Playing 'pong' with the Blink of an Eye
Two cameras mounted outside a user's line of vision detect where his eyes are looking and uses that input to control a cursor or video game.

Imperial College London (ICL) students have developed an open source computer game where a player moves a bat to hit a ball using only eye movements. To play the game, the user wears special glasses with a built-in infrared light and a Webcam that records the movements of one eye. The Webcam is linked to a computer program that syncs the player's eye movements to the game.
The technology is inexpensive and can be purchased using off-the-shelf hardware costing about £25. "Remarkably, our undergraduates have created this piece of neurotechnology using bits of kit that you can buy in a shop, such as Webcams," says ICL's Aldo Faisal.
Researchers from Faisal's lab are currently refining the technology so that it can monitor movement in both eyes, which would allow a user to perform more complicated tasks such as plotting a route along the screen.
