Development of Kinesthetic Illusion Presentation System Considering the Muscle and Tendon Parameters

Abstract

The kinesthetic illusion phenomenon is attracting attention as one of the future rehabilitation techniques. The kinesthetic illusion is the illusion in which the proprioceptive sensation associated to the tendon and muscle occurs in the extension direction, when a vibration stimulus is given to the tendon. Our final goal is to control this kinesthetic sensation of this illusion with vibration stimulation. In this study, we construct a mathematical model of the kinesthetic illusion to realize this goal. We also conducted a psychophysical experiment to verify our proposed mathematical model of kinesthetic illusion. As a result of the experiment, it is clarified that the proposed model can express the relationship between the vibration stimulus and the amount of illusion. In the future work, we will develop the system which can control kinesthetic illusion which considers the proposed kinesthetic illusion model as well as the variation of the property of muscle.
