Researchers at Texas A&M University have created what may amount to one of the most important touch screen interface of our times: a screenless touch screen, literally. The ZeroTouch screen is an “empty” frame lined with LEDS and crisscrossed with infrared beams that can record where the beams are interrupted and the size of the touch area. Use it as a traditional drafting tablet, a painting canvas, etc.
