Disabled users have long been able to control computers
with just the flick of an eye, but those hardware and software packages are prohibitively expensive. Heck, the surprisingly accurate Tobii PCEye
is a veritable steal at $6,900. And, while we can't vouch for its usability, engineering students at Brigham Young University have managed an impressive feat, by whipping up an eye-tracking Windows 7 tablet that costs under $1,500. The system was created as part of a partnership with EyeTech Digital Systems, which plans to market the devices in parts of the world where other eye-tracking solutions are unaffordable -- like just about anywhere the roads aren't paved with gold. We could even see a few able-bodied (but incredibly lazy) bloggers getting some use out of this -- mornings around here would be a lot easier if we could double-fist piping hot coffee mugs while typing with our eyeballs.
