This paper presents the outcomes of an exploratory study focused on the evaluation of an interactive music exergame for People with Dementia (PwD) and their caregivers. PwD tend to isolate themselves from the outside world, therefore carers need to develop strategies to maintain communication with them. Studies indicate that music–based activities provide an effective way to achieve social interaction with PwD. At the same time, physical activity plays a major role in dementia-related interventions because it can slow down progression and provide meaningful stimulation. Our developed interactive music game bounds these two concerns together; we evaluated the system afterwards regarding its individual and social impact and its integration into the daily routines of both PwD and their caregivers, focusing on its capacity to provide both enjoyment and relief from some of the effects of dementia. Qualitative data collected over 4 months confirmed the valuable impact of music-based interventions of PwD. Of particular note was how PwD used the game to improve or maintain their physical condition while recovering past memories and an interest in social interaction.

The number of women in IT is still low and companies struggle to integrate female professionals. The aim of our research is to provide methodological support for understanding and sharing experiences of gendered practices in the IT industry and encouraging sustained reflection about these matters over time. We established a Living Lab with that end in view, aiming to enhance female participation in the IT workforce and committing ourselves to a participatory approach to the sharing of women’s experiences. Here, using the case of a German video game company which participated in our Lab, we detail our lessons learned. We show that this kind of long-term participation involves challenges over the lifetime of the project but can lead to substantial benefits for organizations. Our findings demonstrate that Living Labs are suitable for giving voice to marginalized groups, addressing their concerns and evoking change possibilities. Nevertheless, uncertainties about long-term sustainability remain.

A large portion of the software side of the global information technology infrastructure, including web search, email, social media, and much more, is in many cases provided free to the end users. At the same time, the corporations that provide these services are often enormously profitable. The business model that enables this involves customized advertising and sometimes behavior manipulation, powered by intensive gathering and cross-correlation of detailed personal information. These companies provide some great products and services at no upfront cost to the end users. But the model has a dark side as well, with negative impacts for privacy, autonomy, human dignity, and democracy. The purpose of this panel is to provide a civil forum for the CHI community as a whole to discuss this business model, including its advantages and disadvantages, and its impacts on CHI and HCI and society more generally, with an eye toward responsible innovation.

Bossauer, P., Neifer, T., Stevens, G. & Pakusch, C. (2020)Trust versus Privacy: Using Connected Car Data in Peer-to-Peer Carsharing

Trust is the lubricant of the sharing economy. This is true especially in peer-to-peer carsharing, in which one leaves a highly valuable good to a stranger in the hope of getting it back unscathed. Nowadays, ratings of other users are major mechanisms for establishing trust. To foster uptake of peer-to-peer carsharing, connected car technology opens new possibilities to support trust-building, e.g., by adding driving behavior statistics to users‘ profiles. However, collecting such data intrudes into rentees‘ privacy. To explore the tension between the need for trust and privacy demands, we conducted three focus group and eight individual interviews. Our results show that connected car technologies can increase trust for car owners and rentees not only before but also during and after rentals. The design of such systems must allow a differentiation between information in terms of type, the context, and the negotiability of information disclosure.

Ageing societies and the associated pressure on the care systems are major drivers for new developments in socially assistive robotics. To understand better the real-world potential of robot-based assistance, we undertook a 10-week case study in a care home involving groups of residents, caregivers and managers as stakeholders. We identified both, enablers and barriers to the potential implementation of robot systems. The study employed the robot platform Pepper, which was deployed with a view to understanding better multi-domain interventions with a robot supporting physical activation, cognitive training and social facilitation. We employed the robot in a group setting in a care facility over the course of 10 weeks and 20 sessions, observing how stakeholders, including residents and caregivers, appropriated, adapted to, and perceived the robot. We also conducted interviews with 11 residents and caregivers. Our results indicate that the residents were positively engaged in the training sessions that were moderated by the robot. The study revealed that such humanoid robots can work in a care home but that there is a moderating person needed, that is in control of the robot.

Unbehaun, D., Aal, K., Vaziri, D. D., Tolmie, P. D., Wieching, R., Randall, D. & Wulf, V. (2020)Social Technology Appropriation in Dementia: Investigating the Role of Caregivers in Engaging People with Dementia with a Videogame-based Training System

There has been increasing interest in designing for dementia in recent years. Empirical investigation is now needed of the long-term role of caregivers in appropriating ICTs into the complex daily life of people with dementia (PwD). We present here the outcomes of a 4-month evaluation of the individual, social and institutional impact of a videogame-based training system. The everyday behavior and interactions of 52 PwD and 25 caregivers was studied qualitatively, focusing on the role played by caregivers in integrating the system into daily routines. Our results indicate that the successful appropriation of ICT for PwD depends partly on the physical, cognitive and social benefits for PwD, but especially on the added value perceived by their social care-network. We discuss the need for design in dementia to develop more socially embedded innovations that can address the social actors involved and thus contribute to practical solutions for professional and private care.

Currently, there is a broad range of studies dealing with the design and visualization of energy consumption data for the domestic and increasingly for the office context. However, studies addressing the industrial context are quite rare, and due to the diversity of machines, processes, tasks, personal motivations, teams and the specific organizational culture of companies, it is not sufficient to provide only consumption data. For an adequate consideration of these factors, detailed design guidelines and system concepts are currently missing. However, this study shows the potential that a common understanding of consumption data can emerge through suitable visualization to support everyday work and possibilities of data sharing. Therefore, we show exemplarily how a design can be derived from empirically collected requirements and how a system concept can look like that enrich current eco-feedback design research for the industrial context.

Studying armed political struggles from a CSCW perspective can throw the complex interactions between culture, technology, materiality and political conflict into sharp relief. Such studies highlight interrelations that otherwise remain under-remarked upon, despite their severe consequences. The present paper provides an account of the armed struggle of one of the Colombian guerrillas, FARC-EP, with the Colombian army. We document how radio-based communication became a crucial, but ambiguous infrastructure of war. The sudden introduction of localization technologies by the Colombian army presented a lethal threat to the guerrilla group. Our interviewees report a severe learning process to diminish this new risk, relying on a combination of informed beliefs and significant technical understanding. We end with a discussion of the role of HCI in considerations of ICT use in armed conflicts and introduce the concept of counter-appropriation as process of adapting one’s practices to other’s appropriation of technology in conflict.

Since the terrorist attacks of 9/11, the use of social media in emergency and crisis events has greatly increased and many studies have concentrated on the use of ICT and social media be-fore, during or after these events. The field of research that these studies fall under is called cri-sis informatics. In this paper, we evaluate and analyze crisis informatics research by looking at case studies of social media use in emergencies, outlining the types of research found in crisis informatics, and expounding upon the forms of interaction that have been researched. Finally, we summarize the achievements from an HCI perspective and outline trends and challenges for future research.

Social media has been established in many larger emergencies and crises. This process has not started just a few years ago, but already 15 years ago in 2001 after the terrorist attacks of 9/11. In the following years, especially in the last 10, sometimes summarized under the term crisis informatics, a variety of studies focusing on the use of ICT and social media before, during or after nearly every crisis and emergency has arisen. This article aims to recapitulate 15 years of social media in emergencies and its research with a special emphasis on use patterns, role patterns and perception patterns that can be found across different cases in order to point out what has been achieved so far, and what future potentials exist.

Castelli, N., Ogonowski, C., Jakobi, T., Stein, M., Stevens, G. & Wulf, V. (2017)What happened in my home?: An End-User Development Approach for Smart Home Data Visualization

Proceedings of the Conference on Human Factors in Computing Systems (CHI).
[BibTeX] [Abstract]

Smart home systems change the way we experience the home. While there are established research fields within HCI for visualizing specific use cases of a smart home, studies targeting user demands on visualizations spanning across multiple use cases are rare. Especially, individual data-related demands pose a challenge for usable visualizations. To investigate potentials of an end-user development (EUD) approach for flexibly supporting such demands, we developed a smart home system featuring both pre-defined visualizations and a visualization creation tool. To evaluate our concept, we installed our prototype in 12 households as part of a Living Lab study. Results are based on three interview studies, a design workshop and system log data. We identified eight overarching interests in home data and show how participants used pre-defined visualizations to get an overview and the creation tool to not only address specific use cases but also to answer questions by creating temporary visualizations.

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.

In recent years, social media have increased the resources that individuals and organizations are able to mobilize for the development of socially innovative practices. In this article, we engage with a naturally occurring development in a Trentinian neighbourhood to examine the cooperative interactions amongst members of a local community. The first author and local residents of the neighbourhood participated in online discussions, decision making, and physical activities that led to material changes in the area. The interventions are motivated by and based on the concept of Social Street that combines online interactions in a closed Facebook group with face-to-face meetings seeking to practically engage the collective in accomplishing certain immediate or ongoing needs. Over the course of two years, we studied this local instantiation of Social Street in Trento, Italy by way of an action-oriented (digital) ethnography. Through this work, we demonstrate how urban neighbourhoods might benefit from hybrid forms of community engagement that are enacted through a constant back and forth between online and face-to-face interactions. We further argue that the infrastructuring of local urban collectives should follow strategies that pay attention to the multiple issues in urban neighbourhoods and people’s attachments to them. Overall, the paper reflects upon the challenges and configurations of participation that this form of community-work entails.

Reuter, C., Kaufhold, M., Leopold, I. & Knipp, H. (2017)Katwarn, NINA or FEMA? Multi-Method Study on Distribution, Use and Public Views on Crisis Apps

European Conference on Information Systems (ECIS). Guimarães, Portugal, Publisher: AIS, Pages: 2187–2201
[BibTeX] [Abstract] [Download PDF]

Crises, such as thunderstorms and an increasing number of (recognised) terroristic attacks in 2015, 2016, and 2017, do not only lead to extensive monetary damage, but also threaten human lives and influence citizens‘ perceptions of safety and security. In such situations, the population demands information about the damage and safe behaviour. Although some apps are available to provide this information, the number of users seems relatively low. Focussing on Germany, this study aims to research (1) the distribution of crisis apps in the population, (2) the kinds of crisis apps currently used, as well as (3) needed core functionalities of warning apps. This multi-method study analyses crisis apps by investigating their utilisation quantitatively in a snowball-based survey in Europe (n=1,034) and in a representative survey in Germany (n=1,369). Based on this, the German warning apps Katwarn and NINA and the US-American app FEMA are evaluated qualitatively (n=22). The results revealed requirements which informed the implementation of a warning app prototype. The prototype combines the identified advantages of the apps evaluated in the study, containing warnings and all-clear, recommendations for action, functions to contact friends and helpers. The contributions of this work are findings on the distribution of crisis apps in Europe and Germany (both 16\%), the kinds of crisis apps used (mostly weather and warning apps), and empirically based requirements for warning apps which can be integrated in further developments of existing apps and a prototype for such an app.

This multi-method study analyses crisis apps by investigating their utilisation quantitatively in a snowball-based survey in Europe (n=1,034) and in a representative survey in Germany (n=1,369). Based on this, the German warning apps Katwarn and NINA and the US-American app FEMA are evaluated qualitatively (n=22). The results revealed requirements which informed the implementation of a warning app prototype. The prototype combines the identified advantages of the apps evaluated in the study, containing warnings and all-clear, recommendations for action, functions to contact friends and helpers. The contributions of this work are findings on the distribution of crisis apps in Europe and Germany (both 16\%), the kinds of crisis apps used (mostly weather and warning apps), and empirically based requirements for warning apps which can be integrated in further developments of existing apps and a prototype for such an app.},

The value of social media in crises, disasters, and emergencies across different events (e.g. floods, storms, terroristic attacks), countries, and for heterogeneous participants (e.g. citizens, emergency services) is now well-attested. Existing work has examined the potentials and weaknesses of its use during specific events. Fewer studies, however, have focused on citizens‘ perceptions of social media in emergencies, and none have deployed a representative sample to examine this. We present the results of the first representative study on citizens‘ perception of social media in emergencies that we have conducted in Germany. Our study highlights, for example, that around half (45\%) of people have used social media during an emergency to share and / or look for information. In contrast, false rumours on social media (74\%) are perceived as a threat. Moreover, only a minority of people have downloaded a smartphone app for emergencies (16\%), with the most popular ones‘ weather and first aid apps.

Social media is increasingly being used during emergencies. Most available studies are focused on how citizens and/or authorities use these technologies in concrete events. However, larger quantitative studies with significant results on attitudes, needs and future plans of citizens in such events are not available – especially such of a comparative nature related to emergency services. As part of the EU project ‘EmerGent‘ this article presents the findings of a survey of 1034 citizens across 30 European countries conducted between February and June 2015 to explore citizens‘ attitudes towards the use of social media for private purposes and in emergency situations. The article briefly compares these findings with a second survey conducted with 761 emergency service staff across 32 European countries from September to December 2014. The aim of the overall study is to discuss citizens‘ attitudes towards social media in emergencies in order to derive challenges and opportunities for social resilience.

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.

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.

Living Labs provide a human-centric‘ research approach for the design of new ICT artefacts. In Living Labs users participate over several design stages, providing insights into unexpected ICT use, co-creation and evaluation of new IT solutions. Although this approach is becoming more popular, there is little comparative and reflective work on its practical dynamics, problems and possibilities. In this study, we analyse two 4-year Living Lab projects in Lancaster, UK and Siegen, Germany within the domain of Social TV, and compare experiences. We focus on documenting the purposes, methods and user dynamics that affect the trajectory of such long-term research initiatives, focusing inter alia on the dynamics of researcher/user interaction and the developing issues of trust and managing expectations; emphasizing some often neglected ethical issues and the impact of users‘ individual characteristics and their role in the community dynamics of Living Labs.

Yerousis, G., Aal, K., von Rekowski, T., Randall, D., Rohde, M. & Wulf, V. (2015)Computer-Enabled Project Spaces: Connecting with Palestinian Refugees across Camp Boundaries

Proceedings of the ACM Conference on Human Factors in Computing Systems – CHI ’15. New York, New York, USA, Publisher: ACM Press, Pages: 3749–3758 doi:10.1145/2702123.2702283

Come_IN computer clubs are an established approach to support inter-cultural and inter-generational learning in German neighborhoods. We explore the adaptation of the come_IN concept to the Palestinian context as a means to bridge the social and economic divide that has plagued West Bank society for a period of more than six decades. Social exclusion, political conflicts and prolonged military occupation have kept the refugee camps in a perpetual state of marginalization. In this paper we report on our work in Al Amari – a Palestinian refugee camp adjacent to the city of Ramallah. We examine how the computer club enables the emergence of social ties among residents of the camp and university students acting as tutors. Even though the ties are small-scale and informal, they have the potential to generate new and wider opportunities for exchange that may eventually support more social integration between the camp’s marginalized population and the wider Palestinian population.

abstract = {Come\_IN computer clubs are an established approach to support inter-cultural and inter-generational learning in German neighborhoods. We explore the adaptation of the come\_IN concept to the Palestinian context as a means to bridge the social and economic divide that has plagued West Bank society for a period of more than six decades. Social exclusion, political conflicts and prolonged military occupation have kept the refugee camps in a perpetual state of marginalization. In this paper we report on our work in Al Amari – a Palestinian refugee camp adjacent to the city of Ramallah. We examine how the computer club enables the emergence of social ties among residents of the camp and university students acting as tutors. Even though the ties are small-scale and informal, they have the potential to generate new and wider opportunities for exchange that may eventually support more social integration between the camp's marginalized population and the wider Palestinian population.},

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.

Müller, C., Hornung, D., Hamm, T. & Wulf, V. (2015)Practice – based Design of a Neighborhood Portal : Focusing on Elderly Tenants in a City Quarter Living Lab

IN Proceedings of the International Conference on Human Factors in Computing Systems (CHI), Pages: 2295–2304 doi:10.1145/2702123.2702449
[BibTeX] [Abstract]

This paper contributes to the current discourse on practicebased research in HCI paying particular attention to the overall temporal and situational conditions which frame an R&D project. We present a Living Lab study situated in an arbitrary neighborhood of a German city which develops ICT support to foster informal help and social interaction with a special, but not exclusive, focus on elderly tenants. We demonstrate that practice-based, long-term research in a city quarter goes beyond those challenges already described in the current Living Lab and PD literature. The long-term study’s positioning in a real-world context is contoured not only by a high diversity of stakeholders and their individual interests and motivation for participation but also by their individual skill sets and learning needs. These distinct and often contradictive perspectives have to be permanently counterbalanced. Thus attention has to be focused on how related strategies and decisions impact on the design of the project as well as on the final ICT product. To enable all tenants, irrespective of age and technical skill, to participate in a long-term ICT-based community development project, we applied the format of ‘experience-based PD workshops‘ to foster confidence in ICT usage and encourage the competency of the elderly and non-tech-savvy tenants.

[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.

Ludwig, T., Reuter, C. & Pipek, V. (2015)Social Haystack: Dynamic Quality Assessment of Citizen-Generated Content in Social Media during Emergencies

[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.

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.

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.

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.},

We analyze practices of political activists in a Palestinian village located in the West Bank, who organize weekly demonstrations against Israel’s settlement policy and the separation wall. Over a period of 28 months, we conducted a field study consisting of eight days ‘on the ground‘ observation and interviewing, and extensive monitoring of Internet communication. We describe the activists‘ background and their efforts to organize these demonstrations under conditions of military occupation. Over time, we observe the role both digital and material factors play in the organization of protest.

This paper presents results of a three-year research project focused on the emplacement of Home Energy Management Systems (HEMS) in a living lab setting with seven households. The HEMS used in this study allowed householders to monitor energy consumption both in realtime and in retrospective on the TV and on mobile devices. Contrasting with existing research focused on how technology persuades people to consume less energy, our study uses a grounded approach to analyze HEMS emplacement. As an important result, we present here the issue of ‚energy literacy‘. Our study reveals that, by using HEMS, participants became increasingly literate in understanding domestic electricity consumption. We discuss the role HEMS played in that process and how the acquired literacy changed energy consumption patterns. We conclude that literacy in energy consumption has value on its own and explain how eco feedback system designs can benefit from this understanding. Copyright © 2013 ACM.

In diesem Beitrag werden Studien zu ‚virtuellen‘ und ‚realen‘ Selbsthilfeaktivitäten dargestellt. Untersucht wurden zum einen ‚virtuelle‘ Selbsthilfeaktivitäten in Twitter während der Tornadokatastrophe in den USA am 27./28.4.2011 mit besonderem Fokus auf die zeitlichen Verläufe und Nutzergruppen; zum anderen ‚reale‘ Selbsthilfe anhand Interviews mit Behörden und Organisationen mit Sicherheitsaufgaben (BOS). Hierauf aufbauend werden Gestaltungsaspekte und Anforderungen für Social Media zur Unterstützung von Krisenhelfern bzw. Selbst- und Nachbarschafts- hilfe und zur Kombination von virtuellen und realen Aktivitäten im Katastrophenmanagement diskutiert.

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.

Adaptations of business processes are important in work environments, specifically when process-support needs to be tailored according to changing needs. The creation, management, and adaptation of the process models require typically modeling-experts. While these actors are knowledgeable in formalizing and operationalizing processes end-users who do not necessarily possess sophisticated modeling skills know typically local practices and framing conditions best. In this paper, we present an approach to support users in articulating their needs and to involve them into the (re-)design of process specifications. We explore how end-users reflect upon and articulate about business processes. Based on results of a qualitative study, we present a new, paper-based interaction technique, which enables users with little skills to model processes. The resulting process specifications can be transferred either in paper or in digital form into traditional modeling systems for further elaboration.

Improvisation is necessary when planned decision-making as the main managerial activity does not fit the conditions the practice provides. In these cases, information technology should not just automate planned and structured decisions, but support improvisational practice. In this contribution we present an empirical study about the improvisation work in scenarios of medium to large power outages in Germany. Our focus is on inter-organizational cooperation practices, thus we examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material allows to describe reasons and conditions for improvisation. Our resulting recommendations address the support of aggregation and visualization of information, a necessary individualization of information compositions, options for collaborative situation assessment, requirements for informal and formal communication, and accessibility of information resources.

Yetim, F. (2011)Bringing discourse ethics to Value Sensitive Design: Pathways toward a deliberative future

IN AIS Transactions on Human-Computer Interaction, Vol. 3, Pages: 133–155
[BibTeX] [Abstract]

Value Sensitive Design (VSD) is a comprehensive framework for advancing a value-centered research and design agenda. It provides methods for producing and evaluating a design outcome by taking human values into account. Drawing on discourse ethics, this paper first critically analyzes the status quo in VSD and identifies some gaps. These mainly concern the lack of explicit methods for supporting a deliberative and legitimate process of decision making with respect to many concerns, including the identification of stakeholders, the legitimation of common design communication, the justification of trade-offs and/or a common regulation in case of competing or incommensurable values, as well as the deliberativeness of other design decisions such as the selection of design goals and means. In addition, this paper suggests ways to move VSD toward the standards of discourse ethics by drawing on the knowledge base of critical research in the Information Systems field. In particular, the suggestions concern the inclusion of a practical method for boundary critique and different types of discourses and principles as well as discourse support methods and tools for structuring participation in a way that allows participants to deal with the plurality of values, norms, goals and means deliberatively. Finally, this paper revisits a VSD case and explores the applicability of the ideas suggested.

[BibTeX] [Abstract]

News reports of Internet-based security breaches, identity theft, fraud, and other dangers may increase the perceived risk and decrease the perceived benefits of using electronic services (or e-services). We examine whether interactivity serves as a means to diminish the perceived risks and increase the perceived benefits of using e-services. To examine interactivity‟s influence on consumers‟ perceptions, we conducted a laboratory experiment using a simulated web-based, online payment system. When compared to a non-interactive preview of an online payment system, we found that consumers who used an interactive e-service simulation reported higher perceived involvement and authenticity as well as higher intangibility and risks of e-services. Further, we found that interactivity moderated relationships such that consumers were more likely to report higher intentions to use e- services. The paper concludes with implications for research and practice

Located in socially and culturally diverse neighborhoods, we have built a network of intercultural computer clubs, called come-IN. These clubs offer a place to share practices among children and adults of diverse ethnical backgrounds. We show how this initiative ties into the striving for the integration of migrant communities and host society in Germany. In this paper, we analyze how collaborative project work and the use of mobile media and technologies contribute to integration processes in multicultural neighborhoods. Qualitative data gathered from interviews with club participants, participative observation in the computer clubs, as well as the analysis of artifacts created during project work provides the background needed to match local needs and peculiarities with (mobile) technologies. Based on these findings we present two approaches to add to the technological infrastructure: (1) a mesh-network extending the clubs into the neighborhood and (2) a project management tool, which supports projects and stimulates the sharing of ideas among projects. © 2011 Elsevier Ltd.

Values play a significant role in Information Systems Development (ISD). This paper presents a critical analysis of three methodological frameworks which aim at systematically considering values in the development of systems. The analysis focuses on their main goals, value concepts, and activities. In addition, this paper discusses some challenges and controversial issues with respect to the design for values and suggests an agenda for future research.

Expert recommender systems (ERS) are considered a promising technology in knowledge management. However, there are very few studies which evaluated their appropriation in practice. In this paper, we present results of a case study of expert recommender technology in a large European industrial association. Unlike existing expert recommender approaches, the system involves users in selecting textual documents for semi-automatic profile generation. Our study focuses on the appropriation of this functionality and discusses impacts from an organizational perspective.

Ramirez, L., Denef, S. & Dyrks, T. (2009)Towards human-centered support for indoor navigation

IN Proceedings of the Conference on Human Factors in Computing Systems (CHI), Pages: 1279–1282 doi:10.1145/1518701.1518893
[BibTeX] [Abstract]

This paper presents a new perspective for the design of indoor navigation support. In contrast to technology oriented approaches coming from Context Awareness research, we argue for a wider focus that complements the technical question of providing precise indoor location with the development of more effective navigation practices based on technology available today. Starting from research on indoor navigation conducted with the Paris Fire Brigade, we present two design concepts aimed at supporting firefighters in creating and finding their own paths, together with some of the design strategies that informed the creation of these concepts.

IN Journal of Information Technology, Vol. 21, Pages: 40–51 doi:10.1057/palgrave.jit.2000053
[BibTeX] [Abstract]

Ignoring the informal, non-canonical nature of knowledge sharing, including people’s motivation, ability and opportunity to share knowledge, is one of the key causes of resistance to use knowledge-sharing tools. In order to improve knowledge sharing supported by information technology (IT), tools need to be embedded in the social networks of which it is part. This has implications for our knowledge on the design requirements of such socially embedded IT. The paper reviews tools that are designed for the purpose to foster social capital. We will then discuss what is needed for an IS design theory related to knowledge communities and how such a theory could incorporate social capital theory.Journal of Information Technology (2006) 21, 40–51. doi:10.1057/palgrave.jit.2000053 Published online 4 October 2005

IN Wirtschaftsinformatik, Vol. 42, Pages: 318–328
[BibTeX] [Abstract]

Zugriffskontrollsysteme für kooperative Arbeitsumgebungen zeichnen sich durch eine hohe Komplexität aus. Das führt zu Schwierigkeiten bei der Präsentation und Manipulation von Zugriffskontrollsystemen auf der Ebene der Benutzerschnittstelle. Das Problem wird zudem durch die in kooperativen Arbeitsumgebungen vorherrschende starke Dynamik verschärft. Dieser Beitrag stellt einen nutzerorientierten Ansatz vor, dessen grundlegendes Konzept auf Zugriffsregeln basiert. Das Konzept, bei dem Erlaubnisse oder auch Verbote durch Zugriffsregeln repräsentiert werden, wurde auf Basis einer Feldstudie entwickelt. Die Regeln haben einen Gültigkeitsbereich, der durch Faktoren wie Benutzer, Dokumente, Rollen und Zeitintervalle definiert wird. Wir beschreiben, wie dieser Ansatz implementiert und in einem kommerziellen Groupware-System integriert wurde. Abschließend werden die Resultate einer Evaluation des Prototypen auf Basis der thinking-aloud-Methode diskutiert.
