Title: POSITION DETECTION SYSTEM
Abstract:
A position detection system (1) is provided with a sonic device (10) and an information terminal (20). The sonic device is placed in a predetermined designated region, and is provided with a device controller (15) and a device transmitter (11). The device controller acquires positional information that is information including the position of the sonic device. The device transmitter (11) transmits, as detection sonic waves, sonic waves on which the positional information is superimposed. The information terminal is provided with a terminal receiver (21) and a terminal controller (24). The terminal receiver receives the detection sonic waves. The terminal controller acquires the positional information superimposed on the received detection sonic waves, and stores the acquired positional information in a storage device as information indicating the position of the designated region.
