The document describes Sixth Sense technology, a wearable gestural interface developed by Pranav Mistry that augments the physical world with digital information. It consists of a camera, projector and mirror worn around the neck connected to a smartphone. The camera tracks hand gestures marked with colored markers to interact with projected interfaces on surfaces. Applications include making calls, maps, photos. Benefits are an intuitive interface and turning any surface into a display. Future enhancements could remove markers and incorporate the technology into mobile devices and applications like education and gaming.
