The problem of dementia is becoming more and more prominent as
global ageing populations are growing fast. In nursing homes, elderly
people with dementia are often restrained in bed or administered
sleeping pills. The purpose of such treatment is to prevent patients
from wandering, which may result in getting lost or accidents. This
monitoring system, equipped with event sequence tracking and
different kinds of sensing technologies, including remote vital sign
sensor and non-invasive imaging device, can continually monitor the
patient’s sleep and night-time activities. In case of unusual incident,
the system will send an alert message to the caregiver at once,
reducing the workload and increasing the efficiency of the caregiver.
