通用USB脑电采集及压力状态分析系统开发

The Development of General USB EEG Acquisition and Pressure Analysis System

介绍了一种基于USB的通用脑电采集及压力状态分析系统。该系统借助当前流行的JavaFX技术实现了对一般脑电设备的数据采集和多形态可视化。可视化工作用视觉表现脑电数据,即将数据中隐含的某种有规律的特征信息转化为一个表特征模型,可以让用户不经过分析庞大的原始数据,就可以得到一个所需结果的直观图形。基于系统采集的脑电数据,对用户的压力状态进行了初步分类和分析,并在可视化系统帮助下利用生物反馈技术实现了用户的主动压力缓解。

This paper gives a method to develop an EEG acquisition and pressure analysis system based on general USB in- terface. The system realized data acquisition and visualization of brain electrical signal by the current popular JavaFX technology. Visualization makes the EEG data to be performed in visual , which means that transform the regular feature in- formation which is bidden in the data to a visible feature model. Further, based on the EEG data acquisition system,the pressure state of the users could be classified and analyzed. Users could release their pressure actively by using biofeedback technique with the system＇s help.
