[0002] not applicable Technical Field

[0003] 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

[0004] 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.

[0005] Immersive technology

[0006] 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.

[0007] 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.

[0008] Virtual Reality

[0009] 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).

[0010] 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.

[0011] 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 may 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] Portability

[0017] Fixed unit

[0018] 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).

[0019] Portable unit

[0020] 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.

[0021] Monitor connection

[0022] Integrated display screen

[0023] 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.

[0024] 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.

[0025] 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).

[0026] Removable display screen

[0027] In some forms, the display screen is a separate structure that can be removed from the VR device and used independently.

[0028] 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.

[0029] Portable electronic devices are typically lightweight and may not require positioning and stabilizing structures to exert significant force on the user's head.

[0030] Augmented Reality

[0031] In some forms, augmented reality (AR) is a computer-generated three-dimensional image or environment presented to the user.

[0032] 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.

[0033] 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).

[0034] 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.

[0035] This key difference between VR and AR can lead to different types of wearable electronic screens. As mentioned above, VR device users 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, AR device users 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 without a transparent screen (through which the user can see their real-world environment) can be configured to achieve AR by capturing 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.

[0036] 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.

[0037] Mixed Reality

[0038] 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.

[0039] Head-mounted display interface

[0040] 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.

[0041] 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.

[0042] 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 keep the display unit in place.

[0043] 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).

[0044] 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 keep the display unit in place. 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.

[0045] 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.

[0046] Interface connection structure

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 can be difficult to clean, potentially further limiting the system's comfort and usability.

[0051] 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.

[0052] 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.

[0053] Positioning and stability

[0054] 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.

[0055] 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.

[0056] Some other head-mounted display systems may be uncomfortable or impractical for this technology. For example, prolonged use of the system.

[0057] 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.

[0058] 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.

[0059] Material

[0060] Materials used in head-mounted display assemblies 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.

[0161] The positioning and stabilizing structure includes at least one cam mechanism that tensions the strip portion when the head-mounted display unit moves to a viewing position and releases the tension in the strip portion when the head-mounted display unit is lifted upward away from the viewing position.

[0162] The cam mechanism includes a cam, and one of the arms rotates the cam to operate the cam mechanism as the head-mounted display unit moves toward or away from the viewing position;

[0163] The cam mechanism is constructed and arranged to resist movement of the head-mounted display unit away from the viewing position when the head-mounted display unit is in the viewing position;

[0164] When the user lifts the head-mounted display unit away from the viewing position, the cam mechanism resists the movement of the head-mounted display unit away from the viewing position by initially increasing the tension in the strip portion, wherein after the initial increase in tension, the cam mechanism relieves the tension in the strip portion;

[0165] The cam mechanism operates to impart or allow relative movement between the corresponding ends of the front and rear portions of the strip section;

[0166] The cam mechanism includes a cam and a tether that connects one of the front and rear portions of the strip portion to the cam, wherein rotation of the cam during movement of the head-mounted display unit toward a viewing position pulls the corresponding front or rear portion toward the cam to increase tension in the strip portion; and

[0167] The cam mechanism includes a cam and a tether that connects the front portion of the strip portion to the rear portion of the strip portion. The cam is configured and arranged to engage the tether to pull the front and rear portions of the strip portion together as the head-mounted display unit moves toward the viewing position.

[0168] The tether is made of a flexible and stretchable material.

[0169] Another form of this technology includes a head-mounted display system for humans, comprising:

[0170] Head-mounted display units, including displays;

[0171] Control systems for operating head-mounted display systems; and

[0172] A positioning and stabilizing structure is configured to hold the head-mounted display unit in front of the user's eyes so that the display can be viewed by the user during use.

[0173] Head-mounted display systems can be mounted on helmets and can be configured for virtual reality displays, augmented reality displays, or mixed reality displays.

[0175] An electronic display screen configured to output multiple images to a user;

[0176] A display housing configured to at least partially accommodate an electronic display screen; and

[0177] A positioning and stabilizing structure is attached to the display housing and supports the display housing and electronic display screen in the operating position. The positioning and stabilizing structure is configured to provide force against the user's head to counteract the torque generated by the combined weight of the electronic display screen and the display housing, and to keep the position of the electronic display screen in front of the user's eyes when in the operating position.

[0178] The positioning and stabilizing structure is essentially as described in any of the examples disclosed herein.

[0179] Another form of this technology includes a positioning and stabilizing structure for supporting an electronic display screen of a head-mounted display interface. This positioning and stabilizing structure is configured to provide force against the user's head to counteract the torque generated by the weight of the electronic display screen and to maintain the electronic display screen in front of the user's eyes during use. This positioning and stabilizing structure includes:

[0180] A rear strip is configured to contact a region of the user's head located behind the coronal plane of the user's head, and the rear strip is configured to anchor the head-mounted display interface to the user's head.

[0181] Another aspect of this technology is a positioning and stabilizing structure configured to have a shape complementary to that of the intended wearer.

[0182] Another aspect of this technology is an interface connection structure configured to have a shape complementary to the shape of the intended wearer.

[0254] 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.

[0255] 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.

[0256] 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, replaced, combined, separated, and designed in a variety of different configurations, all of which are contemplated in this disclosure.

[0257] Immersive technology

[0258] 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.

[0259] 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.

[0260] 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 obscured or otherwise occluded). In other forms, at least a portion of the user's physical environment remains visually observable.

[0261] 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.

[0262] 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.

[0263] 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, but far enough away to avoid discomfort. Additionally, the electronic 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 (e.g., particularly relative to their eyes) over their head, 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] Virtual Reality Display System

[0268] like Figure 4A and Figure 4BAs 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.

[0269] 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.

[0270] Head-mounted display unit

[0271] 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.

[0272] 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.

[0273] Display screen

[0274] 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 housing 1205). The display screen may include electrical components that provide observable output to the user.

[0275] 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.

[0276] 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.

[0277] Monitor housing

[0278] 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.

[0279] According to this technology, some forms of display unit housing 1205 may be made of rigid, stiff or semi-rigid materials (such as plastic).

[0280] In some forms, rigid or semi-rigid materials may be at least partially covered with soft and / or flexible materials (e.g., fabrics, 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.

[0281] Other forms of display unit housing 1205 according to this technology may be made of soft, flexible, elastic materials (such as silicone rubber).

[0282] Interface connection structure

[0283] 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.

[0284] In some configurations, the interface connection structure 1100 is attached to the surface of the display unit housing 1205.

[0285] 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.

[0286] In some forms, the interface connection structure 1100 according to this technology may be made of biocompatible materials.

[0287] In some forms, the interface connection structure 1100 according to the present technology may be made of soft, flexible and / or elastic materials.

[0288] In some forms, the interface connection structure 1100 according to this technology may be made of silicone rubber and / or foam.

[0289] 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.

[0290] 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.

[0291] 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.

[0292] 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.

[0293] Sunshade

[0294] 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.

[0295] Sealing Formation Structure

[0296] like Figure 4D As shown, in one form of this technology, the interface connection structure 1100 acts as a sealing forming structure and provides a target sealing forming area. This target sealing forming area is the region on the sealing forming structure where sealing may occur. The actual sealing area—the actual sealing surface—can vary over time and depending on the user within a given session, depending on a range of factors, including but not limited to the position of the display unit housing 1205 on the face, tension in the positioning and stabilization structure 1300, and / or the shape of the user's face.

[0297] In one embodiment, the target sealing formation area is located on the outer surface of the interface connection structure 1100.

[0298] In some forms, the sunshade can form a sealed structure and press against the user's face for a seal.

[0299] In some forms, the entire periphery of the light shield or interface connection structure 1100 can be sealed against the user's skin and can block ambient light from reaching the eye area. The eye area can be formed on the area of ​​the craniotomy muscle, the user's sphenoid bone, the outer cheek area across the sphenoid bone to the left or right zygomatic arch, above the zygomatic arch, across the inner cheek area from the zygomatic arch toward the pterygoid ridge, and on the nasal ridge below the user's nose bridge point, to surround a portion of the user's face.

[0300] When acting as a sealing structure, the light shield or interface connection structure 1100 can contact sensitive areas of the user's face, such as the bridge of the nose. This contact can completely prevent ambient light from entering. Sealing the entire periphery of the display unit housing 1205 can improve the performance of the head-mounted display system 1000. Additionally, biocompatible materials can be selected so that direct contact with the user's bridge of the nose does not significantly reduce user comfort when wearing the head-mounted display system 1000.

[0301] In some forms of this technology, a system is provided that includes more than one interface connection structure 1100, each configured to correspond to a different range of sizes and / or shapes. For example, the system may include one type of interface connection structure 1100 suitable for large heads but not for small heads, and another type of interface connection structure suitable for small heads but not for large heads. The different interface connection structures 1100 may be removable and replaceable, allowing different users with heads of different sizes to use the same head-mounted display system 1000.

[0302] In some forms, the sealing structure can be formed on the craniotomy muscle, 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 nasal bridge point, to enclose a portion of the user's face. This defining area may be the eye area.

[0303] In some forms, this can create a seal around the user's eyes. The seal formed by the seal-forming structure or interface connection structure 1100 can form a light seal to limit ambient light from reaching the user's eyes.

[0304] Material biocompatibility

[0305] Biocompatible materials are defined as materials whose biological responses are comprehensively evaluated according to ISO 10993-1 standards, relating to their safety of use. This evaluation considers the nature and duration of expected contact with human tissues during use. In some forms of this technology, materials utilized in positioning and stabilizing structures, as well as interfacial bonding structures, can withstand at least some of the following biocompatibility tests: Cytotoxicity-elution test (MeM extract): ANSI / AAMI / ISO 10993-5; Skin sensitization: ISO 10993-10; Irritation: ISO 10993-10; Genotoxicity-bacterial mutagenicity test: ISO 10993-3; Implantation: ISO 10993-6.

[0306] Positioning and stabilizing structure

[0307] 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.

[0308] 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.

[0309] 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.

[0310] 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.

[0311] 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.

[0312] 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 fabric layer, a foam inner layer, and a fabric 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 fabric outer layer includes a loop material for engagement with a hook material portion.

[0313] 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.

[0314] 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.

[0315] 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.

[0316] 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.

[0317] 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.

[0318] 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.

[0319] 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.

[0320] 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.

[0321] Temporal connector

[0322] like Figure 4C As shown, some forms of the head-mounted display system 1000 or positioning and stabilization structure 1300 include temporal connectors 1250, each temporal connector 1250 capable of covering 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 supraaural 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.

[0323] 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.

[0324] In some forms, the temporal connector 1250 may extend in the anteroposterior direction and may be substantially parallel to the sagittal plane.

[0325] 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.

[0326] 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.

[0327] 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.).

[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, hytrel (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. Holding the temporal connector 1250 in its active 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 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.

[0335] 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 fabric sleeve permanently or removably attached to each temporal connector 1250.

[0336] In one embodiment, a fabric overlay can be molded onto at least one side of the reinforcement. In another embodiment, the reinforcement can be formed separately from the resilient component, and then a socket formed of a user contact material (e.g., Breath-O-Prene™) can be wrapped or slidably covered onto the reinforcement. In alternative embodiments, the user contact material can be provided to the reinforcement via adhesives, ultrasonic welding, stitching, hook and loop materials, and / or bolt connectors.

[0337] In some forms, the user contact material may be on both sides of the reinforcement, or alternatively, it may be only on the user contact side of the reinforcement (e.g., the user contact side) to reduce the volume and cost of the material.

[0338] In some forms, the temporal connector 1250 is made of a flexible material (e.g., fabric) that can comfortably rest against the user's skin and does not require additional layers to improve comfort.

[0339] Rear support section

[0340] 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.

[0341] In some configurations, the rear support portion 1350 may be connected to the display unit housing 1205 via the temporal connector 1250.

[0342] In some configurations, the temporal connector 1250 can be directly connected to the display unit housing 1205 and the rear support portion 1350.

[0343] 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.

[0344] 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.

[0345] In some forms, 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 back of the head). The posterior support portion 1350 may provide an upward and / or forward force to maintain contact with the back of the user's head.

[0346] In some configurations, 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.

[0347] 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.

[0348] Forehead support

[0349] 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 5B The 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.

[0350] 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.

[0351] In some forms, the forehead support 1360 may include a cushioning material (e.g., fabric, 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 user comfort.

[0352] In some configurations, the forehead support 1360 may be detachable 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).

[0353] 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.

[0354] 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.

[0355] 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.

[0356] 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.

[0357] 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 therefore 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 increasing the angle of the rear strip to make it more vertical.

[0358] Adjustable strip

[0359] 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.

[0360] 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.

[0361] 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.

[0362] 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).

[0363] 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 fabric 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 it is conceivable that additional sections of the temporal connector 1250 may also be made of flexible materials).

[0364] Top strip

[0365] In some forms, the positioning and stabilization 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.

[0366] 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.

[0367] 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.

[0368] 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.

[0369] 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.

[0370] 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.

[0371] In some versions, the top strip can cover the frontal and parietal bones of the user's head.

[0372] 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.

[0373] 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.

[0374] 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).

[0375] 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.

[0376] 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.

[0377] 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.

[0378] Augmented Reality Display Interface

[0379] 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.

[0380] 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.

[0381] Display unit

[0382] 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.

[0383] 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.

[0384] Display screen

[0385] 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.

[0386] 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.

[0387] 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).

[0388] 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.

[0389] 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.

[0390] Monitor housing

[0391] 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.

[0392] According to this technology, some forms of display unit housing 1205 may be made of rigid, stiff or semi-rigid materials (such as plastic).

[0393] In some forms, rigid or semi-rigid materials may be at least partially covered with soft and / or flexible materials (e.g., fabrics, 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.

[0394] Other forms of display unit housing 1205 according to this technology may be made of soft, flexible, elastic materials (such as silicone rubber).

[0395] In some forms, the display screen 1220 may protrude at least partially from 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).

[0396] 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.

[0397] Interface Structure

[0398] like Figure 5A and Figure 5B As shown, some forms of this technology include an interface connection structure 1100 (also referred to as "interface", "user interface", "interface structure", etc.), which is positioned and / or arranged to conform to the shape of the user's face and can provide the user with additional comfort when wearing and / or using the head-mounted display system 1000.

[0399] In some configurations, the interface connection structure 1100 is attached to the surface of the display unit housing 1205.

[0400] In some forms, the interface connection structure 1100 according to this technology may be made of biocompatible materials.

[0401] In some forms, the interface connection structure 1100 according to the present technology may be made of soft, flexible and / or elastic materials.

[0402] In some forms, the interface connection structure 1100 according to this technology may be made of silicone rubber and / or foam.

[0403] 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.

[0404] 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.

[0405] 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.

[0406] 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.

[0407] 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 hold the head-mounted display system 1000 in position, but may not apply forces that would cause significant discomfort (e.g., the nose pads may not be subjected to a backward stretching force).

[0408] Positioning and stabilizing structure

[0409] 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.

[0410] 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.

[0411] 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.

[0412] 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.

[0413] 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.

[0414] 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 fabric layer, a foam inner layer, and a fabric 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 fabric outer layer includes a loop material for engagement with a hook material portion.

[0415] 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.

[0416] 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.

[0417] 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.

[0418] 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.

[0419] 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.

[0420] 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.

[0421] 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.

[0422] 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.

[0423] Temporal connector

[0424] 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.

[0425] 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.

[0426] In some forms, the temporal connector 1250 may extend in the anteroposterior direction and may be substantially parallel to the sagittal plane.

[0427] 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.

[0428] 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).

[0429] 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.

[0430] 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).

[0431] 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).

[0432] 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. Holding the temporal connector 1250 in its active 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.

[0433] 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.

[0434] 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.

[0435] 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 fabric sleeve permanently or removably attached to each temporal connector 1250.

[0436] In one embodiment, a fabric overlay can be molded onto at least one side of the reinforcement. In another embodiment, the reinforcement can be formed separately from the resilient component, and then a socket formed of a user contact material (e.g., Breath-O-Prene™) can be wrapped or slidably covered onto the reinforcement. In alternative embodiments, the user contact material can be provided to the reinforcement via adhesives, ultrasonic welding, stitching, hook and loop materials, and / or bolt connectors.

[0437] In some forms, the user contact material may be on both sides of the reinforcement, or alternatively, it may be only on the user contact side of the reinforcement (e.g., the user contact side) to reduce the volume and cost of the material.

[0438] In some forms, the temporal connector 1250 is made of a flexible material (e.g., fabric) that can comfortably rest against the user's skin and does not require additional layers to improve comfort.

[0439] 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 3304 may provide a force directed outwards towards the user's head (e.g., towards the corresponding temporal bone).

[0440] Rear support section

[0441] 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.

[0442] In some configurations, the rear support portion 1350 may be connected to the display unit housing 1205 via the temporal connector 1250.

[0443] In some configurations, the temporal connector 1250 can be directly connected to the display unit housing 1205 and the rear support portion 1350.

[0444] 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.

[0445] 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.

[0446] In some forms, 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 back of the head). The posterior support portion 1350 may provide an upward and / or forward force to maintain contact with the back of the user's head.

[0447] In some configurations, 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.

[0448] 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.

[0449] Forehead support

[0450] 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.

[0451] 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.

[0452] In some forms, the forehead support 1360 may include a cushioning material (e.g., fabric, 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 user comfort.

[0453] In some configurations, the forehead support 1360 may be detachable 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).

[0454] 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.

[0455] 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.

[0456] 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.

[0457] 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.

[0458] 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 therefore 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.

[0459] Adjustable strip

[0460] 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.

[0461] 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 itself. The 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 larger length passing through the eyelet 1254 can provide a larger tensile force.

[0462] 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 the desired position. In some instances, the hook material and the loop material may be Velcro.

[0463] 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 fabric 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).

[0464] Top strip section

[0465] 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.

[0466] 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.

[0467] 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.

[0468] 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.

[0469] 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.

[0470] 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.

[0471] In some versions, the top strip can cover the frontal and parietal bones of the user's head.

[0472] 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.

[0473] 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.

[0474] 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.

[0475] 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.

[0476] 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.

[0477] Head-mounted display system with forehead support and / or back support

[0478] Figure 12 and Figure 13 A head-mounted display system 1000 is shown. Figures 7A to 11 , Figure 15 and Figures 16A to 16B A forehead support 1360 and its components suitable for the head-mounted display system 1000 are shown, and Figures 14A to 14C The rear support pad assembly 1370 is shown. The forehead support 1360 and / or the rear support pad assembly 1370 may form part of the positioning and stabilization structure 1300 for the head-mounted display system 1000. The head-mounted display system 1000 and its components disclosed herein may be constructed and arranged specifically for use in AR or VR. It should be understood that the positioning and stabilization structure 1300 and the head-mounted display system 1000, or their individual features, described herein may be applied in any of VR, MR, AR, or other artificial realities. The head-mounted display system 1000 may additionally have any of the features, configurations, aspects, functions, etc., as described elsewhere herein.

[0479] Figure 12 and Figure 13The illustrated head-mounted display system 1000 may include a head-mounted display unit 1200, which includes a display unit housing 1205. The display unit housing 1205 may include a display. In this example, the display may be as described elsewhere herein or as known in the art. Figure 12 In the example shown, the head-mounted display unit 1200 is held in front of the user's face but does not contact the user's face below the eyes. In other examples, the head-mounted display unit 1200 may include an interface connection structure 1100 connected to the display unit housing 1205 and configured and arranged to engage with the user's face surrounding the user's eyes during use.

[0480] Figure 12 and Figure 13 The positioning and stabilization structure 1300 shown is configured and arranged to hold the head-mounted display unit 1200 in an operable position on the user's head during use (e.g., such that the display is positioned in front of the user's eyes in a viewing position, and in some specific instances, such that the interface connection structure 1100 engages with the user's face to form a light seal, such as at least in the forehead, sphenoid bone, and cheek areas of the user's face).

[0481] In an example where the head-mounted display unit 1200 includes an interface connection structure 1100 that engages the user's face around the entire periphery of the user's eyes, the interface connection structure 1100 can be configured to engage the side of the user's face outside the user's eyes and the user's forehead during use. The interface connection structure 1100 can engage the user's cheeks, the side of the user's face outside the user's eyes, and the user's forehead. The interface connection structure 1100 can engage the user's face in areas covering the user's nose, maxilla, zygomatic bone, sphenoid bone, and frontal bone. For example, the interface connection structure 1100 can... Figure 4D The user's face is joined in the area shown.

[0482] exist Figure 12 In the illustrated example, the head-mounted display unit 1200 is supported in front of the user's face but does not contact the user's face. In such an example, the head-mounted display unit 1200 may be large enough in width to partially extend around the sides of the user's head to limit light leakage from the sides of the user's eyes, and may be large enough in height to limit light leakage from above and below the user's eyes. As will be described, in this example, the head-mounted display system 1000 includes a positioning and stabilizing structure 1300 with a forehead support 1360 configured to engage the user's forehead.

[0483] Forehead support

[0484] Figures 7A to 7B and Figures 8A to 8B A forehead support 1360 is shown. The forehead support 1360 can be... Figure 12 The forehead support 1360 shown is integrated into the head-mounted display system 1000. The head-mounted display system 1000 includes 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. The positioning and stabilization structure 1200 may include the forehead support 1360, such as... Figures 7A to 7B , Figures 8A to 8B , Figure 15 , Figure 16A , Figure 16B Those shown or one of the variations disclosed herein.

[0485] In some embodiments of this technology, the forehead support 1360 includes a frame 1400 (which may also be identified as a forehead frame or front frame) attached to the head-mounted display unit 1200 in use. The forehead support 1360 may also include a resilient forehead pad 1410 attached to the frame 1400. The forehead pad 1410 may be configured to engage with a user's forehead in use. In some embodiments, at least a portion of the frame 1400 is bendable in use to conform to the shape of the user's forehead. In particular embodiments, the frame 1400 may be configured to bias the forehead pad 1410 into a more curved shape than the user's forehead, such that the forehead pad 1410 conforms to the shape of the user's head in use. For example, when the forehead pad 1410 moves to engage with the user's forehead, it unfolds to conform to a particular shape of a particular user's forehead.

[0486] Specifically, such as Figure 7A and Figure 7BAs shown, the frame 1400 may include a central portion 1401 and a pair of outer portions 1402. The central portion 1401 may be designed to attach to the display unit housing 1205. The pair of outer portions 1402 have outer ends that are movable relative to the central portion 1401 to conform to the shape of a user's forehead in use. The outer portions 1402 may be designated as "wings". For example, each outer end is at least partially movable inward and outward. In some instances, each outer end of the outer portions 1402 is at least partially movable forward and backward. The distance between the outer ends of the outer portions 1402 may be less than the width of the area of ​​the forehead support 1360 intended to engage with the user's forehead, such that when the forehead pad 1410 contacts the user's head, the outer ends of the outer portions 1402 are forced to move apart a short distance while conforming to the user's forehead. The shape of the outer portions 1402 is biased to be more curved than the shape of the user's forehead, which allows the forehead support 1360 to maintain good and stable contact with the user's forehead in use. This feature also advantageously allows the forehead support 1360 to apply pressure evenly to the user's forehead during use, for example, in contrast to applying a higher level of pressure to the inner area of ​​the user's forehead that is uncomfortable compared to the outer area.

[0487] In this example, frame 1400 includes more than two parts that can bend to move relative to each other, which can advantageously allow frame 1400 to comfortably and stably conform to a wide range of user head shapes and sizes during use. Figure 9 A frame 1400 of a forehead support 1360 according to one such example of the present technology is shown. In this form, each of the outer portions 1402 includes an upper outer portion 1405 and a lower outer portion 1406, and the outer ends 1402 include an upper outer end of each upper outer portion 1405 and a lower outer end of each lower outer portion 1406. In this example, the upper outer portion 1405 is movable relative to the lower outer portion 1406, which allows the forehead support 1360 to conform to complex geometries and a wide range of forehead shapes and sizes. For example, each upper outer portion 1405 is capable of bending independently of the corresponding lower outer portion 1406 (e.g., on the same side). The upper outer ends are movable relative to the lower outer ends.

[0488] Whether the outer portion 1402 is formed by one, two, or more independently movable parts, in some instances, such as in Figure 9 In the example shown, frame 1400 may include an upper inner portion 1403 having an upper end movable relative to the center portion 1401 of frame 1400 to conform to the shape of a user's forehead in use. For example, this upper end is capable of moving at least partially forward and backward. Also... Figure 9As shown, the frame 1400 may include a lower inner portion 1404 having a lower end movable relative to the center portion 1401 of the frame 1400 to conform to the shape of a user's forehead in use. For example, this lower end is capable of moving at least partially forward and backward. Figure 9 As shown, both the upper inner portion 1403 and the lower inner portion 1404 can be located inside the outer portion 1402.

[0489] exist Figures 7A to 7B and Figures 8A to 8B In the example shown, the central portion 1401 may include a connecting portion 1407 positioned forward relative to the outer portion 1402. In some examples, the connecting portion 140 may be configured to be attached to the display unit housing 1205 of the head-mounted display unit 1200 via an intermediate component.

[0490] Rear support pad assembly

[0491] exist Figure 12 and Figure 13 In the illustrated example, the positioning and stabilization structure 1300 of the head-mounted display system 1000 includes a rear support portion 1350 and a pair of outer support portions 1330. The rear support portion 1350 is configured to engage the rear portion of the user's head during use, and the pair of outer support portions 1330 are connected between the rear support portion 1350 and the head-mounted display unit 1200 during use. The rear support portion 1350 may be part of the positioning and stabilization structure 1300 positioned at the rear of the user's head. (Reference) Figure 14A and Figure 14B The rear support portion 1350 may include a rear support pad assembly 1370, which may include a rear frame 1420 connected to the outer support portion 1330 (optionally via an intermediate member) and a rear pad 1421 connected to the rear frame 1420. The rear pad 1421 is configured to contact the user's head during use.

[0492] In use, at least a portion of the rear frame 1420 can be bent to conform to the shape of the rear surface of the user's head. For example, the rear frame 1420 can be configured to bias the rear pad 1421 into a more curved shape than the shape of the rear surface of the user's head, such that the rear pad 1421 conforms to the rear surface of the user's head in use. The flexibility and biasing in the rear frame 1420 can produce an effect at the back of the user's head similar to the effect provided by the frame 1400 of the forehead support 1360 at the user's forehead. The rear frame 1420 may include a central portion 1401 that connects in use to the outer support portion 1330 (optionally via an intermediate member).

[0493] For details, please refer to the following: Figure 14BThe rear frame 1420 may include a pair of outer portions 1402 having outer ends that are movable relative to the central portion 1401 to conform to the rear surface of a user's head in use. For example, each outer end is at least partially movable inward and outward. In some instances, each outer end of the outer portions 1402 is at least partially movable forward and backward. The distance between the outer ends of the outer portions 1402 may be less than the width of the area of ​​the rear support pad assembly 1370 intended to engage with the user's head, such that when the rear pad 1421 contacts the user's head, the outer ends of the outer portions 1402 are forced to move apart a short distance while conforming to the rear surface of the user's head. The shape of the outer portions 1402 is biased to be more curved than the shape of the rear of the user's head, which allows the rear support pad assembly 1370 to maintain good and stable contact with the rear of the user's head in use. This feature also advantageously allows the back support pad assembly 1370 to apply pressure evenly to the user's forehead during use, for example, in contrast to applying a higher level of pressure to the inner area of ​​the back surface of the user's head compared to its outer area, which is uncomfortable.

[0494] In some instances (such as) Figure 14A and Figure 14B In the example shown, the rear frame 1420 may include an upper inner portion 1403 having an upper end that is movable relative to the center portion 1401 of the rear frame 1420 to conform to the shape of the rear surface of the user's head in use. For example, this upper end is capable of moving at least partially forward and backward. Similarly... Figure 14B As shown, the rear frame 1420 may include a lower inner portion 1404 having a lower end that is movable relative to the center portion 1401 of the rear frame 1420 to conform to the rear surface of the user's head in use. For example, this lower end is capable of moving at least partially forward and backward. Figure 14B As shown, both the upper inner portion 1403 and the lower inner portion 1404 can be located inside the outer portion 1402. The flexibility of the rear frame 1420 and its composition of multiple portions that can move independently of each other can advantageously provide the same benefits as these features of the forehead support 1360, such as good conformability to a wide range of user head shapes and sizes and the ability to distribute pressure evenly.

[0495] Forehead pad material and other features

[0496] exist Figures 7A to 7B and Figures 8A to 8BIn the illustrated example, the forehead pad 1410 includes a foam layer. This foam layer can be relatively thick, for example, 8 mm, 10 mm, or in the range of 6 mm to 12 mm, and can provide elasticity to the forehead pad 1410, enabling it to conform to the surface features of the user's forehead. The frame 1400 of the forehead support 1360 can provide macroscopic adjustment of the shape of the forehead support 1360, while the forehead pad 1410 provides microscopic adjustment of the shape of the user contact surface during the conformation of the forehead support 1360 to the shape of the user's forehead. The forehead pad 1410 may include a user-contact fabric layer 1411, such as... Figures 8A to 8B As shown. The user-contact fabric layer 1411 can be attached to a silicone backing layer. The fabric layer 1411 can advantageously provide a soft feel on the user's forehead. The silicone backing layer can provide a high level of durability for the user-contact layer 1411 and can act as a barrier between the user-contact fabric layer 1411 and the foam layer, which can provide good cleanability for the user-contact fabric layer 1411 and protect the foam layer from moisture and / or other substances. The user-contact fabric layer 1411 can be attached to and supported by a silicone peripheral portion 1416 connected to and from the frame 1400. The peripheral portion 1416 can be formed of silicone or other materials, although the use of silicone provides good cleanability and it can bond well to the silicone backing layer of the user-contact fabric layer 1411.

[0497] The frame 1400 can be stiffer than the forehead pad 1410 and can be formed of a material stiffer than the material forming the forehead pad 1410, such as more rigid plastic materials, such as ABS, polycarbonate, nylon, etc., but can be designed to be flexible in the manner described above. Some parts can be constructed to be substantially rigid.

[0498] Figure 10A A forehead pad 1410 according to another embodiment of the present technology is shown. In this embodiment, the forehead pad 1410 includes a silicone layer 1411 that contacts the user. For example, the thickness of the silicone layer may be, for example, 0.75 mm, or the thickness may be between 0.5 mm and 1 mm, or the thickness may be between 0.6 mm and 0.8 mm. The forehead pad 1410 may also include as referenced above. Figure 7A The foam layer described in the example. The advantage of the user-contact silicone layer 1411 is that it can have higher cleanability / wipeability. In this example, the user-contact silicone layer 1411 includes a plurality of channels 1414 formed therein, which are configured to allow moisture to transfer between the forehead pad 1410 and the user's forehead toward the periphery of the forehead pad 1410. In some examples (such as...) Figure 10A and Figure 10BIn the example shown, channel 1414 can be configured to allow moisture to transfer toward the outer edge and / or upper edge of forehead pad 1410. Figure 10A and Figure 10B In the illustrated example, the channel 1414 is oriented to extend substantially horizontally in the sagittal plane near the user's head during use, and can be shaped to extend laterally on each side of the sagittal plane while partially curving upwards. The channel 1414 can advantageously help draw sweat outwards and upwards by capillary action, which can, for example, help prevent sweat from flowing down to the user's eyes and / or help keep the user's forehead comfortable and dry. The forehead pad 1414 can, for example, include 5 to 30 channels, 5 to 20 channels, or 10 to 15 channels. In some examples, each channel includes a diameter of 0.2 mm to 0.6 mm (e.g., 0.4 mm).

[0499] The user contact layer 1411 of the forehead pad 1410 can be attached to the frame 1400 to encapsulate the internal foam layer. The user contact layer 1411 can be permanently attached to the frame, for example, by one or more permanent clips that hold the periphery of the user contact layer 1411 to the frame 1400 at the front side of the frame. Alternatively, the user contact layer 1411 can be removably fitted to the frame. In some instances, the foam layer can be glued to the frame 1400. The frame 1400 may include one or more openings on its front side to allow air to escape during the compression of the foam layer when the user wears the head-mounted display system 1000.

[0500] The back pad 1421 can be formed of any material, layer structure, and combination thereof, which are described as options for the forehead pad 1410.

[0501] In other instances, the foam layer may be a gel layer, a silicone layer, a spacer fabric layer, or another suitable elastic cushioning material or structure.

[0502] Formed components

[0503] Figure 15 , Figure 16A and Figure 16B A forehead support 1360 according to another embodiment of the present technology is shown. In each of these embodiments, the forehead support 1360 includes a shaping member 1430 attached to a frame 1400. The shaping member 1430 is configured to impart a shape to the frame 1400. The shaping member 1430 may be more rigid than the frame and may be substantially rigid. As described above, the frame 1400 is bendable and may have portions that are bendable relative to each other. The shaping member 1430 may force the frame or portions thereof into a particular shape. The shaping member 1430 may be applied to either the forehead support 1360 or the rear support pad assembly 1370 described herein.

[0504] In some instances, the molded member 1430 is configured to be attached to the front surface of the frame 1400, such as by snap-fit ​​connection, press-fit connection with multiple lugs, magnet, or by adhesive. Figure 15 In the example shown, the formed member 1430 includes a plate. Figure 16A In the example shown, the forming member 1430 includes a skeleton. Figure 16B Another formed member 1430 in the form of a ring skeleton is shown. In other instances, the formed member 1430 may include different forms, such as a rod.

[0505] The shape of the frame 1400 can correspond to the shape of the user's forehead. In some instances, the shape of the frame 1400, as given by the shaping member 1430, corresponds to one of a series of shapes or sizes, such as small, medium, and large, or narrow and wide. In such instances, the user can select the shaping member 1430 that provides the best fit for their forehead.

[0506] In some instances, the shape of the frame imparted by the molding member 1430 matches the shape of the user's forehead. That is, the shape matches the shape of a specific, unique user. The user can scan their forehead, and the molding member 1430 can be formed based on the scan of the user's forehead. In some instances, the user can scan their entire face, and data representing the shape of the user's forehead can be extracted. In such instances, the molding member 1430 can be formed by 3D printing.

[0507] In some instances, the frame 1400 is configured, when formed by the forming member 1430, to bias the forehead pad into a more curved shape than the user's forehead, so that the forehead pad 1410 conforms to the shape of the user's head during use.

[0508] The use of the molding component 1430 can advantageously allow users to customize the forehead support 1360 or the back support pad assembly 1370 (as needed) to provide a good fit to their head. A good fit can provide a high degree of comfort and / or stability to the head-mounted display system 1000, and can provide a comfortable fit that remains throughout the extended period of use of the head-mounted display system 1000.

[0509] Figure 16B The image shows a product formed using the forming component 1430. Figure 9The frame 1400 shown is an example of a similar frame 1400. In this example, the frame 1400 includes a central portion 1401 designed to attach to the display unit housing 1205, and a pair of outer portions 1402 having outer ends movable relative to the central portion 1401. In this example, the shaping member 1430 is constructed and arranged such that the outer portions 1402 conform to the shape of the user's forehead during use. Similarly, in Figure 15 and Figure 16A In the example shown, the forming member 1430 is conformable to the outer portion 1402.

[0510] exist Figure 15 , Figure 16A and Figure 16B In all the examples shown, the outer ends of the outer portions 1402 are each at least partially movable inward and outward by the forming member 1430. The outer ends are also each at least partially movable forward and backward by the forming member 1430.

[0511] refer to Figure 16B In the example shown, each of the outer portions 1402 includes an upper outer portion 1405 and a lower outer portion 1406, and the outer ends include an upper outer end of each upper outer portion 1405 and a lower outer end of each lower outer portion 1406, each upper outer portion 1405 being bendable independently of the corresponding lower outer portion 1406 by the forming member 1430.

[0512] In this example, the frame 1400 also includes an upper inner portion 1403 having an upper end movable relative to the central portion 1401 of the frame 1400, and a shaping member 1430 is configured and arranged such that the upper inner portion 1403 conforms to the shape of the user's forehead in use. The upper end is at least partially movable forward and backward by the shaping member 1430.

[0513] Similarly, frame 1430 includes a lower inner portion 1404 having a lower end movable relative to the central portion 1401 of frame 1400, and shaping member 1430 is configured and arranged to conform the lower inner portion 1404 to the shape of a user's forehead in use. This lower end is at least partially movable forward and backward by shaping member 1430.

[0514] The central portion 1401 of the frame 1400 may include a connecting portion 1407 positioned forward relative to the outer portion 1402, the connecting portion 1407 being configured to attach to the display unit housing 1205 of the head-mounted display unit 1200, for example as... Figure 15 and Figure 16A As shown.

[0515] In some instances of this technology, the rear support pad assembly 1370 includes a forming member 1430 attached to the rear frame 1420, the forming member 1430 being configured to impart shape to the rear frame 1420. Figure 14C An example is shown.

[0516] Any features described above regarding the molding member 1430 disposed to the forehead support 1360 shall be understood to apply to the molding member 1430 when disposed to the rear support pad assembly 1370. For example, the molding member may be more rigid than the rear frame 1420. The molding member 1430 may be configured to attach to the rear surface of the rear frame 1420, for example as... Figure 14C As shown. In this example, the forming member 1430 includes a ring-shaped skeleton. The shape imparted to the rear frame 1420 by the forming member 1430 can correspond to or match the shape of the rear surface of the user's head. In some instances, the forming member 1430 is formed based on a scan of the user's head.

[0517] In some instances, the rear frame 1420, when formed by the molding member 1430, can be configured to bias the rear pad 1421 into a more curved shape than the shape of the rear surface of the user's head, so that the rear pad 1421 conforms to the rear surface of the user's head during use.

[0518] refer to Figure 14C In this example, the rear frame 1420 includes a pair of outer portions 1402 having outer ends movable relative to the central portion 1401. A shaping member 1430 is configured and arranged to conform the outer portions 1402 to the shape of the rear surface of the user's head during use. Each outer end is at least partially movable inward and outward and / or at least partially forward and backward by the shaping member 1430.

[0519] In this example, the rear frame 1420 also includes an upper inner portion 1403 having an upper end movable relative to the center portion 1401 of the rear frame 1420. A shaping member 1430 is configured and arranged to conform the upper inner portion 1403 to the shape of the rear surface of the user's head during use. This upper end is at least partially movable forward and backward by the shaping member 1430.

[0520] like Figure 14C As shown, the rear frame 1420 may include a lower inner portion 1404 having a lower end movable relative to the center portion 1401 of the rear frame 1420. A shaping member 1430 is configured and arranged to conform the lower inner portion 1404 to the shape of the rear surface of the user's head during use. The lower end is at least partially movable forward and backward by the shaping member 1430.

[0521] The recessed edge of the forehead pad

[0522] Another feature of the forehead support 1360 disclosed herein is that the forehead pad 1410 may have a recessed upper edge. (Reference) Figures 7A to 7B , Figures 8A to 8B , Figure 10A and Figure 11 The forehead pad 1410 shown, for example, includes a lower edge and an upper edge 1413, the upper edge 1413 having a superior midpoint M located in the sagittal plane of the user's head during use. In these examples, the upper edge 1413 is shaped to curve at least partially upwards away from the superior midpoint M during use. That is, the upper edge 1413 may be concave, at least when viewed from the front when worn on the user's head during use. The lower edge may include a inferior midpoint also located in the sagittal plane of the user's head during use, and the lower edge may be shaped to curve at least partially upwards away from the inferior midpoint during use. That is, the lower edge may be convex. The lower edge may include a smaller curvature in the upward direction than the upper edge 1413. As shown in the figures, the forehead pad 1410 may include a pair of circular outer edges connecting the upper and lower edges, and may be generally kidney-shaped.

[0523] This configuration (and particularly the upward-curving upper edge on the outer side of the forehead pad 1410) advantageously provides a large contact area against the user's forehead without affecting the user's hair, or with a low risk of affecting the user's hair, which could be uncomfortable. The upper edge 1413 can follow the user's hairline. This provides a uniform force distribution over a large and wide area, which can reduce peak pressure and overall pressure, thus providing good comfort and / or stability during use.

[0524] exist Figure 14A and Figure 14B In the example shown, the back pad 1421 has a raised upper edge and a raised lower edge, which can advantageously provide a large contact area between the back pad 1421 and the user's head. The back pad 1421 may be generally dome-shaped.

[0525] Top strip section

[0526] refer to Figure 14A and Figure 14BIn some embodiments of this technology, the head-mounted display system 1000 may include a top strip portion 1340 that connects between a rear support portion 1350 and a forehead support 1360 during use. The top strip portion 1340 may include a pair of front portions 1341 and rear portions 1342, with the front portion 1341 connected to the forehead support 1360 at a respective outer side. The top strip portion 1340 may be generally Y-shaped, such as… Figure 14A and Figure 14B As shown in the combination, the junction between the front portion 1341 and the rear portion 1342 can be located in the coronal plane aligned with or close to each supraacus acupoint of the user's head. The rear portion 1342 can be located in the sagittal plane during use, and the front portion 1341 can extend forward and partially laterally from the rear portion 1342 to connect to the forehead support 1362.

[0527] The front portion 1341 of the top strip 1340 can be connected to the frame 1400 of the forehead support 1360. Figure 7A In the case of the forehead support 1360 shown, the front portion 1341 of the top strip portion 1340 can be connected to the upper portion of the frame 1400, for example, as shown. Figure 12 As depicted. However, in another instance, such as Figure 11 As shown, the frame 1400 may include a pair of upper extension portions 1415 extending upward near the outer corners of the frame 1400. The front portion 1341 of the top strip portion 1340 may be connected to the corresponding upper extension portion 1415. For example, the front end of the front portion of the top strip portion 1340 may be connected to an attachment point 1417, which may be located at the end of the upper extension portion 1415, such as... Figure 11 As shown. For example, this connection can be a snap-fit, fastener, magnet, or other suitable connection. The upper extension 1415 can be configured to extend upward and partially backward and / or partially inward. The partial backward and / or inward extension of the upper extension 1415 can help push the outer and upper corners of the forehead pad 1410 into the user's forehead, which can help provide even pressure and / or good stability during use.

[0528] The rear portion 1342 of the top strap portion 1340 can be connected to the rear support portion 1350 of the positioning and stabilizing structure 1300. In an example where the rear support portion 1350 includes a rear support pad assembly 1370, the rear portion 1342 of the top strap portion 1340 can be connected to the rear support pad assembly 1370. In some specific examples, the rear portion of the top strap portion 1340 can be connected to the rear frame 1420 of the rear support pad assembly 1370. The rear portion 1342 of the top strap portion 1340 can be adjusted. For example, the rear portion 1342 can pass through an opening in the rear frame 1400 or other part connected thereto, and can be looped back and secured to itself, for example, by hook and loop connection, clip, or other suitable connection. Advantageously, unlike the front portion 1341, the rear portion 1342 of the top strap portion 1340 is adjustable, which provides the user with a single adjustment point, making the head-mounted display system 1000 easier to adjust and more user-friendly.

[0529] In other instances, the positioning and stabilizing structure 1300 may consist of only a single strip portion forming the top strip portion 1340, such as a single strip aligned with the sagittal plane of the user's head.

[0530] Figure 14A and Figure 14B Another adjustment mechanism in the example is the positioning and stabilization structure 1300, which includes a dial adjustment mechanism 1390. This dial adjustment mechanism 1390 includes a rotatable dial and is configured to change the length of the outer support portion 1330 when the dial is rotated. The dial adjustment mechanism 1390 can, for example, be located in the rear support portion 1350 and can be positioned in the sagittal plane of the user's head during use.

[0531] Self-tensioning and releasing hood

[0532] Figure 17A A head-mounted display system 1000 according to another example of the present technology is shown. Figure 17B A schematic diagram of a portion thereof is shown. Figure 17A The head-mounted display system 1000 and its positioning and stabilization structure 1300 shown can be specifically constructed and arranged for VR. However, it should be understood that the positioning and stabilization structure 1300 and the head-mounted display system 1000, or their individual features, described herein can be applied to any of VR, MR, AR, or other artificial realities. The head-mounted display system 1000 may additionally have any of the features, configurations, aspects, functions, etc., as described elsewhere herein.

[0533] Figure 17AThe illustrated head-mounted display system 1000 may include a head-mounted display unit 1200, which includes a display unit housing 1205. The display unit housing 1205 may include a display. This display may be as described elsewhere herein or as known in the art. The head-mounted display unit 1200 may include an interface connection structure 1100 connected to the display unit housing 1205 and configured and arranged to engage with a user's face in use.

[0534] Figures 17A to 17D The positioning and stabilization structure 1300 shown is configured and arranged to hold the head-mounted display unit 1200 in an operable position on the user's head during use (e.g., such that the display is positioned in front of the user's eyes at a viewing position, and such that the interface connection structure 1100 engages with the user's face to form a light seal, such as at least in the forehead, sphenoid region and cheek region of the user's face).

[0535] Interface connection structure

[0536] The interface connection structure 1100 can be configured to engage with the user's face around the periphery of the user's eyes during use. The interface connection structure 1100 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 interface connection structure 1100 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 interface connection structure 1100 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 interface connection structure 1100 can... Figure 4D The user's face is joined in the area shown.

[0537] Interface connection structure 1100 may include a face-engaging flange configured and arranged to surround the periphery of the eye region of a user's face and configured to engage the user's face in use. The face-engaging flange may be flexible and elastic, and may be in the form of a membrane. The face-engaging flange may be formed of an elastomeric material (e.g., silicone or TPE). In some instances, interface connection structure 1100 includes a pad (not visible in the figures). This pad may be at least partially covered by the face-engaging flange. The pad may be formed of foam, silicone, gel, or another suitable padding material or structure configured to serve as a pad. In some instances, interface connection structure 1100 includes a pad but does not include a face-engaging flange.

[0538] The interface connection structure 1100 can be configured to engage with the user's face and resist compression when the head-mounted display unit 1200 is securely fastened to the user's face, while maintaining user comfort. Padding (if present) can contribute to the elasticity of the interface connection structure 1100. The interface connection structure 1100 may include a pair of cheek portions configured to engage with the user's cheeks in use, a forehead portion configured to engage with the user's forehead in use, and a pair of sphenoid portions located on the respective outer sides of the interface connection structure connecting the forehead portion and the cheek portions and configured to engage with the user's head near the sphenoid bone.

[0539] In some instances, the interface connection structure 1100 includes a nose portion between cheek portions. This nose portion can be configured to engage with a user's nose in use and can be configured to at least partially block light from reaching the user's eyes from the user's nasal region (e.g., blocking light propagating via a path proximate to the surface near the user's nose). The nose portion can, for example, be configured to engage with the front, upper, and / or lateral surfaces of the user's nose in use. The nose portion can be attached to the cheek portions.

[0540] arm

[0541] Figures 17A to 17D The positioning and stabilizing structure 1300 in the illustrated example includes a pair of arms 1210 that are connected (e.g., fixedly attached or removably attached) to a respective outer side of the display unit housing 1205 during use. In this example, the arms 1210 are semi-rigid and are configured and arranged to project at least partially rearward from the display unit housing 1205 on a respective outer side of the user's head during use. Each of the arms 1210 may include a connector (e.g., a snap-fit ​​connector) for removable attachment to the display unit housing 1205.

[0542] Arm 1210 can be configured to resist bending about one or more axes and can therefore be described as reinforced or at least semi-rigid. In some instances, arm 1210 can be substantially rigid. Arm 1210 may include a fabric outer layer and may be reinforced to be substantially rigid. In some instances, arm 1210 may include a substantially rigid component covered by a fabric layer (e.g., fabric on both sides or fabric on one side). In some instances, only the user-facing side of the arm includes a fabric layer. In some instances, arm 1210 can be configured to resist bending in the upward and downward directions but allow bending inward and outward to accommodate a range of head shapes and sizes.

[0543] In some instances, each arm 1210 is at least partially covered by a fabric sleeve. In certain instances, each arm 1210 is enclosed within a fabric sleeve. Partially or completely covering the arm 1210 can provide comfortable contact between the arm 1210 and the user's head, can be aesthetically pleasing, provide a comfortable sensation, and can conceal or protect other components provided to the arm 1210 (such as electronics, sensors, transducers, etc.), or wiring extending along the arm 1210 to the rear battery pack or any other components.

[0544] strip portion

[0545] Figure 17A The positioning and stabilization structure 1300 of the illustrated head-mounted display system 1000 includes a strip portion 1380 configured and arranged to encircle the user's head in use to engage a region of the user's head that covers the frontal bone and engages the posterior region of the user's head. In some instances, the strip portion 1380 forms an occipital strip portion 1320 configured and arranged to engage the posterior region of the user's head that covers or is located below the occipital bone. In other instances, the posterior region of the user's head engaged by the strip portion 1380 may cover the parietal bone of the user's head. In use, the strip portion 1380 can fit snugly around the user's head. The strip portion 1380 engages the user's head and provides an anchor to which other portions of the head-mounted display system 1000 or its positioning and stabilization structure 1300 are connected.

[0546] exist Figures 17A to 17D In the illustrated example, the positioning and stabilization structure 1300 also includes a parietal strip portion 1310, which, together with the band portion 1380, secures the head-mounted display system 1000 to the user's head. In other examples, the positioning and stabilization structure 1300 may not include the parietal strip portion 1310, instead, the band portion 1380 may fit snugly enough to the user's head, allowing it to hold the head-mounted display system 1000 on the user's head independently. The parietal strip portion 1310 may extend between the outer portions of the band portion 1380 (e.g., between locations covering the temporal bones of the user's head). The parietal strip portion 1310 may be substantially non-stretchable or may have low stretchability to allow a close fit while providing support. The parietal strip portion 1310 may be formed of a fabric material (e.g., a tubular knitted fabric material). As previously mentioned, the spacing between the parietal strip portion 1310 and the occipital strip portion 1320 can help stabilize the positioning and structure.

[0547] The strip portion 1380 is configured to be in a tensioned state during use. The tension in the strip portion 1380 ensures that it fits snugly against the user's head, and thus helps to hold the positioning and stabilizing structure 1300 on the user's head during use.

[0548] exist Figure 17A In the illustrated example, the band-like portion 1380 includes a front portion 1380a and a rear portion 1380b. In an example where the rear portion 1380b is lower than the front portion 1380a, the rear portion 1380b may alternatively be designated as the lower portion. Similarly, in an example where the front portion 1380a is higher than the rear portion 1380b, the front portion 1380a may alternatively be designated as the upper portion. In this example, the rear portion 1380b also forms the occipital band portion 1320 of the positioning and stabilizing structure 1300.

[0549] The strip portion 1380 may include a fabric outer layer (e.g., in the form of a fabric sleeve), which may be knitted. The strip portion 1380 may also include or serve as a reinforcement. For example, the strip portion 1380 may include a reinforcing layer or a reinforcing member configured to resist deformation of the strip portion 1380. In some instances, the reinforcing layer or member may be formed of a thermoplastic elastomer (such as hyaluronic acid). The reinforcement may be inside the fabric sleeve. In one instance, the strip portion 1380 includes a fabric sleeve-shaped hyaluronic acid reinforcement. The strip portion 1380 may be partially flexible to conform to the shape of a user's head. All these options should be understood as applicable to the front portion 1380a, the rear portion 1380b, or both of the strip portion 1380. The parietal strip portion 1310 (if included) may be formed of a fabric material and may be elastic. The parietal strip portion 1310 may be attached to the strip portion 1380 by suturing, welding (e.g., ultrasonic welding), gluing, or by another suitable connection method.

[0550] In other embodiments of this technology, some or all of the portions of the positioning and stabilizing structure 1300 may comprise materials other than fabric or fabric and foam, or materials other than fabric or fabric and foam. In some embodiments, some or all of the strip portions may comprise silicone, rigid plastic, foam, leather, or another suitable material.

[0551] The strip portion 1380 may be length-adjustable and may include a dial adjustment mechanism comprising a rotatable dial. The dial adjustment mechanism can be configured to change the length of the strip portion 1380 when the dial is rotated. The dial adjustment mechanism may, for example, be located in the occipital strip portion 1320 of the strip portion 1380. In use, the dial may be positioned close to the midsagittal plane of the user's head (e.g., intersecting the sagittal plane). In an example where the positioning and stabilization structure 1300 includes a dial adjustment mechanism, the occipital strip portion 1320 / lower strip portion 1380b may be formed as two parts, a left portion and a right portion, connected by the dial adjustment mechanism, to allow adjustment of the overlap between the left and right portions when the user rotates the dial of the dial adjustment mechanism.

[0552] outer connecting part

[0553] exist Figure 17A and Figure 17B In the example shown, the head-mounted display unit 1200 is attached to the strip portion 1380 at a pair of outer connecting portions 1301. Figure 17A In this example, each of the arms 1210 is connected to the strip portion 1380 at a corresponding outer connector 1301. Each outer connector 1301 may be positioned above the user's supra-auricular base and may be aligned close to the median coronal plane aligned with each supra-auricular base of the user. Each arm 1210 may be pivotally attached to one or both of the front portion 1380a and the rear portion 1380b of the strip portion 1380.

[0554] In this example, the head-mounted display unit 1200 can be lifted upwards by the user away from the viewing position to remove the head-mounted display system 1000 from the user's head. This upward lifting movement may include the user pivoting the head-mounted display unit 1200 substantially upwards about an axis via the two outer connecting parts 1310. The upward lifting movement may then involve the user continuing to lift the head-mounted display unit 1200 upwards and / or backwards to completely remove / remove the head-mounted display system 1000 from the head. Figure 17A In the illustrated example, when the head-mounted display unit 1200 is lifted upwards away from the viewing position, the head-mounted display unit 1200 rotates at the outer connecting portion 1301, which in this example relieves tension in the strap portion 1380. This relief / reduction of tension in the strap portion 1380 facilitates the removal of the head-mounted display system 1000 from the user's head, as the strap portion 1380, when under tension, serves to hold the head-mounted display system 1000 in the proper position on the user's head. Removing this tension allows the head-mounted display system 1000 to be pulled upwards and / or backwards away from the user's head.

[0555] Conversely, when a user places the head-mounted display system 1000 on their head and lowers the head-mounted display unit 1200 to a viewing position, after the positioning and stabilizing structure 1300 is placed on top and behind the user's head, the lowering and downward pivoting movement of the head-mounted display unit 1200 around the outer connecting portion 1301 causes the strap portion 1380 to tighten, which provides a close fit to securely and comfortably hold the head-mounted display system 1000 on the user's head.

[0556] like Figure 17B , Figure 17C and Figure 17D As shown and as described above, in this example, the strip portion 1380 is formed by a front portion 1380a and a rear portion 1380b. The front portion 1380a and the rear portion 1380b each have a corresponding end at a corresponding outer connecting portion 1301. At each outer connecting portion 1301, the head-mounted display unit 1200 is connected to the corresponding end of the front portion 1380a and the rear portion 1380b. When the head-mounted display unit 1200 is in the viewing position (… Figures 17A to 17C When the head is tilted, at each outer connecting portion 1301, the corresponding ends of the front portion 1380a and the rear portion 1380b of the strip portion 1380 are pulled toward each other. This tensions the strip portion 1380 by pulling the ends of the two portions forming the strip portion 1380 together, thus facilitating a close fit to the user's head. However, when the head is tilted away from the viewing position (…), the strip portion 1380 is tilted towards each other. Figure 17D When the head-mounted display unit 1200 is lifted upwards, at each outer connecting portion, the corresponding ends of the front portion 1380a and the rear portion 1380b of the strip portion 1380 are allowed to move apart. When the ends of the two portions of the strip portion 1380 are allowed to move apart, the tension in the strip portion 1380 is released as a whole, thereby allowing the positioning and stabilizing structure 1300 to slip off the user's head or at least be pulled away more easily than in other cases.

[0557] like Figures 17B to 17D As shown, the head-mounted display unit 1200 is connected at connection point 1302 to the front portion 1380a and the rear portion 1380b of the strip portion 1380. Connection point 1302 is located between the arm 1210 and the strip portion 1380. Connection point 1302 is arranged such that the tension in the strip portion 1380 changes after the connection point 1302 is rotated.

[0558] Figure 17C and Figure 17D Positioning and stabilization structures 1300 in the viewing and release positions are shown respectively. In the viewing position of the head-mounted display unit 1200, as... Figure 17C As shown, the central axis C of each arm 1210 is aligned forward (in some instances, the central axis C may be partially aligned downward, such as...). Figure 17C As shown, and in other instances, it may be partially aligned upwards). When the head-mounted display unit 1200 is raised, or during removal, as... Figure 17D As shown, the central axis C of each arm 1210 is aligned upwards more than in the viewing position, for example, partially forward and partially upwards. In the viewing position, the central axis C of each arm 1210 may be aligned toward the user's eyes, while during release, the central axis C of each arm 1210 may be aligned toward the user's forehead, or higher on the user's forehead than in the viewing position.

[0559] When the head-mounted display unit 1200 is lifted upwards, it rotates at the outer connecting portion 1301, causing the connecting points 1302 to rotate and further space them apart along the length of the strip portion 1380. When in a position such as Figure 17C In the shown viewing position, the connection points 1302 are close together along the length of the strip portion 1380, and the two portions of the strip portion 1380 (front portion 1380a and rear portion 1380b) are spaced apart by a small gap S1. In some instances, the gap S1 may be zero or even negative (e.g., there may be overlap between the ends of the front portion 1380a and the rear portion 1380b). During release, Figure 17D As shown in the raised position, the connection point 1302 moves further apart along the length of the strip portion 1380, and the two portions of the strip portion 1380 (front portion 1380a and rear portion 1380b) are spaced apart by a distance S2 greater than the distance S1. The connection point 1302 can be forcibly moved by the arm 1210 during the lifting / pivot of the head-mounted display unit 1200, but it can also be forced apart by tension in the strip portion 1380.

[0560] like Figures 17B to 17D As shown and as described above, each arm 1210 is connected to the front portion 1380a and rear portion 1380b of the strip portion 1380 at a corresponding connection point 1302 between the arm 1210 and the front portion 1380a and rear portion 1380b of the strip portion 1380. Each connection point 1302 may be a rotatable connection point. For example, each connection point 1302 may be a pin connection. A pin may be provided to the arm 1210, and a hole (e.g., a rigid eyelet) for rotatably receiving the pin may be provided to the strip portion 1380. Similarly, as... Figure 17C and Figure 17DAs shown, the connection point 1302 on the front portion 1380a of the strip portion 1380 is positioned near the lower edge of the front portion 1380a. The connection point 1302 on the rear portion 1380b of the strip portion 1380 is positioned near the upper edge of the rear portion 1380b. Figure 17C and Figure 17D As illustrated, the connection point 1302 positioned in this manner allows the head-mounted display unit 1200 to be in a position where... Figure 17C When viewed in the position shown, the connection points are closer together along the length of the strip portion 1380 (as when the head-mounted display unit 1200 is in such a position). Figure 17D Compared to the position shown in the diagram (when raised). In particular, in Figure 17C The viewing position shown indicates that the path of connection point 1302 relative to the strip portion 1380 is more significant than their positions on the same path. Figure 17D The elevation position shown is aligned at a larger angle.

[0561] Figure 18A , Figure 18B and Figure 19 A positioning and stabilizing structure 1300 according to another embodiment of the present technology is shown. In these embodiments, each positioning and stabilizing structure 1300 includes a cam mechanism 1385 that tensions the strip portion 1380 when the head-mounted display unit 1200 is moved to a viewing position and releases the tension in the strip portion 1380 when the head-mounted display unit 1200 is lifted upward away from the viewing position. In these embodiments, the positioning and stabilizing structure 1300 includes a cam mechanism on each outer side of the positioning and stabilizing structure 1300. In other embodiments, a single cam mechanism may be provided on one outer side, configured to tension the entire strip portion 1380.

[0562] In some instances, such as Figure 18A , Figure 18B and Figure 19 In the examples shown, the cam mechanism 1385 includes a cam 1381, and one of the arms 1210 rotates the cam 1381 to operate the cam mechanism 1385 during movement of the head-mounted display unit 1200 toward or away from the viewing position. In various examples, the cam 1381 may be attached to or integrally formed with the arm 1210, or may be engaged by the arm 1210.

[0563] In some instances, the cam mechanism 1385 or its cam 1381 is configured and arranged to resist movement of the head-mounted display unit 1200 away from the viewing position when the head-mounted display unit 1200 is in the viewing position. This allows the viewing position to be stabilized compared to an arrangement in which tension in the strip portion 1380 continuously causes the head-mounted display unit 1200 to move away from the viewing position. When the user lifts the head-mounted display unit 1200 away from the viewing position, the cam mechanism 1385 can resist the movement of the head-mounted display unit 1200 away from the viewing position by initially increasing the tension in the strip portion 1380. After the initial increase in tension, the cam mechanism 1385 relieves the tension in the strip portion 1380 to allow the head-mounted display system 1000 to be removed.

[0564] The cam mechanism 1385 is operable to impart or allow relative movement of the respective ends of the front portion 1380a and the rear portion 1380b of the strip portion 1380. In some instances, the cam mechanism 1385 includes a cam 1381 and a cord 1382 that connects one of the front portion 1380a and the rear portion 1380b of the strip portion 1380 to the cam 1381. Rotation of the cam 1381 during movement of the head-mounted display unit 1200 toward a viewing position pulls the respective front portion 1380a or the rear portion 1380b toward the cam 1381 to increase tension in the strip portion 1380.

[0565] exist Figure 18A and Figure 18B In the example shown, the cam mechanism 1385 includes a cam 1381 connected to each arm 1210 of the positioning and stabilizing structure 1300. The cam 1381 may be in the form of a wheel, but may not be circular. In this example, the front portion 1380a of the strip portion 1380 is rotatably connected to the arm 1210 and / or the cam 1381. A tether 1382 connects the rear portion 1380b of the strip portion 1380 to the cam 1381. Figure 18A As shown, arm 1210 is positioned corresponding to the viewing position of the head-mounted display unit 1200 in use, and rotating cam 1381 pulls the end of the rear portion 1380b of the strip portion 1380 towards the front portion 1380a via tether 1382, thereby generating tension in the strip portion 1380. Figure 18B As shown, arm 120 is in a position corresponding to the raised position of head-mounted display unit 1200 (such as during the removal / removal of head-mounted display system 1000), and cam 1381 is in relation to it. Figure 18A The position in the middle is rotated clockwise, which releases the tension in the strip portion 1380. For example... Figure 18A and Figure 18B The comparison of two positions of arm 1210 in the figure is shown. Figure 18A The distance S1 between the corresponding ends of the front portion 1380a and the rear portion 1380b is less than Figure 18B The distance S2 between the corresponding ends in the middle.

[0566] Figure 19 Another example of a positioning and stabilizing structure 1300 including a cam mechanism 1385 is shown. In this example, the cam mechanism 1385 includes a cam 1381 and a tether 1382 that connects a front portion 1380a of a strip portion 1380 to a rear portion 1380b of the strip portion 1380. In this example, the cam 1381 is configured and arranged to engage the tether 1382 to pull the front portion 1380a and the rear portion 1380b of the strip portion 1380 together during movement of the head-mounted display unit 1200 toward a viewing position. In this example, the cam is in the form of an arm or lever.

[0567] In some instances, the tether is made of a resiliently stretchable material. In other instances, the tether is non-resilient. In some instances, the tether is non-resilient, but the strip portion 1380 or a portion thereof (such as one or both of the front portion 1380a and the rear portion 1380b) is resiliently stretchable. A portion of the resiliently stretchable strip portion 1380 or the tether 1382 allows the strip portion 1380 to fit snugly, comfortably, and stably against the user's head during use.

[0568] clean

[0569] 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.

[0570] 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.

[0571] 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.

[0572] 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.

[0573] In some instances, the cover (e.g., made of fabric, silicone, etc.) can be removably positioned over the interface connection structure and can be removed after each use for cleaning and / or replacement. This cover allows the interface structure 3400 to remain fixed to the display unit housing 1205 and provides a surface that can be easily cleaned after use.

[0574] external computer

[0575] 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.

[0576] 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).

[0577] Glossary

[0578] To achieve the purposes of this technical disclosure, one or more of the following definitions may be applied in certain forms of this technology. Alternative definitions may be applied in other forms of this technology.

[0579] General Concepts

[0580] Surrounding environmentIn some forms of this technology, the term "surrounding environment" is considered to refer to (i) outside the display interface and / or the user, and (ii) closely surrounding the display interface and / or the user.

[0581] 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.

[0582] 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.

[0583] 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.

[0584] 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.

[0585] user A person who operates the display interface and / or views the images provided by the display interface. For example, the person may wear, put on, and / or take off the display interface.

[0586] Material

[0587] Silicone resin or silicone elastomer A synthetic rubber. In this specification, reference to silicone resin refers to liquid silicone rubber (LSR) or compression-molded silicone rubber (CMSR). One commercially available form of LSR is SILASTIC, manufactured by Dow Corning (within the scope of products sold under that trademark). Another manufacturer of LSR is Wacker. Unless otherwise specified, exemplary forms of LSR have a Shore A (or Type A) indentation hardness in the range of about 35 to about 45, as measured using ASTM D2240.

[0588] polycarbonate : A thermoplastic polymer of bisphenol A carbonate.

[0589] Mechanical properties

[0590] Resilience The ability of a material to absorb energy when it is elastically deformed and to release energy after it is unloaded.

[0591] elasticity During unloading, virtually all of the energy is released. This includes, for example, certain silicones and thermoplastic elastomers.

[0592] hardness The material's inherent resistance to deformation (e.g., by Young's modulus or by indentation measured on a standardized sample size). hardness (Described using a scale).

[0593] "Soft" materials can include silicone resins or thermoplastic elastomers (TPEs) and can be easily deformed, for example, under finger pressure.

[0594] "Hard" materials can include polycarbonate, polypropylene, steel or aluminum, and can be resistant to deformation, for example, under finger pressure.

[0595] The hardness (or stiffness) of a structure or component. Stiffness is the ability of a structure or component to resist deformation in response to an applied load. This load can be a force or moment, such as compression, tension, bending, or torsion. The structure or component can provide different resistance in different directions. The antonym of stiffness is... Flexible .

[0596] Soft structures or components: Structures or components that will change shape (e.g., bend) when made to support their own weight for a relatively short period of time, such as 1 second.

[0597] Rigid structures or components A structure or component that will not substantially change shape when subjected to the loads typically encountered during use. An example of this use could be establishing and maintaining a user interface with a sealed relationship.

[0598] For example, an I-beam may have a different bending stiffness (resistance to bending loads) in the first direction compared to the second orthogonal direction. In another instance, a structure or component may be flexible in the first direction and rigid in the second direction.

[0651] The shape of the structure

[0652] 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.

[0653] 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 illustrations p The 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.

[0654] One-dimensional curvature

[0655] 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).

[0656] 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 3BCompared 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.

[0657] 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 .

[0658] 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.

[0659] Curvature of a two-dimensional surface

[0660] 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 3E A planar curve in a plane can be an instance of multiple cross-sections at a specific point.

[0661] 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 in 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.

[0662] Surface area: A set of connecting points on a surface. These points within a region may have similar characteristics, such as curvature or sign.

[0663] 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).

[0664] 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").

[0665] 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.

[0666] Planar area: Two of the surface regions have zero principal curvature (or, for example, zero within manufacturing tolerances).

[0667] Surface edge: The boundary or limit of a surface or area.

[0668] 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. (The path of an imagined person is the place where they walk on the surface, and is similar to a garden path).

[0669] 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).

[0670] 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 distances that are "in a straight line".)

[0671] hole

[0672] 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.

[0673] 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.
