    Accidental fall can cause physical injury, fracture and other health complications, especially for elderly people living alone. Aimed to provide timely assistance after the occurrence of falling down, a pre-fall alarm system was proposed. In order to test the reliability of the pre-fall alarm system, eighteen subjects who wore this device on the waist were required to participate in a series of experiments. The acceleration and angular velocity time series extracted from human motion processes were used to describe human motion features. HMM-based SVM classifier was used to determine the maximum separation boundary between falls and Activities of Daily Living (ADLs). The fall detection results showed 94.91% accuracy, 97.22% Sensitivity and 93.75% Specificity. The proposed device can accurately recognize fall events, achieve additional functions, and have the advantages of small size and low power consumption. Based on the findings, this pre-impact fall alarm system with a detection algorithm could potentially be useful for monitoring the state of physical function in elderly population.
