However, there has been no study that tried to the evalution of cognition to the modulated vibration in the tactile sensor of human. In this paper, we propose the method that the cognition level of the discrimination to the modulated vibration stimulus is evaluted based on the Event Related Potential (From now on, it is written with ERP). Modulated vibrations (fH, fL) Hz generated from the high band component fH (from 40, 200Hz) and the low band component fL (from 2,20Hz). Then, We expressed a certain modulated vibration as 1 point in the frequency area fHvs. fL. We measured the distribution of the discrimination threshold at the frequency area fHvsL fL based on the proposed evalution method by the ERP. As a result of the experiment, it is reported because the effectiveness of the proposal method was confirmed.
