The glasses are just for screen&sound. Controlling is done by the controller, Including a slider for accurate actions, like zooming in, accelerating just to a specific point and so on; by the two motion-sensors more realistic movements can be done. And of course you can watch movies & listen to music.
The perfect way of playing games in school without being recognized ;P And if you want to pause, just turn the screens transparent, so you see trough it !
