Not so long ago, if I wanted to adjust the heat in my car, or the volume on my car radio, I could grab a nice, simple knob.
- Turn it to the right, and the car got warmer, or the radio got louder.
- Turn it the other way, and the opposite occurred.
I could always sense how far I was adjusting things—without ever taking my eyes off the road—because millions of years of evolution have produced a neurological feedback mechanism that lets me know just how much I'm turning my wrist.
Easy, effective, intuitive.
Easy, effective, intuitive.
That's simply good design, right?
You'd think...
