Weber, P., Grönewald, L. & Ludwig, T. (2022)Reflection on the Octalysis framework as a design and evaluation tool

6th International GamiFIN Conference 2022 (GamiFIN 2022). Tampere, Finland, Pages: 75–84
[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.

Krauß, V., Jasche, F., Saßmannshausen, S. M., Ludwig, T. & Boden, A. (2021)Research and Practice Recommendations for Mixed Reality Design &\#x2013; Different Perspectives from the Community

Over the last decades, different kinds of design guides have been created to maintain consistency and usability in interactive system development. 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.

Hoffmann, S., Jasche, F. & Ludwig, T. (2021)Reflections on a Comparative AR Study

[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.

Nießner, J. & Ludwig, T. (2021)Design of a Knowledge-Based Recommender System for Recipes From an End-User Perspective

Nowadays, recommender systems are a fundamental part of several online services. However, most of these systems rely on collective user data and ratings or a preselection of parameters to derive appropriate recommendations. Within this paper, we examine recommendations without previous user data. We therefore designed and evaluated a knowledge-based recommender system by turning to recipe recommendations that offer alternatives for favorite recipes. We introduce and compare three versions of a given algorithm. Our evaluation shows that the knowledge-based approach may serve as a good start for deriving appropriate recommendations without prior user data. Moreover, we show that end-users’ assumptions about decisive criteria of a recommender system do not necessarily match the later actual decisive criteria.

In view of its capacity to create physical objects for a wide range of different potential applications, 3D printing has become increasingly popular over the years. However, given its scope of application, 3D printing can be challenging. Novice users often need assistance from experts, who are not always available. Recent interest in the development of conversational agents opens up the possibility of assisting novice users in their interactions with 3D printers, thus improving their experience. In this paper, we illustrate a potential concept of a conversational agent and present a prototype of a Telegram chatbot to improve the user experience of 3D printing.

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.

Jasche, F., Kirchhübel, J., Ludwig, T. & Tolmie, P. (2021)BeamLite: Diminishing Ecological Fractures of Remote Collaboration through Mixed Reality Environments

C&T ’21: Proceedings of the 10th International Conference on Communities & Technologies – Wicked Problems in the Age of Tech. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 200–211 doi:10.1145/3461564.3461566

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.

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.

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.

Jasche, F. & Ludwig, T. (2020)PrintARface: Supporting the Exploration of Cyber-Physical Systems through Augmented Reality

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.

Clarke, M. F., Gonzales, J., Harper, R., Randall, D., Ludwig, T. & Ikeya, N. (2019)Better Supporting Workers in ML Workplaces

Conference Companion Publication of the 2019 on Computer Supported Cooperative Work and Social Computing. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 443–448 doi:10.1145/3311957.3359429

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.

Jasche, F. & Ludwig, T. (2019)Appropriating 3D Printers in Augmented Reality

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.

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.

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.

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.

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.

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.

Reuter, C., Ludwig, T., Kaufhold, M. & Pipek, V. (2015)XHELP: Design of a Cross-Platform Social-Media Application to Support Volunteer Moderators in Disasters

[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.

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.

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.

Ludwig, T., Reuter, C., Heukäufer, R. & Pipek, V. (2015)CoTable : Collaborative Social Media Analysis with Multi-Touch Tables

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

Proceedings of the International Conference on Information and Communication Technologies for Disaster Management (ICT-DM). 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.

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.

Ludwig, T., Reuter, C., Siebigteroth, T. & Pipek, V. (2015)CrowdMonitor: Mobile Crowd Sensing for Assessing Physical and Digital Activities of Citizens during Emergencies

Proceedings of the International Conference on Human Factors in Computing Systems (CHI). New York, USA, Publisher: ACM Press, Pages: 4083–4092
[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.

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.

Over the last years, digital fabrication technologies such as 3D printers have become more and more common at universities and small businesses as well as in communities of hobbyist makers. The high complexity of such technologies, the rapid technological progress and the close link between hardware and software in this field poses challenges for users and communities learning how to operate these machines, especially in the contexts of existing (and changing) practices. We present an empirical study on the appropriation of 3D printers in two different communities and derive design implications and challenges for building appropriation infrastructures to help users face those challenges and making technologies more sociable.

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.

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.},

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 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.

[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.

[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.

Ludwig, T., Reuter, C. & Pipek, V. (2013)What You See Is What I Need: Mobile Reporting Practices in Emergencies

Proceedings of the European Conference on Computer Supported Cooperative Work (ECSCW). Paphos, Cyrus, Publisher: Springer, Pages: 181–206 doi:10.1007/978-1-4471-5346-7_10
[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.
