<P>PROBLEM TO BE SOLVED: To provide a behavior range grasping method and a behavior grasping apparatus which can always grasp user's behavior by estimating the topology of a user's moving route only by carrying a compact terminal without using positional information such as GPS coordinates. <P>SOLUTION: The behavior grasping apparatus 100 is provided with: a detection part 101 for receiving beacon signals periodically transmitted from access points of IEEE802.11 and specifying the access points existing in a periphery; a history storage part 102 for storing the specified access points as history data of each detection period; a route estimation part 103 for specifying deviation time that the combination of access points hardly coincide with that of past detection periods and recovery time indicating high coincidence, estimating a position in a grasped route at the deviation time and the recovery time and estimating the topology of a moving route; and a display part 104 for mapping the topology of the moving route and displaying the mapped topology as a user's behavior range. <P>COPYRIGHT: (C)2009,JPO&INPIT |
