Visual Search Features of Tennis Players in the Process of Perceptual Anticipation

In this study,different levels of tennis players were seclected as the research object,their visual search features then being recorded when they viewing video clips of tennis match. The results show that differences exist among levels. The opponent's movement trend was the key area where high level tennis player focused in the process of anticipating. The total visit duration to key areas of interest was the longest,and fixation more stable in high-level tennis players' than other players. According to the characteristics above,we demonstrated that high level athletes' the optimal decision strategy is achieved by extracting a series of available information sources,strengthening the fine processing of key information,ignoring irrelevant information,reducing the internal response latency.
