Design and Application of Human-machine Interactive Experimental Platform Based on EEG

基于脑电信号(electroencephalogram,EEG)的人机接口研究是目前国内外研究热点之一,本文针对脑电信号在强噪声背景下微弱的特点,讨论了基于脑电信号的低功耗、移动式、开放接口的人机交互实验平台系统的设计方法和应用。综合利用先进的硬件和软件滤波技术、隔离技术、高速通用串行接口技术以及虚拟仪器技术来提高平台各方面的性能。将此平台用于脑电诱发信号提取得到了满意的结果,从而为基于脑电信号的开放性人机交互平台的实现提供了新的思路,为脑电信号的研究带来了方便。

The human-machine interface based on EEG （electroencephalogram） is one of the hotspot in the research field. Aiming at the weak characteristics of EEG in the background with strong noises, the design methods and applications of a low power consumption, portable and open interface human-machine interactive experimental platform based on EEG is presented in this paper. The advanced technologies of hardware and software filter, isolation, universal serial bus and virtual instruments are fully used to improve the overall performance of the platform, The platform shows good stability and reliability in acquiring the Steady State VEP （SSVEP） EEG. As a result, a new idea is provided for realizing the opening human-machine interactive experimental platform based on EEG, and it brings convenience for the EEG research.
