Sixth sense technology is a wearable gesture interface that uses natural hand gestures to interact with the digital world. It consists of a camera, projector, and mirror coupled in a pendant-like mobile wearable device. The camera recognizes individuals, images, and gestures, and sends the information to a connected smartphone for processing. The projector then projects the output image onto the mirror, which reflects it onto the desired surface. Some applications of sixth sense technology include taking photos with gestures, getting information about books or people by projecting it, making calls by projecting a virtual keypad, and more.
