Abstract
A display apparatus including display or projector, means for tracking position and orientation of user's head, and processor coupled to display or projector and said means. The processor or external processor communicably coupled to processor is configured to obtain head-tracking data indicative of position and orientation; process head-tracking data to determine current position and orientation of user's head and velocity and/or acceleration with which position and orientation is changing; predict first and second position and orientation of user's head at time tand t, respectively; determine first and second projection matrices to be applied to three-dimensional image data of given frame, respectively; and apply first and second projection matrices to said image data to generate first image frame and second image frame, respectively. Processor is configured to render first and second image frame at time tand t, respectively.
