Minority Report interface is one of the endgame dreams of Kinect hackers. We've seen plenty of brilliant Kinect hacks so far, but this latest one by members of the MIT Computer Science and Artificial Intelligence Laboratory is the closest thing we've seen to the dream.
The hack uses several components to distinguish fingers, allowing hand detection of 60,000 points at 30 frames a second. If you want to go down the rabbit hole of techno-babble gobbledygook (yes, it's a scientific term), you can go here. For those who just want to see something cool, go past the break.
