    • Pins, D., Jakobi, T., Boden, A., Alizadeh, F. & Wulf, V. (2021)Alexa, We Need to Talk: A Data Literacy Approach on Voice Assistants

      Voice assistants (VA) collect data about users’ daily life including interactions with other connected devices, musical preferences, and unintended interactions. While users appreciate the convenience of VAs, their understanding and expectations of data collection by vendors are often vague and incomplete. By making the collected data explorable for consumers, our research-through-design approach seeks to unveil design resources for fostering data literacy and help users in making better informed decisions regarding their use of VAs. In this paper, we present the design of an interactive prototype that visualizes the conversations with VAs on a timeline and provides end users with basic means to engage with data, for instance allowing for filtering and categorization. Based on an evaluation with eleven households, our paper provides insights on how users reflect upon their data trails and presents design guidelines for supporting data literacy of consumers in the context of VAs.

    • Jakobi, T., Stevens, G., von Grafenstein, M., Pins, D. & Boden, A. (2020)User-friendly formulation of data processing purposes of voice assistants: a user perspective on the principle of purpose limitation

      In 2019 it was revealed that several providers of voice assistants had systematically evaluated voice recordings of their users. Since the data protection notices stated that data would also be used to improve the service, this use was legal. For the users, however, this evaluation represented a clear break with their expectations of privacy. The purpose limitation principle of the GDPR with its component of purpose specification requires flexibility for the processor as well as transparency for the consumer. Against the background of this conflict of interest, the question arises for HCI as to how processing purposes of voice assistants should be designed to meet both requirements. To collect a user perspective, this study first analyzes the data protection information of the dominant voice assistants. Based on this, we present results of focus groups that deal with the perceived processing of data of voice assistants from the user perspective. The study shows that existing purpose statements offer hardly any transparency for consumers regarding the consequences of data processing and do not have any restrictive effect with regard to legal data use. Our results on risks perceived by users allow us to draw conclusions about the user-friendly design of processing purposes in terms of a design resource.

    • Jakobi, T., Stevens, G., von Grafenstein, M., Pins, D. & Boden, A. (2020)Die nutzerInnenfreundliche Formulierung von Zwecken der Datenverarbeitung von Sprachassistenten

      [BibTeX] [Abstract] [Download PDF]

      2019 wurde bekannt, dass mehrere Anbieter von Sprachassistenten Sprachaufnahmen ihrer NutzerInnen systematisch ausgewertet haben. Da in den Datenschutzhinweisen angegeben war, dass Daten auch zur Verbesserung des Dienstes genutzt würden, war diese Nutzung legal. Für die NutzerInnen stellte diese Auswertung jedoch einen deutlichen Bruch mit ihren Privatheitsvorstellungen dar. Das Zweckbindungsprinzip der DSGVO mit seiner Komponente der Zweckspezifizierung fordert neben Flexibilität für den Verarbeiter auch Transparenz für den Verbraucher. Vor dem Hintergrund dieses Interessenkonflikts stellt sich für die HCI die Frage, wie Verarbeitungszwecke von Sprachassistenten gestaltet sein sollten, um beide Anforderungen zu erfüllen. Für die Erhebung einer Nutzerperspektive analysiert diese Studie zunächst Zweckangaben in den Datenschutzhinweisen der dominierenden Sprachassistenten. Darauf aufbauend präsentieren wir Ergebnisse von Fokusgruppen, die sich mit der wahrgenommenen Verarbeitung von Daten von Sprachassistenten aus Nutzersicht befassen. Es zeigt sich, dass bestehende Zweckformulierungen für VerbraucherInnen kaum Transparenz über Folgen der Datenverarbeitung bieten und keine einschränkende Wirkung im Hinblick auf legale Datennutzung erzielen. Unsere Ergebnisse über von Nutzern wahrgenommene Risiken erlauben dabei Rückschlüsse auf die anwenderfreundliche Gestaltung von Verarbeitungszwecken im Sinne einer Design-Ressource.

      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.

    • Alizadeh, F., Jakobi, T., Boldt, J. & Stevens, G. (2019)GDPR-Reality Check on the Right to Access Data: Claiming and Investigating Personally Identifiable Data from Companies

      Loyalty programs are early examples of companies commercially collecting and processing personal data. Today, more than ever before, personal information is being used by companies of all types for a wide variety of purposes. To limit this, the General Data Protection Regulation (GDPR) aims to provide consumers with tools to control data collection and processing. What this right concretely means, which types of tools companies have to provide to their customers and in which way, is currently uncertain because precedents from case law are missing. Contributing to closing this gap, we turn to the example of loyalty cards to supplement current implementations of the right to claim data with a user perspective. In our hands-on approach, we had 13 households request their personal data from their respective loyalty program. We investigate expectations of GDPR in general and the right to access in particular, observe the process of claiming and receiving, and discuss the provided data takeouts. One year after the GDPR has come into force, our findings highlight the consumer’s expectations and knowledge of the GDPR and in particular the right to access to inform design of more usable privacy enhancing technologies.

      [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.

      [BibTeX] [Abstract] [Download PDF]

      One of the great societal challenges that we face today concerns the move to more sustainable patterns of energy consumption, reflecting the need to balance both individual consumer choice and societal demands. In order for this ‘energy turnaround‘ to take place, however, reducing residential energy consumption must go beyond using energy-efficient devices: More sustainable behaviour and lifestyles are essential parts of future ‘energy aware‘ living. Addressing this issue from an HCI perspective, this paper presents the results of a 3-year research project dealing with the co-design and appropriation of a Home Energy Management System (HEMS) that has been rolled out in a living lab setting with seven households for a period of 18 months. Our HEMS is inspired by feedback systems in Sustainable Interaction Design and allows the monitoring of energy consumption in real-time. In contrast to existing research mainly focusing on how technology can persuade people to consume less energy (‘what technology does to people‘), our study focuses on the appropriation of energy feedback systems (‘what people do with technology‘) and how newly developed practices can become a resource for future technology design. Therefore, we deliberately followed an open research design. In keeping with this approach, our study uncovers various responses, practices and obstacles of HEMS use. We show that HEMS use is characterized by a number of different features. Recognizing the distinctive patterns of technology use in the different households and the evolutionary character of that use within the households, we conclude with a discussion of these patterns in relation to existing research and their meaning for the design of future HEMSs.

Addressing this issue from an HCI perspective, this paper presents the results of a 3-year research project dealing with the co-design and appropriation of a Home Energy Management System (HEMS) that has been rolled out in a living lab setting with seven households for a period of 18 months. Our HEMS is inspired by feedback systems in Sustainable Interaction Design and allows the monitoring of energy consumption in real-time. In contrast to existing research mainly focusing on how technology can persuade people to consume less energy (‘what technology does to people'), our study focuses on the appropriation of energy feedback systems (‘what people do with technology') and how newly developed practices can become a resource for future technology design. Therefore, we deliberately followed an open research design. In keeping with this approach, our study uncovers various responses, practices and obstacles of HEMS use. We show that HEMS use is characterized by a number of different features. Recognizing the distinctive patterns of technology use in the different households and the evolutionary character of that use within the households, we conclude with a discussion of these patterns in relation to existing research and their meaning for the design of future HEMSs.},

      Residential and commercial buildings are responsible for about 40\% of the EU’s total energy co n- sumption. However, conscious, sustainable use of this limited resource is hampered by a lack of visibility and materiality of consumption. One of the major challenges is enabling consumers to make informed decisions about energy consumption, thereby supporting the shift to sustainable a c- tions. With the use of Energy-Management-Systems it is possible to save up to 15\%. In recent years, design approaches have greatly diversified, but with the emergence of ubiquitous- and co n- text-aware computing, energy feedback solutions can be enriched with additional context info r- mation. In this study, we present the concept “ room as a context ” for eco-feedback systems. We investigate opportunities of making current state- of-the-art energy visualizations more meaningful and demonstrate which new forms of visualizations can be created with this additional info r- mation. Furthermore, we developed a prototype for android-based tablets, which includes some of the presented features to study our design concepts in the wild.
