Kind Code:
A1
Abstract:
The present invention addresses the problem of determining an area in which a user stays. A staying determination device 1 is provided with: a storage unit 10 that stores user state information which is time-sequential information about a moving state of each user and a proximity state of each user to other users; a grouping unit 13 groups, on a time sequence, users who are estimated to be staying in the same area on the basis of the user state information stored in the storage unit 10; and a determination unit 14 that determines, when one user in a group formed by the grouping unit 13 is identified to have stayed in one area within the time sequence of the group, that the other users included in the group have stayed in the one area within said time sequence. The moving state may indicate whether the user is moving. The proximity state may indicate other users to whom the user is close.
