Emotional Design

Donald A. Norman, a cognitive scientist and the author of The Design of Everyday Things, opens with the story of three teapots he owns: an intentionally unusable "coffeepot for masochists" (3) by French artist Jacques Carelman, a charming "Nanna" teapot by architect Michael Graves, and a practical "tilting" teapot by the German firm Ronnefeldt. He uses none daily, preferring a simple metal brewing ball, yet keeps them on display because each carries personal meaning and illustrates a different dimension of design. Norman introduces the book's central framework: Visceral design concerns appearance, behavioral design concerns the pleasure and effectiveness of use, and reflective design concerns self-image, personal satisfaction, and the stories objects allow us to tell. He argues that the emotional side of design may matter more to a product's success than its practical elements.

Norman acknowledges that in The Design of Everyday Things, he focused on utility without accounting for emotion, producing the criticism that following his prescriptions would yield usable but ugly designs. He now aims to reconcile usability with aesthetics and emotion. He distinguishes between affect, the general judgmental system operating whether conscious or subconscious, and emotion, the conscious experience of affect with an identified cause and object. Citing neuroscientist Antonio Damasio's research on patients with brain injuries impairing their emotional systems, who appeared normal yet could not make decisions effectively, Norman establishes that emotion is essential to rational decision making.

In Chapter 1, Norman presents evidence that attractive things work better. Japanese researchers Masaaki Kurosu and Kaori Kashimura found that attractive automated teller machine (ATM) layouts were perceived as easier to use even though all versions were functionally identical, a finding Israeli scientist Noam Tractinsky replicated with even stronger results. Norman explains these findings through psychologist Alice Isen's research showing that people in positive moods are better at creative thinking and problem solving. Attractive designs induce positive affect, broadening cognition and making users more tolerant of minor difficulties, while anxiety narrows focus and causes people to repeat failed strategies.

Norman then introduces three levels of brain processing, developed with colleagues Andrew Ortony and William Revelle: The visceral level handles automatic, prewired responses; the behavioral level governs learned everyday behavior; and the reflective level enables conscious thought and self-awareness. These levels correspond to evolutionary development and sometimes conflict with one another. A roller coaster pits visceral fear against reflective pride, and fire exits require outward-opening "panic hardware" because panicked people push on doors even when they must be pulled. Norman presents lists of conditions producing automatic positive affect (warm places, sweet tastes, bright colors, symmetrical objects) and negative affect (heights, sudden loud sounds, darkness, sharp objects), noting these are genetically influenced visceral responses, though some require experiential triggers.

Chapter 2 explores the multiple dimensions of emotion and design. Norman argues that no single product can satisfy everyone and that market segmentation is necessary. He turns to objects that evoke memories, arguing that lasting emotional attachment comes not from surface appearance but from personal history and association. He discusses souvenirs, which the design world dismisses as kitsch but which serve as powerful emotional triggers, and examines photographs, whose emotional power is so great that people rush into burning homes to save them. He explores how self-image drives product choices and recounts the Betty Crocker cake mix story: The original mix required only water and failed because consumers felt no involvement, but adding an egg restored pride in the baking process, demonstrating that emotional connection can matter more than a product's intrinsic value. Norman addresses the personality of products, fashion as a shifting reflective-level phenomenon, and brands as emotional signifiers, concluding Part I by affirming that all three processing levels yield equally critical forms of design.

Chapter 3 details the practical application of each design level. For visceral design, Norman discusses evolutionary preferences for symmetry and smoothness and the immediate emotional impact of appearance. For behavioral design, he identifies four components: function, understandability, usability, and physical feel. He emphasizes observing real users in natural environments and explains the importance of conceptual models, illustrating good design with Mercedes Benz seat controls whose physical arrangement mirrors the seat parts they adjust. For reflective design, he visits Swatch in Switzerland, where executives explain that Swatch is an "emotions company" that transformed watches into fashion statements. He presents a case study of a Motorola headset designed for National Football League (NFL) coaches, where the biggest challenge was making coaches feel good wearing the device, projecting a heroic self-image while also functioning effectively. He discusses the "devious side of design" in retail environments and concludes by arguing that iterative testing works well for behavioral design, but visceral and reflective design benefit from a single designer's clear vision.

Chapter 4 examines fun, pleasure, music, film, and video games. Norman visits MIT Professor Hiroshi Ishii's laboratory, experiencing playful interactive installations that demonstrate how technology can bring richness and enjoyment to life. He applies Julie Khaslavsky and Nathan Shedroff's framework of seduction (enticement, relationship, fulfillment) to Philippe Starck's "Juicy Salif" citrus juicer, a design so striking that its gold-plated anniversary edition explicitly warns against contact with acidic fruit. He examines Jon Boorstin's analysis from The Hollywood Eye, which identifies three emotional levels in film (visceral, vicarious, and voyeur) corresponding to Norman's three processing levels, and argues that the best films balance all three. He concludes with video games, arguing that they represent a new genre with powerful educational potential.

Chapter 5 examines anthropomorphism, trust, and communication. Norman illustrates the human tendency to attribute emotions to inanimate objects and discusses trust as essential to cooperative interaction. He turns to communication technologies as emotional tools, presenting survey responses revealing deep attachment to Instant Messaging and arguing that cell phones are fundamentally social instruments. He addresses the problems of always-on connectivity, noting that hands-free phones prove just as dangerous as hand-held ones while driving because the distraction stems from the conversation itself.

Chapter 6 argues that machines will need emotions for the same reasons humans do. Norman envisions home robots communicating with one another and their owners, and argues that robots will need emotions such as fear, fatigue, surprise, frustration, and pride to function effectively. He insists that emotional displays must be genuine reflections of internal states rather than fake expressions. He describes MIT's Kismet, a socially interactive robot designed by Professor Cynthia Breazeal, and discusses Rosalind Picard's Affective Computing research on sensing human emotions through physiological measures.

Chapter 7 examines the future of robots through Isaac Asimov's four Laws of Robotics, evaluating each against existing technology and finding partial implementations in safety sensors, automatic braking systems, and energy-monitoring systems. Norman discusses the benefits of emotional machines in dangerous tasks, driving, education, and medicine. He argues that while technology's development is inevitable and beneficial, problems of inequity must be confronted as human problems rather than technological ones.

In the Epilogue, Norman reports results from an informal internet survey showing passion across all three design levels, with the strongest enthusiasm for communication services enhancing social interaction. He argues that true personalization cannot be manufactured; it comes from lived experience and the gradual accumulation of marks and memories that transform mass-produced objects into personal belongings. He concludes that we are all designers who choose, arrange, and restructure the objects in our lives. Professional designers can create attractive, functional products, but only the individual can make something personal through the emotional bonds that develop over time.
