非対称振動刺激による牽引力錯覚の研究動向

抄録

When presented with asymmetric vibrations, humans typically experience an illusory force that is similar to the sensation of being pulled toward a particular direction. The pulling illusion has been used in new display elements for a pedestrian navigation system and a VR content because the asymmetric vibrations can be implemented in a small non-grounded device. This paper reviews the findings of the pulling illusion with covering a wide range of topics, including the basic concept, physiological mechanism, optimal parameters for the illusion, the control method of force vectors, the evaluation method of the illusion, and applications. As a result of the review, the research trend of the pulling illusion was confirmed, and the vital points which were stimulation method and parameters of asymmetric vibration to design a haptic interface using the illusion were clarified.
