脑—机接口(BCI)是在人脑和计算机或其他电子设备之间建立的一种直接的信息交流和控制通道,是一种不依赖于常规大脑信息输出通路(外周神经和肌肉组织)的全新信息交流系统。介绍了BCI的组成及工作原理,讨论了基于脑电波(EEG)的BCI研究方法,指出了BCI存在的问题及研究对策。
The Brain-Computer Interface (BCI) is a direct communication and control channel established between the human brain and a computer or other electronic device. It is a protocol that is independent of the conventional brain information output pathways (peripheral nerves and muscle tissue) New information exchange system. The composition and working principle of BCI are introduced. The BCI research method based on brain wave (EEG) is discussed. The existing problems and countermeasures of BCI are pointed out.
