Eye tracking device, eye tracking method, and computer-readable medium

Abstract

An eye tracking device that includes: an event-based optical sensor configured to receive radiation reflected off an eye of a user and produce a signal stream of events, each event corresponding to detection of a temporal change in the received radiation at pixels of the sensor; glint sources configured to send radiation to the eye that is reflected off the cornea and received by the sensor in the form of individual glints; a controller connected to the sensor and configured to receive the signal stream from the sensor and to generate: gaze information of the eye and first glint information of the glints, at a first instant of time; and second glint information of the glints at a second instant of time that is later than the first instant of time. The controller is configured to generate predicted gaze information at the second instant of time.
