Wearable gestural interface

This invention may be implemented as a wearable apparatus comprised of a camera, a projector, a mirror, a microphone and a digital computer. The camera captures visual data. This data is analyzed by the digital computer to recognize objects and hand gestures, using color tracking and edge detection techniques. The projector is used, along with a mirror to adjust the direction of the projected light, to project images on objects in the user's environment. For example, the images may be projected on surfaces such as a wall, table, or piece of paper. The projected images may contain information relevant to the object being augmented. Indeed, the information may include current data obtained from the Internet. Also, the projected images may comprise graphical interfaces, with which a user may interact by making hand gestures.
