ergonomics
INTRODUCTION
The word "Ergonomics" comes from two Greek words "ergon," meaning work, and "nomos" meaning "laws." Today, however, the word is used to describe the science of "designing the job to fit the worker, not forcing the worker to fit the job." Ergonomics covers all aspects of a job, from the physical stresses it places on joints, muscles, nerves, tendons, bones and the like, to environmental factorswhich can effect hearing, vision, and general comfort and health. Ergonomics is about designing for people, wherever they interact with products, systems or processes. We usually don’t notice good design (unless perhaps, it’s exceptional) because it gives us no cause to, but we do notice poor design. The emphasis within ergonomics is to ensure that designs complement the strengths and abilities of people and minimise the effects of their limitations, rather than forcing them to adapt. In achieving this aim, it becomes necessary to understand and design for the variability represented in the population, spanning such attributes as age, size, strength, cognitive ability, prior experience, cultural expectations and goals. Qualified ergonomists are the only recognised professionals to have competency in optimising performance, safety and comfort. Practitioners study how people interact with products, processes and environments day to day in order to improve them, to make them easier to use, safer, more comfortable, more efficient. They take into account and apply relevant research to help with this and to suggest recommendations. But none of this can happen without a thorough knowledge and understanding of the users and their experiences.

Repetitive Strain Injuries occur from repeated physical movements doing damage to tendons, nerves, muscles, and other soft body tissues. Occupations ranging from meatpackers to musicians have characteristic RSIs that can result from the typical tasks they perform. The rise
