Students at Northeastern University in Boston have created an interactive interface that harnesses electrostatics to give you 3D control just by waving your hand in front of a computer. No camera, no markers, no physical controllers: it recognizes xyz coordinates, and even works with modeling and music programs. As you move your hand in three-dimensional space, the information is transmitted to the computer.
Peter Kirn of Create Digital Motion contacted a member of the student team, Justin Schunick, to learn more. Per Justin: "The interface uses an array of copper electrodes to sense a certain change in the electric field created by the device. The black material covering the electrodes shows how the interface can be hidden beneath surfaces to create a completely invisible interface. It is simple black felt you can buy at any fabric store. The total cost of this prototype was around $60.00 USD."
Speaking for myself, and considering my fitness level after nearly 2 1/2 years of participating in virtual worlds, I would welcome any technology that encourages whole body movement while working in 3D environments.
