Abstract
Nowadays, the application of digital human models becomes broader and more promising. By using the motion capture system or manipulating the digital human models manually, it can easily simulate human tasks in the virtual world. Thus, this study aims to develop a VR system to allow users simulating assembly tasks and conducting real-time evaluation.In this study, we used the HMD, 3D position devices, and 5DT data gloves to manipulate the digital human model. In addition, the 5DT data gloves can make users interact with virtual objects with their hands to simulate assembly tasks. Finally, with the support of 2D biomechanical models, we can conduct real-time biomechanics evaluations in design improvement.By integrating the DHM with interaction mechanism and 2D biomechanical models, we can simulate the vehicle door assembly tasks. In the virtual assembly, the process flow and layout can be visualized. In the evaluation of real task, hazardous postures can be determined and then be improved. Finally, with both virtual tasks and real-time evaluations, we can evaluate a new workstation in a production line. The system can reduce the time and cost for the design of a new workstation. Besides, the improvements can be realized in an efficient and cost-effective manner.
