Abstract :
Human navigation is based on space mental representations built from several sensory data. This paper investigates the interaction between the visual and tactile modalities during navigation within the experimental platform "perception-movement". A new space representation for navigation and its visual-to-tactile coding are proposed. Four experiments have validated this new coding through some basic navigation tasks. Results obtained show that it is possible to integrate the proposed space representation into a portable navigation tool which could be useful for navigation assistance of the blind/visual impaired
