The Design of Everyday Things: A Review

Introduction

In his book, The Design of Everyday Things, Don Norman argues that good design is not just about aesthetics, but also about usability. He believes that products should be designed to be easy to understand and use, and that they should fit the needs of the people who use them.

Norman's Principles of Good Design

Norman identifies seven principles of good design:

1. Affordance: The affordances of an object are the clues that indicate how it can be used. For example, a button affords pressing, while a door handle affords pulling.
2. Signifiers: Signifiers are the cues that tell us what an object is and how to use it. For example, a red stop sign signifies that you must stop, while a green arrow signifies that you can go.
3. Mapping: Mapping refers to the relationship between the controls of an object and the actions that they produce. For example, in a car, the steering wheel is mapped to the wheels, so that turning the steering wheel turns the wheels.
4. Feedback: Feedback is the information that an object provides to the user about how it is being used. For example, when you press a button, the button may make a clicking sound or light up to let you know that it has been pressed.
5. Conceptual models: Conceptual models are the mental models that users have of how an object works. For example, most people have a conceptual model of how a car works, which allows them to drive it without having to think about every little detail.
6. Constraints: Constraints are the limitations that affect how an object can be used. For example, the size of a button constrains how easy it is to press.
7. Errors: Errors are the mistakes that users make when using an object. Norman argues that errors are not always the fault of the user, and that designers should take steps to minimize the likelihood of errors.

The Importance of Good Design

Norman argues that good design is important for a number of reasons. First, good design makes products easier to use, which can save time and frustration. Second, good design can make products more enjoyable to use, which can lead to increased satisfaction and loyalty. Third, good design can help to prevent accidents and injuries.

Conclusion

The Design of Everyday Things is a must-read for anyone interested in design, usability, or human-computer interaction. Norman's insights into the psychology of design are invaluable, and his principles of good design can be applied to a wide range of products and services.

If you are looking for a book that will change the way you think about design, then I highly recommend The Design of Everyday Things.
