Description

EEG-based spelling devices have a possibility to provide a communication tool to patients who severely paralyzed. We have made a spelling device based on the P300 event-related potential and investigated a proper channel to control the spelling device to lower costs. We used seven parameters (channel of EEG signal recording, font size of characters, index of estimation, preprocessing method of EEG signals, data length, method of character estimation and the number of times of EEG signals recording to calculate the arithmetic mean of EEG signals) to evaluate the performance of the spelling device. As a result, the accuracy rate increased with channel C4 or P4. However, there were individual differences in the proper channel to control the device.
