Nokia Researchers Create A Touch-Screen On Blocks of Ice
Using a simple process, natural materials are made interactive.
Nokia researchers in Tampere, Finland have created an interactive touch-screen on blocks of ice. After smoothing the surface with a heat gun, they projected infra-red light onto the ice so that when the surface is touched by human hands the light is reflected back from them and colors appear on the ice. A computer then tracks and follows the movement to create a stunning effect.
