Eye Movement Characteristics Of Badminton Players Rebounding The Ball In Realistic Scene

In this study,the badminton rebounding technique was used as the content material,and the experimental test was carried out in the real situation.The eye movement characteristics of the testees in the process of judging the killing route were analyzed,and the high level(secondary level or above)was compared.The difference between eye movement characteristics between ordinary athletes and ordinary college students,in order to provide a theoretical reference for scientific badminton training methods and means.In order to achieve the combination of eye movement index and different scenarios,the experimental method was adopted: 2(group: high-level group and ordinary group)×3(route: straight line killing,slanting killing and indefinite point killing)× 6(area of interest: ball,head,badminton racket,arm,leg and shoulder-chest).Inter-group variables: group;intra-group variables: route and region of interest.Dependent variables: Eye movement indicators included the number and duration of fixation.Combining with the methods of literature,mathematical statistics and other methods,this paper makes a theoretical analysis and discussion of the research object,and a comprehensive research design using a variety of research methods.The following conclusions are drawn:(1)There were significant differences in the number and duration of gaze between subjects of different levels in different interest areas.The high-level athletes observe their legs more and stay longer than the low-level students.It shows that high-level athletes have rich badminton competition experience and long-term training to form a better visual search model.(2)There are significant differences between the regions of interest in different situations.In the line of receiving and killing,more observations were made on badminton and arms,and few visual searches were conducted on the head.The mostattention was paid to the ball in the middle of the slanting line and the indefinite point,followed by the shoulder and chest,and the least attention was paid to the racket and head,respectively.Because of the simplicity of the scene and the fast speed of the short ball in the line,the subjects used the most direct method to carry out visual search in a small area.In complex situations,they need to expand the visual search and concentrate on the necessary areas of interest to extract effective information quickly.
