Three-Dimensional Profiles of Movements of Human Body Joint Centers

Abstract

Certain results of an experimental ingestigation on motion profiles, in three-dimensional space for various body landmarks while the hand moves from one location to another are presented here. Grip, wrist, elbow and shoulder joint centers were of primary consideration for this study. A photogrammetric technique was adopted to record the movement and to extract the required information later. Seven subjects participated and 30 movements were performed by each of them under three different seat configurations and six controller locations. This research was initiated for the purpose of developing computer models in aircraft cockpits.
