[0021] In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that embodiments of the present disclosure may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail to avoid obscuring the present disclosure.

[0022] Current solutions are unable to effectively mitigate eye fatigue and discomfort caused by the user's eye alignment and focusing challenges. There is a need for an improved system that can relieve eye fatigue and provide a more comfortable user experience when wearing a head-mounted display.

[0023] The present subject matter discloses systems, devices, and methods for alleviating eye fatigue experienced in a user device. The user is allowed to adjust the distance between their eyes and a display panel, thereby reducing eye fatigue and discomfort. For example, users with eyes that are deeper relative to their forehead or with different eyelash lengths can make these adjustments to avoid and / or alleviate discomfort when attempting to focus on a visual display in a head-mounted device.

[0024] The embodiments described herein address the foregoing and other disadvantages by providing a system for alleviating eye fatigue in a head-mounted display. The system includes an adjustable facial interface bracket and an extender bracket that can be coupled to the head-mounted display device. An actuation mechanism is incorporated to define a spatial distance between the facial interface bracket and the extender bracket. This allows the user to customize the distance between their eyes and the display panel, thereby reducing eye fatigue and enhancing the overall comfort of the head-mounted display. The system provides a flexible and user-friendly solution for enhancing the user experience and alleviating eye fatigue in a head-mounted display.

[0025] Figure 1A and Figure 1B An example head-mounted display system 100 in accordance with aspects of the present disclosure is shown. Figure 1A A rear isometric view of the head-mounted display device 100 is shown, while Figure 1BShows a front view expanded diagram of a head-worn display device. As shown in FIG. 1, the head-worn display system 100 may include a head-worn display device 102 and a facial interface system 108, a strap assembly (not shown), and an audio subsystem (not shown). The head-worn display device may include any type or form of display device or system that is worn on or about a user's head and displays visual content to the user. The head-worn display device may display visual content in any suitable manner, including via a display panel (e.g., an LCD or LED display panel), a projector, a cathode ray tube, an optical combiner, etc. The head-worn display device may display content in one or more media formats of various media formats. For example, the head-worn display device may display video, photos, and / or computer-generated imagery (CGI).

[0026] In the example of FIG. 1, the head-worn display device 102 includes a display housing 110, and various components of the head-worn display device 102 may be mounted inside and / or to the display housing, and these components include a lens 104 and / or various electronic components (including the display components described herein). The display housing 110 may include a housing rear surface (not shown) and a peripheral surface 113 that substantially surrounds one or more internal components, and an opening 115 that surrounds a viewing area 106 on the front side of the display housing 110.

[0027] The head-worn display device (e.g., the head-worn display device 102) may provide a diverse and unique user experience. Some head-worn display devices may provide a virtual reality (VR) experience (i.e., they may display computer-generated content or pre-recorded content to the user and block the user's view of their real-world environment), while other head-worn displays may provide a real-world experience (i.e., they may display live images from the physical world). The head-worn display may also provide any mix of live content and virtual content. For example, virtual content may be projected (e.g., via optical or video see-through) onto a view of the physical world, which may provide the user with an augmented reality (AR) experience or a mixed reality (MR) experience. The head-worn display device (e.g., the head-worn display device 102) may be configured to be mounted to the user's head in a variety of ways. Some head-worn display devices may be incorporated into glasses or goggles. Other head-worn display devices may be incorporated into helmets, hats, or other headgear.

[0028] The head-wearable display device 102 may include or be implemented in combination with an artificial reality system. Artificial reality refers to a user experience of the audio, visual, tactile, and / or other sensory outputs of the device, which have been created by the device or adjusted by the device relative to the real world before being presented to the user. Artificial reality may refer to, for example, virtual reality (VR), augmented reality (AR), mixed reality (MR), hybrid reality, or some combination and / or derivative thereof. Artificial reality content may include content generated entirely by a virtual device and / or content generated by the system, and / or may include virtual content that is combined with real-world content that can be directly viewed by the user (e.g., through a transparent or translucent portion of the device) or captured by one or more system cameras and displayed to the user by the device.

[0029] Artificial reality content may include video, audio, tactile feedback, or some combination thereof, and any one of video, audio, tactile feedback, or some combination thereof may be presented in a single channel or in multiple channels (e.g., stereoscopic video that produces a three-dimensional effect for the viewer). Additionally, artificial reality may also be associated with applications, products, accessories, services, or some combination thereof, which are used, for example, to create content in artificial reality and / or otherwise for use in artificial reality (e.g., to perform activities in artificial reality). An artificial reality system that provides artificial reality content may be implemented on a variety of platforms, including a head-wearable display connected to a main computer system (sometimes referred to as a head-mounted display (HMD), and not intended to require that the HMD is currently worn on the user's head), a stand-alone HMD, a mobile device or computing system, or any other hardware platform capable of providing artificial reality content to one or more viewers.

[0030] When the user wears the head-wearable display system 100, the facial interface system 108 may be configured to comfortably rest on an area of the user's face that includes the area around the user's eyes. For example, the facial interface system 108 may include an interface pad 127 that is configured to rest on a portion of the user's face (e.g., at least a portion of the user's nose, cheeks, temples, and / or forehead facial regions). The facial interface system 108 extends around the viewing area 106 and may be arranged to allow the user wearing the head-wearable display device 102 to view through the lens 104 of the head-wearable display device 102 without interference from external light.

[0031] The head-wearable display device 102 may include a display panel 118 disposed within a display housing 110. The display panel 118 may be implemented as a liquid crystal display (LCD) panel, a light-emitting diode (LED) display panel, or a display panel implementing other display pixel technologies.

[0032] As Figure 1A shown, the display panel 118 may be disposed within the display housing 110 so as to overlap with one or more left-eye lenses 104L and one or more right-eye lenses 104R such that a user may view an image generated by a corresponding region of the display panel 118 through the one or more left-eye lenses 104L and the one or more right-eye lenses 104R. For example, different portions of the display panel 118 may be visible to each eye of the user, where the different portions of the display panel are separated by a partitioning region (e.g., portions of a separate eye cup for each lens, a central partitioning separator, etc.) that extends between the display panel 118 and a mounting structure for the one or more left-eye lenses 104L and the one or more right-eye lenses 104R. Such a configuration may enable the display panel 118 to present different images to each eye of the user, thereby allowing the user to perceive three-dimensional content. Although a single continuous display panel 118 (a continuous panel having display regions for each eye of the user) is shown in Figure 1A , it should be understood that the head-wearable display device 102 may be equipped with multiple display panels (e.g., one display panel, such as one LCD display panel for each eye of the user).

[0033] As Figure 1B shown, the system 100 may include an eye-relaxing device that includes a face interface bracket 106 and an extender bracket 109. The orientation of the coupling between the interface bracket 106 and the extender bracket 109 may be adjusted to increase or decrease the distance between the user's eyes and the display panel 118. The extender bracket may include multiple parts or a single (integral) part as Figure 1B shown. The interface bracket and the extender bracket may include materials such as, but not limited to: metals, polymers, plastics, and wherein the materials are configured to have rigidity to maintain a locked position when setting the coupling between the interface bracket and the extender bracket. On the other hand, the materials include an elastic modulus that allows the materials to bend and / or deform when a force is applied to the system components and then return to their initial structure when the force is removed from the system components.

[0034] The display housing 110 can be formed of a rigid material (e.g., rigid plastic) that supports and protects the internal components (e.g., display panel 118 and other electronics) housed therein. At least a portion of the display housing 110 (e.g., the portion of the display housing 110 surrounding the viewing area 106) can include a light-absorbing material that prevents external light from passing through and prevents reflection of light that accidentally enters the viewing area 106. By ensuring that nearly all of the light visible to the user is emitted from the display panel 118, occluding external light and / or preventing reflection of light in the viewing area 106 of the head-mounted display device 102 can greatly enhance the user's immersive viewing experience. The head-mounted display device 102 can be provided with a connection cable (not shown) that communicatively couples the head-mounted display device 102 to a remote system (e.g., a remote computing device (e.g., a desktop computer, a tablet computer, a game console, a server, a dedicated computer, etc.)) that generates the content to be displayed by the display panel 118. However, it should also be understood that the head-mounted display device 102 can be wirelessly coupled to the remote computing device.

[0035] Figure 2A , Figure 2B and Figure 2C FIGS. show a system 200 configured to provide eye fatigue mitigation using a head-mounted display device. The system 200 can include a facial interface (FI) bracket 204 and an extender (ER) bracket 202. The facial interface (FI) bracket 204 and the extender bracket 202 can be oriented such that the facial interface bracket 204 and the extender bracket 202 can move parallel to each other. For example, in a commercial implementation, when the extender bracket 202 is fixed and coupled to the housing 102, the facial interface bracket 204 can move forward toward the display panel and backward away from the display panel. The facial interface bracket 204 and the extender bracket 202 can be coupled to each other, where the distance between the upper surface of the extender bracket 204 and the upper surface of the facial interface bracket 204 is defined by an actuation mechanism 206. In the system 200, the actuation mechanism 206 can include a fastener arrangement that allows the facial interface bracket 204 and the extender bracket to move relative to each other. Once the desired distance between the facial interface bracket 204 and the housing 102 is reached, the fasteners of the actuation mechanism 206 can be engaged to hold the desired distance between the facial interface bracket and the extender bracket in a fixed position. As Figure 2A , Figure 2B and / or Figure 2CAs depicted in the enlarged cross-sectional view, the actuating mechanism 206 may include a slot-type interface. In particular, the outer surface of the face interface bracket 204 may include a protrusion (or plug) 210 that extends perpendicularly from the surface of the face interface bracket. The extender bracket 202 may include a plurality of grooves 208 defined in the outer surface of the extender bracket. The grooves 208 may engage the protrusion 210 when the user determines the distance between the face interface bracket 204 and the extender bracket 202. In some embodiments, the system 200 may include multiple actuating mechanisms to maintain symmetry in the system. The grooves 208 may be defined in the surfaces of the face interface bracket 204 and the protrusion 210.

[0036] Figure 3A and Figure 3B FIG. shows a system 300 configured to provide eye fatigue mitigation using a head-wearable display device according to one or more embodiments. The system 300 may include a face interface bracket 304 and an extender bracket 302. The face interface bracket 304 and the extender bracket 302 may be configured to slide past each other. The system 300 may include an actuating mechanism 306. The extender bracket 302 may include a locking insert 311 having inclined grooves 310. The inclined grooves 310 may be configured to engage a retaining pin 308. The locking insert 311 may include locking nodules 312. The locking nodules 312 may include protrusions that extend from the surface of the locking insert 311. The locking insert 311 may engage a mating groove 314. The interface between the locking nodules 312 and the mating groove 314 may lock the positional distance between the face interface bracket 304 and the extender bracket 302. The extended actuating mechanism 306 of the system 300 may include a slider 308. The slider 308 may include a protrusion that extends from the surface of the face interface 304. The slider 308 may include a retaining pin fixed to the face interface bracket 304. When the user manipulates the locking insert up and down, the extender bracket 302 may move forward and backward. Additionally, the movement of the extender bracket 302 may be defined by engaging the retaining pin in the inclined grooves 310 of the locking insert.

[0037] Figure 4A 、 Figure 4B and Figure 4CA system 400 configured to provide eyestrain relief using a head-worn display device is shown, according to one or more embodiments. System 400 can include a facial interface bracket 404 and an extender bracket 402. Facial interface bracket 404 and extender bracket 402 can be configured to slide past each other. An actuation mechanism 406 between facial interface bracket 304 and extender bracket 402 can include a tab device 410. Tab device 410 can include two components. A first component can include a tab 411. Tab 411 can be oriented to translate in a channel 413. Sliding tab 411 can be retained in the channel by a pin 412. Pin 412 can anchor tab 410 to the facial interface bracket. Pin 412 can be an extrusion from a surface of the interface bracket to similarly function as an anchor for sliding tab 411. After the user has defined the relative distance between facial interface bracket 404 and extender bracket 402, the user can lock the desired position in place by pushing the tab along the axis to engage a portion of one of grooves 414. A portion of tab 411 can be configured to engage groove 414 defined by an outer surface of extender bracket 302. The user can release the lock created by the tab device by sliding tab 411 away from groove 414.

[0038] Figure 5A 、 Figure 5B and Figure 5C A system 500 configured to provide eye strain relief using a head-worn display device, according to one or more embodiments, is shown. System 500 may include a facial interface bracket 504 and an extender bracket 502. Facial interface bracket 504 and extender bracket 502 may be configured to slide along one another to extend or contract the distance between a user's face and a display panel, similar to previous embodiments. Actuation mechanism 506 may include a cantilever 510 actuated by pressing a button 508. On an outer surface of extender bracket 502, cantilever 510 may be defined within the bracket's surface by defining a channel surrounding cantilever 510. A user may bend cantilever 510 by pressing button 508. Button 508 may include one end of cantilever 510. Pressing button 508 may cause the cantilever to bend along the portion of the cantilever coupled to the surface of extender bracket 502. When the cantilever is bent, the free end of the cantilever, which may include a protrusion 512, may disengage from a recess 514 defined by the outer surface of facial interface bracket 504. The facial interface bracket 504 can include a plurality of both-channeled grooves 514 configured to provide a resting point for the actuation mechanism. The actuation mechanism can be oriented so that when the housing 102, facial interface 504, and extender bracket 502 are coupled, the actuation mechanism is blocked by a portion of the housing 102. This orientation configuration can reduce the possibility of inadvertent actuation of the coupled device.

[0039] Figure 6A and Figure 6B According to one or more embodiments, Figure 5A 、 Figure 5B and Figure 5C In some embodiments, the system 500 can include a configuration in which the extender bracket 602 can include two parts 606 and 608 (as depicted in FIG. 6 ), rather than a single part as depicted in FIG. 5 .

[0040] Figure 7A 、 Figure 7B 、 Figure 7C 、 Figure 7D 、 Figure 7E and Figure 7F A system 700 configured to provide eye strain relief using a head-worn display device, according to one or more embodiments, is shown. System 700 may include a facial interface bracket 704 and an extender bracket 702. Facial interface bracket 704 and extender bracket 702 may be configured to slide along one another to extend or contract the distance between a user's face and a display panel, similar to previous embodiments. Actuation mechanism 706 may include a flexible cantilever 710 actuated by pressing a button 708. On an outer surface of extender bracket 702, the cantilever may be defined within the bracket's surface by defining a channel surrounding the bracket. A user may bend the cantilever by pressing button 708. The button may include one end of the cantilever. Pressing the button may cause cantilever 710 to bend along the portion of cantilever 710 coupled to the surface of extender bracket 702. When cantilever 710 is bent, the free end of cantilever 710, which may include a protrusion 712, may disengage from a recess 714 defined by the outer surface of facial interface bracket 704. The facial interface bracket 704 can include a plurality of dual-channel grooves 714 configured to provide resting points for the actuation mechanism 706. In some embodiments, the actuation mechanism 706 can include an alignment fixture 718. The alignment fixture can include a protrusion 718 extending from a surface of the facial interface bracket 704. The protrusion 718 can extend through an alignment channel 716 defined in a surface of the extender bracket 702. The actuation mechanism 706 can be oriented so that when the display panel is adjacent to the facial interface 704 and coupled to the extender bracket 702, the actuation mechanism is blocked by a portion of the housing 102. This orientation configuration can reduce the likelihood of inadvertent actuation of the coupling device 706.

[0041] Figure 8A 、 Figure 8B 、 Figure 8C and Figure 8DIllustrated is a system 800 configured to provide eye fatigue mitigation using a head - wearable display device, according to one or more embodiments. The system 800 may include a face interface bracket 804 and an extender bracket 802. The face interface bracket 804 and the extender bracket 802 may be configured to slide along each other to extend or contract the distance between the user's face and the display panel, similar to previous embodiments. The actuation mechanism 806 may include a curved cantilever 810 that is actuated by pressing on the distal portion of the cantilever 808. On the outer surface of the extender bracket 802, the cantilever 810 may be defined within the surface of the bracket by defining a channel that wraps around the bracket. When the cantilever bends, the free end of the cantilever, which may include a protrusion 812, may disengage from a groove 814 defined by the outer surface of the face interface bracket 804. The face interface bracket 804 may include a plurality of dual - channel grooves. The extender bracket 802 may define an aperture 816 that allows the user to see numbers placed on the outer surface of the face interface bracket. When the user extends the actuation mechanism 806, movement to each successive groove 814 may show a different numerical indicator associated with the relative distance between the extender bracket 802 and the face interface bracket 804. The actuation mechanism 806 may be oriented such that when the display panel, the face interface 804, and the extender bracket 802 are coupled, the actuation mechanism is blocked by a portion of the housing 102. This orientation configuration may reduce the likelihood of unintentional actuation of the coupled devices.

[0042] Figure 9A and Figure 9B Illustrated is a system 900 configured to provide eye fatigue mitigation using a head - wearable display device, according to one or more embodiments. The system 900 may include a face interface bracket 904 and an extender bracket 902. The face interface bracket 904 and the extender bracket 902 may be configured to slide along each other to extend or contract the distance between the user's face and the display panel, similar to previous embodiments. The actuation mechanism 906 may include a biased latch 914 that is activated by a button 912. The inner surface of the face interface bracket 904 may include a latch housing 908 that extends from the surface. The surface of the latch housing 908 may define a plurality of grooves 910. The latch 914 may rest in successive grooves 910 to lock the distance between the face interface bracket 904 and the extender bracket 902. When the button 912, which is coupled to the surface of the extender bracket 902, is pressed, the spring - loaded latch 914 may be activated. The button 912 may be biased such that its resting (un - actuated position) will lock the biased spring latch 914 in place. Once the button 912 is pressed, a tip 913 extending from the button may transfer force to the spring latch 914 such that the spring latch 914 bends and disengages from the groove 910 in the latch housing 908.

[0043] Figure 10A 、Figure 10B and Figure 10C illustrates a system 1000 configured to provide eye fatigue mitigation using a head - wearable display device, according to one or more embodiments. The system 1000 may include a face interface bracket 1004 and an extender bracket 1002. The face interface bracket 1004 and the extender bracket 1002 may be configured to slide along each other to extend or contract the distance between the user's face and the display panel, similar to previous embodiments. The actuation mechanism 1006 may include a biased latch 1014 that is activated by a button 1012. The spring latch 1014 may include a cantilever member having a free end 1017 and an anchored end 1016. The anchored end may be coupled to the extender bracket 1002. The inner surface of the face interface bracket 1004 may include a latch housing 1008 that extends from the surface. The surface of the latch housing 1008 may include a plurality of ridges (teeth) 1023 that define a plurality of grooves 1010. A tip 1013 on the opposite surface of the button may rest in successive grooves 1010 to lock the distance between the face interface bracket 1004 and the extender bracket 1002. In some embodiments, the engagement intersection point 1021 between the interface bracket 1004 and the button 1012, the cross - sectional surface between the button and the interface bracket may be angled. When disengaging from the locked state, pressing the button 1012 may slide the button across the surface of the interface bracket 1004 at the engagement intersection point 1021. When the force acting on the button is removed, the biased spring latch 1014 may press the button 1012, and the movement of the button will stop when the angled surfaces of the button and the interface bracket no longer slide past each other at the engagement intersection point 1021. The button 1012 may be biased such that its resting (non - actuated position) will lock the free end 1017 of the biased spring latch 1014 in place. When the button 1012 is pressed, the spring latch 1014 may be activated. The spring latch may engage in a channel 1019 defined by the opposite surface of the button 1012 at the free end 1017. Once the button 1012 is pressed, the tip 1013 extending from the button may transfer a force to the spring latch 1014, causing the spring latch 1014 to bend and causing the tip 1013 to disengage from the grooves 1010 in the latch housing 1008. When the mechanism 1006 slides up and down, the free end 1017 of the spring latch 1014 may strike / brake the teeth 1023 of the housing 1008. The operation of the mechanism sliding up and down to move back and forth between the locked position and the unlocked position may produce both an audible feedback and a tactile feedback as the bracket passes through each position.

[0053] As used herein, the phrase "at least one of" after a series of items, and the terms "and" or "or" used to separate any items in a plurality of items, modify the list as a whole, rather than each member of the list (i.e., each item). The phrase "at least one of" does not require the selection of at least one item; rather, the phrase allows the meaning that includes at least one of any of the plurality of items, and / or at least one of any combination of the plurality of items, and / or at least one of each of the plurality of items. By way of example, the phrase "at least one of A, B, and C" or "at least one of A, B, or C" means only A, only B, or only C; any combination of A, B, and C; and / or at least one of each of A, B, and C.

[0054] As used in the specification or claims, the term "comprising", "having", etc. is intended to be included in a manner similar to the term "including", as explained when "including" is used as a transitional word in a claim. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration". Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or superior to other embodiments.

[0055] Unless otherwise specified, a reference to an element in the singular is not intended to mean "one and only one" but "one or more". All structural and functional equivalents of the elements of the various configurations described throughout this disclosure that are known or later become known to those of ordinary skill in the art are hereby expressly incorporated by reference and are intended to be covered by the claimed subject matter. In addition, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is expressly recited above.

[0056] Although this specification contains many details, these details should not be construed as limiting the scope of what may be claimed, but rather as describing particular embodiments of the subject matter. Certain features described in the context of separate embodiments in this specification may also be implemented in combination in a single embodiment. Conversely, various features described in the context of a single embodiment may also be implemented separately in multiple embodiments or in any suitable sub-combination. In addition, although features may be described above as acting in certain combinations and even initially claimed as such, in some cases, one or more features from a claimed combination may be removed from that combination, and the claimed combination may cover a sub-combination or a variation of a sub-combination.

[0057] The subject matter of this specification has been described with respect to specific aspects, but other aspects may also be implemented and are within the scope of the appended claims. For example, although the operations are described in a particular order in the figures, this should not be construed as requiring that the operations be performed in the particular order shown or in sequential order, or that all of the illustrated operations be performed to achieve the desired result. The acts recited in the claims may be performed in a different order and still achieve the desired result. As one example, the processes described in the figures do not necessarily need to be in the particular order or sequential order shown to achieve the desired result. In some cases, multitasking and parallel processing may be advantageous. Additionally, the separation of the various system components of the above aspects should not be construed as requiring such separation in all aspects. Other variations are within the scope of the appended claims.
