"Student Scott Sullivan, in a talk called "The Horizon of the Human Interface," discussed new hardware to let us interact with our computers. We are reaching the limits of the capabilities of keyboards and mice, Sullivan said, brandishing a Nintendo Wiimote.

"The Wiimote, he said, has three accelerometers, allowing it to recognise relative movement in space. It is also equipped with a relatively high-performance infrared camera and Bluetooth, sells for about $45, and has been fully reverse-engineered. "There are oodles of drivers for it," he said, some in X, and he made the point by changing to the next slide in his presentation by pressing a button on his Wiimote.

"Sullivan briefly touched on the latest touch-screen technology, describing something called FTIR -- Frustrated Total Internal Reflection. Current touch-screens, he said, allow only one input at a time. FTIR touch-screens work differently, and allow an infinite number of inputs at a given time. The technology operates simply, he explained, by employing a piece of plexiglass with LEDs around its edge pointed inward. An image is projected on it from behind. The light from the LEDs reflects around inside the pane of plexiglass, and when someone makes contact with it, it breaks that reflection and the input can be read from an optical sensor out near the projector."
