In this paper, we developed the indoor positioning system with infrared (IR) beacon, and we evaluated the utility of the proposed system through a dynamic measurement experiment and a static measurement experiment with multiple IR beacons. In these experiments, we verified positioning capability of the IR system and the Bluetooth Low Energy (BLE) system in the metal shelves environment imitating retail stores. As a result, it is confirmed estimated position of the IR system is more accurate than the BLE system in dynamic measurement. The average positioning error was 147 mm with multiple IR beacons, and estimated movement of pedestrian corresponds actual movement.
