A study of stimulation methods in visual evoked potential based brain-computer interface

Recently, a lot of researchers have studied the brain-computer interface (BCI) system, and some systems have already been put to practical use. For instance, the system based on P300 were actively used. However the P300 system requires user´s strong concentrations. Therefore it is necessary to introduce information from the EEG signal. This paper tried to investigate a rhythmic after-discharge of transient-VEP by consecutive visual stimulation, and now have examined responses to a variety of stimulation methods.
