“Reality Touchscreen” Is 10 Meters Long, Accepts 100 Touch Inputs
Students at the University of Groningen in the Netherlands have created a “Reality Touch Screen,” a 10 meter long touchscreen that accepts up to 100 multitouch inputs at a time. As we see from this short video, the effects they’ve been able to create are wild and the sensitivity looks great.
Behind the long screen are six cameras and 16 infrared lights. When you touch the screen, a small amount of infrared light is reflected back and the cameras sense the position and then translate that into coordinates on the surface. It is curved over 135 degrees, thereby creating an immersive environment.
