Why do volume controls place the down button on the left and the up button on the right?
I'm mostly interested in the horizontal button placement, not the more popular vertical placement.
Where this becomes problematic for me, is in my car. I always press the opposite volume button than what I am expecting/wanting!
On my steering wheel, the top row is the volume control and the bottom row is for cycling through stations/CD tracks.
Every volume slider I have seen also has less volume on the left and more volume on the right.
Why not place the up-volume button on the left?
Is this just because someone made this design choice a long time ago and it stuck? Are horizontal controls actually bad and they should be vertical? Do our brains intuitively think left is down or decreasing?
My left thumb sure doesn't understand.
For the record, I am left-handed.
