摘要
An optical array system for performing pupil tracking using retro-reflectivity includes: an LED array including at least one on-axis LED and at least one off-axis LED, for illuminating pupils of a user within an active region; a high-speed camera with a gaming motion sensor, for capturing images of the pupils illuminated by the LED array; and a processor, coupled to the high-speed camera, for receiving the captured images and performing processing algorithms on them to isolate pupil information and thereby determine pupil presence and location within the active region.
