Description

Technical Field

[0001] This technology generally relates to head-mounted displays, positioning and stabilization structures, user interface connection structures, and other components used in head-mounted displays, including display units and associated head-mounted display components and systems with positioning and stabilization structures, interface connection structures and / or components, as well as methods. This technology is particularly applicable to the use of immersive reality head-mounted displays, and is described herein in this context. It should be understood that this technology can have broader applications and can be used in any type of head-mounted display device, including but not limited to virtual reality displays, augmented reality displays, and / or mixed reality displays. Background Technology

[0002] It should be understood that if any prior art is mentioned in this document, such reference does not constitute an acknowledgment that the prior art is common knowledge in the field in Australia or any other country.

[0003] Immersive technology

[0004] Immersive technology refers to technologies that attempt to recreate or enhance the physical environment by creating surrounding sensory experiences through digital or virtual environments, thereby generating a sense of immersion.

[0005] Specifically, immersive technology provides users with visual immersion and creates virtual objects and / or virtual environments. Immersive technology can also provide immersion for at least one of the other five senses.

[0006] Virtual Reality

[0007] Virtual reality (VR) is a computer-generated three-dimensional image or environment presented to a user. In other words, the environment may be entirely virtual. Specifically, the user observes an electronic screen to view virtual or computer-generated images within the virtual environment. Because the created environment is entirely virtual, the user may be prevented and / or hindered from interacting with their physical environment (e.g., they may not be able to hear and / or see physical objects in their current physical environment).

[0008] Electronic screens can be supported within the user's line of sight (e.g., mounted on the user's head). When viewing the screen, the visual feedback output by the screen and observed by the user can create a virtual environment designed to simulate the real environment. For example, a user can look around (e.g., 360°) by rotating their head or their entire body and interact with virtual objects observable by the user through the screen. This can provide an immersive experience where the virtual environment stimulates at least one of the user's five senses and replaces the corresponding stimuli of the physical environment when the user uses the VR device. Typically, this stimulation is at least related to the user's vision (i.e., because they are looking at the screen), but it can also include other senses. Electronic screens are typically mounted on the user's head so that they can be positioned close to the user's eyes, allowing the user to easily observe the virtual environment.

[0009] In addition to visual feedback, VR devices can also generate other forms of feedback. For example, VR devices may include speakers and / or be connected to speakers to provide auditory feedback. VR devices may also include haptic feedback (e.g., in the form of haptic responses), which can correspond to visual and / or auditory feedback. This can create a more immersive virtual environment because the user receives stimuli that correspond to more than one of the user's senses.

[0010] When using VR devices, users may wish to limit or block ambient stimuli. For example, users may want to avoid seeing and / or hearing their surroundings in order to better process stimuli from the VR device within the virtual environment. Therefore, VR devices can limit and / or prevent the user's eyes from receiving ambient light. In some instances, this can be achieved by providing a seal against the user's face. In some instances, the shield may be positioned close to (e.g., in contact with or in close contact with) the user's face, but may not seal against the user's face. In either instance, ambient light may not reach the user's eyes, making the only light the user can observe come from the electronic screen.

[0011] In other instances, VR devices can limit and / or prevent users from hearing ambient noise. In some instances, this can be achieved by providing the user with headphones (e.g., noise-canceling headphones) that can output sound from the VR device and / or limit the noise the user hears from their physical environment. In some instances, VR devices can output sound at a volume sufficient to limit the ambient noise the user can hear.

[0012] In any instance, a user may not want to be overstimulated (e.g., simultaneously stimulated by both their physical and virtual environments). Therefore, blocking and / or limiting environmental stimuli can help users focus on the virtual environment without being distracted by potential disturbances from their surroundings.

[0013] The following describes different types of VR devices. Typically, a single VR device can include at least two different categories. For example, VR devices can be categorized based on their portability and how the display unit connects to the rest of the interface. These categories can be independent, such that categorizing into one group (e.g., unit portability) does not predetermine categorization into another. Additional categories may also be available for classifying VR devices; these additional categories are not explicitly listed below.

[0014] Portability

[0015] Fixed unit

[0016] In some forms, VR devices can be used in conjunction with standalone devices such as computers or video game consoles. This type of VR device can be stationary because it cannot be used without a computer or video game console, thus limiting its usability (e.g., restricted by the location of the computer or video game console).

[0017] Portable unit

[0018] In some forms, VR devices can be standalone units, including a power supply and sensors, eliminating the need for connection to a computer or video game console. This provides users with greater freedom of use and mobility. For example, users are not limited to using VR devices near a computer or video game console, but can use them outdoors or in other environments that do not include a computer or television.

[0019] Because VR devices are not connected to a computer or video game console during use, they need to support all necessary electronic components. This includes batteries, sensors, and processors. These components add to the weight of the VR device, which the user must support against their body. Appropriate weight distribution may be necessary so that this added weight does not increase discomfort for the user wearing the VR device.

[0020] In some forms, the electrical components of a VR device are housed in a single shell that sits directly in front of the user's face during use. This configuration can be referred to as a "brick." In this configuration, the center of gravity of the VR device, without any positioning or stabilizing structures, is located directly in front of the user's face. To counteract the torque generated by gravity, the positioning and stabilizing structures attached to the brick configuration must provide forces directed towards the user's face, such as those generated by tension in the headband straps. While brick configurations may be advantageous in manufacturing (e.g., because all electrical components are close together) and allow for interchangeability of positioning and stabilizing structures (e.g., because they do not include electrical connections), the forces required to maintain the VR device's position (e.g., the tensile force in the headband) can be uncomfortable for the user. Specifically, the VR device may be inserted deep into the user's face, creating irritation and marks on the user's skin. The combination of these forces can feel like a "clamp," as the user's head receives forces from the display shell on their face and from the headband on the back of their head. This can make users less willing to wear the VR device.

[0021] Because VR devices and other mixed reality devices can be used in a manner involving vigorous movement of the user's head and / or entire body (e.g., during gameplay), there may be significant forces / torques that tend to disrupt the device's position on the user's head. Simply pressing the device closer to the user's head to withstand large, destructive forces may be unacceptable, as it could cause discomfort to the user, or become uncomfortable only after a short period of time.

[0022] In some forms, electrical components can be spaced out throughout the VR device, rather than being entirely in front of the user's face. For example, some electrical components (e.g., batteries) can be located on the positioning and stabilizing structure, particularly on the rear contact portion. In this way, the weight of the battery (or other electrical components) may generate a torque in the opposite direction to the torque generated by the rest of the VR device (e.g., the display). Therefore, applying a lower clamping force to the positioning and stabilizing structure may be sufficient, resulting in a lower force against the user's face (e.g., fewer marks on their skin). However, due to the electrical connections, cleaning and / or replacing the positioning and stabilizing structure can be more difficult in some of these existing devices.

[0023] In some forms, separating electrical components may involve positioning some of these components separately from the rest of the VR device. For example, the battery and / or processor may be electrically connected but carried separately from the rest of the VR device. Unlike in the “fixed unit” configuration described above, this battery and / or processor, along with the rest of the VR device, can be portable. For example, the battery and / or processor can be carried on the user's belt or in the user's pocket. This can provide the benefit of reducing weight on the user's head but does not provide counteracting torque. The tensile force provided by the positioning and stabilizing structure may still be less than in a “brick” configuration because the total weight of the head support is smaller.

[0024] Monitor connection

[0025] Integrated display screen

[0026] In some forms, the display screen is an integral part of the VR device and typically cannot be detached or removed from the rest of the VR device.

[0027] The display screen can be secured within the housing and protected from damage. For example, the display screen can be completely covered by the housing, which reduces the likelihood of scratches. Additionally, integrating the display screen with the rest of the VR device can prevent the display screen from being lost.

[0028] In these forms, the display screen serves purely as a display for immersive technology. The vast majority of "fixed units" will include an integrated display screen. "Portable units" may include an integrated display screen, or may include a removable display screen (described below).

[0029] Removable display screen

[0030] In some forms, the display screen is a separate structure that can be removed from the VR device and used independently.

[0031] In some forms, a portable electronic device (e.g., a mobile phone) can be selectively inserted into the housing of a VR device. This portable electronic device may include most or all of its sensors and / or processors and can create virtual environments via downloadable applications.

[0032] Portable electronic devices are typically lightweight and may not require positioning and stabilizing structures to exert significant force on the user's head.

[0033] Augmented Reality

[0034] In some forms, augmented reality (AR) is a computer-generated three-dimensional image or environment presented to the user.

[0035] While similar to VR, AR differs in that the virtual environment, created at least in part by an electronic screen, is observed in conjunction with the user's physical environment. In other words, AR creates virtual objects to alter and / or enhance the user's physical environment using elements of the virtual environment. The result of AR is a combined environment that includes both physical and virtual objects, and is therefore a hybrid of physical and virtual environments.

[0036] For example, images created by an electronic screen can be overlaid onto a user's physical environment. Only a portion of the combined AR environment presented to the user is virtual. Therefore, users may want to continue receiving environmental stimuli from their physical environment while using the AR device (e.g., to continue observing physical or non-virtual components of the combined environment).

[0037] Because AR can be used in conjunction with the user's physical environment, AR devices can be attached to a computer or video game console without being electrically connected or otherwise tethered. Instead, AR devices may include batteries or other power sources. This provides users with maximum freedom of movement, allowing them to explore various physical environments while using AR devices.

[0038] This key difference between VR and AR can lead to different types of wearable electronic screens. As mentioned above, users of VR devices may want to block ambient light, so the casing of the electronic screen may be opaque to limit or prevent ambient light from reaching the user. However, users of AR devices may want to see the virtual environment blend with their real-world environment. The electronic screen in an AR device can be similarly supported in front of the user's eyes, but the screen in an AR device can be transparent or semi-transparent, and these screens may not be supported by an opaque casing (or the opaque material may not substantially obstruct the user's view). This allows the user to continue receiving ambient stimuli while the virtual environment is simultaneously present. Nevertheless, some VR devices that do not have a transparent screen (through which the user can see their real-world environment) can be configured to achieve AR by taking real-time video of the user's real-world environment from the user's perspective (e.g., using a camera on the display casing) and displaying it on the display screen.

[0039] Additionally, users of AR devices may be more mobile than those using VR devices (e.g., because AR users can see their physical environment and / or are not bound by a computer or video game console). Therefore, users of AR devices may want to wear them for extended periods while moving around (e.g., walking, running, cycling, etc.). Including components such as batteries in AR devices may cause discomfort to the user's head and / or neck, and may prevent users from wearing the AR device for extended periods.

[0040] Mixed Reality

[0041] Mixed Reality (MR) is similar to AR, but potentially more immersive because MR devices can offer users more ways to interact with virtual objects or configured environments than AR devices. Virtual reality in MR can also overlap and / or blend with the user's physical environment. However, unlike AR, users may be able to interact with the virtual environment, similar to what happens in VR. In other words, while AR can present only computer-generated images of the physical environment, MR can present the same or similar computer-generated images to the user, but allow interaction with the images in the physical environment (e.g., using a hand to "grab" a virtually generated object). Therefore, the virtual environment can be further merged with the physical environment, resulting in a merged environment that better reflects the real-world environment.

[0042] Head-mounted display interface

[0043] Head-mounted display interfaces enable users to have an immersive experience of virtual environments and have a wide range of applications in fields such as communications, training, medical and surgical practices, engineering, and video games.

[0044] Different head-mounted displays can offer varying degrees of immersion. For example, some head-mounted displays can provide a fully immersive experience. One example of a fully immersive experience is virtual reality (VR). Head-mounted displays can also provide a partial level of immersion similar to that of AR devices.

[0045] VR head-mounted display interfaces are typically provided as systems including display units arranged in an operating position in front of a user's face. The display unit typically includes a housing containing a display and user interface structure configured and arranged relative to the user's face. The user interface structure may extend around the display and, together with the housing, define a viewing opening for the display. A user interface connection structure may engage with the face and includes padding for user comfort and / or light-tightness to block ambient light from the display. The head-mounted display system also includes a positioning and stabilization structure positioned on the user's head to maintain the display unit in proper position.

[0046] Other head-mounted display interfaces can provide a partially immersive experience. In other words, users can experience elements of their physical environment as well as elements of the virtual environment. Examples of partially immersive experiences are augmented reality (AR) and mixed reality (MR).

[0047] AR and / or MR head-mounted display interfaces are typically also provided as systems including display units arranged to be held in an operating position in front of the user's face. Similarly, the display unit typically includes a housing containing the display and user interface structure, which is constructed and arranged relative to the user's face. AR and / or MR head-mounted display systems are also similar to VR systems in that they include positioning and stabilization structures placed on the user's head to maintain the display unit in proper position. However, AR and / or MR head-mounted displays do not include padding that completely isolates the display from ambient light, as these less immersive experiences require elements of the physical environment. Instead, augmented and / or hybrid head-mounted displays allow users to see a combination of physical and virtual environments.

[0048] In any type of immersive technology, head-mounted display interface comfort is important to allow users to wear the display for extended periods. Additionally, it is important that the display can provide constantly changing images as the user's head position and / or orientation changes, in order to create an environment similar to or reproducing a fully physical environment, whether partially or fully virtual.

[0049] Interface connection structure

[0050] Head-mounted displays may include user interface connection structures. Since the interface connection parts come into direct contact with the user's face, their shape and configuration can directly affect the display unit's performance and comfort.

[0051] Designing the user interface connection structure presents many challenges. The face has a complex three-dimensional shape. The size and shape of the nose and head vary greatly between individuals. Because the head comprises bones, cartilage, and soft tissue, different areas of the face respond differently to mechanical forces.

[0052] One type of interface connection structure extends around the periphery of a display unit and is designed to seal against the user's face when force is applied to the user interface, wherein the interface connection structure engages opposite to the user's face. The interface connection structure may include a pad made of polyurethane (PU). With this type of interface connection structure, a gap may exist between the interface connection structure and the face, and therefore additional force may be required to force the display unit against the face to achieve the desired contact.

[0053] Areas where the user interface doesn't engage at all can create gaps between the facial interface and the user's face, through which unwanted light pollution can enter the display unit (e.g., especially when using virtual reality). Light pollution, or "light leakage," can reduce the user's sense of immersion and enjoyment. Additionally, previous systems may have been difficult to adjust to accommodate a wide range of head sizes. Furthermore, the display unit and associated stabilization structure are typically relatively heavy and may be difficult to clean, potentially further limiting the system's comfort and usability.

[0054] Another type of interface connection structure includes a sheet-like seal of thin material positioned around a portion of the periphery of the display unit to provide a seal against the user's face. Similar to the previous type of interface connection structure, additional force may be required to achieve a seal if the fit between the face and the interface connection structure is poor; otherwise, light may leak into the display unit during use. Furthermore, if the shape of the interface connection structure does not match the user's shape, it may wrinkle or buckle during use, causing undesirable light penetration.

[0055] The user interface can be partially characterized based on the design intent of the interface connection structure in its engagement with the face during use. Some interface connection structures may be limited to engaging with areas of the user's face that protrude beyond the curvature arc of the facial engagement surface of the interface connection structure. These areas typically include the user's forehead and cheekbones. This may cause discomfort to the user at localized stress points. Other facial areas may not be engaged by the interface connection structure at all, or may only be engaged in a negligible manner, and therefore may not be sufficient to increase the translational distance of the clamping pressure. These areas typically include the sides of the user's face, or areas adjacent to and surrounding the user's nose. It is advantageous that the interface connection structure or related components be adaptable to form appropriate contact or other relationships, depending on the degree of mismatch between the shape of the user's face and the interface connection structure.

[0056] Positioning and stability

[0057] To keep the display unit in its correct operating position, head-mounted display systems also include positioning and stabilizing structures positioned on the user's head. These structures are responsible for providing forces to counteract the weight of the head-mounted display and / or interface connection structures. In the past, these structures were formed from expandable rigid structures, which were typically applied to the head under tension to hold the display unit in its operating position. Such systems tended to apply clamping pressure to the user's face, potentially causing discomfort at localized stress points. Furthermore, prior systems could be difficult to adjust in order to allow for wide applicability to various head sizes. Additionally, the display unit and associated stabilizing structures were often heavy and difficult to clean, further limiting the system's comfort and usability.

[0058] Some other head-mounted display systems may not be functionally suitable for this field. For example, positioning and stabilization structures designed for aesthetic and visual appeal may not have the structural capability to maintain appropriate pressure around the face. For instance, excessive clamping pressure may cause user discomfort, or alternatively, insufficient clamping pressure on the user's face may not effectively seal the display from ambient light.

[0059] Some other head-mounted display systems may be uncomfortable or impractical for this technology. For example, prolonged use of the system.

[0060] Due to these challenges, some head-mounted displays suffer from one or more of the following problems: obtrusive, unattractive, expensive, poor fit, difficult to use, and uncomfortable, especially when worn for extended periods or when the user is unfamiliar with the system. Incorrectly sized positioning and stabilizing structures can reduce comfort and consequently shorten usage time.

[0061] Therefore, the interface connection portion of the user interface used for a fully immersive experience in a virtual environment is subjected to forces corresponding to the user's movement during the experience.

[0062] Material

[0063] The materials used in head-mounted display components include dense foam for parts of the contact interface connection structure, a rigid shell for the housing, and positioning and stabilizing structures formed by rigid plastic clamping structures. These materials have various drawbacks, including: they do not allow the skin covered by the material to breathe, they are not flexible, they are difficult to clean, and they are prone to bacterial growth. Therefore, products made with these materials may be uncomfortable to wear for extended periods, causing skin irritation in some individuals and limiting the application of these products. Utility Model Content

[0064] This technology may relate to providing positioning and stabilization structures for supporting, stabilizing, mounting, utilizing and / or fixing head-mounted displays, which have one or more of the following: improved comfort, cost, efficiency, ease of use and manufacturability.

[0065] The first aspect of this technology relates to a device for supporting, stabilizing, mounting, utilizing, and / or fixing a head-mounted display.

[0067] On the other hand, there is a positioning and stabilization structure for a head-mounted display, which includes a rear (or rear) support structure (or portion) arranged to contact the user's head in use.

[0068] In some forms, the rear support portion or at least a portion thereof is positioned behind the user's ear base.

[0070] In some forms, the positioning and stabilization structure also includes opposing connectors positioned on opposite sides of the user's head and extending along the temporal region of the user's head to interconnect the rear support portion to the head-mounted display unit. In some forms, the positioning and stabilization structure includes connecting the rear support portion to the front support portion of the head-mounted display unit.

[0153] Before describing the present technology in further detail, it should be understood that the present technology is not limited to the specific instances described herein, and the specific instances described herein may vary. It should also be understood that the terminology used in this invention is for the purpose of describing the specific instances discussed herein and is not intended to be limiting.

[0154] The following description is provided for various instances that may share one or more common characteristics and / or features. It should be understood that one or more features of any instance may be combined with one or more features of another instance or other instances. Furthermore, any single feature or combination of features of any instance may constitute another instance.

[0155] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description. The illustrative embodiments described in the detailed description, depicted in the drawings, and defined in the claims are not intended to be limiting. Other embodiments may be utilized and other changes may be made without departing from the spirit or scope of the subject matter presented. It will be readily understood that the aspects of this disclosure, as generally described herein and illustrated in the drawings, can be arranged, substituted, combined, separated, and designed in a variety of different configurations, all of which are contemplated in this disclosure.

[0156] Immersive technology

[0157] Immersive technology can present users with a combination of virtual and physical environments or the real world. Users can then interact with the resulting immersive or composite reality.

[0158] This device immerses the user by using virtual stimuli to enhance or replace stimuli associated with one of the user's five senses. Typically, this is a virtual stimulus, although additional stimuli may be present that enhance or replace the stimulus associated with one of the other four senses.

[0159] In some forms, specific immersive technologies can present a combination of a virtual environment and the user's physical environment. At least a portion of the resulting environment may include a virtual environment. In some instances, the entire resulting environment may be a virtual environment (e.g., meaning the user's environment may be obstructed or otherwise hindered). In other forms, at least a portion of the user's physical environment remains visually observable.

[0160] In some forms, users can use different types of immersive technologies, which may include, but are not limited to, virtual reality (VR), augmented reality (AR), or mixed reality (MR). Each type of immersive technology can present users with different environments and / or different ways of interacting with those environments.

[0161] In some forms, the display system can be used with every type of immersive technology. The display screen of the display system can provide virtual environment components to the combined environment (i.e., a combination of a virtual environment and the user's environment). In some forms, the display screen can be an electronic screen.

[0162] In at least some types of immersive technologies (e.g., VR, AR, MR, etc.), positioning and stabilizing the electronic screen can aid in operating the corresponding device. For example, a user might want the electronic screen positioned close enough to their eyes for easy viewing, yet far enough away to avoid discomfort. Additionally, the screens may need to be spaced far enough so that the user can wear corrective lenses, such as glasses, simultaneously. Furthermore, the user can manage to maintain the orientation of the electronic screen relative to their eyes. In other words, users walking or otherwise moving while using these devices may not want the device to wobble or otherwise move over their head (e.g., particularly relative to their eyes), as this could cause dizziness and / or discomfort. Therefore, these devices can be supported close to the user's head to limit relative movement between the user's eyes and the device.

[0163] In one form, the technology includes a method for using a VR device, the method comprising supporting the device on the user's head, close to at least one of the user's eyes, and within the user's line of sight.

[0164] In some instances of this technology, the head-mounted display unit is supported in front of the user's eyes in order to block, impede, and / or limit ambient light from reaching the user's eyes.

[0165] Unless the context explicitly requires otherwise, any features disclosed below in the context of a device configured for VR will be understood to apply to a device configured for AR. Similarly, unless the context explicitly requires otherwise, any features disclosed below in the context of a device configured for AR will be understood to apply to a device configured for VR. To avoid ambiguity, unless the context explicitly requires otherwise, features disclosed in the context of a device without a transparent display (through which the user can view the real world) will be understood to apply to a device with such a transparent display. Similarly, features disclosed in the context of a device with a transparent display (through which the real world can be viewed) will be understood to apply to a device where the display is electronic and the real world cannot be viewed directly through a transparent material.

[0166] Virtual Reality Display System

[0167] like Figure 4A and Figure 4B As shown, a display device, display system, display interface, or head-mounted display system 1000 according to one aspect of the present technology includes the following functional aspects: an interface connection structure 1100, a head-mounted display unit 1200, and a positioning and stabilization structure 1300. In some forms, the functional aspects may provide one or more physical components. In some forms, one or more physical components may provide one or more functional aspects. The head-mounted display unit 1200 may include a display screen. In use, the head-mounted display unit 1200 is arranged to be positioned near and in front of the user's eyes so as to allow the user to view the display screen.

[0168] In other aspects, the head-mounted display system 1000 may also include a display unit housing 1205, an optical lens 1240, a controller 1270, a speaker 1272, a power supply 1274, and / or a control system 1276. In some instances, these may be integral parts of the head-mounted display system 1000, while in other instances, these may be modular and integrated into the head-mounted display system 1000 according to user needs.

[0169] Head-mounted display unit

[0170] The head-mounted display unit 1200 may include structures for providing observable output to a user. Specifically, the head-mounted display unit 1200 is arranged to be held (e.g., manually, by positioning and stabilizing structures, etc.) in an operating position in front of the user's face.

[0171] In some instances, the head-mounted display unit 1200 may include a display screen 1220, a display unit housing 1205, an interface connection structure 1100, and / or an optical lens 1240. These components may be permanently assembled in a single head-mounted display unit 1200, or they may be detachable and selectively connected by the user to form the head-mounted display unit 1200. Additionally, the display screen 1220, display unit housing 1205, interface connection structure 1100, and / or optical lens 1240 may be included in the head-mounted display system 1000, but may not be part of the head-mounted display unit 1200.

[0172] Display screen

[0173] Some forms of the head-mounted display unit 1200 include displays, such as display screens (in... Figure 4B (Not shown, but disposed within the display unit housing 1205). The display screen may include electrical components that provide observable output to the user.

[0174] In one form of this technology, the display screen provides optical output that is observable by the user. This optical output allows the user to observe a virtual environment and / or virtual objects.

[0175] The display screen can be positioned close to the user's eyes to allow for viewing. For example, the display screen can be positioned in front of the user's eyes. The display screen can output computer-generated images and / or virtual environments.

[0176] Display housing

[0177] In such Figure 4A and Figure 4B In some forms of the present technology shown, the display unit housing 1205 provides a support structure for the display screen to maintain the position of at least some components of the display screen relative to each other and may additionally protect the display screen and / or other components of the head-mounted display unit 1200. The display unit housing 1205 may be made of a material suitable for protecting the display screen from impact forces. The display unit housing 1205 may also come into contact with the user's face and may be made of a biocompatible material suitable for limiting irritation to the user.

[0178] According to this technology, some forms of display unit housing 1205 may be made of rigid, stiff or semi-rigid materials (such as plastic).

[0179] In some forms, rigid or semi-rigid materials may be at least partially covered with soft and / or flexible materials (e.g., textiles, silicone, etc.). This can improve biocompatibility and / or user comfort because at least a portion of the display unit housing 1205 that the user engages with (e.g., grips with their hands) comprises soft and / or flexible materials.

[0180] Other forms of display unit housing 1205 according to this technology may be made of soft, flexible, elastic materials (such as silicone rubber).

[0181] Interface connection structure

[0182] like Figure 4A and Figure 4B As shown, some forms of this technology include an interface connection structure 1100 that is positioned and / or arranged to conform to the shape of a user's face and can provide the user with increased comfort when wearing and / or using the head-mounted display system 1000.

[0183] In some configurations, the interface connection structure 1100 is attached to the surface of the display unit housing 1205.

[0184] In some forms, the interface connection structure 1100 may extend at least partially around the display unit housing 1205 and may form a viewing opening. In use, this viewing opening may at least partially accommodate the user's face. Specifically, the user's eyes may be accommodated within the viewing opening formed by the interface connection structure 1100.

[0185] In some forms, the interface connection structure 1100 according to this technology may be made of biocompatible materials.

[0186] In some forms, the interface connection structure 1100 according to the present technology may be made of soft, flexible and / or elastic materials.

[0187] In some forms, the interface connection structure 1100 according to this technology may be made of silicone rubber and / or foam.

[0188] In some forms, the interface connection structure 1100 may contact sensitive areas of the user's face, which may be uncomfortable locations. The material forming the interface connection structure 1100 can cushion these sensitive areas and limit user discomfort when wearing the head-mounted display system 1000.

[0189] In some forms, these sensitive areas may include the user's forehead. Specifically, this could include areas of the user's head near the frontal bone, such as the cranial muscles and / or the space between the eyebrows. This area may be sensitive because the natural cushioning of muscle and / or fat between the user's skin and bone is limited. Similarly, the user's nasal ridge may also include little or no natural cushioning.

[0190] In some forms, the interface connection structure 1100 may include a single element. In some embodiments, the interface connection structure 1100 may be designed for mass production. For example, the interface connection structure 1100 may be designed to comfortably fit a wide range of different facial shapes and sizes.

[0191] In some forms, the interface connection structure 1100 may include different elements that cover different areas of the user's face. Different portions of the interface connection structure 1100 may be made of different materials and provide different textures and / or cushioning for the user in different areas.

[0192] Sunshade

[0193] Some forms of the head-mounted display system 1000 may include a light shield, which may be made of an opaque material and can block ambient light from reaching the user's eyes. The light shield may be part of the interface connection structure 1100 or may be a separate element. In some instances, in addition to providing a comfortable contact area between the head-mounted display 1200 and the user's face, the interface connection structure 1100 may also form a light shield by protecting the user's eyes from ambient light. In some instances, the light shield may be formed of multiple components that work together to block ambient light.

[0194] In some forms, a light shield can block ambient light from reaching the eye area. This light shield can be formed on the craniotomy muscle, on the user's sphenoid bone, across the sphenoid bone to the outer cheek area between the left and right zygomatic arches, above the zygomatic arch, across the inner cheek area from the zygomatic arch towards the pterygoid ridge, and on the nasal ridge below the user's nose bridge point, to surround a portion of the user's face.

[0195] In one form, the hood may not contact the user's face around its entire perimeter. For example, the hood may be spaced apart from the user's nasal ridge. The width of this gap may be substantially small in order to substantially limit the entry of ambient light. However, the user's nasal ridge may be sensitive and easily irritated. Therefore, avoiding direct contact with the user's nasal ridge when wearing the head-mounted display system 1000 can improve user comfort.

[0196] In some forms, the light shield may be part of the display unit housing 1205 and may be integrally or removably attached to the display unit housing 1205. In one form, if the display unit housing 1205 can be used with a display screen that outputs AR or MR and VR, the light shield may be removed from the display unit housing 1205 and attached to the display unit housing 1205 only when using VR.

[0197] Positioning and stabilizing structure

[0198] like Figure 4A and Figure 4B As shown, the display screen 1220 and / or display unit housing 1205 of the head-mounted display system 1000 of this technology can be held in place by the positioning and stabilizing structure 1300 during use.

[0199] To maintain the display screen 1220 and / or the display unit housing 1205 in their correct operating position, the positioning and stabilizing structure 1300 should ideally rest against the user's head comfortably, in a way that minimizes facial imprints and / or pain from prolonged use, to accommodate the load caused by the weight of the display unit. A universal fit is also required without sacrificing comfort, usability, and manufacturing costs. Design criteria may include adjustability within a predetermined range, and a low-touch, easy-to-set-up solution with a low dexterity threshold. Further considerations include catering to the dynamic environment in which the head-mounted display system 1000 can be used. As part of an immersive experience in a virtual environment, the user can communicate, i.e., speak, while using the head-mounted display system 1000. This allows the user's jaw or mandible to move relative to the other bones of the skull. Additionally, the entire head can move during the period of use of the head-mounted display system 1000. For example, movement of the user's upper body, and in some cases, movement of the lower body, and particularly movement of the head relative to both the upper and lower body.

[0200] In one configuration, the positioning and stabilizing structure 1300 provides holding forces to overcome the effects of gravity on the display screen 1220 and / or the display unit housing 1205.

[0201] In one form of this technology, a positioning and stabilizing structure 1300 is provided, configured in a manner consistent with comfortable wear by a user. In one example, the positioning and stabilizing structure 1300 has a low profile or cross-sectional thickness to reduce the perceived or actual volume of the device. In one example, the positioning and stabilizing structure 1300 includes at least one strip with a rectangular cross-section. In one example, the positioning and stabilizing structure 1300 includes at least one flat strip.

[0202] In one form of this technology, a positioning and stabilizing structure 1300 is provided, configured so as not to be too large and bulky, so as not to prevent the user from comfortably moving their head from one side to the other.

[0203] In one form of this technology, the positioning and stabilizing structure 1300 includes a strip comprised of a laminated structure consisting of a user-contact textile layer, a foam inner layer, and a textile outer layer. In one form, the foam is porous to allow moisture (e.g., sweat) to pass through the strip. In one form, the skin-contact layer of the strip is formed of a material that helps to absorb moisture from the user's face. In one form, the textile outer layer includes a loop material for engagement with a hook material portion.

[0204] In some forms of this technology, the positioning and stabilizing structure 1300 includes an extendable strip, such as an elastically extendable strip. For example, the strip may be configured to be taut in use and to guide force to pull the display screen 1220 and / or the display unit housing 1205 toward a portion of the user's face, particularly close to the user's eyes and in line with their field of vision. In one example, the strip may be configured as a tie.

[0205] In one form of the present technology, the positioning and stabilizing structure 1300 includes a first lacing strap that is configured and arranged such that, in use, at least a portion of its lower edge passes over the supraaural base of the user's head and covers a portion of the parietal bone without covering the occipital bone.

[0206] In one form of the present technology, the positioning and stabilizing structure 1300 includes a second tether that is configured and arranged such that, in use, at least a portion of its upper edge passes below the subauricular base of the user's head and covers or is located below the occipital bone of the user's head.

[0207] In one form of the present technology, the positioning and stabilizing structure 1300 includes a third lacing strap that is configured and arranged to interconnect the first and second lacing straps to reduce the tendency of the first and second lacing straps to move apart from each other.

[0208] In some forms of this technology, the positioning and stabilizing structure 1300 includes a flexible and, for example, non-rigid strip. An advantage of this is that the strip provides greater comfort against the user's head.

[0209] In some forms of this technology, the positioning and stabilizing structure 1300 includes strips configured to be breathable to allow wet vapor to pass through the strips.

[0210] In some forms of this technology, a system is provided comprising more than one positioning and stabilizing structure 1300, each configured to provide a holding force corresponding to a range of different sizes and / or shapes. For example, the system may include one form of positioning and stabilizing structure 1300 suitable for large-sized heads but not for small-sized heads, and another form of positioning and stabilizing structure suitable for small-sized heads but not for large-sized heads.

[0211] In some forms, the positioning and stabilizing structure 1300 may include a cushioning material (e.g., a foam pad) for contact with the user's skin. The cushioning material can provide additional abrasion resistance to the positioning and stabilizing structure 1300, especially if the positioning and stabilizing structure 1300 is made of a rigid or semi-rigid material.

[0212] Temporal connector

[0213] like Figure 4C As shown, some forms of the head-mounted display system 1000 or positioning and stabilization structure 1300 include a temporal connector 1250 or arm, each of which can cover a corresponding one in the user's temporal bone during use. A portion of the temporal connector 1250 contacts an area of ​​the user's head near the supraacus base (i.e., above each of the user's ears) during use. In some instances, the temporal connector is a strip portion of the positioning and stabilization structure 1300. In other instances, the temporal connector is an arm of the head-mounted display unit 1200. In some instances, the temporal connector of the head-mounted display system 1000 may be partially formed by a strip portion of the positioning and stabilization structure 1300 (e.g., an outer strip portion 1330) and partially formed by an arm 1210 of the head-mounted display unit 1200.

[0214] The temporal connector 1250 may be an outer portion of the positioning and stabilizing structure 1300, since each temporal connector 1250 is positioned on the left or right side of the user's head.

[0215] In some forms, the temporal connector 1250 may extend in the anteroposterior direction and may be substantially parallel to the sagittal plane.

[0216] In some configurations, the temporal connector 1250 may be coupled to the display unit housing 1205. For example, the temporal connector 1250 may be coupled to the outer side of the display unit housing 1205. For example, each temporal connector 1250 may be coupled to a corresponding one of the left outer side 1234 and the right outer side 1236.

[0217] In some forms, the temporal connector 1250 may be pivotally connected to the display unit housing 1205, and relative rotation may be provided between each temporal connector 1250 and the display unit housing 1205.

[0218] In some forms, the temporal connector 1250 can be removably connected to the display unit housing 1205 (e.g., via a magnet, mechanical fastener, hook and loop material, etc.).

[0219] In some forms, the temporal connector 1250 may be arranged in use to generally run along or parallel to the Frankfurt plane of the head and extend above the cheekbone (e.g., above the user's cheekbone).

[0220] In some forms, the temporal connector 1250 can be positioned against the user's head, similar to the temple of eyeglasses, and positioned higher than the antihelix of each ear.

[0221] In some forms, the temporal connector 1250 may have a generally elongated and flat configuration. In other words, the length and width (in the direction from top to bottom in the paper plane) of each temporal connector 1250 are much greater than its thickness (in the direction into the paper plane).

[0222] In some forms, the temporal connector 1250 may each have a three-dimensional shape with curvature along all three axes (X, Y, and Z). While the thickness of each temporal connector 1250 may be substantially uniform, its height varies throughout its length. The shape and size of each temporal connector 1250 are designed to fit snugly to the user's head so as to remain unobtrusive and maintain a low profile (e.g., not appearing too bulky).

[0223] In some forms, the temporal connector 1250 may be made of a rigid or semi-rigid material, which may include plastic, thermoplastic polyester elastomer, or another similar material. This rigid or semi-rigid material may be self-supporting and / or able to maintain its shape without wear. This allows the user to more intuitively or clearly understand how to use the positioning and stabilizing structure 1300, and contrasts with a completely loose positioning and stabilizing structure 1300 that does not maintain its shape. Maintaining the temporal connector 1250 in its in-use state before use prevents or limits deformation when the user wears the positioning and stabilizing structure 1300, and allows the user to quickly assemble or wear the head-mounted display system 1000.

[0224] In some forms, the temporal connector 1250 can be a reinforcement, which allows tension to be transmitted more effectively (e.g., directly) through the temporal connector 1250, since the reinforcement limits the extent of elongation or deformation of the arm during use.

[0225] In some forms, the temporal connector 1250 may be at least partially flexible in one direction and more rigid in another. The user can bend or flex the temporal connector more in one direction than in the other. For example, the temporal connector 1250 may be at least partially flexible along an axis substantially parallel to the user's sagittal plane (e.g., in the vertical direction during use). This allows the temporal connector 1250 to conform to the shape of the user's head by moving laterally toward or away from the user's head. The user can also make multiple adjustments along the length of the temporal connector 1250 to correspond to various structures along the user's head. However, bending along an axis substantially parallel to the user's coronal plane (e.g., extending laterally during use) may be more difficult. The temporal connector 1250 can resist bending in the vertical direction.

[0226] In some forms, the positioning and stabilizing structure 1300 can be designed so that it is "out of the box" and typically in its in-use configuration. Additionally, the positioning and stabilizing structure 1300 can be arranged to retain its in-use shape once unpacked (e.g., because reinforcements can be formed to maintain the shape of a portion of the positioning and stabilizing structure 1300). Advantageously, because the shape of the positioning and stabilizing structure 1300 is generally curved, closely resembling the rear portion of a user's head, the user can clearly understand the orientation of the positioning and stabilizing structure 1300. That is, the positioning and stabilizing structure 1300 is typically dome-shaped.

[0227] In some forms, flexible and / or elastic materials may be provided around the rigid or semi-rigid material of the temporal connector 1250. Flexible materials can provide a more comfortable fit against the user's head, thereby improving abrasion resistance and providing a soft contact with the user's face. In one form, the flexible material is a textile sleeve permanently or removably attached to each temporal connector 1250.

[0228] In one form, textile overlays can be molded onto at least one side of the reinforcement. In another form, the reinforcement can be formed separately from the elastic component, and then a socket formed of user contact material (e.g., Breath-O-Prene™) can be wrapped or slidably covered onto the reinforcement. In alternative forms, the user contact material can be provided to the reinforcement via adhesives, ultrasonic welding, stitching, hook and loop materials, and / or bolt connectors.

[0229] In some forms, the user contact material can be on both sides of the reinforcement, or alternatively, it can be on only the side of the reinforcement that contacts the user (e.g., the side that contacts the user) to reduce the volume and cost of the material.

[0230] In some forms, the temporal connector 1250 is made of a flexible material (e.g., textiles) that can comfortably fit against the user's skin and does not require additional layers to improve comfort.

[0231] Rear support section

[0232] like Figure 4C As shown, some forms of the positioning and stabilizing structure 1300 may include a rear support portion 1350 for helping to support the display screen 1220 and / or the display unit housing 1205 (in the context of the user's eyes). Figure 4B (As shown in the diagram). The rear support portion 1350 helps anchor the display screen and / or display unit housing 1205 to the user's head so that the display screen is properly oriented close to the user's eyes.

[0233] In some configurations, the rear support portion 1350 may be connected to the display unit housing 1205 via the temporal connector 1250.

[0234] In some configurations, the temporal connector 1250 can be directly connected to the display unit housing 1205 and the rear support portion 1350.

[0235] In some forms, the rear support portion 1350 may have a three-dimensional contour curve to conform to the shape of the user's head. For example, the three-dimensional shape of the rear support portion 1350 may have a generally circular three-dimensional shape, which is adapted to cover part of the parietal and occipital bones of the user's head during use.

[0236] In some forms, the rear support portion 1350 may include an upper segment 1310 and a lower segment 1320. The upper segment 1310 and the lower segment 1320 may be continuous and form a circular shape (e.g., circular, elliptical, etc.) for the rear support portion.

[0237] In some forms, the back support portion 1350 can be at least partially reinforced so that the circular shape is maintained even when the user is not wearing it. This helps the user put on the back support portion 1350 because the rigidity limits tangling.

[0238] In one form, stiffness can provide “elasticity” to the rear support portion 1350. For example, the rear support portion 1350 can “bounce” after being compressed. In other words, the rear support portion 1350 can be flexible enough to fold, but once the force is removed, the rear support portion 1350 returns to its original shape (e.g., a three-dimensional circular shape).

[0239] In some configurations, the rear support portion 1350 may be the rear portion of the positioning and stabilizing structure 1300. The rear support portion 1350 may provide at least partially forward-directing anchoring force.

[0240] In some forms, the lower segment 1320 of the posterior support portion 1350 is the lowermost part of the positioning and stabilizing structure 1300. For example, the posterior support portion 1350 may contact the area of ​​the user's head between the occipital bone and the trapezius muscle. The posterior support portion 1350 may hook onto the lower edge of the occipital bone (e.g., the occipital portion). The posterior support portion 1350 may provide an upward and / or forward force to maintain contact with the back of the user's head.

[0241] In some configurations, the lower section 1320 of the rear support portion 1350 is the lowest part of the entire head-mounted display system 1000. For example, the rear support portion 1350 may be positioned at the base of the user's neck (e.g., covering the occipital bone and trapezius muscle, which are lower than the user's eyes), such that the rear support portion 1350 is lower than the display screen 1220 and / or the display unit housing 1205.

[0242] In some configurations, the upper section 1310 can cover the parietal bone when in contact with the user's head. As described above, the circular shape of the rear support portion 1350 allows the rear support portion 1350 to lie substantially flat on the user's head, while the lower section 1320 contacts the user's head.

[0243] In some forms, the back support portion 1350 may include padding material that can contact the user's head (e.g., covering the area between the occipital bone and the trapezius muscle). The padding material can provide additional comfort to the user and limit the imprints caused by the back support portion 1350 pulling on the user's head.

[0244] In some configurations, the rear support portion 1350 may be made of textile and / or foam materials. These materials may be biocompatible and comfortable for the user's head.

[0245] In one embodiment, the rear support portion 1350 may be constructed of foam material at least partially covered by a fabric material. The outer fabric material provides a comfortable feel against the user's skin. The inner foam layer allows the rear support portion 1350 to compress and enhance comfort.

[0246] Forehead support

[0247] Some forms of the positioning and stabilizing structure 1300 may include a forehead support or forehead support portion 1360 configured to contact the user's head above the user's eyes during use. Figure 5BThe positioning and stabilizing structure 1300 shown includes a forehead support 1360. In some instances, Figure 4A The positioning and stabilizing structure 1300 shown may include a forehead support 1360. This forehead support 1360 may cover the frontal bone of the user's head. In some forms, the forehead support 1360 may also be positioned higher than the sphenoid bone and / or temporal bone. The forehead support 1360 may also be positioned higher than the user's eyebrows.

[0248] In some forms, the forehead support 1360 may be the front portion of the positioning and stabilizing structure 1300 and may be positioned more forward on the user's head than any other portion of the positioning and stabilizing structure 1300. The rear support portion 1350 may provide at least partially rearward-directed forces.

[0249] In some forms, the forehead support 1360 may include a cushioning material (e.g., textiles, foam, silicone, etc.) that comes into contact with the user and helps limit imprints caused by the strips of the positioning and stabilizing structure 1300. The forehead support 1360 and the interface connection structure 1100 can work together to provide comfort for the user.

[0250] In some forms, the forehead support 1360 may be separate from the display unit housing 1205 and may contact the user's head at a different location than the display unit housing 1205 (e.g., a higher location).

[0251] In some configurations, the forehead support 1360 can be adjusted to allow the positioning and stabilization structure 1300 to adapt to the shape and / or configuration of the user's face.

[0252] In some forms, the temporal connector 1250 may be coupled to the forehead support 1360 (e.g., on the lateral side of the forehead support 1360). The temporal connector 1250 may extend at least partially in a downward direction to be coupled to the posterior support portion 1350.

[0253] In some forms, the positioning and stabilizing structure 1300 may include multiple pairs of temporal connectors 1250. For example, one pair of temporal connectors 1250 may be coupled to the forehead support 1360, and another pair of temporal connectors 1250 may be coupled to the display unit housing 1205.

[0254] In some forms, the forehead support 1360 may be positioned at an angle generally parallel to the user's forehead to provide improved comfort. For example, the forehead support 1360 may be positioned to cover the frontal bone and be substantially parallel to the coronal plane. Positioning the forehead support substantially parallel to the coronal plane can reduce the likelihood of pressure sores caused by uneven presentation.

[0255] In some forms, the forehead support 1360 can be offset from a rear support or rear support portion that contacts the back of the user's head (e.g., the area covering the occipital bone and trapezius muscles). In other words, the axis along the rear strip does not intersect the forehead support 1360, and the forehead support 1360 can be positioned lower and further forward than the axis along the rear strip. The offset created between the forehead support 1360 and the rear strip can generate a torque against the weight of the display screen 1220 and / or the display unit housing 1205. A larger offset can generate a larger torque and thus better help maintain the correct position of the display screen 1220 and / or the display unit housing 1205. The offset can be increased by moving the forehead support 1360 closer to the user's eyes (e.g., further forward and lower along the user's head) and / or by increasing the angle of the rear strip to make it more vertical.

[0256] In some forms, the forehead support 1360 may be made of a compressible material that can provide support to the user during use.

[0257] In some forms, the forehead support 1360 may be made of silicone, foam, and / or textiles. For example, textiles may be used in combination with silicone or foam, although either of these materials may be used independently. When used together, the textile may be an outer layer of the forehead support 1360 and may come into contact with the user's head. The foam and / or silicone may be an inner layer that compresses when the forehead support 1360 is under tension on the user's head.

[0258] Adjustable strip

[0259] like Figure 4C As shown, the various parts of the positioning and stabilizing structure 1300 may be adjustable to apply selective tensile forces to the display screen 1220 and / or the display unit housing 1205 in order to fix the position of the display screen 1220 and / or the display unit housing 1205.

[0260] In some forms, the display unit housing 1205 may include at least one ring or eyelet 1254 (e.g. Figure 4B (As shown), and at least one of the temporal connectors 1250 can pass through the ring and fold back itself. The length of the temporal connector 1250 passing through the corresponding eyelet 1254 can be selected by the user to adjust the tensile force provided by the positioning and stabilizing structure 1300. For example, passing a longer temporal connector 1250 through the eyelet 1254 can provide a greater tensile force.

[0261] In some forms, at least one of the temporal connectors 1250 may include an adjustment portion 1256 and a receiving portion 1258 (e.g., Figure 4C (As shown). The adjustment portion 1256 can be positioned through an eyelet 1254 on the display unit housing 1205 and can be coupled to the receiving portion 1258 (e.g., by folding itself back). The adjustment portion 1256 may include a hook material, and the receiving portion 1258 may include a loop material (or vice versa), such that the adjustment portion 1256 can be removably held in the desired position. In some instances, the hook material and the loop material may be Velcro.

[0262] In some forms, adjusting the position of the adjustment portion 1256 relative to the receiving portion 1258 can apply a rearward force to the display screen 1220 and / or the display unit housing 1205, and increase or decrease the sealing force of the light shield on the user's head (e.g., when the light shield acts as a sealing forming structure).

[0263] In some forms, the adjustment portion 1256 may be made of a flexible and / or elastic material that can conform to the shape of the user's head and / or allow the adjustment portion to pass through the eyelet 1254. For example, the adjustment portion 1256 may be made of an elastic textile that can provide elastic tensile force. The remainder of the temporal connector 1250 may be made of the aforementioned rigid or semi-rigid materials (although additional sections of the temporal connector 1250 may also be made of flexible materials).

[0264] Top strip

[0265] In some forms, the positioning and stabilizing structure 1300 may include a top strip portion that can cover the upper area of ​​the user's head. For example, Figure 1A The head-mounted display system 1000 shown has a top strip section.

[0266] In some configurations, the top strip may extend between the front portion of the head-mounted display system 1000 and the rear portion of the head-mounted display system 1000.

[0267] In some forms, the top strip can be made of a flexible material and can be configured to complement the shape of the user's head.

[0268] In some configurations, the top strip portion may be connected to the display unit housing 1205. For example, the top strip portion may be connected to the upper surface 1230. The top strip portion may also be connected to the display unit housing 1205 near the rear end of the display unit housing 1205.

[0269] In some configurations, the top strip portion may be attached to the forehead support 1360. For example, the top strip portion may be attached to the forehead support 1360 near its upper edge. The top strip portion may be connected to the display unit housing 1205 via the forehead support 1360.

[0270] In some configurations, the top strip portion may be connected to the rear support portion 1350. For example, the top strip portion may be connected near the upper edge of the rear support portion 1350.

[0271] In some versions, the top strip can cover the frontal and parietal bones of the user's head.

[0272] In some forms, when the top strip portion extends between the front and rear portions of the head-mounted display system 1000, the top strip portion may extend along the sagittal plane.

[0273] In some forms, the top strip portion may be subjected to a tensile force oriented at least partially in the upward direction, which can counteract gravity.

[0274] In some forms, the top strip portion may be subjected to a tensile force that is at least partially oriented rearward, which may pull the interface connection structure 1100 toward the user's face (and provide a portion of the sealing force when the sunshade acts as a sealing forming structure).

[0275] In some forms, the top strip portion may be adjustable to apply selective tensile force to the display screen 1220 and / or display unit housing 1205 in order to fix the position of the display screen 1220 and / or display unit housing 1205.

[0276] In some forms, the display unit housing 1205 and / or forehead support 1360 (as applicable) may include at least one ring or eyelet 1254 through which a top strip portion may pass and fold back. The length of the top strip portion passing through the eyelet 1254 can be selected by the user to adjust the tensile force provided by the positioning and stabilizing structure 1300. For example, passing a longer length of the top strip portion through the eyelet 1254 may provide a greater tensile force.

[0277] In some forms, the top strip portion may include an adjustment portion and a receiving portion. The adjustment portion may be positioned through eyelet 1254 and may be attached to the receiving portion (e.g., by folding back on itself). The adjustment portion may include a hook material, and the receiving portion may include a loop material (or vice versa), such that the adjustment portion can be removably held in the desired position. In some instances, the hook material and loop material may be Velcro.

[0278] Augmented Reality Display Interface

[0279] like Figure 5A and Figure 5B As shown, a display device or head-mounted display system 1000 according to one aspect of the present technology includes the following functional aspects: a display screen 1220, a display unit housing 1205, and a positioning and stabilization structure 1300. In some forms, the functional aspects may provide one or more physical components. In some forms, one or more physical components may provide one or more functional aspects. In use, the display screen 1220 is arranged to be positioned near and in front of the user's eyes, thereby allowing the user to view the display screen 1220.

[0280] In other aspects, the head-mounted display system 1000 may also include an interface connection structure 1100, a controller 1270, a speaker 1272, a power supply 1274, and / or a control system 1276. In some instances, these may be integral parts of the head-mounted display system 1000, while in other instances, these may be modular and integrated into the head-mounted display system 1000 as needed by the user.

[0281] Display unit

[0282] The head-mounted display unit 1200 may include structures for providing observable output to a user. Specifically, the head-mounted display unit 1200 is arranged to be held (e.g., manually, by positioning and stabilizing structures, etc.) in an operating position in front of the user's face.

[0283] In some instances, the head-mounted display unit 1200 may include a display screen 1220, a display unit housing 1205, and / or an interface connection structure 1100. These components may be integrally formed in a single head-mounted display unit 1200, or they may be separable and selectively connected by the user to form the head-mounted display unit 1200. Additionally, the display screen 1220, the display unit housing 1205, and / or the interface connection structure 1100 may be included in the head-mounted display system 1000, but may not be part of the head-mounted display unit 1200.

[0284] Display screen

[0285] like Figure 5A As shown, some forms of the head-mounted display unit 1200 include a display screen 1220. The display screen 1220 may include electrical components that provide observable output to the user.

[0286] exist Figure 5A and Figure 5B In one embodiment of the present technology, the display screen 1220 provides optical output that is observable by the user. This optical output allows the user to observe a virtual environment and / or virtual objects.

[0287] The display screen 1220 can be positioned close to the user's eyes to allow the user to view the display screen 1220. For example, the display screen 1220 can be positioned in front of the user's eyes. The display screen 1220 can display computer-generated images that can be viewed by the user to enhance the user's physical environment (e.g., computer-generated images can appear as if they exist in the user's physical environment).

[0288] In some forms, particularly when using the display screen 1220 in an AR or MR environment, the display screen 1220 can be turned off while the user continues to wear it and interact with the physical environment. This allows the user to selectively choose when to receive virtual stimuli and when to only observe the physical environment.

[0289] In some forms, the display screen 1220 can be transparent (or semi-transparent). For example, the display screen 1220 can be glass, so the user can see through it. This can be particularly beneficial in AR or MR applications, allowing the user to continue seeing the physical environment.

[0290] Display housing

[0291] In such Figure 5A and Figure 5B In some forms of the present technology shown, the display unit housing 1205 provides a support structure for the display screen 1220 to maintain the position of at least some components of the display screen 1220 relative to each other, and may additionally protect the display screen 1220 and / or other components of the head-mounted display unit 1200. The display unit housing 1205 may be made of a material suitable for protecting the display screen 1220 from impact forces. The display unit housing 1205 may also contact the user's face and may be made of a biocompatible material suitable for limiting irritation to the user.

[0292] According to this technology, some forms of display unit housing 1205 may be made of rigid, stiff or semi-rigid materials (such as plastic).

[0293] In some forms, rigid or semi-rigid materials may be at least partially covered with soft and / or flexible materials (e.g., textiles, silicone, foam, etc.). This can improve biocompatibility and / or user comfort because at least a portion of the display unit housing 1205 that the user engages with (e.g., grips with their hands) comprises soft and / or flexible materials.

[0294] Other forms of display unit housing 1205 according to this technology may be made of soft, flexible, elastic materials (such as silicone rubber).

[0295] In some forms, the display screen 1220 may extend at least partially beyond the display unit housing 1205. For example, unlike the VR head-mounted display system 1000, the display screen 1220 in the AR (or MR) head-mounted display system 1000 may not be completely surrounded by the display unit housing 1205. The user can view the display screen 1220 directly and can view through the display screen 1220 (e.g., if the display screen 1220 is transparent or translucent).

[0296] In some forms, the display unit housing 1205 may support sensors or other electronic devices as described below. The display unit housing 1205 can provide protection for these electronic devices without substantially obstructing the user's view of the display screen 1220.

[0297] Interface Structure

[0298] like Figure 5A and Figure 5B As shown, some forms of this technology include an interface connection structure 1100 (also identified as "interface", "user interface", "interface structure", etc.) which is positioned and / or arranged to conform to the shape of a user's face and can provide additional comfort to the user when wearing and / or using the head-mounted display system 1000.

[0299] In some configurations, the interface connection structure 1100 is attached to the surface of the display unit housing 1205.

[0300] In some forms, the interface connection structure 1100 according to this technology may be made of biocompatible materials.

[0301] In some forms, the interface connection structure 1100 according to the present technology may be made of soft, flexible and / or elastic materials.

[0302] In some forms, the interface connection structure 1100 according to this technology may be made of silicone rubber and / or foam.

[0303] In some forms, the interface connection structure 1100 may contact sensitive areas of the user's face, which may be uncomfortable locations. The material forming the interface connection structure 1100 can cushion these sensitive areas and limit user discomfort when wearing the head-mounted display system 1000.

[0304] In some forms, these sensitive areas may include the user's forehead. Specifically, this could include areas of the user's head near the frontal bone, such as the cranial muscles and / or the space between the eyebrows. This area may be sensitive because the natural cushioning of muscle and / or fat between the user's skin and bone is limited. Similarly, the user's nasal ridge may also include little or no natural cushioning.

[0305] In some forms, the interface connection structure 1100 may include a single element. In some embodiments, the interface connection structure 1100 may be designed for mass production. For example, the interface connection structure 1100 may be designed to comfortably fit a wide range of different facial shapes and sizes.

[0306] In some forms, the interface connection structure 1100 may include different elements that cover different areas of the user's face. Different portions of the interface connection structure 1100 may be made of different materials and provide different textures and / or cushioning for the user in different areas.

[0307] In some forms, the interface structure 1100 may include nose pads (e.g., nose pads used in eyeglasses) that can contact the outside of the user's nose. The nose pads may apply slight pressure to the user's nose to maintain the position of the head-mounted display system 1000, but may not apply forces that would cause significant discomfort (e.g., the nose pads may not be subjected to a backward stretching force).

[0308] Positioning and stabilizing structure

[0309] like Figures 5A to 5B As shown, the display screen 1220 and / or display unit housing 1205 of the head-mounted display system 1000 of this technology can be held in place by the positioning and stabilizing structure 1300 during use.

[0310] To maintain the display screen 1220 and / or the display unit housing 1205 in their correct operating position, the positioning and stabilizing structure 1300 should ideally rest against the user's head comfortably, in a way that minimizes facial imprints and / or pain from prolonged use, to accommodate the load caused by the weight of the display unit. A universal fit is also required without sacrificing comfort, usability, and manufacturing costs. Design criteria may include adjustability within a predetermined range, and a low-touch, easy-to-set-up solution with a low dexterity threshold. Further considerations include catering to the dynamic environment in which the head-mounted display system 1000 can be used. As part of an immersive experience in a virtual environment, the user can communicate, i.e., speak, while using the head-mounted display system 1000. This allows the user's jaw or mandible to move relative to the other bones of the skull. Additionally, the entire head can move during the period of use of the head-mounted display system 1000. For example, movement of the user's upper body, and in some cases, movement of the lower body, and particularly movement of the head relative to both the upper and lower body.

[0311] In one configuration, the positioning and stabilizing structure 1300 provides holding forces to overcome the effects of gravity on the display screen 1220 and / or the display unit housing 1205.

[0312] In one form of this technology, a positioning and stabilizing structure 1300 is provided, configured in a manner consistent with comfortable wear by a user. In one example, the positioning and stabilizing structure 1300 has a low profile or cross-sectional thickness to reduce the perceived or actual volume of the device. In one example, the positioning and stabilizing structure 1300 includes at least one strip with a rectangular cross-section. In one example, the positioning and stabilizing structure 1300 includes at least one flat strip.

[0313] In one form of this technology, a positioning and stabilizing structure 1300 is provided, configured so as not to be too large and bulky, so as not to prevent the user from comfortably moving their head from one side to the other.

[0314] In one form of this technology, the positioning and stabilizing structure 1300 includes a strip comprised of a laminated structure consisting of a user-contact textile layer, a foam inner layer, and a textile outer layer. In one form, the foam is porous to allow moisture (e.g., sweat) to pass through the strip. In one form, the skin-contact layer of the strip is formed of a material that helps to absorb moisture from the user's face. In one form, the textile outer layer includes a loop material for engagement with a hook material portion.

[0315] In some forms of this technology, the positioning and stabilizing structure 1300 includes an extendable strip, such as an elastically extendable strip. For example, the strip may be configured to be taut in use and to guide force to pull the display screen 1220 and / or the display unit housing 1205 toward a portion of the user's face, particularly close to the user's eyes and in line with their field of vision. In one example, the strip may be configured as a tie.

[0316] In one form of the present technology, the positioning and stabilizing structure 1300 includes a first lacing strap that is configured and arranged such that, in use, at least a portion of its lower edge passes over the supraaural base of the user's head and covers a portion of the parietal bone without covering the occipital bone.

[0317] In one form of the present technology, the positioning and stabilizing structure 1300 includes a second tether that is configured and arranged such that, in use, at least a portion of its upper edge passes below the subauricular base of the user's head and covers or is located below the occipital bone of the user's head.

[0318] In one form of the present technology, the positioning and stabilizing structure 1300 includes a third lacing strap that is configured and arranged to interconnect the first and second lacing straps to reduce the tendency of the first and second lacing straps to move apart from each other.

[0319] In some forms of this technology, the positioning and stabilizing structure 1300 includes a flexible and, for example, non-rigid strip. An advantage of this is that the strip provides greater comfort against the user's head.

[0320] In some forms of this technology, the positioning and stabilizing structure 1300 includes strips configured to be breathable to allow wet vapor to pass through the strips.

[0321] In some forms of this technology, a system is provided comprising more than one positioning and stabilizing structure 1300, each configured to provide a holding force corresponding to a range of different sizes and / or shapes. For example, the system may include one form of positioning and stabilizing structure 1300 suitable for large-sized heads but not for small-sized heads, and another form of positioning and stabilizing structure suitable for small-sized heads but not for large-sized heads.

[0322] In some forms, the positioning and stabilizing structure 1300 may include a cushioning material (e.g., a foam pad) for contact with the user's skin. The cushioning material can provide additional abrasion resistance to the positioning and stabilizing structure 1300, especially if the positioning and stabilizing structure 1300 is made of a rigid or semi-rigid material.

[0323] Temporal connector

[0324] like Figure 5B As shown, some forms of the positioning and stabilizing structure 1300 include temporal connectors 1250, each temporal connector 1250 which can cover a corresponding one in the user's temporal bone during use. A portion of the temporal connector 1250 contacts an area of ​​the user's head near the supraacus base (i.e., above each of the user's ears) during use.

[0325] The temporal connector 1250 may be an outer portion of the positioning and stabilizing structure 1300, since each temporal connector 1250 is positioned on the left or right side of the user's head.

[0326] In some forms, the temporal connector 1250 may extend in the anteroposterior direction and may be substantially parallel to the sagittal plane.

[0327] In some configurations, the temporal connector 1250 may be attached to the display unit housing 1205. For example, the temporal connector 1250 may be attached to the outside of the display unit housing 1205.

[0328] In some forms, the temporal connector 1250 may be arranged in use to generally run along or parallel to the Frankfurt plane of the head and extend above the cheekbone (e.g., above the user's cheekbone).

[0329] In some forms, the temporal connector 1250 can be positioned against the user's head, similar to the temple of eyeglasses, and positioned higher than the antihelix of each ear.

[0330] In some forms, the temporal connector 1250 may have a generally elongated and flat configuration. In other words, the length and width (in the direction from top to bottom in the paper plane) of each temporal connector 1250 are much greater than its thickness (in the direction into the paper plane).

[0331] In some forms, the temporal connector 1250 may each have a three-dimensional shape with curvature along all three axes (X, Y, and Z). While the thickness of each temporal connector 1250 may be substantially uniform, its height varies throughout its length. The shape and size of each temporal connector 1250 are designed to fit snugly to the user's head so as to remain unobtrusive and maintain a low profile (e.g., not appearing too bulky).

[0332] In some forms, the temporal connector 1250 may be made of a rigid or semi-rigid material, which may include plastic, thermoplastic polyester elastomer, or another similar material. This rigid or semi-rigid material may be self-supporting and / or able to maintain its shape without wear. This allows the user to more intuitively or clearly understand how to use the positioning and stabilizing structure 1300, and contrasts with a completely loose positioning and stabilizing structure 1300 that does not maintain its shape. Maintaining the temporal connector 1250 in its in-use state before use prevents or limits deformation when the user wears the positioning and stabilizing structure 1300, and allows the user to quickly assemble or wear the head-mounted display system 1000.

[0333] In some forms, the temporal connector 1250 can be a reinforcement, which allows tension to be transmitted more effectively (e.g., directly) through the temporal connector 1250, since the reinforcement limits the extent of elongation or deformation of the arm during use.

[0334] In some forms, the temporal connector 1250 may be at least partially flexible in one direction and more rigid in another. The user can bend or flex the temporal connector more in one direction than in the other. For example, the temporal connector 1250 may be at least partially flexible along an axis substantially parallel to the user's sagittal plane (e.g., in the vertical direction during use). This allows the temporal connector 1250 to conform to the shape of the user's head by moving laterally toward or away from the user's head. The user can also make multiple adjustments along the length of the temporal connector 1250 to correspond to various structures along the user's head. However, bending along an axis substantially parallel to the user's coronal plane (e.g., extending laterally during use) may be more difficult. The temporal connector 1250 can resist bending in the vertical direction.

[0335] In some forms, the positioning and stabilizing structure 1300 can be designed so that it is "out of the box" and typically in its in-use configuration. Additionally, the positioning and stabilizing structure 1300 can be arranged to retain its in-use shape once unpacked (e.g., because reinforcements can be formed to maintain the shape of a portion of the positioning and stabilizing structure 1300). Advantageously, because the shape of the positioning and stabilizing structure 1300 is generally curved, closely resembling the rear portion of a user's head, the user can clearly understand the orientation of the positioning and stabilizing structure 1300. That is, the positioning and stabilizing structure 1300 is typically dome-shaped.

[0336] In some forms, flexible and / or elastic materials may be provided around the rigid or semi-rigid material of the temporal connector 1250. Flexible materials can provide a more comfortable fit against the user's head, thereby improving abrasion resistance and providing a soft contact with the user's face. In one form, the flexible material is a textile sleeve permanently or removably attached to each temporal connector 1250.

[0337] In one form, textile overlays can be molded onto at least one side of the reinforcement. In another form, the reinforcement can be formed separately from the elastic component, and then a socket formed of user contact material (e.g., Breath-O-Prene™) can be wrapped or slidably covered onto the reinforcement. In alternative forms, the user contact material can be provided to the reinforcement via adhesives, ultrasonic welding, stitching, hook and loop materials, and / or bolt connectors.

[0338] In some forms, the user contact material can be on both sides of the reinforcement, or alternatively, it can be on only the side of the reinforcement that contacts the user (e.g., the side that contacts the user) to reduce the volume and cost of the material.

[0339] In some forms, the temporal connector 1250 is made of a flexible material (e.g., textiles) that can comfortably fit against the user's skin and does not require additional layers to improve comfort.

[0340] Some forms of the positioning and stabilizing structure 1300 may consist only of the temporal connector 1250. The shape of the temporal connector 1250 may resemble that of the temple or arm of an eyeglass and may rest against the user's head in a similar manner. For example, the temporal arm 1250 may provide a force directed outwards towards the user's head (e.g., towards the corresponding temporal bone).

[0341] Rear support section

[0342] like Figure 5B As shown, some forms of the positioning and stabilizing structure 1300 may include a rear support, such as a rear support portion 1350, for helping to support the display screen 1220 and / or display unit housing 1205 near the user's eyes. The rear support portion 1350 can help secure the display screen 1220 and / or display unit housing 1205 to the user's head so that the display screen 1220 is properly oriented near the user's eyes.

[0343] In some configurations, the rear support portion 1350 may be connected to the display unit housing 1205 via the temporal connector 1250.

[0344] In some configurations, the temporal connector 1250 can be directly connected to the display unit housing 1205 and the rear support portion 1350.

[0345] In some forms, the rear support portion 1350 may have a three-dimensional contour curve to conform to the shape of the user's head. For example, the three-dimensional shape of the rear support portion 1350 may have a generally circular three-dimensional shape, which is adapted to cover part of the parietal and occipital bones of the user's head during use.

[0346] In some forms, the posterior support portion 1350 may include a three-dimensional shape curved about at least two axes. For example, the final portion of the posterior support portion 1350 (e.g., the portion configured to cover the user's occipital bone) may include a concave shape relative to the user's occipital bone. This helps the posterior support portion 1350 "cup-support" the back of the user's head to provide a secure fit. Additionally, the posterior support portion 1350 may be curved about an axis substantially parallel to the user's coronal plane. For example, this second curvature may be about an axis substantially perpendicular to the axis of the first curvature (i.e., the segment of the posterior support configured to cover the user's occipital bone). The segment with the second curvature may extend from the corresponding temporal connector 1250. Thus, this segment may cover the user's temporal bone and / or the user's occipital bone. Viewed from the side (e.g., in...) Figure 5B In the middle), the second curvature can be positive (e.g., "concave upward"). This can be the opposite of the curvature in the temporal connector 1250, although these curvatures can be about substantially parallel axes. For example, as in Figure 5B As observed, the curvature of the temporal connector 1250 can be negative (e.g., "concave downward"). This allows each temporal connector 1250 to bend around the user's corresponding ear.

[0347] In some forms, the back support portion 1350 can be at least partially reinforced so that the circular shape is maintained even when the user is not wearing it. This helps the user put on the back support portion 1350 because the rigidity limits tangling.

[0348] In one form, stiffness can provide “elasticity” to the rear support portion 1350. For example, the rear support portion 1350 can “bounce” after being compressed. In other words, the rear support portion 1350 can be flexible enough to fold, but once the force is removed, the rear support portion 1350 returns to its original shape (e.g., a three-dimensional circular shape).

[0349] In some configurations, the rear support portion 1350 may be the rear portion of the positioning and stabilizing structure 1300. The rear support portion 1350 may provide at least partially forward-directing anchoring force.

[0350] In some forms, the lower segment 1320 of the posterior support portion 1350 is the lowermost part of the positioning and stabilizing structure 1300. For example, the posterior support portion 1350 may contact the area of ​​the user's head between the occipital bone and the trapezius muscle. The posterior support portion 1350 may hook onto the lower edge of the occipital bone (e.g., the occipital portion). The posterior support portion 1350 may provide an upward and / or forward force to maintain contact with the back of the user's head.

[0351] In some configurations, the lower section 1320 of the rear support portion 1350 is the lowest part of the entire head-mounted display system 1000. For example, the rear support portion 1350 may be positioned at the base of the user's neck (e.g., covering the occipital bone and trapezius muscle, which are lower than the user's eyes), such that the rear support portion 1350 is lower than the display screen 1220 and / or the display unit housing 1205.

[0352] In some configurations, the upper section 1310 can cover the parietal bone when in contact with the user's head. As described above, the circular shape of the rear support portion 1350 allows the rear support portion 1350 to lie substantially flat on the user's head, while the lower section 1320 contacts the user's head.

[0353] In some forms, the back support portion 1350 may include padding material that can contact the user's head (e.g., covering the area between the occipital bone and the trapezius muscle). The padding material can provide additional comfort to the user and limit the imprints caused by the back support portion 1350 pulling on the user's head.

[0354] In some configurations, the rear support portion 1350 may be made of textile and / or foam materials. These materials may be biocompatible and comfortable for the user's head.

[0355] In one embodiment, the rear support portion 1350 may be constructed of foam material at least partially covered by a fabric material. The outer fabric material provides a comfortable feel against the user's skin. The inner foam layer allows the rear support portion 1350 to compress and enhance comfort.

[0356] Forehead support

[0357] like Figure 5A and Figure 5B As shown, some forms of the positioning and stabilizing structure 1300 may include a forehead support 1360 that, in use, contacts the user's head above the eyes. For example, the forehead support 1360 may cover the user's frontal bone. In some forms, the forehead support 1360 may also be positioned higher than the sphenoid bone and / or temporal bone. The forehead support 1360 may also be positioned higher than the user's eyebrows.

[0358] In some forms, the forehead support 1360 may be the front portion of the positioning and stabilizing structure 1300 and may be positioned more forward on the user's head than any other portion of the positioning and stabilizing structure 1300. The rear support portion 1350 may provide at least partially rearward-directed forces.

[0359] In some forms, the forehead support 1360 may include a cushioning material (e.g., textiles, foam, silicone, etc.) that comes into contact with the user and helps limit imprints caused by the strips of the positioning and stabilizing structure 1300. The forehead support 1360 and the interface connection structure 1100 can work together to provide comfort for the user.

[0360] In some forms, the forehead support 1360 may be separate from the display unit housing 1205 and may contact the user's head at a different location than the display unit housing 1205 (e.g., a higher location).

[0361] In some configurations, the forehead support 1360 can be adjusted to allow the positioning and stabilization structure 1300 to adapt to the shape and / or configuration of the user's face.

[0362] In some forms, the temporal connector 1250 may be coupled to the forehead support 1360 (e.g., on the lateral side of the forehead support 1360). The temporal connector 1250 may extend at least partially in a downward direction to be coupled to the posterior support portion 1350.

[0363] In some forms, the positioning and stabilizing structure 1300 may include multiple pairs of temporal connectors 1250. For example, one pair of temporal connectors 1250 may be coupled to the forehead support 1360, and another pair of temporal connectors 1250 may be coupled to the display unit housing 1205.

[0364] In some forms, the forehead support 1360 may be positioned at an angle generally parallel to the user's forehead to provide improved comfort. For example, the forehead support 1360 may be positioned to cover the frontal bone and be substantially parallel to the coronal plane. Positioning the forehead support substantially parallel to the coronal plane can reduce the likelihood of pressure sores caused by uneven presentation.

[0365] In some forms, the forehead support 1360 can be offset from the rear support that contacts the back of the user's head (e.g., the area covering the occipital bone and trapezius muscles). In other words, the axis along the rear strip does not intersect the forehead support 1360, and the forehead support 1360 can be positioned lower and further forward than the axis along the rear strip. The offset created between the forehead support 1360 and the rear strip can generate a torque against the weight of the display screen 1220 and / or the display unit housing 1205. A larger offset can generate a larger torque and thus better help maintain the correct position of the display screen 1220 and / or the display unit housing 1205. The offset can be increased by moving the forehead support 1360 closer to the user's eyes (e.g., further forward and lower along the user's head) and / or by increasing the angle of the rear strip to make it more vertical.

[0366] Adjustable strip

[0367] The various parts of the positioning and stabilizing structure 1300 may be adjustable to apply selective tensile forces to the display screen 1220 and / or the display unit housing 1205 in order to fix the position of the display screen 1220 and / or the display unit housing 1205.

[0368] In some forms, the display unit housing 1205 may include at least one ring or eyelet 1254, and at least one of the temporal connectors 1250 may pass through the ring and fold back (e.g., in...). Figure 4B The middle diagram shows, but is applicable to Figure 5A and Figure 5BThe length of the strip passing through the positioning and stabilizing structure 1300 of the corresponding eyelet 1254 can be selected by the user to adjust the tensile force. For example, a longer length passing through the eyelet 1254 can provide a larger tensile force.

[0369] In some forms, at least one of the temporal connectors 1250 may include an adjustment portion 1256 and a receiving portion 1258. The adjustment portion 1256 may be positioned through an eyelet 1254 on the display unit housing 1205 and may be coupled to the receiving portion 1258 (e.g., by folding itself back). The adjustment portion 1256 may include a hook material, and the receiving portion 1258 may include a loop material (or vice versa), such that the adjustment portion 1256 can be removably held in a desired position. In some instances, the hook and loop materials may be Velcro.

[0370] In some forms, the strip may be at least partially made of a flexible and / or elastic material that can conform to the shape of the user's head and / or allow the adjustment portion to pass through the eyelet 1254. For example, the adjustment portion 1256 may be made of an elastic textile that can provide elastic tensile force. The remainder of the temporal connector 1250 may be made of the aforementioned rigid or semi-rigid materials (although additional sections of the temporal connector 1250 may also be made of flexible materials).

[0371] Top strip section

[0372] In some forms, the positioning and stabilizing structure 1300 may include a top strip portion that can cover the upper area of ​​the user's head.

[0373] In some configurations, the top strip may extend between the front portion of the head-mounted display system 1000 and the rear portion of the head-mounted display system 1000.

[0374] In some forms, the top strip can be made of a flexible material and can be configured to complement the shape of the user's head.

[0375] In some configurations, the top strip portion may be connected to the display unit housing 1205. For example, the top strip portion may be connected to the upper surface 1230. The top strip portion may also be connected to the display unit housing 1205 near the rear end of the display unit housing 1205.

[0376] In some configurations, the top strip portion may be attached to the forehead support 1360. For example, the top strip portion may be attached to the forehead support 1360 near its upper edge. The top strip portion may be connected to the display unit housing 1205 via the forehead support 1360.

[0377] In some configurations, the top strip portion may be connected to the rear support portion 1350. For example, the top strip portion may be connected near the upper edge of the rear support portion 1350.

[0378] In some versions, the top strip can cover the frontal and parietal bones of the user's head.

[0379] In some forms, when the top strip portion extends between the front and rear portions of the head-mounted display system 1000, the top strip portion may extend along the sagittal plane.

[0380] In some forms, the top strip portion may be subjected to a tensile force oriented at least partially in the upward direction, which can counteract gravity.

[0381] In some forms, the top strip portion may be adjustable to apply selective tensile force to the display screen 1220 and / or display unit housing 1205 in order to fix the position of the display screen 1220 and / or display unit housing 1205.

[0382] In some forms, the display unit housing 1205 and / or forehead support 1360 may include at least one ring or eyelet 1254 through which a top strip portion may pass and fold back. The length of the top strip portion passing through the eyelet 1254 can be selected by the user to adjust the tensile force provided by the positioning and stabilizing structure 1300. For example, passing a longer length of the top strip portion through the eyelet 1254 may provide a greater tensile force.

[0383] In some forms, the top strip portion may include an adjustment portion and a receiving portion. The adjustment portion may be positioned through eyelet 1254 and may be attached to the receiving portion (e.g., by folding back on itself). The adjustment portion may include a hook material, and the receiving portion may include a loop material (or vice versa), such that the adjustment portion can be removably held in the desired position. In some instances, the hook material and loop material may be Velcro.

[0384] Interface connection structure

[0385] Figures 7A to 7DA head-mounted display system 1000 according to an example of the present technology is illustrated. The head-mounted display system 1000 includes a head-mounted display unit 1200, which includes a display unit housing 1205, and the display unit housing 1205 includes a display. The display may be as described elsewhere herein. The head-mounted display unit 1200 also includes an interface connection structure 1100 attached to the display unit housing 1205, and the interface connection structure 1100 may be configured and arranged to be relative to a user's face during use. The head-mounted display system 1000 also includes a positioning and stabilization structure 1300, which may be configured and arranged to hold the head-mounted display unit 1200 in an operable position on the user's head during use. The head-mounted display system 1000 may additionally have any of the features, configurations, aspects, functions, etc., as described elsewhere herein. Figures 8A to 8C A view of an interface connection structure 1100, an example of the present technology, is shown. The interface connection structure 1100 can be configured to be attached to the display unit housing 1205 of a head-mounted display system 1000, and can also be removably attached to the display unit housing 1205. The interface connection structure 1100 can be positioned around the periphery of a user's eye area during use, for example, around substantially the entire periphery.

[0386] Face joint and base frame

[0387] The interface connection structure 1100 may include a face-engaging portion 1110 configured to engage with a user's face in use. The face-engaging portion 1110 may be flexible and elastic. In some instances, the face-engaging portion 1110 is at least partially formed of an elastomeric material (e.g., silicone or TPE). The face-engaging portion 1110 may include one or more pads, which may be formed of, for example, foam. The face-engaging portion 1110 may include a face-engaging membrane that may at least partially surround or cover the pads. The face-engaging membrane 1116 may be formed of an elastomeric material (e.g., silicone or TPE).

[0388] Any suitable face bonding portion 1110 is envisioned for the head-mounted display system 1000. It should be understood that, unless the context otherwise requires, face bonding portions described elsewhere herein (such as those referenced in [reference]) are not intended to be used in this document. Figures 4A to 4B or Figures 5A to 5B Any of the features described above can be applied to Figures 7A to 7D or Figures 8A to 8C The interface connection structure 1100 is shown.

[0389] The interface connection structure 1100 may further include a base portion 1101 configured and arranged to support the face engagement portion 1110. This base portion 1101 may be configured and arranged to connect to the display unit housing 1205 of the head-mounted display system 1000. The base portion 1101 may be attached to the display unit housing 1205 in use, for example, by a releasable snap-fit, press-fit, or permanent attachment. In the illustrated example, the face engagement portion 1110 is attached to the base portion 1101. In the case of the interface connection structure 1100 (which is arranged around the entire periphery of the user's eye area in use), the base portion 1101 may also be arranged around the entire periphery of the user's eye area. More generally, the base portion 1101 may have a shape corresponding to the shape of the face engagement portion 1110, and may have a portion aligned with the user's forehead in use, a portion aligned with the side of the user's face outside the user's eyes, a portion aligned with the user's cheek, and... Figures 7A to 7D In the example shown, the base portion 1101 also includes a portion corresponding to the user's nasal region. In this example, the base portion 1101 extends inward along a path relative to the cheek portion 1140 and intersects the midsagittal plane during use, for example, near the user's nasal protuberance.

[0390] The face joint portion 1110 or a portion thereof may be overmolded onto the frame portion 1101. The face joint portion 1110 or a portion thereof may be formed of an elastomeric material such as silicone or TPE and may be overmolded onto the frame portion 1101. The frame portion 1101 may be formed of a substantially rigid or semi-rigid material such as polycarbonate, polyethylene, ABS, polypropylene, nylon, etc. In other instances, the face joint portion 1110 may be attached to the frame portion 1101 by means other than overmolding, such as by adhesives or other bonding, snap-fit, press-fit, hook-and-loop connection, or any other suitable connection.

[0391] The base portion 1101 may be configured to support the face joint portion 1110 and may be more rigid than the face joint portion 1110. The base portion 1101 may be formed of a material that is more rigid than the material forming the base portion 1101. The base portion 1101 may additionally or alternatively include a shape that requires greater force to deform than the face joint portion 1110.

[0392] The face bonding portion 1110 and the base portion 1101 can be formed together as a single component that can be releasably attached to the head-mounted display unit 1200, can be replaceable, and can be provided to the user in different sizes and / or configurations.

[0393] Special Reference Figures 7A to 7D and Figures 8A to 8CIn this example, the interface connection structure 1100 includes a pair of cheek portions 1140 configured and arranged to engage with a user's cheeks in use. In this example, the facial engagement portion 1110 is also configured to engage with the user's face on the lateral side of the user's eyes and further configured to engage with the user's forehead in use. The portion of the user's face engaging with the lateral side of the user's eyes can be identified as a sphenoid portion 1170. That is, the interface connection structure 1100 may include a pair of sphenoid portions 1170 configured to engage with the sphenoid region of the user's face in use. The portion engaging with the user's forehead can be identified as a forehead portion 1175. That is, the interface connection structure 1100 may include a forehead portion configured and arranged to engage with the user's forehead in use. The facial engagement portion 1110 may engage with the user's face in areas covering the user's nose, maxilla, zygomatic bone, sphenoid bone, and frontal bone. For example, the facial engagement portion 1110 may... Figure 4D The user's face is joined in the area shown.

[0394] Immersive mode and non-immersive mode

[0395] In some instances of this technology, the base portion 1101 defines at least one opening 1105, which is positioned within the user's field of vision around the periphery of the user's eye area. Figures 7A to 7D and Figures 8A to 8C The interface connection structure 1100 shown includes an opening 1105. This interface connection structure 1100 can be constructed and arranged to switch between a non-immersive mode and an immersive mode. In the non-immersive mode, the user can see through the opening 1105. In the immersive mode, light may be substantially blocked from passing through the opening 1105.

[0396] When a user switches between virtual reality and augmented or mixed reality using the head-mounted display system 1000, the ability to switch between non-immersive and immersive modes can advantageously enhance the user experience. In some scenarios, the head-mounted display system 1000 can be used in non-immersive applications to view the world around the user through the displays in the head-mounted display system 1000, such as during augmented or mixed reality applications. However, during such use, the interface connection structure 1100, which completely encloses the periphery of the user's eye area and does not allow peripheral vision, may cause motion sickness and / or excessive fog, sweat, and / or heat in some users, especially during strenuous use (such as gaming and exercise). Additionally or alternatively, the lack of peripheral vision may prevent users from interacting with their surroundings or make it more difficult for users to interact with their surroundings, for example, when using a keyboard and mouse while using the head-mounted display system 1000. Conversely, in scenarios where the head-mounted display system 1000 is used for immersive applications where the user is not intended to view the real world, the light from the outside world reaching the user's eyes or the user's ability to see the real world through peripheral vision may adversely affect the user's sense of immersion in the experience.

[0397] One approach to addressing the aforementioned issues is to use separate head-mounted display systems 1000 or interface connection structures 1100 tailored to each application, such as an "open" interface connection structure 1100 for non-immersive use and a "closed" interface connection structure 1100 for immersive use. However, this requires the user to have multiple head-mounted display systems 1000 or interface connection structures 1100, and switching between them can be time-consuming or inconvenient. The head-mounted display system 1000 or interface connection structure 1100 according to an example of this technology can advantageously allow the user to quickly switch between immersive and non-immersive modes without removing the head-mounted display system 1000.

[0398] Protective cover for openings

[0399] In some instances (such as) Figures 7A to 7D and Figures 8A to 8C In the example shown, the interface connection structure 1100 may include at least one shield 1150 configured and arranged to block light from passing through at least one opening 1105. The shield 1150 can be manipulated by a user to switch the interface connection structure 1100 to a non-immersive mode by substantially unblocking the opening 1105. Additionally, the shield 1150 can be manipulated by a user to switch the interface connection structure 1100 to an immersive mode by substantially blocking the opening 1105.

[0400] For specific references Figures 8A to 8CThe shield 1150 may be attached to the base portion 1101 to convert the interface connection structure 1100 into an immersion mode. The shield 1150 may also be removed from the base portion 1101 to convert the interface connection structure 1100 into a non-immersion mode. The shield 1150 may be substantially rigid. In examples, the shield 1150 may be formed of polycarbonate, polyethylene, ABS, polypropylene, nylon, etc. Alternatively, the shield 1150 may be semi-rigid or flexible. In other examples, the shield 1150 may be formed of an elastomeric material such as silicone or TPE. The shield 1150 may be formed of the same material as the base portion 1101, or it may be formed of a different material.

[0401] The shield 1150 can be constructed and arranged to form a snap-fit ​​connection with the base frame portion 1101 during attachment to the base frame portion 1101. Additionally or alternatively, the base frame portion 1101 and the shield 1150 are constructed and arranged such that the shield 1150 is magnetically attracted to the base frame portion 1101. Figures 8A to 8C In the illustrated example, the shield 1150 is magnetically attracted to the base portion 1101 to aid in alignment of the shield 1150 with the base portion 1101, and the shield 1150 is also configured to form a snap-fit ​​connection with the base portion 1101. Advantageously, the magnetic attraction prevents or at least reduces any difficulty that may arise in aligning the shield 1150 with the opening 1105 because the user cannot see the exterior of the interface connection structure 1100 while wearing the head-mounted display system 1000. After alignment and attachment, the mechanical snap-fit ​​attachment securely holds the shield 1150 to the base portion 1101. In other examples, only snap-fit ​​attachments may be present, or only magnetic attachments may be present (e.g., if the magnetic attraction is strong enough). In further examples, alternative connection methods between the shield 1150 and the base portion 1101 may be provided, such as hook-and-loop connections or latch or clamp connections.

[0402] The shield 1150 may include at least one magnet 1154 (see Figure 8B The magnet 1154 can be positioned to be attracted to a corresponding magnet or ferromagnetic component in or on the base portion 1101. Figures 8A to 8C In the example shown, the base portion 1101 and the cover 1150 are constructed and arranged such that the cover 1150 is magnetically attracted to the base portion 1101 at opposite ends of the cover 1150. In this example, each cover 1150 includes a magnet 1154 at each of its respective ends.

[0403] In some instances, the shield 1150 includes at least one gripping portion 1159 to assist a user in gripping the shield 1150. The gripping portion 1159 may be part of the shield 1150 configured to make it easier for a user to grip the shield 1150, such as being shaped as part of a protrusion, or having a surface or feature that provides high friction during gripping. Figures 8A to 8C In the example shown, the gripping portion 1159 is at least partially formed by a curved portion of the cover 1150, which forms a protrusion that can be gripped by a user. In this particular example, the curved portion includes a recessed portion. The curved portion can be shaped to be easily gripped by the thumb or forefinger. The curved portion may also include or be adjacent to a protruding portion, which can also form a protrusion that can be gripped or engaged by the user's thumb or forefinger. Figures 8A to 8C In the example shown, the shield 1150 includes a pair of gripping portions 1159 each disposed at a corresponding end of the shield 1150, the pair of gripping portions 1159 being configured to assist a user in gripping the shield 1150 with their thumb and forefinger. This can advantageously provide a shield 1150 that can be easily manipulated (e.g., removed or attached) with only two fingers of one hand, thus providing good usability.

[0404] Also in Figures 8A to 8C In the example shown, the gripping portion 1159 is at least partially formed by a vent 1152, which is configured and arranged to allow airflow through the opening 1105 when the interface connection structure 1100 is in immersion mode. The gripping portion 1159 may be at least partially formed by a plurality of vents forming the vent 1152. The vents may be configured to provide texture to the gripping portion 1159, making it easier to grip. Compared to a smooth surface, the vents can provide increased friction, which can advantageously increase the ease with which a user can grip the gripping portion 1159.

[0405] ventilation

[0406] In some instances of this technology, the interface connection structure includes one or more vents 1152. These vents 1152 can advantageously allow heat and / or moisture to dissipate from the interior of the interface connection structure 1100. This may be highly desirable during intensive use of the head-mounted display system 1000.

[0407] In some instances, the shield 1150 includes at least one vent 1152, which is configured and arranged to allow airflow through the opening 1105 when the interface connection structure 1100 is in a closed configuration. In some instances, the shield 1150 may include multiple vents 1152. Figures 8A to 8CIn the example shown, each shield 1150 includes two vents 1152. In this example, one vent 1152 is located at the upper end of each shield 1150, and the other vent 1152 is located at the lower end of each shield 1150.

[0408] The vent 1152 may be formed by at least one vent hole formed in the protective cover 1152. In some instances, such as Figures 8A to 8C In the example shown, each vent 1152 is formed by multiple vent holes.

[0409] In some forms of this technology, the interface connection structure 1100 may include a vent cover portion 1155, which is configured and arranged to block light from passing through at least one vent 1152 by either blocking light from reaching the vent 1152 or by blocking light after it has passed through the vent 1152. In various instances, the vent cover portion 1155 may take a range of forms and positions. The vent cover portion 1155 can prevent light from reaching the user's eyes via the vent 1152. In some instances, a shield may include the vent cover portion 1155. Figure 9A A schematic cross-sectional view of a shroud 1150 including a vent cap portion 1155 is shown. In this example, the vent cap portion 1155 is part of the shroud 1150 and is positioned above the vent forming the vent 1152, blocking light from passing through the vent 1152. In other examples, the vent cap portion 1155 may block light from passing through the vent 1152. When the interface connection structure 1100 is in immersive mode, light leakage into the interior of the interface connection structure 1100 may interfere with the experience of using the head-mounted display system 1000. Advantageously, the vent cap portion 1155 blocks light through the vent 1152 while still allowing air to flow in and out of the vent 1152.

[0410] The vent cover portion 1155 can be positioned outside the vent 1152 relative to the periphery of the user's eye area, or it can be positioned inside the vent 1152 relative to the periphery of the user's eye area. Figure 9A The illustration shows an example where the vent cover portion 1155 is disposed outside the vent hole forming the vent 1152. Figures 8A to 8C In the example shown, the vent cover portion 1155 is located inside the vent 1152. As illustrated, the vent hole forming the vent 1152 is visible on the outside of the interface connection structure 1100, and the vent cover portion 1155 is located on the inside relative to the periphery of the user's eye area.

[0411] In some instances, the vent cap portion 1155 is integrally formed with the shield 1150. For example, the vent cap portion 1155 may be molded together with the rest of the shield 1150 in a single molding operation / injection. In other instances, the vent cap portion 1155 may be formed separately and attached to the shield 1150.

[0412] In other embodiments of this technology, the shield 1150 and the base frame portion 1101 together define at least one ventilation opening between the base frame portion 1101 and the edge of the shield 1150 in a closed configuration. This at least one ventilation opening may form at least one vent 1152 in such a configuration. Figure 9B An example of this arrangement is shown. In this example, the shield 1150 is larger than the opening 1105. The shield 1150 is schematically depicted as attached to the base frame portion 1101, but in practice it can be attached to the base frame portion 1101 in any suitable manner, such as by mechanical (e.g., snap-fit) or magnetic connection. In this example, the shield 1150 and the base frame portion 1101 together form a tortuous path 1156 in a closed configuration to allow airflow through the vent 1152 while blocking light from the outside of the interface connection structure 1100 from entering its interior and affecting the immersion of the head-mounted display system 1000.

[0413] exist Figure 9B In the illustrated example, the shield 1150 includes at least one shield protrusion 1157 projecting toward the base portion 1101 to at least partially form a tortuous path 1156. Also in this example, the base portion 1101 includes at least one base protrusion 1158 projecting toward the shield 1150 to at least partially form the tortuous path 1156. In other examples, further protrusions may be present from the base portion 1101 and / or the shield 1150, or the tortuous path 1156 may be formed in another manner, such as by forming a meandering path through other complementary shapes of the base portion 1101 and the shield 1150 that allows airflow but prevents light from reaching the user's eyes.

[0414] Structure and location of the opening

[0415] In some forms of this technology, at least one opening 1105 comprises a set of openings. In such instances, a shield 1150 may be constructed and arranged to block light from passing through the set of openings. The opening 1105 may be a single opening or a set of openings. In some instances, the base portion may include one or more rods, each of which is positioned between and partially defines an opening in the set of openings. Figures 8A to 8CIn the illustrated example, each opening 1105 is in the form of a set of openings, and the base portion 1101 includes a plurality of rods that partially define these openings. In some instances, the base portion 1101 includes a plurality of rods defining a lattice structure. This lattice structure may be, for example, a hexagonal lattice structure, or alternatively, any other suitable structure. The rods or other members or portions of the base portion 1101 that divide what would otherwise be a single large opening 1105 into a set of openings may also advantageously provide strength and / or stiffness to the base portion 1101 in the areas of the openings 1105. This can advantageously allow the base portion 1101 to maintain its shape and provide the necessary support to the face joint portion 1110, while also providing the openings 1105 to allow the user to use the interface connection structure 1100 in a non-immersive mode.

[0416] One or more openings 1105 (as appropriate) may be positioned around the interface connection structure 1100. In some instances, at least one opening 1105 is located in the front portion 1175 of the interface connection structure 1100. Figure 7C As shown, the interface connection structure 1100 includes a pair of openings 1105, one of which is located on either side of the interface connection structure 1100 in the forehead portion 1157. Advantageously, this allows the user to have at least partially unobstructed peripheral vision in the upward direction. In some instances, at least one opening 1105 is located in one of the sphenoid portions 1170 of the interface connection structure 1100. In some instances, such as Figure 7A and Figure 7B In the illustrated example, the interface connection structure 1100 includes a pair of openings 1105, each located in a corresponding one of the sphenoid bone portions 1170. Advantageously, this allows the user to have at least partially unobstructed peripheral vision in the lateral direction. In some instances, at least one opening 1105 is located in one of the cheek portions 1140 of the interface connection structure 1100. For example, as... Figure 7D As shown, the interface connection structure 1100 includes a pair of openings 1105, each located in a corresponding one of the cheek portions 1140. Advantageously, this allows the user to have at least partially unobstructed peripheral vision in the downward direction. At least some kind of peripheral vision in the downward direction can be particularly advantageous because it allows the user to more easily perform certain tasks in a non-immersive mode, such as interacting with objects (such as a keyboard or mouse) below eye level while viewing objects or content at eye level.

[0417] In some instances, such as Figures 8A to 8CIn the illustrated example, the interface connection structure 1100 may include a lower left opening 1105 and a lower right opening 1105. The lower left opening 1105 may be located in the left cheek portion 1140 of the cheek portion and the left sphenoid portion 1170 of the sphenoid bone portion. Similarly, the lower right opening 1105 may be located in the right cheek portion 1140 of the cheek portion and the right sphenoid portion 1170 of the sphenoid bone portion. Advantageously, in this arrangement, the openings 1105 may each provide peripheral vision in the lateral, downward, and lateral-downward directions. In some other embodiments, the interface connection structure 1100 may include a pair of openings 1105, each opening 1105 positioned on a respective outer side of the interface connection structure 1100, and each opening 1105 positioned at the forehead portion 1175 and within the corresponding sphenoid portion 1170 and the corresponding cheek portion 1140.

[0418] In some instances, such as Figures 8A to 8C In the example shown, the base portion 1101 does not have an opening 1105 in the forehead portion 1175 of the interface connection structure 1100. Furthermore, in this particular example, there is no opening 1105 above the user's eyes in the base portion 1101 of the interface connection structure 1101. The interface connection structure 1100 includes a wide opening 1105 below the user's eyes (e.g., in the lower portion of the sphenoid portion 1175 and the cheek portion 1140), but no opening above the user's eyes, which advantageously provides peripheral vision, contextual awareness, and a sense of grounding, while also blocking light from above.

[0419] In other instances, the interface connection structure 1100 includes an opening 1105 above the user's eyes, separate from the opening 1105 below the user's eyes, so that the user can block light from above while allowing peripheral vision below (if needed).

[0420] Regardless of the location of one or more openings 1105 on the interface connection structure 1100, the interface connection structure 1100 may include a shield 1150 corresponding to the opening 1105. The shield 1150 may be constructed and arranged to fill or cover the opening 1105.

[0421] Some existing head-mounted display systems 1000, designed for non-immersive uses such as augmented or mixed reality, include a forehead pad but are otherwise completely open at the periphery. Some users may find an interface connection structure 1100 that engages the entire periphery of their face around their eye area (e.g., forehead, sphenoid bone, and cheeks) more comfortable than an interface connection structure 1100 that only engages the forehead. This increased comfort may be due to the better pressure distribution provided by the "full-face" interface connection structure 1100 compared to a forehead pad alone.

[0422] Additional Immersive Mode Examples

[0423] In some forms of this technology, the interface connection structure 1100 may include one or more alternative shields 1150 for covering, filling or otherwise blocking the opening 1105 in an immersive mode of the interface connection structure 1100, or may include something other than shields 1150 to substantially prevent light from passing through the opening 1105.

[0424] In some instances, the shroud 1150 includes a curtain attached to the base frame portion 1101. At least a portion of the curtain is slidable relative to the base frame portion 1101 to substantially block the opening 1105 during transition of the interface connection structure 1100 to an immersive mode and substantially release the blocking of the opening 1105 during transition of the interface connection structure 1100 to a non-immersive mode. A user is able to pull the curtain past the opening 1105 to block the opening 1105 and is able to pull the curtain back past or push it back past the opening 1105 to release the blocking of the opening 1105, thereby transitioning the interface connection structure 1100 between immersive and non-immersive modes. The curtain may be opaque to block light. In some instances, the curtain is formed of a textile material, which can help provide a comfortable appearance for the interface connection structure 1100. The curtain may be breathable, which can help dissipate heat and moisture in immersive mode. In some instances, the curtain is elastically stretchable, which advantageously allows the curtain to be taut in immersive mode. The curtain can then be attached to the base frame section 1101 under tension in immersive mode.

[0425] In another example, the shield 1150 may slide relative to the base portion 1101. The shield 1150 may be constructed and arranged to move to substantially block the opening 1105 during the transition of the interface connection structure 1100 to an immersive mode, and to substantially release the blocking of the opening 1105 during the transition of the interface connection structure 1100 to a non-immersive mode. The shield 1150 may be substantially rigid and may be used as an opaque window. By way of example only, the shield 1150 may slide on a track or within a channel of the base portion 1101.

[0426] In some instances, the shield 1150 includes one or more rotatable portions rotatably connected to the base portion 1101. These rotatable portions can be rotated to a closed configuration to transition the interface connection structure 1100 to an immersive mode. Similarly, these rotatable portions can be rotated to an open configuration to transition the interface connection structure 1100 to a non-immersive mode.

[0427] In some instances, the shield 1150 includes a hinged door that can be opened to switch the interface connection structure 1100 to a non-immersive mode and closed to switch the interface connection structure 1100 to an immersive mode. The door can be hinged to the base portion 1101 to allow it to be pivotally opened and closed to switch between non-immersive and immersive modes. In some instances, the hinged door can be configured to fold itself for fixation in the non-immersive mode.

[0428] In some instances, the opening 1105 is filled by an electronic screen. This screen can be controlled to be opaque in immersive mode and substantially transparent in non-immersive mode. Advantageously, this option may eliminate the need for any direct physical interaction between the user and the interface connection structure 1100 to move a component onto or away from the opening 1105. In such instances, the screen can be an electro-optical device, such as an LCD screen capable of operating as transparent or opaque as needed. In some instances, the screen can be positioned within a transparent window that fills the opening.

[0429] Nose

[0430] Figure 10A and Figure 10B An interface connection structure 1100 according to another embodiment of the present technology is shown. In this embodiment, the interface connection structure 1100 includes a nose portion 1180 configured to engage with a user's nose in use. The nose portion 1180 may be configured to at least partially block light from reaching the user's eyes from the user's nasal region (e.g., blocking light from traveling upwards via a path close to the surface of the user's nose). The nose portion 1180 may, for example, be configured to engage with the front surface, upper surface, and / or lateral surface of the user's nose in use. The nose portion 1180 may be positioned between cheek portions 1140 of the interface connection structure 1100 and may span between the cheek portions 1140. In this embodiment, the nose portion 1180 is removable.

[0431] exist Figure 10A and Figure 10BIn the example shown, the interface connection structure 1100 is constructed and arranged to switch between a non-immersive mode and an immersive mode. In the non-immersive mode, the nose portion 1180 is removed from the interface connection structure 1100. In the immersive mode, the nose portion is attached to the interface connection structure between the cheek portions to engage the user's nose during use and essentially block light from reaching the user's eyes from the nasal area. In the non-immersive mode, the user can have some peripheral vision in the direction below their nose, or at least be able to see their nose in their peripheral vision. Some users of head-mounted display systems have used software that adds a "virtual nose" to the displayed content to help them feel grounded and avoid motion sickness. The ability to selectively remove the nose portion 1180 of the interface connection structure 1100 can provide a similar effect.

[0432] In particular, such as Figure 10B As shown, in this example, the nose portion 1180 of the interface connection structure 1100 includes a nasofacial engagement portion 1183 and a nasal underframe portion 1181. The nasal underframe portion 1181 can be configured to connect to the underframe portion 1101 of the interface connection structure 1100 to attach the nose portion 1180 to the interface connection structure 1100 during transition to an immersive mode. The nasal underframe portion 1181 can be configured to support the nasofacial engagement portion 1183 and can be substantially rigid. The nasofacial engagement portion 1183 can be flexible, and the nasal underframe portion 1181 can be more rigid than the nasofacial engagement portion 1183. The nasofacial engagement portion 1183 can be formed of an elastomeric material such as silicone, TPE, etc., and can be formed of a material also used for the engagement portion of the facial engagement portion 1110, which engages the cheek, sphenoid region, or forehead. The nose frame portion 1181 may be formed of ABS, polycarbonate, Hytrel, polypropylene, polyethylene, nylon or any suitable material, and may be formed of the same material as the frame portion 1101 that attaches to the display unit housing 1205.

[0433] The nose portion 1180 may include an outer side, the shape and size of which are designed to align with the cheek portion 1140 of the face engagement portion 1110 in immersive mode, to substantially prevent light from passing between the nose portion 1180 and the cheek portion 1140. Advantageously, this can provide an immersive user experience in immersive mode, wherein the nose portion 1180 can be removed to allow the interface connection structure 1100 to switch to a non-immersive mode.

[0434] refer to Figure 10A and Figure 10B The removable nasal portion 1180 described and referenced Figures 7A to 8CThe described openings 1105 are not mutually exclusive. In an example, the interface connection structure 1100 may include the opening 1105, the removable nose portion 1180, or both. Advantageously, in non-immersive mode, the interface connection structure 1100, having both the removable nose portion 1180 and openings 1105 elsewhere around the interface connection structure 1100, can obstruct the user's peripheral vision with minimal obstruction.

[0435] Similarly, Figure 10A and Figure 10B As shown, in this example, the nose portion 1180 includes a lower portion 1182 that can be positioned close to the user's nasal protuberance during use. The lower portion 1182 may include a concave, forward-facing surface and may be dome-shaped. For example, when viewed from below, the lower portion 1182 may typically be concave and dome-shaped, but may include complex curvatures and is not entirely hemispherical. In some instances, the lower portion 1182 may occupy space above, in front of, and / or to the outside of the user's nasal protuberance during use.

[0436] Additionally, in this example, the nose portion 1180 includes a first flap 1186 and a second flap 1186, each connected to the lower portion 1182. The first flap 1186 can be configured to engage a first outer side of the user's nose in use, and the second flap 1186 can be configured to engage a second outer side of the user's nose in use. In this example, the first flap 1186 and the second flap 1186 are separated by a slot.

[0437] The first and second wing plates 1186 can contact the user's nose along the nasal ridge and can extend toward the user's nasal bridge point. The first and second wing plates 1186 can extend to the user's nasal bridge point, or can only extend partially along the user's nasal ridge. For example, the nasal portion 1180 can be constructed and arranged to extend at least partially upward between the user's nasal protuberance and nasal bridge point. In some instances, the nasal portion 1180 can contact a large portion of the user's nasal ridge during use. The first wing plate 1186 can be located on a first side of the midsagittal plane of the user's head, and the second wing plate 1186 can be located on a second side of the midsagittal plane of the user's head. Figure 10A and Figure 10B In the example shown, the first wing 1186 and the second wing 1186 bridge between the cheek portion 1140 and the corresponding outer side of the user's nose in immersive mode.

[0438] Attachments for head-mounted display units

[0439] Figures 11 to 14A view of an interface connection structure 1100 and its components according to another embodiment of the present technology is shown. The interface connection structure 1100 is used in a head-mounted display system 1000 including a head-mounted display unit 1200. The head-mounted display unit 1200 may be as described elsewhere herein and may include a display unit housing 1205, which includes a display. In this example, the head-mounted display unit 1200 includes the interface connection structure 1100. The interface connection structure 1100 may be attached to the display unit housing 1205 in use. Furthermore, the interface connection structure 1100 may be constructed and arranged to be relative to the user's face in use and may be positioned around the user's eye area in use. The head-mounted display system 1000 may additionally have any of the features, configurations, aspects, functions, etc., described elsewhere herein. For example, the head-mounted display system 1000 may include a positioning and stabilization structure 1300 configured and arranged to hold the head-mounted display unit 1200 in an operable position on the user's head during use.

[0440] The interface connection structure 1100 may include a face engagement portion 1110 configured to engage with a user's face in use. The face engagement portion 1110 may be flexible and elastic. The face engagement portion 1110 may be at least partially formed of an elastomeric material such as silicone or TPE.

[0441] It should be understood that, unless the context otherwise requires, the interface connection structures and / or face joints described elsewhere in this document (such as references) are not intended to be used in this document. Figures 4A to 4B , Figures 5A to 5B or Figures 7A to 10B Any of the features described above can be applied to the interface connection structure 1100, such as... Figures 11 to 14 The interface connection structures shown are particularly suitable for use in head-mounted display systems 1000 configured for VR (e.g., reference 1100). Figures 4A to 4B or Figures 7A to 7D This is used in the described head-mounted display system. However, it should be understood that references... Figures 11 to 14 The described interface connection structure 1100 or its various features can be applied to a head-mounted display system 1000 configured for any of VR, MR, AR or other artificial realities.

[0442] The facial bonding portion 1110 may be at least partially formed of an elastomeric material, such as silicone or TPE. In some instances, the facial bonding portion 1110 may be at least partially formed of foam.

[0443] The facial engagement portion 1110 can be configured to engage with the user's face around the periphery of the user's eyes during use. The facial engagement portion 1110 can be configured to engage with the side of the user's face outside the user's eyes and engage with the user's forehead during use. The facial engagement portion 1110 can engage with the user's cheeks, the side of the user's face outside the user's eyes, and the user's forehead. The facial engagement portion 1110 can engage with the user's face in areas covering the user's nose, maxilla, zygomatic bone, sphenoid bone, and frontal bone. For example, the facial engagement portion 1110 can... Figure 4D The user's face is joined in the area shown. Figures 11 to 14 The face joint portion 1110 of the interface connection structure 1100 shown can be connected with... Figures 7A to 10B The user's face is joined in the same area as the face joining portion 1110 shown.

[0444] For details, please refer to the following: Figures 11 to 14 The facial engagement portion 1110 may, in some forms, include a nose portion 1180 configured to engage with a user's nose in use. This nose portion 1180 may be configured to at least partially block light from reaching the user's eyes from the user's nasal region (e.g., blocking light travels along a path near the surface of the user's nose). The nose portion 1180 may, for example, be configured to engage with the front surface, upper surface, and / or lateral surface of the user's nose in use. The nose portion 1180 may be as described in reference... Figures 7A to 10B Any of the above and / or may be described as referenced Figures 10A to 10B The removable.

[0445] exist Figures 11 to 14 In the illustrated example, the interface connection structure 1100 includes a base portion 1101. A face-fitting portion 1110 can be attached to this base portion 1101. In some embodiments, some or all of the face-fitting portions 1110 can be permanently attached to the base portion 1101 (e.g., by overmolding, adhesion, or permanent snap-fit). In this form, the base portion 1101 and the face-fitting portions 1110 form an integral part. In other embodiments, the face-fitting portions 1110 can be releasably attached to the base portion 1101.

[0446] The interface connection structure 1100 may include one or more clamps 1102. These clamps 1102 may be attached to the base portion 1101 and are configured to attach the interface connection structure 1100 to the display unit housing 1205 in use. Figures 11 to 14In the illustrated example, the fixture 1102 is formed separately from the base portion 1101. Advantageously, this allows the fixture 1102 to be formed from a different material and / or by a different manufacturing process than the base portion 1101. This also simplifies the manufacturing of the base portion 1101, which may be less complex due to the lack of an integral fixture. In some examples, multiple interface connection structures 1100 with different shapes and / or sizes can be produced, wherein all interface connection structures 1100 are configured to mate with the fixture 1102.

[0447] In some instances, the face-fitting portion 1110 and the base portion 1101 may comprise a single component configured and arranged to be releasably attached to the display unit housing 1205 using a clamp 1102. In some instances, the face-fitting portion 1110 and the base portion 1101 may be configured and arranged to be releasably attached to the display unit housing 1205 via another component or portion of the head-mounted display unit 1200 (such as a spacer or other intermediate component).

[0448] exist Figures 11 to 14 In the example shown, each of the one or more clamps 1102 is permanently attached to the base portion 1101. Figure 12 In the example shown, pin 1104 holds each clamp 1102 (described in more detail below). Additionally or alternatively, clamp 1102 may be glued to the base portion 1101. In the example shown in FIG. 10, clamp 1102 forms a permanent snap-fit ​​connection with the base portion 1101. In other examples, each of the one or more clamps 1102 may be removably attached to the base portion 1101, for example, using a removable pin 1104 or a removable snap-fit.

[0449] Each of the clamps 1102 may be formed of a different material from the base portion 1101, or it may be formed of the same material. In some instances, the clamps 1102 are formed of thermoplastic materials (e.g., acrylonitrile butadiene styrene (ABS), polyethylene (PE), polycarbonate (PC), nylon, etc.). In other instances, the clamps 1102 are formed of metals (e.g., aluminum, stainless steel, spring steel, etc.). In some instances, the clamps 1102 are formed of magnets and configured to be magnetically attached to a corresponding magnet or ferromagnetic material disposed on the display unit housing 1205.

[0450] In some instances, the base frame portion 1101 is formed of a different material than the face joint portion 1110. Figures 11 to 14In the example shown, the base portion 1101 is more rigid than the face-joining portion 1110. The base portion 1101 may be formed of a thermoplastic material (e.g., ABS, PE, PC, nylon, etc.). The face-joining portion 1110 may be formed of an elastomeric material and / or a foam material, as described elsewhere. The base portion 1101 may serve as at least a base for the face-joining portion 1110, for example, by providing a supporting structure. The face-joining portion 1110 may be flexible, soft, and / or compressible, as described elsewhere. The base portion 1101 can hold the face-joining portion 1110 in a shape ready for a comfortable, stable, and effective (e.g., light-blocking) engagement with the user's face, and helps maintain it in good engagement with the user's face even during vigorous head movements.

[0451] The interface connection structure 1100 may include any number of clamps 1102, such as one, two, three, four or more. In some instances, the interface connection structure 1100 may also include other components or portions that may work in conjunction with one or more clamps 1102 to attach the interface connection structure 1100 to the display unit housing 1205 or other components of the head-mounted display unit 1200.

[0452] exist Figures 11 to 14 In the example shown, the interface connection structure 1100 includes a plurality of clamp attachment assemblies. Each clamp attachment assembly includes a clamp attachment portion and a corresponding clamp 1102 attached to that clamp attachment portion. The interface connection structure 1100 may include any number of clamp attachment assemblies, such as one, two, three, four or more. Each clamp 1102 may be attached as part of a clamp attachment assembly to the base portion 1101.

[0453] Figure 12 and Figure 14 A cross-sectional view of the interface connection structure 1100 is shown, each view passing through a clamp attachment assembly located in the upper portion of the respective interface connection structure 1100 (e.g., a portion configured to engage with a user's forehead). In each of these examples, in each clamp attachment assembly, the clamp attachment portion includes a clamp receiving portion 1103 configured to receive a clamp therein. In these examples, the clamp receiving portion 1103 may form a concave portion of the clamp attachment assembly, and the clamp 1102 may form a convex portion. In other examples, the configuration may be reversed, and the clamp attachment portion may form a convex portion of the assembly, and the clamp 1102 may form a concave portion of the assembly.

[0454] refer to Figures 11 to 13In the illustrated example, in each clamp attachment assembly, each clamp 1102 is attached to the clamp attachment portion by a pin 1104. Specifically, in each clamp attachment assembly, the pin 1104 passes through a hole in the base portion 1101 and is positioned through a hole 1106 in the clamp 1102. The clamp 1102 and / or the pin 1104 may also be glued to the base portion 1101, for example, to prevent accidental disassembly of the clamp attachment assembly. In this example, the clamp receiving portion 1103 includes a shape complementary to the shape of the portion of the clamp 1102 received in the clamp receiving portion 1103. The clamp receiving portion 1103 may also include a larger size than the clamp 1102 in one or more dimensions, provided that the clamp 1102 can still be received in the clamp receiving portion 1103 and attached to the base portion 1101.

[0455] exist Figures 11 to 14 In each of the examples shown, each clamp 1102 includes a first barb 1107 configured to form a snap-fit ​​connection with the display unit housing 1205. In other examples, the barb 1107 may be replaced by another suitable snap-fit ​​feature at the end of the clamp 1102, which may be selected based on the desired permanence of the snap-fit ​​connection or for any other reason. It should be understood that any suitable snap-fit ​​feature may be provided to the clamp 1102 in place of or in addition to the barb 1107. Figure 14 As shown, in this example, the clamp 1102 also includes a second barb 1107, which is configured to form a snap-fit ​​connection with the base portion 1101. That is, the clamp 1102 snaps into both the base portion 1101 and the display unit housing 1205 (permanently or removably).

[0456] The interface connection structure 1100 may include any number of clamps 1102. For example, the interface connection structure 1100 may include at least one clamp 1102 that is attached to the upper portion of the base portion 1101 during use and at least one clamp 1102 that is attached to the lower portion of the base portion 1101 during use. Figure 11 In the illustrated example, the interface connection structure 1100 includes a pair of clamps 1102 that are attached in use to the upper portion (e.g., in the forehead portion) of the frame portion 1101 and a pair of clamps 1102 that are attached in use to the lower portion (e.g., in the cheek portion) of the frame portion 1101. In other examples, the interface connection structure 1100 may include clamps 1102 at the outer portion of the interface connection structure 1100 (such as at the sphenoid portion of the interface connection structure 1100).

[0457] exist Figures 11 to 14In the examples shown, the facial bonding portion 1110 includes a facial bonding film 1114. In these examples, the facial bonding film 1114 is overmolded onto the frame portion 1101; however, in other examples, the facial bonding film 1114 may be glued or may be removably attached, for example, by press fitting. In these examples, the facial bonding film 1114 is formed of an elastomeric material, such as silicone or a thermoplastic elastomer. Furthermore, in these specific examples, the facial bonding portion 1110 includes a pad 1130. The transverse cross-section of the facial bonding film 1114 (e.g., Figure 12 and Figure 14 The cross-section shown (transverse to the length of the facial engagement portion 1110 surrounding the user's eye area) is shaped to at least partially curl around the pad 1130. In these examples, the pad 1130 is formed of foam, but may alternatively be formed of gel, silicone, air defining a sealed volume to serve as a pad, etc. In these examples, the facial engagement film 1114 at least partially covers the pad 1130. The facial engagement film 1114 may form a facial contact area configured to contact the user's face during use. Alternatively, the facial engagement film 1114, or more generally the facial engagement portion 1110, may be as described elsewhere herein.

[0458] clean

[0459] In some forms, the head-mounted display system 1000, or at least a portion thereof, is designed for use by a single user and for cleaning in the user's home, such as by washing with soap and water, without requiring specialized disinfection and sterilization equipment. Specifically, the positioning and stabilization structure 1300 and the interface connection structure 1100 are in direct contact with the user's head and are therefore designed to be cleanable.

[0460] In some other forms, components of the positioning and stabilization structure 1300 and the interface connection structure 1100 are used in laboratories, clinics, and hospitals, where a single head-mounted display can be reused on multiple people or used in medical procedures. In each of these laboratories, clinics, and hospitals, the head-mounted display or its associated components can be reprocessed and exposed to processes such as heat sterilization, chemical sterilization, and sterilization. Therefore, the design of the positioning and stabilization structure and the interface connection structure may require validation for mask sterilization and sterilization according to ISO 17664.

[0461] Materials can be selected to withstand reprocessing. For example, robust materials can be used in the positioning and stabilizing structure 1300 to withstand exposure to high-concentration disinfectant solutions and agitation by brushes. Furthermore, some components of the positioning and stabilizing structure are detachable and can be disconnected during use to improve reprocessing efficiency.

[0462] In some instances, the interface connection structure 1100 may come into contact with the user's head during use and may therefore become soiled (e.g., due to sweat). The interface connection structure 1100 may be designed to be removed from the display unit housing 1205 to provide the ability to remove it for cleaning and / or replacement. It may be desirable to clean the interface connection structure 1100 without wetting the positioning and stabilizing structure 1300. Alternatively or additionally, the positioning and stabilizing structure 1300 may become soiled due to contact with the user's head and may be removed independently of the interface connection structure 1100 for cleaning and / or replacement. In either case, this can be facilitated by allowing these components to be disconnected for this purpose.

[0463] In some instances, the cover (e.g., made of textiles, silicone, etc.) can be removably positioned over the interface connection structure and can be removed after each use for cleaning and / or replacement. The cover allows the interface structure 1200 to remain fixed to the display unit housing 1205 and provides a surface that can be easily cleaned after use.

[0464] In some forms, the overlap of the pad attachment portion 1120 and the pad support flange 1164 can limit the cleaning fluid from contacting the adhesive 1124 and / or the pad 1130 during the cleaning process.

[0465] external computer

[0466] In some forms, the head-mounted display system 1000 (e.g., VR, AR, and / or MR) can be used in conjunction with a separate device, such as a computer or video game console. For example, the display interface can be electrically connected to the separate device.

[0467] In some forms, at least some of the processing of the head-mounted display system 1000 can be performed by the separate device. The separate device may include a larger and / or more powerful processor that is not comfortable for the user to support (e.g., the processor of the separate device may be too heavy for the user to support comfortably on their head).

[0472] For example, ambient light surrounding the display interface can be light that closely surrounds the user, such as light in a room that is the same as and / or adjacent to the user, and / or natural light from the sun.

[0473] In some forms, ambient (e.g., acoustic) noise can be considered as the background noise level in the room where the user is located, rather than noise generated by, for example, the display device or the speakers connected to the display device. Ambient noise may be generated by sources outside the room.

[0474] leakage The term "leakage" would be considered as unintentional exposure to light. In one instance, leakage might be caused by an incomplete seal between the display unit and the user's face.

[0475] Radiated noise (acoustic) Radiated noise in this document refers to noise transmitted to the user by the surrounding air. In one form, radiated noise can be quantified according to ISO 3744 by measuring the sound power / sound pressure level of the object under discussion.

[0547] The shape of the structure

[0548] Products according to this technology may include one or more three-dimensional mechanical structures, such as mask pads or thrusters. The three-dimensional structure may be defined by two-dimensional surfaces. These surfaces may be distinguished using labels to describe associated surface orientation, location, function, or other characteristics. For example, the structure may include one or more of a front surface, a rear surface, an inner surface, and an outer surface. In another example, the seal-forming structure may include a face-contact (e.g., external) surface and separate non-face-contact (e.g., underside or internal) surfaces. In yet another example, the structure may include a first surface and a second surface.

[0549] To facilitate the description of the shape of three-dimensional structures and surfaces, we first consider points. p The cross-section of the surface passing through the structure. See also Figures 3A to 3E The diagram illustrates points on the surface. p Examples of cross-sections at the location, and the resulting planar curves. Figures 3A to 3E It also has an illustration. pThe outward normal vector at that location. p The outward normal vector at a point points away from the surface. In some instances, we describe the surface from the perspective of an imaginary little person standing upright on it.

[0550] One-dimensional curvature

[0551] Plane curves in p The curvature at a point can be described as having a sign (e.g., positive, negative) and magnitude (e.g., only at contact with) the curvature at that point. p (The reciprocal of the radius of the circle at the curve).

[0552] Positive curvature: If in p If the curve at a point turns towards the outward normal, then the curvature at that point will be taken as positive (if the imagined figure moves away from the point). p (Then they must go uphill). See also Figure 3A (and Figure 3B Compared to a relatively large positive curvature) and Figure 3B (and Figure 3A (Compared to a relatively small positive curvature). Such curves are often referred to as concave curves.

[0553] Zero curvature: If in p If the curve at point is a straight line, then the curvature will be taken as zero (if the imagined figure leaves point). p Then they can walk horizontally, without going up or down. (See also...) Figure 3C .

[0554] Negative curvature: If in p If the curve at a point deviates from the outward normal, then the curvature in that direction at that point will be negative (if the imagined figure moves away from the point). p (Then they must go downhill). See also Figure 3D (and Figure 3E Compared to a relatively small negative curvature) and Figure 3E (and Figure 3F (Compared to a relatively large negative curvature). Such curves are often referred to as convex curves.

[0555] Curvature of a two-dimensional surface

[0556] A description of the shape at a given point on a two-dimensional surface according to the present technology may include multiple normal cross sections. These multiple cross sections may cut through the surface in a plane including an outward normal (“normal plane”), and each cross section may be cut in different directions. Each cross section produces a planar curve with a corresponding curvature. The different curvatures at that point may have the same sign or different signs. Each curvature at that point has, for example, a relatively small magnitude. Figures 3A to 3EA planar curve in a plane can be an instance of multiple cross-sections at a specific point.

[0557] Principal curvature and principal direction: The direction of the normal plane where the curvature of the curve reaches its maximum and minimum values ​​is called the principal direction. Figures 3A to 3E In the example, the maximum curvature occurs Figure 3A In the middle, and the minimum curvature appears Figure 3E Therefore Figure 3A and Figure 3E It is the cross-section in the main direction. p The principal curvature at a point is the curvature along the principal direction.

[0558] Surface area: A set of connecting points on a surface. These points within a region may have similar characteristics, such as curvature or sign.

[0559] Saddle-shaped area: At each point, there are regions where the principal curvature has opposite signs, one positive and the other negative (depending on the direction the imagined person is turning, they could be going uphill or downhill).

[0560] Dome area: This refers to regions where the principal curvatures have the same sign at each point, such as regions where both are positive ("concave dome") or both are negative ("convex dome").

[0561] Cylindrical area: One of the principal curvatures is zero (or, for example, zero within manufacturing tolerances), while the other principal curvature is a non-zero region.

[0562] Planar area: Two of the surface regions have a principal curvature of zero (or, for example, zero within manufacturing tolerances).

[0563] Surface edge: The boundary or limit of a surface or area.

[0564] path: In some forms of this technique, "path" will be considered to mean a path in a mathematical-topological sense, such as a path on a surface from... f (0) to f (1) A continuous spatial curve. In some forms of this technique, a “path” can be described as a route or distance, including, for example, a set of points on a surface. (An imagined path for a person is the place where they walk on the surface, and is similar to a garden path).

[0565] Path length: In some forms of this technique, "path length" will be considered to refer to the length along the surface from f (0) to f(1) The distance, that is, the distance along the path on the surface. There can be more than one path between two points on the surface, and such paths can have different path lengths. (The path length of an imagined person would be the distance they must walk along the path on the surface).

[0566] Straight-line distance: Straight-line distance is the distance between two points on a surface, but it is independent of the surface itself. On a planar surface, there will exist paths with the same length as the straight-line distance between the two points. On a non-planar surface, there may not be paths with the same length as the straight-line distance between the two points. (For the imaginary reader, straight-line distance would correspond to a distance that is "in a straight line.")

[0567] hole

[0568] Surfaces can have one-dimensional pores, such as pores defined by planar curves or spatial curves. Thin structures with pores (e.g., films) can be described as having one-dimensional pores. See example. Figure 3F The structure shown has a one-dimensional hole defined by a planar curve on its surface.

[0569] The structure can have two-dimensional pores, such as pores defined by a surface. For example, an inflatable tire has two-dimensional pores defined by the inner surface of the tire. In another example, a bladder having a cavity for air or gel can have two-dimensional pores. In yet another example, a conduit can include a one-dimensional pore (e.g., at its inlet or outlet) and a two-dimensional pore defined by the inner surface of the conduit. See also Through Figure 3H The structure shown has a two-dimensional hole defined by the surface shown.
