What is Ergonomics?• Wojciech Jastrzebowski (1857), a Polish scholar

was the first to define and use the concept of "ergonomics".

• He described it as: "The Science of Work", deriving the word 'ergonomics' from the Greek words ergon, meaning work, and nomos, meaning principle.

• A more recent definition of ergonomics is:The science concerned with designing safe and comfortable machines for humans.http://www.webopedia.com

Ergonomics• Ergonomic design is the application of body

knowledge to the design of tools, machines and environments for safe effective human use.

• Besides computer hardware, ergonomics also encompasses air quality, room temperature, work environment cleanliness and office furniture.

• All of these elements can and often do affect a person's ability to do their job safely, productively and well.
