Abstract

Event-related potentials elicited by two individual oddball tone sequences presented to both right and left ears can be used to realize auditory BCI to detect selected attention. In this study, event-related potentials elicited by oddball tone sequences were examined and the methods to pre-process the data (spatial filter, frequency filter and down sampling) were investigated to improve pattern classification accuracies. As a result, it was shown that the down sampling (100 Hz) of the measured data was prominent for improving the classification accuracies (over 85%) in all of six subjects.
