Ergonomics is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimise human well-being and overall system performance.” International Ergonomics AssociationThe terms ‘ergonomics’ and ‘human factors’ can be used interchangeably, although ‘ergonomics’ is often used in relation to the physical aspects of the environment, such as workstations and control panels, while ‘human factors’ is often used in relation to wider system in which people work. On this site we generally use the term that fits most closely with the research or the industry that we are discussing. Ergonomics is a science-based discipline that brings together knowledge from other subjects such as anatomy and physiology, psychology, engineering and statistics to ensure that designs complement the strengths and abilities of people and minimise the effects of their limitations. Rather than expecting people to adapt to a design that forces them to work in an uncomfortable, stressful or dangerous way, ergonomists and human factors specialists seek to understand how a product, workplace or system can be designed to suit the people who need to use it.
