Background Art

[0005] It should be understood that if any prior art is referred to herein, this reference does not constitute an admission that the prior art forms part of the common general knowledge in the art in Australia or any other country.

[0006] Immersive Technology

[0007] Immersive technology refers to technology that attempts to reproduce or enhance the physical environment by creating surrounding sensory perceptions through digital or virtual environments, thereby creating a sense of immersion.

[0008] Specifically, immersive technology provides visual immersion for users and creates virtual objects and / or virtual environments. Immersive technology can also provide immersion for at least one of the other five senses.

[0009] Virtual Reality

[0010] Virtual reality (VR) is a computer-generated three-dimensional image or environment presented to a user. In other words, the environment may be completely virtual. Specifically, the user observes an electronic screen to observe virtual or computer-generated images in a virtual environment. Because the created environment is completely virtual, the user may be blocked and / or hindered from interacting with their physical environment (e.g., they may not be able to hear and / or see physical objects in the physical environment they are currently in).

[0011] The electronic screen can be supported within the user's line of sight (e.g., mounted on the user's head). When observing the electronic screen, the visual feedback output by the electronic screen and observed by the user can produce a virtual environment intended to simulate the actual environment. For example, the user is able to look around (e.g., 360°) by turning his head or his entire body, and interact with virtual objects observable by the user through the electronic screen. This can provide an immersive experience to the user, in which the virtual environment provides stimulation to at least one of the user's five senses and replaces the corresponding stimulation of the physical environment when the user uses the VR device. Typically, the stimulation is at least related to the user's vision (i.e., because they are watching the electronic screen), but other senses may also be included. Electronic screens are typically mounted on the user's head so that they can be positioned near the user's eyes, allowing the user to easily observe the virtual environment.

[0012] In addition to visual feedback, VR devices can also generate other forms of feedback. For example, a VR device can include and / or be connected to a speaker to provide auditory feedback. VR devices can also include tactile feedback (e.g., in the form of tactile responses), which can correspond to visual and / or auditory feedback. This can create a more immersive virtual environment because the user will receive stimulation corresponding to multiple senses of the user.

[0013] When using a VR device, a user may wish to limit blocking of environmental stimuli. For example, a user may wish to avoid seeing and / or hearing the surrounding environment in order to better process the stimuli from the VR device in a virtual environment. Therefore, the VR device 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 can be arranged to be close to (e.g., in contact or close contact with) the user's face, but may not be sealed against the user's face. In either instance, ambient light may not reach the user's eyes, so that the only light that the user can observe comes from the electronic screen.

[0014] In other examples, the VR device can limit and / or prevent the user's ears from hearing ambient noise. In some examples, 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 user from hearing noise from their physical environment. In some examples, the VR device can output sound at a volume sufficient to limit the user from hearing ambient noise.

[0015] In any instance, the user may not want to be overstimulated (e.g., stimulated by both their physical environment and the virtual environment at the same time). Therefore, blocking and / or limiting the stimulation of the surrounding environment to the user helps the user focus on the virtual environment without being distracted by the surrounding environment.

[0016] Different types of VR devices are described below. Often, a single VR device may include at least two different classifications. For example, a VR device may be classified based on its portability and how the display unit connects to the rest of the interface. These classifications may be independent, so that classification in one group (e.g., portability of the unit) does not predetermine classification in another group. There may also be additional categories to classify VR devices that are not explicitly listed below.

[0017] Portability

[0018] Fixed unit

[0019] In some forms, a VR device may be used in conjunction with a separate device, such as a computer or video game console. This type of VR device may be stationary, in that it cannot be used without the computer or video game console, and therefore the locations where it can be used are limited (e.g., by the location of the computer or video game console).

[0020] Portable Unit

[0021] In some forms, the VR device may be a stand-alone unit that includes a power source and sensors so that the VR device does not need to be connected to a computer or video game console. This provides the user with more freedom of use and movement. For example, the user is not limited to using the VR device near a computer or video game console, but may use the VR device outdoors or in other environments that do not include a computer or television.

[0022] Since VR devices are not connected to a computer or video game console when in use, VR devices are required to support all necessary electronic components. This includes batteries, sensors, and processors. These components add weight to the VR device, which the user must support on their body. Proper weight distribution may be required so that this added weight does not increase discomfort for the user wearing the VR device.

[0023] In some forms, the electrical components of the VR device are contained in a single housing that can be placed directly in front of the user's face when in use. This configuration can be called a "brick". In this configuration, the center of gravity of the VR device without a positioning and stabilizing structure is directly in front of the user's face. In order to counter the moment generated by gravity, the positioning and stabilizing structure coupled to the brick configuration must provide a force directed to the user's face, such as the force generated by the tension in the headgear strap. Although the brick configuration may be beneficial for manufacturing (e.g., because all electrical components are very close) and the interchangeability of the positioning and stabilizing structures can be achieved (e.g., because they do not include electrical connections), the forces required to maintain the position of the VR device (e.g., tensile forces in the headgear) may be uncomfortable for the user. Specifically, the VR device may dig into the user's face, causing irritation and marks on the user's skin. When the user's head is subjected to the force of the display housing from the face and the force of the headgear from the back of the head, the combination of these two forces may produce a "clamping" feeling. This may make the user less likely to wear the VR device.

[0024] Because VR and other mixed reality devices can be used in ways that involve vigorous movement of the user's head and / or their entire body (e.g., during gaming), there may be significant forces / torques that tend to disturb the position of the device on the user's head. Simply making the device fit more tightly against the user's head to withstand large breaking forces may be unacceptable because it may be uncomfortable for the user or may become uncomfortable after a short period of time.

[0025] In some forms, electrical components may be spaced throughout the VR device, rather than being located entirely in front of the user's face. For example, some electrical components (e.g., batteries) may be disposed on a positioning and stabilizing structure, particularly on a rear contact portion. In this way, the weight of the battery (or other electrical component) may generate a torque that is directed in a direction opposite to the torque generated by the rest of the VR device (e.g., the display). As a result, it may be sufficient for the positioning and stabilizing structure to apply only a smaller clamping force, which in turn may result in less force on the user's face (e.g., less marking on their skin). However, in some such existing devices, cleaning and / or replacing the positioning and stabilizing structure may be more difficult due to the electrical connections.

[0026] In some forms, spacing out the electrical components may include positioning some electrical components separate from the rest of the VR device. For example, a battery and / or processor may be electrically connected but carried separately from the rest of the VR device. Unlike the "fixed unit" described above, the battery and / or processor along with the rest of the VR device may be portable. For example, the battery and / or processor may be carried on a user's belt or in a user's pocket. This may provide the benefit of reducing the weight on the user's head, but will not provide an offsetting moment. Since the total weight supported by the head is less, the tensile force provided by the positioning and stabilizing structure may still be less than a "brick" configuration.

[0027] Display Connection

[0028] Integrated display

[0029] In some forms, the display screen is an integral part of the VR device and generally cannot be separated or removed from the rest of the VR device.

[0030] The display can be fixed within the housing and protected from damage. For example, the display can be completely covered by the housing, which can reduce the occurrence of scratches. In addition, integrating the display with the rest of the VR device can avoid the situation where the display is lost.

[0031] In these forms, the display screen is used purely as an immersive technology display. The vast majority of "fixed units" will include an integrated display screen. "Portable units" may include an integrated display screen, or may include a detachable display screen (as described below).

[0032] Detachable display

[0033] In some forms, the display screen is a separate structure that can be removed from the VR device and used separately.

[0034] In some forms, a portable electronic device (e.g., a cell phone) can be selectively inserted into the housing of the VR device. The portable electronic device can include most or all sensors and / or processors, and can create a virtual environment through a downloadable application.

[0035] Portable electronic devices are generally lightweight and may not require positioning and stabilizing structures to apply significant forces to the user's head.

[0036] Augmented Reality

[0037] In some forms, augmented reality (AR) is a computer-generated three-dimensional image or environment presented to a user.

[0038] Although similar to VR, AR differs in that the virtual environment created at least in part by an electronic screen is viewed in conjunction with the user's physical environment. In other words, AR creates virtual objects in order to alter and / or augment the user's physical environment with elements of the virtual environment. The result of AR is a combined environment that includes both physical and virtual objects, and is therefore both physical and virtual.

[0039] For example, an image created by an electronic screen may be overlaid onto the user's physical environment. Only a portion of the AR composite environment presented to the user is virtual. Therefore, the user may wish to continue to receive environmental stimuli from his or her physical environment while using the AR device (e.g., in order to continue to observe physical or non-virtual components of the composite environment).

[0040] Because AR can be used with the user's physical environment, the AR device may not be electrically connected or otherwise tethered to a computer or video game console. Instead, the AR device may include a battery or other power source. This can provide the user with maximum freedom of movement, allowing them to explore a variety of physical environments while using the AR device.

[0041] This key difference between VR and AR may lead to different types of wearable electronic screens. As mentioned above, users of VR devices may want to block ambient light, so the housing of the electronic screen may be opaque in order to limit or prevent ambient light from reaching the user. However, users of AR devices may want to see the virtual environment merged with their actual environment. The electronic screen in the AR device can be similarly supported in front of the user's eyes, but the screen in the AR device can be transparent or translucent, and the screen may not be supported by an opaque housing (or the opaque material may not substantially block the user's line of sight). This can allow the user to continue to receive ambient stimulation while the virtual environment is present. Nevertheless, some VR devices without transparent screens can be configured for AR by acquiring a real-time video of the user's real-world environment from the user's perspective (e.g., using a camera on the display housing) and displaying it on a display screen, and the user can see their real-world environment through the transparent screen.

[0042] Additionally, a person using an AR device may be more mobile than a person using a VR device (e.g., because an AR user can see their physical environment and / or is not tethered to a computer or video game console). Thus, a person using an AR device may wish to wear the device for extended periods of time while also moving around (e.g., walking, running, biking, etc.). Including components such as a battery on an AR device may make the AR device uncomfortable for the user's head and / or neck, and may discourage the user from wearing the AR device for extended periods of time.

[0043] Mixed Reality

[0044] Mixed reality (MR) is similar to AR, but may be more immersive because MR devices may provide users with more ways to interact with virtual objects or environments than AR devices. Virtual reality in MR may also overlap and / or blend with the user's physical environment. However, unlike AR, the user may be able to interact with the virtual environment, similar to what happens in VR. In other words, while AR may present only computer-generated images in a physical environment, MR may present the same or similar computer-generated images to the user, but allow interaction with the images in the physical environment (e.g., using hands to "grab" virtually generated objects). Therefore, the virtual environment may be further merged with the physical environment so that the merged environment better reproduces the actual environment.

[0045] Head-mounted display interface

[0046] Head-mounted display interfaces enable users to have an immersive experience of a virtual environment and have a wide range of applications in fields such as communications, training, medical and surgical practice, engineering, and video games.

[0047] Different head-mounted display interfaces can each provide different degrees of immersion. For example, some head-mounted display interfaces can provide a fully immersive experience to the user. An example of a fully immersive experience is virtual reality (VR). A head-mounted display interface can also provide partial immersion consistent with using an AR device.

[0048] VR head-mounted display interfaces are typically provided as a system including a display unit that is arranged to be maintained in an operating position in front of a user's face. The display unit typically includes a housing containing a display and a user interface structure that is constructed and arranged to be in relative relationship 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. The user interface connection structure may engage with the face and include padding for user comfort and / or have a light seal to block ambient light from the display. The head-mounted display system also includes a positioning and stabilization structure that is disposed on the user's head to hold the display unit in place.

[0049] Other head mounted display interfaces can provide a partially immersive experience. In other words, the user 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).

[0050] AR and / or MR head-mounted display interfaces are also typically provided as a system including a display unit that is arranged to remain in an operating position in front of the user's face. Similarly, the display unit typically includes a housing containing a display and a user interface structure that is constructed and arranged to be in relative relationship to the user's face. The head-mounted display system of the AR and / or MR head-mounted display is also similar to VR in that it also includes a positioning and stabilization structure that is disposed on the user's head to hold the display unit in place. However, the AR and / or MR head-mounted display does not include a pad that completely seals ambient light from the display because these incompletely immersive experiences require elements of the physical environment. In contrast, augmented and / or hybrid head-mounted displays allow the user to see a combination of the physical environment and the virtual environment.

[0051] In any type of immersive technology, the comfort of the head mounted display interface is very important in order to allow the user to wear the head mounted display for a long period of time. In addition, it is important that the display is able to provide a changing image as the position and / or orientation of the user's head changes in order to create an environment that resembles or reproduces a fully physical environment, whether partially virtual or fully virtual.

[0052] Interface connection structure

[0053] The head mounted display may include a user interface connection structure. Since the interface connection part is in direct contact with the user's face, the shape and configuration of the interface connection part may have a direct impact on the effect and comfort of the display unit.

[0054] The design of user interface connection structures faces 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 is composed of bones, cartilage, and soft tissue, different areas of the face respond differently to mechanical forces.

[0055] One type of interfacing structure extends around the perimeter of the display unit and is intended to seal against the user's face when force is applied to the user interface, with the interfacing structure engaging the user's face. The interfacing structure may include a pad made of polyurethane (PU). With this type of interfacing structure, there may be a gap between the interfacing structure and the face, and therefore additional force may be required to force the display unit against the face to achieve the desired contact.

[0056] Areas where the user interface does not engage at all can allow gaps to form between the facial interface and the user's face, through which unwanted light contamination may enter the display unit (e.g., particularly when using virtual reality). Light contamination or "light leakage" may reduce the effectiveness and enjoyment of the user's fully immersive experience. Additionally, previous systems may be difficult to adjust so that they can be applied to a wide variety of head sizes. Furthermore, the display unit and associated stabilizing structures are typically relatively heavy and can be difficult to clean, which can further limit the comfort and usability of the system.

[0057] Another type of interfacing structure includes a sheet seal of thin material positioned around a portion of the perimeter of the display unit to provide a seal against the user's face. Similar to the previous types of interfacing structures, if the fit between the face and the interfacing structure is poor, additional force may be required to achieve a seal, or light may leak into the display unit during use. Additionally, if the shape of the interfacing structure does not match the shape of the user, the interfacing structure may wrinkle or buckle during use, resulting in undesirable light penetration.

[0058] The user interface may be characterized in part according to the design intent of the interfacing structure to engage the face during use. Some interfacing structures may be limited to engagement with areas of the user's face that protrude beyond the arc of curvature of the face-engaging surface of the interfacing 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 interfacing structure at all, or may be engaged only in a negligible manner, which may not be sufficient to increase the translational distance of the clamping pressure. These areas may typically include both sides of the user's face, or areas near and around the user's nose. To the extent that there is a mismatch between the shape of the user's face and the interfacing structure, it is advantageous that the interfacing structure or related components are adaptable so as to form an appropriate contact or other relationship.

[0059] Positioning and stabilization

[0060] In order to keep the display unit in its correct operating position, the head-mounted display system also includes positioning and stabilizing structures disposed on the user's head. These structures may be responsible for providing forces to counteract the gravity of the head-mounted display and / or the interface connection structure. In the past, these structures were formed of retractable rigid structures that were typically applied to the head under tension to keep the display unit in its operating position. Such systems tend to apply clamping pressure on the user's face, which may cause discomfort to the user at local stress points. Moreover, previous systems may be difficult to adjust to allow for a wide range of head size applications. In addition, the display unit and associated stabilizing structures are typically heavy and difficult to clean, further limiting the comfort and usability of the system.

[0061] Certain other head mounted display systems may not be functionally suitable for use in this field. For example, positioning and stabilization structures designed for decorative and visual aesthetics may not have the structural ability to maintain appropriate pressure around the face. For example, excessive clamping pressure may cause discomfort to the user, or alternatively, insufficient clamping pressure on the user's face may not effectively seal the display from ambient light.

[0062] Some other head mounted display systems may be uncomfortable or impractical for the present technology, for example if the system is used for an extended period of time.

[0063] Due to these challenges, some head-mounted displays suffer from one or more of the following issues: obtrusive, unsightly, expensive, poorly fitting, difficult to use, and uncomfortable, especially when worn for extended periods of time or when the user is unfamiliar with the system. The wrong size positioning and stabilization structures can reduce comfort and, in turn, shorten usage time.

[0064] Thus, the interfacing portions of a user interface for a fully immersive experience of a virtual environment are subject to forces corresponding to the movements of the user during the experience.

[0065] Material

[0066] Materials used in head mounted display components include dense foam for parts in the contact interface connection structure, rigid shells for the outer shell, and positioning and stabilization structures formed by rigid plastic clamping structures. These materials have various disadvantages, including not allowing the skin covered by the materials to breathe, lack of elasticity, difficulty in cleaning, and easy breeding of bacteria. As a result, products made with such materials can be uncomfortable when worn for long periods of time, causing skin irritation in some individuals and limiting the application of the products.

[0334] Before describing the present technology in more detail, it should be understood that the technology is not limited to the specific examples described herein, which may vary. It should also be understood that the terminology used in the present disclosure is only for the purpose of describing the specific examples discussed herein and is not intended to be limiting.

[0335] The following description is provided about various examples that can share one or more common characteristics and / or features. It should be understood that one or more features of any one example can be combined with one or more features of another example or other examples. In addition, any single feature or combination of features in any one example can constitute another example.

[0336] In the following detailed description, reference is made to the accompanying drawings which form a part of the detailed description. The illustrative embodiments described in the detailed description, depicted in the accompanying 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 the disclosure as generally described herein and shown in the accompanying drawings may be arranged, substituted, combined, separated, and designed in a variety of different configurations, all of which are contemplated in the present disclosure.

[0337] Immersive Technology

[0338] Immersive technology can present a user with a combination of a virtual environment and the user's physical environment or the real world. The user can interact with the resulting immersive or combined reality.

[0339] The device immerses the user by augmenting or replacing the stimulus associated with one of the user's five senses with a virtual stimulus. Typically, this is a virtual stimulus, although additional stimuli may be present to augment or replace the stimulus associated with one of the other four senses.

[0340] In some forms, a particular immersive technology may present a combination of a virtual environment and a user environment to a user. At least a portion of the resulting environment may include the virtual environment. In some instances, the entire resulting environment may be a virtual environment (e.g., meaning that the user's environment may be blocked from view or otherwise obscured). In other forms, at least a portion of the user's physical environment may still be visually observable.

[0341] In some forms, users may use different types of immersive technology, which may include but are not limited to virtual reality (VR), augmented reality (AR), or mixed reality (MR). Each type of immersive technology may present a different environment to the user and / or a different way to interact with the environment.

[0342] In some forms, the display system can be used with each type of immersive technology. The display screen of the display system can provide virtual environment components to the combined environment (i.e., the combination of the virtual environment and the user environment). In some forms, the display screen can be an electronic screen.

[0343] In at least some types of immersive technologies (e.g., VR, AR, MR, etc.), positioning and stabilizing electronic screens may help operate the corresponding devices. For example, users may want electronic screens to be positioned close enough to their eyes for viewing, but far enough away so as not to cause discomfort. In addition, electronic screens may need to be spaced far enough apart so that users can simultaneously wear corrective lenses, such as glasses. In addition, users can try to maintain the orientation of the electronic screen relative to their eyes. In other words, users who walk or otherwise move while using these devices may not want the devices to bounce on their heads or otherwise move (e.g., particularly relative to their eyes) because this may cause dizziness and / or discomfort to the user. Therefore, these devices can be supported against the user's head to limit the relative movement between the user's eyes and the device.

[0344] In one form, the technology includes a method for using a VR device, the method comprising supporting the device on a user's head, near at least one of the user's eyes, and within the user's line of sight.

[0345] In some examples of the present technology, a head mounted display unit is supported in front of the user's eyes so as to block, obstruct and / or limit ambient light from reaching the user's eyes.

[0346] Any features disclosed below in the context of a device configured for VR will be understood to be applicable to devices configured for AR, unless the context clearly requires otherwise. Similarly, features disclosed below in the context of a device configured for AR will be understood to be applicable to devices configured for VR, unless the context clearly requires otherwise. For the avoidance of doubt, features disclosed in the context of a device that does not have a transparent display (through which a user can view the real world) should be understood to be applicable to devices with such a transparent display, unless the context clearly requires otherwise. Similarly, features disclosed in the context of a device with a transparent display (through which the real world can be viewed) should be understood to be applicable to devices in which the display is electronic and the real world cannot be viewed directly through the transparent material.

[0347] Virtual reality display system

[0348] 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. In use, the head-mounted display unit 1200 is arranged to be positioned near and in front of the user's eyes, thereby allowing the user to view the display.

[0349] 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 to the head mounted display system 1000, while in other instances, these may be modular and incorporated into the head mounted display system 1000 as desired by the user.

[0350] Head mounted display unit

[0351] The head mounted display unit 1200 may include a structure for providing an observable output to a user. Specifically, the head mounted display unit 1200 is arranged to be maintained (eg, manually, by positioning and stabilizing structures, etc.) in an operating position in front of the user's face.

[0352] In some examples, the head mounted display unit 1200 may include a display screen 1220, a display unit housing 1205, an interfacing structure 1100, and / or an optical lens 1240. In some forms, a protective layer 1242 may be formed around at least a portion of the optical lens 1240. These components may be permanently assembled into a single head mounted display unit 1200, or they may be separable and selectively connected by a user to form the head mounted display unit 1200. In addition, the display screen 1220, the display unit housing 1205, the interfacing structure 1100, and / or the 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.

[0353] Display

[0354] Some forms of head mounted display unit 1200 include a display, such as a display screen ( Figure 4B 1204), but is disposed within the display unit housing 1205. The display screen may include electrical components that provide a viewable output to a user.

[0355] In one form of the present technology, a display screen provides an optical output observable by a user. The optical output allows the user to observe a virtual environment and / or a virtual object.

[0356] The display screen may be positioned close to the user's eyes to allow the user to view the display screen. For example, the display screen may be located in front of the user's eyes. The display screen may output computer-generated images and / or virtual environments.

[0357] Display housing

[0358] In such Figure 4A and Figure 4B In some forms of the technology shown, the display unit housing 1205 provides a support structure for the display screen so as 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 constructed of a material suitable for protecting the display screen from impact forces. The display unit housing 1205 may also contact the user's face and may be constructed of a biocompatible material suitable for limiting irritation to the user.

[0359] The display unit housing 1205 according to some forms of the present technology may be constructed from a hard, rigid or semi-rigid material such as plastic.

[0360] In some forms, the rigid or semi-rigid material may be at least partially covered with a soft and / or flexible material (e.g., fabric, silicone, etc.). This may improve biocompatibility and / or user comfort because at least a portion of the display unit housing 1205 that a user engages (e.g., grasps with their hand) includes a soft and / or flexible material.

[0361] Other forms of display unit housing 1205 according to the present technology may be made of soft, flexible, elastic materials (such as silicone rubber).

[0362] Interface connection structure

[0363] like Figure 4A and Figure 4B As shown, some forms of the present 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 increased comfort to the user when wearing and / or using the head-mounted display system 1000.

[0364] In some forms, the interfacing structure 1100 is coupled to a surface of the display unit housing 1205 .

[0365] In some forms, the interfacing structure 1100 may extend at least partially around the display unit housing 1205 and may form a viewing opening. In use, the viewing opening may at least partially accommodate the face of the user. Specifically, the user's eyes may be accommodated within the viewing opening formed by the interfacing structure 1100.

[0366] In some forms, an interfacing structure 1100 in accordance with the present technology may be constructed from biocompatible materials.

[0367] In some forms, an interfacing structure 1100 in accordance with the present technology may be comprised of a soft, flexible and / or elastic material.

[0368] In certain forms, an interfacing structure 1100 in accordance with the present technology may be constructed from silicone rubber and / or foam.

[0369] In some forms, the interface connection structure 1100 can contact sensitive areas of the user's face, which can be uncomfortable locations. The material forming the interface connection structure 1100 can cushion these sensitive areas and limit the discomfort felt by the user when wearing the head-mounted display system 1000.

[0370] In some forms, these sensitive areas may include the user's forehead. Specifically, this may include areas of the user's head near the frontal bone, such as the parietal muscles and / or the glabella. This area may be more sensitive because there is limited natural cushioning from muscle and / or fat between the user's skin and bones. Similarly, the user's nasal spine may also include little to no natural cushioning.

[0371] In some forms, the interfacing structure 1100 may comprise a single element. In some embodiments, the interfacing structure 1100 may be designed for mass production. For example, the interfacing structure 1100 may be designed to comfortably fit a wide range of different facial shapes and sizes.

[0372] In some forms, the interfacing structure 1100 may include different elements that cover different areas of the user's face. Different portions of the interfacing structure 1100 may be constructed of different materials and provide different textures and / or cushioning to the user in different areas.

[0373] Lens hood

[0374] Some forms of the head mounted display system 1000 may include a visor that may be made of an opaque material and that may block ambient light from reaching the user's eyes. The visor may be part of the interface structure 1100, or may be a separate element. In some instances, in addition to providing a comfortable contact portion for contact between the head mounted display unit 1200 and the user's face, the interface structure 1100 may also form a visor by shielding the user's eyes from ambient light. In some instances, the visor may be formed of multiple components that work together to block ambient light.

[0375] In some forms, the visor can block ambient light from reaching the eye area, and the visor can be formed on the parietal muscles, the area of ​​the user's sphenoid bone, through the sphenoid bone to the outer cheek area between the left zygomatic arch or the right zygomatic arch, on the zygomatic arch, through the inner cheek area from the zygomatic arch toward the pterygoid ridge, and on the user's nasal ridge located below the nasal bridge point to enclose a portion of the user's face therebetween.

[0376] In one form, the visor may not contact the user's face around its entire perimeter. For example, the visor may be spaced apart from the user's nasal spine. The width of the space may be substantially small so as to substantially limit the entry of ambient light. However, the user's nasal spine may be sensitive and easily irritated. Therefore, avoiding direct contact with the user's nasal spine may improve the user's comfort when wearing the head mounted display system 1000.

[0377] In some forms, the visor may be part of the display unit housing 1205 and may be integrally or detachably coupled to the display unit housing 1205. In one form, if the display unit housing 1205 is usable with a display screen that outputs AR or MR and VR, the visor may be detachable from the display unit housing 1205 and coupled to the display unit housing 1205 only when VR is used.

[0378] Positioning and stabilizing structures

[0379] like Figure 4A and Figure 4B As shown, the display screen 1220 and / or the display unit housing 1205 of the head-mounted display system 1000 of the present technology can be held in place by the positioning and stabilizing structure 1300 during use.

[0380] In order to keep the display screen 1220 and / or the display unit housing 1205 in its correct operating position, the positioning and stabilizing structure 1300 is ideally comfortable relative to the user's head so as to accommodate the load caused by the weight of the display unit in a manner that minimizes facial marks and / or pain caused by prolonged use. It is also necessary to achieve a universal fit without sacrificing comfort, usability, and manufacturing costs. Design criteria may include adjustability within a predetermined range, and a low-touch, simple setup 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 the immersive experience of the virtual environment, the user can communicate, i.e., speak, while using the head-mounted display system 1000. In this way, the user's jaw or mandible can move relative to other bones of the skull. In addition, the entire head can move during the use period of the head-mounted display system 1000. For example, movement of the user's upper body, in some cases movement of the lower body, and particularly movement of the head relative to the upper and lower bodies.

[0381] In one form, the positioning and stabilizing structure 1300 provides a retaining force to overcome the effects of gravity on the display screen 1220 and / or the display unit housing 1205 .

[0382] In one form of the present technology, a positioning and stabilizing structure 1300 is provided that is configured in a manner consistent with a comfortable fit for 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 bulk of the device. In one example, the positioning and stabilizing structure 1300 includes at least one strip having a rectangular cross-section. In one example, the positioning and stabilizing structure 1300 includes at least one flat strip.

[0383] In one form of the present technology, a positioning and stabilizing structure 1300 is provided that is configured so as not to be too bulky and cumbersome so as not to prevent a user from comfortably moving their head from side to side.

[0384] In one form of the present technology, the positioning and stabilizing structure 1300 comprises a belt comprised of a laminate of a fabric user contacting 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 belt. In one form, the skin contacting layer of the belt is formed of a material that helps wick moisture away from the user's face. In one form, the fabric outer layer comprises a loop material for engaging with a hook material portion.

[0385] In some forms of the present technology, the positioning and stabilizing structure 1300 includes an extendable strap, such as an elastically extendable strap. For example, the strap can be configured to be in tension during use and direct a force to pull the display screen 1220 and / or display unit housing 1205 toward a portion of the user's face, particularly near the user's eyes and in line with their field of vision. In one example, the strap can be configured as a tie strap.

[0386] In one form of the present technology, the positioning and stabilising structure 1300 comprises a first strap constructed and arranged such that, in use, at least a portion of its lower edge passes above the supra-auricular base of the user's head and covers a portion of the parietal bone without covering the occipital bone.

[0387] In one form of the present technology, the positioning and stabilising structure 1300 includes a second strap which is constructed 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.

[0388] In one form of the present technology, the positioning and stabilising structure 1300 includes a third strap constructed and arranged to interconnect the first strap and the second strap to reduce the tendency of the first strap and the second strap to separate from each other.

[0389] In some forms of the present technology, the positioning and stabilizing structure 1300 comprises a flexible and, for example, non-rigid band. An advantage of this aspect is that the band fits more comfortably on the user's head.

[0390] In some forms of the present technology, the positioning and stabilising structure 1300 comprises a belt that is configured to be breathable to allow moisture to pass through the belt.

[0391] In some forms of the present technology, a system is provided that includes more than one positioning and stabilizing structure 1300, each positioning and stabilizing structure configured to provide a retention force corresponding to a different range of sizes and / or shapes. For example, a system may include one form of positioning and stabilizing structure 1300 that is suitable for large sized heads but not for small sized heads, and another form of positioning and stabilizing structure that is suitable for small sized heads but not for large sized heads.

[0392] In some forms, the positioning and stabilizing structure 1300 may include a cushioning material (e.g., a foam pad) for contacting the user's skin. The cushioning material may provide additional wear resistance to the positioning and stabilizing structure 1300, particularly if the positioning and stabilizing structure 1300 is constructed of a rigid or semi-rigid material.

[0393] Temporal connector

[0394] like Figure 4CAs shown, some forms of the head mounted display system 1000 or positioning and stabilizing structure 1300 include a temporal connector 1250 or arm, each of which can cover a corresponding one of the user's temporal bones in use. A portion of the temporal connector 1250 contacts an area of ​​the user's head near the supraauricular base point (i.e., above each ear of the user) in use. In some examples, the temporal connector is a band portion of the positioning and stabilizing structure 1300. In other examples, the temporal connector is an arm of the head mounted display unit 1200. In some examples, the temporal connector of the head mounted display system 1000 can be formed in part by a band portion (e.g., outer band portion 1330) of the positioning and stabilizing structure 1300 and in part by an arm 1210 of the head mounted display unit 1200.

[0395] The temporal connectors 1250 may be outer portions of the positioning and stabilising structure 1300, as each temporal connector 1250 is located on the left or right side of the user's head.

[0396] In some forms, the temporal connector 1250 can extend in the anterior-posterior direction and can be substantially parallel to the sagittal plane.

[0397] In some forms, the temporal connectors 1250 may be coupled to the display unit housing 1205. For example, the temporal connectors 1250 may be connected to a side of the display unit housing 1205. For example, each temporal connector 1250 may be coupled to a respective one of the left side 1234 and the right side 1236 of the display unit housing.

[0398] In some forms, the temple connectors 1250 can be pivotally connected to the display unit housing 1205 and can provide relative rotation between each temple connector 1250 and the display unit housing 1205.

[0399] In some forms, the temple connector 1250 may be removably connected to the display unit housing 1205 (eg, via magnets, mechanical fasteners, hook and loop material, etc.).

[0400] In some forms, the temporal connector 1250 may be arranged, in use, to extend generally along or parallel to the Frankfurt horizontal plane of the head and above the zygomatic bone (e.g., above the cheekbone of the user).

[0401] In some forms, the temple connector 1250 may be positioned against the user's head similar to the arms of eyeglasses and positioned higher than the anti-helix of each respective ear.

[0402] In some forms, the temporal connector 1250 can have a generally elongated and flat configuration. In other words, the length and width (from top to bottom in the paper plane) of each temporal connector 1250 are much greater than the thickness (into the paper plane).

[0403] In some forms, the temporal connectors 1250 may each have a three-dimensional shape having curvature in 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 is intended to conform closely to the user's head so as to remain unobtrusive and maintain a low profile (e.g., not appear overly bulky).

[0404] In some forms, the temporal connector 1250 can be made of a rigid or semi-rigid material, which may include plastic, Hytrel (a thermoplastic polyester elastomer), or other similar materials. The rigid or semi-rigid material can be self-supporting and / or able to maintain its shape without being worn. This can make it more intuitive or obvious for the user to understand how to use the positioning and stabilizing structure 1300, and can be contrasted with a positioning and stabilizing structure 1300 that is completely soft and does not maintain its shape. Keeping the temporal connector 1250 in a use state before use can prevent or limit deformation when the user wears the positioning and stabilizing structure 1300, and allow the user to quickly assemble or wear the head-mounted display system 1000.

[0405] In some forms, the temporal connector 1250 may be a rigid member, which may allow for more efficient (eg, direct) transmission of tension through the temporal connector 1250 because the rigid member limits the extent of elongation or deformation of the arm during use.

[0406] In some forms, the temporal connector 1250 may be at least partially flexible in one direction and more rigid in another direction. The user may be able to bend or flex the temporal connector more in one direction than in another direction. For example, the temporal connector 1250 may be at least partially flexible along an axis substantially parallel to the user's sagittal plane (e.g., in the up-and-down direction when in use). This may allow the temporal connector 1250 to conform to the shape of the user's head by moving in a lateral direction toward or away from the user's head. The user may also be able to make multiple adjustments along the length of the temporal connector 1250 to correspond to various structures along the user's head. However, bending along an axis substantially parallel to the user's coronal plane (e.g., extending in the lateral direction when in use) may be more difficult. The temporal connector 1250 may resist bending in the up-and-down direction.

[0407] In some forms, the positioning and stabilizing structure 1300 can be designed so that the positioning and stabilizing structure 1300 is ready to use "out of the box" and generally into its use configuration. Additionally, the positioning and stabilizing structure 1300 can be arranged to retain its shape in use once out of the box (e.g., because a rigid member can be formed to retain the shape of some or part of the positioning and stabilizing structure 1300). Advantageously, because the positioning and stabilizing structure 1300 is generally arc-shaped, closely resembling the back 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 generally dome-shaped.

[0408] In some forms, a flexible and / or elastic material may be disposed around the rigid or semi-rigid material of the temporal connector 1250. The flexible material may fit more comfortably against the user's head to improve wear resistance and provide soft contact with the user's face. In one form, the flexible material is a fabric sleeve that is permanently or removably coupled to each temporal connector 1250.

[0409] In one form, the fabric may be overmolded onto at least one side of the rigidizer. In one form, the rigidizer may be formed separately from the elastic component and then the user contacts the material (e.g., Breath-O-Prene TM ) can be wrapped or slipped over the rigid member. In alternative forms, the user contact material can be provided to the rigid member by adhesive, ultrasonic welding, stitching, hook and loop material and / or bolt connectors.

[0410] In some forms, the user contacting material may be on both sides of the rigid member, or alternatively may be only on the user contacting side of the rigid member (eg, the user contacting side) to reduce material bulk and cost.

[0411] In some forms, the temporal connector 1250 is comprised of a flexible material (eg, fabric) that may sit comfortably against the user's skin and may not require added layers to increase comfort.

[0412] Rear support part

[0413] like Figure 4C As shown, some forms of the positioning and stabilizing structure 1300 may include a rear support portion 1350 for auxiliary support of the display screen 1220 and / or the display unit housing 1205 (eg, Figure 4B The rear support portion 1350 can help 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.

[0414] In some forms, rear support portion 1350 may be coupled to display unit housing 1205 via temple connector 1250 .

[0415] In some forms, the temple connector 1250 may be directly coupled to the display unit housing 1205 and the rear support portion 1350 .

[0416] In some forms, the rear support portion 1350 can have a three-dimensional contour curve to fit the shape of the user's head. For example, the three-dimensional shape of the rear support portion 1350 can have a generally circular three-dimensional shape that is suitable for covering a portion of the parietal and occipital bones of the user's head in use.

[0417] In certain forms, rear support portion 1350 may include upper section 1310 and lower section 1320. Upper section 1310 and lower section 1320 may be continuous and form a circular shape (eg, circular, oval, etc.) of the rear support portion.

[0418] In some forms, the rear support portion 1350 can be at least partially rigidified so that the circular shape can be maintained even when the user is not wearing it. This can help the user wear the rear support portion 1350 because the rigidity can limit tangling.

[0419] In one form, the rigidity can provide "springiness" to the rear support portion 1350. For example, the rear support portion 1350 can "bounce" after being compressed. In other words, the rear support portion 1350 can be flexible enough to be folded, but once the force is removed, the rear support portion 1350 returns to its original shape (e.g., a three-dimensional circular shape).

[0420] In some forms, the rear support portion 1350 may be a rear portion of the positioning and stabilizing structure 1300. The rear support portion 1350 may provide an anchoring force that is at least partially directed in a forward direction.

[0421] In some forms, the lower section 1320 of the rear support portion 1350 is the lowermost portion of the positioning and stabilizing structure 1300. For example, the rear support portion 1350 can contact the area of ​​the user's head between the occipital bone and the trapezius muscles. The rear support portion 1350 can hook the lower edge of the occipital bone (e.g., the back of the head). The rear support portion 1350 can provide a force directed in an upward and / or forward direction to maintain contact with the back of the user's head.

[0422] In some forms, the lower section 1320 of the rear support portion 1350 is the lowest portion of the entire head mounted display system 1000. For example, the rear support portion 1350 can be positioned at the base of the user's neck (e.g., covering the occipital bone and trapezius muscles 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.

[0423] In some forms, when in contact with the user's head, upper section 1310 can cover the parietal bones. The rounded shape of rear support portion 1350 can allow rear support portion 1350 to lie substantially flat on the user's head while lower section 1320 contacts the user's head as described above.

[0424] In some forms, the rear support portion 1350 can include padding material that can contact the user's head (e.g., covering the area between the occipital bone and the trapezius muscles). The padding material can provide additional comfort to the user and limit the marks caused by the rear support portion 1350 pulling on the user's head.

[0425] In some forms, the rear support portion 1350 can be constructed of a fabric material and / or a foam material. These materials can be biocompatible and comfortable for the user's head.

[0426] In one form, the rear support portion 1350 can be made of a foam material that is at least partially covered by a fabric material. The outer fabric material can provide a comfortable feel against the user's skin. The inner foam layer can allow the rear support portion 1350 to compress and improve comfort.

[0427] Forehead support

[0428] Some versions of the positioning and stabilising structure 1300 may include a forehead support portion or forehead support 1360 which is configured to contact the user's head above the user's eyes when in use. Figure 5B The positioning and stabilizing structure 1300 shown includes a forehead support 1360. In some examples, Figure 4A The illustrated positioning and stabilizing structure 1300 may include a forehead support 1360. The forehead support 1360 may cover the frontal bone of the user's head. In some forms, the forehead support 1360 may also be higher than the sphenoid bone and / or the temporal bone. This may also position the forehead support 1360 higher than the user's eyebrows.

[0429] In some forms, forehead support 1360 may be a front portion of positioning and stabilising structure 1300 and may be disposed more anteriorly on the user's head than any other portion of positioning and stabilising structure 1300. Rear support portion 1350 may provide a force at least partially directed in a rearward direction.

[0430] In some forms, forehead support 1360 may include a cushioning material (e.g., fabric, foam, silicone, etc.) that may contact the user and may help limit marking caused by the straps of positioning and stabilizing structure 1300. Forehead support 1360 and interfacing structure 1100 may work together to provide comfort to the user.

[0431] In some forms, forehead support 1360 may be separate from display unit housing 1205 and may contact the user's head at a different location than display unit housing 1205 (e.g., a higher position).

[0432] In some versions, forehead support 1360 may be adjustable to allow positioning and stabilizing structure 1300 to adapt to the shape and / or configuration of a user's face.

[0433] In some forms, the temporal connector 1250 may be coupled to the forehead support 1360 (eg, at a side of the forehead support 1360 ). The temporal connector 1250 may extend at least partially downwardly so as to couple to the rear support portion 1350 .

[0434] In some forms, the positioning and stabilizing structure 1300 may include multiple pairs of temporal connectors 1250. For example, a pair of temporal connectors 1250 may be coupled to the forehead support 1360, and a pair of temporal connectors 1250 may be coupled to the display unit housing 1205.

[0435] In some forms, forehead support 1360 can be presented at an angle substantially parallel to the user's forehead to provide improved comfort to the user. For example, forehead support 1360 can position the user in an orientation that covers the frontal bone and is substantially parallel to the coronal plane. Positioning the forehead support substantially parallel to the coronal plane can reduce the likelihood of pressure sores due to unevenness.

[0436] In some forms, the forehead support 1360 can be offset from the rear support or rear support portion that contacts the user's head rear area (e.g., the area covering the occipital bone and trapezius muscle). In other words, the axis along the rear band will not intersect with the forehead support 1360, and the forehead support 1360 can be arranged to be lower and more forward than the axis along the rear band. The offset generated between the forehead support 1360 and the rear band can generate a moment of force against the gravity of the display screen 1220 and / or the display unit housing 1205. A larger offset can generate a larger moment of force, and therefore is more helpful to 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., more forward and lower along the user's head), and / or increasing the angle of the rear band to make it more vertical.

[0437] In some versions, forehead support 1360 may be constructed of a compressible material that may provide support to the user during use.

[0438] In some forms, forehead support 1360 can be constructed of silicone, foam, and / or fabric. For example, fabric can be used in combination with silicone or foam, although any material can be used independently. When used together, the fabric can be the outer layer of forehead support 1360 and can contact the user's head. The foam and / or silicone can be the inner layer that compresses when forehead support 1360 is under tension on the user's head.

[0439] Adjustable strap

[0440] like Figure 4C As shown, portions of the positioning and stabilizing structure 1300 may be adjustable to apply selective tensile forces on the display screen 1220 and / or the display unit housing 1205 to secure the position of the display screen 1220 and / or the display unit housing 1205 .

[0441] In some forms, the display unit housing 1205 may include at least one ring or eyelet 1254 (e.g., Figure 4B 1254) and at least one of the temporal connectors 1250 can be passed through the loop and folded back on itself. The length of the temporal connector 1250 passed through the corresponding eyelet 1254 can be selected by the user to adjust the tension provided by the positioning and stabilizing structure 1300. For example, passing a greater length of the temporal connector 1250 through the eyelet 1254 can provide greater tension.

[0442] In some forms, at least one of the temporal connectors 1250 may include an adjustment portion 1256 and a receiving portion 1258 (eg, Figure 4C 1254 on the display unit housing 1205 and can be coupled to the receiving portion 1258 (e.g., by folding back on itself). The adjustment portion 1256 can include a hook material and the receiving portion 1258 can include a loop material (or vice versa) so that the adjustment portion 1256 can be removably retained in a desired position. In some examples, the hook material and the loop material can be Velcro.

[0443] 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 hood against the user's head (e.g., when the hood is used as a seal-forming structure).

[0444] In some forms, the adjustment portion 1256 can be constructed of a flexible and / or elastic material that can conform to the shape of the user's head and / or can allow the adjustment portion to pass through the eyelet 1254. For example, the adjustment portion 1256 can be constructed of an elastic fabric that can provide elastic stretch. The remainder of the temporal connector 1250 can be constructed of the rigid or semi-rigid materials described above (although it is contemplated that additional sections of the temporal connector 1250 can also be constructed of flexible materials).

[0445] Top band

[0446] In some forms, the positioning and stabilizing structure 1300 may include a top strap portion that covers an upper region of a user's head. Figure 1A The illustrated head mounted display system 1000 has a top strap portion.

[0447] In some forms, the top strap portion may extend between a front portion of the head mounted display system 1000 and a rear region of the head mounted display system 1000 .

[0448] In some forms, the top strap portion may be constructed of a flexible material and may be configured to conform to the shape of a user's head.

[0449] In some forms, the top strap portion may be connected to the display unit housing 1205. For example, the top strap portion may be coupled to the upper surface 1230 of the display unit housing. The top strap portion may also be coupled to the display unit housing 1205 near its rear end.

[0450] In some forms, the top strap portion can be coupled to the forehead support 1360. For example, the top strap portion can be coupled to the forehead support 1360 near the upper edge. The top strap portion can be connected to the display unit housing 1205 through the forehead support 1360.

[0451] In some forms, the top strap portion may be connected to the rear support portion 1350. For example, the top strap portion may be connected to the rear support portion 1350 near its upper edge.

[0452] In some forms, the top strap portion may cover the frontal and parietal bones of the user's head.

[0453] In some forms, the top strap portion may extend along a sagittal plane as it extends between the front and rear portions of the head mounted display system 1000.

[0454] In some forms, the top strap portion may apply a tensile force that is at least partially directed in an upward direction, which may counteract the force of gravity.

[0455] In some forms, the top strap portion can apply a tensile force that is at least partially directed in a posterior direction which can pull the interfacing structure 1100 toward the user's face (and provide a portion of the sealing force when the visor acts as a seal-forming structure).

[0456] In some forms, the top strap portion may be adjustable to apply a selective tension force on the display screen 1220 and / or the display unit housing 1205 to secure the position of the display screen 1220 and / or the display unit housing 1205 .

[0457] In some forms, the display unit housing 1205 and / or the forehead support 1360 (as appropriate) may include at least one loop or eyelet 1254, and the top strap portion may be passed through the eyelet 1254 and folded back on itself. The length of the top strap portion that passes through the eyelet 1254 may be selected by the user in order to adjust the tension provided by the positioning and stabilizing structure 1300. For example, passing a greater length of the top strap portion through the eyelet 1254 may provide greater tension.

[0458] In some forms, the top strap portion can include an adjustment portion and a receiving portion. The adjustment portion can be positioned through the eyelet 1254 and can be coupled to the receiving portion (e.g., by folding back on itself). The adjustment portion can include a hook material and the receiving portion can include a loop material (or vice versa) so that the adjustment portion can be removably retained in a desired position. In some examples, the hook material and the loop material can be Velcro.

[0459] Augmented reality display interface

[0460] 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 stabilizing 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.

[0461] 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 to the head mounted display system 1000, while in other instances, these may be modular and incorporated into the head mounted display system 1000 as desired by the user.

[0462] Interface connection structure

[0463] FIG. 7A to FIG. 7Q A view of an interface connection structure 1100 according to another example of the present technology is shown. The interface connection structure 1100 is for a head-mounted display system 1000 including a head-mounted display unit 1200, which includes a display unit housing 1205, and the display unit housing 1205 includes a display. In this example, the head-mounted display unit 1200 includes the interface connection structure 1100. The interface connection structure 1100 can be attached to the display unit housing 1205 in use, and can be constructed and arranged to be in relative relationship with the user's face in use. The head-mounted display system 1000 can additionally have any features, configurations, aspects, functions, etc. as described elsewhere herein. For example, the head-mounted display system 1000 may include a positioning and stabilization structure 1300, which is constructed and arranged to maintain the head-mounted display unit 1200 in an operable position on the user's head in use.

[0464] Chassis and face joints

[0465] The interfacing structure 1100 may include a face engaging portion 1110 configured to engage the face of a user in use. The face engaging portion 1110 may be flexible and resilient. The face engaging portion 1110 may be at least partially formed of an elastomeric material, such as silicone or TPE, for example.

[0466] It should be understood that unless the context requires otherwise, the interfacing structures and / or facial engaging portions described elsewhere herein (such as with reference to FIG. 4A to FIG. 4B or FIG. 5A to FIG. 5B Any features described) may be applied to, for example, FIG. 7A to FIG. 7Q The interface connection structure 1100 shown in FIG. The interface connection structure 1100 may be particularly suitable for a head mounted display system 1000 configured for VR, such as the reference FIG. 4A to FIG. 4B However, it should be understood that the reference 7A to 7O The interface connection structure 1100 or its individual features can be applied to a head-mounted display system 1000, which is configured for VR, MR, AR or any other artificial reality.

[0467] The interface connection structure 1100 may also include a chassis portion 1102 that is attached to the display unit housing 1205 in use. The chassis portion 1102 may be harder (e.g., have greater rigidity) than the facial engagement portion 1110. The facial engagement portion 1110 may be attached to the chassis portion 1102 and may be supported by the chassis portion 1102. The chassis portion 1102 may be configured to attach the interface connection structure 1100 to the head-mounted display unit 1200. For example, the chassis portion 1102 may be configured to attach to the display unit housing 1205 of the head-mounted display unit 1200. In some instances, the chassis portion 1102 may be at least partially formed of an elastomeric material, such as silicone or TPE. In other instances, the chassis portion 1102 may be at least partially formed of a thermoplastic material, such as polycarbonate, ABS, nylon, etc. The facial engagement portion 1110 may be at least partially formed of an elastomeric material, such as silicone or TPE. In some examples, the face engaging portion 1110 can be at least partially formed of foam. The chassis portion 1102 can additionally include a shape that requires a greater force to deform than the face engaging portion 1110. The face engaging portion 1110 can be formed separately from the chassis portion 1102 and subsequently attached to the chassis portion 1102.

[0468] The facial engaging portion 1110 may be configured to engage the user's face around the perimeter of the user's eyes during use. The facial engaging portion 1110 may be configured to engage the sides of the user's face outside the user's eyes and engage the user's forehead during use. The facial engaging portion 1110 may engage the user's cheeks, the sides of the user's face outside the user's eyes, and the user's forehead. The facial engaging portion 1110 may engage the user's face in an area covering the user's nose, maxilla, zygomatic bone, sphenoid bone, and frontal bone. For example, the facial engaging portion 1110 may engage the user's face in an area covering the user's nose, maxilla, zygomatic bone, sphenoid bone, and frontal bone. Figure 4D The user's face is engaged in the area shown.

[0469] In some examples, the face engaging portion 1110 and the chassis portion 1102 may include a single component that can be releasably fastened to the head mounted display unit 1200. The chassis portion 1102 may be configured to attach the interface connection structure 1100 to the head mounted display unit 1200, for example, by a snap fit. In other examples, the chassis portion 1102 may be attached to the head mounted display unit 1200 by an interference fit, a hook and loop fastening connection, a magnetic connection, and an interface connection structure clip or retainer that allows a friction fit, an interference fit, a snap fit, or any other suitable connection. In this example of the present technology, the interface connection structure 1100 includes an interface connection structure clip 1101 that is configured to be attached to a display unit housing 1205 of the head mounted display unit 1200 in use. The interface connection structure clip 1101 may be removably attached to the display unit housing 1205, for example, by a snap fit connection, a press fit connection, or other suitable connection, as disclosed elsewhere herein. In this example, the chassis portion 1102 of the interfacing structure 1100 is attached to the interfacing structure clip 1101, for example, by overmolding. In other examples, the chassis portion 1102 may be attached to the interfacing structure clip 1101 by adhesive and / or press fit. In other examples, there may be no interfacing structure clip 1101, and the chassis portion 1102 itself may form a releasable or permanent connection to the display unit housing 1205, such as a snap fit, press fit, adhesive connection, or other suitable connection means.

[0470] exist FIG. 7A to FIG. 7Q In the example shown, chassis portion 1102 includes cushion support portion 1103. Face engaging portion 1110 can be attached to cushion support portion 1103 of chassis portion 1102.

[0471] The face engaging portion 1110 may include a cushion 1130 and a face engaging membrane 1114. In this example, the face engaging membrane 1114 at least partially surrounds the cushion. The face engaging membrane 1114 may form a face contacting area 1112 that is configured to contact the user's face during use.

[0472] Behavior of interface structures

[0473] The face engaging portion 1110 is resiliently compressible to conform to the surface of the user's face during use. The chassis portion 1102 may be resiliently deformable to allow the face engaging portion 1110 to move relative to the display unit housing 1205. FIG. 7A to FIG. 7QIn the example shown, the face engaging portion 1110 may also be identified as a first portion of the interface connection structure 1100 and may include or form a first spring structure, and the chassis portion 1102 may also be identified as a second portion of the interface connection structure 1100 and may include or form a second spring structure. The face engaging portion 1110 may accommodate small variations in the shape of the user's facial surface, while the chassis portion 1102 may accommodate larger variations in the distance between the display unit housing 1205 and the user's facial surface. The two portions / spring structures may form a spring system and may work together to provide good engagement with user heads and faces of various shapes / sizes. The two spring structures may work in tandem to provide a large amount of available "travel" in the spring system to accommodate different distances between the display unit housing 1205 and the user's face (e.g., primarily using the second spring structure), while also accommodating smaller details in the shape of the user's facial surface (e.g., primarily using the first spring structure).

[0474] More generally, the interfacing structure 1100 in this and other examples of the present technology should be understood to include a second portion (e.g., FIG. 7A to FIG. 7Q The first portion (e.g., FIG. 7A to FIG. 7Q The second portion may be attached to the display unit housing 1205 in use and may form or include a support portion for the first portion. The first portion may be flexible and resilient and configured to engage the user's face in use. The first portion may be attached to the support portion of the second portion. FIG. 7A to FIG. 7Q In the particular example shown, the supporting portion of the second portion is a cushion supporting portion 1103 to which the face engaging portion 1110 is attached. Both the first portion and the second portion are configured to elastically deform in response to contact forces between the interfacing structure 1100 and the user's face in use.

[0475] In some instances, the first portion and the second portion have different responses to contact force. In some instances, the first portion (i.e., the first spring structure) and the second portion (i.e., the second spring structure) have different compression stiffnesses. For example, the first portion may have a smaller compression stiffness than the second portion. The first portion may be elastically compressible to conform to the surface of the user's face during use, which may facilitate the first portion to conform to small changes in the surface of the user's face, which may advantageously allow the first portion to conform to various facial surface shapes. At the same time, the second portion may be elastically deformable to allow the first portion to move relative to the display unit housing. This may enable the interface connection structure 1100 to fit a range of facial shapes and sizes well.

[0476] In some instances, the first portion and the second portion can simultaneously work together as a spring in series. In some instances, the first portion / spring structure can deform primarily through elastic material compression. The second portion / spring structure can deform primarily through elastic structure deformation. In some instances, the second portion can include multiple deformation modes. For example, the second portion can exhibit one or more of controlled articulation, flexure, buckling, bending, and material compression. By way of example only, in FIG. 7A to FIG. 7Q In the example shown, the first portion is a cushion 1130 that is deformed by compressing a cushion material (e.g., foam). The second portion is a chassis portion 1102, which in this example is an elastomeric structure that can deform in one or more of a variety of modes, including controlled flexing of the spacer portion 1104, bending of the spacer portion 1104, rotation of the spacer portion 1104 about its connection to the interface connection structure clamp 1101, bending of the cushion support flange, and rotation of the cushion support flange relative to the spacer portion 1104, all of which are described below. More generally, the second portion can allow the first portion to translate and / or rotate relative to the head mounted display unit 1200 in one or more areas of the first portion along the length of the first portion around the perimeter of the user's face. The following description focuses on FIG. 7A to FIG. 7Q In the example shown, reference will be made to the chassis portion 1102 and the face engaging portion 1110, but it will be understood that more generally, the face engaging portion 1110 forms the first portion / spring structure and the chassis portion 1102 forms the second portion / spring structure. In other examples, the physical configurations of the first portion / spring structure and the second portion / spring structure may be different while exhibiting the spring structure behavior described herein.

[0477] The chassis portion 1102 may allow the face engaging portion 1110 to rotate relative to the head mounted display unit 1200 around the perimeter of the user's face along the length of the face engaging portion 1110 in one or more areas of the face engaging portion 1110. In particular, the chassis portion 1102 may allow the face engaging portion 1110 to rotate inwardly relative to the head mounted display unit 1200, for example, to roll inwardly when the interfacing structure 1100 is in contact with the user's face during use.

[0478] The chassis portion 1102 can additionally or alternatively allow the face engaging portion 1110 to translate relative to the head mounted display unit 1200 along the length of the face engaging portion 1110 around the perimeter of the user's face in one or more areas of the face engaging portion 1110. For example, the sphenoid portion 1170 of the face engaging portion 1110 can translate laterally when the face engaging portion 1110 engages the user's face.

[0479] In particular, if Fig.7I , Figure 7P and Figure 7Q As shown in some cross-sectional views of , the chassis portion 1102 in this example includes one or more spacer portions 1104 arranged around the periphery of the user's eye area, each of the one or more spacer portions 1104 separating the cushion support portion 1103 from the display unit housing 1205. Each of the one or more spacer portions 1104 can be elastically deformable in use. The one or more spacer portions 1104 can serve as a support configured to deform in a controllable manner, such as bending, to allow movement of the face engaging portion 1110.

[0480] The one or more spacer portions 1104 may include a pair of spacer portions 1104, each spacer portion being configured to be at least partially located at a corresponding sphenoid region of a user's face during use. Alternatively or additionally, each spacer portion 1104 may be configured to be at least partially located at a corresponding cheek region of a user's face during use.

[0481] In the illustrated example, the chassis portion 1102 includes a spacer portion 1104, which is configured to be located at the cheek area and sphenoidal area of ​​the user's face in use. In this particular example, the spacer portion 1104 is not arranged in some or all of the forehead portions 1175. For example, one or more spacer portions 1104 do not intersect with the sagittal plane of the user's head in use. More specifically, in this example, each spacer portion 1104 extends from a middle position relative to a corresponding one of the cheeks of the user to at least the upper part of the corresponding sphenoidal portion along the length of the chassis portion 1102 around the periphery of the user's eye area in use. In addition, each spacer portion 1104 extends to at least the lateral area of ​​the user's forehead along the chassis portion on the corresponding side of the user's forehead in use. In particular, each spacer portion 1104 terminates at a position above the side edge of the corresponding one of the user's eyes that is substantially aligned.

[0482] In some examples, the transverse cross-sectional length of the spacer portion 1104 is different. The transverse cross-sectional length can be the length of the spacer portion 1104 around the perimeter of the user's eye area in use when measured in a cross section perpendicular to the length of the chassis portion 1102. For example, Figure 7C , Fig. 7E and Figure 7J As shown, each spacer portion 1104 can gradually decrease in transverse cross-sectional length at or near the side of the user's forehead. Fig. 7EAs shown, the spacer portion 1104 can have a maximum length at or near a midpoint of the side of the interface connection structure 1100, which midpoint can correspond to the midpoint of the height of the sphenoid region. The spacer portion 1104 can gradually decrease in length from those midpoints to the forehead region. In some instances, the spacer portion 1104 can gradually decrease in length between the sphenoid region and the cheek region (e.g., along the gradually decreasing area of ​​the spacer portion). In other instances, as an example, the chassis portion 1102 can include a spacer portion only in the sphenoid region of the interface connection structure 1100 or only in the cheek region of the interface connection structure 1100.

[0483] In this example of the present technology, the cushion support portion 1103 can be formed as a cushion support flange having a first end 1103a and a second end 1103b, the second end 1103b being able to move relative to the first end 1103a and the head mounted display unit 1200 during use. The second end 1103b can be a free end, so that the cushion support flange cantilevers out from the spacer portion 1104. The cantilever structure of the cushion support flange can allow it to bend relative to the spacer portion 1104. This ability of the cushion support flange to bend can form part of the behavior of the chassis portion 1102 as a second spring structure. In particular, the ability of the cushion support flange to bend relative to the spacer portion 1104 can enable the face engaging portion 1110 to rotate relative to the head mounted display unit 1200. In this way, the chassis portion 1102 allows the face engaging portion 1110 to translate and rotate. Therefore, the second portion / spring structure in this example (e.g., the chassis portion 1102 in the example shown) allows the first portion / spring structure to translate and rotate. In areas of the chassis portion 1102 where the chassis portion 1102 includes the spacer portion 1104, the first end 1103a of the cushion support flange is connected to the spacer portion 1104. However, in areas of the chassis portion 1102 where the chassis portion 1102 does not include the spacer portion 1104, the first end of the cushion support flange is directly connected to the interfacing structural clip 1101. The chassis portion 1102 may be overmolded to the interfacing structural clip 1101. Alternatively, the chassis portion 1102 may be removably attached to the interfacing structural clip 1101, such as by a press fit attachment.

[0484] The chassis portion 1102 can be configured to accommodate different head proportions by articulation, flexure, and / or flexure. Along the forehead region, the chassis portion 1102 can deform primarily by articulation. The pad support portion 1103 can articulate primarily about its connection to the interface connection structure clip 1101, although in some instances (additionally or alternatively) can bend, as discussed in more detail below.

[0485] Fig. 8A , Figure 8B and Fig. 9 The illustrations show how the chassis portion 1102 can allow the face engaging portion 1110 to rotate relative to the head mounted display unit 1200. For clarity, the face engaging portion 1110 is not shown in these figures in order to illustrate how the cushion support portion 1103 can move or deform. In these illustrations, 1103 represents the original "resting" shape of the cushion support portion 1103, depicted in dotted lines, while 1103' represents the cushion support portion 1103 in a deformed shape during use, depicted in solid lines. Reference numerals 1103a and 1103b represent the first and second ends of the cushion support flange in an undeformed state, while reference numerals 1103a' and 1103b' represent the positions of the first and second ends of the cushion support flange in a deformed state.

[0486] Fig. 8A and Figure 8B 100 is shown in cross-section in the forehead region, with the face engaging portion 1110 omitted, showing two different modes in which the cushion support portion 1103 can be deformed. In these examples, the cushion support portion 1103 can bend near its connection with the interfacing structure clip 1101. Fig. 8A As shown, the cushion support portion 1103 (e.g., the cushion support flange in this example) can be bent so that the second end 1103b of the cushion support flange moves relative to the first end 1103a. The first ends 1103a and 1103a' are substantially located at the same position, but the deformed cushion support flange second end 1103b' has moved away from the position of the undeformed cushion support flange second end 1103b. Figure 8B In the example shown, the cushion support portion 1103 or at least a portion thereof can rotate (e.g., deform to rotate). In the example shown, the cushion support portion 1103 can rotate relative to the display unit housing 1205 or the interface connection structure clip 1101. Figure 8B As shown, the pad support portion 1103 (e.g., the pad support flange in this example) has been rotated so that the second end 1103b of the pad support flange has moved relative to the first end 1103a. In this example, the rotation occurs substantially around the first end 1103a. In some examples, the pad support portion 1103 can be rotated in use. Fig. 8A and Figure 8B The two deformation modes shown are deformed simultaneously. In other examples, the pad support portion 1103 can deform according to a first mode in at least one region of the interfacing structure (e.g., a forehead portion) and deform according to a second mode in at least one other region of the interfacing structure (e.g., a cheek portion and / or a sphenoid portion).

[0487] Fig. 9100 is shown in a cross-sectional view of the interface connection structure 1100 in the cheek region. In this example, the cushion support portion 1103 (in this example, the cushion support flange) is hinged at its connection with the spacer portion 1104. Fig. 9 As shown, the second end 1103b' of the cushion support flange in the deformed state has moved from the position of the second end 1103b in the undeformed state. At the same time, the first end 1103a is in substantially the same position. In some examples, the spacer portion can also be deformed, such as by bending along its length and / or by rotating / hinging about its connection with the display unit housing 1205 (e.g., at or near the interface connection structure clip 1101 in the example shown).

[0488] Along the sphenoid portion, the chassis portion 1102 can deform primarily by flexing. In some instances, the chassis portion 1102 or one or more portions thereof can bend, for example to accommodate the width of the user's head and / or to provide a resilient cushion to comfortably maintain the facial engagement portion 1110 in contact with the user's face. In some instances, the chassis portion 1102 can be configured to allow flexion (e.g., controlled flexion / flexion in a controlled manner) in one or more portions of the chassis portion 1102 (such as in the spacer portion 1104 or the cushion support portion 1103) near the user's ball region. For example, such controlled flexion may occur when the head-mounted display system 1000 is worn by a user with a particularly wide head.

[0489] In some forms of the present technology, the chassis portion 1102 (or its spacer portion 1104 or cushion support portion 1103) may deform by flexing / bending at a relatively low force, but may subsequently deform by flexing in response to a predetermined level of force (e.g., controlled flexion). After flexion is initiated, the force required to further deform the chassis portion 1102, or one or more portions thereof, may be equal to or less than the predetermined level of force required to initiate flexion. Once flexion is initiated, this reduction in force (or reduction in increase in force / prevention of increase in force) may advantageously allow the chassis portion 1102 to deform over a large distance (e.g., a large "travel") without the restoring forces on the face engaging portion 1110 becoming uncomfortably large under greater compression. This may allow the interfacing structure 1100 to comfortably fit a wide range of facial shapes and sizes.

[0490] FIG. 10A to FIG. 10C The diagram shows how the chassis portion 1102 or its spacer portion 1104 deforms in the above-described manner during use. For the sake of clarity, the face engaging portion 1110 is also not shown in these figures. Fig. 10AAn initial manner / mode of deformation is shown. In this figure, the undeformed shape of the chassis portion 1102 is shown in dashed lines, and reference numerals 1103 are given to the pad support portion and 1104 are given to the spacer portion, each of which is in its undeformed state. The shape of the chassis portion 1102 in the deformed state is shown in solid lines, and reference numerals 1103' and 1104' are given to the pad support portion and the spacer portion, respectively. As shown, in response to an initial or low level of force, the spacer portion 1104 can bend or flex into the shape of the deformed spacer portion 1104'. This can allow the pad support portion 1103 to move, such as by Fig. 10A The translation shown.

[0491] Fig. 10B A second mode / approach of deformation that may occur after additional forces are applied to the interfacing structure 1100 is shown, which may occur if the head mounted display system 1000 is used by a user with a particularly large or wide head. Fig. 10B In the figure, the moderately deformed spacer portion 1104' is shown in dashed lines, which has the same Fig. 10A Under the action of additional force, the spacer portion 1104 can further bend and deform to become Fig. 10B The shape of the flexed spacer portion 1104" is shown in solid line. As described above, during or prior to flexion, the reaction force applied back onto the user's face by the interfacing structure 1100 can be reduced (or in some instances can at least remain constant) to allow for a large "travel" of the face engaging portion 1110 without excessive spring return force being applied back onto the user's face.

[0492] Fig. 10C Three shapes of the chassis portion 1102 are depicted throughout the above-described deformation process. As shown, the spacer portion in a first, undeformed state is shown in dashed lines and given the reference numeral 1104. In a second state, the spacer portion has been bent / flexed outwardly and is shown in dashed lines and given the reference numeral 1104'. Finally, in a third state, the spacer portion has buckled, providing further deformation, and is shown in solid lines and given the reference numeral 1104". Fig. 10C As shown, in this example, continuous deformation of the chassis portion 1102 allows the pad support portion 1103 to continuously move outward (e.g., laterally and partially rearward). The positions of the pad support portions are indicated by reference numerals 1103, 1103', and 1103". In some examples, the pad support portion 1103 can also be deformed, for example by bending along its length or by articulating around its connection to the spacer portion 1104.

[0493] exist FIG. 7A to FIG. 7QIn the example shown, the face engaging membrane 1114 includes a first end 1111 and a second end 1113, with the face contacting area 1112 located between the first end 1111 and the second end 1113, and the first end is attached to the chassis portion 1102. The first end 1111 and the second end 1113 can be the ends of the cross-sectional shape of the face engaging membrane 1114. In particular, the first end 1111 of the face engaging membrane 1114 is attached to the cushion support portion 1103. Figure 7H , Fig.7I , Figure 7L , Figure 7M , Figure 7P and Figure 7Q As shown, the first end 1111 of the face engaging film 1114 is attached to the first end 1103a of the cushion support flange. The face engaging film 1114 can be curled around the cushion 1130 between the face contact area 1112 and the second end 1113 of the face engaging film 1114. The second end 1113 of the face engaging film 1114 can be attached to the cushion support flange at or near the second end 1103b of the cushion support flange. The face engaging film 1114 in the example shown can contact the user's face on the same side of the film attached to the cushion support flange. The face engaging film 1114 can be curled around the cushion 1130 far enough so that it is attached to the cushion support flange between the cushion support flange and the cushion 1130. The face engaging film 1114 can achieve this at the first end 1111 and the second end 1113 of the face engaging film 1114. This can advantageously provide a soft or unobtrusive joint between the face engaging film 1114 and the cushion support flange.

[0494] In the illustrated example, the cushion 1130 is formed of foam. In other examples, the cushion 1130 may be formed of gel, silicone or other suitable materials. The facial engaging membrane 1114 may be formed of an elastomeric material. In other examples, the facial engaging membrane 1114 is formed of silicone. In other examples, it may be formed of a thermoplastic elastomer. When used with an elastically deformable chassis portion 1102, it may be advantageous to use an elastic material such as an elastomeric material. Specifically, when the chassis portion 1102 is deformed outwardly in the spherical body portion, the material forming the facial engaging membrane 1114 may be stretched due to the overall widening of the facial engaging portion 1110. Forming the facial engaging membrane 1114 of an elastic material may advantageously allow the facial engaging membrane 1114 to stretch in the forehead region to accommodate such widening, which may allow the facial engaging portion 1110 to better maintain a predetermined curvature in the forehead region, which may promote a good fit.

[0495] Thickness of face bonding film

[0496] Reference now FIG. 11A to FIG. 11J, the face engaging portion 1110 in this example includes a pair of cheek portions 1140, which are configured to engage the cheeks of the user in use. In this example, the face engaging portion 1110 is also configured to engage the sides of the user's face outside the user's eyes in use, and is also configured to engage the user's forehead. The portions that engage the sides of the user's face outside the user's eyes can be identified as sphenoid portions 1170. That is, the face engaging portion 1110 may include a pair of sphenoid portions 1170, each sphenoid portion 1170 being configured to engage the corresponding sphenoid region of the user's face in use. The portion that engages the user's forehead can be identified as forehead portion 1175. That is, the face engaging portion 1110 may include a forehead portion 1175 configured to engage the user's forehead. In an example, the interface connection structure 1100 may include any one, two, or three of the cheek portions 1140, the sphenoid portions 1170, and the forehead portion 1175.

[0497] FIG. 11A to FIG. 11J The illustrated interfacing structure 1100 includes a face engaging portion 1110 including a face engaging membrane 1114 and a cushion 1130, the face engaging portion 1110 being as described above with reference to FIG. 7A to FIG. 7Q The interface structure 1100 may be connected to the chassis portion 1102 and the interface structure clip 1101 in the manner described above. FIG. 8A to FIG. 10C Some or all of the same behaviors described.

[0498] In some examples, the facial engaging film 1114 has different thicknesses at different areas of the user's face. In some examples, the thickness of the facial engaging film 1114 varies from the first end 1111 toward the second end 1113. For example, the thickness of the facial engaging film 1114 can decrease from the first end 1111 to the second end 1113 or toward the second end 1113.

[0499] FIG. 11A to FIG. 11J The facial engaging membrane 1114 shown has different thicknesses in different areas. FIG. 13A to FIG. 13C 1 shows a view of a facial engaging film 1114 according to another example of the present technology, which also has different thicknesses in different areas. In some forms of the present technology, FIG. 11A to FIG. 11J The facial engaging membrane 1114 in the example shown may replace FIG. 13A to FIG. 13C The facial engaging membrane 1114 is shown. FIG. 13A to FIG. 13C In the view of the facial bonding membrane 1114 according to FIG. 13A to FIG. 13CThe legend of each of the uses stippling to indicate the difference in thickness. For example, the facial bonding film 1114 can have a thickness in a first thickness range A (about 0.01 mm to about 0.61 mm), a second thickness range B (about 0.61 mm to about 1.0 mm), a third thickness range C (about 1.0 mm to about 1.21 mm), a fourth thickness range D (about 1.21 mm to about 1.55 mm), a fifth thickness range E (about 1.55 mm to about 2.20 mm), and a sixth thickness range F (about 2.20 mm to about 3.10 mm). Although in FIG. 13A to FIG. 13C 11. Multiple discrete regions with defined boundaries are shown in FIG. 11, but it should be understood that the facial engaging membrane 1114 may include a thickness that tapers between regions. FIG. 13A to FIG. 13C The discrete regions depicted in correspond to the intervals (or thickness ranges A, B, C, D, E, and F) shown in the legend and do not necessarily correspond to step changes in thickness. In an example, the thickness difference within the facial bonding film 1114 can be formed by a tapered change in thickness or a step change in thickness.

[0500] In some examples, the face engaging membrane 1114 is thicker in the forehead portion 1175 than in the sphenoid portion 1170. In some examples, the face engaging membrane is thicker in the cheek portions 1140 than in the forehead portion 1175. The face engaging membrane 1114 can be thicker at an outer portion of the face engaging membrane 1114 relative to the user's eye area than at an inner portion of the face engaging membrane 1114 relative to the user's eye area.

[0501] In some examples, the facial engaging membrane 1114 has a thickness in the sphenoid portion 1170 in a range of 0.3 to 1.5 mm. Fig.11J A cross-sectional view through one of the sphenoid portions 1170 of the face engaging portion 1110 is shown, wherein the pad 1130 is omitted. As shown, the face engaging membrane 1114 in this example has a cross-sectional shape with a thickness decreasing from the outer portion 1114a of the cross-sectional shape to the inner portion 1114b of the cross-sectional shape. That is, the face engaging membrane 1114 has a thickness decreasing from the outer portion 1114a of the cross-sectional shape of the face engaging membrane 1114 to the inner portion 1114b. In this example and other examples, the face engaging membrane 1114 can reduce the thickness by gradually reducing the thickness, either gradually reducing in a continuous manner or gradually reducing in a step manner. In this particular example, the thickness of each of the cross-sectional shapes of the face engaging membrane 1114 in the sphenoid portions 1170 is reduced from about 1.2 mm to about 0.5 mm. In some examples, the facial engaging membrane 1114 can have four different thicknesses around its cross-sectional shape in the sphenoid portion 1170, such as a first thickness of about 1.2 mm, a second thickness of about 0.8 mm, a third thickness of about 0.6 mm, and a fourth thickness of about 0.5 mm.

[0502] like FIG. 13A to FIG. 13C As shown, the facial engaging membrane 1114 in this example includes a first portion 1170a, a second portion 1170b, and a third portion 1170c in the sphenoid portion 1170. The facial engaging membrane 1114 can have a greater thickness in the first portion 1170a than in the second portion 1170b, and can have a greater thickness in the second portion 1170b than in the third portion 1170c. The first portion 1170a can also be identified as the rearmost portion or outermost portion (e.g., radially outermost or at the outer periphery) of the corresponding sphenoid portion 1170. The third portion 1170c can be identified as the frontmost portion or innermost portion (e.g., radially innermost or at the inner periphery) of the corresponding sphenoid portion 1170. The second portion 1170b can be located between the outermost portion and the innermost portion. In this example, the first portion 1170a can have a thickness of about 1.25 mm, the second portion 1170b can have a thickness of about 0.8 mm, and the third portion 1170c can have a thickness of about 0.6 mm. In some examples, the third portion 1170c can also have a thickness of about 0.5 mm at or near the innermost perimeter of the facial engaging membrane 1114.

[0503] In the forehead portion 1175, the facial engaging membrane 1114 can have a thickness in the range of 0.8 to 1.8 mm. Fig.11G A cross-sectional view through the forehead portion 1175 of the face engaging portion 1110 is shown, wherein the cushion 1130 is omitted. As shown, the face engaging membrane 1114 in this example has a cross-sectional shape with a thickness decreasing from an outer portion 1114a of the cross-sectional shape to an inner portion 1114b of the cross-sectional shape. In this example, the cross-sectional shape of the face engaging membrane 1114 gradually decreases in thickness from about 1.6 mm to about 1 mm in the forehead portion 1175. In some examples, the face engaging membrane 1114 can have three different thicknesses around its cross-sectional shape in the forehead region 1175, such as a first thickness of about 1.6 mm, a second thickness of about 1.2 mm, and a third thickness of about 1 mm.

[0504] like FIG. 13A to FIG. 13CAs shown, the facial engaging film 1114 in this example includes a first portion 1175a, a second portion 1175b, and a third portion 1175c in the forehead portion 1175. The facial engaging film 1114 can have a greater thickness in the first portion 1175a than in the second portion 1175b, and can have a greater thickness in the second portion 1175b than in the third portion 1175c. The first portion 1175a can also be identified as the uppermost or outermost portion of the forehead portion 1175 (e.g., radially outermost or at the outer periphery). The third portion 1175c can be identified as the lowermost or innermost portion of the forehead portion 1175 (e.g., radially innermost or at the inner periphery). The second portion 1175b can be located between the outermost portion and the innermost portion. In this example, the first portion 1175a can have a thickness of about 1.6 mm, the second portion 1175b can have a thickness of about 1.2 mm, and the third portion 1175c can have a thickness of about 1 mm.

[0505] In some examples, the facial engaging membrane 1114 can have a thickness in the range of 0.8 mm to 3 mm in each of the cheek portions 1140 . Fig.11I A cross-sectional view through one of the cheek portions 1140 of the face engaging portion 1110 is shown, wherein the liner 1130 is omitted. As shown, the face engaging membrane 1114 in this example has a cross-sectional shape that decreases in thickness from the outer portion 1114a of the cross-sectional shape to the inner portion 1114b of the cross-sectional shape. In this example, the cross-sectional shape of the face engaging membrane 1114 decreases in thickness from about 2.5 mm to about 1 mm in each of the cheek portions 1140. In some examples, the face engaging membrane 1114 can have five different thicknesses around its cross-sectional shape in the cheek portions 1140, such as a first thickness of about 2.5 mm, a second thickness of about 2.1 mm, a third thickness of about 2 mm, a fourth thickness of about 1.5 mm, and a fifth thickness of about 1 mm.

[0506] like FIG. 13A to FIG. 13CAs shown, the facial engaging film 1114 in this example includes a first portion 1140a, a second portion 1140b, a third portion 1140c, and a fourth portion 1140d in each cheek portion 1140. The facial engaging film 1114 can have a greater thickness in the first portion 1140a than in the second portion 1140b, can have a greater thickness in the second portion 1140b than in the third portion 1140c, and can have a greater thickness in the third portion 1140c than in the fourth portion 1140d. The first portion 1140a can also be identified as the lowermost or outermost portion (e.g., radially outermost or at the outer periphery) of the corresponding cheek portion 1140. The fourth portion 1140d can be identified as the uppermost or innermost portion (e.g., radially innermost or at the inner periphery) of the corresponding cheek portion 1140. The second portion 1140b and the third portion 1140c can be located between the outermost portion and the innermost portion. In this example, the first portion 1140a may have a thickness of approximately 2.5 mm, the second portion 1140b may have a thickness of approximately 1.7 mm, the third portion 1140c may have a thickness of approximately 1.2 mm, and the fourth portion may have a thickness of approximately 1 mm.

[0507] It should be understood that in the above description, a portion (e.g., first, second, third, etc.) of the face-engaging film 1114 "having" a specific thickness means that the face-engaging film 1114 has the thickness somewhere within the specific portion. It should not be understood to uniquely indicate that the entire portion has a uniform thickness. In some examples, the face-engaging film 1114 can be continuously tapered, but can still have the portions disclosed above.

[0508] In some examples, the face-engaging membrane 1114 at the middle portion of each cheek portion 1140 can have a thickness in the range of 0.4 to 0.8 mm, such as 0.5 to 0.7 mm, such as about 0.6 mm. The middle portion of each cheek portion 1140 can be located at a middle position along the cheek portion 1140 and at an inner portion of the cross-sectional shape of the face-engaging membrane 1114. Fig.11H Shown is a cross-sectional view through the middle portion of one of the cheek portions 1140. At this location, the cheek portion 1140 may transition into a wing portion 1145, which will be described below.

[0509] The reduction in thickness of the facial engaging film 1114 from the outer portion 1114a of the cross-sectional shape to the inner portion 1114b of the cross-sectional shape can advantageously allow for a thicker and harder area at the outer portion 1114a that may not contact the user's face, and a thinner and more flexible area at the inner portion 1114b at the inner edge of the contact area between the facial engaging film 1114 and the user's face. The thicker outer portion 1114a can provide good support for the cross-sectional shape of the facial engaging film 1114 to resist buckling and excessive compression, while the thinner inner portion 1114b can allow for a comfortable feel to the user's face. That is, the relatively small thickness of the radially inner portion enables the facial engaging film 1114 to be easily flexed when engaged with the user's skin to provide a comfortable wearing engagement against the user's face. The relatively large thickness of the radially outer portion provides support for the radially inner portion and has sufficient stiffness / rigidity (e.g., resistance to overall shape deformation of the interface connection structure) to enable the interface connection structure to be stably engaged with the user's face.

[0510] exist FIG. 11A to FIG. 11F In the examples shown, particular reference is made to Fig. 11B and Fig.11F , the facial engaging portion 1110 may also include a pair of wing portions 1145. The wing portions 1145 may be located in the middle of the cheek portions 1140, and each wing portion 1145 may be configured to be positioned against or near a corresponding side of the user's nose. For example, the wing portions 1145 may be located on either side of the user's nose during use, and depending on the shape and size of the user's nose, the wing portions 1145 may be close to the user's nose or may contact both sides of the user's nose. Preferably, the wing portions 1145 are close to but do not engage both sides of the user's nose. In use, the wing portions 1145 may be located near the lower periphery of the user's nose, such as near the nose wing.

[0511] The face engaging membrane 1114 can have a smaller thickness in the wing portion 1145 than in the cheek portion 1140, the sphenoid portion 1170, and / or the forehead portion 1175. In particular, the face engaging membrane 1114 in the wing portion 1145 can have a smaller thickness than in the cheek portion 1140. In some examples, the thickness of the wing portion 1145 can be less than half of the minimum thickness of the cheek portion 1140. By way of example only, the thickness of the face engaging membrane 1114 can be in the range of 0.2 to 0.6 mm, such as in the range of 0.25 to 4 mm, or in some examples, about 0.3 mm or about 0.5 mm.

[0512] The thickness of the facial engaging membrane 1114 in the wing portions 1145 can advantageously be relatively low, such as approximately 0.3 mm as described above, so that any contact that may occur between the wing portions 1145 and the user's nose is not uncomfortable and to avoid unnecessary weight being added to the interfacing structure 1100 (e.g., since the wing portions 1145 may not need to resist significant compression during use, they can be made thin and light). The facial engaging membrane 1114 in the cheek portions 1140 can be made thicker than in the wing portions 1145 because the cheek portions 1140 engage the user's cheeks and need to resist compression when they support the head mounted display unit 1200 on the user's face during use. FIG. 13A to FIG. 13C In the example shown, the face engaging membrane 1114 includes a wing portion 1145, which in this particular example has a thickness of approximately 0.5 mm.

[0513] from FIG. 13A to FIG. 13C As is apparent from the above related description, there are certain relationships between the thickness of the facial bonding membrane 1114 in different areas of the interfacing structure 1100. These relationships can provide the advantages discussed below (e.g., good support against bottoming out even without the top band portion being incorporated, usability with the eyes, good stability during vigorous exercise, and the ability to accommodate a wide range of facial shapes and sizes while being comfortable for a wide range of users). In particular, the facial bonding membrane 1114 can be thicker in the forehead portion 1175 than in the sphenoid portion 1170. Additionally, the facial bonding membrane can be thicker in the cheek portions 1140 than in the forehead portion 1175. Additionally, FIG. 11A to FIG. 11J and FIG. 13A to FIG. 13C The facial engaging membrane 1114 in the illustrated example has an outer perimeter 1176 (eg, a perimeter further away from the user's eyes during use) and an inner perimeter 1177 (eg, a perimeter closer to the user's eyes during use).

[0514] Specific as FIG. 13A to FIG. 13C As shown, the facial engaging membrane 1114 includes an outer peripheral thickness in the forehead portion 1175 and an outer peripheral thickness in the sphenoid portion 1170, the outer peripheral thickness in the forehead portion 1175 being greater than the outer peripheral thickness in the sphenoid portion 1170. The facial engaging membrane 1114 may also include an outer peripheral thickness in the cheek portions 11140 that is greater than the outer peripheral thickness in the forehead portion 1175.

[0515] The face engaging membrane 1114 may include an inner perimeter thickness in the forehead portion 1175 and an inner perimeter thickness in the sphenoid portion 1170, the inner perimeter thickness in the forehead portion 1175 being greater than the inner perimeter thickness in the sphenoid portion 1170. The face engaging membrane 1114 may also include an inner perimeter thickness in the cheek portions 1140 that is greater than the inner perimeter thickness in the sphenoid portion 1170. The inner perimeter thickness in the forehead portion 1175 may be substantially the same as the inner perimeter thickness in the cheek portions 1140.

[0516] The above relationship indicates that in each of the sphenoid portion 1170, the forehead portion 1175, and the cheek portion 1140, the facial bonding membrane 1114 is thicker at the outer periphery than at the inner periphery. In addition, the thickness of the sphenoid portion 1170 is generally less than the thickness of the forehead portion 1175 and the cheek portion 1140. For example, the facial bonding membrane 1114 in the sphenoid portion 1170 can decrease from medium thickness to very thin, while the facial bonding membrane 1114 in the cheek portion 1140 can decrease from very thick to medium thickness in the cheek portion 1140. Reference to the facial bonding membrane 1114 that decreases in thickness from the outer periphery to the inner periphery at a particular location should be understood as a reference to the facial bonding membrane 1114 that decreases in thickness in a transverse cross-section (e.g., a cross-section that is transverse to the path of the interfacing structure around the user's eyes in use). For the avoidance of doubt, Fig.11G and Fig.11J A transverse cross-sectional view through the face engaging membrane 1114 is shown.

[0517] As above reference FIG. 13A to FIG. 13C As described, the facial engaging membrane 1114 includes a first portion 1170a, a second portion 1170b, and a third portion 1170c in each sphenoid portion 1170. In this example, the outer peripheral thickness of each sphenoid portion 1170 is within the first portion 1170a of the sphenoid portion 1170, and the inner peripheral thickness of each sphenoid portion 1170 is within the third portion 1170c of the sphenoid portion 1170. The thickness of the facial engaging membrane 1114 in the second portion 1170b of the sphenoid portion 1170 may be smaller than the thickness in the first portion 1170a of the sphenoid portion 1170 and greater than the thickness in the third portion 1170c of the sphenoid portion 1170.

[0518] Similarly, as mentioned above FIG. 13A to FIG. 13CAs described, the facial engaging film 1114 includes a first portion 1175a of the forehead portion 1175, a second portion 1175b of the forehead portion 1175, and a third portion 1175c of the forehead portion 1175 in the forehead portion 1175. In this example, the outer peripheral thickness of the forehead portion 1175 is within the first portion 1175a of the forehead portion 1175, and the inner peripheral thickness of the forehead portion 1175 is within the third portion 1175c of the forehead portion 1175. The thickness of the facial engaging film 1114 in the second portion 1175b of the forehead portion 1175 is smaller than the thickness in the first portion 1175a of the forehead portion 1175 and is greater than the thickness in the third portion 1175c of the forehead portion 1175.

[0519] like FIG. 13A to FIG. 13C As shown, the facial engaging membrane 1114 has a thickness in the second portion 1175 b of the forehead portion 1175 that is greater than the thickness in the second portion 1170 b of each sphenoid portion 1170 .

[0520] Similarly, as mentioned above FIG. 13A to FIG. 13C As described, the facial engaging membrane 1114 includes a first portion 1140a of the cheek portion 1140, a second portion 1140b of the cheek portion 1140, a third portion 1140c of the cheek portion 1140, and a fourth portion 1140d of the cheek portion 1140 in each cheek portion 1140. In this example, the outer peripheral thickness of each cheek portion 1140 is within the first portion 1140a of each cheek portion 1140, and the inner peripheral thickness of each cheek portion 1140 is within the fourth portion 1140d of each cheek portion 1140. The thickness of the facial engaging membrane 1114 in the second portion 1140b of each cheek portion 1140 is greater than the thickness in the second portion 1170b of each sphenoid portion 1170. For example, as Fig.13A As shown, the thickness in the second portion 1140b of each cheek portion 1140 is greater than the thickness in the second portion 1175b of the forehead portion 1175. The thickness in the second portion 1140b of each cheek portion 1140 may be substantially the same as the thickness in the first portion 1175a of the forehead portion 1175. In the example shown, the thickness of the facial engaging membrane 1114 in the third portion 1140c of each cheek portion 1140 is greater than the thickness in the second portion 1170b of each sphenoid portion 1170. The thickness in the third portion 1140c of each cheek portion 1140 is substantially the same as the thickness in the second portion 1175b of the forehead portion 1175.

[0521] The facial engaging membrane 1114 in the cheek portions 1140 and forehead portion 1175 is provided with sufficient thickness, which can advantageously provide good support for the head mounted display unit 1200 in use and help prevent the interfacing structure 1100 from "bottoming out" when compressed when the positioning and stabilizing structure 1300 is tightened. The relatively high thickness in the cheek portions 1140 and forehead portion 1175 (relative to the sphenoid portion 1170 and wing portion 1145) can allow the head mounted display system 1000 to be used without a top strap on the top of the user's head. Fig.12 Shown include FIG. 11A to FIG. 11J An example of a head mounted display system 1000 with an interface connection structure 1100 is shown. In this example, the head mounted display system 1000 includes a positioning and stabilizing structure 1300, which includes a top strap portion 1340 and an outer strap portion 1330. The top strap portion 1340 and the outer strap portion 1330 are connected between a rear support portion 1350 of the positioning and stabilizing structure 1300 and a display unit housing 1205, and the interface connection structure 1100 is also attached to the display unit housing 1205. However, in other examples, the top strap portion 1340 may not be included. When the top strap is not incorporated into the positioning and stabilizing structure 1300, the lateral support portion 1330 needs to pull the head mounted display unit 1200 against the user's face in a rearward direction with sufficient force so that the head mounted display unit 1200 is maintained in a stable position. The interface connection structure 1100 is then compressed and needs to withstand the force, preferably without bottoming out (which may be uncomfortable for the user). The heavier the head mounted display unit 1200, the greater the force that the interface connection structure 1100 needs to withstand. Sufficient thickness in the forehead portion 1175 and the cheek portion 1140 helps to withstand this force, advantageously enabling the head mounted display system 1000 to be used without a top strap.

[0522] The sphenoid portion 1170 can be provided with a lesser thickness than the cheek portions 1140 and the forehead portion 1175 to allow the face engaging portion 1110 to be flexible on its sides. Since the sphenoid portion 1170 faces inward to a greater extent than the cheek portions 1140 and the forehead portion 1175, they will not resist as much of the "clamping" force directed backwards and can therefore be made thinner. In addition, the additional flexibility in the sphenoid portion 1170 allows the face engaging portion 1110 to better withstand glasses, thereby allowing users who need glasses to use the head mounted display system 1000 more conveniently. In addition, the flexibility of the sphenoid portion 1170 allows the face engaging portion 1110 to open laterally to fit wide faces / large heads, allowing the interface connection structure 1100 to be used comfortably and stably by a wide range of users. Therefore, in a preferred embodiment, the interface connection structure 1100 can advantageously provide good support, even in the absence of the top strap portion 1340, while allowing glasses and a wide range of user head shapes and sizes. In some examples, the sphenoid portion 1170 can include the smallest thickness of the face contacting region 1112 of the face engaging membrane 1114. The relatively smaller thickness (e.g., particularly the inner perimeter thickness) in the sphenoid portion 1170 as compared to other portions (e.g., the forehead portion 1175 and / or the cheek portions 1140) allows the face engaging membrane 1114 in the sphenoid portion to flex to accommodate the curvature in this area of ​​the face while also accommodating anthropometric differences between users.

[0523] Nose

[0524] Specific reference 7A to 7E and FIG. 11A to FIG. 11F , the face engaging portion 1110 may, in some forms, include a nose portion 1180 that is configured to engage a user's nose in use. The nose portion 1180 may be configured to at least partially block light from the user's nasal region from reaching the user's eyes (e.g., blocking light from traveling via a path near a surface of the user's nose). The nose portion 1180 may, for example, be configured to engage a front surface, an upper surface, and / or a side surface of a user's nose in use. The nose portion 1180 may be located between the cheek portions 1140 of the interfacing structure 1100.

[0525] like FIG. 11A to FIG. 11FAs shown, the nose portion 1180 in this example includes a lower portion 1182, which can be positioned near the nasal prominence of the user during use. In addition, the nose portion 1180 in this example includes a first wing 1186 and a second wing 1187, each of which is connected to the lower portion 1182. The first wing 1186 can be configured to engage a first side of the user's nose during use, and the second wing 1187 can be configured to engage a second side of the user's nose during use. In this example, the first wing 1186 and the second wing 1187 are separated by a narrow slot 1188. The narrow slot 1188 is Fig.11A , Fig. 11C and Fig.11F The lower portion 1182 may be generally concave, although it may include complex curvatures rather than being completely spherical. In the illustrated example, the lower portion 1182 may occupy space above and / or outside the nasal prominence of the user during use.

[0526] The first wing 1186 and the second wing 1187 can contact the user's nose along the nasal ridge and can extend toward the user's nose bridge point. The first wing 1186 and the second wing 1187 can extend to the user's nose bridge point or can only extend partially along the user's nasal ridge. In some examples, the nose portion 1180 can contact a majority of the user's nasal ridge during use. The first wing 1186 can be located on a first side of the midsagittal plane of the user's head, and the second wing 1187 can be located on a second side of the midsagittal plane of the user's head. FIG. 11A to FIG. 11F In the example shown, the first wing 1186 and the second wing 1187 bridge between the portion of the interfacing structure 1100 proximal to the cheek portion 1140 and the corresponding sides of the user's nose.

[0527] For example, Fig.11A As shown, the slot 1188 can extend from the rear edge of the nose portion 1180 toward the lower portion 1182 between the first wing 1186 and the second wing 1187. The first wing 1186 and the second wing 1187 can be configured to engage the corresponding sides of the user's nose in use. For example, they can be located on the side of the user's nose. When the user wears the head-mounted display system 1000, the first wing 1186 and the second wing 187 can be lifted by the user's nose. Lifting the first wing 1186 and the second wing 1187 so that they rest on the surface of the user's nose can help the wing to conform well to the user's nose, thereby providing a good light blocking effect. For example, as a result of the slot 1188, the wing can contact the user's nose with little or no wrinkles.

[0528] The material forming the first wing 1186 and the second wing 1187 can be thin so that the wing can at least partially conform to the user's nose. FIG. 11A to FIG. 11FIn the example shown, the nose portion 1180 is connected to the chassis portion 1102 of the interfacing structure 1100. For example, the nose portion 1180 can be integrally formed with the chassis portion 1102. FIG. 7A to FIG. 7Q In the example shown, the nose portion 1180 is connected to the face engaging membrane 1114 and can be formed integrally with the face engaging membrane 1114. Forming the nose portion 1180 integrally with the chassis portion 1102 rather than with the face engaging membrane 1114 can allow the face engaging membrane 1114 to be more complex than otherwise possible, or can reduce the cost of manufacturing a complex face engaging membrane 1114 that is highly stable and / or highly comfortable in use and that can fit a wide range of users well.

[0529] like FIG. 11A to FIG. 11F As shown, the nose portion includes a lower portion 1182, which is positioned close to the nasal prominence of the user in use. In this example, the lower portion 1182 can be the frontmost and lowermost portion of the nose portion 1180. The nose portion can generally extend backward and upward from the lower portion 1182.

[0530] like FIG. 11A to FIG. 11D As shown, the nose portion 1180 in this example includes an opening 1185 in the front-most portion of the nose portion 1180. In this example, the opening 1185 is partially defined by the lower portion 1182 of the nose portion 1180. Also in this example, the opening is partially defined by the interface connection structure clip 1101, such that the opening is disposed between the interface connection structure clip 1101 and the lower portion 1182. The lower portion 1182 of the nose portion 1180 can define the upper side and the side of the opening 1185, and the interface connection structure clip 1101 can define the lower side of the opening 1185. Fig.11A As shown, in this example, the lower side of the opening 1185 is bent in the posterior direction on either side of the median sagittal plane of the user's head during use. In this example, the upper side of the opening 1185 is also bent in the posterior direction on either side of the median sagittal plane of the user's head during use.

[0531] The opening 1185 can advantageously provide ventilation and / or heat dissipation benefits, as well as increase versatility, such as by allowing the head mounted display system 1000 with the interfacing structure 1100 attached to be used with a docking station or the like.

[0532] clean

[0533] In some forms, the head mounted display system 1000, or at least a portion thereof, is designed to be used by a single user and cleaned in the user's home, e.g., in soapy water, without the need for specialized disinfecting and sterilizing equipment. Specifically, both the positioning and stabilizing structure 1300 and the interfacing structure 1100 are in direct contact with the user's head and are therefore designed to be cleanable.

[0534] In some other forms, components of the positioning and stabilizing structure 1300 and the interfacing structure 1100 are used in laboratories, clinics, and hospitals, where a single head mounted display may be reused on multiple people or used during medical procedures. In each laboratory, clinic, and hospital, the head mounted display or its associated components may be reprocessed and exposed to processes such as thermal disinfection, chemical disinfection, and sterilization. Therefore, the design of the positioning and stabilizing structure and the interfacing structure may need to be validated for disinfection and sterilization of masks according to ISO 17664.

[0535] Materials that can withstand reprocessing can be selected. For example, strong materials can be used in the positioning and stabilizing structure 1300 to withstand exposure to high concentration disinfectant solutions and agitation with a brush. In addition, some components of the positioning and stabilizing structure are detachable and can be disconnected during use to improve reprocessing efficiency.

[0536] In some instances, the interfacing structure 1100 may come into contact with the user's head during use and may therefore become dirty (e.g., due to sweat). The interfacing structure 1100 may be designed to be detached from the display unit housing 1205 to provide the ability to disassemble it for cleaning and / or replacement. It may be desirable to wash the interfacing structure 1100 without getting the positioning and stabilizing structure 1300 wet. Alternatively or in addition, the positioning and stabilizing structure 1300 may become dirty due to contact with the user's head and may be disassembled for cleaning and / or replacement independently of the interfacing structure 1100. In either case, this may be facilitated by allowing the components to be disconnected for such purpose.

[0537] In some examples, a cover (e.g., composed of fabric, silicone, etc.) can be removably positioned over the interfacing structure and can be removed for cleaning and / or replacement after each use. The cover can allow the interface structure 1100 to remain secured to the display unit housing 1205 and still provide a surface that can be easily cleaned after use.

[0538] In some forms, the overlap of the pad attachment portion 1120 and the pad support flange 1164 may limit the cleaning fluid from contacting the glue 1124 and / or the pad 1130 during the cleaning process.

[0539] External Computer

[0540] 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.

[0541] In some forms, at least some of the processing for the head mounted display system 1000 may be performed by a separate device. The separate device may include a larger and / or more powerful processor that the user cannot comfortably support (e.g., the processor of the separate device may be too heavy for the user to comfortably support on their head).

[0542] Glossary

[0543] For purposes of this technology disclosure, in some forms of the technology, one or more of the following definitions may apply. In other forms of the technology, alternative definitions may apply.

[0621] Structural shape

[0622] Products according to the present technology may include one or more three-dimensional mechanical structures, such as a mask cushion or an impeller. The three-dimensional structure may be defined by two-dimensional surfaces. These surfaces may be distinguished using markings to describe the associated surface orientation, position, function, or some other characteristic. For example, a structure may include one or more of a front surface, a rear surface, an inner surface, and an outer surface. In another example, a seal-forming structure may include a face-contacting (e.g., outer) surface and a separate non-face-contacting (e.g., underside or inner) surface. In another example, a structure may include a first surface and a second surface.

[0623] To facilitate the description of the shape of three-dimensional structures and surfaces, we first consider a cross section through the surface of the structure at a point p. FIG. 3A to FIG. 3E , illustrates an example of a cross section at a point p on a surface, and the resulting plane curve. FIG. 3A to FIG. 3E The outward normal vector at point p is also shown. The outward normal vector at point p points away from the surface. In some examples, we describe the surface from the perspective of an imaginary person standing upright on the surface.

[0624] One-dimensional curvature

[0625] The curvature of a plane curve at p can be described as having a sign (eg, positive, negative) and a magnitude (eg, 1 / radius of a circle that just touches the curve at p).

[0626] Positive curvature: If the curve at point p turns toward the outward normal, the curvature at that point is taken to be positive (if the imaginary person were to leave point p, they would have to be walking uphill). Figure 3A (and Figure 3B Compared with the relatively large positive curvature) and Figure 3B (and Figure 3AThe positive curvature is relatively small compared to the negative curvature.) Such curves are often called concave curves.

[0627] Zero curvature: If the curve at point p is a straight line, the curvature will be zero (if the imaginary person leaves point p, they can walk horizontally without going up or down). Figure 3C .

[0628] Negative curvature: If the curve at point p turns away from the outward normal, then the curvature in that direction at that point will be negative (if the imaginary person were to leave point p, they would have to be walking downhill). Figure 3D (and Figure 3E Compared to the relatively small negative curvature) and Figure 3E (and Figure 3F Such curves are often called convex curves.

[0629] Curvature of a 2D surface

[0630] A description of a shape at a given point on a two-dimensional surface according to the present technology may include multiple normal cross sections. Multiple cross sections may cut the surface in a plane ("normal plane") including an outward normal, and each cross section may be taken in a different direction. Each cross section produces a planar curve with a corresponding curvature. The different curvatures at the point may have the same sign or different signs. Each curvature at the point has an amplitude, such as a relatively small amplitude. FIG. 3A to FIG. 3E The plane curve in can be an example of such multiple cross sections at specific points.

[0631] Principal curvatures and principal directions: The directions of the normal planes where the curvature of the curve takes its maximum and minimum values ​​are called principal directions. FIG. 3A to FIG. 3E In the example of Figure 3A and the minimum curvature occurs at Figure 3E Therefore Figure 3A and Figure 3E is the cross section in the principal direction. The principal curvature at p is the curvature in the principal direction.

[0632] Region of a surface: A set of connected points on a surface. The points in a region can have similar properties, such as curvature or sign.

[0633] Saddle region: A region where the principal curvatures at each point have opposite signs, i.e. one is positive and the other is negative (depending on which way the imaginary person turns, they may be going uphill or downhill).

[0634] Dome region: The region where the principal curvatures at every point have the same sign, e.g. both are positive (a "concave dome") or both are negative (a "convex dome").

[0635] Cylindrical region: A region where one of the principal curvatures is zero (or is zero, for example, within manufacturing tolerances) and the other principal curvature is non-zero.

[0636] Planar region: A surface region where both principal curvatures are zero (or are zero, for example, within manufacturing tolerances).

[0637] Edge of a surface: The boundary or limit of a surface or area.

[0638] Path: In some forms of the present technology, a "path" will be taken to mean a path in the mathematical topological sense, e.g. a continuous spatial curve from f(0) to f(1) on a surface. In some forms of the present technology, a "path" may be described as a route or journey comprising, e.g., a set of points on a surface. (A hypothetical person's path is where they walk on a surface, and is analogous to a garden path).

[0639] Path length: In some forms of the present technology, "path length" will be taken to mean the distance along the surface from f(0) to f(1), i.e., the distance along a path on the surface. There may be more than one path between two points on the surface, and such paths may have different path lengths. (The path length of a hypothetical person would be the distance they would walk along a path on the surface).

[0640] Straight-line distance: Straight-line distance is the distance between two points on a surface, but regardless of the surface. On a planar surface, there will be a path on the surface that has the same path length as the straight-line distance between two points on the surface. On a non-planar surface, there may not be a path that has the same path length as the straight-line distance between two points. (For an imaginary person, straight-line distance would correspond to the distance as a "straight line".

[0641] hole

[0642] A surface may have one-dimensional pores, such as pores defined by a plane curve or a space curve. A thin structure (e.g., a membrane) having pores may be described as having one-dimensional pores. See, e.g. Figure 3F A one-dimensional hole in the surface of the structure shown is defined by a planar curve.

[0643] A structure may have two-dimensional pores, such as pores defined by a surface. For example, an inflatable tire has a two-dimensional pore defined by the inner surface of the tire. In another example, a bladder having a cavity for air or gel may have a two-dimensional pore. In yet another example, a conduit may include a one-dimensional pore (e.g., at its inlet or at its outlet) and a two-dimensional pore defined by the inner surface of the conduit. See also through Figure 3H The two-dimensional pores of the shown structure are defined by the shown surfaces.
