Someone whose oppinion I listen to, Karsten Lentzch, recommends these books about user interface design:

Jeff Johnson: GUI Bloopers: Don’ts and Do’s for Designers
Ellen Isaacs: Designing from both sides of the screen
Mullet: Designing Visual Interfaces

Background: I went to a couple of presentations by Karsten Lentzch at JavaOne. He is the author of an impressive Java/Swing user interface library, called JGoodies. I’ve been using his stuff in BlogBridgefrom almost the very start so it was good to meet him face to face.

In fact it was basically a go-no go question for me on using Java for BlogBridge: “Can a beautiful user interface be built with Java?” In the end, I discovered JGoodies and decided that it was possible, and so decided to go with Java.
