Abstract

In this paper, we present a vocal ontology of"br" OpenStreetMap data for the apprehension of space by visually"br" impaired people. Indeed, the platform based on produsage gives a"br" freedom to data producers to choose the descriptors of geocoded"br" locations. Unfortunately, this freedom, called also folksonomy leads"br" to complicate subsequent searches of data. We try to solve this issue"br" in a simple but usable method to extract data from OSM databases in"br" order to send them to visually impaired people using Text To Speech"br" technology. We focus on how to help people suffering from visual"br" disability to plan their itinerary, to comprehend a map by querying"br" computer and getting information about surrounding environment in"br" a mono-modal human-computer dialogue.
