The Design of Everyday Things
Why this book?
I’m into timeless, universal truths, and this book opened my eyes to the fundamentals of user interfaces all around me. Finally, I understood why the faucets at my in-law's guest bathroom seemed to work backwards, and why no one could open the huge glass doors at that Santa Clara hotel on the first try. I love that easy-to-use interfaces are based on a few common principles that are easy to learn and remember. A warning, though, you will evaluate and judge every bad user interface you come across for the rest of your life. And, I expect, you will not design any of those.
