摘要
脑机接口 (BCI)是一种基于脑电信号实现人脑与计算机或其他电子设备通讯和控制的系统 ,它不依赖人体的外周神经神经系统及肌肉组织 ,是一种新的人机接口方式 ,在康复医学和控制等领域有应用前景。近年来 ,脑机接口技术发展迅速。概述了采用事件相关电位P30 0、稳态视觉诱发电位(SSVEP)、事件相关同步或去同步 (ERS ERD)、皮层慢电位 (SCP)、自发EEG信号、植入电极等实现脑机接口技术的研究方法 ,讨论和比较了各种研究方法的特点和局限 ,介绍了脑机接口的发展现状和存在的问题 。
Brain computer interface(BCI) is an EEG based communication and control system between human and computer or other electric devices, which does not depend on the brain's normal output channels of peripheral nerves and muscles. It is a novel kind of human interface, may have applications in rehabilitation, control and other fields. The developming speed of brain computer research in recent years is high. Methods of how to use P300, SSVEP, ERS/ERD, SCP, spontaneous EEG and implanted electrode to realize BCI are introduced. Characteristic and limitation of different methods are discussed. Status, problems and application prospects of BCI technology are also included.
