Analysis Of Eye Movement Characteristics Of Badminton Special College Students In The Process Of Judging The Return Point Of The Net

Badminton sport is a fast rhythm,tactics and changeful,fast attack and defense conversion of sports,athletes in a short time to make quick strokes reaction,its speed,route,placement,and the technical consistency of movement and other factors.Anticipation ability is very important in the badminton sport,to improve the badminton technology and tactics,cognitive ability of badminton,must be strengthened in a short period of time to look at reasonable position and technical movement,so as to improve the forecasting ability.This research adopts the research,\ "experts-novice\" paradigm in experimental method to participants were college students on the net return set judgment in the process of eye movement characteristics were analyzed,and the comparison between the two groups had no quantity,average fixation time,fixation point DE,the diameter of the pupil,fixation frequency,placement accuracy and reaction time,linear ball and slash accuracy and reaction time of the eye movement characteristics indexes,the analysis of the differences between the two groups of subjects level.Experimental study to obtain the following results:(1)the panel participants and novice group of participants in the fixation point number has very obvious gap,shows that action of the panel participants to obtain the information ability is higher than the novice group.From total fixation time long,the panel participants will be limited time to pay more attention to the possible ball placement and the line of key information for the priority.(2)the panel participants average saccadic distance is greater than the novice group.In A,B two video key information of target selection and visual search and view of broad has A direct relationship between the amount of information,thus affecting the panel participants analysis accuracy result in the panel participants judgment correctness.(3)the panel participants pupil diameter changes than novice group participants,illustrate the panel participants in A,B two important parts of athletes in the video information search and extract the information efficiency is significantly higher than the novice group.(4)the new group of participants to look at frequency is greater than the panel participants,illustrate the panel participants of A,B two video irrelevant information and classify information about screening process,strengthen the attention to the related information search,so as to reduce the frequency of watching.(5)on the placement accuracy and reaction time,the expert group is right to try to improve the accuracy,i.e.,according to the extension of the reaction time on the premise of guarantee accuracy improving.Professional review for accuracy and reaction time in both A and B in the period of video is greater than the novice group.(6)ball in a straight line with the cross time and the reaction time,the panel participants accuracy and reaction time were higher than that of the novice group participants accuracy and reaction time;Straight ball judgment accuracy and reaction time were higher than the cross accuracy and reaction time.
