AB In this paper, an asynchronous brain-computer interface is presented that enablesthe control of a wheelchair in virtual environments using only one motor imagerytask. The control is achieved through a graphical intentional control interface with three navigation commands (move forward, turn right, and turn left) which are displayed surrounding a circle. A bar is rotating in the center of the circle, so it points successively to the three possible commands. The user can, by motor imagery, ex-tend this bar length to select the command at which the bar is pointing. Once acommand is selected, the virtual wheelchair moves in a continuous way, so the usercontrols the length of the advance or the amplitude of the turns. Users can volun-tarily switch from this interface to a noncontrol interface (and vice versa) whenthey do not want to generate any command. After performing a cue-based feed-back training, three subjects carried out an experiment in which they had to navi-gate through the same fixed path to reach an objective. The results obtained sup-port the viability of the system.
