Touchscreen Table

CNN reports that Mitsubishi's new DiamondTouch is a PC screen on a tabletop. People sit around it in specially equipped chairs and use their fingers to create and manipulate "objects" with the help of touch sensors embedded in the tabletop panel. Small electrical currents flow through the chairs and communicate with the panel, making clear whose fingers are making which changes.
