Abstract
A display apparatus including first and second displays or projectors that display first and second images for first and second eyes, respectively; first and second portions facing first and second eyes, respectively, first and second portions having first (F-F′) and second (S-S′) optical axes, respectively; means for tracking positions and orientations of first and second eyes relative to corresponding optical axes, respectively; and processor. The processor or external processor obtains current relative positions and orientations of both eyes; determines first and second transformations for first and second input image frames, respectively, given transformation being applied to correct apparent per-pixel distortions produced when given input image frame is displayed; and applies first and second transformations to generate first and second distortion-corrected image frames, respectively, wherein processor renders first and second distortion-corrected image frames.
