The University of Groningen, in the Netherlands, has converted a 3D theater into the world's largest touchscreen, used for teaching mathematics and computer science students interactivity. The screen has a curvature of 135 degrees and is transparent. Continue past the break to see the video and find out exactly how large this screen is.
The screen measures 10 meters by 2.8 meters (or 32.8 feet by 9.2 feet for those of you who are metrically challenged like me) and can detect up to 100 simultaneous touch inputs. The screen uses infrared LEDs and 6 Optitrack cameras to detect touch.
Here are the specs:
- 6 Optitrack cameras
- 1000 infrared LEDs
- 4900 x 1700 Pixels
- 120 Hz stereo capability
- 50 ms latency
