The P300 speller, one of the most renowned BCIs for communication, allows users to select letters just by thoughts. However, due to the low signal-to-noise ratio of the P300, signal averaging is often performed, which improves the spelling accuracy but degrades the spelling speed. The authors have proposed reliability-based automatic repeat request (RB-ARQ) to ease this problem. RB-ARQ could be enhanced when it is combined with the error correction based on the error-related potentials (ErrPs) that occur on erroneous feedbacks. Thus, this study aims to reveal the characteristics of the ErrPs in the P300 speller paradigm, and to combine RB-ARQ with the ErrP-based error correction to further improve the performance. The results show that the ErrPs observed in the current study resemble the previously reported ErrPs observed in a cursor control task using a BCI, and that the performance of the P300 speller could be improved by 35 percent on average.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.132 No.5 （2012） 特集：新たな産業応用を可能にする無線通信技術本誌掲載ページ: 713-720 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/132/5/132_5_713/_article/-char/ja/
