ABSTRACT:The globalization trend has affected the tertiary education sector, resulting in an increased flow of both students and academics across borders. Economic pressures on universities and the emergence of new technologies have spurred the creation of new systems in engineering education. The recent advances in computer graphics have exposed great potential in education at all levels. The Virtual Reality (VR) is a promising technology which aims to assist the students in the visualization of concepts and to provide immediate graphical feedback during the learning process. This article presents a modular interactive teaching package, called Virtual Learning System (VLS), which can be used by people with little prior computer experience. VLS provides a comprehensive and conductive yet dynamic and interactive environment that can be incorporated into various courses in the field of Mechanical and Manufacturing Engineering. The evaluation of the learning process with the developed system has been done through laboratory reports, lab quizzes and questionnaires implemented with a tutorial monitoring application.
The Virtual Reality (VR) is a computer system, which can save time, cut costs and help to improve the learning process in engineering laboratory education by interactive 3D simulation environments. This paper gives an overview on the VR applications in undergraduate engineering laboratory education and presents a VR system tool ‘Virtual CIM Laboratory’ (VCIMLAB), developed for laboratory training on Computer Integrated Manufacturing (CIM) systems. The proposed VR system is a cost-effective and safe approach of teaching the operations of automated manufacturing systems, which deal primarily with the expensive and complex high technology industrial automation equipments. The VCIMLAB allows students to self-experience on these systems without the need to work on actual equipments in the laboratory.
The design and development of holonic manufacturing systems requires careful, and sometimes risky, decision making to ensure that they will successfully satisfy the demands of an ever-changing market. In this paper, the authors propose a methodology for a holonic manufacturing systems requirement analysis that is based on a virtual reality approach and aimed at assisting designers of such systems along the entire systems design and development process. Exploiting virtual reality helps the user collect valid information quickly and in a correct form by putting the user and the information support elements in direct relation with the operation of the system in a more realistic environment. A prototype software system tool is designed to realise the features outlined in each phase of the methodology. A virtual manufacturing environment for matching the physical and the information model domains is utilised to delineate the information system requirements of holonic manufacturing systems implementation. A set of rules and a knowledge base is appended to the virtual environment to remove any inconsistency that could arise between the material and the information flows during the requirement analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
