Abstract :
In most implementation of a P300 BCI, RCP was used. However, RCP is susceptible to adjacency-distraction errors. This study presents a novel P300-based BCI stimulus presentation-the sub-block paradigm (SBP). This alternative paradigm substantially improved P300 speller performance by using adjacency-distraction effect. In this study, the SBP performance was compared to that of the standard RCP. Consequently, the SBP was more correct in P300 speller performance as well as more convenient for users than the RCP.
