Cool stuff: Perceptive Pixel’s 82-inch multi-touch touchscreen display

Jeff Han, the CEO of Perceptive Pixel, is one of the pioneers of touchscreen displays, having gone public with his touchscreen display technology a year before Apple launched the iPhone in 2007. Now his company has unveiled an 82-inch multitouch touchscreen display that can recognize both finger touches and a stylus. With it, you can put your hand on the display and write on it with the other hand with a stylus, as if you were writing on a piece of paper.
