Analysis of eye movement and visual recognition ability in elite baseball players

从棒球击球手的角度看，以140公里/小时的速度抛出的球的角速度高达1000度/秒。然而，击球手可以击中球。这说明棒球运动员的识别能力较好。在本研究中，我们分析了优秀棒球运动员的眼动识别系统。结果表明，他们的最大眼球运动速度很高，但在给定的视网膜滑动时的识别能力与非玩家相当。此外，我们分析了什么样的信息使用，利用粉碎谷歌。有趣的是，击球手在球释放后仅150毫秒的时间内使用视觉信息。

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.
