Research On Influencing Factors And Optimization Strategies Of Visual Search In The Aiming Phase Of Archery Athlete

Aiming is a crucial stage for archery to determine the performance of the ring target.Since the individual differences of athletes will produce different types of visual search activities,the efficient,reasonable and balanced visual search mode with balanced attention distribution is more conducive to the improvement of athletes’ sports performance.The sports environment of archery is complex,and various factors in the athlete’s own internal and external environment may have an impact on the visual search activities of the archer’s aiming stage.In this study,various factors affecting the visual search of archers in the aiming stage were analyzed,and on this basis,eye tracking experiments were designed and related optimization strategies were analyzed.Through analysis,it is found that the factors affecting the visual search strategy of archers in the aiming stage mainly include the basic health of athletes,basic visual condition,sports experience,competition factors,social factors and target stimulus factors,and taking the athlete’s own body environment as the dividing point,these factors can be divided into internal factors and external factors.Among them,the influence of exercise experience and target stimulus is illustrated by eye movement experiments.The experiment collected the visual search data parameters of the participants through the SR Researh Eyelink 1000 plus eye tracker,designed the experimental process with nested thinking model,and processed the data with the help of Data Viewer Version,and other software.Among them,the sports experience experiment was divided into two groups,the expert and novice paradigm,and the effective data were divided into two groups,the first-level athlete group(N=13)and the second-level athlete group(N=11),and the index data of the longest fixation time,total fixation number,scanning duration and reaction time of the participants of different levels when observing the target ring target were recorded with the help of eye tracker.By allowing the participants(N=24)to observe different types of ring target materials,the eye movement data of the target fixation rate,first fixation point time,first fixation point position,and number of eye jumps were recorded,so as to explore the influence of different types of ring target targets on the visual search of athletes in the aiming stage,and on this basis,the type of ring target that is most conducive to athletes’ visual search and attention distribution balance was found.The results of the study showed that:(1)Among the internal and external influencing factors,psychological factors such as athletes’ own psychological attention distribution and visual attention capture are the key to the visual search activities of archers in the aiming stage.(2)In the face of the same ring target experimental materials,the average maximum fixation time of first-class athletes and second-level athletes was 1085.1518/ms and1264.2727/ms;The longest duration fixation point locations were 1 drop point and 3 drop point outside the 10 th ring line,respectively.The average total number of fixations was 10.6154 and13.1818,and the average reaction speed was 1739/ms and 1943/ms,respectively.As a result,the maximum fixation time,maximum duration and scan duration of the target ring target target by first-class athletes are generally shorter,the longest duration fixation point position is closer to the center of the ring target,the total number of fixations when observing the ring target material is less,and the reaction speed is faster.(3)When athletes observe different types of target ring targets,different colors,different shapes and different specifications of ring targets have different degrees of visual attraction to athletes.In the experiment,the red heart,round and medium-sized ring target can attract the visual attention of athletes,the first fixation point position can be more concentrated in the bullseye area,the red heart target fixation rate is 94.75%,the first fixation time is 865.8333/ms,and the number of eye jumps is 4.3750 times;the target fixation rate of the circular ring target is94.2958%,the first fixation time is 826.2083/ms,and the number of eyebeats is 4.6667 times;the target fixation rate of the medium-sized ring target is 93.1293%.The first fixation time was836.7917/ms,and the number of eye skips was 4.0417 times;the search efficiency was followed by the yellow heart,triangle,and small size ring target material,and the first fixation point position could basically be concentrated in the bullseye area,among which the target fixation rate of the yellow ring target was 93.9795%,the first fixation time was 828.75/ms,and the number of eye jumps was 4.5833 times;the target fixation rate of the triangular ring target material was 92.1583%.The first fixation time was 906.8750 and the number of eye beats was5.2917 times;the gaze rate of the small bullseye was 92.5331%,the first fixation time was815.3750/ms,and the number of eye jumps was 4.9583 times.Among them,the target fixation rate of the green heart was 91.3625%,the first fixation time was 942.1667/ms,and the number of eye skips was 5.0417 times;the target fixation rate of the square ring target material was91.0333%,the first fixation time was 877.2917/ms,and the number of eye-hopping was 5.2778;the target fixation rate of the large-sized ring target material was 91.4625%.The first fixation time was 930.6517/ms,and the number of eye skips was 4.9583.Through the research and summary of the influencing factors of visual search in the aiming stage of archers,the following optimization strategies are concluded according to the conclusions:Standardize the selection standards of archery and increase the index of eye tracking material selection.Strengthen physical fitness training to avoid physical exhaustion restrictions.Enrich the experience of archery training and strengthen visual search routes.Improve the rhythm of archery firing and reduce external environmental interference.Increase the environment for training and improve the ability to resist pressure in the competition.Strengthen the professional level of coaching and avoid the influence of coaching guidance.Optimize and adjust the target ring target to enhance visual attention training.
