视觉诱发电位脑机接口关键技术研究

脑机接口（brain—computerinterface，BCI）是近10年发展起来的一种新颖的人机接口方式．它是不依赖于脑的正常输出通路（外周神经系统及肌肉组织）的脑机（计算机或其它装置）通讯系统．脑机接口的一个重要用途不仅为那些思维正常但有严重运动障碍的患者提供语言交流和环境控制途径，还在工业、航空、军事等领域也有潜在的应用价值．本文介绍了基于视觉诱发电位脑机接口的工作原理，从系统设计、数据获取及处理方法等方面论述了脑机接口设计中的关键技术，最后指出了视觉诱发电位脑机接口存在的主要问题和发展趋势．

Researches of key techniques on brain-computer interface of visual evoked potential

Brain-computer interface(BCI) is a new kind of human computer interface being explored since last decade,and BCI is one kind of communication system which does not depend on the brain's normal output channels of peripheral nerves and muscles.One of the most important functions is that this technology could be a new valuable augmentative communication option for those with severe motor disabilities that prevent them from using conventional augmentative technologies.BCI technology also has potential applicati...
