Like with the Wadsworth-BCI, the Graz-BCI also works with mu- and beta-rhythm to drive either a cursor on a screen, a neuroprosthetic device, or even the natural muscles by functional electrical stimulation. Examples for the latter two cases are given in the picture (more) and on the Graz-BCI-video.

The Graz-BCI works with the users producing images of movement in their imagination. With Thomas, the paralysed person on the video, his orthosis opens on an imagination of a right-hand-movement and closes on the imagination of a foot movement.
In a long training period, the EEG-data from the sensorimotor cortex are used to establish user specific algorithms from the electrical activity caused by the "imagination". The Graz-group around Gert Pfurtscheller has also developed a remote control telemedicine system (see second picture) for the training sessions to be performed from home (more).
