1A1-I04 Relations of a Way of Falling and the Anatomical Severity(NEDO Project for Practical Applications of Service Robots)

Abstract

Because of parts of human body moving relative to one another, it is suggested by the fall experiment using the dummy doll that the anatomical severity varies according to a way of falling. The time series data of the acceleration of each physical part was analyzed by the principal component analysis. For the fall condition that HIC (Head Injury Criteria) level without the equipment used to protect the head became maximum, the time series data of the first principal component score in each fall condition was collated by the dynamic time warping method. As a result, it was suggested that if it was the same way of falling, it was of significance to examine the safety by the protective equipment and HIC.
