1. A method of enabling user interaction with computer software running in a computer system via:

  • a first interface surface containing information relating to the computer software and including a plurality of first tags, each first tag containing first coded data indicative of an identity of the first interface surface and a location of the tag on the first interface surface; and

    a sensing device which, when placed in an operative position relative to the first, interface surface, uses at least some of the first coded data to generate indicating data indicative of;

    the identity of the first interface surface; and

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

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

    (a) receiving the indicating data from the sensing device when placed in an operative position relative to a first interface surface;

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

    (c) operating the computer software in accordance with instructions associated with the at least one interactive element, and(d) instructing a printer to print a second interface surface representing output of the computer software operating in accordance with the instructions, said second interface surface including a plurality of second tags, each second tag containing second coded data indicative of an identity of the second interface surface and of a location of the tag on the second interface surface;

    wherein the sensing device is further adapted to store a sensing device identifier which is adapted to distinguish the sensing device from other sensing devices of the same type.
