Monitoring and analysis of sleep pattern for people with early dementia

Knowledge discovery from activity monitoring to support independent living of people with early dementia

“…Dataset used in this study were collected by monitoring clients with early dementia who live independently in home environments embedded using NOCTURNAL (Night Optimised Care Technology for UseRs Needing Assisted Lifestyles) system [7]. As illustrated in Fig.…”

“…All analysis is carried out using an in-house personalized activity pattern visualization system, PA ViS [7]. The PA ViS system is a Java-based application that provides an interactive toolkit for caregivers to view the activity profiles and for investigators to analyze activity patterns based on sensory data gathered at users' home via the telecare service.…”

Design and Modelling of the Nocturnal AAL Care System

“…It is also of interest because of the negative impact that lack of sleep and consequent anxiety causes for the informal carer in the home of the person with dementia. The support provided is also relatively unusual in that the AAL services are focused on identifying negative behaviours at nighttime such as restlessness and wakefulness [6] and then responding to these behaviours with interventions that are designed to have a therapeutic impact. The focus on nighttime AAL services centres around lighting and guidance, motion monitoring and intervention decision-support.…”

Contact-free measurement of respiratory rate using infrared and vibration sensors

“…The studies in [8][9][10][11][12][13][14] exemplify the second group. In [8,9], radar sensor based systems for central apnea detection and respiratory monitoring are described, respectively.…”

“…A biosignal measurement system, which measures the air pressure in an air mattress, to monitor the heartbeat and respiration of a person lying in bed is introduced in [10]. Wang et al [11] propose a sensor based sleep monitoring system to assess the quantity and quality of sleep for elderly people. But it uses PIR sensors in on/off mode only and does not determine the period of breathing.…”
