They use basic technology tools - a camera, a mirror, a rechargeable battery, pointers and a cellphone (for communication) to bring to life possibilities that bring the entire world literally on your finger tips. In the team's words, SixthSense 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.Its more than QR Codes, Microsoft Surface, iPhone, a digital personal assistant. All put together. Wish it comes to life soon. And this is what I can the New New Thing.
