More about VR:
Sometimes you get "stuck" and cannot walk.... think this relates to virtual keyboard.
Sometimes virtual keyboard.... is in the way of what you are typing.
Sometimes virtual keyboard.... cannot be got rid of.
VR interface should be resolution independant. If I play in highest resolution, interface is reasonably discreet. If I play 1280 by 900 or whatever.... interface is... always in the way of what you are looking at.
