A brain computer interface (BCI) would provide “locked-in” patients that have lost all voluntary muscle control the ability to communicate again with their surrounding. By controlling the computer only with brain activity the study set out to create a faster spelling device than the Hex-o-Spell. Traditionally, imagined movement is used to create control in an EEG-based BCI system. Usually, these are thoughts about left and right hand movements. The Hex-o-Spell application from the Berlin BCI group was modified in the current study by adding a third thought (imagination) to the CSP-based classification. Unfortunately the Berlin BCI record of 7 character per second wasn’t broken because of project time constraints but a promising third brain signal was found to create a faster spelling device for BCI: the beta rebound is reliably detected in one subject and further study needs to confirm the usability of this signal.
