Poster Abstract: Using Low-Cost, Non-Sensor-Equipped BLE Beacons to Track People's Movements

This study presents a room-level people tracking system capable of determining people's movements while carrying a non-sensor-equipped BLE (Bluetooth Low Energy) beacon. The BLE beacon broadcasts BLE advertisement while people are in motion. A beacon receiver (BR) was installed in a room near the doorframe to determine people's movements (i.e., entering, departing, or passing by the room), based on the variations in received signal strength (RSS) over time. This system is aimed at providing tracking information for people in school buildings, hospitals, and nursing homes. Knowing in which room or area people are has many useful applications, and the system is low-cost and easy to install and maintain.
