    LUCID demonstrator: Co-loco LUCID demonstrator: Co-loco Presentation Transcript

    • A knowledge-sharing event investigating current opportunities and the future of context-aware information delivery on mobile devices. CO-LOCO a geo-socialising application
    • Aims
      • explore geo-socialising applications
      • explore co-located people and place discovery:
      • enable users to tag locations – create POIs
      • enable users to interact with each other – via messaging and via comments on POIs
      • game aspect – interaction means points
    • Approach
      • client-server interaction
      • - XML (client-agnostic)
      • client side
      • - JME (well supported)
      • - KXML mobile XML parser ~ small footprint
      • - MobiMaps ~ openstreetmaps flavour
      • - GPS location
    • Demonstrator: overview
    • Demonstrator: overview
    • Demonstrator Overview
      • users sign up / log in
      • map view of area – including UGC POIs and known users (“friends”)
      • list view too
      • Users can:
      • contribute POIs (text; images)
      • comment
      • messaging – direct to friend or to all
      • gain/see points
    • Issues
      • usability of mapping apps on small screens
      • high data overhead (map tiles) – FIZ pinholes
      • user acceptance issues - privacy
        • - only friends can see each other’s location
        • - strangers only know that X is in the area
        • - only friends can directly message each other
        • - blacklisting if necessary
    • Conclusions
      • tech barriers: JME implementations – not all JSRs (i.e. java libraries for location, multimedia etc.); can be difficult to find out what JSRs are implemented.
      • generic JME UI toolkit inferior to e.g. LWUIT (L ightweight UI Toolkit )
      • usability and privacy are key
      • consider caching (lower data transfer)
    • Next steps
      • Improve UI
      • larger scale user testing (over FIZ)
      • explore pervasive game applications
      • alternate mapping – map source; map contents
      • (web) front-end = geoblog?
      • caching / strategies for popularity!
