Computing merging with the physical world. Amazing thought provoking ideas. Enjoy!

Pranav Mistry is part of the MIT Media Lab and is a PhD student and inventor of Sixth Sense. Sixth Sense is a "wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information."

A couple of examples include using your hands to frame and take a picture, to then stop at any surface or wall and flick through the photos you've taken. Other uses include augmenting physical objects, such as displaying live information on a newspaper, or adding dynamic digital information to a book you are looking at in a bookstore. He also has talked about this technology being used to help someone who cannot speak to more easily interact with the world.

This is all open-source. 

He recently spoke at TEDIndia -
