Title
(EN) METHOD FOR EYE GAZE TRACKING
(FR) PROCÉDÉ DE SUIVI DE 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.
(FR) L'invention concerne un procédé mis en œuvre par ordinateur pour localiser un point de regard sur un écran (151). Le procédé comprend l'étape (210) consistant à initier l'acquisition d'une image (300) et les étapes (220, 230) consistant à initier la localisation d'un emplacement de premier point de repère de visage (301) et d'un emplacement de second point de repère de visage (302) dans l'image (300). Le procédé comprend en outre l'étape (240) consistant à initier la sélection d'une région d'intérêt (310) dans l'image (300), ladite sélection étant effectuée en utilisant les emplacements de point de repère mentionnés ci-dessus (301, 302). Le procédé comprend l'étape (250) consistant à initier la construction d'un vecteur de regard, la construction du vecteur de regard étant effectuée au moyen d'un réseau neuronal artificiel en utilisant la première région d'intérêt (310) comme entrée. De plus, le procédé comprend l'étape (260) consistant à initier la localisation du point de regard sur l'écran (151), la localisation du point de regard étant effectuée au moyen du vecteur de regard.
