Abstract
An information processing method, performed by a computer, includes: acquiring a beacon signal from a radio circuit coupled to a processor of the computer and configured to receive the beacon signal from a transmission source; calculating a length of a monitoring period, based on time intervals at which the beacon signal is received in a period of duration of a stationary state of the computer; and determining as being out of an area in proximity to the transmission source of the beacon signal in a case where the beacon signal is not received during the monitoring period having the length.
