Abstract (in Japanese) (See Japanese page) 
(in English) With the rapid spread of smartphones, it is focused on the service that prompts a change of the purchasing behavior of the user called O2O (Online to Offline). Also, as a technique for realizing such O2O, indoor positioning using BLE (Bluetooth Low Energy) tags is recognized as a promising technology. BLE tags periodically broadcast the radio signal with IDs. By receiving and analyzing the received signal strength (RSSI, Received Signal Strength Indication) of BLE tags installed at the environment, a smartphone can estimate its position. However, when the positioning is simply done in proportion to the RSSI value, the error occurs due to the effect of reflection from the walls. Therefore, this paper evaluates a fingerprinting method which makes positioning by comparing with the training data. Furthermore, it evaluates the effect of positioning accuracy by changing the number of BLE tags installed in the environment.
