1. A method to track gaze of a user within a user view screen, the method comprising:
combining gaze tracking with head movement tracking,
wherein head movements of the head movement tracking provide a rough estimate of a direction of the gaze of the user, while eye movements of the gaze tracking provide fine tuning of the direction of the gaze of the user within the user view screen, and
wherein the head movement tracking provides rough estimate of a direction in which a user's head is facing;
dividing the user view screen into a plurality of gaze zones when gaze zone estimation is turned on; and
combining the gaze tracking with the gaze zone estimation to select a gaze zone from the plurality of gaze zones as the direction of the gaze of the user,
wherein the selected gaze zone provides the fine tuning of the direction of the gaze of the user within the user view screen and provides a more detailed estimation of the direction in which the user's head is facing.
