A Survey On Efficient Human Fall Detection System

ABSTRACT Falling is among the most dangerous events that often happen among senior people patients and may need immediate medical care. Automatic fall detection systems could help old people and patients to live independently. A real-time fall detection system may help us to detect fall events among elderly people in time and reduce the overall casualty rate. The proposed system uses the accelerometer and tilt sensors to design a real-time fall detection system that not only can distinguish up to 4 different kinds of fall events forward backward rightward and leftward but is also portablewearable low-cost and with high accuracy rate. Because the waist is the centre of gravity in the human body the system is used more effectively when placed at the waist. The system includes an automatic real-time fall detection device and GSM instant messaging function which can transfer fall alert send emergency help messages.
