网球运动员观看网球静态图片时的眼动特征

Eye Movement Features of Tennis Players Watching Tennis Static Images

采用美国应用实验室生产的ASL-H6头戴式眼动仪,对20名专业网球运动员和30名网球专项大学生在观看网球静态图片时的眼动特征进行研究,对两组不同水平网球运动员的首个注视点时间、注视点个数、平均瞳孔直径、注视点平均注视时间、注视顺序、注视轨迹进行分析,发现:(1)在观看网球图片时,专家运动员与新手运动员的视觉搜索特征存在显著性差异;(2)专家运动员的注视点平均注视时间少、平均瞳孔直径小、注视点个数少;(3)专家运动员的注视轨迹简单集中,特别是在注视顺序上有一定的策略性,而新手运动员的注视轨迹复杂,注视顺序比较随意,没有任何的加工策略。

Adopting ASL—H16 Eye Movement Measure system produced by an American applied Laboratory,this paper researched into the eye movement features of 20 professional tennis players and 30 university students major ing in tennis when they watched tennis static images and analyzed the first attention time,the number of attention points,the average pupil diameter in fixation,fixation duration in zone,attention sequence and attention track.The research results were as followings：（1）When watching tennis pictures,the visual search features of expert athletes and novice athletes were significantly different.（2）Expert athlete＇s fixation point average fixation time and the num ber of attention points was less,average pupil diameter was small.（3）The attention track of expert athletes was sim ple and centralized.They had some strategies especially in attention sequence.However,the attention track of nov ice athletes was complicated and the attention sequence was causal.They had no strategies.
