人間一機械系における手先の微細調整について

There are few studies on man-machine system to clarify the delicate behavior of human hand which is observed in an assembling line and so on. The purpose of this study is to make clear such delicate behavior of human hand in the man-machine system. From this point of view, the compensatory tracking system is constructed and each significance of various factors which may affect on the experiment is inferred by the method of variance analysis. Especially, to clarify the delicate behavior of human hand, the control sticks which are operated by the small movement of fingers are used. Each control stick is supported by a spring, which has small compliance, on the work table, so that the fingers of human operator can accept the reaction force which is proportional to the displacement of the control stick. Through whole experiments on this study, the following facts are made clear comparing with other researches as (1) adaptability of human operator to the change of the system loop gain ; (2) control ability of human operator for the difference of control sticks ; (3) adaptability of human operator to the input bandwidth ; and (4) relation between the control ability of human operator and the input magnitude.
