Research On The Visual Search Characteristics Of Football Players In Open And Closed Motor Skill Scenarios

The feeling of vision is the most important access to obtain outside information.In the field of sport psychology,the effective information which the visual system extract can reflect the difference among athletes searching features.This study using the visual search strategy research which is relatively mature eye movement technology to explore search features of football players in the open and closed motor skills scenarios visual.Contributing to the study of the cognitive psychological ability training and providing some useful references.Usung new Dikablis Pro eye glasses type instrument released by Germany Ergoneers,to analysis the difference between fixation point and time for different groups of athletes and to explore the visual features of athletes who have different levels with open and closed movement skills scenarios.Using the method of data mining to analysis inner link between eye movement indicators and predicting accuracy.It can providing theoretical basis for improving the ability of footballer visual search.(1)Based on the analysis of open motor skill scene,two groups of had significant difference of the visual identity,thus it has affected the accuracy of the judge.No matter under the condition of fixation time or the proportion of the number subjects who have high scores all concenrate on their teammates,the central area closed to the goal in or defensive players.Compared with low-scores group,the high-score group on watching rob players and defensive players are more than the low-score group.(2)According to the analysis of closed motor skill scene,the reasons for judging are as follows:,the high-scores group watch more on the trunk,head and legs than the low-score group.From the ratio of s,there is obvious difference between the two groups in the selection of fixation time.High-scores group watch more on head,legs,football and players than the low-scores group.(3)According to the data mining method,the correlation rules of eye-movement index of the high-score group and the judgment score of 5 points in the open sports skill scene are: watching the torso,head and ball;watching feet and ball.(4)According to the data mining method,the correlation rules of eye-movement index of the high-score group and the judgment score of 5 points in the closed sports skill scene are :watching middle of the football gate and teammates.(5)It can be seen from the correlation rules that if the correct visual search strategy is applied,even the football players with weak sports cognition can be judged accurately.
