Abstract

Introduction

Staying hydrated is an essential aspect of good health for people of all ages. Tracking fluid intake is important to ensure proper hydration and prompt users to drink as needed. Previous literature has attempted to measure the amount of fluid consumption, often using wearables or sensors embedded in containers.

Objective

In this paper, we introduce a novel vision-based method to estimate the amount of fluid consumed.

Methods

We trained different 3D Convolutional Neural Networks on data from 8 participants drinking from multiple containers and engaging in other activities in a simulated home environment.

Results

We show that it is possible to perform both drinking detection and volume intake estimation in a single algorithm with a Mean Absolute Percent Error (MAPE) of 28.5% and a Mean Percent Error (MPE) of 2.6% with 10-Fold and a MAPE of 42.4% and MPE of 25.4% for Leave-One-Subject-Out cross validation.

Conclusion

This shows that using video inputs does have the potential to detect and estimate the amount of fluid consumed throughout the day.

用一种新的基于视觉的方法估计液体摄入量

对所有年龄段的人来说，保持水分是保持健康的一个重要方面。跟踪液体摄入量对于确保适当的水合作用和提示用户根据需要喝水是很重要的。以前的文献试图测量液体消耗量，通常使用可穿戴设备或嵌入容器中的传感器。目的介绍一种基于视觉的液体摄取量估算方法。方法对8名被试在模拟的家庭环境中从多个容器中饮水和从事其他活动的数据进行三维卷积神经网络训练。结果表明，在一个算法中可以同时进行饮酒检测和体积摄入估计，平均绝对百分比误差(MAPE)为28.5%，平均百分比误差(MPE)为2.6%，10-Fold, MAPE为42.4%，MPE为25.4%。这表明，使用视频输入确实有可能检测和估计全天消耗的液体量。
