You can trace the outlines of such patterns, you know how to move your head to get a better view, and you know when you have moved it too far to see the whole keyboard. You can obscure any feature of the keyboard by holding your finger at an appropriate location between it and your eye. And instead of describing the relation between the Intel logo and the 'P' key, you can use your finger to trace a connecting path.
