Sixth Sense Technology

Most of this had been seen already...but its worth watching everytime...Main person behind this is Pranav Mistry, a MIT graduate. He worked with Microsoft as a UX researcher. This is simply mind blowing,  An update from an earlier TED Talk  http://bit.ly/5mHZJ. Check out he made a piece of paper an interactive screen. One of the most Fascinating TED talks. More news on the Pranav's technology http://bit.ly/g0cGn , Best Part is he is going to make it opensource.

1. Camera: A webcam captures an object in view and tracks the user's hand gestures. It sends the data to the smart phone.
2. Colored Markers: Marking the user's fingers with red, yellow, green, and blue tape helps the webcam recognize gestures. Mistry is working on gesture-recognition algorithms that could eliminate the need for the markers.
3. Projector: A tiny LED projector displays data sent from the smart phone on any surface in view--object, wall, or person. Mistry hopes to start using laser projectors to increase the brightness.
4. Smart Phone: A Web-enabled smart phone in the user's pocket processes the video data, using vision algorithms to identify the object. Other software searches the Web and interprets the hand gestures.
