    • Li, Q. (2021)Learning from the Past – The Use of Secondary Qualitative Material in a Design Education Context

      , Siegen, Germany
      [BibTeX] [Abstract] [Download PDF]

      In this thesis, I examine the use of qualitative data drawn from existing project material as a resource for design education. The use of second-hand qualitative data has been discussed extensively in relation to the ‘open science’ agenda, but its use as an educational resource has not. To investigate the extent to which second-hand qualitative data might be useful for analytic work, I conducted a study in which students were encouraged to use Grounded Design – a usercentred design approach in Siegen Social Informatic group- as a means to leverage data of this kind. Four design seminars were carried out to allow Master’s students participating in an HCI program access to substantial datasets collected in two long-term research projects that had finished some time previously. In the first seminar, the students were asked to select content from this dataset, analyse it, and then, on the basis of this, form conclusions about possible design opportunities. The study reveals a number of challenges and insights regarding what it takes to use qualitative data as a resource for design. After that, I involved students in the second and third seminar in the design process of preparing the secondary research data, namely designing tools and curating data. An artefact called DesignCaser was developed, and later, tested by the fourth seminar students. The evaluation of the processes undergone revealed both that students saw the exercise as useful and illuminating with respect to their understanding of how qualitative material can be used for design purposes but also, at the same time demonstrated some of the challenges involved. These were primarily to do with the amount of material, how it was curated, the nature of the data, and the time available to them.

    • Castelli, N. (2020)Designing Human-Centered Systems for the Internet of Things – Design-Case Study inspired Concept for End-User Data Work for tailorable information visualizations and analysis of IoT and IIoT Data

      Dissertation, Siegen
      [BibTeX] [Abstract] [Download PDF]

      The Internet of Things (IoT) and the Industrial Internet of Things (IIoT) are fast-growing emerging topics of technical, social, and economic significance that not only affect work practices but also daily routines and habits. The IoT and IIoT comprise a network of smart physical things and devices (such as production machines and home appliances). The number of “things” connected via the internet or the intranet is constantly increasing. It is estimated that approximately 20 billion IoT devices will be online by 2020 [179]. Internet of Things and IIoT devices communicate with one another through software technology with the aim of making them more autonomous and cooperative [334]. In addition to technological advances in hardware for the efficient acquisition and communication of context and status data, software solutions in particular offer great potential for influencing many areas of everyday life and work; to this end, humans should be taken into account when designing new digital systems. The central element here is the use of digital data, which are now available in greater quantities and at a better quality than ever before. Currently, the amount of data produced daily is 2.5 quintillion bytes–this will continue to increase in coming years [366]. These data contain much valuable information, which can only be obtained through appropriate data analyses and visualization and correct embedding in their context. The term “data work” has evolved as a superordinate area that combines all aspects of work with data to derive meaningful information, such as data consolidation, data processing, data refinement, data analysis, and data visualization [119]. This thesis focuses on end-user data work in the context of IoT and IIoT systems that supports users using their digital data by providing tailorable information visualizations and data analysis. From a Human Computer Interaction (HCI) perspective, this thesis examines how IoT and IIoT systems have to be designed to enable end-users to make digital data meaningful and usable. In this regard, and combining the areas of IoT system design, end-user development (EUD) and information visualization, the main goals of this thesis are: • To gain a deeper understanding of the use and appropriation of IoT and IIoT technology in different contexts, • To gain insights about the use of digital data for daily routines, habits and work practices; and • To evaluate possibilities for the development of a system design for end-user data work. This work is based on empirical field studies that investigate different settings (domestic and industrial) in the context of IoT and IIoT. Seen through the lens of appropriation [37, 99, 102, 291, 337], relevant practices for deploying and using IoT and IIoT technology, especially the practices of working with digital data to support routines, habits, and processes, are identified and discussed for different application areas. This has resulted in the development of system requirements to support the process of making abstract digital data accountable and meaningful for users in their everyday life and work practices. Grounded in these results, a concept of an end-user data work tool that allows the consolidation of digital data across system boundaries, lets users adjust the system to their context, supports flexible data visualizations, and empowers collaborative data work is presented.

    • Jakobi, T. (2019)Incorporating Usable Privacy into Connected Devices: A User-Centered Perspective

      Dissertation, Siegen
      [BibTeX] [Abstract]

      Due to the popularity of the Internet and the networked services that it facilitates, networked devices have become increasingly common in both the workplace and everyday life in recent years-following the trail blazed by smartphones. The data provided by these devices allow for the creation of rich user profiles. As a result, the collection, processing and exchange of such personal data have become drivers of economic growth. History shows that the adoption of new technologies is likely to influence both individual and societal concepts of privacy. Research into privacy has therefore been confronted with continuously changing concepts due to technological progress. From a legal perspective, privacy laws that reflect social values are sought. Privacy enhancing technologies are developed or adapted to take account of technological development. Organizations must also identify protective measures that are effective in terms of scalability and automation. Similarly, research is being conducted from the perspective of Human-Computer Interaction (HCI) to explore design spaces that empower individuals to manage their protection needs with regard to novel data, which they may perceive as sensitive. Taking such an HCI perspective with regard to understanding privacy management on the Internet ofThings (IoT), this research mainly focuses on three interrelated goals across the fields of application: 1. Exploring and analyzing how people make sense of data, especially when managing privacy and data disclosure; 2. Identifying, framing and evaluating potential resources for designing sense-making processes; and 3. Exploring the fitness of the identified concepts for inclusion in legal and technical perspectives on supporting decisions regarding privacy on the IoT. Although this work’s point of departure is the HCI perspective, it emphasizes the importance of the interrelationships among seemingly independent perspectives. Their interdependence is therefore also emphasized and taken into account by subscribing to a user-centered design process throughout this study. More specifically, this thesis adopts a design case study approach. This approach makes it possible to conduct full user-centered design lifecycles in a concrete application case with participants in the context of everyday life. Based on this approach, it was possible to investigate several domains of the IoT that are currently relevant, namely smart metering, smartphones, smart homes and connected cars. The results show that the participants were less concerned about (raw) data than about the information that could potentially be derived from it. Against the background of the constant collection of highly technical and abstract data, the content of which only becomes visible through the application of complex algorithms, this study indicates that people should learn to explore and understand these data flexibly, and provides insights in how to design for supporting this aim. From the point of view of design for usable privacy protection measures, the information that is provided to users about data disclosure should be focused on the consequences thereof for users’ environments and life. A related concept from law is “informed consent,” which I propose should be further developed in order to implement usable mechanisms for individual privacy protection in the era of the IoT. Finally, this thesis demonstrates how research on HCI can be methodologically embedded in a regulative process that will inform both the development of technology and the drafting of legislation.

      Using the domain of crisis management, Christian Reuter explores challenges and opportunities for technology design in emergent environments. He therefore empirically analyzes collaborative work in inter-organizational crisis – such as the police, fire departments, energy network operators and citizens – in order to identify collaboration practices that reveal work infrastructure limitations. He also designs, implements and evaluates novel concepts and ICT artifacts towards the support of emergent collaboration. Besides the discovery of potential organizational effects on the ability to deal with emergence he presents methodological implications for technology design.

    • Schubert, K. (2013)Wie nutzen Kinder digitale Medien? : Fallstudien der alltäglichen Nutzung von Computer und Internet durch 9- bis 10-jährige Kinder

      [BibTeX] [Abstract] [Download PDF]

      Seit Kinder Computer nutzen wird darüber kontrovers diskutiert. In der gesellschaftlichen Debatte wird oft über die Wirkung von Spielkonsolen, Computern und des Internet gestritten. Dabei folgen wissenschaftliche Untersuchungen zur Mediennutzung von Kindern häufig ausschließlich quantitativen Paradigmen. Ein differenzierender Blick auf die Nutzungs- und Aneignungspraxis digitaler Medien durch 9- bis 10-jährige Kinder in Deutschland fehlt jedoch. Diese Lücke mit Hilfe qualitativ erhobener und ausgewerteter Fallstudien zu schließen, ist Aufgabe der vorliegenden Untersuchung. Folgende Punkte bilden in diesen ausführlichen Fallstudien die Leitfragen: Wie, wo und wann nutzen 9- bis 10-jährige Kinder den Computer und andere digitale Medien in ihrem Alltag? Welche Rolle spielen die verschiedenen Medienwelten Familie, Peergroup und Schule sowie weitere Bezugspersonen der Kinder bei der Aneignung digitaler Medien? Wie steht die Nutzung digitaler Medien im Verhältnis zu den „klassischen“, „analogen“ Medien? Wie eignen sich Kinder digitale Medien an? Wie unterscheidet sich diese Aneignung im Vergleich zu anderen Medien? Die Arbeit verfolgt einen interdisziplinären Forschungsansatz und widmet sich bei den genannten Fragestellungen Themen, die sowohl für die Informatik als auch für Pädagogik und Medienforschung von hoher Relevanz sind. Der Schwerpunkt liegt dabei auf der Nutzung und Aneignung und nicht auf der Wirkung von Medien. Für die Untersuchung wird auf Methoden der qualitativen Sozialforschung zurückgegriffen. Als Werkzeuge kommen verschiedene Interviewformen und die teilnehmende Beobachtung zum Einsatz. Hervorzuheben ist hier das sogenannte „interaktive Interview “, welches aufgrund der Anforderungen des Forschungsfeldes im Rahmen dieser Arbeit entwickelt wurde. Als eine Art Mischform bereits bestehender Methoden ermöglicht das interaktive Interview einen besseren Zugang zum Feld und die Erhebung valider Daten. Bei der Auswertung des empirischen Materials werden dem Ansatz der Grounded Theory folgend mehrere Schlüsselkategorien, Dimensionen und Eigenschaften herausgearbeitet, die eine systematische Beschreibung einzelner Phänomene in den jeweiligen Fallstudien ermöglichen. In den Fallstudien werden insgesamt zehn Kinder untersucht, von denen drei für die Entwicklung der Schlüsselkategorien ausgewählt und kontrastierend ausführlicher gegenübergestellt werden. Die Schlüsselkategorien bilden dabei die Mediennutzung des Kindes, die Mediennutzung der Familie, die Medienaneignung des Kindes und die Medienerziehung des Kindes. Als Fazit ergibt sich ein deutlich differenziertes Bild der Bandbreite von Nutzungs- und Aneignungspraktiken bei Kindern. Die Mediennutzung der Kinder zeichnet sich durch eine große Vielfalt aus und ist einem dauerhaften Wandel unterworfen. Bei der alltäglichen Nutzung ist die jeweilige Medienwelt von entscheidender Bedeutung, in welcher sich das Kind gerade befindet. In diesen Medienwelten gelten sehr unterschiedliche Regeln, deren Bewusstwerden einen wichtigen Anteil an der Sozialisation der Kinder hat. Besonders hervorzuheben ist hier die Vorbildwirkung der elterlichen Nutzung der verschiedenen Medien. Neben den bestehenden drei Medienwelten Familie, Peergroup und Schule kann das Internet als eine neue, vierte Medienwelt definiert werden: sie hat Einfluss auf alle anderen Medienwelten und existiert in den meisten Fällen nicht losgelöst von diesen. Dabei stellen sich die bestehenden Medienwelten der zunehmenden alltäglichen Bedeutung des Internets und den damit verbundenen Herausforderungen sehr unterschiedlich. Übergreifend lässt sich dagegen in allen Medienwelten ein neuer Typ von Habitus bei der Nutzung digitaler Medien beobachten. Dieser „digitale Habitus“ ist dabei nicht als getrennt vom sonstigen Habitus des Kindes zu betrachten, vielmehr wird er neuer Bestandteil desselben: Die anfangs spielerische Nutzung und Geheimhaltung von Passwörtern zum Schutz der eigenen Privatsphäre sind ein typisches Merkmal des digitalen Habitus. Weitere Merkmale wie beispielsweise Strategien zum Korrigieren von Fehlern (durch Neustart bzw. „Neumachen“) können dabei auch als originär betrachtet werden und bilden einen wichtigen Anknüpfungspunkt für weitere Untersuchungen. Zu den wichtigsten Schlussfolgerungen gehört für die Informatik, digitale Medien für und mit Kindern zu gestalten, die eine gemeinsame Nutzungskultur von Kindern und Eltern fördern. In der Pädagogik besteht eine Herausforderung darin, sich zukünftig in der Lehrerausbildung wie auch den Schulen selbst verstärkt mit Spielen und sozialen Medien auseinanderzusetzen. Forschungsmethodisch spielen bei der Untersuchung sozialer Medien zunehmend auch ethische Probleme eine Rolle: Die Vermischung von Massen- und Individualkommunikation in den sozialen Medien konfrontiert Forscher bei der Erhebung, Auswertung und Veröffentlichung von empirischen Daten mit neuen und noch ungelösten Fragen.

Als Fazit ergibt sich ein deutlich differenziertes Bild der Bandbreite von Nutzungs- und Aneignungspraktiken bei Kindern. Die Mediennutzung der Kinder zeichnet sich durch eine große Vielfalt aus und ist einem dauerhaften Wandel unterworfen. Bei der alltäglichen Nutzung ist die jeweilige Medienwelt von entscheidender Bedeutung, in welcher sich das Kind gerade befindet. In diesen Medienwelten gelten sehr unterschiedliche Regeln, deren Bewusstwerden einen wichtigen Anteil an der Sozialisation der Kinder hat. Besonders hervorzuheben ist hier die Vorbildwirkung der elterlichen Nutzung der verschiedenen Medien. Neben den bestehenden drei Medienwelten Familie, Peergroup und Schule kann das Internet als eine neue, vierte Medienwelt definiert werden: sie hat Einfluss auf alle anderen Medienwelten und existiert in den meisten Fällen nicht losgelöst von diesen. Dabei stellen sich die bestehenden Medienwelten der zunehmenden alltäglichen Bedeutung des Internets und den damit verbundenen Herausforderungen sehr unterschiedlich. Übergreifend lässt sich dagegen in allen Medienwelten ein neuer Typ von Habitus bei der Nutzung digitaler Medien beobachten. Dieser „digitale Habitus“ ist dabei nicht als getrennt vom sonstigen Habitus des Kindes zu betrachten, vielmehr wird er neuer Bestandteil desselben: Die anfangs spielerische Nutzung und Geheimhaltung von Passwörtern zum Schutz der eigenen Privatsphäre sind ein typisches Merkmal des digitalen Habitus. Weitere Merkmale wie beispielsweise Strategien zum Korrigieren von Fehlern (durch Neustart bzw. „Neumachen“) können dabei auch als originär betrachtet werden und bilden einen wichtigen Anknüpfungspunkt für weitere Untersuchungen. Zu den wichtigsten Schlussfolgerungen gehört für die Informatik, digitale Medien für und mit Kindern zu gestalten, die eine gemeinsame Nutzungskultur von Kindern und Eltern fördern. In der Pädagogik besteht eine Herausforderung darin, sich zukünftig in der Lehrerausbildung wie auch den Schulen selbst verstärkt mit Spielen und sozialen Medien auseinanderzusetzen. Forschungsmethodisch spielen bei der Untersuchung sozialer Medien zunehmend auch ethische Probleme eine Rolle: Die Vermischung von Massen- und Individualkommunikation in den sozialen Medien konfrontiert Forscher bei der Erhebung, Auswertung und Veröffentlichung von empirischen Daten mit neuen und noch ungelösten Fragen.},
