Applied Science Laboratory(ASL)produced 504-based eye tracking system,taking 10 professional football goalkeeper and 10 students as subjects for testing goalkeeper to defend the ball a penalty for the exercise scenario fragments,the eye movement of professional goalkeeper dynamic characteristics was made a experimental study to compare the two sets of goalkeeper results of eye movements to explore the goalkeeper the ball in the defensive penalty,the eye movement characteristics of the impact of the decision-making accuracy.The result showed that 1)the ball in the defensive penalty situations,professional goalkeeper and the goalkeeper of the eye movement characteristics of college students was significant difference.2)Professional goalkeeper with a relatively reasonable visual search strategy,look at spots,look at the allocation of primary and secondary clear watching track simple,practical and information more effective.3)The kicker of the supporting leg,swing leg,foot ball determined the direction of the main observation point shooting.In the defense,the focus of attention to these three areas,combined with an analysis of experience-spot judgments could effectively improve the success rate of defending the ball penalty.4)Sports experience level and defensive decision-making was essential for accurate,the higher of exercise level and game experience,the higher of defensive decision-making accuracy rate.
