This study used the traditional P300 speller paradigm to compare a medical grade EEG system, the G.Tec, with a consumer grade EEG system, the Emotiv, in the detection of P300 components within ERP signals. The experiment focused on four electrodes known to produce optically induced visual evoked potential. A successful comparison of the two approaches was made. It was shown that both systems could measure an ERP. The paper concludes with discussion comparing the low-cost wireless EEG system with the medical grade EEG system.
