A SSVEP-BCI with random moving stimuli in simulation environment

In this paper, a brain-computer interface (BCI) paradigm based on steady-state visually evoked potentials (SSVEP) with stimulus targets' number change is designed to simulate the effects of BCI when used in the field of moving objects recognition and tracking. Stimulus' number, path and the target are created at random in each trial. Experimental results show that the paradigm is usable, and there is no a clear decline in the correct rate. This provides a basis for study of the target detection in real environments, and raise a desired for new evaluating indicator.
