A touch-sensitive gadget with the sensing panel on its back, instead of the screen, is being developed by US researchers. Using your fingers behind the device allows a firmer grip and more accurate performance without obscuring your view of the screen. When the user touches the interface on the back, an image of a finger appears behind the icons on the screen and moves around in sync with the user's finger, almost as if the device were transparent. A small active spot marked on the finger's end is used to interact with buttons onscreen. To complete the illusion, the fingertip turns white as if pressed against a sheet of glass when the user presses on the touchpad.
