Abstract

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.
