Abstract
The research field of movement analysis is very broad and it includes areas such as motion editing, motion prediction, and motion vocabulary control. This research uses the MTM system to define motion elements. Then, we use C Language to design the MTM motion command in order to let users to conduct motion analysis conveniently and further design the operation executing plat form. This research established a set of correct, prompt and automated motion analysis system. The 3D digital information comes from the captured motion of assembly operation. Users only need to enter simple instruction to analyze the motion information which is collected by computers. Therefore, they can get the description of motion sequence, estimate the working time. Finally, we use the analysis result to simplify the motion operation as well as standardize the method of operation.
