  1. Groupware Groupware C.A. Ellis, S.J. Gibbs, G.L. Rein Chapter 13 Michael Rounding

  2. CSCW Defined “…[CSCW] is about groups of users – how to design systems to support their work as a group and how to understand the effect of technology on their work patterns…” Michael Rounding

  3. Time/Space Matrix Same place Different place Same time Face-to-face conversation Telephone Different time Post-it note Letter

  4. Time/Space Matrix Co-located Remote Face-to-face conversation Synchronous Telephone Asynchronous Post-it note Letter

  5. Cooperative Work Framework understanding directcommunication P P participants control and feedback A artifacts of work

  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 Editors • Co-authoring systems • Shared Diaries • Communication through the artifact

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

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

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

  16. Integrating Communication & Work understanding directcommunication P P participants deixis feedthrough control and feedback A artifacts of work

  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!*
