摘要

A printed document is an interface with a computer. A camera generates a video signal representing an image of the printed document. A processor linked to the camera processes an image of the printed document and a finger or pointing implement pointing to a region of the printed document. The processor recognizes when a graphical user interface element within the captured image is selected by the user pointing to the user interface element on the printed document by determining the region on the page that is pointed to by the finger or pointing implement and determining from a memory the identity of the user interface element, if any, that corresponds to the region of the printed page pointed to by the finger or pointing implement and then triggers an operation represented by that graphical user interface element.
