Perceived Impact of Virtual Scenario-Based Branching Simulations Among Radiology Program Students

The influx of medical technology and medical knowledge creates challenges for healthcare providers in maintaining up to date knowledge and skills for their practice. Healthcare educators are further challenged in that the goal is to encourage learners to become competent healthcare providers who are knowledgeable and skilled, self-directed, and who will think critically and ethically when faced with challenging situations. Advancing imaging technologies and new complex procedures in radiology increase the risk of harm for patients and providers as advanced imaging is often learned outside of a primary degree in radiology with real patients through on the job training. Online education has been a way for the profession to extend needed education to working technologists, however, radiology education programs need ways to improve the level of learning in online advanced modality courses. This study explored an innovative teaching method to identify which will aid in current and future demands in radiology. Based on a review of the literature on scenarios, simulations, and virtual learning environments, virtual scenario-based branching simulations were designed, built, and implemented for this study. The virtual 2D role-playing scenario in which the student played the role of a new technologist in an advanced imaging suite provided students an opportunity for experiential learning online. The branching design, in which the patient and storyline evolves with the learner’s decisions required the learner to think critically and draw upon previous knowledge to make decisions about what should be done. This changed the direction of the stories and the outcomes of the virtual patients and personnel. The simulations were designed to enhance the level of learning in magnetic resonance imaging and in computed tomography online courses. They were tested with 57 advanced modality students to determine the impact the virtual scenario-based branching design had on student satisfaction with the experience and also their perceived confidence in making critical decisions in real practice. This mixed methods case study provided an analysis of both quantitative and rich qualitative data in a concurrent design. The participant voice provided insight into how this experience positively impacted this particular group of students and it also provided support for further development of virtual scenario-based simulations in a healthcare context. The implications for these simulations are wide-ranging. From the results of this study, this innovation appeared to provide a level of learning that emulated a clinical rotation. As the education of healthcare professionals requires deliberate practice of technical and cognitive skills, these simulations do not aim to replace hands-on learning with actual patients, but they do aim to improve student satisfaction in learning and to enhance the perceived confidence in transferring their knowledge to enhance actual practice, thereby minimizing risk to patients

Enabling the Development and Implementation of Digital Twins : Proceedings of the 20th International Conference on Construction Applications of Virtual Reality

Welcome to the 20th International Conference on Construction Applications of Virtual Reality (CONVR 2020). This year we are meeting on-line due to the current Coronavirus pandemic. The overarching theme for CONVR2020 is "Enabling the development and implementation of Digital Twins". CONVR is one of the world-leading conferences in the areas of virtual reality, augmented reality and building information modelling. Each year, more than 100 participants from all around the globe meet to discuss and exchange the latest developments and applications of virtual technologies in the architectural, engineering, construction and operation industry (AECO). The conference is also known for having a unique blend of participants from both academia and industry. This year, with all the difficulties of replicating a real face to face meetings, we are carefully planning the conference to ensure that all participants have a perfect experience. We have a group of leading keynote speakers from industry and academia who are covering up to date hot topics and are enthusiastic and keen to share their knowledge with you. CONVR participants are very loyal to the conference and have attended most of the editions over the last eighteen editions. This year we are welcoming numerous first timers and we aim to help them make the most of the conference by introducing them to other participants

Virtual Guidance using Mixed Reality in Historical Places and Museums

Mixed Reality (MR) is one of the most disruptive technologies that shows potential in many application domains, particularly in the tourism and cultural heritage sector. MR using the latest headsets with the highest capabilities introduces a new visual platform that can change people’s visual experience. This thesis introduces a HoloLens-based mixed reality guidance system for museums and historical places. This new guidance form considers the inclusiveness of the necessary and optimised functionalities, visual and audio guiding abilities, essential roles of a guide, and the related social interactions in the real-time. A mixed reality guide, dubbed ‘MuseumEye’ was designed and developed for the Egyptian Museum in Cairo, to overcome challenges currently facing the museum, e.g. lack of guiding methods, limited information signposted on the exhibits, lack of visitor engagement resulting in less time spent in the museum compared to other museums with similar capacity and significance. These problems motivated the researcher to conduct an exploratory study to investigate the museum environment and guiding methods by interviewing 10 participants and observing 20 visitors. ‘MuseumEye’ was built based on a literature review of immersive systems in museums and the findings of an exploratory study that reveals visitor behaviours and the nature of guidance in the museum. This project increased levels of engagement and the length of time visitors spend in museums, the Egyptian Museum in Cairo in particular, using the mixed reality technology that provides visitors with additional visual, audio information and computer-generated images at various levels of details and via different media. This research introduces the guidelines of designing immersive reality guide applications using the techniques of spatial mapping, designing the multimedia and UI, and designing interactions for exploratory purposes. The main contributions of this study include various theoretical contributions: 1) creating a new form of guidance that enhances the museum experience through developing a mixed reality system; 2) a theoretical framework that assesses mixed reality guidance systems in terms of perceived usefulness, ease of use, enjoyment, interactivity, the roles of a guide and the likelihood of future use; 3) the Ambient Information Visualisation Concept for increasing visitor engagement through better presenting information and enhancing communication and interaction between visitors and exhibits; and a practical contribution in creating a mixed reality guidance system that reshapes the museum space, enhances visitors’ experience and significantly increases the length of time they spend in the museum. The evaluation comprised of quantitative surveys (171 participants and 9 experts) and qualitative observation (51 participants) using MuseumEye in their tours. The results showed positive responses for all measured aspects and compares these to similar studies. The observation results showed that visitors who use MuseumEye spent four times the duration visitors spent without guides or with human guides in front of exhibited items. The quantitative results showed significant correlations between the measured constructs (perceived usefulness, ease of use, enjoyment, multimedia and UI, interactivity) and the likelihood of future use when the roles of guide mediate the relations. Moreover, the ‘perceived guidance’ is the most influential construct on the likelihood of future use of MuseumEye. The results also revealed a high likelihood of future use, which ensures the sustainability of adopting mixed reality technology in museums. This thesis shows the potential of mixed reality guides in the museum sector that reshape the museum space and offers endless possibilities for museums and heritage sites
