The ASL Eye Tracker 6000 eye movement recorder is used for experimental research on the visual search focus point and eye movement features in smashing action graph of volleyball players of different skill levels. It is found that( 1) during take-off,high-level volleyball player focus on more points on trunks than low-level do; while throwing the ball while the high-level volleyball player also focus on less points on trunks than low-level do; but while hitting the ball,the high-level volleyball player focus on more points on the trunk than beginner ones do,and the difference above is very significant;( 2) during the three phases,the frequency for high-level volleyball player to focus on the upper limbs tends to equally rise with significant difference.( 3) High level athletes' invalid points of fixation and back fixation points are significantly less than those of low level athletes with significant difference.( 4) the judgment correctness of high-level volleyball player is significantly higher than that of low-level with significant difference. It means that high-level volleyball player have acquired the ability to visually search for action information stably,accurately,and effectively and the ability to quickly process information and make correct decisions.
