Patent ID: 7456820

Claim:
A method of enabling user interaction with computer software running in a computer system via: an interface surface containing information relating to the computer software and a drawing input field and having disposed therein or thereon coded data at least partially indicative of the drawing input field; and a sensing device which, when placed in an operative position relative to the interface surface, senses at least some of the coded data and uses the sensed coded data to generates indicating data at least partially indicative of the drawing field, and generates movement data indicative of the sensing device's movement relative to the interface surface; the method including the steps of, in the computer system: (a) receiving the indicating data from the sensing device; (b) receiving the movement data from the sensing device, at least part of said movement data representing drawing input by the user; (c) identifying the drawing input field at least partially from the indicating data; and (d) operating the computer software at least partly in reliance on the drawing input, and in accordance with instructions associated with the drawing input field.
