    Anforderungen sicherheitskritischer Dienste an Augmented Reality-Lösungen – Wassertiefenmessung in einem Seehafen
    (HMD Praxis der Wirtschaftsinformatik: Vol. 59, No. 1, 2022) Bräker, Julia; Osterbrink, Anna; Wiesche, Manuel; Semmann, Martin
    Augmented Reality ist eine zunehmend weiter verbreitete Technologie. Die Potenziale in Bereichen außergewöhnlich hoher kognitiver Anforderungen in sicherheitskritischen Kontexten sind bisher allerdings wenig untersucht. Insbesondere Dienstleistungen, die umfassendes Fachwissen voraussetzen, sicherheitskritisch sind und parallel auszuführende Aufgaben erfordern, können durch den Einsatz von Augmented Reality in ihrer Ausführung unterstützt werden. In solchen Dienstleistungen ermöglicht Augmented Reality eine nahtlose Integration wesentlicher Informationen in das Sichtfeld der Nutzenden. Beim Einsatz von Head-Mounted Displays kann zudem eine freihändige Interaktion erfolgen. Diese Arbeit untersucht die nutzerzentrierten Anforderungen an Augmented Reality-Lösungen in einem sicherheitskritischen Bereich im Betrieb eines großen europäischen Seehafens. Konkret geht es um Wassertiefenmessung des gesamten Hafengebiets zur Instandhaltung der Hafeninfrastruktur. Basierend auf elf Think-Aloud-Sitzungen während der Messfahrten, zwei Experteninterviews und zwei Expertenworkshops, wurden fünf Anforderungen an Augmented Reality bei der Wassertiefenmessung abgeleitet, die eine Lösung zur Unterstützung der Dienstleistung erfüllen sollte. Unseres Wissens nach präsentieren wir damit die erste Studie zur Anwendbarkeit und Umsetzbarkeit von Augmented Reality in der maritimen Industrie und identifizieren Anforderungen, die sich auf die weitere Forschung zum Einsatz von Augmented Reality in sicherheitskritischen Umgebungen übertragen lassen. Augmented reality is an increasingly widespread technology. However, the potentials in areas with extraordinarily high cognitive requirements in safety-critical environments have received little attention so far. Services that necessitate extensive expertise, are safety-critical, and require the completion of concurrent tasks can be supported using augmented reality. In such cases, augmented reality enables the augmentation of service provision by giving seamless integration of information directly into the field of view while permitting for hands-free interaction in the case of head-mounted displays. This research investigates the user-centered requirements for augmented reality solutions in a safety-critical area in the operations of a large European seaport. It specifically addresses the measurement of water depths throughout the entire port area for maintenance of port infrastructure. Based on eleven think-aloud sessions during the process of water depth management, two expert interviews and two expert workshops, five requirements for augmented reality were derived that solution should fulfil to support the service. As a result, we present the first study on the applicability and practicability of augmented reality in the marine industry and provide the foundation for future research on the use of augmented reality in safety-critical contexts.

    A Classification Framework for Service Modularization Methods
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 14, 2018) Pöppelbuß, Jens; Lubarski, Aleksander
    Service modularity has been suggested as a promising concept that can resolve the dilemma between increasing diversification of customer demands and the provider’s need for standardization and efficiency gains. Despite having been in the center of attention amongst service researchers for the past decade, service modularity still remains a rather theoretical concept with little application in practice. Previous publications have contributed conceptual and enterprise modeling methods to achieve modular service architectures by both adjusting product modularization methods to the service domain as well as designing new ones specifically for services. However, up to date, there exists no framework that would systematize and classify these methods concerning their premises as well as underlying modularity principles and objectives. The main contribution of this paper is the development of a framework that can be used to classify existing and future methods for service modularization based on two key dimensions, i. e., the phases of the modularization process and the types of structuring the modular architecture. The developed framework further points out which phases of the overall modularization process are still underdeveloped and how future research can contribute to making service modularity more accessible for practitioners.
