The Descry product is an eye-tracking system that requires only a webcam, a pair of goggles, and a computer running Windows 2000, Windows XP or Windows Vista (experimental support). We may expand system compatability in the future based on Webcam driver support. Our system was written using the Sun Java programming language in order to interpret an image that it obtains from a webcam. It then uses that data to scroll through a set of letters and numbers and make a selection, allowing for a user to type without needing to use a keyboard.
