摘    要:为提取应用于脑-机接口系统的稳态视觉诱发电位信号(SSVEP),运用叠加平均与快速傅里叶变换(FFT)相结合的方法,由其频谱图上得到作为输入信号的稳态视觉诱发电位信号.通过实验确定了叠加平均次数与最佳视觉刺激颜色,并对混合闪光刺激下SSVEP的提取进行了研究.实验结果表明,该方法提取出的SSVEP信号能够反映使用者的控制意图,可应用于脑-机接口系统.

关 键 词:稳态视觉诱发电位  脑-机接口  脑电

Abstract:For acquiring steady state visual evoked potential(SSVEP)applied to brain-computer interface system,a method combining average and FFT is proposed.Input signal are obtained by their frequency figure of SSVEP.Times of average and best color of visual stimulation are confirmed by experiments.A method of acquiring SSVEP with mixed visual stimulation is studied.Experiments showed that SSVEP can reflect the control purposes of users and can be applied to BCI system.
Keywords:steady state visual evoked potential(SSVEP)  brain-computer interface(BCI)  electroencephalogram(EEG)
