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.
