Operational assistance system for crane using interactive adaptation interface-design of 3D virtual crane simulator for operation training

A rough terrain crane has excellent operativity and mobility, yet the operation of the rough terrain crane is very difficult because of complexity of the control system, payload´s swing, lack of information, etc. These problems can be settled by intelligent crane system if it can assist an operator to perform efficient crane operation. We proposed an assistance system for crane operation using an interactive adaptation interface. The assistance system produces various kinds of operational assistance. In this paper, we propose a crane simulator system for operation training using the proposed crane system. The proposed system has a function called multimodal display which presents various kinds of operational assistance. We consider the realization of the training system by adaptation of the strength of operational assistance based on operator´s state; we focus on the operators skill level. We propose an adaptation method based on operational skill and perform simple operation experiments to confirm the effectiveness of the method described
