Research on monitoring of physical and mental reserve capacities at home

该项目试图建立一种监测家庭身心储备能力的方法。为此，开发了一种称为多传感器测井仪的监测仪器。它有两个运动传感器，两个加速度传感器，一个音频麦克风，一个湿度传感器，一个温度传感器和一个照度传感器。两套多传感器记录器被放置在一个房子里，这样就可以监测不同地方的日常活动的差异。在评估研究中，我们使用自行车测力计和可穿戴的身体加速度传感器（活动记录仪）来估计身体活动的最大水平，并要求受试者记录监测期间发生的精神压力。在初步研究中，证实了多传感器记录器系统完美地工作，使得日常活动的特征清楚地反映在所获得的趋势数据上，并且观察到的日常活动模式与身体加速度数据具有良好的相关性。不幸的是，由于一名调查员辞职，项目进展大大落后于最初计划的时间表，因此，即使在指定期间结束时，也无法获得估计储备能力的预期结果。目前，隔离老人之家的评估研究仍在继续，预计研究将很快完成。虽然目前取得的结果相当差，因此我们无法确认监测方法的有效性，但该项目的基本概念仍然是合理的，我们相信通过三年进行的尝试并非微不足道。

This project was an attempt to establish a method of monitoring physical and mental reserve capacities at home. A monitoring instrument, called multi-sensor logger, was developed for this purpose. It has two motion sensors, two acceleration sensors, an audio microphone, a humidity sensor, a temperature sensor, and an illuminance sensor. Two sets of multi-sensor logger were placed in a house so that difference in daily activities at different places could be monitored. For evaluation studies, a bicycle ergometer and a wearable body acceleration sensor (actigraph) were used to estimate the maximum level of physical activity, and we asked the subjects to record mental stresses occurred during monitoring. In the preliminary study, it was confirmed that the multi-sensor logger system works perfectly so that the feature of daily activity was clearly reflected on the obtained trend data, and the observed pattern of daily activity correlated well to the body acceleration data. Unfortunately, due to the resignation of an investigator, the progress of the project had delayed largely behind the initially planned schedule, and consequently, expected results to estimate reserve capacities could not be obtained yet even at the end of the assigned period. At present, the evaluation study in the home of isolate-living elderly is still continued, and it can be expected that the study will be completed soon. Although the obtained result is quite poor at present and thus we could not confirm the effectiveness of the monitoring method, the basic concept of this project is still reasonable and we believe that the attempt performed through three years was not insignificant.
