Abstract
A computer system programmed to run computer software for enabling user interaction with an interface surface, such as a sheet of paper bearing information relating to the computer software and coded data indicative of an interactive element relating to the computer software. A sensing device is placed in an operative position relative to the interface surface, and senses indicating data indicative of the interactive element. The sensing device also generates movement data indicative of the sensing device's movement relative to the interface surface. The indicating and movement data from the sensing device are received in a computer, and the interactive element identified. The computer software is then operated at least partly in reliance on the movement data, and in accordance with instructions associated with the interactive element.
