Motion onset visually evoked potentials (mVEPs) allow users to interact with technology using non-visually fatiguing stimuli in a brain-computer interface (BCI). This study employs mVEP for brain controlled computer games and evaluates players ability to use mVEP for online gameplay with games from three different genres namely action, puzzle and sports. Five mVEP stimuli are presented as buttons to allow the subject to choose from five possible actions in each game. The performance was assessed based on offline and online BCI accuracy and game score. The results indicate that the players could control the games with reasonable online accuracy (65{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} average for 5 class classification, with an average training accuracy of 74{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}). The study also found that players did noticeably better in the sports game (bowling) than other game genres in both online BCI testing and game playing scores.
