What is the explanation of ergonomic terms?

The so-called ergonomics refers to the application of anthropometry, human mechanics, labor physiology, labor psychology and other disciplines of research methods.

It studies the structural and functional characteristics of the human body and provides the structural parameters of the human body, such as size, weight, body surface area, specific gravity, center of gravity, and the relationship and accessible range of various parts of the human body during activities.

It also provides the output range of various parts of the human body, exercise habits and other human functional parameters, and analyzes the functional characteristics of human sensory organs such as vision, hearing, touch and skin feeling. Analyze physiological changes, energy consumption, fatigue mechanism and people's adaptability to various labor loads; This paper discusses the factors that affect people's psychological state at work and the influence of psychological factors on work efficiency.

The salient features of ergonomics:

The remarkable feature of ergonomics is that, on the basis of carefully studying the characteristics of human, machine and environment, people who use "things" and designed "things" and the environment where people and things coexist are studied as a system, rather than simply focusing on the quality of individual elements.

In ergonomics, this system is called "man-machine-environment" system. In this system, the interaction and interdependence among human, machine and environment determine the overall performance of the system. The theory of man-machine system design of this subject is to scientifically use the organic relationship among the three elements to seek the best parameters of the system.
