Monitoring of Heart and Breathing Rates using Dual Cameras on a Smartphone

This data correspond to a manuscript of Plos One (ID: PONE-D-15-39290).Data were collected from N=11 healthy non-smokers (2 females and 9 males) between 20 and 40 years old, who were dressed in striped, spotted, or plain clothes. All subjects were instructed to breathe at a metronome rate according to a timed beeping sound programmed at a chosen frequency. The metronome breathing rate was done to test wide dynamics range of breathing rates. Each subject was asked to inhale with each beep sound followed by exhalation before the next beep sound occurred. The data were collected for breathing frequencies ranging from 0.1 to 0.5 Hz at increments of 0.1 Hz, 1 Hz, and spontaneous breathing. Prior to data collection, all subjects were acclimated to different metronome breathing rates. Two minutes of ECG, chest and abdominal movements from the front camera, and finger pulse signals from the rear camera data, were collected for each breathing maneuver, for each subject.本数据集对应《公共科学图书馆·综合》（PLOS ONE）的一篇手稿，编号为PONE-D-15-39290。数据采集自样本量N=11的健康非吸烟者（2名女性、9名男性），年龄介于20至40岁，受试者身着条纹、斑点或素色衣物。所有受试者被要求按照以选定频率编程的定时蜂鸣声的节拍器速率进行呼吸。设置节拍器呼吸速率的目的是测试呼吸频率的宽动态范围。每位受试者需在每次蜂鸣声响起时吸气，并在下一次蜂鸣声响起前完成呼气。本次数据采集涵盖0.1至0.5 Hz（步长0.1 Hz）、1 Hz以及自主呼吸的呼吸频率。在正式采集数据前，所有受试者均已适应不同的节拍器呼吸频率。针对每位受试者的每种呼吸操作，均采集了2分钟的心电图（ECG）、前置摄像头采集的胸部与腹部运动信号，以及后置摄像头采集的指尖脉搏信号。
