[0081] According to various embodiments, the wearable device (200) may include a lens structure (270). The lens structure (270) may refract at least a portion of light. For example, the lens structure (270) may be a prescription lens having refractive power. According to one embodiment, the lens structure (270) may be positioned behind (e.g., in the +Y direction) the second window member of the display member (201). For example, the lens structure (270) may be positioned between the display member (201) and the user's eye. For example, the lens structure (270) may face the display member.

[0082] According to various embodiments, the housing (210) may include a hinge cover (227) that may conceal a portion of the hinge structure (229). Another portion of the hinge structure (229) may be accommodated or concealed between the inner case (231) and the outer case (233), which will be described later.

[0083] According to various embodiments, the wearable member (203) may include an inner case (231) and an outer case (233). The inner case (231) is, for example, a case configured to face or directly contact the user's body, and may be made of a material with low thermal conductivity, for example, a synthetic resin. According to one embodiment, the inner case (231) may include an inner side facing the user's body (e.g., the inner side (231c) of FIG. 2A). The outer case (233) may include, for example, a material capable of at least partially transmitting heat (e.g., a metal material) and may be coupled to face the inner case (231). According to one embodiment, the outer case (233) may include an outer side opposite the inner side (231c) (e.g., the outer side (231d) of FIG. 2A). In one embodiment, at least one of the circuit board (241) or the speaker module (245) may be accommodated in a space separated from the battery (243) within the wearable member (203). In the illustrated embodiment, the inner case (231) may include a first case (231a) including the circuit board (241) or the speaker module (245) and a second case (231b) accommodating the battery (243), and the outer case (233) may include a third case (233a) coupled to face the first case (231a) and a fourth case (233b) coupled to face the second case (231b). For example, a first case (231a) and a third case (233a) may be combined (hereinafter, “first case portion (231a, 233a)”) to accommodate a circuit board (241) and / or a speaker module (245), and a second case (231b) and a fourth case (233b) may be combined (hereinafter, “second case portion (231b, 233b)”) to accommodate a battery (243).

[0084] According to various embodiments, the first case portion (231a, 233a) is rotatably connected to the lens frame (202) via a hinge structure (229), and the second case portion (231b, 233b) can be connected or mounted to an end of the first case portion (231a, 233a) via a connecting member (235). In some embodiments, among the connecting members (235), a portion that comes into contact with the user's body can be made of a material having low thermal conductivity, for example, an elastic material such as silicone, polyurethane, or rubber, and a portion that does not come into contact with the user's body can be made of a material having high thermal conductivity, for example, a metal material. For example, when heat is generated in the circuit board (241) or the battery (243), the connecting member (235) can block the heat from being transferred to the portion that comes into contact with the user's body, and can disperse or release the heat through the portion that does not come into contact with the user's body. According to one embodiment, a portion of the connecting member (235) that is configured to come into contact with the user's body may be interpreted as a part of the inner case (231), and a portion of the connecting member (235) that is not configured to come into contact with the user's body may be interpreted as a part of the outer case (233). According to one embodiment (not shown), the first case (231a) and the second case (231b) may be configured as an integral body without the connecting member (235), and the third case (233a) and the fourth case (233b) may be configured as an integral body without the connecting member (235). According to various embodiments, in addition to the illustrated components, other components (e.g., the antenna module (197) of FIG. 1) may be further included, and information about objects or environments may be provided from an external electronic device (e.g., the electronic device (102, 104) or server (108) of FIG. 1) through a network (e.g., the first network (198) or the second network (199) of FIG. 1) using the communication module (190).

[0085] In FIGS. 2A to 2C, only the wearable device (200) is illustrated and described, but it is not limited thereto, and some components of the wearable device (200) illustrated in FIGS. 2A to 2C may also be included in electronic devices such as smartphones and tablet PCs.

[0086] The wearable device (200) according to various embodiments of the present document can identify whether the user (210) is wearing the wearable device (100) through a proximity sensor included in the wearable device (200). Alternatively, the wearable device (200) according to various embodiments of the present document can determine whether the wearable device (200) is worn by the user (210) based on whether the frame of the wearable device (200) is unfolded (e.g., unfolded state) and whether proximity of the user (210) is detected while the frame of the wearable device (200) is unfolded, through an angle sensor provided in a hinge portion of the wearable device (200).

[0087] FIG. 3 illustrates an eye tracking camera structure of a wearable device according to various embodiments. Referring to FIG. 3, a wearable device (300) (e.g., a glasses-type device) may include an ET (eye tracking) camera (310), a display (321), an input optical member (322), a first waveguide (323), an output optical member (324), a first splitter (341), a second waveguide (342), and a second splitter (343).

[0088] According to various embodiments, the user's pupil (330) may be captured by the ET camera (310) through a first splitter (341) (e.g., a splitter for gaze tracking), a second waveguide (342), and a second splitter (343). The ET camera (310) may detect the pupil (330) in the captured image and track the user's gaze by confirming the movement of the detected pupil (330).

[0089] According to various embodiments, an image output through the display (321) may be reflected through the input optical member (322) and the first waveguide (323) and displayed through the output optical member (324). The wearable device (300) may output an image through the display (321) and at the same time track the user's gaze by checking the movement of the user's pupils (330).

[0090] FIG. 4 is an exemplary drawing for explaining a function or operation of an electronic device according to one embodiment of the present document to determine whether a user wearing an electronic device (e.g., an electronic device (101) of FIG. 1, a wearable device (200) of FIGS. 2A, 2B, and 2C, a wearable device (300) of FIG. 3) is a legitimate user based on various parameters.

[0091] FIG. 5a is an example drawing for explaining an eye image (500) according to one embodiment of the present document.

[0092] FIG. 5b is an exemplary drawing for explaining a glint ID (identification) (e.g., a first glint (510), a second glint (520), a third glint (530), a fourth glint (540), a fifth glint (550), a sixth glint (560), a seventh glint (570), an eighth glint (580)) according to one embodiment of the present document.

[0093] FIG. 5c is an exemplary drawing for explaining an eye image (500) acquired when a user is wearing glasses according to one embodiment of the present document.

[0094] Referring to FIG. 4, an electronic device (e.g., the processor (120) of FIG. 1) according to an embodiment of the present document may, in operation 410, acquire an eye image (500) of a user through at least one camera (e.g., the first camera module (251)). Referring to FIG. 5A, the eye image (500) according to an embodiment of the present document may include an iris, a pupil, a sclera, and a glint. The glint according to an embodiment of the present document may refer to a reflected light and / or a position thereof that appears when light output from a light-emitting module for gaze tracking is reflected by the user's eye. Referring to FIG. 5B, the glint according to an embodiment of the present document may have a unique identification number (e.g., a glint ID) for each glint. The glint ID according to an embodiment of the present document may correspond to an ID of a light-emitting module for gaze tracking. An electronic device according to an embodiment of the present document may perform 3D eye modeling based on a glint ID. When identifying a glint ID, the electronic device according to an embodiment of the present document may extract the glint ID using a deep learning method. The electronic device according to an embodiment of the present document may identify a plurality of glints using a deep learning method and then identify the glint ID through the position and relative relationship of each glint. Referring to FIG. 5C, an eye image (500) according to an embodiment of the present document may include an optical element (590) when a user wears glasses. The optical element (590) according to an embodiment of the present document may be captured in different patterns depending on the characteristics of the glasses lens worn by the user. Operation 410 according to an embodiment of the present document may be performed through various authentication processes, such as when it is detected that the electronic device is worn by the user or when iris authentication is required.

[0095] Again, referring to FIG. 4, an electronic device according to one embodiment of the present document may determine, at operation 420, whether a user wearing the electronic device is a legitimate user based on an eye image (500) acquired according to operation 410.

[0096] In one embodiment, a "legitimate user" may refer to a user registered as a user of an electronic device through prior authentication. According to one embodiment of the present document, the term "legitimate user" may also refer to a user who is not a fake user (e.g., a user wearing an electronic device who attempts iris authentication using an eye image captured by a camera module rather than their own eyes).

[0097] An electronic device according to one embodiment of the present document may determine whether a user of the electronic device is a legitimate user based on at least one of position information of a glint (e.g., a first glint (510), a second glint (520), a third glint (530), a fourth glint (540), a fifth glint (550), a sixth glint (560), a seventh glint (570), and an eighth glint (580)) for an eye image, an oval shape of a pupil, an oval shape of an iris, or whether glasses are worn. In the case of false authentication using an output image of an eye tracking (ET) camera, there may be a high probability that the image was taken using a camera other than the eye tracking camera of the electronic device. This may mean that the oval shape of the pupil and / or the oval shape of the iris of the eye image attempting false authentication may be different from the oval shape of the pupil and / or the oval shape of the iris of the eye image of the user wearing the electronic device. Accordingly, the electronic device according to one embodiment of the present document may determine whether the user attempting authentication (e.g., iris authentication) is a false user (e.g., an "eye image" rather than a real eye) based on the oval shape of the pupil and / or the oval shape of the iris. Information about the oval shape of the pupil and / or the iris according to one embodiment of the present document may be stored in the electronic device or may be stored in a server connected to the electronic device. An electronic device according to one embodiment of the present document can determine whether a user attempting authentication is a legitimate user by comparing the elliptical shape of a pupil and / or an elliptical shape of an iris stored in the electronic device and / or a server with the elliptical shape of a pupil and / or an elliptical shape of an iris acquired by an eye tracking camera (e.g., a first camera (251)) of the electronic device.

[0098] In addition, in the case of glint, it may be a pattern that cannot appear when an eye image is captured by a general camera. Accordingly, an electronic device according to an embodiment of the present document can determine whether a user attempting authentication is a legitimate user by using glint location information. If a user attempting authentication may attempt false authentication through a camera for iris authentication. In this case, the infrared LED pattern used in iris recognition may be different from the infrared LED pattern used in gaze tracking. For example, in the case of gaze tracking, all eight infrared LEDs with IDs 0 to 7 may output light, while in the case of iris recognition, only one or two infrared LEDs, such as infrared ID 1 or infrared IDs 1 and 2, may output this light. This is to improve the accuracy of the iris recognition algorithm. An electronic device according to one embodiment of the present document knows which infrared LED is turned on during iris authentication, and thus, in the case of iris authentication, may know the expected glint ID information and location. Accordingly, when a user attempting authentication attempts false authentication, the electronic device can determine whether the user attempting authentication is a legitimate user by comparing the expected glint ID information and location with the glint ID information and location of the eye image used during false authentication. Information about the glint ID information and location according to one embodiment of the present document may be stored in the electronic device or may be stored in a server connected to the electronic device. The electronic device according to one embodiment of the present document can determine whether the user attempting authentication is a legitimate user by comparing the glint ID information and location stored in the electronic device and / or the server with glint ID information and location acquired by an eye tracking camera (e.g., the first camera (251)) of the electronic device.

[0099] An electronic device according to an embodiment of the present document may determine whether a user attempting authentication is a legitimate user by comparing a pattern of an optical element (590) (e.g., comparing a pattern of an optical element (590) included in a false eye image and an eye image (500) captured by an actual first camera module (251). Information about the optical element (590) according to an embodiment of the present document may be stored in the electronic device or a server connected to the electronic device. An electronic device according to an embodiment of the present document may determine whether a user attempting authentication is a legitimate user by comparing a pattern of an optical element (590) stored in the electronic device and / or the server with a pattern of an optical element (590) acquired by an eye tracking camera (e.g., the first camera (251)) of the electronic device.

[0100] An electronic device according to an embodiment of the present document may identify a gaze direction of a user performing authentication and use information about the identified gaze direction when determining whether the user is a fake user. Eye features (e.g., an oval shape of a pupil and / or an oval shape of an iris, etc.) according to an embodiment of the present document may be stored in the electronic device according to the gaze direction or may be stored in a server connected to the electronic device. An electronic device according to an embodiment of the present document may determine whether a user attempting authentication is a legitimate user by comparing information about eye features (e.g., an oval shape of a pupil and / or an oval shape of an iris, etc.) and gaze direction stored in the electronic device and / or the server with information about eye features (e.g., an oval shape of a pupil and / or an oval shape of an iris, etc.) and gaze direction acquired by an eye tracking camera (e.g., a first camera (251)) of the electronic device. Operation 420 according to an embodiment of the present document may be performed through various authentication processes, such as when it is detected that the electronic device is worn by the user or when iris authentication is required.

[0101] FIG. 6 is an exemplary drawing for explaining a function or operation of changing the brightness of a first virtual object (710) and / or the brightness of an application execution screen in order to determine whether a user wearing the electronic device is a false user, in accordance with one embodiment of the present document (e.g., the electronic device (101) of FIG. 1, the wearable device (200) of FIGS. 2A, 2B, and 2C, and the wearable device (300) of FIG. 3). FIG. 7 is an exemplary drawing for explaining the function or operation described in FIG. 6 from a user interface perspective.

[0102] Referring to FIGS. 6 and 7, an electronic device according to an embodiment of the present document may, in operation 610, identify the brightness of a first virtual object (710), and then control a display module (e.g., the display module (160) of FIG. 1) so that the brightness of the first virtual object (710) is output as a value brighter than the current brightness value. An electronic device according to an embodiment of the present document may, after identifying a background brightness value using at least one sensor (e.g., an illuminance sensor), not adjust the brightness value of the first virtual object (710) if the background brightness value exceeds a specified brightness value. A first virtual object (710) according to an embodiment of the present document may include a first virtual object (710) located in a direction where a user's gaze is directed and / or an execution screen of an application requiring iris authentication. To this end, an electronic device according to an embodiment of the present document may, after operation 610, additionally perform a function or operation of identifying a user's gaze direction. Operation 610 according to one embodiment of this document may be understood by a person skilled in the art as a function or operation of changing the brightness of only an object located in the direction of the user's gaze, rather than the overall brightness of the screen included in the user's field of view.

[0103] According to an embodiment of the present document, the electronic device may determine, in operation 620, whether the pupil size of the user's eye image changes according to a change in the brightness value of the first virtual object (710). According to an embodiment of the present document, in operation 630, the electronic device may determine, based on the determination result of operation 620, whether the user performing authentication is a false user. For example, if the pupil size changes according to operation 610, the electronic device according to an embodiment of the present document may determine that the user is a legitimate user (e.g., determine that the actual user is wearing the electronic device). Conversely, if the pupil size change is not detected according to operation 610, the electronic device according to an embodiment of the present document may determine that the user performing authentication is not a legitimate user (e.g., determine that authentication is being performed using an eye image). Operations 610 to 630 according to an embodiment of the present document may be performed through various authentication processes, such as when it is detected that the electronic device is worn by the user or when iris authentication is required.

[0104] FIG. 8 is an exemplary diagram illustrating a function or operation of changing the display position of a first virtual object (710) in order to determine whether a user wearing the electronic device is a false user, according to an embodiment of the present document. FIG. 9 is an exemplary diagram illustrating the function or operation described in FIG. 8 from a user interface perspective.

[0105] Referring to FIGS. 8 and 9, an electronic device according to an embodiment of the present document (e.g., the electronic device (101) of FIG. 1, the wearable device (200) of FIGS. 2A, 2B, and 2C, and the wearable device (300) of FIG. 3) may identify the brightness of a background in operation 810. The electronic device according to an embodiment of the present document may identify the brightness of a screen included in a user's field of view or may identify the brightness of the background through a function or operation of detecting the brightness of the real world using a light sensor.

[0106] According to an embodiment of the present document, in operation 820, the electronic device may move the display position of the second virtual object (e.g., the second virtual object (910) of FIG. 9) (e.g., the iris authentication screen) to an area having a bright background (e.g., an area including a brightness value greater than a specified threshold value at a specified rate or more). According to an embodiment of the present document, in operation 830, the electronic device may determine whether the direction of the user's gaze moves. According to an embodiment of the present document, in operation 840, the wearable device may determine whether the user performing authentication is a false user based on the determination result of operation 830. For example, if the user's gaze (e.g., gaze direction) toward the second virtual object (910) moves in accordance with the movement of the second virtual object (910), the electronic device may determine that the user performing authentication is a legitimate user (e.g., an actual user). For example, if the user's gaze toward the second virtual object (910) does not move in accordance with the movement of the second virtual object (910), the electronic device may determine that the user performing authentication is a false user.

[0107] In one embodiment, in the examples described above, it has been described that determining whether the user performing authentication is a false user is performed by moving the display position of the iris authentication screen as a second virtual object to an area with a bright background (e.g., an area including a brightness value higher than a specified threshold value at a specified rate or more), but the present invention is not limited thereto. For example, the electronic device may change (e.g., increase) the brightness of the iris authentication screen without changing the display position of the iris authentication screen as a second virtual object. The electronic device may determine the user performing authentication as a legitimate user based on the change in the size of the pupil included in the eye image due to the change in the brightness of the iris authentication screen. The electronic device may determine the user performing authentication as a false user based on the fact that the size of the pupil included in the eye image does not change due to the change in the brightness of the iris authentication screen.

[0108] An electronic device according to an embodiment of the present document may, when the brightness of the background is substantially uniform, move the display position of the second virtual object (910) (e.g., iris authentication screen) in a specified direction (e.g., from left to right) and then perform operation 840. Alternatively, an electronic device according to an embodiment of the present document may, when the brightness of the background is substantially uniform, change the brightness value of a specified area of ​​the background to be brighter than the current brightness value and then move the second virtual object (910) (e.g., iris authentication screen) to the area where the brightness has been changed.

[0109] Operations 810 to 840 according to one embodiment of the present document may be performed through various authentication processes, such as when it is detected that an electronic device is worn by a user, when iris authentication is required, etc.

[0110] FIG. 10 is an exemplary drawing for explaining a function or operation of changing the brightness and position of a first virtual object (710) in order to determine whether a user wearing the electronic device is a false user, according to an embodiment of the present document.

[0111] Fig. 11 is an example drawing for explaining the function or operation described in Fig. 10 from a user interface perspective.

[0112] Referring to FIGS. 10 and 11, an electronic device according to an embodiment of the present document (e.g., the electronic device 101 of FIG. 1, the wearable device 200 of FIGS. 2A, 2B, and 2C, and the wearable device 300 of FIG. 3) may, in operation 1010, display a virtual object (e.g., a third virtual object 1100)) having a first brightness at a first location by changing the brightness and position to a second brightness and position. In operation 1020, the electronic device according to an embodiment of the present document may display a virtual object (e.g., a fourth virtual object 1110) having a second brightness at a second location by changing the brightness and position to a third brightness and position (e.g., so that a fifth virtual object 1120 is displayed). For example, the electronic device may control a display module so that the brightness and position of the virtual object are changed in operations 1010 and 1020. According to an embodiment of the present document, in operation 1030, an electronic device may determine whether a user performing authentication is a false user based on an expected pupil size according to a change in brightness. Since the electronic device according to an embodiment of the present document knows the brightness of virtual objects (e.g., the third virtual object (1100), the fourth virtual object (1110), and the fifth virtual object (1120)), the electronic device may know the expected pupil size corresponding to each brightness through deep learning and / or user history information. Accordingly, the electronic device according to an embodiment of the present document may determine whether a user performing authentication is a false user based on an expected pupil size according to a change in brightness. In addition, the wearable electronic device may determine whether a user performing authentication is a false user by checking a change in the user's gaze along with a change in the pupil size in response to a change in the position of a virtual object (e.g., the third virtual object (1100), the fourth virtual object (1110), and the fifth virtual object (1120)).Through this, the accuracy of determining whether a user performing authentication is a false user can be increased. An electronic device according to one embodiment of the present document can also perform the function or operation illustrated in FIG. 10 by only changing the brightness of a virtual object (e.g., the third virtual object (1100), the fourth virtual object (1110), and the fifth virtual object (1120)) without changing its position.

[0113] An electronic device according to an embodiment of the present document may determine whether a user performing authentication is performing false authentication based on user history information. FIG. 12 is an exemplary diagram for explaining a function or operation of an electronic device according to an embodiment of the present document determining whether a user performing authentication is a false user based on user history information. Referring to FIG. 12, an electronic device according to an embodiment of the present document (e.g., the electronic device 101 of FIG. 1 , the wearable device 200 of FIGS. 2A, 2B, and 2C , and the wearable device 300 of FIG. 3 ) may, in operation 1210, display virtual objects (e.g., a third virtual object 1100, a fourth virtual object 1110, and a fifth virtual object 1120) by changing their brightness and position in a specified order. According to an embodiment of the present document, in operation 1220, an electronic device may determine whether a change in pupil size is performed according to a change in brightness and position of a virtual object (e.g., a third virtual object (1100), a fourth virtual object (1110), a fifth virtual object (1120)) based on user history information. According to an embodiment of the present document, in operation 1230, an electronic device may determine whether a user performing authentication is a false user based on the determination result of operation 1220. For example, according to an embodiment of the present document, an electronic device may store a change in pupil size according to the order in which virtual objects (e.g., a third virtual object (1100), a fourth virtual object (1110), a fifth virtual object (1120)) are displayed as user history information, and may determine whether a change in pupil size is performed according to the stored user history information. For example, before performing the operations of FIG. 12, the electronic device may store the change in pupil size in memory as user history information while the brightness and position of the virtual object are changed in a specified order.The electronic device can acquire changes in pupil size while the brightness and position of the virtual object are changed in a specified order after the user history information is stored in the memory. The electronic device can determine the user performing authentication as a legitimate user based on whether the acquired change in pupil size corresponds to the change in pupil size stored as the user history information. The electronic device can determine the user performing authentication as a false user based on whether the acquired change in pupil size does not correspond to the change in pupil size stored as the user history information.

[0114] Operations 1010 to 1030 according to one embodiment of this document may be performed through various authentication processes, such as when it is detected that an electronic device is worn by a user, when iris authentication is required, etc.

[0115] According to one embodiment of the present document, it is possible to identify whether a user performing authentication is a false user based on changes in the size and / or shape of a glint by adjusting the brightness and / or on / off pattern of a light-emitting module for eye tracking. According to one embodiment of the present document, in the case of false authentication, since the properties of the glint do not change even if the brightness and pattern of the light-emitting module for eye tracking are adjusted, it is possible to determine whether a user performing authentication is a false user based on this.
