Latest SixthSense demo features paper 'laptop,' camera gestures

We've already seen MIT researcher Pranav Mistry's SixthSense projector-based augmented-reality system in some cool demos, but he just gave a TED talk and his latest ideas are the wildest yet. Forget simple projections, he's moved on to taking photos by just making a box with your fingers, identifying books and products on store shelves and projecting reviews and other information on them, projecting flight schedules on boarding passes, and even a new paper "laptop" concept that works by using a microphone on the paper to sense when you're touching it. It's pretty amazing stuff -- check out his whole talk at the read link.
