Abstract: Aiming at the complex ergonomics problem during the design of ship a new method was proposed. In this method,  the virtual human realtime kinematics model was built based on dynamic constraints and rotation information, it can drive standard human with different percent in virtual reality environment. Then the realtime motion data captured by tracking system was mapped to the kinematics model for driving virtual human. Based on abovementioned method the virtual human realtime driven module was designed and realized. It was integrated to ship product navigation system (SPNavis), which is a virtual design platform for ship design evaluation.  The module was verified by a case of evaluating valve and channel layout in ship engine room. The result shows that body action is simulated fidelity and the evaluation process is simple and useful.

Key words:  ship ergonomics, virtual human, virtual reality, real time driven, motion capture
