Japanese Patent JP7244749
Kind Code:
B2
Abstract:
An object is to estimate the course of a movable terminal device. 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. The terminal device (2) measures intensities of radio waves received from the transmission devices (1a, 1b) at predetermined times, and transmits measurement results to the management device (3). The management device (3) calculates distances between the terminal device (2) and each of the transmission devices (1a, 1b) at the predetermined times from the measurement results, and calculates positions of the terminal device (2) at the predetermined times from the calculated distances.
