The University of Groningen have created a huge screen and added touch detection to it using six Optitrack v120 slim camera’s due to their sensitivity for infrared light, 16 cheap infrared emitters the ones used for security systems, together with a total of 1000 LED’s.
The touch detection software has been installed on three old computer systems each fitted with two camera’s. One extra computer is then used to combine the output from the detection computers and send the event data to the main visualisation system. Watch the video after the jump to see it all in action.
The massive curved display is constructed from a 3 mm dark acrylic layer, which is then coated with a diffuser on the front. Illumination is situated behind the display using six full hd projectors and the cameras and the ir-leds are also located behind the screen providing a clean clutter free working environment at the front. More information about the display and touch system can be found here.
