Tobii, which has developed an eye tracking technology made for Windows 8, has announced plans to launch a hardware add-on, Tobii REX, that will go on sale later in 2013 for any Windows 8 PC.
Ditch the mouse and instead control your computer with your eyes. We tested Tobii's Gaze technology by playing a game of "Eye Asteroids" and found the product worked exactly as expected: hands free.
Windows 8 is being used as a demo platform for Gaze, a new PC eye-tracking tool. The device, which can let users control PCs with their eyes, was revealed today and will be shown at CES 2012.
