The Study On Eye Movements Of Basketball Referees In China

Basketball is a sport that is extremely defensive and has a fast pace of attack and defense transition.In a rapidly changing basketball court,basketball referees need to judge the actions of players on the court through eyes observation in fierce physical confrontation and offensive and defensive transitions.The complex and changing situation on the court not only requires the referee to have keen observation,but also needs to transmit the visual information to the center of the brain through the visual receptors,and then make the correct judgment through the referee's own theoretical reserves and quick judgment.In the course of a basketball competition,basketball referees are required to “judge immediately” and “judge accurately”,that is,to instantly discover and judge illegal actions,thereby stifling any hidden dangers in the initial stage.However,due to the fast movement,frequent rhythm changes and the diverse movement paths of basketball players,the referee must have a clear understanding of the situation on the court as soon as possible,and form a judgment basis through scientific and reasonable observation areas and paths,so as to make a correct judgment.Therefore,the referee should have a solid theoretical foundation,a reasonable range of vision and an accurate glance path.Only in this way can the referee make an accurate judgment in the fast changing competition,so as to provide a fair and just competition environment and improve the quality of the competition.The purpose of this study is to examine the differences in on-court observations of basketball referees at different levels during on-the-spot judgment by using eye movement technology to observe the first visual angle video.In the experiment,30 basketball referees of various levels in China are selected,of which the international and national group is the international and national basketball referees(n = 10),the national first-level group is the national first-level basketball referee(n = 10),and the national second-level and third-level group are the national second-level and national third-level basketball referees(n = 10).The experiment records the reaction time and eye movement information of the participants when watching the experimental video.The experiment examines the differences in response time,accuracy rate,focus area and scan path of basketball referees at different levels on the court,and then explores future referee training methods.The experimental task is to ask the subject to judge by observing events on the court and to punish the segments that need to be judged.Based on the experimental results and related discussions,the main conclusions of this study are as follows:1.Basketball referees with higher level have faster response times and higher accuracy rates.2.There are significant differences in the performance of the three groups of basketball referees in the focus area.The high-level referees can observe the responsible area for a long time,while the low-level referees are more distracted and spend a lot of time in non responsible areas.3.High-level basketball referees have a more scientific and reasonable scan path,and can perform dynamic observation according to the referee law requirements,while low-level basketball referees have the characteristics of chaotic sequence and too small or too large range on the glance path.
