Abstract
A method for hierarchical management of a plurality of regions of an encoded surface. The method includes recognizing unique encoded information on a portion of the surface in response to a pen computer touching down on the portion. A unique location of the portion of the surface is determined based on the unique encoded information. A region is determined out of the plurality of regions for the location. Upon the determination of the region, a determination is made as to whether the location is within a sub-region within the region. If the location is within a sub-region, a function of the pen computer is performed based on the sub-region. If the location is not within a sub-region, a function of the pen computer is performed based on the region.
