| 2025 | Improving Online Communities for Stigmatized Healthcare: Countering In-Group Microaggressions and Fostering Supportive ConnectionsabstractWomen face significant challenges in seeking support for sexual and reproductive health (SRH) due to cultural taboos and microaggressions, even within supposedly safe online spaces. This study focuses on unmarried South Korean women who encounter these difficulties and often risk detrimental health outcomes by avoiding timely care. To investigate how to create safer and more supportive spaces for these women, we designed a 9-week study using the Asynchronous Remote Communities method for 26 unmarried Korean women participants. We created structured and unstructured activities to encourage sharing SRH narratives, which led to increased mutual support and understanding among participants. Additionally, we designed educational and reflective interventions that helped participants recognize the nuances and harms of microaggressions. This increased awareness promoted self-reflection and supportive actions among participants. Our approach demonstrates the potential to create supportive, reflective online spaces for people from marginalized communities who face stigmatized healthcare challenges. We hope our research inspires the development of more inclusive online spaces, driving positive social change in stigmatized healthcare support.

| 2024 | MigraineTracker: Examining Patient Experiences with Goal-Directed Self-Tracking for a Chronic Health ConditionabstractSelf-tracking and personal informatics offer important potential in chronic condition management, but such potential is often undermined by difficulty in aligning self-tracking tools to an individual's goals. Informed by prior proposals of goal-directed tracking, we designed and developed MigraineTracker, a prototype app that emphasizes explicit expression of goals for migraine-related self-tracking. We then examined migraine patient experiences in a deployment study for an average of 12+ months, including a total of 50 interview sessions with 10 patients working with 3 different clinicians. Patients were able to express multiple types of goals, evolve their goals over time, align tracking to their goals, personalize their tracking, reflect in the context of their goals, and gain insights that enabled understanding, communication, and action. We discuss how these results highlight the importance of accounting for distinct and concurrent goals in personal informatics together with implications for the design of future goal-directed personal informatics tools.

| 2024 | Exploring the Extent of Usability for Augmented Profile Interfaces in Enhancing Conversation ExperiencesabstractAbstract In this study, we investigated how to design a usable augmented reality (AR) profile conversation assistant focusing on how and which information leads to enhanced conversation experience and satisfaction. We drew on usability practices including user need interviews, information disposition sessions and an experiment comparing the conversation experiences between AR profile usage and non-usage. We provide insights into how to design a user interface that can enhance users' conversation experience and satisfaction compared to existing interfaces, especially in terms of type, quantity and placement of information on the AR profile. The three main design insights are to (1) limit the topics to personal information, recent events, preferences and hobbies; (2) use a text-based card format with emojis and make a clear distinction between preferred and not preferred topics through font size and placement difference; and (3) limit the number of information provision pages to less than four pages; however, we were not able to resolve the problem of the guilt and artificiality users feel in acquiring information about others from the AR profile. Thus, to resolve this problem, we suggest shifting our paradigm from a techno-solutionist perspective to breaking the illusion of the omnipotence of technology.

| 2023 | "You Can See the Connections": Facilitating Visualization of Care Priorities in People Living with Multiple Chronic Health ConditionsabstractIndividuals with multiple chronic health conditions (MCC) often face an overwhelming set of self-management work, resulting in a need to set care priorities. Yet, much self-management work is invisible to healthcare providers. This study aimed to understand how to support the development and sharing of connections between personal values and self-management tasks through the facilitated use of an interactive visualization system: Conversation Canvas. We conducted a field study with 13 participants with MCC, 3 caregivers, and 7 primary care providers in Washington State. Analysis of interviews with MCC participants showed that developing visualizations of connections between personal values, self-management tasks, and health conditions helped individuals make sense of connections relevant to their health and wellbeing, recognize a road map of central issues and their impacts, feel respected and understood, share priorities with providers, and support value-aligned changes. These findings demonstrated potential for the guided process and visualization to support priorities-aligned care. Hyeyoung Ryu, Andrew B. L. Berry, Catherine Lim, Andrea L.

| 2022 | Microaggression clues from social media: revealing and counteracting the suppression of women's health careabstractOBJECTIVE: The purpose of this study was to demonstrate how analyzing social media posts can uncover microaggressions and generate new cultural insights. We explore why Korean women hesitate to seek recommended gynecological care and how microaggressions visible in social media reveal insights for counteracting such harmful messaging. MATERIALS AND METHODS: We scraped the posts and responses on social media related to unmarried women's uncomfortableness or unpleasantness in receiving gynecological care. We conducted content analyses of the posts and responses with the microaggression framework to identify both the types of microaggressions occurring within and outside the clinic as well as the responsible perpetrators. With an open-coding and subsequent deductive coding approach, we further investigated the socio-cultural context for receiving gynecological care as an unmarried woman in South Korea. RESULTS: Our analysis uncovered that mothers, male partners, and superficially supportive social media responders contribute to pre- and post-visit microaggressions toward unmarried women seeking gynecological care whereas healthcare providers contribute to only mid-visit microaggressions. We also exposed how social media was not only revealing but also reinforcing the suppression of women's health care. DISCUSSION: Mid-visit microaggressions are currently addressed by cultural competence education, but pre- and post-visit microaggressions are overlooked. We uncover the gaps in current practices of informatics and public health methods and suggest ways to counteract online and offline microaggressions. CONCLUSIONS: Social media provides valuable information about the cultural context of health care and should be used as a source of insights for targeted interventions to improve health care, in this case for unmarried Korean women.

| 2020 | Simple and Steady Interactions Win the Healthy Mentality: Designing a Chatbot Service for the ElderlyabstractAlthough suicide among older adults is increasing in severity in the aging among South Koreans, older adult depression and anxiety, which are two crucial factors affecting suicide in this population, are not adequately addressed by the status quo. Existing products and services emphasize physical needs; however, they still lack a user-oriented approach. Moreover, offers for mental health care are costly and exclude potential users from the development process, thus inhibiting older adults from having better access to such services. To address this problem, we designed and developed a mental health care chatbot, Yeonheebot, to decrease anxiety and depression among older adults. Yeonheebot initiates conversations regarding daily care for the well-being of older adults and provides features related to their interests as initiatives for using the mental health care chatbot. To examine whether a short-term, yet repeating conversation with the agent could help reduce anxiety and depression among older adults, we conducted a 2-week field study with 25 users. The results indicate that the constant use of Yeonheebot decreased the levels of anxiety and depression by 36% and 18%, respectively. Our research implies that simple and repeated interactions could help Korean older adults cope with anxiety and depression. Hyeyoung Ryu, Sooan Han, Keeheon Lee, Younah Kang |
