  1. ICS 463, Intro to Human Computer Interaction Design: 12. Computer Supported Collaborative Work Dan Suthers

  2. Forms of CSCW Synchronous Asynchronous Co-located Distributed

  3. Colab (late 1980’s onwards) • Synchronous-local • Liveboard, individual workstations • Software • Cognoter • Argnoter • Boardnoter • Can work in private or public spaces

  4. Colab: Hardware innovations • Liveboards • Light-based • Ultrasonic

  5. Colab: Cognoter • Preparing an outline of a presentation • Based on three-phase model: • Brainstorm (also uses Boardnoter) • Organize • Evaluate • Others have developed similar schemes • Let’s see a video …

  6. Colab: Argnoter • Presentation and evaluation of proposals • Also three-phase model • Propose - placed in the workspace • Argue - annotated by participants • Evaluate - rank evaluation criteria and apply under different belief sets • Example of a Group Decision Support System (GDSS)

  7. Colab: Portable meetings & ideas • Vison: Colab workspaces available everywhere, interconnected

  8. Synchronous-Remote CSCW • Typically two components: • Shared workspaces • Natural language interaction • Video • Audio • Textual “chat” • Commercial tools: NetMeeting, Polycom videoconferencing etc.

  9. Activity / presence awareness • Is Jan in his office? • What is he doing? • Is he willing to talk?

  10. Eye Contact Video Tunnel Hydra

  11. Access Grid (HITS on steroids?)

  12. I think … • The technology is great, but the real issues are in designing the workspaces (representations, collaborative work tools) and activity structures

  13. Asynchronous Examples • Discussion tools, e.g. Email, Threaded discussions • Document repositories • BSCW http://bscw.gmd.de/ • Document annotation systems • Kukakuka, Pink • JIME http://www-jime.open.ac.uk/ • Multimedia/Mixed • Knowledge Forum http://kf.oise.utoronto.ca/kfdemo/kfdemo.html • Teamwave

  14. Synchronous Issues • Awareness • Who is on right now? • Is Jan answering my question, or did he leave for lunch? • Coherence • Who is answering whom? • Value of video • When are talking heads valuable? • Demonstrations, negotiation, familiarity

  15. Asynchronous Issues • Context and coherence • Artifact-centered discourse • What is this message about? • Where are the messages about this artifact? • Picking up where we left off • What was the last idea proposed? • What is she responding to?

  16. Asynchronous Issues Cont. • Single versus multiple workspaces • Multiple threads in a single workspace • Movement of ideas between multiple workspaces and groups • Group Awareness • Are there any new messages? • Has anyone been reading my proposal?

  17. General Issues • Identity and trust • Cross cultural communications • Serendipity of informal interactions • Always-on shared spaces? • Virtual coffee pot?

  18. More Design Issues and Ideas • Viability compared to alternatives • Build based on existing work practice • May invent new collaborative practices • Local conventions develop: acclimate newcomers • Time zones a problem • Synchronous meetings with large groups require facilitation • Delays can impede rhythm of communication
