Development of health monitoring system at home

在维护人们的总体健康，特别是老年人的健康方面，通过他们在自己家中的日常活动，远程监测他们日常生活中的健康状况可能是有用的。本研究旨在发展家庭健康监测系统。使用我们的系统，监测过程是完全自动化的，不需要在受试者身上放置任何传感器，也不需要受试者进行任何操作。在本研究中，通过将传感器安装在受试者自己家中的家具和配件上，监测其日常活动和生理参数。我们安装了几套监控系统，分别是单人居住主体的住宅和一家三代人的住宅。监测可以自动实现，无需在受试者上放置任何传感器（例如，电极和袖带传感器），在大约三个多月的时间内无需任何人工操作。我们开发了一些完全自动化的行为数据评估方法。并用实测数据对这些方法进行了评价。对于评价，这些方法在实际情况中也应该是有用的。研制并评价了新型厕所体重监测仪。重量监测仪比普通监测仪体积小，安装方便。此外，我们还研究了主体的隐私问题和监控系统的安全性。总之，在家中进行长期健康监测是可能的。并具有全自动的数据评估过程，支持监控。

In maintaining the general health of people, and especially the health of the elderly, it can be useful to remotely monitor their health status in their daily lives, through their daily routines at their own home. This study is for developing health-monitoring systems at home. With our system, the monitoring procedure was fully automated and did not require the placement of any sensors on the subjects or require any operations by the subjects. In this study, the monitoring of the daily activities and physiological parameters by using sensors attached to house furnishings and fittings located in the subjects' own house. We installed several monitoring system for houses of single living subject and a house of a family with three generation. Monitoring can be achieved automatically, without placing any sensors on the subject (e.g., electrodes and cuff sensors) during about over thee months without any human operation. We developed some fully automated evaluation methods of behavioral data. And those methods were evaluated with practical obtained data. With evaluations, those methods were supposed to be useful also in practical situations. The new body weight monitor in toilet was developed and evaluated. The weight monitor was smaller-sized than usual monitor, and easily to be installed. Also we have examined about the privacy problem of subjects and security of monitoring systems. In conclusion, the long-term health monitoring at home is possible. And the monitoring can be supported with fully automatic data evaluation process.
