Abstract—After the launch of the Bluetooth low-energy beacon, various studies and services using the beacon have been proposed. In particular, trilateration using three or more beacons is an indoor positioning technology based on the received signal strength indicator of beacons that has high accuracy. However, this method is difficult for ordinary people to use because it requires expertise in beacon installation and positioning analysis. Thus, this study proposes an application that allows for easy installation of beacons and records user movement information in the user’s home. The proposed application has the advantage of not having to accurately designate and install the beacon. The application can provide familiarity when checking user movement contents because the user can directly name the location once the beacon is installed. To verify the performance of the proposed application, we conducted an indoor movement recording experiment using beacons and the proposed application, and the experimental results showed high accuracy. Therefore, the proposed method will be a useful technology that can easily measure and record users’ indoor movement information in real life.
