パワーアシスト装置操作時の人間の重量知覚特性

抄録

Power assist devices are very useful for reducing the burden of, especially, elderly and women operators who involve in hard work tasks. In the operation of the power assist device for carrying an object, the operator not only has a feeling of wrongness but also does dangerous operation if there is a big deference between an expected and sensed feeling of the weight. The feeling deference can be reduced if the sensed feeling of the weight can be controlled without changing the burden to the operator. In this report, a method for controlling the sensed feeling of the operator and the effectiveness is shown experimentally.
