[0035] The following description will partially set forth other objects, advantages, and novel features of the examples. These other objects, advantages, and novel features will be apparent to those skilled in the art upon review of the following text and the accompanying drawings, or may be learned by making or operating the examples. The objects and advantages of the present subject matter may be realized and obtained by the methods, instrumentalities, and combinations particularly pointed out in the appended claims.

[0036] 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 one skilled in the art that the present teachings can be practiced without these details. In other instances, well-known methods, procedures, components, and circuits are described at a relatively high level without detailed description to avoid unnecessarily obscuring aspects of the present teachings.

[0037] As used herein, the term "coupling" refers to any logical, optical, physical, or electrical connection, link, or the like, by which a signal or light generated or provided by one system component is transmitted to another coupled component. Unless otherwise specified, coupled components 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.

[0038] The orientations of the eyewear, related components, and any assembly incorporating an eye scanner and camera shown in any of the figures are examples only, for purposes of illustration and discussion. During operation of a particular variable optical processing application, the eyewear may be oriented in any other orientation suitable for the particular application of the eyewear, such as up, down, sideways, or any other orientation. Furthermore, as 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 merely as examples and do not limit the direction or orientation of any optical device or optical device component configured as described herein.

[0039] Reference will now be made in detail to the examples illustrated in the accompanying drawings and discussed below.

[0040] 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 with an image display 180D. 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.

[0041] Left and right visible light cameras 114A-B are equipped with image sensors sensitive to wavelengths in the visible light range. Each visible light camera 114A-B has a different forward-facing coverage angle. For example, visible light camera 114B has 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, for 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.

[0042] To present stereoscopic vision, the visible light cameras 114A-B may be coupled to an image processor (element 912 shown in FIG9 ) for digital processing and time stamping of scene images. The image processor 912 includes circuitry for receiving signals from the visible light cameras 114A-B and processing the signals from the visible light cameras 114A-B into a format suitable for storage in a memory (element 934 in FIG9 ). Timestamps may be added by the image processor 912 or other processors controlling the operation of the visible light cameras 114A-B. The visible light cameras 114A-B support stereo cameras simulating human binocular vision. The stereo camera has a function of generating a time stamp based on two captured images (element 934 in FIG9 ) having the same time stamp, respectively, from the visible light cameras 114A-B. Figure 7 Components 758A-B) to reproduce a three-dimensional image ( Figure 7 715). Such three-dimensional images 715 provide an immersive and realistic experience similar to 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 image pairs 758A-B generated from the forward-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 assemblies 180A-B can provide depth perception.

[0043] In an 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 see-through image display 180D (with an optical assembly 180B) configured to present 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.

[0044] Although Figure 1A Not shown, the eye-mounted device 100 also includes a head motion tracker ( Figure 1B 109) or an eye movement tracker ( Figure 2B9). 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, as 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 orientation or an initial eye gaze direction ( Figure 5 Element 230 in).

[0045] The processor 932 may also be programmed to configure the eye-mounted device 100 to detect movement of the eye-mounted device user by: (i) detecting movement of the eye-mounted device user via a head motion tracker ( Figure 1B 109) to track the user's head movements, or (ii) via an eye movement tracker ( Figure 2B 、 Figure 5 Element 213 in the eye-mounted device 100 tracks eye movements of a user of the eye-mounted device 100. Processor 932 executing programming may further configure the eye-mounted device 100 to determine a field of view adjustment for an initial field of view of an initial display image based on the detected user movement. The field of view adjustment may include a continuous field of view corresponding to continuous head orientations or continuous eye orientations. Processor 932 executing programming may further configure the eye-mounted device 100 to generate a continuous display image of a display image sequence based on the field of view adjustment. Processor 932 executing programming may further configure the eye-mounted device 100 to present the continuous display image through the see-through image displays 180C-D of the optical assemblies 180A-B.

[0046] Figure 1B yes Figure 1AA top cross-sectional view of the temple of the eyewear device 100 is shown, showing the right visible light camera 114B, the head motion tracker 109, and the circuit board. The configuration and mounting location of the left visible light camera 114A are substantially similar to those of the right visible light camera 114B, differing only in that it is connected and coupled to the left side 170A. As shown, the eyewear device 100 includes the right visible light camera 114B and a circuit board, which may be a flexible printed circuit board (PCB) 140. A right hinge 226B connects the right temple 110B to the right temple 125B of the eyewear device 100. In some examples, 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.

[0047] As shown, the eyewear device 100 is equipped with a head motion tracker 109, which includes, among other things, an inertial measurement unit (IMU). An IMU is an electronic device that uses a combination of accelerometers, gyroscopes, and sometimes a magnetometer to measure and report specific force, angular velocity, and sometimes the magnetic field surrounding the body. An IMU operates by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. A typical IMU configuration has three axes, each equipped with an accelerometer, gyroscope, and magnetometer: a horizontal axis for left and right movement (X), a vertical axis for up and down movement (Y), and a depth or distance axis for up and down movement (Z). The accelerometer detects the gravity vector. The magnetometer defines rotation in a magnetic field (e.g., facing south, north, etc.), acting like a compass that generates a heading reference. The three accelerometers detect acceleration along the horizontal, vertical, and depth axes defined above, which can be defined relative to the ground, the eyewear device 100, or the user wearing the eyewear device 100.

[0048] 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. Head movement includes a change in head orientation relative to an initial head orientation along a horizontal axis, a vertical axis, or a combination thereof during presentation of an initial display image on the image display. In one example, tracking the head movement of the user's head via the head movement tracker 109 includes measuring the initial head orientation 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 orientation along a horizontal axis, a vertical axis, or a combination thereof during presentation of the initial display image via the inertial measurement unit 109.

[0049] Tracking the head movement of the user's head via the head movement tracker 109 also includes determining a change in head orientation based on the initial head orientation and the subsequent head orientation. Detecting the user movement of the eyewear device 100 also includes, in response to tracking the user's head movement via the head movement tracker 109, determining that the change in head orientation exceeds a deviation angle threshold along a horizontal axis, a vertical axis, or a combination thereof. The deviation angle threshold is between approximately 3° and 10°. As used herein, the term "approximately" when referring to an angle means ±10% of the stated amount.

[0050] Changes along the horizontal axis can slide three-dimensional objects, such as characters, bitmaps, and application icons, 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 can display weather information, the time of day, the 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.

[0051] The right temple 110B includes a temple body 211 and a temple cap. Figure 1B The temple cap is omitted from the cross-section shown. The right temple 110B is internally arranged with various interconnected circuit boards, such as printed circuit boards or flexible printed circuit boards, including circuits for the right visible light camera 114B, microphone 130, speaker 132, low-power wireless circuits (e.g., for communication via Bluetooth), and the like. TM controller circuits for wireless short-range network communications), high-speed wireless circuits (e.g., for wireless local area network communications via WiFi).

[0052] 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 focuses through an opening formed in the right temple 110B. In some examples, the frame 105 coupled to the right temple 110B includes an opening for the visible light camera cover lens. The frame 105 includes a forward-facing side configured to face outwardly away from the user's eye. The visible light camera cover lens opening is formed on and through the forward-facing side. In this example, the right visible light camera 114B forms an outward coverage angle 111B with the line of sight or perspective of the right eye of the user of the eyewear device 100. The visible light camera cover lens can also be adhered to the outward-facing surface of the right temple 110B, wherein the outward-facing coverage angle forms a single opening but in a different outward direction. Indirect coupling via an intermediate component can also be used.

[0053] Left (first) visible light camera 114A is connected to left perspective image display 180C of left optical assembly 180A to generate a first background scene for a first continuously displayed image. Right (second) visible light camera 114B is connected to right perspective image display 180D of right optical assembly 180B to generate a second background scene for a second continuously displayed image. The first and second background scenes partially overlap to present a three-dimensional observable area for the continuously displayed image.

[0054] The flexible printed circuit board 140 is disposed within the right temple 110B and is connected to one or more other components disposed within the right temple 110B. Although the right visible light camera 114B is shown as being formed on a circuit board within the right temple 110B, it may alternatively be formed on a circuit board within the left temple 110A, temples 125A-B, or the frame 105.

[0055] Figure 2A FIG. 1 is a rear view of an example hardware configuration of an eye-mounted device 100 including 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 eyewear device 100 may take other forms and may be combined with other types of frames, such as headgear, headphones, or a helmet.

[0056] In the eyewear example, the eyewear device 100 includes a frame 105, which includes a right frame 107B and a left frame 107A. The right frame 107B is connected to the left frame 107A via a nose bridge 106 that fits the user's nose. The left and right frames 107A-B are each provided with openings 175A-B for securing respective optical elements 180A-B, such as lenses and see-through displays 180C-D. As used herein, the term lens refers to a transparent or translucent glass or plastic sheet with curved and flat surfaces that can converge / diverge light, or minimally converge / diverge light.

[0057] 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 can be integrated within the frame 105 on the respective sides 170A-B (as shown), or implemented as separate components attached to the frame 105 on the respective sides 170A-B. In addition, the temples 110A-B can also be integrated within temples attached to the frame 105 (not shown).

[0058] 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. 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 (as shown) are connected to the upper portion of the left frame 107A. The frame 105 or one or more left and right temples 110A-B include a circuit board (not shown) that 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.

[0059] Other arrangements of the infrared emitter 115 and the infrared camera 120 are possible, including: both the infrared emitter 115 and the infrared camera 120 can be located on the right frame 107B, or at different locations on the frame 105, for example, the infrared emitter 115 can be located on the left frame 107A and the infrared camera 120 can be located on the right frame 107B. In another example, the infrared emitter 115 can be located on the frame 105 and the infrared camera 120 can be located 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 to emit 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 to capture at least one reflection change in the infrared light emission pattern.

[0060] 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 portion of the frame 105, or in the temples 110A-B at both ends of the frame 105.

[0061] 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 left temple 210A of the eye-mounted device 200. 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.

[0062] and Figure 2A Similarly, the eyewear device 200 includes a frame 105, which includes a left frame 107A connected to a right frame 107B via 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.

[0063] 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 2CAs shown, optical assemblies 180A-B include 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. Optical assemblies 180A-B also include one or more optical layers 176, which may include lenses, optical coatings, prisms, reflectors, waveguides, optical strips, and any combination of other optical components. Optical layers 176A-N may include a prism of suitable size and configuration, having a first surface for receiving light from the display matrix and a second surface for emitting light toward the user's eye. The prism of optical layers 176A-N extends through all or at least a portion of respective openings 175A-B in left and right frames 107A-B, thereby allowing the user to see the second surface of the prism when the user's eye looks through the respective left and right frames 107A-B. The first surfaces of the prisms of optical layers 176A-N are arranged to face upward along the frame 105, with the display matrix overlying the prisms, ensuring that photons and light emitted from the display matrix strike the first surface. The prisms are sized and shaped to ensure that light is refracted within the prisms and directed toward the user's eye by the second surfaces of the prisms of optical layers 176A-N. In this regard, the second surfaces of the prisms of optical layers 176A-N can be convex to direct light toward the center of the eye. The prisms are optionally sized and shaped to magnify the image projected from the see-through image display 180C-D, with light passing through the prisms such that the image viewed from the second surface appears larger in one or more dimensions than the image emitted from the see-through image display 180C-D.

[0064] In another example, the see-through image displays 180C-D of the optical assemblies 180A-B include: Figure 2D The projected image display is shown. The optical assembly 180A-B includes a laser projector 150, which is a three-color laser projector that uses a scanning mirror or galvanometer. During operation, a light source such as the laser projector 150 is disposed within or on one of the temples 125A-B of the eyewear device 100. The optical assembly 180A-B includes one or more optical strips 155A-N spaced 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.

[0065] When photons projected from the laser projector 150 pass through the lenses of the optical assemblies 180A-B, the photons encounter light strips 155A-N. When a particular photon encounters a particular light strip, the photon is either redirected toward the user's eye or passed to the next light strip. The specific photons or beams can be controlled by combining laser projector 150 modulation with light strip modulation. In one example, the processor controls the light strips 155A-N by activating mechanical, acoustic, or electromagnetic signals. Although shown as having two optical assemblies 180A-B, the eye-mounted device 100 may also utilize other arrangements, such as a single or three optical assemblies, or may utilize different arrangements of the optical assemblies 180A-B depending on the application of the eye-mounted device 100 or the specific circumstances of the intended user.

[0066] like Figure 2C As further shown in FIG. 1-D , the eyewear device 100 is provided with a left temple 110A proximate to a left side 170A of the frame 105 and a right temple 110B proximate to a right side 170B of the frame 105. The temples 110A-B can be integrated within the frame 105 on the corresponding lateral sides 170A-B (as shown), or implemented as separate components attached to the frame 105 on the corresponding sides 170A-B. In addition, the temples 110A-B can be integrated within the temples 125A-B attached to the frame 105.

[0067] 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 the 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 150B). The continuous field of view of the continuous display images includes a viewing angle of between approximately 15° and 30°, specifically 24°, measured horizontally, vertically, or diagonally. The continuous display images with the 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.

[0068] As used herein, "angle of view" describes the angular range of the field of view associated with the displayed images presented on the left and right image displays 180C-D, respectively, of optical assemblies 180A-B. "Angle of coverage" describes the angular range of imagery that can be imaged by the lens of visible light cameras 114A-B or infrared camera 220. Typically, the image circle produced by the lens is large enough to completely cover the film or sensor, possibly including some vignetting (i.e., a decrease in image brightness or saturation toward the periphery compared to the center of the image). If the angular coverage of the lens does not fill the sensor, the image circle will be visible, typically with strong vignetting toward the edges, and the effective angle of view is limited by the angle of coverage. "Field of view" refers to the field of view of the observable area visible to the user of eye-mounted device 100 through their eyes via the displayed images presented on the left and right image displays 180C-D of optical assemblies 180A-B. Image display 180C of optical assemblies 180A-B may have a field of view with an angle of coverage between 15° and 30° (e.g., 24°) and a resolution of 480×480 pixels.

[0069] Figure 3 Shown 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, the upper portion of the left 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.

[0070] As shown in the encircled cross-section 4 of the upper left frame portion, a circuit board, namely a flexible printed circuit board 340, is sandwiched between the frame front portion 330 and the frame back portion 335. This figure also shows a detailed view of the connection between the left temple 110A and the left temple 325A via the left hinge 326A. In some examples, components of the eye movement tracker 213, including the infrared emitter 215, the flexible printed circuit board 340, or other electrical connectors or contacts, may be located on the left temple 325A or the left hinge 326A.

[0071] 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 depicts various layers of the eyewear device 100. As shown, the frame includes a frame front portion 330 and a frame rear portion 335. A 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 an 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 involves applying a controlled high temperature to the flexible printed circuit board 340 to melt solder paste, thereby attaching the infrared emitter 215 to contact pads disposed on the back of the flexible printed circuit board 340. In one example, reflow soldering is used to surface-mount the infrared emitter 215 on the flexible printed circuit board 340, electrically connecting the two components. However, it should be understood that leads from the infrared emitter 215 can be connected to the flexible printed circuit board 340 by interconnection, for example, using through-holes.

[0072] Frame rear portion 335 includes an infrared emitter opening 450 for an infrared emitter cover lens 445. Infrared emitter opening 450 is located on the rearward-facing side of frame rear portion 335 and is configured to face inward toward the user's eyes. In this example, flexible printed circuit board 340 can be coupled to frame front portion 330 via flexible printed circuit board adhesive 460. Infrared emitter cover lens 445 can be coupled to frame rear portion 335 via infrared emitter cover lens adhesive 455. Indirect coupling via an intermediate component may also be employed.

[0073] In an example, the processor 932 utilizes the eye movement tracker 213 to determine if 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 is shown within the eye movement range. 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.

[0074] Figure 7 An example of using a camera to capture visible light is shown. Left visible light camera 114A, with left visible light camera field of view 111A, captures visible light, forming left raw image 758A. Right visible light camera 114B, with right visible light camera field of view 111B, captures visible light, forming right raw image 758B. By processing left raw image 758A and right raw image 758B, processor 932 generates a 3D depth map 715 of the 3D scene, hereinafter referred to as an image.

[0075] Figure 8A Shown is a perspective view of an exemplary hyper-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 part of the frame 105, and the left temple 110A can also be considered an extension of the frame. Figure 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. Figure 8A 、 Figure 8B and Figure 8C As shown, the tension pin 1010 serves a dual purpose and is configured to allow the left temple 125A to rotate outward relative to the left temple 110A in a hyper-extension manner. The configuration of the tension pin 1010 also allows the left temple 125A to linearly extend along the axis of the tension pin 1010 and the hinge 1001. The hinge assembly 1000 may also be disposed between the right temple 110B and the right temple 125B.

[0076] Figure 8B FIG1 is a top view of the hinge assembly 1000 in the super-extended position. The outwardly extending protrusion 1002 is disposed on the flange of the cap hinge 1006, and the protrusion 1002 faces a 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, causing the protrusion 1002 to pry the decorative trim 1008 to form a gap 1007 between the sharp edges of the temple to prevent wear on the temple, such as Figure 12 shown.

[0077] Figure 8C Shown is a rear perspective view of the hyper-extension hinge assembly 1000. As shown, the hinge 1001 is arranged in the cap hinge 1006. Figure 14A -C discusses this feature further.

[0078] Figure 9A Shown is a top perspective view of the left temple 125A folded inward from the fixed left temple 110A. The proximal end of the decorative trim 1008 facing the cap hinge 1006 includes a tension 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 outward from the open position to the left temple 110A, the temple 125A is folded inward. Figure 8BIn the illustrated hyper-extended position, the protrusion 1002 slides laterally out of the groove 1004 and acts as a cam, creating a lever action and gap 1007. In another example, the protrusion 1002 and groove 1004 may have other shapes, such as a simple circular protrusion and circular groove forming a shallow depression, and no limitation is intended to be inferred regarding the particular shapes of each. The stretching protrusion 1002 and the stretching groove 1004 are preferred shapes because they better align the left temple 125A with the left temple 110A for secure outward rotation, for example, to a 90-degree angle.

[0079] Figure 9B Shown is a bottom perspective view of the left temple 125A folded closed relative to the fixed left temple 110A. Note that the flexible printed circuit (FPC) is enclosed in the hinge 1001 and is not visible, as will be discussed further below.

[0080] Figure 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. Figure 10 A tension pin 1010 is shown, which is securely coupled to the hinge 1001 at its 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. Figure 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 stretched 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.

[0081] Figure 11Shown is a top perspective view of the left temple 125A in the hyper-extended position, showing a bushing 1014 sliding along the pin 1010 and extending to the distal end of the pin 1010, where it engages a shoulder 1016, which limits its movement. This creates a gap 1017 between the hinge 1001 and the bushing 1014. In this position, the spring 1012 is fully compressed, creating a slight guiding force to help the left temple 125A rest comfortably on the user's head while the eyewear device is being worn. The hinge 1001 has a flange 1003 with a narrow sheet 1005 configured as a flexible radius to facilitate bending of the flexible printed circuit 1022. While the flange 1003 could be designed to provide a rotational stop, the stop for hyper-extension of the temple 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.

[0082] Figure 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.

[0083] Figure 13A FIG is a top perspective view of the pin 1010 disposed within the bushing 1014. Figure 13B As shown, the distal end of pin 1010 has a rectangular shoulder 1018 that extends securely through a distal opening 1021 of bushing 1014. Shoulder 1018 has the same size and shape as bushing opening 1021. Shoulder 1018 engages the distal end of spring 1012 to retain and compress spring 1012 within bushing 1014 in a hyperextended position. Shoulder 1018 also serves to reduce the amount of rotation of the shaft about its central axis. If shoulder 1018 is wider than the rest of pin 1010, the angle at which shoulder 1018 contacts bushing 1014 can be reduced. Fastener 1030 secures the proximal end of pin 1010 to hinge 1001. Hinge 1001 is rotatably disposed within cap hinge 1006.

[0084] Figure 13C Shown is a side cross-sectional view of the flexible printed circuit 1022 extending within the left temple 125A. Figure 10 As shown. The left temple 125A has a guide member 1024 ( Figure 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. Figure 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 therein that accommodates the flexible printed circuit 1022 and forms a second auxiliary loop 1034 when the hinge is rotated from the closed position to the open position and the super-extended position and the bushing 1014 extends along the pin 1010. 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.

[0085] Figure 13D 10. The first auxiliary loop 1026 formed on the bushing 1014 is shown 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.

[0086] Figure 13E Hinge 1001 is shown retracted against bushing 1014 with spring 1012 pushing shoulder 1016 to provide the retraction force.

[0087] Figure 14A 、 Figure 14B and Figure 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 overextended. Figure 8B shown.

[0088] Figure 14A The left temple 125A is shown in an open position with the protrusion 1002 disposed in the recess 1004. Figure 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 gap 1007. The bushing 1014 partially slides along the pin 1010. Figure 14C As shown, when the hinge 1000 is fully extended, the protrusion 1002 completely exits the groove 1004. Figure 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 into a super-extended position in a predetermined direction, for example, 110 degrees relative to left temple 110A.

[0089] Figure 15 Shown is an exploded view of the assembled components shown in the drawings. Optionally, foam tape 1028 can be used to secure the flexible printed circuit 1022 within the hinge 1000.

[0090] Figure 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.

[0091] 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.

[0092] The user interface adjustment system 900 includes a wearable device 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, tablet, laptop, 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.

The eye-mounted device 100 also includes two see-through image displays 180C-D (one associated with the left side 170A and one associated with the right side 170B) of the optical assembly 180A-B. 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 FIG9 are located on one or more circuit boards in the temples, such as printed circuit boards or flexible printed circuit boards. Alternatively, or in addition, the components shown may be arranged within the temples, frames, hinges, or nosepieces 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.

[0094] The eye movement tracking program 945 executes user interface field of view adjustment instructions, including causing the eye-mounted device 100 to track eye movements of the user of the eye-mounted device 100 via the eye movement tracker 213. Other implemented instructions (functions) may cause the eye-mounted device 100 to determine field of view adjustments for an initial display image based on detected eye movements of the user corresponding to successive eye directions. Further implemented instructions generate successive display images in a display image sequence based on the field of view adjustments. The successive display images are provided to the user as visual output via the user interface. The visual output appears on the see-through image displays 180C-D of the optical assemblies 180A-B, which are driven by the image display driver 942 to present a display image sequence, including an initial display image having an initial field of view and successive display images having successive fields of view.

[0095] like Figure 16 As shown, the high-speed circuitry 930 includes a high-speed processor 932, memory 934, and high-speed wireless circuitry 936. In an example, an image display driver 942 is coupled to the high-speed circuitry 930 and is operated by the high-speed processor 932 to drive the left and right image displays 180C-D of the optical assemblies 180A-B. The high-speed processor 932 can be any processor capable of managing the high-speed communications and any general-purpose computing system operations required by the eye-mounted device 100. 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 circuitry 936. In some examples, the high-speed processor 932 executes an operating system for 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. 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 circuitry 936, in addition to any other tasks. In some examples, high-speed wireless circuitry 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 circuitry 936.

[0097] The memory 934 comprises 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 images generated by the image display driver 942 for display on the see-through image displays 180C-D of the optical assemblies 180A-B. While 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 circuitry can provide a connection from the image processor 912 or the low-power processor 922 to the memory 934 via a chip including the high-speed processor 932. In other examples, the high-speed processor 932 can manage 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.

[0098] The server system 998 can be a service or network computing system, such as one or more computing devices including a processor, memory, and a network communication interface, to communicate with the mobile device 990 and the eye-mounted device 100 via 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 is connected to the server system 998 via the network 995.

[0099] 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 (e.g., displays such as liquid crystal displays (LCDs), plasma display panels (PDPs), light-emitting diode (LED) displays, projectors, or waveguides). The image displays 180C-D of the optical components 180A-B are driven by an 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, and the like. 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 input, optical keyboards, or other alphanumeric input components), point-based input components (e.g., mice, touchpads, trackballs, joysticks, motion sensors, or other pointing devices), tactile input components (e.g., physical buttons, touch screens or other tactile input components that provide touch location and force or touch gestures), audio input components (e.g., microphones), and the like.

[0100] The eye-mounted device 100 may optionally include additional peripheral components 919. Such peripheral components may include biometric sensors, additional sensors, or display components integrated with the eye-mounted device 100. For example, the peripheral components 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.

[0101] For example, the biometric components of user interface field of view adjustment 900 include components for detecting expressions (e.g., hand expressions, facial expressions, vocal expressions, body posture, or eye tracking), measuring biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identifying individuals (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 location components include location sensor components (e.g., Global Positioning System (GPS) receiver components) for generating location coordinates, WiFi or Bluetooth™ transceivers for generating location coordinates, altitude sensor components (e.g., altimeters or barometers for detecting air pressure from which altitude can be derived), direction sensor components (e.g., magnetometers), etc. Such location coordinates can also be received from mobile device 990 via low-power wireless circuitry 924 or high-speed wireless circuitry 936 via wireless connections 925 and 937.

[0102] 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, a third-party application (e.g., an application created by an entity other than the vendor of a specific platform using Android) TM or IOS TM Software Development Kit (SDK) can be used to develop applications on IOS TM ANDROID TM 、 Mobile software running on a mobile operating system such as the iPhone or other mobile operating systems. In this example, the third-party application can call the API provided by the operating system to facilitate the functions described in this article.
