1. A method for enabling registration of a user to use a computer system, the method including: providing a printed registration form containing information relating to user registration, the form including coded data indicative of an identity of the form and of at least one reference point of the form; receiving, in a computer processing system associated with the computer system, indicating data from a sensing device regarding the identity of the form and at least one of a position and a movement of the sensing device relative to the form, the sensing device, when placed in an operative position relative to the form; and identifying, in the computer processing system and from the indicating data, at least one parameter relating to user registration, and storing the at least one parameter so as to be accessible by said computer system, wherein the sensing device comprises: (a) an image sensor adapted to capture images of at least some of the coded data when the sensing device is placed in an operative position relative to the form; and (b) a sensing device processor adapted to: (i) identify at least some of the coded data from one or more of the captured images; (ii) determine an orientation, within the captured images, of at least some of the coded data; (iii) decode at least some of the coded data; and (iv) generate the indicating data using at least some of the decoded coded data.
