14. A system comprising:
a set of electrodes arranged in proximity to ears of a user and configured to acquire a set of voltage signals;
an electro-oculography (EOG) processing unit for determining an EOG gaze vector in ego-centric coordinates based on the set of voltage signals;
a user-worn sensor device for determining a head pose of the user in display coordinates;
a processing unit configured to:
combine the EOG gaze vector and the head pose to obtain a gaze vector in display coordinates; and
determine a gaze point by calculating an intersection of the gaze vector and an imaging surface having a known position in display coordinates.
