Tobii demonstrated its eyeball-tracking technology at CES last year, but this time it is announcing a 5,000 unit production run of a USB bar which can be stuck to the bottom of the monitor of any Windows 8 PC to start tracking eyeballs. Lenovo isn't even waiting that long. Although it is only tracking fingers, it's adding the capability to existing Yoga laptops courtesy of eyeSight Tech.
The Consumer Electronics Show (CES) kicks off next week but companies are already announcing what they're going to show in the hope of gaining some pre-show publicity, with better ways to control Windows 8 featuring prominently in the offerings."
