Sixth Sense is a wearable technology developed by Pranav Mistry that allows users to access digital information by using hand gestures. It consists of a camera, projector, and mirror connected to a smartphone. The camera tracks hand gestures with color markers on the fingers and sends the data to the smartphone for processing. The smartphone then sends information to the projector, which projects the data onto the mirror and surfaces around the user. Some applications include getting the time by drawing a circle on the wrist, projecting maps and making calls. The technology aims to augment the physical world with digital information accessible through natural hand gestures.
