The document describes the Sixth Sense technology, which allows users to interact with digital information using hand gestures. The Sixth Sense was developed by Pranav Mistry building off earlier work by Steve Mann. It consists of a camera, projector, and mirror worn around the neck that allows users to view and manipulate projected interfaces with natural hand motions. Some example applications described are viewing maps, taking pictures, and accessing information about objects in view. The potential for Sixth Sense is as a transparent interface for accessing any information in the environment.
