Patent ID: 7002559

Claim:
A method of managing information input via a sensor device and a position-coding pattern printed on a product, comprising: reading coordinates of said sensor device based on movement of said sensor device relative to said position-coding pattern, said position-coding pattern including marks that code coordinates on a reference surface, said reference surface including position-coding pattern portions that are used to create a plurality of product types, said position-coding pattern printed on said product including at least a first sub-pattern portion and a second sub-pattern portion; and executing an information management function based on coordinates read from said first sub-pattern portion, said information management function managing information formed by coordinates read from said second sub-pattern portion, wherein said sensor device determines a characteristic of at least one of said first sub-pattern portion and said second sub-pattern portion based on at least one coordinate read from said product and definition data stored in a memory of said sensor device, wherein coordinates read from said product define multiple bit codes and said sensor device determines a local coordinate within said second sub-pattern portion based on said definition data and at least a portion of a multiple bit code.
