Sixth Sense is a wearable device that allows users to access digital information by interacting with the physical world through natural hand gestures. The device consists of a camera, projector, mirror, and smartphone. It captures gestures and images from the camera and projects information back onto physical surfaces through the projector. Some applications include making calls, accessing maps, taking photos, and drawing. The system provides an intuitive way to access information without traditional interfaces like keyboards or mice.
