Data from 9 healthy subjects collected during BCI experiments with a visual ERP paradigm
for a photo browser application has been analyzed offline. A comparison of four stimulus presentation
modes revealed that complex highlighting effects composed of brightness enhancement, rotation,
enlargement and a trichromatic grid overlay in combination with row-column spatial arrangements of
simultaneously highlighted objects boosted single subtrial classification performance best.
