Funny too

You must have read about 28-year-old Indian-born Pranav Mistry’s digital prototype called the “sixth sense“, which a wearable hi-tech device that can turn anything into a touchscreen. Your wrist can become a watch and your palm a phone. The device is combination of a wearable camera, a projector and a mirror where the camera recognises movements of the fingers of your hand and translates those into commands. For instance, when you pick up a product at a grocery store, the device can wireslessly search for comparative prices, degrees of recyclability, etc.

See Video

You pick a book up at a store and the device can search and display reader reviews and ratings. You can make the familiar gesture that cinematographers and photographers do–of making a frame with both your hands–and click a photograph. Mistry (and his mentor Pattie Maes of the MIT Media Lab) demonstrated the “sixth sense” last month at T.E.D. Watch the video to see just how amazing this new technology is. True, it’s still some way off from becoming a commercial launch, but “sixth sense” can change the way we live and seek out information or even entertainment.
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. Imagine "Minority Report" and then some.
