  1. Agile Design Exploration:User Interface Concepts for Future Navigation Systems Volker Paelke, Karsten Nebe Leibniz University Hannover, University of Paderborn Germany

  2. 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

  3. Approach: Exploration of the Design Space Available Design Space Expandedbynew Technologies User Requirements Changingusergroups Explorepromising conceptswithusers Establish a framework fordynamicmaps Agile development method

  4. Exploratory Design Agile Scrum Process

  5. Exploratory Design Extended Scrum Process

  6. Prototypes: “Dynamic Maps” for Car Navigation • Adaptive On-/Offroad-Navigation • Specific requirements beyond current PNDs

  7. Prototypes: “Dynamic Maps” for Car Navigation • On-/Offroad-Navigation • Adaptation of display configuration

  8. Prototypes: “Dynamic Maps” for Car Navigation • On-/Offroad-Navigation • Adaptation of display configuration

  9. Prototypes: “Dynamic Maps” for Car Navigation • On-/Offroad-Navigation • Multiple input modalities (touch, rotary selector, speech)

  10. Prototypes: “Dynamic Maps” for Car Navigation • On-/Offroad-Navigation • Iterative Prototyping in an Agile UCD Process involvinghardware, software and UI design

  11. Prototypes: “Dynamic Maps” for Car Navigation • On-/Offroad-Navigation • User tests integrated into design iterations • Display adaptation well accepted • Input adaptation irritating if not notified • Preference for parallel input modalities

  12. Prototypes: “Dynamic Maps” for Pedestrian Navigation

  13. Prototypes: “Dynamic Maps” for Pedestrian Navigation Indoor Outdoor • Indoor: • Preference for simple abstracted 3D visualizations with 2D guidance • Outdoor: • Preference for maps augmented with landmarks • Visualization style dependent on landmark type

  14. 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

  15. Thank you for your attention!
