    • Esau, M., Lawo, D., Castelli, N., Jakobi, T. & Stevens, G. (2021)Morning Routines between Calm and Engaging: Designing a Smart Mirror

      , Publisher: SciTePress, Science and Technology Publications, Pages: 58–69
      [BibTeX] [Abstract] [Download PDF]

      Frequently the main purpose of domestic artifacts equipped with smart sensors is to hide technology, like previous examples of a Smart Mirror show. However, current Smart Homes often fail to provide meaningful IoT applications for all residents’ needs. To design beyond efficiency and productivity, we propose to realize the potential of the traditional artifact for calm and engaging experiences. Therefore, we followed a design case study approach with 22 participants in total. After an initial focus group, we conducted a diary study to examine home routines and developed a conceptual design. The evaluation of our mid-fidelity prototype shows, that we need to study carefully the practices of the residents to leverage the physical material of the artifact to fit the routines. Our Smart Mirror, enhanced by digital qualities, supports meaningful activities and makes the bathroom more appealing. Thereby, we discuss domestic technology design beyond automation.

    • 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.

    • Castelli, N., Taugerbeck, S., Stein, M., Jakobi, T., Stevens, G. & Wulf, V. (2020)Eco-InfoVis at Work: Role-based Eco-Visualizations for the Industrial Context

      IN Proceedings of the ACM on Human-Computer Interaction, Vol. 4, Pages: 02:1–02:27 doi:10.1145/3375182
      [BibTeX] [Abstract] [Download PDF]

      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.

    • 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.

      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.
