The inFORM Dynamic Shape Display from MIT's Tangible Media Group allows users to interact with data with a minimum of physical barriers. It also allows users to virtually reach through a display screen, and manipulate physical objects that may be thousands of miles away. While the current version of inFORM has very limited spatial resolution, watching it in action gives one a strong impression of the potential of such devices.
The most important part of an inFORM isn't the 3D display itself. Rather, it is the coupling of a Kinect sensor and projector to extract 3D input from "watching" the movements of a user's hands. The position of a fingertip can be established to within about 2 mm (0.08 in) in the horizontal plane, and to about 1 cm (0.4 in) in height above the plane.
