论文摘要
可穿戴电子设备通常用于根据心率测量来估算用户的能量消耗。尽管心率是高强度下卡路里消耗的良好预测指标，但在低强度水平下它的精确度较低，这在估计每日净能量消耗时会转化为不准确的结果。在这项研究中，通过热通量测量（一种直接量热法的形式）增强心率测量。对一组15人进行的体育锻炼测试表明，与心率信息和用户的重要背景参数结合使用时，热通量测量可以显着提高卡路里消耗估计的准确性。
Wearable electronics are often used for estimating the energy expenditure of the user based on heart rate measurement. While heart rate is a good predictor of calorie consumption at high intensities, it is less precise at low intensity levels, which translates into inaccurate results when estimating daily net energy expenditure. In this study, heart rate measurement was augmented with heat flux measurement, a form of direct calorimetry. A physical exercise test on a group of 15 people showed that heat flux measurement can significantly improve the accuracy of calorie consumption estimates when used in conjunction with heart rate information and vital background parameters of the user.
