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。为了解 这种情况的病因，并制定有效的体重管理计划，饮食的准确采集 自由生活环境中的身体活动数据至关重要。目前，自我报告是主要的 数据采集方法，但不能准确反映真实的个人的真实习惯行为 生活因此，由于缺乏评估工具，无法提供公正客观的数据， 阻碍了肥胖症研究的进展我们提出了一种新的应用多媒体技术， 研究肥胖症。它将以电子纪事（或e-chronicle）这一功能强大的多媒体数据为基础 管理技术，它提供了一个容易访问的个人的电子存储器， 经验和日常事件。具体来说，我们将开发一个统一的传感器设备， 舒适，患者可轻松佩戴。该设备将由一组生理传感器组成， 微型摄像机记录的数据将被上传到一台功能强大的计算机， 将执行多媒体处理以去除视频中的人类外观并组织 利用电子纪事技术提供信息。饮食和活动相关事件将自动 提取、索引和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，承诺新的理解和有效的治疗 管理肥胖症的选择。 产品描述： 我们提出了一种新的应用多媒体技术的基础上，电子病历研究肥胖。 我们将开发由一组生理传感器和一个微型视频组成的统一传感器设备 摄像头采集现场数据。饮食和活动相关的事件将自动提取，索引， 组织，提供了一个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，以管理肥胖。
