In-Depth Information
The service can send the following alerts:
If an elderly person has been on the bed too long time (a case in which the care-giver
assumes that the elderly might be experiencing difficulty or health issues).
If an elderly person has left the bed too long time during a certain period of time (such
as night time) and which might mean that elderly person has fallen down.
The following three parameters can be adjusted:
Time duration after which an alarm is issued, if an elderly is still in bed (specified in
minutes)
Time duration, during “night time” (see next parameter) after which a care-giver
should be alerted if the elderly is out of bed.
The start and end times of the 'night time' period. These two times tell the service what
time is considered to be “night time”, i.e. the period during which the care-giver wants
to receive alerts if the elderly leaves the bed for a certain time (see previous parameter).
Example of these parameters is when the system raises an alarm if the patient is in bed for
longer than 10 hours, and also in case the patient left the bed between 10pm and 6am for
longer than one hour (specified as 60 minutes). Since very often the elderly person takes a
nap in the afternoon, it was suggested by the regional partners that additional time period
of afternoon sleep is defined, similar to the night-time sleep period. However, this could not
be implemented in the time frame of the project.
3.1.5 Intelligent front door service
This service monitors the status of the elderly's front door and monitors the presence of the
elderly in the home with the help of motion detection (and bed sensor information if such a
sensor is installed). On the main service page a care-giver can see the status of the front
door, as well as the last times it was opened or closed and the last time a movement was
recorded in the home.
Line for current status also shows whether the system has assumed that the elderly is
present in the home or not at this moment. The system makes this conclusion by monitoring
the various sensors, such as cooking sensor, door activity sensor, fridge door activity sensor,
motion detection activity sensor. Each time when an activity is detected by one of these
sensors it assumes that the elderly is active and in the home. The service also monitors the
bed status (if bed sensor is installed), so that if there is no activity but the elderly is sleeping
then this too will indicate an elderly's presence in the home. If there is no activity on any of
these sensors for a certain amount of time (customisable from the service screen in the web
portal) then the system will report to care-givers that the elderly is absent from the home
and will make notification accordingly. Alerts are sent if the front door has been opened for
more than a certain amount of minutes, when an elderly is absent from the house for certain
hours and if an elderly is assumed to be absent from home for too long time.
The front door alarm is a service that can be customised depending on the elderly life
pattern. For this purpose, four parameters can be adjusted according to:
Time duration after which the front door will issue an alert if it stays opened, specified
in minutes.
