From the TED (Technology, Entertainment , Design) site:
This demo — from Pattie Maes’ lab at MIT, spearheaded by Pranav Mistry — was the buzz of TED. It’s a wearable device with a projector that paves the way for profound interaction with our environment.
Pranav Mistry is the genius behind Sixth Sense, a wearable device that enables new interactions between the real world and the world of data.
