In this note, we present SixthSense, a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. By using a tiny projector and a camera coupled in a pendant like mobile wearable device, SixthSense sees what the user sees and visually augments surfaces, walls or physical objects the user is interacting with; turning them into just-in-time information interfaces. SixthSense attempts to free information from its confines by seamlessly integrating it with the physical world.
