Agile Design Exploration: User Interface Concepts for Future Navigation Systems

This paper explores innovative user interface concepts for future navigation systems, highlighting the evolution of navigation technologies such as PDAs, smartphones, and 3D displays. It emphasizes the need for user-centered design by investigating dynamic mapping solutions for both car and pedestrian navigation. Employing an agile development approach, it showcases prototypes that adapt to user preferences and environmental contexts, aiming to enhance usability and functionality. The findings underscore the importance of iterative testing and adapting input modalities to deliver better user experiences in navigation.

  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!
