The following video was picked up from a Slashdot article. It displays a system that allows a user to control the interface on a screen without having to touch anything at all. The controller does not have attach devices to track coordinates either. Static electricity sensors pick up the coordinates and movements of the individuals' hand. Technology like this will trump motion sensitivity any day of the week because it makes the experience interactive, but takes away the need for external gadgetry and solicits a reaction without the need for touch. Pretty slick! Especially for those who are afraid of getting Swine Flu by using a touchscreen sign.
