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.

Over the period of time technology is bringing changes and innovations to make our life easier. Devices are getting complicated as they are stacked with lots of options. The main challenge for designers is to bring the same technology that simplifies life by providing more functions in each device. In design, the secret to success is to understand what the real problem is. We often rush to solve a problem without questioning whether or not we are solving the right problem. HCD(Human Centered Design) is a procedure for addressing these requirements but with an emphasis on two things; solving the right problem and doing so in a way that meets human needs.

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.

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.

The lesson here for businesses is to focus on strengths of their products, not to follow their competitions blindly.

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.

Not all knowledge required for precise behavior has to be in the head. It can be distributed — partly in the head, partly in the world, and partly in the constraints of the world. This is where deep understanding develops, where reasoning and conscious decision-making take place. In this chapter, Don Norman talks about the most important characteristics of good design which are discoverability and understanding. Designers need to make things that satisfy people’s needs, in terms of function, in terms of being understandable and usable, and in terms of their ability to deliver emotional satisfaction, pride, and delight.
An example is a door; a door handle helps a user “discover” what action is possible, while a pull or push sign helps the user “understand” what to do with that door handle, which direction the user should push or pull it. Your payment method will be charged immediately, and the product is expected to ship on or around November 5, 2013. This date is subject to change due to shipping delays beyond our control. The cumulated insights and wisdom of the cross-disciplinary genius Donald Norman are a must for designers and a joy for those who are interested in artifacts and people. Knowledge in the world is usually easy to come by. Signifiers, physical constraints, and natural mappings are all perceivable cues that act as knowledge in the world.
HCD is an iterative problem solving process that designers use, it includes stages such as Observation(Research & Understanding of the problem), Idea generation, Prototyping and Testing. It is the relationship between the elements of two sets of things. The relationship between a control and it’s results are easiest to understand when there is an understandable mapping between the control and it’s results. Controls should be close to the items been controlled. For example, light switches in hall are usually arranged in such a way that a user will immediately know which switch controls which light. Signifiers help users know what affordances a product has and how to use them.
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.
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.
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.
