Research on hand grasping strategy for ergonomics simulation

Study on grasping strategy of dexterous hand can contribute to realization of realistically interactive simulation between human and machines. This paper introduced a new method which combined grasping plan with posture prediction to realize grasping strategy for ergonomics simulation. Based on classifying hand gestures, a new method of modeling virtual prototype was presented, which embedded interactive operation features into the prototype model. This paper also presented a method of GA-based grasping posture prediction which maximized human posture comfort level. Simulation results on Jack platform indicates this method can effectively predict hand grasping gesture and improve the verisimilitude of simulation.
