  • Patent number: 11906734
    Abstract: Computer-implemented methods of operating an augmented reality device can involve capturing camera images, processing the camera images, and displaying virtual display images. The camera images can be captured automatically using a camera disposed within an augmented reality device worn by a user. The camera images can be processed automatically using a processor located within the augmented reality device. The virtual display images can be displayed automatically to the user within the augmented reality device while the user is looking through the augmented reality device and simultaneously viewing real objects through the augmented reality device. The virtual display images can be based on the processed camera images. Additional steps can include accepting a first user input, storing camera image(s) on a memory located within the augmented reality device based on the first input, accepting a second user input, and displaying stored image(s) to the user based on the second input.

When the curved reflector reflects the polarized light sequentially passing through the polarization reflection film and the curved wave plate to the polarization reflection film through the curved wave plate, the curved wave plate converts the polarization direction of the polarized light. Finally, the polarization reflection film reflects the polarized light to the transparent substrate to generate a virtual image.

  • Patent number: 11782271
    Abstract: Computer-implemented methods of operating an augmented reality device can involve capturing camera images, processing the camera images, and displaying virtual display images. The camera images can be captured automatically using a camera disposed within an augmented reality device worn by a user. The camera images can be processed automatically using a processor located within the augmented reality device. The virtual display images can be displayed automatically to the user within the augmented reality device while the user is looking through the augmented reality device and simultaneously viewing real objects through the augmented reality device. The virtual display images can be based on the processed camera images. Additional steps can include accepting a first user input, storing camera image(s) on a memory located within the augmented reality device based on the first input, accepting a second user input, and displaying stored image(s) to the user based on the second input.

  • Patent number: 11762422
    Abstract: An electronic device may have a housing that separates an exterior region from an interior region. The housing may have a front layer on a front face of the housing and a rear layer on an opposing rear face of the housing. Sidewall structures may extend between the front and rear layers. The housing may form a head-mounted housing that is configured to be worn on a user's head. An internal frame may be mounted in the interior region. The internal frame may have a nose bridge structure that is coupled to the housing with a coupling member such as a coupling member formed from an elastomeric vibration damping material. Other portions of the frame such elongated laterally extending support members may not contact any portion of the housing and may therefore be isolated from the housing during drop events.

  • Patent number: 11747631
    Abstract: A head-mounted fixing device includes a head frame, a bracket and a headband. Two side frame portions of the head frame abut against two sides of a user’s head, and a front frame portion of the head frame is located between the two side frame portions and abuts against the user’s forehead. The headband is movably connected to two first adjusting members of the head frame, so the position of the front frame portion on the forehead can be adjusted by adjusting positions of the two first adjusting members on the headband. The bracket abuts against the top of the head. The headband can wrap around and abut against the back of the head. The head frame, the bracket and the headband abut against the head to restrict the head-mounted fixing device from moving relative to the head, so that the head-mounted fixing device may be worn without shaking.

  • Patent number: 11740466
    Abstract: An electronic device may include a display module that generates light and an optical system that redirects the light towards an eye box. The system may include an input coupler that couples the light into the waveguide. The input coupler may include a prism on the waveguide and a scanning mirror. The scanning mirror may receive the light through the waveguide and the prism and may reflect the light into the waveguide through the prism while being rotated over a set of orientations. The scanning mirror may fill a relatively large field of view eye box with a corresponding image frame despite the limited field of view of the image light produced by the display module. The orientation of the scanning mirror may be adjusted based on gaze tracking data.
