Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is a PCT application of, and claims priority to, U.S. Utility Patent Application No. 17 / 021,822, filed on September 15, 2020, which is a non-provisional application of, and claims priority to, U.S. Provisional Patent Application No. 62 / 901,471, filed on September 17, 2019, both of which are entitled “ADJUSTABLE HEAD-MOUNTED DISPLAY,” the entire texts of which are incorporated herein by reference. Background Art

[0003] Head-mounted displays are used in a variety of fields, including engineering, medicine, the military, and video gaming. In some cases, a head-mounted display can present information or images to a user as part of a virtual reality or augmented reality environment. As an example, a user can wear a head-mounted display while playing a video game to immerse the user in the virtual environment.

[0004] Conventional head mounted displays provide insufficient or no adjustment to accommodate different head sizes and / or adjust the tightness of the head mounted display on the user. As a result, some users may find it difficult to wear the head mounted display comfortably and pleasantly. For example, if it is too snug, the head mounted display may not be comfortable to wear. Alternatively, if it is too loose, the head mounted display may not be properly secured to the user. As a result, conventional head mounted displays may not provide sufficient mechanisms to accommodate different users, allow quick and convenient adjustment, and / or properly and comfortably wear the head mounted display.

[0051] As described above, head mounted displays (HMDs) have a wide range of applications, and in some cases, may need to accommodate different head sizes between different users. However, conventional HMDs provide little adjustment to accommodate different users and / or incrementally tighten and loosen the HMD to the user. For example, conventional HMDs may use elastic bands or hook and loop bands to fix the HMD to the user's head. However, such mechanisms are quite crude and basic, and users may find it difficult to adjust the HMD instantly and / or in small increments. In this way, the HMD may not be securely mounted to the user and / or the user may spend time re-adjusting or re-tightening the HMD. However, such changes may detract from the utility of the HMD and / or may have a negative impact on the user experience. In addition, for example, failure to properly fix or install the HMD may affect the quality of images presented in virtual reality (VR) and / or augmented reality (AR) environments. Conventional HMDs may also include wires, cables, or other cords that may tangle or increase the volume of the HMD. Therefore, over an extended period of time, the HMD may be less comfortable and / or less convenient to wear.

[0052] The present application describes, in part, an HMD that fits snugly, comfortably, and securely around or to a user's head. In some cases, an HMD according to the present application may take a variety of forms, including helmets, eye shields, goggles, masks, glasses, and other head or eye wearables worn on a user's head. The HMD may include a front portion having a display worn on the user's face (adjacent to the eyes) that outputs images (or other content) for the user to observe. In some cases, these images may be output by an application or a computing device (e.g., a video game controller) that is communicatively coupled to the HMD. In addition, in some cases, a user may operate a handheld controller in conjunction with the HMD to further engage the user in a VR or AR environment.

[0053] The rear of the HMD may include a basket, a bracket, a support, a frame, or a strap configured to be fixed around the rear of the user's head. In some cases, the strap may be engaged below and / or with the occipital lobe to clamp the rear of the user's head and fix the HMD to the user. In some cases, the strap or a portion of the strap may be spring-loaded or tension-loaded to maintain a constant pressure on the rear of the head. Such pressure may help to fasten the HMD to the user by ergonomically conforming to the head. Additionally or alternatively, the strap may include one or more ball joints for conforming to the user's head. For example, the strap may be connected to a portion of the HMD via a ball joint (e.g., a rear housing) for articulating around one or more axes to comfortably position the strap on the head. In addition, in some cases, the strap may include different material thicknesses and / or gaps for providing flexure around one or more axes. The multi-axis flexure may allow the strap to evenly distribute force to the rear of the head for fixing the HMD to the user.

[0054] In some cases, the strap may include a portion that engages the user's head above the occipital lobe and that extends circumferentially and / or radially around at least a portion of the user's head. In some cases, the HMD may also include a strap that engages the top of the user's head. Thus, in some cases, the HMD may include multiple portions that are designed to engage different or corresponding portions of the user's head. For example, a first portion of the HMD may engage the user's head below the occipital lobe, a second portion of the HMD may engage the user's head above the occipital lobe, and / or a third portion may engage along the top of the user's head. These portions of the HMD may coordinate to secure and / or mount the HMD to the user's head.

[0055] The HMD can adjust and adapt to different head sizes between users, and / or the HMD can be tightened and loosened incrementally to the user. For example, the HMD may include strands, ropes, sections, strips, straps or other components that are operably connected to the front of the HMD and the rear of the HMD. These components can be engaged with an actuable mechanism, fastener, fixture or actuator to fix and release the HMD to the user. As an example, these components may include attachment mechanisms or adjustable elements, such as teeth, connectors, slits, lugs, notches, lugs and / or other slots that extend along a portion of the length of the component and engage with the actuator. These actuators may include mechanisms that are configured to engage with the slots at different portions along the length of the component, for example, to tighten and loosen the HMD from the user's head. For example, these actuators may include attachment mechanisms or adjustable elements, such as dials, levers, wheels, slides, buckles, arms and / or knobs.

[0056] In some cases, the engagement between these members and the actuators may be similar to a ratchet mechanism, a slide and lock mechanism, a friction mechanism, etc. Through this engagement and by actuating (e.g., pulling, twisting, rotating, etc.) these actuators, the length of these members may be adjusted. For example, the user may actuate these actuators to adjust the length of the members and position the HMD relative to the user's eyes and / or increase and decrease the tightness of the HMD on the user. These actuators may increase or decrease the distance or gap distance between the front of the HMD and the back of the HMD. In this way, the user may be provided with the option of adjusting the distance between the front and back of the HMD to allow the user to incrementally tighten the HMD to a desired position or tightness. In some cases, these actuators may adjust the members to but not exceed a maximum extension, and reduce to but not below a minimum extension.

[0057] As an example, these actuators may include a rotatable knob having a gear that engages with a slot positioned along a portion of the length of the member. Biasing (e.g., rotating) the actuator in a first direction may cause the member to retract, thereby shortening the length and tightening the HMD to the user. When tightening, the front and rear of the HMD may extend or transform inward, together, or toward each other to apply pressure on the user's head to keep the HMD in place. Biasing (e.g., rotating) the actuator in a second direction that may be opposite may cause the member to extend or move outward or away from each other, thereby increasing the length and releasing the HMD from the user. Therefore, these members and actuators may be operably coupled, interact, interconnected, or otherwise engaged to fix and / or mount the HMD to the user. The actuator may also allow the user to conveniently adjust the HMD on the fly and / or tighten and loosen the HMD incrementally.

[0058] In some cases, an HMD according to the present application may include multiple components that secure and / or mount the HMD to a user and multiple actuators that are operably engaged with the corresponding components. For example, the HMD may include one or more cross members that extend between the front of the HMD and the rear of the HMD at opposite sides of the HMD. The first end of the one or more cross members may be hingedly, rotatably or pivotally connected to a display worn on the face of the user, and the second end of the one or more cross members may extend rearward into the housing of the HMD and engage with one or more rear actuators. The one or more cross members may engage with the one or more rear actuators at different positions along the length of the one or more cross members to allow the length to be increased or decreased, thereby loosening or tightening the HMD to the user.

[0059] Additionally or alternatively, the HMD may include one or more top members extending at the top of the HMD between the front of the HMD and the back of the HMD. A first end of the one or more top members may be coupled to the top of the display, while a second end of the one or more top members may extend toward the back of the HMD and engage with one or more top actuators. The one or more top members may engage with the one or more top actuators at different locations along the length of the one or more top members to allow the length to be increased or decreased, thereby loosening or tightening the HMD to the user, respectively.

[0060] Thus, when the HMD is worn by a user, the one or more cross members may extend along opposite sides of the user's head, adjacent to the user's ears, and the one or more top members may extend along the top of the user's head. In this sense, the one or more cross members and the one or more top members, when tightened, may be used to secure the HMD to the user's head in multiple directions, and the HMD may engage or mount to corresponding parts of the user. Thus, the one or more cross members and the one or more top members may help keep the HMD in a desired position. However, the HMD may include other members designed to engage with different parts of the user, other than those discussed herein.

[0061] These actuators may be conveniently located on the HMD and may be conveniently actuated by the user to loosen or tighten the HMD. For example, the actuator that offsets the one or more cross members may be located at the rear of the HMD, while the actuator that offsets the one or more top members may be located at the top of the HMD. In some cases, the one or more actuators may be centrally aligned on the HMD. However, in some cases, the top actuator and / or the rear actuator may be positioned close to each other, such as at the rear of the HMD. For user convenience, such positioning may position the top actuator and the rear actuator close to each other.

[0062] In some cases, the HMD may include one or more wire routing sections or components that guide wires between the front and rear of the HMD. For example, the rear of the HMD may include a compartment with a wireless transceiver, a battery, a microphone, an input / output device, and / or other components that allow the HMD to operate. In some cases, the front may include a display and / or an antenna. One or more cables may communicatively couple the front and rear of the HMD to provide power, information signals, or images to be output on the display. In some cases, wires, optical fibers, and / or cables may be routed through the one or more wire routing sections to alleviate potential problems of wire entanglement and / or loss of aesthetic appearance of the HMD. For example, the wire routing section may include a housing and a sliding member operably engaged in the housing. The wire routing section may be transformed or moved between an extended state and a retracted state. In order to extend at different lengths, the wire routing section may include a channel for routing wires between the front and rear of the HMD. That is, the wire may include enough slack (or service loop) to allow the sliding member to extend at different lengths. As an example, wires may be disposed within or coupled to a portion of a wire routing portion, such as a slider, and wires that communicatively couple an antenna located at the front of the HMD to an antenna located at the rear of the device may be coupled to the slider and / or a portion on the housing for routing through the wire routing portion. In some cases, the slider may traverse the housing and extend telescopically to extend and retract within the housing as the user tightens and loosens the HMD.

[0063] In some cases, the wire routing portion and the one or more top members may be integrally formed. For example, the top member may include embedded wires to communicatively couple the front and rear of the HMD. The top member may extend from the jacket at various lengths via actuation of one or more actuators. In addition, the top member may be retracted within the jacket via actuation of the one or more actuators. Thus, the top member and the wire routing portion are integrally formed as a single component (e.g., possibly similar to a compact housing) to connect and communicatively couple the front and rear of the HMD.

[0064] Additionally or alternatively, in some cases, the HMD may include a flexible printed circuit (FPC) that extends from the front of the HMD to the back and communicatively couples one or more components of the HMD. In some cases, the FPC may extend through a jacket and / or sheath that, in some cases, may connect or abut the top member and the FPC. In some cases, the FPC may include a service loop or slack that allows the FPC to extend and retract. In some cases, the service loop may be disposed inside the jacket. For example, the FPC may enter the jacket and traverse or wrap around the jacket and exit the jacket at opposite ends.

[0065] The present disclosure provides a comprehensive understanding of the principles of the structure, function, manufacture, and use of the systems and methods disclosed herein. One or more examples of the present disclosure are shown in the accompanying drawings. It will be understood by those of ordinary skill in the art that the systems and methods specifically described herein and shown in the accompanying drawings are non-limiting embodiments. Features shown or described in conjunction with one embodiment may be combined with features of other embodiments, including features between systems and methods. Such modifications and variations are intended to be included within the scope of the appended claims.

[0066] Figure 1 An exemplary head mounted display (HMD) 100 positioned on or around the head of a user 102 is shown. The HMD 100 may include a front portion 104 and a rear portion 106 that are secured to the head of the user 102 when tightened. The front portion 104 may include a display 108 positioned in front of or above the eyes of the user 102 to render images output by an application (e.g., a video game). In general, the display 108 may represent and / or refer to a housing in which one or more displays are housed. In some cases, the application may be executed on a computing device (e.g., a personal computer (PC), a game controller, etc.) associated with the HMD 100 and / or communicatively coupled to the HMD. The display 108 may output a series of images (frames) observed by the user 102 through optical devices within the HMD 100, so that the user perceives the images as if immersed in a VR or AR environment.

[0067] The back 106 of the HMD 100 may include components for performing the functions of the HMD 100, such as logic, hardware, memory, processors, batteries, etc. Additionally or alternatively, in some cases, some or all of these components may be located at the front 104 of the HMD 100. To communicatively couple the front 104 and back 106 of the HMD 100, the HMD 100 may include one or more wires, strings, and / or cables 110 extending between the front 104 and back 106. In some cases, the cable 110 may be routed along the side of the HMD 100. The cable 110 may provide signal processing, power, and other controls between the front 104 and back 106 of the HMD 100. For example, the back 106 of the HMD 100 may include a battery, and power may be routed to the display 108 via the cable 110. However, the cable 110 may be routed through other parts of the HMD 100.

[0068] HMD 100 includes supports, collars, frames, mounts, and / or other structures that attach, secure, mount, stabilize, and / or otherwise fix HMD 100 to user 102. In some cases, the structures of HMD 100 can position display 108 relative to the eyes of user 102. In some cases, these structures can coordinate with each other to support the weight of HMD 100 and provide a balanced and comfortable experience when HMD 100 is worn by user 102. In some cases, these structures can also include curved surfaces that generally conform to the contours or ergonomics of the head (or face) of user 102.

[0069] In some cases, the HMD 100 may include multiple components and actuators that engage with each other to adjust for different head sizes and / or tighten and loosen the HMD 100 to and from the user 102. These components and / or actuators can adjust the structure of the HMD 100 to accommodate different users and / or can adjust the structure of the HMD according to user preferences. For example, the HMD 100 may include a top member 112 that traverses between the front 104 and the back 106 of the HMD 100 along the top (crown) of the user's 102 head or across the top of the user's head. In some cases, the top member 112 can rest on or contact the top of the user's 102 head. In some cases, top member 112 may include straps, bands, straps, ties, strings, or ties that are configured to operably change length (or exposed length) to tighten HMD 100 to user 102 and loosen HMD 100 from user 102. In some cases, top member 112 may be made of materials such as plastic, metal, rubber, composite materials, and / or any combination thereof.

[0070] The top member 112 may include a first end 114 coupled to the display 108 or at the front 104 of the HMD 100 and a second end extending toward the rear 106 (Z direction) of the HMD 100. Figure 1 As shown, the second end of the top member 112 can extend into a jacket 116 that extends from the rear 106 of the HMD 100 in a direction (Z direction) toward the front 104 of the HMD 100. The jacket 116 can be sized and configured to receive or accommodate the top member 112, a portion of the top member 112, and / or the second end of the top member 112.

[0071] The top member 112 may include teeth, tabs, hooks, tabs, adjustable elements or mechanisms, or other slots 118 that are longitudinally positioned between the first end 114 and the second end along the length (Z direction) or a portion of the length of the top member 112. The slots 118 may be operably coupled to or otherwise engaged with the top actuator 120 within the jacket 116. In doing so, the top member 112 may be operably coupled to the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100, or may be disposed between the front portion 104 and the rear portion 106 of the HMD 100. That is, the top member 112 may be coupled to the front portion 104 at the first end 114 via the display 108, and may be coupled to the rear portion 106 of the HMD 100 via the top member 112 and / or the second end of the top member 112 engaged with the top actuator 120. In some cases, the top actuator 120 may be similar to a dial, lever, wheel, slider, buckle, and / or knob that can be actuated (e.g., turned, twisted, rotated, pulled, etc.) to adjust the length of the top member 112.

[0072] The top actuator 120 may be attached, mounted, or otherwise coupled to the jacket 116. A first portion of the top actuator 120 may extend through the jacket 116 to be grasped by the user 102, while a second portion of the top actuator 120 may be disposed within the interior of the jacket 116 to operably engage with the slot 118 of the top member 112. For example, the top actuator 120 may include teeth, gears (e.g., spur gears), pinions, tabs, or sprockets that engage with the slots 118. In some cases, the engagement between the top member 112 and the top actuator 120 may be similar to a ratchet mechanism, a slide and lock mechanism, a female connector / male connector, a friction mechanism, etc. In this way, the top actuator 120 may cooperate with the top member 112 at different locations along the length of the top member 112 to allow the length of the top member 112 extending from the jacket 116 to increase or decrease.

[0073] As an example, the top actuator 120 may include a rotatable knob having a sprocket, and the top member 112 may include a slot 118 sized and configured to engage the sprocket, and vice versa. Rotating the top actuator 120 in a first direction (e.g., clockwise and / or about the Y axis) may cause the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 to move inward and approach each other (Z direction), thereby reducing the gap distance provided between the front portion 104 and the rear portion 106. The top actuator 120 may retract the top member 112 into and / or within the jacket 116 (Z direction), so that the HMD 100 may pull the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 inward to apply greater force or tension to the user 102. The pressure and / or force may tighten and / or secure the HMD 100 to the user 102. Additionally, when tightened, the top actuator 120 may lock and / or maintain engagement with the slot 118 to hold the HMD 100 in place, prevent the top member 112 from withdrawing from the jacket 116, and position the HMD 100 on the user 102. Rotating the knob in a second, opposite direction (e.g., counterclockwise and / or about the Y-axis) may cause the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 to move outward and apart from each other (e.g., in the Z-direction), thereby increasing the gap distance provided between the front portion 104 and the rear portion 106. In doing so, the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 may extend away from each other or be allowed to move away to apply less force or tension to the user 102 to loosen the HMD 100. In this sense, when loosened, the top member 112 can extend from the jacket 116 (Z direction) so that the front 104 and rear 106 of the HMD 100 are allowed to move apart and the user 102 can remove the HMD 100 and / or reduce the force applied by the HMD 100.

[0074] In some cases, actuating top actuator 120 can align display 108 vertically relative to the eyes of user 102. For example, extending and retracting top member 112 can provide slack or take up slack for adjusting the vertical position of display 108 on user 102's face.

[0075] Although Figure 1The jacket 116 is shown as a certain length, but the jacket 116 can be longer or shorter than the length shown. For example, the jacket 116 can be longer so that the slot 118 is enclosed or disposed within the jacket 116 between the fully extended state and the fully retracted state. That is, the slot 118 can be inside the jacket 116 so that the slot 118 is not visible from the outside of the HMD 100. Having the slot 118 disposed within the jacket 116 can prevent hair from being entangled in the slot 118 and / or the top actuator 120. Therefore, the top member 112 extends and retracts within the jacket 116 at various lengths, and the slot 118 can be disposed within the jacket 116.

[0076] Additionally, HMD 100 may include one or more adjustable members that traverse between front portion 104 and rear portion 106 of HMD 100 laterally (in the Z direction) or along the sides of the head of user 102. For example, HMD 100 may include first cross member 122 and second cross member 124 that extend from front portion 104 of HMD 100 toward rear portion 106 of HMD 100 along the sides of the head of user 102. In some cases, first cross member 122 may be located on a first side (e.g., the left side) of HMD 100, and second cross member 124 may be located on a second side (e.g., the right side) of HMD 100, spaced apart in the X direction. Figure 1 As shown, in some cases, the first cross member 122 and the second cross member 124 can be disposed on opposite sides of the HMD 100 or coupled to opposite sides of the display 108 .

[0077] In some cases, first cross member 122 and second cross member 124 may include or represent straps, bands, straps, strings, or straps of varying lengths to tighten HMD 100 to user 102 and loosen HMD 100 from user 102. For example, first cross member 122 may include a first end 126, where the first end is coupled to display 108 or at front 104 of HMD 100, and a second end that extends laterally toward rear 106 (Z direction) of HMD 100. In some cases, first cross member 122 and / or the second end of first cross member 124 may extend or move into a compartment or housing 128 located at rear 106 of HMD 100. Similarly, the second cross member 124 may include a first end coupled to the display 108 or at the front 104 of the HMD 100 and a second end extending toward the rear 106 (Z direction) of the HMD 100 and into the housing 128 .

[0078] In some cases, first end 126 of first cross member 122 and first end of second cross member 124 may be pivotally or hingedly, rotatably or pivotally attached, or otherwise coupled to display 108. Pivotally coupling to display 108 may allow first cross member 122 and second cross member 124 to manipulate, accommodate, and conform to different head sizes, or allow for angled positioning of display 108 on user 102.

[0079] Housing 128 may be sized and configured to receive first cross member 122 (or the second end of first cross member 122) and second cross member 124 (or the second end of second cross member 124). In some cases, first cross member 122 and second cross member 124 may extend telescopically into housing 128 of HMD 100 to allow first cross member 122 and second cross member 124 to extend from and retract within housing 128. As will be discussed herein, first cross member 122 and / or second cross member 124 may include teeth, tabs, hooks, adjustable attachment mechanisms, and / or other slots positioned along the length or portion of the length of first cross member 122 and second cross member 124. The slot of first cross member 122 and / or the slot of second cross member 124 may operably couple or otherwise engage a rear actuator located at rear portion 106 of HMD 100. Thus, first cross member 122 and second cross member 124 may couple front portion 104 of HMD 100 and rear portion 106 of HMD 100, or in other words, may be disposed between front portion 104 and rear portion 106 of HMD 100. In some cases, first cross member 122 and / or second cross member 124 may engage a rear actuator within housing 128.

[0080] The rear actuator may be similar to a dial, lever, wheel, slide, buckle, and / or a knob that can be actuated (e.g., turned, twisted, rotated, pulled, etc.). The rear actuator may include teeth, gears (e.g., spur gears), pinions, or sprockets that engage with the slots of the first and second cross members 122, 124. In some cases, the engagement between the first and second cross members 122, 124 and the rear actuator may be similar to a ratchet mechanism, a slide and lock mechanism, a female connector / male connector, a friction mechanism, etc. In this way, the rear actuator may cooperate with the first and second cross members 122, 124 at different locations along the length of the first and second cross members 122, 124, respectively, to allow the lengths of the first and second cross members 122, 124 to be adjusted via actuation of the rear actuator.

[0081] As an example, the rear actuator may include a rotatable knob having a sprocket, and the first and second cross members 122, 124 may include slots (similar to slots 118) that are sized and configured to engage with the sprocket. Rotating the rear actuator in a first direction (e.g., clockwise and / or about the Z-axis) may cause the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 to move inward and toward each other (Z-direction). When actuated in the first direction, the rear actuator may retract the first and second cross members 122, 124 into or within the housing 128, or toward the rear portion 106 of the HMD 100. Retracting the first and second cross members 122, 124 may cause the HMD 100 to apply a greater force or tension to the user 102 to tighten the HMD 100. When tightened, the rear actuator may lock and / or maintain engagement with the slots of the first and second cross members 122, 124 to hold the HMD 100 in place and position the HMD 100 on the user 102. Rotating the knob in a second, opposite direction (e.g., counterclockwise and / or about the Z-axis) may cause the front portion 104 of the HMD 100 and the rear portion 106 of the HMD 100 to move outward and apart from each other (e.g., in the Z-direction). In doing so, the force applied to the user 102 may be reduced and the HMD 100 may be released from the user 102. When released, the first and second cross members 122, 124 may extend from the housing 128, thereby pushing the front portion 104 and the rear portion 106 of the HMD 100 apart.

[0082] Using the top actuator 120 and the rear actuator, the user 102 can position or otherwise mount the HMD 100 according to the user's preferences. For example, the user 102 can be provided with the ability to adjust the top member 112, the first cross member 122, and / or the second cross member 124 to secure the HMD 100 to the user 102 in multiple directions to accommodate different feels and positioning of the HMD 100 on the user 102.

[0083] The HMD 100 may include speakers to provide audio to the user 102. For example, the HMD 100 may include a first speaker 130 positioned adjacent to the left ear of the user 102 and a second speaker 132 positioned adjacent to the right ear of the user 102. Figure 1As shown, the first speaker 130 may be coupled to the first cross member 122, and the second speaker 132 may be coupled to the second cross member 124. In this way, when the first cross member 122 and the second cross member 124 are extended and / or retracted, the first speaker 130 and the second speaker 132 may move with the first cross member 122 and the second cross member 124, respectively. In addition, in some cases, the first speaker 130 and / or the second speaker 132 may be pivotally coupled to the first cross member 122 and the second cross member 124, respectively, to position the first speaker 130 and the second speaker 132 near the left ear and the right ear of the user 102, respectively (Y axis).

[0084] As described above, a computing device such as a game controller may be associated with the HMD 100 and may provide image data content to be presented on the display 108. Additionally or alternatively, the user 102 may operate a handheld controller associated with a content item displayed on the display 108. For example, the user 102 may grasp, hold, or grip a handheld controller, and such grasping may be associated with actions in the VR environment, such as dropping an object, grabbing an object, etc. In some cases, the display 108 may refresh the rate and present images on the display 108 based on data received from the handheld controller (e.g., proximity data indicating the grasp or hand position of the user 102). In order to communicatively couple the HMD 100 to the computing device and / or the handheld controller, the HMD 100 may include a network interface. The HMD 100 may be communicatively coupled to a network in any manner, such as through a global or local wired or wireless connection (e.g., a local area network (LAN), an intranet, Wi-Fi, Bluetooth, ZigBee, Z-Wave, etc.). Thus, the network may facilitate communications between computing devices, handheld controllers, and / or the HMD 100. For example, the front 104 of the HMD 100 may include a first wireless interface or first antenna 134, and the back 106 of the HMD 100 may include a second wireless interface and a second antenna disposed within the housing 128. In some cases, the HMD 100 may transmit signals or data via the first antenna 134 or the second antenna depending on which antenna is closest to or facing the computing device (e.g., a game controller).

[0085] The surface of the HMD 100 that contacts the user 102 may be filled with padding and have a large enough area to comfortably distribute the compressive force. Additionally or alternatively, the portion of the HMD 100 that contacts the user 102 may be shaped and / or contoured for ergonomic conformity to the head. For example, because the first end 126 of the first cross member 122 and the first end of the second cross member 124 may be close to the face of the user 102, or may potentially contact the face of the user 102, the first cross member 122 and / or the second cross member 124 may include padding or other padding. However, other portions of the HMD 100 may also include padding or other padding to increase the comfort of the HMD 100.

[0086] Figure 2 A rear perspective view of HMD 100 worn by user 102 is shown. Figure 1 As discussed, the top member 112 can be operably coupled to the top actuator 120 and help secure the HMD 100 to the user 102. For example, the top member 112 can be disposed on or above the top of the HMD 100 or the user 102 (e.g., the crown). The second end 200 of the top member 112 can extend into the jacket 116 (Z direction). Figure 2 As shown, the slot 118 can engage with the top actuator 120 to tighten and loosen the HMD 100 to the user 102. That is, the top actuator 120 can be engaged at different positions of the top member 112 via engagement with the slot. Actuating the top actuator 120 can change the exposed length of the top member 112 outside the jacket 116, thereby tightening and loosening the HMD 100 to the user 102. In addition, as discussed above, although Figure 2 The slot 118 is shown to be disposed on the outside of the jacket 116, but in some cases, the slot 118 can be constructed and / or positioned on the top member 112 so that the slot 118 between the fully extended state and the fully retracted state from the jacket 116 to the top member 112 is disposed on the inside of the jacket 116. In this way, hair can be prevented from being entangled with the slot 118 and / or the top actuator. Additionally or alternatively, the slot 118 can engage with the top actuator 120 at a location closer to the rear portion 106 of the HMD 100. In doing so, the slot 118 can remain within the jacket 116 between the fully retracted state and the fully extended state.

[0087] like Figure 2 As shown, first and second cross members 122, 124 extend from front 104 of HMD 100 to rear 106 of HMD 100. First and second cross members 122, 124 may be operably coupled to rear actuator 202 to help secure HMD 100 to user 102.

[0088] The rear actuator 202 may be attached, mounted, or otherwise coupled to the housing 128. A first portion of the rear actuator 202 may extend to the exterior of the housing 128 to be grasped by the user 102, while a second portion of the rear actuator 202 may be disposed within or within the interior of the housing 128 to operably engage the first and second cross members 122, 124. For example, a second end of the first and second cross members 122, 124 may be routed through the housing 128, respectively, to operably engage the first and second cross members 122, 124 with the rear actuator 202. As discussed above, the rear actuator 202 may include teeth, gears, pinions, or sprockets that engage with slots of the first and second cross members 122, 124, respectively. In doing so, the rear actuator 202 may cooperate with the first and second cross members 122, 124 at different locations of or along the first and second cross members.

[0089] In some cases, the housing 128 may include a transverse arm or other member into which the first cross member 122 and / or the second cross member 124 extend. For example, the housing 128 may include a receiver or channel to receive the first cross member 122 and / or the second cross member 124. For example, the housing 128 may include a passage, slot, or channel through which the first cross member 122 and the second cross member 124 (e.g., their second ends) extend. When the rear actuator 202 is actuated, the first cross member 122 and the second cross member 124 can extend into the housing 128 and retract back from the housing to tighten and loosen the HMD 100 to the user 102.

[0090] To allow the jacket 116 to flex, pivot, or rotate, the jacket 116 may be pivotably or rotatably coupled to the housing 128 via a hinge 204. In some cases, the hinge 204 may include a mechanical structure (i.e., a knuckle and pin) or may include other structures such as a piece of fabric or material that allows the jacket 116 to flex or rotate in the X, Y, and / or Z directions.

[0091] Figure 2 Also shown is a second speaker 132 coupled to the second cross member 124 .

[0092] Figure 3 A top view of HMD 100 is shown. In some cases, top actuator 120 and rear actuator 202 can be centrally aligned with each other (Z-axis) and / or centrally aligned on HMD 100.

[0093] The HMD 100 may include a rear strap 300 for clamping, gripping, or otherwise engaging the back of the user's 102 head. When the HMD 100 is worn by the user 102, the rear strap 300 may extend circumferentially or radially (in the X direction) around at least a portion of the back of the user's 102 head. For example, the rear strap 300 may engage the side and / or back of the user's 102 head. In some cases, the rear strap 300 may include features, contours, and / or structures corresponding to the ergonomic shape of the user 102. The rear strap 300 may also be configured to flex at certain points and / or locations to abut against the user's 102 head and secure the HMD 100. In some cases, the rear strap 300 may include a first portion 302 and a second portion 304, wherein the first portion is designed to engage the user's 102 head above the occipital lobe and the second portion is designed to engage the user's 102 head below the occipital lobe. The first portion 302 and / or the second portion 304 may include padding or other materials to increase user comfort.

[0094] First cross member 122 and second cross member 124 are shown extending between front 104 and rear 106 of HMD 100. In some cases, first cross member 122 and / or second cross member 124 may include multiple parts, portions, or sections. For example, first cross member 122 may include first section 306 that hingedly, rotatably, or pivotally couples first cross member 122 to display 108. Second section 308 may couple first section 306 or otherwise extend from first section toward rear 106 of HMD 100 (Z direction). In some cases, first section 306 may include a rigid section for providing structural support, while second section 308 may include a flexible portion or a semi-rigid portion that bends toward rear 106 of HMD 100. As shown in FIG. Figure 3 As shown, the second section 308 may extend to, across, adjacent to, or along the rear strap 300 toward the rear actuator 202. In some cases, the rear strap 300 (such as the first section 302) may include a channel, surface, or passageway for the first cross member 122 (or its end) to extend into and / or along. As described above, the rear actuator 202 may engage the first cross member 122, such as a slot included on or in the second section 308 of the first cross member 122, and the second section 308 may be curved, bent, or otherwise bent through or along the rear strap 300 to engage the rear actuator 202. In some cases, the first cross member 122 may extend along or into one or more of the first portion 302 and / or the housing 128.

[0095] Similarly, second cross member 124 may include a first section 310 that articulately, rotatably, or pivotally couples second cross member 124 to display 108. Second section 312 may couple first section 310 or otherwise extend from first section 310 toward rear 106 of HMD 100. In some cases, first section 310 may include a rigid section for providing structural support, while second section 312 may include a flexible or semi-rigid section that bends toward rear 106 of HMD 100. Figure 3 As shown, the second section 312 may extend to, across, adjacent to, or along the rear strap 300 toward the rear actuator 202. As such, in some cases, the rear strap 300 (such as the first section 302) may include a channel, surface, or passageway for the second cross member 124 (or an end thereof) to extend. The rear actuator 202 may engage the second cross member 124, such as including a slot on the second section 312. The second section 312 may be curved, bent, or otherwise curved through the rear strap 300 and / or the housing 128, or along the rear strap and / or the housing to engage the rear actuator 202.

[0096] The top member 112 may also extend between the front 104 and the back 106 of the HMD 100. The HMD 100 may include a top pad 314 located below the jacket 116 and the top member 112 (in the Y direction). Additionally, the top pad 314 may be sized to be larger than the width of the jacket 116 and / or the top member 112 (in the X direction). The top pad 314 may provide a cushioning effect between the jacket 116 and the user 102 and / or between the top member 112 and the user 102. The top pad 314 may also prevent the hair of the user 102 from becoming tangled with the slots 118 and / or the top actuator 120.

[0097] The HMD 100 may include a facial cushion 316 coupled to the display 108. The facial cushion 316 may be optimized to match the ergonomics of the user 102 to wrap around the front of the user's 102 head and seal against the user's 102 face. When the HMD 100 is secured to the user 102, the facial cushion 316 may prevent light or may substantially prevent light from penetrating into the interior of the display 108. For example, the facial cushion 316 may include a deformable material (e.g., foam) that conforms to the shape of the user 102. The facial cushion 316 may also include a nasal recessed area that may help place or position the HMD 100 relative to the user's 102 eyes.

[0098] Figure 4 1 shows a bottom view of the HMD 100. Figure 3As discussed, the first cross member 122 and the second cross member 124 may traverse a passage within the rear tether 300 to extend toward the rear actuator 202 and engage the rear brake. Figure 4 As shown, the rear strap 300 may include a first channel 400 disposed on a first side (e.g., the left side) of the HMD 100 and a second channel 402 disposed on a second side (e.g., the right side) of the HMD 100. The first channel 400 and the second channel 402 may help to respectively plan the routes of the first cross member 122 and the second cross member 124 to engage with the rear actuator 202. For example, in some cases, the second section 308 of the first cross member 122 may extend into the first channel 400, and the second section 312 of the second cross member 124 may extend into the second channel 402. Thus, after actuation, the actuator 202 may engage the first cross member 122 and the second cross member 124 at different positions or lengths to advance the front portion 104 and the rear portion 106 of the HMD 100 in the Z direction and tighten the HMD 100 to the user 102. In other words, when tightened, the distance between the first section 306 of the first cross member 122 and the entrance to the first channel 400 may decrease, while the distance between the first section 310 of the second cross member 124 and the entrance to the second channel 402 may decrease. Actuating the rear actuator 202 in different directions may cause the second section 308 of the first cross member 122 and the second section 312 of the second cross member 124 to extend from the first channel 400 and the second channel 402, respectively, to loosen the HMD 100.

[0099] Figure 5 100. A first section 306 of the first cross member 122 may be coupled to the display 108, and a second section 308 of the first cross member 122 may extend from the first section 306 toward the rear 106 of the HMD 100. As described above, the second section 308 of the first cross member 122 may include a semi-rigid material or a flexible material to bend or flex around the rear of the head of the user 102 and engage the rear actuator 202, thereby allowing the first cross member 122 to be adjusted in length via the rear actuator 202. In some cases, the second section 308 may extend into the first channel 400, or adjacent to the rear strap 300. For example, Figure 5 The second section 308 of the first cross member 122 extending into the first channel 400 and toward the rear actuator 202 is shown in phantom. Similarly, the second section 312 of the second cross member 124 may include a semi-rigid material or a flexible material to bend or flex around the back of the user's 102 head, thereby allowing the second cross member 124 to adjust in length when the rear actuator 202 is actuated. In some cases, the second section 312 may extend into the second channel 402, or adjacent to the rear strap 300. For example, Figure 5 The second section 312 of the second cross member 124 extending into the second channel 402 and toward the rear actuator 202 is shown in phantom.

[0100] Figure 5 A top pad 314 is shown disposed below the top member 112 and / or jacket 116 (e.g., in the Y direction) to rest on the head of the user 102 when the HMD 100 is worn by the user 102. In some cases, the top member 112 can be coupled to the front 104 of the HMD 100 via the structure of the first antenna 134 and / or a slot can extend through the structure of the first antenna 134.

[0101] Figure 6 A front view of HMD 100 is shown showing top member 112 extending between front portion 104 and rear portion 106 of HMD 100 and into jacket 116 to engage top actuator 120, thereby allowing length adjustment and extension of top member 112 into and retraction from jacket 116. In some cases, top member 112 can be centrally aligned on HMD 100.

[0102] Figure 7 A rear view of the HMD 100 is shown, showing the first cross member 122 and the second cross member 124 extending into or disposed within the housing. For example, as discussed above, the first cross member 122 and the second cross member 124 may include ends or portions (e.g., of their lengths) that engage the rear actuator 202. Figure 7 As shown, the first cross member 122 may include a second end 700 opposite the first end 126, the first end being coupled to the display 108. The second end 700 may represent an end or portion of the second section 308 of the first cross member 122 that engages the rear actuator 202. As described above, the first cross member 122 may include a slot 702 disposed adjacent to the second end 700 of the first cross member 122 and / or disposed along a length of the first cross member 122 proximate to the second end 700. The slot 702 may be complementary to engage with a mechanism of the rear actuator 202.

[0103] Similarly, the second cross member 124 can include a second end 704. The second end 704 can be opposite the first section 310 coupled to the display 108. The second end 704 can represent the end of the second section 312 of the second cross member 124 that engages the rear actuator 202. The second cross member 124 can include a slot 706 disposed adjacent to the second end 704 of the second cross member 124 and / or disposed along a length of the second cross member 124 proximate to the second end 704. The slot 706 can be complementary to engage with a mechanism of the rear actuator 202.

[0104] like Figure 7 As shown, at the rear portion 106 of the HMD 100, such as within the housing 128, the first cross member 122 and the second cross member 124 may cross or overlap. When actuated, the second end of the first cross member 122 and the second end of the second cross member 124 (i.e., 700 and 704) may traverse in the X direction. For example, when tightened, the first cross member 122 and the second cross member 124 may extend through the rear actuator 202. As a result, the second end of the first cross member 122 and the second end of the second cross member 124 may extend further away from each other (X direction). When loosened, the first cross member 122 and the second cross member 124 may extend back through the rear actuator 202, and the second end of the first cross member 122 and the second end of the second cross member 124 may move closer to each other (X direction). Rotating the rear actuator 202 in one direction will increase the overlapping relationship of the second end 700 and the second end 704, while rotating the rear actuator 202 in the opposite direction will reduce the overlapping relationship. In this manner, the first cross member 122 and the second cross member 124 may form a closed loop whose length is adjustable to accommodate a variety of different head sizes.

[0105] First cross member 122 and second cross member 124 may extend and retract in unison. That is, when first cross member 122 and second cross member 124 are engaged with rear actuator 202, first cross member 122 and second cross member 124 may extend and retract simultaneously and by the same amount.

[0106] In some cases, first cross member 122 and second cross member 124 may engage rear actuator 202 at any location (in the X direction) within housing 128 and / or rear strap 300. For example, first cross member 122 and second cross member 124 may engage rear actuator 202 at a location close to or adjacent to rear strap 300 and spaced apart from rear portion 106 of HMD 100 in the Z direction. In some cases, first cross member 122 and second cross member 124 may engage rear actuator 202 at a location close to or adjacent to rear portion 106 of HMD 100 (such as beneath an outer cover of housing 128 at rear portion 106 of HMD 100).

[0107] Fig. 8A and Figure 8B A detailed cross-sectional view showing the engagement between the top member 112 and the top actuator 120 is shown. The top member 112 extends (in the Z direction) into the jacket 116 to operably engage the top actuator 120. For example, as shown in FIG. Figure 8BAs shown, the top member 112 includes a slot 118 that engages with the top actuator 120. Although the slot 118 is shown as a series of teeth extending longitudinally (Z direction) along at least a portion of the length of the top member 112, the slot 118 may include any concave mechanism / convex mechanism to engage with a corresponding convex mechanism / concave mechanism of the top actuator 120. For example, the slot 118 may be similar to a detent, a lip, a buckle, a flexure, a friction coupling, a clip, a latch, a snap, etc. The top actuator 120 can be rotated (about the Y axis) to shorten and lengthen the length of the top member 112 exposed or disposed outside the jacket 116 to tighten and loosen the top member 112. As described above, in order to accommodate and / or receive the top member 112, the jacket 116 includes a channel or passage that allows the top member 112 to extend into and out of the jacket 116 (Z direction). Furthermore, the first cross member 122 and / or the second cross member 124 may include similar features and may similarly engage the rear actuator 202 .

[0108] Fig. 9 A perspective view of wire routing portion 900 is shown. In some cases, wire routing portion 900 can be used to route one or more wires, cables, strings, or optical fibers between different portions of an HMD. For example, wire routing portion 900 can route one or more wires between a front portion of an HMD (such as front portion 104 of HMD 100) and a rear portion of the HMD (such as rear portion 106 of HMD 100).

[0109] The wire routing portion 900 may include a housing 902 extending between a first end 904 and a second end 906. Between the first end 904 and the second end 906, the housing 902 may be arcuate (similar to a hemispherical, semicircular, and / or semi-cylindrical shape) and is designed to extend over the top or crown of the user's head.

[0110] The slide 908 is operably engaged with or within the housing 902 and is allowed to extend and retract from the housing 902 at different lengths. As an example, the housing 902 may be similar to a collet in which the slide 908 may be telescopically extended and retracted. In some cases, Fig. 9The wire routing portion 900 is shown in a withdrawn or retracted state or a partially retracted state. When in the retracted state, the first end 910 of the slider 908 may extend (in the Z direction) from the first end 904 of the housing 902 so as to protrude from the interior or channel of the housing 902 and be exposed to the outside of the housing 902. However, in some cases, the slider 908 may be configured to be completely folded within the interior of the housing 902 or extend within the interior of the housing when in the retracted state. For example, when transitioning to the extended state, the first end 910 of the slider 908 may be extended (in the Z direction) and extend from the housing 902 to protrude outward from the housing 902. In other words, when in the extended state or the partially extended state, the first end 910 of the slider 908 may protrude from the first end 904 of the housing 902 more than when in the retracted state. Fig. 9 The larger distances shown in .

[0111] In some cases, the slide 908 may include a similar profile, geometry, arc, and structure as the housing 902 to allow the slide 908 to extend from and retract within the housing 902. In doing so, the housing 902 and the slide 908 may form a convenient mechanism to extend the length of the wire routing portion 900.

[0112] As described above, wire routing portion 900 may extend between portions of an HMD. In some cases, wire routing portion 900 may include wires that communicatively couple computing components located at the front of the HMD to computing components located at the back of the HMD. For example, Fig. 9 As shown, the slider 908 includes a wire 912 that protrudes or extends from a first end 910 of the slider 908. In some cases, the wire 912 may be partially disposed within the slider 908 (e.g., embedded therein) and / or may extend along one or more surfaces of the slider 908 and be connected to one or more surfaces of the slider. As will be discussed herein, the wire 912 may extend from the first end 910 of the slider 908 through the housing 902 and to the second end 906 of the housing 902 to communicatively couple the front and rear of the HMD. As an example, the wire 912 may communicatively couple an antenna located at the front of the HMD (e.g., the first antenna 134 of the HMD 100) with an antenna located at the rear of the HMD. In other examples, the wire 912 may provide power to a display of the HMD (e.g., the display 108 of the HMD 100), or may provide a signal or data to render a content item of the display. Although Fig. 9 The wire routing portion 900 or slide 908 may be shown as including a single wire, but in some cases, the wire routing portion 900 may include more than one wire, or may include a bundle of wires extending between a first end 910 of the slide 908 and a second end 906 of the housing 902.

[0113] Fig.10 A front view of the wire routing portion 900 is shown. In some cases, the wire routing portion 900 may include two portions that are abutted, attached, or coupled via a fastener 1000 (e.g., a screw, rivet, bolt, pin, etc.). For example, the housing 902 may include two halves coupled by the fastener 1000. When coupled together, the housing 902 may form a channel within which the slide 908 may telescopically extend from the first end 904 of the housing 902. However, the wire routing portion 900 and / or the housing 902 may include a plurality of portions that are coupled to the housing 902. Fig.10 Different shapes, contours or arcs are shown and / or fastener 1000 may be omitted. As an example, wire routing portion 900 may include two halves that snap fit together and may have a smooth outer contour and perimeter without notches, bumps and / or protrusions.

[0114] Fig.11A and Fig. 11B An end view of the wire routing portion 900 is shown. Specifically, Fig.11A A view of a first end 904 of the housing 902 is shown, and Fig. 11B A view of the second end 906 of the housing 902 is shown.

[0115] The first end 904 of the housing 902 may include a first opening 1100 through which the slide 908 may extend. Fig.11A As shown, the slider 908 can extend out of the first end 904 of the housing 902. The second end 906 of the housing 902 can include a second opening 1102. Disposed between the first opening 1100 and the second opening 1102 can be a channel 1104. The channel 1104 can pass between the first end 904 and the second end 906 of the housing 902.

[0116] The channel 1104 can provide a passage or pathway for the slider 908 within the housing 902. For example, the channel 1104 can allow the slider 908 to telescopically engage the housing 902 as the slider 908 extends from the housing 902 and retracts within the housing.

[0117] In some cases, the channel 1104, the surface of the channel 1104, and / or the inner surface of the housing 902 may include protrusions, ribs, or other struts to secure or position the slider 908 within the housing 902 and / or the channel 1104. For example, the channel 1104 may include a rib 1106 disposed on the top of the channel 1104 and extending between the first end 904 (or the first opening 1100) of the housing 902 and the second end 906 (or the second opening 1102) of the housing 902. The rib 1106 may abut, contact, or operably provide a surface on which the slider 908 may move.

[0118] The ribs 1106 can also bias the slider 908 away from contacting the inner surface of the channel 1104. In some cases, the ribs 1106 can bias the slider from the inner surface of the channel 1104 to provide an area through which one or more wires can extend. Such biasing can prevent the wires from interfering with or preventing movement of the slider 908 within the housing 902 and / or within the channel 1104.

[0119] As discussed above, the wire 912 may be routed from the first end 910 (eg, Fig.11A ) extends to the second end 906 of the housing 902 (as shown Fig. 11B That is, the first end of the wire 912 can be disposed at the first end 910 of the slider 908, and the second end of the wire 912 can be disposed at the second end 906 of the housing 902. In this way, the wire 912 can traverse the slider 908, the housing 902, and the channel 1104 between the first end 910 of the slider 908 and the second end 906 of the housing 902.

[0120] In some cases, portions of the wire 912 may be coupled to or integrated with the slider 908 such that the wire 912 lengthens or extends and retracts or retracts with movement of the slider 908. For example, portions of the wire 912 may be routed through the slider 908, may extend through a channel or passageway of the slider 908, may be coupled to an outer surface of the slider 908, and / or may be embedded within the slider 908. In doing so, the wire 912 may remain coupled to the slider 908 as the slider 908 extends from and retracts within the housing 902.

[0121] The housing 902 may include an elongated slot 1108 through which a portion of the wire 912 extends. In some cases, the elongated slot 1108 may extend from the second end 906 of the housing 902 or the second opening 1102 toward the interior of the housing 902 or the first end 904 of the housing 902 (the Z direction). The elongated slot 1108 may be sized and configured to receive at least a portion of the wire 912. For example, Fig. 11B As shown, the elongated slot 1108 may include a conduit through which a portion of the wire 912 may extend.

[0122] As described above, the wire 912 can be configured to elongate as the slider 908 extends from the housing 902, and to retract as the slider 908 retracts within the housing 902. In some cases, a first portion of the wire 912 can be routed through with the slider 908, a second portion of the wire 912 can be routed within the elongated slot 1108, and a third portion between the first portion and the second portion can be coiled, looped, meandered, or routed within the channel 1104. The third portion can provide a slack portion that allows the slider 908 to operably extend from the housing 902 at various lengths while also allowing the slider 908 to be folded within the housing 902 or retracted within the housing. For example, because the wire routing portion 900 can be integrated with an HMD, the slack portion allows the slider 908 to extend from the housing 902 to adjust to the wire routing portion 900 for different head sizes of a user wearing the HMD.

[0123] Fig. 12A and Fig. 12B The engagement between the housing 902 and the slide 908 is shown. Fig. 12A and Fig. 12B In some cases, the housing 902 is shown as semi-transparent to illustrate the operation of the slide 908 within the housing 902 (such as within the channel 1104 of the housing 902). Fig. 12A The wire routing portion 900 is shown in a retracted or partially retracted state, and Fig. 12B The wire routing portion 900 is shown in an extended state or in a partially extended state. That is, in the extended state, the first end 910 of the slider 908 can extend further from the first end 904 of the housing 902 than in the retracted state, so that the slider 908 is exposed to a longer length outside the housing 902.

[0124] like Fig. 12A As shown, in the retracted state, the slider 908 can minimally protrude or extend (in the Y direction and the Z direction) from the housing 902. For example, the first end 910 of the slider 908 can protrude from the first end 904 of the housing 902. The second end 1200 of the slider 908 opposite the first end 910 is shown to be disposed within the housing 902, closer to the second end 906 of the housing 902 in the channel 1104, when in the retracted state.

[0125] In some cases, the housing 902, the slider 908, and / or the channel 1104 may include features, such as flanges or stops, that the second end 1200 of the slider 908 abuts when in the retracted state. As such, in some cases, the slider 908 may be prevented from fully extending into the housing 902. In other cases, when in the retracted state, the second end 1200 of the slider 908 may abut against a stop such that the first end 910 of the slider 908 extends from the housing 902 or such that the first end 910 of the slider 908 is substantially planar or aligned with the first end 904 of the housing 902.

[0126] When in the retracted state, Fig. 12A It is shown that the wire 912 can be routed from the first end 910 of the slider 908 (inside the housing 902 or in the channel 1104) to the second end 906 of the housing 902. The housing 902 can include a conduit (e.g., an elongated slot 1108) for receiving the wire 912 (or a portion of the wire 912) and routing the wire 912 from the first end 910 of the slider 908 to the second end 906 of the housing 902. In some cases, such as Fig. 12A and Fig. 12B As shown, the wire 912 can be routed from a first side (e.g., right side) of the wire routing portion 900 to a second side (e.g., left side) of the wire routing portion 900. Such routing can prevent the wire 912 from bending or curling when the slider 908 transitions between the retracted state and the extended state. In some cases, the stiffness of the wire 912 or the thickness of the wire 912 can prevent the wire 912 from bending.

[0127] Back to About Fig.11A and Fig. 11B As discussed above, in some cases, a first portion 1202 of the wire 912 may be attached, embedded within, or coupled to the slider 908. The first portion 1202 of the wire 912 may extend from the first end 910 of the slider 908 and along the longitudinal direction (Z direction) of the slider 908 toward the second end 1200 of the slider 908. A second portion 1204 of the wire 912, opposite the first portion 1202, may extend from the second end 906 of the housing 902 and toward the first end 904 of the housing 902 within the elongated slot 1108. A third portion 1206 of the wire 912 may extend between the first portion 1202 and the second portion 1204 and may provide slack for the slider 908 to extend from the housing 902. In other words, the third portion 1206 of the wire 912 may extend from the second end 1200 of the slider 908 to a location where the wire 912 engages the elongated slot 1108. Between these two locations, or between the first portion 1202 and the second portion 1204 of the wire 912, such as Fig. 12AAs shown, the wire 912 can be coiled or curled within the housing 902 and / or within the channel 1104. Thus, when the wire routing portion 900 transitions between the retracted state to the extended state, the third portion 1206 can provide excess wire to allow the slider 908 to extend from the housing 902.

[0128] Steering Fig. 12B , when in the extended state, the slider 908 can extend or protrude from the housing 902 (in the Y direction and the Z direction). In some cases, the slider 908 can be telescopically extended from the first end 904 of the housing 902. When in the extended state, the first end 910 of the slider 908 can protrude from the first end 904 of the housing 902 a longer distance than the distance that the first end 910 of the slider 908 protrudes from the first end 904 of the housing 902 when in the retracted state. In other words, when in the extended state, the second end 1200 of the slider 908 can be set at a farther distance from the second end 906 of the housing 902 than when in the retracted state. As shown in FIG. Fig. 12B As shown, the third portion 1206 can provide slack for the extension of the slide 908 accordingly. Fig. 12B In the embodiment of the present invention, the third portion 1206 is extended or lengthened to allow the slider 908 to extend to the extended state. The wire 912 may have sufficient slack, or the third portion 1206 may include sufficient length to accommodate the slider 908 extending from the housing 902.

[0129] In some cases, the slider 908 and / or the housing 902 may include features, such as tabs, flanges, or stops, that prevent the slider 908 from disengaging from the housing 902 when in the extended state. Thus, these stops may prevent the slider 908 from completely leaving the channel 1104 and becoming uncoupled from the housing 902.

[0130] Fig.13 A side view of the wire routing portion 900 is shown, showing the wire routing portion 900 in an extended or partially extended state. A first end 910 of the slider 908 is shown extending from the first end 904 of the housing 902.

[0131] The housing 902 and slide 908 may be arcuate, curved, and / or include similar arcs or lengths to allow the slide 908 to extend from the housing 902 and retract within the housing.

[0132] Fig.141400. In some cases, HMD 1400 may include similar components or features as HMD 100. For example, HMD 1400 may include a display, structures for adjusting and accommodating different head sizes, speakers for outputting audio to a user wearing HMD 1400, and the like. However, as Fig.14 As shown, HMD 1400 includes a wire routing portion 1402 for routing one or more wires between a front portion 1404 of HMD 1400 and a rear portion 1406 of HMD 1400. In some cases, wire routing portion 1402 may be similar to, represent, or include features similar to wire routing portion 900. For example, wire routing portion 1402 may include a housing 1408 and a slider 1410 that is operable to telescopically extend from housing 1408 at different lengths.

[0133] Wire routing portion 1402 may be disposed below top member 1412 and jacket 1414 (in the Y direction). In some cases, housing 1408 and jacket 1414 may be attached to or coupled to each other. Top member 1412 may be similar to and / or represent top member 112, and may be adjustable in length to extend and retract to accommodate different users wearing HMD 100 and / or to accommodate different tightness for users. For example, top member 1412 may include slot 1416 engaged with top actuator 1418. Top actuator 1418 may be coupled to jacket 1414 having an opening, and allow top member 1412 to extend from the opening and retract within the opening. In doing so, top member 1412 may be adjustable in length.

[0134] The wire routing portion 1402 is configured to extend and retract as the top member 1412 is adjusted. Therefore, when the top actuator 1418 is actuated, the wire routing portion 1402 can be adjusted to accommodate different users. When the top member 1412 extends from the jacket 1414 to increase the length, the length of the wire routing portion 1402 can be increased accordingly. For example, when the top member 1412 extends from the jacket 1420, the length of the slider 1410 extending from the housing 1408 can be increased. Accordingly, when the top member 1412 extends into the jacket 1420 to reduce the length, the length of the wire 1402 can be reduced accordingly. For example, when the top member 1412 extends into the jacket 1414, the length of the slider 1410 extending from the housing 1408 can be reduced and retracted within the housing 1408.

[0135] The top actuator 1418 can drive the slide 1410 from the housing 1408 and retract the slide into the housing. For example, when the top member 1412 is operably coupled to the front portion 1404 of the HMD 1400 and the rear portion 1406 of the HMD 1400 via the jacket 1414, when the top actuator 1418 is actuated, the front portion 1404 of the HMD 1400 and the rear portion 1406 of the HMD 1400 can extend and separate (Z direction) or retract together (Z direction). The movement of the front portion 1404 and the rear portion 1406 of the HMD 1400 can cause the slide 1410 to extend from the housing 1408 and retract within the housing 1408 accordingly.

[0136] In some cases, housing 1408 and jacket 1414 may comprise similar lengths and / or may extend from rear portion 1406 of HMD 1400 a similar distance.

[0137] The wires routed through the wire routing portion 1402 may include sufficient slack to allow the slider 1410 to extend from and retract within the housing 1408. In this way, the wires may move within the housing 1408 to allow the slider 1410 to extend. For example, the wire routing portion 1402 (such as the housing 1408) may include a channel to route the wires between the front 1404 and the back 1406 of the HMD 1400 and / or to help or prevent the wires from snagging, bending, or curling within the housing 1408 as the slider 1410 telescopically extends from and into the housing.

[0138] In some cases, routing wires through the wire routing portion 1402 can avoid routing or positioning wires along the sides of the HMD 1400, which can increase the aesthetic appearance of the HMD 1400 and / or prevent cables and / or parts of the user (e.g., hair) from getting caught or tangled with the wires. In other words, for example, rerouting cables or other wires between parts of the head-mounted display can facilitate free movement of the user and / or reduce external clutter on the sides of the head-mounted display. In some cases, the wire routing portion 1402 can be configured to route a single wire, multiple wires, a chord, and / or a bundle of wires. For example, the wire routing portion 1402 may include a first wire, a second wire, and / or a third wire, wherein the first wire is used to power a display at the front 1404 of the HMD 1400, the second wire is used to communicatively link an antenna of the HMD 1400, and the third wire is used to provide image data for output on the display of the HMD 1400. However, in some cases, the HMD 1400 may additionally or alternatively include wires routed along the HMD 1400 for communicatively coupling components at the front 1404 of the HMD 1400 with components at the back 1406 of the HMD 1400 .

[0139] Fig.15 A top view of HMD 1400 is shown. Fig.15 14, portions of the top member 1412 and jacket 1414 are shown as semi-transparent to show the wires 1500 routed from the front 1404 of the HMD 1400 to the back 1406 of the HMD 1400. The wires 1500 are generally represented by the dashed lines in the wire routing portion 1402.

[0140] As shown, the wires 1500 may be routed from a first end 1502 of the slider 1410 along the longitudinal length (Z direction) of the slider 1410 to a rear portion 1406 of the HMD 1400 to one or more components disposed in a compartment or housing at the rear portion 1406 of the HMD 1400. A second end may be disposed within the housing 1408.

[0141] The first end 1502 of the slider 1410 or the first end of the top member 1412 can be hingedly, rotatably or pivotally coupled to the HMD 1400 to allow adjustment of the display on the user's face. In some cases, the wire 1500 can be routed along the first side 1504 of the wire routing portion 1402 within the slider 1410 and transition to be routed through the housing 1408 along the second side 1506 of the wire routing portion 1402 (i.e., spaced apart from the first side 1504 in the X direction). The wire routing portion 1402 may include a channel on the corresponding side or a component of the wire routing portion 1402 for receiving and routing the wire 1500.

[0142] Fig.16 A side view of head mounted display (HMD) 1600 is shown. In some cases, HMD 1600 may include similar components as HMD 100 and / or HMD 1400. For example, HMD 1600 may include members and actuators for adjusting the size of HMD 1600 when worn by a user, and may include a wire routing portion, such as wire routing portion 900 or wire routing portion 1402 for routing wires between front portion 1602 and rear portion 1604 of HMD 1600.

[0143] The HMD 1600 may include a strap 1606 disposed at the rear 1604 of the HMD 1600 that adjusts and / or conforms to various users. The strap 1606 may be centrally aligned with the longitudinal axis (Z direction) of the HMD 1600 to clamp the center of the back of the user's head. That is, when the HMD 1600 is worn by the user, the strap 1606 may pivot and centrally hold, grab or clamp the back of the user's head. The strap 1606 may also be spring loaded (e.g., a coil spring, a torsion spring, a conical spring, etc.) or tension loaded to extend and maintain contact with the back of the user's head. The strap 1606 may also be flexed around one or more axes to conform to the back of the head.

[0144] In some cases, the strap 1606 may include a frame 1608 that is pivotally coupled to the housing 1610 at the rear 1604 of the HMD 1600. In some cases, the frame 1608 may be coupled to the housing 1610 via a first hinge 1612, a strut 1614, and / or a second hinge 1616. The first hinge 1612 may be coupled to a first end of the strut 1614 and allow the strut 1614 to translate in horizontal and vertical directions toward the front 1602 and top of the HMD 1600 (Y direction and Z direction). The strut 1614 may pivot about the first hinge 1612 to move outward or extend away from the housing 1610 toward the user, and / or may pivot about the first hinge 1612 (X axis) to move inward or toward the housing 1610 (Z direction). In doing so, the strap 1606 may be positioned horizontally and vertically to clamp the back of the head. The support rod 1614 can be centrally aligned with the longitudinal axis (Z direction) of the HMD 1600.

[0145] In addition, the frame 1608 can pivot about the second hinge 1616 (X axis) to further help clamp the back of the head. For example, the second hinge 1616 can be connected to the second end of the strut 1614 and can allow the frame 1608 to be repositioned below the occipital lobe and / or clamp the occipital lobe. In doing so, when secured to the user, the strap 1606 can provide stability and lock the HMD 1600 below the base of the head to prevent movement of the HMD 1600 (e.g., when the head is tilted). In addition, the frame 1608 can be centrally aligned with the longitudinal axis (Z direction) of the HMD 1600 to be connected to the back of the head.

[0146] As discussed herein, the strap 1606 may have a spring (e.g., a coil spring, a torsion spring, a conical spring, etc.), a shape, a certain material thickness, and / or other biasing member to apply a constant pressure or force to the back of the head. For example, the strap 1606 may include a spring 1618 (e.g., a torsion spring, a leaf spring, etc.) disposed between the strut 1614 and the housing 1610. The spring 1618 may be operably engaged with the strut 1614 to position the strut 1614 outward from the housing 1610 so as to abut the user's head. The spring 1618 may apply a force to the strut 1614 to translate the strut 1614 in the Z direction or toward the front 1602 of the HMD 1600. Additionally, in some cases, the spring 1618 may be disposed above the pin of the first hinge 1612 to bias the strut 1614 about the X-axis.

[0147] Because the strap 1606 is designed to clamp the back of the head, the strap 1606 may include a pad 1620 coupled to the frame 1608 to increase user comfort. In some cases, the strut 1614 may be hinged, rotatably or pivotally coupled to a first side of the frame 1608, and the pad 1620 may be coupled to a second side of the frame 1608 opposite the first side. In addition, the shape of the frame 1608 and / or the pad 1620 may be bent, curved, curved, or include other features and / or shapes to correspond to the ergonomics of the user. Additionally or alternatively, the strap 1606 may be coupled or coupled to the housing via a ball joint to articulate about one or more axes.

[0148] HMD 1600 may also include other structures to position and / or secure HMD 1600. For example, housing 1610 may include lateral supports 1622 configured to extend circumferentially or radially around a portion of a user's head. In some cases, lateral supports 1622 may include flanges or other protrusions that extend outward from the middle of HMD 1600 to engage left and right portions of the user's head. When HMD 1600 is tightened onto the user (e.g., via an adjustable top member and / or an adjustable cross member), lateral supports 1622 may distribute compressive forces across the head. The portion of lateral supports 1622 that contacts the head may include padding.

[0149] like Fig.16 As shown, the lateral support 1622 may be disposed above the strap 1606 (in the Y direction). In some cases, the lateral support 1622 may grip or clamp the back of the user's head at a position above the occipital lobe. Thus, the HMD 1600 may include a structure that clamps to the user's head below the occipital lobe (e.g., the strap 1606) and a structure that clamps to the user's head above the occipital lobe (e.g., the lateral support 1622).

[0150] Fig.17 16 shows a top perspective view of HMD 1600. As shown, strap 1606 extends from housing 1610 and in a direction (Z direction) toward front 1602 of HMD 1600. As discussed above, strap 1606 may be allowed to rotate and position to conform to and clamp to the user's occipital lobe via first hinge 1612, strut 1614, and second hinge 1616. In addition, Fig.17 It is shown that the strap 1606 may include a spring 1700 (or other biasing member) to maintain pressure or force on the user's head, which can further help secure the HMD 1600 to the user. The spring 1700 can be biased about the X-axis to clamp and / or position the frame 1608 under the occipital lobe.

[0151] When HMD 1600 is secured to a user, or when HMD 1600 is being secured to a user, first hinge 1612, strut 1614, second hinge 1616, spring 1618, and / or spring 1700 may be operated in concert to hold frame 1608 against the occipital lobe. That is, because the back of the head between users may include different shapes or ergonomics, strap 1606 may be positioned and adjusted to accommodate different users.

[0152] The strap 1606 may also be configured to operate in conjunction with components that increase or decrease the size of the HMD 1600 on the user. For example, the HMD 1600 may include a component that engages with an actuator and adjusts the length of the component. As an example, Fig.17 As shown, HMD 1600 may include member 1702 (which may represent and / or correspond to second transverse member 124) and actuator 1704 (which may represent and / or correspond to rear actuator 202). When HMD 1600 is tightened to the user via actuation of actuator 1704, member 1702 may be retracted within housing 1610 via channel 1706. When the front portion 1602 of HMD 1600 is pulled toward the rear portion 1604 of HMD 1600 (or vice versa), strap 1606 may be repositioned horizontally (Z direction) and vertically (Y direction) to engage the user's head.

[0153] Fig.18A top view of a strap 1606 of an HMD 1600 is shown, showing a frame 1608 operably coupled to a housing 1610 via a first hinge 1612, a strut 1614, a second hinge 1616, a spring 1618, and a spring 1700 (e.g., a torsion spring, a leaf spring, etc.). The frame 1608 may be curved, arcuate, or include other features and / or shapes to correspond to the ergonomics of the user (e.g., X-direction) so as to clamp to the head and / or radially wrap around at least a portion of the back of the head or extend circumferentially around at least a portion of the back of the head. For example, the frame 1608 may be semicircular, substantially semicircular, arcuate, or curved.

[0154] The frame 1608 may include a first portion that extends, expands, or bends in a first direction away from the longitudinal axis (Z axis) of the frame 1608 to clamp the right side of the back of the user's head. The frame 1608 may also include a second portion that extends, expands, or bends in a second direction away from the longitudinal axis of the frame 1608 to clamp the left side of the back of the user's head. In some cases, the frame 1608 may include a third portion that is between the first portion and the second portion, the third portion being planar to clamp the center portion of the back of the user's head.

[0155] As shown, the spring 1700 can bias the frame 1608 about the X-axis to maintain pressure on the head. For example, depending on the orientation of the spring 1700, the spring 1700 can bias the frame toward the top or bottom of the HMD 1600. Additionally, in some cases, the spring 1700 can be disposed above the pin of the second hinge 1616 to bias the frame 1608 about the X-axis.

[0156] The strap 1606 may include additional mechanisms to help position the strap 1606 around the user and / or increase user comfort. For example, Fig.18 It is shown that the frame 1608 may include a slot 1800. In some cases, the slot 1800 may be disposed on the back side (or first side) of the frame 1608, opposite the front side (or second side) of the frame 1608 including the pad 1620. The slots 1800 may extend in the height direction (Y direction) of the frame 1608 or in the direction from the bottom 1802 of the frame 1608 to the top 1804 of the frame, and may be spaced apart from each other in the width direction (X direction) of the frame 1608. The fasteners 1806 may extend through the mount 1808 to engage the slots 1800. For example, the fasteners 1806 may be disposed through the mount 1808 and coupled to the slots 1800 and / or the frame 1608. However, the fasteners 1806 may be loosened so that the frame 1608 may be repositioned along the slots 1800 (Y direction). Thus, additional degrees may be provided to the user to personalize the configuration of the HMD 1600.

[0157] Fig.19 A user 1900 is shown wearing the HMD 1600. As discussed above with respect to the HMD 100, the user 1900 may wear the HMD 1600 to immerse the user 1900 in a VR or AR environment.

[0158] The user 1900 may actuate one or more actuators of the HMD 1600 to secure and / or tighten the HMD 1600. For example, the user 1900 may actuate an actuator 1704 that is operably coupled to the member 1702. When the user 1900 actuates the actuator 1704 to tighten the HMD 1600, the rear portion 1604 and the front portion 1602 of the HMD 1600 may be directed inward (Z direction) to tighten the HMD 1600 to the user 1900. When tightened, the strap 1606 may engage the back of the head of the user 1900, as shown in FIG. Fig.19 That is, when HMD 1600 is tightened to user 1900, strap 1606 can be biased against the back of the user's 1900 head. As discussed above, strap 1606 can include hinges (e.g., first hinge 1612 and second hinge 1616) and struts (e.g., strut 1614) that allow strap 1606 to be repositioned laterally and vertically to accommodate user 1900. In this way, and as Fig.19 As shown, the strap 1606 may engage the back of the user's 1900 head below the occipital lobe.

[0159] Moving the actuator 1704 in the opposite direction reduces the force applied by the HMD 1600 and can allow the HMD 1600 to be loosened from the user 1900 and / or adjust the configuration of the HMD 1600. In doing so, and when loosened, the strap 1606 can remain in contact with the back of the user's 1900 head. That is, the inclusion of the spring 1618 and the spring 1700 allows the strap 1606 to maintain contact or pressure against the back of the user's 1900 head. As the user 1900 adjusts the HMD 1600 to change the force applied by the HMD 1600, the strap 1606 can be directed inward (i.e., Z direction, toward the user 1900, toward the front 1602) and directed outward (Z direction, away from the user 1900, toward the back 1604) and can be allowed to pivot (X axis) to clamp the head.

[0160] In addition, if Fig.19, when HMD 1600 is worn by user 1900, lateral support 1622 may extend circumferentially around at least a portion of the back of the head of user 1900 (such as the left and right sides of user 1900). In some cases, once HMD 1600 is worn by the user, strap 1606 or frame 1608 may be disposed inside (in the Z direction) of lateral support 1622.

[0161] Fig. 20 An exemplary strap 2000 is shown. In some cases, strap 2000 may be used with an HMD, such as HMD 100 and / or HMD 1400. Strap 2000 may be located at the back of the HMD to abut or clamp the back of the user's head, such as the occipital lobe. Fig. 20 As shown, the strap 2000 may include a strut 2002 extending from the rear of the HMD and engaging with a frame 2004 of the strap 2000 via a hinge 2006. The hinge 2006 may help position the frame 2004 against the back of the user's head. For example, the strap 2000 may apply a force to the back of the head just below the occipital lobe to provide stability and position the strap 2000 below the base of the head. In some cases, the frame 2004 may be spring loaded to conform to the user. Additionally or alternatively, the frame 2004 may be coupled to the strut 2002 via a ball joint for pivoting and allowing the frame 200 to abut against the user's head.

[0162] Fig.21A and Fig.21B A perspective view of the wire routing portion 2100 is shown. Fig.21A The wire routing portion 2100 is shown in a retracted or partially retracted state, and Fig.21B The wire routing portion 2100 is shown in an extended state or a partially extended state.

[0163] In some cases, wire routing portion 2100 may be similar to and / or include features similar to wire routing portion 900 and / or wire routing portion 1402. For example, wire routing portion 2100 may include a housing 2102, a slide 2104 that telescopically extends from a first end 2106 of housing 2102, and a wire 2108 that extends from a first end 2110 of slide 2104, through housing 2102, and to a second end 2112 of housing 2102. Fig.21B , the wire 2108 is generally represented by a dotted line to illustrate the wire 2108 being routed through the wire routing portion 2100.

[0164] In some cases, the wire routing portion 2100 may include an actuator 2114 that is operable to extend the slider 2104 at different lengths from the housing 2102. In some cases, the actuator 2114 may include features similar to the top actuator 120 discussed previously herein. The actuator 2114 may be disposed on or coupled to the housing 2102 and operably engage the slider 2104. For example, the actuator 2114 may include teeth that engage with the slots 2116 of the slider 2104. By actuating the actuator 2114, the slider 2104 may be adjusted in length and extend at different lengths from the first end 2106 of the housing 2102. For example, actuating the actuator 2114 may cause the slider 2104 to extend from the housing 2102 or retract within the housing, or may cause the slider 2104 to transition between an extended state or a retracted state. Thus, the engagement between the actuator 2114 and the slider 2104 can be similar to a ratchet mechanism that moves the slider 2104 in and out of the housing 2102. The housing 2102 can include a channel for receiving the slider 2104 when adjusting the length of the slider 2104.

[0165] As discussed above, the wire 2108 may include a sufficient amount of slack to allow the slider 2104 to telescopically extend into the housing 2102. In addition, the housing 2102 and / or the slider 2104 may include features that allow the wire 2108 to extend and retract without being caught, pinched, or bent. Thus, the user can operate the actuator 2114 to accommodate different head sizes or tightness.

[0166] Fig. 22 An HMD 2200 including a wire routing portion 2100 is shown being worn by a user 2202. In some cases, the HMD 2200 may represent, correspond to, or include features similar to the HMD 100, HMD 1400, and / or HMD 1600 discussed above herein. For example, the HMD 2200 may include one or more members that adjust in length to accommodate different head sizes of users and / or adjust the tightness of the HMD 2200 on the user 2202. The one or more members may span or extend between a front portion 2204 and a rear portion 2206 of the HMD 2200 and may engage or be operably coupled to one or more actuators.

[0167] like Fig. 22As shown, the wire routing portion 2100 extends between the front portion 2204 and the back portion 2206 of the HMD 2200 to span over the top of the head of the user 2202 or over the crown of the head of the user 2202. For example, the first end 2106 of the slider 2104 can be coupled to a display 2208 located at the front portion 2204 of the HMD 2200. In some cases, the first end 2106 can be hingedly, rotatably, or pivotally coupled to the display 2208 to allow the display 2208 to adjust and conform to the user 2202.

[0168] The slide 2104 can extend into or within the housing 2102 and engage the actuator 2114 via a slot 2116 on the slide 2104. The second end 2112 of the housing 2102 can engage with a rear portion 2206 of the HMD 2200, such as a housing or compartment 2210.

[0169] The user 2202 can use the actuator 2114 to extend the length of the slider 2104 protruding from the housing 2102, thereby adjusting the distance between the front 2204 and the rear 2206 of the HMD 2200. That is, actuating the actuator 2114 can cause the slider 2104 to extend from the housing 2102 or retract within the housing. When the slider 2104 is coupled to the display 2208 and the housing 2102 is coupled to the compartment 2210, actuating the actuator 2114 causes the slider 2104 to move to tighten and / or loosen from the user 2202.

[0170] like Fig. 22 As shown, the housing 2102 and / or the slider 2104 may include an arc that corresponds to or substantially corresponds to the shape of the top of the head of the user 2202. In addition, padding 2212 may be provided between the housing 2102 and the user 2202 to increase the comfort of the HMD 2200. Fig. 22 It is also shown that HMD 2200 may include a strap 2214, which may be similar to, correspond to, or include similar features as strap 1606.

[0171] Fig.23 An exemplary HMD 2300 is shown. Fig.23 As shown, HMD 2300 may include a top member 2302 extending from a front 2304 of HMD 2300 toward a rear 2306 of HMD 2300. A first end 2308 of top member 2302 is shown coupled to a display 2310 of HMD 2300 via hinge 2312. Thus, top member 2302 may be configured to pivot relative to display 2310 (e.g., about an X-axis) to confirm that display 2310 is aligned with the user's face when worn.

[0172] like Fig.23 As shown, and as discussed above with respect to HMD 100, HMD 1400, HMD 1600, and / or HMD 2200, top member 2302 can include a second end disposed within jacket 2314. Top member 2302 can include a slot engaged with top actuator 2316, which is coupled to jacket 2314. In some cases, the slot of top member 2302 can be similar to slot 118, and top actuator 2316 can be similar to top actuator 120, as discussed above with respect to HMD 100. Actuating top actuator 2316 can cause top member 2302 to telescopically extend and retract from jacket 2314 at various lengths, thereby increasing or decreasing the tightness of HMD 2300 on a user. In other words, actuating top actuator 2316 can increase or decrease the exposed length of top member 2302 from jacket 2314. The slot of the top member 2302 may be disposed within or within the jacket 2314.

[0173] In some cases, top member 2302 may include a flexible material (e.g., rubber, plastic, etc.) that is configured to be curved, bent, and / or otherwise conform to the user's head. In some cases, top member 2302 may also include a notch that allows top member 2302 to bend or flex.

[0174] In some cases, the top member 2302 can include a wire that is routed between the front portion 2304 and the back portion 2306 of the HMD 2300. In some cases, the wire can be integrally formed within the top member 2302 and can extend between a first end 2308 of the top member 2302 and a second end of the top member 2302. Between the first end 2308 and the second end, the wire can traverse around a slot within the top member 2302. Additionally, the wire can include slack external to (e.g., not embedded in) the top member 2302 that allows the top member 2302 to extend and retract from the jacket 2314 at varying lengths.

[0175] Fig.23 The top member 2302 is shown extending into the jacket 2314 at a first end 2318 of the jacket 2314. A second end 2320 opposite the first end 2318 of the jacket 2314 can be coupled to the rear 2306 of the HMD 2300 via a hinge 2322. The hinge 2322 can pivotally couple the second end 2320 of the jacket 2314 to the rear 2306 of the HMD 2300.

[0176] HMD 2300 includes rear actuator 2324 that can engage one or more cross members, such as first cross member 2326 and second cross member 2328. In some cases, first cross member 2326 and second cross member 2328 can be similar to first cross member 122 and second cross member 124, as discussed above with respect to HMD 100, and rear actuator 2324 can be similar to rear actuator 202 to operably engage first cross member 2326 and / or second cross member 2328.

[0177] Fig.24 2300. As shown, the top member 2302 can extend from the front 2304 of the HMD 2300 toward the rear 2306 of the HMD 2300 and can be operably engaged with the top actuator 2316 via a slot 2400 extending along a portion of the length of the top member 2302. Fig.24 23, slot 2400 is generally indicated by a dashed line. In some cases, slot 2400 can be similar to slot 118, as discussed above with respect to HMD 100. Thus, actuating top actuator 2316 can cause top member 2302 to extend from and retract within jacket 2314 at different lengths, thereby tightening and loosening HMD 2300 to the user. Fig.24 Also shown is the second end 2402 of the top member 2302 disposed within the jacket 2314.

[0178] Fig.25 A side view of HMD 2300 is shown showing top member 2302 pivotally coupled to front portion 2304 of HMD 2300 at first end 2308 and via hinge 2312. Second end 2320 of jacket 2314 may be pivotally coupled to rear portion 2306 of HMD 2300 via hinge 2322. Thus, HMD 2300 may be configured to conform to a user's head when worn.

[0179] The second end 2320 of the top member 2302 can extend transversely through the opening at the first end 2318 of the jacket 2314, and the slot 2400 can engage the top actuator 2316. Additionally, as described above, the top member 2302 can include wires disposed therein (e.g., embedded within the top member 2302) or coupled thereto to communicatively couple one or more computing components (e.g., antennas, displays, etc.) located at the front portion 2304 with one or more computing components (e.g., antennas, batteries, etc.) located at the rear portion 2306.

[0180] Fig.26A jacket 2314 of HMD 2300 is shown. In some cases, jacket 2314 can include a single piece of material, or can include multiple parts (e.g., two halves) that are assembled or coupled together. As shown, jacket 2314 can have an arcuate shape between first end 2318 and second end 2320.

[0181] The first end 2318 can include an opening 2600 that is sized and configured to receive the top member 2302. In some cases, the opening 2600 can include an opening of a channel 2602 disposed within the jacket 2314. The channel 2602 can include a passageway from which the top member 2302 can telescopically extend and retract within, thereby allowing the HMD 2300 to be tightened and loosened from the user. Within the channel 2602, the slot 2400 can engage the top actuator 2316. The channel 2602 can also be of sufficient size to allow one or more wires to extend therethrough.

[0182] The second end 2320 of the clip 2314 may include a hinge 2322 for pivotably coupling the clip 2314 with a rear portion 2306 of the HMD 2300 , such as a housing.

[0183] In addition, if Fig.26 As shown, the jacket 2314 can include an opening 2604 positioned proximate to the second end 2320 of the jacket 2314. The opening 2604 can extend through the sidewall of the jacket 2314 to provide an entrance or passageway into the channel 2602. For example, as described above, the top member 2302 can include a wire embedded therein, and a first end of the wire can extend from the first end 2308 of the top member 2302, and a second end of the wire can extend from the second end of the top member 2302. When the second end 2402 of the top member 2302 is disposed within the jacket 2314, the second end of the wire passageway exits from the jacket 2314 and / or the channel 2602 via the opening 2604. However, the opening 2604 can be located elsewhere proximate to the second end 2320 of the jacket 2314.

[0184] Fig. 27 A perspective view of the top member 2302 is shown. As shown, the top member 2302 can include an arcuate member extending between a first end 2308 and a second end 2402. As described above, the second end 2402 can be sized and configured to be inserted through the opening 2600 so that the top member 2302 can telescopically extend from and retract within the jacket 2314.

[0185] Top member 2302 can include wire 2700. In some cases, wire 2700 can be embedded within top member 2302. Fig. 272302. In the drawings, the wire 2700 is generally represented by a dashed line to illustrate the wire 2700 within the top member 2302. Additionally or alternatively, the wire 2700 may be attached, adhered, mounted, or otherwise coupled to the top member 2302. As shown, the wire 2700 may include a first end 2702 and a second end 2704, wherein the first end extends from the first end 2308 of the top member 2302 and the second end extends from the second end 2402 of the top member 2302. Between the first end 2702 and the second end 2704, the wire 2700 may pass through, along, and / or traverse within the top member 2302. In addition, because the top member 2302 includes slots 2400, which are configured to pass through the thickness or portion of the top member 2302, the wire 2700 may traverse along or around the slots 2400.

[0186] As discussed above, the second end 2704 of the wire 2700 can be in communication with or disposed through the opening 2604 of the jacket 2314. In order to allow the top member 2302 to extend from the jacket 2314 at different lengths in order to tighten and loosen the HMD 2300 to the user, the wire 2700 can include sufficient length and / or slack. For example, the wire 2700 can have a slack portion 2706 between the second end 2402 of the top member 2302 and the second end 2704 of the wire 2700. The slack portion 2706 can allow the top member 2302 to extend from the jacket 2314 at different lengths. In some cases, the slack portion 2706 can be coiled within the jacket 2314 to prevent the wire 2700 from bending or curling when extending from and retracting within the jacket 2314.

[0187] The top member 2302 may include a material (e.g., rubber, composite material, plastic, etc.) that allows the top member 2302 to flex or bend. In addition, the top member 2302 may include indentations, depressions, notches, or notches 2708 that allow or help allow the top member 2302 to bend.

[0188] Fig.28 A perspective view of second cross member 2328 is shown. Second cross member 2328 may include a first end 2800 for hingedly or pivotally coupling to a front portion 2304 (e.g., a display) of HMD 2300 and a second end 2802 for engaging a rear actuator 2324 of HMD 2300. For example, as shown, second cross member 2328 may include slots 2804 extending along at least a portion of the length of second cross member 2328, and the slots are configured to engage rear actuator 2324 at various locations. In some cases, slots 2804 may be similar to slots 706.

[0189] As shown, the second cross member 2328 may have an arcuate shape designed to extend between the front 2304 and the rear 2306 of the HMD 2300. As such, the second cross member 2328 may include a flexible material and / or a semi-rigid material (e.g., plastic, components, rubber, etc.).

[0190] The first cross member 2326 may include similar features as the second cross member 2328. For example, the second cross member 2328 may represent the first cross member rotated about the Z-axis.

[0191] Fig.29 An exemplary HMD 2900 is shown. Fig.29 As shown, HMD 2900 may include a top member 2902 extending from a front 2904 of HMD 2900 toward a rear 2906 of HMD 2900. A first end 2908 of top member 2902 is shown coupled (via a hinge) to a display 2910 of HMD 2900. Thus, top member 2902 may be configured to pivot relative to display 2910 to confirm that display 2910 is aligned with the user's face when worn.

[0192] The top member 2902 may extend into or through the jacket 2912 and route to the rear portion 2906 of the HMD 2900. As discussed in detail herein, a second end of the top member 2902 or a portion of the top member 2902 may engage with a first actuator 2914 that adjusts the configuration of the HMD 2900 on the user when worn. For example, the top member 2902 may include a slot that engages with the first actuator 2914. In some cases, the slot of the top member 2902 may be similar to the slot 118, and the first actuator 2914 may be similar to the top actuator 120, as discussed above with respect to the HMD 100. Thus, actuating the first actuator 2914 may cause the top member 2902 to telescopically extend and retract at various lengths, thereby increasing or decreasing the tightness of the HMD 2900 on the user. In some cases, the slot of top member 2902 can be disposed inside the rear portion of HMD 2900. Top member 2902 can include a flexible material (eg, rubber, plastic, etc.) configured to curve, bend, and / or otherwise conform to the user's head.

[0193] HMD 2900 also includes one or more cross-members, such as first cross-member 2916 and second cross-member 2918. In some cases, first cross-member 2916 and second cross-member 2918 can be similar to first cross-member 122 and second cross-member 124, as discussed above with respect to HMD 100. First cross-member 2916 and second cross-member 2918 can extend along opposite sides of HMD 2900 between front portion 2904 and rear portion 2906 and engage second actuator 2920. In such cases, first cross-member 2916 and / or second cross-member 2918 can extend into or be received by a portion of the housing that is located at the rear of HMD 2900.

[0194] In some cases, second actuator 2920 can be similar to rear actuator 202 and operably engage first cross member 2916 and second cross member 2918. Actuating second actuator 2920 can cause the exposed length of first cross member 2916 and second cross member 2918 to increase or decrease by t to tighten or loosen HMD 2900 to / from the user.

[0195] As shown, the first actuator 2914 and the second actuator 2920 can be disposed or positioned near the rear 2906 of the HMD 2900. That is, the first actuator 2914 of the HMD 2900 can be disposed near, proximate to, and / or at the rear 2906 of the HMD 2900, as compared to the HMD 100 (e.g., which has the top actuator 202 located at the top of the HMD 100). In some cases, positioning the first actuator 2914 and / or the second actuator 2920 at the rear 2906 of the HMD 2900 can allow a user to more conveniently tighten and loosen the HMD 2900 (i.e., because the first actuator 2914 and the second actuator 2920 can be disposed proximate to each other). Details of the first actuator 2914 and the second actuator 2920 are discussed herein.

[0196] HMD 2900 may also include a rear strap 2922 that engages the back of the user's head when HMD 2900 is worn. In some cases, rear strap 2922 may include slots or features that allow rear strap 2922 to flex or conform to the user's head (e.g., above and below the user's occipital lobe). In some cases, rear strap 2922 may engage or couple to the housing at rear 2906 of HMD 2900 using one or more ball joints.

[0197] As further discussed herein, the HMD 2900 may include a flexible printed circuit board assembly (FPCBA), one or more wires coupled together, and / or a flexible printed circuit (FPC) that communicatively couples components at the front 2904 with components at the rear 2906. In some cases, the FPC may be routed through a sheath and / or jacket 2912 to conceal the FPC and provide a clean aesthetic appearance for the HMD 2900. In some cases, the FPC may be coupled to a portion of the top member 2902 for routing the FPC between the front 2904 and the rear 2906. In addition, the FPC may include a service loop that provides slack for the FPC, thereby allowing the FPC to extend and retract when the HMD 2900 is tightened and loosened to the user (e.g., via actuation of the first actuator 2914 and the second actuator 2920). In some cases, the FPC may include an "S-shaped" service loop that is routed within the jacket 2912 to provide slack for the FPC when extending and retracting.

[0198] Although the HMD 2900 (or other HMDs discussed herein) is shown and described as including a first actuator 2914 and a second actuator 2920 that engage with the top member 2902 and engage with the first cross member 2916 and the second cross member 2918, respectively, in some cases, the HMD 2900 may include a single actuator that tightens and loosens the HMD 2900 to the user. For example, in some cases, the top member 2902, the first cross member 2916, and the second cross member 2918 may be engaged with a single actuator located at the rear 2906 of the HMD 2900. In this sense, the functions of the first actuator 2914 and the second actuator 2920 may be combined into a single actuator. For example, actuating (e.g., rotating) the actuator in a first direction may cause the HMD 2900 to be tightened, while actuating (e.g., rotating) the actuator in a second direction may cause the HMD 2900 to be loosened. To allow such operation, in some cases, the top member 2902, the first cross member 2916, and the second cross member 2918 may include a slot that engages with a single actuator. In some cases, the top member 2902 may engage with a first portion (e.g., a first gear) of the single actuator, and the first cross member 2916 and the second cross member 2918 may engage with a second portion (e.g., a second gear) of the single actuator. The first portion and the second portion may be operably coupled to the single actuator so that actuating the single actuator tightens and loosens the HMD 2900 to the user's head in multiple directions (e.g., vertically and horizontally). In some cases, the first portion and the second portion (or other portions of the single actuator) may have corresponding gear ratios (e.g., gear ratios) for tightening the top member 2902, the first cross member 2916, and the second cross member 2918. For example, the top member 2902, the first cross member 2916 and / or the second cross member 2918 can extend and / or retract at different rates.

[0199] Additionally or alternatively, HMD 2900 (or other HMDs discussed herein) may include self-tightening features that tighten HMD 2900 to the user. For example, one or more of top member 2902, first cross member 2916, and / or second cross member 2918 may be operably coupled to one or more motors within HMD 2900. Actuating the one or more motors may tighten top member 2902, first cross member 2916, and / or second cross member 2918. In some cases, HMD 2900 may include sensors disposed throughout HMD 2900 (e.g., on display 2910, on rear strap 2922, etc.) that sense forces applied by HMD 2900 on the user. If the force is too weak (which may indicate that the HMD 2900 is not securely fastened to the user), the one or more motors may tighten one or more of the top member 2902, the first cross member 2916, and / or the second cross member 2918 until the HMD 2900 is securely coupled to the user. Alternatively, if the sensor determines that the HMD 2900 is too tight, the one or more motors may loosen one or more of the top member 2902, the first cross member 2916, and / or the second cross member 2918. In some cases, the self-tightening feature may be used in conjunction with the user manually (or physically) operating the first actuator 2914 and / or the second actuator 2920.

[0200] In some cases, the HMD 2900 (or another communicatively coupled device) may store the user's head size or tightness preferences, features associated with the user profile, to automatically tighten the HMD 2900 to the user when worn. Such features may also learn the user's behavior to determine preferences associated with the user wearing the HMD 2900.

[0201] Additionally, in some cases, the HMD 2900 may be communicatively coupled to a mobile device to electronically tighten and loosen the HMD 2900. For example, the HMD 2900 may include a motor that may be operated by an application on the mobile device to tighten and loosen the HMD 2900. In some cases, such a motor may also be operated by one or more buttons located on the HMD 2900.

[0202] The HMD 2900 may further include one or more speakers disposed on the first cross member 2916 and / or the second cross member 2918 for outputting sound to the user.

[0203] Fig.30A first actuator 2914 and a second actuator 2920 are shown disposed at or near the rear 2906 of the HMD 2900. In some cases, the first actuator 2914 and / or the second actuator 2920 may be coupled to or disposed on the housing 3000 of the HMD 2900. In some cases, the first actuator 2914 may be disposed above the second actuator 2920 (in the Y direction). Within the housing 3000, the first actuator 2914 may engage with the top member 2902, and the second actuator 2920 may engage with the first cross member 2916 and / or the second cross member 2918. For example, the first actuator 2914 and / or the second actuator 2920 may include teeth, gears (e.g., spur gears), pinions, tabs, or sprockets inside the housing 3000 that engage with the oblique grooves of the top member 2902, the first cross member 2916, and the second cross member 2918, respectively. In this way, first actuator 2914 can cooperate with top member 2902 at different locations along its length to extend top member 2902 at different lengths from housing 3000. In some cases, first actuator 2914 and top member 2902 can adjust HMD 2900 on a user vertically or relative to the user's eyes.

[0204] In addition, the second actuator 2920 can cooperate with the first cross member 2916 and the second cross member 2918 at different positions along the length of the first cross member 2916 and the second cross member 2918, respectively, to extend the first cross member 2916 and the second cross member 2918 at different lengths from the housing 3000 (e.g., relative to Figure 7 In some cases, housing 3000 can include wings, arms, or extensions for receiving first cross member 2916 and second cross member 2918, respectively.

[0205] In some cases, the housing 3000 may include components of the HMD 2900, such as various input / output devices, a battery, a memory, a processor, a network interface, and the like. In order to communicatively couple these components with the display 2910 or other components (e.g., an antenna) disposed at the front 2904 of the HMD 2900, the HMD 2900 may include an FPC 3002. As discussed above, the FPC 3002 may be routed between the front 2904 and the back 2906 of the HMD 2900. In some cases, at least a portion of the FPC 3002 may be coupled (e.g., an adhesive) to at least a portion of the top member 2902. For example, the FPC 3002 may be coupled to an inner surface of the top member 2902, near the first end 2908 of the top member 2902 or near the front 2904 of the HMD 2900. Additionally or alternatively, in some cases, the FPC 3002 may be disposed within a sheath, cover, or other protective housing that wraps around the top member 2902 (or a portion thereof) to secure the FPC 3002 to the top member 2902.

[0206] Fig.31 A front view of the HMD 2900 is shown showing the top member 2902 extending from the front portion 2904 and into the jacket 2912 , with the pad 3004 disposed and / or coupled beneath the jacket 2912 .

[0207] Fig.32 A rear view of HMD 2900 is shown. In some cases, first actuator 2914 and / or second actuator 2920 can be disposed along a longitudinal axis 3200 (or plane) extending through the center of HMD 2900. In doing so, in some cases, first actuator 2914 and / or second actuator 2920 can be centered on HMD 2900 (X direction).

[0208] Fig.33 A top view of HMD 2900 is shown showing top member 2902 extending from front 2904 to rear 2906 and passing through jacket 2912 to engage first actuator 2914. Rear strap 2922 is shown extending from rear 2906 (such as housing 3000) to engage the user's head when worn.

[0209] Fig.34 A bottom view of HMD 2900 is shown showing top member 2902 extending from front 2904 to rear 2906 and passing through jacket 2912 to engage first actuator 2914. Rear strap 2922 is shown extending from rear 2906 (such as housing 3000) to engage the user's head when worn.

[0210] Fig.35 and Fig.36 A first side view and a second side view of the HMD 2900 are shown. As discussed above, the top member 2902 can extend through the jacket 2912. For example, in some cases, the top member 2902 can extend into the first end 3500 of the jacket 2912 and exit at the second end 3502 of the jacket 2912. Similarly, as discussed above, the FPC 3002 can be coupled along a portion of the top member 2902, such as near the front 2904 of the HMD 2900 and / or the rear 2906 of the HMD 2900. Additionally or alternatively, a jacket can be disposed over the FPC 3002 and / or the top member 2902 to abut or couple the top member 2902 and the FPC 3002. The jacket can also, for example, hide the FPC 3002. At locations between the FPCs 3002, the FPC 3002 can be snaking within the jacket 2912 to provide service loops or slack. In some cases, the FPC 3002 can be coupled to the top member 2902 at a location external to the jacket 2912 and can meander back and forth within the jacket 2912 (eg, Z direction) to provide slack for the FPC 3002 to extend and retract.

[0211] Likewise Fig.35 and Fig.36 As shown, the rear strap 2922 may extend from the housing 3000 so as to hold the back of the head when wearing the HMD 2900. The rear strap 2922 may include components for conforming to various head geometries. For example, a spring or other biasing member may connect the rear strap 2922 and the housing 3000 to provide pressure on the back of the head. The pressure may conform the rear strap 2922 to the user to provide a firm and comfortable configuration. Additionally or alternatively, the rear strap 2922 may include cutouts (e.g., slits, ovals, etc.) or gap points that provide the rear strap 2922 with flexure around one or more axes. For example, depending on the position and / or shape of these cutouts, the rear strap 2922 may be flexed at certain positions around one or more axes. The flexure may allow the rear strap 2922 to conform to the back of the entire user's head to reduce pressure points and / or evenly distribute pressure to the back of the head. In such cases, the rear strap 2922 may flex toward the front of the HMD 2900, toward the rear 2906 of the HMD 2900, toward one or more sides of the HMD 2900, and / or toward the top of the HMD 2900.

[0212] The differences in material and / or thickness of portions of the rear strap 2922 may also affect the flexing of the rear strap 2922. For example, different portions of the rear strap 2922 may be thicker, while other portions may be thinner. Such differences in thickness may affect the portion or location of the rear strap 2922 that is configured to flex to conform to the user's head. The multi-axis flexing of the rear strap 2922 may provide passive suspension of the back of the head.

[0213] Additionally, in some cases, rear strap 2922 can include pad 3004 that rests on the top of the user's head. In this sense, in some cases, pad 3004 can be integrally formed with rear strap 2922. However, in some cases, pad 3004 can include a separate component. In some cases, rear strap 2922 and / or pad 3004 can be coupled to jacket 2912, which can be used to position jacket 2912 on HMD 2900 or to set jacket 2912 on HMD 2900 (e.g., to prevent jacket 2912 from being repositioned and / or moved).

[0214] In some cases, the first actuator 2914 and / or the second actuator 2920 may be located on a portion of the housing 3000 that extends toward the front 2904 of the HMD 2900. In some cases, the first actuator 2914 may be disposed closer to the front 2904 (Z direction) of the HMD 2900 than the second actuator 2920. In some cases, this may help couple the top member 2902 to the first actuator 2914 and / or provide a comfortable wearability and feel when wearing the HMD 2900. That is, by disposing the first actuator 2914 and / or the second actuator 2920, the arc of the top member 2902 may continue into the housing 3000, as shown. In addition, positioning the first actuator 2914 and / or the second actuator 2920 on the inwardly inclined portion may help the user operate the first actuator 2914 and / or the second actuator 2920. In some cases, second actuator 2920 can be substantially horizontally aligned with first cross member 2916 and second cross member 2918. As discussed above, first actuator 2914 and / or second actuator 2920 can be angled or disposed and / or include corresponding shapes and / or features to engage top member 2902 and first cross member 2916 and second cross member 2918, respectively.

[0215] Fig.37The top member 2902, the jacket 2912, and the FPC 3002 are shown. The jacket 2912 is shown as transparent to show the routing of the FPC 3002 within the jacket 2912. In some cases, the FPC 3002 may be coupled to the underside of the top member 2902. In addition, as discussed above, in some cases, the top member 2902 and / or the FPC 3002 may be provided with a jacket 3700. The jacket 3700 may wrap around, surround, and / or enclose the top member 2902 and / or the FPC 3002 so as to couple the top member 2902 and / or the FPC 3002 together. The jacket 3700 may extend along a portion of the length of the top member 2902 and / or the FPC 3002. In some cases, the jacket 3700 may extend into the first end 3500 of the jacket 2912.

[0216] The sheath 3700 may include an end 3702 at which the FPC 3002 exits the sheath 3700 and loops back in a direction toward the front 2904 of the HMD 2900. The FPC 3002 may include a service loop 3704 disposed within the jacket 2912 and providing slack to allow the FPC 3002 to extend and retract as the top member 2902 extends and retracts. In some cases, the service loop 3704 may remain within the jacket 2912 as the top member 2902 extends and / or retracts. For example, in some cases, the sheath 3700 may be coupled to the jacket 2912. After winding through the jacket 2912, the FPC 3002 may exit the jacket 2912 at the second end 3502, at which point the FPC 3002 may be coupled to the top member 2902 and extend into the housing 3000.

[0217] To further illustrate, a first end of the FPC 3002 may be coupled adjacent to the first end 2908 of the top member 2902. The FPC 3002 may then be coupled to the top member 2902 and / or extend through the jacket 3700. In some cases, the FPC 3002 may exit the jacket 3700 at the end 3702 of the jacket 3700, at which point the FPC 3002 may extend in a direction toward the front 2904 of the HMD 2900 (i.e., thereby providing a service loop 3704) before looping back and extending in a direction toward the rear 2906 of the HMD 2900. The FPC 3002 may then exit the jacket 2912, and a second end of the FPC 3002 may be communicatively coupled to a component within the housing 3000. In some cases, rather than the jacket 3700 including an end, the jacket 3700 may include a slit or slot through which the FPC 3002 exits (and / or re-enters) to create the service loop 3704.

[0218] In some cases, portions of top member 2902 and / or FPC 3002 away from second end 3502 may also be disposed in a jacket or other protective housing to further provide an aesthetic appearance to HMD 2900. Additionally, while the above discussion is with respect to jacket 2912 as a separate component or feature of housing 3000, in some cases, jacket 2912 may be integrally formed with housing 3000.

[0219] Fig.38 Shown along Fig.34 2900. As shown, the FPC 3002 may be circulated within the jacket 2912 to provide a service loop 3704. The jacket 2912 may include an area or chamber for the FPC 3002 to loop back toward the second end 3502 of the jacket.

[0220] Fig.39 An HMD 3900 is shown with a single knob 3902 disposed at the rear of the HMD 3900. The single knob 3902 may engage with one or more members that are used to tighten and loosen the HMD 3900 to the user. In some cases, the one or more members may engage with the single knob 3902 within the rear housing of the HMD 3900. For example, the top member may extend through the top jacket 3904 and engage with the single knob 3902. The cross members may extend through the cross jackets 3906 and 3908 to engage with the single knob 3902. In such cases, the user may operate the single knob 3902 to control the tightening and loosening of the top member and the cross member (e.g., via the single knob 3902 that engages with the slots of the top member and the slots of the cross member, respectively). In some cases, the cross members may overlap within the rear housing to allow the cross members to tighten and loosen (or extend and retract). The top member may be rolled, coiled, or extended within the rest of the shell to allow the top member to be tightened and loosened (or extended and retracted).

[0221] In some cases, a single knob 3902 may be considered a dual concentric knob that includes multiple knobs or actuators for tightening and loosening the top member and the cross member, respectively. For example, a single knob 3902 may include multiple knobs that are nested or integrated with each other. For example, Fig.39 A single knob 3902 is shown that can include a first knob 3910 and a second knob 3912. In some cases, the first knob 3910 can be disposed in front of the second knob 3912. As shown, and in some cases, the second knob 3912 can have a larger diameter than the first knob 3910. In some cases, the first knob 3910 and the second knob 3912 can be concentric.

[0222] The first knob 3910 and the second knob 3912 may be independently actuated in multiple directions for tightening and loosening the HMD 3900. For example, the first knob 3910 may be engaged with the top member and rotated in a first direction (e.g., clockwise) to tighten the HMD 3900, and rotated in a second direction (e.g., counterclockwise) to loosen the HMD 3900. The second knob 3912 may be engaged with the cross member and rotated in a first direction (e.g., clockwise) to tighten the HMD 3900, and rotated in a second direction (e.g., counterclockwise) to loosen the HMD 3900. In some cases, the first knob 3910 and the second knob 3912 may be engaged with the top member and the cross member, respectively, inside the rear housing, the top jacket 3904, and / or the cross jackets 3906 and 3908.

[0223] Fig.40 Shows Fig.39 3900. As described above, the lateral jackets 3906 and 3908 can route the lateral members toward the rear of the HMD 3900 for engagement with the single knob 3902. In some cases, the lateral members can engage with one of the first knob 3910 or the second knob 3912. Similarly, the top jacket 3904 can route the top member toward the rear of the HMD 3900 for engagement with the single knob 3902 or one of the first knob 3910 or the second knob 3912. As shown, the first knob 3910 can be disposed in front of the second knob 3912 (e.g., the second knob 3912 is disposed proximate to the HMD 3900 or the rear housing), and the first knob 3910 and the second knob 3912 can be concentric.

HMD 4100 may represent, correspond to, or be similar to HMD 100, HMD 1400, HMD 1600, HMD 2200, HMD 2300, and / or HMD 2900 referenced herein, and thus, Fig.29 The components of HMD 4100 shown in FIG. 4 may be implemented in HMD 100 , HMD 1400 , HMD 1600 , HMD 2200 , HMD 2300 , HMD 2900 , and / or HMD 3900 .

[0225] In some cases, the HMD 4100 may be implemented as a standalone device worn by a user (e.g., on the user's head), and may be head-mounted, such as by allowing the user to secure the HMD 4100 on his / her head, and may be adjustable to accommodate different users. In some embodiments, the HMD 4100 includes a VR or AR headset that includes a near-eye or near-eye display.

[0226] HMD 4100 may include one or more processors 4102 and memory 4104 (e.g., computer-readable media). In some implementations, processor 4102 may include a central processing unit (CPU), a graphics processing unit (GPU), both a CPU and a GPU, a microprocessor, a digital signal processor, or other processing units or components known in the art. Alternatively or in addition, the functions described herein may be performed at least in part by one or more hardware logic components. For example, but not limited to: exemplary types of hardware logic components that can be used include field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), application specific standard products (ASSPs), systems on chips (SOCs), complex programmable logic devices (CPLDs), etc. In addition, each processor in processor 4102 may have its own local memory, which may also store program modules, program data, and / or one or more operating systems.

[0227] The memory 4104 may include volatile and non-volatile memory, removable and non-removable media implemented in any method or technology for storing information such as computer-readable instructions, data structures, program modules, or other data. Such memory includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical storage, cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, RAID storage systems, or any other medium that can be used to store the required information and can be accessed by the computing device. The memory 4104 may be implemented as a computer-readable storage medium ("CRSM"), which can be any available physical medium that the processor 4102 can access to execute the instructions stored on the memory 4104. In a basic implementation, the CRSM may include random access memory ("RAM") and flash memory. In other implementations, the CRSM may include, but is not limited to, read-only memory ("ROM"), electrically erasable programmable read-only memory ("EEPROM"), or any other tangible medium that can be used to store the required information and can be accessed by the processor 4102.

[0228] In general, the HMD 4100 may include logic (e.g., software, hardware, and / or firmware, etc.) configured to implement the techniques, functions, and / or operations described herein. The memory 4104 is shown to include various modules, such as instructions, data storage, etc., which can be configured to execute on the processor 4102 to implement the techniques, functions, and / or operations described herein. Some exemplary functional modules are shown to be stored in the memory 4104 and executable on the processor 4102, but the same functions may alternatively be implemented in hardware, firmware, or a system on a chip (SOC) and / or other logic.

[0229] The operating system module 4106 may be configured to manage hardware located within and coupled to the HMD 4100 for the benefit of other modules. In addition, in some instances, the HMD 4100 may include one or more applications 4108 stored in the memory 4104 or otherwise accessible by the HMD 4100. In some cases, the application 4108 includes a game application 4110. However, the HMD 4100 may include any number or type of applications. The game application 4110 may be configured to initiate a game start of a video-based interactive game (e.g., a VR game) that can be played by a user and output frames to be rendered on the display panel of the HMD 4100.

[0230] HMD 4100 includes an input device 4112 and an output device 4114. Input device 4112 may include control buttons. In some implementations, one or more microphones may be used as input device 4112 to receive audio input, such as user voice. In some implementations, one or more cameras or other types of sensors (e.g., inertial measurement units (IMUs)) may be used as input device 4112 to receive gesture input, such as hand movements and / or head movements of the user. In some embodiments, additional input devices 4112 may be provided in the form of keyboards, keypads, mice, touch screens, joysticks, etc. In other embodiments, HMD 4100 may omit keyboards, keypads, or other similar forms of mechanical input. On the contrary, HMD 4100 may be implemented with a relatively simple form of input device 4112, (wireless or wired based) network interface, power and processing / storage capabilities. For example, a limited set of one or more input components (e.g., dedicated buttons for initiating configuration, power on / off, etc.) may be used so that HMD 4100 can be used later. In one implementation, the input device 4112 may include control mechanisms such as basic volume control buttons for increasing / decreasing the volume, as well as power and reset buttons.

[0231] Output device 4114 may include an electronic display 4116, which may be the same as or similar to display 108 described above. Output device 4114 may also include, but is not limited to, light emitting elements (e.g., LEDs), vibrators for generating tactile sensations, speakers (e.g., headphones), etc. Light emitting elements (e.g., LEDs) are used to indicate status, such as when powered on.

[0232] The HMD 4100 may include a wireless unit 4118 coupled to one or more antennas 4120 to facilitate wireless connection to a network. The wireless unit 4118 may implement one or more of a variety of wireless technologies, such as Wi-Fi, Bluetooth, radio frequency (RF), etc. However, the HMD 4100 may also include physical ports to facilitate wired connections to a network, connected peripherals (including PCs, game consoles, etc.), or plug-in network devices that communicate with other wireless networks.

[0233] HMD 4100 may include an optical subsystem 4122 that uses one or more optical elements to direct light from the electronic display 4116 to the user's eyes. The optical subsystem 4122 may include various types of different optical elements and combinations thereof, including, but not limited to, such as holes, lenses (e.g., Fresnel lenses, convex lenses, concave lenses, etc.), filters, etc. In some embodiments, one or more optical elements in the optical subsystem 4122 may have one or more coatings, such as anti-reflective coatings. The amplification of the image light by the optical subsystem 4122 allows the electronic display 4116 to be physically smaller, lighter, and consume less power than a larger display. In addition, the amplification of the image light can increase the field of view (FOV) of the displayed content (e.g., an image). For example, the FOV of the displayed content causes the displayed content to use almost all of the user's FOV (e.g., 120 degrees to 150 degrees diagonal) and in some cases all of the user's FOV for presentation. AR applications may have a narrower FOV (e.g., about 40 degrees FOV). The optical subsystem 4122 may be designed to correct one or more optical errors, such as, but not limited to, barrel distortion, pincushion distortion, longitudinal chromatic aberration, lateral chromatic aberration, spherical aberration, coma, field curvature, astigmatism, etc. In some embodiments, the content provided to the electronic display 4116 for display is pre-distorted, and the optical subsystem 4122 corrects the distortion when it receives image light generated based on the content from the electronic display 4116.

[0234] HMD 4100 may also include one or more sensors 4124, such as sensors for generating motion, position, and orientation data. Sensors 4124 may include gyroscopes, accelerometers, magnetometers, cameras, color sensors, or other motion, position, and orientation sensors. Sensors 4124 may also include sub-portions of sensors, such as a series of active or passive markers that can be observed from the outside by a camera or color sensor to generate motion, position, and orientation data. For example, a VR headset may include multiple markers on its outside, such as reflectors or lights (e.g., infrared or visible lights), which, when observed by an external camera or illuminated by light (e.g., infrared or visible light), may provide one or more reference points for software to interpret in order to generate motion, position, and orientation data. HMD 4100 may include a light sensor that is sensitive to light (e.g., infrared or visible light) projected or broadcast by a base station into the environment of HMD 4100.

[0235] In one example, the sensor 4124 may include an inertial measurement unit (IMU) 4126. The IMU 4126 may be an electronic device that generates calibration data based on measurement signals received from an accelerometer, a gyroscope, a magnetometer, and / or other sensors suitable for detecting motion, correcting errors associated with the IMU 4126, or some combination thereof. Based on the measurement signals, such motion-based sensors such as the IMU 4126 may generate calibration data that indicates an estimated position of the HMD 4100 relative to an initial position of the HMD 4100. For example, multiple accelerometers may measure translational motion (forward / backward, up / down, left / right), and multiple gyroscopes may measure rotational motion (e.g., pitch, yaw, and roll). The IMU 4126 may, for example, rapidly sample the measurement signals and calculate an estimated position of the HMD 4100 based on the sampled data. For example, the IMU 4126 may integrate the measurement signals received from the accelerometer over time to estimate a velocity vector, and integrate the velocity vector over time to determine an estimated position of a reference point on the HMD 4100. A reference point is a point that can be used to describe the position of the HMD 4100. Although a reference point may generally be defined as a point in space, in various embodiments, the reference point is defined as a point within the HMD 4100 (e.g., the center of the IMU 4126). Alternatively, the IMU 4126 provides the sampled measurement signals to an external console (or other computing device) that determines calibration data.

[0236] As mentioned, in some embodiments, the sensors 4124 may include light sensors that are sensitive to light emitted by base stations in the environment of the HMD 4100 for the purpose of tracking the position and / or orientation, posture, etc. of the HMD 4100 in 3D space. The calculation of the position and / or orientation may be based on the timing characteristics of the light pulses and the presence or absence of light detected by the sensors 4124.

[0237] The HMD 4100 may also include an eye tracking module 4128. A camera or other optical sensor inside the HMD 4100 may capture image information of the user's eyes, and the eye tracking module 4128 may use the captured information to determine interpupillary distance, interocular distance, a three-dimensional (3D) position of each eye relative to the HMD 4100 (e.g., for the purpose of distortion adjustment), including the magnitude of the twist and rotation (i.e., roll, pitch, and yaw) of each eye, and the gaze direction. In one example, infrared light is emitted within the HMD 4100 and reflected from each eye. The reflected light is received or detected by a camera of the HMD 4100 and analyzed to extract eye rotation from changes in the infrared light reflected by each eye. The eye tracking module 4128 may use many methods for tracking the eyes of the user 102. In some cases, the eye tracking module 4128 can track up to six degrees of freedom (i.e., 3D position, roll, pitch, and yaw) for each eye, and at least a subset of the quantities tracked from both eyes of the user can be combined to estimate the gaze point (i.e., the 3D location of where the user is looking or the position in the virtual scene). For example, the eye tracking module 4128 can integrate information from past measurements, measurements identifying the position of the user's head, and 3D information describing the scene presented by the electronic display 4116. Information for the position and orientation of the user's eyes can be used to determine the gaze point that the user is looking at in the virtual scene presented by the HMD 4100.

[0238] HMD 4100 may include a head tracking module 4130. The head tracking module 4130 may utilize one or more of the sensors 4124 to track the user's head movement (including head rotation), as described above. For example, the head tracking module 4130 may track up to six degrees of freedom (i.e., 3D position, roll, pitch, and yaw) of the HMD 4100. These calculations may be performed at each frame in a series of frames so that the application 4108 may determine how to render the scene in the next frame based on the head position and orientation. In some embodiments, the head tracking module 4130 is configured to predict the future position and / or orientation of the HMD 4100 based on current and / or past data. This is because the application is required to render the frame before the user actually sees the light on the electronic display 4116 (and therefore sees the image). During operation, the head tracking module 4130 of the HMD 4100 may generate data about the position and posture of the HMD 4100, which is provided to the application so as to notify the application about how to render the next frame in the series of frames based on the positioning / posture of the user's head position. This allows the image to be rendered within the image area on the electronic display 4116 in a manner that makes the user believe that he / she is viewing a virtual environment that includes objects (both static and moving) around, and these objects move with the user's head within the scene in an expected manner. Therefore, frames can be rendered based on this future prediction of the head position and / or orientation made at an earlier point in time (such as approximately 25 milliseconds (ms) to 30 milliseconds before the rendered frame). The rotation data provided by the head tracking module 4130 can be used to determine both the direction of rotation of the HMD 4100 and the amount of rotation of the HMD 4100 in any suitable measurement unit. For example, the direction of rotation can be simplified and output according to the positive or negative horizontal direction and the positive or negative vertical direction corresponding to left, right, up and down. The amount of rotation can be in terms of degrees, radians, etc. Angular velocity can be calculated to determine the rotation rate of the HMD 4100.
