John Underkoffler designed the futuristic computer interface that was shown in the 2002 movie Minority Report, and in 2006 he founded Oblong Industries to make the interface real. Bright Side of News came across a two-part video that shows off Oblong's progress:
But perhaps the most impressive part of the movie was the computer interface used by Tom Cruise. If you have followed this closely, you'd probably know that the technology itself wasn't special effect but rather combined rather exotic materials, such as holographic projectors (reverse Black UV projector), special sheets of material and touch sensors within gloves.
Recently, a video came out that went into greater detail how the interface actually works, and if you have a fat checkbook, you can actually turn a movie into a reality. If you have time, dedicate next hour and watch the video about the Mezzanine interface with its creator, Oblong Industries.
