Final answer:
Ergonomics aims to make the workplace safer, improve workers' quality of life, and increase efficiency by optimizing the interaction between people and their working environment, such as through appropriate chair height and posture to prevent strain.
Step-by-step explanation:
The purpose of ergonomics is to reduce stress on the worker's body, safely position the person, promote quality of life, and encourage the use of good body mechanics. Ergonomics, or human factors psychology, involves the study of how to improve the fit between the tools, work systems, and the humans using them. This includes designing office workstations with the correct chair height to maintain good posture, where the center of gravity is above the hips, to avoid back strain and disk damage, and creating environments such as standing desks or cycle desks to promote health while working.
Human factors psychologists are particularly concerned with aspects of an office workstation like the height of the chair. Scientific management aimed to increase workers' efficiency, and ergonomics plays a big role in this as well by improving the interface between technology and people, thus enhancing productivity. In short, ergonomics contributes to a healthier, safer, and more efficient workforce.
