摘要

老年人口的增长导致对长期养老设施的需求不断增加。大多数住在这些设施的老人都患有多种慢性疾病。伴随这些疾病的是老年人身心健康的缓慢衰退。需要持续跟踪老年人的日常活动,以便及早发现衰退。为了方便老年人的长期活动跟踪,我们在这项工作中调查了基于wsn的室内定位系统作为已经超负荷的护理人员的支持的潜力。通过在大学医院老年护理中心部署基于wsn的实时室内定位系统(WSN-RTLS) 8个月,我们发现:(1)每位老年人的日常活动呈现重复模式。然而,这种模式因人而异。(2)老年人的流动性水平具有显著的变异性,即并非所有老年人的流动性水平都呈现重复模式。这表明,仅仅是老年人在设施中走动的数量并不是行为模型的合适目标。长老们出现的确切地点更有意义。原位WSN-RTLSs将有助于早期发现老年人的身体或智力衰退。

Towards long-term mobility tracking in NTU hospital's elder care center
Growth of the elder population gives rise to the increasing demand of long-term elder-care facilities. Most elders living in such facilities suffer from multiple chronic illnesses. Accompanying these illnesses are slow declines of the elders' physical and mental health. Continuous tracking of the elders' daily activities is required to detect the declines early. To facilitate long-term mobility tracking of the elders, we investigate, in this work, the potential of a WSN-based indoor location system as a support for the already-overloaded nursing staff. Through the deployment of a WSN-based Real-Time Indoor Location System (WSN-RTLS) in the university hospital's elder care center for 8 months, we find that: (1) each elder's daily mobility shows a reoccurring pattern. The pattern, however, differs from individual to individual. (2) The mobility level shows a significant variability, i.e., not all elders show reoccurring patterns in mobility levels. These suggest that mere quantity of how much the elders move around the facility will not be a suitable target for behavioral modeling. Exact location of the elders' presence, rather, is more relevant. Insitu WSN-RTLSs would be an enabler towards early detection of the elders' physical or mental decline.
