Different approaches to Brain-Computer Interfaces have been developed, each one with specific solutions that range from understanding and explaining cognitive functions over communicating with real and virtual environments by thought alone to real-time monitoring of cognitive states. In order to foster the exchanges of innovative and challenging ideas, the 12th International Winter Conference on Brain-Computer Interface aims to encourage overview, in-depth talks, and discussions on the latest research at all levels of BCI research. Its devotion includes invasive recording, semi-invasive ECoG, non-invasive EEG, non-invasive NIRS, and fMRI measurement, and potential combinations of the different methods furthermore advance in data analysis. An informal open discussion will be highly encouraged during its poster session.
