The so-called Graz BCI was one of the first online EEG-based BCIs introduced over 25 years ago. We have developed various applications for this system, including spelling devices, computer games, functional electrical stimulation (FES), and navigation in virtual environments. We have tested these applications in healthy users and several patient populations. We successfully organized eight major international BCI conferences over the last 20 years. Our group was recently involved in the EU project "MoreGrasp" (2015-2018) and Prof. Müller-Putz received the ERC Consolidator Grant "Feel your Reach" (2016-2021).
