‘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.

Students at the MIT Media Lab have developed a wearable computing system that turns any surface into an interactive display screen. The wearer can summon virtual gadgets and internet data at will, then dispel them like smoke when they’re done.
Watch video of student Pranav Mistry who is described as the brains behind the project. Mistry wears the device on a lanyard around his neck, with coloured Magic Marker caps on four fingers (red, blue, green and yellow) which helps the camera distinguish the four fingers and recognise his hand gestures with software that he created.
