A technique for automatically controlling a computer by the remote (or proximal or local) scanning of special coded-indicia to execute computer-stored programs directly and automatically in response to computer-translated instructions represented by the scanned coded indicia, such as the presentation of specified supplemental pictorial and other website stored materials to the reader of a book or magazine or the like containing such coded indicia keyed to said website, and more generally, to cause the computer automatically to execute desired programs in direct response to such coded indicia scanning.
