Abstract: This paper presents the results of a comparison of manikin posturing within and between simulation engineers. Five simulation engineers were asked to simulate four manual assembly cases. They repeated each task six times, three times with a posture prediction tool and three times with manual adjustment of the body angles. The results show that the posture-prediction-tool was not used in an optimal manner. Although the prediction-tool was quick at suggesting a likely posture, the simulation engineers were reluctant to consider a simulation task completed until the manikin's posture was realistic in all aspects. The comparison indicates that if a posture-prediction-tool is to be beneficial, results with postures containing some non-cosmetic elements must be accepted. It is not until such an acceptance is achieved that the successful use of a posture-prediction-tool will become a reality.
