Estimating the term…
A course of a mobile terminal device is estimated. An information processing system (S) includes: a plurality of transmission devices (1a, 1b) capable of transmitting predetermined radio waves; a terminal device (2) capable of receiving the predetermined radio waves; and a management device (3) communicably connected to the terminal device, wherein the terminal device (2) measures an intensity of the radio waves received from each of the plurality of transmission devices (1a, 1b) at intervals of a predetermined time period, and transmits measurement results to the management device (3), and the management device (3) estimates, from the measurement results, a distance from each of the plurality of transmission devices (1a, 1b) to the terminal device (2), and estimates a course of the terminal device (2) from the estimated distances.
An information processing system comprising:
A method performed in an information processing system including a plurality of transmission devices capable of transmitting predetermined radio waves, a terminal device capable of receiving the predetermined radio waves, and a management device communicably connected to the terminal device, the method comprising:
A management device to be communicably connected to a terminal device, wherein the management device receives, from the terminal device, measurement results of a radio wave intensity obtained at intervals of a predetermined time period, and estimates a distance from each of a plurality of transmission devices to the terminal device from the measurement results, and estimates a course of the terminal device from the estimated distances.
