ZeroTouch to interface computers in open air
posted May 17 2011 20:22.08 by Giorgos Lazaridis

Meet the ZeroTouch, maybe the next generation "touch" screen interface. Designed by Texas A&M University, the ZeroTouch features a series of IR sensors at the internal perimeter of a parallelogram frame, 256 to be exact. The fingers will disrupt the IR beams from the 28 IR LEDs that are also at the internal perimeter of frame, and the sensors will sense the shade. Data are then transmitted to the host computer which can calculate the exact position of the finger. ZeroTouch can also detect more than one finger at a time. It is safe to label this gadget as Optical Multi-Touch Sensor.
