This study reports the estimation of different-threshold (DT) when humans recognize various modulated vibrations using their tactile sensor. The modulated vibration consists of two frequency components. A psychological or the event related potential (ERP) measurement was used to estimate DT. ERP appears in an electro-encephalogram (EEG) when a human recognizes the information emitted by an external stimulus, and this study detects P300, which is a component of ERP.This paper proposes a single-trial analysis that uses the T-test, which deviates from the conventional method for detecting P300 called the averaged EEG method. Finally, the proposed method estimates DT. As a result, the effectiveness of the proposed method is assured by estimating DTs on five subjects.
