A framework of motion capture system based human behaviours simulation for ergonomic analysis

摘要

With the increasing of computer capabilities, Computer aided ergonomics (CAE)offers new possibilities to integrate conventional ergonomic knowledge and todevelop new methods into the work design process. As mentioned in [1],different approaches have been developed to enhance the efficiency of theergonomic evaluation. Ergonomic expert systems, ergonomic oriented informationsystems, numerical models of human, etc. have been implemented in numericalergonomic software. Until now, there are ergonomic software tools available,such as Jack, Ergoman, Delmia Human, 3DSSPP, and Santos, etc. [2-4]. The mainfunctions of these tools are posture analysis and posture prediction. In thevisualization part, Jack and 3DSSPP produce results to visualize virtual humantasks in 3-dimensional, but without realistic physical properties. Nowadays,with the development of computer technology, the simulation of physical worldis paid more attention. Physical engines [5] are used more and more in computergame (CG) field. The advantage of physical engine is the nature physical worldenvironment simulation. The purpose of our research is to use the CG technologyto create a virtual environment with physical properties for ergonomic analysisof virtual human.
