Cooler touch screen than the iPad or iPhone? Nokia Research Lab and the world's first Ice Touch Screen
So we’ve seen how Nokia can turn any screen into a touch screen. What about something that’s not even a screen to begin with – what about a block of ice? That’s exactly what’s been occurring in Tampere, Finland at Nokia’s Research Lab.
Check it out in the video from New Scientist (cheers dsmobile for the heads up!)
“This was a playful experiment, but one that we think showed interactive computing interfaces can now be built anywhere,” Jyri Huopaniemi, Nokia.
How does it work?
Like Microsoft surface, this uses a technique called rear-diffused illumination. Infra-red light (or pretty much) is beamed behind the ice screen and placing a hand in front of the ice reflects that light back towards a camera which in turn helps a computer to calculate the hand position and thus direct a projected image near the hand.
