The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one 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 module). Any of these communication modules may communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). For example, the wireless communication module (192) may use subscriber information stored in the subscriber identification module (e.g., an international mobile subscriber identity (IMSI)) to verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199).

According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) needs to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of executing the function or service itself or in addition, request one or more external electronic devices to execute at least a part of the function or service.

[0049] For example, an external electronic device (102) can render content data executed in an application and transmit it to the electronic device (101), and the electronic device (101) that receives the data can output the content data to the display module (160). If the electronic device (101) detects a user's movement through a sensor, the processor (120) of the electronic device (101) can correct the rendering data received from the external electronic device (102) based on the movement information and output it to the display module (160). Alternatively, the processor (120) of the electronic device (101) can transmit the movement information to the external electronic device (102) and request rendering so that the screen data is updated accordingly. According to an embodiment, the external electronic device (102) may be various types of devices, such as a smartphone or a case device that can store and charge the electronic device (101).

According to one embodiment, all or part of the operations executed by the electronic device (101) may be executed by one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) needs to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of executing the function or service itself or in addition, request one or more external electronic devices to execute at least a part of the function or service. The one or more external electronic devices that receive the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a part of a response to the request. For example, an external electronic device (102) renders content data executed in an application and transmits it to an electronic device (101), and the electronic device (101) that receives the data can output the content data to a display module (160). If the electronic device (101) detects user movement through an IMU sensor or the like, the processor of the electronic device (101) can correct the rendering data received from the external electronic device (102) based on the movement information and output it to the display module (160). Alternatively, the motion information can be transmitted to the external electronic device (102) to request rendering so that the screen data is updated accordingly.

[0058] According to one embodiment of the present disclosure, the display member (201) may include an optical waveguide (e.g., a waveguide). According to one embodiment of the present disclosure, an output image of an optical output module (211) incident on one end of the optical waveguide may be propagated inside the optical waveguide and provided to a user. According to one embodiment of the present disclosure, the optical waveguide may include at least one diffractive element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)) or at least one reflective element (e.g., a reflective mirror). For example, the optical waveguide may guide an output image of the optical output module (211) to a user's eye by using at least one diffractive element or reflective element.

[0059] For example, a waveguide serves to transmit the light generated by the display to the user's eyes.

[0060] The optical waveguide may be made of glass, plastic, or polymer, and may include nano-patterns formed on a portion of the inner or outer surface, for example, a grating structure having a polygonal or curved shape. According to one embodiment, light incident on one end of the waveguide may be propagated within the display optical waveguide by the nano-patterns and provided to a user. In addition, an optical waveguide composed of a free-form prism may provide the incident light to a user through a reflective mirror. The optical waveguide may include at least one diffractive element (e.g., a Diffractive Optical Element (DOE), a Holographic Optical Element (HOE)) or at least one reflective element (e.g., a reflective mirror). The optical waveguide may guide display light emitted from a light source unit to a user's eye by using at least one diffractive element or reflective element included in the optical waveguide.

[0061] According to various embodiments, the diffractive element may include an input optical member / output optical member (not shown). For example, the input optical member may mean an input grating area, and the output optical member (not shown) may mean an output grating area. The input grating area may serve as an input terminal that diffracts (or reflects) light output from (e.g., a Micro LED) to transmit the light to a transparent member (e.g., a first transparent member, a second transparent member) of a screen display unit. The output grating area may serve as an outlet that diffracts (or reflects) light transmitted to a transparent member (e.g., a first transparent member, a second transparent member) of a waveguide to a user's eye.

[0062] According to various embodiments, the reflective element may include a total internal reflection (TIR) ​​optical element or a total internal reflection waveguide. For example, total internal reflection may refer to a method of guiding light such that light (e.g., a virtual image) entering through an input grating region is 100% reflected from one surface (e.g., a specific surface) of the waveguide, thereby transmitting 100% of the light to the output grating region.

[0063] In one embodiment, light emitted from a display can be guided along an optical path through an input optical element into a waveguide. Light traveling within the waveguide can be guided toward the user's eyes through an output optical element. The screen display can be determined based on the light emitted toward the user's eyes.

[0064] According to one embodiment of the present disclosure, the camera module (250) can capture still images and / or moving images. According to one embodiment, the camera module (250) is disposed within a lens frame and can be disposed around the display member (201).

[0065] According to one embodiment of the present disclosure, the first camera module (251) can capture and / or recognize the trajectory of the user's eye (e.g., pupil, iris) or gaze. According to one embodiment of the present disclosure, the first camera module (251) can periodically or aperiodically transmit information related to the trajectory of the user's eye or gaze (e.g., trajectory information) to a processor (e.g., processor (120) of FIG. 1).

[0066] For example, the first camera module (e.g., ET (Eye Tracking) camera) can be used to detect and track the pupil. The first camera module (251) can be used to position the center of the virtual image projected on the AR glasses according to the direction in which the pupil of the AR glasses wearer is looking. The first camera module (251) can include a GS camera to detect the pupil and track rapid eye movement. The first camera module (251) (e.g., ET camera) can be installed for the left eye and the right eye, respectively, and the same camera performance and specifications can be used for each.

[0067] According to one embodiment of the present disclosure, the second camera module (253) can capture an external image.

[0068] For example, the second camera module (253) can capture HR (High Resolution) or PV (Photo Video) images and can use a high-resolution camera. The second camera module (253) can include a color camera equipped with functions for obtaining high-quality images, such as an AF function and optical image stabilization (OIS). The second camera module (253) can include the use of a GS camera or an RS camera.

[0069] According to one embodiment of the present disclosure, the third camera module (255) can be used for hand detection and tracking, and user gesture (e.g., hand movement) recognition. According to one embodiment of the present disclosure, the third camera module (255) can be used for 3 degrees of freedom (3DoF), 6DoF head tracking, position (space, environment) recognition, and / or movement recognition. According to one embodiment of the present disclosure, the second camera module (253) can also be used for hand detection and tracking, and user gesture recognition. According to one embodiment of the present disclosure, at least one of the first camera module (251) to the third camera module (255) can be replaced with a sensor module (e.g., a LiDAR sensor). For example, the sensor module can include at least one of a vertical cavity surface emitting laser (VCSEL), an infrared sensor, and / or a photodiode.

[0070] For example, the third camera module (255) is a camera used for 3DoF, 6DoF head tracking, hand detection and tracking, and spatial recognition, and may include a GS (Global shutter) camera. Since a stereo camera is required for head tracking and spatial recognition, the third camera module (255) may include two or more GS cameras. The third camera module (255) may use a GS camera, which has superior performance (image drag) compared to a RS (Rolling shutter) camera, to detect and track fine movements such as rapid hand movements and fingers. The third camera module (255) may perform spatial recognition for 6DoF, and a SLAM function through depth shooting. In addition, it may perform a user gesture recognition function.

[0071] For example, the wearable electronic device (200) may include a fourth camera module. The fourth camera module may include a face tracking (FT) camera. The fourth camera module may detect and track a user's facial expressions.

[0072] For example, a wearable electronic device (200) may include an illumination module (or LED). The illumination module may be used for various purposes depending on the location where it is attached. As an example, an illumination module attached around the AR glasses frame may be used as an auxiliary means to facilitate gaze detection when tracking eye movements with an ET camera, and may include an IR LED of an infrared wavelength.

[0073] As a practical example, the light emitting unit can be attached adjacent to a camera, such as around a hinge connecting a frame and a temple, or around a bridge connecting frames, to supplement ambient brightness when taking pictures, and can be used when subject detection is not easy in a dark environment.

[0074] For example, the wearable electronic device (200) may include a printed circuit board (PCB). The printed circuit board may be disposed on the temple portion of the glasses and may transmit electrical signals to each module (Camera, Display, Audio, Sensor) and other printed circuit boards through the FPCB. According to various embodiments, at least one printed circuit board may include a first substrate, a second substrate, and an interposer disposed between the first substrate and the second substrate.

[0075] For example, a printed circuit board can be placed in the center of the set, and electrical signals can be transmitted to each module (e.g., Camera, Display, Audio, Sensor) and other printed circuit boards through the FPCB.

[0076]

[0077] FIGS. 3A and 3B are drawings showing the front and back of a wearable electronic device (300) according to one embodiment.

[0078] Referring to FIGS. 3A and 3B, in one embodiment, camera modules (311, 312, 313, 314, 315, 316) and / or depth sensors (317) for obtaining information related to the surrounding environment of the wearable electronic device (300) may be arranged on the first surface (310) of the housing.

[0079] In one embodiment, the camera modules (311, 312) can acquire images related to the environment surrounding the wearable electronic device.

[0080] In one embodiment, the camera modules (313, 314, 315, 316) can acquire images while the wearable electronic device is worn by a user. The camera modules (313, 314, 315, 316) can be used for hand detection and tracking, and user gesture (e.g., hand movement) recognition. The camera modules (313, 314, 315, 316) can be used for 3DoF, 6DoF head tracking, position (spatial, environmental) recognition, and / or movement recognition. In one embodiment, the camera modules (311, 312) can also be used for hand detection and tracking, and user gesture.

[0081] In one embodiment, a depth sensor (317) may be configured to transmit a signal and receive a signal reflected from a subject, and may be used for purposes such as time of flight (TOF) to determine the distance to an object. Instead of or in addition to the depth sensor (317), the camera modules (213, 214, 215, 216) may determine the distance to an object.

[0082] For example, a depth sensor (317) can be used to determine the distance to an object, such as with TOF. TOF (Time of Flight) is a technology that measures the distance to an object using signals (near-infrared, ultrasound, laser, etc.). TOF technology emits a signal from a transmitter, and measures the signal's flight time at a receiver.

[0083] According to one embodiment, a camera module (325, 326) for facial recognition and / or a display (321) (and / or a lens) may be disposed on the second side (320) of the housing.

[0084] In one embodiment, a face recognition camera module (325, 326) adjacent to the display may be used to recognize a user's face, or may recognize and / or track both eyes of the user.

[0085] In one embodiment, the display (321) (and / or lens) may be disposed on the second side (320) of the wearable electronic device (300). In one embodiment, the wearable electronic device (300) may not include camera modules (315, 316) among the plurality of camera modules (313, 314, 315, 316). Although not illustrated in FIGS. 3A and 3B , the wearable electronic device (300) may further include at least one of the configurations illustrated in FIG. 2 .

[0086] As described above, according to one embodiment, the wearable electronic device (300) may have a form factor for being worn on a user's head. The wearable electronic device (300) may further include a strap and / or a wearing member for being secured to a body part of the user. The wearable electronic device (300) may provide a user experience based on augmented reality, virtual reality, and / or mixed reality while being worn on the user's head.

[0087]

[0088] Figure 4 is a flowchart of an operation of a voice signal processing method according to various embodiments.

[0089] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0090] For example, an embodiment in which operation (420) is performed after operation (410) in FIG. 4 is described, but is not limited thereto. According to various embodiments, an electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (101) of FIG. 2, wearable electronic device (101) of FIG. 3) may perform operation (410) after operation (420), or may perform operations (410) and (420) in parallel.

[0091] According to one embodiment, operations (410) to (490) may be understood to be performed in a processor of an electronic device (101) (e.g., processor (120) of FIG. 1).

[0092] For example, the electronic device (101) can control the display module (160) to display a first virtual object according to a first application based on a real environment or a virtual environment acquired using a sensor (e.g., the camera module (180) of FIG. 1, the camera module (250) of FIG. 2, the second camera module (253)) in operation (410).

[0093] For example, the electronic device (101) can acquire a real environment using a camera in an augmented reality (AR) mode. The electronic device (101) can control a display module (e.g., the display module (160) of FIG. 1, the light output module (211) of FIG. 2) to display a first virtual object according to a first application based on the real environment in the AR mode.

[0094] For example, in a VR (virtual reality) mode, the electronic device (101) can control the display module (160) to display a first virtual object according to a first application based on a virtual environment.

[0095] For example, AR mode may refer to an operation mode that controls the display module (160) to display a virtual object in a real environment. For example, VR mode may refer to an operation mode that controls the display module (160) to display a virtual object in a virtual environment.

[0096] For example, the first application may include an application for transmitting a first voice signal to an external electronic device. For example, the first application may include a calling application or a conference application. For example, the first virtual object according to the first application may include virtual objects related to a call partner or a conference participant.

[0097] For example, the electronic device (101) can control the display module (160) to display a second virtual object according to a second application in an area that does not overlap with an area where a first virtual object is displayed, based on a real environment or a virtual environment in operation (420).

[0098] For example, when a first virtual object is displayed in the entire area of ​​the display module (160), the electronic device (101) can display a second virtual object in an area overlapping the area where the first virtual object is displayed.

[0099] For example, the second application may include an application that provides the results of processing the first voice signal. For example, the second application may include an application related to an AI assistant. The AI ​​assistant application may represent an application that processes voice commands received from the user and provides the results of the voice command processing. The second application may provide the results of the voice command processing to the user through a second virtual object.

[0100] For example, the electronic device (101) can obtain the user's gaze information by using a sensor (e.g., the camera module (180) of FIG. 1, the camera module (250) of FIG. 2) in operation (430). The electronic device (101) can determine an area corresponding to the user's gaze information in the display module (160). For example, the electronic device (101) can identify an area of ​​the display module (160) that the user is looking at based on the gaze information.

[0101] For example, the electronic device (101) may receive a first voice signal using an audio input module (e.g., input module (150) of FIG. 1, microphone) in operation (440). For example, the first voice signal may include a voice signal received from a user.

[0102] For example, the electronic device (101) can determine whether the second virtual object corresponds to the gaze information in operation (450).

[0103] For example, the electronic device (101) may determine that the second virtual object corresponds to the user's gaze information when the user's gaze direction corresponds to an area of ​​the display module (160) where the second virtual object is displayed for a set period of time or longer.

[0104] For example, if it is determined that the second virtual object corresponds to the gaze information in operation (450), the electronic device (101) can control the second application to process the first voice signal in operation (460).

[0105] For example, the electronic device (101) can control the display module (160) to display the result of processing the first voice signal in operation (470) through a second virtual object.

[0106] For example, in operation (470), the electronic device (101) can provide the result of processing the first voice signal to the user through a second virtual object (e.g., displaying it on a display module (160), outputting an audio signal through an audio output device (e.g., audio output device (155) of FIG. 1)).

[0107] The electronic device (101) can control the first application to stop processing the first voice signal if it is determined that the second virtual object corresponds to the gaze information.

[0108] For example, if it is determined that the second virtual object corresponds to the gaze information in operation (450), the electronic device (101) can control the first application to process the first voice signal in operation (480).

[0109] For example, the electronic device (101) can transmit a first audio signal to an external electronic device in operation (490).

[0110] The first application and the second application can commonly process the first voice signal. When the first application and the second application are running simultaneously, the electronic device (101) can determine which application will process the first voice signal based on the user's gaze information, according to the user's intention.

[0111] When a user looks at a first virtual object, for example, if the first virtual object corresponds to the user's gaze information, the received first voice signal can be processed by the first application. The first voice signal processed by the first application can be transmitted to an external electronic device. In this case, the electronic device (101) can control the second application so that the first voice signal is not processed by the second application.

[0112] When a user looks at a second virtual object, for example, if the second virtual object corresponds to the user's gaze information, the received first voice signal may be processed by the second application. The result of processing the first voice signal processed by the second application may be provided to the user through the second virtual object (e.g., displayed on a display module (160), outputting an audio signal through an audio output device (e.g., an audio output device (155) of FIG. 1)). At this time, the electronic device (101) may control the first application so that the first voice signal is not processed by the first application.

[0113] For example, the electronic device (101) may prevent the first voice signal from being input to the first application, stop the first application from processing the first voice signal, or stop transmitting the processed first voice signal to the external electronic device.

[0114] For example, the electronic device (101) may display a virtual object (e.g., an icon indicating mute, a virtual object indicating mute) on the display module (160) to indicate that the first voice signal is not input to the first application, the first application has stopped processing the first voice signal, or has stopped transmitting the processed first voice signal to the external electronic device.

[0115]

[0116] FIGS. 5A, 5B, and 5C are diagrams illustrating operations of an electronic device (e.g., an electronic device (101) of FIG. 1, a wearable electronic device (200) of FIG. 2, and a wearable electronic device (300) of FIG. 3) processing a voice signal according to various embodiments.

[0117] FIG. 5A is a drawing showing an example in which a user (510) looks at a display module (e.g., display module (160) of FIG. 1, light output module (211) of FIG. 2) on which a first virtual object (520, 521, 522) for a first application and a second virtual object (530) for a second application are displayed.

[0118] FIG. 5b is a diagram illustrating an example in which the first gaze information (541) of a user (510) corresponds to the first virtual object (520, 521, 522). In FIG. 5b, the first virtual object (520, 521, 522) for the first application and the second virtual object (530) for the second application may be displayed on the display module (160).

[0119] In FIG. 5B, the electronic device (101) can control the first application to process the first voice signal based on the first gaze information (541) of the user (510). For example, the electronic device (101) can determine that the first virtual objects (520, 521, 522) in FIG. 5B correspond to the first gaze information (541).

[0120] For example, the electronic device (101) can process the first gaze information (541) to determine the first gaze direction (551) of the user (510). Based on the first gaze direction (551) (or the first gaze information (541)), the electronic device (101) can determine that the first virtual object (521) corresponds to the first gaze direction (551) (or the first gaze information (541)).

[0121] When the first virtual object (521) corresponds to the first gaze direction (551) (or the first gaze information (541)), the electronic device (101) can determine the first application as the application to process the first voice signal.

[0122] In FIG. 5b, the electronic device (101) can convert and / or process the first voice signal into a signal for transmission to an external electronic device.

[0123] FIG. 5C is a diagram illustrating an example in which the second gaze information (542) of a user (510) corresponds to a second virtual object (530). In FIG. 5C, a first virtual object (520, 521, 522) for a first application and a second virtual object (530) for a second application may be displayed on the display module (160).

[0124] In FIG. 5C, the electronic device (101) can control the second application to process the first voice signal based on the second gaze information (542) of the user (510). For example, the electronic device (101) can determine that the second virtual object (530) in FIG. 5C corresponds to the second gaze information (542). For example, the electronic device (101) can process the second gaze information (542) to determine the second gaze direction (552) of the user (510). Based on the second gaze direction (552) (or the second gaze information (542)), the electronic device (101) can determine that the second virtual object (530) corresponds to the second gaze direction (552) (or the first gaze information (542)).

[0125] If the second virtual object (530) corresponds to the second gaze direction (552) (or the first gaze information (542)), the electronic device (101) can determine the second application as the application to process the first voice signal.

[0126] In FIG. 5C, the electronic device (101) can process the first voice signal using a second application. For example, if the second application is an AI assistant, the electronic device (101) can perform voice recognition using the first voice signal and provide a result based on the voice recognition result.

[0127] In FIG. 5c, the electronic device (101) can control the first application so that the first application does not process the first voice signal based on the first gaze information (542) of the user (510).

[0128] Referring to FIGS. 5b and 5c, the electronic device (101) can control the second application so that the second application does not process the first voice signal based on the first gaze information (541) of the user (510).

[0129] For example, the electronic device (101) may determine the transparency and / or appearance (e.g., color, shape, size) of the second virtual object (530) based on the gaze information. For example, as shown in FIG. 5b, if the first gaze information (541) corresponds to the first virtual object (521, 522, 523), the electronic device (101) may increase the transparency of the second virtual object. For example, as shown in FIG. 5c, if the second gaze information (542) corresponds to the second virtual object (530), the electronic device (101) may decrease the transparency of the second virtual object.

[0130] For example, if the gaze information corresponds to the first virtual object (521, 522, 523), the electronic device (101) can reduce the size of the second virtual object. For example, if the gaze information corresponds to the second virtual object (530), the electronic device (101) can increase the size of the second virtual object.

[0131] For example, if the user's gaze information does not correspond to the first virtual object and the second virtual object, the electronic device (101) can process the first voice signal using the set application.

[0132] For example, if the set application is the first application and the gaze information does not correspond to the first virtual object and the second virtual object, the electronic device (101) can transmit the first voice signal to the external electronic device using the first application.

[0133] For example, if the set application is a second application and the gaze information does not correspond to the first virtual object and the second virtual object, the electronic device (101) can process the first voice signal using the second application.

[0134]

[0135] FIG. 6 is a flowchart illustrating an operation of an electronic device (101) (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (101) of FIG. 2, the wearable electronic device (101) of FIG. 3) processing a second voice signal according to various embodiments.

[0136] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0137] According to one embodiment, operations (610) to (640) may be understood to be performed in a processor of an electronic device (101) (e.g., processor (120) of FIG. 1).

[0138] For example, after operation (440) of FIG. 4, the electronic device (101) can receive a second voice signal from an external electronic device using the first application in operation (610).

[0139] For example, the electronic device (101) can determine whether the second virtual object corresponds to the gaze information in operation (620). With respect to operation (620), the description of operation (450) of FIG. 4 can be substantially equally applied.

[0140] For example, if it is determined that the second virtual object corresponds to the gaze information in operation (620), the electronic device (101) can control the display module (e.g., the display module (160) of FIG. 1, the light output module (211) of FIG. 2) to display character information corresponding to the second voice signal in operation (630).

[0141] For example, the electronic device (101) can convert the second voice signal into text information. The electronic device (101) can display the converted text information on the display module (160). When a plurality of first virtual objects corresponding to a plurality of external electronic devices that are communicably connected to the electronic device (101) are displayed on the display module (160), the electronic device (101) can control the display module (160) to display the text information based on the first virtual objects corresponding to the external electronic devices that have received the second voice signal.

[0142] For example, if it is determined in operation (620) that the second virtual object does not correspond to the gaze information (or if it is determined that the first virtual object corresponds to the gaze information), the electronic device (101) may output a second audio signal using an audio output module (e.g., the audio output module (155) of FIG. 1) in operation (630).

[0143]

[0144] FIG. 7 is a diagram illustrating an operation of an electronic device (101) (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (101) of FIG. 2, the wearable electronic device (101) of FIG. 3) according to various embodiments to display character information corresponding to a second voice signal.

[0145] FIG. 7 is a diagram illustrating an example in which a user (710) looks at a display module (e.g., display module (160) of FIG. 1, light output module (211) of FIG. 2) on which a first virtual object (720, 721, 722) for a first application and a second virtual object (730) for a second application are displayed. In FIG. 7, the second virtual object may correspond to the gaze information (742) of the user (710).

[0146] In FIG. 7, the electronic device (101) can convert a second voice signal received from an external electronic device into text information (723). The electronic device (101) can display the converted text information (723) on a display module (160).

[0147] In FIG. 7, when a second voice signal is received from an external electronic device corresponding to a first virtual object (720), the electronic device (101) can display character information (723) on the display module (160) corresponding to the first virtual object (720).

[0148]

[0149] FIG. 8 is a flowchart illustrating an operation of an electronic device (101) (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (101) of FIG. 2, and the wearable electronic device (101) of FIG. 3) processing facial information according to various embodiments.

[0150] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0151] According to one embodiment, operations (810) to (870) may be understood to be performed in a processor of an electronic device (101) (e.g., processor (120) of FIG. 1).

[0152] For example, after operation (440) of FIG. 4, the electronic device (101) can obtain the user's face information by using a sensor (e.g., camera module (180) of FIG. 1, camera module (250) of FIG. 2, depth sensor (317) of FIGS. 3A and 3B, LIDAR, FT camera) in operation (810).

[0153] The electronic device (101) can transmit an image to an external electronic device. For example, the image may include a character or avatar set in relation to the user. The electronic device (101) can transmit an image reflecting facial information (e.g., facial expression, eye / nose / mouth movements) acquired using sensors (180, 250) or an image not reflecting facial information to the external electronic device.

[0154] For example, the electronic device (101) can determine whether the second virtual object corresponds to the gaze information in operation (820).

[0155] For example, if it is determined in operation (820) that the second virtual object corresponds to the gaze information, the electronic device (101) can determine in operation (830) whether the first voice signal was received from the user.

[0156] For example, if it is determined in operation (830) that the first voice signal was received from the user, the electronic device (101) may transmit an image that does not reflect facial information to an external electronic device in operation (840). The electronic device (101) may determine the speaker of the received first voice signal. For example, the electronic device (101) may distinguish the speaker of the voice signal through various known methods. The electronic device (101) may determine whether the speaker of the first voice signal is the user wearing the electronic device (101).

[0157] For example, the electronic device (101) may transmit an initially set image to an external electronic device. The electronic device (101) may transmit an image reflecting facial information at a set point in time to the external electronic device. For example, the set point in time may indicate a point in time when the user's gaze information is determined to correspond to a second virtual object.

[0158] For example, if the user's gaze information does not correspond to the first virtual object for a set period of time (or if the user's gaze information corresponds to the second virtual object), the electronic device (101) may transmit a plurality of initially set images to the external electronic device in a set order or in a random order. For example, the electronic device (101) may transmit a plurality of initially set images to the external electronic device in a set order or in a random order at set intervals.

[0159] For example, if it is determined that the first voice signal is not received from the user in operation (830), the electronic device (101) may perform an operation according to operation (440) of FIG. 4.

[0160] For example, if it is determined in operation (820) that the second virtual object does not correspond to the gaze information, the electronic device (101) can determine in operation (850) whether the first virtual object corresponds to the gaze information.

[0161] For example, if it is determined in operation (850) that the first virtual object corresponds to the gaze information, the electronic device (101) can determine whether the first voice signal has been received from the user in operation (860). With respect to operation (860), the description regarding operation (830) may be substantially identically applied.

[0162] For example, if it is determined that the first voice signal was received from the user in operation (860), the electronic device (101) can transmit an image reflecting facial information to an external electronic device in operation (870).

[0163] For example, if it is determined in operation (850) that the first virtual object does not correspond to the gaze information, the electronic device (101) may perform an operation according to operation (440) of FIG. 4.

[0164] For example, if it is determined that the first voice signal is not received from the user in operation (860), the electronic device (101) may perform an operation according to operation (440) of FIG. 4.
