ポインティングデバイスにおける操作端把持力の情報的利用Grasping must be considered with its purpose. As J. R. Napier indicated, when the purposes differ, grasping styles are different from each other, although the grasped object is the same. This suggests a possibility of detecting operator's will form grasping. In remote pointing devices, there is relationship between the motion of operation terminal and that of the pointer. In usual, the gain of this relationship is not adaptive in operation even though it is adjustable before the operation. But this gain adjustment is a quite difficult function. According to Fitts' law, pointing tasks is easier when the target is larger and the distance is shorter. Large gain means the short distance and small target, small gain means, as opposite to above, long distance and large target. This paper proposes a realtime adaptive gain adjustment for an answer of this dilemma. And it is recommended that this adjustment be controlled by operator's grasping force of operation terminal to avoid increase of complexity of operation. For an example, a computer mouse with realtime adaptive Mickey ratio adjuster is considered.
