According to previous studies, the sense of distance as a visual function is one of the most important indicators of many ball games. The purpose of this study investigated the accuracy of the distance perception to a static target. Participants, age from 19 to 22,consisted of 30 male and 30 female college students. The experimental conditions on the distance to a target consisted of 1, 1.5, and 2.0 times of arm-length from their eyes. There were two conditions on the height of the target. One of them was the height from the floor to an eye and the other was the half of it. After they looked at a target, they were asked to show the same distance to the target by its replacement to another place. The number of the experimental trial was three times for each condition. As a result of MANOVA, there was no significant interaction among these conditions. Furthermore, no significant difference was shown for each condition. These results showed that their visual perception was not related to sex difference, height of a target and the distance to it. It was recommended that a moving object should be used to investigate the accuracy of visual perception for athletes.
