Abstract: A method comprising acquiring a set of voltage signals from a set of electrodes arranged in proximity to the ears of a user, based on the set of voltage signals, determining an EOG gaze vector in ego-centric coordinates, determining a head pose of the user in display coordinates, using a sensor device worn by the user, combining the EOG gaze vector and head pose to obtain a gaze vector in display coordinates, and determining a gaze point by calculating an intersection of the gaze vector and an imaging surface having a known position in display coordinates.
