Digital Human Model Simulation을 위한 RAMSIS 추정 운전자세의 정합성 평가 및 개선 = Evaluation of Predicted Driving Postures in RAMSIS Digital Human Model Simulation

다국어 초록 (Multilingual Abstract)

For proper ergonomic evaluation using a digital human model simulation (DHMS) system such as RAMSIS<SUP>®</SUP>, the postures of humanoids for designated tasks need to be predicted accurately. The present study (1) evaluated the accuracy of driving postures of humanoids predicted by RAMSIS, (2) proposed a method to improve its accuracy, and (3) examined the effectiveness of the proposed method. The driving postures of 12 participants in a seating buck were measured by a motion capture system and compared with their corresponding postures predicted by RAMSIS. Significant discrepancies (8.7° to 74.9°) between predicted and measured postures were observed for different body parts and driving tasks. Two methods (constraints addition and user-defined posture) were proposed and their effects on posture estimation accuracy were examined. Of the two proposed methods, the user-defined posture method was found preferred, reducing posture estimation errors by 11.5% to 84.9%. Both the posture prediction accuracy assessment protocol and user-defined posture method would be of use for practitioners to improve the accuracy of predicted postures of humanoids in virtual environments.
