脑机接口(BCI)的目的是将反映外界刺激或心理任务所引起的大脑神经活动的大脑信号翻译成相应的命令，从而提供人脑和机器之间的直接通信。基于P300的脑-机接口已被证明是最可靠和最独立于主体的范式之一。然而，现有的基于P300的脑机接口只使用单一的通道，即视觉刺激诱发电位。为了进一步提高脑机接口系统的可靠性，本文提出了一种同时利用听觉和视觉刺激的混合式脑机接口。实验结果表明，混合刺激诱发的事件相关电位与单一视觉诱发的事件相关电位有明显不同，与传统的P300脑-机接口系统相比，混合脑-机接口系统具有更高的可靠性。
Brain Computer Interface (BCI) aims to translate the brain signals, reflecting the neural activities of brain evoked by external stimuli or mental tasks, into the corresponding commands, which thus provides a direct communication between human brain and machine. P300 based BCI has demonstrated to be one of the most reliable and subject independent paradigm. However, the existing P300 based BCI only uses single modality, i. e., visual stimuli evoked potential. In this paper, to further improve the reliability of BCI system, we develop a hybrid BCI by using auditory and visual stimulus simultaneously. Experimental results demonstrate that the event-related potentials evoked by hybrid stimulus are significantly different with single visual evoked potentials, and our hybrid BCI shows more reliable performance than the traditional P300 BCI system.
