Abstract
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.
