  18. Reference System architecture Doc text img video Web Site Web Browser MAXML Browser plug-in Annotation Server Annotated Doc Require login text img video Login response Authentication Response Request Authentication Login OpenID Provider (O.P)

  19. Browser Plug-in Browser plug-in • Used programming language • Javascript, actionscript • XML Processor • Submit and query annotations Browser toolbar XML Processor Annotator Renderer

  20. Browser Plug-in • Browser toolbar • User interface of plug-in • Annotator • Add text annotation, image annotation and reference link directly • Flash video annotator • Add video annotation • Renderer • Render annotations which queried by XML processor

  21. Annotation Server Annotation Server • Web Server • Apache with PHP extension • Annotation DB • MySQL server Web Server Annotation DB OpenID Authenticator XML Processor Annotation

  22. Annotation Server • XML Processor • Processes add and query annotations request from browser plug-in. • OpenID Authenticator • Open source library with little fix. • Process OpenID login request from browser plug-in.

  23. Evaluation

  24. E-learning thru Web Annotation • Peer Assessments by annotation • Cooperative Learning by annotation • Information Problem Solving • behavior tracing • Information collection – search • Information processing – reading, annotation, sharing, … • …..

  25. Q&A • Multimedia annotation toolbar is available at • http://dcsw3.cis.nctu.edu.tw/DCSLab/ Thank you!
