Within the Electrical Engineering field of study, the understanding of some equipment can be frustrating and demotivating due to lack of a clear vision of how these devices work and operate in a real environment. Both students and professionals find it difficult to meet or train with this equipment, by factors such as safety, cost of maintaining a laboratory or impediments to training in real installations. Various forms of teaching and learning have been used to enhance this practical aspect of learning in Electrical Engineering. Among these forms, the use of virtual reality has had good results by providing a safe, controlled environment and inexpensive compared to an actual laboratory. However, there are still gaps that can be addressed in these experiments, for example, serve both students and professionals, ease of creation of laboratories and play real situations of equipment, nearing the theory of the practice. Thus, this thesis proposes a conceptual framework for creating virtual labs to fill these gaps. A systematic review was conducted to collect characteristics, opportunities and challenges of this issue. The framework presents methods, techniques and best practices for defining, creating, implementing and measuring virtual reality experiments applied to Electrical Engineering. Experiments are presented which were performed to validate the framework. An experiment demonstrates the teaching of operating electrical transformers in substations for undergraduate students of Electrical Engineering. Another experiment trains professionals to operation and maintenance of a hydro generator turbine at a hydroelectric plant. The results show that the framework enabled the best practical study to show actual scenarios and situations of the concepts presented and improved aspects of teaching and learning as notes, motivation and retention of knowledge for both students and professionals as to the teacher.

This simulator is formed by the junction of Virtual Reality techniques with propagation models, developed through the studies of radio enlace, describing the loss that the transmitted signal suffers along the way in the environment. The Simulator has two modules. The first allows the creation of virtual environment with the placement, on a ground, buildings, trees, cars, antennas and other primitives that allow the construction of a customizable three-dimensional environment. The second module allows the configuration of the parameters related to antenna signal propagation as power, frequency, gain, etc., and also selects the propagation model for the simulation execution. Within this second module, there is a submodule responsible for coverage area planning study composed by antennas, in other words, this submodule simulates the distance that each antenna in the scenario can reach and generates its coverage area. To demonstrate the Simulator efficiency was created two virtual environments for testing. A scenario representing an urban environment where employed a classic propagation model, Okumura-Hata to small and medium-sized cities, and a wooded three-dimensional environment using a specific model for propagation simulation of densely wooded regions, developed at the Federal University of Pará called Lyra- Castro-UFPA.

Now thanks to the exponential evolutionary process of the hardware equipments, mainly the related to storage of data, it is possible to store enormous amounts of data, of all possible types, in a centralized base and/or distributed. There are some a little years ago was known what to do with such amount of stored data, in the days you act is known already that the organization that best to dominate the coming information of the is half that more chance will have to be well happened. Based on the mentioned premises is necessary that the responsible for the take of decision use tools of information visualization to aid in the ruling process, doing with that the same if turns more reliable, fast, intuitive and accurate. The information visualization uses techniques of data presentation with the objective of turning them more perceptible and intuitive for the user, however when there is need to present great amounts of data, the visualization is prejudiced for several reasons. To resolve this visualization problem, the use of the Virtual Reality (VR) if it turns essential due to the possibility that this interface provides just as interaction and navigability, characteristics that turn the most productive and interesting visualization. However, usually the ruling of decision is not made by a single person, and the tools in his great majority are mono-users, harming the ruling decision, mainly if the people are distant some of the other ones. With a collaborative environment of data visualization, it is possible to discuss on the same vision of data decreasing the time and unnecessary misunderstandings to the ruling decision. This work has for aim project and implementation a tool of information visualization in an environment three-dimensional virtual collaborative to aid the user in the ruling decentralized decision.
