This document discusses the Sixth Sense technology, which is a wearable gestural interface that projects digital information onto physical surfaces using a camera, projector, and mirror. It recognizes hand gestures to interact with projected apps for making calls, using maps, getting information about products, books, and people. The advantages are natural interactions using gestures and accessing contextual information. It has applications in photography, reading, drawing and accessing travel updates. The conclusion is that it allows accessing digital information in any way using gestures and has potential as a transparent interface.
