After covering the tech world for more than a decade, I'm not easily amazed, but my jaw dropped when I saw the Tobbi Rex, a new peripheral for laptops that will let consumers control Windows 8 by tracking your eyes. You can scroll by looking up and down, and open an app just by staring at it and pressing a button. Another firm I met with, 4tiitoo, is working with Tobbi to develop middleware and applications that take advantage of eye-tracking technology. If you move your head to the left in a game, your character will move left.

But that's just the start. The company says it's looking to enable third parties to combine eye, gesture and voice control in popular apps like Photoshop. I put in a request for being able to pinch two fingers in the air to crop a photo and then saying "resize to 675 wide" to make it Web-friendly. That will save my team a lot of extra time at next year's CES.
