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.
