Grad students at University of Tromsø in Norway constructed a 22-megapixel touch screen for viewing gigapixel photographs.
The screen is made of 28 1024x768 projectors, synchronized by 30 computers that determine which projector should show which portion of the image.
Watch the video at www.cs.uit.no/~daniels/gigapix to see the touch screen in action; it even responds to sounds, like snapping fingers to zoom in.
This project by Tor-Magne Stien Hagen, Daniel Stødle, and Otto J. Anshus was meant to overcome the problem of viewing gigapixel photographs on our "tiny" 2-megapixel desktop monitors. Using a high-resolution, large format display overcomes the problem, say the grad students. But those of us who work with vector graphics don't have the problem, since we don't need gigapixel-resolution source images for detailed CAD drawings.
