when i try to remember a poem my brain creates images and i walk trough
them, when i reproduce it. when i learn a piece of music it does other
stuff (i'm a pianist and singer) but in the end i have a very complex
thing in my mind, just think of a bach fugue. i have the fugue also in
"the fingers". different areas of the brain work together. i have the
same oppinion as you, we are very good in using a visual UI. we trained
it for a long time. but there could be other combinations that work
nearly as good as "mouse-to-eye".

i think it's all a matter of training. you do the
"display-keyboard-mouse-combination" for long years and you became
professional in speed and precision. watch a pro-gamer gaming with
mouse.. what's about data-gloves? whats with feet-controlers and other
"non-standard" devices?
