Abstract

A technique of half-field alternate visual stimulation, combined with differential EEG signal measurement, is applied to acquire steady-state brain-evoked signals. Taking the difference of two signals, measured with properly placed electrodes, enhances the visual-evoked potential (VEP) and suppresses the noise components. An array of different-flash-frequency light-emitting-diode (LED) pairs forms a multiple-choice table. By fixating at different LED pairs, the user communicates (by the VEP of corresponding frequency) his/her decision about the selection of the table entry.

基于ssvep的脑机接口交替半场刺激技术

采用半视场交替视觉刺激与差分脑电信号测量相结合的方法获取稳态脑诱发信号。利用两个信号的差值，在适当的位置测量电极，增强视觉诱发电位(VEP)，抑制噪声成分。一组不同闪烁频率的发光二极管(LED)对形成了一个选择题表。通过注视不同的LED对，用户(通过相应频率的VEP)传达他/她对表项选择的决定。
