Actually, with the animations - they'll need to look around (i.e. not just stare at one place) as they press buttons, whilst sitting or standing, and also while they are idling at their posts. This will create the effect that they are looking at their consoles and all the instruments and stuff.
In the picture above, I have their heads moving about as they look at their consoles, the main screen and each other.
