Networked computer system with wireless pen interface

摘要

A networked computer system includes a printer configured to print media bearing visible graphic data and invisible coded data tags and receive transmitted sensed data associated with the data tags. A pen-type device includes an image sensor configured to sense the data tags and wirelessly transmit associated sensed data to the printer. One or more servers are interfaced to the printer, via a network, and are configured to receive the sensed data from the printer and process the sensed data.
