Empowering users to control their privacy in context-aware system through interactive consent

Context-aware systems adapt their behaviour based on the context a user is in. Since context is potentially privacy sensitive information, users should be empowered to control how much of their context they are willing to share, under what conditions and for what purpose. We propose an interactive consent mechanism that allows this. It is interactive in the sense that users are asked for consent when a request for their context information is received. Our interactive consent mechanism complements a more traditional pre-configuration approach. We describe the architecture, the implementation of our interactive consent mechanism and a use case

Scared or naïve? An exploratory study on users perceptions of online privacy disclosures

Online service providers offer “free” services in exchange for the personal data of its users. In the last few years there has been an increase of online industry regulations requiring service providers, such as websites and app developers, to disclosure the ways in which they collect, process and use the personal data of service users. These “privacy disclosures,” such as the privacy policy, the cookie notice and, on smart phones, the app permission request, are designed with the purpose of informing users and empowering them to control their privacy. The interaction problems with these different types of disclosure are relatively well understood – habituation, inattention and cognitive biases undermine the extent to which user consent is truly informed. Users understanding of the actual content of these disclosures, and their feelings toward it, are less well understood, though. In this paper we report the results of a mixed-method exploratory study of the privacy disclosures and compare their relative merits as a starting point for the development of more meaningful consent interactions. First, we conducted a focus group study, with 21 students from the University of Southampton, to understand behavior and privacy concerns of Millenials (those born between 1982 and 2004) in response to the these three most common types of privacy disclosure. Second, we conducted an online survey, with 100 students from the University of Southampton, to study perception and feelings towards the content of the privacy disclosures. We identify three key findings. Firstly, we find heterogeneity of user perceptions and attitudes to privacy disclosures in both studies. The results of the focus groups suggests three types of users: the scared and worried about their online privacy, who think there is an option out; the naïve, who do not understand how their personal data is collected and processed by the online service providers; and the meh, who understand the trade off but are not worried about their privacy. Secondly, we find limited ability of users to infer data processing outputs and risks based on technical explanations of particular practices, suggestions of a naïve model of “cost justification” rather cost-benefit analysis by users. Finally, we show evidence of the possibility that consent interactions are valuable in themselves as a mean to improve user perceptions of a servic

Ethical and methodological issues in engaging young people living in poverty with participatory research methods

This paper discusses the methodological and ethical issues arising from a project that focused on conducting a qualitative study using participatory techniques with children and young people living in disadvantage. The main aim of the study was to explore the impact of poverty on children and young people's access to public and private services. The paper is based on the author's perspective of the first stage of the fieldwork from the project. It discusses the ethical implications of involving children and young people in the research process, in particular issues relating to access and recruitment, the role of young people's advisory groups, use of visual data and collection of data in young people's homes. The paper also identifies some strategies for addressing the difficulties encountered in relation to each of these aspects and it considers the benefits of adopting participatory methods when conducting research with children and young people

Design for Empowerment: Empowering Sri Lankan Farmers through Mobile-based Information System

We developed a mobile-based information system (MBIS) to empower users to improve their livelihood activities. To do so, we first developed an empowerment framework (since one does not exist) as a basis to develop the MBIS. In particular, we conducted this research to solve an agriculture over-production problem in Sri Lanka where farmers remain trapped in a poverty cycle. They cannot make informed decisions due to lack of access to timely, context-based actionable information to achieve a good revenue. We had to generate some essential information such as current production level in real-time by capturing farmers’ decisions such as what and how much to grow. For this purpose, we needed to empower farmers to actively engage them in informed decision-making process through the MBIS. In evaluating the impact of the MBIS, we found a statistically significant positive change in farmers’ empowerment levels based on measuring self-efficacy, sense of control, and motivation before and after they used the application. Commercial organizations have since adopted this mobile-based system in India and Sri Lanka to solve agricultural problems, in universities Africa to mitigate hidden hunger, and the Corporative Research Center in Australia to develop digital health applications to manage chronic diseases, which indicates the approach’s wide adoptability

Innovative public governance through cloud computing: Information privacy, business models and performance measurement challenges

Purpose: The purpose of this paper is to identify and analyze challenges and to discuss proposed solutions for innovative public governance through cloud computing. Innovative technologies, such as federation of services and cloud computing, can greatly contribute to the provision of e-government services, through scaleable and flexible systems. Furthermore, they can facilitate in reducing costs and overcoming public information segmentation. Nonetheless, when public agencies use these technologies, they encounter several associated organizational and technical changes, as well as significant challenges. Design/methodology/approach: We followed a multidisciplinary perspective (social, behavioral, business and technical) and conducted a conceptual analysis for analyzing the associated challenges. We conducted focus group interviews in two countries for evaluating the performance models that resulted from the conceptual analysis. Findings: This study identifies and analyzes several challenges that may emerge while adopting innovative technologies for public governance and e-government services. Furthermore, it presents suggested solutions deriving from the experience of designing a related platform for public governance, including issues of privacy requirements, proposed business models and key performance indicators for public services on cloud computing. Research limitations/implications: The challenges and solutions discussed are based on the experience gained by designing one platform. However, we rely on issues and challenges collected from four countries. Practical implications: The identification of challenges for innovative design of e-government services through a central portal in Europe and using service federation is expected to inform practitioners in different roles about significant changes across multiple levels that are implied and may accelerate the challenges' resolution. Originality/value: This is the first study that discusses from multiple perspectives and through empirical investigation the challenges to realize public governance through innovative technologies. The results emerge from an actual portal that will function at a European level. © Emerald Group Publishing Limited

Designing for empowerment

Technology bears the potential to empower people - to help them tackle challenges they would otherwise give up on or not even try, to make experiences possible they did not have access to before. One type of such technologies - the application area of this thesis - is health and wellbeing technology (HWT), such as digital health records, physical activity trackers, or digital fitness coach applications. HWTs often claim to empower people to live healthier and happier lives. However, there is reason to challenge and critically reflect on these claims and underlying assumptions as more and more researchers are finding that technologies aiming or claiming to be empowering often turn out to be disempowering. This critical reflection is the starting point of this thesis: Can HWTs really empower people in their everyday lives? If so, how should we go about designing them to foster empowerment and avoid disempowerment? To this aim, this thesis makes three main contributions: First, it presents a framework of empowering technologies that aims to introduce conceptual and terminological clarity of empowerment in the field of Human-Computer Interaction (HCI). As a literature review conducted for this thesis reveals, the understandings of empowerment in HCI diverge substantially, rendering the term a subsumption of diverse research endeavors. The presented framework is informed by the results of the literature review as well as prior work on empowerment in social sciences, psychology, and philosophy. It aims to help other researchers to analyze conceptual differences between their own work and others’ and to position their research projects. In the same way, this thesis uses the proposed framework to analyze and reflect on the conducted case studies. Second, this thesis explores how HWT can empower people in a number of studies. Technologies that are investigated in these studies are divided into three interaction paradigms (derived from Beaudouin-Lafon’s interaction paradigms): Technologies that follow the computer-as-tool paradigm include patient-controlled electronic health records, and physical activity trackers; technologies in the computer-as-partner paradigm include personalized digital fitness coaches; and technologies in the computer-as-intelligent-tool paradigm includes transparently designed digital coaching technology. For each of these paradigms, I discuss benefits and shortcomings, as well as recommendations for future work. Third, I explore methods for designing and evaluating empowering technology. Therefore, I analyze and discuss methods that have been used in the different case studies to inform the design of empowering technologies such as interviews, observations, personality tests, experience sampling, or the Theory of Planned Behavior. Further, I present the design and evaluation of two tools that aimed to help researchers and designers evaluate empowering technologies by eliciting rich, contextualized feedback from users and fostering an empathic relationship between users and designers. I hope that my framework, design explorations, and evaluation tools will serve research on empowering technologies in HCI to develop a more grounded understanding, a clear research agenda, and inspire the development of a new class of empowering HWTs.Technologie für Empowerment — im Deutschen am besten mit Befähigung oder Ermächtigung übersetzt: diese Vision ist sowohl in medizinischen und technischen Fachkreisen als auch in der wissenschaftlichen Literatur im Feld Mensch-Maschine Interaktion (MMI) weit verbreitet. Technologie kann — laut dieser Vision — Menschen helfen Herausforderungen zu meistern, die sie sonst nicht schaffen oder nicht mal versuchen würden, oder Ihnen komplett neue Erfahrungen ermöglichen. Eine Art von “empowernden”, also befähigenden Technologien sind Technologien für Gesundheit und Wohlbefinden (health and wellbeing technologies, HWT), wie beispielsweise digitale Krankenakten, Schrittzähler, oder digitale Fitnesstrainer. Sowohl Werbung als auch Forschung über HWTs preist diese häufig als Schlüssel zu einem gesünderen und glücklicheren Leben an. Es gibt aber durchaus Gründe diesen Behauptungen kritisch gegenüberzustehen. So haben bereits einige Forschungsprojekte über vermeintlich “empowernde” Technologien ergeben, dass diese eher entmächtigen — also Ihre Nutzer mehr einschränken als Ihnen mehr Möglichkeiten zu verschaffen. Eine kritische Reflexion der Annahme, dass HWTs ihre Nutzer empowern stellt den Ausgangspunkt dieser Dissertation dar: Können HWTs ihre Nutzer wirklich empowern? Falls dem so ist, wie sollten sie am besten gestaltet werden? Der Beitrag meiner Dissertation zur Beantwortung dieser Fragen wird in drei Teilen präsentiert: Im ersten Teil stelle ich ein konzeptuelles Framework vor, mit dem Ziel terminologische Klarheit im Bereich Empowerment in MMI zu fördern. Eine Literaturanalyse im Rahmen dieser Dissertation hat ergeben, dass die Verwendungen des Begriffs “Empowerment” in der MMI Literatur sehr stark voneinander abweichen. Beispielsweise wird der Begriff in Literatur über Technologien für Barrierefreiheit anders verstanden als in Literatur über Technologien für bürgerliches Engagement. Folglich schert das Schlagwort “Technologien für Empowermen”, das in Präsentationen und Denkschriften weit verbreitet ist, komplett unterschiedliche Ansätze über einen Kamm. Das Framework, das in dieser Dissertation vorgestellt wird, zeigt die Unterschiede und Gemeinsamkeiten bei der Verwendung des Empowermentbegriffs auf. Es entstand als Resultat der Literaturanalyse und integriert gleichzeitig Erkenntnisse von Empowermenttheorien die in Sozialwissenschaften, Psychologie und Philosophie diskutiert wurden. In dieser Dissertation wird das vorgestellte Framework verwendet, um die präsentierten Studien über HWTs einzuordnen und zu diskutieren. Im zweiten Teil präsentiere ich verschiedene empirische und technische Studien mit dem Ziel zu verstehen wie HWTs Menschen empowern können. Die Technologien, die dabei untersucht werden teile ich in drei Interaktionsparadigmen ein (die von den Interaktionsparadigmen von Beaudouin-Lafon abgeleitet sind): Technologien im Paradigma Computerals- Werkzeug sind beispielsweise digitale Krankenakten und Schrittzähler; Technologien im Paradigma Computer-als-Partner sind beispielsweise digitale personalisierte Fitnesstrainer und Technologien im Paradigma Computer-als-intelligentes-Werkzeug sind beispielsweise transparent gestaltete digitale personalisierte Gesundheitsberater oder Fitnesstrainer. Vorund Nachteile von Technologien in diesen drei Paradigmen werden diskutiert und Empfehlungen für zukünftige Forschung in diesen Bereichen abgeleitet. Im dritten Teil, untersuche ich, welche Methoden für die Gestaltung und Evaluierung von empowernden Technologien geeignet sind. Einerseits diskutiere ich die Vor- und Nachteile der Methoden, die in den einzelnen Untersuchungen von HWTs (im zweiten Teil) verwendet wurden, wie zum Beispiel Interviews, Observationen, die Experience Sampling Methode oder Fragebögen basierend auf der Theorie des geplanten Verhaltens. Andererseits berichte ich über die Gestaltung und Entwicklung von zwei Applikationen mit dem Ziel Forschern und Designern die Evaluation von empowernden Technologien zu erleichtern. Konkret hat die erste Applikation das Ziel es Testnutzern zu ermöglichen immer und überall für sie wichtige Aspekte des Nutzererlebnisses an das Entwicklungsteam weiterzugeben. Bei der Entwicklung der zweiten Applikation stand dagegen die Förderung von Empathie zwischen Nutzern und Designern im Vordergrund. Ich hoffe, dass das vorgestellte Framework, die Studien über HWTs und Evaluationswerkezeuge die Forschung über empowernde Technologien voranbringen, zu einer klaren Forschungsagenda beitragen, und die Entwicklung von neuartigen HWTs anregen werden
