What do you get when you combine a mobile phone, a camera, a little projector, some markers on your finger tips and a mirror? The god-dam Minority Report future is what. And it's called SixthSense.
http://www.ted.com/talks/view/id/685It's a 13 min video but you can skip to the 4 minute mark, but it's well worth watching.
Basically it's a system where information is projected onto any surface, and surfaces can be read from for information. Nothing new technology wise, but it's the merging together which is the impressive part. At the moment it uses off the shelf components which they said cost around $350 and they plan to make it open source. Really just watch the video and see the possibilities.
It makes me happy that they are people working on this sort of stuff.
