DYNAMIC RENDER TIME TARGETING BASED ON EYE TRACKING

摘要

A head-mounted display (HMD) with a rolling illumination display panel can dynamically target a render time for a given frame based on eye tracking. Using this approach, re-projection adjustments are minimized at the location of the display(s) where the user is looking, which mitigates unwanted, re-projection-based visual artifacts in that "region of interest." For example, logic of the HMD may predict a location on the display panel where a user will be looking during an illumination time period for a given frame, determine a time, within that illumination time period, at which an individual subset of the pixels that corresponds to the predicted location will be illuminated, predict a pose that the HMD will be in at the determined time, and send pose data indicative of this predicted pose to an application for rendering the frame.
