NEW YORK — Ever wish your eyes were lasers? A prototype laptop brings that wish closer to reality.
It tracks your gaze and figures out where you're looking on the screen. That means, among other things, that you can play a game where you burn up incoming asteroids with a laser that hits where you look.
In the future, a laptop like this could make the mouse cursor appear where you're looking, or make a game character maintain eye contact with a player.
Tobii Technology Inc., the Swedish firm that's behind the tracking technology, says that rather than a replacement for the traditional mouse and keyboard or the newer touch-screen, the eye-tracking could be a complement, making a computer faster and more efficient to use.
