Why Monitor Eye Movements?

Real-time knowledge of the position of the eye and the pupil diameter is invaluable for a host of diagnostic and interactive applications. Neurologists, ophthalmologists, psychologists, and brain researchers use eye data to test for cognition and oculomotor characteristics and abnormalities. Monitoring where a subject is looking allows creators of consoles, cockpits, advertisements, and packaging to optimize their designs or train users more efficiently. As a control input, eye movements can be used to direct a weapon, a cursor, or a high-resolution simulator inset to maximize overall system speed and utility.
