The author and other cognitive psychologists have developed a toolkit for analyzing our relations with things. Norman rightly notes a fundamental paradox that informs his work: “The same technology that simplifies life by providing more functions in each device also complicates life by making the device harder to learn, harder to use.” Don Norman’s Design of Everyday Things is a thorough revision of one of the standard general-interest works on human factors, originally published as The Psychology of Everyday Things twenty-five years ago.
