DESCRIPTION (provided by applicant): 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.

描述（由申请人提供）： 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，必须准确获取自由生活环境中的饮食和体育活动数据。当前，自我报告是数据获取的主要方法，但并不能准确反映个人在现实生活中的真实习惯行为。结果，缺乏产生无偏见的客观数据的评估工具严重阻碍了肥胖研究的进步。我们提出了多媒体技术研究肥胖症的新应用。它将基于电子纪事（或电子奇思堡），这是一种强大的多媒体数据管理技术，可为个人的体验和日常事件提供易于访问的电子记忆。具体而言，我们将开发一种统一的传感器设备，该设备在化妆上令人愉悦，并且很容易被患者佩戴。该设备将由一组生理传感器和微型摄像机组成。记录的数据将上传到一台功能强大的计算机，其中将进行广泛的多媒体处理以删除视频中的人类外观，并使用E-Chronicle技术组织信息。饮食和活动与活动相关的事件将自动提取，索引和组织为易于访问的形式，从而提供一种新的平台技术来研究生活方式，行为和环境，有望提供新的理解和有效治疗方案来管理肥胖。 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摄像机组成的统一传感器设备，以获取现场数据。将自动提取，索引和组织与饮食和活动相关的事件，提供一种新的平台技术来研究生活方式，行为和环境，有望提供新的理解和有效治疗方案来管理肥胖症。
