1. A method of enabling users to interact with computer software running in a computer system via:

  • an interface surface having disposed therein or thereon information relating to the computer software and coded data indicative of an identity of the interface surface and of at least one reference point of the interface surface, wherein the coded data is in invisible in the visible spectrum and wherein the information relating to the computer software is visible in the visible spectrum; and

    a sensing device comprising;

    (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 interface surface; and

    (b) a 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, using at least some of the decoded coded data, indicating data indicative of;

    the identity of the interface surface; and

    at least one of a position and a movement of the sensing device relative to the interface surface;

    the method including the steps of, in the computer system;

    (a) storing a page instance defining an association between the identity and a description of the interface surface;

    (b) providing at least the description and the identity to a printer;

    (c) controlling the printer to print the interface surface using the description and the identity provided to the printer, wherein the coded data is printed at the same time as the information;

    (d) receiving the indicating data from the sensing device operated by the user;

    (e) using the indicating data and the description to identify at least one interactive element relating to the computer software; and

    (f) operating the computer software in accordance with instructions associated with the at least one interactive element.
