Fighting game is one of the video games which 2 players fighting in screen by controlling characters. While skilled fighting game players are perceived to have great reflex or judgment like chess players, there is no precise skill evaluation method. In this paper, we suggested surface EMG signal as fighting game skill evaluation method. In the experiment, we divide 10 subjects into skilled group and unskilled group by inputting trial. Furthermore, we measured EMG of their left arms and derived average rectified value. As a result, there were no significant difference of input power, but were input timing between 2 groups.
