SubscribeNokia researchers build huge touchscreen display made of ice
The hand movements of both gloved and ungloved users were tracked using rear-diffused illumination multi-touch tracking technology and an image of flames projected behind the moving hands in real-time
Article Summary
Researchers from the Nokia Research Center in Tampere, Finland, have turned a wall of ice into a huge interactive touchscreen display. Using infrared emitters and detectors to determine hand location and movement, the team projected images onto the blocks of ice so that users could see flames behind their hands. Happily, users didn't need to worry about catching a chill from icy fingers as the setup managed to keep track of gloved as well as ungloved hands.
