摘要

PROBLEM TO BE SOLVED: To provide a zone determining apparatus capable of automatically varying a zone setting in response to an element dynamically changed and to provide a zone determining method, a program for making full use of a zone determining function, and an information recording medium for recording the program for making full use of the zone determining function.;SOLUTION: The zone determining apparatus is characterized in to include: position acquisition means 11h, 43 for acquiring position information with respect to a present location; a zone setting means 49 for setting a zone Z of a polygonal shape in response to a dynamic change in at least one element being a component of the zone Z; and zone discriminating means 45, 49 for determining whether or not the apparatus itself exists in the zone Z on the basis of the set zone.;COPYRIGHT: (C)2004,JPO&NCIPI
