EyeAsteroids, an Asteroids clone and frustratingly missed pun opportunity, is an arcade game from Tobii Technology that uses the company's proprietary eye-tracking solutions to recognize where you are looking on the screen, without the use of any other human interfaces. By bouncing invisible infrared lights off of the player's corneas and then monitoring the changes in the reflections generated, the arcade cabinate can extrapolate the eyes' position in 3D space and determine the angle of their gaze.

"In other words, the eye tracker works much like you would if you face another person and estimate at what they are looking just by observing their eyes," according to Tobii Technology's layman-friendly website. Fifty EyeAsteroid cabinets have been produced at $15,000 a pop, which is roughly the cost of one and a half Street Fighter 4 head-to-head vs. cabinets. If you happen to live in jolly ol' London Towne, an EyeAsteroid cab will be on display at the Trocadero until February 17.
