Abstract:
1. A method of enabling user interaction with computer software via: an interface surface containing information relating to at least one drawing field and to the computer software and having disposed therein or thereon coded data, the coded data comprising a plurality of undifferentiated marks positioned relative to a predetermined pattern, each mark having a plurality of possible values, and the coded data being at least partially indicative of an identity of the interface surface and a plurality of reference points of the interface surface; 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, using the sensed coded data: generates indicating data indicative of the identity of the surface; generates at least one of movement data indicative of the sensing device's movement relative to the interface surface and, position data indicative of the sensing device's position 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 at least one of the movement data and the position data from the sensing device; (c) identifying the at least one drawing field from the indicating data; and (d) operating the computer software at least partly in reliance on the at least one of the movement data and the position data, and in accordance with instructions associated with the at least one drawing field.
