Virtual Reality as support for Learning in Electrical Engineering

Abstract

All Higher Education Institutions play a decisive role in adapting the new courses to the needs of society and the world of work. ICTs widen the possibilities of uses, at a relatively low cost; therefore, additional measures need to be taken in terms of methodologies to implement flexible learning processes, at their own special pace. The possibility of performing real life experiments is essential to consolidate concepts taught in theoretical classes of scientific and technical curricular units. Real labs are seldom available, posing restrictions to learning and experimentation. New internet-based technologies can be used to improve the access to these experiences using laboratories with simulated experiments. This paper aims at presenting the development of a prototype using tools to create virtual learning environments. It uses virtual experimentation to perform laboratory practices and as an alternative tool to meet the needs of access to a Measurement and Instrumentation laboratory. The basis of the project was the creation of a 3D laboratory where all the equipment and its components may be observed and manipulated and virtual experimentation was chosen to facilitate all laboratory practices. A creative tool or authoring tool was used for the development of the program called "VEMA" -Virtual Electric MAnual. The use of WireFusion 5.0 ® authoring tool and an educational license explain the low cost of construction of the virtual reality (VR) program. This project was developed to demonstrate how a VR desktop prototype may be applied to an engineering curricular unit and also to increase safety and resourcefulness in the use of electrical equipment. From the educational point of view, VEMA should not be seen as a substitute of traditional teaching methods, but only as a complementary resource that can meaningfully improve students' understanding and motivation. The main objective of VEMA was to develop a prototype of a VR simulator to demonstrate the potential benefits of combining virtual reality to improve learning and measurement of electrical circuits in a specific controlled environment.
