Case studies
In this section two separate case studies are reported. In
both case studies, the data collection system consists of an
array of wireless motion sensors (kitchen, bedroom, bathroom,
lounge) and door entry point sensors (front door and
back door) were used. For both case studies, JustChecking
(JustChecking 2010) equipment is used. More details about
the technical characteristics of the hardware equipment is
available from (JustChecking 2010). However, we should
emphasise that the results and discussion presented below
is not restricted to the usage of this equipment only. In both
cases only one resident who suffered from dementia living
in their own home is monitored. The caregiver has access
to the daily activities of the patient and they are monitored
from a secure web interface. The output of all sensors are
discrete values. These discrete values represent presence or
absence from a specific area. When the patient moves from
one room to another, the status of the sensor will vary.
