Constructing a brain-computer interface

This contribution presents our advances in development of a real-time EEG processing system. Existing system was extended by common configuration, logging system and new modules including support for both new EEG device and new experiments. Correct function of the system was extensively tested and verified in numerous experiments with several subjects and demonstrated at the faculty open day. Scores of 75% were achieved with classification of left and right hand movement imagery. We use the simplest possible methods as we focus on feedback influence. Difficulties of transition to a real BCI operation along with faced problems are discussed.
