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.

XHELP: Design of a Cross-Platform Social-Media Application to Support Volunteer Moderators in Disasters

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.

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]

Im Falle von Stromausfällen kommt der Kommunikation von Stromnetzbetreibern bzw. Behörden und Organisationen mit Sicherheitsaufgaben (BOS) mit der Bevölkerung eine besondere Bedeutung zu, da durch strombezogene Ausfälle vieler Kommunikationsinfrastrukturen die klassischen Kommunikationsmedien oftmals nicht in ihrer Gänze genutzt werden können. In diesem Beitrag werden technische Alternativkonzepte zur Unterstützung der Krisenkommunikation bei Ausfall der Stromversorgung untersucht. Hierzu werden zuerst die Wahrnehmung von Stromausfällen durch Bürger und deren Informationsbedarfe dargestellt und anschließend Kommunikationsinfrastrukturen sowie deren Verfügbarkeit in verschiedenen Stromausfallszenarien analysiert. Hierauf aufbauend wird das Konzept einer Smartphone-Applikation vorgestellt, welches die Zeit zwischen Eintreten des Stromausfalls und einer möglichen oder zeitweisen Überlastung des Mobilfunknetzes adressiert und mit potentiellen Nutzern evaluiert wurde. Ziel war es, Erkenntnisse über mögliche mobilfunkbasierte Unterstützungskonzepte zu gewinnen und Design-Vorschläge zur Umsetzung solcher Konzepte zu geben.

Kooperationstechnologien spielen in sicherheitskritischen Systemen eine große Rolle, da in vielen Anwendungsfeldern nicht nur die Interaktion von Mensch und Computer, sondern auch die durch IT unterstützte Kooperation zwischen Menschen notwendig ist, um Aufgaben bewältigen zu können. Solche Technologien müssen verschiedene Anforderungen erfüllen und können ebenfalls zur Resilienz beitragen. Unter Resilienz durch Kooperation verstehen wir die Fähigkeit, Krisen durch die Anpassungsfähigkeit an geänderte Realitäten ohne nachhaltigen Schaden mithilfe von Kooperation zu überstehen. Während das Konzept der Resilienz in den Ingenieurwissenschaften vornehmlich die Verfügbarkeit technischer Systeme fokussiert, betrachten wir Resilienz als soziotechnisches Konstrukt, unter expliziter Betrachtung der beteiligten Akteure. Basierend auf Grundlagen zu Kooperationstechnologien zeigt unser Kapitel anhand von praktischen exemplarisch umgesetzten Kooperationstechnologien (soziales Netzwerk, GIS-System, Smartphone Apps, Facebook App und Social Media Analytics-Plattform), wie Kooperation unterstützt wird und zu kooperativer Resilienz beitragen kann.

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.

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.

abstract = {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.},

Informatik 2014 – Big Data – Komplexität meistern: 2014 Stuttgart, Germany. .
[BibTeX] [Abstract] [Download PDF]

Dieser Beitrag soll aufzeigen, wie ein anpassbarer Bewertungsdienst die Nutzung bürgergenerierter Inhalte aus sozialen Medien unterstützen kann. Dabei soll insbesondere geklärt werden, wie dieser gestaltet werden kann und wie Nutzer die Qualitätskriterien angemessen artikulieren können. Nach einer Darstellung von Grundlagen und verwandten Arbeiten wird anhand einer empirischen Vorstudie der Umgang von Behörden und Organisationen mit Sicherheitsaufgaben (BOS) mit bürgergenerierten Informationen betrachtet. Basierend auf den dort gewonnen Erkenntnissen wurde ein service-orientierter Bewertungsdienst entwickelt und in eine Anwendung integriert, welche so den Zugang zu bürgergenerierten Informationen aus verschiedenen sozialen Medien inklusive einer anpassbaren Qualitätsbewertung ermöglicht. Eine abschließende Evaluation illustriert deren mögliche Anwendung in der Praxis.

From Publics to Communities: Researching the Path of Shared Issues Through ICT
Ludwig Thomas, Reuter Christian, Pipek Volkmar

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.

Strategy for Processing and Analyzing Social Media Data Streams in Emergencies
Moi Matthias, Friberg Therese, Marterer Robin, Reuter Christian, Ludwig Thomas, Markham Deborah, Hewlett Mike, Muddiman Andrew
Proceedings of the International Conference on Information and Communication Technologies for Disaster Management (ICT-DM): 2015 Brest, France. .
[BibTeX] [Abstract] [Download PDF]

People are using social media to a greater extent, particularly in emergency situations. 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.

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.

Mensch-Computer-Interaktion und Social Computing spielen auch in Krisensituationen eine große Rolle. Durch die größere Verbreitung mobiler und ubiquitärer Technologien sowie die zunehmende Durchdringung sozialer und kooperativer Medien im Alltag haben sich auch im Bereich des Krisenmanagements und der zivilen Sicherheitsforschung neue Möglichkeiten und Potenziale, aber auch Problembereiche entwickelt, die besonderer Aufmerksamkeit bedürfen. Neue Ansätze und Prototypen adressieren Interaktionen und Kooperationen innerhalb und zwischen klassischen Behörden und Organisationen mit Sicherheitsaufgaben (BOS), aber zunehmend auch die Einbeziehung der von der Krise betroffenen Akteure aus den Bereichen der Industrie und der Bürger, die eine Rolle als aktive Krisenmanager wahrnehmen und BOS unterstützen.

Mobiler Reporting-Mechanismus für örtlich verteilte Einsatzkräfte
Ludwig Thomas, Reuter Christian, Pipek Volkmar
Mensch & Computer: Tagungsband: 2013 Bremen, Germany. .
[BibTeX] [Abstract] [Download PDF]

Die im Katastrophenschutz beteiligten Behörden und Organisationen mit Sicherheitsaufgaben (BOS) benötigen für Entscheidungen eine aktuelle und akkurate Informationsbasis. Einige dieser Informationen, z.B. Wetterinformationen, können über externe Dienste in Leitstellensystemen visualisiert werden. Andere müssen seitens der zuständigen Einheiten vor Ort via Funk gemeldet werden. Unsere Design-Fallstudie untersucht interaktive Unterstützungsmöglichkeiten dieser Reporting-Prozesse: In einer qualitativen empirischen Studie wurden die Kommunikationspraktiken von Polizei und Feuerwehr untersucht. Darauf aufbauend wurde ein Konzept zur semi-strukturierten Artikulation von Informationsbedarfen erstellt, welches als mobile Android Applikation implementiert und mit potentiellen Nutzern evaluiert wurde. Unser Beitrag illustriert, wie zielgerichtete Informationsanfragen unter Berück-sichtigung angemessener Metadaten das Reporting örtlich verteilter Einsatzkräfte unterstützen können.

Design of a Process Modell for Unmanned Aerial Systems (UAS) in Emergencies
Thamm Hans-Peter, Ludwig Thomas, Reuter Christian

[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.

Die Analyse sozialer Medien hat eine enorme Bedeutung für die verschiedensten Bereiche, wie bei-spielsweise die Lagebeurteilung, journalistische Recherchen oder unternehmerische Analysen. Dabei sind die entsprechenden Analysten unterschiedlichen Kontextfaktoren unterworfen. Sei es durch ihren organisationalen Hintergrund, durch tätigkeitsbezogene Rollen oder den geografischen und zeitlichen Rahmen. Um den ständig im Wandel begriffenen Kontexten gerecht zu werden, ergeben sich permanent neue Herausforderungen für die Anpassbarkeit der Analyse. Dieser Beitrag untersucht, wie ein auf Machine Lear-ning (ML) basierendes Tool zur Social Media Analyse (SMA) im Sinne des End-User Development (EUD) auf verschiedenen Komplexitäts- und Schrittebenen umgesetzt werden kann.

Proceedings of the Information Systems for Crisis Response and Management (ISCRAM): 2015 Kristiansand, Norway. .
[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.

Hierbei kann ein Lehr- und Fachbuch, wie dieses, immer nur einen punktuellen Stand abdecken. Dennoch kann der Versuch unternommen werden, aktuelle Trends zu identifizieren und einen Ausblick in die Zukunft zu wagen. Genau das möchte dieses Kapitel erreichen: Es sollen zukünftige Entwicklungen vorausgesagt und versucht werden, diese korrekt einzuordnen. Das ist an dieser Stelle nicht nur durch den Herausgeber, sondern durch Abfrage bei zahlreichen am Lehrbuch beteiligten Autoren geschehen. Neben einem Ausblick auf Grundlagen und Methoden werden dementsprechend auch sicherheitskritische interaktive Systeme und sicherheitskritische kooperative Systeme abgedeckt.

CrowdMonitor: Mobile Crowd Sensing for Assessing Physical and Digital Activities of Citizens during Emergencies

[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.

Visualizations are mainly used for providing easy access to complex information and data. 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.

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.

What You See Is What I Need: Mobile Reporting Practices in Emergencies
Ludwig Thomas, Reuter Christian, Pipek Volkmar
Proceedings of the European Conference on Computer Supported Cooperative Work (ECSCW): 2013 Paphos, Cyrus. . doi:10.1007/978-1-4471-5346-7_10

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.

Information and Expertise Sharing in Inter-Organizational Crisis Management
Ley Benedikt, Ludwig Thomas, Pipek Volkmar, Randall Dave David, Reuter Christian, Wiedenhoefer Torben
Computer supported cooperative work: the journal of collaborative computing (jcscw) 2014;23(4-6):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.

Während das Konzept der Resilienz in den Ingenieurwissenschaften vornehmlich auf die Verfügbarkeit technischer Systeme fokussiert ist, betrachtet unser Beitrag Resilienz als soziotechnisches Konstrukt und zeigt Möglichkeiten zur Förderung kooperativer Resilienz, insbesondere durch Kooperationstechnologie, auf. Nach einer Definition von Resilienz im Allgemeinen und im Katastrophenschutz – unserem Anwendungsfeld – sowie im Kontext kooperativer Strukturen, stellen wir unsere Methodik und die entwickelten Kooperationstechnologien vor. Diese adressieren die Zusammenarbeit verschiedener Akteure (z. B. Feuerwehr, Polizei, Bevölkerung) in Schadenslagen. Abschließend diskutieren wir den Beitrag dieser Technologien zur kooperativen Resilienz als Fähigkeit, Krisen der Kooperation durch Anpassungsfähigkeit an geänderte Realitäten mithilfe von Kooperationstechnologie zu überstehen.

Mensch-Computer-Interaktion und Social Computing spielen auch in Krisensituationen eine große Rolle. Durch die größere Verbreitung mobiler und ubiquitärer Technologien sowie die zunehmende Durchdringung sozialer und kooperativer Medien im Alltag haben sich auch im Bereich des Krisenmanagements und der zivilen Sicherheitsforschung neue Möglichkeiten und Potenziale, aber auch Problembereiche entwickelt, die besonderer Aufmerksamkeit bedürfen. Neue Ansätze und Prototypen adressieren Interaktionen und Kooperationen innerhalb und zwischen klassischen Behörden und Organisationen mit Sicherheitsaufgaben (BOS), aber zunehmend auch die Einbeziehung der von der Krise betroffenen Akteure aus den Bereichen der Industrie und der Bürger, die eine Rolle als aktive Krisenmanager wahrnehmen und BOS unterstützen.

Die zunehmende Durchdringung der Lebenswelt mit IT macht auch nicht vor sicherheitskritischen Systemen halt. Anwendungsfelder betreffen kritische Infrastrukturen, Leitstellensysteme, Fahrzeug- und Verkehrsführungssoftware, Prozessführungssysteme, Produktionstechnologien, Anwendung der Medizintechnik, des Krisenmanagements, der Gefahrenabwehr oder des Terrorismus. Die Mensch-Computer-Interaktion in solchen sicherheitskritischen Systemen und Anwendungsfeldern ist eine Herausforderung nicht nur für die Informatik, sondern eine interdisziplinäre Aufgabe an der Schnittstelle vieler Disziplinen. Zunehmend müssen auch mobile Kontexte und Endgeräte sowie soziale Netzwerke in die Betrachtungen einbezogen werden.

[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

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.

More than 3 billion people use the Internet, many of whom also use social media services such as the social network Facebook with about 1.35 billion active users monthly or the microblogging platform Twitter numbering approximately 284 million active users monthly. This paper researches how a tailorable quality assessment service can assist the use of citizen-generated content from social media. In particular, we want to study how users can articulate their personal quality criteria appropriately. A presentation of related work is followed by an empirical study on the use of social media in the field of emergency management, focusing on situation assessment practices by the emergency services. Based on this, we present the tailorable quality assessment service (QAS) for social media content, which has been implemented and integrated into an existing application for both volunteers and the emergency services.

Die im Katastrophenschutz beteiligten Behörden und Organisationen mit Sicherheitsaufgaben (BOS) benötigen für Entscheidungen stets möglichst aktuelle und genaue Informationen. Diese werden dabei je nach Lage von den Einsatzkräften, welche sich am Schadensort befinden, via Funk an die teilweise entfernt sitzenden Entscheidungsträger berichtet. Unsere Design-Fallstudie untersucht interaktive Unterstützungsmöglichkeiten dieser Berichts- bzw. Reporting-Prozesse: In einer qualitativen empirischen Studie deckten wir die Kommunikationspraktiken von BOS auf und entwickelten darauf aufbauend ein Konzept zur semi-strukturierten Artikulation von Informationsbedarfen, welches als mobile Android Applikation implementiert und mit potentiellen Nutzern evaluiert wurde. Unser Beitrag präsentiert, wie zielgerichtete Anfragen von Informationen unter Berücksichtigung angemessener Metadaten das Berichts- und Meldewesen örtlich verteilter Einsatzkräfte unterstützen können.

End-User Development and Social Big Data – Towards Tailorable Situation Assessment with Social Media

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.

Mit zunehmender Zahl an Nutzern sozialer Medien steigt auch die Menge produzierter Datenmengen, welche häufig unter dem Schlagwort Big Social Data diskutiert werden. Um Informationen aus diesen großen Datenmengen generieren zu können, existiert aktuell bereits eine Vielzahl verschiedener Systeme, welche sich des Data Minings bedienen, um die Analyse zu erleichtern. Je nachdem für welche Fragestellung diese Datenmengen herangezogen werden sollen, kommen verschiedene Systeme in Frage, die jeweils ihre Stärken und Schwächen haben. Innerhalb dieses Beitrages geben wir eine Übersicht aktueller Systeme zur Analyse sozialer Medien im Generellen sowie im speziellen Kontext des Krisenmanagements. Auf Basis verschiedener Attribute wie der Möglichkeit zur Kommunikation, des Setzens eines Alarms oder der Tonalität sowie einer darauf basierenden Marktanalyse werden die Systeme in die drei Klassen Intelligence-, Management- und spezialisierten Analysesysteme klassifiziert und im Hinblick auf ihre Eignung für die Analyse sozialer Medien kategorisiert.

Social Haystack: Dynamic Quality Assessment of Citizen-Generated Content in Social Media during Emergencies
Ludwig Thomas, Reuter Christian, Pipek Volkmar
Acm transactions on computer-human interaction (tochi) 2015;21(4):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.

abstract = {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.},

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.

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′.

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.

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.

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.

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.

This workshop is aimed at bringing together a multidisciplinary group to discuss Machine Learning and its application in the workplace as a practical, everyday work matter. 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.

Appropriating 3D Printers in Augmented Reality
Jasche Florian, Ludwig Thomas
Proceedings of Mensch und Computer 2019: 2019 New York, NY, USA. . doi:10.1145/3340764.3345377

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.

Capitalizing Relationships: Modes of Participation in Crowdsourcing
Hansson Karin, Ludwig Thomas, Aitamurto Tanja

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.

A Practice-Oriented Paradigm for End-User Development
Ludwig Thomas, Dax Julian, Pipek Volkmar, Wulf Volker
In: Paternò Fabio, Wulf Volker: New Perspectives in End-User Development. Cham: Springer international publishing, 2017, 23–41. doi:10.1007/978-3-319-60291-2_2

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.

Work or leisure? Designing a user-centered approach for researching activity “in the wild”
Ludwig Thomas, Dax Julian, Pipek Volkmar, Randall Dave

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.
