  Grinko, M., Ertl, T., Aal, K. & Wulf, V. (2021)Transitions by Methodology in Human-Wildlife Conflict – Reflections on Tech-based Reorganization of Social Practices

  LIMITS ’21: Workshop on Computing within Limits., Pages: 13
  [BibTeX] [Abstract]

  Can cattle farmers live peacefully alongside lions, and what role can technology play in this sensitive setting? Since 2017, we have been investigating this question in the Okavango Delta, Botswana, using a Grounded Design (GD) approach. Based on community involvement we have been building and evaluating a system together with local and foreign experts which warns the locals when a lion comes near their village or their cattle and which has significantly reduced livestock predation by giving time for action. However, as our research shows, technology alone is not the solution for locals’ problems: education, knowledge transfer, economic self-determination, as well as the revival of herding traditions and lost connection to nature need to evolve further to foster a true coexistence between humans and predators in Botswana – and perhaps all over the world. To address these problems and solutions by design and ensure sustainability of its outcome, it is important to take into account the oral culture and collective history of the inhabitants with predators, especially lions. Consideration must also be given to their social environment and individual experiences and goals, as well as their digital infrastructure, accessibility, and digital ecologies. We therefore argue that the successful development of a design solution requires a holistic understanding of design that is built on inclusion, participation, collaboration, understanding, respect, sacredness and the always-recurrent cyclic renovation of life.

  Ertl, T., Müller, C., Aal, K., Wulf, V., Tachtler, F., Scheepmaker, L., Fitzpatrick, G., Smith, N. & Schuler, D. (2021)Ethical Future Environments: Smart Thinking about Smart Cities means engaging with its Most Vulnerable

  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: 340–345 doi:10.1145/3461564.3468165

  Over the past several decades the concept of smart cities has gained a lot of attention amongst researchers, the media, governments, civic groups and citizens. The literature shows that innovations have a more positive impact when they stimulate the development of cities and shape their space for a variety of participants, or when design is participatory. This ensures a non-technocratic approach, i.e., one that builds on the complexity of today’s socio-technical systems and the consideration of their individual actors. Citizen-based approaches or one of the so-called Caring Community are possible answers to this. In this Design Fiction workshop, we take a critical view on the idea of smart cities by broadening participation to stakeholders who are still excluded from its concept and can be described as vulnerable and often marginalized, such as people who are (culturally) diverse (e.g. migrants, refugees, older adults, children, currently and formerly incarcerated people, homeless people and those with low income) or neurodiverse (e.g. people living with mental health challenges as autism or dementia or who suffer from functional impairments), and also animals and nature who are left behind in the whole digitization process. In this regard we will also address topics like sustainability and well-being. One of the expected outcomes of this workshop is the development of a holistic and sustainable smart city concept involving currently excluded stakeholders.

  There has been increasing interest in socially just use of Artificial Intelligence (AI) and Machine Learning (ML) in the development of technology that may be extended to marginalized people. However, the exploration of such technologies entails the development of an understanding of how they may increase and/or counter marginalization. The use of AI/ML algorithms can lead to several challenges, such as privacy and security concerns, biases, unfairness, and lack of cultural awareness, which especially affect marginalized people. This workshop will provide a forum to share experiences and challenges of developing AI/ML health and social wellbeing technologies with/for marginalized people and will work towards developing design methods to engage in the re-envisioning of AI/ML technologies for and with marginalized people. In doing so we will create cross-research area dialogues and collaborations. These discussions build a basis to (1) explore potential tools to support designing AI/ML systems with marginalized people, and (2) develop a design agenda for future research and AI/ML technology for and with marginalized people.

  With this Provocation, we aim at starting a dialogue between researchers who struggle with applying qualitative and ethnographic methods and following approaches in non-Western settings. Going by the book might not be an option when conducting research in politically charged or un-stable regions. Local politics, social pressure and even people’s personal safety are aspects that require consideration. Based on our experience from conducting fieldwork in Morocco, Palestine and Botswana, we reflect upon the difficulties we came across. We argue that, messiness, to some extent comes naturally with immersive fieldwork. On the other hand, in order to find ‚clean‘ ways of conducting ethnographic fieldwork in non-Western contexts, novel forms of (applying) methods are needed. By providing questions regarding three different aspects (applying methods on the Ground, Ethics, and Participation) we encourage researchers to reflect upon their own experiences.

  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.

  Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–15 doi:10.1145/3313831.3376648

  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.

  [BibTeX] [Abstract] [Download PDF]

  Information and Communication Technology (ICT) has penetrated almost all areas of life today and has the potential to create positive change. This paper addresses the opportunities offered by ICT for improving the resilience and psychosocial well-being of refugees who have experienced mentally stressful events when forced to leave their home country and seek shelter in a different host country. We want to distinguish between perceived stress and clinically-defined trauma, for which therapeutic interventions require direct personal contact with psychological experts. However, we also want to focus on the digital possibilities that currently exist to support establishing this kind of personal connection. Many refugees need to seek psychological help, but social, economic and cultural barriers hold them back. Our qualitative study with refugees, psychologists and volunteers provides insights into how refugees deal with their mental issues and the challenges they face in everyday life. We aim to show that ICT can play a major role in terms of addressing awareness and self-empowerment as an entry point for this vulnerable group. We also discuss the potential challenges and benefits of ICT for refugees seeking to recover their mental stability.

  As a result of aging societies, the prevalence of dementia, and accordingly the need for care is increasing. The use of information and communication (ICT)-based technologies may facilitate and promote a self-sustaining lifestyle for people with dementia and their caregivers. In this article, the authors provide results from a design study of an ICT-based system to support activity and mobility for people with dementia and their care-network. The authors investigated practices, attitudes and the social contexts of 26 people with dementia and their caregivers and designed an ICT-based prototype system that was evaluated afterwards in a four-month evaluation study. Here, the goal was to assess usability, user experience and acceptance and to analyze the effects of system usage on physical, cognitive and socio-emotional conditions of people with dementia and their caregivers. Our results indicate that the system supports people with dementia and their related caregivers partly during their social and daily activities and improves their quality of life. Furthermore, results suggest that motivation, collaboration and cooperation among the parties involved were increased by using the system. Integration and social embeddedness of ICT-based systems into the daily lives of people is the key for long-term and sustainable use. However, the involvement of caregivers and stakeholders seems to be an additional facilitating factor for daily life integration and may promote long-term use.

  CHI EA ’21: Extended Abstracts of the 2021 CHI Conference on Human Factors in Computing Systems. New York, NY, United States, Publisher: Association for Computing Machinery, Pages: 1–5 doi:10.1145/3411763.3441328

  There are several frameworks and approaches, addressing how to conduct ethnographic and qualitative field work in various settings. However, going by the book might not be an option when conducting research in politically charged, unstable or simply non-western regions. Politics, social pressure and even someone’s personal safety might be necessary to consider. Another important area to consider are research ethics. Privacy policies might do their work with regard to existing laws which differ from each country and should ensure no harm for all involved parties, but how can this be guaranteed and does it also cover all aspects of ethics? Including stakeholders as a basis for user-centered work and design is common. But what does participation mean in such contexts? The questions are: What is important to consider when conducting ethnographic field work in such settings? How can we foster different degrees of genuine participation? How can we ensure, that the work we do is ethically correct without endangering the research outcome? In this workshop, we invite researchers and practitioners to rethink existing methods and approaches and start working on guidelines, that better serves the needs of such specific and to some extent critical circumstances.

  Ertl, T., Taugerbeck, S., Esau, M., Aal, K., Tolmie, P. & Wulf, V. (2019)The Social Mile – How (Psychosocial) ICT can Help to Promote Resocialization and to Overcome Prison

  IN Proceedings of the ACM on Human-Computer Interaction, Vol. 3, Pages: 248:1–248:31 doi:10.1145/3370270
  [BibTeX] [Abstract] [Download PDF]

  There is currently uncertainty in the research community as to how ICT can and should be designed in such a way that it can be convincingly integrated into the everyday lives of prison inmates. In this paper, we discuss a design fiction that closes this research gap. The descriptions and results of the study are purely fictitious. Excluded is the State of the Art as well as the description of the legal situation of prisons in Germany. The analysis of the fictional study data designed here thus refers to the real world in order to derive ethical guidelines and draw practical conclusions. It is our intention to use these results as a possible basis for further research. The paper presents results of an explorative study dealing with the design, development and evaluation of an AI-based Smart Mirror System, Prison AI 2.0, in a German prison. Prison AI 2.0 was developed for daily use and voluntarily tested by eight prisoners over a period of 12 months to gain insight into their individual and social impact, with an emphasis on its ability to actively support rehabilitation. Based on qualitative data, our findings suggest that intelligent AI-based devices can actually help promote such an outcome. Our results also confirm the valuable impact of (Psychosocial) ICT on the psychological, social and individual aspects of prison life, and in particular how prisoners used the Smart Mirror system to improve and maintain their cognitive, mental and physical state and to restore social interactions with the outside world. With the presentation of these results we want to initiate discussions about the use of ICT by prisoners in closed prisons in order to identify opportunities and risks.

  Taugerbeck, S., Ahmadi, M., Schorch, M., Unbehaun, D., Aal, K. & Wulf, V. (2019)Digital Participation in Prison – A Public Discourse Analysis of the Use of ICT by Inmates

  [BibTeX] [Abstract] [Download PDF]

  Digital participation has become an important issue in modern societies, typically focusing on groups prone to marginalization. From this perspective, less attention has yet been paid to imprisoned persons. Many penitentiary systems are formally characterized by the basic requirement of resocialization. Accordingly, life in prison should be largely adapted to conditions outside and to fundamental social changes, which must be considered in designing the framework for prison systems. Still, the digital opening of the prison is debated controversially, not least due to anticipated security issues. Hence, to raise awareness about challenges for digital participation of prisoners, we conducted a knowledge-sociological analysis (SKAD) of the public discourse on the use of ICT by prison inmates in Germany. We thereby seek to advance knowledge and insights from social and organizational practice arising from the use of ICT in context of total institutions and create the basis for action from a socio-informatics perspective.

  [BibTeX] [Abstract] [Download PDF]

  For migrants and refugees, settling in a host country often proves hugely problematic. The ability to communicate marks a significant step in the process of resettlement. The current high number of migrants coming to Europe has therefore meant that the need to improve and increase the availability of language provision has become more pressing. Nevertheless, due to the complexity of financial and legal regulations and of policy restrictions, access to and information about available courses are in practice hard to find, and non-funded volunteer initiatives are scarcely visible at all. To address this problem, a newly developed language-course wizard provides orientation for refugees and migrants. Findings indicate that its visual representation is apt to span a broad range of cultural as well as educational backgrounds. Our work demonstrates the need for a detailed approach to understanding the challenges that refugees and other migrants face in practice. Failing this, services frequently do not reach those they are intended for.

  This case study describes the establishment of an educational ICT-intervention, a Computer Club, in the High Atlas, Morocco. We will first give an overview of the general approach and the first intervention. Then, we go into depth of the following trip, 15 months after the opening of the Computer Club. We describe the concerns to address and activities planned in advance based on the knowledge we acquired during the first intervention as well as on the insights we gained during this trip and discuss how much has changed. Reflections of these experiences discuss the importance of involving local partners, mitigating the power dynamics to build a trustful relationship and the impact of the intervention on the valley. We conclude with the most recent developments which involved a visit of the local partners to Germany to create a common understanding of the club approach.

  Not only today, but also in the future information technology and the advances in the field of computer science will have a high relevance for peace and security. Naturally, a textbook like this can only cover a selective part of research and a certain point in time. Nonetheless, it can be attempted to identify trends, challenges and venture an outlook into the future. That is exactly what we want to achieve in this chapter: To predict future developments and try to classify them correctly. These considerations were made both by the editor and the authors involved alike. Therefore, an outlook based on fundamentals, cyber conflicts and war, cyber peace, cyber arms control, infrastructures as well as social interaction is given.

  Social media as well as information and communication technology (ICT) play a major role in different conflicts all over the world. They have been crucial tools in the beginning of the so-called `Arab Spring‘ in Tunisia, the ongoing war in Syria, the struggle of Palestinian activists but also the Ukraine-Russia conflict. In this work, we provide the readers with an overview of current state of affairs regarding the use of ICTs in general and social media in particular in conflicts. Afterwards, we discuss how and what kind of tools and methods different actors use in their struggle. We especially focus on how actors appropriate the available tools to suit the specific conditions they find themselves in, such as risks of online surveillance, danger of prosecution of themselves or close others and varying levels of connectivity. We finally discuss the importance of an embedded perspective on the use of ICTs in conflict to understand these practices of appropriation.

  Weise, F. J., Hauptmeier, H., Stratford, K. J., Hayward, M. W., Aal, K., Heuer, M., Tomeletso, M., Wulf, V., Somers, M. J. & Stein, A. B. (2019)Lions at the Gates: Trans-disciplinary Design of an Early Warning System to Improve Human-Lion Coexistence

  IN Frontiers in Ecology and Evolution, Vol. 6 doi:10.3389/fevo.2018.00242
  [BibTeX] [Abstract] [Download PDF]

  Across Africa, lions (Panthera leo) are heavily persecuted in anthropogenic landscapes. Trans-disciplinary research and virtual boundaries (geofences) programmed into GPS-tracking transmitters offer new opportunities to improve coexistence. During a 24-month pilot study (2016-2018), we alerted communities about approaching lions, issuing 1,017 alerts to four villages and 19 cattle posts. Alerts reflected geofence breaches of nine lions (2,941 monitoring days) moving between Botswana’s Okavango Delta and adjacent agro-pastoral communities. Daily alert system costs per lion were US\$18.54, or \$5,460.24 per GPS deployment (n = 13). Alert-responsive livestock owners mainly responded by night-kraaling of cattle (68.9\%), significantly reducing their losses (by \$124.61 annually), whereas losses of control group and non-responsive livestock owners remained high (\$317.93 annually). Community satisfaction with alerts (91.8\%) was higher than for compensation of losses (24.3\%). Study lions spent 26.3\% of time monitored in geofenced community areas, but accounted for 31.0\% of conflict. Manual alert distribution proved challenging, static geofences did not appropriately reflect human safety or the environment’s strong seasonality that influenced cattle predation risk, and tracking units with on-board alert functions often failed or under-recorded geofence breaches by 27.9\%. These insufficiencies prompted the design of a versatile and autonomous lion alert platform with automated, dynamic geofencing. We co-designed this prototype platform with community input, thereby incorporating user feedback. We outline a flexible approach that recognizes conflict complexity and user community heterogeneity. Here, we describe the evolution of an innovative Information and Communication Technologies-based alert system that enables instant data processing and community participation through interactive interfaces on different devices. We highlight the importance of a trans-disciplinary co-design and development process focussing on community engagement while synthesising expertise from ethnography, ecology, and socio-informatics. We discuss the bio-geographic, social, and technological variables that influence alert system efficacy and outline opportunities for wider application in promoting coexistence and conservation.

  Women interested in computing are still facing several problems considering equality and career chances. Companies realize the opportunities of diversity and yet for several reasons they are struggling to hire or integrate young female professionals. Although gender study research provides promising frameworks there are still issues in applying them in working environments and practices. For this purpose, we made use of the Living Lab approach in the context of gender and IT. The Living Lab’s methodology offers opportunities to reveal new, relevant insights and create social change in a collaborative way. We stretched the existing understanding of this concept and follow a Participatory Action Research approach. In this paper we describe the setup of the Living Lab and present first insights from our research. We found that showing patience, organizing adequate spaces for reflection as well as facilitating motivation and trust is vital in such a sensitive research context.

  Sicherheitskritische Mensch-Computer-Interaktion ist nicht nur derzeit, sondern auch zukünftig ein äußerst relevantes Thema. 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.

  This paper describes the challenges which were faced by establishing a MediaSpace in the High Atlas in Morocco. The focus lies on the adaption of the wellestablished computer club approach within a steadily developing and profoundly transforming rural/mountainous region. This paper presents different aspects during the establishment process and contrasts these experiences with two other studies in different contexts, on the one hand inhabitants of refugee camps in Palestine and on the other hand, socially marginalized migrants in Germany. Findings show the importance of understanding the local context, involving local partners and integrating the needs and requirements of the local population to establish a sustainable intervention.

  Zusammenfassung {\textbar} Der wissenschaftliche Diskurs um die Relevanz gleichberechtigten Zugangs zu moderner Kommunikationstechnologie für gute soziale und wirtschaftliche Entwicklungschancen hat mit der ‚digitalen Kluft‘ ein eindrückliches Bild, das infolge unterschiedlich ausgeprägter Nutzung von Informations- und Kommunikationstechnologien (IKT) entstehende Wissensklüfte verdeutlicht. Mit der rasanten (Weiter-)Entwicklung moderner Technologien und der Verbreitung sozialer Medien sind die konkreten Ausprägungen dieser Klüfte in der interkulturellen Stadtgesellschaft in stetem Wandel begriffen. Die qualitative Studie untersucht die positiven sowie negativen Ausprägungen des ‚Digital Divide‘ unter älteren Migrantinnen am Beispiel einer mittleren Großstadt in Deutschland und diskutiert soziale Strukturen, die auf lokaler, nachbarschaftlicher Ebene als ausgleichende Faktoren wirken können.

  This poster describes the research around computer clubs in Palestinian refugee camps and the various lessons learned during the establishment of this intervention such the importance of the physical infrastructure (e.g. clean room, working hardware), soft technologies (e.g. knowledge transfer through workshops), social infrastructure (e.g. reliable partners in the refugee camp, partner from the university) and social capital (e.g. shared vision and values of all stakeholders). These important insights can be transferred on other interventions in similar unstable environments.

  Social media usage during the recent uprisings in Arabian countries has gained increasing attention in CHI research. This study adds to these insights by providing some findings on the use of ICT, specifically mobile media, by opposition forces and political activists during the Syrian civil war. The presented study is based on 17 interviews with Syrian FSA fighters, oppositional activists and refugees. A first analysis showed evidence for some very specific use patterns during wartime (compared to media usage of political activists under less anomic conditions). The study also describes a fragmented telecom infrastructure in today’s Syria: government-controlled regions offer fairly intact infrastructures while rebel-controlled regions are cut-off from telephone and internet. Moreover, the central and very critical role of mobile video for documenting, mobilization, and propaganda is discussed.

  Falls and fall-related injuries are a serious public health issue. Exercise programs can effectively reduce fall risk in older people. The iStoppFalls project developed an Information and Communication Technology-based system to deliver an unsupervised exercise program in older people’s homes. The primary aims of the iStoppFalls randomized controlled trial were to assess the feasibility (exercise adherence, acceptability and safety) of the intervention program and its effectiveness on common fall risk factors.

  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.

(2014)ICT-based system to predict and prevent falls (iStoppFalls): study protocol for an international multicenter randomized controlled trial.

  IN BMC geriatrics, Vol. 14, Pages: 91 doi:10.1186/1471-2318-14-91
  [BibTeX] [Abstract] [Download PDF]

  BACKGROUND: Falls are very common, especially in adults aged 65 years and older. Within the current international European Commission’s Seventh Framework Program (FP7) project ‚iStoppFalls‘ an Information and Communication Technology (ICT) based system has been developed to regularly assess a person’s risk of falling in their own home and to deliver an individual and tailored home-based exercise and education program for fall prevention. The primary aims of iStoppFalls are to assess the feasibility and acceptability of the intervention program, and its effectiveness to improve balance, muscle strength and quality of life in older people. METHODS/DESIGN: This international, multicenter study is designed as a single-blinded, two-group randomized controlled trial. A total of 160 community-dwelling older people aged 65 years and older will be recruited in Germany (n = 60), Spain (n = 40), and Australia (n = 60) between November 2013 and May 2014. Participants in the intervention group will conduct a 16-week exercise program using the iStoppFalls system through their television set at home. Participants are encouraged to exercise for a total duration of 180 minutes per week. The training program consists of a variety of balance and strength exercises in the form of video games using exergame technology. Educational material about a healthy lifestyle will be provided to each participant. Final reassessments will be conducted after 16 weeks. The assessments include physical and cognitive tests as well as questionnaires assessing health, fear of falling, quality of life and psychosocial determinants. Falls will be followed up for six months by monthly falls calendars. DISCUSSION: We hypothesize that the regular use of this newly developed ICT-based system for fall prevention at home is feasible for older people. By using the iStoppFalls sensor-based exercise program, older people are expected to improve in balance and strength outcomes. In addition, the exercise training may have a positive impact on quality of life by reducing the risk of falls. Taken together with expected cognitive improvements, the individual approach of the iStoppFalls program may provide an effective model for fall prevention in older people who prefer to exercise at home.

  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.
