Apple patent application describes gaze tracking system with facial recognition
The U.S. Patent and Trademark Office has published a patent application by Apple for a gaze tracking system which could include a biometric sensor and gesture recognition capabilities, Patently Apple reports.
The system described involves the input-output circuitry of a computer or television gathering point-of-gaze information, vergence information, and head position information, and possibly applying facial recognition. Patently Apple refers to the sensors as a Face ID camera system. The device’s display surface could be reflective when the user looks directly at it, and change to make content visible when the user glances at an icon, or otherwise respond to user feedback.
The patent application, which was filed in Q4 2017, also says that the system could be used in an iPhone, iPad, or Apple Watch.
Apple recently received patents for ultrasonic fingerprint sensors and in-display fingerprint technology, as well as an infrared vein recognition system.
