Reassessing the Feasibility of PPG-Based Non-Invasive Blood Glucose Level Estimation
Supraja Ramesh, Markus Neufeld, Michael Küttner +2
Non-invasive blood glucose level (BGL) estimation from photoplethysmography (PPG) holds great promise for wearable health monitoring, but results across studies are hard to compare…
EarResp-ANS : Audio-Based On-Device Respiration Rate Estimation on Earphones with Adaptive Noise Suppression
Michael Küttner, Valeria Zitz, Supraja Ramesh +2
Respiratory rate (RR) is a key vital sign for clinical assessment and mental well-being, yet it is rarely monitored in everyday life due to the lack of unobtrusive sensing technolo…
CHOMP: Multimodal Chewing Side Detection with Earphones
Jonas Hummel, Maximilian Burzer, Felix Schlotter +6
Chewing side preference (CSP) has been identified both as a risk factor for temporomandibular disorders (TMD) and behavioral manifestation. Despite TMDs affecting roughly one third…
EarXplore: An Open Research Database on Earable Interaction
Jonas Hummel, Tobias Röddiger, Valeria Zitz +6
Interaction with sensor-augmented earphones, referred to as earables or hearables, represents a major area of earable research. Proximate to the head and reachable by hand, earable…
UltrasonicSpheres: Localized, Multi-Channel Sound Spheres Using Off-the-Shelf Speakers and Earables
Michael Küttner, Valeria Zitz, Kathrin Gerling +2
We present a demo of UltrasonicSpheres, a novel system for location-specific audio delivery using wearable earphones that decode ultrasonic signals into audible sound. Unlike conve…
Heatables: Effects of Infrared-LED-Induced Ear Heating on Thermal Perception, Comfort, and Cognitive Performance
Valeria Zitz, Michael Küttner, Jonas Hummel +3
Maintaining thermal comfort in shared indoor environments remains challenging, as centralized HVAC systems are slow to adapt and standardized to group norms. Cold exposure not only…
