Abstract
A fall detection method determines a fall detection algorithm based on sensor data aggregated from a plurality of fall detection devices. Sensor data is obtained from one of the plurality of fall detection devices not included in the aggregated sensor data. A probable fall event of the obtained sensor data is determined based on the fall detection algorithm. An alarm signal is generated based upon the determination of the probable fall event. A validity of the probable fall event is determined, and the fall detection algorithm is refined using the obtained sensor data and the validity of the probable fall event each time sensor data is obtained from any of the plurality of fall detection devices.
