多点同時振動刺激による肩関節の運動錯覚

抄録

Whether it is possible to induce stronger and steady kinesthetic illusions by multi-point vibratory stimulation was investigated. We placed seven vibrators on the arm and presented a total of 127 (2⁷ - 1) vibration patterns by turning each vibrator on and off, and asked participants to evaluate the illusion subjectively. The mean angular velocity and the mean subjective evaluation value increased significantly with the number of actuated vibrators. However, the illusion’s angular velocity did not increase dramatically. In short, the proposed method was effective for inducing vivid illusions steadily.
