spreading of diseases amongst Alzheimer’s patients.
In addition, privacy is an area of prime importance,
as assistive technologies should not be needlessly
intrusive or the elderly community will simply
refuse to use them, despite their potential benefits.
Hence the work in this paper did not make use of
any visual surveillance equipment. Nevertheless
even RFID sensors can be intrusive to a certain
extent and once such approach that will be
investigated is the integration of privacy policies
into our current hierarchal approach. A person may
want to switch some or all of the sensors off from
time to time, or may opt for a programmed approach
where more sensors can be used at certain times of
the day, or if the system believes that the person is in
need of help. The question of accuracy is a difficult
one as increased detection usually means false
positives and a trade off between the two is
necessary. However policies for when more
information is needed could be used to mitigate this
problem.
