| Research Abstract |
Seeing from a baseball batter, the angular velocity of a ball thrown at 140km/h reaches as high as 1000deg/s. However, batters can hit the ball. This indicates good ability of recognition in baseball players. In this study, we analyzed eye-movement-recognition system in elite baseball balayers. Results indicates that they have high miximum speed of eye-movement, but the recognition at a given retinal slip is comparable to that of non-players. Furthermore, we analyzed what kind of information batters use, utilizing shatter googles. Interestingly, batters use visual information in the period till only 150ms after the ball release.
