PROBLEM TO BE SOLVED: To determine a three-dimensional location of a user.SOLUTION: An information processing device includes: group classification means that classifies atmospheric pressure information measured from a plurality of users on a plurality of routes for a prescribed period into a plurality of groups on the basis of atmospheric pressure values; correspondence determination means that compares a relative relation between an atmospheric pressure value of one group of the classified groups and atmospheric pressure values of the other groups, with a relative relation between an altitude of one route of the plurality of routes and altitudes of the other routes to determine correspondence of each of the plurality of groups with each of the plurality of routes; acquisition means that acquires atmospheric pressure information for a user measured during moving at least any one of the plurality of routes; user classification means that classifies the acquired atmospheric information for the user into any of the plurality of groups on the basis of atmospheric pressure values; and route determination means that refers to the correspondence to determine the route corresponding to the classified group to be a route where the user moves. |
