New Paradigms for Brain Computer Interface Based on SSVEP

A Brain Computer Interface (BCI) creates a new communication channels for disabled peoples, the classical way of steady-state visual evoked potential (SSVEP) based on (BCI) was focusing on multi-frequency and phases. In this study a novel high-speed SSVEP based on BCI, was implemented a new paradigms of SSVEP, which induced by irregular flickering with phase-tagged toward brain activity response, which effectively mean multiple frequencies combination, which lead to distinguishable brain response, were considered a closed loop system, as off-line analysis, the combining average of stimuli frequency is recommended using FFT. The frequency and feature extracted of electroencephalograms (EEG) were computed to intention detection, in this experimental study, different results between regular versus irregular had been found, represented by high amplitude with respect to conjunctive of stimuli flicker according to a patterns and frequencies.
