Mitsubishi's DiamondTouch displays a PC screen on a high-tech tabletop. People sitting around it use their fingers to create and manipulate projected virtual objects, with the system knowing whose fingers did what thanks to small currents of electricity that flow through the chairs.
Masakazu Furuichi, chief engineer at the Japanese electronics maker, hopes DiamondTouch will become a tool for games, and other areas in which several people need to interact intuitively and instantly.
But first the price will have to drop -- the tables can cost as much as $10,000 each.
"It's a futuristic way to use a computer without a keyboard or a mouse," Furuichi said. "It's simple to use for everybody, including older people and others who aren't very used to handling computers."
