In this paper, eye tracking of a referee in a Kendo match was conducted to gather the information on his eye movement and visional field. The kendo match with referees was performed to characterize the eye movement of the referee and to investigate the influence of his eye movement to his judge. A calibration-free eye tracker device, EMR-ACTUS, and a wearable camera, HX-A1H, were employed to correct the information on visual field of the referees and to record their eye movement. The number of strikes in the match was counted, and the strikes were categorized into three stages for evaluation. It was found that the umpire watched the middle part between players during the whole match. The gaze point did not vary depending on the number of effective strikes and regular strikes. Additionally, it was found that the gaze rate to a player decreased in the case of a low-rated evaluation regarding strikes.
