Hybrid Brain Computer Interface Paradigm-A Study
P300 and steady-state visual evoked potential (SSVEP) approaches have been the most common paradigms used
for BCI’s world over. But these do not yield satisfactory results in some subjects. That gave birth to a new approach combining
two or more existing approaches to improve accuracy and ITR for majority subjects. The present study compares an
established hybrid P300/SSVEP BCIs paradigm to a new paradigm in which pictorial stimulus, instead of colour changing, is
adopted for P300 evocation to decrease the degradation on SSVEP strength.
