[0028] 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.

[0029] 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)).

[0034] 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.

[0035] The communication module (190) 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).

[0036] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 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.

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. According to 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).

[0038] In one embodiment, 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.

[0039] 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)).

[0040] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is 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 or in addition to executing the function or service by itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that have received 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).

[0041] The electronic device (101) may process the result as is or additionally and provide it as at least part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).

[0042] FIGS. 2A and 2B illustrate an example of a perspective view of a wearable device, according to one embodiment.

[0043] According to one embodiment, the wearable device (200) may have the form of glasses that are wearable on a body part of a user (e.g., head). The wearable device (200) of FIGS. 2A and 2B may be an example of the electronic device (101) of FIG. 1. The wearable device (200) may include a head-mounted display (HMD). For example, the housing of the wearable device (200) may include a flexible material, such as rubber and / or silicone, that is configured to fit closely to a portion of the user's head (e.g., a portion of the face surrounding both eyes). For example, the housing of the wearable device (200) may include one or more straps that are capable of being twined around the user's head, and / or one or more temples that are detachably attachable to the ears of the head.

[0044] Referring to FIG. 2A, according to one embodiment, a wearable device (200) may include at least one display (250) and a frame (295) supporting at least one display (250).

[0045] According to one embodiment, the wearable device (200) can be worn on a part of a user's body. The wearable device (200) can provide augmented reality (AR), virtual reality (VR), or mixed reality (MR) that combines augmented reality and virtual reality to the user wearing the wearable device (200). For example, the wearable device (200) can display a virtual reality image provided from at least one optical device (282, 284) of FIG. 2B on at least one display (250) in response to a user's designated gesture acquired through the motion recognition cameras (260-2, 260-3) of FIG. 2B.

[0047] Referring to FIG. 2B, at least one display (250) can provide the user with visual information transmitted from external light and other visual information distinct from the visual information through a lens included in the at least one display (250). The lens can be formed based on at least one of a Fresnel lens, a pancake lens, or a multi-channel lens. For example, the at least one display (250) can include a first surface (231) and a second surface (232) opposite to the first surface (231). A display area can be formed on the second surface (232) of the at least one display (250). When the user wears the wearable device (200), external light can be transmitted to the user by being incident on the first surface (231) and transmitted through the second surface (232). As another example, at least one display (250) can display an augmented reality image combined with a virtual reality image provided from at least one optical device (282, 284) on a real screen transmitted through external light, in a display area formed on the second surface (232).

A nano-pattern may be formed on at least a portion of the exterior or interior of the at least one waveguide (233, 234). The nano-pattern may be formed based on a grating structure having a polygonal and / or curved shape. Light incident on one end of the at least one waveguide (233, 234) may be propagated to the other end of the at least one waveguide (233, 234) by the nano-pattern. At least one waveguide (233, 234) may include at least one diffractive element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)) and at least one reflective element (e.g., a reflective mirror). For example, at least one waveguide (233, 234) may be arranged within the wearable device (200) to guide a screen displayed by at least one display (250) to the user's eyes. For example, the screen may be transmitted to the user's eyes based on total internal reflection (TIR) ​​occurring within the at least one waveguide (233, 234).

A user wearing the wearable device (200) can view an image displayed on at least one display (250).

[0050] According to one embodiment, the frame (295) may be formed as a physical structure that allows the wearable device (200) to be worn on the user's body. According to one embodiment, the frame (295) may be configured so that, when the user wears the wearable device (200), the first display (250-1) and the second display (250-2) can be positioned corresponding to the user's left and right eyes. The frame (295) may support at least one display (250). For example, the frame (295) may support the first display (250-1) and the second display (250-2) to be positioned corresponding to the user's left and right eyes.

[0051] Referring to FIG. 2A, the frame (295) may include a region (220) that at least partially contacts a part of the user's body when the user wears the wearable device (200). For example, the region (220) of the frame (295) that contacts a part of the user's body may include a region that contacts a part of the user's nose, a part of the user's ear, and a part of the side of the user's face that the wearable device (200) makes contact with. According to one embodiment, the frame (295) may include a nose pad (210) that contacts a part of the user's body. When the wearable device (200) is worn by the user, the nose pad (210) may contact a part of the user's nose. The frame (295) may include a first temple (204) and a second temple (205) that contact a part of the user's body that is distinct from the part of the user's body.

[0052] For example, the frame (295) may include a first rim (201) that surrounds at least a portion of the first display (250-1), a second rim (202) that surrounds at least a portion of the second display (250-2), a bridge (203) that is disposed between the first rim (201) and the second rim (202), a first pad (211) that is disposed along a portion of the edge of the first rim (201) from one end of the bridge (203), a second pad (212) that is disposed along a portion of the edge of the second rim (202) from the other end of the bridge (203), a first temple (204) that extends from the first rim (201) and is fixed to a portion of an ear of the wearer, and a second temple (205) that extends from the second rim (202) and is fixed to a portion of an ear opposite the ear. The first pad (211) and the second pad (212) may be in contact with a portion of the user's nose, and the first temple (204) and the second temple (205) may be in contact with a portion of the user's face and a portion of the user's ear. The temples (204, 205) may be rotatably connected to the rim through the hinge units (206, 207) of FIG. 2B. The first temple (204) may be rotatably connected to the first rim (201) through the first hinge unit (206) disposed between the first rim (201) and the first temple (204). The second temple (205) may be rotatably connected to the second rim (202) through the second hinge unit (207) disposed between the second rim (202) and the second temple (205). According to one embodiment, the wearable device (200) can identify an external object (e.g., a user's fingertip) touching the frame (295) and / or a gesture performed by the external object by using a touch sensor, a grip sensor, and / or a proximity sensor formed on at least a portion of a surface of the frame (295).

[0053] According to one embodiment, the wearable device (200) may include hardwares that perform various functions (e.g., hardwares to be described later based on the block diagram of FIG. 4). For example, the hardwares may include a battery module (270), an antenna module (275), at least one optical device (282, 284), speakers (e.g., speakers 255-1, 255-2), a microphone (e.g., microphones 265-1, 265-2, 265-3), a light-emitting module (not shown), and / or a printed circuit board (PCB) (290) (e.g., a printed circuit board). The various hardwares may be arranged within a frame (295).

[0054] According to one embodiment, the microphones (e.g., microphones 265-1, 265-2, 265-3) of the wearable device (200) may be disposed on at least a portion of the frame (295) to acquire sound signals. A first microphone (265-1) disposed on the bridge (203), a second microphone (265-2) disposed on the second rim (202), and a third microphone (265-3) disposed on the first rim (201) are illustrated in FIG. 2B , but the number and arrangement of the microphones (265) are not limited to the embodiment of FIG. 2B . When the number of microphones (265) included in the wearable device (200) is two or more, the wearable device (200) may identify the direction of the sound signal by using a plurality of microphones disposed on different portions of the frame (295).

[0055] In one embodiment, at least one optical device (282, 284) can project a virtual object onto at least one display (250) to provide various image information to a user. For example, at least one optical device (282, 284) can be a projector. At least one optical device (282, 284) can be disposed adjacent to at least one display (250) or can be included within at least one display (250) as a part of at least one display (250). In one embodiment, the wearable device (200) can include a first optical device (282) corresponding to a first display (250-1) and a second optical device (284) corresponding to a second display (250-2). For example, at least one optical device (282, 284) may include a first optical device (282) disposed at an edge of a first display (250-1) and a second optical device (284) disposed at an edge of a second display (250-2). The first optical device (282) may transmit light to a first waveguide (233) disposed on the first display (250-1), and the second optical device (284) may transmit light to a second waveguide (234) disposed on the second display (250-2).

[0056] In one embodiment, the camera (260) may include a recording camera (260-4), an eye tracking camera (ET CAM) (260-1), and / or motion recognition cameras (260-2, 260-3). The recording camera (260-4), the eye tracking camera (260-1), and the motion recognition cameras (260-2, 260-3) may be positioned at different locations on the frame (295) and may perform different functions. The eye tracking camera (260-1) may output data indicating the position or gaze of the eyes of a user wearing the wearable device (200). For example, the wearable device (200) may detect the gaze from an image including the user's pupils obtained through the eye tracking camera (260-1). The wearable device (200) can identify an object (e.g., a real object and / or a virtual object) focused on by the user using the user's gaze acquired through the gaze tracking camera (260-1). The wearable device (200) that has identified the focused object can execute a function (e.g., gaze interaction) for interaction between the user and the focused object. The wearable device (200) can express a part corresponding to the eye of an avatar representing the user in a virtual space using the user's gaze acquired through the gaze tracking camera (260-1). The wearable device (200) can render an image (or screen) displayed on at least one display (250) based on the position of the user's eyes. For example, the visual quality of a first region related to the gaze within the image and the visual quality (e.g., resolution, brightness, saturation, grayscale, PPI) of a second region distinguished from the first region may be different from each other. The wearable device (200) can obtain an image having visual quality of a first area matching the user's gaze and visual quality of a second area using foveated rendering.For example, if the wearable device (200) supports an iris recognition function, user authentication can be performed based on iris information acquired using the gaze tracking camera (260-1). An example in which the gaze tracking camera (260-1) is positioned toward the user's right eye is illustrated in FIG. 2B, but the embodiment is not limited thereto, and the gaze tracking camera (260-1) may be positioned solely toward the user's left eye, or toward both eyes.

[0057] In one embodiment, the capturing camera (260-4) can capture an actual image or background to be aligned with a virtual image to implement augmented reality or mixed reality content. The capturing camera (260-4) can be used to acquire a high-resolution image based on HR (high resolution) or PV (photo video). The capturing camera (260-4) can capture an image of a specific object existing at a location viewed by the user and provide the image to at least one display (250). The at least one display (250) can display a single image in which information about an actual image or background including the image of the specific object acquired using the capturing camera (260-4) is superimposed on a virtual image provided through at least one optical device (282, 284). The wearable device (200) can compensate for depth information (e.g., the distance between the wearable device (200) and an external object acquired through a depth sensor) using the image acquired through the capturing camera (260-4). The wearable device (200) can perform object recognition through an image acquired using a photographing camera (260-4). The wearable device (200) can perform a function of focusing on an object (or subject) in an image (e.g., auto focus) and / or an optical image stabilization (OIS) function (e.g., anti-shake function) using the photographing camera (260-4). The wearable device (200) can perform a pass-through function to display an image acquired through the photographing camera (260-4) by overlapping at least a portion of a screen representing a virtual space on at least one display (250). In one embodiment, the photographing camera (260-4) can be disposed on a bridge (203) disposed between a first rim (201) and a second rim (202).

[0058] The gaze tracking camera (260-1) can implement more realistic augmented reality by tracking the gaze of a user wearing the wearable device (200) and matching the user's gaze with visual information provided to at least one display (250). For example, when the wearable device (200) looks straight ahead, the wearable device (200) can naturally display environmental information related to the user's front at a location where the user is located on at least one display (250). The gaze tracking camera (260-1) can be configured to capture an image of the user's pupil to determine the user's gaze. For example, the gaze tracking camera (260-1) can receive gaze detection light reflected from the user's pupil and track the user's gaze based on the position and movement of the received gaze detection light. In one embodiment, the gaze tracking camera (260-1) can be positioned at positions corresponding to the user's left and right eyes. For example, the gaze tracking camera (260-1) may be positioned within the first rim (201) and / or the second rim (202) to face the direction in which the user wearing the wearable device (200) is positioned.

[0059] The gesture recognition camera (260-2, 260-3) can recognize the movement of the user's entire body, such as the user's torso, hand, or face, or a part of the body, and thereby provide a specific event on a screen provided on at least one display (250). The gesture recognition camera (260-2, 260-3) can recognize the user's gesture (gesture recognition), obtain a signal corresponding to the gesture, and provide a display corresponding to the signal on at least one display (250). The processor can identify the signal corresponding to the gesture, and perform a designated function based on the identification. The gesture recognition camera (260-2, 260-3) can be used to perform simultaneous localization and mapping (SLAM) for 6 degrees of freedom pose (6 dof pose) and / or a spatial recognition function using a depth map. The processor may perform gesture recognition and / or object tracking functions using the motion recognition cameras (260-2, 260-3). In one embodiment, the motion recognition cameras (260-2, 260-3) may be positioned on the first rim (201) and / or the second rim (202).

[0060] The camera (260) included in the wearable device (200) is not limited to the above-described gaze tracking camera (260-1) and motion recognition cameras (260-2, 260-3). For example, the wearable device (200) can identify an external object included in the FoV using a camera positioned toward the user's FoV. The wearable device (200) can identify an external object based on a sensor for identifying the distance between the wearable device (200) and the external object, such as a depth sensor and / or a time of flight (ToF) sensor. The camera (260) positioned toward the FoV can support an autofocus function and / or an optical image stabilization (OIS) function. For example, the wearable device (200) may include a camera (260) (e.g., a face tracking (FT) camera) positioned toward the face to obtain an image including the face of a user wearing the wearable device (200).

[0061] Although not shown, in one embodiment, the wearable device (200) may further include a light source (e.g., an LED) that emits light toward a subject (e.g., a user's eyes, face, and / or an external object within the FoV) being photographed using the camera (260).

[0084] According to one embodiment, one or more instructions (or commands) representing operations and / or actions to be performed on data by the processor (410) of the wearable device (200) may be stored in the memory (415) of the wearable device (200). A set of one or more instructions may be referred to as firmware, an operating system, a process, a routine, a sub-routine, and / or an application. For example, the wearable device (200) and / or the processor (410) may perform at least one of the operations according to the embodiments described below when a set of a plurality of instructions distributed in the form of an operating system, firmware, a driver, and / or an application is executed. Hereinafter, the fact that an application is installed in a wearable device (200) may mean that one or more instructions provided in the form of an application are stored in a memory (415), and that the one or more applications are stored in a format executable by the processor (410) (e.g., a file having an extension specified by the operating system of the wearable device (200)). As an example, an application may include a program and / or a library related to a service provided to a user.

[0085] Referring to FIG. 4, programs installed in the wearable device (200) may be classified into one of different layers, including an application layer (440), a framework layer (450), and / or a hardware abstraction layer (HAL) (480), based on the target. For example, programs (e.g., modules or drivers) designed to target the hardware of the wearable device (200) (e.g., the display (420), the camera (425), and / or the sensor (430)) may be classified within the hardware abstraction layer (480). The framework layer (450) may be referred to as an XR framework layer in that it includes one or more programs for providing an XR (extended reality) service. For example, FIG. 4 illustrates layers being divided within the memory (415), the layers may be logically divided. However, the present invention is not limited thereto. Depending on the embodiment, the layers may be stored in a designated area within the memory (415).

[0086] For example, within the framework layer (450), programs designed to target at least one of the hardware abstraction layer (480) and / or the application layer (440) (e.g., a position tracker (471), a space recognizer (472), a gesture tracker (473), and / or an eye tracker (474), a face tracker (475)) may be classified. Programs classified within the framework layer (450) may provide an executable API (application programming interface) based on other programs.

[0087] For example, within the application layer (440), programs designed to target users controlling wearable devices (200) may be classified. Examples of programs classified into the application layer (440) include, but are not limited to, an XR (extended reality) system UI (user interface) and / or an XR application (442). For example, programs (e.g., software applications) classified into the application layer (440) may call an API (application programming interface) to cause execution of functions supported by programs classified into the framework layer (450).

[0088] For example, the wearable device (200) may display one or more visual objects on the display (420) for performing interaction with a user for using a virtual space based on the execution of the XR system UI (441). A visual object may refer to an object that can be deployed within a screen for transmitting and / or interacting with information, such as text, an image, an icon, a video, a button, a checkbox, a radio button, a text box, a slider, and / or a table. A visual object may be referred to as a visual guide, a virtual object, a visual element, a UI element, a view object, and / or a view element. The wearable device (200) may provide a service for controlling functions available within a virtual space to the user based on the execution of the XR system UI (441).

[0089] Referring to FIG. 4, a lightweight renderer (443) and / or an XR plug-in (444) are illustrated as being included within the XR system UI (441), but are not limited thereto. For example, the XR system UI (441) may cause execution of functions supported by the lightweight renderer (443) and / or the XR plug-in (444) included within the framework layer (450).

[0090] For example, the wearable device (200) may obtain resources (e.g., APIs, system processes, and / or libraries) used to define, create, and / or execute a rendering pipeline that allows partial changes based on the execution of a lightweight renderer (443). The lightweight renderer (443) may be referred to as a lightweight render pipeline in terms of defining a rendering pipeline that allows partial changes. The lightweight renderer (443) may include a renderer built prior to the execution of a software application (e.g., a prebuilt renderer). For example, the wearable device (200) may obtain resources (e.g., APIs, system processes, and / or libraries) used to define, create, and / or execute an entire rendering pipeline based on the execution of an XR plug-in (444). The XR plugin (444) may be referred to as an open XR native client from the perspective of defining (or configuring) the entire rendering pipeline.

[0091] For example, the wearable device (200) may display a screen representing at least a portion of a virtual space on the display (420) based on the execution of the XR application (442). The XR plug-in (444-1) included in the XR application (442) may be referenced by the XR plug-in (444) of the XR system UI (441). Descriptions of the XR plug-in (444-1) that overlap with the description of the XR plug-in (444) may be omitted. The wearable device (200) may cause the execution of the virtual space manager (451) based on the execution of the XR application (442).

[0092] According to one embodiment, the wearable device (200) may provide a virtual space service based on the execution of the virtual space manager (451). For example, the virtual space manager (451) may include a platform (e.g., an Android platform) for supporting the virtual space service. The wearable device (200) may display the posture of a virtual object representing the user's posture rendered using data acquired through the sensor (430) based on the execution of the virtual space manager (451) on the display. The virtual space manager (451) may be referred to as a composition presentation manager (CPM).

[0093] For example, the virtual space manager (451) may include a runtime service (452). As an example, the runtime service (452) may be referred to as an OpenXR runtime module. The wearable device (200) may be used to provide at least one of a pose prediction function, a frame timing function, and / or a spatial input function to a user through the wearable device (200) based on the execution of the runtime service (452). As an example, the wearable device (200) may be used to perform rendering for a virtual space service to a user based on the execution of the runtime service (452). For example, an application (e.g., unity or an OpenXR native application) may be implemented based on the execution of the runtime service (452).

[0094] For example, the virtual space manager (451) may include a pass-through manager (453). Based on the execution of the pass-through manager (453), the wearable device (200) may display a screen representing a virtual space on the display (420), while another screen representing an actual space acquired through the camera (425) may be superimposed on at least a portion of the screen.

[0095] For example, the virtual space manager (451) may include an input manager (454). Based on the execution of the input manager (454), the wearable device (200) may identify data (e.g., sensor data) acquired by executing one or more programs included in the recognition service layer (470). The wearable device (200) may initiate execution of at least one of the functions of the wearable device (200) using the acquired data.

[0096] For example, the perception abstract layer (460) can be used for data exchange between the virtual space manager (451) and the perception service layer (470). From the perspective of being used for data exchange between the virtual space manager (451) and the perception service layer (470), the perception abstract layer (460) can be referred to as an interface. For example, the perception abstract layer (460) can be referenced as OpenPX. The perception abstract layer (460) can be used for a perception client and a perception service.

[0097] According to one embodiment, the recognition service layer (470) may include one or more programs for processing data acquired from a sensor (430) (or a camera (425)). The one or more programs may include at least one of a position tracker (471), a space recognizer (472), a gesture tracker (473), an eye tracker (474), and / or a face tracker (475). The type and / or number of the one or more programs included in the recognition service layer (470) are not limited to those illustrated in FIG. 4.

[0098] For example, the wearable device (200) can identify the pose of the wearable device (200) using the sensor (430) based on the execution of the position tracker (471). The wearable device (200) can identify the 6 degrees of freedom pose (6 dof pose) of the wearable device (200) using data acquired using the camera (425) and the IMU based on the execution of the position tracker (471). The position tracker (471) can be referred to as a head tracking (HeT) module.

[0099] For example, the wearable device (200) may be used to construct a three-dimensional virtual space around the wearable device (200) (or a user of the wearable device (200)) based on the execution of the space recognizer (472). The wearable device (200) may reconstruct the three-dimensional surroundings of the wearable device (200) using data acquired using the camera (425) based on the execution of the space recognizer (472). The wearable device (200) may identify at least one of a plane, a slope, and stairs based on the three-dimensionally reconstructed surroundings of the wearable device (200) based on the execution of the space recognizer (472). The space recognizer (472) may be referred to as a scene understanding (SU) module.

[0100] For example, the wearable device (200) may be used to identify (or recognize) a pose and / or gesture of a hand of a user of the wearable device (200) based on the execution of the gesture tracker (473). As an example, the wearable device (200) may identify a pose and / or gesture of a hand of a user using data acquired from a sensor (430) based on the execution of the gesture tracker (473). As an example, the wearable device (200) may identify a pose and / or gesture of a hand of a user based on data (or images) acquired using a camera based on the execution of the gesture tracker (473). The gesture tracker (473) may be referred to as a hand tracking (HaT) module and / or a gesture tracking module.

[0101] For example, the wearable device (200) may identify (or track) eye movements of a user of the wearable device (200) based on the execution of the gaze tracker (474). As an example, the wearable device (200) may identify eye movements of the user using data acquired from at least one sensor based on the execution of the gaze tracker (474). As an example, the wearable device (200) may identify eye movements of the user based on data acquired using a camera (e.g., the gaze tracking camera (260-1) of FIGS. 2A and 2B) and / or an infrared light emitting diode (IR LED) based on the execution of the gaze tracker (474). The gaze tracker (474) may be referred to as an eye tracking (ET) module and / or a gaze tracking module.

[0102] For example, the recognition service layer (470) of the wearable device (200) may further include a face tracker (475) for tracking the user's face. For example, the wearable device (200) may identify (or track) the movement of the user's face and / or the user's expression based on the execution of the face tracker (475). The wearable device (200) may estimate the user's expression based on the movement of the user's face based on the execution of the face tracker (475). As an example, the wearable device (200) may identify the movement of the user's face and / or the user's expression based on data (e.g., an image) acquired using a camera based on the execution of the face tracker (475).

[0103] For the embodiments described below, the wearable device (200) of FIG. 4 may be referenced. For example, the embodiments described below may be performed by the processor (410) of the wearable device (200) of FIG. 4.

[0104] Figure 5a illustrates an exemplary virtual space displayed via a display. Figure 5b illustrates an example of an application within the virtual space displayed according to the user's gaze direction. Figures 5c and 5d illustrate exemplary virtual spaces for executing at least one application.

[0105] Referring to FIGS. 5A, 5B, 5C, and 5D, the wearable device (200) may include a camera (e.g., camera 425 of FIG. 4) positioned in front of the user (510) when the device is worn by the user (510). The front of the user (510) may include the head of the user (510) and / or the direction in which the gaze of the user (510) is directed. According to one embodiment, the wearable device (200) may include a sensor (e.g., sensor 430 of FIG. 4) for identifying motion of the head of the user (510) and / or the wearable device (200) when the device is worn by the user (510).

[0106] A processor of a wearable device (200) (e.g., processor (410) of FIG. 4) may identify an angle of the wearable device (200) based on data from a sensor (430). In order to provide a user interface (UI) based on virtual reality (VR), augmented reality (AR), and / or mixed reality (MR) to a user (510) wearing the wearable device (200), the processor (410) may control a camera (425) and / or a sensor (430). The UI may be related to a metaverse service provided by the wearable device (200), and / or a server connected to the wearable device (200), and / or a notification service.

[0107] According to one embodiment, the processor (410) may execute functions related to augmented reality (AR) and / or mixed reality (MR). When the user (510) wears the wearable device (200), the processor (410) may include at least one lens positioned adjacent to the eyes of the user (510). Ambient light passing through the lens may be combined (or mixed) with light emitted from a display of the wearable device (200) (e.g., display (420) of FIG. 4). A display area of ​​the display (420) may be formed within the lens through which the ambient light passes. Since the processor (410) combines the ambient light and the light emitted from the display (420), the user (510) can see an image that is a mixture of a real object recognized by the ambient light and a virtual object formed by the light emitted from the display (420).

[0108] According to one embodiment, a wearable device (200) may perform functions related to video see-through (VST) and / or virtual reality (VR). When a user (510) wears the wearable device (200), the wearable device (200) may include a housing that covers the eyes of the user (510). In the state, the wearable device (200) may include a display (420) disposed on a first surface facing the eyes (e.g., the first surface (310) of FIG. 3A). The wearable device (200) may include a camera (425) (or cameras (260-7, 260-8, 260-9, 260-10, 260-11, 260-12) of FIG. 3B) disposed on a second surface opposite to the first surface (e.g., the second surface (320) of FIG. 3A). Using the camera (425), the processor (410) may acquire frame images including ambient light. The processor (410) may output the frame images to a display (420) disposed on the first surface, thereby allowing a user (510) to recognize the ambient light through the display (420). A display area of ​​the display (420) disposed on the first surface may be formed by one or more pixels included in the display (420). The processor (410) can synthesize a virtual object within frame images output through the display (420) to enable the user (510) to recognize the virtual object together with a real object recognized by ambient light.

[0109] According to one embodiment, the wearable device (200) can provide a user experience based on mixed reality (MR) by utilizing a virtual space. The processor (410) of the wearable device (200) can recognize an external space (e.g., a real space) in which the wearable device (200) is included, and generate a virtual space mapped to the external space. The spatial recognition performed by the processor (410) can include simultaneous localization and mapping (SLAM) and / or spatial mapping (e.g., scene understanding).

[0110] According to one embodiment, the processor (410) may display (or provide) a virtual space occupying the screen of the display (420) through the display (420). For example, the processor (410) may provide a virtual space including at least one virtual object through the display (420). The processor (410) may switch the virtual space occupying the screen to another virtual space based on a user input through the at least one virtual object and / or at least one visual object within the virtual space.

[0111] According to one embodiment, the processor (410) may display a first virtual space (501) corresponding to a first application through the display (420). For example, the first virtual space (501) may be referred to as a home space for executing at least one application. The display (420) may provide the user (510) with at least one virtual object and / or at least one visual object displayed within the first virtual space (501).

[0112] For example, the processor (410) may display a first virtual space (501) through the display (420) based on identifying an input from the user (510) regarding the start of a service regarding a virtual space. The user (510) (or an avatar corresponding to the user (e.g., a visual object (810) of FIG. 8A)) may execute at least one of a plurality of applications that can be provided through the wearable device (200) within the first virtual space (501).

[0113] For example, the processor (410) may provide a plurality of virtual spaces. For example, the processor (410) may provide not only a first virtual space (501), but also a second virtual space (502), a third virtual space (503), and a fourth virtual space (504). The virtual spaces (502, 503, 504) may each correspond to applications running within the first virtual space (501). For example, the second virtual space (502) may be a virtual space provided by a second application based on the execution of the second application. For example, although not shown, the third virtual space (503) may be a space provided by a third application running within the first virtual space (501). The fourth virtual space (504) may be a space provided by a fourth application running within the first virtual space (501).

[0114] According to one embodiment, the processor (410) may, based on identifying at least one application running within a virtual space, display at least one virtual object (520) for entry into another virtual space corresponding to the at least one application through the display (420).

[0115] For example, the processor (410) may, based on identifying an input for executing a second application while a first virtual space (501) corresponding to a first application is displayed on the display (420), display a first virtual object (521) for entering a second virtual space (502) corresponding to the second application within the first virtual space (501). For example, the processor (410) may, in response to an input for executing the second application, display a first virtual object (521) for entering a second virtual space (502) corresponding to the second application within a screen (e.g., screen (532) of FIG. 5D) displayed through the display (420).

[0116] Referring to FIGS. 5A and 5B, the processor (410) may display a portion of the first virtual space (501) through the display (420) based on the direction in which the gaze of the user (510) wearing the wearable device (200) is directed. For example, the processor (410) may identify a field of view (FOV) of the user (510) within the first virtual space (501) detected by the sensor (430) based on the direction in which the gaze of the user (510) is directed. The processor (410) may display a screen corresponding to a portion of the first virtual space (501) corresponding to the field of view detected by the sensor (430) through the display. For example, the processor (410) may identify an angle of view corresponding to the direction (551) detected by the sensor (430) based on the direction (551) toward which the user's gaze is directed. The processor (410) may display, through the display (420), an area (501a) of the first virtual space (501) that is displayable by the angle of view based on the identification of the angle of view corresponding to the direction (551). At least a portion of an area (501b) extending from the area (501a) of the first virtual space (501) may be displayed through the display (420) according to the movement of the user's gaze.

[0117] For example, based on the direction (551) of the user's (510) gaze, the processor (410) may display, through the display (420), a first virtual object (521) for entering a second virtual space (502) corresponding to a second application in a first virtual space (501), and a second virtual object (522) for entering a third virtual space (503) corresponding to a third application. For example, when the direction of the user's (510) gaze changes from the direction (551) to the direction (552) as the user's (510) gaze moves, the processor (410) may display, through the display, a first virtual object (521) for entering a second virtual space (502), and a virtual object for entering a fourth virtual space (504). The above-mentioned embodiments are exemplary and are not limited thereto.

[0118] According to one embodiment, the processor (410) can change the size of at least one virtual object (520) displayed within the first virtual space (501). The processor (410) can change the size of the at least one virtual object (520) within the first virtual space (501) by using a distance related to the motion of the user (510) identified through the sensor (430).

[0119] For example, the processor (410) may, based on identifying an input for executing at least one application within a first virtual space (501), display the at least one application in a first size at a location having a first distance (d1) from a reference point (C) within the first space (501). The reference point (C) may be a location corresponding to a location of a user (510) detected by a sensor (430) and / or a location corresponding to an avatar (e.g., a visual object (810) of FIG. 8A) corresponding to the user (510) within the first virtual space (501). The processor (410) may, based on identifying that the gaze of the user (510) is directed toward the at least one virtual object (520) within the first virtual space (501), display the at least one virtual object at a location that is a second distance (d2) smaller than the first distance (d1) from the reference point (C) and in a second size larger than the first size. The processor (410) may, based on identifying that the gaze of the user (510) is not directed toward the at least one virtual object (520) within the first virtual space (501), display the at least one virtual object at a location that is a third distance (d3) larger than the first distance (d1) from the reference point (C) and in a third size smaller than the first size. However, the above-mentioned embodiments are exemplary and are not limited thereto.

[0120] Referring to FIGS. 5c and 5d, a first virtual space (501) displayed through a display (420) based on the direction (551) of FIG. 5b is exemplarily illustrated through screens (531, 532).

[0121] Referring to FIG. 5C, the display (420) within the screen (531) may display at least one visual object for at least one interface for executing a function of the first application within the first virtual space (501) displayed while the first application is being executed. For example, the processor (410) may display, within the screen (531) displayed while the first application is being executed, a visual object (541) corresponding to a first interface for Internet searching, and a visual object (542) corresponding to a second interface for searching a plurality of images stored in the wearable device (200). The visual objects (541, 542) may be displayed within the first virtual space (501) while the first application is being executed, regardless of the execution of at least one application within the first virtual space (501). For example, visual objects (541, 542) may be referenced as a dash (or dashboard), but the above-mentioned embodiment is exemplary and not limited thereto.

[0122] Referring to FIG. 5D, the display (420) within the screen (532) may display virtual objects (521, 522) within the first virtual space (501) displayed while the first application is being executed, based on a user input for executing a second application and / or a user input for executing a third application. For example, the processor (410) may, in response to a user input for executing a second application identified while the first application is being executed, display a first virtual object (521) for entering a second virtual space (502) corresponding to the second application within the first virtual space (501) corresponding to the first application through the display (420). For example, the processor (410) may, in response to a user input for executing a third application identified while the first application is being executed, display a second virtual object (522) for entering a third virtual space (503) corresponding to the third application at a location spaced apart from the first virtual object (521) within the first virtual space (501) through the display (420).

[0123] According to one embodiment, the processor (410) may, based on identifying at least one application running while the first virtual space (501) is displayed through the display (420), display a visual object (560) for displaying icons corresponding to a plurality of applications including the at least one application. For example, the visual object (560) may include an icon (561) representing a first application, an icon (562) representing a second application, and an icon (563) representing a third application. For example, the icon (561) may be displayed in a different color from the icons (562, 563) to indicate that the first virtual space (501) is being displayed through the display (420) while the first virtual space (501) is being displayed through the display (420). According to one embodiment, the visual object (560) may be referenced as, but is not limited to, one of a menu, a universal menu, a task bar, and a state bar.

[0124] According to one embodiment, the processor (410) may, based on identifying an input for executing a second application and / or an input for executing a third application through the display (420), display visual objects (582, 583) for terminating the second application and / or the third application. For example, the processor (410) may, based on identifying a user input for executing the second application through the display (420), display a visual object (581) for terminating the second application over an icon (562) representing the second application. The processor (410) may, based on identifying an input for terminating the second application received through the visual object (581), remove a first virtual object (521) for entering a second virtual space corresponding to the second application within the first virtual space (501). For example, the processor (410) may, based on identifying a user input for executing a third application through the display (420), display a visual object (582) for terminating the third application on an icon (563) representing the third application. The processor (410) may, based on identifying an input for terminating the third application received through the visual object (582), remove a second virtual object (522) for entering a third virtual space corresponding to the third application within the first virtual space (501).

[0125] According to one embodiment, the processor (410) may store data related to applications executed according to user input in the memory (415). The processor (410) may display a visual object (570) for recommending and / or providing applications that are not stored in the wearable device (200) based on at least a portion of the data. The processor (410) may receive data related to applications through an external electronic device (e.g., the electronic device (102) of FIG. 1) and / or a server (e.g., the server (108) of FIG. 1) or download the applications into the memory (415) based on user input through the visual object (570).

[0126] Hereinafter, an example is described in which the first virtual space (501) is converted into the virtual space provided by at least one application through at least one virtual object (520) for entry into the virtual space provided by at least one application from the first virtual space (501).

[0127] Figures 6a, 6b, and 6c illustrate examples of virtual space transitions.

[0128] In the following, redundant descriptions of configurations having the same reference numerals as those described above in FIGS. 5a to 5d are omitted.

[0129] Referring to FIG. 6A, a screen (631) displayed through the display (420) may be provided based on a direction (651) toward which a user's (510) gaze is directed. According to one embodiment, referring also to FIG. 5A, based on the direction (651), a first visual object (521) may be moved from a position corresponding to a third distance (d3) within the first virtual space (501) to a position corresponding to a first distance (d1), or may be moved from a position corresponding to the first distance (d1) to a position corresponding to a second distance (d2). For example, the processor (410) may expand the size of the first visual object (521) displayed through the display (420) based on the direction (651) toward which a user's gaze is directed.

[0130] According to one embodiment, the processor (410) may display, through the display (420), a first virtual object (521) including a closed surface (521a) representing a portion of a second virtual space (502) provided from a second application, based on a view angle within the first virtual space (501) identified by the sensor (430). For example, the processor (410) may, based on identifying a user input for executing a second application through the display (420), display a virtual object (521) including a closed surface (521a) on which an image (521b) displaying a part of a second virtual space (502) corresponding to the second application is arranged within the first virtual space (501). Through the image (521b), the first virtual object (521) may represent information related to the second virtual space (502) provided by the second application and / or visual objects within the second virtual space (502).

[0131] Referring to FIGS. 6A and 6B, the processor (410) may expand the size of a first visual object (521) within a first virtual space (501) based on a direction (651) of the user's (510) gaze and a motion of the user (510). For example, the processor (410) may expand the size of an image (521b) included in the first visual object (521) through the display (420) while identifying a user input for entering a second virtual space (502) from the first virtual space (501) through the first virtual object (521). For example, the processor (410) may remove a closed surface (521a) of a first visual object (521) within a screen (632) provided while identifying a user input for entering a second virtual space (502) from a first virtual space (501) through a first virtual object (521). For example, the user input for entering a second virtual space (502) from a first virtual space (501) through a first virtual object (521) may include, but is not limited to, a movement of the user (510) in a direction (651) toward which the user's (510's) gaze is directed, or a staring of the user (510) in the direction (651) for a specified period of time or longer.

[0132] Referring to FIG. 6c, an exemplary screen (633) provided after entering a second virtual space (502) corresponding to a second application through a first virtual object (521) is illustrated. The processor (410) may display the second virtual space (502) on the display (420) based on an input for transitioning to the second virtual space (502) through the first virtual object (521).

[0133] For example, the input for switching to the second virtual space (502) through the first virtual object (521) may include, but is not limited to, the direction of the user's (510) gaze detected by the sensor (430) of the wearable device (200) (e.g., the direction (651) of FIG. 5A) and / or the motion of the user (510). For example, the input for switching to the second virtual space (502) through the first virtual object (521) may include, but is not limited to, a designated utterance of the user (510) for switching spaces and / or a gesture for pressing or selecting a visual object (e.g., a button or an image corresponding to the first virtual object (521)) formed for switching spaces displayed through the display (420). For example, when the input for switching to the second virtual space (502) through the first virtual object (521) is based on the user's motion, the input provided through the display (420) The screen can be switched from screen (631) to screen (633) via screen (632). For example, if the input for switching to the second virtual space (502) via the first virtual object (521) is based on a designated user gesture (e.g., a click), the screen provided via the display (420) can be switched directly from screen (631) to screen (633).

[0134] According to one embodiment, in response to identifying a transition to a second virtual space (502), the processor (410) may display a third virtual object (523) for entering a first virtual space (501) on the display (420). For example, based on an input for transitioning to the second virtual space (502) through the first virtual object (521), the processor (410) may display a second virtual space (502) including a third virtual object (523) for transitioning to the first virtual space (501) on the display (420). For example, in response to identifying a transition to the second virtual space (502), the processor (410) may display a third virtual object (523) corresponding to a first application that is being executed, and a fourth virtual object (524) corresponding to the third application, on the display (420).

[0135] According to one embodiment, in response to identifying a transition to a second virtual space (502), the processor (410) may display a third virtual object (523) corresponding to the first application and a fourth virtual object (524) corresponding to the third application on both ends of a screen (633) provided through the display (420) on which the second virtual space (502) is displayed. For example, in response to identifying a transition to a second virtual space (502), the processor (410) may display a third virtual object (623) and a fourth virtual object (634) in areas (633a, 633b) disposed on both ends of a screen (633) provided through the display (420) on which the second virtual space (502) is displayed. The third virtual object (623) may be a virtual object for entering a first virtual space (501) provided through the first application. The fourth virtual object (634) may be a virtual object for entering a third virtual space (503) provided through a third application. According to one embodiment, the virtual objects displayed in the areas (633a, 633b) of the screen (633) provided through transition to the second virtual space (502) may be virtual objects corresponding to applications interacted with through input of the user (510), but are not limited thereto.

[0136] According to the above-described embodiment, the processor (410) of the wearable device (200) can provide an immersive user experience to the user (510) based on an input for transitioning from a first virtual space (501) to a second virtual space (502) through a first virtual object (521). In response to identifying a transition to the second virtual space (502), the processor (410) can display a third virtual object (523) corresponding to a first application on both ends of a screen (633) provided through the display (420) on which the second virtual space (502) is displayed, thereby increasing the immersion of the user (510).

[0137] Figure 7 is a flow chart showing the operation of an exemplary wearable device for transitioning a virtual space.

[0138] The operations of FIG. 7 may be performed by the electronic device (101) and / or processor (120) of FIG. 1, the wearable device (200) of FIG. 2A, the wearable device (300) of FIG. 3A, the wearable device (200) executing the spatial recognizer (472) of FIG. 4, and / or the processor (410).

[0139] Referring to FIG. 7, in operation (701), the processor of the wearable device may identify at least one application running while a first virtual space corresponding to a first application (e.g., the first virtual space (501) of FIG. 5A) is displayed. For example, the processor may display the first virtual space through the display based on identifying the execution of a service for providing the virtual space. The processor may identify at least one application running within the first virtual space while the first application is running.

[0140] In operation (703), the processor of the wearable device may display a first virtual object (e.g., the first virtual object (521) of FIG. 5C) for entry into a second virtual space (e.g., the second virtual space (502) of FIG. 5A) corresponding to the second application within the first virtual space based on identifying an input for executing the second application. For example, the processor may display, within a screen displaying a portion of the first virtual space provided through the display, a first virtual object for entry into the second virtual space provided by the second application based on identifying an input for executing the second application.

[0141] In operation (705), the processor of the wearable device may determine whether an input for transitioning to a second virtual space has been identified. If the processor fails to identify the input for transitioning to the second virtual space (705-No), the processor may continue performing operation (703). For example, the processor may identify the input for transitioning to the second virtual space through the direction of the user's gaze, the user's motion, or a combination thereof.

[0142] In operation (707), the processor of the wearable device may determine whether the distance of the first virtual object is less than a specified distance. For example, referring to FIG. 5A , the processor may determine whether the distance of the first virtual object from the reference point (C) is less than a second distance (d2). If the processor does not determine that the distance of the first virtual object is less than the specified distance (707-No), the processor may perform operation (709).

[0143] In operation (709), the processor of the wearable device may expand the size of the first virtual object displayed within the first virtual space. For example, while identifying that the distance of the first virtual object related to the user's motion in operation (707) is greater than or equal to a specified distance, the processor may expand the size of the first virtual object displayed within the first virtual space through the display.

[0144] In operation (711), the processor of the wearable device may display a second virtual space and a second virtual object (e.g., the third virtual object (523) of FIG. 6C) for entering the first virtual space within the second virtual space. For example, in response to entering the second virtual space, the processor may display the second virtual object for entering the first virtual space within the second virtual space provided through the display. For example, in response to entering the second virtual space, the processor may display the second virtual object for entering the first virtual space at an end of a screen provided through the display.

[0145] Figures 8a, 8b, and 8c illustrate exemplary virtual spaces displayed through a display.

[0146] Referring to FIGS. 8A and 8B , screens (831, 832) provided to a user (510) wearing a wearable device (200) are exemplified. The screens (831, 832) may display a portion of a first virtual space (e.g., the first virtual space (501) of FIG. 5A) provided by a first application.

[0147] Referring to FIG. 8A, the processor (410) may display a virtual object (821) for entering a second virtual space (e.g., the second virtual space (502) of FIG. 5B) provided by a running second application within a screen (831) on which a first virtual space (501) is displayed via a display (420). According to one embodiment, the virtual object (821) may display an image including a visual object (821a) included within the second virtual space (502).

[0148] According to one embodiment, the processor (410) may display a visual object (810) corresponding to a user (510) wearing the wearable device (200) within the first virtual space (501) through the display (420) based on a user input. For example, the visual object (810) may be referred to as an avatar corresponding to the user (510).

[0149] Referring to FIGS. 8A and 8B, based on the motion of the user (510), the position of the visual object (810) corresponding to the user (510) within the first virtual space (501) may change. For example, based on the movement of the user (510), the position of the visual object (810) corresponding to the user (510) within the first virtual space (501) may move. The direction in which the visual object (810) faces the virtual object (821) may change from direction (851) to direction (852). As the direction in which the visual object (810) faces the virtual object (821) changes, the shape of the visual object (821a) within the second virtual space (502) provided by the virtual object (821) may change in response to the direction.

[0150] Referring to FIGS. 8B and 8C, a wearable device (200) worn by a user (510) may be connected to another wearable device (800) worn by another user (80). For example, the processor (410) of the wearable device (200) may, based on identifying an input for execution of a third application, display a virtual object (822) for entry into a third virtual space (e.g., the third virtual space (503) of FIG. 5B) corresponding to the third application through the display (420) of the wearable device (200). A processor in another wearable device (800) may, based on execution of the third application, be connected to the wearable device (200) on which the third application is executed through the third application. For example, another wearable device (800) may display a third space (503) corresponding to the third application through the display of the other wearable device (800) while the third application is running. The other wearable device (800) may display a visual object (860) corresponding to another user (80) wearing the other wearable device (800) within the third space (503). The processor (410) of the wearable device (200) may display a visual object (860) within the third virtual space (503) provided by the third application through a virtual object (822) displayed within the first virtual space (501) while the third application is running.

[0151] For example, another wearable device (200) may display a virtual object (823) for entering a first space (501) corresponding to a first application within a third space (503) through the display of the other wearable device (800). The other wearable device (200) may display a virtual object (810) corresponding to a user (510) within the first space (501) through the virtual object (823).

[0152] According to the above-described embodiment, the processor (410) of the wearable device (200) can provide an immersive user experience to the user (510) through virtual objects that display visual objects within a virtual space other than the virtual space displayed through the display (420). The wearable device (200) can increase the user's sense of immersion by being connected to another wearable device (800) through at least one application.

[0153] Figure 9 illustrates examples of virtual objects placed within a virtual space according to user input.

[0154] Referring to FIG. 9, within a state (900A), a portion of a first virtual space (901) provided by a first application may be displayed through a display (420). While the first application is running, the processor (410) of the wearable device (200) may display virtual objects for transition to a second virtual space (902) provided by a second application, and virtual objects for transition to a third virtual space (903) provided by a third application, on a screen provided through the display (420). The virtual objects may be displayed within areas (901a, 901b) of the first virtual space, respectively.

[0155] Within the state (900B), based on a user input, while the first application is being executed, a fourth application may be executed. The processor (410) of the wearable device (200) may, based on identifying an input for executing the fourth application, create a virtual object for entering a fourth virtual space (904) provided by the fourth application at a first location (p1) within the first virtual space (901). For example, the user input may include, but is not limited to, a user gesture (e.g., a click) for selecting an icon corresponding to the fourth application for executing the fourth application, or a drag-and-drop for placing a visual object corresponding to the fourth application at the first location (p1). According to one embodiment, the processor (410) may maintain placing the virtual object for entry into the third virtual space (903) at the second position (p2) based on identifying that the distance between the first position (p1) of the virtual object for entry into the fourth virtual space (904) and the second position (p2) of the virtual object for entry into the third virtual space (903) is greater than or equal to a reference distance.

[0156] Within the state (900C), the processor (410) may move the virtual object for entry into the third virtual space (903) from the second position (p2) to the third position (p3) based on identifying that the distance between the first position (p1) of the virtual object for entry into the fourth virtual space (904) and the second position (p2) of the virtual object for entry into the third virtual space (903) is less than a reference distance. The third position (p3) may be a position spaced apart from the first position (p1) of the virtual object for entry into the fourth virtual space (904) by the reference distance. Within the state (900C), the processor (410) may identify a user input through the virtual object for entry into the newly created fourth virtual space (904).

[0157] Within the state (900D), in response to identifying entry into the fourth virtual space (904), the processor (410) may display virtual objects in areas (904a, 904b) of the fourth virtual space (904) provided through the display (420), respectively. The virtual objects may include virtual objects for entry into the first virtual space (901) that were displayed through the display (420) prior to entry into the fourth virtual space (904). According to one embodiment, the processor (410) may display virtual objects corresponding to the first application and the second application that were interacted with based on user input prior to entry into the fourth virtual space (904), in areas (904a, 904b) of the fourth virtual space (904) provided through the display (420).

[0158] According to the above-described embodiment, a wearable device may include at least one sensor, a display, a memory for storing instructions, and a processor. The instructions, when executed by the processor, may cause the wearable device to identify at least one application that is running while a first virtual space corresponding to the first application is displayed on the display. The instructions, when executed by the processor, may cause the wearable device to display a first virtual object for entering a second virtual space corresponding to the second application within the first virtual space based on identifying an input for executing a second application. The instructions, when executed by the processor, may cause the wearable device to display the second virtual space on the display based on an input for transitioning to the second virtual space via the first virtual object. The instructions, when executed by the processor, may cause the wearable device to display a second virtual object on the display for entry into the first virtual space in response to identifying a transition to the second virtual space.

[0159] For example, the instructions, when executed by the processor, may cause the wearable device to display a first virtual object having a changeable size within the first virtual space using a distance associated with a motion of the user identified through the at least one sensor. The instructions, when executed by the processor, may cause the wearable device to expand the size of the first virtual object displayed within the first virtual space while identifying an input for transitioning to the second virtual space through the motion of the user. The instructions, when executed by the processor, may cause the wearable device to display the second virtual space on the display based on identifying the distance as being less than a specified distance.

[0160] For example, the instructions, when executed by the processor, may cause the wearable device to change a size of the first virtual object displayed within the first virtual space based on a direction in which the user's gaze is directed, as identified by the at least one sensor. The instructions, when executed by the processor, may cause the wearable device to display the first virtual object within the first virtual space, having a first size, based on a first direction in which the user's gaze is directed. The instructions, when executed by the processor, may cause the wearable device to display the first virtual object within the first virtual space, having a second size smaller than the first size, based on a second direction different from the first direction in which the user's gaze is directed.

[0161] For example, the instructions, when executed by the processor, may cause the wearable device to display a visual object including a plurality of icons, each icon corresponding to a plurality of executable applications, while the first virtual space is displayed on the display. The instructions, when executed by the processor, may cause the wearable device to display a visual object for terminating at least one application among the plurality of applications through the visual object based on identifying the at least one application that is running.

[0162] For example, the instructions, when executed by the processor, may cause the wearable device to display the first visual object, the first visual object including a closed surface representing a portion of the second virtual space provided from the second application, based on a view angle within the first virtual space identified by the at least one sensor.

[0163] For example, the instructions, when executed by the processor, may cause the wearable device to expand a portion of the second virtual space displayed through the virtual object and to remove the closed surface within the first virtual space while identifying an input for transitioning to the second virtual space.

[0164] For example, the instructions, when executed by the processor, may cause the wearable device to display the first virtual object at a first location within the first virtual space. The instructions, when executed by the processor, may cause the wearable device to display a third virtual object for entry into a third virtual space corresponding to the third application at a second location within the first virtual space based on identifying an input for executing a third application. The instructions, when executed by the processor, may cause the wearable device to maintain displaying the third virtual object at the second location based on identifying that a distance between the first location and the second location is greater than or equal to a reference distance. The instructions, when executed by the processor, may cause the wearable device to move the third virtual object to a third location spaced apart from the first location by the reference distance based on identifying that the distance between the first location and the second location is less than a reference value.

[0165] For example, the instructions, when executed by the processor, may cause the wearable device to, in response to identifying a transition to the second virtual space, display the second virtual object and a fourth virtual object for entry into the third virtual space at both ends of a screen provided through the display on which the second virtual space is displayed.

[0166] For example, the instructions, when executed by the processor, may cause the wearable device to display virtual objects corresponding to some of the applications based on identifying that the number of running applications within a screen provided after entering the second virtual space exceeds the number of virtual objects that can be displayed on the display. The instructions, when executed by the processor, may cause the wearable device to display virtual objects corresponding to some of the remaining applications within the second virtual space based on a direction toward which the user's gaze is directed, as identified by the at least one sensor.

[0167] In one embodiment, a method of a wearable device may include an operation of identifying at least one application that is running while a first virtual space corresponding to a first application is displayed on a display of the wearable device. The method may include an operation of displaying a first virtual object for entering a second virtual space corresponding to the second application within the first virtual space based on an input for executing a second application. The method may include an operation of displaying the second virtual space on the display based on an input for transitioning to the second virtual space through the first virtual object. The method may include an operation of displaying a second virtual object for entering the first virtual space on the display in response to identifying a transition to the second virtual space.

[0168] For example, the operation of displaying the first virtual object may include an operation of displaying the first virtual object having a changeable size within the first virtual space by using a distance related to a motion of the user identified through the at least one sensor. The operation of displaying the first virtual object may include an operation of expanding the size of the virtual object displayed within the first virtual space while identifying an input for transitioning to the second virtual space through the motion of the user. The operation of displaying the second virtual space may include an operation of displaying the second virtual space on the display based on identifying the distance as being less than a specified distance.

[0169] For example, the method may further include an operation of changing a size of the first virtual object displayed within the first virtual space based on a direction in which the user's gaze is directed, identified from the at least one sensor. The operation of displaying the first virtual object may include an operation of displaying the first virtual object having a first size within the first virtual space based on a first direction in which the user's gaze is directed. The operation of displaying the first virtual object may include an operation of displaying the first virtual object having a second size smaller than the first size within the first virtual space based on a second direction different from the first direction in which the user's gaze is directed.

[0170] For example, the method may further include an operation of displaying a visual object including a plurality of icons, each corresponding to a plurality of executable applications, while the first virtual space is displayed on the display. The method may further include an operation of displaying a visual object for terminating at least one application among the plurality of applications through the visual object based on identifying the at least one application that is being executed.

[0171] For example, the act of displaying the first visual object may include an act of displaying the first visual object, the first visual object including a closed surface displaying a portion of the second virtual space provided from the second application, based on a view angle within the first virtual space identified by the at least one sensor.

[0172] For example, the action of displaying the first visual object may further include an action of expanding a portion of the second virtual space displayed through the virtual object and removing the closed surface within the first virtual space while identifying an input for transitioning to the second virtual space.

[0173] For example, the operation of displaying the first visual object may include an operation of displaying the first virtual object at a first location within the first virtual space. The method may further include an operation of displaying a third virtual object for entering a third virtual space corresponding to the third application at a second location within the first virtual space based on identifying an input for executing a third application. The method may further include an operation of maintaining the display of the third virtual object at the second location based on identifying that a distance between the first location and the second location is greater than or equal to a reference distance. The method may further include an operation of moving the third virtual object to a third location spaced apart from the first location by the reference distance based on identifying that a distance between the first location and the second location is less than a reference value.

[0174] For example, the action of displaying the second virtual object may include, in response to identifying a transition to the second virtual space, an action of displaying the second virtual object and a fourth virtual object for entry into the third virtual space at both ends of a screen provided through the display on which the second virtual space is displayed.

[0175] For example, the method may further include an operation of displaying virtual objects corresponding to some of the applications based on identifying that the number of running applications within the screen provided after entering the second virtual space exceeds the number of virtual objects that can be displayed on the display. The method may further include an operation of displaying virtual objects corresponding to some of the remaining applications within the second virtual space based on a direction in which the user's gaze is directed, identified through the at least one sensor.

[0176] In one embodiment, a non-transitory computer readable storage medium storing one or more programs may include instructions that, when executed by a processor of a wearable device having a display and at least one sensor, cause the wearable device to identify at least one application that is running while a first virtual space corresponding to the first application is displayed on the display. The one or more programs may include instructions that, when executed by the processor, cause the wearable device to display a first virtual object for entry into a second virtual space corresponding to the second application within the first virtual space based on identifying an input for executing a second application. The one or more programs may include instructions that, when executed by the processor, cause the wearable device to display the second virtual space on the display based on an input for transitioning to the second virtual space via the first virtual object. The one or more programs may include instructions that, in response to identifying a transition to the second virtual space, cause the wearable device to display a second virtual object on the display for entry into the first virtual space.

[0177] For example, the one or more programs may include instructions that, when executed by the processor of the wearable device, cause the wearable device to display a first virtual object having a changeable size within the first virtual space using a distance associated with a motion of the user identified via the at least one sensor. The one or more programs may include instructions that, when executed by the processor of the wearable device, cause the wearable device to expand the size of the virtual object displayed within the first virtual space while identifying an input for transitioning to the second virtual space via the motion of the user. The one or more programs may include instructions that, when executed by the processor, cause the wearable device to display the second virtual space on the display based on identifying the distance as being less than a specified distance.
