While car navigation systems are widely commercialized already today, pedestrian information systems are still in the early research stage. However, recent progress in mobile computing has opened perspectives for pedestrian navigation systems. In this context, graphics is and will still be an important modality to convey all types of route information. This paper will address the question how to generate graphics for navigation systems that help pedestrians, e.g., airport passengers, city tourists or conference attendees, to find their way in complex environments. We will discuss how the presentation of graphics can be tailored to various technical and cognitive constraints, and we will demonstrate our ideas within a scenario where a passenger of an airport gets navigational help from a stationary info booth and afterwards on her way via a handheld device (PDA). Both the 3D visualization at the info booth and the sketch-like presentation on the PDA are generated from the same data and by the same system, yet are adapted to the specific situation, output medium and user as far as possible.
