The worlds largest touch screen in Groningen

In the university of Groningen, the Netherlands students developed the worlds largest curved touch screen!
They used six Optitrack v120 slim camera's which have a good sensitivity for infrared light. They used 16 cheap infrared emitters (the kind used for security systems) with a total of 1000 LED's.
The touch detection software runs on three old computers each with two camera's connected. One extra computer combines the output from the detection computers and send event data to our main visualization system.
This way they have (even using the old computers) enough processing power to be able to run the detection software at 60Hz and with a latency between 30 ms and 50 ms. It can detect without any problem 100 different touches at any time..according to the students.
All these technical information sounds a little blur to me, but watching the movie makes me feel very excited and proud to be Dutch!
