彩色和高频cVEP-based BCI范例
Chromatic and High-frequency cVEP-based BCI Paradigm
摘要:
我们目前的结果的方法代码调制的视觉诱发电位(cVEP)的脑机接口(BCI)的范例,使用四个高频闪光刺激。与最先进的基于cVEP的BCI相比,为了产生更高频率的刺激,我们建议使用由我们团队设计的小型微控制器板硬件发生器驱动的发光二极管(LED)。在研究中使用高频和绿-蓝彩色闪光刺激,以最大限度地减少光敏性癫痫(PSE)的危险。我们比较了基于绿-蓝彩色cVEP的BCI精度与传统的基于白-黑闪烁的接口。
英文摘要:
We present results of an approach to a code-modulated visual evoked potential (cVEP) based brain-computer interface (BCI) paradigm using four high-frequency flashing stimuli. To generate higher frequency stimulation compared to the state-of-the-art cVEP-based BCIs, we propose to use the light-emitting diodes (LEDs) driven from a small micro-controller board hardware generator designed by our team. The high-frequency and green-blue chromatic flashing stimuli are used in the study in order to minimize a danger of a photosensitive epilepsy (PSE). We compare the the green-blue chromatic cVEP-based BCI accuracies with the conventional white-black flicker based interface.
