GAZE TRACKING SYSTEM AND METHOD

摘要

An eye-tracking system (10) for displaying a video screen pointer (30) at a point of regard of a user's gaze. The system comprises a camera (14) focused on the user's eye; a support connected to the camera for fixing the relative position of the camera to the user's pupil; a computer (16) having a CPU, memory, video display screen, an eye-tracking interface, and computer instructions for: segmenting the digital pixel data of the image of the eye into black and white sections based upon user selectable RGB threshold settings; determining the center of the eye based upon the segmented digital data; mapping the determined center of the eye to a pair of coordinates on the video screen; and displaying a pointer on the video display screen at the point of the regard.
