DESCRIPTION (provided by applicant): Wearable eButton for Evaluation of Energy Balance with Environmental Context and Behavior Overweight and obesity have become a wide spread epidemic affecting more than 60% of the population in the United States. A recent study indicates that the estimated direct and indirect costs of obesity to the U.S. economy are at least $215 billion annually. In the battle against obesity and related diseases, both the research and clinical communities require an accurate tool to measure people's energy intake and expenditure in real life. However, presently, the most utilized tool is still a questionnaire which is subjective and often inaccurate. The current state-of-the-art in diet and physical activity measurement has fallen far behind what the modern technology is able to provide. The field is mature for a substantial innovation. In this application, we propose the development of a new electronic device which has the potential to produce a technological quantum leap in the measurement of diet and physical activity. This button- like device, eButton, will be worn naturally on the chest using a pair of magnets or a pin. A new measurement concept based on the use of the wearable computer will be utilized in our device design. The eButton will contain a low-power, high-performance microprocessor running a simplified version of the LINUX operating system. It will contain numerous innovative designs, including an optical eating detector to monitor eating/drinking/smoking, two miniature cameras that produce a stereo vision to measure food portion size without depending on a reference card, an ear-based oximeter for measurement of heart rate and oxygen saturation, and an extrapolation formula to measure outdoor environment using the US environmental protection agency (EPA) database. eButton will store the multimedia data acquired by a variety of advanced miniature sensors in a flash memory within the device. It will also have a wireless link to a smart phone which will allow researchers to monitor the operating status of eButton remotely in real time. All sensors and function modules will be individually controlled by software to allow researchers to select among the available system resources for their particular needs. Despite the wide functionality of the device, eButton requires an extremely low user respondent burden. The research participant is required to do nothing more than turning on/off the device and recharging its battery at night. During our research, eButton and associated algorithms/software will be designed and constructed in our laboratory by an experienced team of electronic/software engineers based on an early version of the device developed under the NIH GEI diet and physical activity research program. Once eButton is constructed, we will implement a thorough validation process using human subjects to evaluate its accuracy in diet and physical activity assessment by comparing against the doubly-labeled water method as the gold standard.

描述（由申请人提供）：可穿戴的EBUTTON评估能量平衡与环境环境和行为超重和肥胖的流行病，影响了美国60％以上的人口。最近的一项研究表明，肥胖对美国经济的估计直接和间接成本每年至少为2150亿美元。在与肥胖和相关疾病的斗争中，研究和临床社区都需要一种准确的工具来衡量人们在现实生活中的能量摄入和支出。但是，目前，使用最多的工具仍然是一份主观且常常不准确的问卷。当前的饮食和体育锻炼测量最新作品远远落后于现代技术所能提供的。该领域已经成熟，以进行实质性的创新。 在此应用中，我们提出了一种新的电子设备的开发，该设备有可能在饮食和体育活动的测量中产生技术量子飞跃。这种喜欢的纽扣设备Ebutton将使用一对磁铁或销自然地戴在胸部上。我们的设备设计将使用基于可穿戴计算机使用的新测量概念。 Ebutton将包含一个低功率，高性能的微处理器，运行Linux操作系统的简化版本。它将包含许多创新的设计，包括用于监视饮食/吸烟的光学饮食探测器，两个微型相机，它们产生立体声摄像机，可产生立体声的愿景，不依赖参考卡而不依赖参考卡，用于测量心率和氧气饱和度的基于耳朵的血氧仪以及使用US环境环境保护局（EPA）的外推环境（EPA））。 Ebutton将在设备内的闪存中存储由各种高级微型传感器获得的多媒体数据。它还将具有指向智能手机的无线链接，该链接将使研究人员可以实时监视Ebutton的操作状态。所有传感器和功能模块都将由软件单独控制，以允许研究人员在其特定需求的可用系统资源中选择。尽管设备的功能很广，但Ebutton仍需要极低的用户受访者负担。研究参与者只需要打开/关闭设备并在晚上为电池充电而做任何事情。 在我们的研究期间，经验丰富的电子/软件工程师团队将根据NIH GEI饮食和体育活动研究计划开发的设备的早期版本在我们的实验室中设计和构建Ebutton和相关算法/软件。一旦构建了Ebutton，我们将使用人类受试者实施彻底的验证过程，以通过将其与双标记的水方法进行比较，以评估其在饮食和体育锻炼评估中的准确性。
