In this article, virtual reality (VR) and augmented reality (AR) are analysed from the standpoint of digital materialism, which states that any digital matter (including VR and AR) is an in-material construct. The authors describe VR and AR as special ontological models. It is emphasized that the basis for the creation and development of VR and AR is the sense of touch, which, in its turn, is a fusion of sensations, including optic ones. Moreover, the authors consider the hand to be the source of and a metaphor for VR and AR: it is the main organ of the human body responsible for touch and, therefore, determines haptics as a fundamental mode of comprehension of regular reality. Thus, the concept of entelechy introduced by Aristotle can serve as a key to understand how VR and AR are implemented and presented. If, according to Aristotle, the soul as a hand is the entelechy of a natural body, then a hand in a cyber glove, which makes staying in VR possible, is the entelechy of a body converged with the electronic and digital environment. In the case of AR, a hand does not necessarily require technogarments and turns out to be the entelechy of a non-technological body immersed, with its help, into the electronic and digital environment. As a result, VR and AR themselves become the entelechies, that is, tangible, or, in other words, haptically perceived forms and images of being. The authors conclude that both VR and AR depend on human experience and are ontologically irresponsible. Allowing a person to comprehend his/her own existence in the affordances bestowed upon him/her, VR and AR demonstrate how the human body reacts to the work of the brain immersed into the virtual and augmented worlds.

The best way to disseminate culture is, nowadays, the creation of scenarios with virtual and augmented reality that supply the visitors of museums with a powerful, interactive tool that allows to learn sometimes difficult concepts in an easy, entertaining way. 3D models derived from reality-based techniques are nowadays used to preserve, document and restore historical artefacts. These digital contents are also powerful instrument to interactively communicate their significance to non-specialist, making easier to understand concepts sometimes complicated or not clear. Virtual and Augmented Reality are surely a valid tool to interact with 3D models and a fundamental help in making culture more accessible to the wide public. These technologies can help the museum curators to adapt the cultural proposal and the information about the artefacts based on the different type of visitor’s categories. These technologies allow visitors to travel through space and time and have a great educative function permitting to explain in an easy and attractive way information and concepts that could prove to be complicated. The aim of this paper is to create a virtual scenario and an augmented reality app to recreate specific spaces in the Capitoline Museum in Rome as they were during Winckelmann’s time, placing specific statues in their original position in the 18th century.

Education & outreach is an important part of HEP experiments. With outreach & education, experiments can have an impact on the public, students and their teachers, as well as policymakers and the media. The tools and methods for visualization enable to represent the detectors’ facilities, explaining their purpose, functionalities, development histories, and participant institutes. In addition, they make it possible to visualize different physical events together with important parameters and plots for physics analyses. 3D visualization and advanced VR (Virtual Reality), AR (Augmented Reality) and MR (Mixed Reality) extensions are the keys for successful outreach & education. This paper describes requirements and methods for the creation of browser-based visualization applications for outreach & education. The visualization framework TRACER is considered as a case study.

The advent of all types of eXtended Reality (XR)—VR, AR, MR—raises serious questions, both technological and pedagogical. The setup of campus services around XR is only the prelude to the more complex and expensive project of creating learning content using XR. In 2018, the authors started a limited proof-of-concept augmented reality (AR) project for a library tour. Building on their previous research and experience creating a virtual reality (VR) library tour, they sought a scalable introduction of XR services and content for the campus community. The AR library tour aimed to start us toward a matrix for similar services for the entire campus. They also explored the attitudes of students, faculty, and staff toward this new technology and its incorporation in education, as well as its potential and limitations toward the creation of a “smart” library.

This paper shows the use of web resources for the creation of Virtual Reality (VR) and Augmented Reality (AR) environments to teaching of topographic surface concepts. The mockups of the topographic surfaces were built with Sketchup software, include graphical representations of level contours, terrain cuts, topographic profiles and embankments. The terrains textures used are satellite photos available by the Digital Globe platform and contribute to improve the visualization of studied concepts. Developed environments enable students to view surfaces in AR ambient, using their webcam devices, such as smartphones, tablets, or notebooks, from a variety of points of view. Each topographic surface mockup has a link to its respective representation in VR, which allows its manipulation and detailed study of each concept. The environments presented in this work can be used in disciplines of Topography, Geography and Descriptive Geometry.

The article validates the terms based on the notion of reality that have started to be used in the media due to the implementation of digital technologies. Emphasis is laid on Virtual Reality (VR) and its types: Augmented Reality (AG) and Mixed Reality (MR). Дєіг application updates the approaches to the creation of film and TV productions, alters the immanent bond with the audience. tte terms are correlated with the concepts of media reality and screen reality introduced into scientific use. As a result, there emerges a multireality which affects the individuals perception.

<p><strong>Abstract.</strong> One of the challenges of the Digital Cultural Heritage (DCH) field is the creation of coherent HBIMs and the dissemination of the collected historical data. The latest development of new technologies has the great potential to realise virtual content-based immersive experiences that are easily available by both experts and non-expert users. On the other hand, they require specific skills and a holistic approach to the study of the building that involves different disciplines.</p><p>The research that has been carried out for the last five years on one of the greatest monuments in Milan, the Basilica of Sant'Ambrogio, adopted this comprehensive methodology. Although the church is a very well-known building, its turbulent history remains in a certain aspect hidden to the large public. This paper shows the workflow that has been developed for the Basilica, starting from the 3D survey to the historical data acquisition and the study on the church itself, based on a ‘virtual subtraction process’, till the creation of a Virtual Reality experience. This one is the first step of a wider project on eXtended reality (Virtual/Mixed/Augmented Reality) that intends to make the gathered knowledge of the Basilica available to the public.</p>

Getrieben durch populäre Produkte und Anwendungen wie Oculus Rift, Pokémon Go oder der Samsung Gear stößt Virtual Reality, Augmented Reality und auch Mixed Reality auf zunehmend großes Interesse. Obwohl die zugrunde liegenden Technologien bereits seit den 1990er Jahren eingesetzt werden, ist eine breitere Adoption erst seit relativ kurzer Zeit zu beobachten. In der Folge ist ein sich schnell entwickelndes Ökosystem für VR und AR entstanden (Berg & Vance, 2017). Aus einer (medien-) politischen Perspektive interessiert dabei, welche Standortfaktoren die Ansiedlung und Agglomeration dieser Firmen begünstigen. Da die Wertschöpfungsaktivitäten sowohl hinsichtlich der Zielmärkte als auch der Leistungserstellung (z. B. starker Einsatz von IT und Hardware in der Produkterstellung) von denen klassischer Medienprodukte deutlich abweichen, kann insbesondere gefragt werden, ob die VR-, MR- und AR-Unternehmen mit Blick auf die Ansiedlungspolitik als Teil der Medienbranche aufzufassen sind und somit auf die für Medienunternehmen besonders relevanten Faktoren in ähnlichem Maße reagieren. Der vorliegende Aufsatz ist das Ergebnis eines Forschungsprojekts im Auftrag des Mediennetzwerks NRW, einer Tochterfirma der Film- und Medienstiftung NRW.
