[0910] Figure 15-6B This shows a sample user interface displayed by the HMD's display module. Detailed Implementation

[0911] I: Overall System

[0912] Figure 1-1AA front top perspective view illustrates an example of a head-mounted display (HMD) device 1-100 configured to be worn by a user and to provide a virtual and altered / mixed reality (VR / AR) experience. The HMD 1-100 may include a display unit 1-102 or component, an electronic strip assembly 1-104 connected to and extending from the display unit 1-102, and a strap assembly 1-106 secured at either end to the electronic strip assembly 1-104. The electronic strip assembly 1-104 and the strap 1-106 may be part of a retention assembly configured to wrap around the user's head to hold the display unit 1-102 against the user's face.

[0913] In at least one example, the band assembly 1-106 may include a first band 1-116 configured to wrap around the back of the user's head and a second band 1-117 configured to extend over the top of the user's head. As shown, the second band may extend between the first electronic band 1-105a and the second electronic band 1-105b of the electronic band assembly 1-104. The band assembly 1-104 and the band assembly 1-106 may be part of a fixing mechanism that extends rearward from the display unit 1-102 and is configured to hold the display unit 1-102 against the user's face.

[0914] In at least one example, the fixing mechanism includes a first electronic strip 1-105a, which includes a first proximal end 1-134 coupled to a display unit 1-102 (e.g., a housing 1-150 of the display unit 1-102) and a first distal end 1-136 opposite to the first proximal end 1-134. The fixing mechanism may also include a second electronic strip 1-105b, which includes a second proximal end 1-138 coupled to the housing 1-150 of the display unit 1-102 and a second distal end 1-140 opposite to the second proximal end 1-138. The fixing mechanism may also include a first strip 1-116 and a second strip 1-117, the first strip including a first end 1-142 coupled to the first distal end 1-136 and a second end 1-144 coupled to the second distal end 1-140, and the second strip extending between the first electronic strip 1-105a and the second electronic strip 1-105b. Strips 1-105a to 1-105b and strip 1-116 may be coupled via a connecting mechanism or component 1-114. In at least one example, the second strip 1-117 includes a first end 1-146 coupled to the first electronic strip 1-105a between a first proximal end 1-134 and a first distal end 1-136, and a second end 1-148 coupled to the second electronic strip 1-105b between a second proximal end 1-138 and a second distal end 1-140.

[0915] In at least one example, the first electronic strip 1-105a and the second electronic strip 1-105b comprise plastic, metal, or other structural materials forming the substantially rigid shape of the strips 1-105a to 1-105b. In at least one example, the first strip 1-116 and the second strip 1-117 are formed of an elastic flexible material (including woven textiles, rubber, etc.). The first strip 1-116 and the second strip 1-117 may be flexible enough to conform to the shape of the user's head when the HMD 1-100 is worn.

[0916] In at least one example, one or more of the first electronic stripe 1-105a and the second electronic stripe 1-105b may define an inner stripe volume and include one or more electronic components disposed within the inner stripe volume. In one example, such as Figure 1-1A As shown, the first electronic strip 1-105a may include electronic components 1-112. In one example, electronic components 1-112 may include a speaker. In another example, electronic components 1-112 may include computing components, such as a processor.

[0917] In at least one example, the housing 1-150 defines a first front opening 1-152. The front opening is located in... Figure 1-1A The area 1-152 is indicated by a dashed line because the front display assembly 1-108 is configured to obscure the first opening 1-152 from view when the HMD 1-100 is assembled. The housing 1-150 may also define a rearward second 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 disposed in or across the front opening 1-152 to obscure the front opening 1-152, and a display screen (shown in other figures). In at least one example, the display screen of the display assembly 1-108, and the display assembly 1-108 as a whole, have a curvature configured to conform to the curvature of the user's face. The display screen of display component 1-108 can be bent as shown to complement the user's facial features and the overall curvature from one side of the face to the other (e.g., from left to right and / or from top to bottom when the display unit 1-102 is pressed).

[0918] 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 1-126 disposed in the first aperture 1-128, and a second button 1-132 disposed in the second aperture 1-130. The first button 1-128 and the second button 1-132 may be pressed down through the corresponding 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 rotary dial and a pressable button. In at least one example, the first button 1-126 is a pressable and rotary dial button, and the second button 1-132 is a pressable button.

[0919] Figure 1-1B A rear perspective view of HMD 1-100 is illustrated. HMD 1-100 may include a light seal 1-110 extending rearwardly around the periphery of housing 1-150 of display assembly 1-108, as shown. The light seal 1-110 may be configured to extend from housing 1-150 around the user's eyes to the user's face to block external light from being visible. In one example, HMD 1-100 may include a first display assembly 1-120a and a second display assembly 1-120b disposed at or within a rearward second opening 1-154 defined by housing 1-150 and / or disposed within an internal volume of housing 1-150 and configured to project light through the second opening 1-154. In at least one example, each display assembly 1-120a to 1-120b may include a corresponding display screen 1-122a, 1-122b configured to project light toward the user's eyes in a rearward direction through the second opening 1-154.

[0920] In at least one example, reference Figure 1-1A and Figure 1-1B Both, the display assembly 1-108 may be a front-facing display assembly including a display screen configured to project light in a first forward direction, and the rear displays 1-122a to 1-122ab may be configured to project light in a second rearward direction opposite to the first direction. As noted above, the light seal 1-110 may be configured to block light from outside the HMD 1-100 from reaching the user's eyes, the light including light from... Figure 1-1AThe front perspective view shows the light projected onto the front display screen by the display assembly 1-108. In at least one example, the HMD 1-100 may also include a curtain 1-124 that blocks the second opening 1-154 between the housing 1-150 and the rear display assemblies 1-120a to 1-120b. In at least one example, the curtain 1-124 may be elastic or at least partially elastic.

For example, HMD 1-200 may include a strip 1-216 that may be selectively coupled to a first electronic strip 1-205a and a second electronic strip 1-205b. The first fixed strip 1-205a may include a first electronic component 1-212a, and the second fixed strip 1-205b may include a second electronic component 1-212b. In at least one example, the first strip 1-205a and the second strip 1-205b may be removably coupled to a display unit 1-202.

[0923] Furthermore, HMD 1-200 may include a light-sealing member 1-210 configured to be removably coupled to display unit 1-202. HMD 1-200 may also include a lens 1-218, which may be removably coupled to display unit 1-202, for example, over a first display assembly and a second display assembly including a display screen. Lens 1-218 may include a custom prescription lens configured for vision correction. As noted, Figure 1-2 As shown in the view and described above, each component can be removably coupled, attached, reattached, and replaced to update the component or to replace it for different users. For example, belts such as belt 1-216, light seals such as light seal 1-210, lenses such as lens 1-218, and electronic strips such as electronic strips 1-205a to 1-205b can be replaced according to the user, so that these components are customized to fit and correspond to the individual user of HMD 1-200.

[0932] II: Covering Glass

[0933] Figure 2.0-1An illustration shows a view of an HMD 2.0-100 including a front cover and display assembly 2.0-102, which includes one or more clear layers, a display integration assembly, a shield, and a dust seal. The clear layers, display assembly, shield, and dust seal are described below in sections II, III, IV, and V.

[0934] 2.1: Systems with transparent layers

[0935] Transparent layers can be used to form windows in buildings, vehicles, and / or other systems. They can also be used to form protective coverings, such as those for optical components.

[0936] Figure 2.1-1 It is a cross-sectional side view of an exemplary system that includes a transparent layer. Figure 2.1-1 System 2.1-10 has a support, such as support 2.1-12, in which one or more transparent layers, such as transparent layer 2.1-14, can be mounted. System 2.1-10 can be a building (e.g., support 2.1-12 may include a building wall), can be a vehicle (e.g., support 2.1-12 may be a vehicle body), can be an electronic device (e.g., support 2.1-12 may be an electronic device housing, such as a head-mounted housing for a head-mounted device), and / or can be any other suitable system. In an arrangement where system 2.1-10 is a building or vehicle, layer 2.1-14 can act as a window. In an arrangement where system 2.1-10 is an electronic device, layer 2.1-14 can overlap with and protect components in the device. For example, layer 2.1-14 can act as a protective cover layer overlapping optical components. In an exemplary configuration, system 2.1-10 is a portable electronic device (e.g., a cellular phone, a head-mounted device, a tablet computer, a laptop computer, a wristwatch, etc.).

[0937] Transparent layer 2.1-14 and support member 2.1-12 separate the inner region 2.1-16 of system 2.1-10 from the outer region 2.1-18. System components can be mounted in the inner 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 outer region 2.1-18, and the inner surface of layer 2.1-14 may face the inner region 2.1-16. The surfaces of layer 2.1-14 may include planar portions and / or curved portions. For example, layer 2.1-14 may have a shape including a curved cross-sectional profile, such as shape 2.1-20. In an arrangement in which layer 2.1-14 is curved, the inner and outer surfaces may be parallel to each other (e.g., the thickness of layer 2.1-14 across layer 2.1-14 may be constant). If desired, some or all of the surfaces of layer 2.1-14 may have composite curvature (surfaces that can only be flattened into a plane under distortion). The surface region of composite curvature can surround Figure 2.1-1 Both the X-axis and Y-axis are bent.

[0938] Figure 2.1-2 This illustrates how layer 2.1-14 can overlap with components such as illustrative components 2.1-20 and 2.1-22 in the inner regions 2.1-16. Components 2.1-20 and 2.1-22 may include optical components that emit and / or detect light. As an example, component 2.1-22 may be a display that emits visible light through layer 2.1-14. This allows a viewer in the outer region 2.1-18 to view an image on the display through layer 2.1-14 (e.g., layer 2.1-14 may act as a display overlay). 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. Figure 2.1-2 The overlapping components 2.1-20 and 2.1-22 shown, layer 2.1-14 can serve as a protective covering layer for components 2.1-20 and 2.1-22.

[0939] During events such as a drop in which system 2.1-10 suddenly contacts the ground or other hard surfaces, layer 2.1-14 may be subjected to a large amount of undesirable stress. To help enhance durability, layer 2.1-14 may be provided with one or more polymer layers. As an example, polymer layers may be used to laminate multiple transparent material layers together, and / or polymer layers may be formed on the exposed inner and / or outer surfaces of layer 2.1-14.

[0940] Figure 2.1-3 This is a cross-sectional side view of layer 2.1-14. (As shown) Figure 2.1-3As shown, layers 2.1-14 may include multiple transparent material layers, such as layers 2.1-40, 2.1-34, 2.1-32, and 2.1-30. In an exemplary configuration, layer 2.1-14 includes two hard transparent material layers and one or more softer layers attached to the harder layers. The softer layers may be, for example, polymer layers that help enhance durability.

[0941] exist Figure 2.1-3 In the examples, layers 2.1-34 can be hard layers, such as glass (including glass-ceramic) layers, sapphire layers, or other crystalline material layers. In this document, exemplary configurations in which layers 2.1-34 are glass layers may sometimes be described as examples. Layers 2.1-34 may be formed of aluminosilicate glass or other glass materials and may optionally be chemically strengthened using an ion-exchange chemical strengthening process that compresses the surfaces of layers 2.1-34 relative to the core of layers 2.1-34. Layers 2.1-34 may have a thickness sufficient to provide some or all of the structural strength of layers 2.1-14; therefore, layers 2.1-34 may sometimes be referred to as structural layers, structural transparent layers, or structural glass layers. As an example, layers 2.1-34 may have a thickness of 700 micrometers, at least 400 micrometers, at least 500 micrometers, at least 600 micrometers, less than 1200 micrometers, less than 1000 micrometers, less than 900 micrometers, less than 800 micrometers, 400 to 1200 micrometers, 400 to 1100 micrometers, 400 to 1000 micrometers, 400 to 800 micrometers and / or other suitable thicknesses.

[0942] One or more polymer layers may be attached to layers 2.1-34. In an exemplary configuration, polymer layers 2.1-40 are attached to the inner surfaces 2.1-42 of layers 2.1-34. Layers 2.1-40 may include a first layer such as layer 2.1-38 and a second layer such as layer 2.1-36. Layers 2.1-38 may be polymer films (e.g., polycarbonate films, polyethylene terephthalate films, or other polymer films) and may have a thickness of 50 micrometers, 10 to 250 micrometers, 25 to 100 micrometers, at least 20 micrometers, less than 200 micrometers, less than 150 micrometers, or other suitable thicknesses. Layers 2.1-36 may be polymer layers, such as polymer adhesives (e.g., epoxy resins, acrylic adhesives, curing liquid adhesives, pressure-sensitive adhesives, and / or other adhesives) layers to which layers 2.1-38 are attached to layers 2.1-34, and may have a thickness of 100 micrometers, 20 to 500 micrometers, at least 30 micrometers, less than 250 micrometers, less than 300 micrometers, or other suitable thicknesses.

[0943] If desired, additional polymer layers, such as polymer layers 2.1-32, may be attached to the outer surfaces 1.3-44 of the upper surface of layers 2.1-34. Layers 2.1-32 may be formed of elastomeric polymers or other soft polymer materials. Examples of materials that can be used to form polymer layers 2.1-32 include polyvinyl butyral and ethylene vinyl acetate. If desired, other polymers may be used to form layers 2.1-32. Layer 2.1-32 may be the outermost material layer of layers 2.1-14 (e.g., the outer surface of layer 2.1-32 may be exposed to regions 2.1-18), or layer 2.1-32 may be covered with a harder outer layer.

[0944] like Figure 2.1-3 As shown, for example, thin hard layers such as outer layer 2.1-30 can be attached to layer 2.1-34 using layers 2.1-32 (sometimes referred to as elastomeric polymer layers or polymer interlayers). The thickness of layer 2.1-32 can be 50 micrometers, 25 to 100 micrometers, at least 20 micrometers, at least 40 micrometers, at least 50 micrometers, less than 400 micrometers, 25 to 400 micrometers, less than 300 micrometers, less than 200 micrometers, 20 to 200 micrometers, 50 to 400 micrometers, or other suitable thicknesses. Layer 2.1-30 is formed of glass (including glass-ceramics), crystalline materials such as sapphire, or hard polymers (e.g., hardened acrylic). The thickness of layer 2.1-30 is preferably less than the thickness of layer 2.1-34 to help minimize the weight of layer 2.1-14.

[0945] In an exemplary arrangement, layers 2.1-30 are formed as separate layers of layer 2.1-34 attached to layer 2.1-34 by laminating layers 2.1-30 and 2.1-34 together using polymer layers 2.1-32 (e.g., a glass layer separate from layer 2.1-34). In this type of arrangement, the thickness of layer 2.1-30 can be at least 50 micrometers, at least 75 micrometers, at least 100 micrometers, less than 300 micrometers, less than 250 micrometers, less than 200 micrometers, less than 150 micrometers, less than 100 micrometers, 50 to 200 micrometers, 25 to 300 micrometers, 50 to 150 micrometers, or other suitable thicknesses (e.g., a thickness that provides sufficient hardness to the outermost surface of layer 2.1-14 to resist scratching). In addition to resisting scratching, including a hard outer layer such as layer 2.1-30 to layer 2.1-14 can also help enhance the strength of layer 2.1-14, thereby allowing for a reduction in the thickness of layer 34. To help match the curvature of layers 2.1-30 and 2.1-34 in this type of arrangement, molding operations (e.g., glass molding), machining and / or polishing operations, etching (wet and / or dry chemical etching) and / or other suitable forming operations can be used to shape layers 2.1-30 and 2.1-34 into the desired shape.

[0946] In some embodiments, layers 2.1-30 may be deposited as a coating on layers 2.1-32. As an example, deposition techniques such as physical vapor deposition and sol-gel deposition can be used to deposit an inorganic dielectric layer of a hard material (e.g., a glass coating formed from silicon nitride, silicon oxynitride, zirconium oxide, alumina, and / or other hard dielectric coatings deposited by physical vapor deposition, or a glass coating formed from an inorganic dielectric material based on silicon oxide deposited by sol-gel deposition). The thickness of this coating may be sufficient to allow for enhanced durability (e.g., to help prevent scratches in layers 2.1-32). As an example, layers 2.1-30 may have a thickness of at least 20 micrometers, at least 25 micrometers, at least 35 micrometers, and / or other suitable thicknesses. If desired, a liquid polymer (e.g., liquid acrylic acid) may be deposited and cured to form an acrylic-based hard coating (e.g., layers 2.1-30 may be a polymer hard coating that is harder than layers 2.1-32 and thus helps resist scratches).

[0947] 2.2: Systems with displays and sensors

[0948] Figure 2.2-1 This is a side view of an illustrative head-mounted electronic device. (Example:) Figure 2.2-1 As shown, 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 separating internal regions of the device 2.2-10, such as internal region 2.2-42, from external regions surrounding the device 2.2-10, such as 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, etc.) may be mounted on printed circuitry and / or other structures within the device 2.2-10 (e.g., in internal region 2.2-42).

[0949] To present an image to a user for viewing from an eye-friendly area, such as eye-friendly area 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 may be mounted in an optical module, such as optical module 2.2-36 (e.g., a lens barrel), to form a corresponding left and right optical system. For example, there may be a left rear display for presenting an image to the user's left eye via the left lens in the left eye-friendly area and a right rear display for presenting an image to the user's right eye in the right eye-friendly area. When structure 2.2-26 rests against the outer surface of the user's face (face surface 2.2-30), the user's eyes are located in eye-friendly area 34 at the rear R of device 2.2-10.

[0950] Support structure 2.2-26 may include a main support structure, such as a main housing portion 2.2-26M (sometimes referred to as the main portion). The main housing portion 2.2-26M may extend from the front side F of device 2.2-10 to the opposite rear side R of device 2.2-10. On the rear side R, the main housing portion 2.2-26M may have a padded structure to enhance user comfort when portion 2.2-26M rests against the face surface 2.2-30. If desired, support structure 2.2-26 may include optional head straps such as strap 2.2-26B, and / or other structures that allow device 2.2-10 to be worn on the user's head.

[0951] Device 2.2-10 may have a publicly viewable front display, such as display 2.2-14F mounted on the front side F of the main housing portion 2.2-26M. Display 2.2-14F may be viewable by the user when the user is not wearing device 2.2-10, and / or may be viewable by others near device 2.2-10. As an example, display 2.2-14F may be visible on the front side F of device 2.2-10 to an external viewer such as viewer 2.2-50 who is viewing device 2.2-10 in direction 2.2-52.

[0952] Figure 2.2-2 The diagram illustrates an exemplary system that may include a head-mounted device. Figure 2.2-2 As shown, system 2.2-8 may have one or more electronic devices 2.2-10. Device 2.2-10 may include a head-mounted device (e.g., Figure 2.2-1 Devices 2.2-10), accessories such as controllers and headsets, computing devices (e.g., cellular phones, tablet computers, laptop computers, desktop computers and / or telecomputing devices that supply content to head-mounted devices) and / or other devices that communicate with each other.

[0953] Each electronic device 2.2-10 may have control circuitry 2.2-12. Control circuitry 2.2-12 may include storage and processing circuitry for controlling the operation of device 2.2-10. Circuitry 2.2-12 may include storage devices such as hard disk drive storage devices, non-volatile memory (e.g., electrically programmable read-only memory configured to form a solid-state drive), volatile memory (e.g., static or dynamic random access memory), etc. The processing circuitry in control circuitry 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 (ASICs), and other integrated circuits. Software code may be stored on the storage devices in circuitry 2.2-12 and run on the processing circuitry in circuitry 2.2-12 to implement control operations for device 2.2-10 (e.g., data acquisition operations, operations involving adjusting components of device 2.2-10 using control signals, etc.). Control circuitry 2.2-12 may include wired and wireless communication circuitry. For example, control circuitry 2.2-12 may include radio frequency transceiver circuitry, such as cellular telephone transceiver circuitry, wireless local area network transceiver circuitry (e.g., Circuits), millimeter-wave transceiver circuits and / or other wireless communication circuits.

[0954] During operation, the communication circuitry of the devices in System 2.2-8 (e.g., the communication circuitry of the control circuitry of Device 2.2-10, or 2.2-12) can be used to support communication between electronic devices. For example, one electronic device can transmit video data, audio data, control signals, and / or other data to another electronic device in System 2.2-8. The electronic devices in System 2.2-8 can use wired and / or wireless communication circuitry to communicate over one or more communication networks (e.g., the Internet, a local area network, etc.). The communication circuitry can be used to allow Device 2.2-10 to receive data from and / or provide data to external equipment (e.g., a network-shared computer, portable devices such as handheld devices or laptops, online computing equipment such as a remote server or other remote computing equipment, or other electrical equipment).

[0955] 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 allow a user to provide user input to the device 2.2-10. The input-output device 2.2-22 can also be used to acquire information about the environment in which the device 2.2-10 is operating. Output components in device 2.2-22 can allow the device 2.2-10 to provide output to the user and can be used to communicate with external electrical equipment.

[0956] like Figure 2.2-2As shown, 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... Figure 2.2-1 The display 2.2-14R. Device 2.2-10 may include, for example: left and right components such as left and right scanning mirror display devices or other image projectors, silicon-based liquid crystal display devices, digital mirror devices or other reflective display devices; a left and right display panel based on a light-emitting diode pixel array (e.g., an organic light-emitting display having a polymer or semiconductor substrate or a display device based on a pixel array formed from a crystalline semiconductor light-emitting diode die); a liquid crystal display panel; and / or other left and right display devices that provide images to the left and right eye-adaptive regions, respectively, for viewing by the user's left and right eyes. Display components such as these components (e.g., an organic light-emitting display having a flexible polymer substrate or a display based on a pixel array formed from a crystalline semiconductor light-emitting diode die on a flexible substrate) can also be used to form the front-facing display of device 2.2-10, such as... Figure 2.2-1 The front-facing display 2.2-14F (sometimes referred to as a front-facing display, front monitor, or public-viewable display).

[0957] During operation, displays 2.2-14 (e.g., displays 2.2-14R and / or 2.2-14F) can be used to display visual content (e.g., still and / or moving images, text, graphics, movies, games, and / or other visual content, including pictures from camera sensors and pass-through video) to the user of device 2.2-10. 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 circuitry 2.2-12. This virtual content may sometimes be referred to as computer-generated content. Computer-generated content may be displayed in the absence of real-world content, or may be combined with real-world content. In some configurations, real-world images may be captured by a camera (e.g., a forward-facing camera, sometimes referred to as a front-facing camera), and computer-generated content may be electronically overlaid on portions of the real-world image (e.g., when device 2.2-10 is a virtual reality headset).

[0958] Input-output circuitry 2.2-22 may include sensors 2.2-16. Sensors 2.2-16 may include, for example, three-dimensional sensors (e.g., three-dimensional image sensors, such as structured light sensors that emit light beams and use two-dimensional digital image sensors to acquire image data for three-dimensional images from points or other light spots generated when these beams illuminate a target, binocular three-dimensional image sensors that use two or more cameras in a binocular imaging arrangement to acquire three-dimensional images, three-dimensional LIDAR (light detection and ranging) sensors (sometimes referred to as time-of-flight cameras or three-dimensional time-of-flight cameras), three-dimensional radio frequency sensors, or other sensors that acquire three-dimensional image data), cameras (e.g., two-dimensional infrared and / or visible digital image sensors), gaze tracking sensors (e.g., gaze tracking systems based on image sensors and, if necessary, also based on light sources emitting one or more light beams, which, after reflection from the user's eyes, are used to acquire image data for three-dimensional images), cameras (e.g., two-dimensional infrared and / or visible digital image sensors), and gaze tracking sensors (e.g., gaze tracking systems based on image sensors and, if necessary, ...). Sensors such as those used for tracking, 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, flashing sensors that acquire time information about the presence of ambient light conditions such as time-varying ambient light intensity associated with artificial lighting, microphones for acquiring voice commands and other audio inputs, sensors configured to acquire information about motion, positioning and / or orientation (e.g., accelerometers, gyroscopes, compasses and / or inertial measurement units including all of these sensors or a subset of one or two of these sensors), and / or other sensors.

[0959] Sensors and other input devices in input-output devices 2.2-22 can be used to acquire user input and other information. If desired, input-output devices 2.2-22 may include other devices 2.2-24, such as haptic output devices (e.g., vibrating components), light-emitting diodes, lasers and other light sources (e.g., light-emitting devices that emit light to illuminate the environment around devices 2.2-10 when ambient light levels are low), speakers such as earphones for generating audio output, circuitry for receiving wireless power, circuitry for wirelessly transmitting power to other devices, batteries and other energy storage devices (e.g., capacitors), joysticks, buttons and / or other components.

[0960] Such as combination Figure 2.2-1The electronic device 2.2-10 may have a head-mounted support structure such as a head-mounted support structure 2.2-26 (e.g., a head-mounted housing structure such as a housing wall, strap, etc.). The head-mounted support structure may be configured to be worn on the user's head during operation of the device 2.2-10 (e.g., against the user's face, thereby covering the user's eyes), and may support the display 2.2-14, sensors 2.2-16, other components 2.2-24, other input-output devices 2.2-22, and control circuitry 2.2-12 (see, for example...). Figure 2.2-1 Components 2.2-40 and optical modules 2.2-36).

[0961] Figure 2.2-3 This is a front view of device 2.2-10 in an exemplary configuration, where device 2.2-10 has a common viewable display such as a front-facing display 2.2-14F. Figure 2.2-3 As shown, the support structure 2.2-26M of device 2.2-10 may have a right portion and a left portion such as portions 2.2-26R and 2.2-26L, which are coupled via an inserted nose bridge portion such as portion 2.2-26NB. Portion 2.2-26NB may have a curved external surface such as nose bridge surface 2.2-90, which is configured to receive and rest on the user's nose to help support the main housing portion 2.2-26M on the user's head.

[0962] The display 2.2-14F may have a valid area, such as a valid area AA, configured to display an image and an invalid area IA, not displaying an image. The valid area AA may be rectangular, a rectangle with rounded corners, may have teardrop-shaped portions on the left and right sides of the device 2.2-10, may have a shape with straight edges, a shape with curved edges, a shape with peripheral edges having both straight and curved portions, and / or other suitable shapes. Figure 2.2-3 As shown, the effective area AA may have a curved recess at the bridge portion 2.2-26NB of the main housing portion 2.2-26. The presence of the nose-shaped recess in the effective area AA helps to fit the effective area AA within the available space of the housing portion 2.2-26M without unduly restricting the size of the effective area AA.

[0963] The effective area AA contains a pixel array. Pixels can be, for example, light-emitting diode pixels formed on a flexible display panel substrate using thin-film organic light-emitting diodes or crystalline semiconductor light-emitting diode dies (sometimes referred to as micro-light-emitting diodes). If desired, configurations in which displays 2.2-14F utilize other display technologies may also be used. In this document, exemplary arrangements in which displays 2.2-14 are formed of light-emitting diode displays, such as organic light-emitting diode displays formed on a flexible substrate (e.g., a substrate formed of a bendable polyimide layer or other flexible polymer sheet), are sometimes described as examples. The pixels of the effective area AA can be in display devices such as… Figure 2.2-3 The display panel 2.2-14P (e.g., a flexible organic light-emitting diode display panel) is formed on it. In some configurations, the shape of the panel 2.2-14P may have a peripheral edge comprising straight segments or a combination of straight and curved segments. A configuration in which the entire shape of the panel 2.2-14P is characterized by curved peripheral edges may also be used.

[0964] The display 2.2-14F may have invalid areas, such as invalid area IA, that do not contain pixels and do not display images. Invalid area IA may form an invalid boundary area extending along one or more portions of the peripheral edge of valid area AA. Figure 2.2-3 In the exemplary configuration, the invalid region IA has an annular shape surrounding the valid region AA. In this type of arrangement, the width of the invalid region IA can be relatively constant, and the inner and outer edges of the region IA can be characterized by straight and / or curved segments, or can be curved along the entire length of the edge. For example, the outer edge of the region IA (e.g., the periphery of the display 2.2-14F) can have a curved profile extending parallel to the curved edge of the valid region AA.

[0965] In some configurations, device 2.2-10 may 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 intensity of a magnetic field. Device 2.2-10 may have one or more electromagnets configured to emit a magnetic field. The magnetic field may be measured by wireless accessories near device 2.2-10, allowing the accessories to determine their orientation and location relative to device 2.2-10. This allows the accessories to wirelessly provide device 2.2-10 with real-time information about their current location, orientation, and movement, enabling the accessories to act as wireless controllers. Accessories may include wearable devices, handheld devices, and other input devices.

[0966] In an exemplary configuration, device 2.2-10 may have a coil, such as exemplary coil 2.2-54, extending around the periphery of display 2.2-14F (e.g., below the inactive area IA or other portion of display 2.2-14F). Coil 2.2-54 may have any suitable number of turns (e.g., 1-10, at least 2, at least 5, at least 10, 10-50, less than 100, less than 25, less than 6, etc.). These turns may be formed on a substrate by metal traces, by wires, and / or by other conductive lines. During operation, control circuitry 2.2-12 may supply an alternating current (AC) drive signal to coil 2.2-54. The drive signal may have a frequency of 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 (as an example). When AC current flows through coil 2.2-54, a corresponding magnetic field is generated near device 2.2-10. Electronic devices located near device 2.2-10, such as wireless controllers with magnetic sensors, can use the magnetic field as a reference, allowing the wireless controllers to determine their orientation, positioning, and / or movement relative to device 2.2-10 to provide input to device 2.2-10.

[0967] As an example, consider a handheld wireless controller used to control the operation of device 2.2-10. During operation, device 2.2-10 uses coil 2.2-54 to emit a magnetic field. When the handheld wireless controller is moved, the controller's magnetic sensor can monitor the controller's position and movement relative to device 2.2-10 by monitoring the strength, orientation, and changes in strength and / or orientation of the magnetic field emitted by coil 2.2-54 as the user moves the controller in the air. The electronic device can then wirelessly transmit information about the controller's position and orientation to device 2.2-10. In this way, the user can manipulate the handheld controller, wearable controller, or other external accessories to provide air gestures, pointing inputs, manipulation inputs, and / or other user inputs to device 2.2-10.

[0968] Device 2.2-10 may have optical components (e.g., Figure 2.2-2The components of the optical sensor in sensor 2.2-16 are included. These components can be mounted in any suitable location on the head-mounted 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 can face rearward (e.g., when mounted on the back of device 2.2-10), face sideways (e.g., left or right), face downward or upward, face the front of device 2.2-10 (e.g., when mounted on the front of device 2.2-10), can be mounted to any combination of these directions (e.g., forward, right, and downward) and / or can be mounted in other suitable orientations. In an exemplary configuration, at least some of the components of device 2.2-10 are mounted outward and forward (and optionally facing sideways and / or upward and downward). For example, the forward-facing cameras for pass-through video can be configured to be mounted on the left and right sides of the front of the device 2.2-10, in which the cameras are slightly diverged along the horizontal dimension, such that the fields of view of these cameras overlap to some extent when capturing a wide-angle image of the environment in front of the device 2.2-10. If desired, the captured image may include portions of the user's surrounding environment below, above, and to the sides of the area directly in front of the device 2.2-10.

[0969] To help conceal components such as optical elements from being seen from the outside of the device 2.2-10, it may be desirable to utilize an aesthetically pleasing overlay structure to cover some or all of these components. The overlay structure may include transparent portions (e.g., windows for optical elements) characterized by sufficient optical transparency to allow the overlapping optical elements to operate satisfactorily. For example, an ambient light sensor may be covered with a layer that appears opaque to an external viewer to help conceal the sensor from view, but allows sufficient ambient light to pass through to enable satisfactory ambient light measurements. As another example, optical elements emitting infrared light may be overlapped with a visually opaque material that is transparent to infrared light.

[0970] In the exemplary configuration, the optical components of device 2.2-10 can be mounted on... Figure 2.2-3In the invalid region IA, the aesthetic overlay structure can be formed as an annular shape overlapping the optical components in the invalid region IA. The aesthetic overlay structure can be formed from ink, polymer structures, structures including metals, other materials, and / or combinations of these materials. In an exemplary configuration, the aesthetic overlay structure can be formed from an annular member having a footprint matching the footprint of the invalid region IA. For example, if the valid region AA comprises a left and right portion having a teardrop shape, the annular member can have a curved edge following the curved periphery of the teardrop-shaped portion of the valid region AA. The annular member can be formed from one or more polymer structures (e.g., the annular member can be formed from a polymer ring). Because the annular member helps to conceal the overlapping components so that they are not visible, the annular member is sometimes referred to as a shield or annular shield member. The appearance of the shield or other aesthetic overlay structure can be characterized by neutral colors (white, black, or gray) or non-neutral colors (e.g., blue, red, green, gold, rose gold, etc.).

[0971] If required, the display 2.2-14F may have a protective display overlay. The overlay may overlap with the active area AA and the inactive area IA (e.g., in the area from...). Figure 2.2-1 When viewing in the direction 2.2-52, the entire front surface of the device 2.2-10 may be covered by a cover layer. The cover layer, sometimes referred to as the shell wall or transparent shell wall, may have a rectangular shape, a shape with teardrop portions, an elliptical shape, or other shapes with curved and / or straight edges.

[0972] The cover layer may be formed of transparent materials such as glass, polymers, transparent crystalline materials such as sapphire, light-transmitting ceramics, other transparent materials, and / or combinations of these materials. As an example, the protective display cover layer of display 2.2-14F may be formed of safety glass (e.g., laminated glass comprising a light-transmitting glass layer and a laminated polymer film). Optional coatings may be applied to the surface of the display cover layer. If desired, the display cover layer may be chemically strengthened (e.g., using an ion-exchange process to produce a scratch-resistant outer material layer under compressive stress). In some configurations, the display cover layer may be formed of a stack of two or more material layers (e.g., a first structural glass layer and a second structural glass layer, a rigid polymer layer coupled to a glass layer or another rigid polymer layer, etc.) to enhance the performance of the cover layer.

[0973] In the effective area AA, the display overlay may overlap with the pixels of the display panel 2.2-14P. The display overlay in the effective area AA is preferably transparent to allow viewing of the image presented on the display panel 2.2-14P. In the ineffective area IA, the display overlay may overlap with a ring-shaped shield or other aesthetically pleasing covering structure. The shield and / or other covering structure (e.g., an opaque ink coating on the inner surface of the display overlay and / or structure) may be sufficiently opaque to help conceal some or all of the optical components in the ineffective area IA from being seen. Windows may be provided in the shield or other aesthetically pleasing covering structure to help ensure satisfactory operation of the optical components overlapped by these structures. Windows may be formed by apertures, by areas of the shield or other aesthetically pleasing covering structure that have been locally thinned to enhance light transmittance, by window members with desired light transmittance properties already inserted into mating openings in the shield, and / or by other shield window structures.

[0974] exist Figure 2.2-3 In the example, device 2.2-10 includes optical components, such as 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 (as examples). These optical components (e.g., from...) Figure 2.2-2 Each optical component in the selected optical sensors, light-emitting devices, etc. (as per sensor 2.2-16) can be configured to detect light and, if necessary, to emit light (e.g., ultraviolet, visible, and / or infrared light).

[0975] In an exemplary configuration, optical component 2.2-60 can sense ambient light (e.g., visible ambient light). Specifically, optical component 2.2-60 may have a photodetector that senses changes in ambient light intensity over time. As an example, if a 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., 60 Hz AC mains). The photodetector of component 2.2-60 can sense the artificial light from the artificial light source, characterized by intensity fluctuations at 60 Hz. Control circuitry 2.2-12 can use this information to adjust clocks or other timing signals associated with the operation of the image sensor in device 2.2-10 to help avoid unwanted interference between the light source frequency and the frame rate or other frequencies associated with image capture operation. Control circuitry 2.2-12 can also use measurements from component 2.2-60 to help identify the presence and type of artificial light. In this way, control circuitry 2.2-12 can detect the presence of light, such as fluorescence or other light with known non-ideal color characteristics, and can compensate for color shifts (e.g., white point adjustment) in color-sensitive components such as cameras and displays. Because optical component 2.2-60 measures fluctuations in light intensity, component 2.2-60 is sometimes referred to as a flicker sensor or ambient light frequency sensor.

[0976] 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 monochromatic sensor that measures the intensity of ambient light. In a multi-photodetector configuration, each photodetector may consist of overlapping optical filters that allow different wavelength bands (e.g., different visible and / or infrared passbands) to pass through. The optical filter passbands may overlap at their edges. This allows component 2.2-62 to act 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 operation of device 2.2-10, control circuitry 2.2-12 may take action based on the measured ambient light intensity and color. As an example, the white point of a display or image sensor may be adjusted based on the measured ambient light color, or other display or image sensor color adjustments may be performed. The intensity of the display may be adjusted based on light intensity. For example, the brightness of display 2.2-14F may be increased under bright ambient light conditions to enhance the visibility of the image on the display, and the brightness of display 2.2-14F may be decreased under dim lighting conditions to save power. Image sensor operation and / or light source operation can also be adjusted based on ambient light readings.

[0977] The optical components in the effective 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 movement of device 2.2-10. Components 2.2-80 and 2.2-64 may be visible light cameras (and / or cameras sensitive to visible and infrared wavelengths) and may be combined with an inertial measurement unit to form a visual inertial ranging (VIO) system.

[0978] 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. These cameras (sometimes referred to as scene cameras or pass-through video cameras) capture moving images when the user's eye is positioned within the eye-fitting zone 2.2-34 at the rear of device 2.2-10, and these moving images are displayed in real-time on display 2.2-14R for the user's viewing. By displaying pass-through images (pass-through video) to the user in this manner, real-time information about the user's surrounding environment is provided. If desired, virtual content (e.g., computer-generated images) may be overlaid on a portion of the pass-through video. Device 2.2-10 can also operate in a non-pass-through video mode, in which components 2.2-78 and 2.2-66 are turned off, and only movie content, game content, and / or other virtual content that does not contain real-time real-world images are provided to the user.

[0979] The input-output device 2.2-22 of device 2.2-10 can acquire user input for controlling the operation of device 2.2-10. As an example, the microphone in device 2.2-10 can acquire voice commands. Buttons, touch sensors, force sensors, and other input devices can acquire user input from the user's fingers or other external objects touching device 2.2-10. In some configurations, it may be desirable to monitor the user's hand gestures or other body part movements. This allows the user's hand position or other body part position to be replicated in games or other virtual environments, and allows the user's hand movements to act as hand gestures (air gestures) for controlling the operation of device 2.2-10. Cameras operating in visible and infrared wavelengths, such as tracking cameras (e.g., optical components 2.2-76 and 2.2-68), can be used to capture user input such as hand gesture input. Tracking cameras such as these can also track references and other identifiable features on these controllers and other external accessories (attached device 2.2-10 of system 2.2-8) during the use of controllers to control the operation of device 2.2-10. If needed, a tracking camera can help determine the position and orientation of a handheld or wearable controller, which senses its position and orientation by measuring the magnetic field generated by coil 2.2-54. Therefore, the use of a tracking camera can help track hand movements and controller movements used to move pointers and other virtual objects displayed to the user, and can otherwise assist in the operation of device 2.2-10.

[0980] The tracking camera can operate satisfactorily in the presence of sufficient ambient light (e.g., bright visible ambient light conditions). In dim environments, supplementary light sources such as supplementary infrared light sources (e.g., optics 2.2-82 and 2.2-84) can provide supplementary illumination. Each infrared light source may include one or more light-emitting devices (light-emitting diodes or lasers) and may be configured to provide a fixed and / or controllable infrared beam that serves as supplementary illumination for the tracking camera. The infrared light sources can be turned off under bright ambient light conditions if needed and can be turned on in response to the detection of dim ambient light (e.g., using the ambient light sensing capability of optics 2.2-62).

[0981] The three-dimensional sensors in device 2.2-10 can be used to perform biometric identification operations (e.g., facial identification for authentication), to determine the three-dimensional shape of objects in a user's environment (e.g., mapping the user's environment so that a matching virtual environment can be created for the user), and / or to otherwise acquire three-dimensional content during operation of device 2.2-10. As an example, optics 2.2-74 and 2.2-70 can be three-dimensional structured light image sensors. Each three-dimensional structured light image sensor may have one or more light sources that provide structured light (e.g., a dot projector that projects an infrared dot array onto the environment, a structured light source that generates a line grid, or other structured light components that emit structured light). Each three-dimensional structured light image sensor may also include a flood illuminator (e.g., a light-emitting diode or laser that emits a wide infrared beam). Using flood illumination and structured light illumination, optics 2.2-74 and 2.2-70 can capture facial images, images of objects in the environment surrounding device 2.2-10, etc.

[0982] Optical component 2.2-72 can be an infrared three-dimensional time-of-flight camera that uses time-of-flight measurements of the emitted light to acquire three-dimensional images of objects in the environment surrounding device 2.2-10. Component 2.2-72 can have a longer range and a narrower field of view compared to the three-dimensional structured light cameras of optical components 2.2-74 and 2.2-70. The operating range of component 2.2-72 can be 30cm to 7m, 60cm to 6m, 70cm to 5m, or other suitable operating ranges (as an example).

[0983] Figure 2.2-4 This is a top view of device 2.2-10 in an illustrative arrangement, wherein the display 2.2-14F and the main housing portion 2.2-26M have been configured to be curved around a curved surface (curved face surface 2.2-30) surrounding the user's face. Specifically, the rear surface 2.2-96 of the housing portion 2.2-26M on the rear side R of device 2.2-10 may have a curve around axis 2.2-98 (e.g., in...). Figure 2.2-4 The example shows a curved shape (parallel to the vertical Z-axis). Comfort is enhanced when wearing the device (2.2-10) by smoothly wrapping the outer shell portion 2.2-26M around the curved surface of the user's head.

[0984] like Figure 2.2-4As shown, the display 2.2-14F and other structures on the front of the device 2.2-10 may have protective coverings, such as display cover 2.2-92 (e.g., the front portion of the housing portion 2.2-26M, which may sometimes be referred to as a front housing wall, a transparent dielectric housing wall, or a dielectric housing member). In some embodiments, the display cover 2.2-92 may include an area characterized by a curved surface that can be flattened into a plane without distortion (sometimes referred to as a developable surface or a curved surface without composite curvature). The display cover 2.2-92 may also include an area characterized by composite curvature (e.g., a surface that can only be flattened into a plane with deformation, sometimes referred to as a non-developable surface).

[0985] In the effective area AA of display 2.2-14F, overlay layer 2.2-92 overlaps with the pixel P array in display panel 2.2-14P. In the ineffective area IA, overlay layer 2.2-92 does not overlap with any pixels, but may overlap with optical components such as... Figure 2.2-3 The optical components are shown overlapping. To help reduce the size and weight of the device 2.2-10, the display 2.2-14F may have a curved shape that wraps around the front of the user's head, parallel to the face surface 2.2-30 and parallel to the housing portion 2.2-26M. For example, the display panel 2.2-14P may have a shape that allows the panel 2.2-14P to bend around the bending axis 2.2-94 (e.g., Figure 2.2-4 A flexible substrate bent (parallel to the Z-axis bending axis in the example). In the effective area AA of the display 2.2-14F, the display cover layer 2.2-92 may have an inner surface and a corresponding curved outer surface, the inner surface having a curved cross-sectional profile conforming to the bending of the display panel 2.2-14P. In the ineffective area IA, the display cover layer 2.2-92 may also be curved (e.g., with a tighter bending radius and greater curvature compared to the effective area AA). If desired, a polymer layer (sometimes referred to as a shield or polymer component) may be inserted between the display cover layer 2.2-92 and the display panel 2.2-14P. The polymer layer can be separated from the pixels of the panel 2.2-14P by an air gap, and can also be separated from the inner surface of the display cover layer 2.2-92 by an air gap (as an example).

[0986] Figure 2.2-5A This is a cross-sectional side view of the monitor 2.2-14F viewed in the X direction. (As shown) Figure 2.2-5AAs shown, in the exemplary configuration, the cross-sectional profile of the display panel 2.2-14P (in a plane parallel to the YZ plane) can be straight rather than curved. This helps prevent wrinkling or other distortions in the flexible substrate material of the display panel 2.2-14P when it is bent around the bending axis 2.2-94 to wrap around the curved surface of the user's face. In this example, the 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). Figure 2.2-5A Panel 2.2-14P can be attached (e.g., using an adhesive) to the inner surface of layer 2.2-92. In this scenario, the inner surface of layer 2.2-92 can be a developable surface that pairs with the outward developable surface of panel 2.2-14P. The corresponding outer surface of layer 2.2-92 in the active region AA can be a developable surface or a surface with a composite curvature. In the inactive region IA, layer 2.2-92 can include an inner surface and / or an outer surface with a composite curvature, and / or the inner surface and / or the outer surface can be developable surfaces. If desired, the entire outer surface of layer 2.2-92 can have a composite curvature (in both the active region AA and the inactive region IA), the inner surface of layer 2.2-92 in the active region AA can be a developable surface to which panel 2.2-14P is laminated using an adhesive, and the inner surface of layer 2.2-92 in the inactive region IA can have a composite curvature and / or can be a developable surface.

[0987] Figure 2.2-5B Another exemplary configuration of the display 2.2-14F is shown in the figure. For example... Figure 2.2-5BAs shown in the cross-sectional side view, if desired, the display cover layer 2.2-92 may have a cross-sectional profile with full curvature across layer 2.2-92. In this type of arrangement, the surface of the ineffective region IA of the display cover layer 2.2-92 may have a composite curvature, and the effective region AA of the display cover layer 2.2-92 may also have a composite curvature (e.g., layer 2.2-92 may not contain any region with a developable surface). A polymer layer such as polymer layer 2.2-130 (which may sometimes be referred to as a shield or shield cover) may be inserted 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 (e.g., the display panel 2.2-14P may be bent about axis 2.2-94). In the effective region AA where polymer layer 2.2-130 overlaps with the pixels of panel 2.2-14P, polymer layer 2.2-130 can also be bent around axis 2.2-94 (e.g., the inner and outer surfaces of polymer layer 2.2-130 in the effective region AA can be developable surfaces). In the ineffective region IA, the inner and outer surfaces of polymer layer 2.2-130 can have a composite curvature. An air gap can separate panel 2.2-14P from the inner surface of layer 2.2-130 and can separate the outer surface of layer 2.2-130 from the inner surface of layer 2.2-92.

[0988] Other arrangements of layer 2.2-130 may be used if desired. For example, the side of layer 2.2-130 facing the display panel 2.2-14P may have a developable surface in the effective area AA, while the side of layer 2.2-130 facing layer 2.2-92 may have a composite curvature in the effective area AA (e.g., layer 2.2-130 may have a non-uniform thickness). Layer 2.2-92 may also have different configurations. 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 effective area AA and / or area IA may be a developable surface. Other arrangements in which layer 2.2-92 and / or layer 2.2-130 have variable thicknesses may also be used. In the ineffective area IA, multiple polymer structures may be joined. For example, in area IA, an annular polymer member (sometimes referred to as a shroud decoration) may be joined to layer 2.2-130, which may form a shroud cover member extending across the entire front of device 2.2-10. If desired, the protective cover and the protective cover may sometimes be referred to individually or collectively as forming a protective cover, protective cover component, etc. Coloring (e.g., dyes, pigments, and / or other colorants) may be included in layers 2.2-130. For example, layer 2.2-130 may be colored to exhibit 30%-80% visible light transmittance to help conceal internal structures in device 2.2-10, such as display panel 2.2-14P, from being seen when not in use.

[0989] Figure 2.2-6 This is a front view of a portion of the display 2.2-14F and the display overlay 2.2-92. The inner and outer surfaces of the display overlay 2.2-92 that directly overlap with the effective area AA and the display panel 2.2-14P can be developable surfaces and / or may include areas with compound curvature. In an illustrative configuration, as described in conjunction with Figures 4 and 5A, the inner surface of the overlay 2.2-92 in area AA may be bent about a bending axis 2.2-94 without exhibiting curvature about any axis orthogonal to axis 2.2-94. The outer surface of the overlay 2.2-92 in area AA can be a developable surface or a surface with compound curvature. Developable surfaces are used for the inward-facing sides of the display overlay 2.2-92 (and, if desired, for...). Figure 2.2-5B The optional inner side of layer 2.2-130 helps ensure that the display panel 2.2-14P does not wrinkle or otherwise become damaged during the bending of the display panel 2.2-14P to form a shape that conforms to the user's head.

[0990] The display panel 2.2-14P may have an outward-facing surface in the effective area AA, which is a deployable surface. This display panel surface may be attached to the corresponding inner deployable surface of layer 2.2-130 or the corresponding inner deployable surface of layer 2.2-92, or may be spaced apart from the inner surfaces of layer 2.2-130 and / or layer 2.2-92 by an air gap (as an example).

[0991] If desired, some or all of the inner and outer surfaces of the display overlay layer 2.2-92 in the inactive region IA may be characterized by a composite curvature. This allows the periphery of the display 2.2-14F to smoothly transition away from the active region and provides the device 2.2-10 with an attractive appearance and compact shape. The composite curvature of the display overlay layer 2.2-92 in the inactive region IA also facilitates the placement of optical components below the inactive region IA in the desired orientation. If desired, all regions of layer 2.2-92 may have a composite curvature (e.g., the inner and outer surfaces of layer 2.2-92 may have a composite curvature in both region IA and region AA).

[0992] exist Figure 2.2-6 In the exemplary configuration, the display cover layer 2.2-92 has curved peripheral edges and the inward and outward surfaces of the display cover layer 2.2-92 have composite curvature in the ineffective region IA, and the display cover layer 2.2-92 along... Figure 2.2-6 The cross-sectional profile of each exemplary line in exemplification line 2.2-100 is curved (e.g., Figure 2.2-6In the example, the entire peripheral annular invalid region of the display 2.2-14F is partially covered by the display cover layer 2.2-92, which has an inner and outer surface with a 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 manufacturing techniques. Other arrangements may also be used (e.g., configurations in which the display cover layer 2.2-92 has at least some developable surfaces (inner and / or outer surfaces) in the invalid region IA). Figure 2.2-6 The arrangement is illustrative.

[0993] Figure 2.2-7 , Figure 2.2-8 and Figure 2.2-9 This is a front view of the exemplary upper left portion of the display overlay 2.2-92. Device 2.2-10 may have a symmetrical right-hand overlay portion. Figure 2.2-7 The example illustrates how the peripheral edges of the display overlay 2.2-92 can have straight edges (e.g., a roughly rectangular shape with straight edges) and rounded corners. Figure 2.2-8 In the example, the display overlay 2.2-92 has a teardrop shape on the upper left and upper right sides. Figure 2.2-9 The diagram illustrates how the upper corner of the display overlay 2.2-92 can have a swept curve (e.g., to help soften the visual appearance of the device 2.2-10 when viewed from the front).

[0994] Figures 10, 11, and 12 are front views of the illustrative lower left portion of the display overlay 2.2-92. Figure 2.2-10 As shown, the lower half of the cover layer 2.2-92 can be characterized by a rectangular shape with rounded corners. Figure 2.2-10 The cover layer 2.2-92 can have Figure 2.2-7 The upper portion of the shape shown is an example. In the bridge portion of device 2.2-10, the cover layer 2.2-92 may have a recessed, curved bridge edge shape (see, for example, curved edge surface 2.2-90). Figure 2.2-11 In the exemplary arrangement, the display overlay 2.2-92 has teardrop-shaped lower left and lower right sides (e.g., can be used with...). Figure 2.2-8 The top left and top right teardrop shapes shown are used together as display overlays. Figure 2.2-12 This illustrates how the lower portion of the display overlay 2.2-92 can have a more gradually curved shape.

[0995] Generally, when viewed from the front of device 2.2-10, the upper and lower portions of cover layer 2.2-92 can have any suitable shape. The shape of cover layer 2.2-92 can be determined by factors such as aesthetics, size, ability to facilitate proper placement of optical components in the ineffective region IA, and ability to provide coverage of the desired effective region (overlapping over the effective region AA). Any of the exemplary shapes of the upper portion of device 2.2-10 shown in Figures 7, 8, and / or 9 can be used in combination with any of the exemplary shapes of the lower portion of device 2.2-10 shown in Figures 10, 11, and 12. The overall shape of cover layer 2.2-92 can be symmetrical about the bridge of the nose (e.g., the left and right halves of layer 2.2-92 can exhibit mirror symmetry). The shapes in Figures 7, 8, 9, 10, 11, and 12 are exemplary. Other shapes may be used if desired.

[0996] Figure 2.2-13 This is an exploded cross-sectional top view of a portion of device 2.2-10, showing how the display overlay 2.2-92 may have portions overlapping with the display panel 2.2-14P and overlapping with aesthetic overlay structures such as a shield 2.2-130 (e.g., an annular shield portion sometimes referred to as a shield trim or shield trim member, which may optionally be attached in region IA to a shield cover covering the display 2.2-14F, such as an optional polymer layer 2.2-130). The aesthetic overlay structure in the inactive region IA may be formed by an opaque masking layer (e.g., a layer of black ink) and / or other coatings on the inner surface of the display overlay 2.2-92 and / or on the shield, by separate structures formed of metal, polymer, glass, or other materials, and / or other structures that may help conceal the overlapping component 2.2-104. Component 2.2-104 may include sensor 16 and... Figure 2.2-2 Other input-output devices 2.2-22. For example, component 2.2-104 can be an optical component, such as... Figure 2.2-3Components 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. In the inactive region IA, the cover layer 2.2-92 may have curved inner and outer surfaces (e.g., surfaces with composite curvature). The shield 2.2-102 (and, if desired, layer 2.2-130 in region IA) may optionally have corresponding inner and outer surfaces (e.g., surfaces with composite curvature). Component 2.2-104 can be operated through optical component windows in shield 2.2-102 (and optionally, in layer 2.2-130 in region IA) and corresponding areas in layer 2.2-92. These windows may be formed by recesses and / or through-hole openings in shields 2.2-102 (and optionally, in layers 2.2-130) and / or layers 2.2-92, by window members disposed within openings in shields 2.2-102 (and optionally, in layers 2.2-130) and / or layers 2.2-92, by portions of shields 2.2-102 (and optionally, in layers 2.2-130) and / or layers 2.2-92 exhibiting sufficient optical transparency to allow the overlapping components to operate satisfactorily, and / or by other structures in shields 2.2-102 (and optionally, in layers 2.2-130) and / or windows 2.2-92.

[0997] If desired, component 2.2-104 may include components of a camera (e.g., a visible and / or infrared image sensor, a time-of-flight sensor, a structured light 3D sensor, etc.) that are sensitive to optical distortions imposed 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 be partially operated via the cover layer 2.2-92 in the inactive region IA, characterized by an outer surface with a composite curvature and an inner surface with a composite curvature or a developable inner surface. In this type of case, the control circuitry of device 2.2-10 may be configured digitally to compensate for optical distortions introduced as light (e.g., real-world image light) passes through layer 2.2-92 to reach the camera or other optical sensor. As an example, for each optical component operating through layers 2.2-92 (e.g., portions of layer 2.2-92 in the invalid region IA including inner and / or outer surfaces with composite curvature), the amount of image distortion (e.g., stretching, shifting, trapezoidal distortion, barrel distortion, pincushion distortion, and / or other optical distortions) imposed by layer 2.2-92 can be measured and characterized. During operation of device 2.2-10, image data captured by the camera and / or other sensor data acquired by optical components overlapping layer 2.2-92 can be compensated accordingly (e.g., equal and opposite amounts of digital image distortion can be applied to the captured image data to remove known distortion effects of layer 2.2-92). In this way, high-quality (undistorted) images and / or other sensor data can be acquired by cameras and / or other optical components operating through the curved portions of layer 2.2-92. This allows for the provision of an attractive shape to layer 2.2-92 (e.g., a shape having one or more surfaces characterized by composite curvature).

[0998] When assembled into device 2.2-10, the display cover 2.2-92 and the shield 2.2-102 (and optionally, layer 2.2-130) can be mounted to exposed edge portions of a polymer housing structure, metal housing wall, or other housing structure within the main housing portion 2.2-26M. As an example, the main housing portion 2.2-26M may have polymer sidewall members extending around the periphery of the display cover 2.2-92 and supporting the peripheral edge of the display cover 2.2-92. The shield 2.2-102 may have an annular shape extending along the edge of the display cover 2.2-92 in the inactive region IA. In the exemplary configuration, adhesive is used to attach the display cover layer 2.2-92 to the shield 2.2-102 (and / or layer 2.2-130), and adhesive is used to attach the shield 2.2-102 (and / or layer 2.2-130) to the exposed front edge of the sidewall in the main housing portion 2.2-26M. Component 2.2-104 may be attached to the shield 2.2-102 (and / or layer 2.2-130) and / or may be supported on an internal housing structure (e.g., a bracket, frame member, etc.), aligned with the optical window in the shield 2.2-102 (and / or layer 2.2-130) and the corresponding portion of layer 2.2-92.

[0999] Figure 2.2-14 This is a cross-sectional side view of a portion of display 2.2-14F. Figure 2.2-14 In the example, display panel 2.2-14P is a three-dimensional display panel having an array of pixels P superimposed by biconvex lenses 2.2-106 (e.g., display panel 2.2-14P is for viewers such as...). Figure 2.2-1 (An automated stereoscopic display that generates glasses-free 3D images for viewers 2.2-50). As an example, lens 2.2-106 may be a semi-cylindrical lens element extending along the pixel column (e.g., Figure 2.2-14 (The example shows a lens element extending parallel to the Z dimension). Lenses 2.2-106 can be omitted if needed (e.g., the display panel 2.2-14P can have an array of pixels P that are not overlapped by lenses 2.2-106 to form a two-dimensional display).

[1000] Air gaps, such as gap 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. Optional layer 2.2-130 can... Figure 2.2-14A gap 2.2-114 is formed within the layer, such that layer 2.2-130 has an outer surface separated from layer 2.2-92 by a first air gap and an opposite inner surface separated from lens 2.2-106 and the pixels P of display panel 2.2-14P by a second air gap. In the arrangement in which lens 2.2-106 is present, the air gap 2.2-114 (and therefore there is no direct contact between the inner surface of layer 2.2-130 and lens 2.2-106) allows lens 2.2-106 to operate satisfactorily. In this document, the display cover layer 2.2-92 and optional layer 2.2-130 may sometimes be formed of transparent materials such as glass, polymers, transparent ceramics, crystalline materials such as sapphire, one or more sublayers of these materials, and / or other materials that have been laminated together (e.g., using adhesives, etc.). In this document, a configuration in which layer 2.2-92 is a glass layer and layer 2.2-130 is a polymer layer may sometimes be described as an example.

[1001] A coating may be provided on one or more of the layers in display overlay 2.2-92. For example... Figure 2.2-14 As illustrated in the exemplary configuration, the display overlay layer 2.2-92 may include, for example, layers such as layer 2.2-108 formed of one or more sublayers (e.g., glass layers and / or polymer layers), a polymer layer that helps provide safety glass functionality to layer 2.2-92 (see, for example, exemplary polymer film 112, which has been attached to the inner surface of glass layer 2.2-108 to form a laminated glass layer), and 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). Coating 2.2-110 may be, for example, an anti-reflective coating formed of one or more inorganic dielectric layers and / or other layers, the thickness and refractive index values ​​of which are selected to minimize visible light reflection from the outermost surface of layer 2.2-92 and help maintain the desired appearance (e.g., neutral tone) of layer 2.2-92. If desired, the display panel 2.2-14P can be a touch-sensitive display (e.g., a display consisting of capacitive touch sensor circuitry superimposed or combined with capacitive touch sensor circuitry). 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).

[1002] To help strengthen layers 2.2-92, layers 2.2-108 may be formed of chemically strengthened glass (e.g., glass layers treated in an ion exchange bath to bring the outer surface of the glass layer under compression relative to the interior of the glass layer). This helps layer 2.2-108 resist scratches and breakage. 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 together with a polymer layer), a stack of two polymer layers, three or more polymer layers and / or glass layers, etc. If desired, layer 2.2-108 may be formed from a stack of mixed 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 the structural polymer layer using heat and / or pressure, or a glass layer attached to the structural polymer layer using a polymer adhesive layer). In this type of arrangement, the thin glass layer helps protect the structural polymer layer from scratches.

[1003] If desired, one or more structures in layers 2.2-92 (e.g., coating 2.2-110, the layer forming layer 2.2-108, layer 2.2-112, optional layer 2.2-130, etc.) may be provided with dyes, pigments, or other colorants that produce a desired neutral hue (e.g., gray or black) or a non-neutral hue (e.g., red). Thin metal coatings, polarizers, and / or other structures may also be incorporated into layers 2.2-92 to help provide layers 2.2-92 with desired optical properties and / or a desired appearance.

[1004] If necessary, the portions of layer 2.2-92 that overlap with optical component 2.2-104 and / or other portions of layer 2.2-92 may be coated with a coating that helps prevent scratches that could adversely affect the optical quality of component 2.2-104. Figure 2.2-15 As shown, for example, the display overlay 2.2-92 may have a transparent layer such as transparent layer 2.2-116 (e.g., one or more polymer layers, glass layers, and / or other transparent layers such as...). Figure 2.2-14Layer 2.2-108). 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 of an inorganic material (e.g., oxides, nitrides, diamond-like carbon, etc.) that helps resist scratches. This type of method can be used, for example, to ensure that the portion of the display overlay layer 2.2-92 overlapping with the optical component 2.2-104 does not become hazy due to scratches when layer 2.2-116 is formed of a material such as a polymer that may be easily scratched when exposed to excessive friction from sharp external objects. Layer 2.2-118 may sometimes be referred to as a hard coating and may have a higher hardness (e.g., a higher Mohs hardness) compared to layer 2.2-116. Layer 2.2-118 may be a thin film coating having a thickness of less than 3 micrometers, less than 2 micrometers, less than 1 micrometer, less than 0.5 micrometers, or other suitable thickness.

[1005] Figure 2.2-16 The cross-sectional side view of the display cover 2.2-92 illustrates another way to help prevent undesirable scratches on the surfaces of the display cover 2.2-92 that overlap with the optical component 2.2-104. As demonstrated in this example, the outer surface of the display cover 2.2-92 may be provided with recesses such as recesses 2.2-120 (e.g., shallow circular recesses or recesses with a rectangular shape or other area). This places the recessed display cover surface 2.2-124 of the recesses 2.2-120 below the surrounding outer surface 2.2-122 of the layer 2.2-92. When the device 2.2-10 is placed on a desktop or other surface, the unrecessed portion of the surface of the layer 2.2-92 (outer surface 122) will contact the desktop surface and will thereby help prevent the desktop surface from contacting the recessed portion (surface 2.2-124) of the surface of the layer 2.2-92. Therefore, the recessed surface 2.2-124 overlapping with component 104 will remain scratch-free. Thus, even when layer 2.2-92 is exposed to excessive wear, haze will generally not occur in the area of ​​layer 2.2-92 overlapping with component 104.

[1006] Layer 2.2-92 may be formed of a material having optical properties compatible with the overlapping optical components 2.2-104. For example, if the optical components partially overlapped by layer 2.2-92 in the ineffective region IA are configured to operate at visible and infrared wavelengths, this portion of layer 2.2-92 may be provided with sufficient visible and infrared transparency to allow the overlapping components to operate satisfactorily at visible and infrared wavelengths. In arrangements where the material from the body of layer 2.2-92 does not have the desired optical properties for the optical components, an optical component window member (e.g., a window material disk, such as an infrared-transparent (and, if desired, visible-transparent) glass disk or other insert window member) may be mounted within an opening in layer 2.2-92 that overlaps with the optical components.

[1007] As an example, consider an arrangement in which layer 2.2-92 is transparent to visible light but has low transmittance at infrared wavelengths. Optical components in this type of arrangement can operate at infrared wavelengths. To ensure that the optical components can transmit and / or receive infrared light through layer 2.2-92, layer 2.2-92 may be provided with through-hole openings and infrared-transparent optical component window members, such as infrared-transparent disks. The infrared-transparent window members may be formed of a material different from the material forming layer 2.2-92 and may be mounted within the through-hole openings in layer 2.2-92. This type of arrangement in… Figure 2.2-17 As shown in the cross-sectional side view, the display cover layer 2.2-92 has an optical component window member 2.2-92W disposed in a through-hole opening in layer 2.2-92. Component 2.2-92W may be a glass optical component window member that is transparent to infrared light (and optionally transparent to visible light), while the surrounding portion of layer 2.2-92 may be formed of different materials (e.g., polymers, different glass materials, etc.). By providing an infrared-transparent window in layer 2.2-92, infrared optical components (e.g.,...) are... Figure 2.2-17 The optical component 2.2-102 can transmit and / or receive infrared light through the display overlay 2.2-92 (e.g., through a window in the display overlay), even when the layer 2.2-92 is formed of a non-infrared transparent material. This method can be used to provide an optical component window with any suitable optical properties (e.g., desired amounts of opacity, light transmittance, reflectivity, absorptivity and / or haze level, desired polarization properties, etc.) that differ from the optical properties of the rest of the layer 2.2-92.

[1008] 2.3: Systems with supplemental lighting

[1009] Figure 2.3-1 This is a cross-sectional side view of a head-mounted device in an exemplary configuration, wherein the device includes a lighting system for providing ambient lighting. Figure 2.3-1The head-mounted device 2.3-10 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 wavelengths, visible wavelengths, and / or infrared wavelengths.

[1010] Some cameras (e.g., cameras of the type sometimes referred to as scene cameras) can be used to capture images of the user's environment, which are displayed in real time on the display 2.3-14 (e.g., real-time pass-through video). Cameras in device 2.3-10 can also be used to track the position and movement of external objects. As an example, a tracking camera can track the user's hand (see, for example, hand 2.3-30H) or the user's torso or other body parts (see, for example, user body parts 2.3-30B). As an example, hand gesture input can be used to control the operation of device 2.3-10. Body part monitoring can be used to allow the user's body movements to be replicated by content displayed in the virtual environment. If desired, cameras can also be used to track the position of external accessories (e.g., the position and movement of the controller of device 2.3-10 moved by the user to control it). In some scenarios, a visual-inertial ranging (VIO) system or other systems for determining the position, movement, and / or orientation of device 2.3-10 relative to its surrounding environment can be formed by combining data from one or more cameras in device 2.3-10 with additional sensor data (e.g., data from an inertial measurement unit). Cameras may perform dedicated functions (tracking, visual-inertial ranging, scene capture, ranging, 3D image capture for face recognition and environment mapping, etc.), or two or more of these operations may be performed by a shared camera.

[1011] It may be desirable to allow users of device 2.3-10 to operate the device in low-light conditions. For example, a user might be viewing content on display 14 in a dark room or inside a dark vehicle. To ensure satisfactory performance of camera tracking functions such as hand tracking, body tracking, accessory tracking, and optionally other camera-based functions (e.g., visual-inertial ranging, etc.), device 2.3-10 may provide supplemental illumination. This supplemental illumination may be provided by a light source that generates supplemental ultraviolet, supplemental visible, and / or supplemental infrared light to enhance any available ambient light. In an exemplary configuration, supplemental illumination is provided at infrared wavelengths because this light is detectable by the tracking camera or other cameras with infrared sensing capabilities and is invisible to the human eye. Because supplemental 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) will not be disturbed by the presence of supplemental illumination.

[1012] Any suitable light source can be used to form the supplementary illumination system for devices 2.3-10 (e.g., light-emitting diodes, lasers, 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 nm to 1500 nm, at least 800 nm, 940 nm, at least 900 nm, 800 nm to 1200 nm, 900 nm to 1000 nm, 750 nm to 1100 nm, 800 nm to 1100 nm, less than 1500 nm, etc.). N cameras and M supplementary light sources may be present using the supplementary illumination in devices 2.3-10. The values ​​of N and M can 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 values. The value of N can be greater than the value of M, the value of N can be equal to the value of M, or the value of N can be less than the value of M. As an example, there may be four cameras using supplemental infrared illumination, and there may be two light sources emitting supplemental illumination.

[1013] Cameras using supplemental infrared illumination can be configured to be sensitive to the wavelengths of light emitted by the supplemental illumination system (e.g., infrared wavelengths associated with M supplemental light sources). The camera can also be sensitive to visible light wavelengths, allowing it to operate without any supplemental illumination when sufficient visible ambient light is present. To help avoid infrared interference during normal ambient light conditions, as an example, the supplemental illumination system can be configured to emit light in a narrow infrared band (e.g., 940 nm), and the camera can be equipped with a filter that allows visible light to pass through while blocking all infrared light except for light in the narrow infrared band. In another exemplary configuration, the camera is sensitive across the visible spectrum (e.g., 380 nm to 740 nm) and within the infrared spectrum (e.g., 740 nm to 1000 nm, or other suitable wider infrared wavelength bands where supplemental infrared illumination is generated). If desired, a switchable filter can be used to block infrared light from the camera when supplemental infrared illumination is not used and allow infrared light to pass through when supplemental infrared illumination is used.

[1014] like Figure 2.3-1As shown, the right-hand side of device 2.3-10 may include a first camera, such as camera 2.3-50, facing a direction such as direction 2.3-54 (e.g., -Z direction and slightly +Y direction, for example), and a second camera, such as camera 2.3-52 (sometimes referred to as a forward-facing camera), facing a forward direction such as direction 2.3-56 (e.g., +Y direction and slightly -Z direction, for example). The left-hand side of device 2.3-10 may have a corresponding pair of cameras oriented in the same manner. The viewing angles of the cameras on the left and right sides may be configured to overlap in front of device 2.3-10, such that there are no gaps in the coverage area 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- and / or downward-oriented camera that captures images when viewed outward from a position on the front side F of device 2.3-10). For example, a single tracking camera (e.g., camera 2.3-52) may be present on the right side of device 2.3-10 and a corresponding single tracking camera may be present on the left side of device 2.3-10.

[1015] Regardless of the number of tracking cameras positioned on each side of device 2.3-10, a right-hand infrared light source, such as light source 2.3-58, may be present to provide supplemental illumination (infrared light) in direction 2.3-60 for the tracking cameras on the right side of device 2.3-10 to illuminate objects such as hands 2.3-30H, bodies 2.3-30B, and other external objects. A corresponding left-hand infrared light source may also be present to provide supplemental infrared light for the tracking cameras on the left side of device 2.3-10. Using a single supplemental infrared light source on each side of device 2.3-10 to provide supplemental illumination for the tracking cameras on that side helps save space within the confined boundaries of housing 2.3-26.

[1016] The supplemental illumination system of device 2.3-10 can provide infrared illumination in areas larger than the area covered by the tracking camera of device 2.3-10 (angle range), in areas equal to or smaller than the area covered by the camera (angle range).

[1017] As an example, consider Figure 2.3-1 The coverage area of ​​the supplementary lighting system of equipment 2.3-10 in the YZ plane. For example... Figure 2.3-1As shown in the side view, the downward-facing camera 2.3-50 can be characterized by a viewing angle A1 in the YZ plane, and the forward-facing camera 2.3-52 can be characterized by a viewing angle A3 in the YZ plane. These viewing angles can be overlapped to provide continuous tracking coverage in the YZ plane. If desired, a single tracking camera can be used to provide the same amount of coverage or another suitable amount of coverage in the YZ plane. Figure 2.3-1 The examples are illustrative.

[1018] The supplemental illumination from light source 2.3-58 can be characterized by the illumination angle A2 in the YZ plane. The value of A2 can 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 the exemplary configuration, A2 is less than the total field of view of the tracking cameras and points outward in the forward and downward directions in front of device 2.3-10 (where hand and body tracking are most likely to occur). Using a slightly reduced illumination area for the supplemental illumination system (e.g., smaller than the area covered by the tracking camera system) helps save power when operating in dark environments for extended periods, while retaining the ability to track objects in all areas except the perimeter.

[1019] Figure 2.3-2 This is a top view of device 2.3-10, showing how device 2.3-10 can include cameras on both the left and right sides of support structure 2.3-26. The center of housing portion 2.3-26M may contain nose bridge portion 2.3-26NB. Nose bridge portion 2.3-26NB may include a lower edge with a curved shape configured to rest on the user's nose when device 2.3-10 is worn on the user's face. Nose bridge portion 2.3-26NB may couple right housing portion 2.3-26R to left housing portion 2.3-26L. Optical components 2.3-62 may include a lateral visible light camera, a forward visible light camera, a time-of-flight camera (e.g., a forward time-of-flight sensor in the bridge of the nose 2.3-26NM), a three-dimensional structured light camera (e.g., a left structured light camera and a right structured light camera adjacent to the bridge of the nose 2.3-26NB), a scintillation sensor for detecting ambient light fluctuations (e.g., 60Hz fluctuations associated with indoor artificial lighting), an ambient light sensor, etc.

[1020] The right camera 2.3-52 can be supported in the right housing portion 2.3-26R, and the corresponding left camera 2.3-52' can be supported in the left housing portion 2.3-26L. Similarly, optional additional right cameras such as Figure 2.3-1The camera 2.3-50 can be supported in the right housing portion 2.3-26R, and the corresponding optional additional left camera can be supported in the left housing portion 2.3-26L. In this type of configuration, supplementary illumination for a single right-side tracking camera or a pair of right-side tracking cameras can be provided by the right supplementary light source 2.3-58, and supplementary illumination for the left-side camera can be provided by the left supplementary light source 2.3-58'.

[1021] During supplemental lighting operation, light sources 2.3-58 and 2.3-58' produce supplemental lighting in directions 2.3-60 and 2.3-60', respectively. (As combined...) Figure 2.3-1 As described above regarding the relative coverage areas of the camera and the light source, the illumination coverage area of ​​the supplementary lighting system need not precisely match the coverage area of ​​the camera. For example, the tracking camera on each side of device 2.3-10 can be characterized by a viewing angle in the XY plane that is larger than the coverage angle of the associated light source. Arrangements can also be used where illumination from supplementary light sources on each side of device 2.3-10 is provided within the same angular range as the camera's viewing angle, or where illumination is provided within an angular range wider than the camera's viewing angle.

[1022] Supplemental lighting can be provided globally over a relatively large, fixed area, or a narrower beam of light can be activated or moved toward or across the desired area to cover it. If needed, a dynamic lighting system with a manipulated or addressable supplemental light beam can control or activate the beam so that it follows the user's hand or other object of interest. This avoids unnecessarily consuming power to illuminate areas that do not contain the object being tracked.

[1023] Figure 2.3-5 and Figure 2.3-6 This is a side view of an illustrative fixed area supplementary lighting source. Figure 2.3-3 The exemplary light source 2.3-58 has a semiconductor light-emitting device 2.3-70. Device 2.3-70 can be a solid-state light-emitting device, such as a light-emitting diode, a superluminescent light-emitting diode, a resonant cavity light-emitting diode, a side-emitting light-emitting diode, or a vertical cavity surface-emitting diode, and can be a diode-pumped laser, such as a diode-pumped fiber laser or other diode-pumped lasers. Figure 2.3-3 As shown, device 2.3-70 can be mounted on optional interposer 2.3-72 (e.g., using solder). Interposer 2.3-72 can be mounted to package substrate 2.3-74 (e.g., printed circuit). During operation, device 2.3-70 can emit infrared light that diffuses over the desired illumination area through one or more optical structures overlapping device 2.3-70. Figure 2.3-3In the examples, these optical structures include optional overmolded polymer lenses 3.3-76 and optional secondary optical structures such as peanut-shaped lenses 3.3-78. Bending reflective optical structures can also be formed on the intercalator 2.3-76 or substrate 2.3-74 to enhance sidelight and / or backlight retrace. Optical structures overlapping with device 2.3-70 can be used to shape 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). If desired, safety enhancement structures such as resistive safety traces or capacitive traces can be embedded in or overlapped with the optics, or photodetectors can be used to form a closed loop with safety interlocking on the light source driver (e.g., with combined...). Figures 2.3-5 to 2.3-8 (This relates to the module architecture of the type shown).

[1024] exist Figure 2.3-4 In the exemplary configuration, 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. 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 an optional interposer 2.3-72 on a printed circuit board or other substrate. During operation, Figure 2.3-4 The device 2.3-70 can emit infrared light in an upward direction, which is laterally diffused by the beam shaping layer 2.3-82 to cover the desired illumination area (e.g., + / -60° or other suitable angular range).

[1025] Generally speaking, any suitable optical component that serves as a light diffusion structure can be combined with... Figure 2.3-5 and Figure 2.3-6 Devices 2.3-70 are overlapped. These optical components may include optical components such as refractive beam shaping optics, diffractive optics, diffuse optics, optical nanostructures (e.g., thin two-dimensional metamaterial layers, such as patterned structures of phototransparent dielectrics with subwavelength dimensions, these patterned structures forming metasurfaces configured to diffuse the emitted beam), curved reflectors, etc. When forming the light source 2.3-58, multiple devices 2.3-70 may be mounted in a common package, and / or multiple packaged devices 2.3-70 may be mounted adjacent to each other on a printed circuit. Figure 2.3-5 and Figure 2.3-6 The example using a single light-emitting device 2.3-70 to form a light source 58 is illustrative.

[1026] Figure 2.3-7 and Figure 2.3-8 This is a side view of an exemplary dynamic pattern illuminator that can be used in the lighting systems of devices 2.3-10. (Using...) Figure 2.3-7 and Figure 2.3-8The light source of the type shown, control circuit 2.3-12 can selectively activate or manipulate the emitted infrared beam, so as to provide target supplemental illumination to one or more objects of interest.

[1027] exist Figure 2.3-5 In the example, light source 2.3-58 has an array of light-emitting devices 2.3-70. Devices 2.3-70 may include multiple semiconductor dies mounted in a package 2.3-86 on a substrate such as printed circuit board 2.3-84, and may include multiple individually addressable emitters, or may include multiple individually addressable segments of emitters mounted in a package 2.3-86 on a substrate such as silicon, ceramic, printed circuit board 2.3-84, or other substrate. A partitioned beam shaper layer or other optical component such as layer 2.3-88 may overlap with device 2.3-70. Layer 2.3-88 may have multiple regions, each with a corresponding beam manipulation and beam shaping optical structure. These structures may be refractive structures, diffractive structures, nanostructures, etc. Structures with vertically aligned or misaligned regions on both surfaces of layer 2.3-88 and / or multiple layers of layer 2.3-88 may be employed. Each region can be used to manipulate and shape the beam emitted from the corresponding light-emitting device in different corresponding directions. For example, the first region can guide a beam emitted vertically from the first device 2.3-70 to the left, while the second region can guide a beam emitted vertically from the second device 2.3-70 to the right. By overlapping the array of individually controlled devices 70 with a corresponding array of individualized beam manipulation structures, each device 2.3-70 can be configured to emit a beam in a different corresponding direction (see, for example, illustrative beams 2.3-90), thereby directing... Figure 2.3-5 Light source 2.3-58 provides the ability to emit manipulated beams. The emission area of ​​each beam can overlap with that of adjacent beams to avoid possible gaps in coverage. Beams 2.3-90 can all be emitted simultaneously, or one or more selected beams 2.3-90 can be emitted at a time. If desired, beams 2.3-90 can be emitted sequentially (e.g., scanning beams emitted from light source 58 across the region of interest).

[1028] Figure 2.3-6 Another exemplary light source is shown in the figure, which can be used to form a supplementary lighting system for devices 2.3-10. Figure 2.3-6The light source 2.3-58 may have one or more light-emitting devices, such as a device 2.3-70 that emits one or more light beams, such as beam 2.3-92 (e.g., an infrared beam). Device 2.3-70 may be mounted in a package 2.3-96 on a printed circuit board or other substrate 2.3-94. The electro-optical beam manipulator 2.3-98 may have one or more beam manipulators, such as a microelectromechanical system reflector 2.3-100 or other electrically adjustable beam manipulators controlled by control signals from control circuitry 2.3-12. When light is desired to be emitted in a first direction, the reflector 2.3-100 may be positioned in a first orientation to reflect beam 2.3-92 to produce a first emitted beam 2.3-102. When light is desired to be emitted in a second direction, the reflector 2.3-100 may be positioned in a second orientation different from the first orientation to reflect beam 2.3-92 to produce a second emitted beam 2.3-104. The reflectors 2.3-100 can 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 other suitable numbers). The reflectors 2.3-100 can be rotated about a single axis (to change the angle of the emitted beam along a single dimension) or can be rotated about two axes (e.g., to arbitrarily change the angle of the emitted beam in two dimensions). If desired, beam-shaping optics (e.g., beam collimating lenses, etc.) can be incorporated into the beam manipulator 2.3-98 to help ensure that the manipulated beam has the desired intensity profile.

[1029] If needed, a hybrid illuminator architecture can be used, allowing selective activation of multiple channels of device 2.3-70 or a combination thereof. Figure 2.3-5 The multiple channels of the aforementioned devices 2.3-70 are used to manipulate optical devices such as light beams. Figure 2.3-6 The 2.3-100 reflector provides one or more additional dimensions of dynamic lighting.

[1030] Light sources that emit static wide-area beams (see, for example) Figure 2.3-5 and Figure 2.3-6 The exemplary light source 2.3-58 can be configured to emit a beam of any suitable shape to help provide supplemental illumination for the tracking camera of device 2.3-10. Figure 2.3-7This illustrates how light source 2.3-58 can be configured to emit a circular beam of field of view (FoG) such as circular beam 2.3-110 (e.g., an infrared beam with a full width at half maximum (FWHM) intensity characterized by an angular span of + / -60° or other suitable coverage area) or can be configured to emit a rectangular beam of FoG such as rectangular beam 2.3-112 with a similar vertical angular span and a smaller horizontal angular span. Two rectangular beams, such as beam 2.3-112, can be generated side-by-side to provide sufficient horizontal illumination coverage for both the left and right cameras in device 2.3-10 (as an example).

[1031] In most general 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 the desired FWHM 2D FoG, a uniform far-field density at each instantaneous FoG (iFoG) can be achieved to provide uniform illumination and working range for the cameras. However, there are situations where a non-uniform far-field intensity distribution may be desired. For example, a symmetrical “batwing” intensity distribution can be used to compensate for the relative intensity drop of the camera image sensor when the illuminated target is flat or when camera vignetting is significant. Other examples include asymmetric intensity distributions for: cameras aligned non-coaxially relative to the illumination system; targets with asymmetrical appearance / residence across the FoG, such as hands; multiple illuminators with overlapping FoGs; multiple non-coaxial cameras; irregular occlusion at specific FoG regions; etc.

[1032] Figure 2.3-10 The graph in Figure 2.3-11 illustrates an exemplary beam output (angular beam distribution) associated with a dynamically adjustable lighting system. Figure 2.3-8 In the example, the light source is such as Figure 2.3-5 Light source 58 or Figure 2.3-6 The light source 58 has been configured to produce a beam with an elongated rectangular shape (e.g., a rectangle with a horizontal span greater than its vertical span). Using beam manipulation, the light source 2.3-58 can be positioned in one or more vertical locations, such as Figure 2.3-8 The elongated rectangular beam is emitted from the exemplary position 2.3-114. Figure 2.3-5 In the arrangement shown, each light-emitting device 2.3-70 can produce a different corresponding elongated rectangular beam, each of these elongated rectangular beams being associated with a different vertical positioning in the output of the light source 2.3-58. One or more of these beams can be emitted simultaneously by activating one or more corresponding light-emitting devices 2.3-70. Figure 2.3-6 In the arrangement shown, the light-emitting device 2.3-70 can produce, for example... Figure 2.3-6 The beam 2.3-92, which is manipulated by beam manipulator 2.3-98 to a desired position (e.g., Figure 2.3-8(Example locations 2.3-114) and / or other locations, thereby providing the desired coverage for the light source 2.3-58.

[1033] exist Figure 2.3-8 In the exemplary example, light is output over a vertical angular range larger than the horizontal range. An additional light source (e.g., a light source on the opposite side of device 2.3-10) can be used to supply additional horizontal coverage. In this way, the desired angular output range (e.g., + / - 60° or other suitable angular output range in both the horizontal and vertical dimensions) can be covered.

[1034] exist Figure 2.3-9 In the exemplary configuration, light source 2.3-58 (e.g., dynamically configured light sources such as...) Figure 2.3-5 or Figure 2.3-6 The light source 58) is configured to supply a relatively small circular or square output beam that can be manipulated in both the horizontal and vertical dimensions to produce the desired total coverage.

[1035] 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) manner or in an analog manner (e.g., by continuously or stepwise adjusting the output power between more than two different output levels). Figure 2.3-9 As shown, for example, no light may be output in certain portions of the coverage area such as regions 2.3-116 (e.g., the beam power may be zero for these regions), full-power light may be output in regions such as regions 2.3-118 (e.g., the beam power may be maximized for these regions), and intermediate power levels may be used when supplying output light to other regions such as regions 2.3-120 that are closely adjacent to regions 2.3-118.

[1036] The arrangement of outputting full-power light only in a subset of the total coverage area of ​​light source 58 helps devices 2.3-10 utilize power efficiently. For example... Figure 2.3-9 As illustrated in the diagram, 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. As an example, device 2.3-10 may track a user's hand or other external objects. When these objects are relatively small compared to the total field of view of the camera in device 2.3-10, power can be saved by limiting the output of supplemental illumination (or at least limiting the output of full-power supplemental illumination) to only those areas overlapping with the tracked external objects.

[1037] exist Figure 2.3-9In the example, object 2.3-122 (e.g., a user's hand or other body part, or other objects in the user's environment) is being actively tracked by device 2.3-10. Therefore, the supplemental lighting system of device 2.3-10 is being used to provide full-power illumination to area 2.3-118, which overlaps with object 2.3-122. Elsewhere in the coverage area of ​​the luminous device 58, the beam power is reduced (see, for example, intermediate power area 2.3-120) or completely turned off (see, for example, unlit area 2.3-116). This type of method can be used for scanning beam arrangements (e.g., using a combination of...). Figure 2.3-6 The aforementioned scanning mirror device or other beam manipulator) or a light source using an addressable array having device 70 (e.g., Figure 2.3-5 (58) Light sources, each of which can provide output in different directions.

[1038] In such Figure 2.3-9 In areas 2.3-116, there is no supplemental lighting, so objects in those areas will not receive supplemental lighting. However, once an object such as object 2.3-122 is being tracked, device 2.3-10 can monitor the positioning and direction of movement of object 2.3-122 in real time. This allows device 2.3-10 to provide full-power supplemental lighting to areas overlapping with object 2.3-122, and to provide intermediate-power (or full-power, if needed) supplemental lighting to portions of the output area of ​​light source 58 that are closely adjacent to object 2.3-122 (e.g., areas where object 2.3-122 may move and / or areas predicted to be occupied in the near future based on tracked movement). If the positioning of object 2.3-122 moves to one of those adjacent areas, device 2.3-10 can increase the supplemental lighting in those areas to full power and can update the beam power so that the adjacent areas again have intermediate-power level coverage.

[1039] Although the two-dimensional scanning beams from light sources 2.3-58 in Figures 7 and 8 have been described Figure 2.3-9 The multi-power horizontal beam scheme, but such adjustable power output schemes can also be used with light sources 2.3-58 that provide a one-dimensional adjustable directional light source (e.g., generating...). Figure 2.3-8 The supplementary lighting slice light source of the type shown can be used together and / or can be used with a fixed area light source. In a fixed area light source scheme, for example, Figure 2.3-3 or Figure 2.3-4 The right-hand light source 58 of the type shown can be used to supply supplemental illumination for tracking objects 2.3-122 in front of the right-hand camera of device 2.3-10, while Figure 2.3-3 or Figure 2.3-4The left-hand light source 58 of the type shown can be used to provide supplemental illumination for tracking an object 2.3-122 in front of the left-hand camera of device 2.3-10. Device 2.3-10 can activate either the right-hand light source or the left-hand light source, or both, depending on the current and expected position of object 2.3-122.

[1040] Another way to help use power efficiently for supplemental lighting systems involves using the light source 2.3-58 to generate supplemental lighting only when the camera providing it would benefit from it. For example, under bright lighting conditions, ambient visible light will provide sufficient illumination, so the supplemental infrared beam can be turned off (or at least its power reduced to a level lower than otherwise used) to help save power. Activation of supplemental lighting can occur when dim ambient lighting conditions are detected or when other suitable conditions that trigger the generation of supplemental lighting are detected.

[1041] Figure 2.3-10 This is a flowchart illustrating the exemplary operations involving electronic device 2.3-10. During the operation of block 2.3-150, device 2.3-10 can be used to provide content such as visual content, audio content, and other outputs to the user. As an example, device 2.3-10 can be worn on the user's head while presenting images for viewing. The operations of block 2.3-150 can be performed when device 2.3-10 is in a normal operating environment with a satisfactory level of visible ambient light.

[1042] Visual content can be presented to the user on display 2.3-14. This visual content may include camera images (e.g., pass-through video) and / or other content from the camera in device 2.3-10. In some scenarios, computer-generated content (sometimes referred to as virtual content) may be overlaid on top of real-world content from the camera in device 2.3-10. In this type of mixed reality environment, camera data can be used to help track the position of the user's hands and other real-world objects and thereby help register the overlay of virtual content on the real-world image. For example, by tracking the position of the user's hands, an image of a computer-generated glove can be accurately overlaid on top of a real-world image of the user's hands. By tracking the position of a table surface, a computer-generated image can be placed on top of 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 other body part movements (sometimes referred to as air gestures) that act as user input can be used to control the operation of device 2.3-10 (e.g., in mixed reality or fully virtual environments).

[1043] Device 2.3-10 may have any suitable number of cameras, including: 3D 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 operations, act as part of a visual-inertial ranging system, and / or otherwise support the operation of Device 2.3-10. The cameras of Device 2.3-10 may be oriented forward, downward, sideways, upward, backward, and / or in multiple directions. Some cameras may operate only at visible wavelengths. Other cameras may operate at both visible and infrared wavelengths.

[1044] As illustrated in conjunction with Figures 3 and 4, as an example, device 2.3-10 may have one or more tracking cameras on each side of device 2.3-10. These cameras may be sensitive to visible and infrared wavelengths and may 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 ranging system). The tracking cameras may be sensitive to visible and infrared wavelengths, such as wavelengths from 400 nm to 1000 nm, 400 nm to 740 nm, and 940 nm, or other suitable visible and infrared wavelengths. The infrared sensitivity of the tracking cameras is preferably consistent with one or more wavelengths emitted by light source 2.3-58 in the supplemental illumination system, thereby allowing these cameras to operate when most or all available illumination is provided by light source 2.3-58 rather than ambient light sources.

[1045] Supplemental lighting can be provided continuously if needed. An arrangement in which power is saved by at least occasionally disconnecting the supplemental lighting system is described herein as an example. In the configuration for device 2.3-10 in which supplemental lighting is turned on and off, device 2.3-10 can monitor the occurrence of conditions that indicate the supplemental lighting should be turned on so that the camera (e.g., a tracking camera) can operate satisfactorily during operation of block 2.3-150. These monitoring activities can occur when the camera (e.g., a tracking camera) of device 2.3-10 is operating normally in the absence of supplemental lighting from the supplemental lighting system.

[1046] Any suitable triggering criterion can be used to determine when to activate the supplemental lighting system by turning on light source 2.3-58. As an example, device 2.3-10 may include an ambient light sensor. The ambient light sensor measures the amount of visible ambient light present in the environment surrounding device 2.3-10. Thresholds or other criteria can be applied to the ambient light readings from the ambient light sensor. In response to determining that the ambient light level is below a predetermined ambient light threshold or otherwise too dim to allow the tracking camera to operate satisfactorily, control circuitry 12 may turn on light source 2.3-58 to provide supplemental illumination (e.g., infrared light).

[1047] Another exemplary criterion that can be used to determine when to activate supplemental illumination involves evaluating a quality metric of the image processing algorithm. During operation of boxes 2.3-150, the captured image may be processed by one or more image processing algorithms. As an example, these algorithms may include a hand tracking algorithm. The hand tracking algorithm may produce a quality factor or other metrics indicating the ability of the hand tracking algorithm to satisfactorily track the user's hand. In response to detecting that the quality metric of the tracking algorithm is below a desired threshold, control circuitry 12 may turn on light source 2.3-58 to provide supplemental illumination to the camera.

[1048] If needed, the tracking camera or other image sensor hardware can provide information indicating that performance is being adversely affected by low ambient lighting levels. For example, frames of image data can be evaluated to determine if the lighting level is low. The output of the tracking camera hardware in device 2.3-10 can also indicate whether the signal-to-noise ratio level is satisfactory. If the tracking camera is producing only dark and / or noisy image data, control circuitry 12 can determine that light source 2.3-58 should be turned on.

[1049] In some arrangements, device 2.3-10 may be configured to determine the position of a user relative to walls and other obstacles in the user's environment. As an example, device 2.3-10 may contain a map of known wall positions (e.g., a map obtained from an external source or a map based on a previous map-building operation performed by device 2.3-10 when the user is walking through a building or other environment while wearing device 2.3-10). Satellite navigation system circuitry (e.g., Global Positioning System circuitry) may use satellite signals to determine the position of device 2.3-10 (e.g., the position of device 2.3-10 relative to building walls and other obstacles). Based on the user's known position and movement, and using information about the positions of known obstacles (such as walls), device 2.3-10 may predict when the user is likely to approach a wall or other obstacle. Sensors 16 in device 2.3-10 (such as proximity sensors, time-of-flight sensors, radar, LiDAR, etc.) may also be used to monitor the user's movement relative to walls and other obstacles. By combining some or all of the additional information about the operating environment of device 2.3-10 (e.g., ambient light readings indicating dim ambient light), device 2.3-10 can determine when light source 2.3-58 should be turned on to provide supplemental illumination to help ensure that the tracking camera of device 2.3-10 will operate satisfactorily. This helps ensure that the camera of device 2.3-10 can use the infrared illumination of light source 2.3-58 to track the position of obstacles in the user's environment. By accurately tracking the position of obstacles, these obstacles or alerts about their presence can be displayed on display 2.3-14 to help the user avoid unwanted collisions with obstacles.

[1050] If needed, multiple electronic devices 2.3-10 in system 2.3-8 can monitor conditions indicating the need for supplemental lighting. For example, multiple user-wearable head-mounted devices, and one device may detect a low level of ambient lighting before another. In this type of system, any device that detects a low level of ambient lighting can signal to other devices in the system to request supplemental lighting. In response, one or more of the other devices can provide supplemental lighting to assist the requesting device's camera in capturing images. Thus, supplemental lighting systems of different devices can assist each other by contributing and sharing supplemental lighting. This could allow wall-mounted devices to help provide supplemental lighting for battery-powered devices, or it could allow electronic devices closer to the tracked object to provide supplemental lighting to that object more effectively than those farther away (as an example).

[1051] As long as no conditions for triggering supplemental lighting are detected, device 2.3-10 (e.g., control circuit 12) may continue to monitor conditions that meet the supplemental lighting trigger criteria (e.g., dim ambient light, reduced image processing quality of the tracking camera, reduced camera hardware performance, obstacle proximity criteria, requests from other devices, etc.) during operation of block 2.3-150.

[1052] If the trigger criteria are met, processing can proceed to block 2.3-152. During operation of block 2.3-152, control circuitry 2.3-14 may use a supplemental illumination system to provide supplemental illumination for the camera (e.g., illuminating external objects in the field of view of the tracking camera with infrared light emitted by light source 2.3-58). While providing supplemental illumination, the power of the infrared light emitted by each light source 2.3-58 and / or the direction of the beam 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, the emitted beam may be directed to an area containing the tracked object (e.g., a known location of a user's hand or other external object of interest tracked by the tracking camera) and / or adjacent areas, and the emitted power level may be adjusted stepwise or continuously (e.g., to provide sufficient supplemental illumination to ensure satisfactory tracking camera operation without providing excessive illumination), and so on.

[1053] Light sources configured to provide illumination over a fixed area, such as Figure 2.3-5 and Figure 2.3-6 Light source 2.3-58 can be turned on to ensure that objects in these fixed areas are illuminated. Light sources emitting controllable beams, such as... Figure 2.3-5 and Figure 2.3-8The light source 2.3-58 can be used to emit supplemental illumination over a relatively large area (e.g., by scanning a beam across a large area or by illuminating different corresponding parts of a large area by using multiple smaller beams simultaneously), or it can be used to emit supplemental illumination to a specific location (such as the location containing the hand of the user being tracked or other objects).

[1054] This can provide supplemental illumination for cameras tracking user body parts, cameras tracking the position of attached objects, cameras capturing pass-through video, cameras forming part of a visual-inertial ranging system, and / or other optical components that collect light from objects near device 2.3-10. If desired, light source 2.3-58 can be configured to emit structured light (e.g., lines, points, features, etc., distributed in a pseudo-random pattern). For example, structured light can be used in scenarios where a tracking camera acquires 3D images.

[1055] During operation of box 2.3-152, device 2.3-10 may monitor conditions indicating that supplemental lighting is no longer needed. Control circuitry 2.3-12 may, for example, monitor to determine whether supplemental lighting triggering conditions are no longer met. As long as dim ambient lighting conditions or other conditions indicating that supplemental lighting should be provided continue to exist, device 2.3-10 may continue to use light source 2.3-58 to provide supplemental lighting. If dim lighting conditions cease or it is determined that other conditions for which supplemental lighting is desired no longer exist, device 2.3-10 may shut down the supplemental lighting system. Specifically, control circuitry 2.3-12 may shut down light source 2.3-58 during operation of box 156. As indicated by line 2.3-152, operation may then return to box 2.3-150.

[1056] 2.4: Systems with concealed displays and sensors

[1057] Figure 2.4-1 This is a front view of device 2.4-10 in an exemplary configuration, where device 2.4-10 has a common viewable display such as a front-facing display 2.4-14F. Figure 2.4-1 As shown, the support structure 2.4-16M of device 2.4-10 may have a right portion and a left portion such as portions 2.4-16R and 2.4-16L, which are coupled via an inserted nose bridge portion such as portion 2.4-16NB. Portion 2.4-16NB may have a curved external surface such as nose bridge surface 2.4-90, which is configured to receive and rest on the user's nose to help support the main housing portion 2.4-16M on the user's head.

[1058] The display 2.4-14F may have active areas configured to display images, such as an active area AA, and inactive areas IA where no images are displayed. The active area AA may be rectangular, a rectangle with rounded corners, may have teardrop-shaped portions on the left and right sides of the device 2.4-10, may have a shape with straight edges, a shape with curved edges, a shape with peripheral edges having both straight and curved portions, and / or other suitable shapes. Figure 2.4-1 As shown, the effective area AA may have a curved recessed portion at the bridge portion 2.4-16NB of the main housing portion 2.4-16. The presence of the nose-shaped recess in the effective area AA helps to fit the effective area AA within the available space of the housing portion 2.4-16M without unduly restricting the size of the effective area AA.

[1059] The effective area AA contains a pixel array. Pixels can be, for example, light-emitting diode pixels formed on a flexible display panel substrate using thin-film organic light-emitting diodes or crystalline semiconductor light-emitting diode dies (sometimes referred to as micro-light-emitting diodes). If desired, configurations in which displays 2.4-14F utilize other display technologies may also be used. In this document, exemplary arrangements in which displays 14 are formed of light-emitting diode displays, such as organic light-emitting diode displays formed on a flexible substrate (e.g., a substrate formed from a bendable polyimide layer or other flexible polymer sheet), are sometimes described as examples. The pixels of the effective area AA can be in display devices such as… Figure 2.4-1 It is formed on a display panel 2.4-14P (e.g., a flexible organic light-emitting diode display panel). In some configurations, the shape of the effective area AA (and, if desired, the panel 2.4-14P) may have a peripheral edge comprising straight segments or a combination of straight and curved segments. A configuration in which the entire shape of the effective area AA (and optionally, the panel 2.4-14P) is characterized by a curved peripheral edge may also be used.

[1060] The 2.4-14F display may have invalid areas, such as invalid area IA, that do not contain pixels and do not display images. Invalid area IA may form an invalid boundary area extending along one or more portions of the peripheral edge of the valid area AA. Figure 2.4-1 In an exemplary configuration, the invalid region IA has an annular shape surrounding the valid region AA and forming an invalid boundary. In this type of arrangement, the width of the invalid region IA can be relatively constant, and the inner and outer edges of the region IA can be characterized by straight and / or curved segments, or can be curved along the entire length of the edge. For example, the outer edge of the region IA (e.g., the periphery of the display 2.4-14F) can have a curved profile extending parallel to the curved edge of the valid region AA.

[1061] In some configurations, device 2.4-10 may operate in conjunction with other devices in system 2.4-8, such as wireless controllers and other accessories. These accessories may have magnetic sensors that sense the direction and intensity of magnetic fields. Device 2.4-10 may have one or more electromagnets configured to emit magnetic fields. The magnetic field may be measured by wireless accessories near device 2.4-10, allowing the accessories to determine their orientation and location relative to device 2.4-10. This allows the accessories to wirelessly provide device 2.4-10 with real-time information about their current location, orientation, and movement, enabling the accessories to act as wireless controllers. Accessories may include wearable devices, handheld devices, and other input devices.

[1062] In an exemplary configuration, device 2.4-10 may have a coil, such as exemplary coil 2.4-54, extending around the periphery of display 2.4-14F (e.g., below the inactive area IA or other portion of display 2.4-14F). Coil 2.4-54 may have any suitable number of turns (e.g., 1-10, at least 2, at least 5, at least 10, 10-50, less than 100, less than 25, less than 6, etc.). These turns may be formed on a substrate by metal traces, by wires, and / or by other conductive lines. During operation, control circuitry 2.4-12 may supply an alternating current (AC) drive signal to coil 2.4-54. The drive signal may have a frequency of 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 (as an example). When AC current flows through coil 2.4-54, a corresponding magnetic field is generated near device 2.4-10. Electronic devices located near device 2.4-10, such as wireless controllers with magnetic sensors, can use the magnetic field as a reference, allowing the wireless controllers to determine their orientation, positioning, and / or movement relative to device 2.4-10 to provide input to device 2.4-10 as they move.

[1063] As an example, consider a handheld wireless controller used to control the operation of device 2.4-10. During operation, device 2.4-10 uses coil 2.4-54 to emit a magnetic field. When the handheld wireless controller is moved, the controller's magnetic sensor can monitor the controller's position and movement relative to device 2.4-10 by monitoring the strength, orientation, and changes in strength and / or orientation of the magnetic field emitted by coil 2.4-54 as the user moves the controller through the air. The electronic device can then wirelessly transmit information about the controller's position and orientation to device 2.4-10. In this way, the user can manipulate the handheld controller, wearable controller, or other external accessories to provide air gestures, pointing inputs, manipulation inputs, and / or other user inputs to device 2.4-10.

[1064] Device 2.4-10 may have components such as optical components (e.g., Figure 2.4-1 The components of the optical sensor in sensor 2.4-16 are included. These components can be mounted in any suitable location on the head-mounted 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 can face rearward (e.g., when mounted on the back of device 2.4-10), face sideways (e.g., left or right), face downward or upward, face the front of device 2.4-10 (e.g., when mounted on the front of device 2.4-10), can be mounted to any combination of these directions (e.g., forward, right, and downward) and / or can be mounted in other suitable orientations. In an exemplary configuration, at least some of the components of device 2.4-10 are mounted outward and forward (and optionally facing sideways and / or upward and downward). For example, the forward-facing cameras for pass-through video can be configured to be mounted on the left and right sides of the front of the device 2.4-10, in which the cameras are slightly diverged along the horizontal dimension, such that the fields of view of these cameras overlap to some extent when capturing a wide-angle image of the environment in front of the device 2.4-10. If desired, the captured image may include portions of the user's surrounding environment below, above, and to the sides of the area directly in front of the device 2.4-10.

[1065] To help conceal components such as optical elements from being seen from the outside of the device 2.4-10, it may be desirable to utilize an aesthetically pleasing overlay structure to cover some or all of these components. The overlay structure may include transparent portions (e.g., windows for optical elements) characterized by sufficient optical transparency to allow the overlapping optical elements to operate satisfactorily. For example, an ambient light sensor may be covered with a layer that appears opaque to an external viewer to help conceal the sensor from view, but allows sufficient ambient light to pass through to enable satisfactory ambient light measurements. As another example, optical elements emitting infrared light may be overlapped with a visually opaque material that is transparent to infrared light.

[1066] In the exemplary configuration, the optical components of device 2.4-10 can be mounted on... Figure 2.4-1In the invalid region IA, the aesthetic overlay structure can be formed as an annular shape overlapping the optical components in the invalid region IA. The aesthetic overlay structure can be formed from ink, polymer structures, including metals, glass, other materials, and / or combinations of these materials. In an exemplary configuration, the aesthetic overlay structure can be formed from an annular member having an area matching the occupied area of ​​the invalid region IA. For example, if the valid region AA includes a left and right portion having a teardrop shape, the annular member can have a curved edge following the curved periphery of the teardrop-shaped portion of the valid region AA. The annular member can be formed from one or more polymer structures (e.g., the annular member can be formed from a polymer ring). Because the annular member helps to conceal the overlapping components so that they are not visible, the annular member is sometimes referred to as a shield or annular shield member. The appearance of the shield or other aesthetic overlay structure can be characterized by neutral colors (white, black, or gray) or non-neutral colors (e.g., blue, red, green, gold, rose gold, etc.).

[1067] If required, the display 2.4-14F may have a protective display overlay. The overlay may overlap with the active area AA and the inactive area IA (e.g., in the area from...). Figure 2.4-1 When viewing in the direction 2.4-52, the entire front surface of the device 2.4-10 may be covered by a cover layer. The cover layer, sometimes referred to as the shell wall or transparent shell wall, may have a rectangular shape, a shape with teardrop portions, an elliptical shape, or other shapes with curved and / or straight edges.

[1068] The cover layer can be formed from transparent materials such as glass, polymers, transparent crystalline materials such as sapphire, light-transmitting ceramics, other transparent materials, and / or combinations of these materials. As an example, the protective display cover layer of a display 2.4-14F can be formed from safety glass (e.g., laminated glass comprising a light-transmitting glass layer and a laminated polymer film). Optional coatings can be applied to the surface of the display cover layer. If desired, the display cover layer can be chemically strengthened (e.g., using an ion-exchange process to produce a scratch-resistant outer material layer under compressive stress). In some configurations, the display cover layer can 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 rigid polymer layer coupled to a glass layer or another rigid polymer layer, etc.) to enhance the performance of the cover layer.

[1069] In the effective area AA, the display overlay may overlap with the pixels of the display panel 2.4-14P. The display overlay in the effective area AA is preferably transparent to allow viewing of the image presented on the display panel 2.4-14P. In the ineffective area IA, the display overlay may overlap with a ring-shaped shield or other aesthetically pleasing covering structure. The shield and / or other covering structure (e.g., an opaque ink coating on the inner surface of the display overlay and / or structure) may be sufficiently opaque to help conceal some or all of the optical components in the ineffective area IA from being seen. Windows may be provided in the shield or other aesthetically pleasing covering structure to help ensure satisfactory operation of the optical components overlapped by these structures. Windows may be formed by apertures, by areas of the shield or other aesthetically pleasing covering structure that have been locally thinned to enhance light transmittance, by window members with desired light transmittance properties already inserted into mating openings in the shield, and / or by other shield window structures.

[1070] exist Figure 2.4-1 In the example, device 2.4-10 includes optical components, such as 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 (as examples). These optical components (e.g., from...) Figure 2.4-1 Each optical component in the selected optical sensors, light-emitting devices, etc. (as per sensor 2.4-16) can be configured to detect light and, if necessary, to emit light (e.g., ultraviolet, visible, and / or infrared light).

[1071] In an exemplary configuration, optical component 2.4-60 can sense ambient light (e.g., visible ambient light). Specifically, optical component 2.4-60 may have a photodetector that senses changes in ambient light intensity over time. As an example, if a 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., 60 Hz AC mains). The photodetector of component 2.4-60 can sense the artificial light from the artificial light source, characterized by intensity fluctuations at 60 Hz. Control circuitry 2.4-12 can use this information to adjust clocks or other timing signals associated with the operation of the image sensor in device 2.4-10 to help avoid unwanted interference between the light source frequency and the frame rate or other frequencies associated with image capture operation. Control circuitry 2.4-12 can also use measurements from component 2.4-60 to help identify the presence and type of artificial light. In this way, control circuitry 2.4-12 can detect the presence of light, such as fluorescence or other light with known non-ideal color characteristics, and can compensate for color shifts (e.g., white point adjustment) in color-sensitive components such as cameras and displays. Because optical component 2.4-60 measures fluctuations in light intensity, component 2.4-60 is sometimes referred to as a flicker sensor or ambient light frequency sensor.

[1072] 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 monochromatic sensor that measures the intensity of ambient light. In a multi-photodetector configuration, each photodetector may be composed of overlapping optical filters that allow different wavelength bands (e.g., different visible and / or infrared passbands) to pass through. The optical filter passbands may overlap at their edges. This allows component 2.4-62 to act 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 operation of device 2.4-10, control circuitry 2.4-12 may take action based on the measured ambient light intensity and color. As an example, the white point of a display or image sensor may be adjusted based on the measured ambient light color, or other display or image sensor color adjustments may be performed. The intensity of the display may be adjusted based on light intensity. For example, the brightness of display 2.4-14F may be increased under bright ambient light conditions to enhance the visibility of the image on the display, and the brightness of display 2.4-14F may be decreased under dim lighting conditions to save power. Image sensor operation and / or light source operation can also be adjusted based on ambient light readings.

[1073] The optical components in the effective 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 movement of device 2.4-10. Components 2.4-80 and 2.4-64 may be visible light cameras (and / or cameras sensitive to visible and infrared wavelengths) and may be combined with an inertial measurement unit to form a visual inertial ranging (VIO) system.

[1074] 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. These cameras (sometimes referred to as scene cameras or pass-through video cameras) capture moving images when the user's eye is within the eye-fitting zone 2.4-24 at the rear of device 2.4-10, and these moving images are displayed in real-time on display 2.4-14R for the user's viewing. By displaying pass-through images (pass-through video) to the user in this manner, real-time information about the user's surrounding environment is provided. If desired, 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, in which components 2.4-78 and 2.4-66 are turned off, and only movie content, game content, and / or other virtual content that does not contain real-time real-world images are provided to the user.

[1075] The input-output device 2.4-12 of device 2.4-10 can acquire user input for controlling the operation of device 2.4-10. As an example, the microphone in device 2.4-10 can acquire voice commands. Buttons, touch sensors, force sensors, and other input devices can acquire user input from the user's fingers or other external objects touching device 2.4-10. In some configurations, it may be desirable to monitor the user's hand gestures or other user body part movements. This allows the user's hand position or other body part position to be replicated in games or other virtual environments, and allows the user's hand movements to act as hand gestures (air gestures) for controlling the operation of device 2.4-10. Cameras operating in visible and infrared wavelengths, such as tracking cameras (e.g., optical components 2.4-76 and 2.4-68), can be used to capture user input such as hand gesture input. Tracking cameras such as these can also track references and other identifiable features on these controllers and other external accessories (attached device 2.4-10 of system 2.4-8) during the use of controllers to control the operation of device 2.4-10. If needed, a tracking camera can help determine the position and orientation of a handheld or wearable controller, which senses its position and orientation by measuring the magnetic field generated by coil 2.4-54. Therefore, the use of a tracking camera can help track hand movements and controller movements used to move pointers and other virtual objects displayed to the user, and can otherwise assist in the operation of device 2.4-10.

[1076] The tracking camera can operate satisfactorily in the presence of sufficient ambient light (e.g., bright visible ambient light conditions). In dim environments, supplementary light sources such as supplementary infrared light sources (e.g., optics 2.4-82 and 2.4-84) can provide supplementary illumination. Each infrared light source may include one or more light-emitting devices (light-emitting diodes or lasers) and may be configured to provide a fixed and / or controllable infrared beam that serves as supplementary illumination for the tracking camera. The infrared light sources can be turned off under bright ambient light conditions if needed and can be turned on in response to the detection of dim ambient light (e.g., using the ambient light sensing capability of optics 2.4-62).

[1077] The three-dimensional sensors in device 2.4-10 can be used to perform biometric identification operations (e.g., facial identification for authentication), to determine the three-dimensional shape of objects in a user's environment (e.g., mapping the user's environment so that a matching virtual environment can be created for the user), and / or to otherwise acquire three-dimensional content during operation of device 2.4-10. As an example, optics 2.4-74 and 2.4-70 can be three-dimensional structured light image sensors. Each three-dimensional structured light image sensor may have one or more light sources that provide structured light (e.g., a dot projector that projects an infrared dot array onto the environment, a structured light source that generates a line grid, or other structured light components that emit structured light). Each three-dimensional structured light image sensor may also include a flood illuminator (e.g., a light-emitting diode or laser that emits a wide infrared beam). Using flood illumination and structured light illumination, optics 2.4-74 and 2.4-70 can capture facial images, images of objects in the environment surrounding device 2.4-10, etc.

[1078] Optical component 2.4-72 can be an infrared three-dimensional time-of-flight camera that uses time-of-flight measurements of the emitted light to acquire three-dimensional images of objects in the environment surrounding device 2.4-10. Component 2.4-72 can have a longer range and a narrower field of view compared to the three-dimensional structured light cameras of optical components 2.4-74 and 2.4-70. The operating range of component 2.4-72 can be 30cm to 7m, 2.4-60cm to 6m, 70cm to 5m, or other suitable operating ranges (as examples).

[1079] 2.5: Systems with a covering layer sealing structure

[1080] Head-mounted devices may include a head-mounted support structure that allows the device to be worn on a 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-facing display that presents images to an eye-fitting area at the rear of the head-mounted support structure. The display may also include a forward-facing display. The forward-facing display may be mounted to the front of the head-mounted support structure and may be viewed by the user when the head-mounted device is not worn on the user's head. A forward-facing display, sometimes referred to as a public-viewable display, may also be viewable by others near the head-mounted device.

[1081] Optical components, such as image sensors and other light sensors, can be housed within the head-mounted device. In an exemplary configuration, the optical components are mounted beneath the peripheral portion of a display cover that protects the forward-facing display. The display cover or other layers within the head-mounted device can be formed of easily breakable materials such as glass. Because the head-mounted device is close to the user's eyes during operation, it may be desirable to reduce the likelihood of these layers breaking and entering the user's eyes. Therefore, laminates, such as plastic laminates, can be formed on the top and bottom surfaces of the cover. To protect the edges of the cover, an encapsulating material can be coupled to the edge surfaces, or the head-mounted device housing structure can be modified to reduce the likelihood of glass detaching from the cover.

[1082] Figure 2.5-1 This is a side view of an illustrative head-mounted electronic device. (Example:) Figure 2.5-1 As shown, 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 separating internal regions of the device 2.5-10, such as internal region 2.5-42, from external regions surrounding the device 2.5-10, such as 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, etc.) may be mounted on printed circuitry and / or other structures within the device 2.5-10 (e.g., in internal region 2.5-42).

[1083] To present an image to a user for viewing from an eye-friendly zone, such as eye-friendly zone 2.5-34, device 2.5-10 may include a rear display, such as display 2.5-14R, which may have an associated lens for focusing the image for viewing in the eye-friendly zone. These components may be mounted in an optical module (e.g., a lens barrel) to form 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 a left lens in the left eye-friendly zone and a right rear display for presenting an image to the user's right eye in the right eye-friendly zone. When structure 2.5-26 rests against the outer surface of the user's face, the user's eyes are located in eye-friendly zone 2.5-34 at the rear R of device 2.5-10.

[1084] Support structure 2.5-26 may include a main support structure (sometimes referred to as the main part or shell). The main shell support structure may extend from the front side F of device 2.5-10 to the opposite rear side R of device 2.5-10. On the rear side R, support structure 2.5-26 may have a padded structure to enhance user comfort when support structure 2.5-26 rests against the user's face. If desired, support structure 2.5-26 may include an optional head strap and / or other structures that allow device 2.5-10 to be worn on the user's head.

[1085] Device 2.5-10 may have a publicly viewable front display, such as display 2.5-14F mounted on the front side F of support structure 2.5-26. Display 2.5-14F may be viewable by the user when the user is not wearing device 2.5-10, and / or may be viewable by others near device 2.5-10. As an example, display 2.5-14F may be visible on the front side F of device 2.5-10 to an external viewer who is viewing device 2.5-10 from the front side F.

[1086] Figure 2.5-2 The diagram illustrates an exemplary system that may include a head-mounted device. Figure 2.5-2 As shown, system 2.5-8 may have one or more electronic devices 2.5-10. Device 2.5-10 may include a head-mounted device (e.g., Figure 2.5-1 Devices 2.5-10), accessories such as controllers and headsets, computing devices (e.g., cellular phones, tablet computers, laptop computers, desktop computers and / or telecomputing devices that supply content to head-mounted devices) and / or other devices that communicate with each other.

[1087] Each electronic device 2.5-10 may have control circuitry 2.5-12. Control circuitry 2.5-12 may include storage and processing circuitry for controlling the operation of device 2.5-10. Circuitry 2.5-12 may include storage devices such as hard disk drive storage devices, non-volatile memory (e.g., electrically programmable read-only memory configured to form a solid-state drive), volatile memory (e.g., static or dynamic random access memory), etc. The processing circuitry in control circuitry 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 (ASICs), and other integrated circuits. Software code may be stored on the storage devices in circuitry 2.5-12 and run on the processing circuitry in circuitry 2.5-12 to implement control operations for device 2.5-10 (e.g., data acquisition operations, operations involving adjusting components of device 2.5-10 using control signals, etc.). Control circuitry 2.5-12 may include wired and wireless communication circuitry. For example, control circuitry 2.5-12 may include radio frequency transceiver circuitry, such as cellular telephone transceiver circuitry, wireless local area network transceiver circuitry (e.g., Circuits), millimeter-wave transceiver circuits and / or other wireless communication circuits.

[1088] During operation, the communication circuitry of the devices in system 2.5-8 (e.g., the communication circuitry of control circuitry 2.5-12 in device 2.5-10) can be used to support communication between electronic devices. For example, one electronic device can transmit video data, audio data, control signals, and / or other data to another electronic device in system 2.5-8. The electronic devices in system 2.5-8 can use wired and / or wireless communication circuitry to communicate over one or more communication networks (e.g., the Internet, a local area network, etc.). The communication circuitry can be used to allow device 2.5-10 to receive data from and / or provide data to external equipment (e.g., a network-shared computer, portable devices such as handheld devices or laptops, online computing equipment such as a remote server or other remote computing equipment, or other electrical equipment).

[1089] 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 allow a user to provide user input to the device 2.5-10. The input-output device 2.5-22 can also be used to acquire information about the environment in which the device 2.5-10 operates. Output components in device 2.5-22 allow the device 2.5-10 to provide output to the user and can be used to communicate with external electrical equipment.

[1090] like Figure 2.5-2 As shown, 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... Figure 2.5-1 The display 2.5-14R. Device 2.5-10 may include, for example: left and right components such as left and right scanning mirror display devices or other image projectors, silicon-based liquid crystal display devices, digital mirror devices or other reflective display devices; a left and right display panel based on a light-emitting diode pixel array (e.g., a thin-film organic light-emitting display having a polymer or semiconductor substrate such as a silicon substrate, or a display device based on a pixel array formed from a crystalline semiconductor light-emitting diode die); a liquid crystal display panel; and / or other left and right display devices that respectively provide images to the left and right eye-adaptive areas for viewing by the user's left and right eyes. Display components such as these components (e.g., a thin-film organic light-emitting display having a flexible polymer substrate or a display based on a pixel array formed from a crystalline semiconductor light-emitting diode die on a flexible substrate) can also be used to form the front-facing display of device 2.5-10, such as... Figure 2.5-1 A front-facing display 2.5-14F (sometimes referred to as a front-viewing display, front monitor, or public-viewable display).

[1091] During operation, displays 2.5-14 (e.g., displays 2.5-14R and / or 2.5-14F) can be used to display visual content (e.g., still and / or moving images, text, graphics, movies, games, and / or other visual content, including pictures from camera sensors and pass-through video) to the user of device 2.5-10. 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 circuitry 2.5-12. This virtual content may sometimes be referred to as computer-generated content. Computer-generated content may be displayed in the absence of real-world content, or may be combined with real-world content. In some configurations, real-world images may be captured by a camera (e.g., a forward-facing camera, sometimes referred to as a front-facing camera), and computer-generated content may be electronically overlaid on portions of the real-world image (e.g., when device 2.5-10 is a virtual reality headset).

[1092] Input-output circuitry 2.5-22 may include sensors 2.5-16. Sensors 2.5-16 may include, for example, 3D sensors (e.g., 3D image sensors, such as structured light sensors that emit light beams and use 2D digital image sensors to acquire image data for 3D images from points or other light spots generated when these beams illuminate a target, binocular 3D image sensors that use two or more cameras in a binocular imaging arrangement to acquire 3D images, 3D LIDAR (light detection and ranging) sensors (sometimes referred to as time-of-flight cameras or 3D time-of-flight cameras), 3D radio frequency sensors, or other sensors that acquire 3D image data), cameras (e.g., 2D infrared and / or visible digital image sensors), gaze tracking sensors (e.g., gaze tracking systems based on image sensors and, if necessary, also based on light sources emitting one or more light beams, which, after reflection from the user's eyes, are used to acquire image data for 3D images), cameras (e.g., 2D infrared and / or visible digital image sensors), and gaze tracking sensors (e.g., gaze tracking systems based on image sensors and, if necessary, ...). Sensors such as those used for tracking, 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, flashing sensors that acquire time information about the presence of ambient light conditions such as time-varying ambient light intensity associated with artificial lighting, microphones for acquiring voice commands and other audio inputs, sensors configured to acquire information about motion, positioning and / or orientation (e.g., accelerometers, gyroscopes, compasses and / or inertial measurement units including all of these sensors or a subset of one or two of these sensors), and / or other sensors.

[1093] Sensors and other input devices in the input-output devices 2.5-22 can be used to acquire user input and other information. If desired, the input-output devices 2.5-22 may include other devices 2.5-24, such as haptic output devices (e.g., vibrating components), light-emitting diodes, lasers and other light sources (e.g., light-emitting devices that emit light to illuminate the environment around the devices 2.5-10 when ambient light levels are low), speakers such as earphones for generating audio output, circuitry for receiving wireless power, circuitry for wirelessly transmitting power to other devices, batteries and other energy storage devices (e.g., capacitors), joysticks, buttons and / or other components.

[1094] Such as combination Figure 2.5-1 The electronic device 2.5-10 may have a head-mounted support structure such as a head-mounted support structure 2.5-26 (e.g., a head-mounted housing structure such as a housing wall, strap, etc.). The head-mounted support structure may be configured to be worn on the user's head during operation of the device 2.5-10 (e.g., against the user's face, thereby covering the user's eyes), and may support the display 2.5-14, sensors 2.5-16, other components 2.5-24, other input-output devices 2.5-22, and control circuitry 2.5-12 (see, for example...). Figure 2.5-1 The components 2.5-40 and displays 2.5-14R and 2.5-14F, which may include associated optical modules.

[1095] Figure 2.5-3 This is a front view of device 2.5-10 in an exemplary configuration, where device 2.5-10 has a common viewable display such as a front-facing display 2.5-14F. Figure 2.5-3 As shown, the support structure 2.5-26 of the device 2.5-10 may have a right portion and a left portion on either side of the bridge of the nose 2.5-90. The bridge of the nose 2.5-90 may be a curved outer surface configured to receive and rest on the user's nose to help support the support housing 2.5-26 on the user's head.

[1096] The display 2.5-14F may have active areas configured to display images, such as an active area AA, and inactive areas IA for not displaying images. The active area AA may be rectangular, a rectangle with rounded corners, may have teardrop-shaped portions on the left and right sides of the device 2.5-10, may have a shape with straight edges, a shape with curved edges, a shape with peripheral edges having both straight and curved portions, and / or other suitable shapes. Figure 2.5-3As shown, the effective area AA may have a curved recessed portion at 2.5-90 degrees along the bridge of the nose. The presence of the nose-shaped recess in the effective area AA helps to fit the effective area AA within the available space of the housing at 2.5-26 degrees without unduly restricting the size of the effective area AA.

[1097] The effective area AA comprises a pixel array. Pixels can be, for example, light-emitting diode pixels formed on a flexible display panel substrate using thin-film organic light-emitting diodes or crystalline semiconductor light-emitting diode dies (sometimes referred to as micro-light-emitting diodes). If desired, configurations in which displays 2.5-14F utilize other display technologies may also be used. In this document, exemplary arrangements in which displays 2.5-14F are formed of light-emitting diode displays, such as organic light-emitting diode displays formed on a flexible substrate (e.g., a substrate formed from a bendable polyimide layer or other flexible polymer sheet), are sometimes described as examples. The pixels of the effective area AA may be formed on a display device such as a display panel (e.g., a flexible organic light-emitting diode display panel). In some configurations, the shape of the effective area AA may have a peripheral edge comprising straight segments or a combination of straight and curved segments. Configurations in which the entire shape of the effective area AA is characterized by curved peripheral edges may also be used.

[1098] The 2.5-14F display may have invalid areas, such as invalid area IA, that do not contain pixels and do not display images. Invalid area IA may form an invalid boundary area extending along one or more portions of the peripheral edge of the valid area AA. Figure 2.5-3 In an exemplary configuration, the invalid region IA has an annular shape surrounding the valid region AA and forming an invalid boundary. In this type of arrangement, the width of the invalid region IA can be relatively constant, and the inner and outer edges of the region IA can be characterized by straight and / or curved segments, or can be curved along the entire length of the edge. For example, the outer edge of the region IA (e.g., the periphery of the display 2.5-14F) can have a curved profile extending parallel to the curved edge of the valid region AA.

[1099] In some configurations, device 2.5-10 may operate in conjunction with other devices in system 2.5-8, such as wireless controllers and other accessories. These accessories may have magnetic sensors that sense the direction and intensity of a magnetic field. Device 2.5-10 may have one or more electromagnets configured to emit a magnetic field. The magnetic field may be measured by wireless accessories near device 2.5-10, allowing the accessories to determine their orientation and location relative to device 2.5-10. This allows the accessories to wirelessly provide device 2.5-10 with real-time information about their current location, orientation, and movement, enabling the accessories to act as wireless controllers. Accessories may include wearable devices, handheld devices, and other input devices.

[1100] In an exemplary configuration, device 2.5-10 may have a coil extending around the periphery of display 2.5-14F (e.g., along the periphery of active region AA below inactive region IA). The coil may have any suitable number of turns (e.g., 1-10, at least 2, at least 5, at least 10, 10-50, less than 100, less than 25, less than 6, etc.). These turns may be formed on a substrate by metal traces, by wires, and / or by other conductive lines. During operation, control circuitry 2.5-12 may supply an alternating current (AC) drive signal to the coil. The drive signal may have a frequency of 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 (as an example). When AC current flows through the coil, a corresponding magnetic field is generated near device 2.5-10. Electronic devices located near device 2.5-10, such as wireless controllers with magnetic sensors, can use the magnetic field as a reference, allowing the wireless controllers to determine their orientation, positioning, and / or movement relative to device 2.5-10 to provide input to device 2.5-10 as they move.

[1101] As an example, consider a handheld wireless controller used to control the operation of device 2.5-10. During operation, device 2.5-10 uses a coil to emit a magnetic field. When the handheld wireless controller is moved, the controller's magnetic sensor can monitor the controller's position and movement relative to device 2.5-10 by monitoring the strength, orientation, and changes in strength and / or orientation of the magnetic field emitted by the coil as the user moves the controller through the air. An electronic device can then wirelessly transmit information about the controller's position and orientation to device 2.5-10. In this way, a user can manipulate the handheld controller, wearable controller, or other external accessories to provide air gestures, pointing inputs, manipulation inputs, and / or other user inputs to device 2.5-10.

[1102] Devices 2.5-10 may have optical components (e.g., Figure 2.5-2The components of the optical sensor in sensor 2.5-16 are included. These components can be mounted in any suitable location on the head-mounted support structure 2.5-26 (e.g., on the head strap, on the housing 2.5-26, etc.). The optical components and other components can face rearward (e.g., when mounted on the back of device 2.5-10), face sideways (e.g., to the left or right), face downward or upward, face the front of device 2.5-10 (e.g., when mounted on the front of device 2.5-10), can be mounted in any combination of these directions (e.g., forward, right, and downward) and / or can be mounted in other suitable orientations. In an exemplary configuration, at least some of the components of device 2.5-10 are mounted outward and forward (and optionally facing sideways and / or upward and downward). For example, the forward-facing cameras for pass-through video can be configured to be mounted on the left and right sides of the front of the device 2.5-10, in which the cameras are slightly diverged along the horizontal dimension, such that the fields of view of these cameras overlap to some extent when capturing a wide-angle image of the environment in front of the device 2.5-10. If desired, the captured image may include portions of the user's surrounding environment below, above, and to the sides of the area directly in front of the device 2.5-10.

[1103] To help conceal components such as optical elements from being seen from the outside of the device 2.5-10, it may be desirable to utilize an aesthetically pleasing overlay structure to cover some or all of these components. The overlay structure may include transparent portions (e.g., windows for optical elements) characterized by sufficient optical transparency to allow the overlapping optical elements to operate satisfactorily. For example, an ambient light sensor may be covered with a layer that appears opaque to an external viewer to help conceal the sensor from view, but allows sufficient ambient light to pass through to enable satisfactory ambient light measurements. As another example, optical elements emitting infrared light may be overlapped with a visually opaque material that is transparent to infrared light.

[1104] In the exemplary configuration, the optical components of device 2.5-10 can be mounted on... Figure 2.5-3In the invalid region IA, the aesthetic overlay structure can be formed as an annular shape overlapping the optical components in the invalid region IA. The aesthetic overlay structure can be formed from ink, polymer structures, including metals, glass, other materials, and / or combinations of these materials. In an exemplary configuration, the aesthetic overlay structure can be formed from an annular member having an area matching the occupied area of ​​the invalid region IA. For example, if the valid region AA includes a left and right portion having a teardrop shape, the annular member can have a curved edge following the curved periphery of the teardrop-shaped portion of the valid region AA. The annular member can be formed from one or more polymer structures (e.g., the annular member can be formed from a polymer ring). Because the annular member helps to conceal the overlapping components so that they are not visible, the annular member is sometimes referred to as a shield or annular shield member. The appearance of the shield or other aesthetic overlay structure can be characterized by neutral colors (white, black, or gray) or non-neutral colors (e.g., blue, red, green, gold, rose gold, etc.).

[1105] If required, the 2.5-14F display may have a protective display overlay. The overlay may overlap with the active area AA and the inactive area IA (e.g., in the area from...). Figure 2.5-1 The entire front surface of the F-viewing device 2.5-10 may be covered by a cover layer. The cover layer, sometimes referred to as the shell wall or transparent shell wall, may have a rectangular shape, a shape with teardrop-shaped portions, an oval shape, or other shapes with curved and / or straight edges.

[1106] The cover layer can be formed from transparent materials such as glass, polymers, transparent crystalline materials such as sapphire, light-transmitting ceramics, other transparent materials, and / or combinations of these materials. As an example, the protective display cover layer for a display 2.5-14F can be formed from safety glass (e.g., laminated glass comprising a light-transmitting glass layer and a laminated polymer film). Optional coatings can be applied to the surface of the display cover layer. If desired, the display cover layer can be chemically strengthened (e.g., using an ion-exchange process to produce a scratch-resistant outer material layer under compressive stress). In some configurations, the display cover layer can 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 rigid polymer layer coupled to a glass layer or another rigid polymer layer, etc.) to enhance the performance of the cover layer.

[1107] In the effective area AA, the display overlay may overlap with the pixels of the display panel 2.5-14P. The display overlay in the effective area AA is preferably transparent to allow viewing of the image presented on the display panel 2.5-14P. In the ineffective area IA, the display overlay may overlap with a ring-shaped shield or other aesthetically pleasing covering structure. The shield and / or other covering structure (e.g., an opaque ink coating on the inner surface of the display overlay and / or structure) may be sufficiently opaque to help conceal some or all of the optical components in the ineffective area IA from being seen. Windows may be provided in the shield or other aesthetically pleasing covering structure to help ensure satisfactory operation of the optical components overlapped by these structures. Windows may be formed by apertures, by areas of the shield or other aesthetically pleasing covering structure that have been locally thinned to enhance light transmittance, by window members with desired light transmittance properties already inserted into mating openings in the shield, and / or by other shield window structures.

[1108] exist Figure 2.5-3 In the example, device 2.5-10 includes optical components, such as optical components 2.5-60, 2.5-62, 2.5-64, 2.5-66, 2.5-68, 2.5-70, 2.5-72, 2.5-74, 2.5-76, 2.5-78, and 2.5-80 (as examples). These optical components (e.g., from...) Figure 2.5-2 Each optical component in the sensors selected in 2.5-16 (optical sensors, light-emitting devices, etc.) can be configured to detect light and, if necessary, to emit light (e.g., ultraviolet, visible, and / or infrared light).

[1109] In an exemplary configuration, optical component 2.5-60 can sense ambient light (e.g., visible ambient light). Specifically, optical component 2.5-60 may have a photodetector that senses changes in ambient light intensity over time. As an example, if a 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., 60 Hz AC mains). The photodetector of component 2.5-60 can sense the artificial light from the artificial light source, characterized by intensity fluctuations at 60 Hz. Control circuitry 2.5-12 can use this information to adjust clocks or other timing signals associated with the operation of the image sensor in device 2.5-10 to help avoid unwanted interference between the light source frequency and the frame rate or other frequencies associated with image capture operation. Control circuitry 2.5-12 can also use measurements from component 2.5-60 to help identify the presence and type of artificial light. In this way, control circuitry 2.5-12 can detect the presence of light such as fluorescence or other light with known non-ideal color characteristics, and can compensate for color shifts (e.g., white point adjustment) in color-sensitive components such as cameras and displays. Because optical component 2.5-60 measures fluctuations in light intensity, component 2.5-60 is sometimes referred to as a flicker sensor or ambient light frequency sensor.

[1110] Optical component 2.5-62 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 monochromatic sensor that measures the intensity of ambient light. In a multi-photodetector configuration, each photodetector may be composed of overlapping optical filters that allow different wavelength bands (e.g., different visible and / or infrared passbands) to pass through. The optical filter passbands may overlap at their edges. This allows component 2.5-62 to act 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 operation of device 2.5-10, control circuitry 2.5-12 may take action based on the measured ambient light intensity and color. As an example, the white point of a display or image sensor may be adjusted based on the measured ambient li...
