  abstract = "In this paper, we propose the use of specific system
              architecture, based on mobile device, for navigation
              in urban environments. The aim of this work is to
              assess how virtual and augmented reality interface
              paradigms can provide enhanced location based
              services using real-time techniques in the context of
              these two different technologies. The virtual reality
              interface is based on faithful graphical representation
              of the localities of interest, coupled with sensory
              information on the location and orientation of the
              user, while the augmented reality interface uses computer
              vision techniques to capture patterns from the
              real environment and overlay additional way-finding
              information, aligned with real imagery, in real-time.
              The knowledge obtained from the evaluation of
              the virtual reality navigational experience has been
              used to inform the design of the augmented reality
              interface. Initial results of the user testing of the
              experimental augmented reality system for navigation
              are presented."
