摘要: 脑-机接口是在人脑与计算机或其它电子设备之间建立的直接的交流和控制通道,通过这种通道,人就可以直接通过脑来表达想法或操纵设备,而不需要语言或动作,这可以有效增强身体严重残疾的患者与外界交流或控制外部环境的能力,以提高患者的生活质量.脑-机接口技术是一种涉及神经科学、信号检测、信号处理、模式识别等多学科的交叉技术.本文对脑-机接口技术的发展、研究现状、工作原理以及涉及的关键技术进行了较为详细地综述,在总结脑-机接口技术存在问题的基础上,探讨了该领域进一步研究的方向.

Abstract: Brain-computer interfaces provide a direct communication and control channel for sending messages and instructions from brain to external computers or other electronic devices.Using the non-muscular channel,subjects with severe neuromuscular dysfunction can directly express their thought and manipulate the external devices without using human language and actions.This will greatly enhance the ability of these subjects to manage external event and will improve their living quality.Brain-computer interface technology is an interdisciplinary technology integrating neurology,signal collection,signal processing,pattern recognition and more other relevant techniques.In the present paper,we review the development,the rationale and the methodology of BCI's technology and the major limitations in the BCI's implementation and applications,and then discuss some vital aspects that may be conducted in the future investigations.

Key words: brain-computer interface, electroencephalogram, event-related potentials, feature extraction, communication
