Resource-Adaptive Navigation Systems

Antonio Krüger, University of Saarland, Germany

Pedestrian navigation systems have to take into account not only the cognitive resources of the user, but also the differing technical constraints of the devices that are used to access navigational way descriptions. The presented work describes the REAL-System that is a hybrid navigation system, consisting of two parts: the indoor-navigation system IRREAL and the outdoor version ARREAL. Both systems try to adept their (especially graphical) presentations to the user's speed, spatial familiarity and goals. Whereas IRREAL works with an infrastructure of custom-made infrared senders, the ARREAL system relies on GPS and an electronic compass to determine its position. Experiences and Results of both approaches are discussed.
