The digital age is characterized by hyperconnected services. Whenever we engage with an app we likely engage with a broader set of actors, often facilitated by a platform. Essentially, we engage with a service ecosystem posing particular challenges for privacy regulation. With GDPR taking effect we seek to understand the implications of it for privacy in such ecosystems. Interconnected services can facilitate the diffusion of personal data and thus impede with individual privacy rights. We apply a novel techno-legal analysis to the flow of personal information in service ecosystems. Based on two cases, we show that novel requirements arise for platforms as key actors in service ecosystems. Using our techno-legal analysis we conclude that two major platform providers, Apple and Facebook, have more in common from a legal perspective than the current rhetoric suggests. Based on the analysis, we discuss where privacy-preserving solutions in service ecosystems need to be positioned.

Smart cities and communities aim for social wellbeing. Mobilizing and integrating various institutions, actors, and resources are crucial when building and instantiating smart community initiatives. The design of such an arrangement is a complex phenomenon, difficult to conduct systematically and to observe empirically. We address this challenge by applying a multilevel design framework for service systems to an ongoing design science research project. The research project pursues the goal of building a neighborhood community as an instantiation of smart communities by activating and leveraging local institutions, actors, and resources on an IT-enabled engagement platform. We demonstrate how this multilevel perspective informs the design process for building smart communities. Based on micro-level observations, the interdependence of engagement-stimulating mechanisms related to the platform's design at the meso-level, and design implications for the institutional arrangement at the macro-level are emphasized as inseparable design activities for mobilizing and integrating actors and resources.

Far-reaching digitalization affords significantly more opportunities for engaging actors and mobilizing resources in service systems. By leveraging these capabilities, digitally enabled service systems can facilitate user-generated services. Traditional service engineering approaches provide for such service systems. This paper presents and discusses the evaluation of a field-based design science research project for designing an engagement platform that facilitates the co-creation of user-generated services. This study reports contributions to the design knowledge of such an engagement platform and their consequences for engagement activities. Based on the evaluation, we propose design propositions for such an engagement platform from a sociotechnical perspective.

The rapid evolution of augmented reality has resulted in an ever-increasing number of applications in a wide range of industries and services. Despite this progress, there is still a lack of conceptual understanding of AR interactions and the entire solution space. To bridge this gap, we conceptualize AR solution interactions and provide a comprehensive taxonomy. To represent the state-of-the-art, we build upon an extensive literature review. The resulting taxonomy consists of seven dimensions that encompass 29 characteristics. We contribute to the understanding of AR interactions and, as a result, the applicability of AR solutions in businesses by developing the taxonomy. Likewise, the taxonomy can guide the design of AR solutions as it convincingly describes the solution space.

ZusammenfassungAugmented 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.
