Abstract(s)
In an unfamiliar environment we spot and explore all available information which might guide us to a desired location. This
largely unconscious processing is done by our trained sensory a
nd cognitive systems. These recognize and memorize sets of
landmarks which allow us to create a mental map of the envi
ronment, and this map enables us to navigate by exploiting
very few but the most important landmarks stored in our
memory. We present a system which integrates a geographic
information system of a building with visu
al landmarks for localizing the user in the building and for tracing and validating
a route for the user's navigation. Hence, the developed
system complements the white cane for improving the user's
autonomy during indoor navigation. Although de
signed for visually impaired persons, the system can be used by any person
for wayfinding in a complex building.
