[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 674,061, filed July 22, 2024, entitled “FACIAL INTERFACE FOR ELECTRONICDEVICE”, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The described embodiments generally relate to wearable electronic devices. More specifically, embodiments of the present invention relate to head-mounted display devices and methods for face bonding thereof. Background Technology

[0004] Recent advancements in portable computing have spurred increased use of head-mounted devices. For extended use, comfort is a key factor in user adoption of head-mounted devices. A crucial component affecting comfort is the face mount, which rests against the user's face and transmits the weight of the head-mounted device. Current face mounts for head-mounted devices are typically molded to a standard size and have limited adjustability, resulting in pressure points and discomfort for users with different facial features and head shapes. The adjustability of current head-mounted devices does not fully address the problems of pressure points and discomfort. Therefore, there is a need in the art for an adjustable face mount that can comfortably conform to a wider range of facial shapes and sizes while remaining stable during use. This would improve user comfort and broaden the potential user base for head-mounted devices. Summary of the Invention

[0005] In at least one example of this disclosure, a face mount for a head-mounted display device may include a first frame. In some examples, the face mount further includes a second frame. In some examples, the face mount further includes a linear actuator movably coupled to the first frame and the second frame. In some examples, the face mount further includes a plate movably fastened to the second frame, wherein the linear actuator is coupled to the first frame at a first end and defines a spherical portion at a second end opposite the first end, and the face mount may also include a slot configured to receive the spherical portion of the linear actuator. In some examples, the face mount may also include a second frame that is more flexible than the first frame.

[0024] Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a single preferred embodiment. Rather, it is intended to cover alternatives, modifications, and equivalents that may be included within the substance and scope of the described embodiments as defined by the appended claims.

[0025] The following disclosure relates to display components and facial connectors for head-mounted display devices. Current facial connectors for head-mounted devices are typically molded to a universal size and have limited adjustability, resulting in pressure points and discomfort for users with different facial features and head shapes. The adjustability of current head-mounted devices does not fully address the problems of pressure points and discomfort. Therefore, the devices and systems described herein for head-mounted devices include adjustable facial connectors that comfortably conform to a wide range of facial shapes and sizes while remaining stable during use. The devices, systems, and methods of this disclosure improve user comfort and broaden the potential user base for head-mounted devices.

[0026] To achieve these and other advantages, in some examples, the face connector may include one or more frames coupled together via one or more linear actuators. At least one frame may rest against the user's face during use, and the linear actuators may control the distance between the one or more frames. The face connector may include a window configured to display content to the user. The window may be positioned within or secured to the frame and may define an exit pupil distance. The linear actuators may achieve this exit pupil distance by changing the distance between the one or more frames. In some examples, the linear actuators may be movably coupled to one or more frames. The linear actuators may be driven independently or uniformly to change the distance between the one or more frames or the angle between the one or more frames. The translational and rotational adjustability between the frames via the linear actuators allows the face connector to conform to a wide variety of user facial features and head shapes.

[0027] In some examples, the linear actuator may extend from one frame to a second frame. The linear actuator may be fixed to the first frame and coupled to the second frame via one or more plates. These one or more plates may be coupled to the second frame and may each define a slot. In some examples, the linear actuator may each include a piston. Each piston may define a spherical portion at one end. The slot of each plate may be configured to receive the spherical portion. In some examples, the spherical portion of each piston may be displaced along the slot of the corresponding plate. The spherical portion may also rotate relative to the plate about at least one axis. In some examples, at least one of these plates may be translatably coupled to the second frame in at least one direction. The translatable and rotatable nature of the coupling between the linear actuator and the second frame allows any number of pistons to extend or retract, thereby causing the second frame to translate or rotate relative to the first frame. Translation and / or rotation of the second frame relative to the first frame can alter the characteristics of the facial engagement, thereby promoting a comfortable and personalized user experience.

[0028] In some examples, the second frame may be more flexible than the first frame. A flexible second frame can improve the comfort of the facial engagement. In some examples, the user's face can deform the second frame, thereby altering the geometry between the second frame and the movable coupling. In some examples, deformation of the second frame can result in a longer arc length between two or more linear actuators. In this case, each spherical portion of each linear actuator can slide along a slot defined by each plate, allowing the second frame to deform without inducing shear stress or strain on the linear actuators.

[0029] In some examples, the linear actuator can be driven in response to user input. The user can interact with an input device included in the face mount or with a user interface displayed in a window. Driving the linear actuator in response to user input allows the user to customize the fit of the face mount, thus promoting a pleasant user experience and enabling the user to wear the face mount for longer periods or perform more tasks compared to other devices. In some examples, the face mount may include one or more sensors configured to collect data. This data can be interpreted by a processor, and the linear actuator can be driven in response to this data. In some examples, data can be collected once, and the face mount can be adjusted in response to the selection of a user profile. In other examples, the one or more sensors can continuously collect data to drive the linear actuator in a feedback loop. In some examples, the face mount may include two, three, four, five, six, or more linear actuators. The number of linear actuators can be optimized for comfort, processor requirements, energy usage, or other parameters. In some examples, the linear actuator can change the shape of one or more face joints to form a light seal between the user's face and the face joint.

[0030] Please refer to Figures 1 to 2 below. Figure 7B These embodiments and other embodiments are discussed. However, those skilled in the art will readily understand that the detailed descriptions given herein with respect to the accompanying drawings are for illustrative purposes only and should not be construed as limiting. Furthermore, as used herein, a system, method, article, component, feature, or sub-feature including at least one of the first, second, or third options should be understood to refer to a system, method, article, component, feature, or sub-feature that may include one option of each listed option (e.g., only one first option, only one second option, only one third option), multiple options of a single listed option (e.g., two or more first options), two options simultaneously (e.g., one first option and one second option), or combinations thereof (e.g., two first options and one second option).

[0031] Figures 1A to 1BA head-mounted device 100 is shown. The head-mounted display device 100 can be configured to be mounted on a user's head and display visual media to the user. In some examples, the visual media displayed by the head-mounted display device 100 may include video, live streaming, websites, recordings, virtual reality scenes, television, or other forms of visual media. The head-mounted display device 100 may include a fastening strap 102. The head-mounted display device 100 may also include a face mount 104 configured to rest on a user's face. In some examples, the face mount 104 may be a display component. The face mount 104 may be coupled to the fastening strap 102 such that the head-mounted display device 100 is secured to the user's head during use. In some examples, the face mount 104 may include a first frame 106 and a second frame 108. The face mount 104 may also include a window 110 and a light source 112 configured to generate content displayed at the window 110. In some examples, the content generated by the light source 112 and displayed at the window 110 may be visual media.

[0032] In some examples, the light seal may include a second frame 108. When a user wears the head-mounted display device 100, the light seal reduces or prevents light from entering the user's field of view. By preventing light from entering the user's field of view, the light seal reduces or eliminates external distractions that may distract the user or disrupt the user experience. In some examples, the light seal can help improve the user's viewing experience by blocking external light sources and allowing the user to immerse themselves in the content displayed at the window. In some examples, the second frame 108 may be at least partially transparent. A partially transparent second frame 108 allows the user to perceive objects or people near or adjacent to the user. For example, a partially transparent second frame 108 allows the user to move through space while avoiding objects and people. In some examples, the head-mounted display device 100 may be configured to display a live stream of the user's environment and display visual media overlaid on the live stream. The partially transparent second frame 108 minimizes the portion of the user's field of view occupied by the second frame 108.

Similarly, any of the features, components, and / or parts shown and described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown and / or configurations. Figures 1A to 1B Examples of devices, features, components, and parts are shown below. (Refer to the following...) Figure 2 Examples of adjustable face joints, movable couplings, and linear actuators are given.

[0034] Figure 2An example of a facial connector 200 is shown. The facial connector 200 may be adjustable and conformable to a user's face. In some examples, the facial connector 200 may be configured to conform to the contours of a user's face and help facilitate a comfortable user experience. The facial connector 200 may include a first frame 208, a second frame 206, and one or more linear actuators 214a-214b, 222a-222b. The first frame 206 and the second frame 208 may include support features 230a-230b. The support features 230a-230b may be configured to rest on the user's nose or bridge of the nose and support at least a portion of the weight of the facial connector 200. The support features 230a-230b may also be configured to form a light seal around the user's nose. In some examples, one or more linear actuators 214a-214b, 222a-222b may movably connect the first frame 208 to the second frame 206. Each of one or more linear actuators 214a-214b, 222a-222b may be coupled to the first frame 208 at a first end. Linear actuators 214a-214b may define spherical portions 232a-232b at a second end opposite to the first end, and linear actuators 222a-222b may define spherical portions 234a-234b (234b not shown) at a second end opposite to the first end. In some examples, one or more linear actuators 214a-214b, 222a-222b may be fixedly fastened to the first frame 208. The face joint 200 may also include one or more plates 218a-218b and one or more plates 226a-226b. In some examples, at least one of plates 218a-218b, 226a-226b may be movably fastened to the second frame 208. Plates 218a-218b may include slots 220a-220b configured to receive corresponding spherical portions 232a-232b, and plates 226a-226b may include slots 228a-228b configured to receive corresponding spherical portions 234a-234b.

[0035] In some examples, linear actuators 214a-214b, 222a-222b may be regulating motors. One or more of linear actuators 214a-214b, 222a-222b may be configured to define the distance between the first frame 206 and the second frame 208. At least one of linear actuators 214a-214b, 222a-222b may be configured to change the distance between the first frame 206 and the second frame 208. Linear actuators 214a-214b, 222a-222b may include pistons 216a-216b, 224a-224b defining spherical portions 232a-232b, 234a-234b accommodated by plates 218a-218b, 226a-226b. Pistons 216a-216b and 224a-224b can extend or retract from the first frame 206, thereby changing the distance between the first frame 206 and the second frame 208. In some examples, the second frame 208 can be configured to be adjacent to the user's face, and the distance between the first frame 206 and the second frame 208 can affect the exit pupil distance between the user's eyes and the first frame 206. In some examples, the first frame 206 may include a window configured to display content to the user, similar to the reference [reference]. Figure 1B The described second frame 108 includes a window 110. The exit pupil distance between the first frame 206 and the user's eyes can affect the user experience, the quality of the displayed content, or the amount of time the user can comfortably use the face connector 200. Therefore, at least one linear actuator 214a-214b, 222a-222b that defines the distance between the first frame 206 and the second frame 208 can help improve the quality of the content perceived by the user, enabling the user to use the face connector 200 for a longer period of time and promoting a more comfortable user experience overall.

[0036] In some examples, the spherical portions 232a-232b, 234a-234b and plates 218a-218b, 226a-226b can form a movable coupling. When one or more of the linear actuators 214a-214b, 222a-222b change the distance between the first frame 206 and the second frame 208, the movable coupling defined by 232a and 218a, 232b and 218b, 234a and 226a, and 234b and 226b allows the second frame 208 to translate, rotate, or otherwise displace relative to the first frame 206. The movable coupling can define various degrees of freedom between the spherical portions 232a-232b, 234a-234b and the second frame 208. In some examples, the movable coupling may define five degrees of freedom between the spherical portions 232a-232b, 234a-234b and the second frame 208. The degrees of freedom defined by the movable coupling may include translation in two directions along the exterior of the second frame 208. The degrees of freedom defined by the movable coupling may also include rotation in the form of pitch, roll, and yaw of the spherical portions 232a-232b, 234a-234b. In some examples, plates 218a-218b and plates 226a-226b may have different degrees of freedom. For example, plates 218a-218b may be movably secured to the second frame 208, and plate 226-b may be fixedly secured to the second frame 208.

[0037] In some examples, the second frame 208 may be more flexible than the first frame 206. A more flexible second frame 208 can conform to the contours of various user head shapes and facial features. A second frame 208 conforming to various head shapes and facial features can provide a comfortable user experience for as many people as possible. Additionally, a more flexible second frame 208 can allow the second frame 208 to form a light seal around the user's eyes, resulting in an attractive user experience. In some cases, deformation of the flexible second frame 208 may alter one or more geometric properties of the connection between the first frame 206 and the second frame 208. The aforementioned movable coupling allows for changes in the geometric relationship between the first frame 206 and the second frame 208 when the second frame 208 deforms and the distance between the first frame 206 and the second frame 208 changes. In some examples, the spherical portions 232a-232b, 234a-234b may be displaced along a line or arc defined by slots 220a-220b, 228a-228b. For example, spherical portion 232a may be displaced along the length of slot 220a. Spherical portions 232a-232b, 234a-234b may also be rotated relative to plates 218a-218b, 226a-226b. In some examples, at least one of plates 218a-218b, 226a-226b may be able to translate relative to the second frame 208 in a first direction, and at least one of slots 220a-220b, 228a-228b may extend in a second direction different from the first direction.

[0038] Figure 2 Any of the features, components, and / or parts shown (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown in the other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown or described herein. Figure 2 Examples of devices, features, components, and parts are shown.

[0039] Figures 3A to 3CA side view of a display assembly 300 in several different positions is shown. In some examples, the display assembly 300 may be used in a head-mounted display device. The display assembly 300 may be adjustable, and its different positions may be adapted or conformal to various user head shapes and facial features. The adjustability of the display assembly 300 promotes a comfortable and desired user experience. The display assembly 300 may include a frame 306, a face mount 308, and a display 310 coupled to the frame 306. The display 310 may be a window that can be configured to display content to a user. The face mount 308 may be coupled to the frame 306 via one or more linear motors 314, 322. The linear motor 314 may be a first linear actuator, and the linear motor 322 may be a second linear actuator. In some examples, the display 310 may be positioned between the linear motors 314 and 322. The linear motors 314 and 322 may each include pistons 316 and 324, respectively. Each piston 316, 324 may extend between the frame 306 and the face connector 308. Each piston 316, 324 may also define spherical portions 332, 334, respectively. The display assembly 300 may include one or more attachment plates 318, 326. Each attachment plate 318, 326 may define slots 320, 324 configured to receive the spherical portions 332, 334. In some examples, a linear motor 314 may be secured to the frame 306, a piston 316 may extend from the frame 306 to the face connector 308, an attachment plate 318 may be secured to the face connector 308, and a slot 320 may be configured to receive the spherical portion 332. Similarly, a linear motor 322 may be secured to the frame 306, a piston 324 may extend from the frame 306 to the face connector 308, an attachment plate 326 may be secured to the face connector 308, and a slot 328 may be configured to receive the spherical portion 334.

[0040] In some examples, linear motors 314, 322 may include a first end coupled to frame 306 and a second end coupled to face connector 308. The first end of linear motors 314, 322 may be fixedly coupled to frame 306. The second end may be translatably coupled to face connector 308. Linear motors 314, 322 may include attachment plates 318, 326. In some examples, each attachment plate 318, 326 may define an attachment point between linear motors 314, 322 and face connector 308. For example, attachment plate 318 may define a first attachment point, and attachment plate 326 may define a second attachment point. In other examples, any or both of linear motors 314, 322 may define a spherical portion 332 or 334, and the first attachment point may define a slot 320 or 328 configured to receive the spherical portion 332 or 334.

[0041] Each linear motor 314, 322 may be coupled to the face joint 308 at an attachment point that is translatable relative to the face joint 308 in a first and a second direction. For example, at least one of the attachment plates 318, 326 may be translatable relative to the face joint 308 in the first and a second direction. In some examples, attachment plate 326 is fixedly fastened to the face joint 308, and attachment plate 318 is translatable relative to the face joint 308. Translation of at least one attachment plate 318, 326 may allow the face joint 308 to tilt relative to the frame 306 without changing the angle of the linear motors 314, 322. Attachment plates 318, 326 and spherical portions 332, 334 may also form a spherical joint. In some examples, linear motors 318, 322 may be fixed to the frame 306, and each linear motor 314, 322 may include a spherical joint rotatably fastened to the face joint 308. In some examples, linear motor 314 may be a first adjusting motor, and linear motor 322 may be a second adjusting motor. Linear motors 314 and 322 may be configured to extend or retract to change the distance between frame 306 and face joint 308. Linear motor 314 may extend from frame 306 to the face joint, and linear motor 322 may extend from frame 306 to the face joint 308. In some examples, display 310 may be disposed between linear motors 314 and 322.

[0042] Figure 3A The display assembly 300 is shown in a first position. In this first position, linear motors 314 and 322 may define a first distance between the frame 306 and the face mount 308. In some examples, the face mount 308 may be configured to be adjacent to a user's face, and the distance between the first frame 306 and the face mount 308 may affect the exit pupil distance between the user's eyes and the first frame 306. This exit pupil distance may be the distance between the user's eyes and the display 310. The face mount 308 may be adjacent to the user's face, and the display 310 may be secured to the frame 306. Therefore, the distance between the frame 306 and the face mount 308 may affect the exit pupil distance. This exit pupil distance may affect the user experience, the quality of the displayed content, or the amount of time the user can comfortably use the display assembly 300. Figure 3C The display assembly 300 is shown in a third position, where linear motors 314 and 322 extend further from the frame 306 relative to the first position. In some examples, Figure 3C The display assembly 300 shown can define different exit pupil distances between the display 310 and the user's eyes. In some examples, different distances between the frame 306 and the face mount 308 can facilitate clear image perception for users who typically require corrective lenses. Figure 3A and Figure 3CIn this configuration, linear motors 314 and 322 can extend or retract in a consistent manner.

[0043] Figure 3B The display assembly 300 is shown in a second position. In this second position, one linear motor may extend further from the frame 306 than the other. For example, linear motor 314 may extend further than linear motor 322. In this second position, linear motors 314 and 322 can be actuated independently of each other. The fact that linear motor 314 extends further from the frame 306 relative to linear motor 322 allows the face mount 308 to be tilted relative to the frame 306. Tilting the face mount 308 relative to the frame 306 allows it to abut various user faces with different facial features. For example, tilting the top of the face mount 308 away from the frame 306 by extending linear motor 314 further from the frame 306 relative to linear motor 322 better accommodates users whose nose or bridge of the nose is further forward than their forehead. In other examples, tilting the bottom of the face connector 308 away from the frame 306 by extending the linear motor 322 further from the frame 306 relative to the linear motor 314 can better accommodate users whose foreheads are further forward than their noses or bridges of the nose.

[0044] When the face joint 308 tilts relative to the frame 306 in response to different extensions of the linear motors 314, 322, the spherical portions 332, 334 can rotate within the slots 320, 328. Additionally, at least one of the plates 318, 326 can translate along the exterior of the face joint 308. Extension or retraction of one or both of the linear motors 314, 322 can change the distance between the spherical portions 332, 334. Translation of at least one of the plates 318, 326 allows the pistons 316, 324 to extend axially without rotating relative to the frame 306, while still changing the distance between the spherical portions 332, 334 fastened to the face joint 308 via the plates 318, 326. For example, as... Figure 3B As shown, when piston 316 extends further from frame 306 than piston 324, plate 318 can translate relative to face mount 308 toward plate 326. In another position, when piston 324 extends further from frame 306 than piston 316, plate 318 can translate relative to face mount 308 away from plate 326. Display assembly 300 can be configured to occupy Figures 3A to 3C Any position between the first, second, and third positions shown. The display component 300 can also be configured to occupy... Figures 3A to 3C The location is not shown in the image.

[0045] In some examples, at least one of the linear motors 314 and 322 may be configured to be driven in response to input from a user. In some examples, user input may be collected from a user interface. For example, a user may interact with information generated at display 310 to drive linear motors 314 and 322, thereby adjusting the position and / or fit of the face mount 308. In other examples, display assembly 300 may include at least one input device 348. Input device 348 may be a button, switch, lever, or another input device. In some examples, input device 348 may be electrically coupled to linear motor 314, wherein manipulation of input device 348 may cause linear motor 314 to change the distance between frame 3086 and face mount 308.

[0046] For example, a user can press the input device 348, which actuates the linear motors 314 and 322 in response to the press. Adjusting the face mount 308 in response to user input via actuation of the linear motors 314 and 322 allows the user to customize the fit of the display assembly 300. Customization of the fit of the display assembly 300 promotes a desired user experience, enhances the comfort of the display assembly 300, and allows the user to use the display assembly for longer periods.

[0047] In other examples, at least one of the linear motors 314 and 322 may be configured to automatically adjust the face mount 308 relative to the frame 306. In some examples, the display component 310 may include a sensor 344 and a processor 346. The sensor 344 may be configured to collect data, and the processor 346 may be electrically coupled to the sensor 344, linear motor 314, and linear motor 322. The processor 346 may be configured to drive the linear motors 314 and 322 in response to the data. In some examples, the sensor 344 may be a distance sensor configured to measure the distance between the frame 306 and the user's face. The linear motors 314 and 322 may be configured to be driven such that the sensor 344 measures the desired distance. In other examples, the sensor 344 may be a camera configured to scan the user's face to measure facial features. The linear motors 314 and 322 may be configured to be driven in response to the facial features collected by the sensor 344. In other examples, sensor 344 may measure the force exerted on display component 300 by the user's face when the user wears display component 300. Linear motors 314, 322 may be configured to be driven in response to the force measured by sensor 344, such that the force exerted on display component 300 by the user's head remains within the range of force.

[0048] In some examples, linear actuators 314 and 322 may form a feedback loop with sensor 344. In this way, display component 300 can continuously adjust linear motors 314 and 322 in response to different users, different user activities, different user facial expressions, or other conditions. In other examples, sensor 344 may measure and store the user's face during the setup process. Display component 300 may store data from multiple users, and various data can be used to drive linear motors 314 and 322 in response to a corresponding user profile. This user profile may be selected via display 310, or display component 300 may detect nearby devices and automatically select a user profile. In other examples, sensor 344 may visually detect the user's face and automatically adjust the face mount via linear motors 314 and 322 based on stored data. In still other examples, display device 300 may adjust linear motors 314 and 322 based on data from sensor 344 whenever the user puts on or takes off display component 300.

Similarly, any of the features, components, and / or parts shown or described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown or described herein. Figures 3A to 3C Examples of devices, features, components, and parts are shown. More examples of display assemblies including linear motors and faceplate connectors are given below.

[0050] Figure 4A side view of another example of a display assembly 400 is shown. The display assembly 400 may include a frame 406, a face mount 408, and linear motors 414, 422 that attach the face mount 408 to the frame 406. The display assembly 400 may be worn on a user's face or head, and the face mount 408 may be configured to comfortably fit the user's face. The linear motor 414 may include a piston 416 and a plate 418. The linear motor 422 may include a piston 424 and a plate 426. In some examples, pistons 416, 424 may be fixedly coupled to corresponding plates 418, 426. At least one of the linear motors 414, 422 may be movably coupled to the frame 406, and plates 418, 426 may be translatably coupled to the face mount 408. The combination of the rotatable connection of linear motors 414, 422 to frame 406 and the translational connection of plates 418, 426 allows the face mount 408 to translate, rotate, or otherwise displace relative to frame 406. This translation, rotation, or other displacement of the face mount 408 relative to frame 406 allows the display assembly 400 to adjust and comfortably fit various user facial shapes.

Similarly, any of the features, components, and / or parts shown or described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown or described herein. Figure 4 Examples of devices, features, components, and parts are shown below. (Refer to the following...) Figures 5A to 5B More examples of adjustable display components are provided.

[0052] Figures 5A to 5BA top view of the display assembly 500 in both a demounted and a worn state is shown. The display assembly 500 may include a frame 506, a face connector 508, and one or more linear motors 514a-514b. The linear motors 514a-514b may be at least partially disposed within the frame 506. In some examples, the linear motors 514a-514b may be fastened to the frame 506. Each of the linear motors 514a-514b may include pistons 516a-516b. Each piston 516a-516b may define a rounded end 532a-532b. The display assembly 500 may include one or more plates 518a-518b. In some examples, each plate 518a-518b may define a slot 520a-520b configured to receive a corresponding rounded end 532a-532b. In this way, the face connector 508 can be coupled to the frame 506 via linear motors 514a-514b and plates 518a-518b. In some examples, the face connector 508 may be more flexible than the frame 506, thereby allowing the face connector 508 to conform to the user's head or face.

[0053] Figure 5A The display assembly 500 is shown in a detached state. In the detached state, the facial connector 508 can retain its original shape. For example, the facial connector 508 can be manufactured to fit various facial structures, and the manufactured shape can be maintained in the detached state. In some examples, Figures 5A to 5B Each of the linear motors 314a-314b shown can be configured to be actuated independently. Independent actuation of the linear motors 514a-514b allows the face connector 508 to tilt, rotate, or twist relative to the frame 506. By tilting, rotating, or twisting relative to the frame 506, the face connector 508 can be configured to adapt to various facial features and user head shapes. In other examples, Figures 5A to 5B The linear motors 314a-314b shown can be configured to actuate uniformly. Uniform actuation of the linear motors 514a-514b can change the distance between the frame 506 and the face joint 508 without causing the face joint 508 to tilt, rotate, or twist relative to the frame 506. In some examples, uniform actuation of the linear motors 514a-514b can reduce the energy or processing requirements of the linear motors 514a-514b. In some examples, the linear motors 514a-514b can be configured to actuate independently under certain conditions and uniformly under other conditions.

[0054] Figure 5BA display assembly 500 in a worn state is shown. In the worn state, a user's head 536 can exert force on a face connector 508, causing the face connector 508 to bend, flex, or otherwise deform. This deformation of the face connector 508 allows it to form a seal between the display assembly 500 and the user's head 536. The seal formed between the face connector 508 and the user's head 536 prevents light from entering the user's field of vision, prevents foreign contaminants such as dirt or dust from entering the user's eyes, and distributes any force experienced by the user over the largest possible area. In some examples, the deformation of the face connector 508 can promote a comfortable and desired user experience. For example, a soft, flexible face connector 508 can minimize localized forces on the head 536 and reduce fatigue caused by wearing the display assembly 500.

[0055] exist Figure 5A In the detached state shown, the circular ends 532a-532b can be centrally positioned within the slots 520a-520b. Figure 5B In the worn state shown, the circular ends 532a-532b can be displaced relative to their placement within the slots 520a-520b in the unworn state. When the head 536 bends or otherwise deforms the face connector 508, the distance between the circular ends 532a-532b remains constant, while the arc length of the face connector 508 between the circular ends 532a-532b can increase. To compensate for the increased length of the face connector 508 positioned between the circular ends 532a-532b, each circular end 532a, 532b can slide or displace along its corresponding slot 520a, 520b. By allowing the circular ends 523a-523b to displace within the slots 520a-520b, the plates 518a-518b allow the face connector 508 to flex, bend, or otherwise conform to different head shapes or facial structures. In this way, display component 500 can promote a comfortable user experience.

[0056] Figures 5A to 5B Any of the features, components, and / or parts shown (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown in the other figures described herein. Similarly, any of the features, components, and / or parts shown and described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown and / or configurations. Figures 5A to 5B Examples of devices, features, components, and parts are shown.

[0057] Figures 6A to 6CA face connector 600 is shown, comprising a frame 608 with different attachment points 638a-638f. In some examples, a linear actuator may be fastened to each attachment point 638a-638f. In use, the face connector 600 may be placed adjacent to a user's face. Different configurations of attachment points 638a-638f can affect the comfort characteristics of the face connector 600. Figure 6A A frame 608 including attachment points 638a-638c is shown. Attachment point 638a may be positioned where the frame 608 can contact the user's forehead when the face connector 600 is in use. Attachment points 628b-628c may be positioned where the frame 608 can contact the user's cheek. In some examples, attachment points 638a-638b may be located above the user's maxilla or cheekbone when the face connector 600 is in use. In some examples, using only one attachment point 638a located where the frame 608 can be adjacent to the user's forehead simplifies adjustments to the face connector via a linear actuator while allowing the frame 608 to rotate about an axis defined by attachment points 638b-638c.

[0058] Figure 6B A frame 608 including attachment points 638a-638d is shown. In some examples, the frame 608 may include two attachment points 638a-638b positioned where the frame 608 can contact the user's forehead when the face mount 600 is in use. Including two attachment points 638a-638b at the positions where the frame 608 can contact the user's forehead allows the frame 608 to deform between the two attachment points 638a-638b in response to forces applied by the user's forehead, such as... Figure 5B The deformation shown is similar to... Figure 6A The facial connector 600 shown has attachment points 638c-638d that can be located above the user's maxilla or cheekbone when in use. Figure 6C A frame 608 including attachment points 638a-638f is shown. Figure 6CIn this design, additional attachment points 638d-638f can be located at positions where the frame 608 can contact the user's temples. Positioning attachment points 638e-638f at these locations allows the linear actuator to extend further from the frame 608 at the temples than it would at the user's forehead, cheek, or nose. Positioning attachment points 638e-638f also allows the frame 608 to form a more uniform or tighter seal against the user's face. Additionally, including more attachment points 638a-638f reduces the force exerted on the user's face at each attachment point 638a-638f. The face connector 600 may also include more attachment points than 638a-638f, and the positions of attachment points 638a-638f can be varied to optimize comfort.

[0059] Figures 6A to 6C Any of the features, components, and / or parts shown (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown in the other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown or described herein. Figures 6A to 6C Examples of devices, features, components, and parts are shown below. More examples of linear actuators, hinges, and plates are given below.

[0060] Figures 7A to 7B An example of a movable connector 700 is shown. Figure 7A A movable coupling including a linear actuator 714, a piston, a frame 708, and a plate 718 is shown. In some examples, the piston 716 may define a ball 732, and the plate 718 may define a cup 740 configured to receive the ball 732. The ball 732 and the cup 740 may be a spherical joint defining three degrees of freedom (i.e., pitch, roll, and yaw). In some examples, the plate 718 may be capable of translation in two directions relative to the frame 708. The piston 716 may be actuated relative to the frame 708 in a third translational direction. Therefore, Figure 7A The movable connector 700 shown can define or control six degrees of freedom. Any degree of freedom can be changed, modulated, or controlled to optimize the movable connector 700, thereby providing comfort when using the head-mounted display device.

[0061] Figure 7BA movable coupling 700 is shown, comprising a linear actuator 714, a piston 716, a frame 708, and a plate 718. In some examples, the piston may define a cylindrical end 742, and the plate 718 may be configured to receive the cylindrical end 742. In some examples, the cylindrical end 742 may define a single degree of freedom, namely pitch, between the piston 716 and the plate 718. In some examples, the plate 718 may be able to translate relative to the frame 708 in at least one direction and / or be able to rotate relative to the frame 708 in at least one direction. The piston 716 may be actuated relative to the frame 708 in another translational direction. Any degree of freedom defined by the movable coupling 700 may be altered, modulated, or controlled to optimize the movable coupling 700, thereby providing comfort when using a head-mounted display device. Additionally, Figures 7A to 7B The linear actuator 714 of any of the movable couplings 700 shown can be configured to disengage in response to an applied force exceeding a threshold. Disengaging the linear actuator 714 in response to an applied force exceeding a threshold helps protect the device from external forces such as a user's face, a drop, or other forces.

Similarly, any of the features, components, and / or parts shown and described with reference to the other figures (including their arrangement and configuration) may be included, individually or in any combination, in any other example of the devices, features, components, and parts shown and / or configurations.

[0063] Within the limits applicable to the techniques of this invention, the collection and use of data from various sources can be used to improve the delivery of inspirational content or any other content that a user may be interested in. This disclosure contemplates that, in some instances, such collected data may include personal information data that uniquely identifies or can be used to contact or locate specific individuals. Such personal information data may include demographic data, location-based data, telephone numbers, email addresses, etc. (formerly known as) User ID, home address, data or records related to the user's health or health level (e.g., vital sign measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

[0064] This disclosure recognizes that the use of such personal information data in the present invention can benefit users. For example, the personal information data can be used to deliver targeted content that is of interest to the user. Therefore, the use of such personal information data enables users to have planned control over the delivered content. Furthermore, this disclosure also anticipates other uses of personal information data that are beneficial to users. For example, health and fitness data can be used to provide insights into a user's overall health status or can be used as positive feedback for individuals using the technology to pursue health goals.

[0065] This disclosure anticipates that entities responsible for the collection, analysis, disclosure, transmission, storage, or other use of such personal information data will comply with robust privacy policies and / or privacy measures. Specifically, such entities should implement and adhere to privacy policies and measures that are recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy and security of personal information data. Such policies should be easily accessible to users and should be updated as the collection and / or use of data changes. Personal information from users should be collected for legitimate and reasonable entity purposes and should not be shared or sold outside of these legitimate purposes. Furthermore, such collection / sharing should be conducted only after receiving informed consent from users. Additionally, such entities should consider taking any necessary steps to protect and safeguard the right to access such personal information data and ensure that other entities with access to personal information data comply with the privacy policies and procedures of those other entities. Moreover, such entities may subject themselves to third-party assessments to demonstrate their compliance with widely accepted privacy policies and privacy practices. Furthermore, policies and practices should be adapted to the specific types of personal information data collected and / or accessed, and to applicable laws and standards, including considerations of specific jurisdictions. For example, in the United States, the collection or acquisition of certain health data may be governed by federal and / or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); while in other countries, health data may be subject to other regulations and policies and should be handled accordingly. Therefore, different privacy measures should be advocated for different types of personal data in each country.

[0066] Regardless of the foregoing, this disclosure also anticipates implementation schemes that allow users to selectively block the use or access to personal information data. That is, this disclosure anticipates providing hardware and / or software components to prevent or block access to such personal information data. For example, with regard to advertising delivery services, the inventive technology can be configured to allow users to opt-in or opt-out at any time during or after service registration to participate in the collection of personal information data. In another example, users may choose not to provide emotion-related data for a targeted content delivery service. In yet another example, users may choose to limit the duration for which emotion-related data is retained, or to completely prohibit the development of underlying emotional states. In addition to providing opt-in and opt-out options, this disclosure also anticipates providing notifications related to access to or use of personal information. For example, users may be notified when downloading an application that their personal information data will be accessed, and then reminded again just before the application accesses the personal information data.

[0067] Furthermore, the intent of this disclosure is that personal information data should be managed and processed in a manner that minimizes the risk of unintentional or unauthorized access or use. Once data is no longer needed, this risk can be minimized by restricting data collection and deleting data. Additionally, and where applicable, including in certain health-related applications, data deidentification can be used to protect user privacy. Deidentification can be facilitated, where appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of stored data (e.g., collecting location data at the city level rather than the address level), controlling how data is stored (e.g., aggregating data among users), and / or other methods.

[0068] Therefore, while this disclosure broadly covers the use of personal information data to implement one or more of the various disclosed embodiments, it is also contemplated that various embodiments can be implemented without access to such personal information data. That is, various embodiments of the present invention will not become inoperable due to the absence of all or part of such personal information data. For example, preferences can be inferred based on non-personal information data or a minimal amount of personal information such as content requested by a device associated with a user, other non-personal information available to the content delivery service, or publicly available information, thereby selecting content and delivering it to the user.

[0069] For illustrative purposes, the foregoing description uses specific names to provide a thorough understanding of the described embodiments. However, it will be apparent to those skilled in the art that specific details are not required to practice the described embodiments. Therefore, for illustrative and descriptive purposes, the foregoing description of specific embodiments described herein is presented. They are not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to those skilled in the art that many modifications and variations are possible in light of the teachings above.
