Abstract
We propose a new multistage procedure for a real-time
brain-machine/computer interface (BCI). The developed system allows a BCI user to
navigate a small car (or any other object) on the computer screen in real time, in
any of the four directions, and to stop it
if necessary. Extensive experiments with five young healthy subjects confirmed
the high
performance of the proposed
online BCI system. The modular structure, high speed, and the optimal frequency
band characteristics of the BCI platform are features which
allow an extension to a substantially higher number of commands in the near future.
