In this paper, we considered auditory stimulations for Brain-Computer Interface (BCI) based on the cognitive P300 event-related potentials (ERP) in order to assist with the communication in severe physical limitation persons. At first, our results showed that it was possible to deduce P300 ERP in air-conducted and bone-conducted auditory oddball paradigm using three pairs of stimuli consists of tonepip pair and toneburst pairs with/without onset and offset. Next, we have introduced a baseline method for evaluating a P300 amplitude. As a result, we found that P300 was dominant at electrode site Pz for each auditory stimulus. In addition, P300 amplitude of the toneburst stimuli was higher than that of the tonepip stimuli.Furthermore, the optimal conditions of auditory stimuli such as sound pressure level, frequency and duration were considered for deriving the P300 wave. With these experiments, a certain range in the above parameters of auditory stimuli could be determined. |
