I guess I might've been a bit unclear, then. The info that they got was obtained after pulling up a submenu. I'd make a mockup, but I'm shit with wireframes.

In essence, the 'players' view the world as we do our reality; it's only when they consciously pull up the interface do things change. I guess a close comparison would be, like, Google Glass?

I hope that's a bit clearer. Once the stuff is visible, then... You know, info.
