A method and device for eye gaze estimation with regard to a sequence of images. The method comprises receiving a sequence of first video images and a corresponding sequence of first eye images of a user watching at the first video images; determining first saliency maps associated with at least a part of the first video images; estimating associated first gaze points from the first saliency maps associated with the video images associated with the first eye images; storing of pairs of first eye images/first gaze points in a database; for a new eye image, called second eye image, estimating an associated second gaze point from the estimated first gaze points and from a second saliency map associated with a second video image associated with the second eye image; storing the second eye image and its associated second gaze point in the database.

Method for calibration free gaze tracking using low cost camera

The invention relates to a method of gaze estimation. As to determine the position of the gaze without calibrating the system used for determining the gaze, the method comprises: detecting at least a location of the center of at least an eye on at least an eye image of a viewer watching at least a video image displayed on a screen; determining at least a first position of the gaze of the viewer on the screen by using the at least a detected location of the center of the at least an eye and a mapping function based on center-bias property of human gaze distribution. The invention also relates to a device configured for estimating the gaze.
