P300-based BCI mouse with genetically-optimized analogue control
IEEE transactions on neural systems and rehabilitation engineering, 2008•ieeexplore.ieee.org
In this paper we propose a brain-computer interface (BCI) mouse based on P300 waves in
electroencephalogram (EEG) signals. The system is analogue in that at no point a binary
decision is made as to whether or not a P300 was actually produced in response to the
stimuli. Instead, the 2D motion of the pointer on the screen, using a novel BCI paradigm, is
controlled by directly combining the amplitudes of the output produced by a filter in the
presence of different stimuli. This filter and the features to be combined within it are�…

This filter and the features to be combined within it are optimised by an evolutionary algorithm.
