The term "User-Centered Design" was coined by Rob Kling in 1977 and later adopted in Donald A. Norman's research laboratory at the University of California, San Diego. The concept became widely popular as a result of the publication of the book "User-Centered System Design: New Perspectives on Human-Computer Interaction" in 1986. The concept gained further attention and acceptance in Norman's seminal book "The Design of Everyday Things" (originally called "The Psychology of Everyday Things"). In this book, Norman describes the psychology behind what he deems 'good' and 'bad' design through examples. He exalts the importance of design in our everyday lives, and the consequences of errors caused by bad designs.
