(EN) METHOD FOR EYE GAZE TRACKING
(FR) PROCÉDÉ DE SUIVI DU REGARD
Abstract
(EN) The invention refers to a computer-implemented method for locating a point of gaze onto a screen (151). The method comprises the step (210) of initiating the acquiring of an image (300) and the steps (220, 230) of initiating the locating of a first face landmark location (301) and a second face landmark location (302) in the image (300). The method further comprises the step (240) of initiating the selecting of a region of interest (310) in the image (300), said selection being performed by using the aforementioned landmark locations (301,302). The method comprises the step (250) of initiating the constructing of a gaze vector, wherein the construction of the gaze vector is performed by means of an artificial neural network using the first region of interest (310) as input. Moreover, the method comprises the step (260) of initiating the locating the point of gaze onto the screen (151), wherein the locating of the point of gaze is performed by means of the gaze vector.
