It is known that a phenomenon called kinesthetic illusion occurs when vibration stimulation of tendons causes the illusion of body movement without any actual body movement. However, there are substential inter-individual variability exist in the likelihood of occurrence and strength of this illusion, and methods to increase the occurrence probability or strengthen the magnitude of the illusion have not yet been developed. In this study, we hypothesize that the cause of the difficulty in consistently inducing the illusion is the difference in the mechanical properties of the tendon and the contactors that present the vibration stimulation. Therefore, we investigate whether it is possible to increase the occurrence probability of the kinesthetic illusion by developing contactors with mechanical properties that match the viscoelasticity of each tendon.
