This Giant Touchscreen is World's Largest Touchscreen
The University of Groningen, in the Netherlands, has converted a 3D theater into the world’s largest touchscreen, used for teaching mathematics and computer science students interactivity. The screen has a curvature of 135 degrees and is transparent.
It can handle over 100 touch points at the same time. One of the great things about this touchscreen is that it doesn’t rely on any fancy new technology. It was basically put together with some PCs, video cameras, projectors and cheap infrared illuminators.
