HUMAN ENGINEERING

Summary from the TLDR Design newsletter

Human engineering is a multidisciplinary field focused on designing systems, technologies, and environments that make correct actions intuitive and errors difficult, rather than relying on training or willpower. This article illustrates this through everyday examples like stovetop configurations and "Norman Doors," demonstrating how poor spatial compatibility and discoverability lead to common mistakes that stem from design failures rather than human error. By applying principles such as natural mapping, affordances, and constraints, human engineering reduces cognitive load and creates systems where ordinary human performance produces excellent results at minimal cost.
