The field of ergonomics has been developed over the last 70 years. From various fields have been the ergonomic intervention methods to contribute to the improvement of jobs, products and interactional interfaces. Thus, the study of ergonomics is an ally, especially for engineering courses, industrial design and Occupational Health. Engineering for the contribution has been principlamente, regarding: biomechanical aspects and assumed postures. Industrial design the emphasis is in the field of cognition and interfaces, usability and ergonomics of the product. For Occupational Health the focus is related to postural and study the effect of activity in the musculoskeletal system and psycho-social factors. We can say that all professional fields that interact with the ergonomics are the promotion of human well-being and productivity as the main focus of their studies.

 

For the student, in general, the ergonomics behind the challenge of expanding the perception of planned and effective action of those involved in the different tasks. The transposition of the effects they will have on the perpetrators must be provided in a clear and factual way as an activity in which the planning only provides unilaterally the task, will surely bring unrest to the set.

 

The need to manage a greater number of variables that meet the project looks like someone who is thirsty and tries to drink tap into a large diameter, ie the odds of drinking become impaired even with the large supply of water. This analogy can be made to the planning of a product as well as a job. Each activity has specific characteristics, but there is one condition, which a priori should be answered - the welfare of those involved in the tasks.

 

The evolution of man has been put to the test there is the view the numerous repeated misconceptions taken over time, such as inappropriate use and management of resources, knowledge and people. Surely the reader can argue about the good examples betting on practices that impact the environment x x man system so the machine to allow the reorganization of most naturally system. In this way, we can support in the consolidated examples and difundirmos for environments that still suffer, systematically, for actions that do not meet the highest priority that is man.

The definitions of Brazilian Ergonomics Association (ABERGO) (2000), Conservatoire National des Arts et Métiers (CNAM) (2000) and the International Ergonomic Association (IEA) (2000), Ergonomics and Human Factors is: "[...] A scientific discipline related to the understanding of interactions among humans and other elements or systems, and the application of theories, principles, data and methods to design in order to optimize human well-being and overall system performance".
