A Unified Sensor System for Ubiquitous Assessment of Diet and Physical Activity

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，准确获取自由生活环境中的饮食和体力活动数据是至关重要的。目前，自我报告是数据获取的主要方式，但并不能准确反映个体在现实生活中的真实习惯行为。因此，缺乏评估工具来产生公正、客观的数据，大大阻碍了肥胖研究的进展。我们提出了一种多媒体技术在肥胖研究中的新应用。它将基于电子编年史(或电子编年史)，这是一种强大的多媒体数据管理技术，提供了一个易于访问的电子存储器，记录个人的经历和日常事件。具体地说，我们将开发一种统一的传感器设备，它具有美观的舒适性，患者可以轻松佩戴。该设备将由一组生理传感器和一个微型摄像机组成。记录的数据将被上传到一台功能强大的计算机，在那里将进行广泛的多媒体处理，以消除视频中的人类形象，并使用电子编年史技术组织信息。与饮食和活动相关的事件将被自动提取、索引并组织成易于访问的形式，为研究生活方式、行为和环境提供新的平台技术，承诺提供新的理解和有效的治疗选择来管理肥胖症。 我们提出了一种基于电子编年史的多媒体技术在肥胖研究中的新应用。我们将开发一套由一套生理传感器和一个微型摄像机组成的统一传感器设备来获取现场数据。与饮食和活动相关的事件将被自动提取、索引和组织，为研究生活方式、行为和环境提供新的平台技术，有望为管理肥胖提供新的理解和有效的治疗选择。

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.
