Ergonomics is about how people, based on their physical capabilities, can best organize and conduct their activities.
Ergonomics, which is also known as human factors, is a systematic order which is in the process of understanding and improving human communications with types of products, equipment, environments and systems.  
Ergonomics is aimed at developing and applying knowledge and techniques to enhance system performance. It also focuses on the health, safety, and well-being of the individuals involved. The concentration of ergonomics is further taken across work, leisure and other aspects of our daily lives.
history of ergonomics
Ergonomics is the science (and art) of fitting the work environment to the employee (Chad Cooper and Brian H. Kleiner, 2001). The word Ergonomics is derived from the Greek words “
” and
”. “
” means work meanwhile “
” means principles of laws (Evelyn Tan Guat Lin, 1996). These combinations give us the phrase ergonomics, which mean the science of work. Ergonomics is not a new science, although the term has become common lately. Ergonomics seeks to improve the match between the job and man’s physical abilities, information handling and workload capacities. By improving the match between the work environment and the employee, you can expect improved employee comfort, reduced chances for occupational injuries, improved productivity, and improved employee job satisfaction
International Labor Organization (ILO) defines ergonomics as the application of the human biological sciences in conjunction with the engineering sciences to the worker and which at the same time enhances productivity. This definition emphasizes the important triad of ergonomics elements namely comfort, health and productivity. Thus ergonomics seeks to adapt work to human physical and psychological capabilities and limitations. In seeking this goal, it draws on many disciplines including anatomy, physiology, psychology, sociology, physics and engineering (Evelyn Tan Guat Lin, 1996)
objective of ergonomics
Secure health, safety and comfort of persons doing the work.
Improve the comfort and utility of various equipments and facilities, such as furniture and dwelling units, used by people by matching their design with physiological characteristics o their intended users
Achieve better work efficiency and effectiveness

statutory requirements related to ergonomics in OSHA
In the other hand, Occupational Safety and Health Act 1994 (OSHA 1994) has defines ergonomics as the science of “designing the job to fit the worker, instead of forcing the worker to fit the job”. However, generally ergonomics is defines as fitting the job (tools, tasks, and environment) to the employee, instead of forcing the worker to fit the job. Ideally, ergonomics makes the job safer by preventing injury and illness, makes the job easier by adjusting the job to the worker, makes the job more pleasant by reducing physical and mental stress and in the same time it saves money.
Chad Cooper and Brian H. Kleiner define ergonomics as the study of equipment design in order to reduce operator fatigue and discomfort. Also known as human factors or human engineering it basically describes the interaction between an employee and their job functions, with the emphasis being on reducing unnecessary physical stress in the workplace. Ergonomics also can be defines as a discipline concerned with all aspects of designing for people (Ann Brooks, 1998)
Besides that, ergonomics is the practice of learning the practice of learning about human characteristics and then using that understanding to improve people’s interaction with the things they use and with the environments in which they do so 10(Wilson, 1995). Board of Certification for Professional Ergonomists (BCPE) defines ergonomics as a body of knowledge about human abilities, human limitations and human characteristics that are relevant to the design of tools, machines, systems, tasks, jobs, and environments for safe, comfortable and effective human use.
Ergonomics also is a discipline or science of fitting workplace conditions and job demands to the capabilities of the worker. Many consider ergonomics a multi disciplinary field of applied science where knowledge about human capabilities, skills, limitations, and needs is taken into account when examining the interactions among people, technology, and the work environment (Westgaard and Winkel 1997;Cohen et al. 1997)
