ABSTRACT

One of the major challenges that companies increasingly face is related to the health and well-being of workers especially those directly related to the operation and maintenance of electrical systems. These technicians have to perform tasks that mobilize knowledge and reasoning for which they received training, which from the point of view of the current rules are adequate. However, there are some factors that need to be improved because there are still accidents and incidents caused mainly caused by fatigue. In these systems, a confusing Human Computer Interface (HCI) with an operator can result in misinterpretation and induce errors during decision making. Therefore these systems require, among other characteristics of quality, safety, adaptability to different users and levels of experience, and training facility associated with their learning and use (Lima, 2006; Vieira, et al., 2009.).
