Item Acesso aberto (Open Access) Framework para criação de laboratórios virtuais: diminuindo a lacuna entre teoria e prática em engenharia elétrica(Universidade Federal do Pará, 2015-05-08) BARATA, Pebertli Nils Alho; RIBEIRO FILHO, Manoel; http://lattes.cnpq.br/9329438229733907Within 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.Item Acesso aberto (Open Access) Projeto e implementação de um sistema de autoria para animações, simulações e treinamentos em realidade virtual(Universidade Federal do Pará, 2010-09-03) BARATA, Pebertli Nils Alho; RIBEIRO FILHO, Manoel; http://lattes.cnpq.br/9329438229733907This dissertation presents the design, development and implementation of a software for the creation of animation, simulations and training processes and industrial technical instructions, also presents the architecture used for its implementation. The software presented allows the generation of animation, texts, sounds and interactions, providing tools for creating, display and supervision of simulation with use of Virtual Reality 3D. The dissertation also deals with the practical use of the software through a case study with simulations 3D in real industrial processes of a plant for generation of electric energy. This study also contributes to the areas of training and virtual reality and systems of authorship 3D to submit innovative concepts in the area of supervision automatic, also showing a possible structure of software components for use in the areas mentioned. May also be highlighted the review of similar technologies to the purpose of this study, aiming to the identification of influences, improvements and innovations in the areas of authorship 3D and training.
