how many buttons do the vive controllers have for use in game? I think there are some that bring up the camera view, or the steam overlay, so what are usable for games? I know that 'less is more' but hoping it at least has more than just the trigger and side grips?
Just triggers (dual stage) grips, and touchpad (which in itself can have all kinds of modes and functions). They decided everything should be gestural or a physical interaction with the VR world as opposed to button abstracting actions, which definitely makes a ton of sense to me.
