You'd think the FBI, CIA, Interpol or some other government agency would be home to the world's largest touchscreen right? You'd be dead wrong. The world's largest touchscreen resides at the University of Groningen in the the Netherlands and isn't used to catch world criminals, but to teach math and computer science.
With a curvature of 135-degrees and measuring at 32.8 feet long by 9.2 feet high, the entire screen could swallow you whole while you input those top-secret algorithms you've been working on day and night.
For the geekier geeks, knowing that the screen is transparent, uses 6 Optitrack cameras, 1000 infrared LEDs, has a 4900 x 1700 resolution, has 120 Hz stereo and has 50 ms of latency will probably make you spit your morning coffee out.
As you can see in the video, three demonstrators are interacting at once with the touchscreen, swirling pixels, doodling things and moving windows just like a gigantic Microsoft Surface table — only the touchscreen is on the wall. With the touchscreen capable of reading up to 100 touch points simultaneously (that's 10 people using hands), we'd say those math and computer science classes must be incredibly fun. LINK
