Research On The Eye Movements Of Different Horizontal Basketball Referees In The Process Of Arbitration

The experiment by the IView X series RED desktop eye tracker Germany S MI company design and manufacturing, with 28 different level of basketball refer ees as subjects, on key regional gaze between different levels of basketball referee s, times of fixation time, fixation track etc. comparative analysis of characteristics of eye movement, pay attention to explore the different strategy level of basketb all referees visual. The visual search behavior and prediction ability is the main in dexes of observation; long-term training can improve individual visual attention str ategy. Relevant data shows, in the people to obtain external information, 80% ~ 90% is obtained through visual organ. Eye movement is the first step of visual inf ormation acquisition, information processing and on subsequent plays an extremel y important role. Human visual search mode is a kind of selective attention, the existence of two kinds of typical visual search mode: pay attention to search and s election of. The search for specific performance of attention in visual search, pay attention to the choice of manifests specifically in the visual search strategy, so me eye movement data such as fixation point, watching the time is very sensitive to the. So, can be measured by the people of eye tracking eye movement of peo ple’s visual attention model.The results showed that:(1) present the material in different position, the three groups of participants of th e obvious differences between judgment accuracy. The high level subjects and low l evel group was tested in a correct judgment rate significantly.(2) present the material in different position, the obvious differences between the t hree groups of participants of the key reaction. The high level group was tested an d the middle level group was tested in a key reaction significantly; the low level g roup and the middle level group, the high level group on a key reaction when the re was no difference.(3) present the material in different position, the three groups have significant differences in the head, leg ball, number of fixations on region of interest. The high le vel group and low level group, the medium level group in the head region of inte rest in the number of fix actions significantly; three groups of subjects ranging f rom differences exist in the bulbar region of interest on the number of fixations; h igh level group and low level group watched in the leg region of interest were sig nificant difference. And the three group of subjects there is no significant differe nce in the hand, in vitro, the number of fixation on the shoulder region of interes t.(4) present the material in different position, the three groups have significant diff erences in the hand, head, in vitro, bulb, leg and shoulder fixation time. The high le vel group and low level group, the medium level group in the hand region of int erest of the fixation time significantly; high level group and low level group in th e head region of interest, in vitro looking time significantly difference; high leve l group and the middle level group in the bulbar region of interest as the injectio n time is the three groups were significant; there are differences in the leg, should er region of interest of the fixation time.(5) present the material in different position, the three groups of participant s in the much watched difference lies in the degree wide field of vision on the tr ack and round trip times.The results show that, different positions show material, by the referee level i nfluence, group son foul judgment, the high level group was the highest rate of co rrect judgment, key reaction the fastest on the specific region of interest, the num ber of fixation, fixation time is more concentrated, look more widely.
