A Motion Characteristics of "Get and Place" Activity

This paper presents a proposal to improve productivity and provide a more reasonable work area. The method of research is to observe and measure the motion characteristics of a typical sitting worker doing "get and place." The valuation index used in the experiment is obtained by measuring the length of the arms, the motion locus, the motion velocity, the motion time, and the amount of myoelectric discharge. The results lead to an experimental formula expressing the relation between the motion time and the length of the arms. This paper also showed that a work area, which takes into consideration the difference of a physique of the worker, could minimize the scattering of motion time by the worker resulting in a more efficient and reasonable work place.
