Ship Ergonomics Evaluation Based on Virtual Human Real-Time Driven Modeling Technology

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.
