Roger Federer shows you what it's like to play tennis from his perspective

GOOGLE GLASS MAY not be the most purposeful product ever made, but it certainly is entertaining.

People are still trying to find uses for it, though, and it seems the best they can do is to use it to record themselves doing things from their perspective.

In the latest effort to do just this, seven-time Wimbledon winner Roger Federer hits the courts wearing Google Glass, going up against Stefan Edberg to show off some skills.
