Ergonomics (say "er-guh-NOM-iks") is the study of the kind of work you do, the environment you work in, and the tools you use to do your job. It is the science of making things fit people. Ergonomics uses knowledge from the fields of anatomy, mechanics, physiology, and psychology to utilize human energy most effectively. Something that is ergonomic is designed for safe, comfortable, and efficient use. For example, a computer keyboard with an ergonomic design is intended to help the user avoid carpal tunnel syndrome and wrist pain.
