The fastening mechanism may also include a first band 1-116 having a first end 1-142 coupled to a first distal end 1-136 and a second end 1-144 coupled to a second distal end 1-140, and a second band 1-117 extending between the first electronic strap 1-105a and the second electronic strap 1-105b. The straps 1-105a and 1-105b and the band 1-116 may be connected via a connecting mechanism or assembly 1-114. In at least one example, the second band 1-117 includes a first end 1-146 coupled to a first electron strap 1-105a between a first proximal end 1-134 and a first distal end 1-136, and a second end 1-148 coupled to a second electron strap 1-105b between a second proximal end 1-138 and a second distal end 1-140.

[0826] In at least one example, the first and second electronic straps 1-105a-b include plastic, metal, or other structural material that forms the shape of substantially rigid straps 1-105a-b. In at least one example, the first and second bands 1-116, 1-117 are formed from an elastic flexible material, including woven fabric, rubber, etc. The first and second bands 1-116, 1-117 may be flexible to conform to the shape of the user's head when the HMD 1-100 is worn.

[0827] In at least one example, one or more of the first and second electronic straps 1-105a to b may define an internal strap volume and include one or more electronic components disposed within that internal strap volume. In one example, as shown in Figure 1-1A, the first electronic strap 1-105a may include electronic component 1-112. In one example, electronic component 1-112 may include a speaker. In another example, electronic component 1-112 may include a computing component such as a processor.

[0828] In at least one example, the housing 1-150 defines a first forward-facing opening 1-152. The forward display assembly 1-108 is positioned to block the first opening 1-152 from view when the HMD 1-100 is assembled, so the forward-facing opening is labeled with a dotted line at 1-152 in Figure 1-1A. The housing 1-150 may also define a second rearward-facing opening 1-154. The housing 1-150 also defines an internal volume between the first opening 1-152 and the second opening 1-154. In at least one example, the HMD 1-100 includes a display assembly 1-108, which may include a front cover and a display screen (shown in other figures) positioned within or across the front opening 1-152 to block the front opening 1-152. In at least one example, the display screen of display assembly 1-108 has a curvature configured to follow the curvature of the user's face, as well as the display assembly 1-108 as a whole. The display screen of display assembly 1-108 can be curved to complement the features of the user's face and the overall curvature from one side of the face to the other, for example, from left to right and / or from top to bottom when the display unit 1-102 is pressed.

[0829] In at least one example, the housing 1-150 may define a first aperture 1-126 between a first opening 1-152 and a second opening 1-154, and a second aperture 1-130 between the first opening 1-152 and the second opening 1-154. The HMD 1-100 may also include a first button 1-128 disposed in the first aperture 1-126 and a second button 1-132 disposed in the second aperture 1-130. The first and second buttons 1-128 and 1-132 may be pressable through their respective apertures 1-126 and 1-132. In at least one example, the first button 1-126 and / or the second button 1-130 may be a twistable dial and a pressable button. In at least one example, the first buttons 1-126 are pressable and twistable dial buttons, and the second buttons 1-132 are pressable buttons.

[0830] Figure 1-1B shows a rear perspective view of the HMD1-100. The HMD1-100 may include an optical seal 1-110 that extends rearward from the housing 1-150 of the display assembly 1-108 and around the outer periphery of the housing 1-150. The optical seal 1-110 may be configured to extend from the housing 1-150 to the user's face around the user's eyes to block external light from being visible. In one example, the HMD1-100 may include first and second display assemblies 1-120a, 1-120b that are disposed in or within a rearward-facing second opening 1-154 defined by the housing 1-150 and / or disposed within the internal volume of the housing 1-150 and configured to project light through the second opening 1-154. In at least one example, each display assembly 1-120a-b may include respective display screens 1-122a, 1-122b configured to project light backward through a second opening 1-154 toward the user's eyes.

[0831] In at least one example, referring to both Figures 1-1A and 1-1B, the display assembly 1-108 may be a forward-facing display assembly including a display screen configured to project light in a first forward direction, and the rear-facing display screens 1-122a-b may be configured to project light in a second rear direction opposite to the first direction. As described above, the light seal 1-110 may be configured to prevent external light from the HMD 1-100, including light projected by the forward-facing display screen of the display assembly 1-108 shown in the front perspective view of Figure 1-1A, from reaching the user's eyes. In at least one example, the HMD 1-100 may also include a curtain 1-124 that closes a second opening 1-154 between the housing 1-150 and the rear-facing display assemblies 1-120a-b. In at least one example, the curtain 1-124 may be elastic or at least partially elastic.

Similarly, any of the features, components, and / or parts shown and described with reference to Figures 2 to 4, including their arrangement and configuration, may be included, individually or in any combination, in the examples of devices, features, components, and parts shown in Figures 1-1A and 1-1B.

[0833] Figure 1-2 shows an example of an HMD1-200 that includes various parts or components separated according to modularity and the selective coupling of those parts. For example, the HMD1-200 may include a band 1-216 that can be selectively coupled to first and second electronic straps 1-205a, 1-205b. The first fastening strap 1-205a may include a first electronic component 1-212a, and the second fastening strap 1-205b may include a second electronic component 1-212b. In at least one example, the first and second straps 1-205a and 1-205b may be detachably coupled to a display unit 1-202.

[0834] In addition, the HMD1-200 may include an optical seal 1-210 configured to be detachably coupled to a display unit 1-202. The HMD1-200 may also include a lens 1-218 that can be detachably coupled to the display unit 1-202, for example, on first and second display assemblies including a display screen. The lens 1-218 may include a customized prescription lens configured for vision correction. As stated, each component shown in the diagram of Figure 1-2 and described above may be detachably coupled, mounted, reattached, and replaced in order to update or replace parts for different users. For example, bands such as band 1-216, optical seals such as optical seal 1-210, lenses such as lens 1-218, and electronic straps such as straps 1-205a~b may be replaced on a user-by-user basis so that these components are customized to fit and correspond to individual users of the HMD1-200.

[0835] Any of the features, components, and / or parts shown in Figure 1-2, including their arrangement and configuration, may be included, individually or in any combination, in any other example of devices, features, components, and parts shown in Figures 1-1A, 1-1B, and 1-3 to 1-4 and described herein.

[0836] Figure 1-3 shows an example of a display unit 1-306 of an HMD. The display unit 1-306 may include a front display assembly 1-308, a frame / housing assembly 1-350, and a curtain assembly 1-324. The display unit 1-306 may also include a sensor assembly 1-356, a logic board assembly 1-358, and a cooling assembly 1-360, disposed between the frame assembly 1-350 and the front display assembly 1-308. In at least one example, the display unit 1-306 may also include a rear-facing display assembly 1-320, which includes first and second rear-facing display screens 1-322a and 1-322b, disposed between the frame 1-350 and the curtain assembly 1-324.

[0837] In at least one example, the display unit 1-306 may also include a motor assembly 1-362 configured as an adjustment mechanism for adjusting the position of the display screens 1-322a-b of the display assembly 1-320 relative to the frame 1-350. In at least one example, the display assembly 1-320 is mechanically coupled to a motor assembly 1-362 with at least one motor for each display screen 1-322a-b, so that the motors can translate the display screens 1-322a-b to match the interpupillary distance of the user's eyes.

[0838] In at least one example, the display unit 1-306 may include a dial or button 1-328 that is pressable relative to the frame 1-350 and accessible to the user outside the frame 1-350. The button 1-328 may be electronically connected to the motor assembly 1-362 via a controller so that the user can operate the button 1-328 to cause the motors of the motor assembly 1-362 to adjust the position of the display screens 1-322a-b.

[0839] Any of the features, components, and / or parts shown in Figure 1-3, including their arrangement and configuration, may be included, either individually or in any combination, in any other example of devices, features, components, and parts shown in Figures 1-1A to 1-2 and 1-4 and described herein.

[0840] Figure 1-4 shows a diagram of another example of a display unit 1-406 of an HMD device similar to other HMD devices described herein. Display unit 1-406 may include a forward display assembly 1-402, a sensor assembly 1-456, a logic board assembly 1-458, a cooling assembly 1-460, a frame assembly 1-450, a rear-facing display assembly 1-421, and a curtain assembly 1-424.

[0841] Various components, systems, and assemblies shown in Figure 1-4 are described in more detail herein with reference to Figures 1-1A to 1-3 and subsequent figures referenced herein. The display unit 1-406 shown in Figure 1-4 may be assembled and integrated with the fastening mechanisms shown in Figures 1-1A to 1-3, which include other components such as electronic straps, bands, and optical seals, and connecting assemblies.

[0842] Any of the features, components, and / or parts shown in Figure 1-4, including their arrangement and configuration, may be included, individually or in any combination, in any other example of devices, features, components, and parts shown in Figures 1-1A to 1-3 and described herein.

II: Cover glass

[0843] Figure 2.0-1 shows a diagram of the HMD2.0-100, which includes a front cover and display assembly 2.0-102 comprising one or more transparent layers, a display integration assembly, a shroud, and a dust seal. The transparent layers, display assembly, shroud, and dust seal are described in sections II, III, IV, and V below. 2.1: System with a transparent layer

[0844] The transparent layer can be used to form windows in buildings, vehicles, and / or other systems. The transparent layer can also be used to form protective covering layers, such as covering layers for optical components.

[0845] Figure 2.1-1 is a side cross-sectional view of an exemplary system having transparent layers. System 2.1-10 in Figure 2.1-1 has supports such as support 2.1-12 to which one or more transparent layers, such as transparent layer 2.1-14, can be attached. System 2.1-10 may be a building (e.g., support 2.1-12 may include the walls of a building), a vehicle (e.g., support 2.1-12 may be the vehicle body), an electronic device (e.g., support 2.1-12 may be an electronic device housing such as a head-mount housing for a head-mount device), and / or any other suitable system. In configurations where system 2.1-10 is a building or a vehicle, layer 2.1-14 may function as a window. In configurations where system 2.1-10 is an electronic device, layer 2.1-14 may overlap and protect components within the device. For example, layer 2.1-14 may function as a protective cover layer overlapping an optical component. In an exemplary configuration, System 2.1-10 is a portable electronic device (e.g., a mobile phone, head-mounted device, tablet computer, laptop computer, wristwatch, etc.).

[0846] The transparent layer 2.1-14 and the support 2.1-12 can separate the internal region 2.1-16 of system 2.1-10 from the external region 2.1-18. System components can be mounted within the internal region 2.1-16. Layer 2.1-14 may have opposing inner and outer surfaces. The outer surface of layer 2.1-14 may face the external region 2.1-18, and the inner surface of layer 2.1-14 may face the internal region 2.1-16. The surface of layer 2.1-14 may have planar portions and / or curved portions. For example, layer 2.1-14 may have a shape with a curved cross-sectional profile such as shape 2.1-20. In a configuration where layer 2.1-14 is curved, the inner and outer surfaces may be parallel to each other (for example, the thickness of layer 2.1-14 may be constant across layer 2.1-14). If necessary, part or all of the surface of layer 2.1-14 may have composite curvature (a surface that can only be planarized on a plane with strain). The surface area with composite curvature may be bent around both the X and Y axes in Figure 2.1-1.

[0847] Figure 2.1-2 shows how layer 2.1-14 may overlap with components within internal region 2.1-16, such as exemplary components 2.1-20 and 2.1-22. Components 2.1-20 and 2.1-22 may include optical components that emit and / or detect light. For example, component 2.1-22 may be a display that emits visible light passing through layer 2.1-14. This allows an observer in external region 2.1-18 to see an image on the display through layer 2.1-14 (for example, layer 2.1-14 may function as a display cover layer). Components such as component 2.1-20 may include, for example, visible and / or infrared cameras and / or other optical sensors that receive light through layer 2.1-14. By stacking components 2.1-20 and 2.1-22 as shown in Figure 2.1-2, layer 2.1-14 can function as a protective cover layer for components 2.1-20 and 2.1-22.

[0848] During events such as a drop event in which system 2.1-10 suddenly comes into contact with the ground or another hard surface, layer 2.1-14 may be subjected to an undesirable amount of stress. To help improve durability, layer 2.1-14 may be provided with one or more polymer layers. For example, the polymer layer may be used to laminate multiple layers of transparent material together, and / or the polymer layer may be formed on the exposed inner and / or outer surfaces of layer 2.1-14.

[0849] Figure 2.1-3 is a side cross-sectional view of layer 2.1-14. As shown in Figure 2.1-3, layer 2.1-14 may comprise multiple layers of transparent material, such as layers 2.1-40, 2.1-34, 2.1-32, and 2.1-30. In an exemplary configuration, layer 2.1-14 comprises two layers of rigid transparent material and one or more flexible layers attached to the rigid layers. The flexible layers may be, for example, polymer layers that help to increase durability.

[0850] In the example shown in Figure 2.1-3, layer 2.1-34 may be a hard layer, such as a layer of glass (including glass ceramic) or sapphire or other crystalline material. An exemplary configuration in which layer 2.1-34 is a glass layer may be described as an example herein. Layer 2.1-34 may be formed from alumina silicate glass or other glass material and may be optionally chemically strengthened using an ion exchange chemical strengthening process that places the surface of layer 2.1-34 under compression relative to the core of layer 2.1-34. Layer 2.1-34 may have sufficient thickness to provide layer 2.1-14 with some or all of its structural strength, and therefore layer 2.1-34 may also be called a structural layer, structural transparent layer, or structural glass layer. Layers 2.1-34 may have thicknesses of, for example, 700 microns, at least 400 microns, at least 500 microns, at least 600 microns, less than 1200 microns, less than 1000 microns, less than 900 microns, less than 800 microns, 400 to 1200 microns, 400 to 1100 microns, 400 to 1000 microns, 400 to 800 microns, and / or other suitable thicknesses.

[0851] One or more polymer layers may be attached to layer 2.1-34. In an exemplary configuration, polymer layer 2.1-40 is attached to the inner surface 2.1-42 of layer 2.1-34. Layer 2.1-40 may comprise a first layer, such as layer 2.1-38, and a second layer, such as layer 2.1-36. Layer 2.1-38 may be a polymer film (e.g., a polycarbonate, polyethylene terephthalate film, or other polymer film) and may have a thickness of 50 microns, 10 to 250 microns, 25 to 100 microns, at least 20 microns, less than 200 microns, less than 150 microns, or other preferred thicknesses. Layer 2.1-36 may be a polymer layer, such as a layer of polymer adhesive (e.g., epoxy, acrylic adhesive, curing liquid adhesive, pressure-sensitive adhesive, and / or other adhesive) used to attach layer 2.1-38 to layer 2.1-34, and may have a thickness of 100 microns, 20 to 500 microns, at least 30 microns, less than 250 microns, less than 300 microns, or other suitable thicknesses.

[0852] If desired, an additional polymer layer, such as polymer layer 2.1-32, may be attached to the upper outer surface 1.3-44 of layer 2.1-34. Layer 2.1-32 may be formed from an elastomer polymer or other flexible polymer material. Examples of materials that may be used to form polymer layer 2.1-32 include polyvinyl butyral and ethylene vinyl acetate. Other polymers may be used to form layer 2.1-32 as needed. Layer 2.1-32 may be the outermost layer of the material of layer 2.1-14 (for example, the outer surface of layer 2.1-32 may be exposed to region 2.1-18), or layer 2.1-32 may be covered with a harder outer layer.

[0853] As shown in Figure 2.1-3, a thin hard layer, such as the outer layer 2.1-30, can be attached to layer 2.1-34 using layer 2.1-32, which may also be called an elastomer polymer layer or polymer intermediate layer. The thickness of layer 2.1-32 may be 50 microns, 25-100 microns, at least 20 microns, at least 40 microns, at least 50 microns, less than 400 microns, 25-400 microns, less than 300 microns, less than 200 microns, 20-200 microns, 50-400 microns, or other suitable thickness. Layer 2.1-30 can be formed from glass (including glass ceramic), crystalline materials such as sapphire, or a hard polymer (e.g., cured acrylic). The thickness of layer 2.1-30 is preferably less than the thickness of layer 2.1-34 in order to help minimize the weight of layer 2.1-14.

[0854] In an exemplary configuration, layer 2.1-30 is formed as a separate layer (e.g., a glass layer separate from layer 2.1-34) attached to layer 2.1-34 by laminating layers 2.1-30 and 2.1-34 together using polymer layer 2.1-32. The thickness of layer 2.1-30 in this type of configuration may be at least 50 microns, at least 75 microns, at least 100 microns, less than 300 microns, less than 250 microns, less than 200 microns, less than 150 microns, less than 100 microns, 50 to 200 microns, 25 to 300 microns, 50 to 150 microns, or other suitable thickness (e.g., a thickness that provides the outermost surface of layer 2.1-14 with sufficient hardness to resist scratching). In addition to resisting scratching, including a hard outer layer such as layer 2.1-30 relative to layer 2.1-14 helps to increase the strength of layer 2.1-14, thereby allowing for a reduction in the thickness of layer 34. In this type of configuration, to help match the curvature of layers 2.1-30 and 2.1-34, layers 2.1-30 and 2.1-34 may be formed into the desired shape using molding operations (e.g., glass molding), machining and / or polishing operations, etching (wet and / or dry chemical etching), and / or other suitable molding operations.

[0855] In some embodiments, layers 2.1-30 may be deposited as a coating on layers 2.1-32. For example, a hard inorganic dielectric layer (e.g., silicon nitride, silicon oxynitride, zirconia, alumina, and / or a glass coating formed from other hard dielectric coatings deposited by physical vapor deposition, or a glass coating formed from an inorganic dielectric based on silicon oxide deposited by sol-gel deposition techniques) can be deposited using deposition techniques such as physical vapor deposition and sol-gel deposition. The thickness of this coating may be sufficient for the coating to improve durability (e.g., to help prevent scratching of layers 2.1-32). For example, layers 2.1-30 may have a thickness of at least 20 microns, at least 25 microns, at least 35 microns, and / or other preferred thicknesses. If desired, a liquid polymer (e.g., liquid acrylic) can be deposited and cured to form an acrylic hard coat (e.g., layer 2.1-30 may be a polymer hard coat that is harder than layer 2.1-32 and therefore helps to resist scratching). 2.2: Systems with displays and sensors

[0856] Figure 2.2-1 is a side view of an exemplary head-mounted electronic device. As shown in Figure 2.2-1, the head-mounted device 2.2-10 may include a head-mounted support structure 2.2-26. The support structure 2.2-26 may have walls or other structures that separate an internal region of the device 2.2-10, such as an internal region 2.2-42, from an external region surrounding the device 2.2-10, such as an external region 2.2-44. Electrical components 2.2-40 (e.g., integrated circuits, sensors, control circuits, light-emitting diodes, lasers, and other light-emitting devices, other control circuits, and input / output devices) may be mounted on printed circuits and / or other structures within the device 2.2-10 (e.g., within the internal region 2.2-42).

[0857] To present images to the user for viewing through an eyebox such as eyebox 2.2-34, device 2.2-10 may include a rear display such as display 2.2-14R and a lens such as lens 2.2-38. These components can be mounted within an optical module such as optical module 2.2-36 (e.g., lens barrel) to form the left and right optical systems. For example, there may be a left rear display for presenting an image to the user's left eye through the left lens in the left eyebox, and a right rear display for presenting an image to the user's right eye in the right eyebox. The user's eyes are located within the rear eyebox 34 of device 2.2-10 when the structure 2.2-26 is positioned against the outer surface of the user's face (face 2.2-30).

[0858] The support structure 2.2-26 may include a main support structure such as a main housing portion 2.2-26M (sometimes called the main portion). The main housing portion 2.2-26M may extend from the front side F of the device 2.2-10 to the rear side R opposite to the device 2.2-10. At the rear side R, the main housing portion 2.2-26M may have a cushioning structure to enhance user comfort when the portion 2.2-26M is placed against the face 2.2-30. If necessary, the support structure 2.2-26 may include an optional head strap such as a strap 2.2-26B, and / or other structures that enable the device 2.2-10 to be attached to the user's head.

[0859] Device 2.2-10 may have a publicly visible forward-facing display, such as a display 2.2-14F, mounted on the front side F of the main housing portion 2.2-26M. The display 2.2-14F may be visible to the user when the user is not wearing the device 2.2-10, and / or may be visible to others in the vicinity of the device 2.2-10. The display 2.2-14F may, for example, be seen on the front side F of the device 2.2-10 by an external observer, such as observer 2.2-50, who is looking at the device 2.2-10 in direction 2.2-52.

[0860] A schematic diagram of an exemplary system that may include a head-mounted device is shown in Figure 2.2-2. As shown in Figure 2.2-2, system 2.2-8 may include one or more electronic devices 2.2-10. Devices 2.2-10 may include a head-mounted device (e.g., device 2.2-10 in Figure 2.2-1), accessories such as a controller and headphones, computing equipment (e.g., a cellular phone, a tablet computer, a laptop computer, a desktop computer, and / or remote computing equipment that supplies content to the head-mounted device), and / or other devices that communicate with each other.

[0861] Each electronic device 2.2-10 may have a control circuit 2.2-12. The control circuit 2.2-12 may include storage and processing circuits that control the operation of the device 2.2-10. The circuit 2.2-12 may include storage such as a hard disk drive, non-volatile memory (e.g., electrically programmable read-only memory configured to form a solid-state drive), or volatile memory (e.g., static or dynamic random-access memory). The processing circuits of the control circuit 2.2-12 may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, graphics processing units, application-specific integrated circuits, and other integrated circuits. Software code is stored on the storage within the circuit 2.2-12 and executed on the processing circuits within the circuit 2.2-12 to perform control operations of the device 2.2-10 (e.g., data acquisition operations, operations including the adjustment of components of the device 2.2-10 using control signals, etc.). The control circuit 2.2-12 may include wired communication circuits and wireless communication circuits. For example, control circuit 2.2-12 may include wireless transceiver circuits such as cellular telephone transceiver circuits, wireless local area network transceiver circuits (e.g., WiFi® circuits), millimeter-wave transceiver circuits, and / or other wireless communication circuits.

[0862] During operation, communication between electronic devices can be supported using the communication circuits of devices within System 2.2-8 (for example, the communication circuit of the control circuit 2.2-12 of device 2.2-10). For example, one electronic device can transmit video data, audio data, control signals, and / or other data to another electronic device within System 2.2-8. Electronic devices within System 2.2-8 can communicate over one or more communication networks (e.g., the Internet, a local area network, etc.) using wired and / or wireless communication circuits. Communication circuits can be used to enable device 2.2-10 to receive data from and / or provide data to external devices (e.g., portable devices such as tethered computers, handheld devices, or laptop computers, online computing devices such as remote servers or other remote computing equipment, or other electrical equipment).

[0863] Each device 2.2-10 in system 2.2-8 may include an input / output device 2.2-22. The input / output device 2.2-22 can be used to enable a user to provide user input to device 2.2-10. The input / output device 2.2-22 may also be used to collect information about the environment in which device 2.2-10 is operating. Output components within device 2.2-22 can enable device 2.2-10 to provide output to a user and can be used for communication with external electrical equipment.

[0864] As shown in Figure 2.2-2, the input / output device 2.2-22 may include one or more displays, such as display 2.2-14. Display 2.2-14 may include a rear display, such as display 2.2-14R in Figure 2.2-1. Device 2.2-10 may include left and right components, such as left and right scanning mirror display devices or other image projectors, liquid crystal on silicon display devices, digital mirror devices or other reflective display devices, left and right display panels based on light-emitting diode pixel arrays (e.g., organic light-emitting displays having polymer or semiconductor substrates, or display devices based on pixel arrays formed from crystalline semiconductor light-emitting diode dies), liquid crystal display panels, and / or other left and right display devices that provide images to left and right eye boxes for viewing by the user's left and right eyes, respectively. Such display components (e.g., organic light-emitting displays having flexible polymer substrates, or displays based on pixel arrays formed from crystalline semiconductor light-emitting diode dies on flexible substrates) can also be used to form front displays (sometimes called forward-facing displays, front displays, or publicly visible displays) for devices 2.2-10, such as the front display 2.2-14F in Figure 2.2-1.

[0865] During operation, displays 2.2-14 (e.g., displays 2.2-14R and / or 2.2-14F) may be used to display visual content for the user of device 2.2-10 (e.g., still images and / or videos, including photographs and pass-through videos from camera sensors, text, graphics, movies, games, and / or other visual content). The content presented on display 2.2-14 may include, for example, virtual objects and other content provided to display 2.2-14 by control circuit 2.2-12. This virtual content may also be called computer-generated content. Computer-generated content may be displayed when there is no real-world content, or it may be combined with real-world content. In some configurations, real-world images may be captured by a camera (e.g., a front-facing camera, sometimes called a front camera), and computer-generated content may be electronically overlaid on a portion of the real-world image (e.g., when device 2.2-10 is a pair of virtual reality goggles).

[0866] The input / output circuit 2.2-22 may include a sensor 2.2-16. Examples of sensors 2.2-16 include a three-dimensional sensor (for example, a three-dimensional image sensor such as a structured light sensor that emits a light beam and uses a two-dimensional digital image sensor to collect image data for a three-dimensional image from dots or other light spots generated when a target is illuminated by the light beam), a binocular three-dimensional image sensor that collects three-dimensional images using two or more cameras in a binocular imaging configuration, a three-dimensional lidar (light detection and ranging (LIDAR) sometimes called a time-of-flight camera or three-dimensional time-of-flight camera) Examples of sensors include: (ranging)) sensors, three-dimensional high-frequency sensors, or other sensors that collect three-dimensional image data), cameras (e.g., two-dimensional infrared and / or visible digital image sensors), eye-tracking sensors (e.g., eye-tracking systems based on image sensors, and, if necessary, light sources that emit one or more light beams that are tracked using the image sensor after being reflected from the user's eye), touch sensors, capacitive proximity sensors, light-based (optical) proximity sensors, other proximity sensors, force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors, etc.), sensors such as switch-based contact sensors, gas sensors, pressure sensors, humidity sensors, magnetic sensors, audio sensors (microphones), ambient light sensors, flicker sensors that collect temporal information about ambient lighting conditions such as the presence of time-varying ambient light related to artificial lighting, microphones for collecting voice commands and other voice inputs, sensors configured to collect information about motion, position, and / or orientation (e.g., accelerometers, gyroscopes, compasses, and / or inertial measurement units that include all of these sensors or a subset of one or two of these sensors), and / or other sensors.

[0867] User input and other information may be collected using sensors and other input devices within input / output device 2.2-22. Optionally, input / output device 2.2-22 may include other devices 2.2-24 such as tactile output devices (e.g., vibration components), light-emitting diodes, lasers, and other light sources (e.g., light-emitting devices that emit light to illuminate the environment surrounding device 2.2-10 when ambient light levels are low), speakers such as ear speakers for generating audio output, circuits for receiving wireless power, circuits for wirelessly transmitting power to other devices, batteries and other energy storage devices (e.g., capacitors), joysticks, buttons, and / or other components.

[0868] As described in relation to Figure 2.2-1, the electronic device 2.2-10 may have a head-mount support structure (e.g., a head-mount housing structure such as a housing wall or strap) such as a head-mount support structure 2.2-26. The head-mount support structure may be configured to be attached to the user's head (e.g., relative to the user's face, covering the user's eyes) during the operation of the device 2.2-10, and can support a display 2.2-14, a sensor 2.2-16, other components 2.2-24, other input / output devices 2.2-22, and a control circuit 2.2-12 (see, for example, components 2.2-40 and optical module 2.2-36 in Figure 2.2-1).

[0869] Figure 2.2-3 is a front view of device 2.2-10 in an exemplary configuration in which device 2.2-10 has a publicly visible display such as a front display 2.2-14F. As shown in Figure 2.2-3, the support structure 2.2-26M of device 2.2-10 may have right and left parts such as parts 2.2-26R and 2.2-26L, which are joined by a nose bridge portion interposed between parts such as part 2.2-26NB. Part 2.2-26NB may have a curved outer surface such as a nose bridge surface 2.2-90 configured to receive and rest on the user's nose in order to help support the main housing portion 2.2-26M on the user's head.

[0870] The display 2.2-14F may have an active area such as an active area AA configured to display an image, and a non-active area IA that does not display an image. The contour of the active area AA may be rectangular, a rectangle with rounded corners, and may have teardrop-shaped portions on the left and right sides of the device 2.2-10, and may have a shape with straight edges, a shape with curved edges, a shape with periphery having both straight and curved portions, and / or other preferred contours. As shown in Figure 2.2-3, the active area AA may have a curved recess in the nose bridge portion 2.2-26NB of the main housing portion 2.2-26. The presence of a nose-shaped recess in the active area AA can help to fit the active area AA within the available space of the housing portion 2.2-26M without excessively limiting the size of the active area AA.

[0871] The active area AA includes an array of pixels. The pixels may be, for example, light-emitting diode pixels formed from thin-film organic light-emitting diodes or crystalline semiconductor light-emitting diode dies (sometimes called microlight-emitting diodes) on a flexible display panel substrate. Configurations in which display 2.2-14F uses other display technologies may also be used as needed. Exemplary configurations in which display 2.2-14 is formed from a light-emitting diode display, such as an organic light-emitting diode display, formed on a flexible substrate (for example, a substrate formed from a bendable layer of polyimide or a sheet of another flexible polymer), may also be described as examples herein. The pixels of the active area AA may be formed on a display device such as the display panel 2.2-14P (e.g., a flexible organic light-emitting diode display panel) shown in Figure 2.2-3. In some configurations, the contour of panel 2.2-14P may have a periphery including straight segments or a combination of straight and curved segments. Configurations may also be used in which the entire contour of panel 2.2-14P is characterized by a curved periphery.

[0872] Display 2.2-14F may have inactive areas, such as an inactive area IA, which has no pixels and does not display an image. The inactive area IA may form an inactive boundary region extending along one or more portions of the periphery of the active area AA. In the exemplary configuration of Figure 2.2-3, the inactive area IA has a ring shape surrounding the active area AA. In this type of configuration, the width of the inactive area IA may be relatively constant, and the inner and outer edges of area IA may be characterized by straight and / or curved segments, or curved along their entire length. For example, the periphery of the outer edge of area IA (e.g., of display 2.2-14F) may have a curved contour extending parallel to the curved edge of the active area AA.

[0873] In some configurations, device 2.2-10 can operate in conjunction with other devices in system 2.2-8 (e.g., wireless controllers and other accessories). These accessories may have magnetic sensors that sense the direction and strength of a magnetic field. Device 2.2-10 may have one or more electromagnets configured to emit a magnetic field. The magnetic field can be measured by wireless accessories near device 2.2-10, so that the accessories can determine their orientation and position relative to device 2.2-10. This allows the accessories to function as wireless controllers, as they can wirelessly provide device 2.2-10 with real-time information about their current position, orientation, and movement. Accessories may include wearable devices, devices to be handled, and other input devices.

[0874] In an exemplary configuration, device 2.2-10 may have a coil such as exemplary coil 2.2-54 extending around the outer periphery of display 2.2-14F (e.g., under the inactive area IA or other parts of display 2.2-14F). Coil 2.2-54 may have any preferred number of windings (e.g., 1 to 10, at least 2, at least 5, at least 10, 10 to 50, less than 100, less than 25, less than 6, etc.). These windings may be formed from metal traces on a substrate, from wires, and / or from other conductive wires. During operation, control circuit 2.2-12 may supply an alternating current (AC) drive signal to coil 2.2-54. The drive signal may have a frequency of (for example) at least 1 kHz, at least 10 kHz, at least 100 kHz, at least 1 MHz, less than 10 MHz, less than 3 MHz, less than 300 kHz, or less than 30 kHz. When AC current flows through coil 2.2-54, a corresponding magnetic field is generated near device 2.2-10. An electronic device, such as a wireless controller with a magnetic sensor located near device 2.2-10, can use the magnetic field as a reference so that it can determine its orientation, position, and / or motion while the wireless controller is being moved relative to device 2.2-10 and provide input to device 2.2-10.

[0875] As an example, consider a handheld wireless controller used to control the operation of device 2.2-10. During operation, device 2.2-10 radiates a magnetic field using coil 2.2-54. As the handheld wireless controller is moved, the controller's magnetic sensor can monitor the controller's location and movement relative to device 2.2-10 by monitoring the strength, direction, and changes in strength and / or direction of the magnetic field radiated by coil 2.2-54 as the controller is moved through the air by the user. The electronic device can then wirelessly transmit information about the controller's location and orientation to device 2.2-10. In this way, the handheld controller, wearable controller, or other external accessory can be operated by the user to provide air gestures, pointing inputs, steering inputs, and / or other user inputs to device 2.2-10.

[0876] Device 2.2-10 may have components such as optical components (e.g., the optical sensor among the sensors 2.2-16 in Figure 2.2-2). These components may be mounted at any suitable location on the head-mount support structure 2.2-26 (e.g., on the head strap 2.2-26B, on the main housing portion 2.2-26M, etc.). The optical components and other components may be mounted facing backward (e.g., when mounted on the rear surface of device 2.2-10), laterally (e.g., left or right), downward or upward, forward of device 2.2-10 (e.g., when mounted on the front surface of device 2.2-10), in any combination of these directions (e.g., forward, right, and downward), and / or in other suitable orientations. In an exemplary configuration, at least some of the components of device 2.2-10 are mounted facing forward (and optionally laterally and / or upward and downward). For example, forward-facing cameras for pass-through video may be mounted on the left and right sides of the front of device 2.2-10 in a configuration where the cameras are slightly branched along the horizontal dimension, and the fields of view of these cameras overlap to some extent while capturing wide-angle images of the environment in front of device 2.2-10. The captured images may, if necessary, include portions of the user's surroundings below, above, and to the sides of the area directly in front of device 2.2-10.

[0877] To help conceal components such as optical components from view from the outside of device 2.2-10, it may be desirable to cover some or all of the components with a decorative cover structure. The cover structure may include transparent portions (e.g., optical component windows) characterized by sufficient light transmittance to allow the overlapping optical components to function satisfactorily. For example, an ambient light sensor may be covered with a layer that appears opaque to an external observer to help conceal the ambient light sensor from view, but allows sufficient ambient light to pass through the ambient light sensor for it to perform satisfactory ambient light measurements. As another example, an optical component that emits infrared light may be superimposed with a visually opaque material that is transparent to infrared light.

[0878] In an exemplary configuration, the optical components for device 2.2-10 may be mounted within the inactive area IA in Figure 2.2-3, and the decorative cover structure may be formed in a ring shape overlapping the optical components within the inactive area IA. The decorative cover structure may be formed from ink, polymer structures, metal-containing structures, other materials, and / or combinations of these materials. In an exemplary configuration, the decorative cover structure may be formed from a ring-shaped member having a footprint that matches the footprint of the inactive area IA. For example, if the active area AA has left and right portions having a teardrop shape, the ring-shaped member may have curved edges that follow the curved outer perimeter of the teardrop-shaped portion of the active area AA. The ring-shaped member may be formed from one or more polymer structures (for example, the ring-shaped member may be formed from a polymer ring). Since the ring-shaped member can help to conceal the overlapping components from view, the ring-shaped member is sometimes called a shroud or ring-shaped shroud member. The appearance of the shroud or other decorative cover structure may be characterized by achromatic colors (white, black, or gray) or non-chromatic colors (e.g., blue, red, green, gold, rose gold, etc.).

[0879] Display 2.2-14F may have a protective display cover layer, if necessary. The cover layer may overlap the active area AA and the inactive area IA (for example, the entire front surface of device 2.2-10 as viewed from direction 2.2-52 in Figure 2.2-1 may be covered by the cover layer). The cover layer, sometimes called a housing wall or transparent housing wall, may have a rectangular contour, a contour with a teardrop portion, an elliptical contour, or other shapes with curved and / or straight edges.

[0880] The cover layer can be formed from transparent materials such as glass, polymers, transparent crystalline materials such as sapphire, transparent ceramics, other transparent materials, and / or combinations thereof. As an example, a protective display cover layer for display 2.2-14F may be formed from safety glass (e.g., laminated glass including a transparent glass layer with a laminated polymer film). An optional coating layer may be applied to the surface of the display cover layer. If necessary, the display cover layer may be chemically strengthened (e.g., using an ion exchange process to create an outer layer of material under compressive stress that can withstand scratches). In some configurations, the display cover layer may be formed from a stack of two or more material layers (e.g., a first structural glass layer and a second structural glass layer, a glass layer, or a rigid polymer layer bonded to another rigid polymer layer) to improve the performance of the cover layer.

[0881] In the active area AA, the display cover layer may overlap the pixels of the display panel 2.2-14P. The display cover layer in the active area AA is preferably transparent so that the image presented on the display panel 2.2-14P can be viewed. In the inactive area IA, the display cover layer may overlap a ring-shaped shroud or other decorative cover structure. The shroud and / or other cover structure (e.g., an opaque ink coating on the inner surface of the display cover layer and / or structure) may be sufficiently opaque to help conceal some or all of the optical components in the inactive area IA from view. Windows may be provided in the shroud or other decorative cover structure to help ensure that the optical components on which these structures overlap function satisfactorily. The windows may be formed from holes, from areas of the shroud or other decorative cover structure that are locally thinned to increase light transmission, from window members having desired light transmission properties inserted into a fitting opening in the shroud, and / or from other shroud window structures.

[0882] In the example shown in Figure 2.2-3, device 2.2-10 includes optical components such as (as an example) optical components 2.2-60, 2.2-62, 2.2-64, 2.2-66, 2.2-68, 2.2-70, 2.2-72, 2.2-74, 2.2-76, 2.2-78, and 2.2-80. Each of these optical components (e.g., an optical sensor selected from sensor 2.2-16 in Figure 2.2-2, a light-emitting device, etc.) may be configured to detect light and, if necessary, emit light (e.g., ultraviolet light, visible light, and / or infrared light).

[0883] In an exemplary configuration, optical component 2.2-60 can sense ambient light (e.g., visible ambient light). In particular, optical component 2.2-60 may have a photodetector that senses changes in ambient light intensity as a function of time. For example, if the user is operating in an environment with an artificial light source, the light source may emit light at a frequency associated with its wall power supply (e.g., a 60 Hz AC mains power supply). The photodetector of component 2.2-60 can sense that the artificial light from the artificial light source is characterized by a 60 Hz intensity fluctuation. The control circuit 2.2-12 can use this information to adjust the clock or other timing signals associated with the operation of the image sensor in device 2.2-10 to help avoid undesirable interference between the light source frequency and the frame rate or other frequencies associated with the image capture operation. The control circuit 2.2-12 can also use measurements from component 2.2-60 to help identify the presence and type of artificial lighting present. In this way, the control circuit 2.2-12 can detect the presence of light, such as fluorescent lamps or other light with known non-ideal color characteristics, and can perform corrective color cast adjustment (e.g., white point adjustment) for color-sensitive components such as cameras and displays. Since the optical component 2.2-60 can measure fluctuations in light intensity, component 2.2-60 is sometimes called a flicker sensor or ambient light frequency sensor.

[0884] Optical component 2.2-62 may be an ambient light sensor. The ambient light sensor may include one or more photodetectors. In a single photodetector configuration, the ambient light sensor may be a monochromator that measures ambient light intensity. In a multi-photodetector configuration, each photodetector may have superimposed optical filters that pass through different wavelength bands (e.g., different visible and / or infrared passbands). The optical filter passbands may overlap at their edges. This allows component 2.2-62 to function as a color ambient light sensor that measures both ambient light intensity and ambient light color (e.g., by measuring the color coordinates of the ambient light). During the operation of device 2.2-10, the control circuit 2.2-12 may take action based on the measured ambient light intensity and color. For example, the white point of a display or image sensor may be adjusted based on the measured ambient light color, or the color of another display or image sensor may be adjusted. The intensity of the display may be adjusted based on the light intensity. For example, the brightness of display 2.2-14F may be increased under bright ambient lighting conditions to improve the visibility of images on the display, and the brightness of display 2.2-14F may be reduced under dim lighting conditions to conserve power. Image sensor operation and / or light source operation may also be adjusted based on ambient light readings.

[0885] Optical components within the active area IA may also include components along the sides of device 2.2-10, such as components 2.2-80 and 2.2-64. Optical components 2.2-80 and 2.2-64 may be pose-tracking cameras used to help monitor the orientation and motion of device 2.2-10. Components 2.2-80 and 2.2-64 may also be visible light cameras (and / or cameras that sense visible and infrared wavelengths) and, together with an inertial measurement unit, can form a visual inertial odometry (VIO) system.

[0886] Optical components 2.2-78 and 2.2-66 may be visible light cameras that capture real-time images of the environment surrounding device 2.2-10. Sometimes called scene cameras or pass-through video cameras, these cameras can capture video that is displayed in real time on display 2.2-14R for the user to see when the user's eyes are positioned inside the rear eye box 2.2-34 of device 2.2-10. In this way, by displaying pass-through images (pass-through video) to the user, real-time information about the user's surroundings can be provided to the user. If necessary, virtual content (e.g., computer-generated images) may be overlaid on top of parts of the pass-through video. Device 2.2-10 can also operate in a non-pass-through video mode, where components 2.2-78 and 2.2-66 are turned off, and the user is provided with only other virtual content that does not include movie content, game content, and / or real-time real-world images.

[0887] The input / output device 2.2-22 of device 2.2-10 can collect user input used to control the operation of device 2.2-10. For example, the microphone within device 2.2-10 can collect voice commands. Buttons, touch sensors, force sensors, and other input devices can collect user input from the user's fingers or other external objects in contact with device 2.2-10. In some configurations, it may be desirable to monitor the user's hand gestures or the movements of other user body parts. This allows the location of the user's hands or other body parts to be replicated in the game or other virtual environment, and the user's hand movements can function as hand gestures (air gestures) to control the operation of device 2.2-10. User input, such as hand gesture input, can be captured using cameras operating in visible and infrared wavelengths, such as tracking cameras (e.g., optical components 2.2-76 and 2.2-68). Such tracking cameras can also track reference points and other recognizable features on the controllers and other external accessories (additional devices 2.2-10 in system 2.2-8) while these controllers are being used to control the operation of device 2.2-10. If necessary, the tracking camera can help determine the position and orientation of a handheld or wearable controller, sensing its location and orientation by measuring the magnetic field generated by coil 2.2-54. Thus, the use of tracking cameras can help track hand movements and controller movements used to move pointers and other virtual objects displayed to the user, and otherwise help control the operation of device 2.2-10.

[0888] The tracking camera can operate satisfactorily in the presence of sufficient ambient light (e.g., bright visible ambient illumination conditions). In dim environments, auxiliary illumination can be provided by auxiliary light sources such as auxiliary infrared light sources (e.g., optical components 2.2-82 and 2.2-84). Each infrared light source may include one or more light-emitting devices (light-emitting diodes or lasers), each configured to provide a fixed and / or maneuverable beam of infrared light that serves as auxiliary illumination for the tracking camera. If necessary, the infrared light sources may be turned off in bright ambient illumination conditions (e.g., using the ambient light sensing capability of optical component 2.2-82) and turned on in response to the detection of dim ambient light.

[0889] The three-dimensional sensors within device 2.2-10 may be used to perform biometric identification operations (e.g., facial recognition for authentication), to determine the three-dimensional shape of objects in the user's environment (e.g., to map the user's environment so that a matching virtual environment can be created for the user), and / or to collect three-dimensional content during the operation of device 2.2-10. As an example, optical components 2.2-74 and 2.2-70 may be three-dimensional structured light imaging sensors. Each three-dimensional structured light imaging sensor may have one or more light sources that provide structured light (e.g., a dot projector that projects an array of infrared dots onto the environment, a structured light source that generates a grid of lines, or other structured light components that emit structured light). Each three-dimensional structured light imaging sensor may also include a light source (e.g., a light-emitting diode or laser that emits a broad beam of infrared light). Using floodlighting and structured lighting, optical components 2.2-74 and 2.2-70 can capture facial images, images of objects in the environment surrounding device 2.2-10, and the like.

[0890] Optical component 2.2-72 may be an infrared three-dimensional time-of-flight camera that uses time-of-flight measurement for emitted light to collect three-dimensional images of objects in the environment surrounding device 2.2-10. Component 2.2-72 may have a longer range and narrower field of view than the three-dimensional structured optical cameras of optical components 2.2-74 and 2.2-70. The operating range of component 2.2-72 may be (for example) 30cm to 7m, 60cm to 6m, 70cm to 5m, or other preferred operating ranges.

[0891] Figure 2.2-4 is a top view of device 2.2-10 in an exemplary configuration in which the display 2.2-14F and the main housing portion 2.2-26M are configured to curve along the curved surface of the user's face (curved face surface 2.2-30). In particular, the rear surface 2.2-96 of the housing portion 2.2-26M of device 2.2-10 can have a curved shape bent around axis 2.2-98 (for example, an axis parallel to the vertical Z-axis in the example in Figure 2.2-4). By smoothly wrapping the housing portion 2.2-26M around the curved surface of the user's head, comfort when wearing device 2.2-10 can be enhanced.

[0892] As shown in Figure 2.2-4, the display 2.2-14F and other structures on the front of device 2.2-10 may have a protective cover layer, such as a display cover layer 2.2-92 (for example, the front portion of housing portion 2.2-26M, which may also be called the front housing wall, transparent dielectric housing wall, or dielectric housing member). In some embodiments, the display cover layer 2.2-92 may include an area characterized by a curved surface that can be planarized into a distortion-free plane (sometimes called a developable surface or a curved surface without composite curvature). The display cover layer 2.2-92 may also include an area characterized by composite curvature (for example, a surface that can only be planarized into a distortion-containing plane, sometimes called an indeformable surface).

[0893] In the active area AA of display 2.2-14F, the cover layer 2.2-92 overlaps the array of pixels P in the display panel 2.2-14P. In the inactive area IA, the cover layer 2.2-92 does not overlap any pixels, but may overlap optical components such as the optical components shown in Figure 2.2-3. To help reduce the size and weight of device 2.2-10, display 2.2-14F may have a curved shape that wraps around the front of the user's head, parallel to the face 2.2-30 and parallel to the curved rear surface 2.2-96 of housing portion 2.2-26M. For example, display panel 2.2-14P may have a flexible substrate that allows panel 2.2-14P to bend around a bending axis 2.2-94 (e.g., a bending axis parallel to the Z-axis in the example in Figure 2.2-4). In the active area AA of display 2.2-14F, the display cover layer 2.2-92 may have an inner surface with a curved cross-sectional profile that conforms to the curved display panel 2.2-14P, and a corresponding curved outer surface. In the inactive area IA, the display cover layer 2.2-92 may also be curved (e.g., having a tighter bending radius and greater curvature than in the active area AA). If necessary, a polymer layer (sometimes called a shroud canopy or polymer member) may be interposed between the display cover layer 2.2-92 and the display panel 2.2-14P. The polymer layer may be separated from the pixels of panel 2.2-14P by voids, and may be separated from the inner surface of the display cover layer 2.2-92 by voids (for example).

[0894] Figure 2.2-5A is a side cross-sectional view of display 2.2-14F as seen from the X direction. As shown in Figure 2.2-5A, the cross-sectional profile of display panel 2.2-14P (in a plane parallel to the YZ plane) may be straight rather than curved in the exemplary configuration. This can help prevent wrinkles or other distortions in the flexible substrate material of display panel 2.2-14P when display panel 2.2-14P is bent around the bending axis 2.2-94 and wraps around the curved surface of the user's face. In this example, display panel 2.2-14P may have a developable surface (e.g., a surface with a curved cross-sectional profile but without any composite curvature). Panel 2.2-14P in Figure 2.2-5A may be attached to the inner surface of layer 2.2-92 (e.g., with adhesive). In this scenario, the inner surface of layer 2.2-92 may be a developable surface that mates with the outward-facing developable surface of panel 2.2-14P. The corresponding outer surface of layer 2.2-92 within the active area AA may be a developable surface or a surface with composite curvature. In the inactive area IA, layer 2.2-92 may have an inner and / or outer surface with composite curvature, and / or the inner and / or outer surface may be a developable surface. If necessary, the entire outer surface of layer 2.2-92 may have composite curvature (in both the active area AA and the inactive area IA), the inner surface of layer 2.2-92 in the active area AA may be a developable surface to which panel 2.2-14P is laminated with adhesive, and the inner surface of layer 2.2-92 in the inactive area IA may have composite curvature and / or be a developable surface.

[0895] Another exemplary configuration of display 2.2-14F is shown in Figure 2.2-5B. As shown in the side section view of Figure 2.2-5B, the display cover layer 2.2-92 may, if necessary, have a curved cross-sectional profile throughout the layer 2.2-92. In this type of configuration, the surface of the inactive area IA of the display cover layer 2.2-92 may have a composite curvature, and the active area AA of the display cover layer 2.2-92 may have a composite curvature (for example, layer 2.2-92 may not include any area having a developable surface). A polymer layer, such as polymer layer 2.2-130, sometimes called a shroud or shroud canopy, may be interposed between the inner surface of the display cover layer 2.2-92 and the opposing outer surface of the display panel 2.2-14P. The outer surface of the display panel 2.2-14P may be a developable surface (for example, the display panel 2.2-14P may be bent around axis 2.2-94). In active area AA, where polymer layer 2.2-130 overlaps a pixel of panel 2.2-14P, polymer layer 2.2-130 can also be bent about axis 2.2-94 (for example, the inner and outer surfaces of polymer layer 2.2-130 in active area AA may be developable). In inactive area IA, the inner and outer surfaces of polymer layer 2.2-130 may have composite curvature. The void can separate panel 2.2-14P from the inner surface of layer 2.2-130 and separate the outer surface of layer 2.2-130 from the inner surface of layer 2.2-92.

[0896] Other configurations of layer 2.2-130 may be used as needed. For example, the side of layer 2.2-130 facing the display panel 2.2-14P may have a developable surface in the active area AA, while the side of layer 2.2-130 facing layer 2.2-92 may have a composite curvature in the active area AA (for example, layer 2.2-130 may have a non-uniform thickness). Layer 2.2-92 may also have a different configuration. For example, the outer surface of layer 2.2-92 may have a composite curvature, while the inner surface of layer 2.2-92 in the active area AA and / or area IA may be a developable surface. Other configurations in which layer 2.2-92 and / or layer 2.2-130 have variable thickness may also be used. Multiple polymer structures may be joined in the inactive area IA. For example, in area IA, a ring-shaped polymer member, sometimes called a shroud trim, may be bonded to layer 2.2-130, which can form a shroud canopy member extending across the entire front surface of device 2.2-10. The shroud trim and shroud canopy may, if desired, be referred to individually or collectively as forming a shroud, shroud member(s), etc. Coloring (e.g., dyes, pigments, and / or other colorants) may be included in layer 2.2-130. For example, layer 2.2-130 may be colored to exhibit a visible light transmittance of 30-80% to help obscure internal structures of device 2.2-10, such as display panel 2.2-14P, from view when not in use.

[0897] Figure 2.2-6 is a front view of a portion of the display 2.2-14F and the display cover layer 2.2-92. The inner and outer surfaces of the display cover layer 2.2-92 that directly overlap the active area AA and the display panel 2.2-14P may be developable surfaces and / or may include areas of composite curvature. In an exemplary configuration, the inner surface of the cover layer 2.2-92 in area AA can bend about the bending axis 2.2-94 without exhibiting curvature about any axis perpendicular to axis 2.2-94, as described in relation to Figures 4 and 5A. The outer surface of the layer 2.2-92 in area AA may be a developable surface or a surface of composite curvature. Using a developable surface on the inward-facing side of the display cover layer 2.2-92 (and, if necessary, using a developable surface on the inward-facing side of the optional layer 2.2-130 in Figure 2.2-5B) can help ensure that the display panel 2.2-14P does not wrinkle or get damaged in any other way while bending the panel 2.2-14P to form a curved display shape that conforms to the shape of the user's head.

[0898] The display panel 2.2-14P may have an outward-facing, developable surface within the active area AA. This display panel surface may be bonded to the corresponding inner developable surface of layer 2.2-130 or the corresponding inner developable surface of layer 2.2-92, or (for example) separated from the inner surfaces of layer 2.2-130 and / or layer 2.2-92 by voids.

[0899] The inner and outer surfaces of part or all of the display cover layer 2.2-92 in the inactive area IA may be characterized by composite curvature, as needed. This allows for a smooth transition around the display 2.2-14F away from the active area, providing the device 2.2-10 with an attractive appearance and compact form factor. The composite curvature of the display cover layer 2.2-92 in the inactive area IA can also facilitate the placement of optical components below the inactive area IA in a desired orientation. If necessary, all areas of layer 2.2-92 may have composite curvature (for example, the inner and outer surfaces of layer 2.2-92 may have composite curvature in both area IA and area AA).

[0900] In the exemplary configuration of Figure 2.2-6, where the display cover layer 2.2-92 has a curved periphery and the inward and outward surfaces of the display cover layer 2.2-92 have composite curvature in the inactive area IA, the cross-sectional profile of the display cover layer 2.2-92 along each of the exemplary lines 2.2-100 in Figure 2.2-6 is curved (for example, the entire peripheral ring-shaped inactive area of ​​display 2.2-14F in the example of Figure 2.2-6 is covered by a portion of the display cover layer 2.2-92 having inner and outer surfaces with composite curvature). This type of shape of the display cover layer 2.2-92 can be produced by glass forming, polymer molding, machining, and / or other display cover layer fabrication techniques. Other configurations (e.g., configurations in which the display cover layer 2.2-92 has at least some developable surfaces (inner and / or outer surfaces) within the inactive area IA) may also be used. The configuration in Figure 2.2-6 is exemplary.

[0901] Figures 2.2-7, 2.2-8, and 2.2-9 are front views of an exemplary upper left portion of the display cover layer 2.2-92. Device 2.2-10 may have a symmetrical right-side cover layer portion. The example in Figure 2.2-7 shows how the periphery of the display cover layer 2.2-92 may have a straight edge (e.g., a roughly rectangular shape with a straight edge) and rounded corners. In the example in Figure 2.2-8, the display cover layer 2.2-92 has a teardrop shape on the upper left and right sides. Figure 2.2-9 shows how the upper corner of the display cover layer 2.2-92 may have a sweeping curve (e.g., to help soften the appearance of device 2.2-10 when viewed from the front).

[0902] Figures 10, 11, and 12 are front views of an exemplary lower left portion of the display cover layer 2.2-92. As shown in Figure 2.2-10, the lower half of the cover layer 2.2-92 may be characterized by a rectangular shape with rounded corners. The cover layer 2.2-92 in Figure 2.2-10 may have an upper portion having the type of shape shown in Figure 2.2-7 (as an example). In the nose bridge portion of the device 2.2-10, the cover layer 2.2-92 may have a recessed and curved nose bridge edge shape (see, for example, curved edge surface 2.2-90). In the exemplary configuration of Figure 2.2-11, the display cover layer 2.2-92 has a lower left and lower right side having a teardrop shape (for example, a shape that can be used with a display cover layer having the upper left and upper right teardrop shapes of the type shown in Figure 2.2-8). Figure 2.2-12 shows how the lower portion of the display cover layer 2.2-92 may have a more gently curved contour.

[0903] Generally, the upper and lower portions of the cover layer 2.2-92 may have any suitable contour when viewed from the front of the device 2.2-10. The shape used for the cover layer 2.2-92 may be determined by factors such as aesthetics, size, ability to facilitate the proper placement of optical components within the inactive area IA, and ability to provide the desired active area coverage (overlap on the active area AA). Any of the exemplary shapes of the upper portion of the device 2.2-10 shown in Figures 7, 8, and / or 9 may be used in combination with any of the exemplary shapes of the lower portion of the device 2.2-10 shown in Figures 10, 11, and 12. The overall shape of the cover layer 2.2-92 may be symmetrical with respect to the nose bridge (for example, the left and right halves of layer 2.2-92 may exhibit mirror symmetry). The shapes in Figures 7, 8, 9, 10, 11, and 12 are illustrative. Other shapes may be used as needed.

[0904] Figure 2.2-13 is an exploded top cross view of a portion of device 2.2-10, showing how the display cover layer 2.2-92 may have portions that overlap with the display panel 2.2-14P and portions that overlap with decorative cover structures such as the shroud 2.2-130 (for example, a ring-shaped shroud portion sometimes called a shroud trim or shroud trim member, which may optionally be attached in area IA to a shroud canopy covering the display 2.2-14F, such as an optional polymer layer 2.2-130). The decorative cover structures in the inactive area IA may be formed from separate structures made of metal, polymer, glass, or other materials, and / or other structures that can help conceal the overlapping components 2.2-104 from opaque masking layers (e.g., black ink layers) and / or other coatings on the inner surface of the display cover layer 2.2-92 and / or the shroud. Component 2.2-104 may include the sensor 16 and other input / output devices 2.2-22 shown in Figure 2.2-2. For example, component 2.2-104 may be optical components such as components 2.2-60, 2.2-62, 2.2-64, 2.2-84, 2.2-66, 2.2-68, 2.2-70, 2.2-72, 2.2-74, 2.2-76, 2.2-78, 2.2-82, and 2.2-80 shown in Figure 2.2-3. In the inactive area IA, the cover layer 2.2-92 may have curved inner and outer surfaces (e.g., surfaces with composite curvature). The shroud 2.2-102 (and, optionally, layer 2.2-130 in area IA) may optionally have corresponding inner and outer surfaces (e.g., surfaces with composite curvature). Component 2.2-104 can operate through the optical component windows of the corresponding areas within the shroud 2.2-102 (and optionally within layer 2.2-130 in area IA) and layer 2.2-92.These windows may be formed by recesses and / or through-hole openings in shroud 2.2-102 (and optionally layer 2.2-130) and / or layer 2.2-92, by window members installed within openings in shroud 2.2-102 (and optionally layer 2.2-130) and / or layer 2.2-92, by portions of shroud 2.2-102 (and optionally layer 2.2-130) and / or layer 2.2-92 that provide sufficient light transmission for satisfactory operation of the overlapping components, and / or by other structures within shroud 2.2-102 (and optionally layer 2.2-130) and / or window 2.2-92.

[0905] If necessary, component 2.2-104 may include components such as a camera (e.g., a visible and / or infrared image sensor, a time-of-flight sensor, a structured optical three-dimensional sensor, etc.) that senses the optical distortion caused by the curved shape of the curved inner and / or outer surfaces of the cover layer 2.2-92. For example, the camera or other optical component 104 may operate through a portion of the cover layer 2.2-92 in an inactive area IA characterized by an outer surface with composite curvature and an inner surface with composite curvature or a deployable inner surface. In this type of scenario, the control circuit of device 2.2-10 may be configured to digitally compensate for the optical distortion introduced as light (e.g., light from a real-world image) passes through layer 2.2-92 to the camera or other optical sensor. As an example, the amount of image distortion (e.g., stretching, shift, keystone toning, barrel distortion, pincushion distortion, and / or other optical distortions) introduced by layer 2.2-92 can be measured and characterized for each optical component operating through layer 2.2-92 (e.g., through a portion of layer 2.2-92 in an inactive area IA having an inner and / or outer surface of composite curvature). During the operation of device 2.2-10, image data captured by the camera and / or other sensor data collected by the optical component over which layer 2.2-92 is superimposed can be compensated accordingly (e.g., digital image warping of an equal and opposite amount can be applied to the captured image data to eliminate the known distortion effect of layer 2.2-92). In this way, high-quality (distortion-free) images and / or other sensor data can be collected by the camera and / or other optical components operating through the curved portion of layer 2.2-92. This allows layer 2.2-92 to have an attractive shape (e.g., a shape having one or more surfaces characterized by composite curvature).

[0906] When assembled into device 2.2-10, the display cover layer 2.2-92 and the shroud 2.2-102 (and optionally layer 2.2-130) can be attached to the polymer housing structure within the main housing portion 2.2-26M, the metal housing wall, or the exposed edge portion of another housing structure. As an example, the main housing portion 2.2-26M may have polymer sidewall members that extend around the periphery of the display cover layer 2.2-92 and support the peripheral edge of the display cover layer 2.2-92. The shroud 2.2-102 may have a ring shape that extends along the edge of the display cover layer 2.2-92 within the inactive area IA. In an exemplary configuration, adhesive is used to attach the display cover layer 2.2-92 to the shroud 2.2-102 (and / or layer 2.2-130), and adhesive is used to attach the shroud 2.2-102 (and / or layer 2.2-130) to the exposed leading edge of the side wall of the main housing portion 2.2-26M. Component 2.2-104 may be attached to the shroud 2.2-102 (and / or layer 2.2-130) and / or supported on an internal housing structure (e.g., a bracket, frame member, etc.) aligned with the optical window and the corresponding portion of layer 2.2-92 in the shroud 2.2-102 (and / or layer 2.2-130).

[0907] Figure 2.2-14 is a side cross-sectional view of a portion of display 2.2-14F. In the example of Figure 2.2-14, display panel 2.2-14P is a three-dimensional display panel having an array of pixels P on which a lenticular lens 2.2-106 is superimposed (for example, display panel 2.2-14P is an automated stereoscopic display that generates a naked-eye three-dimensional image for an observer such as observer 2.2-50 in Figure 2.2-1). The lens 2.2-106 may, as an example, be formed from a semi-cylindrical lens element stretched along a row of pixels (for example, a lens element extending parallel to the Z dimension in the example of Figure 2.2-14). If necessary, the lens 2.2-106 may be omitted (for example, display panel 2.2-14P may have an array of pixels P on which the lens 2.2-106 is not superimposed to form a two-dimensional display).

[0908] A gap such as 2.2-114 can separate the display panel 2.2-14P of the display 2.2-14F from the display cover layer 2.2-92. An optional layer 2.2-130 can be formed within the gap 2.2-114 in Figure 2.2-14, resulting in layer 2.2-130 having an outer surface separated from layer 2.2-92 by a first gap and an opposing inner surface separated from lens 2.2-106 and the pixels P of the display panel 2.2-14P by a second gap. In configurations where lens 2.2-106 is present, the gap 2.2-114 (and the resulting absence of direct contact between the inner surface of layer 2.2-130 and lens 2.2-106) may allow lens 2.2-106 to operate satisfactorily. The display cover layer 2.2-92 and the optional layer 2.2-130 may be formed from transparent materials such as glass, polymer, transparent ceramic, crystalline materials such as sapphire, one or more sublayers of these materials, and / or other materials laminated together (e.g., using an adhesive). A configuration in which layer 2.2-92 is a glass layer and layer 2.2-130 is a polymer layer may be described herein as an example.

[0909] The coating may be provided on one or more layers within the display cover layer 2.2-92. As shown in the exemplary configuration of Figure 2.2-14, the display cover layer 2.2-92 may include, for example, layers such as layer 2.2-108 formed from one or more sublayers (e.g., one or more layers of glass and / or polymer), a polymer layer that helps provide safety glass functionality to layer 2.2-92 (see, for example, an exemplary polymer film 112 attached to the inner surface of glass layer 2.2-108 to form a laminated glass layer), and a coating 2.2-110 on the front (outward) surface of layer 2.2-92 (e.g., the outer surface of glass layer 2.2-108). The coating 2.2-110 may be an anti-reflective coating formed from one or more inorganic dielectric layers and / or other layers having thicknesses and refractive index values ​​selected to help minimize visible light reflection from the outermost surface of layer 2.2-92 and maintain a desired appearance (e.g., achromatic hues) of layer 2.2-92. If necessary, the display panel 2.2-14P may be a touch-sensitive display (e.g., a display with a capacitive touch sensor circuit superimposed on it or incorporating a capacitive touch sensor circuit). In a configuration where the display 2.2-14F is touch-sensitive, the outermost surface of layer 2.2-92 may be coated with an oleophobic coating layer (e.g., a fluoropolymer layer).

[0910] To help strengthen layer 2.2-92, layer 2.2-108 may be formed from chemically strengthened glass (e.g., a glass layer treated in an ion exchange bath to place the outer surface of the glass layer under compression relative to the interior of the glass layer). This may help layer 2.2-108 withstand scratches and cracks. Layer 2.2-108 may be formed from a single glass layer, a single polymer layer, a stack of two laminated glass layers (e.g., a first glass layer and a second glass layer laminated with a polymer layer), a stack of two polymer layers, three or more polymer and / or glass layers, etc. If necessary, layer 2.2-108 may be formed from a hybrid stack of layers including one or more glass layers attached to one or more polymer layers. As an example, layer 2.2-92 may include a rigid structural polymer layer covered with a thin glass layer (e.g., a glass layer attached to a structural polymer layer using heat and / or pressure, or a glass layer attached to a structural polymer layer using a polymer adhesive layer). In this type of configuration, a thin glass layer can help protect the structural polymer layer from scratches.

[0911] One or more structures of layer 2.2-92 (e.g., coating 2.2-110, or layers(s) forming layer 2.2-108, layer 2.2-112, or any optional layer 2.2-130) may optionally comprise dyes, pigments, or other colorants to produce a desired achromatic (e.g., gray or black) or non-achromatic (e.g., red) color. Thin metal coatings, polarizers, and / or other structures can also be incorporated into layer 2.2-92 to help impart desired optical properties to layer 2.2-92 and / or to provide a desired appearance to layer 2.2-92.

[0912] If necessary, the portion of layer 2.2-92 overlapping the optical component 2.2-104 and / or other portions of layer 2.2-92 may be provided with a coating to help prevent scratches that could adversely affect the optical quality of component 2.2-104. As shown in Figure 2.2-15, for example, the display cover layer 2.2-92 may have a transparent layer (e.g., one or more layers of polymer, glass, and / or other transparent layers such as layer 2.2-108 in Figure 2.2-14), such as transparent layer 2.2-116. Transparent layer 2.2-116 may be covered with one or more coating layers, such as coating layer 2.2-118. Layer 2.2-118 may be a thin film layer formed from an inorganic material (e.g., oxide, nitride, diamond-like carbon, etc.) that helps to resist scratches. This type of approach can be used, for example, to ensure that the portion of the display cover layer 2.2-92 overlapping the optical component 2.2-104 does not become cloudy even if scratched, when layer 2.2-116 is formed from a material such as a polymer that may be prone to scratching when exposed to excessive friction from sharp external objects. Layer 2.2-118 may also be called a hard coat and may have a higher hardness (e.g., a higher Mohs hardness) than layer 2.2-116. Layer 2.2-118 may be a thin film coating with a thickness of less than 3 microns, less than 2 microns, less than 1 micron, less than 0.5 microns, or other suitable thickness.

[0913] Another method to help prevent undesirable scratches on the surface of the display cover layer 2.2-92 where layer 2.2-92 overlaps the optical component 2.2-104 is shown in the side section view of the display cover layer 2.2-92 in Figure 2.2-16. As this example shows, the outer surface of the display cover layer 2.2-92 may be provided with a recess, such as recess 2.2-120 (e.g., a shallow circular indentation, or an indentation with a rectangular or other footprint). This places the recessed display cover layer surface 2.2-124 of recess 2.2-120 below the peripheral outer surface 2.2-122 of layer 2.2-92. When the device 2.2-10 is placed on a tabletop or other surface, the non-recessed portion of the surface of layer 2.2-92 (outer surface 122) comes into contact with the tabletop surface, thereby helping to prevent the tabletop surface from coming into contact with the recess of the surface of layer 2.2-92 (surface 2.2-124). As a result, the concave surfaces 2.2-124 that overlap with component 104 remain scratch-free. Therefore, even if layer 2.2-92 is subjected to excessive wear, clouding generally does not occur in the area of ​​layer 2.2-92 that overlaps with component 104.

[0914] Layer 2.2-92 may be formed from a material having optical properties that match those of the superimposed optical component 2.2-104. For example, if a portion of layer 2.2-92 in an inactive area IA is configured to operate at visible and infrared wavelengths, then that portion of layer 2.2-92 may have sufficient visible and infrared light transmittance to allow the superimposed component to operate satisfactorily at visible and infrared wavelengths. In configurations where the bulk material of layer 2.2-92 does not have the desired optical properties for the optical component, an optical component window member (e.g., a disk of window material such as infrared-transmitting glass and, optionally, a disk of visible-light-transmitting glass, or other inserted window member) can be fitted into the opening in layer 2.2-92 that overlaps the optical component.

[0915] As an example, consider a configuration in which layer 2.2-92 is transparent to visible light but has low transmittance at infrared wavelengths. Optical components in this type of configuration can operate at infrared wavelengths. To ensure that the optical components can transmit and / or receive infrared light through layer 2.2-92, through-hole openings and infrared-transparent optical component window members, such as infrared-transparent discs, can be provided in layer 2.2-92. The infrared-transparent window members can be made from a different material than the material forming layer 2.2-92 and can be installed within the through-hole openings of layer 2.2-92. This type of configuration is shown in the side cross-sectional view of Figure 2.2-17, in which the display cover layer 2.2-92 is provided with an optical component window member 2.2-92W within the through-hole openings in layer 2.2-92. Component 2.2-92W may be a glass optical component window component that is transparent to infrared light (and optionally transparent to visible light), but the surrounding portion of layer 2.2-92 may be formed from a different material (e.g., polymer, different glass material, etc.). By providing an infrared-transmitting window in layer 2.2-92, an infrared optical component (e.g., optical component 2.2-102 in Figure 2.2-17) can transmit and / or receive infrared light through the display cover layer 2.2-92 (e.g., through the window in the display cover layer), even if layer 2.2-92 is formed from a material that is not infrared-transmitting. Using this approach, it is possible to provide an optical component window having any preferred optical properties (e.g., a desired amount of opacity, light transmittance, reflectance, absorptiveness, and / or haze level, desired polarization properties, etc.) that differ from the rest of layer 2.2-92. 2.3: Systems with auxiliary lighting

[0916] Figure 2.3-1 is a side cross-sectional view of a head-mounted device in an exemplary configuration, including a lighting system for providing ambient illumination. The head-mounted device 2.3-10 in Figure 2.3-1 may have optical sensors. These sensors may include a camera. The camera of device 2.3-10 may have a lens and an image sensor configured to capture images at ultraviolet, visible, and / or infrared wavelengths.

[0917] Several cameras (for example, a type of camera sometimes called a scene camera) may be used to capture images of the user's environment displayed in real time on display 2.3-14 (e.g., real-time passthrough video). Cameras within device 2.3-10 may also be used to track the position and movement of external objects. As an example, a tracking camera may track the user's hand (see, e.g., hand 2.3-30H) or the user's torso or other body part (see, e.g., user body part 2.3-30B). Hand gesture input may be used, as an example, to control the operation of device 2.3-10. Body part monitoring may be used to allow the user's body movements to be replicated by content displayed in the virtual environment. If necessary, cameras may be used to track the position of external accessories (e.g., the position and movement of controllers moved by the user to control device 2.3-10). In some scenarios, a visual inertial odometry (VIO) system or other system that determines the position, movement, and / or orientation of device 2.3-10 relative to the environment surrounding device 2.3-10 may be formed by combining data from one or more cameras within device 2.3-10 with additional sensor data (e.g., data from an inertial measurement unit). The cameras may perform dedicated functions (such as tracking, visual inertial odometry, scene capture, distance measurement, face recognition, and 3D image capture for environment mapping), or two or more of these operations may be performed by a shared camera.

[0918] It may be desirable to enable users of device 2.3-10 to operate device 2.3-10 in low-light conditions. For example, a user may be viewing content on display 14 while in a dark room or inside a dark vehicle. To ensure that camera tracking functions such as hand tracking, body tracking, accessory tracking, and optionally other camera-based functions (e.g., visual inertial odometry) can be performed satisfactorily, device 2.3-10 may provide auxiliary illumination. The auxiliary illumination may be provided by a light source that enhances any available ambient light by generating auxiliary ultraviolet light, auxiliary visible light, and / or auxiliary infrared light. In an exemplary configuration, the auxiliary illumination is provided at infrared wavelengths because this light is detectable by the tracking camera or other camera with infrared sensing capability and is invisible to the human eye. Because the auxiliary infrared illumination is invisible, people near the user of device 2.3-10 (e.g., people in the same room or vehicle as the user) are not disturbed by the presence of the auxiliary illumination.

[0919] Any suitable light source may be used to form the auxiliary illumination system for device 2.3-10 (e.g., light-emitting die, laser, etc.). In an exemplary configuration, these light-emitting devices are laser diodes or light-emitting diodes that emit infrared light at a wavelength of 940 nm or other infrared wavelengths (e.g., one or more wavelengths such as 740-1500 nm, at least 800 nm, 940 nm, at least 900 nm, 800-1200 nm, 900-1000 nm, 750-1100 nm, 800-1100 nm, less than 1500 nm). Device 2.3-10 may have N cameras and M auxiliary light sources that use auxiliary illumination. The values ​​of N and M may be 1-10, at least 2, at least 3, at least 4, at least 6, at least 8, 2-10, 4-6, 2-4, less than 10, less than 5, less than 4, or other suitable numbers. The value of N may be greater than the value of M, equal to the value of M, or less than the value of M. For example, there may be four cameras using auxiliary infrared illumination, and two light sources emitting the auxiliary illumination.

[0920] A camera using auxiliary infrared illumination may be configured to be sensitive to the wavelengths illuminated by the auxiliary illumination system (e.g., the infrared wavelengths associated with M auxiliary light sources). The camera may also be sensitive to visible wavelengths so that it can operate without any auxiliary illumination when sufficient visible ambient illumination is present. To help avoid infrared interference during normal ambient illumination conditions, the auxiliary illumination system may, for example, be configured to emit light in a narrow infrared band (e.g., 940 nm), and the camera may have a filter that allows visible light to pass through but blocks all infrared light except for that in the narrow infrared band. In another exemplary configuration, the camera is highly sensitive across the visible spectrum (e.g., 380–740 nm) and the infrared spectrum (e.g., 740–1000 nm, or another suitable broader infrared wavelength band where infrared auxiliary illumination is generated). If necessary, a switchable filter can be provided to block infrared light from the camera when auxiliary infrared illumination is not used and to allow infrared light to pass through when auxiliary infrared illumination is used.

[0921] As shown in Figure 2.3-1, the right side of device 2.3-10 may include a first camera, such as camera 2.3-50, oriented in a direction such as direction 2.3-54 (e.g., the -Z direction and slightly the +Y direction), and a second camera, such as camera 2.3-52 (sometimes called a forward-facing camera), oriented in a forward direction such as direction 2.3-56 (e.g., the +Y direction and slightly the -Z direction). The left side of device 2.3-10 may have a corresponding pair of similarly oriented cameras. The fields of view of the left and right cameras may be configured to overlap in front of device 2.3-10, resulting in seamless coverage in front of the user. If desired, cameras 2.3-50 and 2.3-52 may be replaced by a single camera (e.g., a camera in the position of camera 2.3-52, a camera in the position of camera 2.3-50, or another suitable forward-facing and / or downward-facing camera capturing images while looking outward from a location on the front side F of device 2.3-10). For example, there may be a single tracking camera (e.g., camera 2.3-52) on the right side of device 2.3-10 and a corresponding single tracking camera on the left side of device 2.3-10.

[0922] Regardless of the number of tracking cameras provided on each side of device 2.3-10, there may be a right-side infrared light source, such as light source 2.3-58, that provides auxiliary illumination (infrared light) in direction 2.3-60 to illuminate objects such as the hand 2.3-30H, the body 2.3-30B, and other external objects for the right-side tracking camera(s) of device 2.3-10, and there may be a corresponding left-side infrared light source that provides auxiliary infrared light for the left-side tracking camera(s) of device 2.3-10. Providing auxiliary illumination to the tracking camera(s) on that side of device 2.3-10 using a single auxiliary infrared light source on each side of device 2.3-10 may help save space within the narrow range of housing 2.3-26.

[0923] The auxiliary lighting system of device 2.3-10 can provide infrared illumination to an area (angle range) larger than the area (angle range) covered by the tracking camera(s)

[0924] As an example, consider the coverage of the auxiliary lighting system of device 2.3-10 in Figure 2.3-1 in the YZ plane. As shown in the side view of Figure 2.3-1, the downward-facing camera 2.3-50 may be characterized by a field of view A1 in the YZ plane, and the forward-facing camera 2.3-52 may be characterized by a field of view A3 in the YZ plane. These fields of view may overlap to provide continuous tracking coverage in the YZ plane. If necessary, a single tracking camera can be used to provide the same amount of coverage or another suitable amount of coverage in the YZ plane. The example in Figure 2.3-1 is illustrative.

[0925] Auxiliary illumination from light source 2.3-58 can be characterized by the illumination angle A2 in the YZ plane. The value of A2 may be greater than, equal to, or less than the combined field of view of cameras 2.3-50 and 2.3-52, or greater than, equal to, or less than the field of view of a single tracking camera used in place of cameras 2.3-50 and 2.3-52. In an exemplary configuration, A2 is smaller than the overall field of view of the tracking camera(s) and directed outward forward and downward in front of device 2.3-10 (where hand and body tracking is most likely to occur). The use of a somewhat reduced illumination area for the auxiliary illumination system (e.g., an illumination area smaller than the area covered by the tracking camera system) may help conserve power when operating for extended periods in dark operating environments while maintaining the ability to track objects in all areas except the periphery.

[0926] Figure 2.3-2 is a top view of device 2.3-10, showing how the device 2.3-10 may include cameras on both the left and right sides of the support structure 2.3-26. The center of housing portion 2.3-26M may include nose bridge portion 2.3-26NB. Nose bridge portion 2.3-26NM may have a lower edge with a curved shape configured to rest on the user's nose while device 2.3-10 is fitted to the user's face. Nose bridge portion 2.3-26NB can connect the right housing portion 2.3-26R to the left housing portion 2.3-26L. Optical components 2.3-62 may include a lateral visible light camera, a forward-facing visible light camera, a time-of-flight camera (e.g., a time-of-flight sensor in the forward-facing nose bridge section 2.3-26NM), a three-dimensional structured light camera (e.g., left and right structured light cameras adjacent to the nose bridge section 2.3-26NB), a flicker sensor for detecting ambient light fluctuations (e.g., 60Hz fluctuations associated with indoor artificial lighting), an ambient light sensor, and the like.

[0927] The right camera 2.3-52 may be supported within the right housing portion 2.3-26R, and the corresponding left camera 2.3-52' may be supported within the left housing portion 2.3-26L. Similarly, an optional additional right camera, such as camera 2.3-50 in Figure 2.3-1, can be supported within the right housing portion 2.3-26R, and a corresponding optional additional left camera can be supported within the left housing portion 2.3-26L. In this type of configuration, auxiliary illumination for a single right-side tracking camera or a pair of right-side tracking cameras may be provided by a right-side auxiliary light source 2.3-58, and auxiliary illumination for a left-side camera(s) may be provided by a left-side auxiliary light source 2.3-58'.

[0928] During auxiliary lighting operation, light sources 2.3-58 and 2.3-58' generate auxiliary lighting in directions 2.3-60 and 2.3-60', respectively. As described in relation to the relative coverage areas of the camera and light sources in Figure 2.3-1, the illumination coverage area of ​​the auxiliary lighting system does not need to exactly match the coverage area of ​​the camera. For example, the tracking cameras on each side of device 2.3-10 may be characterized by a field of view in the XY plane that is larger than the coverage angle of the associated light source. Configurations can also be used in which illumination from the auxiliary light sources on each side of device 2.3-10 is provided over the same angular range as the camera's field of view, or configurations in which illumination is provided over a wider angular range than the camera's field of view.

[0929] Auxiliary lighting may be provided globally across a relatively large fixed area, or a desired area may be covered by activating or moving a narrower beam of illumination toward or across the desired area. If necessary, a dynamic lighting system with directional or addressable beams of auxiliary lighting may be directional or activated so that the beam follows the user's hand or other object of interest. In this way, power is not unnecessarily consumed to illuminate areas that do not contain the object to be tracked.

[0930] Figures 2.3-5 and 2.3-6 are side views of exemplary fixed-area auxiliary illumination sources. The exemplary light source 2.3-58 in Figure 2.3-3 has a semiconductor light-emitting device 2.3-70. Device 2.3-70 may be a solid-state light-emitting device such as a light-emitting diode, superluminescent light-emitting diode, resonant cavity light-emitting diode, end-face light-emitting diode, or vertical cavity surface light-emitting diode, and may be a diode-pumped laser such as a diode-pumped fiber laser or other diode-pumped laser. As shown in Figure 2.3-3, device 2.3-70 may be mounted on an arbitrary interposer 2.3-72 (e.g., using solder). The interposer 2.3-72 may be mounted on a package substrate 2.3-74 (e.g., a printed circuit board). During operation, device 2.3-70 may emit infrared light that is diffused over a desired illumination area by one or more optical structures overlapping device 2.3-70. In the example of Figure 2.3-3, these optical structures include an optional overmolded polymer lens 3.3-76 and an optional secondary optical structure such as a peanut lens 3.3-78. It is also possible to form a curved reflective optical structure on the interposer 2.3-76 or substrate 2.3-74 to enhance the focusing of light from the sides and / or rear. Optical structures overlapping device 2.3-70 can be used to shape the light intensity to produce a desired far-field distribution different from the native light source intensity distribution (e.g., a light-emitting diode with a Lambertian intensity distribution). Optionally, safety reinforcement structures such as resistive safety traces or capacitive traces may be embedded in or overlapped with the optical system, or a photodetector may be used to form a closed loop with a safety interlock on the light source driver (e.g., in relation to the type of modular architecture shown in relation to Figures 2.3-5 to 2.3-8).

[0931] In the exemplary configuration shown in Figure 2.3-4, the light-emitting device 2.3-70 (e.g., a laser) is mounted beneath a light-diffusing structure such as a beam-shaping layer 2.3-82. The layer 2.3-82 may be supported within the light source package 2.3-80. The device 2.3-70 may be mounted within the package 2.3-80 on any interposer 2.3-72 on a printed circuit board or other substrate. During operation, the device 2.3-70 in Figure 2.3-4 can radiate infrared light, which has been laterally diffused by the beam-shaping layer 2.3-82, upward to cover a desired illumination area (e.g., + / - 60° or other suitable angular range).

[0932] In general, any suitable optical component that functions as a light-diffusing structure may overlap with device 2.3-70 in Figures 2.3-5 and 2.3-6. These optical components may include optical components such as refractive beam shaping optical components, diffractive optical systems, diffuse optical systems, optical nanostructures (e.g., thin two-dimensional metamaterial layers such as patterned structures of transparent dielectrics with subwavelength dimensions that form metasurfaces configured to spread the emitted beam), and curved reflectors. Multiple devices 2.3-70 may be mounted in a common package, and / or multiple packaged devices 2.3-70 may be mounted in adjacent printed circuits when forming a light source 2.3-58. The use of a single light-emitting device 2.3-70 when forming a light source 58 in the examples in Figures 2.3-5 and 2.3-6 is illustrative.

[0933] Figures 2.3-7 and 2.3-8 are side views of exemplary dynamic pattern illuminators that may be used in a lighting system for device 2.3-10. Using the type of light source shown in Figures 2.3-7 and 2.3-8, the control circuit 2.3-12 can selectively activate or steer the emitted beam of infrared light so that it can provide targeted auxiliary illumination to one or more target objects.

[0934] In the example of Figure 2.3-5, the light source 2.3-58 has an array of light-emitting devices 2.3-70. Device 2.3-70 may include multiple semiconductor dies mounted on a substrate such as a printed circuit board 2.3-84 in package 2.3-86, may include multiple individually addressable emitters, or may include multiple individually addressable segments of emitters mounted on a substrate such as silicon, ceramic, printed circuit board 2.3-84, or other substrate in package 2.3-86. Other optical components, such as a zoned beam shaping layer or layer 2.3-88, may overlap with device 2.3-70. Layer 2.3-88 may have multiple zones, each having a separate beam steering and beam shaping optical structure. These structures may be refractive structures, diffracting structures, nanostructures, etc. Structures on the surfaces of both layer 2.3-88 and / or multiple layers of layer 2.3-88 may be used, having vertically aligned or unaligned zones. Each zone can be used to steer and shape the beam of light emitted from individual light-emitting devices in different, distinct directions. For example, a first zone can direct a beam of light emitted perpendicularly from a first device 2.3-70 to the left, and a second zone can direct a beam of light emitted perpendicularly from a second device 2.3-70 to the right. By superimposing an array of individually controlled devices 70 with a corresponding array of individualized beam steering structures, each device 2.3-70 can be configured to emit a beam of light in different, distinct directions (see, for example, the exemplary beam 2.3-90), providing the light source 2.3-58 in Figure 2.3-5 with the ability to emit a steered beam of light. The emission area of ​​each beam may overlap with adjacent beams to avoid potential gaps in coverage. All beams 2.3-90 may be emitted simultaneously, or one or more selected beams 2.3-90 may be emitted at a time. If desired, beams 2.3-90 may be emitted sequentially (for example, to scan the beam emitted from light source 58 across the target area).

[0935] Another exemplary light source that may be used in forming a dynamic pattern illuminator for the auxiliary lighting system of device 2.3-10 is shown in Figure 2.3-6. The light source 2.3-58 in Figure 2.3-6 may have one or more light-emitting devices, such as device 2.3-70, which emits one or more light beams, such as light beam 2.3-92 (e.g., an infrared light beam). Device 2.3-70 may be mounted on a printed circuit in package 2.3-96 or on other substrate 2.3-94. The electrically controlled beam steering 2.3-98 may have one or more beam steerings, such as a steerable micro-electromechanical system mirror 2.3-100 or other electrically adjustable beam steering elements, controlled by a control signal from control circuit 2.3-12. If it is desirable to radiate light in a first direction, the mirror 2.3-100 may be positioned in a first orientation that reflects beam 2.3-92 to produce a first radiated beam 2.3-102. If it is desirable to radiate light in a second direction, mirror 2.3-100 may be positioned in a second orientation different from the first orientation, thereby reflecting beam 2.3-92 to produce a second radiated beam 2.3-104. Mirror 2.3-100 may be positioned in any suitable number of different orientations (e.g., at least 2, at least 10, at least 25, at least 100, less than 5000, less than 1000, less than 500, or any other suitable number). Mirror 2.3-100 may be rotated around a single axis (to change the angle of the radiated light beam along a single dimension) or around two axes (e.g., to arbitrarily change the angle of the emitted light beam in two dimensions). If desired, beam shaping optics (e.g., beam parallelizing lenses) can be incorporated into the beam steering 2.3-98 to help ensure that the steered beam has a desired intensity profile.

[0936] If desired, a hybrid illuminator architecture can be used to selectively activate multiple channels of device 2.3-70, as described in relation to Figure 2.3-5, or multiple devices 2.3-70, to provide one or more additional dimensions of dynamic illumination to beam steering optical systems such as mirror 2.3-100 in Figure 2.3-6.

[0937] A light source emitting a static wide-area beam (see, for example, the exemplary light source 2.3-58 in Figures 2.3-5 and 2.3-6) can be configured to emit a light beam of any suitable shape to help provide auxiliary illumination for the tracking camera of device 2.3-10. Figure 2.3-7 is a graph showing how light source 2.3-58 can be configured to emit a circular beam field of regard (FoG), such as a circular beam 2.3-110 (e.g., a beam of infrared light with a full width at half maximum (FWHM) intensity characterized by an angular spread of + / -60° or other suitable coverage area), or how it can be configured to emit a rectangular beam FoG, such as a rectangular beam 2.3-112 with a similar vertical angular spread and a smaller horizontal angular spread. Two rectangular beams, such as beam 2.3-112, can be generated side by side (as an example) to provide sufficient horizontal illumination range for both the left and right cameras in device 2.3-10.

[0938] In the most common use cases, the goal of an illumination system is to provide a uniform signal-to-noise ratio for an illuminated scene captured by one or more cameras. Within a desired FWHM 2-D FoG, a uniform far-field intensity can be achieved in each instantaneous FoG (iFoG) to provide the camera with uniform illumination and operating range. However, there are cases where a non-uniform far-field intensity distribution is desired. For example, when the illumination target is flat or when camera aperture vignetting is significant, a symmetric "batwing" intensity distribution can be used to compensate for the relative intensity drop of the camera image sensor. Further examples include asymmetric intensity distributions such as cameras aligned in a non-coaxial orientation to the illumination system, targets such as hands with asymmetric generation / stagnation across the FoG, multiple illuminators with overlapping FoGs, multiple non-coaxial cameras, and irregular occlusion in specific FoG regions.

[0939] The graphs in Figures 2.3-10 and 2.3-11 show exemplary beam outputs (angle beam distributions) associated with a dynamically adjustable lighting system. In the example in Figure 2.3-8, a light source such as light source 58 in Figure 2.3-5 or light source 58 in Figure 2.3-6 is configured to produce a beam having an elongated rectangular shape (e.g., a rectangle with a horizontal spread greater than its vertical spread). Using beam steering, light source 2.3-58 can radiate this elongated rectangular beam to one or more vertical locations, such as exemplary location 2.3-114 in Figure 2.3-8. In the type of configuration shown in Figure 2.3-5, each light-emitting device 2.3-70 may produce different individual elongated rectangular beams, each associated with different individual vertical positions at the output of light source 2.3-58. One or more of these beams may be emitted simultaneously by turning on one or more of the respective light-emitting devices 2.3-70. In the configuration of the type shown in Figure 2.3-6, the light-emitting device 2.3-70 can generate beams such as beam 2.3-92 in Figure 2.3-6, which are steered by beam steering 2.3-98 to a desired location (e.g., exemplary location 2.3-114 in Figure 2.3-8) and / or other locations, thereby providing the light source 2.3-58 with the desired coverage.

[0940] In the exemplary example shown in Figure 2.3-8, light is output over a vertical angular range that is larger than the horizontal range. Additional horizontal coverage can be supplied using an additional light source (e.g., a light source on the opposite side of device 2.3-10). In this way, a desired angular output range (e.g., ±60° in both the horizontal and vertical dimensions, or other suitable angular output range) can be covered.

[0941] In the exemplary configuration of Figure 2.3-9, light source 2.3-58 (a dynamically configured light source such as light source 58 in Figure 2.3-5 or Figure 2.3-6) is configured to supply a relatively small circular or square output beam that can be steered both horizontally and vertically to produce a desired overall coverage amount.

[0942] In both static light sources without a controllable beam and light sources with dynamically patterned output, beam power can be controlled in a binary (on / off) or analog manner (e.g., by continuously or stepwise adjusting the output power between two or more different output levels). As shown in Figure 2.3-9, for example, light may not be output in certain parts of a coverage area such as area 2.3-116 (e.g., the beam power may be 0 for these areas), full-power light may be output in areas such as area 2.3-118 (e.g., the beam power may be maximized for these areas), and intermediate power levels may be used when supplying output light to other areas such as area 2.3-120 directly adjacent to area 2.3-118.

[0943] A configuration in which full-power light is output only to a subset of the entire coverage area of ​​the light source 58 can help device 2.3-10 use power efficiently. As shown in the diagram of Figure 2.3-9, for example, one or more external objects of interest, such as object 2.3-122, may exist within the coverage area of ​​a given light source. Device 2.3-10 may, as an example, track the user's hand or other external objects. When these objects are relatively small compared to the overall field of view of the camera in device 2.3-10, power can be saved by limiting the output of the auxiliary lighting (or at least limiting the output of the full-power auxiliary lighting) to only the area that overlaps with the tracked external object.

[0944] In the example in Figure 2.3-9, object 2.3-122 (e.g., the user's hand or other body part or other object in the user's environment) is actively tracked by device 2.3-10. As a result, the auxiliary lighting system of device 2.3-10 is used to provide full-power illumination to area 2.3-118 overlapping object 2.3-122. Elsewhere within the coverage area of ​​light-emitting device 58, the beam power is reduced (see, for example, intermediate power area 2.3-120) or completely blocked (see, for example, unilluminated area 2.3-116). This type of approach may be used for either a scanning beam configuration (e.g., using a scanning mirror device or other beam steering as described in relation to Figure 2.3-6) or a light source with an addressable array of devices 70 (e.g., light source 58 in Figure 2.3-5) where each can provide output in a different direction.

[0945] In areas such as area 2.3-116 in Figure 2.3-9, there is no auxiliary lighting, and therefore items in these areas do not receive auxiliary lighting. Nevertheless, when an object such as object 2.3-122 is tracked, device 2.3-10 can monitor the position and direction of movement of object 2.3-122 in real time. This allows device 2.3-10 to provide full-power auxiliary lighting to the area overlapping object 2.3-122 and intermediate-power (or full-power as needed) auxiliary lighting to the portion of the output area of ​​light source 58 directly adjacent to object 2.3-122 (e.g., areas where object 2.3-122 may move and / or is expected to occupy in the near future based on tracked movement). If the position of object 2.3-122 moves to one of those adjacent areas, device 2.3-10 can increase the auxiliary lighting on those areas to full power and update the beam power so that the adjacent areas again have intermediate-power level coverage.

[0946] The multi-power-level beam scheme in Figure 2.3-9 is described in relation to the two-dimensional scanning beam from light source 2.3-58 in Figures 7 and 8, but such adjustable power output schemes may be used with light source 2.3-58 that provides a one-dimensional adjustable directional light source (e.g., a light source that generates a slice of auxiliary illumination of the type shown in Figure 2.3-8) and / or with a fixed-area light source. In a fixed-area light source scheme, for example, a right-side light source 58 of the type shown in Figure 2.3-3 or Figure 2.3-4 can be used to provide supplemental illumination for tracking object 2.3-122 in front of the right-side camera(s) of device 2.3-10, and a left-side light source 58 of the type shown in Figure 2.3-3 or Figure 2.3-4 can be used to provide supplemental illumination for tracking object 2.3-122 in front of the left-side camera(s) of device 2.3-10. Device 2.3-10 can activate either the right-side light source, the left-side light source, or both, depending on the current and expected locations of object 2.3-122.

[0947] Another way to help use power efficiently for an auxiliary lighting system involves using light source 2.3-58 to generate auxiliary lighting only when the camera receiving the auxiliary lighting would benefit from it. For example, in bright lighting conditions, the ambient visible light provides sufficient illumination, so the auxiliary infrared light beam can be turned off (or at least reduced to a lower level than it would otherwise be used) to help conserve power. The auxiliary lighting may be activated when dim ambient lighting conditions are detected, or when other suitable conditions that trigger the generation of auxiliary lighting are detected.

[0948] Figure 2.3-10 is a flowchart illustrating an exemplary operation of the electronic device 2.3-10. During the operation of block 2.3-150, device 2.3-10 may be used to provide content to the user, such as visual content, audio content, and other outputs. Device 2.3-10 may, for example, be worn on the user's head while an image is presented for viewing. The operation of block 2.3-150 may be performed while device 2.3-10 is in a normal operating environment with a sufficient visible ambient light level.

[0949] Visual content may be presented to the user on display 2.3-14. This visual content may include camera images from a camera in device 2.3-10 (e.g., passthrough video) and / or other content. In some scenarios, computer-generated content (sometimes referred to as virtual content) may be overlaid on real-world content from a camera in device 2.3-10. In this type of mixed reality environment, camera data may be used to help track the location of the user's hands and other real-world objects, thereby helping to register the overlay of virtual content onto real-world images. For example, by tracking the location of the user's hands, a computer-generated image of gloves can be precisely overlaid on a real-world image of the user's hands. By tracking the location of a table surface, a computer-generated image can be placed on the table surface. Camera data can be used to track the movement of the user's hands, fingers, and / or other body parts in real time. In this way, hand gestures, finger gestures, and / or movements of other body parts (sometimes called air gestures) that function as user input can be used to control the operation of device 2.3-10 (for example, in a mixed reality or fully virtual environment).

[0950] Device 2.3-10 may have any suitable number of cameras, including three-dimensional cameras (e.g., structured light cameras, time-of-flight cameras, etc.), cameras for capturing real-world visible light images (e.g., for video passthrough), and / or cameras that perform tracking actions, function as part of a visual inertial odometry system, and / or otherwise support the operation of Device 2.3-10. The cameras of Device 2.3-10 may face forward, downward, sideways, upward, backward, and / or multiple directions. Some cameras may operate only in visible wavelengths. Other cameras may operate in visible and infrared wavelengths.

[0951] As described in relation to Figures 3 and 4, device 2.3-10 may, as an example, have one or more tracking cameras on each side of device 2.3-10. These cameras are highly sensitive to visible and infrared wavelengths and can be used for tracking operations (e.g., hand and body tracking, air gesture input tracking, accessory tracking), and optionally additional functions such as imaging structures in the user's environment for a visual inertial odometry system. The tracking cameras may be sensitive to visible and infrared wavelengths, such as wavelengths from 400–1000 nm, 400–740 nm, and 940 nm, or other suitable visible and infrared wavelengths. The infrared sensitivity of the tracking cameras preferably matches one or more wavelengths emitted by light source 2.3-58 in the auxiliary illumination system, allowing these cameras to operate when almost all or all available illumination is provided by light source 2.3-58 rather than ambient light.

[0952] If desired, the auxiliary lighting may be provided continuously. This specification describes, as an example, a configuration in which power is saved by interrupting the power supply to the auxiliary lighting system at least occasionally. In a configuration of device 2.3-10 in which the auxiliary lighting is turned on and off, device 2.3-10 may monitor for the occurrence of conditions indicating that the auxiliary lighting should be switched on for satisfactory operation of the camera (e.g., a tracking camera) during the operation of block 2.3-150. These monitoring activities may be performed while the camera (e.g., a tracking camera) of device 2.3-10 is operating normally without auxiliary lighting from the auxiliary lighting system.

[0953] Any suitable trigger criterion can be used to determine when to activate the auxiliary lighting system by turning on the light source 2.3-58. For example, device 2.3-10 may include an ambient light sensor. The ambient light sensor can measure the amount of visible ambient light present in the environment surrounding device 2.3-10. A threshold or other criterion can be applied to the ambient light reading from the ambient light sensor. Depending on whether the ambient light level is below a predetermined ambient light threshold, or otherwise too dim for satisfactory operation of the tracking camera, the control circuit 12 may turn on the light source 2.3-58 to provide auxiliary lighting (e.g., infrared light).

[0954] Another exemplary criterion that may be used in determining when to activate the auxiliary lighting includes evaluating an image processing algorithm quality metric. During the operation of block 2.3-150, the captured image may be processed by one or more image processing algorithms. These algorithms may include, as an example, a hand tracking algorithm. The hand tracking algorithm may generate a quality coefficient or other metric indicating the hand tracking algorithm's ability to satisfactorily track the user's hand. In response to detecting that the tracking algorithm quality metric is below a desired threshold, the control circuit 12 may turn on the light source 2.3-58 to provide auxiliary lighting to the camera.

[0955] If desired, the tracking camera or other image sensor hardware may provide information indicating that it is being negatively affected by low ambient light levels. For example, frames of image data may be evaluated to determine whether the lighting level is low. The output of the tracking camera hardware of device 2.3-10 may also indicate whether the signal-to-noise level is sufficient. If the tracking camera is generating only dark and / or noisy image data, the control circuit 12 may determine that the light source 2.3-58 should be turned on.

[0956] In some configurations, device 2.3-10 may be configured to determine the user's location relative to walls and other obstacles in the user's environment. For example, device 2.3-10 may include a map of known wall locations (e.g., a map obtained from an external source, or a map based on previous map-building operations performed by device 2.3-10 as the user walked around a building or other environment wearing device 2.3-10). Satellite navigation system circuitry (e.g., Global Positioning System circuitry) can use satellite signals to determine the location of device 2.3-10 (e.g., the location of device 2.3-10 relative to building walls and other obstacles). Using information about the user's known location and movement, and the locations of known obstacles such as walls, device 2.3-10 can predict when the user is likely to approach a wall or other obstacle. Sensors 16 within device 2.3-10 (such as proximity sensors, time-of-flight sensors, radar, and LiDAR) may also be used to monitor the user's movement relative to walls and other obstacles. By using some or all of this information in combination with additional information about the operating environment of device 2.3-10 (for example, ambient light readings indicating dim ambient lighting), device 2.3-10 can determine when light source 2.3-58 should be turned on to provide auxiliary lighting that helps ensure the tracking camera of device 2.3-10 operates satisfactorily. This can help ensure that the camera of device 2.3-10 can use the infrared illumination of light source 2.3-58 to track the location of obstacles in the user's environment. By accurately tracking the location of obstacles, warnings about these obstacles or their presence can be displayed on display 2.3-14 to help the user avoid undesirable collisions with obstacles.

[0957] If necessary, multiple electronic devices 2.3-10 within system 2.3-8 can monitor conditions indicating the need for auxiliary lighting. For example, multiple users may be wearing head-mounted devices, and one device may detect low levels of ambient light in front of another device. In this type of system, any of the devices detecting low levels of ambient light can signal other devices in the system requesting that auxiliary lighting be provided. In response, one or more of the other devices can provide auxiliary lighting to assist the requesting device's camera when acquiring images. Thus, auxiliary lighting systems of different devices can support each other by contributing to shared auxiliary lighting. This could allow a wall-mounted powered device to help provide auxiliary lighting for a battery-powered device, or allow an electronic device closer to the tracked object to provide auxiliary lighting to that object more efficiently than an electronic device further away from it (for example).

[0958] Unless conditions for triggering auxiliary lighting are detected, device 2.3-10 (e.g., control circuit 12) may continue to monitor for conditions that satisfy auxiliary lighting trigger criteria (e.g., dim ambient lighting, reduced tracking camera image processing quality, reduced camera hardware performance, criteria based on proximity of obstacles, requests from other devices, etc.) during the operation of block 2.3-150.

[0959] If the trigger criteria are met, processing may proceed to block 2.3-152. During the operation of block 2.3-152, control circuit 2.3-14 may use an auxiliary illumination system to provide auxiliary illumination for the camera (e.g., infrared light emitted by light sources 2.3-58 to illuminate external objects within the field of view of the tracking camera). When providing auxiliary illumination, the power of the infrared light emitted by each light source 2.3-58 and / or the direction of the light beam(s) emitted by each light source 2.3-58 may be adjusted. For example, some devices 2.3-70 may be turned on while others remain off, and the emitted light beams may be directed towards an area containing the object being tracked (e.g., the known location of the user's hand or other external object of interest being tracked by the tracking camera) and / or adjacent areas, and the emitted power level may be adjusted stepwise or continuously (e.g., so that sufficient auxiliary illumination is provided to ensure satisfactory tracking camera operation without providing excessive illumination).

[0960] Light sources such as light source 2.3-58 in Figures 2.3-5 and 2.3-6, configured to provide illumination over a fixed area, may be turned on to ensure that objects within those fixed areas are illuminated. Light sources that emit a maneuverable beam, such as light source 2.3-58 in Figures 2.3-5 and 2.3-8, may be used to emit auxiliary illumination over a relatively wide area (for example, by scanning the beam over a wide area, or by using multiple smaller beams simultaneously to illuminate different parts of a larger area), or they may be used to emit auxiliary illumination to a specific location, such as a location containing a tracked user's hand or other object.

[0961] Auxiliary lighting may be provided for cameras tracking parts of the user's body, cameras tracking the location of accessories, cameras capturing pass-through video, cameras forming part of a visual inertial odometry system, and / or other optical components that collect light from objects in the vicinity of device 2.3-10. If necessary, light sources 2.3-58 may be configured to emit structured light (e.g., features dispersed in lines, dots, or pseudo-random patterns). Structured light may be used, for example, in scenarios where a tracking camera collects three-dimensional images.

[0962] During the operation of block 2.3-152, device 2.3-10 may monitor conditions indicating that auxiliary lighting is no longer needed. Control circuit 2.3-12 may, for example, monitor to determine whether the auxiliary lighting trigger conditions are no longer met. As long as dim ambient lighting conditions or other conditions indicating that auxiliary lighting should be provided continue to exist, device 2.3-10 may continue to use light source 2.3-58 to provide auxiliary lighting. If the dim lighting conditions end, or if it is determined that other conditions for desired auxiliary lighting no longer exist, device 2.3-10 may turn off the auxiliary lighting system. In particular, control circuit 2.3-12 may turn off light source 2.3-58 during the operation of block 156. Operation may then return to block 2.3-150, as shown by line 2.3-152. 2.4: Systems having display and sensor concealment structures

[0963] Figure 2.4-1 is a front view of device 2.4-10 in an exemplary configuration in which device 2.4-10 has a publicly visible display such as a front display 2.4-14F. As shown in Figure 2.4-1, the support structure 2.4-16M of device 2.4-10 may have right and left parts such as parts 2.4-16R and 2.4-16L, which are joined by a nose bridge portion interposed between parts such as part 2.4-16NB. Part 2.4-16NB may have a curved outer surface such as a nose bridge surface 2.4-90 configured to receive and rest on the user's nose in order to help support the main housing portion 2.4-16M on the user's head.

[0964] The display 2.4-14F may have an active area such as an active area AA configured to display an image, and a non-active area IA that does not display an image. The contour of the active area AA may be rectangular, a rectangle with rounded corners, and may have teardrop-shaped portions on the left and right sides of the device 2.4-10, and may have a shape with straight edges, a shape with curved edges, a shape with periphery having both straight and curved portions, and / or other preferred contours. As shown in Figure 2.4-1, the active area AA may have a curved recess in the nose bridge portion 2.4-16NB of the main housing portion 2.4-16. The presence of a nose-shaped recess in the active area AA can help to fit the active area AA within the available space of the housing portion 2.4-16M without excessively limiting the size of the active area AA.

[0965] The active area AA includes an array of pixels. The pixels may be, for example, light-emitting diode pixels formed from thin-film organic light-emitting diodes or crystalline semiconductor light-emitting diode dies (sometimes called microlight-emitting diodes) on a flexible display panel substrate. Configurations in which display 2.4-14F uses other display technologies may also be used as needed. An exemplary configuration in which display 14 is formed from a light-emitting diode display, such as an organic light-emitting diode display, formed on a flexible substrate (for example, a substrate formed from a bendable layer of polyimide or a sheet of another flexible polymer), may also be described as an example herein. The pixels of the active area AA may be formed on a display device such as the display panel 2.4-14P (e.g., a flexible organic light-emitting diode display panel) of Figure 2.4-1. In some configurations, the contour of the active area AA (and, optionally, panel 2.4-14P) may have a periphery that includes straight segments or a combination of straight and curved segments. Configurations may also be used in which the entire contour of the active area AA (and optionally panel 2.4-14P) is characterized by a curved periphery.

[0966] Display 2.4-14F may have inactive areas, such as an inactive area IA, which has no pixels and does not display an image. The inactive area IA may form an inactive boundary region extending along one or more portions of the periphery of the active area AA. In the exemplary configuration of Figure 2.4-1, the inactive area IA has a ring shape that surrounds the active area AA and forms an inactive boundary. In this type of configuration, the width of the inactive area IA may be relatively constant, and the inner and outer edges of area IA may be characterized by straight and / or curved segments, or they may be curved along their entire length. For example, the outer edge of area IA (e.g., around display 2.4-14F) may have a curved contour extending parallel to the curved edge of the active area AA.

[0967] In some configurations, device 2.4-10 can operate in conjunction with other devices in system 2.4-8 (e.g., wireless controllers and other accessories). These accessories may have magnetic sensors that sense the direction and strength of a magnetic field. Device 2.4-10 may have one or more electromagnets configured to emit a magnetic field. The magnetic field can be measured by wireless accessories near device 2.4-10, so that the accessories can determine their orientation and position relative to device 2.4-10. This allows the accessories to function as wireless controllers, as they can wirelessly provide device 2.4-10 with real-time information about their current position, orientation, and movement. Accessories may include wearable devices, devices to be handled, and other input devices.

[0968] In an exemplary configuration, device 2.4-10 may have a coil such as exemplary coil 2.4-54 extending around the outer periphery of display 2.4-14F (e.g., under the inactive area IA or other parts of display 2.4-14F). Coil 2.4-54 may have any preferred number of windings (e.g., 1 to 10, at least 2, at least 5, at least 10, 10 to 50, less than 100, less than 25, less than 6, etc.). These windings may be formed from metal traces on a substrate, from wires, and / or from other conductive wires. During operation, control circuit 2.4-12 may supply an alternating current (AC) drive signal to coil 2.4-54. The drive signal may have a frequency of (for example) at least 1 kHz, at least 10 kHz, at least 100 kHz, at least 1 MHz, less than 10 MHz, less than 3 MHz, less than 300 kHz, or less than 30 kHz. When AC current flows through coil 2.4-54, a corresponding magnetic field is generated near device 2.4-10. An electronic device, such as a wireless controller with a magnetic sensor located near device 2.4-10, can use the magnetic field as a reference so that it can determine its orientation, position, and / or motion while the wireless controller is being moved relative to device 2.4-10 and provide input to device 2.4-10.

[0969] As an example, consider a handheld wireless controller used to control the operation of device 2.4-10. During operation, device 2.4-10 radiates a magnetic field using coil 2.4-54. As the handheld wireless controller is moved, the controller's magnetic sensor can monitor the controller's location and movement relative to device 2.4-10 by monitoring the strength, direction, and changes in strength and / or direction of the magnetic field radiated by coil 2.4-54 as the controller is moved through the air by the user. The electronic device can then wirelessly transmit information about the controller's location and orientation to device 2.4-10. In this way, the handheld controller, wearable controller, or other external accessory can be operated by the user to provide air gestures, pointing inputs, steering inputs, and / or other user inputs to device 2.4-10.

[0970] Device 2.4-10 may have components such as optical components (e.g., the optical sensor among the sensors 2.4-16 in Figure 2.4-1). These components may be mounted at any suitable location on the head-mount support structure 2.4-16 (e.g., on the head strap 2.4-16B, on the main housing portion 2.4-16M, etc.). The optical components and other components may be mounted facing backward (e.g., when mounted on the rear surface of device 2.4-10), to the side (e.g., left or right), downward or upward, to the front of device 2.4-10 (e.g., when mounted on the front surface of device 2.4-10), to point in any combination of these directions (e.g., forward, to the right, and downward), and / or in other suitable orientations. In an exemplary configuration, at least some of the components of device 2.4-10 are mounted facing forward (and optionally to the side and / or up and down). For example, forward-facing cameras for pass-through video may be mounted on the left and right sides of the front of device 2.4-10 in a configuration where the cameras are slightly branched along the horizontal dimension, and the fields of view of these cameras overlap to some extent while capturing wide-angle images of the environment in front of device 2.4-10. The captured images may, if necessary, include portions of the user's surroundings below, above, and to the sides of the area directly in front of device 2.4-10.

[0971] To help conceal components such as optical components from view from the outside of device 2.4-10, it may be desirable to cover some or all of the components with a decorative cover structure. The cover structure may include transparent portions (e.g., optical component windows) characterized by sufficient light transmittance to allow the overlapping optical components to function satisfactorily. For example, an ambient light sensor may be covered with a layer that appears opaque to an external observer to help conceal the ambient light sensor from view, but allows sufficient ambient light to pass through the ambient light sensor for it to perform satisfactory ambient light measurements. As another example, an optical component that emits infrared light may be superimposed with a visually opaque material that is transparent to infrared light.

[0972] In an exemplary configuration, the optical components for device 2.4-10 may be mounted within the inactive area IA in Figure 2.4-1, and the decorative cover structure may be formed in a ring shape overlapping the optical components within the inactive area IA. The decorative cover structure may be formed from ink, polymer structures, metal-containing structures, glass, other materials, and / or combinations of these materials. In an exemplary configuration, the decorative cover structure may be formed from a ring-shaped member having a footprint that matches the footprint of the inactive area IA. For example, if the active area AA has left and right portions having a teardrop shape, the ring-shaped member may have curved edges that follow the curved outer perimeter of the teardrop-shaped portion of the active area AA. The ring-shaped member may be formed from one or more polymer structures (for example, the ring-shaped member may be formed from a polymer ring). Since the ring-shaped member can help to conceal the overlapping components from view, the ring-shaped member is sometimes called a shroud or ring-shaped shroud member. The appearance of the shroud or other decorative cover structure may be characterized by achromatic colors (white, black, or gray) or non-chromatic colors (e.g., blue, red, green, gold, rose gold, etc.).

[0973] Display 2.4-14F may have a protective display cover layer, if necessary. The cover layer may overlap the active area AA and the inactive area IA (for example, the entire front surface of device 2.4-10 as viewed from direction 2.4-52 in Figure 2.4-1 may be covered by the cover layer). The cover layer, sometimes called a housing wall or transparent housing wall, may have a rectangular contour, a contour with a teardrop portion, an elliptical contour, or other shapes with curved and / or straight edges.

[0974] The cover layer can be formed from transparent materials such as glass, polymers, transparent crystalline materials such as sapphire, transparent ceramics, other transparent materials, and / or combinations thereof. As an example, a protective display cover layer for display 2.4-14F may be formed from safety glass (e.g., laminated glass including a transparent glass layer with a laminated polymer film). An optional coating layer may be applied to the surface of the display cover layer. If necessary, the display cover layer may be chemically strengthened (e.g., using an ion exchange process to create an outer layer of material under compressive stress that can withstand scratches). In some configurations, the display cover layer may be formed from a stack of two or more material layers (e.g., a first structural glass layer and a second structural glass layer, a glass layer, or a rigid polymer layer bonded to another rigid polymer layer) to improve the performance of the cover layer.

[0975] In the active area AA, the display cover layer may overlap the pixels of the display panel 2.4-14P. The display cover layer in the active area AA is preferably transparent so that the image presented on the display panel 2.4-14P can be viewed. In the inactive area IA, the display cover layer may overlap a ring-shaped shroud or other decorative cover structure. The shroud and / or other cover structure (e.g., an opaque ink coating on the inner surface of the display cover layer and / or structure) may be sufficiently opaque to help conceal some or all of the optical components in the inactive area IA from view. Windows may be provided in the shroud or other decorative cover structure to help ensure that the optical components on which these structures overlap function satisfactorily. The windows may be formed from holes, from areas of the shroud or other decorative cover structure that are locally thinned to increase light transmission, from window members having desired light transmission properties inserted into a fitting opening in the shroud, and / or from other shroud window structures.

[0976] In the example shown in Figure 2.4-1, device 2.4-10 includes optical components such as (as an example) optical components 2.4-60, 2.4-62, 2.4-64, 2.4-66, 2.4-68, 2.4-70, 2.4-72, 2.4-74, 2.4-76, 2.4-78, and 2.4-80. Each of these optical components (e.g., an optical sensor selected from sensor 2.4-16 in Figure 2.4-1, a light-emitting device, etc.) may be configured to detect light and, if necessary, emit light (e.g., ultraviolet light, visible light, and / or infrared light).

[0977] In an exemplary configuration, optical component 2.4-60 can sense ambient light (e.g., visible ambient light). In particular, optical component 2.4-60 may have a photodetector that senses changes in ambient light intensity as a function of time. For example, if the user is operating in an environment with an artificial light source, the light source may emit light at a frequency associated with its wall power supply (e.g., a 60 Hz AC mains power supply). The photodetector of component 2.4-60 can sense that the artificial light from the artificial light source is characterized by a 60 Hz intensity fluctuation. The control circuit 2.4-12 can use this information to adjust the clock or other timing signals associated with the operation of the image sensor in device 2.4-10 to help avoid undesirable interference between the light source frequency and the frame rate or other frequencies associated with the image capture operation. The control circuit 2.4-12 can also use measurements from component 2.4-60 to help identify the presence and type of artificial lighting present. In this way, the control circuit 2.4-12 can detect the presence of light, such as fluorescent lamps or other light with known non-ideal color characteristics, and can perform corrective color cast adjustment (e.g., white point adjustment) for color-sensitive components such as cameras and displays. Since the optical component 2.4-60 can measure fluctuations in light intensity, component 2.4-60 is sometimes called a flicker sensor or ambient light frequency sensor.

[0978] Optical component 2.4-62 may be an ambient light sensor. The ambient light sensor may include one or more photodetectors. In a single photodetector configuration, the ambient light sensor may be a monochromator that measures ambient light intensity. In a multi-photodetector configuration, each photodetector may have superimposed optical filters that allow different wavelength bands (e.g., different visible and / or infrared passbands). The optical filter passbands may overlap at their edges. This allows component 2.4-62 to function as a color ambient light sensor that measures both ambient light intensity and ambient light color (e.g., by measuring the color coordinates of the ambient light). During the operation of device 2.4-10, the control circuit 2.4-12 may take action based on the measured ambient light intensity and color. For example, the white point of a display or image sensor may be adjusted based on the measured ambient light color, or the color of another display or image sensor may be adjusted. The intensity of the display may be adjusted based on the light intensity. For example, the brightness of display 2.4-14F may be increased in bright ambient lighting conditions to improve the visibility of images on the display, and the brightness of display 2.4-14F may be reduced in dim lighting conditions to conserve power. Image sensor operation and / or light source operation may also be adjusted based on ambient light readings.

[0979] Optical components within the active area IA may also include components along the sides of device 2.4-10, such as components 2.4-80 and 2.4-64. Optical components 2.4-80 and 2.4-64 may be pose-tracking cameras used to help monitor the orientation and motion of device 2.4-10. Components 2.4-80 and 2.4-64 may also be visible light cameras (and / or cameras that sense visible and infrared wavelengths) and, together with an inertial measurement unit, can form a visual inertial odometry (VIO) system.

[0980] Optical components 2.4-78 and 2.4-66 may be visible light cameras that capture real-time images of the environment surrounding device 2.4-10. Sometimes called scene cameras or pass-through video cameras, these cameras can capture video that is displayed in real time on display 2.4-14R for the user to see when the user's eyes are positioned inside the rear eye box 2.4-24 of device 2.4-10. In this way, by displaying pass-through images (pass-through video) to the user, real-time information about the user's surroundings can be provided to the user. If necessary, virtual content (e.g., computer-generated images) may be overlaid on a portion of the pass-through video. Device 2.4-10 can also operate in a non-pass-through video mode, where components 2.4-78 and 2.4-66 are turned off, and the user is provided with only other virtual content that does not include movie content, game content, and / or real-time real-world images.

[0981] The input / output device 2.4-12 of device 2.4-10 can collect user input used to control the operation of device 2.4-10. For example, the microphone within device 2.4-10 can collect voice commands. Buttons, touch sensors, force sensors, and other input devices can collect user input from the user's fingers or other external objects in contact with device 2.4-10. In some configurations, it may be desirable to monitor the user's hand gestures or the movements of other user body parts. This allows the location of the user's hands or other body parts to be replicated in the game or other virtual environment, and the user's hand movements can function as hand gestures (air gestures) to control the operation of device 2.4-10. User input, such as hand gesture input, can be captured using cameras operating in visible and infrared wavelengths, such as tracking cameras (e.g., optical components 2.4-76 and 2.4-68). Such tracking cameras can also track reference points and other recognizable features on the controllers and other external accessories (additional devices 2.4-10 of system 2.4-8) while these controllers are being used to control the operation of device 2.4-10. If necessary, the tracking camera can help determine the position and orientation of a handheld or wearable controller, sensing its location and orientation by measuring the magnetic field generated by coil 2.4-54. Thus, the use of tracking cameras can help track hand movements and controller movements used to move pointers and other virtual objects displayed to the user, and otherwise help control the operation of device 2.4-10.

[0982] The tracking camera can operate satisfactorily in the presence of sufficient ambient light (e.g., bright visible ambient illumination conditions). In dim environments, auxiliary illumination can be provided by auxiliary light sources such as auxiliary infrared light sources (e.g., optical components 2.4-82 and 2.4-84). Each infrared light source may include one or more light-emitting devices (light-emitting diodes or lasers), each configured to provide a fixed and / or maneuverable beam of infrared light that serves as auxiliary illumination for the tracking camera. If necessary, the infrared light sources may be turned off in bright ambient illumination conditions (e.g., using the ambient light sensing capability of optical component 2.4-82) and turned on in response to the detection of dim ambient light.

[0983] The three-dimensional sensors within device 2.4-10 may be used to perform biometric identification operations (e.g., facial recognition for authentication), to determine the three-dimensional shape of objects in the user's environment (e.g., to map the user's environment so that a matching virtual environment can be created for the user), and / or to collect three-dimensional content during the operation of device 2.4-10. As an example, optical components 2.4-74 and 2.4-70 may be three-dimensional structured light imaging sensors. Each three-dimensional structured light imaging sensor may have one or more light sources that provide structured light (e.g., a dot projector that projects an array of infrared dots onto the environment, a structured light source that generates a grid of lines, or other structured light components that emit structured light). Each three-dimensional structured light imaging sensor may also include a light source (e.g., a light-emitting diode or laser that emits a broad beam of infrared light). Using floodlighting and structured lighting, optical components 2.4-74 and 2.4-70 can capture facial images, images of objects in the environment surrounding device 2.4-10, and the like.

[0984] Optical component 2.4-72 may be an infrared three-dimensional time-of-flight camera that uses time-of-flight measurement for emitted light to collect three-dimensional images of objects in the environment surrounding device 2.4-10. Component 2.4-72 may have a longer range and narrower field of view than the three-dimensional structured optical cameras of optical components 2.4-74 and 2.4-70. The operating range of component 2.4-72 may be (for example) 30cm to 7m, 2.4-60cm to 6m, 70cm to 5m, or other preferred operating ranges. 2.5: System having a cover layer sealing structure

[0985] A head-mounted device may include a head-mounted support structure that allows the device to be mounted on the user's head. The head-mounted device may have a display supported by the head-mounted support structure for presenting visual content to the user. The display may include a rear display that presents images to an eyebox at the rear of the head-mounted support structure. The display may also include a front display. The front display may be mounted on the front of the head-mounted support structure and may be visible to the user when the head-mounted device is not mounted on the user's head. The front display, sometimes referred to as a publicly visible display, may also be visible to other people in the vicinity of the head-mounted device.

[0986] Optical components, such as image sensors and other light sensors, may be provided within the head-mounted device. In an exemplary configuration, the optical components are mounted beneath the peripheral portion of the display cover layer that protects the front display. The display cover layer, or other layers within the head-mounted device, may be formed from a material such as shatterable glass. Since the head-mounted device is close to the user's eyes during operation, it may be desirable to reduce the possibility of these layers entering the user's eyes. Therefore, laminates, such as plastic laminates, may be formed on the top and bottom surfaces of the cover layer. To protect the edges of the cover layer, encapsulating material may be bonded to the edge surface, or the head-mounted device housing structure may be modified to reduce the possibility of glass from the cover layer protruding from the device.

[0987] Figure 2.5-1 is a side view of an exemplary head-mounted electronic device. As shown in Figure 2.5-1, the head-mounted device 2.5-10 may include a head-mounted support structure 2.5-26. The support structure 2.5-26 may have walls or other structures that separate the internal regions of the device 2.5-10, such as the internal region 2.5-42, from the external regions surrounding the device 2.5-10, such as the external region 2.5-44. Electrical components 2.5-40 (e.g., integrated circuits, sensors, control circuits, light-emitting diodes, lasers, and other light-emitting devices, other control circuits, and input / output devices) may be mounted on printed circuits and / or other structures within the device 2.5-10 (e.g., within the internal region 2.5-42).

[0988] To present the user with an image to be viewed from an eyebox such as eyebox 2.5-34, device 2.5-10 may include a rear display such as display 2.5-14R, which may have associated lenses for focusing the image for viewing within the eyebox. These components can be mounted within an optical module (e.g., a lens barrel) to form the respective left and right optical systems. For example, there may be a left rear display for presenting an image to the user's left eye through the left lens in the left eyebox, and a right rear display for presenting an image to the user's right eye in the right eyebox. The user's eyes are located within the eyebox 2.5-34 on the rear side R of device 2.5-10 when the structure 2.5-26 is positioned relative to the outside of the user's face.

[0989] Support structure 2.5-26 may include a main support structure (sometimes called a main part or housing). The main housing support structure may extend from the front F of device 2.5-10 to the rear R opposite side of device 2.5-10. At the rear R, support structure 2.5-26 may have a cushioning structure to improve user comfort when support structure 2.5-26 is placed against the user's face. Optionally, support structure 2.5-26 may include an optional head strap and / or other structures that enable device 2.5-10 to be attached to the user's head.

[0990] Device 2.5-10 may have a publicly visible, forward-facing display, such as a display 2.5-14F, mounted on the front side F of a support structure 2.5-26. The display 2.5-14F may be visible to the user when the user is not wearing device 2.5-10, and / or may be visible to others in the vicinity of device 2.5-10. For example, the display 2.5-14F may be visible on the front side F of device 2.5-10 by an external observer viewing device 2.5-10 from the front F.

[0991] A schematic diagram of an exemplary system that may include a head-mounted device is shown in Figure 2.5-2. As shown in Figure 2.5-2, system 2.5-8 may include one or more electronic devices 2.5-10. Devices 2.5-10 may include a head-mounted device (e.g., device 2.5-10 in Figure 2.5-1), accessories such as controllers and headphones, computing equipment (e.g., a cellular phone, a tablet computer, a laptop computer, a desktop computer, and / or remote computing equipment that supplies content to the head-mounted device), and / or other devices that communicate with each other.

[0992] Each electronic device 2.5-10 may have a control circuit 2.5-12. The control circuit 2.5-12 may include storage and processing circuits that control the operation of the device 2.5-10. The circuit 2.5-12 may include storage such as a hard disk drive, non-volatile memory (e.g., electrically programmable read-only memory configured to form a solid-state drive), or volatile memory (e.g., static or dynamic random-access memory). The processing circuits of the control circuit 2.5-12 may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, graphics processing units, application-specific integrated circuits, and other integrated circuits. Software code is stored on the storage within the circuit 2.5-12 and executed on the processing circuits within the circuit 2.5-12 to perform control operations of the device 2.5-10 (e.g., data acquisition operations, operations including adjustment of components of the device 2.5-10 using control signals, etc.). The control circuit 2.5-12 may include wired communication circuits and wireless communication circuits. For example, control circuit 2.5-12 may include wireless transceiver circuits such as cellular telephone transceiver circuits, wireless local area network transceiver circuits (e.g., WiFi® circuits), millimeter-wave transceiver circuits, and / or other wireless communication circuits.

[0993] During operation, communication between electronic devices can be supported using the communication circuits of devices within System 2.5-8 (for example, the communication circuit of the control circuit 2.5-12 of device 2.5-10). For example, one electronic device can transmit video data, audio data, control signals, and / or other data to another electronic device within System 2.5-8. Electronic devices within System 2.5-8 can communicate over one or more communication networks (e.g., the Internet, a local area network, etc.) using wired and / or wireless communication circuits. The communication circuits can be used to enable device 2.5-10 to receive data from and / or provide data to external devices (e.g., portable devices such as tethered computers, handheld devices, or laptop computers, online computing devices such as remote servers or other remote computing equipment, or other electrical equipment).

[0994] Each device 2.5-10 in system 2.5-8 may include an input / output device 2.5-22. The input / output device 2.5-22 can be used to enable a user to provide user input to device 2.5-10. The input / output device 2.5-22 may also be used to collect information about the environment in which device 2.5-10 is operating. Output components within device 2.5-22 can enable device 2.5-10 to provide output to a user and can be used for communication with external electrical equipment.

[0995] As shown in Figure 2.5-2, the input / output device 2.5-22 may include one or more displays, such as display 2.5-14. Display 2.5-14 may include a rear display, such as display 2.5-14R in Figure 2.5-1. Device 2.5-10 may include left and right components, such as left and right scanning mirror display devices or other image projectors, liquid crystal on silicon display devices, digital mirror devices or other reflective display devices, left and right display panels based on light-emitting diode pixel arrays (e.g., thin-film organic light-emitting displays having polymer or semiconductor substrates such as silicon substrates, or display devices based on pixel arrays formed from crystalline semiconductor light-emitting diode dies), liquid crystal display panels, and / or other left and right display devices that provide images to left and right eye boxes for viewing by the user's left and right eyes, respectively. Such display components (e.g., thin-film organic light-emitting displays having a flexible polymer substrate, or displays based on pixel arrays formed from crystalline semiconductor light-emitting diode dies on a flexible substrate) can also be used to form front displays (sometimes called front-facing displays, front displays, or publicly visible displays) for devices 2.5-10, such as the front display 2.5-14F in Figure 2.5-1.

[0996] During operation, displays 2.5-14 (e.g., displays 2.5-14R and / or 2.5-14F) may be used to display visual content for the user of device 2.5-10 (e.g., still images and / or videos, including photographs and pass-through videos from camera sensors, text, graphics, movies, games, and / or other visual content). The content presented on display 2.5-14 may include, for example, virtual objects and other content provided to display 2.5-14 by control circuit 2.5-12. This virtual content is sometimes referred to as computer-generated content. Computer-generated content may be displayed when there is no real-world content, or it may be combined with real-world content. In some configurations, real-world images may be captured by a camera (e.g., a front-facing camera, sometimes referred to as a front camera), and computer-generated content may be electronically overlaid on a portion of the real-world image (e.g., when device 2.5-10 is a pair of virtual reality goggles).

[0997] The input / output circuit 2.5-22 may include a sensor 2.5-16. Examples of sensors 2.5-16 include a three-dimensional sensor (for example, a three-dimensional image sensor such as a structured light sensor that emits a light beam and uses a two-dimensional digital image sensor to collect image data for a three-dimensional image from dots or other light spots generated when a target is illuminated by the light beam), a binocular three-dimensional image sensor that collects three-dimensional images using two or more cameras in a binocular imaging configuration, a three-dimensional lidar (light detection and ranging (LIDAR) sometimes called a time-of-flight camera or three-dimensional time-of-flight camera) Examples of sensors include: (ranging)) sensors, three-dimensional high-frequency sensors, or other sensors that collect three-dimensional image data), cameras (e.g., two-dimensional infrared and / or visible digital image sensors), eye-tracking sensors (e.g., eye-tracking systems based on image sensors, and, if necessary, light sources that emit one or more light beams that are tracked using the image sensor after being reflected from the user's eye), touch sensors, capacitive proximity sensors, light-based (optical) proximity sensors, other proximity sensors, force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors, etc.), sensors such as switch-based contact sensors, gas sensors, pressure sensors, humidity sensors, magnetic sensors, audio sensors (microphones), ambient light sensors, flicker sensors that collect temporal information about ambient lighting conditions such as the presence of time-varying ambient light related to artificial lighting, microphones for collecting voice commands and other voice inputs, sensors configured to collect information about motion, position, and / or orientation (e.g., accelerometers, gyroscopes, compasses, and / or inertial measurement units that include all of these sensors or a subset of one or two of these sensors), and / or other sensors.

[0998] User input and other information may be collected using sensors and other input devices within input / output device 2.5-22. Optionally, input / output device 2.5-22 may include other devices 2.5-24 such as tactile output devices (e.g., vibration components), light-emitting diodes, lasers, and other light sources (e.g., light-emitting devices that emit light to illuminate the environment surrounding device 2.5-10 when ambient light levels are low), speakers such as ear speakers for generating audio output, circuits for receiving wireless power, circuits for wirelessly transmitting power to other devices, batteries and other energy storage devices (e.g., capacitors), joysticks, buttons, and / or other components.

[0999] As described in relation to Figure 2.5-1, the electronic device 2.5-10 may have a head-mount support structure such as the head-mount support structure 2.5-26 (e.g., a head-mount housing structure such as a housing wall or strap). The head-mount support structure may be configured to be attached to the user's head (e.g., relative to the user's face, covering the user's eyes) during the operation of the device 2.5-10, and may support the display 2.5-14, the sensor 2.5-16, other components 2.5-24, other input / output devices 2.5-22, and the control circuit 2.5-12 (e.g., including an associated optical module, see component 2.5-40 and displays 2.5-14R and 2.5-14F in Figure 2.5-1).

[1000] Figure 2.5-3 is a front view of device 2.5-10 in an exemplary configuration in which device 2.5-10 has a publicly visible display such as a front display 2.5-14F. As shown in Figure 2.5-3, the support structure 2.5-26 of device 2.5-10 may have right and left portions on either side of the nose bridge 2.5-90. The nose bridge 2.5-90 may have a curved outer surface configured to receive and rest on the user's nose in order to help support the housing 2.5-26 on the user's head.

[1001] The display 2.5-14F may have an active area such as an active area AA configured to display an image, and a non-active area IA that does not display an image. The contour of the active area AA may be rectangular, a rectangle with rounded corners, and may have teardrop-shaped portions on the left and right sides of the device 2.5-10, and may have a shape with straight edges, a shape with curved edges, a shape with periphery having both straight and curved portions, and / or other preferred contours. As shown in Figure 2.5-3, the active area AA may have a curved recess in the nose bridge 2.5-90. The presence of a nose-shaped recess in the active area AA can help to fit the active area AA within the available space of the housing 2.5-26 without excessively limiting the size of the active area AA.

[1002] The active area AA includes an array of pixels. The pixels may be, for example, light-emitting diode pixels form...
