A while ago I wrote about Jeff Han’s multi-touch interface and of course it got a lot of attention off the back of the iphone’s similar interface.
Han since spun off a company called Perceptive Pixel and below is the latest version of his multi-touch interface. It’s much bigger and, more impressively, it can handle two people working on it at once. Again, I still wonder what computing power is behind this and how expensive it all is, but you can imagine some very interesting collaborative processes happening. He needs to let some children loose on it too.
