摘要: The stimuli color greatly affects the performance of a steady-state visual evoked potential (SSVEP)-based brain computer interface (BCI). However, few studies have evaluated effect combination on multiple-target BCI when adopt different colors. In this study, 16 sets colors were tested by using an online dual-task BCI, and detection accuracy, time information transmission rate (ITR) measured. results showed that yellow-red achieved highest shortest ITR, which is optimal choice for improving BCI.
