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…
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…
Nightbeat: Heart Rate Estimation From a Wrist-Worn Accelerometer During Sleep
Max Moebus, Lars Hauptmann, Nicolas Kopp +3
Today's fitness bands and smartwatches typically track heart rates (HR) using optical sensors. Large behavioral studies such as the UK Biobank use activity trackers without such op…
Accurately Tracking Relative Positions of Moving Trackers based on UWB Ranging and Inertial Sensing without Anchors
Rayan Armani, Christian Holz
We present a tracking system for relative positioning that can operate on entirely moving tracking nodes without the need for stationary anchors. Each node embeds a 9-DOF magnetic…
LLM-for-X: Application-agnostic Integration of Large Language Models to Support Personal Writing Workflows
Lukas Teufelberger, Xintong Liu, Zhipeng Li +2
To enhance productivity and to streamline workflows, there is a growing trend to embed large language model (LLM) functionality into applications, from browser-based web apps to na…
