摘要

在大多数P300 BCI实现中，使用RCP。然而，RCP易受邻接分散错误的影响。本研究提出了一种新的基于p300的脑机接口刺激表征-子块范式(SBP)。这种备选范式通过使用邻接分散效应大大提高了P300拼写性能。在本研究中，将收缩压性能与标准RCP进行比较。因此，SBP在P300拼写性能上比RCP更正确，也更方便用户。

P300 speller using a new stimulus presentation paradigm

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.
