The Impact of Vision on Batting Performance in Baseball
The experiment examined the effect of vision on batting in baseball, utilizing liquid crystal glasses with electronic shutters in different conditions. Results showed that closing the shutters either 150ms after release or prior to arrival had no significant impact on hitting effectiveness. This supports the hypothesis that the last 150ms of visual information doesn't provide useful data for batters. Real-life examples, like Mariano Rivera's cutter pitch, reinforce the importance of timing in baseball performance.

2. Eyes Wide Shut ---Batting and Thinking Hitting is fifty percent above the shoulders See Bob Adair, The Physics of Baseball 1
The Experiment Batters hit from pitching machine (FB & CH) Liquid crystal glasses with electronic shutters Three conditions NO: shutter open for full trajectory R+150: shutter closed 150 ms after release A-150: shutter closed 150 ms prior to arrival High-speed cameras recorded location of impact on bat, with goal of hitting on sweet spot 2
Typical Trajectories R+150 A-150 See Michael Richmond http://sonsofsamhorn.com/baseball/batting/visual-analysis- batting/how-do-hitters-perform-with-their-eyes-wide-shut/ 3
Results R+150: batter is much less effective A-150 same as NO Conclusions Last 150 ms provides no useful information Adair hypothesis confirmed Batter could just as well close his eyes R+150 A-150 NO 4
A Real-Life Example: Mariano Rivera s Cutter 150 ms 150 ms 5
