A brain-computer interface (BCI) transforms signals originating from the human
brain into commands that can control devices or applications. With this, a BCI
provides a new non-muscular communication channel, which can be used to assist
patients who have highly compromised motor functions. The Graz-BCI uses motor
imagery and associated oscillatory EEG signals from the sensorimotor cortex for
device control. As a result of research in the past 15 years, the classification
of ERD/ERS patterns in single EEG trials during motor execution and motor imagery
forms the basis of this sensorimotor-rhythm controlled BCI. The major frequency
bands of cortical oscillations considered here are the 8-13 and 15-30 Hz bands.
This chapter describes the basic methods used in Graz-BCI research and outlines
possible clinical applications.
