- The sixth sense technology allows users to interact with digital information by using hand gestures without any hardware devices. It was first developed in 1990 as a wearable computer and camera system.
- The key components are a camera to track hand gestures, a projector to display information onto surfaces, and a mobile device to handle internet connectivity. The camera sends gesture data to the mobile device for processing using computer vision techniques.
- Applications include using hand gestures to draw on surfaces, get flight information by making circular gestures, and make calls by typing on an projected keypad. The technology aims to seamlessly connect the physical and digital world.
