Momentary Stressor Logging and Reflective Visualizations: Implications for Stress Management with Wearables Open
Commercial wearables from Fitbit, Garmin, and Whoop have recently introduced\nreal-time notifications based on detecting changes in physiological responses\nindicating potential stress. In this paper, we investigate how these new\ncapabili…

Dynamic models of stress-smoking responses based on high-frequency sensor data Open
Background and Aims: Self-reports indicate that stress increases risk for smoking; however, intensive data from sensors can provide a more nuanced understanding of stress in the moments leading up to and following smoking events. Identifyi…

Validation of K-Sense against indirect calorimetry and accelerometry Open
Purpose Considering the difficulty of accurately estimating energy expenditure (EE) in habitual physical activity (PA), efforts to improve estimation accuracy are well warranted. The aim of the study was, first, to validate the K-Sense EE …
