Title
(EN) SYSTEM AND METHOD FOR EYE TRACKING
(FR) SYSTÈME ET PROCÉDÉ DE SUIVI OCULAIRE
Abstract
(EN)
A system and method for eye tracking includes receiving an input image including at least a portion of a person's retina, finding a spatial transformation between the input image and a reference image, the reference image including at least a portion of the person's retina and calculating a change in orientation of an eye of the person corresponding to the spatial transformation. A processor may calculate, from the change in orientation an orientation of the person's eye associated with the input image, a direction of gaze associated with the input image, a gaze target associated with the input image and/or a ray of gaze associated with the input image.
(FR)
Un système et un procédé de suivi oculaire font appel à la réception d'une image d'entrée comprenant au moins une partie de la rétine d'une personne, la recherche d'une transformation spatiale entre l'image d'entrée et une image de référence, l'image de référence comprenant au moins une partie de la rétine de la personne et le calcul d'un changement d'orientation d'un œil de la personne correspondant à la transformation spatiale. Un processeur peut calculer, à partir du changement d'orientation, une orientation de l'œil d'une personne associée à l'image d'entrée, une direction de regard associée à l'image d'entrée, une cible de regard associée à l'image d'entrée et/ou un rayon de regard associé à l'image d'entrée.
