With a halfway decent hotas stick/throttle setup and a keyboard with the little bumps on F and J keys, you won't need to see the keyboard. Or get a custom programmable accessory gaming keyboard to map specific commands to the gaming accessory keyboard.
With my old Saitek hotas, I almost never had to touch the keyboard. If you're buying an oculus rift setup, you can certainly afford a decent programmable stick/throttle...
