There is an intriguing book about design mistakes that can maim or even kill, and how to avoid them. It discusses the roles and responsibilities of designers, the battle against dumb mistakes and users, and how design can infuriate and exclude human traits and flaws. This is “Tragic Design” by Jonathan Shariat and Cynthia Savard Saucier, a 220-page book written in English. The book is worth reading; it’s incredibly interesting. For example, in the second chapter, “Design Can Kill,” four situations are analyzed where product interface errors led to fatal consequences. Situation 1: A radiation therapy device that “shot” patients with a beam of 17k rad, 85 times the standard dose. Situation 2: A ferry where the gas and brake pedals switched places depending on the mode. Situation 3: A car that locked its doors and caught fire from a rear-end collision, killing at least 180 people. Situation 4: An airplane that crashed into a mountain because it confused degrees with vertical speed.
