ZusammenfassungDie Technologien Augmented Reality (AR) und Virtual Reality (VR), die mit dem Überbegriff Extended Reality (XR) zusammengefasst werden, beeinflussen die Möglichkeiten der Kommunikation und Kollaboration grundlegend. Sie können intuitiv als Schnittstelle diverser Informationsquellen genutzt werden und bieten neue Arten der Informationsdarstellung. Extended-Reality-Systeme (XRS) bauen auf diesen beiden Technologien, AR und VR, auf und haben großes Potenzial für ein breites Spektrum an Anwendungsfällen, insbesondere für Kollaborationen.Trotz dieses Potenzials ist bisher oft nicht klar, wann, wo und wie XRS sinnvoll eingesetzt werden können. Dies verzögert Innovationen und die Einführung in Arbeitsprozesse. Bei Entscheidern ist die Abgrenzung zwischen AR und VR teilweise unzureichend bekannt bzw. es fehlt die Terminologie, um die unterschiedlichen Systeme adäquat zu beschreiben. An dieser Stelle setzt diese konzeptuelle Arbeit an. Sie hat zum Ziel, das Verständnis der Anwendungsmöglichkeiten von XRS für Kollaborationen zu erleichtern sowie bei der Terminologie zu unterstützen. Aufbauend auf einer zentralen Taxonomie aus dem Bereich ‚Computer-Supported Cooperative Work‘ (CSCW) wird eine Kategorisierung von XRS für Kollaborationen entwickelt. Ein Vergleich mit bereits bestehenden Taxonomien zeigt die Notwendigkeit einer praktisch anwendbaren und unkompliziert handhabbaren Kategorisierung für die Praxis.Diese Arbeit trägt durch Kategorisierung, Terminologie und Illustrationen, zu einem besseren Verständnis von XRS-Einsatzmöglichkeiten bei. Dazu werden Illustrationen aus dem Umfeld von industriellen Baustellen genutzt.

Abstract10 years ago, Castellani et al. (Journal of Computer Supported Cooperative Work, vol. 18, no. 2–3, 2009, pp. 199–227, 2009) showed that using just an audio channel for remote troubleshooting can lead to a range of problems and already envisioned a future in which augmented reality (AR) could solve many of these issues. In the meantime, AR technologies have found their way into our everyday lives and using such technologies to support remote collaboration has been widely studied within the fields of Human-Computer Interaction and Computer-Supported Cooperative Work. In this paper, we contribute to this body of research by reporting on an extensive empirical study within a Fab Lab of troubleshooting and expertise sharing and the potential relevance of articulation work to their realization. Based on the findings of this study, we derived design challenges that led to an AR-based concept, implemented as a HoloLens application, called shARe-it. This application is designed to support remote troubleshooting and expertise sharing through different communication channels and AR-based interaction modalities. Early testing of the application revealed that novel interaction modalities such as AR-based markers and drawings play only a minor role in remote collaboration due to various limiting factors. Instead, the transmission of a shared view and especially arriving at a shared understanding of the situation as a prerequisite for articulation work continue to be the decisive factors in remote troubleshooting.

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.

Critical Investigation

The study of computing infrastructures has grown significantly due to the rapid proliferation and ubiquity of large-scale IT-based installations. At the same time, recognition has also grown of the usefulness of such studies as a means for understanding computing infrastructures as material complements of practical action. Subsequently the concept of “infrastructure” (or “information infrastructures,” “cyberinfrastructures,” and “infrastructuring”) has gained increasing importance in the area of Computer-Supported Cooperative Work (CSCW) as well as in neighboring areas such as Information Systems research (IS) and Science and Technology Studies (STS). However, as such studies have unfolded, the very concept of “infrastructure” is being applied in different discourses, for different purposes, in myriad different senses. Consequently, the concept of “infrastructure” has become increasingly muddled and needs clarification. The chapter presents a critical investigation of the vicissitudes of the concept of “infrastructure” over the last 35 years.

Crucial Question

The emergence of practice-centered computing (e.g., Computer-Supported Cooperative Work, or CSCW) raises the crucial question: How can we conceptualize the practices into which the prospective technology is to be integrated? How can we, reasonably, say of two observed activities or events that they are, or are not, instances of the same type? These are crucial questions. This chapter therefore attempts to clarify the concepts of “practice” and “technique.” First, since our ordinary concepts of “practice” and “technique” developed as part of the evolution of modern technology, as tools for practitioners’ and scholars’ reflections on the role of technical knowledge in work, the chapter outlines the major turning points in the evolution of these concepts, from Aristotle (via the scholastics), to enlightenment thinkers such as Diderot and Kant, and finally to Marx and Marxism. The chapter thereafter moves on to analyze the concepts as we use them today in ordinary discourse.

Meta Analyses

Background: The application of virtual and augmented reality technologies to orthopaedic surgery training and practice aims to increase the safety and accuracy of procedures and reducing complications and costs. The purpose of this systematic review is to summarise the present literature on this topic while providing a detailed analysis of current flaws and benefits. Methods: A comprehensive search on the PubMed, Cochrane, CINAHL, and Embase database was conducted from inception to February 2021. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. The Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomized Studies (MINORS) was used to assess the quality and potential bias of the included randomized and non-randomized control trials, respectively. Results: Virtual reality has been proven revolutionary for both resident training and preoperative planning. Thanks to augmented reality, orthopaedic surgeons could carry out procedures faster and more accurately, improving overall safety. Artificial intelligence (AI) is a promising technology with limitless potential, but, nowadays, its use in orthopaedic surgery is limited to preoperative diagnosis. Conclusions: Extended reality technologies have the potential to reform orthopaedic training and practice, providing an opportunity for unidirectional growth towards a patient-centred approach.
