Don Norman has earned his title as the “Father of User Experience” because:
He coined the term “user experience,” commonly known as “UX,” and defined it as follows: “‘User experience’ encompasses all aspects of the end user’s interaction with the company, its services, and its products.”
He defined and developed the concept of “user-centered design” (UCD) and later evolved it into “human-centered design” (HCD).
He wrote The Design of Everyday Things (DOET) (originally The Psychology of Everyday Things (POET)), a landmark book on usability and human-centered design.
He has introduced and popularized several essential UX design principles, such as affordances, signifiers, and the three levels of emotion.
He co-founded the influential user experience consulting and research firm Nielsen Norman Group (NN/g) with Jakob Nielsen.
He is an accomplished academic and lecturer in cognitive science, computer science, and psychology and has influenced the inclusion of UX in many educational programs.
User-centered design (UCD) is an approach that focuses on user needs, preferences, and difficulties and puts them at the center of the design process. UCD helps designers create products that align with, resonate with, and delight their users.
Don introduced the concept of user-centered design in his book with co-author Stephen Draper, User-Centered System Design: New Perspectives on Human-Computer Interaction. He later dropped the “system” part and expanded on the approach in his pivotal book, The Design of Everyday Things.
The definition and processes of UCD have evolved over time, and after DOET was published, Don began to call it “human-centered design.” HCD seeks to humanize users by calling them “people” instead of the dehumanizing “users.”
Don explains UCD, HCD, and their evolution in this video:

https://en.wikipedia.org/wiki/Ed_(text_editor)#/media/File:Ed_lines.jpgHuman-centered design consists of these four principles:
Human-centered: Focus on all the people who will interact with your design and the contexts in which they will interact with it.
Define the right problem: Always try to solve the root problem, not just the symptoms. If you solve the root problem, the symptoms will disappear.
Everything is part of a system: Consider the big picture and where your design fits into it. If the goal of a system is for people to get to their destination on time, then a ticket machine user interface (UI) design must contribute toward this goal.
Take small, simple steps: Continuously prototype, test, and iterate each component of a design or system to ensure it consistently meets people’s needs.
In 1988, Don Norman released his book The Psychology of Everyday Things. Publishers later renamed it The Design of Everyday Things to better represent and market its contents. In DOET, Don says design should align with human psychology to make products intuitive and user-friendly. This approach allows people to understand and interact with everyday objects easily.
Don Norman revised and expanded his bestselling book, originally titled “The Psychology of Everyday Things,” in 2013. The revised edition includes Don’s evolution of UCD to HCD and introduces signifiers, among other updates. All versions feature the “Coffeepot for Masochists” on the cover—an aesthetically pleasing design with zero usability.

DOET is a groundbreaking book that tops many recommended reading lists for both beginner and experienced designers. In DOET, Don introduced several foundational principles and definitions to the world of UX design. These include:
7 Principles of Design: In DOET, Don introduced six fundamental principles of design that aim to make products and systems easier to use. They do this by examining how people interact with the world around them. Don later added a seventh principle, signifiers, in the updated edition of DOET. The principles are:
Visibility: Ensure users can easily see essential elements so they know what actions are possible.
Feedback: Provide users with immediate responses to actions to confirm the outcomes and guide them.
Constraints: Limit the actions users can take to prevent errors and show them the correct usage.
Mapping: To support usability, create a clear relationship between controls and their effects.
Consistency: Use familiar elements and patterns to make interactions predictable and understandable.
Affordances: Design objects to suggest their use and help users know how to interact with them intuitively.
Signifiers: Provide clear cues or indicators that guide users on how to interact with elements and where actions should take place.
Affordances: Of Don’s principles, affordances and signifiers, in particular, have been widely discussed and adopted in UX design. An affordance is an inherent quality of an object that suggests its function. For example, a door handle affords pushing or pulling—its appearance suggests what you can do with it. Psychologist James J. Gibson introduced the term “affordance” in the late 1960s, and Don adapted it for design.
Signifiers: A signifier communicates the function of an object. In the door example, a label that says either “push” or “pull” clarifies the action you can take. The term “signifier” originated in semiotics, and Don adopted it for design.
7 Stages of Action: This model describes how people interact with products in a goal-oriented cycle. The seven stages help designers create intuitive products, guide users smoothly through each stage, and make every interaction more satisfying.
They form a goal. For example, a user decides to send a message to a friend.
They form an intention. The user intends to open the messaging app and type out their message.
They specify an action. The user plans to tap the app icon, open the conversation, type the message, and press “send.”
They execute the action. They tap the app icon, open the chat, type the message, and press “send.”
They perceive the state of the world. They see a confirmation (for example, a “sent” checkmark) appear next to their message.
They interpret the state of the world. They understand the checkmark means the app has sent the message successfully.
They evaluate the outcome. They reflect on whether sending the message fulfilled their initial goal of communicating with their friend and consider if any further action is needed.
Don Norman has had a varied and successful career across multiple industries. He began in academia, transitioned to industry, founded a company, and then returned to academia.
Much of Don’s success has stemmed from his cross-disciplinary academic career. He began his academic journey at Massachusetts Institute of Technology (MIT), where he graduated in 1957 with a Bachelor of Science in electrical engineering. He then earned a Master’s in electrical engineering from the University of Pennsylvania.
Next, he shifted his focus to psychology and earned a Ph.D. in 1962 from the University of Pennsylvania. Norman’s interdisciplinary interests led him to positions at Harvard and then the University of California, San Diego (UCSD), where he served as a professor of psychology, cognitive science, and computer science.
Don is a prolific speaker and lecturer who has presented at many conferences across multiple disciplines. In this image, he speaks at the INTERACT IFIP Conference in London, England, in 1984. As of the 2020s, Don no longer gives talks but prefers to host discussions. He finds discussions more valuable to the audience as he knows his responses will interest them.

At UCSD, he co-founded the Institute for Cognitive Science and became a leader in human-computer interaction (HCI) and user-centered design. His research during this time focused on human cognition, usability, and the psychology of everyday interactions. This research laid the groundwork for DOET and began his influence in the world of design.
Don transitioned from academia to industry and joined Apple Computer in 1993 as an “Apple Fellow.” This position was very high in the company, and it allowed Don the freedom to do as he wished. He noticed Apple’s reputation for excellent usability was beginning to fade and made it his mission to change this. Don collaborated with Tom Erickson and Harry Saddler to form the “User Experience Architect’s Office,” and Don became a “User Experience Architect”—the first instance of “user experience” in a job title.
Thanks to Don’s and the group’s work, Apple placed user experience at the same level as marketing and engineering in their product development process. This achievement led to a strong focus on UCD within Apple. When Don’s boss, the Advanced Product Group Vice President, was promoted, Don assumed the vacant role until he left the company.
After he left Apple, Don formed the Nielsen Norman Group in 1998 with usability expert Jakob Nielsen. NN/g is dedicated to enhancing the field of user experience and helping companies design human-centered products. The company also produces evidence-based research and provides industry-recognized training and UX certification.
Don Norman (right) and Jakob Nielsen (left) are two prominent voices in UX, usability, and human-centered design. NN/g’s research has strongly influenced how designers understand user behavior today. Their work has especially affected web and mobile experience design.

Don returned to the University of California, San Diego, in 2014 to become the founding director of The Design Lab, an interdisciplinary research center dedicated to advancing human-centered design. The lab seeks to promote design thinking as an approach to problem-solving across industries. Its work has focused on:
Human-computer interaction
Large-scale education
Automation
Healthcare
Visualization of complex phenomena
Public health
The future of work
Ethical concerns of growing importance
In this video, Don Norman explains the role that design and designers can play in tackling wider social issues:
Don retired from UCSD in 2020 but remains a leading voice in user experience, cognitive science, and design. He serves on multiple advisory boards, hosts discussions at conferences and events, and launched the Don Norman Design Award and Summit (DNDA) in 2024.
DNDA is a worldwide platform for new designers and educational groups to show projects that positively impact society. The award also organizes an international meeting for all groups working to improve society through humanity-centered design.
In this video, Don explains the idea and purpose behind the awards:
In addition to the above, Don Norman has:

A “Norman Door” is a door that does not clearly indicate whether the user should push or pull it. Norman Doors often result in users pushing when they should pull, or vice versa. Don Norman begins his book, “The Design of Everyday Things,” with this famous example to show what happens when designers do not employ user—or human-centered design.
Learn more about Norman Doors and the lessons they offer in this video:
Don Norman’s three levels of design are:
Visceral: The user has an immediate, sensory reaction to a product’s appearance and feel.
Behavioral: The user experiences the product’s interaction and functionality during use.
Reflective: The user finds more profound meaning and personal value in the product.
In his book Emotional Design: Why We Love (or Hate) Everyday Things, Don introduced the three levels to help readers understand how people experience products.

Don Norman envisions a future where UX and technology design become more human-centered, sustainable, and ethically responsible. He believes designers must shift their focus from standalone products to systems that serve society at large. In his view, the traditional boundaries between design, engineering, and social sciences will continue to blur. Designers will develop a multidisciplinary approach where they play a vital role in shaping technology’s impact on humanity.
Don also stresses the importance of accessibility and inclusivity in design. Designers must ensure their products cater to diverse needs across different demographics. He highlights the ethical responsibility designers hold, particularly as AI, automation, and machine learning increasingly influence daily life. According to Norman, in the future of UX, designers must anticipate the societal implications of technology. They must prioritize user empowerment, privacy, and long-term sustainability over short-term gains.
In this video, Don Norman explains why and how designers must change for a better world:
The Design of Everyday Things by Don Norman is beneficial for designers at any stage of their careers. This essential book talks about:
Human-centered design principles.
How and why products should be easy to understand and user-friendly.
Fundamental design principles, such as affordances, feedback, and constraints, which help designers understand how users interact with objects in real life.
The book is especially valuable for designers who want to improve usability and create designs that feel natural to users. Norman’s insights help designers avoid common mistakes, such as designing products that look good but confuse or frustrate users.
Watch this video to understand affordances, an essential concept from DOET:
According to Don Norman, the two most important features of good design are discoverability and understanding. These essential principles help designers create products users can use and enjoy without feeling confused.
Discoverability refers to how easily users can find and recognize a product’s functions. In well-designed systems, users should be able to figure out how to operate each feature themselves. For example, elevator panels with clearly marked buttons immediately show which button to press for each floor. Discoverability ensures users can interact with design elements easily and confidently.
Understanding is about helping users predict how a product will respond when they use it. A good design matches the user’s way of thinking and allows them to anticipate what will happen. For instance, door handles that clearly indicate whether to push or pull give users an instant idea of how to interact with them. Designers who design for understanding reduce user frustration and create a smoother, more enjoyable experience.
