Abstract

A system for sending an e-mail message. The system comprises comprising a printed form having a plurality of location-indicating tags printed thereon. Each tag contains coded data identifying a location of the tag on the form and an identity of the form. The system further comprises an optically imaging pen for writing a message on the form. The pen comprises a marking nib for writing a handwritten message on the form, an image sensor for imaging the tags when writing the message on the form, and a processor for computing positions of the nib using the coded data contained in the imaged tags, an inferred multiple degree-of-freedom perspective transform of the imaged tags and a known geometry of pen optics. A computer system receives indicating data generated by the processor and initiates sending of the e-mail message to a designated recipient address.
