The stand-out piece of technology from the movie is undoubtedly the gesture interface that's used to interact with the "Precrime" system central to the film (more on that later). In an interview with Salon shortly after the film's release, another one of those aforementioned advisers, John Underkoffler, said that Spielberg had one direction for this particular bit of tech. He wanted someone using the interface to look like a person conducting an orchestra (a notion that would be echoed by the film's score when we see the technology being used). Underkoffler took that idea and ran with it, drawing on work done by himself and others at MIT for further inspiration.
