Purpose: The purpose of this study was to investigate the differences of visual search and decision-making on expertise levels of rugby referees. Methods: The participants(n=6) consisted of 3 novices and 3 experts. They were asked to watch the rugby game videos wearing eye-tracking glasses and press a response key in the situation to recognize a foul or to blow a whistle. The videos consisted of two skill types(Ruck, Maul) and three situation types(legal, foul, advantage) were randomly presented, and at the end of the videos participants were asked to express verbally visual focus area. Independent variables were expertise level, skill types, and situation types, and dependent variables were the decision-precision, foul recognition time, decision-making time, visual search(eye movement frequency, fixations frequency, fixation duration ratio), fixation locations, and perceived eye-focus locations. Results: The expert referees made more accurate judgments in advantage situation, took longer decision-making time, and did more effective visual search, compared with the novice referees. In addition, the results on the fixation locations and the perceived eye-focus location revealed that expert referee focused more on attack location, and novice referee focused more on defense locations. Conclusion: The findings suggest that the effective visual search and decision-making training needs to be considered to strengthen refereeing capability, and then that would have a major impact on smooth game operation.
