The computer from the film Minority Report now looks like it could soon become a reality following the development of a new device called Sixth Sense created by the fluid interfaces research group at the Massachusetts Institute of Technology.

In the film Tom Cruise manipulates information on a giant computer screen using hand gestures. Sixth Sense is a device that you wear around your neck that contains a small projector and webcam.
The pendant communicates either with a laptop in a backpack or a smartphone connected to a remote server. The webcam monitors the user's hand gestures and conveys them to control software running on the laptop or server.
This then displays information on any surface and can be manipulated with hand gestures. This software uses the projector to initially display a menu. The user taps on an icon, and this gesture is relayed to the software, which opens the selected application.
This could be something like a map displayed on the surface, which the user can then control with a wave of their hand.
