Virtual reality tennis exists in a way through video games, but the big video game networks haven't taken it this far yet. Roger Federer is getting involved with one of the wonder kids of the virtual reality world (the other being the Oculus Rift) Google Glass, to bring forth one of the most insane tennis experiences one can have.
Imagine playing a game of tennis against the greatest player to ever play the game. This isn't just a pipe dream, it's a reality, as Google Glass is letting the average Joe get virtual for a practice session with the Maestro.
For those looking to face off against Federer at virtual Wimbledon, they may be a bit disappointed as the session is only a practice session, but any court time with him is big time.
