms or less) for implementing URLLC.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101.

According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102 or 104, or the server 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, requests the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

Hereinafter, a description will be given of components of an electronic device and an operation of each component according to an embodiment with reference to FIG. 2.

FIG. 2 is a block diagram of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 2, in a block diagram 200, an electronic device 201 (e.g., an electronic device 101 of FIG. 1) may include a camera 210 (e.g., a camera module 180 of FIG. 1), a touch panel 220 (e.g., a display module 160 of FIG. 1), a display 230 (e.g., the display module 160 of FIG. 1), a communication circuit 240 (e.g., a communication module 190 of FIG. 1), a processor 250 (e.g., a processor 120 of FIG. 1), and a memory 260 (e.g., a memory 130 of FIG. 1).

According to an embodiment, the camera 210 may be disposed in a housing of the electronic device 201 and may capture an external environment of the electronic device 201. According to an embodiment, the camera 210 may be disposed towards the same direction as a direction where a display area of the display 230 is exposed. For example, the camera 210 obtains an image of a user facing the camera 210 across the display 230.

According to an embodiment, the camera 210 may include a plurality of cameras. The plurality of cameras may include a first camera disposed towards the same direction as a direction the display area of the display 230 is exposed and a second camera disposed towards a direction opposite to the direction of the first camera.

According to an embodiment, the touch panel 220 may detect a touch input of the user and may identify an input location thereof. For example, the touch input of the user includes contact or pressure of the user using his or her finger or a stylus pen. According to an embodiment, the touch panel 220 may be integrally formed with the display 230 or may be separately formed to be attached to the display 230. The location of the touch input of the user, which is identified using the touch panel 220, may correspond to a location on the display 230.

According to an embodiment, the display 230 may visually provide the user with information through the display area. According to an embodiment, the display 230 may display an image obtained by the camera 210 or various graphic user interfaces (GUIs).

According to an embodiment, the communication circuit 240 may assist in establishing a communication channel (a wired communication channel or a wireless communication channel) between the electronic device 201 and an external electronic device 203 and transmitting and receiving data over the established communication channel. According to an embodiment, the communication circuit 240 may communicate with the external electronic device 203 over a network 202 (e.g., wifi, cellular network, or the Internet). According to an embodiment, the communication circuit 240 may communicate with at least one external electronic device (e.g., the external electronic device 203) over the network 202.

According to an embodiment, the processor 250 may be operatively connected with the camera 210, the touch panel 220, the display 230, and the communication circuit 240. According to an embodiment, the processor 250 may display the image obtained by the camera 210 on the display 230. According to an embodiment, the processor 250 may provide a preview image of the image obtained by the camera 210 in real time using the display 230.

According to an embodiment, the processor 250 may request a video call from the external electronic device 203 through the communication circuit 240 or may receive a video call request form the external electronic device 203. According to an embodiment, as the video call between the electronic device 201 and the external electronic device 203 is connected, the processor 250 may transmit the real-time image obtained by the camera 210 to the external electronic device 203 through the communication circuit 240 and may receive a real-time image obtained by a camera of the external electronic device 203 through the communication circuit 240.

According to an embodiment, the processor 250 may display the image received from the external electronic device 203 through the communication circuit 240 on the display 230. According to an embodiment, the processor 250 may display a first image obtained by the camera 210 and a second image received from the external electronic device 203 through the communication circuit 240 on the display 230. According to an embodiment, when the electronic device 201 is making a video call connection with the external electronic device 203, the first image and the second image may include preview images obtained by the respective cameras. The first image may include a preview image obtained by the camera 210, and the second image may include a preview image obtained by the camera of the external electronic device 203.

According to an embodiment, the processor 250 may generate augmented reality content based on a user input through the touch panel 220. The augmented reality content may include a virtual 3D object generated in a shape drawn according to the user input. According to an embodiment, the user input for generating the augmented reality content may include a touch input using a finger of the user or a stylus pen. The processor 250 may track a touch input using the touch panel 220 and may connect a trajectory thereof using points or lines to generate a virtual object.

According to an embodiment, the processor 250 may display the generated augmented reality content on at least one of the first image obtained by the camera 210 or the second image received through the communication circuit 240. The processor 250 may additionally display the virtual object on an image of a real environment (e.g., the first image or the second image), which is obtained by the camera 210 or the camera of the external electronic device 203. The processor 250 may overlap and display the augmented reality content with the first image or the second image on the display 230 in response to the location where the user input is detected using the touch panel 220.

According to an embodiment, the processor 250 may fix and display the augmented reality content with respect to a subject recognized from the image. For example, the processor 250 displays the augmented reality content to move together depending on motion of the subject.

According to another embodiment, the processor 250 may fix and display the augmented reality content on specific coordinates of a space recognized based on a three-dimensional coordinate system (e.g., a spherical coordinate system) from the image. For example, although the space captured by the camera (e.g., the camera 210) or a location of the space is changed, the processor 250 displays the augmented reality content to remain in a fixed location. In this case, the processor 250 may fail to display the augmented reality content on the image of the camera, which is displayed on the display 230, as the location where the augmented reality content is fixed deviates from a field of view of the camera, and may display the augmented reality content on the image of the camera, which is displayed on the display 230, as the location where the augmented reality content is fixed enters the field of view of the camera.

According to an embodiment, the processor 250 may transmit augmented reality content generated based on a user input, which is input from a first user who is the user of the electronic device 201, to the external electronic device 203 through the communication circuit 240. For example, as the video call between the electronic device 201 and the external electronic device 203 is connected, the processor 250 transmits the augmented reality content displayed on the image (e.g., the first image or the second image) to the external electronic device 203. According to an embodiment, the augmented reality content may include a virtual object generated based on the user input and location information where the virtual object is mapped to a specific image. The external electronic device 203 may display the augmented reality content received through the communication circuit 240 at a mapped location of a specified image (e.g., the first image or the second image).

According to an embodiment, the processor 250 may receive augmented reality content generated based on a user input, which is input from a second user who is a user of the external electronic device 203, through the communication circuit 240. For example, as the video call between the electronic device 201 and the external electronic device 203 is connected, the processor 250 receives the augmented reality content displayed on the image (e.g., the first image or the second image) from the external electronic device 203. The processor 250 may display the augmented reality content received through the communication circuit 240 at a mapped location of the specified image (e.g., the first image or the second image).

According to an embodiment, the processor 250 may display the augmented reality content generated by the electronic device 201 or the augmented reality content generated by the external electronic device 203 in different colors. In other words, a plurality of users who are making a video call with each other may identify a user who generates the augmented reality content based on the color of the augmented reality content.

According to an embodiment, the processor 250 may display an animation effect of the augmented reality content based on the user input through the touch panel 220. The animation effect of the augmented reality content may include a series of graphic effects indicating a process where a virtual object is moved or where a shape or color of the virtual object is changed.

According to an embodiment, the processor 250 may display an animation effect of first augmented reality content using second augmented reality content, in response to the user input through the touch panel 220. Hereinafter, the first augmented reality content may refer to augmented reality content displayed on the first image, and the second augmented reality content may refer to augmented reality content displayed on the second image. The user input for displaying the animation effect may include various touch inputs, for example, a tap or a double tap of the first augmented reality content or drag and drop for dragging and dropping the first augmented reality content onto a location adjacent to the second augmented reality content (e.g., into an area where the second image is displayed).

As another example, the user input for displaying the animation effect includes a touch input for moving the first augmented reality content by the first user and a touch input for moving the second augmented reality content by the second user. In this case, as it is determined that a distance between the first augmented reality content and the second augmented reality content is within a certain range, the processor 250 may display the animation effect of the first augmented reality content using the second augmented reality content.

According to an embodiment, the animation effect of the first augmented reality content using the second augmented reality content may include a graphic effect where the first augmented reality content interacts with the second augmented reality content. According to an embodiment, the animation effect may be differently specified according to an object included in the augmented reality content and may be stored in the electronic device 201, the external electronic device 203, or an external server (e.g., a server 108 of FIG. 1) connected over the network 202.

According to an embodiment, the processor 250 may identify at least one object included in the first augmented reality content and the second augmented reality content and may display an animation effect corresponding to the object identified from the first augmented reality content and the second augmented reality content among animation effects specified according to the objects on the display 230. For example, as a first object is identified from the first augmented reality content and a second object is identified from the second augmented reality content, the processor 250 displays a first animation effect corresponding to the first object and the second object on the display 230. The first object and the second object may be the same object or different objects.

According to an embodiment, the animation effect may include at least one animation effect for the same object, and the at least one animation effect may be mapped to different user inputs. The processor 250 may receive the user input through the touch panel 220, thus displaying an animation effect mapped to the received user input on the display 230. For example, the processor 250 displays the first animation effect of the first augmented reality content using the second augmented reality content by receiving a first user input (e.g., a double tap) and may display a second animation effect of the first augmented reality content using the second augmented reality content by receiving a second user input (e.g., drag and drop).

According to an embodiment, the processor 250 may transmit the animation effect to the external electronic device 203 through the communication circuit 240, and the external electronic device 203 may display the animation effect on its display.

According to an embodiment, the memory 260 may store various pieces of data used by at least one component (e.g., the processor 250 or the camera 210) of the electronic device 201. The memory 260 may be operatively connected with the processor 250 and may store one or more instructions performed by the processor 250.

According to various embodiments, the electronic device 201 may generate augmented reality content based on a user input while making a video call with at least one external electronic device (e.g., the external electronic device 203) and may transmit the generated augmented reality content to the at least one external electronic device to display the augmented reality content on the electronic device 201 and the display of the at least one external electronic device, thus sharing a visual expression between a plurality of users which are making a video call with each other. As the visual expression is shared, communication among the plurality of users may be smooth. Furthermore, the electronic device 201 may further display an animation effect indicating interaction between pieces of a plurality of augmented reality content based on the user input, thus providing the user with more various visual expressions.

Hereinafter, a description will be given of a method for providing augmented reality content in an electronic device according to an embodiment with reference to FIG. 3.

FIG. 3 is a flowchart 300 illustrating an operation of an electronic device according to an embodiment of the disclosure. Operations of the electronic device, which will be described below, may be performed by an electronic device 201 of FIG. 2 or a processor 250 of the electronic device 201.

According to an embodiment, as a video call is connected with an external electronic device, the electronic device may perform a process shown in FIG. 3.

In operation 301, the electronic device may display a first image and a second image on a display (e.g., a display 230 of FIG. 2). According to an embodiment, the first image may include an image captured by a camera (e.g., a camera 210 of FIG. 2) of the electronic device. According to an embodiment, the second image may include an image received from an external electronic device (e.g., an external electronic device 203 of FIG. 2) through a communication circuit (e.g., a communication circuit 240 of FIG. 2) of the electronic device. The second image may include an image captured by a camera of the external electronic device. According to an embodiment, the first image and the second image may be real-time image data including a preview image before the image captured by each camera of the electronic device or the external electronic device is stored.

According to an embodiment, the electronic device may receive images from a plurality of external electronic devices and may display a first image and a plurality of second images on the display.

According to an embodiment, the electronic device may transmit the first image to the external electronic device, and the external electronic device may display the first image and the second image on the display of the external electronic device.

In operation 303, the electronic device may display first augmented reality content on the first image. According to an embodiment, the first augmented reality content may be generated based on a user input detected through a touch panel (e.g., a touch panel 220 of FIG. 2) of the electronic device. The user input may include a touch input performed by a user of the electronic device using his or her finger or a stylus pen. According to an embodiment, the first augmented reality content may include a virtual object generated by the electronic device to track the touch input of the user and have a shape according to a trajectory thereof. For example, when the user of the electronic device draws on the display using the finger or the stylus pen, the electronic device imitates the shape of a picture or letter drawn by the user to generate a virtual object.

According to an embodiment, the electronic device may display augmented reality content at a location on the display where the user input for generating the augmented reality content is detected. According to an embodiment, as the user draws on an area of the display where the first image is displayed, the electronic device may generate and display first augmented reality content on the first image.

The case where the electronic device generates the virtual object having the shape according to the trajectory of the touch input is exemplified as the method for generating the augmented reality content based on the user input in the above-mentioned embodiment, but not limited thereto. The electronic device may generate a virtual object in a specified form selected based on a selective input of the user.

The case where the first augmented reality content is generated by the electronic device is exemplified in the above-mentioned embodiment, but not limited thereto. The first augmented reality content may include augmented reality content which is generated by the external electronic device and is received over the network. For example, the first augmented reality content is generated based on a touch input which is input on an area where the first image is displayed on a display of the external electronic device.

In operation 305, the electronic device may display second augmented reality content on the second image. According to an embodiment, the second augmented reality content may include augmented reality content received by the electronic device from the external electronic device. The second augmented reality content may be generated based on, for example, a user input detected through a touch panel of the external electronic device. The user input for generating the augmented reality content is described above in conjunction with the first augmented reality content, a duplicated description will be brief or omitted. For example, when the user of the external electronic device draws on the display of the external electronic device using the finger or the stylus pen, the external electronic device imitates the shape of a picture or letter drawn by the user to generate a virtual object.

According to an embodiment, the electronic device may receive and display the second augmented reality content generated by the external electronic device on the display of the electronic device. According to an embodiment, as the user of the external electronic device draws on an area of the display of the external electronic device where the second image is displayed, the electronic device may and display the second augmented reality content received from the external electronic device on the second image.

The case where the second augmented reality content is generated by the external electronic device and is received from the external electronic device is exemplified in the above-mentioned embodiment, but not limited thereto. The second augmented reality content may include augmented reality content generated based on the user input through the touch panel of the electronic device. For example, the second augmented reality content includes augmented reality content generated by the electronic device as the electronic device detects a touch input which is input on the area where the second image is displayed on the display of the electronic device.

In operation 307, the electronic device may display an animation effect of the first augmented reality content using the second augmented reality content based on the user input. According to an embodiment, the animation effect of the first augmented reality content using the second augmented reality content may include a graphic effect where a virtual object included in the first augmented reality content interacts with a virtual object included in the second augmented reality content. The animation effect of the first augmented reality content using the second augmented reality content may include, for example, a series of graphic effects indicating a process where at least one virtual object included in the first augmented reality content and the second augmented reality content is moved or where a shape or color of the at least one virtual object is changed.

According to an embodiment, the electronic device may receive a user input for displaying the animation effect of the first augmented reality content through the touch panel. The user input for displaying the animation effect of the first augmented reality content may include various touch inputs, for example, a tap or a double tap of the first augmented reality content or drag and drop for dragging and dropping the first augmented reality content onto a location adjacent to the second augmented reality content (e.g., into an area where the second image is displayed).

In this case, the processor 250 may display the animation effect of the first augmented reality content using the second augmented reality content based on distance information between the first augmented reality content and the second augmented reality content. For example, the distance between the first augmented reality content and the second augmented reality content is changed by at least one of a user input for moving the first augmented reality content input to the electronic device or a user input for moving the second augmented reality content input to the external electronic device. In this case, as it is determined that the distance between the first augmented reality content and the second augmented reality content is within a certain range, the electronic device may display the animation effect of the first augmented reality content using the second augmented reality content.

Hereinafter, a description will be given of a user interface for displaying an animation effect using pieces of a plurality of augmented reality content in the electronic device according to an embodiment with reference to FIGS. 4A and 4B.

FIGS. 4A and 4B are drawings illustrating a user interface provided by an electronic device according to various embodiments of the disclosure. Operations of the electronic device, which will be described below, may be performed by an electronic device 201 of FIG. 2 or a processor 250 of the electronic device 201.

Referring to FIGS. 4A and 4B, in drawings 400 and 450, the electronic device may receive a video call request from an external electronic device (e.g., an external electronic device 203 of FIG. 2) connected over a network (e.g., a network 202 of FIG. 2). The electronic device may receive the video call request from the external electronic device, thus displaying a first user interface 401 on a display (e.g., a display 230 of FIG. 2).

According to an embodiment, the first user interface 401 may include a user interface for receiving an acknowledgement to whether to accept/reject the video call request received from the external electronic device from a user. For example, the first user interface 401 includes a notification 410 for providing a notification of reception of the video call request and including information about a caller (e.g., Andy) who request a video call, a first button 411 to which an operation of establishing a video call connection is mapped, and a second button 412 to which an operation of blocking the video call connection is mapped. For example, the user selects the first button 411 for accepting a video call and may select the second button 412 for rejecting the video call.

The electronic device may receive the user input for selecting the first button 411, thus establishing a video call connection with the external electronic device. As the video call is connected with the external electronic device, the electronic device may display a second user interface 402 on its display.

According to an embodiment, the second user interface 402 may include a first image 421 captured by a camera (e.g., a camera 210 of FIG. 2) and a second image 422 received from the external electronic device. According to an embodiment, the second image 422 may include an image captured by a camera of the external electronic device. While the electronic device and the external electronic device make a video call connection with each other, the first image 421 and the second image 422 may be real-time images obtained by the cameras of the respective devices.

According to an embodiment, the electronic device may display first augmented reality content 431 on the first image 421 based on a user input using a stylus pen 425. The electronic device may detect a user input through its touch panel. For example, when the user draws a wine glass with wine on the first image 421 using the stylus pen 425, the electronic device generates and displays the first augmented reality content 431 in the shape of the wine glass with wine on the first image 421.

According to an embodiment, the electronic device may receive second augmented reality content 432 from the external electronic device. For example, when a user of the external electronic device draws a wine glass with wine on the second image 422 using a stylus pen, the external electronic device generates and transmits the second augmented reality content 432 in the shape of the wine glass with wine to the electronic device. The electronic device may display the second augmented reality content 432 received from the external electronic device on the second image 422.

The case where the first augmented reality content 431 is generated by the electronic device and the second augmented reality content 432 is generated by the external electronic device is exemplified in the above-mentioned embodiment, but not limited thereto. According to various embodiments, the first augmented reality content 431 may be generated by the external electronic device and may be transmitted to the electronic device based on a user input which is input through a touch panel corresponding to an area where the first image 421 is displayed on the display of the external electronic device. According to various embodiments, the second augmented reality content 432 may be generated based on a user input which is input through a touch panel corresponding to an area where the second image 422 is displayed on the display of the electronic device.

According to an embodiment, the electronic device may receive a user input for displaying an animation effect where the first augmented reality content 431 and the second augmented reality content 432 interact with each other through the touch panel. For example, the electronic device detects a touch input for tapping or double-tapping on the first augmented reality content 431 or the second augmented reality content 432 using the stylus pen 425, dragging and dropping the first augmented reality content 431 onto a location adjacent to the second augmented reality content 432, or dragging and dropping the second augmented reality content 432 onto a location adjacent to the first augmented reality content 431.

According to an embodiment, the electronic device may receive a specified user input through the touch panel, thus displaying a third user interface 403 on the display. According to an embodiment, the electronic device may display an animation effect using the first augmented reality content 431 and the second augmented reality content 432 on the third user interface 403.

According to an embodiment, the electronic device may receive a specified input for displaying an animation effect, thus identifying objects included in the first augmented reality content 431 and the second augmented reality content 432 and displaying an animation effect corresponding to the identified objects.

Referring to FIG. 4A, for example, when the user drags and drops the first augmented reality content 431 onto the location adjacent to the second augmented reality content 432 using the stylus pen 425, the electronic device identifies a pair of wine glasses as virtual objects included in the first augmented reality content 431 and the second augmented reality content 432 and may display an animation effect where the wine glass corresponding to the first augmented reality content 431 pours wine into the wine glass corresponding to the second augmented reality content 432.

Referring to FIG. 4B, for example, when the user double-taps the first augmented reality content 431 using the stylus pen 425, the electronic device identifies a pair of wine glasses as virtual objects included in the first augmented reality content 431 and the second augmented reality content 432 and displays an animation effect where the pair of wine glasses bump into each other to toast.

Referring to FIGS. 4A and 4B, the electronic device may display a first animation effect (e.g., pouring wine from one wine glass to another) by receiving a first user input (e.g., drag and drop) on the first augmented reality content 431 and the second augmented reality content 432 identified as the wine glasses and may display a second animation effect (e.g., making a toast with two wine glasses while the wine glasses bump into each other) by receiving a second user input (e.g., a double tap) of a type different from the first user input. In other words, the electronic device may display different animation effects depending on user inputs with respect to the same objects as the wine glasses. The electronic device may display an animation effect corresponding to a user input among at least one animation effect with respect to the same objects.

The virtual object identified from the first augmented reality content 431 and the virtual object identified from the second augmented reality content 432 are the same as each other in embodiments shown in FIGS. 4A and 4B, but not limited thereto. The virtual object identified from the first augmented reality content 431 and the virtual object identified from the second augmented reality content 432 may be different objects. For example, the first augmented reality content includes a bat and the second augmented reality content includes a ball. For example, the electronic device receives a user input for double-tapping the bat, thus displaying an animation effect where the ball is hit with the bat.

According to the above-mentioned embodiment, the electronic device may display an animation effect according to the at least one object included in the first augmented reality content 431 and the second augmented reality content 432 in response to a specified user input. According to an embodiment, the electronic device may identify at least one object included in the first augmented reality content 431 and the second augmented reality content 432 and may display an animation effect corresponding to the identified at least one object among animation effects specified according to the objects. For example, the animation effects specified according to the objects is stored in a memory (e.g., a memory 260 of FIG. 2) of the electronic device or an external server (e.g., a server 108 of FIG. 1) connected with the electronic device over the network. The electronic device may search for and display an animation effect corresponding to at least one object identified from the first augmented reality content 431 and the second augmented reality content 432 among the animation effects stored in the memory or the external server on the display.

Hereinafter, a description will be given of a method for providing augmented reality content in an electronic device according to an embodiment with reference to FIG. 5.

FIG. 5 is a flowchart illustrating an operation of an electronic device according to an embodiment of the disclosure. Operations of the electronic device, which will be described below, may be performed by an electronic device 201 of FIG. 2 or a processor 250 of the electronic device 201.

According to an embodiment, while the electronic device makes a video call connection with an external electronic device, it may perform a process shown in FIG. 5. According to an embodiment, the electronic device may perform the process shown in FIG. 5 after performing operation 301 and operation 303 shown in FIG. 3.

Referring to FIG. 5, in a method 500, in operation 501, the electronic device may identify a body part of a first user where first augmented reality content is displayed from a first image. According to an embodiment, the first image may include an image where a front camera or a rear camera of the electronic device captures the first user. The electronic device may identify the body part of the first user from the first image based on an object recognition technology. The object recognition technology may include a technology for identifying an object on an image or video and a location of the object using a deep-learning algorithm or a machine-learning algorithm. According to an embodiment, the electronic device may identify a body part of the first user from the first image and may identify a location of the identified body part of the first user on the first image.

According to the above, the electronic device may fix and display augmented reality content on an object or may fix and display the augmented reality content on a space. In the embodiment, it is assumed that the electronic device fixes and displays augmented reality content on a body part of the user, which is identified from the image.

According to an embodiment, the electronic device may identify a body part of the first user, which corresponds to a location where the first augmented reality content is displayed, based on a location of the body part of the first user, which is identified from the first image. For example, when a location where the first augmented reality content is displayed on the first image is a first location and when the first location is identified as a right cheek of the first user, the electronic device identifies a body part of the first user where the first augmented reality content is displayed as the right cheek.

In operation 503, the electronic device may identify a body part of a second user, which corresponds to the body part of the first user, from a second image. According to an embodiment, the second image may be an image received by the electronic device from an external electronic device through a communication circuit, which may include an image where a camera of the external electronic device captures the second user. According to an embodiment, the electronic device may identify a body part of the second user from the second image. Because the method for identifying the body part of the user from the image in the electronic device is described above in the description of operation 501, a duplicated description will be brief or omitted. According to an embodiment, the electronic device may identify a body part of the second user from the second image and may identify a location of the identified body part of the second user on the second image.

According to an embodiment, the electronic device may identify a body part of the second user, which corresponds to the body part of the first user, which is identified as operation 501 is performed, in the identified body part of the second user. According to an embodiment, the body part of the second user, which corresponds to the body part of the first user, may include the same body part as the body part of the first user. The electronic device may identify the same body part as the body part of the first user, which is identified as the location where the first augmented reality content is displayed as operation 501 is performed, from the second image, and may identify a location of the identified body part on the second image. For example, when identifying the body part of the first user where the first augmented reality content is displayed as a right cheek as operation 501 is performed, the electronic device identifies a location of the right cheek of the second user on the second image by performing operation 503.

In operation 505, the electronic device may display the first augmented reality content on the body part of the second user. According to an embodiment, the electronic device may display the first augmented reality content on the location of the body part of the second user on the second image, which is identified as operation 503 is performed.

Although not illustrated in FIG. 5, the electronic device according to an embodiment may transmit the first augmented reality content to the external electronic device. According to an embodiment, the electronic device may transmit the first image where the first augmented reality content is displayed to the external electronic device. For example, the electronic device may transmit location information where the first augmented reality content is displayed on the first image or body part information of the first user where the first augmented reality content is displayed to the external electronic device. According to an embodiment, the external electronic device may display the first augmented reality content on first image based on the location information or the body part information of the first user. The external electronic device may display the first augmented reality content on the location on the first image, which corresponds to the location information or the body part information of the first user.

According to an embodiment, the electronic device may generate and display the first augmented reality content on a specific body part of the first user based on the user input while making a video call connection with the external electronic device and may display the same augmented reality content (the first augmented reality content) on a location corresponding to the same body part as the specific body part of the first user on an image of another user (e.g., the second user) who are making a video call with the first user to allow a plurality of users to intuitively recognize that a visual expression is shared, thus improving user experience.

Hereinafter, a description will be given of a user interface where the electronic device according to an embodiment displays augmented reality content, which is generated based on a user input and is displayed on the first image, on a corresponding location of the second image with reference to FIG. 6.

Hereinafter, a description will be given of a user interface where the electronic device according to an embodiment displays augmented reality content, which is generated based on a user input, on the second image with reference to FIG. 7.

FIG. 7 is a drawing illustrating user interfaces provided by an electronic device and an external electronic device according to an embodiment of the disclosure. Operations of the electronic device, which will be described below, may be performed by an electronic device 201 of FIG. 2 or a processor 250 of the electronic device 201.

Referring to FIG. 7, in a drawing 700, the electronic device may receive a video call request from an external electronic device (e.g., an external electronic device 203 of FIG. 2) connected over a network (e.g., a network 202 of FIG. 2). The electronic device may receive video call requests from a plurality of external electronic devices, thus displaying a first user interface 701 on a display (e.g., a display 230 of FIG. 2).

According to an embodiment, the first user interface 701 may include a first image 721 captured by a camera (e.g., a camera 210 of FIG. 2) of the electronic device, a second image 722 received from a first external electronic device, a third image 723 received from a second external electronic device, a fourth image 724 received from a third external electronic device, and a fifth image 725 received from a fourth external electronic device. For example, the first image 721 is an image where the electronic device captures a first user (e.g., Jenny), the second image 722 may be an image where the first external electronic device captures a second user (e.g., Andy), the third image 723 may be an image where the second external electronic device captures a third user (e.g., Joy), the fourth image 724 may be an image where the third external electronic device captures a fourth user (e.g., James), and the fifth image 725 may be an image where the fourth external electronic device captures a fifth user (e.g., Sarah).

According to an embodiment, the electronic device may display augmented reality content on at least one of the first image 721, the second image 722, the third image 723, the fourth image 724, or the fifth image 725 based on a user input using a stylus pen 745. The electronic device may detect a user input through its touch panel. For example, when the user draws a hat on the second image 722 using the stylus pen 745, the electronic device generates and displays first augmented reality content 731 in the shape of the hat on the second image 722. Furthermore, when the user draws a ribbon on the third image 723 using the stylus pen 745, the electronic device may generate and display second augmented reality content 732 in the shape of the ribbon on the third image 723. Furthermore, when the user draws a heart on the fifth image 725 using the stylus pen 745, the electronic device may generate and display third augmented reality content 733 in the shape of the heart on the fifth image 725.

The case where the electronic device generates and displays pieces of augmented reality content for the second image 722, the third image 723, and the fifth image 725 on corresponding images in the above-mentioned embodiment is exemplified, but not limited thereto. The electronic device may generate and display each of pieces of augmented reality content based on a user input on each of images received from at least one external electronic device.

According to an embodiment, the electronic device may transmit augmented reality content generated for each image to the external electronic device over a network (e.g., a network 202 of FIG. 2). For example, the electronic device transmits first augmented reality content 731 generated for the second image 722, second augmented reality content 732 generated for the third image 723, and third augmented reality content 733 generated for the fifth image 725 to the external electronic device (e.g., first to fourth external electronic devices).

According to an embodiment, when the electronic device displays the first user interface 701, the first external electronic device may display a second user interface 702. The second user interface 702 may include the first to fifth images 721 to 725. According to an embodiment, the first external electronic device may display the second image 722 captured by the first external electronic device to be larger than the first image 721, the third image 723, the fourth image 724, and the fifth image 725.

According to an embodiment, the first external electronic device may display the first augmented reality content 731, the second augmented reality content 732, and the third augmented reality content 733 transmitted from the electronic device on corresponding images, respectively. For example, the first external electronic device displays the first augmented reality content 731 on the second image 722, displays the second augmented reality content 732 on the third image 723, and displays the third augmented reality content 733 on the fifth image 725.

According to an embodiment, the first external electronic device may adjust a size of augmented reality content to correspond to sizes of the first to fifth images 721 to 725. For example, the first external electronic device displays the second image 722 to be larger than the first image 721, the third image 723, the fourth image 724, and the fifth image 725, thus displaying the first augmented reality content 731 displayed on the second image 722 to be larger than the second augmented reality content 732 and the third augmented reality content 733. According to an embodiment, the first augmented reality content 731 displayed on the second image 722 by the first external electronic device may be larger in size than the first augmented reality content 731 when transmitted to the electronic device.

Referring to a second user interface 1102, the electronic device may deactivate a user interface for generating augmented reality content in a state where the proximity event or the touch event of the stylus pen 1145 is not detected. For example, in the state where the user interface for generating the augmented reality content is deactivated, the electronic device displays the first image 1121, the second image 1122, the third image 1123, the fourth image 1124, and the fifth image 1125 at the same size and fails to display the color selection element 1151 and the virtual pen selection element 1152.

According to an embodiment, the electronic device may receive an image selection input using the stylus pen 1145 through the touch panel, thus displaying a third user interface 1103 on the display. According to an embodiment, the image selection input may include an input where the user touches one of the first image 1121, the second image 1122, the third image 1123, the fourth image 1124, or the fifth image 1125 using the stylus pen 1145.

For example, the electronic device receives the user input for touching the second image 1122, thus displaying the third user interface 1103 on the display. Referring to the third user interface 1103, the electronic device may enlarge and display the second image 1122 and may display the color selection element 1151 and the virtual pen selection element 1152 at one side of the second image 1122.

The case where the electronic device activates the user interface for generating the augmented reality content based on whether the body part of the user or the stylus pen 1145 is close to the display is exemplified in the above-mentioned embodiment, but not limited thereto. The electronic device may control activation of a user interface for generating augmented reality content based on whether the stylus pen 1145 is mounted and demounted. For example, the electronic device may include a sensor capable of sensing mounting and demounting of the stylus pen 1145, may activate a user interface for generating augmented reality content by sensing the demounting of the stylus pen 1145 using the sensor, and may deactivate the user interface for generating the augmented reality content by sensing the mounting of the stylus pen 1145.

Hereinafter, a description will be given of a method for adding and display pieces of augmented reality content generated by different users in an electronic device according to an embodiment with reference to FIG. 12.

FIG. 12 is a drawing illustrating user interfaces provided by an electronic device and an external electronic device according to an embodiment of the disclosure.

Only one external electronic device (first external electronic device 1203) is illustrated in FIG. 12, but the electronic device 1201 may communicate with a plurality of external electronic devices to provide a multiparty video call service.

Referring to FIG. 12, in a drawing 1200, the electronic device 1201 may perform a video call with the plurality of external electronic devices. According to an embodiment, the electronic device 1201 may display a first image 1211 captured by a camera (e.g., a camera 210 of FIG. 2), a second image 1212 received from the first external electronic device 1203, a third image 1213 received from a second external electronic device, a fourth image 1214 received from a third external electronic device, and a fifth image 1215 received from a fourth external electronic device on a display (e.g., a display 230 of FIG. 2).

According to an embodiment, the electronic device 1201 may generate first augmented reality content 1217 based on a touch input using a stylus pen 1216 of a user, which is detected through a touch panel (e.g., a touch panel 220 of FIG. 2). For example, as a user provides an input on a display area where the first image 1211 is displayed, the electronic device 1201 maps first augmented reality content 1217 to a specific location on the first image 1211 and displays the first augmented reality content 1217 on the first image 1211.

According to an embodiment, the electronic device 1201 may identify a body part of the user where the first augmented reality content 1217 is displayed on the first image 1211. For example, the first to fifth images 1211 to 1215 includes a face of a user of the electronic device or the external electronic device. In the embodiment shown in FIG. 12, the electronic device 1201 may identify that the first augmented reality content 1217 in the shape of a heart is displayed on a left cheek of the user.

According to an embodiment, the electronic device 1201 may display the first augmented reality content 1217 at a corresponding location of an image except for the first image 1211 among a plurality of images based on the body part of the user where the first augmented reality content 1217 identified from the first image 1211 is displayed. For example, the electronic device 1201 identifies that the first augmented reality content 1217 is displayed on the left cheek of the user, thus displaying the first augmented reality content 1217 on the left cheek of each user identified from each of the second image 1212, the third image 1213, the fourth image 1214, and the fifth image 1215.

According to an embodiment, the electronic device 1201 may transmit the first augmented reality content 1217 to an external electronic device (e.g., the first external electronic device 1203) connected over the network. The electronic device 1201 may transmit location information where the first augmented reality content 1217 is displayed on the first image 1211 to the external electronic device (e.g., the first external electronic device 1203). The location information where the first augmented reality content 1217 is displayed on the first image 1211 may include, for example, body part information of the user where the first augmented reality content 1217 is displayed on the first image 1211.

According to an embodiment, the first external electronic device 1203 may display the first augmented reality content 1217 transmitted from the electronic device 1201 on the first to fifth images 1221 to 1225 displayed on a display of the first external electronic device 1203 based on the location information. According to the embodiment shown in FIG. 12, the first external electronic device 1203 may display the first augmented reality content 1217 on a left cheek of each user identified from each of the first to fifth images 1221 to 1225.

According to an embodiment, the first external electronic device 1203 may display a first image 1221 captured by a camera, a second image 1222 received from the electronic device 1201, a third image 1223 received from a second external electronic device, a fourth image 1224 received from a third external electronic device, and a fifth image 1225 received from a fourth external electronic device on its display.

According to an embodiment, the first external electronic device 1203 may generate second augmented reality content 1227 based on a touch input using a stylus pen 1226 of a user of the first external electronic device 1203, which is detected using the touch panel. For example, as the user provides an input on a display area where the first image 1221 is displayed, the first external electronic device 1203 maps the second augmented reality content 1227 to a specific location on the first image 1221 and displays the second augmented reality content 1227 on the first image 1221.

According to an embodiment, the first external electronic device 1203 may identify a body part of the user where the second augmented reality content 1227 is displayed on the first image 1221. In the embodiment shown in FIG. 12, the first external electronic device 1203 may identify that the second augmented reality content 1227 in the shape of a star is displayed on a right cheek of the user.

According to an embodiment, the first external electronic device 1203 may transmit the second augmented reality content 1227 to the electronic device 1201 connected over the network. The first external electronic device 1203 may transmit location information where the second augmented reality content 1227 is displayed on the first image 1211 to the electronic device 1201. The location information of the second augmented reality content 1227, which is received by the electronic device 1201, may include, for example, body part information of the user where the second augmented reality content 1227 is displayed on the first image 1221.

According to an embodiment, the electronic device 1201 may display the second augmented reality content 1227 on the first to fifth images 1211 to 1215 based on the location information of the second augmented reality content 1227. For example, the electronic device 1201 receives the location information that the second augmented reality content 1227 is displayed on the right cheek of the user, thus displaying the second augmented reality content 1227 on the right cheek of each user identified from each of the first to fifth images 1211 to 1215.

According to an embodiment, the electronic device 1201 may add and display the first augmented reality content 1217 generated by the user of the electronic device 1201 and the second augmented reality content 1227 generated by the user of the first external electronic device 1203 to each of a plurality of images. For the first to fifth images 1211 to 1215, the electronic device 1201 may display the first augmented reality content 1217 on a body part corresponding to the location information of the first augmented reality content 1217 among body parts of the user included in each image and may display the second augmented reality content 1227 on the body part corresponding to the location information of the second augmented reality content 1227.

According to an embodiment, the electronic device 1201 may display the first augmented reality content 1217 generated by the user of the electronic device 1201 and the second augmented reality content 1227 received from the first external electronic device 1203 in different colors to separately display pieces of augmented reality content generated by different users.

According to the above, the first external electronic device 1203 may display the second augmented reality content 1227 at a corresponding location of images (e.g., the second image 1222, the third image 1223, the fourth image 1224, and the fifth image 1225) except for the first image 1221 among the plurality of images based on the location information of the second augmented reality content 1227, which is identified from the first image 1221, and may display the first augmented reality content 1217 received from the electronic device 1201 at corresponding locations of the plurality of images (e.g., the first image 1221, the second image 1222, the third image 1223, the fourth image 1224, and the fifth image 1225) based on the location information.

Hereinafter, a description will be given of a method for providing a user interface associated with generating augmented reality content depending on a size of a display when the electronic device according to an embodiment includes a flexible display with reference to FIG. 13.

FIG. 13 is a drawing illustrating a user interface provided by an electronic device according to an embodiment of the disclosure. Operations of the electronic device, which will be described below, may be performed by an electronic device 201 of FIG. 2 or a processor 250 of the electronic device 201.

A display (e.g., a display 230 of FIG. 2) of the electronic device according to an embodiment, which is shown in FIG. 13, may include a flexible display. The flexible display may change in display size by, for example, a folding/unfolding operation or may change in display size by a rolling or sliding operation. According to an embodiment, the electronic device may detect a change in display size using a sensor module (e.g., a sensor module 176 of FIG. 1). The sensor module may sense a change in display size by sensing a folding, unfolding, rolling, or sliding operation of the display.

Referring to FIG. 13, in a drawing 1300, the electronic device may display a first user interface 1301 on the display as it is determined that the display size is less than a threshold and may display a second user interface 1302 or a third user interface 1303 on the display as it is determined that the display size is greater than or equal to the threshold.

For example, the electronic device includes a first display and a second display, which are arranged to face directions opposite to each other in a housing. When the second display is a foldable display, the electronic device may provide a user interface on the first display in a folding state and may provide a user interface on the second display in an unfolding state. According to an embodiment, the first display used in the folding state may be smaller than the second display used in the unfolding state. Thus, the electronic device may determine that the display decreases in size by sensing the folding operation using a sensor and may determine that the display increases in size by sensing the unfolding operation.

As another example, when the electronic device includes a rollable display, the electronic device provides a user interface on an enlarged screen in a rolling-out state and may provide a user interface on a reduced screen in a rolling-in state. The electronic device may determine that the display decreases in size by sensing the rolling-in operation using the sensor and may determine that the display increases in size by sensing the rolling-out operation.

According to an embodiment, as the video call is connected with a plurality of external electronic devices, the electronic device may display a first image 1321 captured by a camera (e.g., a camera 210 of FIG. 2) of the electronic device and a second image 1322, a third image 1323, a fourth image 1324, and a fifth image 1325 received from the plurality of external electronic devices on the display.

Referring to the first user interface 1301 and the second user interface 1302, the electronic device may increase sizes of the first to fifth images 1321 to 1325 as the display increases in size and may reduce the sizes of the first to fifth images 1321 to 1325 as the display decreases in size. According to an embodiment, the size of the image may refer to a size of a window where the image is displayed, which may include, for example, a horizontal length and a vertical length of the window or an area of the window. Furthermore, the electronic device may change the sizes of the first to fifth images 1325, thus changing layouts of the first to fifth images 1321 to 1325.

According to an embodiment, the electronic device may sense a proximity event or a touch event of a stylus pen 1345 to the display using the sensor, thus activating a user interface for generating augmented reality content. The user interface for generating the augmented reality content may include a color selection element 1351 and a virtual pen selection element 1352. Each element is described above with reference to FIG. 11, a duplicated description will be omitted.

Referring to the first user interface 1301 and the second user interface 1302, the electronic device may change at least one of a size and a layout of at least one element (e.g., the color selection element 1351 or the virtual pen selection element 1352) based on the change in display size. For example, the electronic device unfolds and displays a color palette of the color selection element 1351 and may and unfold and display a collection of pens of the virtual pen selection element 1352 as the display increases in size and may display the color selection element 1351 and the virtual pen selection element 1352 in a brief form as the display decreases in size.

According to an embodiment, when the stylus pen 1345 is away from the display in a state where the display size is greater than or equal to the threshold, the electronic device may display a third user interface 1303 on the display. According to the third user interface 1303, the electronic device may detect that the stylus pen 1345 is away from the display, thus deactivating a user interface for generating augmented reality content. For example, the electronic device ends the display of the color selection element 1351 and the virtual pen selection element 1352 and changes sizes and layouts of the first to fifth images 1321 to 1325.

According to the embodiment shown in FIG. 13, the electronic device may adjust a user interface to correspond to the size of the display to improve the user experience of the user in an augmented reality content providing environment of the electronic device including the display.
