For all entries, numerator is number of seizures and denominator is total number of seizures analyzed.
One patient had an aura while playing the video game but output variables could not be analyzed due to technical problems.
Two partial seizures were analyzed by video/EEG review but could not be analyzed by video game output variables because of technical problems.
Steering, throttle and car velocity were not analyzed for one partial seizure because the patient was stopped from playing by a family member. However, there was one collision before this happened.
Two absence seizures were analyzed by video/EEG review but could not be analyzed by video game output variables because of technical problems. Reproduced with permission from Yang et al [38].
