In recent years, motion control has become one of hot topics in virtual assembly and it is an indispensable part in maintenance process simulation. However, motion control still remains at low level based on keyframe or inverse kinematics, which in turn leads to an over complicated modeling. The paper proposes a new method to control the virtual human directly. The method converts the instruction into natural-looking motion sequence so as to simulate maintenance process intuitively. There are two layers in our method: script-parsing layer and primitive layer. In the scriptparsing layer, the instructions are expressed with script in python. Our method converts the instructions into several kinds of primitives. The primitive layer converts the primitives with specified parameters into motion sequences. Our method generates natural-looking motions interactively and controls the virtual human intuitively. We view our method as a tool for facilitating the production of animation.
