科学领域:

神经科学和生物医学工程
人与计算机的交互
信号处理信号处理

背景情况:

用户的心理状态,特别是丧,显著影响主动大脑计算机接口 (aBCI) 的性能.
开发被动脑计算机接口 (pBCI) 来监控用户情绪对于自适应的BCI至关重要.
挫折是影响用户参与和BCI表现的关键心理状态.

研究的目的:

开发一种结合aBCI和pBCI的新模式,以测量和适应用户丧水平.
为了研究挫折对运动图像 (MI) 的影响,基于aBCI性能.
通过通过pBCI结合实时挫折检测来提高aBCI准确性.

主要方法:

设计了一个新的实验范式,使用视觉反来诱导不同的丧水平.
对pBCI (丧检测) 和aBCI (MI分类) 收集了脑电图 (EEG) 数据.
过器银行常用空间模式 (FBCSP) 和支持矢量机 (SVM) 用于特征提取和对挫败级别和MI任务的分类.

主要成果:

通过使用FBCSP+SVM,pBCI成功地分类了三个挫折级别 (低,中等,高).
与传统方法相比,两种结合pBCI结果的新方法提高了aBCI平均分类精度7.40%和8.62%.

关键词:
