Design is concerned with how things work, how they are controlled, and the nature of the interaction between people and technology.

Now fully expanded and updated, with a new introduction by the author, The Design of Everyday Things is a powerful primer on howand whysome products satisfy customers while others only frustrate them.

The goal: guide the user effortlessly to the right action on the right control at the right time. The rules are simple: make things visible, exploit natural relationships that couple function and control, and make intelligent use of constraints.

The problems range from ambiguous and hidden controls to arbitrary relationships between controls and functions, coupled with a lack of feedback or other assistance and unreasonable demands on memorization. The fault, argues this ingeniouseven liberatingbook, lies not in ourselves, but in product design that ignores the needs of users and the principles of cognitive psychology.
