In this paper we present a fall detection system for elderly people. The core of the system is an intelligent sensor consisting of three accelerometers and a processor capable of analysing incoming data in real time and classifying motions events such as falls or other normal and abnormal events. The sensor is able to communicate these findings to nearby camera phones or PCs through Bluetooth for further processing. We have used the system to collect data of falls and nonfalls which we have used to evaluate different algorithms.
