Abstract
A vibration sensitivity is usually defined by the minimum amplitude when a subject perceives the vibration with ω1 which is the frequency of perpendicular direction on the skin surface. In this work, we are interested in how the vibration sensitivity at ω1 is changed under the condition adding the tangential vibration with ω2 which is the frequency of tangential direction on the skin surface. Through all experiments, we found that the vibration sensitivity at ω1 = 8, 10, and 25 Hz is improved approximately 30% with the p-value of below 0.1% by an adequate setting condition of ω2 = 3 Hz.
