Assistance system for crane operation using multimodal display

We apply the interactive adaptation interface to an operation system. Such a system can adapt to an operator considering the following two points. One is the operator´s psychological state and the other is the operator´s skill. For adaptation to an operator, the system tunes the time constant of the operation controller by recursive fuzzy inference, and has a “multimodal display” which consists of various types of operational assistance such as visual display, acoustic display, force display, etc. In this paper, we propose many types of operational assistance for a rough terrain crane system. We propose a good control pattern which can suppress the payload´s oscillation. The operational assistance becomes more effective by using the control pattern. We made a computer simulation and a joystick for the proposed crane system, and did operational experiments on this simulator. We show the effectiveness of the proposed assistance system for crane operation
