    ABIS 2024 - International Workshop on Personalization and Recommendation
    (Mensch und Computer 2024 - Workshopband, 2024) Neumayr, Thomas; Yigitbas, Enes; Augstein, Mirjam; Herder, Eelco; Stojko, Laura; Strecker, Jannis
    ABIS is an international workshop, organized by the SIG on Adaptivity and User Modeling in Interactive Software Systems of the German Gesellschaft für Informatik. For more than 25 years, the ABIS Workshop has been a highly interactive forum for discussing the state of the art in personalization, user modeling, and related areas. ABIS 2024’s focus will be on the topics of personalization and recommendation within the areas of Computer-Supported Cooperative Work (CSCW) (i.e., support of individuals who work organized in groups), Cross-Reality (XR) Interaction (e.g., transitions inside the reality-virtuality continuum), and/or making sense of sensory data for personalization purposes. To discuss such questions, our workshop aims to bring together researchers and practitioners who are interested in the general personalization domain, and/or in our SIG’s current focus. Our goal is to identify current issues and future directions of research and foster future development of the discipline and collaborations.

    Activity Support For Seniors Using Public Displays: A Proof Of Concept
    (Mensch und Computer 2021 - Tagungsband, 2021) Fietkau, Julian; Stojko, Laura
    Seniors face many challenges in their daily activities regarding mobility and accessibility. We have designed and prototyped a system of networked public displays to support them, particularly regarding outdoor pedestrian navigation. This article describes the process and results of a qualitative evaluation of this prototype system, which was conducted with seven participants, a mixture of older adults and experts on geriatric care. Based on insights gained from these interviews, we provide guidance on the design of outdoor activity support systems for seniors.

    Design guidelines for micro information radiators to increase seniors' safety in urban space
    (Mensch und Computer 2020 - Tagungsband, 2020) Stojko, Laura; Fietkau, Julian; Koch, Michael
    Senior citizens face challenges during activities in urban space. To help and motivate them pursuing outside activities, we propose a network of micro information radiators to increase their feeling of safety. In this paper we first collect guidelines and relevant aspects for the design of micro information radiators. Then we summarize our own experiences from a project designing smart urban objects – particularly giving an overview of design guidelines for input and output interaction of micro information radiators.

    Designing Smart Urban Objects - Adaptation, Multi-user Usage, Walk-up-and-use and Joy of Use
    (2021) Koch, Michael; Fietkau, Julian; Stojko, Laura; Buck, Anna
    Designing human-computer interaction for non-personal computing devices in urban space poses different challenges than designing for personal devices. In this paper we summarize the findings from a project developing smart urban objects to help elderly people participate in urban life. We present four key challenges that have been identified designing such objects, and present first ideas for how to address these challenges. The four key challenges are adaptability (and data privacy), multi-user usage, walk-up-and-use and joy of use.

    A Holistic Approach: Personalizing Large Semi-Public Displays for Intercultural Groups
    (Mensch und Computer 2024 - Workshopband, 2024) Stojko, Laura
    Personalizing user interfaces increases usability and user experience. Focusing on large-semi public displays as technology that shares its user interface with diverse people raises the question of whether and how personalization can occur and what kind of user involvement can be expected. Considering cultural design preferences for personalization is especially interesting, as it has been shown to increase usability within single-user applications. Therefore, this paper summarizes and clarifies the potential of personalization and user involvement in combination with large semi-public displays, which should be used by several users, considering cultural design preferences, and describes the challenges in this process. As a result, 15 culturally relevant user interface aspects were identified and assigned to personalization paradigms for a holistic analysis of their potential. This result provides a general basis for cultural adaptations and discussions about user involvement in the design process of large semi-public displays.

    Mensch-Technik-Interaktion mit smarten städtebaulichen Objekten - Entwicklung und Evaluation
    (2020) Koch, Michael; Fietkau, Julian; Stojko, Laura; Buck, Anna
    Die Selbstbestimmung älterer Menschen wird wesentlich davon bestimmt, sich sicher in ihrer jeweiligen Umgebung bewegen zu können. Nachlassende Fähigkeiten zur Interaktion mit der Umgebung schränken die soziale und kulturelle Teilhabe Älterer jedoch ein bis hin zur sozialen Isolation. Hier eröffnen Methoden der Mensch-Technik-Interaktion (MTI) vielfältige neue Möglichkeiten, altersbedingte Einschränkungen auszugleichen. Dieser Bericht beschreibt die Ergebnisse des Verbundvorhabens UrbanLife+, dessen Zielsetzung es war, die Potenziale von MTI-Innovationen in einem übergeordneten Safety-Konzept zu identifizieren, zu integrieren, ihre Wirksamkeit und Nützlichkeit besser zu verstehen und praktische Erfahrungen in der Stadt Mönchengladbach zu sammeln. Aus einer Anforderungsanalyse wurden neben Personas und konkreten Szenarien verschiedene Konzepte für smarte städtebauliche Objekte (SSO) entwickelt und einige davon in Prototypen umgesetzt. Insbesondere wurden von der Universität der Bundeswehr (UBW) smarte interaktive Informationsdisplays und Mikro-Informationsstrahler mit einem vernetzenden Aktivitätsunterstützungsdienst in mehreren Iterationen umgesetzt und evaluiert. Bei der Evaluation wurden dabei neue Konzepte für die Evaluation im urbanen Raum entwickelt und teilweise erprobt. Ergebnisse des (Teil-)Projektes sind neben den Prototypen insbesondere eine Reihe von Gestaltungsempfehlungen für SSO.

    Personalizing Large Information Radiators Using Emotion Recognition
    (Mensch und Computer 2023 - Workshopband, 2023) Stojko, Laura; Koch, Michael
    Knowledge exchange in corporate settings can be facilitated by using large interactive displays, information radiators, displaying information about employees, current work topics, and projects. This paper gathers ideas about how to enhance the user’s experience proactively using emotion recognition and how this could be useful for personalizing the interaction. Based on the literature, ideas of how this could be done are described. This should encourage discussions and creative visions about how to use emotion recognition as implicit user feedback for personalization.

    Reflecting on a Smart City Project for Older Adults
    (Mensch und Computer 2024 - Workshopband, 2024) Fietkau, Julian; Stojko, Laura
    Between 2015 and 2020 we participated in a joint research project to explore technological interventions fostering participation of older adults in urban spaces. UrbanLife+ involved multi-year qualitative and quantitative empirical work on obstacles faced by people aged 65 and up living in cities. This brief retrospective does not recap the previously published results of the project, but summarizes methodological and organizational insights as well as pragmatic experiences gathered during its runtime that have not yet been discussed publicly. We focus on aspects relevant for future urban technology projects aiming for accessibility and inclusivity. These include issues navigating interdisciplinary design teams, conducting questionnaire studies with older adults, maintaining participatory design principles with geographically distributed teams, and conducting empirical evaluations during the COVID-19 pandemic.

    Setting up a long term evaluation environment for interactive semi-public information displays
    (Mensch und Computer 2023 - Workshopband, 2023) Koch, Michael; Fietkau, Julian; Stojko, Laura
    Human-computer interaction research increasingly focuses on the long-term evaluation of real-world field deployments. When dealing with innovative solutions and when asking for the possibility to do action research in the deployment, fitting real-world deployments are hard to find – and access to these deployments is hard to obtain. We decided to invest in setting up and managing a long-term deployment of an interactive large information screen solution at our university, which includes several displays. In this paper, we briefly report about the installation – the CommunityMirror Network – as well as its functionality and operations management.

    Towards new realities: implications of personalized online layers in our daily lives
    (i-com: Vol. 23, No. 2, 2024) Herder, Eelco; Stojko, Laura; Strecker, Jannis; Neumayr, Thomas; Yigitbas, Enes; Augstein, Mirjam
    We are currently in a period of upheaval, as many new technologies are emerging that open up new possibilities to shape our everyday lives. Particularly, within the field of Personalized Human-Computer Interaction we observe high potential, but also challenges. In this article, we explore how an increasing amount of online services and tools not only further facilitates our lives, but also shapes our lives and how we perceive our environments. For this purpose, we adopt the metaphor of personalized ‘online layers’ and show how these layers are and will be interwoven with the lives that we live in the ‘human layer’ of the real world.
