摘要： The invention relates to an eye tracking device, an eye tracking method, and a computer-readable medium. The eye tracking device comprises an event-based optical sensor (1 ), which is configured to receive radiation (12) reflected off an eye (2) of a user and produce a signal stream (3) of events (31 ), each event (31 ) corresponding to detection of a temporal change in the received radiation at one or more pixels of said optical sensor (1 ), and a controller (4), which is connected to said optical sensor (1 ) and configured to: a) receive the signal stream (3) of events (31 ) from said optical sensor (1 ), b) generate an inference frame (61 ) based on at least a portion of said stream (3) of events (31 ), c) utilize said inference frame (61 ) as input to a machine learning module (6) and operate said machine learning module (6) to obtain output data, and e) extract from said output data information related to said eye (2) of said user, wherein said controller (4) is configured to generate said inference frame (61 ) utilizing a first artificial neural network (5).

摘要： The invention relates to an eye tracking device, an eye tracking method, and a computer-readable medium. 1. Eye tracking device comprising: an event-based optical sensor (1 ), which is configured to receive radiation reflected off an eye (2) of a user and produce a signal stream (3) of events (31 ), each event (31 ) corresponding to detection of a temporal change in the received radiation at one or more pixels of said optical sensor (1 ); - one or more glint sources (11, 12) configured to send radiation to the eye (2) of a user such that said radiation is reflected off the cornea of said eye (2) and is received by said event-based optical sensor (1 ) in form of one or more individual glints; - a controller (4), which is connected to said optical sensor (1 ) and configured to receive the signal stream (3) of events (31 ) from said optical sensor (1 ) and to generate based on said signal stream (3) of events (31 ): - gaze information (P) of said eye (2) at a first instant of time; first glint information (M) of said one or multiple glints at said first instant of time; and - second glint information (Mt) of said one or multiple glints at a second instant of time that is later than the first instant of time, and wherein said controller (4) is configured to generate predicted gaze information (Pt) of said eye (2) at said second instant of time based on said second glint information (Mt).
