A cloud based Bluetooth Low Energy tracking system for dementia patients

Abstract

Location based services of trackers can keep dementia patients safe, but traditional GPS tracker or smartphone based solution device need to be removed for recharging or when taking bath. A water-proof Bluetooth Low Energy (BLE) tag with a CR2302 battery can be used over a year so that it can be worn all the time. By combining BLE technology, smartphones and cloud services provided by Google, we can build a practical location and tracking system with minimal cost.
