Why it’s cool: Forget the mouse, just look directly at whatever you want to manipulate on your screen. That’s the promise of Tobii’s eye-tracking technology. It won’t be affordable enough as a consumer product for a couple years but once it’s here, we may wonder how we ever lived without it. Try looking at something on your screen and then move your mouse cursor to the same spot. See how much faster your eyes move?
Availability: Medical use in about a year, consumer use about a year after that.
