Three-dimensional Lifting-up Motion Analysis for Wearable Power-assist Device for Lower-back Support

Abstract

The objective of this paper is to understand human motion, particularly lifting–up motion for controlling a wearable power assist device. Conventional studies on the motion analysis only consider two–dimensional motions assuming symmetrical motion. However, actual human motions are three–dimensional. This paper presents the analysis of three–dimensional position data of human lifting–up motions are acquired by an optical motion capturing system.
