  • Patent number: 6637883
    Abstract: An eye-tracking system for displaying a video screen pointer at a point of regard of a user's gaze. The system comprises a camera 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 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. The processing performed by the computer includes a fine-tuning capability for positioning the cursor at point on the video screen substantially overlapping the point of regard, and a gaze activated method for selecting computer actions.
