Inspired by the success of our AIRTouch project, Fraser and I wanted to adapt the multi-touch activities that I created for the AIRTouch system to a much larger surface. We used our large rear-projected “Disney” screen, a Wiimote, an off-the-shelf NEC projector, an inexpensive Bluetooth dongle (Deal Extreme is awesome), and a custom IR ‘light pen’ to make our AIRWall system. We initially used Johnny Chung Lee’s Wiimote software (he is the nicest guy) to handle the tracking of the IR ‘light pen’, and then later built our own.
