Fraunhofer-Gesellschaft have developed the iPoint 3D, a technology that enables us to interact with a 3D display via simple gestures -- all without touching the panel and without 3D glasses. The heart of iPoint 3D is a recognition device, not much larger than a keyboard, that can be suspended from the ceiling above the user or integrated in a coffee table. Its two built-in cameras detect hands and fingers in real time and transmit the information to a computer.
