Take everything you thought you knew about multitouch and throw it out. Okay, keep the Minority Report stuff, but throw everything else out. What we're looking at here is a 22 megapixel display, stitched together from the output of no less than 28 projectors (7,168 x 3,072 total resolution), which just happens to respond to touch-like input in a fashion even Tom Cruise would find fascinating. You don't have to actually touch the wall, floor-mounted cameras pick up your gestures in 2D space and a 30-node computer setup crunches all the computational and visual data to deliver some buttery smooth user interaction. For demo purposes, the makers of this system grabbed a 13.3 gigapixel image of Tromso and took it for a hand-controlled spin. See the mesmerizing show on video after the break.
