錯覚を利用した牽引力感覚提示装置の小型軽量化とその効果

抄録

When a small object in a hand-held device moves periodically and prismatically with asymmetric acceleration (strong in one direction and weak in the other), one typically experiences the kinesthetic illusion of being pushed or pulled continuously by the held device. This effect was investigated because of its potential application to a hand-held, non-grounded, haptic device that can convey a sense of a continuous translational force in one direction, which is a yet missing the in haptic research. Here, a one-degree of freedom haptic device based on a double-layer crank-slider mechanism was constructed based on the results of our previous research. We evaluated the effectiveness of the perception of directed force sensation by asymmetric oscillation compared with prior prototype, and the effectiveness of the gross weight of the device. Our results show that the ratio of the gross weight of the device and the weight of reciprocating mass should be at least 16%for effective force perception.
