Multi-command SSVEP-based BCI system via single flickering frequency half-field stimulation pattern.

Multi-command SSVEP-based BCI system via single flickering frequency half-field stimulation pattern.

This paper proposes a half-field steady state visual evoked potential (SSVEP)-based brain-computer interface (BCI) system to enhance the number of limited commands obtained from the existing SSVEP-based BCI methods. With the theory of vision perception and the concept of the existing half-field SSVE...
