Patent ID: 7518756

Claim:
A method of delivering a facsimile, including: providing a first printed form having a plurality of first location-indicating tags printed thereon, each first tag containing coded data indicative of the tag's unique location on the first form and an identity of the first form; writing a message on the form using an optically imaging pen having a marking nib, said pen imaging at least some of said tags when writing said message; computing positions of the nib from an inferred multiple degree-of-freedom perspective transform of the imaged tags and a known geometry of pen optics; transmitting, to a computer system, a series of digital ink strokes, each stroke comprising indicating data derived from tags imaged by said pen, said indicating data comprising data regarding the identity of the form and positions of the nib relative to the form in order to allow the message to be electronically captured in the computer system, thereby enabling the computer system to transmit the message to a designated recipient address for facsimile delivery.
