- KonferenzbeitragActivity Support For Seniors Using Public Displays: A Proof Of Concept(Mensch und Computer 2021 - Tagungsband, 2021) Fietkau, Julian; Stojko, LauraSeniors 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.
- KonferenzbeitragDesign guidelines for micro information radiators to increase seniors' safety in urban space(Mensch und Computer 2020 - Tagungsband, 2020) Stojko, Laura; Fietkau, Julian; Koch, MichaelSenior 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.
- ReportDesigning Smart Urban Objects - Adaptation, Multi-user Usage, Walk-up-and-use and Joy of Use(2021) Koch, Michael; Fietkau, Julian; Stojko, Laura; Buck, AnnaDesigning 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.
- ReportMensch-Technik-Interaktion mit smarten städtebaulichen Objekten - Entwicklung und Evaluation(2020) Koch, Michael; Fietkau, Julian; Stojko, Laura; Buck, AnnaDie 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.
- WorkshopbeitragPersonalizing Large Information Radiators Using Emotion Recognition(Mensch und Computer 2023 - Workshopband, 2023) Stojko, Laura; Koch, MichaelKnowledge 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.
- WorkshopbeitragSetting up a long term evaluation environment for interactive semi-public information displays(Mensch und Computer 2023 - Workshopband, 2023) Koch, Michael; Fietkau, Julian; Stojko, LauraHuman-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.
- WorkshopbeitragUsing an Elastic Stack as a Base for Logging and Evaluation of Public Displays(Mensch und Computer 2023 - Workshopband, 2023) Rohde, Christopher; Koch, Michael; Stojko, LauraThis paper describes the usage of the Elastic Stack as a powerful and flexible base for capturing, storing, analyzing, and visualizing log data, as well as conducting evaluations of public displays. Nowadays, public displays are an essential element in providing information from a variety of applications and systems. As 24/7 in-person observations are impossible, support is needed for evaluation of the usage for single unit installations as well as large-scale public display networks. A software-supported solution can automate the most common data collection steps and provide a common base for further evaluation. In this paper, we present an ongoing case study on our technical solution for supporting long-term 24/7 evaluation with the Elastic Stack in any kind of public display installation. The solution is based on a logging framework and the Elasticsearch, Logstash, and Kibana – tool stack. We present the technical solution, the requirements for our implementation, and possible evaluation approaches.
