摘　　要：基于VC平台的脑电拨号系统利用12个按不同频率闪烁的LCD刺激模块,诱发产生稳态视觉诱发电位,并在O1通道提取出来,在上位机上用数字带通滤波器和功率谱估计对脑电信号进行滤波、特征提取和模式分类后产生12个控制命令进行拨号。通过7位受试者各10次实验验证,本系统能够正确拨打11位的手机号码并通话,拨打成功率最高达到100%,平均正确率98%,平均时间低于59 s,证明该系统的方案可行且具有较高的应用价值。An EEG dialing system based on VC platform is designed in this paper, which induces steady-state visual e- voked potentials according to the results of 12 LCD flashes at a different frequency and extracts the signal at the O1 channel. By using digital band pass filter and power spectral estimation to deal with the SSVEP filtering and feature extraction, 12 commands to dial calls are produced. Through 10 times experiments for seven subjects respectively, this system can make the calls get through correctly and the highest success is 100%, and the average accuracy is 98% and the average time be- low 59 s, which confirmed the reliability and high application value of the system.
