The new examples and ideas about design and product development make it essential reading. Don Norman is Distinguished Professor Emeritus of Cognitive Science and Psychology and founding director of the Design Lab at the University of California, San Diego. Business Week has named Norman one of the world's most influential designers. He was an Apple Vice President, has been an advisor and board member for numerous companies, and has three honorary degrees. His numerous books have been translated into over 20 languages, including The Design of Everyday Things and Living with Complexity, also from the MIT Press.

Conscious attention is needed to learn new things. But when users repeatedly perform tasks/actions over a period of time, they perform those same actions subconsciously. It’s important designers communicate the results of an action. Feedback when an action is performed must be immediate and informative. Delayed feedback can be disconcerting and lead to user abandonment or failure.
Conceptual Models.
For instance, Norman’s famous in the design community for becoming the enemy of any door that an ordinary Joe might have difficulty figuring out how to get through. “The worst of them,” Kripalani says, “we now call ‘Norman Doors.’” Like, doors with a flat surface that looks like it should be pushed, but which you actually have to pull, or doors with revolving handles that don’t actually unlatch the door. In this chapter, Don Norman explains further how mental models[knowledge in the head] helps users interact with a product. It allows us make quick judgments(responses) about the environment subconsciously without conscious awareness. Great designers use aesthetic sensibilities to drive visceral responses.
Designing for Error
We use that knowledge while interacting with new things. Anil Kripalani, who’s running Norman’s contest, says there’s real hope it will attract some great ideas. “Don Norman champions ‘human-centered design,’” he says.

Even the smartest among us can feel inept as we fail to figure out which light switch or oven burner to turn on, or whether to push, pull, or slide a door. The fault lies in product design that ignore the needs of users and the principles of cognitive psychology. Knowledge in the world includes perceived affordances and signifiers, the mappings between the parts that appear to be controls or places to manipulate and the resulting actions, and the physical constraints that limit what can be done. Knowledge in the head includes conceptual models; cultural, semantic, and logical constraints on behavior; and analogies between the current situation and previous experiences with other situations.
They are used when a product’s affordances are not easily perceived. Some signifiers are signs, labels that tell the users what to do. Discoverability — Is it possible for users to figure out what the possible actions are to use that product?. Norman uses case studies to describe the psychology behind what he deems good and bad design, and proposes design principles.
A design that people do not purchase is a failed design, no matter how great the design team might consider it. Novices are more likely to make mistakes than slips, whereas expects are more likely to make slips. Mistakes often arise from ambiguous or unclear information about the current state of a system, the lack of a good conceptual model, and inappropriate procedures.
Chapter 6: Design Thinking
Too much feedback can be annoying and irritating to users. Too little feedback can be as useless as no feedback at all. Feedback also needs to be prioritized (important messages/alerts vs. unimportant). Poor feedback can be worse than no feedback at all, because it is distracting, uninformative, and in many cases irritating an anxiety provoking. When users make mistakes using a product or when a product fails, designers should strive hard to determine what the cause is. One of the methods we can use to determine what the underlying cause of failure is to make use of the “Root Cause Analysis” method.
Part operating manual for designers and part manifesto on the power of designing for people, The Design of Everyday Things is even more relevant today than it was when first published. A fully updated and expanded edition of Don Norman's classic and influential work, which pioneered the application of cognitive science to design. Design is successful only if the final product is successful — if people buy it, use it, and enjoy it, thus spreading the word.
Now fully expanded and updated, with a new introduction by the author, The Design of Everyday Things is a powerful primer on how — and why — some products satisfy customers while others only frustrate them. Limitations in application or use that can help with the formation of conceptual models. Affordances are the possible actions a person can perform with a particular object/product. If an affordance cannot be easily perceived by a user, a means of signaling it’s presence is required. User-centered design involves simplifying the structure of tasks, making things visible, getting the mapping right, exploiting the powers of constraint, designing for error, explaining affordances, and seven stages of action.
When new technologies emerge, there is a temptation to develop new products immediately. How can businesses create innovative products that users will love without considering the users mental models. There are two forms of product innovation; Incremental Innovation(less glamorous, but most common) and Radical Innovation(most glamorous, but rarely successful). An example of radical innovation is Apple launching an all touchscreen smartphone in a time when phones still had physical keys.
The book spans several disciplines including behavioral psychology, ergonomics, and design practice. Don Norman is a co-founder of the Nielsen Norman Group, and holds graduate degrees in both engineering and psychology. His many books include Emotional Design, The Design of Future Things, and Living with Complexity, and The Design of Everyday Things.
He went to great lengths to define and explain these terms in detail, giving examples following and going against the advice given and pointing out the consequences. Makes a strong case for the needlessness of badly conceived and badly designed everyday objects.... [T]his book may herald the beginning of a change in user habits and expectations, a change that manufacturers would be obliged to respond to. As the pace of technological change accelerates, the principles in this book are increasingly important.
