The thrilling potential of 'SixthSense' technology

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.
