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 and cognitive systems. These recognize and memorize sets of landmarks which allow us to create a mental map of the environment, 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 visual 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 designed for visually impaired persons, the system can be used by any person for wayfinding in a complex building
