| 1. A method for enabling registration of a user to use a computer system, said method comprising the steps of:
providing a printed registration form containing information relating to user registration, the form including a plurality
of tags, each tag containing coded data indicative of an identity of the form and of a position of the tag on the form,
positioning a nib of an optically imaging pen in an operative position relative to the form;
sensing at least some of the coded data contained in a tag;
computing a position of the nib from an observed perspective distortion on an imaged tag and a known geometry of pen optics;
generating indicating data using at least some of the sensed coded data, said indicating data comprising data regarding the
identity of the form and data regarding a position of the nib relative to the form;
sending, to a processing system associated with the computer system, the indicating data and a pen identifier,
thereby enabling the processing system to identify, using the pen identifier and the indicating data, at least one parameter
relating to user registration, and store the at least one parameter so as to be accessible by said computer system,
wherein the pen electronically stores the pen identifier in a read-only memory in the pen, the pen identifier distinguishing
the pen from other pens of the same type.
