Detecting Sleep Disruptions in Adolescents Using Context-Sensitive Ecological Momentary Assessment: A Feasibility Study

Published in Pervasive Computing Technologies for Healthcare. PervasiveHealth 2024. Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering., 2024

In this work we explored the feasibility of using a context-sensitive EMA system to understand causes of sleep disruptions in adolescents based on sensor data from a smartwatch and environmental sensors.

Feasibility and Utility of Multimodal Micro Ecological Momentary Assessment on a Smartwatch

Published in Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems, 2025

In this work, we combine two input modalities to create a multimodal-μ EMA system, allowing participants to choose between speech or touch input to self-report physical activity and posture information. This paper reports on feasibility and usability of the multimodal system based on field testing with 20 participants.
