1. Apparatus for controlling an interactive display device, comprising;
- a surface on to which an image produced by a processor means may be projected, said surface comprising an optically discernable pattern or ornament, said pattern or ornament having encoded characteristics capable of providing unique positional reference information and/or control information in respect of positions on said surface;
a sensor means, said sensor means being configured to capture said unique positional reference and/or control information relating to its position in relation to said optically discernable pattern or ornament on said surface, and to transmit said respective positional reference information to a processor means;
a processor means, said processor means being operable to receive said positional reference and/or control information from said sensor means;
said processor means being operable to associate said positional reference and/or control information with functions relating to at least one computer program operable in said processor means.

Abstract
An interactive display system comprising a position coded pattern that is printed on a display surface. An electronic pen is equipped with a decoding real-time processor; the decoding of the surface pattern reveal sets of predetermined (x, y) coordinates embedded within the pattern. A real-time processor works simultaneously to decode (x, y) coordinates while these are sent immediately via wireless communication to a host PC which is normally attached to a projecting device.

12. A computer program stored in a computer readable medium for controlling an interactive display device, said computer program product comprising;
-
instructions for controlling an interactive display device, said instructions comprising; instructions causing a processor to receive at least one input in the form of positional reference and/or control information in relation to the position of a sensor device to a display surface, said display surface comprising an optically discernable pattern or ornament onto which an image controlled by said processor may be displayed; instructions to perform a specific processor action or function based on the said at least one positional reference and/or control input so received.
