虚拟现实有望扩展脑机接口（BCI）原型的可能领域。在 VR 中使用脑电图 (EEG) 信号的大部分工作都集中在脑体驱动控制上，其中使用来自身体和大脑的生物信号。我们表明，当允许受试者在沉浸式虚拟环境中正常移动和行动时，仍然可以可靠地获得和使用认知诱发电位信号。将提出识别红色和黄色停车灯处诱发电位之间差异的单次试验平均准确度为 85%，并讨论未来的方向。
Virtual reality promises to extend the realm of possible brain-computer interface (BCI) prototypes. Most of the work using electroencephalograph (EEG) signals in VR has focussed on brain-body actuated control, where biological signals from the body as well as the brain are used. We show that when subjects are allowed to move and act normally in an immersive virtual environment, cognitive evoked potential signals can still be obtained and used reliably A single trial accuracy average of 85% for recognizing the differences between evoked potentials at red and yellow stop lights will be presented and future directions discussed.
