Researchers Present Touch Screen Sans Screen
Researchers from Texas A&M University recently unveiled a new type of touchscreen that does away with the physical screen during the Computer Human Interaction conference held in Vancouver, B.C.
ZeroTouch uses a grid of infrared light to detect when an object passes through the picture frame-like device, detecting not only position but also the size an movement of the object in question, allowing it to differentiate between a human finger and the twisting brush of a painter. ZeroTouch is also capable of detecting up to 20 different touch-points at the same time, opening up a whole realm of creative collaboration possibilities.
Artistic applications are some of the first to spring to mind when considering the possibilities of ZeroTouch, allowing any flat surface to become a sketch pad or canvas. The team is already looking at stacking several of the devices, allowing them to create a true sense of depth and opening more doors for new 3D applications.
