Towards Better Health Conversations: The Benefits of Context-seeking

Navigating health questions can be daunting in the modern information landscape. Large language models (LLMs) may provide tailored, accessible information, but also risk being inaccurate, biased or misleading. We present insights from 4 mixed-methods studies (total N=163), examining how people interact with LLMs for their own health questions. Qualitative studies revealed the importance of context-seeking in conversational AIs to elicit specific details a person may not volunteer or know to share. Context-seeking by LLMs was valued by participants, even if it meant deferring an answer for several turns. Incorporating these insights, we developed a "Wayfinding AI" to proactively solicit context. In a randomized, blinded study, participants rated the Wayfinding AI as more helpful, relevant, and tailored to their concerns compared to a baseline AI. These results demonstrate the strong impact of proactive context-seeking on conversational dynamics, and suggest design patterns for conversational AI to help navigate health topics.

Towards an AI-Augmented Textbook

Textbooks are a cornerstone of education, but they have a fundamental limitation: they are a one-size-fits-all medium. Any new material or alternative representation requires arduous human effort, so that textbooks cannot be adapted in a scalable manner. We present an approach for transforming and augmenting textbooks using generative AI, adding layers of multiple representations and personalization while maintaining content integrity and quality. We refer to the system built with this approach as Learn Your Way. We report pedagogical evaluations of the different transformations and augmentations, and present the results of a a randomized control trial, highlighting the advantages of learning with Learn Your Way over regular textbook usage.

An Exploratory Study of Health Habit Formation Through Gamification

Promotion of healthy habits help maintain and improve people health, reduce disease risks, and manage chronic illness. Regular healthy activities like walking, exercising, healthy eating, drinking water or taking medication on time require forming the new habits. Gamification techniques are promising in promoting healthy behaviors and delivering health promotion information. However, using gaming elements such as badges, leader boards, health-related challenges in mobile applications to motivate and engage people to change health behavior is quite new. In this exploratory study, we aimed to assess how game mechanics and dynamics influence formation of a habit through the mobile application. Results indicate the different level of user engagement depending on the presence of gamification elements and suggest that there is value in adding game elements to the user experience.

Medication non adherence: finding solutions through design thinking approach

Medical non-adherence increasingly is recognized as a major medical health problem. Approximately 50% of patients do not take their medications as prescribed and such poor adherence has been shown to result in complications, death, and increased health care costs. This problem becomes even more significant for patients with chronic illness and those who need to take medications lifetime, like transplant patients. Studies show that one-half of rejection episodes and 15% of graft losses happen due to immunosuppression medications non-adherence. This article explores factors that have an impact on non-compliant behavior among transplant patients: patient factors, illness factor, therapeutic regimen factors. Using user-centered design thinking approach a set of hypotheses are defined and discussed strategies to enhance adherence by using mobile technology and gamification techniques.
