Your limbs tire faster than your curious eye. It rolls on and on without even blinking sometimes. Hence we know that something like the Tobii PCEye technology can make using a PC, a lot less cumbersome and effortless. It follows your eye movements to action controls on your monitor, instead of a mouse or track pad that is generally quite a task. The PCEye is a USB device that mounts using VESA and hangs below 15 to 20-inch LCDs. Compatibility includes only Windows systems, after all the synchronization settings are in place.

There’s no price on the PCEye system as yet. But as soon as it’s out, I’m sure I’ll get hold of it’s awesome body-independent awesomeness.
