This article describes a fall detection method based on Bi-axial Sensor SCA100T.We collect angle data recorded by a wearable inclinometer placed at users' waists.The angular data are transmitted to PC by wireless data transmission device.Then,the fall duration is divided into three phases and we make threshold-based fall-detection decisions in every phase after feature extraction and analysis of the short-time angle data.Finally,a robust fall detection result is given by comprehensive considerations of the three phases decisions.The experiment results prove that the fall detection is effective and the accuracy is up to 97.23% without undetected falls.
