The Future of the User Interface?

Did you see Minority Report, the Steven Spielberg movie starring Tom Cruise (based on a short story by Philip K. Dick)?

The film features a futuristic computer user interface (UI) that intrigued viewers and suggested an entirely new way of interacting with computing devices. The story was set in 2054, but it turns out that the future is almost here.... See the film's science advisor, inventor John Underkoffler, present the current state of the art in a TED Talk posted on the I.S. homepage in iSITE.
