Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Patent Application No. 18 / 342,527, filed on June 27, 2023, and entitled “HEAD-MOUNTABLE ELECTRONIC DEVICE SPACER,” and U.S. Provisional Patent Application No. 63 / 367,472, filed on June 30, 2022, and entitled “HEAD-MOUNTABLE ELECTRONIC DEVICE SPACER,” the entire disclosures of which are hereby incorporated by reference into this document. Technical Field

[0003] The embodiments generally relate to wearable electronic devices. More specifically, embodiments of the present invention relate to adjustment mechanisms, devices and systems for wearable electronic devices. Background Art

[0004] Recent advances in portable computing have enabled head-mounted devices to provide users with augmented reality (AR) and virtual reality (VR) experiences. Various components of these devices, such as displays, viewfinders, lenses, batteries, motors, optical seals, speakers, and other components work together to provide an immersive experience. Each user has unique anatomical features, including head size, eye position, cheek and forehead bone structure, etc., and head-mounted devices must adapt to these features to provide a customized, comfortable fit to bring a fully immersive experience. When wearing a head-mounted device, the user may need to make adjustments to provide the expected customized experience. These adjustments may include adjusting straps, viewfinders, lens width, depth spacing, speaker volume, component position, or other desired adjustments. Adjustments to viewfinder spacing and lenses may be particularly important because these adjustments affect the visual quality and content of the device experienced by the user.

[0005] Some devices may only provide a limited number of adjustments and may not be calibrated for the user, which may cause the image to become distorted when the user is viewing visual content, thereby detracting from the optimal viewing experience. Additionally, producing variations of a single device to accommodate individual users may create the need for additional stock keeping units (SKUs) in addition to increasing time, manufacturing complexity, and product cost.

[0006] Therefore, what is needed in the art are devices and systems that can provide user-specific spacing for head-mountable devices to meet the individual needs of the user. Summary of the invention

[0007] In one example of the present disclosure, a head-mounted device includes: a display portion having a shell and a display; an optical seal extending from the shell and including being offset a certain distance from the shell; and an adjustment mechanism coupled to the shell and the optical seal and configured to change the distance.

[0008] In one example, the optical seal includes a compliant sheath that defines an internal volume. In one example, the adjustment mechanism includes a base that is at least partially disposed within the internal volume. In one example, the head-mountable device also includes a frame coupled to the shell, wherein the base is connected to the frame, and the angle of the base relative to the frame is adjustable. In one example, the head-mountable device also includes a frame, wherein the shell defines an external surface of the display portion, the shell is coupled to the frame, and the adjustment mechanism is coupled to the frame. In one example, the adjustment mechanism is coupled to the frame and extends into the optical seal. In one example, the optical seal and the shell hide the adjustment mechanism from view.

[0009] In one example of the present disclosure, an electronic display device includes: a shell defining a front side and a rear side; and a light seal extending from the rear side, the light seal having an upper portion extending a first distance from the shell and a lower portion extending a second distance from the shell; and an adjustment mechanism configured to change the first distance or the second distance.

[0010] In one example, the upper portion is a first upper portion, and the lower portion is a first lower portion, and the light seal also includes a second upper portion extending a third distance from the housing and a second lower portion extending a fourth distance from the housing. In one example, the adjustment mechanism is configured to independently change the first distance, the second distance, the third distance, and the fourth distance. In one example, the display device also includes a frame to which the housing is coupled, wherein the adjustment mechanism includes a first base coupled to the frame and a second base coupled to the frame. In one example, the first base is coupled to the frame via a variable length mechanism. In one example, the first base is coupled to the frame via a pivot mechanism. In one example, the electronic display device also includes a frame to which the housing is attached, wherein at least one of the first base and the second base is coupled to the housing via the frame. In one example, the electronic display device may further include a display, wherein adjusting the first distance or the second distance changes the angle or distance of the display relative to the user's eyes.

[0011] In one example of the present disclosure, a head-mounted electronic device includes: a display portion having a display screen; an optical seal connected to the display portion, the optical seal including an adjustment mechanism; and a fixing strap configured to maintain the display screen in front of the eye at a certain distance and at a certain angle relative to the eye, wherein the adjustment mechanism is configured to change the distance and the angle.

[0012] In one example, the optical seal defines a contact surface to press against a face around the eyes and block ambient light from being incident on the display screen. In one example, the adjustment mechanism includes a first variable length mechanism coupled to the housing and a second variable length mechanism coupled to the housing. In one example, changing the length of the first variable length mechanism changes the distance or the angle. In one example, the optical seal defines an internal sealed volume, and the adjustment mechanism is disposed within the internal volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Reference will now be made to the examples shown in the accompanying drawings. It should be understood that the following description is not intended to limit the examples to a preferred embodiment. On the contrary, it is intended to cover alternatives, modifications and equivalents that may be included within the spirit and scope of the embodiments defined by the appended claims.

[0032] The following disclosure relates to wearable electronic devices. More specifically, embodiments of the present invention relate to adjustment mechanisms and spacers, devices, and systems for head-mounted electronic devices that are simpler than conventional adjustment mechanisms, require fewer parts, and can be easily, precisely, and accurately adjusted by users, retailers, or manufacturers without the need for multiple SKUs. When wearing a head-mounted electronic device (including the head-mounted AR / VR devices described herein), the position of certain components of the device relative to certain features of the user can affect the quality of the user experience. An example includes the distance of one or more displays relative to the user's eyes. Each user may have unique facial features, such as variations in cranial width or length, which may be caused by variations in the facial bones that press against the head-mounted electronic device. Variations in facial anatomy between users complicate the problem of providing components that are positioned within strict dimensional tolerances relative to the user's eyes, which is required for an optimal viewing experience.

[0033] In addition, the adjustment mechanisms and adjustment spacers for electronic devices described herein can be manufactured using a minimum number of SKUs while enabling user-specific adjustments to customize the placement distance and angle of displays, lenses, or other components of head-mounted electronic devices. The adjustment mechanism can enable users to easily self-adjust components or manufacturers and retailers to adjust components as needed to fit each user profile, thereby providing the user with an optimal viewing experience. In at least one example, the adjustment of the angle and distance of the display screen can be modified by an adjustment mechanism coupled to the housing and the optical seal. The optical seal can be designed to press against the user's face, such as around the user's eyes and above the nose, to minimize exposure to external light to the user while maintaining an optimal viewing distance and angle of the display screen that is applicable to the user.

[0034] As another example, a light seal that may be constructed of a compliant material may extend from a housing using an adjustment mechanism that includes a base. The base of the adjustment mechanism may be pressed against the user's face in a manner that light is minimized and the correct viewing distance and optimal viewing angle are maintained. In doing so, a more immersive and personal experience is provided to the user. Similarly, there may be two, four, six, eight or more adjustment mechanisms, each of which is customized for a user's specific facial anatomical variations. By having the adjustment mechanism at least partially embedded within the interior volume of the light seal, this may provide the user with an increased level of comfort while appropriately shielding the user from external light contamination that may be caused by ambient light.

[0035] In at least one example, the electronic display device may have a light seal extending from the peripheral edge of the rear side, the light seal having an upper portion and a lower portion that can be independently adjusted to conform to the contour of the user's face. These upper and lower portions may have multiple adjustable mechanisms that can be independently configured to change each of the first, second, third, or fourth distances relative to the user's face. These independently adjustable portions can be directly or indirectly configured to pivot, rotate, slide, translate, step, or otherwise move via a pivot attachment. In one example, the adjustment mechanism can be manually adjusted by a user, manufacturer, or retailer. Additionally or alternatively, in one or more examples, the adjustment mechanism can be electronically actuated.

[0036] The pivoting attachment may be machined, injection molded, formed, stamped, printed using additive manufacturing techniques, or produced using any other manufacturing method whereby the pivoting attachment may accomplish the intended task of conforming to the user's facial contours. In this manner, the user's viewing experience may be enhanced and customized to the user's anatomical features. Similarly, the pivoting attachment may be attached directly or indirectly to the base. The base may provide additional customization and comfort to the user, further enhancing the user's viewing experience.

[0037] As another example, the electronic display device can be conformed to the user's facial anatomical features by means of a gasket or a spacer or a combination thereof. The gasket or spacer can be connected to the electronic display device by a mechanical latch, a magnetic interface, a snap-fit ​​connection, or by other connection methods intended to fix the gasket or spacer to the electronic display device. These gaskets or spacers can be designed to adapt to a certain range of users of each SKU, which can reduce the total SKU required, thereby simplifying the manufacturing process and reducing costs, while the user can still be suitable for providing an optimized viewing experience. The gasket or spacer can be placed between the electronic display device and the light seal visible to the user, or the gasket or spacer can be contained inside the light seal and hidden from the user. An optimized viewing window can be formed for each user, and the optimized viewing window can vary with the angle and distance of the screen relative to the user's eyes, which can vary with the user and depend on the user's anatomical features. The functional envelope may define the limits at which the viewing window is optimized, which may be between about 2 mm and 100 mm, such as between about 5 mm and 50 mm, between about 10 mm and 40 mm, or more specifically between about 15.0 mm and 30 mm, relative to the user's eyes. The correct combination of depth and angle for each user may be accomplished through the use of shims, spacers, or other mechanical or electromechanical methods that produce a user-specific angle and distance combination that is contained within the functional envelope for optimized viewing.

[0038] In yet another example, the light seal may have an interior volume in which the adjustment mechanism may be placed, thereby covering the light seal and making it invisible. The adjustment mechanism may be continuous, consisting of one face contact portion attached to the electronic display device, or it may be discrete, consisting of multiple face contact portions that work together to appropriately conform to the user's facial contours. In doing so, the light seal is able to press against the face and block ambient light from being incident on the display screen, while also providing an appropriate screen distance and angle specific to the user relative to the user's eyes.

[0039] Because the devices described herein can provide a head-mounted device with additional advantages over previously available, such as continuously and adjustable user or manufacturer adjustable screen distance and angle features, it can better meet the individual needs of each user without requiring manufacturers to produce additional SKUs.

[0040] Reference below Figures 1 to 13To discuss these embodiments and other embodiments. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for illustrative purposes only and should not be construed as limiting. In addition, as used herein, a system, method, article, component, feature, or sub-feature comprising at least one of a first option, a second option, or a third option should be understood to refer to a system, method, article, component, feature, or sub-feature that may include one of each listed option (e.g., only one first option, only one second option, only one third option), multiple of a single listed option (e.g., two or more first options), two options at the same time (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0041] Figure 1 A top view of a head mountable device 100 is shown, including a display portion 102 having a housing 112 and a display screen fixed to, on, or within an interior volume defined by the housing 112. The display screen is not shown. Figure 1 1, but will be described in more detail with reference to other figures. The device may also include a light seal 106 extending from the housing 112 to contact the user 101. The securing band 104 may extend from the display portion 102 and / or the light seal 106 and surround the head of the user 101 to secure the device 100 against the face 111 of the user 101. Specifically, in at least one example, the securing band 104 may press inwardly around the head of the user 101 to press the light seal 106 against the face of the user 101.

[0042] exist Figure 1 , a user 101 wearing the device 100 is shown. In at least one example, the optical seal 106 may extend from the housing 112 and include a contact surface 109. The contact surface 109 may be formed in the shape of the user's face 111 and offset from the housing 112 by a certain distance 113. In at least one example, the optical seal 106 may be formed of an elastic or compliant material so that when the fixing strap 104 presses the device 100 against the face of the user 101, the optical seal compresses and conforms to the user's face 111. In one example, the optical seal 106 is formed with a contact surface 109 configured to complement the contour of the user's face 111. The optical seal 106 conforms to the user's face 111, and more specifically the contact surface 109 conforms to the user's face 111, forming a seal between the user's face 111 and the display portion 102 or its housing 112 to block light from the ambient environment outside the device 100 from being incident on one or more display screens of the display portion 102 during operation, thereby projecting light onto the user's face 111.

[0043] In at least one example, when the optical seal 106 conforms to the user's face 111, the distance 113 from the housing 112 to the contact surface 109 can vary at different points or locations along the optical seal 106. The device 100 may include a display portion 102 having a housing 112 that is manufactured and formed as a single SKU according to a common dimension, size, and shape regardless of anatomical variations of different users 101, while the optical seal 106 conforms as described above to accommodate various unique features and shapes / contours of different users 101. The optical seal 106 may also include a single SKU that is conformable or changeable in some manner to accommodate different anatomical features of different users 101. Typically, the optical seal 106 is configured to contact the user's face 111, including the forehead, cheeks, nose, and other anatomical features around the eyes of the user 101.

[0044] The consistent contact of the contact surface 109 against the user's face 111 can block light from the external environment to isolate the light projected by the display portion 102 toward the user's eyes for the best quality visual experience. The display portion 102 of the device 100 may include one or more displays, including Figure 1 One or more display screens, not shown, are arranged together with, on, or within the display portion 102 or its housing 112. Figure 1 As shown, when the device 100 is worn, the display can be configured to direct light and images toward the eyes of the user 101. The optical seal 106 described herein may include one or more adjustment mechanisms (including adjustment spacers) to change the distance 113 between the contact surface 109 and the housing 112 at different points or locations along the optical seal 106 while maintaining consistent contact between the contact surface 109 and the user's face 111 for optical sealing purposes. Note that Figure 1 The distance 113 shown and labeled indicates the distance between the display portion 102 or its housing 112 and the user's face 111 at one point of contact between the contact surface 109 of the optical seal 106 and the user's face 111. Due to the conformable nature of the optical seal 106 discussed above, the distance 113 can vary from one point of contact to another. That is, the distance 113 separating the display portion 102 from the user's face 111 by the optical seal 106 can vary around the user's face 111.

[0045] also, Figure 1 The distance 113 shown is with reference to the position of the housing 112 relative to the user's face 111. However, as will be described in more detail below with reference to other figures, the distance 113 may also be indicative of one or more displays ( Figure 1111 and more specifically, the position of the display screen connected to the housing 112 relative to the user's 101 eyes. That is, the display portion 102 may include a display, such as a display screen fixed in an appropriate position relative to the housing 112 of the display portion 102. Therefore, when referring to the distance 113 of the housing 112 relative to the user's face 111, the distance 113 provided by the optical seal 106 can also determine the distance of the display screen connected to the housing 112 relative to the user's 101 eyes. Such a display of the display portion 2 is shown in subsequent figures and includes at least Figures 2 to 3 and FIG. 5A to FIG. 11 , and are described below.

[0046] Figure 1 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 1 Examples of equipment, features, components and parts shown.

[0047] Figure 2 A side view of a user 201 wearing a head mountable device including a display portion 202 is shown. Figure 2 A cross-sectional view of the display portion 202 is shown. In at least one example, the display portion 202 may include a housing 212 and an optical seal 206 extending from the housing 212 to contact the user 201. Specifically, a first portion of the optical seal 206 may extend from the housing 212 to the forehead 203 of the user 201, and another portion of the optical seal 206 may extend from the housing 212 to the cheek 205 of the user 201. In addition, in at least one example, the display portion 202 may include a frame 210. The display 208 may be fixed, connected, or coupled to the display portion 202 via the frame 210. In one or more other examples, the display 208 may be coupled to the housing 212 of the display portion 202.

[0048] In at least one example, display 208 may include a display screen configured to direct light toward user eyes 207 when user 201 wears display portion 202. Figure 2 As shown, the display portion 202 can be fixed against the user's face, including the forehead 203, cheeks 205, and other facial anatomical features around the user's eyes 207, so that the display 208 is configured to direct light toward the user's eyes 207 during use. As described above, the light seal 206 can define a distance 213 separating the housing 212 from the user 201. Figure 2As shown in the cross-sectional view of the display portion 202 of FIG. 2 , the optical seal 206 may define a plurality of distances 213a, 213b separating the housing 212 from the face of the user 201. As described above, the face of the user 201 may include the user's forehead 203, cheeks 205, and any other portion around the user's 201 eyes 207, including the nose, temples, and the like. For example, an upper portion of the optical seal 206 may define a first distance 213a between the housing 212 and the forehead 203, while a second lower portion of the optical seal 206 may define a second distance 213b between the housing 212 and the cheek 205.

[0049] also, Figure 2 The display 208 is shown coupled to the housing 212 via the frame 210 such that the distances 213a and 213b determine another distance 215 between the user's eye 207 and the display 208. In addition, in at least one example, the optical seal 206 can also determine an angle β of the gaze direction of the eye 207 relative to a direction 217 perpendicular to the surface of the display 208 facing the eye 207 due to the different distances 213a and 213b separating the housing 212 from the forehead 203 and the cheek 205, respectively.

[0050] In at least one example of the present disclosure, the optical seal 206 can include adjustment spacers and mechanisms to change the distances 213a, 213b in order to change the distance 215 between the display 208 and the eye 207 and change the angle β of the display 208 relative to the eye 207. Figure 2 The adjustment spacers and mechanisms, not shown, may be automatically and / or manually adjusted by the user 201, the manufacturer, or the retailer to customize the distance 215 and the angle β to the unique anatomical variations of the user 201. In this manner, the visual output of the display 208 (including focal length, depth, and angle β relative to the eye 207) may be optimized for the user 201 to produce a focused and high-quality image to the user without requiring multiple SKUs of the display portion 202 (including the housing 212, the optical seal 206, or any other component thereof) to accommodate variations in the characteristics of multiple users.

[0051] In some examples, the head-mountable device described herein may include one or more sensors or cameras to detect and determine a topographic map of the user's face, including measurements of the user's anatomical features to form a facial map or identification. In at least one example, the user may use a separate device including a smart phone or other electronic device to determine and generate a facial map. Information associated with this facial map may be linked to a user account or otherwise provided to a manufacturer or retailer. The manufacturer or retailer may adjust the optical seal 206 as needed to provide an optimal distance 215 and angle β of the display 208 relative to the eye 207. In one or more other examples, the user may adjust the optical seal 206 (including the resulting distances 213a and 213b) to adjust the distance 215 and angle β to customize the display portion 202.

[0052] Figure 2 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 2 Examples of equipment, features, components and parts shown.

[0053] Figure 3 A rear perspective view of a display portion 302 of a head-mountable device including a housing 312 and an optical seal 306 is shown. The display portion 302 also includes a first display 308a and a second display 308b. The first display 308a can be configured to direct light toward the user's left eye, and the second display 308b can be configured to direct light toward the user's right eye. The optical seal 306 can include a contact surface 309 that is configured to be pressed against the user's face when the display portion 302 is worn. The optical seal 306 and its contact surface 309 can define various distances 313a, 313b that separate the housing 312 from the user's face, and therefore, as described above, also determine the distance and viewing angle of the displays 308a, 308b relative to the user's eyes.

[0054] Light seal 306 may be configured such that contact surface 309 forms a barrier with the user's face to prevent ambient light external to display portion 302 from being incident on displays 308a and 308b. Figure 3 313a and 313b are labeled between the housing 312 and the user's face, but any number of unique distances between the housing 312 and the user's face may be defined by the light seal 306. That is, in order to optimally position the displays 308a, 308b relative to the user's eyes, the light seal 306 may include different thicknesses, depths, and other dimensions to vary the distance between the user's face and the housing 312.

[0055] In at least one example, the light seal 306 can extend around the inner edge of the housing 312 of the display portion 302 along the periphery. In at least one example, the housing 312 can define a front side 319 and a rear side 321. The housing can define a peripheral edge 323 around the periphery of the rear side 321, and the light seal 306 can extend rearward from the rear side and at or at a position corresponding to the peripheral edge 323. The light seal 306 can extend from Figure 3 The housing 312 is shown extending rearward to define a viewing volume 329, wherein the displays 308a and 308b project light toward the user's eyes. Based on the contact between the user's face and the contact surface 309 of the optical seal 306, ambient light outside the display portion 302 is blocked from entering the viewing volume 329. In at least one example, the contact surface 309 of the optical seal 306 is a continuous, uninterrupted surface that provides a complete barrier to ambient light entering the viewing volume 329. In at least one example, no portion of the contact surface 309 of the optical seal 306 is separated from or not in contact with the user's face.

[0056] Figure 3 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 3 Examples of equipment, features, components and parts shown.

[0057] Figure 4 A user 401 is shown, along with a contact area 414 and four data terminals covering the user's face. The contact area 414 represents an area of ​​the user's face that can be contacted by the various optical seals described herein. The contact area surrounds the user's eyes so that light projected to the user's eyes via one or more devices and displays described herein is isolated from ambient light in the external environment. As shown, the contact area 414 can also extend across the user's nose bridge and be shaped to conform to the facial layout above the nose, on the cheeks, and around the user's eyes to the forehead.

[0058] also, Figure 4 Four contact reference locations 416a-416d are also shown. Figure 4The contact reference positions 416a-416d shown represent approximate locations where an adjustment mechanism that changes the thickness of the optical seal and, therefore, the distance of the display housing relative to the user's face can be positioned. In at least one example, manipulating the adjustment mechanism located at these contact reference positions 416a-416d can be sufficient to adjust the optical seal of the device described herein, and, therefore, the relative position and angle of the display screen of the device described herein, to customize the head-mountable device for a specific user, despite different facial sizes and anatomical features.

[0059] Specifically, in Figure 4 In the example shown, the first reference position 416a and the second reference position 416b may be located on opposite left and right sides of the user's forehead. The third contact reference position 416c and the fourth contact reference position 416d may be located on opposite cheeks of the user on either side of the user's nose. One or more other examples may include contact reference positions of the adjustment mechanism of the optical seal described herein at other locations on the user's face. In addition, one or more examples of the head-mountable device described herein may include less than four adjustment mechanisms associated with less than four contact reference positions. One or more other examples of the head-mountable device described herein may include more than four adjustment mechanisms associated with more than four contact reference positions. Figure 4 Just one non-limiting example of contact reference locations 416a - 416d is shown, illustrating that separate and discrete adjustment mechanisms at separate and discrete contact reference locations 416a - 416d may be used to adjust and customize the head mountable device described herein.

Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein.

[0061] FIG. 5A to FIG. 5CA user 501 is shown wearing a head mountable device including a display portion 502. The display portion 502 may include a housing 512 and a display 508, such as a display screen, disposed on, within, or otherwise coupled to the housing 512. In at least one example, the display portion 502 also includes an optical seal 506 extending from the housing 512 and contacting the user 501. A first portion or upper portion of the optical seal 506 may extend from the housing 512 and contact the user's forehead 503. A second portion or lower portion of the optical seal 506 may extend from the housing 512 and contact the user's cheek 505.

[0062] In at least one example, anywhere the optical seal 506 contacts the user, such as in Figure 5A 505, the optical seal can define a distance separating the housing 512 from the face of the user 501, and thus, due to the coupling between the display 508 and the housing 512, a distance 515 separating the display 508 from the user's eyes 507. For example, a first portion or upper portion of the optical seal 506 can define a first distance 513a separating the housing 512 from the forehead 503 of the user 501. Similarly, a second portion or lower portion of the optical seal 506 can define a second distance 513b separating the housing 512 of the display portion 502 from the cheek 505 of the user 501. In order to optimally position the display 508 relative to the user's eyes 507, the optical seal can include a portion defining a first distance 513a separating the housing 512 from the forehead 503 of the user 501. Figure 5A As indicated in the distance 515 , the first distance 513 a and the second distance 513 b may be the same or different.

[0063] In at least one example, the display portion 502 can include a light seal 506 having a sheath defining an interior volume 518. In one example, the sheath can be a compliant or elastic material that can expand, contract, and elastically return to a resting shape when no force is applied. That is, in at least one example, the light seal 506 can be sized to change the shape of the light seal 506. Figure 5A The display portion 502 may include one or more adjustment spacers or mechanisms 520a and 520b to change the light seal 506 in a manner that changes the first distance 513a and the second distance 513b associated with different portions of the light seal 506. The adjustment mechanisms described herein, including the adjustment mechanisms 520a and 520b, may be referred to as adjustment spacers that adjust the distances 513a and 513b. In at least one example, the adjustment mechanisms 520a and 520b define the first distance 513a and the second distance 513b, respectively.

[0064] In one example, a first adjustment mechanism 520a can be disposed within the interior volume 518 at an upper portion of the light seal 506. A second adjustment mechanism 520b can be disposed in the interior volume 518 of a second or lower portion of the light seal 506. Each adjustment mechanism 520 can include a variable length mechanism coupled to the housing 512 and disposed in the interior volume 518 defined by the light seal 506. The variable length mechanism of the adjustment mechanism can be manipulated to change the overall length of each of the adjustment mechanisms 520a and 520b. Figure 5A Each of the illustrated adjustment mechanisms 520a and 520b can be similar, so that a description of one adjustment mechanism can apply to the other. The adjustment mechanism 520a can alternatively be coupled to the frame 510 of the display portion 502. In one example, the frame 510 can be an extension of the housing 512 or a part of the housing. For another example, the frame 510 can be a separate frame component that is connected to or coupled to the housing 512 and supports the housing 512.

[0065] In at least one example, the adjustment mechanism 520a can be coupled to the frame 510 and extend into the light seal 506. In at least one example, the light seal 506 or a sheath defining its interior volume 518 and the housing 512 can hide the adjustment mechanism 520a or 520b from view. In any case, the adjustment mechanism 520a disposed in the interior volume 518 of the light seal 506 can be coupled to the frame 510 or the housing 512 such that adjustment of the length of the adjustment mechanism 520a changes the distance 513a, and thus changes the distance 515 between the display 508 and the user's eye 507.

[0066] exist Figure 5A In the example shown, the display 508 is positioned at an optimal angle α relative to the line of sight of the user's eye 507 to achieve optimal visual performance of the display portion 502. The display 508 is also located at an optimal distance 515 from the user's eye 507. For purposes of illustration, the angle α and the distance 515 are described herein as optimal, but the distances and angles (including Figure 5A The angle α and distance 515 shown do not necessarily represent the optimal distance and angle for any one user. Instead, the angle α and the distance 515 will be used to illustrate how the adjustment of the adjustment mechanisms 520a and 520b, and therefore the adjustment of the distances 513a and 513b defined by the light seal 506, can be maintained regardless of user anatomical variations.

[0067] For example, Figure 5BThe same display portion 502 of the head mountable device is shown, but worn by a user with different anatomical features (such as cheekbone structure or forehead position). In order to maintain an optimal distance 515 between the display 508 and the user's eyes 507 and to maintain an optimal angle α, Figure 5A The first adjustment mechanism 520a and the second adjustment mechanism 520b may be shortened compared to the adjustment mechanisms 520a and 520b shown in FIG. 5. Thus, the first distance 513a and the second distance 513b separating the housing 512 from the respective portions of the user's face in FIG. 5 may be different from the first distance 513a and the second distance 513b separating the housing 512 from the respective portions of the user's face in FIG. Figure 5A The distances 513a and 513b are shown. Therefore, based on Figure 5B Different anatomical features and sizes of users shown can maintain Figure 5B The optimal distance 515 between the display 508 and the eyes 507 of the user 501.

[0068] It will also be noted that the optimal distance 515 and the optimal angle α may vary from one user to another. Therefore, rather than maintaining the angle α and the distance 515 between users, the adjustment mechanisms 520a and 520b may be used to change the angle α and the distance 515 to achieve optimal use unique to each user.

[0069] Figure 5C Another example of the same display portion 502 being worn by another user 501 is shown. Figure 5C Due to the unique anatomical features and size of the user 501 shown, the first adjustment mechanism 520a has been altered to be longer than the length of the second adjustment mechanism 520b to maintain the optimal distance 515 and angle α of the display 508 for the user 501. Adjustment of the lengths of the adjustment mechanisms 520a and 520b results in corresponding changes in the first distance 513a and the second distance 513b defined by the optical seal 506 that separate the housing 512 and / or frame 510 from various contact reference positions of the optical seal 506 pressed against the user 501. In at least one example, varying the lengths of the adjustment mechanisms 520a and 520b independently of one another can vary the angle α of the display 508 relative to the eye 507 and affect the distance 515.

[0070] In addition to optimizing the position and orientation of the display screen within the device, the adjustment mechanism and adjustable optical seal of the head-mounted device described herein can also be used to change the shape of the optical seal to better conform to the user's face. This improved and consistent contact between the optical seal and the user's face can also distribute force more evenly, so that injuries caused by collision or falling with the head-mounted device can be reduced. The adjustment mechanism shown in the accompanying drawings can also take other forms, including adjustable spacers, screws, or other variable length mechanisms to expand or reduce the thickness or distance of the optical seal between the housing or frame of the display portion and the user's face. As described above, the adjustments described with reference to the adjustment mechanism and the variable length mechanism can be performed by the user, retailer, and / or manufacturer to optimize each head-mounted device for the unique anatomical features of each user without the need for multiple or excessive SKUs.

[0071] FIG. 5A to FIG. 5C Any of the features, components and / or parts shown (including their arrangements and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including their arrangements and configurations) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. FIG. 5A to FIG. 5C Examples of equipment, features, components and parts shown.

[0072] Figure 6 A side cross-sectional view of another example of a display portion 602 of a head mountable device is shown. The display portion 602 can include a housing 612 and a display 608 coupled to the housing 612 via a frame 610. The display 608 can be connected to the frame 610. In addition, the display portion 602 can include a light seal 606 extending rearwardly from a rear surface of the display portion 602 and surrounding a rear peripheral edge of the display portion 602. In at least one example, the housing 612 can define an exterior surface of the display portion 602, the housing 612 can be coupled to the frame 610, and the adjustment mechanisms 620a and 620b can be coupled to the frame 610.

[0073] In such an example, the adjustment mechanisms 620a and 620b may extend directly from the frame 610 and contact the user's face to adjust the distance between the display 608 and the user's eyes. When the adjustment mechanisms 620a and 620b connected to the frame 610 are changed, the light seal 606 may be formed of a compliant, soft or elastic material that compresses or expands accordingly to extend from the housing 612 to the user's face. In this way, when the adjustment mechanisms 620a and 620b are changed to accommodate the user, the light seal 606 can maintain consistent and uninterrupted contact with the user's face to block light.

Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein.

[0075] Figure 7 A side cross-sectional view of another example of a display portion 702 of a head mountable device is shown. The display portion 702 may include a housing 712 and a display coupled to the housing 712 via a frame 710. The display 708 may be connected to the frame 710. In addition, the display portion 702 may include a light seal 706 extending rearwardly from a rear surface of the display portion 702 and surrounding a rear peripheral edge of the display portion 702. In at least one example, the housing 712 may define an exterior surface of the display portion 702. The housing 712 may be coupled to the frame 710 and the adjustment mechanisms 720a and 720b may be coupled to the housing 712 but not within the interior volume of the light seal 706. In such an example, the adjustment mechanisms 728 and 720 may be disposed elsewhere on the housing 712. When the display portion 702 is worn, the light seal 706 can be formed of a soft or elastic material that expands and contracts between the housing 712 and the user's face so that the adjustment mechanisms 720a and 720b can be changed and the light seal 706 can maintain contact extending between the housing 712 and the user's face and block light.

[0076] Figure 7 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 7 Examples of equipment, features, components and parts shown.

[0077] Figure 6 and Figure 7 Examples of adjustment mechanisms 620a and 620b and 720a and 720b are shown, which can be located at different locations of the display portion 602, 702 and cause adjustments in the light seal 606, 706 as the adjustment mechanism is changed. The adjustment mechanism described so far includes a variable length mechanism that can be changed to change the length of the adjustment mechanism and thus change the thickness or other dimensions of the light seal. However, other forms of adjustment mechanisms and components that change the thickness, distance or other dimensions of the light seal described herein are also contemplated.

[0078] For example, the adjustment mechanism described herein may include an adjustable screw, and the adjustable screw may be threaded in one way or another to increase or decrease its length. Another example may include an internal volume of the light seal that may be inflated or deflated to change different areas or portions of the light seal. In one example, the light seal may be formed of a material that can be molded to the user's face when heated and then cooled to set a contour that complements the user's facial contour. In one example, the adjustment mechanism may include a track with a spring release. Other mechanisms for changing the shape or size of the light seal described herein are also contemplated.

[0079] like Figure 8 As shown, in addition to or as an alternative to the adjustment mechanisms described herein, one or more examples of an optical seal for a display portion of a head-mounted device may include one or more spacers or gaskets 822 that increase the profile, shape, thickness, or other features and dimensions of the optical seal 806. Figure 8 A side view of another example of a display portion 802 of a head mountable device is shown. The display portion 802 can include a housing 812 and a display 808. As shown, an optical seal 806 that conforms to the contours of a user's face and makes consistent and uninterrupted contact therewith can extend from the housing. In at least one example, a gasket 822 can be sized, shaped, and otherwise formed to change and control the surface topography of the optical seal to match the surface topography of the user's face.

[0080] As described above with reference to other adjustment mechanisms of the light seal shown in other figures, Figure 8 The spacer 822 can be used in addition to or instead of such an adjustment mechanism. In any case, the spacer 822 can change the various distances 813a and 813b of light between the housing 812 and the user's face. In this way, the spacer 822 can function like other adjustment mechanisms described herein to change the distance and angle of the display 808 relative to the user's eyes to achieve optimal performance.

[0081] The gasket 822 can be custom formed based on the identified morphology or morphology map of the user's face detected or measured by the head-mounted device or one or more other electronic devices. The morphology can also be manually matched using measurements taken by the user, retailer, or manufacturer. In such an example, the display portion 802 including the housing and the light seal 806 can be a common SKU for all users, while the gasket 822 can be customized or part of a limited number of SKUs with different morphologies to cover a wide range of anatomical variations for different users. In this way, manufacturing complexity and cost can be reduced by only requiring custom gaskets 822 or selecting a limited number of gasket SKUs.

[0082] Fig. 9 A side view of another example of a display assembly 902 including a housing 912, a display 908 disposed within the housing, and an optical seal 906 is shown. A gasket 922 (which may be similar to Figure 8 A custom shim (eg, shim 822 as shown) may be disposed within the interior volume of light seal 906 such that shim 922 is hidden from view and the contour and topography of the contact surface of light seal 906 is controlled from within light seal 906 .

[0083] In addition, as described above with reference to other adjustment mechanisms of the light seal shown in other figures, Fig. 9 The spacer 922 can be used in addition to or instead of such an adjustment mechanism. In any case, the spacer 922 can change the various distances 913a and 913b of the light seal 906 between the housing 912 and the user's face. In this way, the spacer 922 can function like other adjustment mechanisms described herein to change the distance and angle of the display 908 relative to the user's eyes to achieve optimal performance.

[0084] Figure 8 and Fig. 9 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 8 and Fig. 9 Examples of equipment, features, components and parts shown.

[0085] like Fig.10 As shown, in addition to or as an alternative to the adjustment mechanisms described herein, one or more examples of an optical seal for a display portion of a head-mounted device may include two or more spacers or gaskets 1022a, 1022b that increase the profile, shape, thickness, or other features and dimensions of the optical seal 1006. Fig.10 A side view of another example of a display portion 1002 of a head mountable device is shown. The display portion 1002 can include a housing 1012 and a display 1008. As shown, an optical seal 1006 that conforms to the contours of a user's face and makes consistent and uninterrupted contact therewith can extend from the housing. In at least one example, a gasket 1022 can be sized, shaped, and otherwise formed to change and control the surface topography of the optical seal to match the surface topography of the user's face.

[0086] As described above with reference to other adjustment mechanisms of the light seal shown in other figures, Fig.10The spacers 1022a and 1022b can be used in addition to or instead of such an adjustment mechanism. In any case, the spacers 1022a and 1022b can change the various distances 1013a and 1013b between the housing 1012 and the user's face. In this way, the spacers 1022a and 1022b can function like other adjustment mechanisms described herein to change the distance and angle of the display 1008 relative to the user's eyes to achieve optimal performance.

[0087] The gaskets 1022a and 1022b can be custom-formed based on the identified morphology or morphology map of the user's face detected or measured by the head-mounted device or one or more other electronic devices. The morphology can also be manually matched using measurements taken by the user, retailer, or manufacturer. In such an example, the display portion 1002 including the housing and the optical seal 1006 can be a common SKU for all users, while the gaskets 1022a and 1022b can be customized or part of a limited number of SKUs with different morphologies to cover a wide range of anatomical changes for different users. In this way, manufacturing complexity and cost can be reduced by only requiring custom gaskets 1022a and 1022b or selecting a limited number of gasket SKUs.

[0088] Fig.11 A side view of another example of a display assembly 1102 including a housing 1112, a display 1108 disposed within the housing, and an optical seal 1106 is shown. Two separate gaskets 1122a, 1122b (which may be similar to Fig.10 The spacers 1022a and 1022b shown (custom-made for the light seal 1106 ) may be disposed within the interior volume of the light seal 1106 such that the spacers 1122a and 1122b are hidden from view and the contour and topography of the contact surface of the light seal 1106 is controlled from inside the light seal 1106 .

[0089] Again, as described above with reference to other adjustment mechanisms of the light seal shown in other figures, Fig.11 The spacers 1122 of the embodiment of the present invention can be used in addition to or instead of such an adjustment mechanism. In any case, the spacers 1122a and 1122b can change the various distances 1113a and 1113b between the housing 1112 and the user's face. In this way, the spacers 1122a and 1122b can function like other adjustment mechanisms described herein to change the distance and angle of the display 1108 relative to the user's eyes to achieve optimal performance.

[0090] Fig.10 and Fig.11Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Fig.10 and Fig.11 Examples of equipment, features, components and parts shown.

[0091] Fig.12 An example of a portion of a display portion 1202 is shown, which includes a frame 1210 and a track 1224 extending backward from the frame 1210 and connected to the frame 1210 via a plurality of adjustment mechanisms 1220a-1220f. The track 1224 and the frame 1210 may be surrounded by a sheath or other component of the light seal 1206 so that the frame 1210 and / or the track 1224 and / or the adjustment mechanism 1220a-1220f are hidden and not visible. In at least one example, the track 1224 may form a contact surface that is configured to press against the user's face when the head-mounted device is worn. In one example, the display portion 1202 may include a plurality of separate and different adjustment mechanisms 1220a, 1220b, 1220c, 1220d, 1220e, and 1220f. The adjustment mechanisms 1220a-1220f may be collectively referred to as adjustment mechanisms 1220.

[0092] Each adjustment mechanism 1220 may be similar to the other adjustment mechanisms such that a description of one adjustment mechanism may apply to all adjustment mechanisms 1220. Each adjustment mechanism 1220 may extend from the frame 1210 to the track 1224 and include a variable length mechanism. In this manner, a first, second, third, fourth, fifth, sixth, and any other number of adjustment mechanisms 1220 may be individually altered to adjust the distance 1213 from the frame to the user's face. In this manner, the distance 1213 may be altered to varying degrees at different points along the track 1224 relative to the frame 10, corresponding to the position of each adjustment mechanism 1220. The length of each adjustment mechanism 1220 may be individually altered by a user, retailer, or manufacturer to change the shape and topography of the track 1224 within the optical seal 1206 to match the shape and topography of individual user anatomical features. In this manner, the optical seal 1206 may be manufactured to a desired size and shape. Fig.12 A single SKU of display portion 1202 is shown to simplify cost and manufacturing complexity while providing a unique configuration for each user to optimize display position and orientation as described herein.

[0093] The position of each adjustment mechanism 1220 may correspond to certain portions of the light seal 1206, wherein each portion of the light seal 1206 corresponds to a distance 1213b between the frame 1210 or the housing of the display portion 1202 and the user's face. For example, the first adjustment mechanism 1220a may correspond to a first upper portion of the light seal 1206 that defines a first distance 1213a between the frame 1210 and the user's face, and the second adjustment mechanism 1220b may correspond to a second upper portion of the light seal 1206 that defines a second distance 1213b between the frame 1210 and the user's face. In addition, the third adjustment mechanism 1220c or 1220d may correspond to a first lower portion of the light seal 1206 and define a third distance 1213c between the frame 1210 and the user's face, and the fourth adjustment mechanism 1220e or 1220f may correspond to a second lower portion of the light seal 1206 and define a fourth distance 1213d between the frame 1210 and the user's face. Each distance 1213 may be changed to accommodate the user.

[0094] The optical seals and head-mountable device adjustment mechanisms described herein may include multiple mechanisms, including multiple variable length mechanisms, pivot mechanisms, screws, spacers, spacers, etc., which may be collectively referred to as a single adjustment mechanism. Fig.12 In the embodiment, the adjustment mechanisms 1220a-1220f can be considered to be each part of a single adjustment mechanism that is configured to change the shape, curvature, or various distances from the housing of the light seal 1206 and the track 1224 that presses against the user's face during use. Another example includes FIG. 5A to FIG. 5C , which shows a first adjustment mechanism 520a and a second adjustment mechanism 520b. These adjustment mechanisms 520a and 520b can be referred to as a single adjustment mechanism that changes the size and shape of a single light seal 506 extending from the housing 512.

[0095] Fig.12 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Fig.12 Examples of equipment, features, components and parts shown.

[0096] Fig.13 Another example of a display portion 1302 of a head mountable device is shown. Fig.13A top view of a display portion 1302 is shown including a frame 1310 and a light seal 1306 extending rearwardly from the frame 1310. As described above with respect to other examples, the frame 1310 can be part of the housing, extend from the housing, or the light seal 1306 can extend directly from the housing coupled to the frame 1310. Fig.13 In the illustrated example of , the adjustment mechanisms 1320a and 1320b extend from the frame within the light seal 1306 (eg, extend within an interior volume defined by the light seal 1306).

[0097] In at least one example, the first adjustment mechanism 1320a and the second adjustment mechanism 1320b can be similar, respectively, so that the description of one adjustment mechanism applies to both. The first adjustment mechanism 1320a may include: a base 1327, which is coupled to the frame 1310 via a variable length mechanism 1326; and a member 1328, which is fixed to the frame 1310 at one end and rotatably fixed to the base 1327 at a second end via a pivot mechanism 1330. In at least one example, the variable length mechanism 1326 can be adjusted to increase or decrease its length so that the base 1327 can be rotated about 1330 to change the angle of the base 1327 relative to the frame 1310. The change in the angle can adjust the topography of the contact surface 1309 of the optical seal 1306 to better conform to the user's face and adjust the position of one or more components of the display portion 1302 (including the display screen) relative to the user's eyes.

[0098] Rotation of the base 1327 about the pivot mechanism 1330 can also adjust the distance 1313 between the frame content or housing of the display portion 1302 and the contact surface 1309 of the light seal 1306. In addition, in at least one example, the member 1328 can also be adjustable in length to further provide the base 1327 with the freedom to adjust as needed.
