About Face: The Essentials of Interaction Design, 4th edition
By Cooper, Alan
Book – 2014
Many years ago in the mid-’90s, Alan Cooper wrote the first edition of this leading UI design book. Its revelation for me was the concept of automatic save. When you are using, say, a word processor, you normally want to save before closing. So that is automatic, and if you want otherwise then you have to ask for it via some menu or control. There are never confirmation dialogs saying “are you sure you want to …”. Instead, there is an undo function which can reverse any action when you want to go back.
