项目摘要

Obesity is associated with a large variety of genetic and environmental factors. In order to understand the etiology of this condition and develop effective weight management programs, accurate acquisition of diet and physical activity data in free-living environment is essential. Currently, self-reporting is the primary method for data acquisition, but does not accurately reflect the true habitual behavior of individuals in real life. As a result, the lack of assessment tools to produce unbiased, objective data has significantly hampered the progress of obesity research. We propose a novel application of multimedia technology to study obesity. It will be based on electronic chronicle (or e-chronicle), a powerful multimedia data management technology which provides an easily accessible electronic memory of individual's experience and daily events. Specifically, we will develop a unified sensor device which is cosmetically pleasant and can be easily worn by patients. This device will consist of a set of physiological sensors and a miniature video camera. The data recorded will be uploaded to a powerful computer where extensive multimedia processing will be performed to remove human appearances in the video and organize information using the e-chronicle technology. Diet and activity related events will be automatically extracted, indexed, and organized into an easily accessible form, providing a new platform technology to study lifestyle, behavior, and environment that promises new understanding and effective treatment option to manage obesity.

肥胖与多种遗传和环境因素有关。为了了解这种情况的病因并制定有效的体重管理计划，准确获取饮食自由生活环境中的体育活动数据至关重要。目前，自我报告是主要的数据获取的方法，但不能准确地反映出个人的真实习惯行为生活。结果，缺乏产生公正，客观数据的评估工具显着阻碍了肥胖研究的进步。我们建议多媒体技术的新颖应用研究肥胖。它将基于电子纪事（或电子奇思堡），这是一个强大的多媒体数据管理技术，提供了易于访问的个人的电子记忆经验和日常活动。具体而言，我们将开发一个统一的传感器设备宜人，病人很容易穿。该设备将由一组生理传感器和微型摄像机。记录的数据将上传到功能强大的计算机上将执行多媒体处理以删除视频中的人类外观并组织使用电子智能技术的信息。饮食和活动相关事件将自动提取，索引和组织为易于访问的形式，为新的平台技术提供学习新理解和有效治疗的生活方式，行为和环境管理肥胖的选项。描述：我们提出了基于电子纪事的多媒体技术的新型应用来研究肥胖症。我们将开发一个由一组生理传感器和微型视频组成的统一传感器设备相机以获取现场数据。饮食和活动相关事件将自动提取，索引，并有组织，提供了一种新的平台技术来研究生活方式，行为和环境承诺新的理解和有效的治疗选择来管理肥胖症。
