"Emotional Design" by Don Norman explores how emotion and psychology influence the way people interact with everyday objects. The book delves into the concept that attractive things work better because they make people feel good, which enhances user experience and satisfaction. Norman introduces three levels of design—visceral, behavioral, and reflective—and illustrates how each level affects a user's perception and interaction with products. Through insightful examples, he emphasizes the importance of designing products that not only function well but also evoke positive emotions, leading to a deeper connection between the user and the product.
