BOFFINS BEHIND the Minority Report flick have come up with a real life interface which mimics that used in the movie.
Dubbed G-Speak, its inventors – who advised Steven Spielberg during the movie – claim it is the first major improvement in the computer interface since 1984.
The inventors say that the interface combines "gestural i/o, recombinant networking, and real-world pixels."
It basically "consists of an off-the-shelf DLP projector and special gloves embedded with reflective beads."
It requires a really costly infrared camera to work and a lot of room to operate but it's pretty impressive. Follow the L'Inq for video and more details.

But will it play Doom 3?
