E�cient human-computer-interaction is a key to success for
navigation systems, in particular when pedestrians are using
them. Due to the increasing computational power of recent
mobile devices, complex multimedia user interfaces to pedestrian
navigation systems can be implemented. In order to
be able to provide the best-suited interface to each user, we
present a user study comparing not only three map presentation
modes (bird's eye, egocentric and a combined one),
but also involving the users' sense of direction as a second
independent factor. In the experiment conducted, we did
not focus on a global navigation task, but on the repeated
subtask of locating objects on the map. ANOVA analysis
of the task completion time revealed a signi�cant interaction
e�ect of presentation mode and the sense of direction of
the test persons. Consequently, we advocate user-adaptive
presentation modes for pedestrian navigation systems.
