Five Mixed Reality Headset Patents were published today covering Gaze Tracking, Lenticular Displays and more
Today the US Patent & Trademark Office published another series of patent applications from Apple that relate to their future Mixed Reality Headset. The first in this series relates to gaze tracking, and in particular, to systems, methods, and devices for gaze tracking using a light source direction of a light source used to produce one or more glints on the surface of the eye. The other patent applications cover Multimodal Inputs; Presenting Synthesized Reality Companion Content; and Optical Film Arrangements.
Some existing gaze tracking systems use light reflected off of the surface of the eye to estimate gaze directions. Such techniques may estimate the user s gaze direction using multiple glints to identify locations along the user s gaze (e.g., pupil center, eye center, and cornea center) or by identifying the user s eye shape, position, and orientation.
