A VEP-based spelling system with sequential stimulus using binary BCH codes

It is known that electroencephalograph (EEG) signals show specific responses with a event; e.g., visual stimulus, cognition or motor imagery. Especially users can control an electronic device by classifying and interpreting the EEG signals; such a system is called brain-computer interface (BCI). In this study, we tried to construct the BCI system, based on transient visual evoked potentials (VEPs) and its visual stimuli flash in conformity with the sequence of binary Bose-Chaudhuri-Hocquenghem (BCH) codes.
