    Die rasante Digitalisierung unserer Welt hat die Entwicklung digitaler Kompetenzen zu einem zentralen Anliegen in Wirtschaft und Gesellschaft gemacht. Während globale Akteure wie die USA, China, Südkorea und Japan in technologischen Innovationen führend sind, sieht sich die Europäische Union, insbesondere Deutschland, vor Herausforderungen gestellt, um mit dieser Innovationsdynamik Schritt zu halten, vor allem im Bereich der Informationstechnologie. Die Europäische Kommission hat als Reaktion darauf eine Digitalstrategie entwickelt, um die Wettbewerbsfähigkeit und digitale Souveränität zu stärken. Der vorliegende Beitrag untersucht, basierend auf einer retrospektiven Analyse von Beratungsfällen des Zukunftszentrums KI NRW zum Thema Digitalisierung und vor allem Künstliche Intelligenz, die digitale Kompetenzlandschaft in deutschen kleinen und mittleren Unternehmen (KMUs). Die Ergebnisse zeigen, dass ein erheblicher Bedarf an Grundlagenwissen und Verständnis für digitale Technologien besteht. Auf Basis der Ergebnisse werden Kompetenzlisten vorgestellt, die spezifische, für die digitale Arbeitswelt essentielle Fähigkeiten und Kenntnisse beinhalten. Diese Listen dienen als Grundlage, um mittels Leitfragen konkrete Handlungsempfehlungen zu formulieren, die Unternehmen bei der Bewertung und Entwicklung ihrer digitalen Kompetenzen unterstützen, um den Herausforderungen der Digitalen Transformation zu begegnen.

    A large number of mobile apps support the sustainable use of food. These apps often use playful elements to enhance the user experience and promote their long-term use. However, we know little about which conceptual aspects of gamification and which gamified elements are actually used in the context of sustainable food apps. Therefore, in this paper, we analyse 76 mobile apps from the Google Play Store found with the term ‘sustainable food’ of which we analyse 27 apps in detail using the Gameful Design Heuristics. Our analysis uncovers a low average heuristics score and an unbalanced usage of subheuristics and heuristic categories. Additionally, gamification is unevenly distributed among food themes and sustainability categories. This study’s results contribute to the research on commercial gamified apps related to sustainability and food. Thus, this paper contributes to gamification design by identifying design opportunities that serve as interesting starting points for future work.

    Abstract In recent years, emerging approaches to chatbot-guided food coaching and dietary management, while innovative and promising in nature, have often lacked long-term studies. Therefore, with this work, we pursued a participatory approach within a design case study to the co-design and development of a nutrition chatbot for elderly people. Overall, 15 participants were directly involved in the study, of which 12 participated in the initial co-design phase, seven in the first real-world evaluation study over four weeks, and three in the second evaluation study over seven weeks. We contribute to the fields of Human-Computer Interaction by showing how the long-term use of such a chatbot in the area of nutrition looks like, which design implications arise for the development of nutrition chatbots, and how a participatory design approach can be realized to design, evaluate and develop nutrition chatbots.

    [BibTeX] [Abstract] [Download PDF]

    3D printers are no longer found only in industry, universities or makerspaces but now are increasingly used in domestic settings. Personal fabrication will increase in the coming years, and 3D printing will play an important role in this process. Due to technology and price development, 3D printers are becoming established among casual users at home. However, there are still many hurdles in the use of 3D printers that interfere with their appropriation in everyday life. In this paper, we investigate how chatbots can overcome these hurdles and support onboarding to 3D printing. Furthermore, we explore how chatbots can be used as a human–machine interface and facilitate interaction with 3D printers for both novice and expert users. In a research-through-design approach, we have created a fully functional chatbot that introduces users to 3D printing and helps them perform typical tasks when operating 3D printers.

    Over the last three years, COVID-19, with its lockdowns, social restrictions, and work from home structures, had a significant influence on our daily lives. The resulting changes in technology practices are likely to be explored in the years ahead. We will contribute to this exploration by looking specifically at the impact of COVID-19 on everyday food practices and the role of involved technology. To explore food practices and technology use, we conducted a qualitative interview study with 16 interviewees and delved into the underlying influencing factors behind them. Thereby we can better understand potential behavioral changes and technology usage by people to design not only for future pandemics and exceptional situations but to also for non-pandemic times.

    [BibTeX] [Abstract] [Download PDF]

    Artificial intelligence and the underlying machine learning (ML) methods are increasingly finding their way into our working world. One of these areas is sales planning, where machine learning is used to leverage a variety of different input parameters such as prices, promotions, or the weather, to forecast sales, and therefore directly affects the production of products and goods. To satisfy the goal of environmental sustainability as well as address short shelf life, the food industry represents an interesting application field for the use of ML for optimizing sales planning. Within this paper, we will examine the design, and especially the application, of ML methods in the food industry and show the current challenges that exist in the use of such concepts and technologies from the end-user’s point of view. Our study of a smaller bakery company shows that there are enormous challenges in setting up the appropriate infrastructure and processes for the implementation of ML, that the output quality of ML processes does not always match the perceived result quality, and that trust in the functioning of the algorithms is the most important criterion for using ML processes in practice.

    Although augmented reality (AR) is becoming more common in our society, there are few specialized end-user tools for appropriate AR content creation. Most tools are focused on creating entire 3D applications or require extensive knowledge in programming and 3D modeling. With reference to End-User Development (EUD), we present a design case study for an end-user-friendly authoring tool that allows domain experts to create individual AR avatars in the field of Human-Food Interaction. After reviewing current approaches and design guidelines, we designed and implemented FADER, a web-based tool for creating AR-based food avatars. Our evaluation shows that playful design fosters immersion, and that abstract placeholders and highly simplified controls empower non-developers to create AR content. Our study contributes to a better understanding of end-user needs and practices during the AR creation process and informs the design of future AR authoring tools.

    Since almost the onset of computer-supported cooperative work (CSCW), the community has been concerned with how expertise sharing can be supported in different settings. Here, the complex handling of machines based on experience and knowledge is increasingly becoming a challenge. In our study, we investigated expertise sharing in a medium-sized manufacturing company in an effort to support the fostering of hardware-based expertise sharing by using augmented reality (AR) to ‘retrofit’ machines. We, therefore, conducted a preliminary empirical study to understand how expertise is shared in practice and what current support is available. Based on the findings, we derived design challenges and implications for the design of AR systems in manufacturing settings. The main challenges, we found, had to do with existing socio-technical infrastructure and the contextual nature of expertise. We implemented a HoloLens application called RetrofittAR that supports learning on the production machine during actual use. We evaluated the system during the company’s actual production process. The results show which data types are necessary to support expertise sharing and how our design supports the retrofitting of old machines. We contribute to the current state of research in two ways. First, we present the knowledge-intensive practice of operating older production machines through novel AR interfaces. Second, we outline how retrofitting measures with new visualisation technologies can support knowledge-intensive production processes.

    [BibTeX] [Abstract] [Download PDF]

    10 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.

    While crowds online are increasingly used for data gathering and problem solving, the relationships and structures within these processes remain largely unexamined. For understanding the usage of crowdsourcing and to design appropriate technologies and processes, it is important to understand how different tools support relationships in these contexts. Based on an extensive literature review of existing crowdsourcing tools and practices, we contribute with the development of a typology of alienation in crowdsourcing by using Marx’s theory of alienation. The theory serves as a lens to compare and contrast a number of currently available tools for crowdsourcing, focusing on how relationships between participants are supported and capitalized within the tool. We show how different types of crowdsourcing practices can be described in terms of alienation where the producer, the producers, the consumers, and products are connected in different modes of participation. This systematical application of Marx theory of alienation provides a way to compare the technical support for social relationships in a number of platforms used for crowdsourcing.

    3D printers have become continuously more present and are a perspicuous example of how technologies are becoming more complex and ubiquitous. To some extent, the emerging technological infrastructures around them exemplify ways how digitalization will change production machines and lines, in general, in the Internet of Things (IoT). From an End-User Development perspective, the main question is how users can be supported in managing those complex digital production lines. To reach a better understanding, we carefully analyzed 3D printers as an example of highly digitalized production machines with regard to the creative activities of their users that help them to make these machines work for their practices. In our study of appropriation processes, we are concerned with situational and social aspects of the configuration and practice challenges associated with making digitalization work and how IoT technologies can support these collaborative appropriation activities of end users by making these machines more “sociable.” We therefore conceptualize the idea of “Sociable Technologies” and implement a prototype that provides hardware-integrated affordances for communicating and documenting practices of usage. Based on the findings of our evaluation, we derive lessons learnt when aiming at making complex technologies more usable.

    Abstract Although emergency services have already recognized the importance of citizen-initiated activities during disasters, still questions with regard to the coordination of spontaneous volunteers and their activities arise. Within our article, we will present a technological approach based on public displays which aims to foster situated crowdsourcing between affected citizens, spontaneous volunteers as well as official emergency services. We will address the research question: How can the situated tasks performed by spontaneous volunteers be supported by the use of public displays during disasters? First we will present the current state of the art with regard to the coordination practices of spontaneous volunteers and emergency services within disaster situations as well as related problems, potentials and specifics of situated crowdsourcing and public displays. To gain insight into actual coordination practices, we conducted an empirical study with 18 different stakeholders involved in disaster management. Based on the literature review and our empirical study, we have derived a technical concept that supports the task and activity management of spontaneous volunteers as well as the coordination both of the demands of affected people and the offers from spontaneous volunteers. We have implemented our concept as the public display application ‘City-Share’, which provides a robust communication infrastructure and encompasses situated crowdsourcing mechanisms for managing offers and demands of activities on-the-ground. Based on its evaluation with several users, we will discuss our findings with regard to the assignment of tasks on-the-ground and situated crowdsourcing during emergencies. We outline that City-Share can improve a community’s disaster resilience, especially when focusing on the kind of collaborative resilience emerging between official stakeholders and spontaneous volunteers or affected citizens at a local level.

    Enterprises are increasingly starting to apply a user-centric perspective in their product and service development processes. This paper uses the concept of customer journey mapping (CJM) to visualize customers’ needs and perceptions throughout all of their relationships with an enterprise to improve development processes. Currently, CJM focuses more on business-to-consumer (B2C) relationships than on business-to-business (B2B) settings. In contrast, we here examine how to conceptualize a CJM template for B2B relationships by researching Bosch Packaging Technology – Business Unit Pharma, a large pharmaceutical packaging company. We employ user narratives from expert interviews, design workshops, and customer interviews/observations to visualize knowledge about customers in a CJM.

    Mobile devices have conquered nearly all parts of the daily life. These devices support their owners in specific situations, both at work and in leisure contexts, and therefore make it increasingly difficult to keep work and private life separated. Examining the practices around the use of mobile technology has become a topic of some interest as issues around “work–life balance” emerge. Although the field of HCI provides different approaches for capturing people’s activities in situ, we will show that an additional value can be obtained from a consideration of the “situated” view of contextuality, one which incorporates concerns of privacy and which identifies the reasons people might have for long-term user participation in this kind of study. Despite the undoubted sophistication of existing platforms, the issue of how to provide for dynamic adjustment to meet emerging research questions over time remains challenging. In this paper, we examine how one might approach the design of an observation environment that includes methods for understanding the way of how users reason about research, based upon the context they find themselves in. We have developed a research framework called “PartS,” which captures in situ information about the individual as well as his/her (work/personal) context and offers functionality for collaborative discussions about the information collected. Based on its evaluation, we outline six lessons that need to be considered when designing a study for capturing the subjective context and related activities from an individual user’s as well as a researcher’s perspective.

    Zusammenfassung Das aktuelle Verständnis von Industrie 4.0 umfasst oftmals die Vision einer vollautomatisierten und Technologie-determinierten Entwicklung der deutschen Industrie. Eine praktische Ausgestaltung einer solchen Vision bietet dabei keine hinreichende Option für den Mittelstand – den eigentlichen Treiber der deutschen Wirtschaft. Speziell bei kleineren und mittelständischen Unternehmen sichern die eigenen Mitarbeiter/innen sowie deren Erfahrungen und Arbeitsver-mögen maßgeblich den wirtschaftlichen Erfolg und müssen bei der Ausgestaltung von Industrie 4.0-Konzepten und -Technologien in den Fokus gerückt werden. Bei 72 T. Ludwig et al. 1 3 der Betrachtung der Mitarbeiter bzw. der Mitarbeiterinnen im Zentrum des Mittel-standes, fallen bei der praktischen Ausgestaltung von Industrie 4.0 eine Vielzahl sozialer Fragestellungen an, welche vor allem aber im Betrieb von Unternehmen und Betriebsrat bearbeitet und sozialpartnerschaftlich ausgestaltet werden müssen. In diesem Artikel werden die aktuellen Spannungsfelder präsentiert, in welchen die sozialen Fragestellungen angesiedelt sind. Diese wurden auf Basis eines Experten-workshops mit Geschäftsführern und Unternehmensberatern kleiner und mittelstän-discher Unternehmen sowie durch verschiedene Interviews mit Vertretern der IG Metall im Hinblick auf die Veränderung von Arbeit im Kontext von Industrie 4.0 erhoben.

    In recent years, citizens’ movements such as the Arab Spring or Euromaidan protests have clearly shown that, whenever affected — whether negatively or positively — by the state and government decisions, citizens act to deal with the shared issues. Groups of people who organize themselves to address (mainly political) issues were defined as a `public’ by the philosopher John Dewey. He believed it is necessary to improve communication to create a `Great Community’ as a cohesive group of a public. Although information and communication technologies (ICT) lead to ambivalent effects on pursuing this goal and often distract the mass of people from discussing these issues, we argue that nowadays ICT can improve communication and has the potential to foster the detection of issues and therefore promote the (trans-)formation of a public into an issue-based community. As our foundation we took a literature study covering the formation of publics and their potential to evolve into communities, as well as their interplay with technology. This formed the basis for the development of our operational model that `follows the issues’ for capturing the (trans-)formation of a public. Based on our model, we outline different perspectives on detecting shared issues as early indicators for publics based on ICT and derive implications for researching this process from a practical perspective.

    A growing body of research in the area of information systems for crisis management is based on data from social media. After almost every larger disaster studies emerge with the focus on the specific use of social media. Much of this research is based on Twitter data, due to the ease of access of this (mainly public) data, compared to (more closed) data, such as Facebook or Google+. Based on the experience gained from a research project on social media in emergencies and our task to collect social media data sets for other partners, we present the design and evaluation of a graphical user interface that supports those stakeholders (such as emergency services or researchers) that are interested in creating social media datasets for further crisis management research. We do not specifically focus on the analysis of social media data. Rather we aim to support the gathering process and how actors without sophisticated technical skills can be supported to get what they want and especially need: relevant social media data. Within this article, we present a practice-oriented approach and implications for designing tools that support the collection of social media data as well as future work.

    Various studies show that social media is used in emergencies – and that in spite of possible challenges for emergency services, beneficial use cases can be identified. However, relatively little empirical data is available regarding the attitudes of emergency services towards social media, and almost none of a comparative nature. This article summarizes the findings of a survey conducted of the EU project ‘EmerGent’ with 761 emergency service staff across 32 European countries from September to December 2014. The main aims of the survey were to explore the attitudes expressed by emergency service staff towards social media for private and organizational use as well as the levels and main factors influencing the current and likely future use of social media in their organizations. Based on our results, we discuss possible enhancements of the emergency management cycle using social media.

    The current understanding of `Industry 4.0′ often includes the vision of a fully-automated and technology-driven development of the German industry. But the practical configuration of such a vision is not an appropriate option for small and medium companies, which are the actual driver of the German economy. Especially for smaller and medium sized companies, the own staff, as well as their experiences and work capacity decisively secure the economic success and need to be put in the spotlight of industrial 4.0 concepts and technologies. When considering the employee as one of the central factors of success within small and medium companies, the practical adaption of fully-automated and technology-driven concepts raise a variety of social issues, which need to be addressed by the social partnership, such as employer organizations, employee organizations as well as scientific partners. This article presents the current social issues as well as areas of conflict in which these social issues are settled. Such issues were collected on the basis of an expert workshop with managers and business consultants of small and medium companies and various interviews with representatives from the labor union IG Metall and the employers’ associations in regard to the change of work in the context of `Industry 4.0′.

    Social media is much just used for private as well as business purposes, obviously, also during emergencies. Emergency services are often confronted with the amount of information from social media and might consider using them – or not using them. This article highlights the perception of emergency services on social media during emergencies. Within their European research project EMERGENT, the authors therefore conducted an interview study with emergency service staff (N=11) from seven European countries and eight different cities. Their results highlight the current and potential use of social media, the emergency service’s participation in research on social media as well as current challenges, benefits and future plans.

    People all over the world are regularly affected by disasters and emergencies. Besides official emergency services, ordinary citizens are getting increasingly involved in crisis response work. They are usually present on-site at the place of incident and use social media to share information about the event. For emergency services, the large amount of citizen-generated content in social media, however, means that finding high-quality information is similar to “finding a needle in a haystack”. This article presents an approach to how a dynamic and subjective quality assessment of citizen-generated content could support the work of emergency services. First, we present results of our empirical study concerning the usage of citizen-generated content by emergency services. Based on our literature review and empirical study, we derive design guidelines and describe a concept for dynamic quality measurement that is implemented as a service-oriented web-application “Social Haystack.” Finally, we outline findings of its evaluation and implications thereof.

    [BibTeX] [Abstract]

    Recently, digital fabrication technologies such as 3D printers have become more and more common at semi-or non-professional settings, such as university or private households. Such technologies show a high complexity and the close link between hardware and software in this field pose challenges for users how to operate them. With this paper we present first steps towards Sociable Technologies, a concept that encompass hardware with an integrated appropriation infrastructure, for supporting end users in using and understanding such rising 3D printing technologies.

    Emergencies are characterized by high complexity and unpredictability. In order to assess and manage them successfully, improvisation work and informal communication, even beyond local and organizational boundaries, is needed. Such informal practices can facilitate ad hoc participation of units in situation assessment, but this may lack overall situation awareness. This paper presents a study on how emergent ‘collaboration needs’ in current work of response teams, who are located on-site and in the control center, could be supported by mobile geo-collaboration systems. First, we present the results of an empirical study about informal work and mobile collaboration practices of emergency services. Then we describe the concept of a mobile geo-collaboration system that addresses the aspects detected in the empirical study and that was implemented as an Android application using web sockets, a technology enabling full-duplex ad hoc communication. Finally we outline the findings of its evaluation in practice and its implications.

    IN Computer Supported Cooperative Work: The Journal of Collaborative Computing (JCSCW), Vol. 23, Pages: 347–387 doi:10.1007/s10606-014-9205-2

    Emergency or crisis management, as is well-attested, is a complex management problem. A variety of agencies need to collaborate and coordinate in real-time and with an urgency that is not always present in other domains. It follows that accurate information of varying kinds (e.g. geographical and weather conditions; available skills and expertises; state-of-play; current dispositions and deployments) needs to be made available in a timely fashion to the organizations and individuals who need it. By definition, this information will come from a number of sources both within and across organizations. Large-scale events in particular necessitate collaboration with other organizations. Of course, plans and processes exist to deal with such events but the number of dynamically changing factors as well as the high number of heterogeneous organizations and the high degree of interdependency involved make it impossible to plan for all contingencies. A degree of ongoing improvisation, which typically occurs by means of a variety of information and expertise sharing practices, therefore becomes necessary. This, however, faces many challenges, such as different organizational cultures, distinct individual and coordinative work practices and discrete information systems. Our work entails an examination of the practices of information and expertise sharing, and the obstacles to it, in inter-organizational crisis management. We conceive of this as a design case study, such that we examine a problem area and its scope; conduct detailed enquiries into practice in that area, and provide design recommendations for implementation and evaluation. First, we will present the results of an empirical study of collaboration practices between organizations and public authorities with security responsibilities such as the police, fire departments, public administration and electricity network operators, mainly in scenarios of medium to large power outages in Germany. Based on these results, we will describe a concept, which was designed, implemented and evaluated as a system prototype, in two iterations. While the first iteration focuses on situation assessment, the second iteration also includes inter-organizational collaboration functionalities. Based on the findings of our evaluations with practitioners, we will discuss how to support collaboration with a particular focus on information and expertise sharing.

    Die organisationübergreifende Vernetzung von Feuerwehr, Polizei, Hilfsorganisationen, dem THW, der öffentlichen Verwaltung und Infrastrukturbetreibern, wie beispielsweise Stromnetzbetreibern, ist vor allem bei großen Schadenslagen unabdingbar. Ziel des Forschungsprojekts „InfoStrom“ (www.infostrom.org), welches vom Bundesministerium für Bildung und Forschung seit 2010 und bis Ende 2013 gefördert wird (Fö.-Kz. 13N10712), ist die Entwicklung von Konzepten sowie Software, um diese Zusammenarbeit zu unterstützten und letztlich zu verbessern. Die entstandene Software wird derzeit in zwei Kreisen in NRW, dem Kreis Siegen-Wittgenstein und dem Rhein Erft Kreis, getestet und evaluiert.
