Abstract
While there have been many works on BMI and medical diagnosis by using brain signal, it is really hard to extract pure brain signals in noisy environment. Focusing on auditory related brain signal, we challenges to detect auditory evoked potential in real time by utilizing the newly developed EEG measurement system. The key idea is to utilize a master signal whose frequency is determined based on preliminary calibration tests. We evaluated the existence of auditory evoked potential by taking the correlation coefficient between the master signal and the auditory evoked potential of measured signal, and confirmed the effectiveness of the approach.
