A method and system for enabling user interaction with computer software running in a computer system. A user is provided with an interface surface containing information relating to the computer software and including coded data indicative of an identity of the interface surface and of at least one reference point of the interface surface. The user places a sensing device into an operative position relative to the interface surface. In this operative position, the sensing device senses indicating data indicative of: the identity of the interface surface; and a position of the sensing device relative to the interface surface, using at least some of the coded data. The computer system receives the indicating data from the sensing device, and uses the indicating data to identify at least one interactive element relating to the computer software. The computer software is then operated in accordance with instructions associated with the at least one interactive element.
