the layout of buttons or controls aren't what makes something usable without looking. being familiar with the product is what makes it usable without looking. no matter what kind of button layout you have, you're still going to have to look at it. i've had a car pc over the last two years and i still have to look and see what i'm trying to touch.
The only way you could setup a control interface that would not require visual aid would be to ( in this situation):
Break the screen into six quadrants:
1. Top inch or 20% of the screen functions as the up button
2. Bottom inch or twenty ""
3. Left ""
4. Right ""
5. Center of the the screen functions as the "Pause/Play" button
6. have a inch square out of one of the corners act as the menu button(being customizable to any of the four corners. just in case any of your crazy brits that drive on the wrong side of the road want a little support. ;-) j/k)
honestly i don't think something like this is a bad idea, but this is reason i'm against it? 2 of them:
1. it's against the law for me to be using it in my car, while driving, in LA. So therefore i'm stopped so i might as well look at it.
2. About 10% of the reason i even have it in my car is for "Functionality", the other 90% is for the "Holy *****!!" effect.
