Abstract(s)
Contrary to outdoor positioning and navigation
systems, there isn’t a counterpart global solution for indoor
environments. Usually, the deployment of an indoor positioning
system must be adapted case by case, according to the
infrastructure and the objective of the localization. A particularly
delicate case is related with persons who are blind or visually
impaired. A robust and easy to use indoor navigation solution
would be extremely useful, but this would also be particularly
difficult to develop, given the special requirements of the system
that would have to be more accurate and user friendly than a
general solution. This paper presents a contribute to this subject,
by proposing a hybrid indoor positioning system adaptable to the
surrounding indoor structure, and dealing with different types of
signals to increase accuracy. This would permit lower the
deployment costs, since it could be done gradually, beginning
with the likely existing Wi-Fi infrastructure to get a fairy
accuracy up to a high accuracy using visual tags and NFC tags
when necessary and possible.
