Abstract:
1. A method for estimating a body pose in a body pose detection module provided with a triaxial accelerometer within a wireless sensor network of a plurality of body pose detection modules arranged to detect and simultaneously monitor body poses of multiple users, the method comprising steps of: performing signal pre-processing of a triaxial acceleration signal readout from the triaxial accelerometer at the body pose detection module attached to a user body so as to abstract a dynamic acceleration and a static acceleration of the triaxial acceleration signal; determining whether the dynamic acceleration of the triaxial acceleration signal is abnormal indicating that a body pose is a falling pose; and when the dynamic acceleration of the triaxial acceleration signal is not abnormal, analyzing the dynamic acceleration of the triaxial acceleration signal to determine whether a body pose is one of a static pose and a dynamic pose, wherein the signal preprocessing is performed by:
