The use of virtual reality technology in teaching environmental engineering

The Open University (OU) provides a Diploma in Pollution control as part of its undergraduate degree programme. The courses that make up the Diploma are presented in distance learning format using the OU's supported open learning system that has been developed over several decades. Teaching environmental engineering by distance learning presents several challenges in terms of ensuring that students gain an appreciation of the technology in action and receive the motivation and support more-readily available to students taught in a campus setting. The OU has developed a multi-media resources DVD to help meet these challenges for students undertaking an environmental impact assessment project. The DVD contains virtual reality views of the proposed site, maps of the region, supporting technical data, interviews with experts and advice from a virtual tutor. A survey of students using the DVD found that the overwhelming majority found the DVD to be 'very useful' or 'useful'. Understandably, the material that is essential for completing the project received the highest rating, but the background material was still considered to be useful by most students. Similar resources could benefit all students in many areas of engineering and technology

Discrete event simulation and virtual reality use in industry: new opportunities and future trends

This paper reviews the area of combined discrete event simulation (DES) and virtual reality (VR) use within industry. While establishing a state of the art for progress in this area, this paper makes the case for VR DES as the vehicle of choice for complex data analysis through interactive simulation models, highlighting both its advantages and current limitations. This paper reviews active research topics such as VR and DES real-time integration, communication protocols, system design considerations, model validation, and applications of VR and DES. While summarizing future research directions for this technology combination, the case is made for smart factory adoption of VR DES as a new platform for scenario testing and decision making. It is put that in order for VR DES to fully meet the visualization requirements of both Industry 4.0 and Industrial Internet visions of digital manufacturing, further research is required in the areas of lower latency image processing, DES delivery as a service, gesture recognition for VR DES interaction, and linkage of DES to real-time data streams and Big Data sets
