摘要
首先介绍了脑机接口(brain-computer interface,BCI)系统的概念和基本组成,交互技术在系统中的重要作用,以及目前国际上比较典型的交互技术;其次鉴于当前交互技术中存在的不足,分析了如何使人在脑机接口系统发挥更重要的作用,提出了一种新的脑机接口实验范式,该范式中随着被试操作技能的提高系统性能可以得到明显提升;之后建立了该实验范式的原型机系统——基于BCI的倒摆交互控制系统;最后对脑机交互技术的发展及脑机接口技术未来的应用做了展望。
This paper first reviews the concepts and the basic components of the brain--computer interface （BCI） system as well as the importance of interaction technology in it and several typical worldwide successful BCI systems, followed by the analyses of disadvantages of the current interaction means together with the way of how to conquer these drawbacks. The key point was located on the new experiment paradigm and the model of the pendulum interaction control system based on it. Advancements of interaction technology and applications of BCI have also been referred to at the end of the paper.
