  • Publication number: 20080137909
    Abstract: A gaze position tracking method and apparatus for simply mapping one's gaze position on a monitor screen are provided. The gaze position tracking apparatus includes an image capturing module, and an image processing module. The image capturing module illuminates infrared rays to a user's eyes, reflects an illuminated eye image at 45°, and captures the 45° reflected eye image. The image processing module obtains a pupil center point of the illuminated eye image by performing a predetermined algorithm, and maps the pupil center point on a display plane of a display device through a predetermined transform function.
