Abstract
In this study we consider the mapping relation between machine movement and operation, and examine how maneuverability is affected by the mapping relation. We treat an example of that a one-degree-of-freedom slewing arm is operated with a mouse pointer. We evaluate the time of task achievement and reference error to realize operating unit which we can operate quickly and exactly. Then, we consider the influence of maneuverability when the mapping relation between the motion of slewing arm and the orbit drawn by mouse pointer is changed.
