P300拼写器是一种脑机接口（BCI），通过检测脑电图（EEG）中的P300事件相关电位，使受试者能够在计算机屏幕上拼写文本。这种脑机接口的应用是特别感兴趣的残疾患者失去了所有的语言和运动的沟通方式。脑电中的错误相关电位（ErrPs）是由被试对错误的感知产生的。我们报告了使用这些errp来提高P300拼写器性能的可能性。我们总共对9名受试者进行了测试，研究了他们对BCI正确和错误表现的脑电图反应，将我们的研究结果与之前的研究结果进行了比较，探讨了检测ErrP的可能性，并讨论了将ErrP分类器集成到P300拼写系统中。(C) 2011 Elsevier B.V.版权所有
A P300 Speller is a brain-computer interface (BCI) that enables subjects to spell text on a computer screen by detecting P300 Event-Related Potentials in their electroencephalograms (EEG). This BCI application is of particular interest to disabled patients who have lost all means of verbal and motor communication. Error-related Potentials (ErrPs) in the EEG are generated by the subject's perception of an error. We report on the possibility of using these ErrPs for improving the performance of a P300 Speller. Overall nine subjects were tested, allowing us to study their EEG responses to correct and incorrect performances of the BCI, compare our findings to previous studies, explore the possibility of detecting ErrPs and discuss the integration of ErrP classifiers into the P300 Speller system.
