Description

Method and device for creating and placing virtual objects corresponding to real objects

[0001] Embodiments disclose techniques relating to methods and / or systems for creating and placing virtual objects corresponding to real objects.

[0002] Recently, virtual reality (VR), augmented reality (AR), and mixed reality (MR) technologies, which utilize computer graphics technology, are being developed. VR technology uses computers to create virtual spaces that don't exist in the real world and then make them feel real, while AR or MR technologies superimpose computer-generated information on top of the real world. In other words, they combine the real and virtual worlds to enable real-time user interaction.

[0003] Among these, AR and MR technologies are being integrated and utilized in various fields, such as broadcasting, medical technology, and gaming technology. Representative examples of AR being integrated into broadcasting include the natural change of weather maps in front of a weathercaster giving a weather forecast on TV, or the insertion of non-existent advertising images into the stadium during a sports broadcast, making them appear as if they were actually there.

[0004] A representative service that provides users with augmented reality or mixed reality is the metaverse. This metaverse, a portmanteau of "meta," meaning "fictional" or "abstract," and "universe," signifying the real world, refers to a three-dimensional virtual world. A more advanced concept than the existing term "virtual reality environment," the metaverse provides an augmented reality environment where virtual worlds like the web and the internet are integrated into the real world.

[0005] An electronic device according to one embodiment may include a camera for photographing a real space, a communication circuit, a memory storing computer-executable instructions, and at least one processor for accessing the memory and executing the instructions. The processor(s) and / or instructions, when the instructions are executed, may cause the processor(s) to acquire a real space image using the camera, identify an external object from the acquired real space image, determine an object of interest among the identified external objects based on a configuration for a virtual space, and place a virtual object corresponding to the determined object of interest in the virtual space.

[0006] A method performed by an electronic device according to one embodiment may include the steps of obtaining a real space image using a camera, identifying an external object from the obtained real space image, determining an object of interest among the identified external objects based on a configuration for a virtual space, and placing a virtual object corresponding to the determined object of interest in the virtual space.

[0024] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0025] The memory (130) can store various data used by at least one component (e.g., processor (120) or sensor module (176)) of the electronic device (101). The data can include, for example, software (e.g., program (140)) and input data or output data for commands related thereto. The memory (130) can include volatile memory (132) or non-volatile memory (134).

[0027] The input module (150) can receive commands or data to be used in a component of the electronic device (101) (e.g., a processor (120)) from an external source (e.g., a user) of the electronic device (101). The input module (150) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0028] The audio output module (155) can output audio signals to the outside of the electronic device (101). The audio output module (155) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0029] A display module (160) (e.g., a display) can visually provide information to an external device (e.g., a user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0030] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0031] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0032] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)).

[0037] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0038] The communication module (190) includes a communication circuit and may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. 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). Among these communication modules, the corresponding communication module can 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 can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0039] The wireless communication module (192) includes a communication circuit and can support a 5G network and next-generation communication technologies following a 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can 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 one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0040] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0041] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0042] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0043] According to one embodiment, commands or data can be transmitted or received between an electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199).

[0044] Each of the external electronic devices (102, 104) and the server (108) may be the same type of device as or different from 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 the server (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. In this specification, an example is mainly described in which an electronic device (101) is an augmented reality device (e.g., an electronic device (201) of FIG. 2, an electronic device (301) of FIG. 3, or an electronic device (401) of FIGS. 4A and 4B), and an external electronic device (102, 104) or a server (108) among the servers transmits the results of executing a virtual space and additional functions or services related to the virtual space to the electronic device (101).

[0045] The server (108) may include a processor (181), a communication module (182) including a communication circuit, and a memory (183). The processor (181), the communication module (182), and the memory (183) may be configured similarly to the processor (120), the communication module (190), and the memory (130) of the electronic device (101). For example, the processor (181) may provide a virtual space and interaction between users within the virtual space by executing instructions stored in the memory (183). The processor (181) may generate at least one of visual information, auditory information, or tactile information of the virtual space and an object within the virtual space. For example, as visual information, the processor (181) may generate rendering data (e.g., visual rendering data) that renders the appearance (e.g., shape, size, color, or texture) of the virtual space and the appearance (e.g., shape, size, color, or texture) of an object positioned within the virtual space. In addition, the processor (181) may generate rendering data that renders a change (e.g., a change in the appearance of an object, a sound generation, or a tactile generation) based on at least one of an interaction between objects (e.g., a physical object, a virtual object, or an avatar object) in a virtual space, or a user input to an object (e.g., a physical object, a virtual object, or an avatar object). The communication module (182) may establish communication with a first electronic device (e.g., an electronic device (101)) of a user and a second electronic device (e.g., an electronic device (102)) of another user. The communication module (182) may transmit at least one of the visual information, the tactile information, or the auditory information described above to the first electronic device and the second electronic device. For example, the communication module (182) may transmit rendering data.

[0046] For example, the server (108) renders content data executed in an application and transmits it to the electronic device (101), and the electronic device (101) receiving the data can output the content data to the display module (160). If the electronic device (101) detects user movement through an IMU sensor or the like, 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 movement information can be transmitted to the server (108) to request rendering so that the screen data is updated accordingly. However, the present invention is not limited thereto, and the aforementioned rendering can be performed by various forms of external electronic devices (102, 104), such as a smartphone or a case device capable of storing and charging the electronic device (101). Rendering data corresponding to the aforementioned virtual space generated by the external electronic device (102, 104) can be provided to the electronic device (101). For another example, the electronic device (101) may receive virtual space information (e.g., vertex coordinates, texture, color defining the virtual space) and object information (e.g., vertex coordinates, texture, color defining the appearance of an object) from the server (108) and perform rendering on its own based on the received data.

[0047] Each “processor” herein may include processing circuitry and / or may include multiple processors. For example, as used herein, including in the claims, the term “processor” may include various processing circuitry including at least one processor, one or more of which may be configured to perform various functions described herein, either individually or collectively in a distributed manner. As used herein, when “processor,” “at least one processor,” and “one or more processors” are described as being configured to perform numerous functions, these terms cover, by way of example and not limitation, situations where one processor performs some of the recited functions and other processor(s) perform other of the recited functions. Additionally, the at least one processor may include a combination of processors that perform various of the recited / disclosed functions, e.g., in a distributed manner. The at least one processor may execute program instructions to perform or accomplish various functions.

[0048] FIG. 2 illustrates an example of an optical see-through device according to various embodiments.

[0049] The electronic device (201) may include at least one of a display (e.g., a display module (160) of FIG. 1), a vision sensor, a light source (230a, 230b), an optical element, or a substrate. An electronic device (201) that has a transparent display and provides an image through the transparent display may be referred to as an optical see-through device (OST device).

[0050] The display may include, for example, a liquid crystal display (LCD), a digital mirror device (DMD), a liquid crystal on silicon (LCoS), an organic light emitting diode (OLED), or a micro light emitting diode (micro LED).

[0051] In one embodiment, when the display is formed of one of a liquid crystal display, a digital mirror display, or a silicon liquid crystal display, the electronic device (201) may include a light source (230a, 230b) that irradiates light to a screen output area (e.g., a screen display unit (215a, 215b)) of the display. In another embodiment, when the display can generate light on its own, for example, when it is formed of one of an organic light emitting diode or a micro LED, the electronic device (201) may provide a good quality virtual image to the user even without including a separate light source (230a, 230b). In one embodiment, when the display is implemented with an organic light emitting diode or a micro LED, the light source (230a, 230b) is unnecessary, and thus the electronic device (201) may be lightweight.

[0052] Referring to FIG. 2, the electronic device (201) may include a display, a first transparent member (225a) and / or a second transparent member (225b), and a user may use the electronic device (201) while wearing it on his or her face. The first transparent member (225a) and / or the second transparent member (225b) may be formed of a glass plate, a plastic plate, or a polymer, and may be manufactured to be transparent or translucent. According to one embodiment, the first transparent member (225a) may be arranged to face the user's right eye, and the second transparent member (225b) may be arranged to face the user's left eye. The display may include a first display (205) that outputs a first image (e.g., a right image) corresponding to the first transparent member (225a), and a second display (210) that outputs a second image (e.g., a left image) corresponding to the second transparent member (225b). In one embodiment, if each display is transparent, each display and transparent member may be positioned at a position facing the user's eyes to form a screen display unit (215a, 215b).

[0053] In one embodiment, light emitted from the display (205, 210) may be guided along an optical path through an input optical member (220a, 220b) into a waveguide. Light traveling within the waveguide may be guided toward a user's eyes through an output optical member (e.g., the output optical member (340) of FIG. 3). The screen display units (215a, 215b) may be determined based on the light emitted toward the user's eyes.

[0054] For example, light emitted from the display (205, 210) may be reflected in the grating region of the waveguide formed in the input optical member (220a, 220b) and the screen display portions (215a, 215b) and transmitted to the user's eyes.

[0055] The optical element may include at least one of a lens or an optical waveguide.

[0056] The lens can adjust the focus so that the screen output to the display can be viewed by the user. The lens may include, for example, at least one of a Fresnel lens, a pancake lens, or a multi-channel lens.

[0057] An optical waveguide can transmit image light generated from a display to a user's eyes. For example, the image light may represent light emitted by a light source (230a, 230b) that passes through a screen output area of ​​the display. The optical waveguide can be made of glass, plastic, or polymer. The optical waveguide can include a nano-pattern formed on a portion of an internal or external surface, for example, a grating structure having a polygonal or curved shape. An exemplary structure of the optical waveguide is described below in FIG. 3.

[0058] The vision sensor may include at least one of a camera sensor or a depth sensor.

[0059] The first camera (265a, 265b) is a recognition camera, and may be a camera used for 3DoF, 6DoF head tracking, hand detection, hand tracking, and spatial recognition. The first camera (265a, 265b) may mainly include a GS (global shutter) camera. Since a stereo camera is required for head tracking and spatial recognition, the first camera (265a, 265b) may include two or more GS cameras. The GS camera may have superior performance compared to the RS (rolling shutter) camera in terms of detecting and tracking fine movements such as rapid hand movements and fingers. For example, the GS camera may have low image blur. The first camera (265a, 265b) may capture image data used for spatial recognition for 6DoF and SLAM function through depth shooting. Additionally, a user gesture recognition function can be performed based on image data captured by the first camera (265a, 265b).

[0060] The second camera (270a, 270b) is an ET (eye tracking) camera that can be used to capture image data for detecting and tracking the user's pupils. The second camera (270a, 270b) is described later in FIG. 3.

[0061] The third camera (245) may be a camera for photography. The third camera (245) may include a high-resolution camera for capturing HR (high resolution) or PV (photo video) images. The third camera (245) may include a color camera equipped with functions for obtaining high-quality images, such as an AF function and optical image stabilization (OIS). The third camera (245) may be a GS camera or an RS camera.

[0062] The fourth camera unit (e.g., the face recognition camera (425, 426) of FIG. 4 below) is a face recognition camera, and the FT (face tracking) camera can be used to detect and track the user's facial expression.

[0063] A depth sensor (not shown) may be a sensor that senses information for determining the distance to an object, such as TOF (Time of Flight). TOF is a technology that measures the distance to an object using signals (such as near-infrared, ultrasound, or laser). A depth sensor based on TOF technology can measure the time of flight of a signal by transmitting a signal and measuring the signal at a receiver.

[0064] The light source (230a, 230b) (e.g., illumination module) may include a device (e.g., light emitting diode (LED)) that irradiates light of various wavelengths. The illumination module may be attached to various locations depending on the application. As an example, a first illumination module (e.g., LED device) attached around the frame of the augmented reality glasses device may emit light to assist in gaze detection when tracking eye movements with an ET camera. The first illumination module may include, for example, an IR LED of an infrared wavelength. As another example, a second illumination module (e.g., LED device) may be attached adjacent to a camera mounted around a hinge (240a, 240b) connecting the frame and the temple, or around a bridge connecting the frames. The second illumination module may emit light to supplement the ambient brightness when the camera is taking pictures. If it is difficult to detect a subject in a dark environment, the second illumination module may emit light.

[0065] A substrate (235a, 235b) (e.g., a printed circuit board (PCB)) can support the aforementioned components.

[0066] A printed circuit board (PCB) may be disposed on the temple portion of the glasses. The FPCB may transmit electrical signals to each module (e.g., a camera, a display, an audio module, a sensor module) and other printed circuit boards. In one embodiment, 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. In another example, the printed circuit board may be disposed on the central portion of the set. Electrical signals may be transmitted to each module and other printed circuit boards through the FPCB.

[0067] Other components may include, for example, at least one of a plurality of microphones (e.g., a first microphone (250a), a second microphone (250b), a third microphone (250c)), a plurality of speakers (e.g., a first speaker (255a), a second speaker (255b)), a battery (260), an antenna, or a sensor (e.g., an acceleration sensor, a gyro sensor, a touch sensor, etc.).

[0068] FIG. 3 illustrates examples of optical systems for an eye tracking camera, a transparent member, and a display according to various embodiments.

[0069] FIG. 3 is a diagram for explaining the operation of an eye-tracking camera included in an electronic device according to one embodiment. Referring to FIG. 3, a process is illustrated in which an eye-tracking camera (310) of an electronic device (301) according to one embodiment (e.g., the second camera (270a, 270b) of FIG. 2) tracks a user's eye (309), or in other words, the user's gaze, using light (e.g., infrared light) output from a display (320) (e.g., the first display (205) of FIG. 2, the second display (210) of FIG. 2).

[0070] The second camera (e.g., the second cameras (270a, 270b) of FIG. 2) may be an eye tracking camera (310) that collects information to position the center of a virtual image projected onto the electronic device (301) according to the direction in which the pupil of the wearer of the electronic device (301) is looking. The second camera may also include a GS camera to detect the pupil and track rapid eye movement. ET cameras may also be installed for the left and right eyes, respectively, and cameras with the same performance and specifications may be used. The eye tracking camera (310) may include a gaze tracking sensor (315). The gaze tracking sensor (315) may be included inside the eye tracking camera (310). Infrared light output from the display (320) may be transmitted to the user's eyes (309) as infrared reflected light (303) by a half mirror. The gaze tracking sensor (315) can detect infrared reflected light (303) and infrared transmitted light (305) reflected from the user's eye (309). The eye tracking camera (310) can track the user's eye (309), or in other words, the user's gaze, based on the detection result of the gaze tracking sensor (315).

[0071] The display (320) may include a plurality of visible light pixels and a plurality of infrared pixels. The visible light pixels may include R, G, and B pixels. The visible light pixels may output visible light corresponding to a virtual object image. The infrared pixels may output infrared light. The display (320) may include, for example, micro light emitting diodes (LEDs) or organic light emitting diodes (OLEDs).

[0072] The display optical pipe (350) and the eye tracking camera optical pipe (360) may be included inside a transparent member (370) (e.g., the first transparent member (225a) and the second transparent member (225b) of FIG. 2). The transparent member (370) may be formed of a glass plate, a plastic plate, or a polymer, and may be manufactured to be transparent or translucent. The transparent member (370) may be positioned to face the user's eyes. At this time, the distance between the transparent member (370) and the user's eyes (309) may be referred to as 'eye relief' (380).

[0073] The transparent member (370) may include optical waveguides (350, 360). The transparent member (370) may include an input optical member (330) and an output optical member (340). In addition, the transparent member (370) may include an eye-tracking splitter (375) that separates input light into multiple waveguides.

[0074] According to one embodiment, light incident on one end of the display light pipe (350) can be propagated inside the display light pipe (350) by the nano-pattern and provided to the user. In addition, the display light pipe (350) composed of a free-form prism can provide image light to the user through the reflected mirror by reflecting the incident light. The display light pipe (350) can 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 display light pipe (350) can guide display light (e.g., image light) emitted from a light source to the user's eyes by using at least one diffractive element or reflective element included in the display light pipe (350). For reference, also, in FIG. 3, the output optical member (340) is expressed as being separate from the eye-tracking optical waveguide (360), but the output optical member (340) may be included inside the eye-tracking optical waveguide (360).

[0075] According to various embodiments, the diffractive element may include an input optical member (330) and an output optical member (340). For example, the input optical member (330) may mean an input grating region. The output optical member (340) may mean an output grating region. The input grating region may serve as an input terminal that diffracts (or reflects) light output from a light source (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 region 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.

[0076] 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.

[0077] In one embodiment, light emitted from the display (320) may be guided along an optical path through an input optical element (330) into a waveguide. Light traveling within the waveguide may be guided toward the user's eyes through an output optical element (340). The screen display may be determined based on the light emitted toward the user's eyes.

[0078] FIGS. 4A and 4B are diagrams illustrating examples of the front and back of an electronic device according to various embodiments. FIG. 4A may be an external appearance of the electronic device (401) as viewed from a first direction (①), and FIG. 4B may be an external appearance of the electronic device (401) as viewed from a second direction (②).

[0079] Referring to FIG. 4A, according to various embodiments, an electronic device (401) (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, and the electronic device (301) of FIG. 3) may provide a service that provides an extended reality (XR) experience to a user. For example, an XR or XR service may be defined as a service that collectively refers to virtual reality (VR), augmented reality (AR), and / or mixed reality (MR).

[0080] According to one embodiment, the electronic device (401) may refer to a head-mounted device or a head-mounted display worn on the user's head, but may also be configured in the form of at least one of glasses, goggles, a helmet, or a hat. The electronic device (401) may include an OST (optical see-through) type configured to allow external light to reach the user's eyes through the glasses when worn, or a VST (video see-through) type configured to allow light emitted from the display to reach the user's eyes but block external light so that external light does not reach the user's eyes when worn.

[0081] According to one embodiment, the electronic device (401) may be worn on the user's head and may provide the user with an image related to an extended reality (XR) service. For example, the electronic device (401) may provide XR content (hereinafter referred to as an XR content image) that outputs at least one virtual object to be superimposed on a display area or an area determined to be the user's field of view (FoV). According to one embodiment, the XR content may refer to an image or image that appears to have at least one virtual object superimposed on an image related to a real space acquired through a camera (e.g., a camera for taking pictures) or a virtual space. According to one embodiment, the electronic device (401) may provide XR content based on a function being performed by the electronic device (401) and / or a function being performed by one or more external electronic devices (e.g., the electronic devices (102, 104) of FIG. 1, the server (108) of FIG. 1).

[0082] According to one embodiment, the electronic device (401) is at least partially controlled by an external electronic device (e.g., electronic devices (102 or 104) of FIG. 1), and may perform at least one function under the control of the external electronic device, but may also perform at least one function independently.

[0083] Referring to FIG. 4A, a vision sensor may be placed on a first surface of a housing of a main body (410) of an electronic device (401). The vision sensor may include cameras (e.g., cameras for second functions (411, 412), cameras for first functions (415)) and / or a depth sensor (417) for obtaining information related to the surrounding environment of the electronic device (401).

[0084] In one embodiment, the second function cameras (411, 412) can obtain images related to the surrounding environment of the electronic device (401). The first function cameras (415) can obtain images when the wearable electronic device is worn by the user. The first function cameras (415) can be used for hand detection and tracking, and recognition of user gestures (e.g., hand movements). The first function cameras (415) can be used for 3DoF, 6DoF head tracking, position (spatial, environmental) recognition, and / or movement recognition. In one embodiment, the second function cameras (411, 412) can also be used for hand detection and tracking, and user gestures.

[0085] In one embodiment, the depth sensor (417) 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 (417), cameras (411, 412, 415) may determine the distance to an object.

[0086] Referring to FIG. 4b, a camera (425, 426) for facial recognition and / or a display (421) (and / or lens) may be placed on the second surface (420) of the housing of the main body (410).

[0087] In one embodiment, a face recognition camera (425, 426) adjacent to the display may be used to recognize the user's face, or may recognize and / or track the user's two eyes.

[0088] In one embodiment, the display (421) (and / or lens) may be disposed on the second side (420) of the electronic device (401). In one embodiment, the electronic device (401) may not include some of the plurality of cameras (415). Although not shown in FIGS. 4A and 4B , the electronic device (401) may further include at least one of the configurations illustrated in FIG. 2 .

[0089] According to one embodiment, the electronic device (401) may include a main body (410) that mounts at least some of the components of FIG. 1, a display (421) (e.g., a display module (160) of FIG. 1) disposed in a first direction (①) of the main body (410), a first function camera (e.g., a recognition camera) (415) disposed in a second direction (②) of the main body (410), a second function camera (e.g., a shooting camera) (411, 412) disposed in a second direction (②), a third function camera (e.g., a gaze tracking camera) (428) disposed in the first direction (①), a fourth function camera (e.g., a face recognition camera) (425, 426) disposed in the first direction (①), a depth sensor (417) disposed in the second direction (②), and a touch sensor (413) disposed in the second direction (②). Although not shown in the drawing, the main body (410) includes a memory (e.g., memory (130) of FIG. 1) and a processor (e.g., processor (120) of FIG. 1), and may further include other components shown in FIG. 1.

[0090] According to one embodiment, the display (421) may include a liquid crystal display (LCD), a digital mirror device (DMD), a liquid crystal on silicon (LCoS), an organic light emitting diode (OLED), or a micro light emitting diode (micro LED).

[0091] In one embodiment, when the display (421) is formed of one of a liquid crystal display (LCD), a digital mirror display (DMD), or a silicon liquid crystal display (SiLCD), the electronic device (401) may include a light source that irradiates light to a screen output area of ​​the display (421). In another embodiment, when the display (421) can generate light on its own, for example, when the electronic device (401) is formed of one of an organic light emitting diode (OLED) or a micro LED, the electronic device (401) may provide a good quality XR content image to the user even without including a separate light source. In one embodiment, when the display (421) is formed of an organic light emitting diode (OLED) or a micro LED, a light source is unnecessary, and thus the electronic device (401) may be lightweight.

[0092] According to one embodiment, the display (421) may include a first transparent member (421a) and / or a second transparent member (421b). The user may use the electronic device (401) while wearing it on his or her face. The first transparent member (421a) and / or the second transparent member (421b) may be formed of a glass plate, a plastic plate, or a polymer, and may be manufactured to be transparent or translucent. According to one embodiment, the first transparent member (421a) may be arranged to face the user's left eye in the third direction (③), and the second transparent member (421b) may be arranged to face the user's right eye in the fourth direction (④). According to various embodiments, when the display (421) is transparent, it may be arranged at a position facing the user's eyes to form a display area.

[0093] According to one embodiment, the display (421) may include a lens including a transparent waveguide. The lens may serve to adjust the focus so that the screen (e.g., XR content image) output to the display (421) can be viewed by the user's eyes. For example, light emitted from the display panel may pass through the lens and be transmitted to the user through a waveguide formed within the lens. The lens may be configured as a Fresnel lens, a pancake lens, or a multi-channel lens.

[0094] An optical waveguide (e.g., a waveguide) may serve to transmit light generated by the display (421) to the user's eyes. The optical waveguide may be made of glass, plastic, or a 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 optical waveguide, that is, an output image of the display (421), may be propagated within the optical waveguide and provided to the user. In addition, an optical waveguide composed of a free-form prism may provide the incident light to the 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 an image output from the display (421) to the user's eyes by using at least one diffractive element or reflective element included in the optical waveguide.

[0095] According to one embodiment, 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 region, and the output optical member (not shown) may mean an output grating region. The input grating region may serve as an input terminal that diffracts (or reflects) light output from a light source (e.g., a Micro LED) to transmit the light to a transparent member (e.g., a first transparent member (421a), a second transparent member (421b)) of the display area. The output grating region 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 the optical waveguide to a user's eye.

[0096] In some embodiments, the reflective element may comprise a total internal reflection (TIR) ​​optical element or waveguide for total internal reflection. For example, total internal reflection may refer to a method of directing light such that light (e.g., a virtual image) entering through an input grating region is reflected substantially 100% from one surface (e.g., a specific surface) of the optical waveguide, thereby transmitting substantially 100% of the light to the output grating region at an angle of incidence.

[0097] In one embodiment, light emitted from the display (421) may be guided along an optical path through an input optical element into a waveguide. Light traveling within the optical waveguide may be guided toward the user's eyes through an output optical element. The display area may be determined based on the light emitted toward the user's eyes.

[0098] According to one embodiment, the electronic device (401) may include a plurality of cameras. For example, the cameras may include a first function camera (e.g., a recognition camera) (415) disposed in the second direction (②) of the main body (410), a second function camera (e.g., a shooting camera) (411, 412) disposed in the second direction (②), a third function camera (e.g., a gaze tracking camera) (428) disposed in the first direction (①), and / or a fourth function camera (e.g., a face recognition camera) (425, 426) disposed in the first direction (①), but may further include cameras for other functions not shown.

[0099] The first function camera (e.g., recognition camera) (415) can be used for the purpose of detecting user movement or recognizing user gestures. The first function camera (415) can support at least one of head tracking, hand detection and hand tracking, and spatial recognition. For example, the first function camera (415) mainly uses a GS (global shutter) camera, which has superior performance compared to an RS (rolling shutter) camera, to detect and track fine movements of hand movements and fingers, and can be configured as a stereo camera including two or more GS cameras for head tracking and spatial recognition. The first function camera (415) can perform a SLAM (simultaneous localization and mapping) function to recognize information (e.g., location and / or direction) related to the surrounding space through spatial recognition for 6DoF and depth shooting.

[0100] A second function camera (e.g., a camera for shooting) (411, 412) can be used to capture the outside and generate an image or video corresponding to the outside and transmit it to a processor (e.g., a processor (120) of FIG. 1). The processor can display the image provided from the second function camera (411, 412) on a display (421). The second function camera (411, 412) may be referred to as HR (high resolution) or PV (photo video) and may include a high-resolution camera. For example, the second function camera (411, 412) may include a color camera equipped with functions for obtaining high-quality images, such as an AF (auto focus) function and an OIS (optical image stabilizer), but is not limited thereto, and the second function camera (411, 412) may also include a GS camera or an RS camera.

[0101] A third function camera (e.g., a gaze tracking camera) (428) may be positioned on the display (421) (or inside the main body) so that the camera lens faces the user's eyes when the user wears the electronic device (401). The third function camera (428) may be used for the purpose of detecting and tracking (ET: eye tracking) the pupil. The processor may track the movements of the user's left and right eyes in the images received from the third function camera (428) to determine the gaze direction. By tracking the position of the pupil in the images, the processor may ensure that the center of the XR content image displayed in the display area is positioned according to the direction in which the pupil is looking. As an example, a GS camera may be used as the third function camera (428) to detect the pupil and track the movement of the pupil. The third function cameras (428) may be installed respectively for the left and right eyes, and each camera having the same performance and specifications may be used.

[0102] A fourth functional camera (e.g., a camera for facial recognition) (425, 426) can be used to detect and track (FT: face tracking) the user's facial expression when the user wears the electronic device (401).

[0103] According to one embodiment, the electronic device (401) may include a lighting unit (e.g., LED) (not shown) as an auxiliary means for the cameras. For example, the third function camera (428) may use lighting included in the display to direct the emitted light (e.g., IR LED of infrared wavelength) toward the user's eyes as an auxiliary means to facilitate gaze detection when tracking eye movements. As another example, the second function cameras (411, 412) may further include a lighting unit (e.g., flash) as an auxiliary means to supplement the surrounding brightness when taking external pictures.

[0104] According to one embodiment, a depth sensor (or depth camera) (417) may be used to determine the distance to an object (e.g., an object), such as time of flight (TOF). Time of flight (TOF) is a technology that measures the distance to an object using a signal (e.g., near-infrared, ultrasound, or laser). After a signal is transmitted from a transmitter, a receiver measures the signal, and the distance to the object can be measured based on the flight time of the signal.

[0105] According to one embodiment, the touch sensor (413) may be arranged in the second direction (②) of the main body (410). For example, when a user wears the electronic device (401), the user's eyes may look in the first direction (①) of the main body. The touch sensor (413) may be implemented as a single type or a left / right separated type depending on the shape of the main body (410), but is not limited thereto. For example, when the touch sensor (413) is implemented as a left / right separated type as illustrated in FIG. 4A, when a user wears the electronic device (401), the first touch sensor (413a) may be arranged at the user's right eye position, such as in the third direction (③), and the second touch sensor (413b) may be arranged at the user's left eye position, such as in the fourth direction (④).

[0106] The touch sensor (413) can recognize a touch input using at least one of, for example, a capacitive, pressure-sensitive, infrared, or ultrasonic method. For example, the capacitive touch sensor (413) can recognize a physical touch (or contact) input or a hovering input (or proximity) of an external object. According to some embodiments, the electronic device (401) may utilize a proximity sensor (not shown) to recognize proximity of an external object.

[0107] According to one embodiment, the touch sensor (413) has a two-dimensional surface and can transmit touch data (e.g., touch coordinates) of an external object (e.g., a user's finger) that comes into contact with the touch sensor (413) to the processor (120). The touch sensor (413) can detect a hovering input for an external object (e.g., a user's finger) that approaches within a first distance from the touch sensor (413), or detect a touch input that touches the touch sensor (413).

[0108] According to one embodiment, the touch sensor (413) may provide two-dimensional information about the point of contact as “touch data” to the processor (120) when an external object touches the touch sensor (413). The touch data may be described as a “touch mode.” The touch sensor (413) may provide hovering data about the time or location of hovering around the touch sensor (413) to the processor (120) when an external object is located within a first distance from the touch sensor (or in proximity, hovering above the touch sensor). The hovering data may be described as a “hovering mode / proximity mode.”

[0109] According to one embodiment, the electronic device (401) may obtain hovering data using at least one of a touch sensor (413), a proximity sensor (not shown), or / and a depth sensor (417) to generate information about a distance, location, or time point between the touch sensor (413) and an external object.

[0110] According to one embodiment, the interior of the main body (410) may include a processor (e.g., processor (120) of FIG. 1) and memory (e.g., memory (130) of FIG. 1).

[0111] Memory can store various instructions that can be executed by the processor. Instructions can include arithmetic and logical operations, data transfer, or control commands such as input / output that can be recognized by the processor. Memory can temporarily or permanently store various data, including volatile memory (e.g., volatile memory (132) of FIG. 1) and non-volatile memory (e.g., non-volatile memory (134) of FIG. 1).

[0112] The processor may be a configuration that is operatively, functionally, and / or electrically connected directly or indirectly to each component of the electronic device (401) and that can perform calculations or data processing related to control and / or communication of each component. The operations performed by the processor may be stored in memory and, when executed, executed by instructions that cause the processor to operate.

[0113] Hereinafter, the computational and data processing functions that the processor can implement on the electronic device (401) are not limited, but a series of operations related to the XR content service function will be described. The operations of the processor described below can be performed by executing instructions stored in memory.

[0114] According to one embodiment, the processor may generate a virtual object based on virtual information based on image information. The processor may output a virtual object related to an XR service together with background space information through the display (421). For example, the processor may capture an image related to a real space corresponding to the field of view of a user wearing the electronic device (401) through a second function camera (411, 412) to obtain image information or generate a virtual space for a virtual environment. For example, the processor may control the display (421) to display XR content (hereinafter referred to as an XR content screen) in which at least one virtual object is output so as to be overlapped in an area determined to be a field of view or a field of view (FoV) of the user.

[0115] According to one embodiment, the electronic device (401) may have a form factor for being worn on a user's head. The electronic device (401) may further include a strap and / or a wearable member for being secured on a body part of the user. The electronic device (401) may provide a user experience based on augmented reality, virtual reality, and / or mixed reality while being worn on the user's head.

[0116] FIG. 5 illustrates examples of construction of a virtual space, input from a user within the virtual space, and output to the user according to various embodiments.

[0117] An electronic device (501) (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, the electronic device (301) of FIG. 3, and the electronic device (401) of FIG. 4) can obtain spatial information about a physical space in which the sensor is located using a sensor. The spatial information can include a geographical location of the physical space in which the sensor is located, a size of the space, an appearance of the space, a location of a physical object (551) arranged in the space, a size of the physical object (551), an appearance of the physical object (551), and illuminant information. The appearance of the space and the physical object (551) can include at least one of a shape, a texture, or a color of the space and the physical object (551). The illuminant information is information about a light source that emits light acting within the physical space, and can include at least one of an intensity, a direction, or a color of the illumination. The aforementioned sensor can collect information for providing augmented reality. For example, referring to the augmented reality device illustrated in FIGS. 2 to 4, the sensor may include a camera and a depth sensor. However, the present invention is not limited thereto, and the sensor may further include at least one of an infrared sensor, a depth sensor (e.g., a lidar sensor, a radar sensor, or a stereo camera), a gyro sensor, an acceleration sensor, or a geomagnetic sensor.

[0118] The electronic device (501) can collect spatial information over multiple time frames. For example, in each time frame, the electronic device (501) can collect spatial information about a portion of a scene within a sensing range (e.g., field of view (FOV)) of a sensor at the location of the electronic device (501) in physical space. By analyzing the spatial information of multiple time frames, the electronic device (501) can track changes in an object (e.g., movement of position or change of state) over time. The electronic device (501) can also obtain integrated spatial information (e.g., an image that spatially stitches scenes around the electronic device (501) in physical space) for the integrated sensing range of the multiple sensors by comprehensively analyzing the spatial information collected through the multiple sensors.

[0119] An electronic device (501) according to one embodiment can analyze a physical space into three-dimensional information by utilizing various input signals of sensors (e.g., sensing data from an RGB camera, an infrared sensor, a depth sensor, or a stereo camera). For example, the electronic device (501) can analyze at least one of the shape, size, and position of a physical space, and the shape, size, or position of a physical object (551).

[0120] For example, the electronic device (501) can detect an object captured within a scene corresponding to the camera's field of view using the camera's sensing data (e.g., a captured image). The electronic device (501) can determine a label of a physical object (551) from the camera's two-dimensional scene image (e.g., information indicating the classification of the object, including a value indicating a chair, a monitor, or a plant) and an area (e.g., a bounding box) occupied by the physical object (551) within the two-dimensional scene. Accordingly, the electronic device (501) can obtain two-dimensional scene information at a position viewed by the user (590). In addition, the electronic device (501) can also calculate the physical space location of the electronic device (501) based on the camera's sensing data.

[0121] The electronic device (501) can obtain location information of the user (590) and depth information of the actual space in the viewing direction using sensing data (e.g., depth data) of the depth sensor. The depth information is information indicating the distance from the depth sensor to each point and can be expressed in the form of a depth map. The electronic device (501) can analyze the distance of each pixel in the three-dimensional position viewed by the user (590).

[0122] The electronic device (501) can acquire information including a 3D point cloud and mesh using various sensing data. The electronic device (501) can analyze a physical space to acquire a surface, mesh, or 3D coordinate point cluster that constitutes the space. Based on the information acquired as described above, the electronic device (501) can acquire a 3D point cloud representing physical objects.

[0123] The electronic device (501) can analyze a physical space to obtain information including at least one of a three-dimensional position coordinate, a three-dimensional shape, or a three-dimensional size (e.g., a three-dimensional bounding box) of physical objects placed in the physical space.

[0124] Accordingly, the electronic device (501) can obtain information on a physical object detected in a three-dimensional space and semantic segmentation information on the three-dimensional space. The physical object information may include at least one of the position, appearance (e.g., shape, texture, and color), or size of the physical object (551) in the three-dimensional space. The semantic segmentation information is information that semantically divides the three-dimensional space into subspaces, and may include, for example, information indicating that the three-dimensional space is divided into an object and a background, and information indicating that the background is divided into a wall, a floor, and a ceiling. The electronic device (501) can obtain and store three-dimensional information (e.g., spatial information) on the physical object (551) and the physical space as described above. The electronic device (501) can store three-dimensional position information of the user (590) in the space together with the spatial information.

[0125] An electronic device (501) according to one embodiment can construct a virtual space (500) based on the physical location of the electronic device (501) and / or the user (590). The electronic device (501) can create the virtual space (500) by referring to the spatial information described above. The electronic device (501) can create a virtual space (500) of the same scale as the physical space based on the spatial information and place objects within the created virtual space (500). The electronic device (501) can provide a complete virtual reality to the user (590) by outputting an image that represents the entire physical space. The electronic device (501) can provide mixed reality (MR) or augmented reality (AR) by outputting an image that represents a part of the physical space. However, although the construction of a virtual space (500) based on spatial information acquired through analysis of the aforementioned physical space is described, the electronic device (501) may also construct a virtual space (500) regardless of the physical location of the user (590). In this specification, the virtual space (500) is a space corresponding to augmented reality or virtual reality, and may also be referred to as a metaverse space.

[0126] For example, the electronic device (501) may provide a virtual graphic representation that replaces at least a portion of a physical space. An electronic device (501) based on optical see-through may output a virtual graphic representation by overlaying the virtual graphic representation on a screen area corresponding to at least a portion of the space on a screen display unit. An electronic device (501) based on video see-through may output an image generated by replacing an image area corresponding to at least a portion of a space image corresponding to a physical space rendered based on spatial information with a virtual graphic representation. The electronic device (501) may replace at least a portion of a background in a physical space with a virtual graphic representation, but is not limited thereto. The electronic device (501) may also perform only additional placement of a virtual object (552) within a virtual space (500) based on spatial information without changing the background.

[0127] The electronic device (501) can place and output a virtual object (552) in a virtual space (500). The electronic device (501) can set an operation area of ​​the virtual object (552) in a space occupied by the virtual object (552) (e.g., a volume corresponding to the appearance of the virtual object (552). The operation area may indicate an area where manipulation of the virtual object (552) occurs. In addition, the electronic device (501) can output a physical object (551) by replacing it with the virtual object (552). The virtual object (552) corresponding to the physical object (551) may have a shape identical to or similar to that of the physical object (551). However, the present invention is not limited thereto, and the electronic device (501) may also set only an operation area in a space occupied by the physical object (551) or in a location corresponding to the physical object (551) without outputting a virtual object (552) that replaces the physical object (551). In other words, the electronic device (501) can transmit visual information representing a physical object (551) (e.g., light reflected from the physical object (551) or an image captured of the physical object (551)) to the user (590) without change, and set a manipulation area on the physical object (551). The manipulation area can be set to the same shape and volume as the space occupied by the virtual object (552) or the physical object (551), but is not limited thereto. The electronic device (501) can also set a manipulation area smaller than the space occupied by the virtual object (552) or the space occupied by the physical object (551).

[0128] According to one embodiment, the electronic device (501) may place a virtual object (not shown) representing the user (590) (e.g., an avatar object) within the virtual space (500). When the avatar object is provided in a first-person view, the electronic device (501) may visualize a graphical representation corresponding to a part (e.g., a hand, a torso, or a leg) of the avatar object to the user (590) through the aforementioned display (e.g., an optical see-through display or a video see-through display). However, the present invention is not limited thereto, and when the avatar object is provided in a third-person view, the electronic device (501) may also visualize a graphical representation corresponding to the entire shape (e.g., a back view) of the avatar object to the user (590) through the aforementioned display. The electronic device (501) may provide the user (590) with an experience integrated with the avatar object.

[0129] In addition, the electronic device (501) can provide an avatar object of another user who has entered the same virtual space (500). The electronic device (501) can receive feedback information that is the same or similar to feedback information (e.g., information based on at least one of visual, auditory, or tactile senses) provided to another electronic device (not shown) who has entered the same virtual space (500). For example, when an object is placed in a certain virtual space (500) and multiple users access the virtual space (500), the electronic devices (501) of the multiple users can receive feedback information (e.g., graphical representation, sound signal, or haptic feedback) of the same object placed in the virtual space (500) and provide the feedback information to each user (590).

[0130] The electronic device (501) can detect input to an avatar object of another electronic device and can also receive feedback information from the avatar object of the other electronic device. The exchange of input and feedback for each virtual space (500) can be performed by a server (e.g., server (108) of FIG. 1). For example, a server (e.g., a server providing a metaverse space) can transmit input and feedback between an avatar object of a user (590) and an avatar object of another user between users (590). However, the present invention is not limited thereto, and the electronic device (501) can establish direct communication with another electronic device without going through a server to provide input or receive feedback based on an avatar object.

[0131] For example, the electronic device (501) may determine that a physical object (551) corresponding to the selected manipulation area has been selected by the user (590) based on detecting a user input for selecting an manipulation area. The user's (590) input may include at least one of a gesture input using a part of the body (e.g., a hand or an eye), an input using a separate virtual reality accessory device, or a user's voice input.

[0132] A gesture input is an input corresponding to a gesture identified based on tracking a body part (510) of a user (590), and for example, the gesture input may include an input for pointing or selecting an object. The gesture input may include at least one of a gesture in which a body part (e.g., a hand) faces an object for a predetermined period of time or longer, a gesture in which a body part (e.g., a finger, an eye, a head) points to an object, or a gesture in which a body part and an object make spatial contact. A gesture in which an eye points to an object may be identified based on eye tracking. A gesture in which the head points to an object may be identified based on head tracking.

[0133] Tracking of a body part (510) of a user (590) may be performed primarily based on a camera of the electronic device (501), but is not limited thereto. The electronic device (501) may also track the body part (510) based on the cooperation of sensing data of a vision sensor (e.g., image data of a camera and depth data of a depth sensor) and information collected by an accessory device described below (e.g., controller tracking, finger tracking within the controller). Finger tracking may be performed by sensing the distance or contact between an individual finger and the controller based on a sensor built into the controller (e.g., an infrared sensor).

[0134] The virtual reality accessory device may include a ride-on device, a wearable device, a controller device (520), or other sensor-based device. The ride-on device is a device that a user (590) rides on and operates, and may include, for example, at least one of a treadmill-type device or a chair-type device. The wearable device is a manipulation device that is worn on at least a part of the user's (590) body, and may include, for example, at least one of a full-body and half-body suit-type controller, a vest-type controller, a shoe-type controller, a bag-type controller, a glove-type controller (e.g., a haptic glove), or a face mask-type controller. The controller device (520) may include, for example, an input device (e.g., a stick-type controller or a gun) that is operated by a hand, foot, toe, or other body part (510).

[0135] The electronic device (501) may establish direct communication with the accessory device to track at least one of the location or motion of the accessory device, but is not limited thereto. The electronic device (501) may also communicate with the accessory device via a base station for virtual reality.

[0136] For example, the electronic device (501) may determine that the virtual object (552) has been selected based on detecting an action of gazing at the virtual object (552) for a predetermined period of time or longer through the aforementioned eye gaze tracking technology. As another example, the electronic device (501) may recognize a gesture indicating the virtual object (552) through hand tracking technology. The electronic device (501) may determine that the virtual object (552) has been selected based on whether the direction pointed by the tracked hand indicates the virtual object (552) for a predetermined period of time or longer, or whether the hand of the user (590) contacts or enters an area occupied by the virtual object (552) within the virtual space (500).

[0137] The user's voice input is an input corresponding to the user's voice acquired by the electronic device (501), and may include, for example, voice data sensed by an input module (e.g., a microphone) of the electronic device (501) or received from an external electronic device of the electronic device (501). The electronic device (501) may determine that a physical object (551) or a virtual object (552) has been selected by analyzing the user's voice input. For example, the electronic device (501) may determine that at least one of the physical object (551) or the virtual object (552) corresponding to the detected keyword has been selected based on detecting a keyword indicating at least one of the physical object (551) or the virtual object (552) from the user's voice input.

[0138] The electronic device (501) may provide feedback as described below in response to the user (590) input described above.

[0139] Feedback may include visual feedback, auditory feedback, tactile feedback, olfactory feedback, or gustatory feedback. The feedback may be rendered by a server (108), an electronic device (101), or an external electronic device (102), as described above in FIG. 1.

[0140] Visual feedback may include outputting an image through a display (e.g., a transparent display or an opaque display) of the electronic device (501).

[0141] Auditory feedback may include outputting sound through a speaker of the electronic device (501).

[0142] Tactile feedback may include force feedback that simulates weight, shape, texture, dimension, and dynamics. For example, a haptic glove may include haptic elements (e.g., electrical muscles) that can simulate the sensation of touch by tensing and relaxing the body of a user (590). The haptic elements within the haptic glove may act as tendons. The haptic glove may provide haptic feedback to the entire hand of the user (590). The electronic device (501) may provide feedback indicating the shape, size, and stiffness of an object through the haptic glove. For example, the haptic glove may generate forces that mimic the shape, size, and stiffness of an object. The exoskeleton of the haptic glove (or suit-like device) may include sensors and finger motion measurement devices, and may transmit tactile information to the body by transmitting a force (e.g., an electromagnetic, DC motor, or pneumatic-based force) that pulls a cable to the fingers of the user (590). Hardware providing tactile feedback may include sensors, actuators, power sources, and wireless transmission circuitry. Haptic gloves may operate by inflating and deflating inflatable air bladders on the glove surface.

[0143] The electronic device (501) may provide feedback to the user (590) based on the selection of an object within the virtual space (500). For example, the electronic device (501) may output a graphical representation indicating the selected object (e.g., an expression highlighting the selected object) through the display. As another example, the electronic device (501) may output a sound (e.g., a voice) guiding the selected object through the speaker. As another example, the electronic device (501) may provide the user (590) with a haptic movement that simulates the tactile sensation of the corresponding object by transmitting an electrical signal to a haptic-enabled accessory device (e.g., a haptic glove).

[0144] FIG. 6 is a flowchart schematically illustrating a process of placing a virtual object corresponding to a real object in a virtual space according to various embodiments.

[0145] An electronic device according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (401) of FIG. 4, electronic device (501) of FIG. 5) may be worn by a user. The electronic device may be an extended reality device (XR device). The XR device may include all of a virtual reality (VR) device, an augmented reality (AR) device, and a mixed reality (MR) device.

[0146] An electronic device can construct a virtual space (e.g., a virtual space (500) of FIG. 5) based on the physical location of the electronic device and / or the user, and can place virtual objects within the virtual space. As described in FIG. 5, the virtual space may be a space corresponding to augmented reality or virtual reality. The electronic device can create a three-dimensional virtual object by performing three-dimensional modeling on a real object located in the real space. Below, a process of the electronic device modeling a real object and placing the created virtual object in the virtual space is briefly described.

[0147] In operation (610), the electronic device can obtain a real space image using a camera and identify an external object from the obtained real space image.

[0148] In one embodiment, an electronic device may be worn on a user's head and provide the user with images related to extended reality (XR). The user may enter a virtual space by wearing the electronic device. When the electronic device receives a signal requesting entry into the virtual space from the user, the electronic device may turn on a camera (e.g., the first camera (265a, 265b) of FIG. 2 or the functional camera (415) of FIG. 4A) that captures the real space to construct the virtual space. The camera may be used to recognize the real space. The camera may capture the real space with its field of view. For example, the electronic device may measure the viewing direction and viewing angle of the user wearing the electronic device and rotate the camera based on the measured viewing direction and viewing angle of the user. In other words, the electronic device may obtain a real space image captured from the camera according to the user's viewing direction and viewing angle.

[0149] In one embodiment, the electronic device can identify an external object from an acquired real-space image. The electronic device can identify an external object from the acquired real-space image through image analysis.

[0150] In operation (620), the electronic device can determine an object of interest among the identified external objects based on a focus mode of the electronic device.

[0151] In one embodiment, the electronic device may determine an object of interest based on settings for the virtual space. For example, the settings for the virtual space may include a focus mode of the electronic device.

[0152] In one embodiment, the electronic device can set a focus mode. For example, the electronic device can set the focus mode based on a user input. The electronic device can determine the type of object to focus on based on the focus mode. More specifically, the electronic device can determine an external object identified from a real-space image and having an object type corresponding to the focus mode as the object of interest.

[0153] In operation (630), the electronic device can place a virtual object corresponding to the determined object of interest in a virtual space.

[0154] In one embodiment, an electronic device may generate a virtual object corresponding to an object of interest by modeling the object of interest. The electronic device may place the generated virtual object in a virtual space. When placing multiple virtual objects in a virtual space, the electronic device may place the virtual objects in the virtual space so that they do not overlap each other. The electronic device may place the virtual object corresponding to the object of interest close to the location in the virtual space that corresponds to the location of the object of interest in the real space.

[0155] FIG. 7 is a diagram illustrating a process of identifying an external object from a real space image according to various embodiments.

[0156] In one embodiment, the electronic device (710) can identify external objects (e.g., a stand (731), a memo (732), a computer (733)) from a real-space image (720) acquired from a camera (e.g., a first camera (265a, 265b) of FIG. 2 or a functional camera (415) of FIG. 4a).

[0157] In one embodiment, the electronic device (710) can identify external objects (e.g., a stand (731), a notepad (732), a computer (733)) from a real-space image (720) through image analysis. The electronic device (710) can identify external objects from the real-space image (720) using a machine learning model. For example, the electronic device (710) can identify external objects by inputting the real-space image (720) into a convolutional neural network (CNN) model, which is a machine learning model.

[0158] In one embodiment, the electronic device (710) can set a reality level. The reality level can indicate the degree to which the virtual space resembles the real space. A higher reality level increases the degree to which the virtual space resembles the real space, while a lower reality level decreases the degree to which the virtual space resembles the real space. For example, the electronic device (710) can change the reality level based on input from the user (711).

[0159] In one embodiment, the electronic device (710) may determine the size of an identifiable external object in a real space image (720) based on a reality level. The electronic device (710) may decrease the minimum size or small size of an identifiable external object in a real space image (720) as the reality level increases. On the other hand, the electronic device (710) may increase the minimum size or small size of an identifiable external object in a real space image (720) as the reality level decreases. In other words, the electronic device (710) may maintain or increase the number of identifiable external objects in a real space image (720) as the reality level increases. On the other hand, the electronic device (710) may maintain or decrease the number of identifiable external objects in a real space image (720) as the reality level decreases.

[0160] For example, the electronic device (710) can adjust the size of an identifiable external object in a real space image (720) using a bounding box. The electronic device (710) can extract a bounding box (e.g., a bounding box (741)) surrounding a candidate object (e.g., a stand (731)) from the real space image (720). The bounding box may have a rectangular shape, but the shape of the bounding box is not necessarily limited thereto. The electronic device (710) can identify a candidate object located within a bounding box larger than a threshold size among the bounding boxes (e.g., a bounding box (741)) extracted from the real space image (720) as an external object, and can not identify a candidate object located within a bounding box smaller than the threshold size as an external object. The electronic device (710) can reduce the minimum size or small size of an identifiable external object in a real space image (720) by reducing the threshold size of a bounding box for identifying an external object as the reality level increases.

[0161] As another example, the electronic device (710) can adjust the size of an identifiable external object in a real space image (720) using a machine learning model. The machine learning model is a model designed to extract an external object from an image based on a reality level and an input image, and may include, for example, a neural network. The machine learning model may be trained so that as the reality level increases, the minimum size or small size of an identifiable external object in the image decreases. The electronic device (710) can obtain external objects (e.g., a stand (731), a memo pad (732), a computer (733)) as output data of the machine learning model by inputting the real space image (720) and the reality level into the machine learning model.

[0162] In another embodiment, the electronic device (710) can change the display method of the screen according to the reality level. By changing the display method of the screen according to the reality level, the electronic device (710) can change the degree to which the virtual space is constructed similar to the real space. For example, the reality levels may include a first level, a second level, and a third level, and the reality levels may increase in the order of the first level, the second level, and the third level. For example, when the reality level is set to the first level, the electronic device (710) can display a VR screen on the display. For example, when the reality level is set to the second or third level, the electronic device (710) can display an AR screen on the display. In this case, when the reality level is set to the second level, the electronic device (710) can blur the real space image acquired from the camera and display it on the screen. On the other hand, when the electronic device (710) sets the reality level to the third level, it can display the actual spatial image acquired from the camera on the screen without blurring. An example of changing the screen display method is described in more detail in FIG. 13.

[0163] FIG. 8 is a diagram illustrating a process for determining an object of interest among identified external objects according to various embodiments.

[0164] In one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (401) of FIG. 4, electronic device (501) of FIG. 5, electronic device (710) of FIG. 7) may determine one or more objects of interest (e.g., computer (841), memo (842), memo (843)) among identified external objects (e.g., stand (731), memo (732), computer (733) of FIG. 7) based on a focus mode of the electronic device.

[0165] In one embodiment, the electronic device may determine, among the identified external objects (e.g., the stand (731), the memo (732), and the computer (733) of FIG. 7), an external object having an object type corresponding to the focus mode of the electronic device as an object of interest. In one embodiment, the electronic device may not determine, among the identified external objects (e.g., the stand (731), the memo (732), and the computer (733) of FIG. 7), an external object having an object type other than the object type corresponding to the focus mode of the electronic device as an object of interest.

[0166] In one embodiment, when the focus mode is work mode, the electronic device may determine the object type corresponding to the work mode as a work-related object type. Work-related object types may include, for example, a computer, a tablet, a book, a notepad, printed matter, a desk, a calendar, and a notebook. When the focus mode is living room mode, the electronic device may determine the object type corresponding to the living room mode as a living room-related object type. Living room-related object types may include, for example, a TV, a sofa, a chair, a desk, and a bowl. When the focus mode is kitchen mode, the electronic device may determine the object type corresponding to the kitchen mode as a kitchen-related object type. Kitchen-related object types may include, for example, a refrigerator, an induction range, a dishwasher, a cutting board, and kitchen utensils. When the focus mode is game mode, the electronic device may determine the object type corresponding to the game mode as a game-related object type. Game-related object types may include, for example, a TV, a game controller, and the like. When the focus mode is pet mode, the electronic device can determine the object type corresponding to the pet mode as an object type related to pets. Examples of pet-related object types include dogs, cats, and food bowls.

[0167] In one embodiment, an electronic device can simultaneously enter two or more focus modes. For example, the electronic device can simultaneously enter both work mode and pet mode. In this case, the electronic device can set both external objects identified in the real-space image (820) with an object type corresponding to the work mode and an external object with an object type corresponding to the pet mode as objects of interest.

[0168] In one embodiment, the electronic device can determine objects of interest among external objects identified from a real-space image (820) based on the focus mode of the electronic device and user input. In other words, the electronic device can add or exclude objects of interest based on the user input. For example, the electronic device can exclude some external objects having an object type corresponding to the focus mode of the electronic device from the objects of interest based on the user input. The electronic device can add some external objects having an object type other than the object type corresponding to the focus mode of the electronic device as objects of interest based on the user input. For example, the electronic device can track the movement of the user's eyes using an eye tracking camera (e.g., the eye tracking camera (310) of FIG. 3) and detect the user's gaze. For example, the electronic device can identify an object corresponding to the user's gaze, and if the user's gaze remains on the object for a preset period of time, the electronic device can display an interface object on the screen that asks whether to add or exclude the object as an object of interest. The electronic device can add or exclude the object as an object of interest based on the user's input regarding the interface object displayed on the screen.

[0169] FIG. 9 is a diagram illustrating a process of creating a virtual object corresponding to an object of interest and placing the virtual object in a virtual space according to various embodiments.

[0170] In one embodiment, an electronic device can generate a virtual object corresponding to an object of interest. The virtual object can be, for example, a two-dimensional or three-dimensional shape. FIG. 9 primarily describes a case where the electronic device generates a three-dimensional virtual object. For example, the electronic device can load 3D data stored for the same object type as the object of interest from a database of the electronic device. The electronic device can also establish communication with another electronic device and load 3D data stored for the same object type as the object of interest from the database of the other electronic device.

[0171] In one embodiment, the electronic device can generate a virtual object corresponding to an object of interest based on loaded 3D data. The database can store visual information (e.g., information regarding shape, size, surface, texture, etc.) for each object type and information for performing a rendering operation on the virtual object in a virtual space (900). The database can store information for generating each object of the same object type, having various shapes and sizes, as a virtual object.

[0172] For example, the electronic device may determine a computer (941), which is an external object identified from a real space image (920), as an object of interest. In this case, the electronic device may load 3D data stored for the same object type as the computer (941) from a database. More specifically, the electronic device may analyze the shape and size of the computer (941) identified from the real space image (920), and load 3D data for creating a virtual object of an object having the same object type as the computer (941) and a similar shape and size from the database. The electronic device may use the loaded 3D data to create a three-dimensional virtual object (951) corresponding to the computer (941).

[0173] In one embodiment, the electronic device may provide a visual effect to a virtual object corresponding to an object of interest. For example, if the electronic device establishes communication with the object of interest or recognizes a character on the surface of the object of interest, the electronic device may provide a visual effect to the virtual object corresponding to the object of interest.

[0174] Each embodiment may be used in combination with any other embodiment(s) described herein.

[0175] In one embodiment, when an electronic device can establish communication with an object of interest (e.g., a computer (941)), the electronic device can provide a visual effect to a virtual object (e.g., a virtual object (951)) corresponding to the object of interest (e.g., a computer (941)) by establishing communication with the object of interest (e.g., a computer (941)). The electronic device can link screen information displayed on a display of the object of interest (e.g., a computer (941)) with which communication has been established and output the screen information to the virtual object (e.g., a virtual object (951)) corresponding to the object of interest (e.g., a computer (941)). For example, the electronic device can receive information about a screen output on the display of the object of interest (e.g., a computer (941)) from the object of interest (e.g., a computer (941)). The electronic device can display the same screen as the screen displayed on the display of the object of interest (e.g., a computer (941)) in an area of ​​the virtual object (e.g., a virtual object (951)) corresponding to the display of the object of interest (e.g., a computer (941)). Accordingly, even if the user enters the virtual space (900), the user can receive the same screen as the screen output from the object of interest (e.g., computer (941)) through a virtual object (e.g., virtual object (951)) corresponding to the object of interest (e.g., computer (941)) in the virtual space (900).

[0176] In one embodiment, when a character is recognized on the surface of an object of interest (e.g., a memo pad (942)), the electronic device may output the recognized character to a virtual object (e.g., a virtual object (952)) corresponding to the object of interest (e.g., a memo pad (942)). For example, the electronic device may recognize a character (e.g., optical character recognition (OCR)) in an area corresponding to the object of interest (e.g., a memo pad (942)) in a real space image (920). The electronic device may display the same character as the character recognized on the surface of the object of interest (e.g., a memo pad (942)) in an area of ​​a virtual object (e.g., a virtual object (952)) corresponding to the surface of the object of interest (e.g., a memo pad (942)).

[0177] In one embodiment, the electronic device may arrange a plurality of virtual objects (e.g., virtual objects (951, 952, 953)) corresponding to a plurality of objects of interest (e.g., a computer (941), a memo (942), a memo (943)) in a virtual space (900) so as not to overlap each other. Arranging the virtual objects in a virtual space (900) so as not to overlap each other may indicate that the areas corresponding to each of the virtual objects do not overlap each other from the user's gaze direction.

[0178] The electronic device can generate a plurality of virtual objects (e.g., virtual objects (951, 952, 953)) corresponding to a plurality of objects of interest (e.g., computer (941), memo (942), memo (943)) determined from a real space image (920). The electronic device can arrange the plurality of virtual objects (e.g., virtual objects (951, 952, 953)) so that they do not overlap each other within the virtual space (900).

[0179] In one embodiment, the electronic device may place a virtual object (e.g., virtual object 951) corresponding to an object of interest (e.g., computer 941)) close to a position in the virtual space (900) corresponding to a position of the object of interest (e.g., computer 941) in the real space. For example, the electronic device may use a real space image (920) to construct the virtual space (900) similar to the real space. Here, the position in the virtual space (900) corresponding to the position of the object of interest in the real space may represent a position in the virtual space (900) corresponding to a distance and direction between the user and the object of interest in the real space. In other words, when the object of interest is located at a distance A and a direction B from the user in the real space, the position in the virtual space (900) corresponding to the position of the object of interest in the real space may represent a position at a distance A and a direction B from the user in the virtual space (900).

[0180] In one embodiment, the electronic device may arrange a plurality of virtual objects (e.g., virtual objects (951, 952, 953)) corresponding to a plurality of objects of interest (e.g., computer (941), memo (942), memo (943)) in order of priority of the corresponding objects of interest, such that each virtual object is close to the position of the corresponding object of interest in the real space and the position of the corresponding object of interest in the virtual space. At this time, the electronic device may arrange the plurality of virtual objects (e.g., virtual objects (951, 952, 953)) in order of priority of the corresponding objects of interest without overlapping each other. The electronic device may designate priorities among the plurality of objects of interest (e.g., computer (941), memo (942), memo (943)). The priorities of the objects of interest may be determined based on the object types. For example, the object type of the computer may have a higher priority than the object type of the memo. The electronic device may arbitrarily designate priorities for a plurality of objects of interest having the same object type. Referring to FIG. 9, the electronic device may preferentially place a virtual object (951) corresponding to a computer (941) having the highest priority among objects of interest in the virtual space (900). At this time, the electronic device may place the virtual object (951) at a location in the virtual space (900) corresponding to the location of the computer (941) in the real space. In addition, the electronic device may place a virtual object (952) corresponding to a memo (942) having the next highest priority among objects of interest in the virtual space (900). At this time, the electronic device may place the virtual object (952) close to a location in the virtual space (900) corresponding to the location of the memo (942) in the real space without overlapping with a virtual object (951) previously placed in the virtual space (900).Since the electronic device is arranged in such a way that a computer (941) and a memo (942) overlap each other in a real space, a virtual object (952) can be arranged in a surrounding area of ​​the virtual object (951) in a virtual space (900). Accordingly, a user can simultaneously check the characters displayed on the memo (942) through the virtual object (952) while looking at the screen of the computer (941) through the virtual object (951) in the virtual space (900).

[0181] FIG. 10 is a diagram illustrating a process of determining an object of interest and placing the determined object of interest in a virtual space based on a living room mode of an electronic device according to various embodiments.

[0182] In one embodiment, the electronic device may enter a living room mode. The electronic device may identify external objects from a real-space image (1020) acquired through a camera. The electronic device may determine, among the external objects identified from the real-space image (1020), an external object (e.g., a desk (1041), a TV (1042)) having an object type corresponding to the living room mode as an object of interest.

[0183] In one embodiment, the electronic device may generate virtual objects (1051, 1052) corresponding to objects of interest, a desk (1041) and a TV (1042), respectively. The electronic device may load 3D data stored for the desk (1041) and the TV (1042) from a database, and generate virtual objects (1051) and virtual objects (1052) corresponding to the desk (1041) and the TV (1042), respectively, based on the loaded 3D data. The electronic device may place the generated plurality of virtual objects (1051, 1052) in a virtual space (1000). As described above, when the electronic device places the plurality of virtual objects (1051, 1052) in the virtual space (1000), the plurality of virtual objects (1051, 1052) may be placed so that they do not overlap each other in the virtual space (1000). The electronic device may arrange multiple virtual objects (1051, 1052) in the order of priority of the corresponding objects of interest. For example, the electronic device may designate a TV (1042) as having a higher priority than a desk (1041), in which case the virtual object (1052) corresponding to the TV (1042) may be arranged with priority over the virtual object (1051) corresponding to the desk (1041). The electronic device may preferentially arrange the virtual object (1052) corresponding to the TV (1042) in the virtual space (1000). The electronic device may arrange the virtual object (1052) at a location in the virtual space (1000) that corresponds to the location of the TV (1042) in the real space. In addition, the electronic device can place a virtual object (1051) corresponding to the desk (1041) close to a position in the virtual space (1000) corresponding to the position of the desk (1041) in the real space, without overlapping with a virtual object (1052) previously placed in the virtual space (1000). Furthermore, the electronic device can establish wireless communication with the TV (1042).The electronic device can receive information about a screen displayed on the display of the TV (1042) from the TV (1042). The electronic device can display the same screen displayed on the display of the TV (1042) in an area of ​​a virtual object (1052) corresponding to the display of the TV (1042).

[0184] FIG. 11 is a diagram illustrating a process of updating the shape and position of a virtual object placed in a virtual space over time according to various embodiments.

[0185] In one embodiment, the electronic device can update the shape and position of a virtual object corresponding to the object of interest by comparing the object of interest in the real space image of the current frame with the object of interest in the real space image of the next frame. The electronic device can update the shape and position of the virtual object placed in the virtual space over time. The following describes a process in which the electronic device displays a virtual object corresponding to the object of interest in the real space image of the current frame and then updates the shape and position of the virtual object according to the real space image of the next frame.

[0186] First, in operation (1110), the electronic device can determine whether the (digital) asset of the object of interest has changed based on the real-space image of the next frame. Here, the asset of the object of interest may represent a digital material that constitutes the object of interest. For example, a change in the asset of the object of interest may indicate that the object of interest has changed into a different object. A non-change in the asset of the object of interest may indicate that the object of interest has not changed into a different object, but that a physical change or positional change has occurred in the object of interest.

[0187] In operation (1120), the electronic device may perform asset initialization for the object of interest when the asset of the object of interest changes. In other words, when the asset of the object of interest changes, the electronic device may determine that the object of interest has changed to a different object and regenerate the asset.

[0188] In operation (1130), if the asset of the object of interest does not change, the electronic device may determine whether a physical change has occurred in the object of interest and apply a motion effect to a virtual object corresponding to the object of interest. For example, referring to FIG. 9, a physical change may occur in which a memo pad (943), which is an object of interest, shakes in the wind. As another example, a physical change may occur in which a ball, which is an object of interest, bounces on the floor. In this case, the electronic device may apply a motion effect according to a similar physical change to the virtual object according to the physical change in the object of interest while maintaining the asset of the object of interest. In other words, the electronic device may apply a motion effect of shaking in the wind to a virtual object (953) corresponding to the memo pad (943) in a virtual space, and may apply a motion effect of bouncing on the floor to a virtual object corresponding to the ball.

[0189] In operation (1140), the electronic device can provide a visual effect to a virtual object corresponding to the object of interest based on whether an event occurs based on a user input. The electronic device can determine whether an event occurs based on a user input in a virtual space. For example, a user can generate an event of writing a character in an area corresponding to a virtual object corresponding to the object of interest in the virtual space. In this case, the electronic device can determine that an event based on the user input has occurred and display the character entered by the user in an area corresponding to the virtual object corresponding to the object of interest. The event based on the user input is not limited to the example above, and can generate various events, such as, for example, a user selecting an interface object in an area of ​​a virtual object corresponding to the display area of ​​the object of interest.

[0190] In operation (1150), the electronic device can update the location and shape of the object of interest. The electronic device can track changes in the location and shape of the object of interest in the real space through the real space image of the next frame. The electronic device can update the location and shape of the object of interest based on the tracked information. The electronic device can change the location and shape of a virtual object corresponding to the object of interest in the virtual space based on changes in the location and shape of the object of interest in the real space.

[0191] In operation (1160), the electronic device may render a virtual object corresponding to the object of interest. The electronic device may render the virtual object corresponding to the object of interest and then display it in a virtual space.

[0192] FIG. 12 is a diagram illustrating a process for determining whether to place a virtual object corresponding to a companion animal in a virtual space according to various embodiments.

[0193] In one embodiment, when the electronic device enters the pet mode, it may compare the size of the real space (1220) with the size of the virtual space (1200) to determine whether to place a virtual object (1251) corresponding to the pet (1241) identified as an external object in the virtual space (1200).

[0194] In one embodiment, the movement of the companion animal (1241) is unpredictable, which may pose a threat to the user wearing the electronic device. Therefore, the electronic device needs to continuously provide the user wearing the electronic device with the location of the companion animal (1241) through virtual space (1200). The electronic device may enter companion animal mode and place a virtual object (1251) corresponding to the companion animal (1241) in the virtual space (1200).

[0195] However, since the pet (1241) is less likely to pose a threat to the user when the electronic device is far away from the user, providing the location of the pet (1241) to the user may actually be distracting to the user. Accordingly, the electronic device may selectively place a virtual object (1251) corresponding to the pet (1241) in the virtual space (1200).

[0196] In one embodiment, when an electronic device detects a pet (1241) in a real space (1220), the electronic device can calculate the location of the pet (1241) in the real space (1220). Based on the location of the pet (1241) in the real space (1220), the electronic device can determine whether to place a virtual object (1251) corresponding to the pet (1241) in the virtual space (1200). In the present disclosure, “based on” covers “at least based on.”

[0197] More specifically, the electronic device may place the virtual object (1251) corresponding to the pet (1241) in the virtual space (1200) only when the pet (1241) is located in an area of ​​the real space (1220) corresponding to the virtual space (1200) when the size of the real space (1220) is larger than the size of the virtual space (1200). In other words, the electronic device may not place the virtual object (1251) corresponding to the pet (1241) in the virtual space (1200) when the size of the real space (1220) is larger than the size of the virtual space (1200) when the pet (1241) is located outside an area of ​​the real space (1220) corresponding to the virtual space (1200). In other words, since the electronic device only needs to provide attention to the user within the area of ​​the real space (1220) corresponding to the virtual space (1200), there is no need to provide the user with location information of the pet (1241) when the pet (1241) is located outside the area of ​​the real space (1220) corresponding to the virtual space (1200).

[0198] In one embodiment, the electronic device may place a virtual object (1251) corresponding to the pet (1241) in the virtual space (1200) regardless of the location of the pet (1241) when the size of the real space (1220) is smaller than the size of the virtual space (1200).

[0199] FIGS. 13A to 13D are drawings illustrating a process in which an electronic device according to various embodiments changes a screen display method according to a reality level.

[0200] FIG. 13A illustrates a real space image (1320) in which a real space is captured by an electronic device. Referring to FIG. 13, the electronic device can capture a real space image (1320) in which a real space is captured by a camera (e.g., the first camera (265a, 265b) of FIG. 2 or the functional camera (415) of FIG. 4A). The electronic device can identify external objects (e.g., a computer (1341), files (1342a, 1342b), a memo pad (1343), a book (1344), and a stand (1345)) from the real space image (1320). The electronic device can determine the computer (1341), files (1342a, 1342b), the memo pad (1343), the book (1344), and the stand (1345) as objects of interest among the external objects identified from the real space image (1320).

[0201] In one embodiment, an electronic device can change the display method of its screen based on the reality level. The electronic device can create a virtual space that is more similar to a real space as the reality level increases. For example, the reality levels may include a first level, a second level, and a third level, and the reality levels may increase in the order of the first level, the second level, and the third level.

[0202] FIG. 13b illustrates an example of a screen displayed on a display when an electronic device sets the reality level to the first level.

[0203] In one embodiment, the electronic device may set the reality level to the lowest level, Level 1. In this case, the electronic device may display a VR screen on the display. In other words, the electronic device may display a screen that does not reflect the actual space image (1320) captured by the camera. For example, the electronic device may generate a virtual object corresponding to an object of interest in a two-dimensional form. The electronic device may display the virtual object corresponding to the object of interest in the form of an image or an icon. Referring to FIG. 13B, the electronic device may establish communication with a computer (1341) and receive an image displayed on the display of the computer (1341). The electronic device may place the received image (1351) as a virtual object corresponding to the computer (1341) in the virtual space (1350). The electronic device can place icons (1352a, 1352b), icons (1353), icons (1354), and icons (1355) as virtual objects corresponding to files (1342a, 1342b), memos (1343), books (1344), and stands (1345) in a virtual space (1350).

[0204] In one embodiment, the electronic device may display a toggle button on some icons. If the electronic device can change the state of an object of interest placed in a real space, the electronic device may add a toggle button to an icon corresponding to the object of interest. For example, the electronic device may change the state of a stand (1345) (e.g., turned on or turned off) and display a toggle button on an icon (1355), which is a virtual object corresponding to the stand (1345). In this case, if the electronic device receives a user input that selects (or touches) an area corresponding to the toggle button of the icon (1355), the electronic device may change the state of the stand (1345) placed in a real space (e.g., turned on or turned off).

[0205] FIG. 13c illustrates an example of a screen displayed on a display when an electronic device sets the reality level to the second level.

[0206] In one embodiment, the electronic device may set the reality level to a second level, which is an intermediate level. In this case, the electronic device may display an AR screen on the display. In other words, the electronic device may display a screen reflecting a real-space image (1320) on the display.

[0207] In one embodiment, the electronic device may blur a real space image (1320) and display it on the screen. The electronic device may generate a virtual object corresponding to an object of interest in a three-dimensional form. The electronic device may generate a single rendered image (1321) in which virtual objects (e.g., virtual objects (1361, 1362a, 1362b, 1363, 1364, 1365)) corresponding to objects of interest (e.g., a computer (1341), files (1342a, 1342b), a memo pad (1343), a book (1344), a stand (1345)) are displayed. The electronic device may overlay the blurred real space image (1320) and the rendered image (1321) and display them on the screen. FIG. 13C illustrates an example of overlaying a real space image (1320) on a single rendered image (1321) in which multiple virtual objects are displayed, but is not necessarily limited thereto. The electronic device can generate multiple rendered images corresponding to each of the multiple virtual objects, and can also overlay the multiple rendered images with a real space image (1320).

[0208] FIG. 13d illustrates an example of a screen displayed on a display when an electronic device sets the reality level to the third level.

[0209] In one embodiment, the electronic device can set the reality level to the third level, the highest level. In this case, the electronic device can display an AR screen on the display. In other words, the electronic device can display a screen reflecting a real-space image (1320).

[0210] In one embodiment, the electronic device can display on the screen a real space image (1320) without blurring. The electronic device can generate a virtual object corresponding to an external object in a three-dimensional form. The electronic device can generate a single rendered image (1322) in which virtual objects (e.g., virtual objects (1371, 1372a, 1372b, 1373, 1374, 1375)) corresponding to objects of interest (e.g., a computer (1341), files (1342a, 1342b), a memo (1343), a book (1344), a stand (1345)) are displayed. At this time, the electronic device can perform preprocessing on the real space image (1320). For example, the electronic device may blur areas corresponding to objects of interest (e.g., computer (1341), files (1342a, 1342b), memo pad (1343), book (1344), stand (1345)) in the real space image (1320). In addition, the electronic device may blur areas corresponding to external objects of low importance (e.g., area (1381), area (1382)) in the real space image (1320). The electronic device may overlay the rendered image (1322) on the preprocessed real space image (1320) and display it on the screen. For example, the electronic device may determine external objects of interest less than a threshold size among the external objects identified in the real space image (1320) as external objects of low importance.

[0211] Electronic devices according to the various embodiments disclosed in this document may take various forms. Electronic devices may include, for example, portable communication devices (e.g., smartphones), computer devices, portable multimedia devices, portable medical devices, cameras, wearable devices, or home appliances. Electronic devices according to the embodiments of this document are not limited to the aforementioned devices.

[0214] Various embodiments of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

For example, the devices, methods, and components described in the embodiments may be implemented using a general-purpose computer or a special-purpose computer, such as, for example, a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a programmable logic unit (PLU), a microprocessor, or any other device capable of executing instructions and responding to them. The processing device may execute an operating system (OS) and software applications running on the operating system. Furthermore, the processing device may access, store, manipulate, process, and generate data in response to the execution of the software. For ease of understanding, the processing device is sometimes described as being used alone; however, one of ordinary skill in the art will recognize that the processing device may include multiple processing elements and / or multiple types of processing elements. For example, a processing unit may include multiple processors, or a processor and a controller. Other processing configurations, such as parallel processors, are also possible.

[0218] Software may include computer programs, codes, instructions, or a combination of one or more of these, which may configure a processing device to perform a desired operation or may independently or collectively command the processing device. The software and / or data may be permanently or temporarily embodied in any type of machine, component, physical device, virtual equipment, or computer storage medium or device for interpretation by the processing device or for providing instructions or data to the processing device.
