Holographic tracking

By integrating a miniature camera with holographic optics, Vision Control Systems (VCS; Oldham, England) eye-tracking technology uses the principles of retinal reflection to illuminate the subject`s eye with infrared light from a light-emitting diode. You`ll see how light reflected from the retina passes back through the pupil and provides an image at the camera; in addition, the VCS camera tracks the movement of reflected light and the pupil.

You`ll see how light reflected from the retina passes back through the pupil and provides an image at the camera; in addition, the VCS camera tracks the movement of reflected light and the pupil. The Web site also covers applications in computer games, pilot training, and advertising research.
