1. Social Translucence: Designing Systems that Support Social Processes Thomas Erickson and Wendy A. Kellogg ACM Transactions on Computer Human Interaction, Vol.7, No. 1, March 2000

2. Foundations: Social Translucence (versus Transparency_ What is a “Socially Translucent System”? Example: Door opens from stairwell into the hall vs. Three properties: Visibility Social info visible Awareness Visibility supports awareness Accountability Awareness enables accountability

3. Translucence & Power of Constraints P62-65

4. Application Domain: Knowledge Management Knowledge Management –Provide organizations with tools for capturing, retrieving, and disseminating info –Schemes for organizing and retrieving info Knowledge Community –Place within which people would discover, use, and manipulate knowledge, and could encounter and interact with others who are doing likewise Conversation –Superb method for eliciting, unpacking, articulating, applying, and recontextualizing knowledge

5. Vision: Conversationally based Knowledge Communities Activity Support –Support long-running deep, coherent conversations that can be steered by their participants Conversation Visualization an Restructuring –Conversation reusable –Search, navigate, and visualize conversations –Summarize, highlight, link, annotate conversations Organization Knowledge Spaces –Semiautonomous knowledge communities –Each community exercising control ways and means through which its knowledge is shared with larger organizations

6. Making Activity Visible The Realist Approach The Mimetic Approach Abstract Approach

7. Realist Approach Teleconferencing and Videospace Systems Pros: Minimizes the difficulty of producing and interpreting social cues Cons: a. Resolution limited b. Very expensive c. Scaling

8. Mimetic Approach Graphical MUDS and Virtual Reality Systems –Avatars Pros: Reduces bandwidth requirement Cons: a. Scaling issues b. Social cues must be consciously produced via users manipulating their avatars

9. Abstract Approach Social information independent of physical analogs –Text (e.g., emote) –abstract graphical representations (e.g., chat circles) Interested in Abstract Approach a. Creates and deploys working systems b. Lack of attention

10. Babble Prototype Two tactics used: a. Textual representation b. Synchronous representation

11. The Babble

12. Social Proxy Schema Size of the audience Amount of conversational activity –More active participants are closer to the center Monitoring activity Minimalist graphical representation of users that depicts their presence and their activities

13. Community Proxy Larger circles represent conversation topics –Filled circles new information Smaller dots represent participants

14. Diachronic Social Proxies

15. Lecture Social Proxy Dots move toward the apex of the wedge with cumulative activity Lecturer is all the way to the front

16. Visualizing Conversation Search for various topics in prior conversations Hits are color coded
