FEEDBACK VISUALIZATION INFLUENCE ON A BRAIN-COMPUTER INTERFACE PERFORMANCE


This paper presents our progress in development of a brain computer interface. We used existing system which was extended to support synchronous experiments with feedback. We use the simplest possible methods as we focus on feedback influence. We examined influence of the way how the feedback is visualized. The abstract feedback, the feedback based on computer game, and the feedback showing real photographs were tested. The classification score 88.5% was achieved with one subject even with simple classification method.

Keywords:
BCI, Real-time processing, feedback
