Research on monitoring of physical and mental reserve capacities at home

该项目试图建立一种监测家庭体力和精神储备能力的方法。为此，研制了一种多传感器记录仪。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。在一所房子里放置了两套多传感器记录仪，以便监测不同地点日常活动的差异。在评估研究中，使用自行车测力计和可穿戴身体加速度传感器(Actigraph)来估计最大体力活动水平，并要求受试者记录监测过程中发生的精神压力。在初步研究中，证实了多传感器记录仪系统工作良好，在获得的趋势数据上清晰地反映了日常活动的特征，观察到的日常活动模式与人体加速度数据具有很好的相关性。遗憾的是，由于一名调查员辞职，项目的进展大大落后于最初计划的时间表，因此，即使在分配的期间结束时，也无法获得估计储备能力的预期结果。目前，孤寡老人之家的评估研究仍在继续，可以预计研究很快就会完成。虽然目前所取得的成果相当差，因此我们不能确定监测方法的有效性，但这个项目的基本概念仍然是合理的，我们相信经过三年的尝试并不是微不足道的。

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.
