So you're lazy and can't be bothered with using a mouse and keyboard to navigate your Windows 8 PC, what to do? Simple, use Tobii REX with its eye-tracking technology to make your computer usage life a little bit simpler.

Tobii has been trying its hands at eye tracking for quite some time, the company first showed off its Tobii REX eye-tracking tech at CES 2012 and at CeBIT, though after that the whole thing went under the radar. Fast forward to 2013 and Tobii is back in the news again, this time announcing that it is finally on the verge of producing 5,000 of its eye-tracking devices for Windows 8.

"Tobii REX Limited Edition is the first Gaze Interaction device on the market for consumers. A limited edition of 5,000 units will be available Fall 2013," notes the official site.

The plan is to sell them to consumers at an unspecified price and to developers for $995 a piece. It is not certain how accurate the Tobii REX is in real world use, consumers may require fairly powerful computers for the device to perform at optimum. However, the good news is that the device is not intended for use on its own, Tobii explains that it is designed for use along with the mouse and keyboard, so that's a good thing, right?

This kind of technology may be ahead of its time, and could possibly fade away into the realm of technologies that didn't make it pass phase one. First of all, it would take getting use to and in this day and age, many computer users are too afraid of change to subject themselves to anything new. Furthermore, who knows what kind of long term damages this could cause to the eyes of users, we're already going blind by staring at our computer screens all day, so don't push it.
