  1. The PuReWidgets toolkit for interactive public display applications Jorge Cardoso

  2. Interactive display

  3. Motivation Interaction in Public Displays •  Every display uses its

    own approach •  Wasted development effort •  Users face inconsistent interaction models We can learn from the desktop platform •  GUIs faced similar problems 3
  4. Requirements The toolkit should support •  Multiple, extensible, PD-specific controls

    •  Various input mechanisms and modalities •  Concurrent interaction •  Asynchronous interaction •  Graphical representations
  5. PD-specific controls Interaction with public displays is different from desktop

    We need specific controls for public displays
  6. Various input mechanisms

  7. Concurrent/shared interaction •  Multiple users •  No single user controlling

    the display
  8. Asynchronous interaction •  Supports interaction even if an application is

    off-screen
  9. PuReWidgets Widget-based toolkit for supporting interactions in public displays • 

    For web-based PD applications •  A widget represents an interactive feature. – Is represented by a class in an object-oriented programming model. – Applications instantiate widgets and receive interaction events via a callback function 9
  10. Features •  Various types of controls –  Action, Options, Text

    entry, Download, Upload, Check-in •  Supports various input mechanisms –  SMS, Bluetooth naming, QR codes, email, touch (with limitations) •  Automatically generates GUIs for desktop and mobile devices •  User identification in input events •  Asynchronous events •  Graphical representations for widgets •  Client and server application models
  11. PuReWidgets Architecture 11

  12. PuReWidgets Implementation •  Google Appengine (server) •  Google Web Toolkit

    – GWT (client) •  Takes advantage of well-known development environment, and user base 12
  13. Initial development •  Continuous refinement cycle – Develop interactive PD applications

    – Gain insight – Refine the toolkit – Refactor the applications 13
  14. Evaluation •  Threefold – Personal experience in developing 3 applications – Programmers’

    evaluation of the toolkit – Audience users’ perception of the interaction/ application model on a real world deployment 14
  15. Conclusion We have now a complete interaction system for public

    display applications •  Web-based –  “Easy” development •  Various widgets –  Supporting diverse interactions •  Multi-user –  Supporting simultaneous, shared interactions •  Multiple input mechanisms –  From web-based, QR codes, to SMS •  Async input –  To support offline interactions and various application models 15
  16. Future work/Ideas Toolkit development Javascript/jQuery library Output widgets for PD

    Remote, Direct manipulation widgets “Native” apps with phonegap Third-party check-ins More flexible application scheduling 16
  17. Future work/Ideas Other ideas Interactive narratives for public displays Application

    coordination between displays Android/iOS “Open-in”/”Share to” Public display near you PD App: users upload content that they can later request the display to show Interactive marketing How to effectively communicate interactivity Guidelines for content creation Wordpress plugin for content creation “Place” representations Who’s around app 17
