It has been an important topic which sport psychologists keep studying to use scientific laboratory apparatus to search for athletes' eye movementfeatures. According to the research,volleyballers' eye movement timing features and spatial features can be accurately recorded instantly by using the eyemovement recorder,and the eye movement recorder is an effective instrument to reflect volleyballers' visual features. In this research,the ASL Eye Tracker6000 was used for research on the visual search focus point and eye movement features in smashing action graph of volleyball players of different skill levels, try to explore the intrinsic cognitive rules of visual search in the volleyball smashing movement graph by volleyballers,and providing theoretical references forscientific training in volleyball playing,psychological selection and proper use of skills and tactics and others. It is found that(1)the average fixation time, total fixation time,the average saccade distance,the average saccade speed and the diameter of the pupil of eye movement indices in each period of high-lev-el athletes were higher than the low level athletes. The fixation point number of high level athlete in the address period was larger than that of the low level ath-letes.(2)the average fixation duration of high level and low level players in different period ball contrasted significantly,total fixation time on the ball and theball between period was very significant,the average saccade speed difference in the take-off phase and a phase contrast significantly,the fixation point num-ber in the ball during the period,the average contrast significantly difference the pupil diameter in the differences between the three period contrast is quitesignificant.(3)the judgment correctness of high-level volleyball players was significantly higher than that of low-level with significant difference. It meansthat high-level volleyball players have acquired the ability to visually search for action information stably,accurately,and effectively and the ability to quick-ly process information and make correct decisions.
