Video-based photoplethysmography (VPG) is an optical method that allows the remote acquisition of pulsatile signals using common video cameras. The underlying principle is similar to regular photoplethysmography (PPG) where backscattered light from superficial skin layers, which is modulated by physiological processes, is captured and converted into signals. PPG functions with light in the visible and near-infrared spectrum. In contrast to PPG, VPG relies on visible light as captured by RGB cameras without the need for a dedicated light source, but using ambient light instead.
The purpose of this research study is to verify the performance, accuracy, and usability of an APP (HealthKam AFib) developed by VPG Medical Inc. We will study the accuracy of this APP installed on a tablet device and a laptop in reference to FDA-cleared measurement technology.
