  • Patent number: 11841510
    Abstract: Point to point transmission holograms are used to provide a scene camera for an augmented reality glasses display system. A glass or plastic substrate acts as spectacle style lens. A holographic medium is applied to a surface of the substrate, within which is recorded a series of point to point transmission holograms. The construction points of the holograms are arranged at the eye and at the pupil of a camera placed, ideally, to the temple side of the user's eye. The recorded transmission holograms act by diffracting a portion of the light from the scene surrounding the user that is heading for the user's eye towards the scene camera. The hologram efficiency is balanced so that the user is still able to see the surrounding scene. The perspective of the view seen by the scene camera is substantially identical to that seen by the user through the lens.

The display systems limit displaying content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer. The volume may be subdivided into two or more zones, including an innermost loss-of-fusion zone (LoF) in which no content is displayed, and one or more outer AVM zones in which the displaying of content may be stopped, or clipped, under certain conditions. For example, content may be clipped if the viewer is verging within an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration. A further possible condition for clipping content is that the user is verging on that content.

  • Patent number: 11490802
    Abstract: An ophthalmologic apparatus includes a data acquisition unit, a storage unit, and a correction unit. The data acquisition unit includes a concave mirror and an optical scanner configured to deflect light from a light source to guide to a reflective surface of the concave mirror. The data acquisition unit is configured to acquire a first data set group in an A-scan direction by performing optical coherence tomography on a subject's eye placed at a subject's eye position or a conjugate position of the subject's eye position using light reflected by the reflective surface. The storage unit is configured to store correction data for correcting an incident angle of the light at the subject's eye position depending on a deflection angle of the light by the optical scanner. The correction unit is configured to generate a second data set group by correcting at least a part of the first data set group based on the correction data stored in the storage unit.

  • Patent number: 11477430
    Abstract: Mathematical relationships between the scene geometry, camera parameters, and viewing environment are used to control stereography to obtain various results influencing the viewer's perception of 3D imagery. The methods may include setting a horizontal shift, convergence distance, and camera interaxial parameter to achieve various effects. The methods may be implemented in a computer-implemented tool for interactively modifying scene parameters during a 2D-to-3D conversion process, which may then trigger the re-rendering of the 3D content on the fly.

  • Patent number: 11064387
    Abstract: One exemplary implementation involves performing operations at an electronic device with one or more processors and a computer-readable storage medium. The device establishes a wireless communication link with a host device. The device receives, from the host device, a left eye frame and a right eye frame via a sequence of left eye frame transmissions and right eye frame transmissions. The device switches data transmissions schemes according to wireless commination link quality or eye gaze tracking. Adjusting transmission format based on transmission quality of the wireless communication link allows the devices to take advantage of greater bandwidth when available to save power. An additional transmission format is based on alternately transmitting left eye and right eye frames for very low bandwidth.
