5. Cooperative Work Framework understanding direct communication participants control and feedback artifacts of work PP A

6. Cooperative Work Framework  Computer mediated communication  Meeting and decision support systems  Shared applications and artifacts

7. Computer-mediated Communication  Email and bulletin boards  Structured message systems  Video conferences & communication  Virtual collaborative environments

8. Meeting and Decision Support Systems  Argumentation Tools  Meeting Rooms  Shared Drawing Surfaces

9. Argumentation Tools  Often hypertext-like structure  Concurrency control

10. Meeting Rooms  Specially constructed rooms  WYSIWIS  Floor control policies  Social and software protocols  Support for deictic references  The cool rooms are expensive!

11. Shared Work Surfaces  Take meeting rooms, make them run between multiple locations!  Notification Collage, kinda…

12. Shared Applications & Artifacts  Sharing work domain  Shared PCs & Shared Window Systems Shared PCs & Shared Window Systems  Shared Editors  Co-authoring systems  Shared Diaries  Communication through the artifact

13. A Redefined Matrix concurrent synchronized mixed serial unsynchronized co-locatedremote meeting rooms video conferences, video wall, etc. shared work surfaces and editors, shared PCs and windows co-authoring systems, shared calendars argumentation tools email and structured messages, electronic conferences

14. design: Granularity large small frequentinfrequent chunk size update network file systems with locking co-authoring systems meeting system with floor holder shared editors

15. design: Sharing  Shared databases  WYSIWIS  Race conditions

16. Integrating Communication & Work understanding direct communication participants control and feedback artifacts of work PP A deixis feedthrough

17. Design Time!  Feedback and network delays  Architecture: centralized & replicated  Architecture: shared window  General problems, blah blah blah…

18. Design Perspectives  Distributed Systems  Communications  Human Computer Interaction  Artificial Intelligence  Social Theory

19. The End *whew!*
