An Intelligent Physical Activity Monitor

描述（由申请人提供）：对于所有人群的体力活动与健康之间的剂量/反应关系，公认需要具体和可靠的信息。在对体力活动与特定健康相关结果之间的剂量-反应关系进行系统评估和解释之前，需要评估自由生活人群体力活动和能量消耗（EE）的新方法。我们的目标是证明一个低成本，不显眼的加速模式采集和分析系统的可行性。该工具将识别和量化产生这些模式的身体活动。在这个项目的最后，我们将提供一个智能系统，从成本和不引人注目的使用角度来看，它是实用的，从而使它成为大量自由生活人口的流行病学体育活动研究的首选工具。

DESCRIPTION (provided by applicant): There is a recognized need for specific and reliable information regarding the dose/response relationships between physical activity and health for all segments of the population. New methods for assessing physical activity and energy expenditure (EE) in free-living populations are needed before a systematic evaluation and interpretation of these dose-response relationships between physical activity and specific health-related results can be undertaken. Our objective is to demonstrate the feasibility of a low-cost, unobtrusive acceleration pattern acquisition and analysis system. This instrument will identify and quantify the physical activities that generate these patterns. At the end of this program, we will provide an intelligent system that is practical from both a cost and unobtrusive use prospective, thus making it an instrument of choice for epidemiologic physical activity studies of large free-living populations.
