It wasn’t just aesthetics. It was survival distilled into guidelines—how a single symbol could shorten reaction times in a control room, how standardized signals could prevent a cascade of errors when languages and cultures mixed.

IEC 60073, also known as "Basic and safety principles for man-machine interface (MMI), marking and identification – Part 1: General principles," provides guidelines for designing HMIs that are intuitive, easy to use, and minimize the risk of human error. The standard covers various aspects of HMI design, including visual and auditory signaling, marking and identification, and ergonomic principles. It was survival distilled into guidelines—how a single
