US 2020/0050264 A1 · OPTICAL ENGINE TIME WARP FOR AUGMENTED OR MIXED REALITY ENVIRONMENT

Abstract

A device, system, and method for applying time warp in an augmented or mixed reality environment. An image may be rendered corresponding to an estimated head position calculated based on head position and orientation measured at the initial time. Time warp may be independently applied to each sequential one of the plurality of segmented visual units of an image (e.g., color-frames or pixel-groups) to generate a plurality of respective time warp visual units corresponding to a plurality of different respective estimated head position and orientations calculated based on head position and orientations measured at a plurality of different respective sequential times after the initial time. The plurality of time warp visual units may be projected in the sequential order at the augmented or mixed reality device.
