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

Open-source digital technologies for low-cost monitoring of historical constructions

This paper shows new possibilities of using novel, open-source, low-cost platforms for the structural health monitoring of heritage structures. The objective of the study is to present an assessment of increasingly available open-source digital modeling and fabrication technologies in order to identify the suitable counterparts of the typical components of a continuous static monitoring system for a historical construction. The results of the research include a simple case-study, which is presented with low-cost, open-source, calibrated components, as well as an assessment of different alternatives for deploying basic structural health monitoring arrangements. The results of the research show the great potential of these existing technologies that may help to promote a widespread and cost-efficient monitoring of the built cultural heritage. Such scenario may contribute to the onset of commonplace digital records of historical constructions in an open-source, versatile and reliable fashion.Peer ReviewedPostprint (author's final draft

VIRTUAL ACCESS TO HERITAGE THROUGH SCIENTIFIC DRAWING, SEMANTIC MODELS AND VR-EXPERIENCE OF THE STRONGHOLD OF ARQUATA DEL TRONTO AFTER THE EARTHQUAKE

Interactive representation has proven to be an effective tool in various disciplines related to Digital Cultural Heritage (DCH). This study proposes a research method that uses interactive representation to share complex scenarios like the Stronghold of Arquata del Tronto, facilitating novel forms of heritage dissemination. The scan-to-BIM process made it possible to digitise complex structural elements damaged by the 2016 earthquake. The investigation of the complexity paradigm improved the reliability of the semantic model that supports the preservation process. Interoperability and accessibility paradigms were explored to create a more comprehensive and accurate understanding of the built heritage. A web-VR platform was developed to enhance user interaction and simplify virtual environment exploration without using complex hardware (VR headset and controllers), making it possible to experience VR in the browser

Failure-enhanced evacuation training using a VR-based disaster simulator : A comparative experiment with simulated evacuees

Evacuation training is an important component of disaster education and survival. Evacuation training using a virtual reality (VR)-based disaster simulator that provides a highly immersive simulated evacuation experience (SEE) has attracted significant attention. To improve the training effect, we propose a failure-enhanced evacuation training model based on Kolb’s experiential learning theory. Our model aims to purposefully induce participants to succumb to conformity bias and fail to evacuate during the first SEE because inactive evacuees (i.e., people who are not evacuating speedily or not starting their evacuation) are simulated in a VR-based disaster simulator. The participants are expected to overcome failure in the second SEE via reflection and conceptualization. A preliminary comparative experiment focused on how simulated evacuees influence the SEE of participants in a VR-based disaster simulator. Results indicated that failure-enhanced evacuation training can successfully improve the training effect
