In Groningen, The Netherlands sits the University of Groningen's Reality Touch Theatre which at 10 meters (33 feet) wide is called the biggest touchscreen interface in the world.
The university has converted its existing cylindrical 3D theatre into a touchscreen that can detect more than 100 touch interactions at any one time.
