    CyMe [si:][mi:]: Personalized and Seamless Menstrual Health Tracking
    (Mensch und Computer 2024 - Workshopband, 2024) Principe, Marinja; Stebler, Debs; Sou, Davinny; Kowatsch, Tobias; Nißen, Marcia
    Menstruating individuals experience various physiological and psychological changes throughout their reproductive lives and each menstrual cycle. Although numerous menstrual health tracking apps, exist, there is limited research on the impact of customization options and personalized visualizations of menstrual cycle data and associated symptoms on user experiences. Furthermore, evidence on the long-term effects of these features on menstrual health awareness and literacy is sparse. This demo contribution presents “CyMe” [siː][miː], a menstrual health tracking prototype designed to support the different needs of individuals while focusing on a simple yet effective reporting approach integrating smartphone and smartwatch data. CyMe focuses on customization options for seamless data reporting and personalized visualizations, enabling users to focus on their individual menstrual health challenges. CyMe also aims to enhance the user experience by giving the user agency over the look and feel of the application, allowing them to adjust self-reporting options, colors, and reminders and connect different sensor devices. This approach should support the wide range of needs of menstruating individuals to be seen and allow users to get actionable insights into their menstrual health.

    Demonstrating GRACE: Our Embodied Voice Assistant Providing Cognitive Interventions
    (Mensch und Computer 2024 - Workshopband, 2024) Vinay, Rasita; Tommila, Nora C.; Schlögl, Mathias; Klöppel, Stefan; Biller-Andorno, Nikola; Kowatsch, Tobias
    Our demo describes the development and interaction of our first prototype of GRACE, an embodied voice assistant. GRACE was designed to provide voice-based cognitive interventions to its users, and was first piloted with healthy adults in its current version. The body of GRACE, which was 3D printed, encases the internal components such as the Raspberry Pi, reSpeaker microphone, an AMOLED screen, and a bluetooth speaker. We utilized an open-source robotics platform and their simulation software for executing the script and commands for the voice interactions. A text-to-speech voice from ElevenLabs was used as the voice for GRACE. We were able to develop and design four activities, including two cognitive interactions based on cognitive stimulation therapy. The interaction consisted of an introductory warm-up activity, two cognitive interventions, and a concluding activity.

    A design and evaluation framework for digital health interventions
    (it - Information Technology: Vol. 61, No. 5-6, 2019) Kowatsch, Tobias; Otto, Lena; Harperink, Samira; Cotti, Amanda; Schlieter, Hannes
    Digital health interventions (DHIs) have the potential to help the growing number of chronic disease patients better manage their everyday lives. However, guidelines for the systematic development of DHIs are still scarce. The current work has, therefore, the objective to propose a framework for the design and evaluation of DHIs (DEDHI). The DEDHI framework is meant to support both researchers and practitioners alike from early conceptual DHI models to large-scale implementations of DHIs in the healthcare market.

    Digital Female Health: Advancing Women-Centric Human-Computer Interaction Research
    (Mensch und Computer 2024 - Workshopband, 2024) Nißen, Marcia; Sou, Davinny; Kowatsch, Tobias
    Hormonal changes in the female body function much like an underlying operating system on a computer – constantly running in the background, influencing every aspect of operation, often unnoticed yet crucially impactful. Hormonal dynamics over the life course such as those associated with the menstrual cycle, pregnancy, or the menopausal transition orchestrate a myriad of physiological and psychological processes that shape women’s health , well-being, and behavior, influencing everything from cognitive function and emotional regulation to pain perception, energy levels, and mood, which can also significantly impact individuals’ behavior and thus their interactions with digital health technologies (DHTs). This position paper discusses the need for systematically integrating female-specific data into human-computer interaction (HCI) research in general and the development of DHTs in particular. It further discusses some of the challenges associated with collecting such data and argues for the methodological standardization of sex- and gender-sensitive research methodologies in HCI to enhance the inclusivity and accuracy of DHTs.

    GRACE: Towards an Embodied Voice Assistant for Improving Quality of Life by Leveraging Elements of Cognitive Stimulation Therapy
    (Proceedings of Mensch und Computer 2024, 2024) Vinay, Rasita; Tommila, Nora Camilla; Schlögl, Mathias; Klöppel, Stefan; Biller-Andorno, Nikola; Kowatsch, Tobias
    Dementia is one the leading causes of death globally. Although currently no cure exists, there are multiple interventions aimed at improving the quality of life of people with dementia by leveraging elements of cognitive stimulation therapy. This work is the first of a several-year research agenda that investigates the feasibility and effectiveness of embodied voice assistants to deliver such interventions. We describe the development of the GRACE prototype based on an open-source social robotics platform. We expand its functionality by adding two intervention components of cognitive stimulation therapy and making the robot more interactive by integrating a public large language model. We also conduct a first evaluation with 11 healthy participants who assess perceived technology characteristics including working alliance, an important relationship quality, which is robustly linked to treatment success. Results indicate that GRACE was perceived positively. We conclude this short paper with suggestions for improvement and outline future work.

    Please CyMe: Towards Enhancing Menstrual Health Awareness through Customization and Personalized Visualization in a Menstrual Health App
    (Proceedings of Mensch und Computer 2024, 2024) Sou, Davinny; Stebler, Debs; Principe, Marinja; Kowatsch, Tobias; Nißen, Marcia
    Menstruating individuals experience various physiological and psychological changes throughout their reproductive lives and each menstrual cycle (MC). Although numerous digital health technologies (DHTs), such as menstrual health (MH) tracking apps, exist, there is limited research on how customization options and personalized visualizations of MC data and associated symptoms impact user experiences with these technologies. Furthermore, evidence on the long-term effects of these features on MH awareness and literacy is sparse. Therefore, the goals of this research are twofold: First, we examine users’ current experiences and needs regarding MH (technologies) in an online survey with 272 participants, highlighting a discrepancy between individuals’ perceptions and their actual understanding of their MH and its impact on their well-being. Yet, participants showed a strong interest in understanding and managing their MH through DHTs. Desired improvements in MH technologies include more accurate prediction of MC phases, as well as more comprehensive insights and support in managing MH through customization and personalization. Second, to examine how customization options and personalized visualizations of MH data affect user engagement and improve MH awareness and literacy in a longitudinal study with up to 70 participants, we are currently developing the MH study app CyMe [si:][mi:].
