  • POSE-INVARIANT EYE-GAZE TRACKING USING A SINGLE COMMODITY CAMERA
    Publication number: 20190087001
    Abstract: A method, comprising: (a) measuring coordinates of four or five fiducial markers in facial images of a subject captured by a camera facing away from a screen toward the subject; (b) optimising and reducing a multivariate polynomial model that maps the measured coordinates of the four or five fiducial markers in the facial images to estimated coordinates of gaze targets of the subject on the screen; and (c) using the reduced multivariate polynomial model to map the measured coordinates of the four or five fiducial markers to the estimated coordinates of gaze targets of the subject on the screen.
