The University of Groningen in the Netherlands made this 32.8 ft. by 9.2 ft. touchscreen interface from six expensive cameras… and some “cheap” infrared emitters, 1000 LEDs, some old computers that were sitting around, and some free software.

The result is a positively enormous curved screen with a resolution of 4900 by 1700 that can track 100 different touches at a time… and that’s just at optimum speeds.  Latency is between 30 and 50 ms.

Anyone up for a game of Pong?

(Ignore the last minute of video. It’s just black. There’s no stinger. We were confused, too.)
