An extension piece is coupled to the hinge and the temple, and the extension piece extends relative to the hinge to allow the temple to super-extend relative to the frame. When the temple rotates around the hinge, a first auxiliary loop allows the FPC to extend, and a second auxiliary loop allows the temple to extend radially outward from the hinge. The hinge is coupled to the frame, and a portion of the temple coupled to the frame or forming a part of the frame can be inserted between the frame and the hinge. The extension piece may form a part of the hinge. The extension piece may include a bushing and a spring to allow the temple to super-extend.

[0034] The following description will partially set forth other objects, advantages, and novel features of the examples. Such other objects, advantages, and novel features will be apparent to those skilled in the art after reviewing the following and accompanying drawings, or may be learned by making or operating the examples. The objects and advantages of the subject matter may be realized and obtained by the methods, means, and combinations particularly pointed out in the appended claims.

[0035] The following detailed description sets forth numerous specific details by way of example in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the teachings may be practiced without such details. In other cases, in order to avoid unnecessarily obscuring various aspects of the teachings, well-known methods, processes, components, and circuits are described at a relatively high level without detailed description.

[0036] As used herein, the term "coupled" refers to any logical, optical, physical or electrical connection, link, etc., by which a signal or light generated or provided by one system element is transmitted to another coupled element. Unless otherwise specified, coupled elements or devices are not necessarily directly connected to each other and may be separated by intermediate components, elements or communication media that may modify, manipulate or carry the light or signals.

[0037] The orientation of the eye-mounted device, related components, and any set of equipment incorporating an eye scanner and camera shown in any of the figures is by way of example only and is used for purposes of illustration and discussion. In operation of a particular variable optical processing application, the eye-mounted device may be oriented in any other orientation suitable for the particular application of the eye-mounted device, such as up, down, sideways, or any other orientation. Furthermore, for the purposes of the scope used herein, any directional terms, such as front, back, inward, outward, toward, left, right, lateral, longitudinal, up, down, high, low, top, bottom, and side, are used by way of example only and do not limit the orientation or orientation of any optical device or optical device component configured as described herein.

[0038] Reference will now be made in detail to the examples illustrated in the accompanying drawings and discussed below.

[0039] Figure 1A FIG. 1 is a side view of an exemplary hardware configuration of the eye-mounted device 100, which includes a right optical assembly 180B ( Figure 2A The eye-mounted device 100 includes a plurality of visible light cameras 114A-B ( Figure 7 ), wherein the right visible light camera 114B is located on the right temple 110B.

[0040] The left and right visible light cameras 114A-B are equipped with image sensors that are sensitive to wavelengths in the visible light range. Each visible light camera 114A-B has a different coverage angle facing forward, for example, visible light camera 114B has a coverage angle 111B as shown. The coverage angle is the angular range over which the image sensors of visible light cameras 114A-B pick up electromagnetic radiation and generate an image. Examples of such visible light cameras 114A-B include high-resolution complementary metal oxide semiconductor (CMOS) image sensors and video graphics array (VGA) cameras, such as 640p (e.g., 640×480 pixels, a total of 0.3 megapixels), 720p, or 1080p. Image sensor data from visible light cameras 114A-B is captured along with geolocation data, digitized by an image processor, and then stored in memory.

[0041] To present stereoscopic vision, visible light cameras 114A-B may be coupled to an image processor (element 912 shown in FIG. 9 ) for digital processing and time stamping of scene images. Image processor 912 includes circuitry for receiving signals from visible light cameras 114A-B and processing the signals from visible light cameras 114A-B into a format suitable for storage in a memory (element 934 in FIG. 9 ). Timestamps may be added by image processor 912 or other processors controlling the operation of visible light cameras 114A-B. Visible light cameras 114A-B support stereo cameras to simulate human binocular vision. The stereo camera has a function of generating a time stamp based on two captured images ( Figure 7 Components 758A-B) to reproduce a three-dimensional image ( Figure 7 Such three-dimensional images 715 provide, for example, an immersive and realistic experience for virtual reality or video games. For stereoscopic vision, image pairs 758A-B are generated at a given moment, one for each of the left and right visible light cameras 114A-B. When the image pairs 758A-B generated from the front-facing coverage angles 111A-B of the left and right visible light cameras 114A-B are stitched together (e.g., by image processor 912), optical components 180A-B can provide depth perception.

[0042] In one example, the user interface field of view adjustment system includes an eyewear device 100. The eyewear device 100 includes a frame 105, a right temple 110B extending from a right side 170B of the frame 105, and a perspective image display 180D (with an optical component 180B) for presenting a graphical user interface to a user. Figure 2A-B). The eye-mounted device 100 includes a left visible light camera 114A connected to the frame 105 or the left temple 110A, for capturing a first image of a scene. The eye-mounted device 100 also includes a right visible light camera 114B connected to the frame 105 or the right temple 110B, for capturing a second image of the scene that partially overlaps with the first image (e.g., simultaneously with the left visible light camera 114A). Figure 1A -B, but the user interface field of view adjustment system also includes a processor 932 coupled to the eye-mounted device 100 and connected to the visible light cameras 114A-B, a memory 934 accessible to the processor 932, and programming in the memory 934, as shown in the eye-mounted device 100 itself or another part of the user interface field of view adjustment system.

[0043] Although in Figure 1A , but the eye-mounted device 100 also includes a head motion tracker ( Figure 1B 109) or an eye movement tracker ( Figure 2B Element 213 in FIG. 9 ). The eye-mounted device 100 also includes a see-through image display 180C-D of the optical assembly 180A-B for presenting a series of display images, and an image display driver (element 942 in FIG. 9 ) coupled to the see-through image display 180C-D of the optical assembly 180A-B to control the image display 180C-D of the optical assembly 180A-B to present a series of display images 715, which will be described in further detail below. The eye-mounted device 100 also includes a memory 934 and a processor 932 capable of accessing the image display driver 942 and the memory 934. The eye-mounted device 100 also includes programming in the memory (element 934 in FIG. 9 ). The processor 932 executes the programming to configure the eye-mounted device 100 to perform functions, including the function of presenting an initial display image of the sequence of display images through the see-through image display 180C-D, the initial display image having an initial field of view corresponding to an initial head direction or an initial eye gaze direction ( Figure 5 Element 230 in).

[0044] The processor 932 may also be programmed to configure the eye-mounted device 100 to detect the movement of the eye-mounted device user by: (i) detecting the movement of the eye-mounted device user via a head motion tracker ( Figure 1B 109) to track the user's head movement, or (ii) via an eye movement tracker ( Figure 2B and Figure 5213 in the eye-mounted device 100) tracks eye movements of a user of the eye-mounted device 100. The eye-mounted device 100 may also be configured to determine a field of view adjustment for an initial field of view of an initial display image based on the detected user movement by the processor 932. The field of view adjustment includes a continuous field of view corresponding to a continuous head direction or a continuous eye direction. The eye-mounted device 100 may be further configured to generate a continuous display image of a display image sequence based on the field of view adjustment by the processor 932. The eye-mounted device 100 may be further configured to present the continuous display image through the perspective image display 180C-D of the optical assembly 180A-B by the processor 932.

[0045] Figure 1B yes Figure 1A FIG. 1 is a top cross-sectional view of the temple of the eye-mounted device 100, showing the right visible light camera 114B, the head motion tracker 109, and the circuit board. The configuration and mounting position of the left visible light camera 114A are substantially similar to those of the right visible light camera 114B, except that it is connected and coupled to the left side 170A. As shown, the eye-mounted device 100 includes the right visible light camera 114B and the circuit board, which may be a flexible printed circuit board (PCB) 140. The right hinge 226B connects the right temple 110B to the right temple 125B of the eye-mounted device 100. In some examples, the components of the right visible light camera 114B, the flexible printed circuit board 140, or other electrical connectors or contacts may be located on the right temple 125B or the right hinge 226B.

[0046] As shown, the eye-mounted device 100 is equipped with a head motion tracker 109, which includes an inertial measurement unit (IMU) and the like. An inertial measurement unit is an electronic device that uses a combination of accelerometers and gyroscopes, and sometimes a magnetometer, to measure and report the body's specific force, angular velocity, and sometimes the magnetic field around the body. The working principle of the inertial measurement unit is to detect linear acceleration using one or more accelerometers and rotation rate using one or more gyroscopes. The typical configuration of an inertial measurement unit is: three axes, each equipped with an accelerometer, gyroscope, and magnetometer: horizontal axis for left and right movement (X), vertical axis (Y), for up and down movement, depth or distance axis, for up and down movement (Z). The accelerometer detects the gravity vector. The magnetometer defines the rotation in the magnetic field (for example, facing south, north, etc.), and its role is similar to a compass that generates a heading reference value. The three accelerometers are used to detect acceleration along the horizontal, vertical, and depth axes defined above, which can be defined relative to the ground, the eye-mounted device 100, or the user wearing the eye-mounted device 100.

[0047] The eye-mounted device 100 detects movement of a user of the eye-mounted device 100 by tracking the user's head movement via the head movement tracker 109. The head movement includes a change in the head direction along a horizontal axis, a vertical axis, or a combination thereof relative to an initial head direction during presentation of an initial display image on the image display. In an example, tracking the head movement of the user's head via the head movement tracker 109 includes measuring the initial head direction along a horizontal axis (e.g., an X-axis), a vertical axis (e.g., a Y-axis), or a combination thereof (e.g., lateral or diagonal movement) via the inertial measurement unit 109. Tracking the head movement of the user's head via the head movement tracker 109 also includes measuring continuous head directions along a horizontal axis, a vertical axis, or a combination thereof via the inertial measurement unit 109 during presentation of the initial display image.

[0048] Tracking the head movement of the user's head via the head movement tracker 109 also includes determining a change in the head direction based on the initial head direction and the subsequent head direction. Detecting the user movement of the eye-mounted device 100 also includes determining, in response to tracking the user's head movement via the head movement tracker 109, that the change in the head direction exceeds a deviation angle threshold along the horizontal axis, the vertical axis, or a combination thereof. The deviation angle threshold is between about 3° and 10°. As used herein, the term "about" when referring to an angle means ±10% of the amount.

[0049] Changes along the horizontal axis slide three-dimensional objects such as characters, bitmaps, application icons, etc. into and out of view by, for example, hiding, unhiding, or otherwise adjusting the visibility of the three-dimensional objects. For example, in one example, when the user looks up, changes along the vertical axis display weather information, time of day, date, calendar appointments, etc. In another example, when the user looks down along the vertical axis, the eye-mounted device 100 can be powered off.

[0050] The right temple 110B includes a temple body 211 and a temple cap. Figure 1B The temple cap is omitted in the cross-section shown. The right temple 110B is internally arranged with various interconnected circuit boards, such as a printed circuit board or a flexible printed circuit board, which includes a right visible light camera 114B, a microphone 130, a speaker 132, a low-power wireless circuit (e.g., for communicating via Bluetooth TM wireless short-range network communications), high-speed wireless circuits (for example, controller circuits for wireless local area network communications via WiFi).

[0051] The right visible light camera 114B is coupled to or disposed on the flexible printed circuit board 240 and is covered by a visible light camera cover lens that is focused through an opening formed in the right temple 110B. In some examples, the frame 105 connected to the right temple 110B includes an opening for the visible light camera cover lens. The frame 105 includes a side facing forward, and the side configuration ensures that it faces outward away from the user's eyes. The visible light camera cover lens opening is formed on the forward side and passes through the forward side. In this example, the right visible light camera 114B forms an outward coverage angle 111B with the right eye line of sight or viewing angle of the user of the eye-mounted device 100. The visible light camera cover lens can also be adhered to the outwardly facing surface of the right temple 110B, wherein the outwardly facing coverage angles along different outward directions constitute an opening. Indirect coupling via an intermediate component can also be used.

[0052] The left (first) visible light camera 114A is connected to the left perspective image display 180C of the left optical assembly 180A to generate a first background scene of the first continuous display image. The right (second) visible light camera 114B is connected to the right perspective image display 180D of the right optical assembly 180B to generate a second background scene of the second continuous display image. The first background scene and the second background scene partially overlap to present a three-dimensional observable area of ​​the continuous display image.

[0053] The flexible printed circuit board 140 is disposed in the right temple 110B and is coupled to one or more other components disposed in the right temple 110B. Although the right visible light camera 114B is shown as being formed on a circuit board of the right temple 110B, it may also be formed on a circuit board of the left temple 110A, temples 125A-B, or frame 105.

[0054] Figure 2A 1 is a rear view of an example hardware configuration of an eye-mounted device 100, which includes an eye scanner 113 on a frame 105 for use by a system for determining the eye position and gaze direction of a wearer / user of the eye-mounted device 100. Figure 2A As shown, the eye-mounted device 100 is in a form that ensures that it can be configured to be worn by a user. Figure 2A The eye-mounted device 100 may take other forms and may be combined with other types of frames, such as headgear, headphones, or helmets.

[0055] In the glasses example, the eyewear device 100 includes a frame 105, which includes a right frame 107B and a left frame 107A, and the right frame 107B is connected to the left frame 107A through a nose bridge 106 adapted to the user's nose. The left and right frames 107A-B are each equipped with openings 175A-B, which are used to fix respective optical elements 180A-B, such as lenses and perspective displays 180C-D. As used herein, the term lens refers to a transparent or translucent glass or plastic sheet that has a curved and flat surface that can converge / diverge light or converge / diverge little or no light.

[0056] Although shown as having two optical elements 180A-B, the eye-mounted device 100 may include other arrangements, such as a single optical element, depending on the application or intended user of the eye-mounted device 100. As further shown, the eye-mounted device 100 is provided with a left temple 110A proximate to the left side 170A of the frame 105 and a right temple 110B proximate to the right side 170B of the frame 105. The temples 110A-B may be integrated within the frame 105 on the respective 170A-B sides (as shown), or implemented as separate components attached to the frame 105 on the respective 170A-B sides. In addition, the temples 110A-B may also be integrated within temples (not shown) attached to the frame 105.

[0057] exist Figure 2A In the example of , the eye scanner 113 includes an infrared emitter 115 and an infrared camera 120. Visible light cameras typically include a blue light filter to block infrared light detection, and in one example, the infrared camera 120 is a visible light camera, such as a low-resolution video graphics array (VGA) camera (e.g., 640×480 pixels, a total of 0.3 megapixels) with the blue light filter removed. The infrared emitter 115 and the infrared camera 120 are jointly disposed on the frame 105, for example, both are connected to the upper portion of the left frame 107A as shown. The frame 105 or one or more left and right temples 110A-B include a circuit board (not shown), which includes the infrared emitter 115 and the infrared camera 120. For example, the infrared emitter 115 and the infrared camera 120 can be connected to the circuit board by soldering.

[0058] Other arrangements of the infrared emitter 115 and the infrared camera 120 can be implemented, including: the infrared emitter 115 and the infrared camera 120 can be arranged on the right frame 107B, or at different locations on the frame 105, for example, the infrared emitter 115 is arranged on the left frame 107A and the infrared camera 120 is arranged on the right frame 107B. In another example, the infrared emitter 115 is arranged on the frame 105 and the infrared camera 120 is arranged on one of the temples 110A-B, or vice versa. The infrared emitter 115 can be connected to substantially anywhere on the frame 105, the left temple 110A, or the right temple 110B for emitting the infrared light pattern. Similarly, the infrared camera 120 can be connected to substantially anywhere on the frame 105, the left temple 110A, or the right temple 110B for capturing at least one reflection change in the infrared light emission pattern.

[0059] The infrared emitter 115 and the infrared camera 120 are arranged to face inwardly toward the user's eyes, have a partial or full field of view of the eyes, and can identify the corresponding eye position and gaze direction. For example, the infrared emitter 115 and the infrared camera 120 are arranged directly in front of the eyes, on the upper part of the frame 105, or in the temples 110A-B at both ends of the frame 105.

[0060] Figure 2B 2 is a rear view of another example hardware configuration of the eye-mounted device 200. In this example configuration, the eye-mounted device 200 is incorporated into the eye scanner 213 located on the right temple 210B. As shown in the figure, the infrared emitter 215 and the infrared camera 220 are arranged together on the right temple 210B. It should be understood that the eye scanner 213 or one or more components of the eye scanner 213 can be arranged on the left temple 210A of the eye-mounted device 200 and other locations, such as the frame 105. The infrared emitter 215 and the infrared camera 220 are arranged together with the eye scanner 213. Figure 2A , but the eye scanner 213 may be modified to be sensitive to different wavelengths of light, as previously described in Figure 2A As described in.

[0061] and Figure 2A Similar to the figure, the eye-mounted device 200 includes a frame 105, the frame 105 includes a left frame 107A connected to a right frame 107B through a nose bridge 106; and the left and right frames 107A-B each have corresponding openings, which can be used to fix their respective optical elements 180A-B that constitute the see-through displays 180C-D.

[0062] Figure 2C -D is a rear view of an example hardware configuration of the eye-mounted device 100, including two different types of see-through image displays 180C-D. In one example, these see-through image displays 180C-D of the optical components 180A-B include integrated image displays. Figure 2C As shown, the optical assembly 180A-B includes a suitable display matrix 180C-D of any suitable type, such as a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a waveguide display, or any other such display. The optical assembly 180A-B also includes one or more optical layers 176, which may include lenses, optical coatings, prisms, reflectors, waveguides, light strips, and other optical components in any combination. The optical layer 176A-N may include a prism having a suitable size and configuration and having a first surface for receiving light from the display matrix and a second surface for emitting light to the user's eyes. The prism of the optical layer 176A-N extends along all or at least a portion of the corresponding openings 175A-B in the left and right frames 107A-B, thereby allowing the user to see the second surface of the prism when the user's eyes look through the corresponding left and right frames 107A-B. The first surfaces of the prisms of the optical layers 176A-N are arranged to face upward along the frame 105, and the display matrix covers the prisms, ensuring that photons and light emitted from the display matrix are impinged on the first surface. The size and shape of the prisms can ensure that the light is refracted within the prisms and directed to the user's eyes by the second surfaces of the prisms of the optical layers 176A-N. In this regard, the second surfaces of the prisms of the optical layers 176A-N can be convex to direct the light to the center of the eye. The size and shape of the prisms can be (optionally) configured to magnify the image projected from the see-through image display 180C-D, and the light passes through the prisms so that the image viewed from the second surface is larger in one or more dimensions than the image emitted from the see-through image display 180C-D.

[0063] In another example, the see-through image displays 180C-D of the optical assemblies 180A-B include: Figure 2D The projected image display shown. The optical assembly 180A-B includes a laser projector 150, which is a three-color laser projector using a scanning mirror or a galvanometer. During operation, a light source such as a laser projector 150 is disposed in or on one of the temples 125A-B of the eye-mounted device 100. The optical assembly 180A-B includes one or more optical strips 155A-N that are spaced apart along the width of the lens of the optical assembly 180A-B or along the depth of the lens between the front and back surfaces of the lens.

[0064] When the photons projected from the laser projector 150 pass through the lenses of the optical components 180A-B, the photons encounter the light strips 155A-N. When a particular photon encounters a particular light strip, the photon is either redirected to the user's eye or passed to the next light strip. The specific photons or light beams can be controlled by combining the laser projector 150 modulation and the light strip modulation. In one example, the processor controls the light strips 155A-N by initiating mechanical, acoustic, or electromagnetic signals. Although shown as having two optical components 180A-B, the eye-mounted device 100 may also adopt other arrangements, such as a single or three optical components, or different optical component 180A-B arrangements may be adopted depending on the application of the eye-mounted device 100 or the specific circumstances of the intended user.

[0065] like Figure 2C As further shown in Figures 1-D, the eyewear device 100 is provided with a left temple 110A adjacent to the left side 170A of the frame 105 and a right temple 110B adjacent to the right side 170B of the frame 105. The temples 110A-B can be integrated into the frame 105 on the corresponding lateral sides 170A-B (as shown in the figure), or can be implemented as separate components attached to the frame 105 on the corresponding sides 170A-B. In addition, the temples 110A-B can also be integrated into the temples 125A-B attached to the frame 105.

[0066] In one example, the see-through image display includes a first see-through image display 180C and a second see-through image display 180D. The eye-mounted device 100 includes first and second openings 175A-B for fixing the first and second optical components 180A-B, respectively. The first optical component 180A includes a first see-through image display 180C (e.g., Figure 2C The second optical assembly 180B includes a second see-through image display 180D (e.g., Figure 2C The continuous field of view of the continuous display images includes a viewing angle between approximately 15° and 30° measured horizontally, vertically or diagonally, specifically 24°. The continuous display images with a continuous field of view represent a combined three-dimensional observable area visible by stitching together the two display images presented on the first and second image displays.

[0067] As used herein, "angle of view" describes the angular range of the field of view associated with the displayed images presented in the left and right image displays 180C-D of the optical assemblies 180A-B, respectively. "Coverage angle" describes the angular range of the image that can be imaged by the lens of the visible light camera 114A-B or the infrared camera 220. Typically, the image circle produced by the lens is large enough to completely cover the film or sensor, which may include some vignetting (i.e., the brightness or saturation of the image is reduced toward the periphery compared to the center of the image). If the coverage angle of the lens does not fill the sensor, the image circle will be visible, usually with strong vignetting toward the edges, and the effective viewing angle is limited by the coverage angle. "Field of view" refers to the field of view of the observable area that the user of the eye-mounted device 100 can see through his eyes via the displayed images presented on the left and right image displays 180C-D of the optical assemblies 180A-B. The image display 180C of the optical assemblies 180A-B may have a field of view with a coverage angle between 15° and 30° (e.g., 24°) and a resolution of 480×480 pixels.

[0068] Figure 3 Shows Figure 2A The eye-mounted device 100 is provided with an infrared emitter 215, an infrared camera 220, a front portion of the frame 330, a rear portion of the frame 335, and a circuit board 340. Figure 3 As can be seen in FIG. 1 , the upper portion of the left frame of the eyewear frame of the eyewear device 100 includes a frame front portion 330 and a frame rear portion 335. An opening for the infrared emitter 215 is located on the frame rear portion 335.

[0069] As shown in the cross-sectional view 4 of the upper left frame of the frame, a circuit board, namely a flexible printed circuit board 340, is sandwiched between the frame front 330 and the frame rear 335. This figure also shows a detailed view of the left temple 110A connected to the left temple 325A via the left hinge 326A. In some examples, components of the eye movement tracker 213, including the infrared transmitter 215, the flexible printed circuit board 340 or other electrical connectors or contacts can be arranged on the left temple 325A or the left hinge 326A.

[0070] Figure 4 is a cross-sectional view through the infrared emitter 215 and the frame, corresponding to Figure 3 A circumferential cross section 4 of the eyewear device is shown. Figure 4The cross-section shown shows multiple layers of the eye-mounted device 100. As shown in the figure, the frame includes a frame front portion 330 and a frame rear portion 335. The flexible printed circuit board 340 is disposed on the frame front portion 330 and connected to the frame rear portion 335. The infrared emitter 215 is disposed on the flexible printed circuit board 340 and covered by the infrared emitter cover lens 445. For example, the infrared emitter 215 is attached to the back of the flexible printed circuit board 340 by reflow soldering. Reflow soldering attaches the infrared emitter 215 to the contact pads arranged on the back of the flexible printed circuit board 340 by applying melted solder paste to the flexible printed circuit board 340 at a controlled high temperature to connect the two components. In one example, the infrared emitter 215 is surface-mounted on the flexible printed circuit board 340 by reflow soldering, and the two components are electrically connected. However, it should be understood that, for example, through holes can be used to connect the leads from the infrared emitter 215 to the flexible printed circuit board 340 by interconnection.

[0071] The frame back 335 includes an infrared emitter opening 450 for an infrared emitter cover lens 445. The infrared emitter opening 450 is disposed on the rearward side of the frame back 335 and is configured to face inwardly toward the user's eyes. In this example, the flexible printed circuit board 340 may be coupled to the frame front 330 via a flexible printed circuit board adhesive 460. The infrared emitter cover lens 445 may be coupled to the frame back 335 via an infrared emitter cover lens adhesive 455. Indirect coupling via an intermediate component may also be employed.

[0072] In one example, the processor 932 uses the eye movement tracker 213 to determine whether Figure 5 The eye gaze direction 230 of the wearer's eye 234 is shown, and Figure 6 The eye position 236 of the wearer's eye 234 within the eye movement range is shown. The eye movement tracker 213 is a scanner that uses infrared light illumination (e.g., near infrared, short wavelength infrared, medium wavelength infrared, long wavelength infrared, or far infrared) to capture images of changes in infrared light reflection from the eye 234 to determine the gaze direction 230 of the pupil 232 of the eye 234 and the position 236 of the eye relative to the see-through display 180D.

[0073] Figure 7 An example of capturing visible light with a camera is shown. The left visible light camera 114A with the left visible light camera field of view 111A captures visible light to form a left raw image 758A. The right visible light camera 114B with the right visible light camera field of view 111B captures visible light to form a right raw image 758B. By processing the left raw image 758A and the right raw image 758B, the processor 932 generates a three-dimensional depth map 715 of the three-dimensional scene, hereinafter referred to as an image.

[0074] Fig. 8A Shown is a perspective view of an exemplary ultra-extendable eyewear device hinge assembly 1000, which includes a hinge 1001 rotatably fixed to a cap hinge 1006 and configured to allow a left temple 125A to rotate relative to a fixed left temple 110A. As shown, the left temple 110A can form a part of the frame 105, and the left temple 110A can also be considered an extension of the frame. Fig.11 As shown, the cap hinge 1006 is fixed to the distal end of the left temple 110A by a screw base 1009. A tension pin 1010 is fixed to the hinge 1001 and extends radially therefrom. Fig. 8A , Figure 8B and Figure 8C As shown, the stretch pin 1010 has a dual purpose and is configured to allow the left temple 125A to rotate outwardly relative to the left temple 110A in a hyper-extended manner. The configuration of the stretch pin 1010 also allows the left temple 125A to linearly extend along the axis of the stretch pin 1010 and the hinge 1001. The hinge assembly 1000 can also be disposed between the right temple 110B and the right temple 125B.

[0075] Figure 8B 1 is a top view of the hinge assembly 1000 in the super-extended position. The outwardly extending protrusion 1002 is arranged on the flange of the cap hinge 1006, and the protrusion 1002 faces the groove 1004 formed in the decorative trim 1008 fixed to the proximal end of the left temple 125A. The protrusion 1002 extends laterally and acts as a cam when the left temple 125A is super-extended, so that the protrusion 1002 pries the decorative trim 1008 to form a gap 1007 between the sharp edges of the temple to prevent the temple from being worn, such as Fig.12 shown.

[0076] Figure 8C Shown is a rear perspective view of the super-extension hinge assembly 1000. As shown, the hinge 1001 is arranged in the cap hinge 1006. Fig.14A -C discusses this feature further.

[0077] Fig. 9A Shown is a top perspective view of the left temple 125A folded inwardly from the fixed left temple 110A. The proximal end of the decorative trim 1008 facing the cap hinge 1006 includes a stretch groove 1004. The shape and size of the groove 1004 are commensurate with the protrusion 1002 and accommodate the protrusion 1002 when the left temple 125 is in the open (non-hyper-extended) position. As previously described, when the hinge 1001 is rotated outwardly from the open position to the cap hinge 1006, the left temple 125A is folded inwardly. Figure 8BIn the super-extended position shown, the protrusion 1002 slides laterally out of the groove 1004 and acts as a cam to create a lever action and form a gap 1007. In another example, the protrusion 1002 and the groove 1004 can have other shapes, such as a simple circular protrusion and circular groove that form a shallow depression, and are not limited to the specific shapes of each. The stretching protrusion 1002 and the stretching groove 1004 are preferred shapes because they can better align the left temple 125A with the left temple 110A to be firmly rotated outward, for example, to a 90 degree angle.

[0078] Fig. 9B Shown is a bottom perspective view of left temple 125A folded closed relative to fixed left temple 110A. Note that the flexible printed circuit (FPC) is encapsulated in hinge 1001 and is not visible, as will be discussed further below.

[0079] Fig.10 Shown is a top cross-sectional view of the left temple 125A in an open position relative to the left temple 110A. As shown, the protrusion 1002 is disposed in the groove 1004. Fig.10 A tension pin 1010 is shown which is firmly coupled to the hinge 1001 at the proximal end and extends longitudinally within the left temple 125A. The pin 1010 is disposed within and surrounded by a spring 1012 which is secured within a rectangular bushing 1014. The distal end of the sliding pin has a shoulder 1016 and is disposed outside the bushing 1014. Fig.11 As shown, when the left temple 125A is fully hyperextended, the shoulder 1016 limits the movement of the bushing 1014 along the slide pin 1010. As shown, the flexible printed circuit 1022 is extended within the left temple 125A and under the guide member 1024, and has a pair of strain relief rings to assist in hyperextension and closure of the left temple 125A, which will be discussed later.

[0080] Fig.11Shown is a top perspective view of the left temple 125A in the hyper-extended position, showing the bushing 1014 sliding along the pin 1010 and extending to the distal end of the pin 1010 and engaging with the shoulder 1016, which limits the movement of the bushing 1014. This forms a gap 1017 between the hinge 1001 and the bushing 1014. When in this position, the spring 1012 is fully compressed, which creates a slight guide force to help the left temple 125A press comfortably on the user's head so that the user wears the eye-mounted device. The hinge 1001 has a flange 1003, and the narrow thin plate 1005 of the flange 1003 is configured as a flexible radius to bend the flexible printed circuit 1022. Although the flange 1003 can be designed to provide a rotation stop, the stop function of the temple hyper-extension is provided by the shoulder 1016 of the pin 1010. Fastener 1020 is disposed within friction block ring 1032 and extends within hinge 1001, thereby securing left temple 125A to left temple 110A.

[0081] Fig.12 The left temple 125A is shown closed relative to the left temple 110A, and the protrusion 1002 and groove 1004 defined in the cap hinge 1006 are shown.

[0082] Fig.13A FIG. 1 is a top perspective view of the pin 1010 disposed within the bushing 1014. Fig. 13B As shown, the distal end of the pin 1010 has a rectangular shoulder 1018, which extends firmly and passes through the distal end opening 1021 of the bushing 1014. The shoulder 1018 has the same size and shape as the bushing opening 1021. The shoulder 1018 engages the distal end of the spring 1012 to hold and compress the spring 1012 in the bushing 1014 in the super-extended position. The shoulder 1018 is also used to reduce the amount of rotation of the shaft along its central axis. If the width of the shoulder 1018 is greater than the rest of the pin 1010, the angle at which the shoulder 1018 contacts the bushing 1014 can be reduced. The fastener 1030 fixes the proximal end of the pin 1010 to the hinge 1001. The hinge 1001 is rotatably arranged in the cap hinge 1006.

[0083] Fig. 13C Shown is a side cross-sectional view of the flexible printed circuit 1022 extending within the left temple 125A, see Fig.10 The left temple 125A has a guide member 1024 ( Fig.10 ), the guide member 1024 forms a first channel 1027 for accommodating the flexible printed circuit 1022, and forms a first auxiliary loop 1026 for the flexible printed circuit 1022. Fig.11As shown, the first auxiliary loop 1026 forms a strain relief that straightens the flexible printed circuit 1022 when the bushing 1014 slides outward in the super-extended position. The hinge 1001 has a second channel 1028 formed in the hinge 1001, and when the hinge is rotated from the closed position to the open position and the super-extended position, and the bushing 1014 is extended along the pin 1010, the second channel 1028 accommodates the flexible printed circuit 1022 and forms a second auxiliary loop 1034. The first auxiliary loop 1026 and the second auxiliary loop 1034 are separated from each other by the hinge 1001 and are located on opposite sides of the second channel 1028.

[0084] Fig.13D Shown is a first auxiliary loop 1026 formed on the bushing 1014 when the first temple 125A is in the closed position. When the bushing 1014 is extended along the length of the pin 1010, the first auxiliary loop 1026 straightens and the flexible printed circuit 1022 slides within the first channel 1027.

[0085] Fig.13E Hinge 1001 is shown retracted against bushing 1014 with spring 1012 pushing shoulder 1016 to provide a retraction force.

[0086] Fig.14A , Fig. 14B and Fig. 14C FIG. 1 shows a process in which the protrusion 1002 slides out of the groove 1004 of the cap hinge 1006 and forms a cam when the hinge 1001 is over-extended, see FIG. Figure 8B The aforementioned content.

[0087] Fig.14A The left temple 125A is shown in an open position, wherein the protrusion 1002 is disposed in the groove 1004. Fig. 14B As shown, when the hinge 1000 begins to hyperextend, the protrusion 1002 slides along the edge of the groove 1004 and partially exits the groove 1004, forming a cam and a gap 1007. The bushing 1014 slides along the pin 1010. Fig. 14C As shown, when the hinge 1000 is fully extended, the protrusion 1002 completely exits the groove 1004. Fig.11 As shown, bushing 1014 is now fully extended along pin 1010 and engages shoulder 1018. Both protrusion 1002 and groove 1004 have been stretched to guide left temple 125A to a super-extended position in a predetermined direction, for example, 110 degrees to left temple 110A.

[0088] Fig.15Shown is an exploded view of the assembled components shown in the illustrated view. Optionally, a foam tape 1028 may be used to secure the flexible printed circuit 1022 within the hinge 1000.

[0089] Fig.16 Shown is a high-level functional block diagram of example electronic components arranged within the eye-mounted devices 100 and 200. The electronic components shown include a processor 932, a memory 934, and see-through image displays 180C and 180D.

[0090] The memory 934 includes instructions executed by the processor 932 to implement the functions of the eye-mounted device 100 / 200, including instructions for the processor 932 to control the image 715. The processor 932 receives power from a battery (not shown) and executes instructions stored in the memory 934, or is integrated with the processor 932 on a chip, to perform the functions of the eye-mounted device 100 / 200 and communicate with external devices via a wireless connection.

[0091] The user interface adjustment system 900 includes a wearable device that is equipped with an eye movement tracker 213 (e.g., Figure 2B 9 (shown as an infrared emitter 215 and an infrared camera 220). The user interface adjustment system 900 also includes a mobile device 990 and a server system 998 connected via various networks. The mobile device 990 can be a smartphone, a tablet, a laptop, an access point, or any other such device capable of connecting to the eye-mounted device 100 using both a low-power wireless connection 925 and a high-speed wireless connection 937. The mobile device 990 accesses the server system 998 and the network 995. The network 995 can include any combination of wired and wireless connections.

[0092] The eye-mounted device 100 includes at least two visible light cameras 114A-B (one associated with the left side 170A and one associated with the right side 170B). The eye-mounted device 100 also includes two perspective image displays 180C-D of the optical assembly 180A-B (one associated with the left side 170A and one associated with the right side 170B). The eye-mounted device 100 also includes an image display driver 942, an image processor 912, a low power circuit 920, and a high speed circuit 930. The components for the eye-mounted device 100 shown in FIG. 9 are located on one or more circuit boards in the temples, such as a printed circuit board or a flexible printed circuit board. Alternatively, in addition, the components shown may be arranged in the temples, frames, hinges, or nose bridges of the eye-mounted device 100. The left and right visible light cameras 114A-B may include digital camera elements, such as complementary metal oxide semiconductor (CMOS) image sensors, charge coupled devices, lenses, or any other corresponding visible light or light capturing elements that can be used to capture data, including images of scenes with unknown objects.

[0093] The eye movement tracking program 945 executes the user interface field of view adjustment instructions, including causing the eye-mounted device 100 to track eye movements of the eye of the user of the eye-mounted device 100 through the eye movement tracker 213. Other implemented instructions (functions) may cause the eye-mounted device 100 to determine field of view adjustment for the initial field of view of the initial display image based on the detected eye movement of the user corresponding to the continuous eye direction. Further implemented instructions generate continuous display images according to the display image sequence based on the field of view adjustment. The continuous display images are provided to the user as visual output through the user interface. The visual output appears on the optical assembly 180A-B perspective image display 180C-D, which is driven by the image display driver 942 to present a display image sequence, including an initial display image with an initial field of view and a continuous display image with a continuous field of view.

[0094] like Fig.16 As shown, the high-speed circuit 930 includes a high-speed processor 932, a memory 934, and a high-speed wireless circuit 936. In an example, an image display driver 942 is coupled to the high-speed circuit 930 and is operated by the high-speed processor 932 to drive the left and right image displays 180C-D of the optical assembly 180A-B. The high-speed processor 932 can be any processor capable of managing the high-speed communications required by the eye-mounted device 100 and any general computing system operations. The high-speed processor 932 includes the processing resources required to manage high-speed data transmission to a wireless local area network (WLAN) over a high-speed wireless connection 937 using the high-speed wireless circuit 936. In some examples, the high-speed processor 932 executes an operating system of the eye-mounted device 100, such as a LINUX operating system or other such operating system, and the operating system is stored in the memory 934 for execution. In addition to any other tasks, the high-speed processor 932, which executes the software architecture of the eye-mounted device 100, is used to manage data transmission with the high-speed wireless circuit 936. In some examples, high-speed wireless circuit 936 is configured to implement the Institute of Electrical and Electronics Engineers (IEEE) 802.11 communication standard, also referred to herein as Wi-Fi. In other examples, other high-speed communication standards can be implemented by high-speed wireless circuit 936.

[0095] The low power wireless circuit 924 and the high speed wireless circuit 936 of the eye-mounted device 100 may include a short range transceiver (Bluetooth TM ) and a wireless wide area, local area or wide area network transceiver (e.g., cellular or WiFi). The mobile device 990 includes a transceiver that communicates via a low power wireless connection 925 and a high speed wireless connection 937, and can be implemented using details of the architecture of the eye-mounted device 100, as can other elements of the network 995.

[0096] The memory 934 includes any storage device capable of storing various data and applications, including color maps, camera data generated by the left and right visible light cameras 114A-B and the image processor 912, and display images generated by the image display driver 942 on the see-through image display 180C-D of the optical assembly 180A-B. Although the memory 934 is shown as being integrated with the high-speed circuit 930, in other examples, the memory 934 can be a separate component of the eye-mounted device 100. In some such examples, the circuit line can provide a connection from the image processor 912 or the low-power processor 922 to the memory 934 through a chip including the high-speed processor 932. In other examples, the high-speed processor 932 can manage the addressing of the memory 934 so that the low-power processor 922 will direct the high-speed processor 932 whenever a read or write operation involving the memory 934 is required.

[0097] The server system 998 can be one or more computing devices as part of a service or network computing system, such as a processor, a memory, and a network communication interface, to communicate with the mobile device 990 and the eye-mounted device 100 through the network 995. The eye-mounted device 100 is connected to the host. For example, the eye-mounted device 100 is paired with the mobile device 990 via the high-speed wireless connection 937, or connected to the server system 998 via the network 995.

[0098] The output components of the eye-mounted device 100 include visual components, such as Figure 2C -D) of the left and right image displays 180C-D of the optical components 180A-B described in FIG. 1 (e.g., a display such as a liquid crystal display (LCD), a plasma display panel (PDP), a light emitting diode (LED) display, a projector, or a waveguide). The image displays 180C-D of the optical components 180A-B are driven by the image display driver 942. The output components of the eye-mounted device 100 also include acoustic components (e.g., speakers), tactile components (e.g., vibration motors), other signal generators, etc. The input components of the eye-mounted device 100, the mobile device 990, and the server system 998 may include alphanumeric input components (e.g., keyboards, touch screens configured to receive alphanumeric inputs, optical keyboards, or other alphanumeric input components), point-based input components (e.g., mice, touch pads, trackballs, joysticks, motion sensors, or other pointing instruments), tactile input components (e.g., physical buttons, touch screens or other tactile input components that provide touch positions and forces or touch gestures), audio input components (e.g., microphones), etc.

[0099] The eye-mounted device 100 may optionally include additional peripheral device elements 919. Such peripheral device elements may include biometric sensors, additional sensors, or display elements integrated with the eye-mounted device 100. For example, the peripheral device elements 919 may include any input / output components, including output components, motion components, position components, or any other such components described herein. The eye-mounted device 100 may take other forms and may be combined with other types of frames, such as headgear, headphones, or helmets.

[0100] For example, the biometric components of the user interface field of view adjustment 900 include components for detecting expressions (e.g., hand expressions, facial expressions, voice expressions, body postures, or eye tracking), measuring biological signals (e.g., blood pressure, heart rate, body temperature, sweating, or brain waves), identifying people (e.g., voice recognition, retinal recognition, facial recognition, fingerprint recognition, or electroencephalogram-based recognition), etc. The motion components include acceleration sensor components (e.g., accelerometers), gravity sensor components, rotation sensor components (e.g., gyroscopes), etc. The position components include position sensor components for generating position coordinates (e.g., global positioning system (GPS) receiver components), WiFi or Bluetooth components for generating positioning system coordinates, etc. TM transceiver, altitude sensor component (e.g., an altimeter or barometer that detects air pressure from which altitude can be derived), direction sensor component (e.g., a magnetometer), etc. Such positioning system coordinates can also be received from the mobile device 990 via the low power wireless circuit 924 or the high speed wireless circuit 936 via the wireless connections 925 and 937.

[0101] According to some examples, an "application" is a program that performs the functions defined in a program. Various programming languages ​​can be used to create one or more applications structured in various ways, such as object-oriented programming languages ​​(e.g., Objective-C, Java, or C++) or programming languages ​​(e.g., C or assembly language). In certain examples, third-party applications (e.g., applications created by entities other than the vendor of a specific platform using ANDROID TM or IOS TM Software Development Kit (SDK) applications can be developed on IOS TM ANDROID TM , Mobile software running on a mobile operating system such as iOS or other mobile operating systems such as iPhone. In this example, the third-party application can call the API provided by the operating system to facilitate the functions described in this article.
