BCI Spellers for end-users utilize numerous different techniques, but many require that stimuli in different areas of the screen be foveated for best performance. Spatial independence, however, is of considerable value for patients suffering from locked-in syndrome, which significantly attenuates their capacity for voluntary movements. To this end, we have designed a 10-segment library of letter subsets, which combinatorially create the letters of the alphabet. Segments can thus be centrally presented, allowing letters to be cued in parallel while maintaining the spatial independence of RSVP-style spellers. A 68% segmentclassification accuracy yields a reasonably rapid speller, with several avenues for maximizing accuracy and information transfer rate.
