The term ergonomics is derived from a Greek word and concerns the study of the biological and technological data that allow the adaptation between man and machines or objects.
The translation of the Greek concept is associated with the standards that regulate and govern human action. However, ergonomics analyses the interaction between human beings and other elements within the system to promote human well-being and the performance of the system.
Ergonomics is that people and technology work in harmony and in unison. To do this, it focuses on the design of posts work, tools and utensils which, thanks to their characteristics, manage to meet human needs and address their limitations. Therefore, this discipline allows to avoid or at least reduce damage and human diseases due to the use of technology and artificial environments.
An ergonomic object is a convenient object at the user / user, effective and offering a good level of productivity. For example: it is has not bad person who spend hours and hours, every day, sitting in the office before a screen of computer for professional reasons. Ergonomics is to idealize and manufacture chairs (or seats) specific for this kind of work adapting some elements (such as the keyboard) with the comfort of the user in mind. In the absence of ergonomic techniques applied to such objects, the person may suffer from his back and having problems of joints, not to mention just one example.
Ergonomics involves concepts of engineering, Physiology, Biomechanics and psychology, among other sciences, to achieve its goals of efficiency and convenience.
