A EEG-based brain computer interface system towards applicable vigilance monitoring

Abstract

Monitoring the changes of vigilance is very important, because decline in the operator's alert is one of the primary causal factors for many accidents. Electroencephalogram (EEG) based brain computer interface (BCI) for vigilance analysis and estimate have been rapidly advanced in recent years. However, there still exist many difficulties and challenges in their application. In this paper, we propose an applicable EEG-based BCI system for vigilance monitoring: the number of record channels could be reduced greatly with considering individual variability in EEG, since the practical BCI is expected to be implemented with a small number of channels. Furthermore, the vigilance model can be constructed according to various application situation. With the dry electrodes we are now developing, the system will be conveniently applied to vigilance monitoring in the future. © 2011 Springer-Verlag Berlin Heidelberg.
