Inclination gradient-based fall detection algorithm for wrist-worn device

Abstract

Fall detection is one of the feasible solutions for solving the problem of aging of population. This paper presents an algorithm to detect falling for the elderly with one wrist-worn device. The algorithm has lower computation complexity to determine the fall event according to the inclination gradient. Experimental results show that it performs better than another similar devices with the average sensitivity and specificity of 94.44% and 100%, respectively.
