Researchers at the University of Groningen, in the Netherlands, have developed the world's largest, curved multi-touch screen. The screen, measuring 33 feet wide, incorporates 6 cameras and 16 infra red emitters to handle over 100 simultaneous touch points. But here's the coolest part ... it was created with nothing but off the shelf technologies.
The screen is powered by 3 computers which translate the digital information picked up by the cameras and IR emitters and provides for a total on screen resolution of 4900 x 1700 pixels. And all the parts were purchased off the shelf and incorporated with no proprietary or new technologies. The only thing created was the software written take take advantage of off the shelf technology.
