Evaluation of an Augmented Photograph-Based Pedestrian Navigation System

Map interfaces are the quasi-standard for car navigation systems, and are usually the first choice for mobile pedestrian navigation systems. Alternatives are being investigated in research and industry that possibly suit the settings and needs of the person on foot better. One solution is augmented reality (AR), which blends navigation instructions with the view of the real world. However, research usually focuses too much on the technical implementation, leaving little time for a thorough assessment of the actual benefits of such a system. In this paper we present an evaluation of a mobile pedestrian navigation system prototype. The system provides a simplified augmented reality experience by presenting visually augmented photographs instead of a real-time video stream. We compare the usability of the AR interface with that of a map-based interface in a field evaluation. Our results challenge the map approach and suggest that AR is not only a serious alternative, but also potentially more suited for route presentation in PNS.
