Description

Wearable electronic device including a lens actuator

[0001] Embodiments of the present disclosure relate to wearable electronic devices, for example, wearable electronic devices including a lens actuator.

[0002] With the advancement of electronics, information, and communication technologies, a variety of functions are being integrated into a single electronic device. For example, electronic devices (e.g., smartphones) incorporate functions such as audio playback, imaging, and electronic notebooks in addition to communication functions. Furthermore, smartphones can be equipped with even more diverse functions through the installation of additional applications. In addition to executing pre-installed applications or stored functions, electronic devices can also access servers or other electronic devices via wired or wireless means to receive a variety of information in real time.

[0003] As the use of electronic devices becomes more commonplace, user demand for portability and usability may increase. This demand has led to the commercialization of wearable electronic devices (hereinafter referred to as "wearable electronic devices") that can be worn on the body, similar to wristwatches or glasses. Among wearable electronic devices, those that can be worn on the face can be useful for implementing virtual reality or augmented reality. For example, wearable electronic devices can provide a three-dimensional image of a virtual space within a game played on a television or computer monitor, while blocking the image of the actual space the user is in, thereby implementing virtual reality. Other types of wearable electronic devices can provide an environment where the user can visually perceive the actual image of the space they are in, while presenting a virtual image to provide the user with various visual information, thereby implementing augmented reality. A "real image of the space" can include, for example, an image captured by a camera or an image transmitted through see-through optics. A 'virtual image' may include information about the space in which the user is staying and / or information about various objects within the space.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art in connection with the present disclosure.

[0021] Wearable electronic devices that implement augmented reality, virtual reality, mixed reality, and / or extended reality can generally be used while worn on the user's head or face. For example, a display that outputs visual information may be placed at a relatively close distance from the user's eyes. Depending on the user's eyesight, body type, and / or wearing condition, there may be variations in the performance (e.g., image quality) of the display as perceived by the user. This variation in performance of the wearable electronic device as perceived by the user can be suppressed by guiding or focusing the visual information output from the display to the user's eyes using an optical system (e.g., a lens assembly) that can adjust the refractive power or focal length. However, in lightweight wearable electronic devices that are designed to be comfortable to wear or reduce user fatigue, it may be difficult to incorporate a structure that allows the user to conveniently adjust the refractive power or focal length according to their physical conditions.

[0022] One embodiment of the present disclosure is intended to at least resolve the above-described problems and / or disadvantages and at least provide the advantages described below, and provides a wearable electronic device including a lens driving unit that provides a comfortable wearing experience to a user while implementing a usage environment that meets physical requirements.

While the exemplary embodiments disclosed in the following description include numerous specific details to aid understanding, they are to be considered as one example of various exemplary embodiments. Accordingly, those skilled in the art will appreciate that various modifications and variations of the various implementations described herein may be made without departing from the scope and spirit of the disclosure.

The electronic device (101) or the wearable electronic device (200, 300) may process the result as is or additionally and provide it as at least a part of a response to the request. For example, an external electronic device (102) renders content data executed in an application and transmits it to an electronic device (101) or a wearable electronic device (200, 300), and the electronic device (101) or wearable electronic device (200, 300) that receives the data can output the content data to a display module.When the electronic device (101) or the wearable electronic device (200, 300) detects user movement through an inertial measurement unit sensor or the like, the processor (e.g., the processor (120) of FIG. 1) of the electronic device (101) or the wearable electronic device (200, 300) may correct the rendering data received from the external electronic device (102) based on the movement information and output the corrected data to the display module. Alternatively, the processor may transmit the movement information to the external electronic device (102) and request rendering so that the screen data is updated accordingly. According to various embodiments, the external electronic device (102) may be various types of devices, such as a case device that can store and charge the electronic device (101).

For example, the display member (201) may guide the output image of the light output module (211) to the user's eyes by including at least one diffractive optical element, a holographic optical element, or a reflective element, and / or by including an optical waveguide.

[0061] According to one embodiment of the present disclosure, the camera module (250) can capture still images and / or moving images. According to one embodiment, the camera module (250) is disposed within a lens frame and can be disposed around the display member (201).

[0062] According to one embodiment of the present disclosure, the first camera module (251) can capture and / or recognize the trajectory of the user's eye (e.g., pupil, iris) or gaze. According to one embodiment of the present disclosure, the first camera module (251) can periodically or aperiodically transmit information related to the trajectory of the user's eye or gaze (e.g., trajectory information) to a processor (e.g., processor (120) of FIG. 1).

[0063] According to one embodiment of the present disclosure, the second camera module (253) can capture an external image.

According to one embodiment of the present disclosure, the third camera module (255) can be used for 3 degrees of freedom (3DoF), 6DoF head tracking, position (space, environment) recognition, and / or movement recognition. According to one embodiment of the present disclosure, the second camera module (253) can also be used for hand detection and tracking, and user gesture recognition. According to one embodiment of the present disclosure, at least one of the first camera module (251) to the third camera module (255) can be replaced with a sensor module (e.g., a LiDAR sensor). For example, the sensor module can include at least one of a vertical cavity surface emitting laser (VCSEL), an infrared sensor, and / or a photodiode.

[0065] According to one embodiment, the wearable electronic device (200) may include a pair of display elements (201) arranged parallel to one side of each other. For example, a user may wear the wearable electronic device (200) on the face, and the display elements (201) may be arranged to correspond to any one of the user's visual eyes while the wearable electronic device (200) is worn on the user's face. In one embodiment, when the wearable electronic device (200) includes a pair of display elements (201), the wearable electronic device (200) may provide visual information to the user through any one of the display elements (201) and / or through each display element (201).

[0066] According to one embodiment, the wearable electronic device (200) may include at least one wearing member (202a, 202b) extending from or rotatably coupled to the display member (201). In the illustrated embodiment, the wearing member (202a, 202b) may be exemplified as a structure that is rotatably coupled (or connected) to the display member (201) by a hinge structure (H). For example, the wearing member (202a, 202b) may be in a position overlapped or folded with the display member (201), in which case the user may easily carry or store the wearable electronic device (200). In one embodiment, the wearable electronic device (200) can be easily worn on the user's face at a position where the wearing member (202a, 202b) is rotated by a specified angle (e.g., approximately 90 degrees) from a position overlapping the display member (201). For example, the wearable electronic device (200) can be stably worn by supporting the display member (201) on the user's face and supporting the wearing member (202a, 202b) on the side of the user's head (e.g., the ear).

[0067] FIGS. 3 and 4 are drawings showing the front and back of a wearable electronic device (300) according to one embodiment.

[0068] Referring to FIGS. 3 and 4, in one embodiment, camera modules (311, 312, 313, 314, 315, 316) and / or depth sensors (317) for obtaining information related to the surrounding environment of the wearable electronic device (300) may be arranged on the first surface (310) of the housing.

[0069] In one embodiment, the camera modules (311, 312) can acquire images related to the environment surrounding the wearable electronic device.

[0070] In one embodiment, the camera modules (313, 314, 315, 316) can acquire images while the wearable electronic device is worn by a user. The camera modules (313, 314, 315, 316) can be used for hand detection and tracking, and user gesture (e.g., hand movement) recognition. The camera modules (313, 314, 315, 316) can be used for 3DoF, 6DoF head tracking, position (spatial, environmental) recognition, and / or movement recognition. In one embodiment, the camera modules (311, 312) can also be used for hand detection and tracking, and user gesture.

[0071] In one embodiment, the depth sensor (317) may be configured to transmit a signal and receive a signal reflected from a subject, and may be used for purposes such as time of flight (TOF) to determine the distance to an object. Instead of or in addition to the depth sensor (317), camera modules (313, 314, 315, 316) may determine the distance to an object.

[0072] According to one embodiment, a camera module (325, 326) for facial recognition and / or a display (321) (and / or a lens) may be disposed on the second side (320) of the housing. In the illustrated embodiment, the display (321) is illustrated as being visually exposed on the second side (320), but it should be noted that the embodiments of the present disclosure are not limited thereto. For example, a light source that actually outputs visual information or images may be disposed on the inner side of the second side (320), and a lens assembly aligned with the light source may be visually exposed on the second side (320). In one embodiment, the display (321) may be understood to include such a light source and lens assembly.

[0073] In one embodiment, a face recognition camera module (325, 326) adjacent to the display may be used to recognize a user's face, or may recognize and / or track both eyes of the user.

[0074] In one embodiment, the display (321) (and / or lens) may be disposed on the second side (320) of the wearable electronic device (300). In one embodiment, the wearable electronic device (300) may not include some of the camera module(s) (e.g., the camera module indicated as '315' or '316') among the plurality of camera modules (313, 314, 315, 316). Although not illustrated in FIGS. 3 and 4 , the wearable electronic device (300) may further include at least one of the configurations illustrated in FIG. 2 .

[0075] As described above, according to one embodiment, the wearable electronic device (300) may have a form factor for being worn on a user's head. The wearable electronic device (300) may further include a strap for being fixed on a body part of the user, and / or a wearing member (e.g., the wearing member (202a, 202b) of FIG. 2). The wearable electronic device (300) may provide a user experience based on augmented reality, virtual reality, and / or mixed reality while being worn on the user's head.

[0076] FIG. 5 is a diagram illustrating a wearable electronic device (400) (e.g., the electronic device (101) of FIG. 1 and / or the wearable electronic devices (200, 300) of FIGS. 2 to 4) according to one embodiment of the present disclosure. FIG. 6 is a side view illustrating the wearable electronic device (400) of FIG. 5 according to one embodiment of the present disclosure.

[0077] Referring to FIGS. 5 and 6, the wearable electronic device (400) may include a housing (410) (or lens frame), a wearing member (402a, 402b), an input unit (402), at least one display (e.g., a display module (160) of FIG. 1 and / or a display (421) of FIG. 7), a lens assembly (401L, 401R), a driving unit (403), and / or a processor (e.g., a processor (120, 420) of FIG. 1 or 7). In the illustrated embodiment, when the wearable electronic device (400) is worn on a user's body (U), it may be understood that the lens assembly indicated by '401L' is arranged to correspond to the user's left eye, and the lens assembly indicated by '401R' is arranged to correspond to the user's right eye.

[0078] According to one embodiment, the processor (120, 420) can control the driving unit (403) based on a user input detected at the input unit (402), thereby adjusting the focal length or refractive power of the lens assembly (401L, 401R). For example, the focal length or refractive power can be adjusted by moving the lenses (411L, 411R, 413L, 413R) of the lens assembly (401L, 401R) by the driving unit (403). In one embodiment, the input unit (402) may be substantially disposed on the wearable member (402a, 402b), and the processor (120, 420) may advance or retract the lenses (411L, 411R, 413L, 413R)(s) of the lens assembly (401L, 401R) in response to a forward-facing user input (F) or a rearward-facing user input (B). In one embodiment, the input unit (402) may detect a pressure according to the user input, and the processor (120, 420) may determine a distance by which the lenses (411L, 411R, 413L, 413R)(s) of the lens assembly (401L, 401R) move based on the detected pressure. In one embodiment, the input unit (402) is arranged on the wearable member (402a, 402b) and is positioned on one side of the user's (U's) face when worn, so that the user (H) can easily operate the input unit (402) with a hand (H) (e.g., a finger).

[0079] According to one embodiment, the housing (410) may be implemented similarly to the wearable electronic device (200, 300) (or its housing) of FIG. 3 or FIG. 4, for example, and in one embodiment, may be implemented in the form of a lens frame for arranging the display member (201) of FIG. 2. When the wearable electronic device (400) is worn on the user's body (U), the housing (410) may be positioned to face the user's face or eyes (E). For example, by positioning the housing (410) to face the user's face, the wearable electronic device (400) may provide the user with a captured image or an image transmitted through see-through optics.

[0080] In one embodiment, the wearing member (402a, 402b) may be substantially the same as the wearing member (202a, 202b)(s) of FIG. 2, for example. In one embodiment, the wearing member (402a, 402b) may be implemented in a shape (e.g., a wearing strap) that extends from the housing (410) or the lens frame and forms a closed curve together with the housing (410) or the lens frame. In one embodiment, the wearing member (402a, 402b) may include a shaped portion made of a metal or synthetic resin material, and a flexible portion connecting the shaped portion. The term “flexible portion” may refer to a portion made of a material such as rubber, silicone, fiber, and / or leather, for example.

[0081] According to one embodiment, when the wearable electronic device (400) is worn on the user's body (U), the wearing member (402a, 402b) can support or maintain the housing (410) while being placed on the user's face. For example, the wearing member (402a, 402b) and / or the housing (410) can be combined to stably maintain the wearable electronic device (400) while being worn on the user's body (U). In one embodiment, the materials and shapes of the housing (410) and / or the wearing member (402a, 402b) can be combined in various ways, taking into account the wearing comfort or structural stability.

[0082] According to one embodiment, the input unit (402) is configured to detect a user input, for example, the user can adjust the refractive power or focal length of the lens assembly (401L, 401R) by manipulating the input unit (402). The input unit (402) can detect the user input and generate an electric signal by including, for example, at least one of a key (or button), a touch sensor, and / or a piezoelectric element. The wearable electronic device (400) and / or a processor (e.g., the processor (120, 420) of FIG. 1 or 7) can generate a control signal for adjusting the focal length or refractive power of the lens assembly (401L, 401R) based on the user input detected through the input unit (402). These control signals can, for example, operate the driving unit (403) and move the lenses (411L, 411R, 413L, 413R)(s).

[0083] According to one embodiment, the lenses (411L, 411R, 413L, 413R) within the lens assembly (401L, 401R) can move forward and backward in one direction. In one embodiment, the processor (120, 420) can generate a control signal for adjusting the focal length or refractive power of the lens assembly (401L, 401R) based on a user input corresponding to the direction of movement of the lenses (411L, 411R, 413L, 413R)(s). For example, the direction in which the input unit (402) is operated or the pressure applied to the input unit may vary depending on the user or the time of operation, and the processor (120, 420) can generate the control signal when a user input is detected in a direction that is substantially parallel to (or coincides with) the direction of movement of the lenses (411L, 411R, 413L, 413R)(s).

[0084] According to one embodiment, in detecting the input direction, "a direction substantially parallel to the direction of movement of the lenses (411L, 411R, 413L, 413R)" may be understood to include a direction inclined within an angle of approximately 15 degrees with respect to the direction of movement of the lenses (411L, 411R, 413L, 413R)(s). For example, when a user input is detected in a direction within an angle of approximately 15 degrees with respect to the direction of movement of the lenses (411L, 411R, 413L, 413R)(s), the processor (120, 420) may determine that the user wishes to adjust the focal length or refractive power of the lens assembly (401L, 401R) and may generate a signal for controlling the driving unit (403). In this way, since the movement direction of the lenses (411L, 411R, 413L, 413R)(s) and the user input direction in the wearable electronic device (400) according to the embodiment(s) of the present disclosure are set to be substantially parallel, the user can perform intuitive operations in adjusting the focal length or refractive power of the lens assembly (401L, 401R). In one embodiment, the “substantially parallel direction” is mentioned to include a direction inclined within an angle of approximately 15 degrees, but it should be noted that the embodiment(s) of the present disclosure are not limited thereto. For example, depending on the shape of the wearable electronic device (400) to be actually manufactured or the position of the input unit (402), a direction inclined within an angle of approximately 30 degrees can be understood as a “substantially parallel direction.”

[0085] In one embodiment, when the input unit (402) includes a piezoelectric element, the processor (120, 420) can detect the direction of the user input as well as the pressure applied by the user input using the input unit (402). In one embodiment, when the pressure according to the user input is detected, the processor (120, 420) can determine the distance to move the lens (411L, 411R, 413L, 413R)(s) from the current position based on the detected pressure. For example, in adjusting the focal length or refractive power based on the user input detected at the input unit (402), the processor (120, 420) can move the lens (411L, 411R, 413L, 413R)(s) by a distance proportional to the pressure according to the user input.

[0086] According to one embodiment, a display (421) (e.g., display module (160) of FIG. 1) may be disposed on at least one of the housing (410) (or lens frame) and / or the wearable member (402a, 402b) and may output information captured by the camera module (e.g., camera modules (180, 250, 311, 312, 313, 314, 315, 316) of FIGS. 1 to 4), information stored in the wearable electronic device (400), and / or information received by a communication module (e.g., communication module (190) of FIG. 1)) in a visual form. In one embodiment, when the housing (410) or the lens frame is configured to be disposed to face both eyes of the user, the wearable electronic device (400) may include multiple displays. For example, a wearable electronic device (400) may include multiple displays, thereby providing visual information to each of the user's eyes. In one embodiment, the visual information output by the multiple displays may be substantially identical or independent of each other.

[0087] In one embodiment, the lens assembly (401L, 401R) can focus or guide visual information output from the display (421) and provide it to the user. For example, the lens assembly (401L, 401R) can implement an optical path from the display (421) to the user's eye (E). In one embodiment, when the wearable electronic device (400) includes a plurality of displays (421), a plurality of lens assemblies (401L, 401R) can be provided corresponding to the number of displays (421). In one embodiment, the lens assembly (401L, 401R) may include at least one lens (411L, 411R, 413L, 413R), and the focal length or refractive power of the lens assembly (401L, 401R) may be adjusted by moving the lens (411L, 411R, 413L, 413R)(s) within the lens assembly (401L, 401R) or the housing (410). In one embodiment, when the lens assembly (401L, 401R) includes a plurality of lenses (411L, 411R, 413L, 413R), the focal length or refractive power of the lens assembly (401L, 401R) can be adjusted by moving at least one of the plurality of lenses (411L, 411R, 413L, 413R) forward or backward relative to the remaining lens(es).

[0088] As will be described later, when the lens assembly (401L, 401R) includes a first lens (411L, 411R) provided as one of at least one lens (411L, 411R, 413L, 413R) and a second lens (413L, 413R) provided as another of the at least one lens, one of the first lens (411L, 411R) and the second lens (413L, 413R) can move toward or away from the other. In one embodiment, when the wearable electronic device (400) is worn on the user's body, the second lens (413L, 413R) can move closer to the first lens (411L, 411R) or further away from the first lens (411L, 411R) by moving along a designated direction between the first lens (411L, 411R) and the user's eye (E). As a result, the refractive power of the wearable electronic device (400) and / or the lens assembly (401L, 401R) can be adjusted, and the user can use the wearable electronic device (400) in a state suitable for his / her physical condition (e.g., eyesight) by adjusting the position of the lens (411L, 411R, 413L, 413R)(s) using the input unit (402).

[0089] Examples of output images recognized by the user according to the focus adjustment status or refractive power of the wearable electronic device (400) or lens assembly (401L, 401R) are illustrated in FIGS. 12 and 13.

[0090] FIG. 12 is a diagram showing an example of an image output from a wearable electronic device (e.g., the electronic device (101) of FIG. 1 and / or the wearable electronic devices (200, 300, 400) of FIGS. 2 to 5) according to an embodiment of the present disclosure being recognized by a user. FIG. 13 is a diagram showing an example of an image output from a wearable electronic device (400) according to an embodiment of the present disclosure, or an example of the image being recognized by a user.

[0091] FIG. 12 can illustrate, for example, a state in which a user recognizes an output image in a state in which the refractive power is not adjusted to suit the user's eyesight. FIG. 13 can illustrate, for example, a state in which a user (U) recognizes an image output by a wearable electronic device (400) or a display (421), or an output image in a state in which the refractive power is adjusted to suit the user's eyesight. When the wearable electronic device (400) is worn on the face and the output image is recognized as in FIG. 12, the user (U) can adjust the focus or refractive power of the lens assembly (401L, 402R) by manipulating the input unit (402). For example, the user (U) can easily determine the focus adjustment state of the lens assembly (401L, 402R) through the image output by the wearable electronic device (400) or the display (421), and can conveniently perform focus adjustment through the input unit (402) according to the user's (U's) needs.

[0092] According to one embodiment, the driving unit (403) can be controlled by the processor (120, 420) to substantially move the lenses (411L, 411R, 413L, 413R)(s), thereby adjusting the focal length or refractive power of the lens assembly (401L, 401R). The configuration of the driving unit (403) or the driving structure of the lenses (411L, 411R, 413L, 413R)(s) will be further described with reference to FIGS. 7 and 8.

[0093] FIG. 7 is a drawing for explaining a driving structure in a wearable electronic device (e.g., the electronic device (101) of FIG. 1 and / or the wearable electronic devices (200, 300, 400) of FIGS. 2 to 6) according to one embodiment of the present disclosure. FIG. 8 is a drawing for explaining a driving structure in a wearable electronic device (400) according to one embodiment of the present disclosure.

[0094] Referring further to FIGS. 7 and 8, the drive unit (403) may include a first gear (433) (e.g., a pinion gear), a drive motor (431), and / or a second gear (435) (e.g., a rack gear). In one embodiment, the drive unit (403) and / or the second gear (435) may include guide rails (435u, 435b)(s) that guide movement of the first gear (433), and the gear teeth of the second gear (435) may be understood to be substantially arranged on the guide rails (435u, 435b). For example, depending on the rotation of the drive motor (431), either the first gear (433) or the second gear (435) may move linearly with respect to the housing (410) or the wearing member (402a, 402b). In the illustrated embodiment, a structure is illustrated in which one of the lenses (411L, 411R, 413L, 413R) of the lens assembly (401L, 401R) (e.g., the second lens (413L, 413R)) is disposed on the first gear (433), and it can be understood that the first gear (433) rotates by the driving motor (431) and moves linearly under the guidance of the second gear (435) or the guide rail (435u, 435b). As the first gear (433) moves linearly, the second lens (413L, 413R) can move closer to the first lens (411L, 411R) or away from the first lens (411L, 411R). For example, the second lens (413L, 413R) can be linearly moved between the first lens (411L, 411R) and the user's eye.

[0095] In one embodiment, the guide rails (435u, 435b) may include an upper rail (435u) and a lower rail (435b), and the second gear (435) may include gear teeth provided on either the upper rail (435u) or the lower rail (435b). In the illustrated embodiment, the gear teeth of the second gear (435) may be understood to be substantially provided on the lower rail (435b). In one embodiment, the first gear (433) is rotatably received between the upper rail (435u) and the lower rail (435b) and may linearly move on the second gear (435) while rotating in accordance with the operation of the drive motor (431).

[0096] According to one embodiment, the wearable electronic device (400) may include electrical wiring (429) (e.g., a flexible printed circuit board) provided between the processor (420) and the input unit (402) and / or the processor (420) and the driving unit (403). For example, the processor (420) may be electrically connected to the input unit (402) via the electrical wiring (429) to detect a user input using the input unit (402), and may generate a control signal and control the driving unit (403) based on the detected user input.

[0097] According to one embodiment, the display (421) may be disposed inside the housing (410) and may output visual information toward the user's eyes (E). The lenses (411L, 411R, 413L, 413R) may be substantially disposed between the display (421) and the user's eyes (E). For example, the visual information output from the display (421) may be focused or guided through the lenses (411L, 411R, 413L, 413R) and provided to the user's eyes (E). In one embodiment, the refractive power of the lens assembly (401L, 401R) can be adjusted by moving at least one of the lenses (411L, 411R, 413L, 413R) (e.g., the second lens (413L, 413R)) forward and backward in one direction between the display (421) and the user's eye (E), and the user (U) can adjust the refractive power of the lens assembly (401L, 401R) to a degree suitable for his or her eyesight by manipulating the input unit (403).

[0098] According to one embodiment, the processor (420) may output information about the movement distance of the lenses (411L, 411R, 413L, 413R)(s) based on a user input, and information about the refractive power (or focal length) of the lens assemblies (401L, 401R) corresponding to the current positions of the lenses (411L, 411R, 413L, 413R)(s) (hereinafter, “adjustment result information”). In one embodiment, the adjustment result information may be provided in the form of sound or in a visual form through the display (421). In one embodiment, the adjustment result information may be in a visual form, such as a number or a shape of a specified shape. For example, the shape provided as the adjustment result information may include a standard symbol used for measuring vision. The user, upon receiving this adjustment result information, can adjust the position of the lenses (411L, 411R, 413L, 413R)(s) to a position that suits his / her eyesight as needed. The operation of the wearable electronic device (400) or processor (420) will be further discussed with reference to FIG. 11.

[0099] FIG. 9 is a drawing for explaining a driving structure in a wearable electronic device (500) (e.g., the electronic device (101) of FIG. 1 and / or the wearable electronic devices (200, 300) of FIGS. 2 to 4) according to one embodiment of the present disclosure. FIG. 10 is a drawing for explaining a driving structure in a wearable electronic device (500) according to one embodiment of the present disclosure.

[0100] The embodiments of FIGS. 9 and 10 may differ from the preceding embodiments in the structure of the driving unit (503), and / or may differ from the preceding embodiments in the configuration in which the wearable electronic device (500) further includes a detection unit (504). In one embodiment, the detection unit (504) may be provided in the wearable electronic device (400) of the preceding embodiment. For example, the embodiment(s) of the present disclosure are not limited to the configurations illustrated in the drawings, and additional embodiments may be implemented by selectively combining the configurations disclosed through embodiments of different drawings. In examining the present embodiment, the same reference numbers in the drawings may be given to or omitted for configurations that can be easily understood through the preceding embodiments, and a detailed description thereof may also be omitted.

[0101] Referring to FIGS. 9 and 10, the driving unit (503) may include a guide rail (533) extending in one direction and a slider (531). For example, the slider (531) may be disposed on the guide rail (533) and may reciprocate along the direction in which the guide rail (533) extends. Here, the 'direction in which the guide rail (533) extends' may be substantially parallel to the direction in which at least one of the lenses (411L, 411R, 413L, 413R) (e.g., the second lens (413L, 413R)) advances and retreats. In one embodiment, a user may directly manipulate the slider (531) to move it. For example, the slider (531) may function as an adjustment knob, in which case, even if the driving unit (503) is not operating, the user can directly move at least one of the lenses (411L, 411R, 413L, 413R) using the slider (531). In one embodiment, the slider (531) and the structure guiding the movement of the slider (531) may be provided with gears (433, 435)(s) of FIG. 8. When gears are provided in the guiding structure for the slider (531), the ratio of the movement distance of at least one of the lenses (411L, 411R, 413L, 413R) to the movement distance of the slider (531) may be implemented in various ways depending on the gear ratio. In one embodiment, the travel distance of at least one of the lenses (411L, 411R, 413L, 413R) may be substantially equal to or proportional to the travel distance of the slider (531).

[0102] In one embodiment, the detection unit (504) can detect the current position or movement distance of the slider (531). Here, the 'current position' or 'movement distance' may refer to the position or movement distance of a lens (e.g., the second lens (413L, 413R)) that moves forward and backward, and may be understood as a relative position with respect to a designated point (e.g., the position of the first lens (411L, 411R)) on the wearable electronic device (500) or a distance from the designated point. In one embodiment, the detection unit (504) may include a piezoelectric element (541) connected to the slider (531). For example, the piezoelectric element (541) may detect the movement distance or position of the slider (531) by generating a voltage based on pressure or tension applied according to the movement of the slider (531). The wearable electronic device (500) or processor (420) may store data related to a movement distance corresponding to the magnitude of the voltage generated by the piezoelectric element (541), and may determine the movement distance of the slider (541) and / or the second lens (413L, 413R) based on the voltage generated by the detection unit (504) (e.g., the piezoelectric element (541)).

[0103] According to one embodiment, the wearable electronic device (500) may include electrical wiring (429) (e.g., a flexible printed circuit board) provided between the processor (420) and the detection unit (504). Although not shown, the wearable electronic device (500) may include an input unit (e.g., the input unit (402) of FIG. 5) and / or a driving unit (e.g., the driving unit (403) of FIG. 7), in which case the processor (420) may be electrically connected to the input unit and / or the driving unit via the electrical wiring (429).

[0104] According to one embodiment, in a structure in which a user (U) directly moves a slider (531) or a second lens (413L, 413R), the driving unit (503) may not be electrically connected to the processor (420). In one embodiment, in a structure in which a user (U) directly moves a slider (531) or a second lens (413L, 413R), the slider (531) may function as a driving structure that moves the second lens (413L, 413R) while being an input unit (e.g., input unit (402) of FIG. 5) substantially operated by the user (U).

[0105] According to one embodiment, the processor (420) may receive a voltage generated from the detection unit (504) (e.g., piezoelectric element (541)) through electrodes (534) provided as part of the electrical wiring (429) and / or part of the detection unit (504), and may calculate or confirm a movement distance of the slider (531) and / or the second lens (413L, 413R) based on the received voltage. The processor (420) may provide the user with adjustment result information based on the calculated value.

[0106] According to one embodiment, the display (421) may be disposed inside the housing (410) and may output visual information in a direction toward the user's eyes (E). The lenses (411L, 411R, 413L, 413R) may be substantially disposed between the display (421) and the user's eyes (E). For example, the visual information output from the display (421) may be focused or guided through the lenses (411L, 411R, 413L, 413R) and provided to the user's eyes (E). In one embodiment, the refractive power of the lens assembly (401L, 401R) can be adjusted by moving at least one of the lenses (411L, 411R, 413L, 413R) (e.g., the second lens (413L, 413R)) forward and backward in one direction between the display (421) and the user's eye (E), and the user (U) can adjust the refractive power of the lens assembly (401L, 401R) to a degree suitable for his or her eyesight by manipulating an input unit (e.g., a slider).

[0107] According to one embodiment, the processor (420) may output information about the movement distance of the lenses (411L, 411R, 413L, 413R)(s) based on a user input, and adjustment result information corresponding to the current position of the lenses (411L, 411R, 413L, 413R)(s). In one embodiment, the adjustment result information may include information about the refractive power of the lens assembly (401L, 401R) and may be provided in the form of sound or in a visual form through the display (421). In one embodiment, the adjustment result information may be in a visual form, such as a number or a shape of a specified shape. For example, the shape provided as the adjustment result information may include a reference design used for measuring vision. By being provided with this adjustment result information, the user (U) can determine whether the position of the lens (411L, 411R, 413L, 413R)(s) is suitable for his / her eyesight.

[0108] FIG. 11 is a flowchart for explaining an operation method (600) of a wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic devices (200, 300, 400, 500) of FIGS. 2 to 7, and / or FIG. 9) according to one embodiment of the present disclosure.

[0109] In examining the operating method (600) according to the embodiment(s) of the present disclosure, the configuration of the electronic device and / or wearable electronic device described above may be referred to.

[0110] Referring to FIG. 11, the operating method (600) of the wearable electronic device (400, 500) may include operation 601 of detecting an input, operation 602 of driving a driving unit (403, 503) and / or moving a lens (411L, 411R, 413L, 413R)(s), operation 603 of checking (or calculating) a moving distance or refractive power, and / or operation 604 of outputting information about the checked moving distance or refractive power. In one embodiment, in the wearable electronic device (500) of FIG. 9 and / or FIG. 10, operations 601 and 602 may be understood as operations in which a user directly moves a slider (531) or a second lens (413L, 413R). In one embodiment, when performing operation 603, the method (600) of operating the wearable electronic device (400, 500) may further include operation 625 of detecting movement of the lenses (411L, 411R, 413L, 413R). For example, operation 625 may be performed when the wearable electronic device (400, 500) includes a detection unit (504) as in the embodiments of FIGS. 9 and / or 10. For example, the wearable electronic device (400) of FIGS. 7 and / or 8 may further include the detection unit (504) of FIGS. 9 and / or 10 to implement an additional embodiment.

[0111] According to one embodiment, in operation 601, the wearable electronic device (400, 500) and / or the processor (120, 420) may detect a user input using an input unit (402) (e.g., a key, a touch sensor, and / or a piezoelectric element). When the wearable electronic device (400, 500) is worn on the body of the user (U), the direction or pressure of the user input detected by the input unit (402) may vary. The wearable electronic device (400, 500) and / or the processor (420) may generate a control signal based on an input in a direction substantially parallel to a movement direction of the lens (411L, 411R, 413L, 413R)(s) among user inputs in various directions. For example, operation 602 may be executed when the user input detected in operation 601 is determined to be in a direction substantially parallel to the direction of movement of the lenses (411L, 411R, 413L, 413R).

[0112] According to one embodiment, in operation 602, the wearable electronic device (400, 500) and / or the processor (420) can control the driving unit (403) (e.g., the driving motor (431)) to move the lenses (411L, 411R, 413L, 413R)(s). For example, according to the operation of the driving motor (431), the first gear (433) (e.g., the pinion gear) of FIG. 8 can rotate and move linearly on the second gear (435) (e.g., the rack gear). As a result, the lens (411L, 411R, 413L, 413R)(s) (e.g., the second lens (413L, 413R)) can move between the display (421) and the user's eye (E), and the lens assembly (401L, 401R) can provide a refractive power suitable for the user's eyesight. In one embodiment, the second lens (413L, 413R) may be disposed on the slider (531), as in the wearable electronic device (500) of FIGS. 9 and / or 10 , in which case, operations 601 and / or 602 may be implemented substantially by the user (U) directly moving the slider (531). For example, in the wearable electronic device (500) of FIGS. 9 and / or 10 , the processor (420) may not perform operations 601 and / or 602.

[0113] According to one embodiment, in operation 603, the wearable electronic device (400, 500) and / or the processor (420) may check (or calculate) the movement distance of the lenses (411L, 411R, 413L, 413R)(s) or the refractive power of the lens assembly (401L, 401R). For example, operation 603 may be an operation in which the processor (420) calculates (or checks) a result value of controlling the driving unit (403) based on the length, direction, and / or pressure of the user input detected in the input unit (402) of FIG. 5 (e.g., a value related to the movement distance or the refractive power). When the wearable electronic device (400, 500) includes a detection unit (e.g., detection unit (504) of FIG. 9) and the processor (420) does not perform operation 601 and / or operation 602, in operation 603, the processor (420) can check or calculate the movement distance of the lens (411L, 411R, 413L, 413R)(s) or the refractive power of the lens assembly (401L, 401R) based on the voltage generated in the detection unit (504) (e.g., piezoelectric element (541)).

[0114] According to one embodiment, in operation 604, the wearable electronic device (400, 500) and / or the processor (420) may provide the user with information regarding the result value calculated in operation 603. In one embodiment, the processor (420) may provide the user with information regarding the result value in an auditory or visual form. In the illustrated embodiment, a configuration for providing information regarding the result value in a visual form may be exemplified. For example, the information regarding the result value may be output in a visual form, such as a number or a shape of a specified shape, through the display (421). For example, the number representing the information regarding the result value may exemplify the position or movement distance of the current lens (411L, 411R, 413L, 413R)(s). In one embodiment, the shape representing the information regarding the result value may be implemented in a form, such as a target, concentric circles, a character, and / or a photograph. In one embodiment, the visual information provided to the user (U) may include a reference design used for visual acuity measurement. While receiving this visual information, the user (U) can adjust the position of the lens (411L, 411R, 413L, 413R)(s) to a position that matches his / her visual acuity. In this way, the wearable electronic device (101, 200, 300, 400, 500) according to the embodiment(s) of the present disclosure can provide visual information that allows the user (U) to easily recognize the focus adjustment state while adjusting the focus, thereby enhancing convenience in focus adjustment.

[0115] As described above, the wearable electronic device according to the embodiment(s) of the present disclosure (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200, 300, 400, 500) of FIGS. 2 to 7, and / or 9) can be easily adjusted to a state having a refractive power suitable for the user. For example, the use state can be conveniently adjusted by using an input unit (e.g., the input unit (402) of FIG. 5) provided on the wearing member (e.g., the wearing member (202a, 202b, 402a, 402b) of FIG. 2 or FIG. 5), and the user's operation direction and the movement direction of the lens (e.g., the lens (411L, 411R, 413L, 413R)(s) of FIGS. 5 to 7) are substantially synchronized, so that the user can intuitively recognize the adjustment state. In one embodiment, user accessibility is improved in terms of the arrangement and structure of the input unit and / or the driving unit (e.g., the driving unit (403, 503) of FIGS. 7 to 10) for controlling the use state, thereby making it convenient to wear or use while wearing.
