About the Webinar:
This talk presents an end to end framework that connects wearable and mobile sensing with agentic conversational health chatbots to enable continuous, real time personalization of health interactions. We describe how multimodal data from smartphones and wearables, including activity, sleep, location patterns, and ecological momentary inputs, are transformed into dynamic user models using platforms such as Centralive, ZotCare, and Personicle. These models inform when and how conversational agents engage with users, shaping dialogue strategies, emotional tone, and intervention content based on current and long term context. Building on this pipeline, we introduce openCHA, an open platform for building agentic health chatbots that integrate contextual reasoning, multimodal data fusion, and long horizon memory. We conclude by outlining challenges and opportunities in evaluating conversational health agents.
