The purpose of this study is to make use of visible light reflected mode
photoplethysmographic (PPG) imaging for heart rate (HR) monitoring via smartphones. The …

The paper presents a feasibility study for heart rate measurement using a digital camera to
perform health monitoring. The feasibility study investigates the reliability of the state of the …

Objective: Geriatric patients, especially those with dementia or in a delirious state, do not
accept conventional contact-based monitoring. Therefore, we propose to measure heart rate …

Because it is more convenient to measure photoplethysmography (PPG) than ECG, PPG is
supposed as a surrogate of ECG for heart rate variability (HRV) analysis. In this study, we …

This paper describes a method for estimation of heart rate (HR) and heart rate variability
(HRV) with accelerometers and gyroscopes. We denote this joint seismocardiography (SCG) …

Objective Heart rate monitoring using wrist type photoplethysmographic (PPG) signals is
getting popularity because of construction simplicity and low cost of wearable devices. The …

Heart rate variability (HRV) analysis has recently been incorporated into wearable device
application. The data source of HRV is the time series of heart beat intervals extracted from …

During the last decade, the world faced many pandemics, causing medical service providers
to struggle with diagnosing, following up with patients, keeping daily records, and …

Over the last few years, a rich amount of research has been conducted on remote vital sign
monitoring of the human body. Remote photoplethysmography (rPPG) is a camera-based …

Objective: Recent research indicates that facial epidermis color varies with the rhythm of
heat beats. It can be captured by consumer-level cameras and, astonishingly, be adopted to …
