P300 visual speller based on random set presentation
2014 International Winter Workshop on Brain-Computer Interface (BCI), 2014•ieeexplore.ieee.org
Event-related potential (ERP)-based P300 spellers are commonly used in the domain of
brain-computer interfaces as a communication pathway for the impaired. In this paper, we
propose a novel stimulus representation pattern for the P300-based visual speller. In
contrast to the classical matrix speller, in this new approach users see a unique combination
of letters in each stimulus during a given sequence. Our results indicate that this change
increases information transfer rates (ITR) for all four considered subjects.
