Abstract :
This paper investigates the safe movement of pathfinder robot in a Virtual Environment (VE) comprising fixed and moving obstacles only by using electroencephalogram (EEG) signal. In the proposed system, users can choose the movement destination using P300 evoked potential and also change the velocity to react to the moving obstacles in the real time. The experimental results of system evaluation on four healthy male persons illustrate its ability to move different objects by handicap users.
