Title
(EN) METHOD, APPARATUS, DISPLAY DEVICE AND STORAGE MEDIUM FOR POSITIONING GAZE POINT
(FR) PROCÉDÉ, APPAREIL, DISPOSITIF D'AFFICHAGE ET SUPPORT DE STOCKAGE POUR POSITIONNER UN POINT DE REGARD
Abstract
(EN)
Disclosed herein includes a method, an apparatus, a display device and storage medium storing computer executable instructions for positioning a gaze point. The method for obtaining a gaze point in a display device may comprise capturing a real time eye image, obtaining a real time pupil center point from the real time eye image, determining a gaze target zone based on the real time pupil center point and obtaining a gaze point on a target screen generated by the display device based on the real time pupil center point and a mapping ratio for the gaze target zone.
(FR)
L'invention concerne un procédé, un appareil, un dispositif d'affichage et un support de stockage mémorisant des instructions exécutables par ordinateur pour positionner un point de regard. Le procédé permettant d’obtenir un point de regard dans un dispositif d'affichage peut consister à : capturer une image d'œil en temps réel ; obtenir un point central de pupille en temps réel à partir de l'image de l'œil en temps réel ; déterminer une zone cible de regard d’après le point central de la pupille en temps réel ; et obtenir un point de regard sur un écran cible généré par le dispositif d'affichage d’après le point central de la pupille en temps réel et un rapport de mappage pour la zone cible du regard.
