1. An interactive system comprising:
(a) an article comprising a surface having a position-coding pattern printed thereon, said position-coding pattern identifying a plurality of positions on the surface and a surface identity at each of said positions; and
(b) a handheld sensing device having a housing, said housing containing: (i) an optical sensor for reading codes from the position-coding pattern (ii) a processor coupled to the optical sensor for determining a position of the sensing device and the surface identity using the read code (iii) a memory unit comprising data for different audio outputs corresponding to different positions on the surface, the memory unit coupled to the processor, and (iv) an audio output device coupled to the processor,
wherein said handheld sensing device is configured to provide the different audio outputs to a user in response to optically sensing different positions of the position-coding pattern, and wherein the surface identity distinguishes the surface from a plurality of other surfaces.
