A team at Nokia in Finland has created one of the unlikeliest computer displays yet – the world’s first ice touchscreen.
The team made their wall an interactive one by using digital projection technology, rather than peppering the ice with sensors that would raise the cost of the installation, Virolainen told the Interactive Tabletops and Surfaces conference in Saarbrücken, Germany, last week. The icescreen uses rear-diffused illumination (RDI), a technique first used by Microsoft in its table-based interactive touchscreen, Surface, launched in 2008.
