Abstract
Stereo gaze tracking estimates a 3-D gaze point by projecting determined right and left eye gaze points on left and right stereo images. The determined right and left eye gaze points are based on one or more tracked eye gaze points, estimates for non-tracked eye gaze points based upon the tracked gaze points and image matching in the left and right stereo images, and confidence scores indicative of the reliability of the tracked gaze points and/or the image matching.
