Abstract
A method for estimating a gaze direction of a user includes acquiring an image of a face of the user, determining an approximate gaze direction based on a current head pose and a relationship between head pose and gaze direction, determining an estimated gaze direction based on detected eye features, determining a precise gaze direction based on glint position and eye features, and combining the approximate gaze direction and at least one of the estimated gaze direction and the precise gaze direction to provide a corrected gaze direction.
