Abstract

It is demonstrated that spectral characteristics of steady-state visual evoked potentials (SSVEPs) in a brain-computer interface (SSVEP-based BCI) depend significantly on the stimulus parameters, such as color and frequency of its flashing light. We postulate these dependencies can be used to improve the BCI performance – by proper design, configuration and adjustment of the visual stimulator. Preliminary results of conducted experiments show also that SSVEP characteristics are strongly affected by subjects biodiversity.
