Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 585,563, filed on September 26, 2023, entitled “ELECTRONIC DEVICE WITH LIGHTWEIGHT FACIAL INTERFACE,” the entire disclosure of which is hereby incorporated by reference into this document. Technical Field

[0003] The embodiments described herein generally relate to electronic devices. More particularly, embodiments of the present invention relate to face engaging portions of 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. Such head-mounted devices may include various components, such as displays, viewing frames, lenses, optical components, batteries, motors, speakers, and other components. These components can operate together to provide an immersive user experience. Specifically, a head-mounted device may include components that help provide a distraction-free environment by at least partially blocking or enclosing the external environment (e.g., ambient light). This can be a challenging design aspect because users of head-mounted devices have different head sizes, head shapes, and contours of facial features. Therefore, there is a need for a head-mounted device with a lightweight and highly conformable facial joint. Summary of the invention

[0005] In at least one example, a head-mountable device may include: a display frame; an optical component disposed within the display frame; a facial joint connected to the display frame and having a lattice structure; and a strip connected to the display frame.

[0006] In one example of the head-mountable device, the lattice structure may have a geometric shape or pattern configuration of an auxetic structure, a honeycomb structure, an abutting spherical structure, or a custom structure based on stress-strain mapping.

[0007] In one example of the head-mountable device, the grille structure may include an elastomeric material.

[0008] In one example of the head mountable device, the grille structure may include a first material and a second material.

[0009] In one example, the head mountable device may include an insert embedded within the grille structure.

[0010] In one example of the head mountable device, a portion of the grille structure may include a first set of directional characteristics and a second set of directional characteristics different from the first set of directional characteristics.

[0011] In one example, the head mountable device may include a rigid buffer connected to the display frame and positioned between the display frame and the face interface. The rigid buffer may define a fixed gap between the optical component and the face interface.

[0012] In one example of the head-mountable device, the grille structure is a first grille structure and further includes a second grille structure that is interchangeable with the first grille structure. In some examples, the first grille structure and the second grille structure correspond to the rigid buffer.

[0014] In one example of the head-mountable device, the first portion of the grille structure may include a base portion. The second portion of the grille structure may include a custom portion.

[0015] In at least one example, a wearable device may include: a display housing; a display positioned within the housing; and a face interface connected to the display housing. The face interface may include a layered material having a repeating geometric arrangement, the layered material having a first portion and a second portion, the first portion having a first set of directional characteristics, the second portion having a second set of directional characteristics different from the first set of directional characteristics.

[0016] In one example of the wearable device, the repeating geometric arrangement may include C-shaped ribs.

[0017] In one example of the wearable device, the repeating geometric arrangement may include a set of vertical beams positioned substantially parallel to a contact surface of the facial engaging portion configured to engage a human face.

[0018] In another example of the wearable device, the set of vertical beams is a first set of vertical beams, and the repeating geometric arrangement may include a second set of vertical beams stacked relative to the first set of vertical beams. The first set of vertical beams and the second set of vertical beams may be configured to bend laterally in response to a force.

[0020] In at least one example, a wearable electronic device may include: a head-mountable display; an insert; and a facial interface comprising a combination of integrally connected layers defining an ordered pattern disposed around a portion of the insert.

[0021] In one example of the wearable electronic device, the insert may include a magnet, an attachment member, or a structural member.

[0022] In one example of the wearable electronic device, the insert can be embedded in the facial engaging portion.

[0023] In one example of the wearable electronic device, the face engaging portion can be extended over the insert.

[0024] In one example of the wearable electronic device, the face engaging portion includes a first material and the insert may include a second material different from the first material. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover substitutions, modifications and equivalents that may be included within the spirit and scope of the described embodiments defined by the appended claims.

[0046] The following disclosure relates generally to electronic devices, and specifically to head-mounted electronic devices (or head-mounted devices). In at least one example, a head-mounted device may include a viewing frame and a fixed arm (or strap / band) extending from the viewing frame. Examples of head-mounted electronic devices may include virtual reality or augmented reality devices that include optical components. In the case of an augmented reality device, optical glasses or frames may be worn on a user's head so that an optical window, which may include a transparent window, lens, or display, may be positioned in front of the user's eyes. In another example, a virtual reality device may be worn on the user's head so that a display screen is located in front of the user's eyes. The viewing frame may include a housing (e.g., a display housing or a display frame) or other structural components that support optical components (e.g., a lens or display window) or various electronic components.

[0047] In addition, the head-mounted electronic device may include one or more electronic components for operating the head-mounted electronic device. These components may include any components that the head-mounted electronic device uses to produce a virtual or augmented reality experience. For example, the electronic components may include one or more projectors, waveguides, speakers, processors, batteries, circuit components including wires and circuit boards, or any other electronic components used in the head-mounted device to deliver enhanced or virtual reality visual, sound, and other outputs. Various electronic components may be disposed in an electronic component housing. In some examples, various electronic components may be disposed in or attached to one or more of a display frame, an electronic component housing, or a fixed arm.

[0048] More specifically, the present disclosure relates to a face joint of a head-mountable device (HMD). A face joint refers to a seal sandwiched between the HMD and the user's face. In more detail, the following disclosure relates to a face joint that is lightweight and conformable to optimize the user experience. Such a lightweight and conformable face joint allows the HMD to comfortably fit the user's face and accommodate the user's unique head size and shape.

[0049] Lightweight and conformable joints can be achieved via additive manufacturing (e.g., three-dimensional (3D) printing), whereby an object is manufactured by adding and combining successive thin layers of material. Additive manufacturing can enable the manufacture of lightweight and flexible (in some cases, with negligible weight and stiffness) facial joints, for example, by selecting various materials, grid structures, and grid densities.

[0050] In addition, additive manufacturing can allow for easy and cost-effective customizability of the facial joint. The facial joint can be manufactured with various shapes, contours, and stiffnesses to accommodate various head shapes, sizes, and facial contours of different users. In some examples, at least a portion of the facial joint (e.g., the outer, skin-facing layer) can be customized on a user-by-user basis for more control and a custom fit for a specific user.

[0051] In at least one example, the facial joint disclosed herein may be independent and separate from the structural components of the head-mounted device. For example, the facial joint of the present disclosure may be connected to or at least in contact with a rigid buffer, which may help maintain the structural integrity of the head-mounted device. In such examples, the size and shape of the facial joint may be set to accommodate one or more rigid buffers. However, although the facial joint is connected to or in contact with the rigid buffer, the facial joint may still be functionally disengaged from the rigid buffer, so that the facial joint may have increased conformability and help provide a better fit and better comfort to the user.

[0052] References below Figures 1 to 11B These embodiments and other embodiments are discussed. However, those skilled in the art will readily appreciate that the detailed descriptions of these figures given herein are 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 comprising one of each listed option (e.g., only one first option, only one second option, only one third option), a plurality of a single listed option (e.g., two or more first options), two options simultaneously (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0053] Figure 1 A top view profile of a head mountable device 100 worn on a user's head 101 is shown according to one example. Although the present systems and methods are described in the context of head mountable device 100, the systems and methods may be used with any wearable device, wearable electronic device, or any device or system that can be physically attached to a user's body, but are particularly relevant to electronic devices worn on a user's head.

[0054] The head mountable device 100 may include an optical component 102 (e.g., one or more optical lenses or display screens in front of the user's eyes). The optical component 102 may include a display / screen for presenting an augmented reality visualization, a virtual reality visualization, or other suitable visualization. The optical component 102 may be part of an optical module, which may include sensors, cameras, light emitting diodes, an optical housing, a protective glass, sensitive optical elements, etc. The optical component 102 may be disposed on or within a display frame 105. In other words, the display frame 105 may be a display housing that houses the optical component 102. For example, a display of the optical component 102 may be positioned within the display housing.

[0055] The head-mountable device 100 may include arms, such as arm 108 and arm 110. Arms 108, 110 may secure the head-mountable device 100 to the user's head 101. Arms 108, 110 have proximal ends 107 and distal ends 108. Proximal end 107 is connected to display frame 105. Arms 108, 110 are connected to display frame 105 and extend distally toward the back of the head. Arms 108, 110 are configured to secure the display in a certain position relative to the user's head 101 (e.g., so that the optical component 102 is maintained in front of the user's eyes). For example, arms 108, 110 extend over the user's ears 112. In some examples, arms 108, 110 are placed on the user's ears 112 to secure the head-mountable device 100 via friction between arms 108, 110 and the user's head 101. For example, the arms 108, 110 can apply opposing pressure to the sides of the user's head 101 to secure the head mountable device 100 to the user's head 101. In at least one example, the strap 103 can be connected to the distal ends of both arms 108, 110. The strap 103 can provide additional support to secure the head mountable device 100 to the user's head 101, for example, by wrapping around the back of the user's head 101. The strap 103 can compress the head mountable device 100 against the user's head 101. In a specific example, the strap 103 is connected to at least the frame or face interface 104 of the display 102.

[0056] The head mountable device 100 may include an electronics box 116. Figure 1 As depicted, the electronics box 116 can be disposed on the arm 108. However, in other examples, the electronics box 116 can be disposed on the arm 110, the strap 103, the display frame 105, or elsewhere on the head mountable device 100. The electronics box 116 can include various electronic components, such as a controller, a microcontroller, a processor, memory, a battery, a power port, and the like.

[0057] The head mountable device 100 includes a face engaging portion 104. The face engaging portion 104 is at least partially disposed on an inner surface of the head mountable device 100. As used herein, an "inner surface" refers to an outer surface of the head mountable device 100 that is oriented to face (or contact) a person's face or skin. In contrast, as used herein, an "outer surface" refers to an outer surface of the head mountable device 100 that faces outward toward the surrounding environment.

[0058] As used herein, the term "face joint" refers to a portion of the head-mounted device 100 that engages the user's face via direct contact. Specifically, the face joint includes a portion of the head-mounted device 100 that adapts to (e.g., presses against) an area of ​​the user's face. For example, the face joint may include a flexible (or semi-flexible) facial track that spans the forehead, surrounds the eyes, contacts the zygomatic region and maxillary region of the face, and bridges the nose. In addition, the face joint may include various components that form a structure, a band, a cover, a fabric, or a frame of the head-mounted device, which are disposed between the display frame 105 and the user's skin. In a specific implementation, the face joint may include a seal (e.g., a light seal, an environmental seal, a dust seal, an air seal, etc.). It should be understood that in addition to a complete seal, the term "seal" may also include a partial seal or a suppressor (e.g., when the head-mounted device is worn, a partial face joint blocks some ambient light, and a complete face joint blocks all ambient light).

[0059] In some examples, the facial joint 104 may include a grid structure, as will be described with reference to the remaining figures. As used herein, a grid structure refers to a staggered design, a grid design, a framework, a three-dimensional arrangement, or a repeating pattern that can fill a volume and / or conform to a surface. For example, a grid structure may include one or more beams, surfaces, plates, or units that fit together following an ordered or repeating pattern / geometric arrangement (e.g., a symmetrical pattern, a grid pattern, a fixed shape pattern, a fractal, a spiral pattern, a zigzag pattern, a tessellation pattern, a wave pattern, a crystal pattern, a mathematical pattern, or a random pattern). The grid structure may have various material properties, including directional material properties. For example, the grid structure may include one or more portions having isotropic material properties and / or one or more portions having anisotropic material properties. In a specific example, the grid structure includes material properties (e.g., modulus, stiffness, beam diameter, unit cell density, anisotropy, etc.) that can be tuned or adjusted according to various design factors. In these or other examples, the grid structure can be manufactured in various ways, including via additive manufacturing or 3D printing.

[0060] In some examples, the facial joint may include a combination of integrally connected layers (e.g., layers defining the above-described ordered pattern). As used herein, the term integrally connected layers refers to two or more layers that are fixedly or non-removably connected to each other. Examples of integrally connected layers may include stacked layers, printed layers (e.g., 3D printed layers), adhesive layers, bonding layers, welded layers, molded layers, etc. In the example of 3D printing, the integrally connected layers may include rows, steps, filaments, ribs, etc. that are added one on top of another (i.e., layer by layer) during the printing process. In some examples, the integrally connected layers may be visible (e.g., as seams, ridges, lines, loops, or wood-like particles). In other examples, the integrally connected layers may be visually hidden or obscured by various methods (e.g., sanding, painting, coating, sandblasting, surface fusion / melting thin outer layers, etc.).

[0061] The face engaging portion 104 may be manufactured via additive manufacturing (e.g., 3D printing) to have a geometric shape or pattern configuration of an auxetic structure (e.g., a structure that expands in a perpendicular direction when stretched in one direction), a honeycomb structure, a contiguous spherical structure, etc. The face engaging portion 104 may be manufactured using elastomeric materials (e.g., materials that return to their original shape after being stretched), multiple materials, anisotropic materials, etc. Additive manufacturing may enable a wide range of customizability of the face engaging portion to accommodate unique head sizes, head shapes, and facial contours.

[0062] In at least one example, the head-mounted device may include one or more rigid buffers (e.g., buffer 106). As used herein, the term "rigid buffer" refers to a structural column, support, rear stop, bulwark, absorber, buffer, column, or block. In these or other examples, the rigid buffer may be fixed in position relative to other components of the head-mounted device 100. Specifically, the rigid buffer may include a hard, rigid, or hardened material (e.g., for resisting impact forces or bending moments, transferring applied loads, or providing a fixed reference). In some examples, the rigid buffer includes a metal material (e.g., aluminum), an engineered plastic material, a fiber-reinforced plastic material, etc. Therefore, in a particular example, the buffer 106 may include a structural column that can extend from the display frame 105. The buffer 106 may also be adjacent to and / or at least partially embedded in the facial joint 104.

[0063] In more detail, the bumper 106 can be connected to the display frame 105 and positioned between the display frame 105 and the face engaging portion 104. The face engaging portion 104 can be connected to the display frame 105. In some examples, the bumper 106 defines a fixed gap between the optical component 102 and the face engaging portion 104.

[0064] Figure 1Any 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. Figure 1 Examples of devices, features, components and parts are shown. FIG. 2A to FIG. 2B Provides additional details of the head-mountable device.

[0065] FIG. 2A to FIG. 2B 1 and 2 show side and front view profiles of an example of a head mountable device 100, respectively. As described above, the head mountable device 100 includes an optical component 102, a display frame 105, a facial interface 104, and a buffer 106. FIG. 2A to FIG. 2B As shown, the face engaging portion 104 may surround the eyes 201, bridge the nose 202, span the forehead 203, and contact the zygomatic region 205 and the maxillary region 209 of the face.

[0066] As used herein, the term "frontal region" refers to the region of a human face between the eyes and the scalp of a person. Additionally, the term "zygomatic region" refers to the region of a human face corresponding to the zygomatic structure of a person. Similarly, the term "maxillary region" refers to the region of a human face corresponding to the maxillary structure of a person.

[0067] FIG. 2A to FIG. 2B 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 and 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. 2A to FIG. 2B The following are examples of equipment, features, components and parts shown. FIG. 3A to FIG. 3C Additional details of a facial joint manufactured via additive manufacturing are described.

[0068] FIG. 3A to FIG. 3C 1 shows a top view, a rear view, and a cross-sectional view of a head mountable device 300 having a face joint 304 including a grille structure 311 according to one example. As used herein, a top view refers to a view of the head mountable device 300 viewed from the top of the head 101, a rear view refers to a view of the head mountable device 300 viewed from behind the head 101, and a cross-sectional view is a view along the top of the head 101. Figure 3B Although not all components are shown, the head mounted device 300 and Figures 1 to 2B The head mountable device 100 is the same or similar, as indicated by similar reference numerals.

[0069] In at least one example, the head mountable device 300 includes a rigid buffer 306. The buffer 306 can be connected to the display frame 105 and positioned between the display frame 105 and the face interface 304 connected to the display frame 105. The buffer 306 can be a rigid or non-flexible component that defines a fixed gap 313 between the optical component 102 and the face interface 304. For example, at least a portion of the buffer 306 can be positioned between the optical component 102 and the face interface 304 so that the face interface 304 is prevented from contacting the optical component 102 even when compressed by the head 101.

[0070] The grid structure 311 may be a 3D printed grid structure, and FIG. 3A to FIG. 3C 311 is cross-hatched. The grid structure 311 can be manufactured to have various characteristics, such as to accommodate a user's specific head shape, head size, and facial contours. As will be further described with reference to the remaining figures, the grid structure 311 can have a geometric shape or pattern configuration of an auxetic structure, a honeycomb structure, a contiguous spherical structure, or a customized structure based on stress / strain mapping. In some examples, the grid structure 311 can include a combination of the above-listed or other grid structures.

[0071] In at least one example, the grid structure 311 may include an anisotropic grid structure. Thus, at least a portion of the grid structure 311 may include a first set of directional characteristics and a second set of directional characteristics that are different from the first set of directional characteristics. In other words, the anisotropic grid structure may exhibit different characteristics along different directions relative to the structure. The anisotropic grid structure may provide rigidity in one or more directions to the facial joint 304 while being compressible and conformable in other directions. In one example, the facial joint 304 may be rigid along the top to bottom direction and the side to side direction of the head 101 to prevent the facial joint 304 from sagging when the head-mounted device is worn by the user. Additionally or alternatively, the facial joint 304 may be compressible and conformable along the front-to-back direction of the head 101, thereby allowing the facial joint 304 to adapt to the user's specific head shape and facial contours.

[0072] In at least one example, the lattice structure can include an elastomeric material. An elastomeric material can be characterized by its ability to return to its original configuration after an applied deforming stress (force) is removed.

[0073] like Figure 3BAs shown, in some examples, the face engaging portion 304 can span substantially along the outer perimeter of the display frame 105. The face engaging portion 304 can contact the user's face and can at least partially surround the buffer 306. The buffer 306 can be located between the face engaging portion 304 and the display frame 105 to define a fixed gap 313 between the user's face and the optical component 102.

[0074] Although shown as being distributed along the perimeter of the face engaging portion 304, in some examples, the buffer 306 may have a different configuration. In one example, the buffer 306 may be located only corresponding to the forehead 203 ( FIG. 2A to FIG. 2B ), the zygomatic region 205, or the maxillary region 209. In other examples, the bumper 306 may be located at an area corresponding to the forehead 203 (shown in Figure 2A to Figure 2B In certain embodiments, the bumper 306 is positioned at the center and oblique regions of the forehead 203 and at the maxillary region 209.

[0075] Although shown as having four buffers 306, in other examples, the head mountable device 300 can have more or fewer buffers, such as one, two, three, five, six, etc. In some examples, the buffer can be continuous and can extend along the perimeter of the head mountable device along the face joint. The configurations of buffers listed above are examples and are not intended to be a fully inclusive list of possible configurations.

[0076] FIG. 3A to FIG. 3C 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. Likewise, any of the features, components, and / or parts shown and 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. 3A to FIG. 3C The following are examples of devices, features, components and parts shown. Figure 4 to Figure 1 1 describes additional details of the internal structure of the face joint manufactured via additive manufacturing. Specifically, reference is made to the mechanical connection between the face joint and the bumper for details. Figure 4 Give a description.

[0077] Figure 4 4 shows a top view of a head mountable device 400 with engagement mechanisms 414 and 418 according to one example. Although not all components are necessarily shown, the head mountable device 400 and FIG. 3A to FIG. 3CThe head mountable device 400 may be the same or similar to the head mountable device 300, as indicated by similar reference numerals. For example, the head mountable device 400 may include an optical component 102, a display frame 105, a facial interface 404, and a buffer 406. For clarity of the following description, Figures 4 to 9 A Cartesian (rectangular) coordinate system is indicated in. The Cartesian coordinate system indicates the X direction as from "side to side" of the user's head 101, the Y direction as from "front to back" of the user's head 101, and the Z direction as from "top to bottom" of the user's head 101.

[0078] In at least one example, face joint 404 can include engagement mechanism 414. Similarly, bumper 406 can include engagement mechanism 418 configured to receive engagement mechanism 414. Engagement mechanisms 414 and 418 can be coupled to prevent translation or displacement of face joint 404 relative to bumper 406 in an X-direction (e.g., from side to side relative to user's head 101) and / or in a Z-direction (e.g., from top to bottom relative to user's head 101).

[0079] The engagement mechanisms 414 and 418 may include protrusions and grooves adapted relative to each other. Additionally or alternatively, the engagement mechanisms 414 and 418 may include other mating features, interlocking features, or attachment features, such as snaps, magnets, hook and loop fasteners, or other fasteners. Adhesives, etc. Furthermore, the engagement mechanisms 414 and 418 can be configured to be temporary, such that the face engagement portion 404 can be removed and / or interchanged, or can be configured to be permanent.

[0080] In the case where the face engaging portion 404 is removable from the bumper 406, the grid structure 311 may be interchanged with a grid structure of a different size. Each of the grid structure and the different structures may correspond to the size and shape of the rigid bumper 406. For example, a face engaging portion having a larger grid structure may require a larger bumper and / or engagement mechanisms 414 and 418 in order to be secured.

[0081] In at least one example, the face engaging portion 404 comprises a single-piece unit, such as Figure 4 As described in Figure 5 In this case, the face joint 404 can be additively manufactured using a single material having a single grid structure. The single-piece unit can be continuous from side to side and from top to bottom.

[0082] In at least one example, a portion of grille structure 411 may be an articulated portion. For example, grille structure 411 may be attached or fixed to at least one of bumper 406 or display frame 105. When a compressive force is applied, for example, from user's head 101, grille structure 411 may rotate relative to display frame 105 to accommodate the user's facial contour. In some examples, face joint 404 may include a structure that may break or snap during initial use of head mountable device 400, thereby allowing the articulated portion to articulate and move flexibly in response to pressure on the user's face.

[0083] Figure 4 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. Figure 4 Examples of devices, features, components and parts are shown. Figure 5 Additional details related to facial joints having multiple materials are described.

[0084] Figure 5 5 shows a top view of a head mountable device 500 having a face interface 504 including a first material 513 and a second material 515 according to one example. Although not all components are necessarily shown, the head mountable device 500 and Figure 4 The head mountable device 500 may be the same or similar to the head mountable device 400, as indicated by similar reference numerals. For example, the head mountable device 500 may include the optical component 102, the display frame 105, and the buffer 406. The head mountable device 500 may include a face joint 504 having a grid structure, the grid structure including a first portion having a first material 513 and a second portion having a second material 515.

[0085] In at least one example, the first portion of the grille structure includes a standard base 520. The standard base 520 can be standardized between one or more head-mountable devices. For example, each head-mountable device 500 can be manufactured to have the same standard base 520. Figure 4 In the head mountable device 400, the standard base 520 can be removably or permanently fixed to the buffer 406. The standard base 520 can provide structural support, which can at least partially define the face joint 504. The term "standard base" can refer to a portion of the face joint 504 that is a base portion, a common portion, or a common portion that is the same underlying portion of all face joints.

[0086] In at least one example, the second portion of the grille structure includes a customized portion 522. A "customized portion" may include a customized portion, a user-specific portion, a fitted portion, a personalized portion, a made-to-order portion, a predetermined portion, a sized portion (e.g., small, medium, large), etc. The customized portion 522 may be customized between one or more head-mountable devices. For example, each head-mountable device 500 may be manufactured to have a unique customized portion 522. The customized portion 522 may be more flexible or more conformable (e.g., compared to the standard base 520) to accommodate the unique head size, shape, and / or facial contour of the head 101. By making the customized portion 522 customizable, the head-mountable device 500 may be more efficiently and cost-effectively customized to accommodate the heads of individual users (rather than customizing the entire facial joint 504). In one example, the customized portion 522 may be permanently fixed or coupled to the standard base 520 when the head-mountable device 500 is manufactured. In other examples, the customized portion 522 may be removably attached to the standard base 520. Thus, the customizable portion 522 may be interchangeable, allowing the facial interface 504 to be changed depending on the individual user. This feature may allow a single head mountable device to accommodate multiple users.

[0087] In at least one example, the standard base 520 may include an isotropic grid structure that provides rigidity in each of the X, Y, and Z directions. Alternatively, the second portion (e.g., the customized portion 522) may have a first set of directional characteristics and a second set of directional characteristics that are different from the first set of directional characteristics. In other words, the customized portion 522 may include an anisotropic grid structure. The anisotropy of the grid structure of the customized portion 522 may be rigid (or substantially rigid) in the X direction and the Z direction. In addition, the anisotropy of the grid structure of the customized portion 522 may be compressible in the Y direction (compared to the standard base 520), thereby allowing the facial interface 504 to fit the user's face.

[0088] In at least one example, face joint 504 can be additively manufactured in a single process. Standard base 520 can be 3D printed using a first material having a first grid structure, while customized portion 522 can be 3D printed using a second material having a second grid structure. In other examples, standard base 520 can be 3D printed using a first material having a first grid structure, while customized portion 522 can be 3D printed using the same first material having a second grid structure different from the first grid structure. In other examples, standard base 520 can be 3D printed using a first material having a first grid structure, while customized portion 522 can be 3D printed using a second material different from the first material but having the same first grid structure.

[0089] although Figure 5The face joint 504 is shown as including two materials, but in other examples, the face joint may include additional materials, such as three, four, five, etc. These materials may repeat (e.g., the first layer may include the first material, the second layer may include the second material, the third layer may include the first material, etc.). Otherwise, the materials may be unique to each other. In addition, each layer of material may be manufactured to have various thicknesses. For example, the material layer that contacts the user's head 101 may be thicker than the material layer that contacts the buffer 406 to fit the user's head and face. Each layer (e.g., portion) may have any of the characteristics described above with respect to the first portion (standard base 520) or the second portion (custom portion 522).

[0090] Figure 5 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. Figure 5 Examples of devices, features, components and parts are shown. Figure 6 Additional details regarding the face joint having inserted materials and / or structures are described.

[0091] Figure 6 6 shows a top view of a head mountable device 600 having a face engaging portion 604 including an insert 624 according to one example. Although not all components are necessarily shown, the head mountable device 500 is respectively Figures 4 to 5 The head mountable device 600 may be the same or similar to the head mountable device 400 or 500, as indicated by similar reference numbers. For example, the head mountable device 600 may include the optical component 102, the display frame 105, and the buffer 406. The head mountable device 600 may include a face joint 604 having a grid structure, the grid structure including an insert 624 embedded in the grid structure. In at least one example, the insert 624 may include another material 615 that is different from the material 611 of the face joint 604. In some examples, the insert 624 may include a material inserted into (e.g., injection molded into, dripped into, pressed into, etc.) the material 611 during or after the additive manufacturing process.

[0092] In at least one example, the face interface 604 may include a material 611 that may be disposed around at least a portion of the insert 624. The material 611 may be characterized by a grid structure. The insert 624 may be a magnet, an attachment member, or a structural member. For example, the insert 624 may be a magnet that may be magnetically coupled to at least one of the display frame 105 or the buffer 406 to attach the face interface 604 to the head mountable device 600. Additionally or alternatively, the insert 624 may be an attachment member, such as a snap, hook and loop fastener, adhesive, or other suitable attachment mechanism, to attach the face interface 604 of the head mountable device 600. In some examples, the insert 624 may include both a magnet and an attachment member (e.g., the insert may be a magnetic snap, etc.). Both the magnet and / or attachment member configuration may allow the face interface 604 to be removable and interchangeable from the head mountable device 600.

[0093] In additional or alternative examples, the insert 624 can include a structural member. The structural member can be a material having a grid structure that provides structural rigidity to the face engaging portion 604. For example, the insert 624 can be a rigid metal or plastic component that is at least partially disposed within a portion of the insert 624. The insert 624 can be configured as a standard base for a face insert, such as described in reference to FIG. Figure 5 described.

[0094] In at least one example, the insert 624 can be additively manufactured with the face engaging portion 604. In this case, the insert 624 can be 3D printed in the same printing process as the face engaging portion 604. In at least one example, the 3D printed material 611 can be stretched over the insert 624. In this case, the insert 624 can be placed or additively manufactured before the face engaging portion 604 is placed. In other words, the face engaging portion 604 can be 3D printed in a process separate from the manufacturing and placement of the insert 624.

[0095] Figure 6 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. Figure 6 Examples of devices, features, components and parts are shown. Figures 7 to 9 Describes details related to the face joint with internal structure. Specifically, refer to Figure 7 Details of a face joint having a vertical beam structure are described.

[0096] Figure 77 shows a rear view of a head mountable device 700 having a face engaging portion 704 including a vertical beam 726 according to one example. Although not all components are necessarily shown, the head mountable device 700 and Figure 6 The head mountable device 700 may be the same or similar to the head mountable device 600, as indicated by similar reference numbers. For example, the head mountable device 700 may include an optical component 102, a display frame (not shown), and a buffer (not shown). The head mountable device 700 may include a face joint 704 having a grid structure, the grid structure including a vertical beam 726 embedded in the grid structure. In at least one example, the vertical beam may include another material 715 that is different from the material 711 of the face joint 704. In other examples, the vertical beam 726 is formed of the same material as other portions of the face joint 704.

[0097] In at least one example, the material 711 includes a first set of vertical beams 726 that are aligned relative to the contact surface 717 ( Figure 6 The contact surface 717 refers to the portion of the facial joint 704 that is compressed against and fits the user's face when the user wears the head mountable device 700.

[0098] The vertical beams 726 can provide anisotropic properties to the face joint 704. For example, the vertical beams 726 can allow the face joint 704 to be rigid in the X and Z directions while being conformable in the Y direction to accommodate the user's head size, shape, and facial contours.

[0099] The vertical beam 726 may be similar to Figure 6 inserts 724 as they may be 3D printed and / or placed within the facial joint 704.

[0100] Figure 7 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. Figure 7 Examples of devices, features, components and parts are shown. FIG. 8A to FIG. 8B Details of a face joint having a first set of vertical beams and a second set of vertical beam structures are described.

[0101] FIG. 8A to FIG. 8B A rear view of a head mountable device 800 having a face engaging portion 804 including a first set of vertical beams 826 and a second set of vertical beams 828 in non-deformed and deformed configurations, respectively, according to one example is shown. Fig. 8A The face joint 804 is shown with no force applied to compress the first set of vertical beams 826 and the second set of vertical beams 828 . Figure 8B The face joint 804 is shown with a force applied to compress the first set of vertical beams 826 and the second set of vertical beams 828. Although not all components are necessarily shown, the head mounted device 800 may be configured to Figure 7 The head mountable device 800 may be the same or similar to the head mountable device 700, as indicated by similar reference numerals. For example, the head mountable device 800 may include an optical component 102, a display frame (not shown), and a buffer (not shown).

[0102] The head mountable device 800 may include a face joint 804 having a grid structure including a first group of vertical beams 826 and a second group of vertical beams 828 embedded in a grid structure 811. The second group of vertical beams 828 may be stacked relative to the first group of vertical beams 826. The first group of vertical beams 826 and the second group of vertical beams 828 may be configured to bend laterally. The first group of vertical beams 826 may terminate along a portion of the face joint 804. The second group of vertical beams 828 may terminate along approximately the same portion of the face joint 804. The first group of vertical beams 826 and the second group of vertical beams 828 may bend laterally at their mutual contact points. The lateral bending between the first group of vertical beams 826 and the second group of vertical beams 828 may provide an anisotropic structure to the grid structure 811 of the face joint 804.

[0103] In at least one example, the first set of vertical beams 826 and the second set of vertical beams can include materials 815 and 817, respectively. At least one of the materials 815 and 817 can be different from the material 711 of the face engaging portion 704. In various examples, the materials of the first set of vertical beams 826 and the second set of vertical beams can be the same or different. In various examples, the grid structures of the first set of vertical beams 826 and the second set of vertical beams 828 can be the same or different.

[0104] FIG. 8A to FIG. 8B 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. 8A to FIG. 8B Examples of devices, features, components and parts are shown. Fig. 9 Details of a face engaging portion having a C-shaped rib structure are described.

[0105] Fig. 9900 is shown with a rear view of a head mountable device 900 having a face engaging portion 904 including a C-shaped rib 926 according to one example. Although not all components are necessarily shown, the head mountable device 900 and FIG. 8A to FIG. 8B The head mountable device 800 is the same or similar, as indicated by similar reference numerals. For example, the head mountable device 900 may include an optical component 102, a display frame (not shown), and a buffer (not shown).

[0106] The C-shaped ribs 926 can provide anisotropic structure to the lattice structure 911 of the face engaging portion 904. For example, the C-shaped ribs 926 can provide compressibility in the Y direction while being relatively stiffer or more rigid in the X and Z directions. In at least one example, the material and / or 3D lattice structure of the C-shaped ribs 926 can be different than the material 711 of the face engaging portion 704.

[0107] Fig. 9 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. 9 Examples of devices, features, components and parts are shown. FIG. 10A to FIG. 10D and FIG. 11A to FIG. 11B Details of example grid structures are described.

[0108] Figures 10A to 10B as well as FIG. 11A to FIG. 11B Specific examples of lattice structures (e.g., 3D lattice structures) of face joints according to one or more examples of the present disclosure are shown. FIG. 10A to FIG. 10D and FIG. 11A to FIG. 11B As shown, the grid structure can have a geometry or pattern configuration of an auxetic structure, a honeycomb structure, a contiguous spherical structure, or a custom structure based on stress / strain mapping. Although not all components are necessarily shown, FIG. 10A to FIG. 10D and FIG. 11A to FIG. 11B The corresponding grid structures 1000a to 1000d and 1100, etc. can be used to form any of the above-mentioned face joints, inserts, vertical beams or C-shaped ribs.

[0109] Fig. 10AA grid structure 1000a having a geometric shape or pattern configuration of a honeycomb structure is shown. As used herein, a honeycomb structure is a grid structure comprising a hexagonal (e.g., triangular) grid having a two-point basis. In other words, the honeycomb grid structure comprises two different hexagonal grid structures offset from each other. The honeycomb structure, as well as other grid structures described below, can provide a facial joint with a lightweight design while allowing customized properties, such as rigidity and conformability in various directions. In addition, properties such as thermal properties and acoustic properties can be tuned by changing or tuning the grid structure. In some examples, the grid structure can allow airflow to reach the user's face while still providing desired rigidity and conformability properties.

[0110] Fig. 10B A lattice structure 1000b is shown having a geometric shape or pattern configuration of beam structures. The beam structures may form various polygonal patterns, such as triangles for desired material properties.

[0111] Fig. 10C A grating structure 1000c having a spiral grating structure geometry or pattern configuration is shown. The spiral grating structure may also be referred to as a triple periodic minimum surface (TPMS) or a Schwarz surface.

[0112] Fig. 10D A grid structure 1000d is shown having a random grid geometry or pattern configuration. A random grid may also be referred to as a Voronoi grid.

[0113] In other examples, the grid structure may have other geometric shapes or patterns, such as abutting spheres, triangular pyramids, quadrangular pyramids, cubes, etc. In addition, the grid may be periodic, aperiodic, or random. In some examples, the grid may be trimmed into a specific design (e.g., to wrap around the user's head) or may be compressed into a specific shape (e.g., to pass through the user's head). Various grid structures may be manufactured via additive manufacturing (e.g., 3D printing).

[0114] In some examples, various grid structures may also include customized structures based on stress-strain mapping. Stress-strain mapping may indicate mechanical characteristics and properties of the grid structure, particularly stress and strain in response to applied forces, vibrations, heat, fluid flow, or other physical effects. Examples of stress-strain mapping may include 3D numerical simulations, such as finite element analysis mapping. In these or other examples, stress and strain may affect parameters such as deflection, energy absorption (e.g., due to compression, vibration, impact, etc.), stiffness, etc.

[0115] In at least one example, the grid structure may include an elastomeric material. The elastomeric material may include a polymer having viscoelastic properties (e.g., both viscosity and elasticity) with a low Young's modulus. Elastomeric materials may be characterized by their ability to return to their original shape in the absence of a deforming force. Examples of elastomeric materials may include rubber, styrene-butadiene block copolymers, polyisoprene, polybutadiene, ethylene propylene rubber, ethylene propylene diene monomer rubber, silicone elastomers, fluoroelastomers, polyurethane elastomers, nitrile rubber, and the like.

[0116] FIG. 10A to FIG. 10D 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. Likewise, 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. 10A to FIG. 10D Examples of devices, features, components and parts are shown. FIG. 11A to FIG. 11B Describe the details of the auxetic grid structure.

[0117] FIG. 11A to FIG. 11B A lattice structure 1100 is shown that includes a geometric shape or pattern configuration of auxetic structures. Fig.11A The grid structure 1100 is shown in the absence of a deforming force. Fig. 11B The grid structure 1100 is shown under the influence of a deformation force F.

[0118] In at least one example, the lattice structure 311 may include a geometry or pattern configuration of an auxetic structure. As used herein, an auxetic structure refers to a lattice structure that, when stretched (e.g., when a force is applied to extend the lattice structure along a first direction), becomes thicker in a second direction perpendicular to the applied force. More specifically, the auxetic structure has a negative Poisson's ratio (a measure of the deformation (expansion or contraction) of a material in a direction perpendicular to the direction of the load). For example, Fig. 11B As depicted, when stretched by a deforming force F, the lattice structure 1100 expands (eg, becomes thicker, as indicated by the vertical arrow) in a direction perpendicular to the deforming force F. In contrast, a non-auxetic structure becomes thinner in a direction perpendicular to the direction of the deforming force.

[0119] In some examples, the auxetic grid structure can have mechanical properties, such as fracture resistance in one or more directions within the grid. Thus, the auxetic grid structure 311 can provide rigidity to the face joint 304 in one or more directions while being compressible and conformable in other directions. In one example, the face joint 304 can be rigid along the top to bottom direction and the side to side direction of the head 101 to prevent the face joint 304 from sagging when the head mountable device is worn by the user. Additionally or alternatively, the face joint 304 can be compressible and conformable along the front-to-back direction of the head 101, thereby allowing the face joint 304 to adapt to the specific head shape and facial contours of the user. In at least some examples, the auxetic structure can provide mechanical properties, such as high energy absorption, fracture resistance, impact absorption, etc.

[0120] FIG. 11A to FIG. 11B 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. Likewise, any of the features, components, and / or parts shown and 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. 11A to FIG. 11B Examples of devices, features, components, and parts are shown.

[0121] To the extent applicable to the present technology, the collection and use of data obtained from various sources may be used to improve the delivery of inspirational content or any other content that may be of interest to the user. The present disclosure contemplates that in some examples, the collected data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data may include demographic data, location-based data, phone numbers, email addresses, ID, home address, data or records related to the user's health or fitness level (e.g., vital sign measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

[0122] The present disclosure recognizes that the use of such personal information data in the present technology can be used to benefit users. For example, the personal information data can be used to deliver targeted content that users are more interested in. Therefore, the use of such personal information data enables users to have planned control over the content delivered. In addition, the present disclosure also anticipates other uses of personal information data that benefit users. For example, health and fitness data can be used to provide insights into the user's overall health status, or can be used as positive feedback to individuals who use technology to pursue health goals.

[0123] The disclosure anticipates that entities responsible for the collection, analysis, disclosure, transmission, storage or other purposes of such personal information data will comply with sound privacy policies and / or privacy measures. Specifically, such entities should implement and adhere to the use of privacy policies and practices that are recognized as meeting or exceeding the industry or government requirements for maintaining the privacy and security of personal information data. Such policies should be easy for users to access and should be updated as changes in the collection and / or use of data occur. Personal information from users should be collected for legal and reasonable entity purposes and should not be shared or sold outside these legal purposes. In addition, such collection / sharing should be carried out after receiving the informed consent of the user. In addition, such entities should consider taking any necessary steps to protect and safeguard access to such personal information data, and ensure that other entities with access to personal information data comply with their privacy policies and procedures. In addition, such entities can subject themselves to third-party assessments to prove that they comply with widely accepted privacy policies and practices. In addition, policies and practices should be adapted to specific types of personal information data collected and / or accessed, and to applicable laws and standards including considerations of special jurisdictions. For example, in the United States, the collection or acquisition of certain health data may be governed by federal and / or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); while health data in other countries may be subject to other regulations and policies and should be handled accordingly. Therefore, different privacy measures should be advocated for different types of personal data in each country.

[0124] Regardless of the foregoing, the present disclosure also contemplates implementation schemes in which users selectively block the use or access of personal information data. That is, the present disclosure contemplates hardware elements and / or software elements to prevent or block access to such personal information data. For example, with respect to an advertising delivery service, the technology of the present invention may be configured to allow a user to choose to "opt in" or "opt out" to participate in the collection of personal information data at any time during or after registration for the service. In another example, a user may choose not to provide emotion-related data for a target content delivery service. In another example, a user may choose to limit the length of time that emotion-related data is retained, or completely prohibit the development of basic emotional conditions. In addition to providing "opt-in" and "opt-out" options, the present disclosure also contemplates providing notifications related to access or use of personal information. For example, a user may be notified that the user's personal information data will be accessed when downloading an application, and then the user may be reminded again just before the personal information data is accessed by the application.

[0125] In addition, it is the intention of the present disclosure that personal information data should be managed and processed in a manner that minimizes the risk of unintentional or unauthorized access or use. Once the data is no longer needed, the risk can be minimized by limiting data collection and data deletion. In addition, and when applicable, including in certain health-related applications, data de-identification can be used to protect the privacy of users. De-identification can be facilitated by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of stored data (e.g., collecting location data at the city level rather than at the address level), controlling how the data is stored (e.g., aggregating data between users), and / or other methods when appropriate.

[0126] Thus, while the present disclosure broadly covers the use of personal information data to implement one or more of the various disclosed embodiments, the present disclosure also contemplates that various embodiments may also be implemented without access to such personal information data. That is, various embodiments of the present technology will not fail to function properly due to the lack of all or a portion of such personal information data. For example, content may be selected and delivered to a user by inferring preferences based on non-personal information data or an absolute minimum amount of personal information, such as content requested by a device associated with the user, other non-personal information available to a content delivery service, or publicly available information.

[0127] For the purpose of illustration, the foregoing description uses specific nomenclature to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that specific details are not required in order to practice the embodiments. Therefore, for the purpose of illustration and description, the foregoing description of the specific embodiments described herein is presented. They are not intended to be exhaustive or to limit the embodiments to the precise form disclosed. It will be apparent to those of ordinary skill in the art that, in view of the above teachings, many modifications and variations are feasible.
