Abstract
An eye tracking device including 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 one or more pixels of said optical sensor, and a controller, which is connected to said optical sensor and configured to: a) receive the signal stream of events from the optical sensor, b) generate an inference frame based on the stream of events, c) utilize the inference frame as input to a machine learning module and operate the machine learning module to obtain output data, and e) extract from the output data information related to the eye of the user, wherein the controller is configured to generate the inference frame utilizing a first artificial neural network.
