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。为了了解找出这种病症的病因并制定有效的体重管理方案，准确获取饮食自由生活环境中的体力活动数据至关重要。目前，自我报告是主要方式数据采集方法，但并不能准确反映现实中个体的真实习惯行为生活。因此，缺乏产生公正、客观数据的评估工具已严重影响阻碍了肥胖研究的进展。我们提出了一种多媒体技术的新颖应用研究肥胖。它将基于电子编年史（或e-chronicle），一种强大的多媒体数据管理技术，提供个人易于访问的电子存储器经历和日常事件。具体来说，我们将开发一种统一的传感器设备，该设备具有美观性舒适且可以方便患者佩戴。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，其中广泛将进行多媒体处理以消除视频中的人物并组织使用电子编年史技术的信息。饮食和活动相关事件将自动提取、索引并组织成易于访问的形式，提供了一种新的平台技术研究生活方式、行为和环境，以提供新的理解和有效的治疗控制肥胖的选择。描述：我们提出了一种基于电子记录的多媒体技术的新颖应用来研究肥胖。我们将开发一个统一的传感器设备，由一组生理传感器和一个微型视频组成相机来获取现场数据。饮食和活动相关事件将被自动提取、索引和组织起来，提供了一个新的平台技术来研究生活方式、行为和环境，有望为控制肥胖提供新的认识和有效的治疗选择。
