Methods and apparatuses for compensating for retinitis pigmentosa
11546527 · 2023-01-03 · ·

A system and methods for compensating for retinitis pigmentosa for a user include using a head-mounted and user-controllable device that can minify the image to more closely match the user's reduced field of view. The user may adjust the amount of minification and may also adjust the magnification of the image.

Dual system optical alignment for separated cameras

Improved techniques for generating images are disclosed herein. A first image is generated by an integrated camera. The pose of the computer system is determined based on the image, and a timestamp is determined. A detached camera generates a second image. The second image is aligned with the first image. An overlaid image is generated by overlaying the second image onto the first image based on the alignment. A pose difference is then identified between a current pose of the computer and the initial pose. Consequently, late stage reprojection (LSR) is performed on the overlaid image to account for the pose difference. The LSR-corrected overlaid image is then displayed.

DEVICE CASE INCLUDING A PROJECTOR

One disclosed example provides a method for displaying a hologram via a head-mounted display (HMD) device. The method comprises, via a camera system on the HMD device, acquiring image data capturing a surrounding environment by detecting illumination light output by a projector located on a case for the HMD device. A distance is determined from the HMD device to an object in the surrounding environment based upon the image data. The method further comprises displaying via the HMD device a hologram, the hologram comprising a left-eye image and a right-eye image each having a perspective based upon the distance determined.
