Motivation
Navigation becomes a commodity PDAs, PNDs, Smartphones Extensions: 3D display, landmarks, POIs, “intelligent routing” More than Eye Candy ? At the same time: limited to conventional metaphors

On-/Offroad-Navigation User tests integrated into design iterations
• Display adaptation well accepted
• Input adaptation irritating if not notified
• Preference for parallel input modalities

Indoor: Preference for simple abstracted 3D visualizations with 2D guidance
Outdoor: Preference for maps augmented with landmarks Visualization style dependent on landmark type
Conclusions
A large opportunity exists to improve the usability of future navigation systems through “dynamic map” concepts
improving input improving output better functionality adapting to users, environment and task
A user-centred process is required to develop innovations that are of actual benefit to the user
An agile design process seems to be well suited Selected system probes were developed and tested to
validate key assumptions and to inform future design decisions
