Coughing is a common symptom of several respiratory diseases. The sound and type of
cough are useful features to consider when diagnosing a disease. Respiratory infections …

For COVID-19, the need for robust, inexpensive, and accessible screening becomes critical.
Even though symptoms present differently, cough is still taken as one of the primary …

The scarcity of training data available for IMUs in wearables poses a serious challenge for
IMU-based American Sign Language (ASL) recognition. In this paper, we ask the following …

A mask serves as a simple external barrier that protects humans from infectious particles
from poor air conditions in the surrounding environment. As an important personal protective …

Breathing biomarkers, such as breathing rate, fractional inspiratory time, and inhalation-
exhalation ratio, are vital for monitoring the user's health and well-being. Accurate estimation …

Respiratory rate (RR) is a significant indicator of health conditions. Remote contactless
measurement of RR is gaining popularity with recent respiratory tract infection awareness …

This paper presents algorithms to improve the estimation of heart rate (HR) and heart rate
variability (HRV) from smartphone video. The remote photoplethysmogram (rPPG) signals …

Remote photoplethysmography (PPG) estimates vital signs by measuring changes in the
reflected light from the human skin. Compared to traditional PPG techniques, remote PPG …

The synchronization of wearable devices in distributed, multi-device systems is a persistent
challenge. Particularly machine learning approaches suffer from the devices' inaccurate …

Sensor networks require a high degree of synchronization in order to produce a stream of
data useful for further purposes. Examples of time misalignment manifest as undesired …
