Abstract
In this study, we investigate the vibratory perceptual characteristics that relates to the position of the finger and the hand. We focus on an elastic characteristic of the skin and measured the resonant frequency at the multiple positions of the hand. Next, we measured the perceptual thresholds of each position for vibratory stimulus in order to examine the relationship between the resonant frequency and the sensitivity curve of haptic perception. As a result, we verified that the vibration characteristic of skin elasticity affected the sensitivity of Meissner's corpuscle, while it did not affect the sensitivity of Pacinian corpuscle. Based on our experimental results, we propose a new sensitivity mechanism which coincides with perceptual characteristics.
