<p>PURPOSE: To efficiently obtain the shift information of a testee by sending the position information indicating the positions from multiple positions in a subject area, receiving signals each time the testee passes through the positions, transmitting the identification information containing the position information and testee information, and receiving the identification information. CONSTITUTION: A worker fitted with a worker light receiver 3 moves in a hall 2, and light projector IDs (identification information) transmitted from light projectors 1 via infrared-rays are received by the light receiver 3 each time the worker passes under the hall light projectors 1 provided on the ceiling. The light receiver 3 transmits the identification information containing the light projector IDs and the light receiver ID each time it receives the light projector IDs to an information processor 5. The transmitting worker and the position can be specified by the information at each time. The information is accumulated and processed in time series, and the shift locus, total shift distance, and moving speed of each worker can be obtained.</p> |
