Driving a Semiautonomous Mobile Robotic Car Controlled by an SSVEP-Based BCI

Figure 8

Track for the mobile robotic car. Subjects had to steer the MRC through a 15-meter-long course with 10 turns in order to reach the finish line. At a certain turning point (marked with a blue square), the MRCs camera faced a text message that instructed the subject to switch to camera mode. The task was to examine the surroundings and to look for a hidden number which was attached underneath a drawer (otherwise not visible). One example of the optimal path is shown in Figure 9.
