This story came out a couple days ago, describing the use of virtual reality for batting practice by the Tampa Bay Rays. The team is using a simulator called the iCube through which players can take swings against a virtual pitcher that mimics a variety of human MLB pitchers.
I would love to see the perspective that the batter himself has in using the system. Without a doubt, the experience would be far more realistic than the one I have taking batting practice against my Wii (and certainly much more difficult). It’ll be fascinating to see how technology like this will ultimately impact training and the game itself.
