In this study, we investigated the visual search strategy of receivers in volleyball, using their judgments of courses for toss and spike. Fifteen subjects participated in this experiment and their years of experience are 8.6±2.2 yrs., and their ages are 20.5±1.1 yrs. We set up a scene from the toss-up of a setter to hitting spikes of attacker and took it as an exhibition movie which was in a state close to practice. Subjects were ordered to decide whether they should receive the ball or not, as soon as possible, for the receiver defending the area of the back center. Eye movements and the point of time that they took to decide were recorded. As a result, all subjects used saccadic eye movement expeditiously when moving from a setter to an attacker, but judgment time was not rapid. Then, we supposed to that subjects judge the course of toss and spike by getting a key from the ball trajectory. |
