Abstract

Electronic sensors and various digital devices have been quite successful in improving collection of physical activity data in a pervasive manner, and we believe that advances in dietary assessment can be achieved using similar strategies. Dietary assessment is a critical yet understudied component within the domain of recent advances in electronic health records management. The design of a system for real-time recording of food intake requires considerable research to optimize both system characteristics and data collection procedures, and rigorous validation to confirm its superiority compared to paper-based methods for self-report. We propose to demonstrate a functional prototype of a Dietary Data Recording System (DDRS), which consists of an electronic data collection device and the software and protocols necessary to support data capture and calculation of nutrient intake. A key innovative feature of the DDRS is the use of a video camera and a laser-generated grid of distances to food surfaces, which allows calculation of food volume. This prototype system is a first step in designing an overall framework to support a realistic and rigorous evaluation of whether real-time, electronic collection of dietary data is feasible, acceptable and valid for better health data management. Components demonstrated include a real-time data collection application based on the Google Android OS, a stream based data transfer and on the fly evaluation.
一个普遍的饮食数据记录系统
电子传感器和各种数字设备已经非常成功地以一种普遍的方式改善了身体活动数据的收集,我们相信,在饮食评估方面的进步可以通过类似的策略来实现。膳食评估是电子健康记录管理领域最新进展中一个关键但尚未得到充分研究的组成部分。设计一个实时记录食物摄入量的系统需要大量的研究来优化系统特性和数据收集程序,并需要严格的验证来确认其相对于基于纸张的自我报告方法的优越性。我们建议展示一个膳食数据记录系统(DDRS)的功能原型,该系统由一个电子数据收集设备和支持数据捕获和营养摄入量计算所需的软件和协议组成。DDRS的一个关键创新功能是使用摄像机和激光生成的食物表面距离网格,可以计算食物体积。该原型系统是设计总体框架的第一步,该框架支持对膳食数据的实时电子收集是否可行、可接受和有效进行现实和严格的评估,以更好地管理健康数据。演示的组件包括基于Google Android操作系统的实时数据收集应用程序,基于流的数据传输和动态评估。
