摘要

针对传统脑电型非侵入式脑-机接口判断正确率低、信息传输率低等问题，设计了一种基于SSVEP阻断和P300双特征的混合范式P300-SSVEP-Speller脑-机接口系统.对12位受试者进行了脑电诱发及目标识别实验，结果表明：本范式能够同时诱发出SSVEP阻断特征信号和P300特征信号，采用联合特征的新型的P300-SSVEP-Speller系统比传统的P300-Speller系统具有更高的判断正确率和信息传输率.

Abstract

To solve the problems that the conventional brain-computer interfaces (BCIs) transfer the mental intents into the control commands with a low judgment accuracy and unsatisfied information transfer rate (ITR)

a novel hybrid BCI called the P300-SSVEP-Speller was developed on the basis of the P300-Speller to combine SSVEP blocking (SSVEPB) features with P300 potentials.The offline usage of twelve subjects was investigated in the study.Results show that the elicited SSVEPB has little influence on the emergence of the P300 potentials in the degree of temporal signals.In addition

from the view of character recognition

the novel P300-SSVEP-Speller system has a better performance than the conventional P300-Speller on the judgment accuracy and ITR.
