ZusammenfassungMedizinische Ersthelfer adäquat und realitätsnahe zu trainieren, ist eine Herausforderung. Realistische Umgebungen, die zu Übungszwecken gesperrt werden können, sind rar gesät und werden oftmals aufgrund von Budget und zeitlichen Einschränkungen selten genutzt. Das Zentrum am Berg (ZaB) der Montanuniversität Leoben, Österreich, hat hierzu bereits 2019 Lösungsansätze entwickelt, die das Training von Blaulichtorganisationen auch in unter Tage Situationen ermöglichen. Die Errichtung von Testzentren wie dem ZaB-Projekt folgt dem Vorschlag der EU-Kommission, die Sicherheit von Straßen- und Eisenbahntunneln zu erhöhen, und ist eine Reaktion auf die mehreren Tausend Tunnelkilometer in der EU, die in Betrieb oder im Bau sind.Mit der Teilnahme des ZaB am Forschungsprojekt MED1stMR wird ein weiterer Schritt in die Verbesserung solcher medizinischen Einsatztrainings unternommen. Nun soll nicht mehr nur im realen Umfeld trainiert werden können, sondern die Erfahrung aus dem Tunnel und seine Besonderheiten für Ersthelfer wandert in die erweiterte virtuelle Umgebung und es soll ein Trainingslösung entstehen, die Virtual Reality (VR) mit haptischen Objekten wie Simulationspuppen und der Messung von Stressdaten der Ersthelfer zu einer Mixed Reality (MR) Lösung vereint, um eine auf künstlicher Intelligenz basierte Szenario Steuerung zu implementieren, um letztlich die Leistung der medizinischen Ersthelfer unter Wahrung ihrer Resilienz zu steigern. MED1stMR Train – [Skills.Resilience.Performance] – Save Lives ist hierzu das Motto des EU geförderten Forschungs-Projektes.

This paper looks to expand on the INEC 2016 paper ‘The future role of virtual reality within warship support solutions for the Queen Elizabeth Class aircraft carriers’ presented by Ross Basketter, Craig Birchmore and Abbi Fisher from BAE Systems in May 2016 and the EAAW VII paper ‘Testing the boundaries of virtual reality within ship support’ presented by John Newell from BAE Systems and Simon Luck from BMT DSL in June 2017. BAE Systems and BMT have developed a 3D walkthrough training system that supports the teams working closely with the QEC Aircraft Carriers in Portsmouth and this work was presented at EAAW VII. Since then this work has been extended to demonstrate the art of the possible on Type 26. This latter piece of work is designed to explore the role of 3D immersive environments in the development and fielding of support and training solutions, across the range of support disciplines. The combined team are looking at how this digital thread leads from design of platforms, both surface and subsurface, through build into in-service support and training. This rich data and ways in which it could be used in the whole lifecycle of the ship, from design and development (used for spatial acceptance, HazID, etc) all the way through to operational support and maintenance (in conjunction with big data coming off from the ship coupled with digital tech docs for maintenance procedures) using constantly developing technologies such as 3D, Virtual Reality, Augmented Reality and Mixed Reality, will be proposed.  The drive towards gamification in the training environment to keep younger recruits interested and shortening course lengths will be explored. The paper develops the options and looks to how this technology can be used and where the value proposition lies.

Virtual reality (VR) is the term used to describe representation and perception in a computer-generated, virtual environment. The term was coined by author Damien Broderick in his 1982 novel “The Judas Mandala". The term "Mixed Reality" describes the mixing of virtual reality with pure reality. The term "hyper-reality" is also used. Immersion plays a major role here. Immersion describes the embedding of the user in the virtual world. A virtual world is considered plausible if the interaction is logical in itself. This interactivity creates the illusion that what seems to be happening is actually happening. A common problem with VR is "motion sickness." To create a sense of immersion, special output devices are needed to display virtual worlds. Here, "head-mounted displays", CAVE and shutter glasses are mainly used. Input devices are needed for interaction: 3D mouse, data glove, flystick as well as the omnidirectional treadmill, with which walking in virtual space is controlled by real walking movements, play a role here.

Recent advances in technology have made virtual environments, virtual reality, augmented reality, and simulations more affordable and accessible to researchers, companies, and the general public, which has led to many novel use cases and applications. A key objective of human factors research and practice is determining how these technology-rich applications can be designed and applied to improve human performance across a variety of contexts. This session will demonstrate some of the distinct and diverse uses of virtual environments and mixed reality environments in an alternative format. The session will begin with each demonstrator providing a brief overview of their virtual environment (VE) and a description of how it has been used to address a particular problem or research need. Following the description portion of the session, each VE will be set-up at a demonstration station in the room, and session attendees will be encouraged to directly interact with the virtual environment and ask demonstrators questions about their research and inquire about the effectiveness of using VE for research, training, and evaluation purposes. The overall objective of this alternative session is to increase the awareness of how human factors professionals use VE technologies and increase the awareness of the capabilities and limitations of VE in supporting the work of HF professionals.

Current teaching practice in undergraduate higher education anatomy and physiology courses incorporates the use of various instructional methodologies to reinforce the anatomical relationships between structures.1,2 These methods can include basic hands-on physical models, human and animal dissection labs, and interactive technology. Technological advances continue to drive the production of innovative anatomy and physiology electronic tools, including:virtual dissection in 3-D (e.g., Virtual Dissection Boards from Anatomage, 3D4Medical, and Anatomy.TV),augmented reality (AR) (e.g., Human Anatomy Atlas),mixed reality (e.g., Microsoft HoloLens Case Western Reserve Medical School and Cleveland Clinic digital anatomy app), and3-D virtual reality (VR) (e.g., 3D Organon VR Anatomy and YOU by Sharecare apps).

Even experienced mountain climbers underestimate key dangers and make poor decisions in stressful, high-risk situations when climbing, leading to injury and death. My own experience indicates that effective education can play a key role in managing these risks and improving experienced climber’s decision making. Current educational approaches for climbers, however, are generally limited to textbooks and ‘on the mountain’ learning. It is vital, therefore, that new approaches and methods are developed to improve learning.    My own experience and emergent case studies indicate that AR (Augmented), VR (Virtual Reality) and MR (Mixed Reality), have affordances (possibilities offered by the technology) to underpin new forms of learning and therefore have the potential to enhance education for high-risk environments. Emergent use of MR immersive technologies includes classroom learning, firefighting and military training. An initial review of literature has indicated though that there are very limited examples of rigorous research on the design and application of MR technologies in authentic education, especially for extreme situations such as mountaineering i.e., no one has rigorously designed for these technologies for learning in extreme environments, evaluated learning outcomes and theorised about how learning can be enhanced.    In response to this gap/opportunity, this research explores the potential of MR technologies to effectively enhance learning for authentic, high-risk situations. The research will use a Design-based research methodology (DBR) to develop design principles informed by key learning theories as they offer recognised and critical approaches for a new way of learning in an extreme environment.  Underpinned by a Constructivist paradigm, initial theoretical frameworks identified include Authentic Learning and Heutagogy (student-determined learning).Herrington and co-authors (2009) recommended 11 design principles for the incorporation of mobile learning into a higher education learning environment, and Blaschke and Hase (2015)’s 10 principles of designing learning for heutagogy. Other theories and frameworks include Constructivist Learning and the ZPD (the Zone of Proximal Development), design for mobile MR learning and user-centred design. Activity Theory will also be utilised in the data analysis.   Initial design principles will be developed by the DBR methodology. These design principles will be tested through the implementation and evaluation of an MR ‘prototype’ app design solution.’ The prototype solution will be iteratively redesigned using further evaluation and feedback from sample cohorts of end-users. Data will be collected from key participant interviews, researcher observation/reflections and biometric feedback. Methodological triangulation (multimodal data approach) will be used to evaluate learning outcomes. The iterative development will lead to transferable design principles and further theorising that can be transferred to other learning situations involving preparation and decision-making as well as knowledge in high-risk contexts.    Reference   Amiel, T., & Reeves, T.

Over the years educators have adopted a variety of technologies in a bid to improve student engagement, interest and understanding of abstract topics taught in the classroom. There has been an increasing interest in immersive technology such as Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). The ability of VR to bring ideas to life in three dimensional spaces in a way that is easy for students to understand the subject matter makes it one of the important tools available today for education. A key feature of VR is the ability to provide multi-sensory visuals and virtual interaction to students wearing a Head Mounted Display thus providing students better learning experience and connection to the subject matter. Virtual Reality has been used for training purposes in the health sector, military, workplace training, gamification and exploration of sites and countless others. With the potential benefits of virtual technology in visualizing abstract concepts in a realistic virtual world, this paper presents a plan to study the use of situated cognition theory as a learning framework to develop an immersive VR application that would be used to train and prepare students studying Telecommunications Engineering for the workplace. This paper presents a review of literature in the area of Virtual Reality in education, offers insight into the motivation behind this research and the planned methodology in carrying out the research.

BACKGROUND Dental simulator is used in preclinical skills training and virtual reality is the main technology of it. With the development of XR technology, mixed reality appeared and it has significant advantage over virtual reality. OBJECTIVE This study intended to research and develop a mixed reality (MR) and haptic-based dental simulator for tooth preparation and preliminarily evaluate its face validity. METHODS A prototype of MR dental simulator for tooth preparation was innovatively developed by integrating the head-mounted display (HMD), special force feedback handles, foot pedal, computer hardware, and software program. Thirty-four participants were recruited and were divided into Novice group (N=17) and Skilled group (N=17) based on their clinical experience. All participants prepared a maxillary right central incisor for all ceramic crown in the dental simulator, and completed a questionnaire after the preparation to investigate their experience and evaluation toward the dental simulator in aspects of the hardware and software. RESULTS A prototype of MR dental simulator for tooth preparation (Unidental MR Simulator) was newly developed. 73.53% of the participants were satisfied with the overall experience in using Unidental MR Simulator. Over 90% of the participants agreed with that Unidental MR Simulator can stimulate their interest in learning and over 80 % of them were willing to use dental simulator Unidental MR Simulator for skills training in the future. The differences in the experience of the HMD, simulation of the dental instruments, realism of the force feedback of teeth, simulation of the tooth preparation process, overall experience of the simulator and attitudes toward the simulator between Novice group and Skilled group were not statistically significant (P>0.05). Novice group were more satisfied with the ease of use of the simulator. (P<0.05). The resolution of the HMD and the simulation of the preparation process had significant positive correlations with the overall using experience of the simulator (P<0.05). CONCLUSIONS The newly developed dental simulator for tooth preparation, Unidental MR simulator, has a good face validity. It can achieve a higher degree of similarity to the real clinical treatment environment by achieving position adjustment of patients, allowing users to have a better dental skill training experience.
