An oncoming interactive platform integrated with LCD provides another option not only for handicapped but public to make our daily lives more convenient. Steady-state visual evoked potentials (SSVEPs) are human brain responses to visual stimulation at specific light flashing frequencies. With the improvement of brain-computer interface (BCI) applications in mind, this paper proposed effective and comfortable SSVEP stimuli of high-frequency and polychromatic encoded lights with tunable duty cycles and phases.
