Interactive, Web-Based Food Portion Tutorial

这个项目的主要目的是开发和测试一个基于网络的程序的可行性，以提供食品部分教程的需求或通过互动培训模块。食物分量估计是饮食评估中相当大的误差来源，并且食物分量教程已被证明可以提高这些估计的准确性。不幸的是，这些教程的当前状态已被证明可以提高这些估计的准确性。不幸的是，这些教程的当前状态是非常“低技术”的，主要由各种份量的食物的图片或塑料模型组成，导致这些教程是劳动密集型的，传播不畅。第一阶段项目将开发一个基于网络的，先进的视频流，互动和自动化的食物部分教程（CFPT），可以很容易地被饮食研究人员，营养学家或普通消费者使用。在开发过程中，将与营养学家/研究人员和潜在最终用户进行可用性评价。将通过比较CFPT培训与未培训受试者在典型膳食后的食物部分估计来评价产品的可行性，随后将未培训队列暴露于CFPT按需特征，以确定暴露后其食物部分估计是否有所改善。拟议的商业应用：拟议产品的潜在市场包括所有出于任何原因监测其饮食和食物份量的个人，包括体重管理和各种医疗条件的饮食管理。虽然一般消费者应该发现CFPT有用，但该计划主要是为饮食研究人员和临床营养学家的需求而设计的，对他们来说，食物部分教程是任何不涉及食物部分称重的饮食评估的重要组成部分。市场营销的目标是谁的专业以及与商业饮食管理计划和先进功能的用户费用的阵列许可协议足以使这个项目在商业上可行。

The primary purpose of this project is to develop and test the feasibility of a web-based program to provide food portion tutorials on demand or via an interactive training module. Food portion estimation is a considerable source of error in a dietary assessments and food portion tutorials have been shown to improve the accuracy of these estimation. Unfortunately, the current state of these tutorials have been shown to improve the accuracy of these estimations. Unfortunately, the current state of these tutorials is remarkably "low-tech", consisting primarily of pictures or plastic models of foods in various portion sizes, causing these tutorials to be labor intensive and poorly disseminated. This Phase I project will develop a web-based, advanced video-streaming, interactive, and automated food portion tutorial (CFPT) that can be easily utilized by dietary researchers, nutritionists, or general consumers. Usability evaluations with nutritionists/researchers and with potential end users will be conducted during the development process. Feasibility of the product will be evaluated by comparing CFPT-trained vs. untrained subjects on food portion estimation following a typical meal, and subsequently exposing the untrained cohorts to the CFPT on-demand features to determine if their food portion estimation improves following exposure. PROPOSED COMMERCIAL APPLICATIONS: The potential market for the proposed product includes all individuals who monitor their diet and food portion size for any reason including weight management and dietary management of various medical conditions. Although general consumers should find the CFPT useful, the program is designed primary for he needs of dietary researchers and clinical nutritionists for whom food portion tutorials are an important component of any dietary assessment that does not involve weighing of food portions. Marketing which targets whose professions as well as licensing agreements with the array of commercial dietary management programs and user fees for advanced features are sufficient to make this project commercially viable.
