   CITRUS: Continuous Insight into Trusted Rhythms of Universal Signals

   Yi Wang

   MPhil thesis, HKUST(Guangzhou) · defending May 2026

   Three studies on continuous physiological sensing: ring PPG for cardiovascular vital signs across rest, daily activity, and running; an exploratory ECG↔PPG cross-modal waveform bridge; and a compact PSG-side sleep staging baseline. Connected by parameter-efficient state-space architectures.

   StoryEcho: A Generative Child-as-Actor Storytelling System for Picky-Eating Intervention

   Yanuo Zhou, Jun Fang, Yuntao Wang, Yi Wang, Nan Gao, Jinlei Liu, Yuanchun Shi

   ACM UIST 2026 · in submission

   A generative child-as-actor storytelling system for picky-eating intervention. The child appears as a persistent character whose real-world food-related behavior shapes story development; a between-group field study with 11 preschool families saw increased willingness to try low-preference foods and reduced parental feeding pressure.
