The Design of Everyday Things
Cognitive scientist Don Norman's provocative 1988 classic argues that when users make mistakes, it's never their fault and always the designer's fault, proposing that design serves as communication between object and user. The book introduces foundational concepts including affordances (what actions are possible), signifiers (clear indicators of how to interact), feedback (informing users of action outcomes), and the gulf of execution (gap between intentions and allowable actions). Norman's rules are simple: make things visible, exploit natural relationships coupling function and control, and make intelligent use of constraints—establishing discoverability and understanding as the most important characteristics of good design.
