Retrofitting Existing 3D Objects with Surface-Conforming Capacitive Sensing
Andela Ilic, Junpeng Gao, Zhipeng Li +5
Augmenting the surface of 3D objects with capacitive sensing is challenging when their volumes cannot be modified. In this paper, we present a generative computational fabrication…
egoPPG: Heart Rate Estimation from Eye-Tracking Cameras in Egocentric Systems to Benefit Downstream Vision Tasks
Björn Braun, Rayan Armani, Manuel Meier +2
Egocentric vision systems aim to understand the spatial surroundings and the wearer's behavior inside it, including motions, activities, and interactions. We argue that egocentric…
BMAR: Barometric and Motion-based Alignment and Refinement for Offline Signal Synchronization across Devices
Manuel Meier, Christian Holz
A requirement of cross-modal signal processing is accurate signal alignment. Though simple on a single device, accurate signal synchronization becomes challenging as soon as multip…
Tri-Spectral PPG: Robust Reflective Photoplethysmography by Fusing Multiple Wavelengths for Cardiac Monitoring
Manuel Meier, Berken Utku Demirel, Christian Holz
Multi-channel photoplethysmography (PPG) sensors have found widespread adoption in wearable devices for monitoring cardiac health. Channels thereby serve different functions -- whe…
WildPPG: A Real-World PPG Dataset of Long Continuous Recordings
Manuel Meier, Berken Utku Demirel, Christian Holz
Reflective photoplethysmography (PPG) has become the default sensing technique in wearable devices to monitor cardiac activity via a person's heart rate (HR). However, PPG-based HR…
Robust Heart Rate Detection via Multi-Site Photoplethysmography
Manuel Meier, Christian Holz
Smartwatches have become popular for monitoring physiological parameters outside clinical settings. Using reflective photoplethysmography (PPG) sensors, such watches can non-invasi…
