7、能量大小。 第四，它会以原始的曲线、图表、表格、条形图和数据等方式来显示对身体动作的深入分析，比如 限定步伐的因素，速度，活动所消耗的能量，心电图或心率（使用者可自主选择）等等。 第五，它可以计算任何时间任何地点的身体锻炼和活动的范围、距离、力量、功效和能量消耗。IDE EA 有以下几个主要作用：在 24 小时基础上记录和回放身体动作和姿势，可以存储成百上千万的数据 点以便于日后分析。详细请看“身体活动测量”的例子。 Actview：用于身体活动和体谅消耗的估算 Actview 是 IDEEA 系统中不可缺少的一部分，它使得 IDEEA 里的数据汇总到一起进行分析。使用 Act view 可以
8、使得 IDEEA 里的数据结合起来做以下的操作：将一个人一天的活动进行回放。你可以选择 回放的起点，也可以调整回放的速度。增至更多特定的活动，活动的力量，能量消耗，活动速度， 活动类型和其他变量。在图表里细致地显示各种活动花费时间的百分比。详细地检查每个活动的开 始和结束，以及速度、力量、能量消耗和距离。做出反应能量消耗的条形图以及力量和其他信息。 通过看编辑的表格输出原始数据。Actview 是一种以窗口为基础的程序，其功能非常强大，它可以分 析和设想身体锻炼和活动的类型、持续时间、频率和强度以及人们所消耗的能量的估算。能量消耗 ，力量，速度和原始数据的曲线是不断变化的。你可以以点、面的方式
9、选择活动的任一部分或者根 据兴趣选取运动的一段。你也可以选择每段每单元的速度（例如，每小时几千米或多少焦耳），就 像使用录像带一样。左撇子的人也有适合的运动，他们可以以高准确率来使现实生活的动作和姿势 变得很有活力。 IDEEA 和 Actview 结合起来不但可以提供运动轨迹变化的信息，而且还告诉我们跟身体活动有关的生 活质量是提高、降低还是保持不变。它还可以在提高身体活动水平的发展战略方面为你提供信息和 指导。 它可以识别包括躺、坐、走、爬楼梯、跑、跳等 40 多种活动类型。详见“身体活动类型”。为身体 活动的开始、持续时间和频率以及一天内的重要事件提供精确的记录，根据从几秒到几天的不同时
10、 间段将身体活动和能量消耗进行分析和分类。评定身体活动和行为类型。 这个 Actview 里的截屏概括了在给出的期间内身体活动和每个姿势的百分比。身体活动类型的持续 时间、数据（由步骤构成）、运动速度都呈现在表格的右边栏。当你改变观察时间时，对身体活动 、姿势、行为路线的测量都由表格左上角的列表选择来进行及时的更新和变化或者也可以通过移动 颜色滚动条左右两端的绿色端点来实现。 对于身体活动来说，IDEEA 还可以进行姿势的检测。 它通过人工智能和网络神经系统的先进技术计算身体活动（走路和跑步的速度）的数量和强度来提 供便携式仪器曾被报道过的最精确的结果。以速度分析为例。 对一个在自由条件下生活

19、uman life. In a way, it is life. Like a lightning strike in human existence, automation and industrialization in a short 50-year period have dramatically reduced the amount of daily physical activity, and completely changed our lifestyle and work environment. Changes in physical activity can lead to
20、 body imbalance (e.g., energy imbalance) and diseases such as obesity, cardiovascular dysfunction, and diabetes. The U.S. government health website has listed physical activity as the leading health indicator for the Nation in the coming 10 years. Quantifying physical activity and its energy cost is
21、 the first step toward the solution of these problems. After 12 years of research work and several hundred-thousand lines of coding, Dr. Ming Sun and his team introduced the Intelligent Device for Energy Expenditure and Activity(IDEEA), a device that for the first time can analyze body motion, measu

40、r obesity, rehabilitation, osteoporosis, and many other studies. All other commercial devices tell you the vibration sensed by the sensor(s) attached to the part of body. Thus a childs waving hand can generate more signals than an adult climbing stairs, which is not correct in terms of energy expend

IDEEA uses advanced algorithms such as artificial intelligence and neural network that integrates signals from multiple sensors of different body parts to derive intelligently the exact type of activity the person is performing (sitting, standing, jumping, stair climbing/des
42、cending.) with the highest possible accuracy (a study by Dr. Pi-Sunyers group from Columbia University showed average accuracy 98.5% for 76 subjects studied). The results such as power, mechanical work, and energy expenditure estimates were calibrated by the most accurate whole-room calorimeters and
43、 the largest precision force platform, and validated on hundreds of tests in multiple clinical studies, thus has much higher accuracy and accountability. IDEEA measures and records millions of data points so that every slight movement or activity is recorded and saved for later use. While other devi
44、ces only record an average of vibrations for a given period (say, on 1-minute intervals). IDEEA is designed from ground-up by researchers conducting clinical studies. It presents the information a researcher needs, such as the type of physical activity, its onset, duration, frequency, intensity (e.g
45、., speed of walking or running), mechanical power generated, and related energy cost. Others output a number or a few numbers in a given time period that basically tells the level of sensor vibration. Perhaps the most important difference is that the software that comes with IDEEA enables you to pla
46、y back the animation of what actually happened for the subject (e.g., At exactly what time a subject fell on the ground? What was the last supporting leg before falling? And many more) at any given time. The playback speed can be changed from 1:1 to 1:60 to speed up viewing. Graphs, charts, tables,
47、and statistics are designed for scientific view and can be shown for any selected time period dynamically, printed out, or saved to a database of your own. Sample Use of IDEEA in Research Quantify the type, duration, frequency, and intensity of various physical activities in free living for a divers
48、ified population IDEEA can help to evaluate: the common types of activities, speed of locomotion, and EE during work in an office, factory, or in the field, class time in school, leisure time at home, military training or expedition, or most indoor/outdoor activities. You can also assess the onset,
49、duration, frequency, intensity, and amount of PA/exercise during these activities; the contribution of each category of PA/exercise to the total amount of PA/exercise; and types and duration of sedentary activities and resting periods among free-living adults. Estimate long-term variations in physical activities (such as labor, work, and leisure), and energy requirement during these activities and their relations with body composition and weight regulation. IDEEA system can answer these questions: What is the amount of energy expenditure caused by physical activity/exer
