Reuter, C., Ludwig, T., Friberg, T., Pratzler-Wanczura, S. & Gizikis, A. (2015)Social Media and Emergency Services? Interview Study on Current and Potential Use in 7 European Countries
IN International Journal of Information Systems for Crisis Response and Management (IJISCRAM), Vol. 7, Pages: 36–58 doi:10.4018/IJISCRAM.2015040103
[BibTeX] [Abstract] [Download PDF]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.

Reuter, C., Ludwig, T., Kaufhold, M. & Pipek, V. (2015)XHELP: Design of a Cross-Platform Social-Media Application to Support Volunteer Moderators in Disasters
Proceedings of the Conference on Human Factors in Computing Systems (CHI). Seoul, Korea, Publisher: ACM Press, Pages: 4093–4102 doi:10.1145/2702123.2702171
[BibTeX] [Abstract] [Download PDF]Recent disasters have shown an increase in the significance of social media for both affected citizens and volunteers alike in the coordination of information and organization of relief activities, often independently of and in addition to the official emergency response. Existing research mainly focuses on the way in which individual platforms are used by volunteers in response to disasters. This paper examines the use of social media during the European Floods of 2013 and proposes a novel cross-social-media application for volunteers. Besides comprehensive analysis of volunteer communities, interviews were conducted with “digital volunteers” such as Facebook moderators of disaster-related groups. Based on the challenges identified, we designed and implemented the cross-social-media application “XHELP”, which allows information to be both, acquired and distributed cross-media and cross-channel. The evaluation with 20 users leads to further design requirements for applications aiming to support volunteer moderators during disasters.

IN i-com: Journal of Interactive Media, Vol. 15, Pages: 249–264 doi:10.1515/icom-2016-0036
[BibTeX] [Abstract] [Download PDF]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.

[BibTeX] [Abstract] [Download PDF]Social media and instant messaging services are nowadays considered as important communication infrastructures on which people rely on. However, the exchange of content during breakdowns of the underlying technical infrastructures, which sometimes happens based on environmental occurrences, is challenging. Hence, with this paper, we examine the resilience of social media during breakdowns. We discuss communication options and examine ad-hoc functionality for the exchange of social media data between different actors in such cases. To address this, we have developed a concept, which makes use of mobile ad-hoc networks (MANETs) for the spontaneous exchange of information with smartphones. We implemented our concept as the mobile application Social Offline Map (SOMAP) and evaluated it within two iterations (1.0 and 2.0). Finally, we discuss our contribution within the context of related work and the limitations of our approach.

Mensch und Computer 2018 – Workshopband. doi:10.18420/muc2018-ws07-0378
[BibTeX] [Abstract] [Download PDF]Zusammenfassung In der heutigen Zeit sind Meetings nicht mehr physisch an einen Ort gebunden. Vor allem in der Wis-sensarbeit ergänzen Telefonate oder Skype-Konferenzen bereits seit langem klassische Face-to-Face-Meetings. Verschiedene Forschungsdiskurse, vor allem der computerunterstützten Gruppenarbeit, unter-suchen bereits seit nun mehr fast drei Jahrzehnten, wie durch den Einsatz von IT verteilte Gruppenarbeit in ihren verschiedensten Ausprägungen unterstützt werden kann. Mit zunehmender Leistungsfähigkeit von Technologien mit Fokus auf Augmented Reality (AR) sowie Virtual Reality (VR) sind neue Mög-lichkeiten hinzugekommen, die ein hohes Potential zur Unterstützung verteilter Meetings bieten. In die-sem Paper stellen wir einen Ansatz vor, der durch die Kombination von AR und VR ein Kommunikati-onssystem mit verschiedenen Kollaborationsmöglichkeiten zur geeigneten Unterstützung verteilter Meetings umsetzt und durch den Einsatz von Consumer-Hardware auch für die Arbeit von zu Hause geeignet ist. Der Mehrwert des Ansatzes liegt vor allem darin, dass auch solche Szenarien fokussiert werden, bei denen sich zwei oder mehr Personen in demselben Raum befinden sowie ein oder mehrere Personen nicht anwesend sind und entfernt zur selben Zeit kooperieren.

In die-sem Paper stellen wir einen Ansatz vor, der durch die Kombination von AR und VR ein Kommunikati-onssystem mit verschiedenen Kollaborationsmöglichkeiten zur geeigneten Unterstützung verteilter Meetings umsetzt und durch den Einsatz von Consumer-Hardware auch für die Arbeit von zu Hause geeignet ist. Der Mehrwert des Ansatzes liegt vor allem darin, dass auch solche Szenarien fokussiert werden, bei denen sich zwei oder mehr Personen in demselben Raum befinden sowie ein oder mehrere Personen nicht anwesend sind und entfernt zur selben Zeit kooperieren.}, booktitle = {Mensch und {Computer} 2018 - {Workshopband}}, author = {Jasche, Florian and Kirchhübel, Jasmin and Ludwig, Thomas and Ogonowski, Corinna}, year = {2018}, } -

[BibTeX] [Abstract] [Download PDF]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.

However, approaches for processing and analyzing the vast quantities of data produced currently lag far behind. In this paper we discuss important steps, and the associated challenges, for processing and analyzing social media in emergencies. In our research project EmerGent, a huge volume of low-quality messages will be continuously gathered from a variety of social media services such as Facebook or Twitter. Our aim is to design a software system that will process and analyze social media data, transforming the high volume of noisy data into a low volume of rich content that is useful to emergency personnel. Therefore, suitable techniques are needed to extract and condense key information from raw social media data, allowing detection of relevant events and generation of alerts pertinent to emergency personnel.

[BibTeX] [Abstract] [Download PDF]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.

Proceedings of the Information Systems for Crisis Response and Management (ISCRAM). Baden-Baden, Germany, Publisher: ISCRAM, Pages: 478–487
[BibTeX] [Abstract] [Download PDF]The electricity network is one of the most important infrastructures in modern industrialized societies. In the case of power outages, the society becomes aware of their dependence on electricity and organizations responsible for recovery work need precise information about the location and the type of the damage, which are usually not available. Unmanned Aerial Systems (UAS), commonly known as drones, are aircrafts without a human pilot on board and may help to collect this information. While many technical approaches for UAS exist, a systematic process model for using UAS in emergencies based on the organizations needs is still missing. Based on the presentation of current types of UAS, approaches of using UAS and workshops with organizations responsible for recovery work (police and fire department, public administration, power supplier) this paper presents a process model for UAS in emergencies, especially power outages, which takes both theoretical findings and human experiences into consideration.

Proceedings of the Information Systems for Crisis Response and Management (ISCRAM). Kristiansand, Norway, Publisher: ISCRAM
[BibTeX] [Abstract] [Download PDF]Maps, showing the tactical or the administrative situation at any particular time, play a central role in disaster management. They can be realized as interactive map mashups. In addition to classical information (weather, water levels, energy network, forces), they can also be used to present a view on citizen-generated content, e.g. from social media. In this paper we offer insights into how mobile map mashups can assist citizens during infrastructure failures that often occur in large-scale emergencies. Based on a review of approaches and mobile applications from literature and especially from practice, we present SOMAP (social offline map), a mobile app we developed in Android. It offers offline map functionality in terms of (A) pro-active loading and storing of potentially needed maps of the respective area as well as (B) the possibility of exchanging information from social media using Bluetooth. The application was evaluated qualitatively, to gain insights into the potential of such applications.

[BibTeX] [Abstract] [Download PDF]Emergencies such as the 2013 Central European flood or the 2013 typhoon Haiyan in Philippines have shown how citizens can organize themselves and coordinate private relief activities. These activities can be found in (physical) groups of affected people, but also within (digital) social media communities. There is an evident need, however, for a clearer picture of what exactly is going on to be available for use by the official emergency services: to enlist them, to keep them safe, to support their efforts and to avoid need-less duplications or conflicts. Aligning emergency services and volunteer activities is, then, crucial. In this paper we present a mobile crowd sensing based concept, which was designed as well as implemented as the application CrowdMonitor and facilitates the detection of physical and digital activities and the assignment of specific tasks to citizens. Finally, we outline the findings of its evaluation.

Within this paper we focus on how visualization itself can serve as a collaborative aspect within distributed and asynchronous team work. In doing so, we try to uncover challenges to support a team of researchers in understanding and analyzing mobile data by collaborative visualization. Based on a review of recent literature, two workshops with participants from the academic field were conducted, which revealed use cases and major design challenges for a collaborative visualization approach. With our user-centered study, we introduce design implications for collaborative visualizations that focus on research questions instead on single visualizations, embed multiple visualizations into a discussion thread, highlight relations between research artefacts as well as include external parties in collaborative visualizations.

IN ACM Transactions on Computer-Human Interaction (ToCHI), Vol. 21, Pages: 26:1–26:26 doi:10.1145/2651365
[BibTeX] [Abstract] [Download PDF]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.

[BibTeX] [Abstract] [Download PDF]Decisions of emergency response organisations (police, fire fighters, infrastructure providers, etc.) rely on accurate and timely information. Some necessary information is integrated into control centre’s IT (weather, availability of electricity, gauge information, etc.), but almost every decision needs to be based on very specific information of the current crisis situation. Due to the unpredictable nature of a crisis, gathering this kind of information requires much improvisation and articulation work which we aim to support. We present a study on how different emergency response organisations communicate with teams on-site to generate necessary information for the coordinating instances, and we described, implemented and evaluated an interaction concept as well as a prototype to support this communication by a semi-structured request-and-report system based on Android devices. We learned that (1) the accuracy of request and reports can be improved by using an appropriate metadata structure in addition to creating multimedia-based information content, (2) requirements of trusted and fast information need to be respected in support concepts although they may even be contradictory, and (3) the coordination strategy of the emergency response organisation also shapes the way this interaction needs to be designed.

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

[BibTeX] [Abstract] [Download PDF]To be able to take efficient measures in crisis management, it is essential for emergency services to get as much details about an actual situation on-site as possible. Currently content from social media plays an important role since those platforms are used to spread crisis-relevant data within the population. Our contribution presents a concept which supports the situation assessment practices of emergency services by collaboratively evaluating and by analyzing citizen-generated content from social media using a multi-touch table. The concept was implemented based on a Microsoft PixelSense and evaluated with 14 participants. The results reveal the impact of subjectivity of the participants, their positioning around the table as well as the uniqueness of social media posts on the collaborative situation assessment with multi-touch tables

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.

[BibTeX] [Abstract] [Download PDF]The amount of data being available is increasing rapidly. Based on the technological advances with mobile and ubiquitous computing, the use of social media is getting more and more usual in daily life as well as in extraordinary situations, such as crises. Not surprisingly, this increasing use is one reason why data on the internet is also developing that fast. Currently, more than 3 billion people use the internet and the majority is also registered with social media services such as Facebook or Twitter. While processing this kind of data by the majority of non-technical users, concepts of End-User Development (EUD) are important. This chapter researches how concepts of EUD might be applied to handle social big data. Based on foundations and an empirical pre-study, we explore how EUD can support the gathering and assessment process of social media. In this context, we investigate how end-users can articulate their personal quality criteria appropriately and how the selection of relevant data can be supported by EUD approaches. We present a tailorable social media gathering service and quality assessment service for social media content, which has been implemented and integrated into an application for both volunteers and the emergency services.

IN ACM Transactions on Computer-Human Interaction (ToCHI), Vol. 21, Pages: Article 17 doi:10.1145/2749461
[BibTeX] [Abstract] [Download PDF]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.

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.}, number = {4}, journal = {ACM Transactions on Computer-Human Interaction (ToCHI)}, author = {Ludwig, Thomas and Reuter, Christian and Pipek, Volkmar}, year = {2015}, keywords = {CSCW, HCI, PRAXLABS, A-Paper, EmerGent, SMO, MdK}, pages = {Article 17}, } -

[BibTeX] [Abstract] [Download PDF]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.

[BibTeX] [Abstract] [Download PDF]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′.

[BibTeX] [Abstract] [Download PDF]The increasing functionalities and close integration of hardware and software of modern cyber-physical systems present users with distinct challenges in applying and, especially, appropriating those systems within their practices. Existing approaches to design for appropriation and the development of sociable technologies that might support users seeking to understand how to make such technologies work in a specific practice, often lack appropriate user interfaces to explain the internal and environment-related behavior of a technology. By taking the example of 3D printing, we examine how augmented reality can be used as a novel human–machine interface to ease the way for hardware-related appropriation support. Within this paper we designed, implemented and evaluated a prototype called PrintARface, that extends a physical 3D printer by incorporating virtual components. Reflections upon the evaluation of our prototype are used to provide insights that foster the development of hardware-related appropriation support by encompassing augmented reality-based human–machine interfaces.

[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.

[BibTeX] [Abstract] [Download PDF]Consumer purchase decisions are not only determined by the quality or price of a product. Customers also want an innovative product that they can identify with in something more than just a functional way. Much of this appeal is often bound up with the innovative character of a product. However, the global market and the huge variety of products available make it challenging for companies to help customers understand the particular innovations in their products, especially in terms of technical “hidden” innovations. Augmented reality (AR) offers interactive experiences in real-world environments through digitalized information. In this paper, we present a design case study about an AR-based approach to reveal the hidden innovations to potential users in an engaging and “emotional” way by using the example of a vacuum cleaner. Based on an empirical study, we designed and implemented the fully functional HoloLens application VacuumCleanAR, which allows users to discover the hidden innovations of a vacuum cleaner in a less functional and more consumer-centric way. This reveals the scope for augmenting other physical artifacts in a similar fashion.

[BibTeX] [Abstract] [Download PDF]Research on food practices and technology use is becoming more common, albeit with a constant technological determinism with respect to the support of individual practices. Nevertheless, there are only a few empirical studies that outline the use of current technologies within eating contexts. We therefore conducted an empirical study on the practice of eating out and the use of mobile technologies before, during, and after eating. Our investigation consists of a qualitative interview study (n=29) complemented by a large observational study (n=458) within several restaurant settings. Our results indicate a strong reluctance to use technology while eating and highlights several design spaces focusing on before and after the actual eating. Within our paper, we uncover a strong relationship between smartphone use and the social settings in which the interaction takes place. We contribute to the emerging research field of Human-Food Interaction by outlining design spaces for supporting practices around food consumption when eating out.

It’s our hope this is a step toward helping us design better technology and user experiences to support the accomplishment of that work, while paying attention to workplace context. Despite advancement and investment in Machine Learning (ML) business applications, understanding workers in these work contexts have received little attention. As this category experiences dramatic growth, it’s important to better understand the role that workers play, both individually and collaboratively, in a workplace where the output of prediction and machine learning is becoming pervasive. There is a closing window of opportunity to investigate this topic as it proceeds toward ubiquity. CSCW and HCI offer concepts, tools and methodologies to better understand and build for this future.

[BibTeX] [Abstract] [Download PDF]Digital fabrication technologies, such as 3D printers, are receiving more and more attention, not only from professionals but also from hobbyists. However, even though people have easier access to these devices, 3D printers remain a black box for many users. To support the appropriation of 3D printers, this demonstration presents a system which extends a physical printer to include virtual components using augmented reality (AR). With these components, we try to explain how the printer works and allow the user to operate the printer through an AR application. We extend existing software with a custom solution to create a unique user interface and user experience. Our user interface provides a new way of inspecting models in AR before they are printed.

We extend existing software with a custom solution to create a unique user interface and user experience. Our user interface provides a new way of inspecting models in AR before they are printed.}, urldate = {2021-04-16}, booktitle = {Proceedings of {Mensch} und {Computer} 2019}, publisher = {Association for Computing Machinery}, author = {Jasche, Florian and Ludwig, Thomas}, month = sep, year = {2019}, keywords = {Appropriation, Human-Computer-Interaction, Sociable Technologies, 3D Printer, Augmented Reality}, pages = {901--903}, } -

IN Computer Supported Cooperative Work (CSCW), Vol. 28, Pages: 977–1000 doi:10.1007/s10606-018-9341-1
[BibTeX] [Abstract] [Download PDF]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.

[BibTeX] [Abstract] [Download PDF]What is end-user development (EUD) and when does a user become an end-user developer? Since the concept of EUD encompasses methods as well as practices of appropriating technology, it is not easy to answer these questions and several researchers already dealt with these issues. Within our chapter we suggest to conceptually extend our understanding of both EUD and the end user (developer). We draw on experiences we gained from past research exploring EUD in practice. We reflect upon the concepts of “gentle slope of complexity,” “tailoring languages” and “appropriation” which we situate within the broader concept of “infrastructuring.” We claim that EUD is given whenever an end user starts modifying the permanent aspects of an application (soft- or hardware) and, thus, starts climbing the tailorability mountain – or in our words, the tailorability staircase – and switching to a higher level to perform a specific practice. In our newly developed terminology this very moment, called “point of infrastructure,” is characterized by a break-down in the current practices which leads an end user to becoming an end-user developer.

[BibTeX] [Abstract] [Download PDF]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.

[BibTeX] [Abstract] [Download PDF]There has been recent criticism from researchers towards simple replication of traditional role models in the design of virtual agents and robots, and a call for new forms of interaction and communication with technology. By exploring the field of Human-Food interaction (HFI) – a sub-area of Human-Computer Interaction (HCI) which aims to investigate the diversity of ways people interact with food – we therefore specifically examine the design space of edible anthropomorphic virtual agents (EAVAs). To understand human-to-food interactive communication, we conducted an interview study with 19 participants, followed by a co-design workshop on the design of conversational agents for personified food. Based on the results, we implemented a prototype called FoodChattAR that employs augmented reality and chatbots to interact and communicate with food. Our evaluation with 21 participants shows that FoodChattAR turns eating into fun, while at the same time the food conveys relevant societal facts about itself. We contribute to the field of HCI by introducing EAVAs as a novel human-to-food interaction.

[BibTeX] [Abstract] [Download PDF]Developing systems to support remote collaboration usually involves creating new environments in which non-co-located participants produce actions that are, at least in part, accessible to one another. However, this typically fractures the relationship between those actions and the sense of a shared environment, engendering difficulties that can render even the simplest of activities problematic. This becomes more pronounced as the activities become more complex and involve physical artifacts. Although mixed reality seems to offer promising ways of overcoming these troubles, there is still a risk of replicating the fractured ecology problem. We report on an empirical study and the development of a mixed reality prototype called BeamLite that seeks to bypass such issues by providing participants with the illusion of them sharing a single familiar place. Although our evaluation revealed possibilities for evading some troubles associated with artifact-focused remote collaboration, it exposed the need for virtual toolboxes that dynamically support specific work practices and the importance of virtual artifacts embedded within the physical environment to further diminish the sense of ecological fracture.

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.

[BibTeX] [Abstract] [Download PDF]A variety of studies exist that design innovative interactions based on augmented reality (AR). Comparing them often involves examining their laboratory studies. However, since AR has a high context dependency (e.g., reference to the real environment), it is important to emphasize that existing literature do not reveal generalizable results regarding how to design AR instructions. Within this paper, we argue that it is time to open up new use cases and test appropriation mechanisms in practice with the help of long-term studies to build a base for the comparison of AR-based interactions. Such a repository built up with long-term studies has the potential to define valid insights for future developments in the AR environment.

However, in the case of spatial applications, practitioners from research and industry either have difficulty finding them or perceive such guides as lacking relevance, practicability, and applicability. This paper presents the current state of scientific research and industry practice by investigating currently used design recommendations for mixed reality (MR) system development. We analyzed and compared 875 design recommendations for MR applications elicited from 89 scientific papers and documentation from six industry practitioners in a literature review. In doing so, we identified differences regarding four key topics: Focus on unique MR design challenges, abstraction regarding devices and ecosystems, level of detail and abstraction of content, and covered topics. Based on that, we contribute to the MR design research by providing three factors for perceived irrelevance and six main implications for design recommendations that are applicable in scientific and industry practice.

[BibTeX] [Abstract]The Octalysis framework is a gamification framework used for the design and evaluation of “human-focused” systems. Although several practitioners have applied it within their daily work, only a few academic articles have reflected on its applicability. With this study, we present how and where the framework is currently applied based on a large-scale literature study and reflect on the potentials and obstacles of using it within a Human Computer Interaction (HCI) master’s class. Our empirical findings show that the use of the Octalysis framework is often simplified and can also be overwhelming. The results further reveal that the framework itself can be helpful in the creation and evaluation of concepts, especially when extensive user research is not possible (e.g., due to time constraints). We contribute to the field of gamification by critically reflecting on the use of the Octalysis framework.

[BibTeX] [Abstract] [Download PDF]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.

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.

Kaufhold, M., Reuter, C. & Ludwig, T. (2022)Big Data and Multi-platform Social Media Services in Disaster Management
IN Singh, A. (Ed.), International Handbook of Disaster Research Singapore doi:10.1007/978-981-16-8800-3_172-1
[BibTeX] [Abstract] [Download PDF]The use of social media today is not only ubiquitous and an integral part of everyday life but is also increasingly relevant before, during, or after emergencies. Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies. This chapter presents the social media API (SMA), which is a multi-platform service for gathering big social data across different social media channels and analyzing the credibility and relevance of collected data by the means of machine learning models. Based on the lessons learned from both the implementation process and user-centered evaluations in multiple emergency settings, this chapter discusses core challenges and potentials of the SMA and similar services, focusing on (1) the multi-platform gathering and management of data, (2) the mitigation of information overload by relevance assessment and message grouping, (3) the assessment of credibility and information quality, and (4) user-centered tailorability and adjustable data operations.

Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies.
