Although the external appearance of the wearable device (101) having the form of glasses is illustrated, the embodiments are not limited thereto. An example of a hardware configuration included within the wearable device (101) is described exemplarily with reference to FIG. 4. An example of the structure of a wearable device (101) that can be worn on a user's head is described with reference to FIGS. 2a, FIGS. 2b, FIGS. 3a and / or FIGS. 3b.

[0044] According to one embodiment, a wearable device (101) can perform functions related to augmented reality (AR) and / or mixed reality (MR). For example, while a user is wearing the wearable device (101), the wearable device (101) may include at least one lens positioned adjacent to the user's eye. The wearable device (101) may combine light emitted from a display of the wearable device (101) with ambient light passing through the lens. The display area of ​​the display may be formed within the lens through which the ambient light passes. Because the wearable device (101) combines the ambient light and the light emitted from the display, the user can see a mixed image of a real object perceived by the ambient light and a virtual object formed by the light emitted from the display. The aforementioned augmented reality, mixed reality, and / or virtual reality may be referred to as extended reality (XR).

[0045] According to one embodiment, a wearable device (101) can perform functions related to VST (video see-through or visible see-through) and / or virtual reality (VR).

The wearable device (101) may composite a virtual object with an image and / or video output through the display, thereby allowing the user to perceive the virtual object together with a real object perceived by ambient light.

[0046] According to one embodiment, a wearable device (101) can identify or recognize the position or location and / or direction or orientation of the wearable device (101) based on an image (and / or video) obtained or acquired using a camera. The wearable device (101) can obtain information about the external space using one or more cameras and / or one or more sensors. The information may include a geographic location of the external space (e.g., GPS (global positioning system) coordinates) identified by one or more sensors. The information may include an image and / or video of the external space identified by one or more cameras. The wearable device (101) can perform object recognition on the image and / or video to identify external objects contained in the external space from the image and / or video.

[0047] Hereinafter, with reference to FIGS. 2a, FIGS. 2b, FIGS. 3a, FIGS. 3b, and FIGS. 4, an example of a hardware configuration of a wearable device (101) is described.

[0048] FIG. 2a illustrates an example of a perspective view of a wearable device. FIG. 2b illustrates an example of one or more hardware components disposed within the wearable device. According to one embodiment, the wearable device (101) may have the form of glasses that are wearable on a part of a user's body (e.g., head). The wearable device (101) of FIG. 2a and FIG. 2b may be an example of the electronic device (101) of FIG. 1. The wearable device (101) may include a head-mounted display (HMD). For example, the housing of the wearable device (101) may include a flexible material such as rubber and / or silicone that has a shape that adheres to a part of the user's head (e.g., a part of the face covering both eyes). For example, the housing of the wearable device (101) may include one or more straps that can be twined around the user's head, and / or one or more temples that can be attached to the ears of the head.

[0049] Referring to FIG. 2a, a wearable device (101) according to one embodiment may include at least one display (250) and a frame (200) supporting at least one display (250).

At least one display (250) may include a first display (250-1) and / or a second display (250-2) spaced apart from the first display (250-1). For example, the first display (250-1) and the second display (250-2) may be positioned at locations corresponding to the user's left eye and right eye, respectively.

[0052] Referring to FIG. 2b, at least one display (250) may provide visual information transmitted from external light to a user through a lens included in at least one display (250) and other visual information distinct from said visual information. The lens may be formed based on at least one of a Fresnel lens, a pancake lens, or a multi-channel lens. For example, at least one display (250) may include a first surface (231) and a second surface (232) opposite to the first surface (231). A display area may be formed on the second surface (232) of at least one display (250). When a user wears the wearable device (101), external light may 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 by at least one optical device (282, 284) on a real image transmitted through external light in a display area formed on the second surface (232).

[0053] In one embodiment, at least one display (250) may include at least one waveguide (233, 234) that diffracts light emitted from at least one optical device (282, 284) and transmits it to a user. At least one waveguide (233, 234) may be formed based on at least one of glass, plastic, or polymer. A nano pattern may be formed on the exterior or at least a portion of the interior of at least one waveguide (233, 234). The nano pattern may be formed based on a polygonal and / or curved grating structure. Light incident on one end of at least one waveguide (233, 234) may be propagated to the other end of 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., DOE (diffractive optical element), HOE (holographic optical element)) and at least one reflective element (e.g., a reflective mirror). For example, at least one waveguide (233, 234) may be placed within a wearable device (101) to guide a screen displayed by at least one display (250) to the user's eye. For example, the screen may be transmitted to the user's eye based on total internal reflection (TIR) ​​occurring within at least one waveguide (233, 234).

According to one embodiment, a wearable device (101) can identify an external object touching the frame (200) (e.g., a user's fingertip) and / or a gesture performed by said external object by using a touch sensor, a grip sensor, and / or a proximity sensor formed on at least a portion of the surface of the frame (200).

[0058] According to one embodiment, the wearable device (101) may include hardware that performs various functions (e.g., hardware to be described later based on the block diagram of FIG. 4). For example, the hardware 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 PCB (printed circuit board) (290) (e.g., a printed circuit board). The various hardware may be placed within a frame (200).

[0059] According to one embodiment, a microphone (e.g., microphones (265-1, 265-2, 265-3)) of a wearable device (101) is positioned on at least a portion of a frame (200) to acquire a sound signal. A first microphone (265-1) positioned on a bridge (203), a second microphone (265-2) positioned on a second rim (202), and a third microphone (265-3) positioned on a first rim (201) are shown in FIG. 2b, but the number and position of the microphones (265) are not limited to the embodiment of FIG. 2b. If there are two or more microphones (265) included in the wearable device (101), the wearable device (101) can identify the direction of the sound signal by using a plurality of microphones positioned on different portions of the frame (200).

[0060] According to one embodiment, at least one optical device (282, 284) may 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) may be a projector. At least one optical device (282, 284) may be disposed adjacent to at least one display (250) or included within at least one display (250) as part of at least one display (250). According to one embodiment, a wearable device (101) may 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).

[0061] In one embodiment, the camera (260) may include a shooting camera (260-4), an eye tracking camera (ET CAM) (260-1), and / or a motion recognition camera (260-2, 206-3). The shooting camera (260-4), the eye tracking camera (260-1), and the motion recognition camera (260-2, 260-3) may be positioned at different locations on the frame (200) and may perform different functions. The eye tracking camera (260-1) may output data indicating the position of the eyes or the gaze of a user wearing the wearable device (101). For example, the wearable device (101) may detect the gaze from an image containing the user's pupils obtained through the eye tracking camera (260-1). A wearable device (101) can identify an object focused by a user (e.g., a real object, and / or a virtual object) by using the user's gaze obtained through an eye-tracking camera (260-1). The wearable device (101), having identified the focused object, can perform a function for interaction between the user and the focused object (e.g., gaze interaction). The wearable device (101) can represent a portion corresponding to the eyes of an avatar representing the user in a virtual space by using the user's gaze obtained through an eye-tracking camera (260-1). The wearable device (101) 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 area related to the gaze within the image and the visual quality of a second area distinguished from the first area (e.g., resolution, brightness, saturation, grayscale, PPI (pixels per inch)) may differ from each other. In the present disclosure, the term "resolution" is used to refer to the density of pixels of an image and / or display.The density and / or resolution of the pixels may be measured based on units of PPI and / or dpi (dots per inch) or may be parameterized. The wearable device (101) may acquire an image having a visual quality of a first region and a visual quality of a second region that matches the user's gaze by using foveated rendering. For example, if the wearable device (101) supports an iris recognition function, user authentication may be performed based on iris information acquired using an eye-tracking camera (260-1). An example in which the eye-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 eye-tracking camera (260-1) may be positioned solely toward the user's left eye or toward both eyes.

[0062] In one embodiment, the camera (260-4) can capture a real image or background to be matched with a virtual image in order to implement augmented reality or mixed reality content. The camera (260-4) can be used to acquire high-resolution images based on HR (high resolution) or PV (photo video). The camera (260-4) can capture an image of a specific object located at the position 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 regarding a real image or background including the image of the specific object acquired using the camera (260-4) and a virtual image provided through at least one optical device (282, 284) are superimposed. The wearable device (101) can compensate for depth information (e.g., the distance between the wearable device (101) and an external object acquired through a depth sensor) using the image acquired through the camera (260-4). The wearable device (101) can perform object recognition through an image acquired using a shooting camera (260-4). The wearable device (101) 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 shooting camera (260-4). The wearable device (101) can perform a pass-through function to superimpose an image acquired through the shooting camera (260-4) onto at least a portion of a screen representing a virtual space while displaying the screen representing a virtual space on at least one display (250). In one embodiment, the shooting camera (260-4) may be placed on a bridge (203) positioned between a first rim (201) and a second rim (202).

[0063] The eye tracking camera (260-1) can achieve more realistic augmented reality by tracking the gaze of a user wearing the wearable device (101), thereby matching the user's gaze with visual information provided to at least one display (250). For example, when the user looks straight ahead, the wearable device (101) can naturally display environmental information related to the user's front on at least one display (250) at the location where the user is situated. The eye tracking camera (260-1) may be configured to capture an image of the user's pupil to determine the user's gaze. For example, the eye tracking camera (260-1) may receive a 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 eye tracking camera (260-1) may be positioned at locations corresponding to the user's left and right eyes. For example, the eye-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 (101) is located.

[0064] The motion recognition camera (260-2, 260-3) can provide a specific event to a screen provided on at least one display (250) by recognizing the movement of the user's entire body or part thereof, such as the user's torso, hands, or face. The motion recognition camera (260-2, 260-3) can recognize the user's gesture, acquire a signal corresponding to the gesture, and provide a display corresponding to the signal to at least one display (250). The processor can identify the signal corresponding to the gesture and, based on the identification, perform a designated function. The motion recognition camera (260-2, 260-3) can be used to perform spatial recognition functions using SLAM and / or depth maps for a 6-degrees-of-freedom pose (6 dof pose). The processor can use the motion recognition camera (260-2, 260-3) to perform gesture recognition functions and / or object tracking functions. In one embodiment, a motion recognition camera (260-2, 260-3) may be placed on the first rim (201) and / or the second rim (202).

[0065] The camera (260) included in the wearable device (101) is not limited to the eye-tracking camera (260-1) and motion recognition camera (260-2, 260-3) described above. For example, the wearable device (101) can identify external objects included within the FoV by using a camera positioned toward the user's FoV. The identification of external objects by the wearable device (101) can be performed based on a sensor for identifying the distance between the wearable device (101) and the external object, such as a depth sensor and / or a time of flight (ToF) sensor. The camera (260) positioned toward the FoV may support an autofocus function and / or an optical image stabilization (OIS) function.

[0094] Referring to FIG. 5, the power input circuit (401) may have an input voltage applied through a first port (511). For example, the first port (511) may include a Type-C port. The first port (511) may be connected to a first overvoltage protection circuit (OVP) (513). The first overvoltage protection circuit (513) may be configured to detect overvoltage. When the first overvoltage protection circuit (513) detects overvoltage, it may protect the electronic device (101) by cutting off the voltage supply.

[0095] According to one embodiment, the first overvoltage protection circuit (513) can provide an input voltage to the first power delivery circuit (PD) (515). For example, the first power delivery circuit (515) may be configured to control the first load switch (517).

The electronic device (101) can identify whether an input voltage is applied using the first port (511) through the state of the CTRL pin. For example, if an input voltage is applied through the first port (511), the state of the CTRL pin may be indicated as a high state. For example, if an input voltage is not applied through the first port (511), the state of the CTRL pin may be indicated as a low state.

When the second overvoltage protection circuit (523) detects overvoltage, it may protect the electronic device (101) by cutting off the voltage supply.

[0100] According to one embodiment, the second overvoltage protection circuit (523) can provide an input voltage to the second power delivery circuit (PD) (525). For example, the second power delivery circuit (525) may be configured to control the second load switch (527).

The electronic device (101) can identify whether an input voltage is applied through the second port (521) through the state of the CTRL pin. For example, if an input voltage is applied through the second port (521), the state of the CTRL pin may be indicated as high. For example, if an input voltage is not applied through the second port (521), the state of the CTRL pin may be indicated as low. For example, at least one processor (400) can identify that the provision of the input voltage is interrupted as the state of the CTRL pin of the second power delivery circuit (525) changes from high to low.

[0102] According to one embodiment, the second load switch (527) may be provided with an input voltage applied through the second port (521). The second load switch (527) may be configured to selectively provide or not provide the input voltage to the regulator (403) under the control of the second power transfer circuit (525).

[0105] According to one embodiment, when an input voltage is applied through the power input circuit (401), the input voltage may be provided to the system input terminal (530). For example, while the input voltage is provided to the system input terminal (530), the battery (409) may be electrically connected to the system input terminal (530). For example, while the input voltage is provided to the system input terminal (530), the battery (409) may be charged. When the provision of the input voltage to the system input terminal (530) is interrupted, the battery (409) may provide battery voltage to the system input terminal (530). For example, while the battery (409) provides battery voltage to the system input terminal (530), the electronic device (101) may operate in sleep mode.

[0106] According to one embodiment, when a specified time has elapsed since the point at which the supply of input voltage to the system input terminal (530) is discontinued, the electronic device (101) may provide a factory mode. When a specified time has elapsed since the point at which the supply of input voltage to the system input terminal (530) is discontinued, the control circuit (407) may control the switch (541) to disconnect the system input terminal (530) and the battery (409).

For example, the specified time may be set by a user. The specified time may be greater than the minimum operating time for turning off the system.

[0107] According to one embodiment, the control circuit (407) can detect that an input voltage is provided to the system input terminal after the system input terminal (530) and the battery (409) are disconnected. In response to detecting that an input voltage is provided to the system input terminal, the control circuit (407) can control the switch (541) to connect the battery (409) and the system input terminal (530).

For example, the battery voltage of the battery (409) may be approximately 4.14 V. In section (671), the control circuit (407) may control the switching circuit (405) to connect the battery (409) and the system input terminal (530). While the battery (409) and the system input terminal (530) are connected, the control circuit (407) may provide a voltage to the switching circuit (405) to control the switching circuit (405). For example, the voltage to control the switching circuit (405) by the control circuit (407) may be approximately 1.76 V.

At time point (650), the state of the CTRL pin of the second power delivery circuit (525) may change from high to low. When reference to line (620) at time point (650), the provision of an input voltage to the system input terminal (530) may stop. At time point (650), the control circuit (407) may execute a sequence (e.g., a power off sequence) to disconnect the battery (409) and the system input terminal (530).

[0113] According to one embodiment, in section (673), the battery voltage of the battery (409) may be provided to the system input terminal (530). In section (673), the line (620) and the line (630) may overlap. Section (673) may include a minimum operating time required for the system to shut down as the provision of the input voltage is discontinued. As an example, but not limited to, the length of section (673) may be changed according to the user's settings. For example, in section (673), the electronic device (101) may provide a sleep mode. For example, in section (673), the electronic device (101) may utilize a hot-swap function.

[0114] According to one embodiment, in section (675), an operation to disconnect the battery (409) and the system input terminal (530) may be performed. For example, in section (675), the electronic device (101) may be changed from sleep mode to factory mode.

[0115] According to one embodiment, when referring to line (640) at time point (660), the voltage for the control circuit (407) to control the switching circuit (405) can be changed to about 0 V.

[0116] According to one embodiment, in section (677), the voltage of the system input terminal (530) may be about 0 V because the battery (409) and the system input terminal (530) are disconnected. In section (677), the battery voltage of the battery (409) may be maintained because the battery (409) and the system input terminal (530) are disconnected. For example, the battery voltage may be maintained at about 4.14 V.

[0117] FIG. 7 illustrates an example of the battery voltage of a battery (e.g., battery (409)) disconnected from a system input terminal (e.g., system input terminal (530)).

[0118] Referring to FIG. 7, the graph (700) may represent the state of the battery voltage of the battery (409) disconnected from the system input terminal (530) over time. The horizontal axis of the graph (700) may represent time. The unit of the graph (700) may be days. The vertical axis of the graph (700) may represent the magnitude of the battery voltage of the battery (409). The unit of the vertical axis of the graph (700) may be V (volt). The line (710) may represent the battery voltage of the battery (409). For example, the graph (700) may represent the battery voltage of the battery (409) while the electronic device (101) is in ship mode.

[0119] According to one embodiment, the battery voltage of the battery (409) at the time when the system input terminal (530) and the battery (409) are disconnected may be approximately 4.1422 V. One week after the time when the system input terminal (530) and the battery (409) are disconnected, the battery voltage of the battery (409) may be approximately 4.1392 V.

[0120] According to one embodiment, when the electronic device (101) is not in use, the remaining amount of the battery (409) can be preserved for a relatively long period by providing a shipping mode.

[0121] According to one embodiment, the electronic device (101) can minimize power consumption of the battery (409) while providing a shipping mode. By providing a shipping mode, the electronic device (101) can prevent swelling of the battery (409). Swelling can be described as a phenomenon in which the exterior of the battery (409) bulges out. The probability of swelling occurring may be higher the longer the battery (409) maintains a low voltage state.

[0122] According to one embodiment, by providing a shipping mode for the electronic device (101), the idle period of the electronic device (101) (e.g., about 145 months) can be increased by the shelf life of the electronic device (101) (e.g., about 145 months). The idle period may be referenced as the time elapsed from when the user opened the electronic device (101) after purchasing it until the battery (409) is discharged by leakage current. The shelf life may be referenced as the time elapsed before the electronic device (101) is opened by the user until the battery (409) is discharged by leakage current.

[0124] Referring to FIG. 8, in operation 801, an electronic device (101) (e.g., at least one processor (400)) can identify that the supply of input voltage to a power input circuit (e.g., power input circuit (401)) (or system input terminal (530)) is interrupted. For example, the electronic device (101) can identify that the state of the CTRL pin of a power delivery circuit (e.g., first power delivery circuit (515), second power delivery circuit (525)) changes from a high state to a low state. The electronic device (101) can identify that the supply of input voltage to a system input terminal (e.g., system input terminal (530)) is interrupted.

[0125] According to one embodiment, the electronic device (101) may display a visual object through the display of the electronic device (101) based on identifying that the supply of input voltage to the power input circuit (401) (or system input terminal (530)) has been interrupted. For example, the visual object may indicate that the supply of input power has been interrupted. For example, the visual object may include a message to supply input power.

[0126] According to one embodiment, the electronic device (101) may provide the battery voltage of a battery (e.g., battery (409)) to the system input terminal (530) for a specified time based on identifying when the supply of input voltage to the power input circuit (401) (or system input terminal (530)) is interrupted. For example, the electronic device (101) may provide a sleep mode for a specified time. For example, the electronic device (101) may utilize a hot-swap function. For example, the specified time may be set by a user.

[0127] In operation 803, the electronic device (101) (e.g., at least one processor (400)) can identify whether an input voltage is provided to the power input circuit (401) (or system input terminal (530)) before the specified time elapses. For example, the electronic device (101) can identify whether an input voltage is provided to the system input terminal (530) before the specified time elapses. For example, the electronic device (101) can identify whether the state of the CTRL pin of the power delivery circuit (e.g., first power delivery circuit (515), second power delivery circuit (525)) changes from a low state to a high state before the specified time elapses. Based on identifying that an input voltage is provided before the specified time elapses, the electronic device (101) can execute operation 805. The electronic device (101) can execute operation 807 based on identifying that the input voltage is not provided to the power input circuit (401) (or system input terminal (530)) before the specified time has elapsed.

[0128] In operation 805, the electronic device (101) (e.g., at least one processor (400)) may control the control circuit (407) so that the switching circuit (e.g., switching circuit (405)) maintains the connection between the battery (409) and the system input terminal (530) based on identifying that the input voltage is provided before the specified time has elapsed. If the input voltage is provided before the specified time has elapsed, the electronic device (101) may maintain the state prior to the cessation of the input voltage provision in operation 805. The user may use the electronic device (101) in the state prior to the cessation of the input voltage provision in operation 805.

[0129] In operation 803, the electronic device (101) (e.g., at least one processor (400)) may, based on identifying that no input voltage is provided before the specified time has elapsed, control the control circuit (407) in operation 807 so that the switching circuit (405) disconnects the connection between the battery (409) and the system input terminal (530). If no input voltage is provided before the specified time has elapsed, the electronic device (101) may operate in factory mode.

[0130] According to one embodiment, the electronic device (101) can detect, using a control circuit (407), that an input voltage is provided to the system input terminal (530) while the connection between the battery (409) and the system input terminal (530) is disconnected. In response to the detection, the electronic device (101) can control the connection between the battery (409) and the system input terminal (530) using the control circuit (407). In response to the detection, the electronic device (101) can release the factory mode.

[0131] In an embodiment according to the present disclosure, an electronic device (e.g., electronic device (101)) may be provided with an input voltage from an external electronic device (e.g., external input device). As the provision of the input voltage is interrupted, the electronic device (101) may use a control circuit (e.g., control circuit (407)) to control a switching circuit (e.g., switching circuit (405)) to disconnect a battery (e.g., battery (409)) from a system input terminal (e.g., system input terminal (530)). By disconnecting the battery (409) from the system input terminal (530), the leakage current of the battery (409) may be reduced. As the leakage current of the battery (409) is reduced, the usage period (or idle period) of the electronic device (101) may be increased. Additionally, as the leakage current of the battery (409) is reduced, swelling may be prevented.
