Abstract
For acquiring steady state visual evoked potential (SSVEP) applied to brain-computer interface system, a method combining average and FFT is proposed. Input signal are obtained by their frequency figure of SSVEP. Times of average and best color of visual stimulation are confirmed by experiments. A method of acquiring SSVEP with mixed visual stimulation is studied. Experiments showed that SSVEP can reflect the control purposes of users and can be applied to BCI system.
