Forget just watching Minority Report. Why not build an interface just like it for yourself?
Kyle McDonald, a media artist and guest researcher in residence at the Yamaguchi Center for Arts in Japan, was responsible for the first implementation of this Touchless 3D Tracking Interface. According to his project page on Instructables, the basic goal was to create a "3D hand-position sensing system that most people can build, while preserving some semblance of functionality."
Sounds fancy, huh? I agree. Surprisingly, it doesn't require much in terms of material. The Touchless 3D Tracking Interface is essentially a bunch of cardboard panels lined with aluminum foil, an Arduino microcontroller, some code, and an absolutely ingenious understanding of electric fields.
If you're interested in coming up with your own homegrown alternative to modern-day motion-sensing peripherals, you should probably check out the Make Magazine's take on the subject. It's a little easier to understand and, if McDonald's any judge of things, slightly more up-to-date. That said, regardless of which set of instructions you follow, this actually looks like the sort of thing anyone with even a passing aptitude for craftsmanship would be able to achieve.
If this is what they call an introductory project at Make Magazine, I wouldn't be surprised if someone told me the experts were busy making Gundams in their free time.
Now, tell us if you end making Minority Report a reality, okay?
