This is the result of a quick program created at Second Story Interactive Studios to determine if a multitouch user interface could be created using a capacitive surface. No lights, cameras or digitizers were used to make the surface interactive. Instead, we used a small "Vip Foil" from a company called Visual Planet. The capacitive film is located directly under the table surface shown. The capacitive film is transparent, so it could just as easily be adhered to a window or other clear surface. Because it uses projected capacitive technology, it can sense range (how close your hand is to the surface) in addition to position.

Although the interactive area shown in this demo is relatively small, the same technology can be purchased in sizes measuring up to 116 inches diagonally to make a fairly large multitouch surface.
