Accuracy of the Apple Watch 4 to Measure Heart Rate in Patients with Atrial Fibrillation
Wearable wrist-monitors offer an unobtrusive way to acquire heart rate data in an efficient manner. Previous work in this field has focused on studying healthy subjects during exercise but has yet to assess the efficacy of these devices in patients... Read more

Effects of Virtual Reality and Augmented Reality on Induced Anxiety
     To explore the effects of virtual reality (VR) and augmented reality (AR) in the treatment of claustrophobia, the potential effects of VR and AR on induced anxiety were investigated in this paper. During the experiment, 34 subjects were randomly selected... Read more

Algorithms for monitoring heart rate and respiratory rate from the video of a user’s face
  Abstract Smartphone cameras can measure heart rate (HR) by detecting pulsatile photoplethysmographic (iPPG) signals from post-processing the video of a subject’s face. The iPPG signal is often derived from variations in the intensity of the green channel as shown by Poh... Read more

An Ear-Worn Vital Signs Monitor
  Cardiovascular disease (CVD) affects over one third of the U.S. population and is the current leading cause of death. Many key cardiovascular parameters such as the heart rate, stroke volume, pre-ejection period (PEP), and pulse transit time (PTT) have valuable... Read more

Heart Rate Detection during Sleep Using the Flexible RF Resonator and Injection-Locked PLL Sensor
A novel non-intrusive technology for wrist pulse detection system has been developed and proposed for sleep monitoring using three types of radio frequency (RF) sensors. The three types of RF sensors for heart rate measurement on wrist, were the flexible... Read more

Personalization of Energy Expenditure Estimation in Free Living Using Topic Models
We introduce an approach to personalize energy expenditure (EE) estimates in free living. First we use Topic Models (TM) to discover activity composites from recognized activity primitives and stay regions in daily living data. Subsequently, we determine activity composites that... Read more
