    Virtual reality (VR) and augmented reality (AR) have long histories in the healthcare sector, offering the opportunity to develop a wide range of tools and applications aimed at improving the quality of care and efficiency of services for professionals and patients alike. The best-known examples of VR–AR applications in the healthcare domain include surgical planning and medical training by means of simulation technologies. Techniques used in surgical simulation have also been applied to cognitive and motor rehabilitation, pain management, and patient and professional education. Serious games are ones in which the main goal is not entertainment, but a crucial purpose, ranging from the acquisition of knowledge to interactive training.These games are attracting growing attention in healthcare because of their several benefits: motivation, interactivity, adaptation to user competence level, flexibility in time, repeatability, and continuous feedback. Recently, healthcare has also become one of the biggest adopters of mixed reality (MR), which merges real and virtual content to generate novel environments, where physical and digital objects not only coexist, but are also capable of interacting with each other in real time, encompassing both VR and AR applications.This Special Issue aims to gather and publish original scientific contributions exploring opportunities and addressing challenges in both the theoretical and applied aspects of VR–AR and MR applications in healthcare

    This thesis proposes a new virtual simulation environment designed as element of an interoperable federation of simulator to support the investigation of complex scenarios over the Extended Maritime Framework (EMF). Extended Maritime Framework is six spaces environment (Underwater, Water surface, Ground, Air, Space, and Cyberspace) where parties involved in Joint Naval Operations act. The amount of unmanned vehicles involved in the simulation arise the importance of the Communication modelling, thus the relevance of Cyberspace. The research is applied to complex cases (one applied to deep waters and one to coast and littoral protection) as examples to validate this approach; these cases involve different kind of traditional assets (e.g. satellites, helicopters, ships, submarines, underwater sensor infrastructure, etc.) interact dynamically and collaborate with new autonomous systems (i.e. AUV, Gliders, USV and UAV). The use of virtual simulation is devoted to support validation of new concepts and investigation of collaborative engineering solutions by providing a virtual representation of the current situation; this approach support the creation of dynamic interoperable immersive framework that could support training for Man in the Loop, education and tactical decision introducing the Man on the Loop concepts. The research and development of the Autonomous Underwater Vehicles requires continuous testing so a time effective approach can result a very useful tool. In this context the simulation can be useful to better understand the behaviour of Unmanned Vehicles and to avoid useless experimentations and their costs finding problems before doing them. This research project proposes the creation of a virtual environment with the aim to see and understand a Joint Naval Scenario. The study will be focusing especially on the integration of Autonomous Systems with traditional assets; the proposed simulation deals especially with collaborative operation involving different types of Autonomous Underwater Vehicles (AUV), Unmanned Surface Vehicles (USV) and UAV (Unmanned Aerial Vehicle). The author develops an interoperable virtual simulation devoted to present the overall situation for supervision considering also the sensor capabilities, communications and mission effectiveness that results dependent of the different asset interaction over a complex heterogeneous network. The aim of this research is to develop a flexible virtual simulation solution as crucial element of an HLA federation able to address the complexity of Extended Maritime Framework (EMF). Indeed this new generation of marine interoperable simulation is a strategic advantage for investigating the problems related to the operational use of autonomous systems and to finding new ways to use them respect to different scenarios. The research deal with the creation of two scenarios, one related to military operations and another one on coastal and littoral protection where the virtual simulation propose the overall situation and allows to navigate into the virtual world considering the complex physics affecting movement, perception, interaction and communication. By this approach, it becomes evident the capability to identify, by experimental analysis within the virtual world, the new solutions in terms of engineering and technological configuration of the different systems and vehicles as well as new operational models and tactics to address the specific mission environment. The case of study is a maritime scenario with a representation of heterogeneous network frameworks that involves multiple vehicles both naval and aerial including AUVs, USVs, gliders, helicopter, ships, submarines, satellite, buoys and sensors. For the sake of clarity aerial communications will be represented divided from underwater ones. A connection point for the latter will be set on the keel line of surface vessels representing communication happening via acoustic modem. To represent limits in underwater communications, underwater signals have been considerably slowed down in order to have a more realistic comparison with aerial ones. A maximum communication distance is set, beyond which no communication can take place. To ensure interoperability the HLA Standard (IEEE 1516 evolved) is adopted to federate other simulators so to allow its extensibility for other case studies. Two different scenarios are modelled in 3D visualization: Open Water and Port Protection. The first one aims to simulate interactions between traditional assets in Extended Maritime Framework (EMF) such as satellite, navy ships, submarines, NATO Research Vessels (NRVs), helicopters, with new generation unmanned assets as AUV, Gliders, UAV, USV and the mutual advantage the subjects involved in the scenario can have; in other word, the increase in persistence, interoperability and efficacy. The second scenario models the behaviour of unmanned assets, an AUV and an USV, patrolling a harbour to find possible threats. This aims to develop an algorithm to lead patrolling path toward an optimum, guaranteeing a high probability of success in the safest way reducing human involvement in the scenario. End users of the simulation face a graphical 3D representation of the scenario where assets would be represented. He can moves in the scenario through a Free Camera in Graphic User Interface (GUI) configured to entitle users to move around the scene and observe the 3D sea scenario. In this way, players are able to move freely in the synthetic environment in order to choose the best perspective of the scene. The work is intended to provide a valid tool to evaluate the defencelessness of on-shore and offshore critical infrastructures that could includes the use of new technologies to take care of security best and preserve themselves against disasters both on economical and environmental ones

    The Effects of Primary and Secondary Task Workloads on Cybersickness in Immersive Virtual Active Exploration Experiences

    Get PDF
    Virtual reality (VR) technology promises to transform humanity. The technology enables users to explore and interact with computer-generated environments that can be simulated to approximate or deviate from reality. This creates an endless number of ways to propitiously apply the technology in our lives. It follows that large technological conglomerates are pushing for the widespread adoption of VR, financing the creation of the Metaverse - a hypothetical representation of the next iteration of the internet. Even with VR technology\u27s continuous growth, its widespread adoption remains long overdue. This can largely be attributed to an affliction called cybersickness, an analog to motion sickness, which often manifests in users as an undesirable side-effect of VR experiences, inhibiting its sustained usage. This makes it highly important to study factors related to the malady. The tasks performed in a simulated environment provide context, purpose, and meaning to the experience. Active exploration experiences afford users control over their motion, primarily allowing them to navigate through an environment. While navigating, users may also have to engage in secondary tasks that can be distracting. These navigation and distraction tasks differ in terms of the source and magnitude of attentional demands involved, potentially influencing how cyber-sickening a simulation can be. Given the sparse literature in this area, this dissertation sets out to investigate how the interplay between these factors impacts the onset and severity of sickness, thereby contributing to the knowledge base on how the attentional demands associated with the tasks performed during navigation affect cybersickness in virtual reality

    Understanding VR/AR in marketing & sales for B2B: an explorative study

    Get PDF
    Abstract. The research explored the impact of immersive reality technologies, particularly VR and AR, in marketing and sales for the B2B sector. Study interests were fuelled by both an industrial hype and vehement investments on these technologies, especially in the last five years. However, the potential of these technologies is still unexplored and widely misunderstood by businesses as the innovations are slowly taking off. Additionally, existing literature showed a need to clearly define various simulated realities in the continuum, including VR and AR, as well as a general misunderstanding of the potential of immersive reality technologies, and a shortage of studies covering holistically different VR/AR applications in marketing, especially for the B2B sector. Therefore, this research aims to bridge the gap between managerial and academic’ understanding by providing a holistic framework explaining the impact of immersive reality technologies in B2B marketing and sales and provide a clear distinction between VR and AR in the Virtuality-reality continuum. This research also aims to assist marketers and managers in embracing these technologies to better meet the needs of future generations. The study adopted a qualitative exploratory approach allowing researchers to gain an in-depth understanding of the topic from an industrial perspective. The study used an abductive thematic analysis approach to analyse empirical results and ten semi-structured interviews with eleven VR/AR providers for primary data collection. Results were structured based on four main themes, namely: VR and AR definitions, customer technology adoption factors, VR/AR impact and applications on B2B marketing, and last, VR/AR impact on sales performance outcomes. This study contributes to the existing literature by proposing a tentative definition for each terminology “VR” and “AR” separately that merges academic perspectives and industry insights. Overall, empirical study suggests that immersive reality technologies can affect both marketing activities and sales performance outcomes for the B2B sector. However, successfully embracing these technologies calls for collaboration to overcome financial, technical and social barriers while also enhancing aspects like the user experience to step out of the still immature VR/AR market. VR and AR together have an impact on marketing for B2B by enhancing customization, non-verbal communication, learning and experiential marketing while also creating memorable experiences that stick in the minds of the consumer. Concerning the customer’s purchasing journey, this study extends existing literature to cover all customer purchasing stages, including the pre-purchase, purchase and post-purchase. Results emphasize the pre-purchase phase as the most impacted by immersive reality technologies, followed by post-purchase and purchase stages, respectively. Finally, this study suggests that the use of VR/AR as sales support tools can yield positive efficiency returns through higher task performance and a reduction in sales-related costs, and positive effectiveness returns through greater customer and social engagement, stronger collaborative business relationships and the enhancement of proactive (sales planning) and reactive (adaptive selling) behaviours in the sales process
