[0020] FIG. 1 illustrates an example of a state of use of a wearable device according to an embodiment. Referring to FIG. 1, a wearable device (101) according to an embodiment may include a head-mounted display (HMD) that is wearable on a user's head. Although the external appearance of the wearable device (101) in the form of glasses is illustrated, the embodiment is not limited thereto. An example of the structure of a wearable device (101) that is wearable on a user's head is described with reference to FIGS. 3A to 3B and / or FIGS. 4A to 4B. One or more hardware components included in the wearable device (101) are exemplarily described with reference to FIG. 2. An external electronic device (103) of FIG. 1 may include a terminal owned by a user. For example, the external electronic device (103) may include a smart accessory such as a smartphone, a smartpad, a tablet PC (personal computer), a smartring, and a smartwatch. For example, the external electronic device (103) may include a controller connected to the wearable device (101) via a communication circuit.

[0021] According to one embodiment, a wearable device (101) may perform functions related to augmented reality (AR) and / or mixed reality (MR). Referring to FIG. 1, when a user wears the wearable device (101), the wearable device (101) may include at least one lens positioned adjacent to the user's eyes. The wearable device (101) may combine ambient light passing through the lens with light emitted from a display of the wearable device (101). A display area of ​​the display may be formed within the lens through which the ambient light passes. Since the wearable device (101) combines the ambient light and the light emitted from the display, the user may 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.

[0022] According to one embodiment, a wearable device (101) may perform functions related to video see-through (VST) and / or virtual reality (VR). Referring to FIG. 1, when a user wears the wearable device (101), the wearable device (101) may include a housing that covers the user's eyes. The wearable device (101), in this state, may include a display disposed on a first side facing the eyes. The wearable device (101) may include a camera disposed on a second side opposite the first side. Using the camera, the wearable device (101) may acquire frames containing ambient light. The wearable device (101) may output the frames within the display disposed on the first side, thereby allowing the user to recognize the ambient light through the display. A display area of ​​the display disposed on the first side may be formed by one or more pixels included in the display. The wearable device (101) can synthesize a virtual object within frames output through the display, thereby allowing the user to recognize the virtual object together with a real object recognized by ambient light.

[0023] Referring to FIG. 1, a wearable device (101) according to an embodiment may provide a virtual reality service. For example, the wearable device (101) may display a screen (110) representing the virtual reality service through a display arranged with respect to the eyes of a user wearing the wearable device (101). While displaying the screen (110) representing the virtual reality service, the wearable device (101) may receive biometric data of the user through an external electronic device (103). For example, the biometric data of the user may include data related to the user's blood pressure, body temperature, heart rate, stress index, and / or movement. For example, the biometric data of the user may include data related to the user's movement. According to an embodiment, the wearable device (101) may identify an emergency state of the user based on biometric data received from an external electronic device (103). The wearable device (101) can display parameters related to the biometric data indicating the emergency state by overlapping them on a screen (110) representing the virtual reality service. For example, the wearable device (101) can display a visual object (120) related to parameters related to the biometric data by overlapping them on a screen (110) representing the virtual reality service. For example, the wearable device (101) can display a second visual object that is different from the first visual object (120) and has a smaller size than the first visual object (120). For example, the second visual object can display the first visual object (120) in response to a user's input.For example, the wearable device (101) may display the first visual object (120) based on the user executing a function for displaying the first visual object (120) while the device is identified as a first level emergency condition. For example, the wearable device (101) may, in response to being identified as a second level and / or third level emergency condition, at least temporarily display the first visual object (120) while displaying a screen based on at least one image acquired using a camera.

[0024] According to one embodiment, the wearable device (101) may receive the user's biometric data from the external electronic device (103) while displaying the screen (110) related to the virtual reality service. The wearable device (101) may identify the user's emergency state based on the received user's biometric data. For example, the wearable device (101) may identify the level of the user's emergency state. For example, a first level emergency state among the emergency states may be an emergency state with a relatively low risk compared to a second level emergency state and / or a third level emergency state, which will be described later. For example, a first level emergency state may include a case where parameters included in the biometric data are identified as being below a first threshold. For example, a second level emergency state among the emergency states may include a case where parameters included in the biometric data are identified as being between a first threshold and a second threshold. For example, a third level emergency state among the above emergency states may include a case where parameters included in the biometric data are identified as exceeding a second threshold. According to an embodiment, the wearable device (101) may display a different screen based on the level of the emergency state. For example, while providing a screen (110) representing a virtual reality service, the wearable device (101) may display an image acquired through a camera through the display based on the user's emergency state being identified as the third level. For example, the wearable device (101) may display the image representing the environment around the wearable device (101) based on the identification of the third level emergency state.

[0025] For example, a third level emergency may be when the user's body temperature is identified as being above a first designated body temperature (e.g., 38°C). A third level emergency may be when the user's blood pressure increases above 160 or decreases below 90. A third level emergency may be when the user's maximum heart rate is maintained above a first designated period of time (e.g., 5 minutes). The user's maximum heart rate may be '220 - (the user's age).' A third level emergency may be when an arrhythmia occurs. A third level emergency may be when a high stress index is maintained for a second designated period of time (e.g., 10 minutes). A third level emergency may be when the user identifies a sudden movement. A third level emergency may be when the user identifies a major shock. For example, a Level 3 emergency might be if a virtual reality service has been used for a third specified period of time (e.g., 4 hours).

[0026] For example, a second level emergency state may be when the user's body temperature is above a second designated level (e.g., 37°C) and below a first designated level. For example, a second level emergency state may be when the user's systolic blood pressure decreases from 160 or higher to 160 or lower, and when the diastolic blood pressure changes from 90 or lower to 90 or higher. For example, a second level emergency state may be when the user's heart rate remains above 85% of the user's maximum heart rate for a second designated period of time. For example, a second level emergency state may be when the user's stress index remains at a medium level for a second designated period of time. For example, a second level emergency state may be when the user uses a virtual reality service for a fourth designated period of time (e.g., 2 hours). For example, a first level emergency state may be different from the second level emergency state and / or the second level emergency state. For example, emergency states of Levels 1 to 3 can be identified by parameters set by the user. Emergency states of Levels 1 to 3 are not limited to the examples described above.

[0027] As described above, according to one embodiment, the wearable device (101) can provide a virtual reality service through a display. The wearable device (101) can receive the user's biometric data from an external electronic device (103) while displaying a screen (110) related to the virtual reality service. The wearable device (101) can identify the user's emergency state based on the user's biometric data. The wearable device (101) can identify the level of the user's emergency state. The wearable device (101) can stop providing the screen (110) related to the virtual reality service based on identifying the third level of emergency state. The wearable device (101) can display an image representing the environment around the wearable device (101) acquired through a camera based on identifying the third level of emergency state. The wearable device (101) can provide the user of the wearable device (101) with information about the user's status by displaying different screens based on the level of the user's emergency state. The wearable device (101) can prevent a dangerous situation that may occur to the user of the wearable device (101) by displaying a visual object (120) related to biometric data indicating an emergency state transmitted from an external electronic device (103).

The display area formed by at least one display (350) may be formed on the second surface (332) among the first surface (331) and the second surface (332) of the lens. When the user wears the wearable device (300), external light may be incident on the first surface (331) and transmitted through the second surface (332) to be transmitted to the user. As another example, at least one display (350) may display a virtual reality image to be combined with a real screen transmitted through the external light. The virtual reality image output from at least one display (350) may be transmitted to the user's eyes through one or more hardware (e.g., optical devices (382, 384), and / or at least one waveguide (333, 334)) included in the wearable device (300).

[0043] According to one embodiment, a wearable device (300) may include waveguides (333, 334) that diffract light transmitted from at least one display (350) and relayed by optical devices (382, 384) and transmit the diffracted light to a user. The waveguides (333, 334) may be formed based on at least one of glass, plastic, or polymer. Nanopatterns may be formed on at least a portion of the exterior or interior of the waveguides (333, 334).

The wearable device (300) may analyze the object based on a multi-camera, such as a stereo camera. For the object analysis, the wearable device (300) may execute time-of-flight (ToF) and / or simultaneous localization and mapping (SLAM) supported by the multi-camera. A user wearing the wearable device (300) may view an image displayed on at least one display (350).

[0045] According to one embodiment, the frame may be formed as a physical structure that allows the wearable device (300) to be worn on the user's body. According to one embodiment, the frame may be configured so that, when the user wears the wearable device (300), the first display (350-1) and the second display (350-2) can be positioned corresponding to the user's left and right eyes. The frame may support at least one display (350). For example, the frame may support the first display (350-1) and the second display (350-2) to be positioned corresponding to the user's left and right eyes.

[0046] Referring to FIG. 3A, the frame may include a region (320) that at least partially contacts a portion of the user's body when the user wears the wearable device (300). For example, the region (320) of the frame that contacts a portion of the user's body may include a region that contacts a portion of the user's nose, a portion of the user's ear, and a portion of the side of the user's face that the wearable device (300) makes contact with. According to one embodiment, the frame may include a nose pad (310) that contacts a portion of the user's body.

[0118] The Metaverse is a portmanteau of the English word "meta," meaning "virtual" or "transcendence," and "universe," and refers to a three-dimensional virtual world where social, economic, and cultural activities, like those in the real world, take place. The Metaverse is a concept that is one step more advanced than virtual reality (VR, a cutting-edge technology that allows people to have realistic experiences in a computer-generated virtual world), and has the characteristic of allowing people to engage in social and cultural activities similar to those in the real world, rather than simply enjoying games or virtual reality using avatars. The Metaverse service can provide media content to enhance immersion in the virtual world based on augmented reality (AR), virtual reality environment (VR), mixed reality (MR), and / or extended reality (XR).

[0119] For example, media content provided by a metaverse service may include social interaction content, including avatar-based games, concerts, parties, and / or conferences. For example, the media content may include advertisements, user-created content, and / or information for economic activities such as the sale and / or shopping of products. Ownership of the user-created content may be proven by a blockchain-based non-fungible token (NFT). The metaverse service may support economic activities based on real-world currency and / or cryptocurrency. The metaverse service may provide virtual content linked to the real world, such as digital twins or life logging.

[0120] Figure 12 is an example diagram of a network environment (1201) that provides metaverse services through a server (1210).

[0121] Referring to FIG. 12, a network environment (1201) may include a server (1210), a user terminal (1220) (e.g., a first terminal (1220-1) and a second terminal (1220-2)), and a network connecting the server (1210) and the user terminal (1220). Within the network environment (1201), the server (1210) may provide a metaverse service to the user terminal (1220). The network may be formed by at least one intermediate node (1230) including an access point (AP) and / or a base station. The user terminal (1220) may connect to the server (1220) through the network and output a user interface (UI) related to the metaverse service to the user of the user terminal (1220). Based on the above UI, the user terminal (1220) can obtain information to be input into the metaverse service from the user, or output information related to the metaverse service (e.g., multimedia content) to the user.

[0122] At this time, the server (1210) provides a virtual space so that the user terminal (1220) can be active in the virtual space. In addition, the user terminal (1220) installs a software agent for accessing the virtual space provided by the server (1210) to express information provided by the server (1210) to the user or transmit information that the user wishes to express in the virtual space to the server. The software agent may be provided directly through the server (1210), downloaded from a public server, or embedded and provided when the terminal is purchased.

[0123] In one embodiment, the metaverse service may be provided to a user terminal (1220) and / or a user using a server (1210). The embodiment is not limited thereto, and the metaverse service may be provided through individual contact between users. For example, within a network environment (1201), the metaverse service may be provided independently from the server (1210) through a direct connection between a first terminal (1220-1) and a second terminal (1220-2). Referring to FIG. 12, within the network environment (1201), the first terminal (1220-1) and the second terminal (1220-2) may be connected to each other through a network formed by at least one intermediate node (1230). In one embodiment where the first terminal (1220-1) and the second terminal (1220-2) are directly connected, either of the user terminals of the first terminal (1220-1) and the second terminal (1220-2) may perform the role of the server (1210). For example, a metaverse environment may be configured solely through device-to-device connections (e.g., peer-to-peer (P2P) connections).

[0124] In one embodiment, the user terminal (1220) (or the user terminal (1220) including the first terminal (1220-1) and the second terminal (1220-2)) may be made in various form factors and is characterized by including an output device for providing images and / or sounds to the user and an input device for inputting information into a metaverse service. Examples of various form factors of the user terminal (1220) include a smartphone (e.g., the second terminal (1220-2)), an AR device (e.g., the first terminal (1220-1)), a VR device, an MR device, a VST (Video See Through) device, an OST (Optical See Through) device, a smart lens, a smart mirror, an input / output capable TV or projector.

[0125] The network (e.g., a network formed by at least one intermediate node (1230)) includes various broadband networks including 3G, 4G, and 5G, and short-range networks including Wifi and BT (e.g., a wired network or wireless network directly connecting the first terminal (1220-1) and the second terminal (1220-2)).

[0126] A method for identifying an emergency state of a wearable device and responding to the emergency state may be required. As described above, a wearable device (101) according to an embodiment may include a communication circuit (240), a display (230), a camera (250), a memory for storing instructions, and a processor (210). The instructions, when executed by the processor, may cause the wearable device to display a screen (110) representing a virtual reality service through the display (230). The instructions, when executed by the processor, may cause the wearable device to receive user's biometric data from an external electronic device (103) through the communication circuit (240) while displaying the screen (110) representing the virtual reality service. The instructions, when executed by the processor, may cause the wearable device, in response to the biometric data indicating an emergency condition of the user, to stop displaying the screen (110) and display an image acquired through the camera (250) together with a first visual object indicating the emergency condition.

[0127] According to one embodiment, the instructions, when executed by the processor, may cause the wearable device to display a second visual object (120) representing parameters included in the biometric data while the level of the emergency condition is below a designated level for suspending display of the screen (110) representing the virtual reality service.

[0128] According to one embodiment, the instructions, when executed by the processor, may cause the wearable device to display the second visual object (120) overlapping the screen (110) representing the virtual reality service.

[0129] According to one embodiment, the wearable device (101) may further include a sensor (260). The instructions, when executed by the processor, may cause the wearable device to identify, using the sensor (260), an amount of light external to the wearable device (101) while displaying the image acquired through the camera. The instructions, when executed by the processor, may cause the wearable device to determine, based on identifying the amount of light exceeding a specified threshold, a location corresponding to the light source within the image acquired through the camera. The instructions, when executed by the processor, may cause the wearable device to display, on the image displayed on the display, a third visual object as an overlay on the determined location to obscure the light source represented by the image.

[0130] According to one embodiment, the instructions, when executed by the processor, may cause the wearable device to receive motion data of the user from the external electronic device (103). The instructions, when executed by the processor, may cause the wearable device to identify the emergency condition in response to the motion data.

[0131] According to one embodiment, the instructions, when executed by the processor, may cause the wearable device to display a fourth visual object including a message for guiding a movement of the user based on a change in the motion data of the user received from the external electronic device being identified as being below a threshold while displaying the screen (110) representing the virtual reality service.
