[0041] 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).

[0042] 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.

According to 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.

[0045] 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)).

[0046] 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.

As shown in FIG. 2A, the wearable device (200), according to an embodiment, may include at least one display (250) and a frame supporting the at least one display (250).

[0048] According to one embodiment, a wearable device (200) may be worn on a part of a user's body. The wearable device (200) may provide augmented reality (AR), virtual reality (VR), or mixed reality (MR) that combines augmented reality and virtual reality to a user wearing the wearable device (200). For example, the wearable device (200) may output a virtual reality image to the user through at least one display (250) in response to a user's designated gesture acquired through the motion recognition cameras (240-2, 240-5) of FIG. 2B.

[0049] According to one embodiment, at least one display (250) within a wearable device (200) may provide visual information to a user. For example, at least one display (250) may include a transparent or translucent lens. 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 positions corresponding to the user's left and right eyes, respectively.

[0050] Referring to FIG. 2B, at least one display (250) may form a display area on a lens to provide a user wearing the wearable device (200) with visual information contained in external light passing through the lens, along with other visual information distinct from the visual information. The lens may be formed based on at least one of a Fresnel lens, a pancake lens, or a multi-channel lens. The display area formed by at least one display (250) may be formed on the second surface (232) among the first surface (231) and the second surface (232) of the lens. When the user wears the wearable device (200), external light may be incident on the first surface (231) and transmitted through the second surface (232) to be transmitted to the user. As another example, at least one display (250) 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 (250) can be transmitted to the user's eyes through one or more hardware (e.g., optical devices (282, 284), and / or at least one waveguide (233, 234)) included in the wearable device (200).

[0051] According to one embodiment, a wearable device (200) may include waveguides (233, 234) that diffract light transmitted from at least one display (250) and relayed by optical devices (282, 284) and transmit the diffracted light to a user. The waveguides (233, 234) may be formed based on at least one of glass, plastic, or polymer. A nanopattern may be formed on at least a portion of the exterior or interior of the waveguides (233, 234). The nanopattern may be formed based on a grating structure having a polygonal and / or curved shape. Light incident on one end of the waveguides (233, 234) may be propagated to the other end of the waveguides (233, 234) by the nanopattern. The wave guides (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, the wave guides (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 wave guides (233, 234).

[0052] According to one embodiment, the wearable device (200) may analyze an object included in a real image collected through a capturing camera (240-3, 240-6), combine a virtual object corresponding to an object to be provided with augmented reality among the analyzed objects, and display the virtual object on at least one display (250). The virtual object may include at least one of text and an image regarding various information related to the object included in the real image.

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

[0053] According to one embodiment, the frame 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 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 may support at least one display (250). For example, the frame 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.

[0054] Referring to FIG. 2A, the frame 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 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 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 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.

[0055] For example, the frame 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.

According to one embodiment, a wearable device (300) may include cameras (340-3, 340-4) for photographing and / or recognizing a face of a user. The cameras (340-3, 340-4) may be referred to as FT cameras.

[0074] Referring to FIG. 3B, a camera (e.g., cameras (340-5, 340-6, 340-7, 340-8, 340-9, 340-10)) and / or a sensor (e.g., depth sensor (330)) for obtaining information related to the external environment of the wearable device (300) may be disposed on a second surface (320) opposite to the first surface (310) of FIG. 3A. For example, the cameras (340-5, 340-6, 340-7, 340-8, 340-9, 340-10) may be disposed on the second surface (320) to recognize an external object different from the wearable device (300). For example, using cameras (340-9, 340-10), the wearable device (300) can obtain images and / or videos to be transmitted to each of the user's eyes. The camera (340-9) can be placed on the second face (320) of the wearable device (300) to obtain an image to be displayed through the second display (350-2) corresponding to the right eye among the two eyes.

[0082] Below, an operation of performing user authentication in an environment visible to the user (or, the user's field of view (FOV)) by an electronic device (401) is described.

[0083] FIG. 5 illustrates an example of an environment visible to a user, according to one embodiment.

[0084] FIG. 5 may be described with reference to FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, and FIG. 4. Hereinafter, the first camera (481) may be a camera that captures an environment (or, the user's field of view (FOV)) shown to the user (510), the second camera (485) may be a camera for iris recognition, and the third camera (489) may be a gaze tracking camera.

[0085] FIG. 5 illustrates an environment (501) (or, the user's field of view (FOV)) shown to a user (510) while the user (510) is wearing an electronic device (401).

[0086] In one embodiment, the processor (120) of the electronic device (401) can provide a user (510) with augmented reality (AR), virtual reality (VR), or mixed reality (MR) that combines augmented reality and virtual reality.

[0087] In one embodiment, augmented reality (AR) may be an environment in which at least one image object is displayed (or superimposed) on an external environment that is shown to a user (510) through (or through) a display (460, 250, 250-1, 250-2, 350-1, 350-2). For example, the augmented reality (AR) may be a see-through environment. For example, augmented reality (AR) may include a method in which external light passes through the display (460, 250, 250-1, 250-2, 350-1, 350-2) to directly reach the user (510), and / or an image representing an external environment captured by the first camera (481) is displayed through the display (460, 250, 250-1, 250-2, 350-1, 350-2), thereby being displayed to the user (510). However, the present invention is not limited thereto. For example, an image representing an external environment captured by the first camera (481) may be an image having binocular parallax. For example, an image representing an external environment captured by the first camera (481) may be a stereoscopic image.

[0088] Virtual reality (VR) may be an environment in which a virtual environment that is distinct from (or does not reflect) the external environment rendered through a processor (120) is shown to a user (510) through a display (460, 250, 250-1, 250-2, 350-1, 350-2).

[0089] Hereinafter, the environment (501) of FIG. 5 may be exemplified as augmented reality. However, it is not limited thereto. For example, the environment (501) of FIG. 5 may be virtual reality, or mixed reality combining augmented reality and virtual reality.

[0090] In one embodiment, the processor (120) can identify and / or track the gaze (521) of the user (510). For example, the processor (120) can identify the gaze (521) of the user (510) based on images captured by the third camera (489) for eye tracking (ET). For example, the images captured by the third camera (489) may be glint images. For example, the processor (120) can identify the gaze (521) of the user (510) based on the position of the eye included in the images captured by the third camera (489). For example, the processor (120) can identify the gaze (521) of the user (510) based on the position of the iris included in the images captured by the third camera (489). For example, the processor (120) can identify the gaze (521) of the user (510) by tracking the position of the iris. However, the present invention is not limited thereto.

[0091] In one embodiment, the processor (120) may obtain an authentication request from the user (510). For example, the processor (120) may obtain an authentication request based on iris recognition. For example, the processor (120) may obtain the authentication request while the environment (501) is provided to the user (510). For example, the processor (120) may obtain an authentication request based on iris recognition generated by the program (140) while the program (140) is executing.

[0092] In one embodiment, the processor (120) may determine whether user authentication based on iris recognition is possible in response to an authentication request from the user (510). In one embodiment, the processor (120) may determine whether iris recognition is possible in response to an authentication request based on the iris of the user (510).

[0093] In one embodiment, the processor (120) may determine whether user authentication based on iris recognition is possible based on the size of the iris of the user's (510) eye. For example, the processor (120) may identify the size of the iris based on an image of the user's (510) eye acquired through the second camera (485). The processor (120) may determine whether iris recognition is possible based on the size of the iris identified based on the image of the eye. For example, if the size of the iris exceeds a first specified size, iris recognition may be determined to be possible. For example, if the size of the iris is less than or equal to the first specified size, iris recognition may be determined to not be possible. The processor (120) may determine whether iris recognition is possible based on a second size of the pupil identified based on the image of the eye. For example, if the second pupil size is less than or equal to a specified second size, iris recognition may be determined to be possible. For example, if the second pupil size exceeds a specified second size, iris recognition may be determined to be impossible. For example, the specified first size and / or the specified second size may be preset.

[0094] In one embodiment, if it is determined that user authentication based on iris recognition is possible, the processor (120) may authenticate the user based on iris recognition using an image acquired through the second camera (485). In one embodiment, if the size of the iris exceeds a specified first size, the processor (120) may authenticate the user based on iris recognition using an image for iris recognition. In one embodiment, if iris recognition using an image for iris recognition fails, the processor (120) may perform an operation to increase the size of the iris of the user's (510) eye.

[0143] In one embodiment, the processor (120) may select (and / or identify) at least one object from among one or more objects that may be brightly represented within the environment (603). In one embodiment, the processor (120) may display an image object (621) that guides the movement of the user's (510) gaze (521) based on the at least one selected object. For example, the processor (120) may select at least one object among a window, a light, or an indirect light, and display an image object (621) that guides the movement of the user's (510) gaze (521) to the selected object.

[0144] In one embodiment, the processor (120) may display an image object (621) that guides the movement of the user's (510) gaze (521) to at least one object adjacent to the user's (510) gaze (521) among one or more objects that can be brightly expressed within the environment (603). Here, at least one object being adjacent to the gaze (521) may mean that at least one object is located within a specified distance from the gaze (521). However, the present invention is not limited thereto. For example, the processor (120) may display an image object (621) that guides the movement of the user's (510) gaze (521) to at least one object outside the specified distance from the user's (510) gaze (521) among one or more objects that can be brightly expressed within the environment (603).

[0145] In one embodiment, the processor (120) can identify and / or track the gaze (521) of the user (510). For example, the processor (120) can identify the gaze (521) of the user (510) based on images acquired by the third camera (489). In one embodiment, the processor (120) can identify and / or track the gaze (521) of the user (510) after displaying an image object (621). In one embodiment, the processor (120) can identify that the gaze (521) has moved to at least one object that can be brightly expressed. In one embodiment, the processor (120) can identify that the gaze (521) has moved in a direction (and / or location) indicated by the image object (621).

[0146] In one embodiment, the processor (120) may adjust (e.g., increase) the brightness of the selected area (613). In one embodiment, if it is determined that user authentication based on iris recognition is not possible, the processor (120) may adjust (e.g., increase) the brightness of the selected area (613). By adjusting (e.g., increasing) the brightness of the area (613) within the environment (604), the size of the iris of the user's (510) eye may increase. Here, adjusting (e.g., increasing) the brightness may mean adjusting the transparency of a transparent or translucent lens included in at least one display (250) within the wearable device (200) of FIG. 2A and / or FIG. 2B to be transparent. For example, adjusting (e.g., increasing) brightness may mean increasing the brightness of an area displayed through at least one display (250) in the wearable device (200) of FIG. 2A and / or FIG. 2B. For example, adjusting (e.g., increasing) brightness may mean increasing the brightness of an area displayed through at least one display (350-1, 350-2) in the wearable device (300) of FIG. 3A and / or FIG. 3B. For example, adjusting (e.g., increasing) brightness may mean superimposing a transparent and / or translucent layer on an image displayed through at least one display (350-1, 350-2) to provide augmented reality (AR), virtual reality (VR), or mixed reality (MR). Here, the transparent and / or translucent layer may have a brightness higher than a specified brightness in a selected area of ​​the image. The layer may be transparent in an area other than the selected area of ​​the image. A layer can have a selected area in the image that has a brightness greater than the specified brightness.

[0147] In one embodiment, the processor (120) can obtain an image of the eye through the second camera (485). In one embodiment, the processor (120) can obtain an image for iris recognition through the second camera (485).

[0148] In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of the environment (604) is adjusted. In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of an area (613) within the environment (604) is adjusted. In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of an area (613) of a user (510) within the environment (604) is adjusted.

[0149] In one embodiment, the processor (120) may authenticate a user (510) based on an iris included in an image for iris recognition. In one embodiment, the processor (120) may authenticate a user (510) based on an iris included in an image for iris recognition acquired while the brightness of an area (613) is adjusted.

[0150] As described above, when adjusting brightness for iris recognition, the electronic device (401) can reduce discomfort (e.g., glare) to the user (510) by optimizing the intensity of light for iris recognition. When adjusting brightness for iris recognition, the electronic device (401) can guide the user's (510) gaze (521) to an object that can be expressed brightly in the environment (604), thereby relatively reducing the intensity of light in the area (613) where the gaze (521) is located.

[0151] Below, the operation of guiding the user's movement to an area that can be brightly expressed in the previous field of view (or environment) by the electronic device (401) is described.

[0152] FIG. 6d illustrates an example of an environment visible to a user, according to one embodiment.

[0153] FIG. 6d can be described with reference to FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 4, and FIG. 5. Hereinafter, the first camera (481) may be a camera that captures an environment (or, the user's field of view (FOV)) shown to the user (510), the second camera (485) may be a camera for iris recognition, and the third camera (489) may be a gaze tracking camera.

[0154] FIG. 6d illustrates environments (605, 606) (or, the user's fields of view) visible to the user (510) while the user (510) is wearing the electronic device (401). The environments (605, 606) of FIG. 6d may be visible to the user (510) after the environment (501) of FIG. 5 is visible to the user (510). The environment (606) of FIG. 6d may be visible to the user (510) after the environment (605) of FIG. 6d is visible to the user (510). Hereinafter, the environment visible to the user (or, the user's fields of view) may be referred to as an environment.

[0155] In one embodiment, the processor (120) may perform an operation to increase the size of the iris of the user's (510) eye. In one embodiment, the processor (120) may perform an operation to increase the size of the iris of the user's (510) eye when the brightness of the area where the user's (510) gaze (521) is located is insufficient and user authentication based on iris recognition fails.

[0156] In one embodiment, the processor (120) can analyze the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605). In one embodiment, the analysis of the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) can be performed in the background. In one embodiment, the processor (120) can be continuously performing the analysis of the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605). For example, analyzing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) can mean identifying one or more objects in an image representing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) acquired through the first camera (481). For example, analyzing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) may mean, but is not limited to, identifying one or more objects in an image representing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) obtained through the first camera (481) while augmented reality (AR) and / or mixed reality (MR) is provided to the user (510). For example, analyzing an environment (605) and / or an environment (606) provided to a user (510) prior to the environment (605) may mean identifying one or more objects in an image representing the environment (605) displayed via a display (460, 250, 250-1, 250-2, 350-1, 350-2) and / or the environment (606) provided to a user (510) prior to the environment (605).For example, analyzing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) may mean identifying one or more objects in an image representing the environment (605) and / or the environment (606) provided to the user (510) prior to the environment (605) displayed via a display (460, 250, 250-1, 250-2, 350-1, 350-2) while virtual reality (VR) and / or mixed reality (MR) is provided to the user (510). For example, the environment (606) may be different from the environment (605). For example, the environment (606) being different from the environment (605) may mean that a space (e.g., a kitchen) of the environment (606) is different from a space (e.g., a living room) of the environment (605). For example, the fact that the environment (606) is different from the environment (605) may mean that the user's (510) field of view is different in the same space (e.g., living room). For example, the environment (606) may be an environment provided to the user (510) when looking in a first direction in the same space (e.g., living room), and the environment (605) may be an environment provided to the user (510) when looking in a second direction different from the first direction in the same space (e.g., living room). However, the present invention is not limited thereto.

[0157] In one embodiment, the processor (120) may determine whether an object that can be expressed brightly exists within the environment (605) based on analyzing the environment (605). In one embodiment, if it is determined that user authentication based on iris recognition is not possible, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605). In one embodiment, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605) in order to perform an operation to increase the size of the iris of the user's (510) eye. In one embodiment, if iris recognition using an image for iris recognition fails, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605). In one embodiment, the processor (120) can determine whether there is an object that can be brightly expressed within the analyzed environment (605) if iris recognition using an image for iris recognition fails before performing an operation to increase the size of the iris of the user's (510) eye.

In one embodiment, the processor (120) can determine whether there is an object that can be brightly expressed within the analyzed environment (606) if iris recognition using an image for iris recognition fails before performing an action to increase the size of the iris of the user's (510) eye.

[0159] In one embodiment, the processor (120) may display an image object (622) that guides the movement of the user (510). In one embodiment, the processor (120) may display the image object (622) based on analyzing the environment (605) and / or the environment (606).

For example, the processor (120) may display the image object (622) that guides the movement of the user (510) from the environment (605) to the environment (606).

[0160] Referring to FIG. 6d, the processor (120) may display an image object (622) pointing to a door that can move to the environment (606), but is not limited thereto.

In one embodiment, the processor (120) may display an image object (622) that guides the movement of the user (510) based on the selected environment (606).

[0162] In one embodiment, the processor (120) may display an image object (622) that guides movement of the user (510) to an environment (606) adjacent to the user (510) among one or more previous environments movable within the environment (605). Here, the environment (606) being adjacent to the user (510) may mean that the environment (606) is located within a specified distance from the user (510).

[0163] In one embodiment, the processor (120) may identify and / or track the movement of the user (510) and / or the movement of the gaze (521).

[0164] For example, the processor (120) can identify the movement of the user (510) through a sensor (e.g., the sensor module (176) of FIG. 1). For example, the processor (120) can identify the movement of the user (510) through an inertial sensor. For example, the processor (120) can identify the movement of the user (510) and / or the movement of the gaze (521) based on images acquired by the third camera (489). In one embodiment, the processor (120) can identify and / or track the movement of the user (510) and / or the movement of the gaze (521) after displaying an image object (622). In one embodiment, the processor (120) can identify that the user (510) is moving into the environment (606). In one embodiment, the processor (120) may identify that the user (510) has moved into an environment (606) indicated by an image object (622).

[0165] In one embodiment, the processor (120) can adjust (e.g., increase) the brightness of at least one selected region (615, 616). In one embodiment, the processor (120) can adjust (e.g., increase) the brightness of at least one selected region (615, 616) in response to the user (510) moving into an environment (606) indicated by the image object (622). By adjusting (e.g., increasing) the brightness of at least one region (615, 616) within the environment (606), the size of the iris of the user's (510) eye can be increased. Here, adjusting (e.g., increasing) the brightness can mean adjusting the transparency of a transparent or translucent lens included in at least one display (250) within the wearable device (200) of FIG. 2A and / or FIG. 2B to be transparent. For example, adjusting (e.g., increasing) brightness may mean increasing the brightness of an area displayed through at least one display (250) in the wearable device (200) of FIG. 2A and / or FIG. 2B. For example, adjusting (e.g., increasing) brightness may mean increasing the brightness of an area displayed through at least one display (350-1, 350-2) in the wearable device (300) of FIG. 3A and / or FIG. 3B. For example, adjusting (e.g., increasing) brightness may mean superimposing a transparent and / or translucent layer on an image displayed through at least one display (350-1, 350-2) to provide augmented reality (AR), virtual reality (VR), or mixed reality (MR). Here, the transparent and / or translucent layer may have a brightness higher than a specified brightness in a selected area of ​​the image. The layer may be transparent in an area other than the selected area of ​​the image. A layer can have a selected area in the image that has a brightness greater than the specified brightness.

[0166] In one embodiment, the processor (120) can obtain an image of the eye through the second camera (485). In one embodiment, the processor (120) can obtain an image for iris recognition through the second camera (485).

[0167] In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of the environment (606) is adjusted. In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of at least one area (615, 616) within the environment (606) is adjusted. In one embodiment, the processor (120) can acquire an image for iris recognition while the brightness of at least one area (615, 616) of the user (510) within the environment (606) is adjusted.

In one embodiment, the processor (120) may authenticate a user (510) based on an iris included in an image for iris recognition acquired while the brightness of at least one area (615, 616) is adjusted.

[0169] As described above, when adjusting brightness for iris recognition, the electronic device (401) can reduce discomfort (e.g., glare) to the user (510) by optimizing the intensity of light for iris recognition. When adjusting brightness for iris recognition, the electronic device (401) can relatively slightly increase the brightness of the environment provided to the user (510) by guiding the user (510) to an environment (606) in which objects that can be expressed brightly exist.

[0170] In FIG. 6d, the electronic device (401) is illustrated as guiding the user's movement to an area that can be brightly expressed in the previous field of view (or environment), but this is merely an example. In some embodiments, the electronic device (401) may also guide the user's movement of the field of view within the same space without requiring the user to move spatially.

[0171] In one embodiment, the processor (120) may analyze the environment (605). In one embodiment, the analysis of the environment (605) may be performed in the background. In one embodiment, the processor (120) may be continuously performing the analysis of the environment (605). For example, analyzing the environment (605) may mean identifying one or more objects in an image representing the environment (605) acquired through the first camera (481). For example, analyzing the environment (605) may mean identifying one or more objects in an image representing the environment (605) acquired through the first camera (481) while augmented reality (AR) and / or mixed reality (MR) is provided to the user (510). However, the present invention is not limited thereto. For example, analyzing an environment (605) may mean identifying one or more objects in an image representing the environment (605) displayed via a display (460, 250, 250-1, 250-2, 350-1, 350-2). For example:

In one embodiment, if it is determined that user authentication based on iris recognition is not possible, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605). In one embodiment, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605) in order to perform an operation to increase the size of the iris of the user's (510) eye. In one embodiment, if iris recognition using an image for iris recognition fails, the processor (120) may determine whether an object that can be expressed brightly exists within the analyzed environment (605). In one embodiment, the processor (120) can determine whether there is an object that can be brightly expressed within the analyzed environment (605) if iris recognition using an image for iris recognition fails before performing an operation to increase the size of the iris of the user's (510) eye.

[0173] In one embodiment, the processor (120) may analyze another environment provided to the user (510) within the same space as the environment (605). In one embodiment, the processor (120) may analyze the another environment to perform an operation to increase the size of the iris of the user's (510) eye. Here, the environment (605) and the other environment may be an environment that may be provided to the user (510) according to a change in the field of view (FOV) of the user (510) with respect to the environment (605) (or, rotation of the field of view). For example, the environment (605) and the other environment may be an environment that may be provided to the user (510) when the position of the face when looking at the environment (605) is rotated to the right or left. The environment (605) and the other environment may mean that the field of view of the user (510) is different from each other in the same space (e.g., a living room). For example, an environment (605) and another environment may be an environment provided to a user (510) when looking in a first direction in the same space (e.g., a living room), and an environment (605) and another environment may be an environment provided to a user (510) when looking in a second direction different from the first direction in the same space (e.g., a living room). However, this is not limited thereto.

[0176] In one embodiment, the processor (120) may select (and / or identify) one other environment from among one or more other environments that are movable within the environment. In one embodiment, the processor (120) may display an image object that guides the movement of the user's (510) field of view based on the selected other environment.

[0177] In one embodiment, the processor (120) may identify and / or track movement of the user's (510) field of view.

[0178] For example, the processor (120) can identify movement of the user's (510) field of view through a sensor (e.g., the sensor module (176) of FIG. 1). For example, the processor (120) can identify movement of the user's (510) field of view through an inertial sensor. For example, the processor (120) can identify movement of the user's (510) field of view based on images acquired by the third camera (489).

[0179] In one embodiment, the processor (120) may adjust (e.g., increase) the brightness of at least one area selected in another environment where the user's (510) field of view has shifted.

The environment (607) of FIG. 6e may be visible to the user (510) after the environment (501) of FIG. 5 is visible to the user (510). Hereinafter, the environment visible to the user (or, the user's field of view) may be referred to as an environment.

[0185] In one embodiment, the processor (120) may perform an operation to increase the size of the iris of the user's (510) eye. In one embodiment, the processor (120) may perform an operation to increase the size of the iris of the user's (510) eye when the brightness of the area where the user's (510) gaze (521) is located is insufficient and user authentication based on iris recognition fails.

[0186] In one embodiment, the processor (120) may analyze the environment (607). In one embodiment, the analysis of the environment (607) may be performed in the background. In one embodiment, the processor (120) may be continuously performing the analysis of the environment (607). For example, analyzing the environment (607) may mean identifying one or more objects in an image representing the environment (607) displayed through a display (460, 250, 250-1, 250-2, 350-1, 350-2). For example, analyzing an environment (607) may mean identifying one or more objects in an image representing the environment (607) displayed via a display (460, 250, 250-1, 250-2, 350-1, 350-2) while virtual reality (VR) and / or mixed reality (MR) is provided to a user (510).

In one embodiment, the processor (120) may select at least one area (623, 624) within the environment (607) when iris recognition using an image for iris recognition fails. In one embodiment, the processor (120) may select at least one area (623, 624) within the environment (607) if iris recognition using an image for iris recognition fails prior to performing an operation to increase the size of the iris of the eye of the user (510).

[0188] In one embodiment, the processor (120) can select at least one area (623, 624) of at least one object within the environment (607) on which visual objects can overlap. In one embodiment, the processor (120) can identify at least one area (623, 624) of at least one object. For example, the at least one object on which visual objects can overlap may include furniture (e.g., sofa, table, bed), appliances (e.g., TV, washing machine, refrigerator), structures (e.g., walls, pillars, ceilings, floors), and / or other objects (e.g., toys, bags, wallets, electronic devices).

[0189] Referring to FIG. 6e, the processor (120) may select an area (623) including a sofa within the environment (607). In one embodiment, the processor (120) may select an area (624) including a table within the environment (607). However, the present invention is not limited thereto.

[0190] In one embodiment, the processor (120) can select (and / or identify) at least one object from among one or more objects that can overlap visual objects within the environment (607). In one embodiment, the processor (120) can select (and / or identify) at least one area (623, 624) based on the at least one selected object. For example, the processor (120) can select at least one object from among a sofa and a table, and select (and / or identify) at least one area (623, 624) corresponding to the selected object.

[0191] In one embodiment, the processor (120) may select (and / or identify) at least one object adjacent to the line of sight (521) of the user (510) among one or more objects capable of overlapping visual objects within the environment (607). Here, at least one object being adjacent to the line of sight (521) may mean that at least one object is located within a specified distance from the line of sight (521), but is not limited thereto.

[0192] In one embodiment, the processor (120) may select (and / or identify) a specified number of objects from among one or more objects that can overlap visual objects within the environment (607). Here, the specified number may be the number of objects required to increase the size of the iris of the user (510). The specified number may vary depending on the brightness of the environment (607). For example, the specified number when the environment (607) is bright may be less than the specified number when the environment (607) is dark.

[0193] In one embodiment, the processor (120) may superimpose (or overlay) a visual object on at least one selected region (623, 624). For example, the processor (120) may generate a visual object having a shape corresponding to at least one selected object, and superimpose (or overlay) the generated visual object on at least one selected region (623, 624). In one embodiment, the processor (120) may superimpose (or overlay) a layer including a visual object on an image including at least one selected region (623, 624). In one embodiment, the processor (120) may superimpose (or overlay) a layer including a visual object corresponding to at least one selected object on an image including at least one selected region (623, 624). The correspondence of a visual object to at least one selected object may mean that the size, shape, and relative position of the visual object within the layer correspond to the size, shape, and relative position of the at least one selected object within the image. For example, the generated visual object may be brighter than the original object in the environment (607). Here, overlaying (or overlaying) a visual object may mean displaying the visual object through at least one display (250) in the wearable device (200) of FIG. 2A and / or FIG. 2B. For example, overlaying (or overlaying) a visual object may mean displaying the visual object through at least one display (350-1, 350-2) in the wearable device (300) of FIG. 3A and / or FIG. 3B. For example, adjusting (e.g., increasing) brightness may mean overlaying a transparent and / or translucent layer on an image displayed through at least one display (350-1, 350-2) to provide augmented reality (AR), virtual reality (VR), or mixed reality (MR). Here, the transparent and / or translucent layer may have a brightness greater than or equal to a specified brightness in a selected area of ​​the image.A layer can be transparent in areas other than the selected area of ​​the image. A layer can have a brightness higher than the specified brightness in areas other than the selected area of ​​the image.

In one embodiment, the processor (120) may authenticate a user (510) based on an iris included in an image for iris recognition acquired while the brightness of at least one area (623, 624) is adjusted.

[0198] As described above, when adjusting brightness for iris recognition, the electronic device (401) can reduce discomfort (e.g., glare) to the user (510) by optimizing the intensity of light for iris recognition. When adjusting brightness for iris recognition, the electronic device (401) can provide the user (510) with a naturally adjusted brightness environment (607) by superimposing an image object that is brighter than an object located in the environment (607) (or, minimize the user's (510) sense of incongruity).
