Soli-enabled Noncontact Heart Rate Detection for Sleep and Meditation Tracking
Luzhou Xu, Jaime Lien, Haiguang Li +17
Heart rate (HR) is a crucial physiological signal that can be used to monitor health and fitness. Traditional methods for measuring HR require wearable devices, which can be inconv…
Passive Heart Rate Monitoring During Smartphone Use in Everyday Life
Shun Liao, Paolo Di Achille, Jiang Wu +15
Resting heart rate (RHR) is an important biomarker of cardiovascular health and mortality, but tracking it longitudinally generally requires a wearable device, limiting its availab…
WavesFM: Hierarchical Representation Learning for Longitudinal Wearable Sensor Waveforms
Peng Cao, Zhijian Yang, Tennison Liu +17
Wearable sensors enable the continuous acquisition of high-resolution physiological waveforms, such as photoplethysmography and accelerometry, under free-living conditions. However…
Towards a General Intelligence and Interface for Wearable Health Data
Girish Narayanswamy, Maxwell A. Xu, A. Ali Heydari +37
While ubiquitous wearable sensors capture a wealth of behavioral and physiological information, effectively transforming these signals into personalized health insights is challeng…
Smartphone monitoring of smiling as a behavioral proxy of well-being in everyday life
Ming-Zher Poh, Shun Liao, Marco Andreetto +10
Subjective well-being is a cornerstone of individual and societal health, yet its scientific measurement has traditionally relied on self-report methods prone to recall bias and hi…
