    Age-dependent health data visualizations: a research agenda
    (Mensch und Computer 2016 – Workshopband, 2016) Theis, Sabine; Bröhl, Christina; Rasche, Peter; Wille, Matthias; Schlick, Christopher M.; Mertens, Alexander
    While current data visualization research is profoundly driven by innovation and technical aspects, the project Tech4Age focusses on the evaluation of human factors in health-related data and information visualization. This workshop paper initially describes the background and motivation of ergonomic health-data visualization research. Subsequently we present planned studies as well as preliminary results from one general and one task-dependent study which we see as basis for generalizable results of ongoing ergonomic health-visualization evaluations. Finally, we present the research design of an evaluation study aiming at general recommendations for the age-differentiated design of health data visualizations.

    Best Practices for Designing Electronic Healthcare Devices and Services for the Elderly
    (i-com: Vol. 15, No. 1, 2016) Wille, Matthias; Theis, Sabine; Rasche, Peter; Bröhl, Christina; Schlick, Christopher; Mertens, Alexander
    Demographic change and associated shifts in the age structure lead to major challenges in health processes. One way to address this is to increase the use of telemedicine systems and services to ensure non-local yet individualized patient care, such as in rural areas. When considering new medical technology components, we must compensate for age-related changes in perception, cognition and motor skills to achieve user-centered design and take into account psychophysical effect relationships to achieve sustainable acceptance for technology integration. This paper presents various best-practice examples for participatory investigation into influencing factors, with a focus on the different times and periods within the lifecycle of a telemedical product and associated services. In addition to giving concrete design hints derived from individual studies, the paper discusses the strengths and weaknesses of the paradigms used and provides recommendations for user-centric development with old and very old patients.

    Partizipative Technikentwicklung
    (INFORMATIK 2017, 2017) Wille, Matthias; Rasche, Peter; Bröhl, Christina; Theis, Sabine; Seinsch, Tobias; Mertens, Alexander
    In diesem Beitrag wird die Konzeption, Realisierung und Validierung einer visuellen Umsetzung von Datensicherheitsaspekten in Healthmonitoring-Apps skizziert. Eingangs wird die Notwendigkeit solcher Visualisierung motiviert; anschließend wird der aktuellen Stand der Forschung in diesem Bereich kurz erläutert; schließlich wird die Konzeption der Datenschutzvideos dargestellt.

    Use of Information and Communication Technology in Healthcare Context by Older Adults in Germany: Initial Results of the Tech4Age Long-Term Study
    (i-com: Vol. 16, No. 2, 2017) Mertens, Alexander; Rasche, Peter; Theis, Sabine; Bröhl, Christina; Wille, Matthias
    In 2016 the interdisciplinary research team Tech4Age started its long-term survey to evaluate the use of information and communication technology (ICT) by older adults () in Germany. This study focuses on the use of ICT devices and applications, the evaluation how these devices are operated in terms of ergonomic hand positions, the investigation of health information usage as well as technology affinity, health literacy and computer literacy. The first run of the Tech4Age long-term study was done by sending a paper-based questionnaire to 5,000 individuals older than 60 years randomly selected from the total German population and equally locally distributed within Germany. Responses were collected from N = 551 participants with a mean age of 69.17 years (SD = 5.787). The gender ratio of the sample is balanced, including 51.3% male and 48.7% female. Results provide descriptive insights into technology usage and knowledge about influencing factors. Older adults already use modern ICT on a large scale, for example to do online banking or for mobility reasons (navigation, booking tickets, etc.), but health-related ICT products and applications have been used less, mainly due to mistrust. Investigation of health information usage showed that doctors and pharmacists are the main sources older adults rely on. Two thirds of all participants were satisfied with general information they got about health. The evaluation of the ergonomic use of ICT devices revealed a common way of use, namely that a majority of older adults prefer to use their ICT devices in the case of a small display in portrait mode and in the case of larger displays in portrait as well as landscape mode. Touch input is always performed with a finger or the second hand, the one not holding the device. The article will present and discuss the results in detail.

    User-centered design in mobile human-robot cooperation: consideration of usability and situation awareness in GUI design for mobile robots at assembly workplaces
    (i-com: Vol. 22, No. 3, 2023) Colceriu, Christian; Theis, Sabine; Brell-Cokcan, Sigrid; Nitsch, Verena
    Mobile cobots can increase the potential for assembly work in industry. For human-friendly automation of cooperative assembly work, user-centered interfaces are necessary. The design process regarding user interfaces for mobile human-robot cooperation (HRC) shows large research gaps. In this article an exemplary approach is shown to design a graphical user interface (GUI) for mobile HRC at assembly workplaces. The design is based on a wireframe developed to support situation awareness. An interactive mockup is designed and evaluated. This is done in two iterations. In the first iteration, a user analysis is carried out using a quantitative survey with n = 31 participants to identify preferred input modalities and a qualitative survey with n = 11 participants that addresses touch interfaces. The interactive mockup is developed by implementing design recommendations of the usability standards ISO 9241 – 110, 112 and 13. A heuristic evaluation is conducted with n = 5 usability experts and the measurement of situation awareness with n = 30 end users. In the second iteration, findings from the preceding iteration are implemented in the GUI and a usability test with n = 20 end users is conducted. The process demonstrates a combination of methods that leads to high usability and situation awareness in mobile HRC.
