The second type of sensors is
responsible for the detection of forgotten switched on electrical
appliances by measuring the voltage and current consumption of
each one appliance. Consequently, these two sensor categories
may guarantee the safe living of the elderly inside their home
environments without needing exclusive intensive care. Finally,
the core elements of the proposed architecture are an embedded
processor and a general purpose PC which are employed in order
to co-ordinate and to manage the AAL environment. A possible
scenario which highlights their applicability is the execution of
the cognitive training software and then the tasks of storing and
processing the physical training performance information.
