It's in the Eye's- Eye Control

It doesn't quite happen like the picture, but gesture control will be one of the big things for 2012 and included in that is controling devices with your eye movement. I don't mind the accelerated pace that devices seem to be evolving. I figure that controling a device with my eyes or other gestures is the closest that I will come to being like Stephen Hawkins (a.k.a. "The Hawk"). Expect this feature on everything from cellphones, to cars, to T.V.'s. Check out the lastest episode of The Quincey Technology Show to find out a little more about gesture control.
