Abstract: According to the brain computer interface (BCI) system requirements of steady-state visual-evoked potential, visual stimulator that based on the Android system is designed with the development platform of Android. The visual stimulator is composed of 12 stimulation modules with different frequencies. The users can represent their intentions by selecting different stimulation modules with different frequency flickers. On the basis of Android visual stimulator, EEG acquisition experiment is designed, and through the experimental verification, we come to the conclusion that visual stimulation can effectively induce the steady-state visual-evoked potential with steady and obvious features, and furthermore verify that visual stimulator has good feasibility and reliability as well as high application value.
