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

Table 3

Results of the driving performance. Total time each subject required for steering the MRC through the route (15 meters and 10 turns including camera movements). 26 correct commands (3 commands in camera mode and 23 commands in drive mode) were necessary to complete the task. Accuracy (Acc) is the number of correct commands (26) divided by the total number of commands (). Mean values are given at the bottom of the table.
