Methodology for the Construction of a Virtual Environment for the Simulation of Critical Processes

There is a growing trend in education and training towards the use of online and distance learning courses. This delivery format provides flexibility and accessibility; it is also viewed as a way to provide education in a more effective way to a broader community. Online courses are comfortable, they are built under the missive of “anyone, anywhere, anytime”. Everyone can participate from home or workplace. Online courses can be developed in a variety of ways, for example, using a LMS (Learning Management System), a LCM (Learning Content System), or a Web 2.0 tool (or some mixture). These options, however, show limitations in terms of communication and interaction levels that can be achieved between students. Most learning systems are asynchronous and don't allow an effective real-time interaction, collaboration and cooperation. Whilst they typically have synchronous chats and whiteboards, these capabilities are often sterile and don’t stimulate the appropriate interactions that enhance learning. A rich interaction does not necessarily involve just verbal exchange since there is an huge learning value to be gained from interacting with the learning content in a more visual and practical way. For instance, imagine the learning benefits from collaborating on a 3D construction jointly and in real-time? Imagine watching the impact of soil erosion, or building and walking inside an heart model or a car engine? All this is possible in a 3D immersive virtual world. Students can engage at a distance building content in real-time, collaboratively and interactively. On the net there can be found an array of virtual worlds, however we have chosen Second Life® (SL®) to show how teaching and learning can be enhanced through the use of this platform. Second Life® is immersive, enabling users to interact, communicate and collaborate as if in the real world. SL® is a model of the real world, it shows an accurate physics simulation and it includes a meteorological and gravitational system; as such, anything can be modelled and simulated. Each user in the environment is represented by an avatar with all the features of a human being and avatars can manipulate the environment. Scientific experiments can be held in a very safe and controlled environment, and can be directly conducted by the scientist in charge. Scientific fields such as architecture, history, medicine, biology, sociology, programming, languages learning among many others can all be tested and researched through this virtual world.info:eu-repo/semantics/publishedVersio

Use of virtual simulator for agent training in radiation protection actions in major events

With the proximity of the events of the Olympic Games, Brazil can become a great place of visibility for running dirty bombs or any other radiation mode proliferation by terrorists. Aware of these problems, the government and the organizations created managements of emergencies to ensure that these events elapse in an orderly and safe manner. The management of emergency situations at an event is a complex problem, which involves dynamic, unforeseen and unintended situations, emphasizing the potential complexity of the contexts in which organizations operate and, as a consequence, the people involved in the execution of multiple tasks from activities that require intense cognitive effort, are often challenged to adapt dynamically to maintain the productivity of the organization at satisfactory levels of performance usually impedes these people reflect on the results of their actions and learn from them. Therefore, it is extremely important to create tools that address the methods and techniques of Cognitive Task Analysis (CTA) to assist in the previous training of the security agents, for example, detection and approaches of people who carry radioactive elements. One of the possible ways to accomplish this training is through the use of virtual reality. Virtual environments bring some advantages like reducing costs and risks. The aim of this paper is to present a virtual simulator to evaluate the use in training agents in major events. As a case study, the Maracanã and the agents of the National Nuclear Energy Commission (CNEN) was chosen

Intensive Driving Lesson System for Driving School

The focus of this project is to develop an Intensive Driving Lesson System for driving school that emphasize on aiding learning through 3D demonstration and interaction. The objectives of this project are to develop an intensive driving lesson system as a supplement to current driving lesson and JPJ's outline test, to incorporate the VR concept and giving information such as visualization in presenting the overviewof road driving scenarios to the students in the systemand to conduct a survey to evaluate system acceptance by the user. In order to achieve these objectives, the design method adopted to develop the system is based on Kulwinder Kaur's (1998). There are five (5) stages conducted in designing method; requirement analysis, task & domain analysis, design of VE, design of user support and navigation analysis and evaluation. The preliminary findings from the evaluation of the system showed that the completed system is able to compliment to the current driving lesson. Future recommendations and enhancements on the Intensive Driving Lesson system suggested that the use of 3D demonstration is refined further and implementation is applied with more details. The idea can be broaden by enhancing user navigation and interaction towards this features

AUTONOMOUS SYSTEMS & SAFETY ISSUES: THE ROADMAP TO ENABLE NEW ADVANCES IN INDUSTRIAL APPLICATIONS
