Abstract
A method of retrieving and manipulating electronic information that relates to a printed document. Each printed document contains an initialization marking that is recognizable by an external sensory device and unique to the printed document. When a reader of the printed document desires to retrieve and manipulate electronic information that relates to the printed document, the reader initializes the system by using the sensory device to recognize the initialization marking. The sensory device transfers a code embedded in the initialization marking to a computing device. This configures the computing device to access the stored data and instruction sets associated with the printed document. In addition to the initialization marking, areas throughout the printed document (e.g., text, tables, figures, etc.) also contain markings that are recognizable by the external sensory device. The reader of the printed document uses the sensory device to recognize the markings and transfer the code embedded in the markings to the computing device. The computing device uses the code to retrieve and display the electronic information that relates to that area of the printed document.
