Neural Correlates of Relevant Stimuli Processing for Brain Computer Interfaces

Acqualagna, Laura ;   Blankertz, Benjamin

The transfer of Brain-Computer Interface (BCI) technology to non-medical application in Human-Computer Interaction (HCI) such as Information Retrieval (IR) systems requires the development of novel experimental designs and classification approaches that cope with a richer variety of stimuli than usual fundamental laboratory studies. The present study aims at identifying neural correlates that indicate the relevance of a perceived stimulus to the participant wrt her/his current task. Such implicit information about the user state decoded online could be used in future HCI applications complementary to the explicit input.
