Tobii Rex Windows 8

                           Tobii Rex Windows 8

Eye-tracking technology has been around for quite some time, but the Tobii Rex sensor does it in a way that actually seems practical. As a simple Windows 8 tech demo, being able to move up and down an Internet Explorer tab or or open an application with no more than a look and the press of a key is pretty incredible. Tobii’s plan to get these onto ultrabooks and tablets at a relatively low cost is what is truly exciting though.
