Human factors

Human factors is a term used mainly in the United States. In Europe and the rest of the world, the term ergonomics is more prevalent. Human factors is a profession that focuses on how people interact with products, tools, procedures, and any processes likely to be encountered in the modern world.

Simply put, human factors involves work to make the environment work in a way that seems natural to people. This involves research in human performance and capabilities, anthropometrics, usability, and design. Although the terms human factors and ergonomic have only been widely known in recent times, the field's origin is in the design and use of aircraft during World War II to improve aviation safety.
