The document describes the Sixth Sense technology, which integrates digital information into the physical world. It consists of a camera, projector, mirror, mobile computing device, and colored markers. The camera tracks hand gestures while the projector displays information on surfaces. The mobile device processes data from the camera and projects using a mirror. Applications include making calls, maps, time, photos, drawings, and accessing information about objects. Advantages are portability, multi-touch interaction, connecting the physical world to information, cost-effectiveness, and idea mapping anywhere. In conclusion, it allows natural gesture interaction with any information from the environment.
