1. Collaborative Spaces Presented by Jonathan Effrat David Tu

2. Papers Iterative Design of Seamless Collaboration Media Hiroshi Ishii, Minoru Kobayashi, Kazuho Arita Communications of the ACM, Aug 1994 Interacting with Paper on the DigitalDesk Pierre Wellner Communications of the ACM, Jul 1993 Multiple-Computer User Interfaces “Beyond the Desktop” Direct Manipulation Environments Jun Rekimoto CHI 2000: ACM Conference on Human Factors in Computing Systems

3. Seamless Collaboration Media – Ishii et al. Iterative design: TWS-1&2 -> ClearBoard1&2 Seamless integration w/ work practices and between functions Choice of media should be individual Design idea = translucent overlay (images + facial expression) HCI to HHI

4. DigitalDesk – Wellner Computer augmented environment Making the desk more like a workstation Beyond direct manipulation with a mouse – use tactile interactions w/ finger Design idea = desk w/ video projection and video capture Calculator, PaperPaint, DoubleDigitalDesk

5. MCUI - Rekimoto Multiple Computer User Interfaces Design idea = seamlessly transfer information between ubicomp devices Pick-and-drop, digital table, digital wall, hyperdragging Tangible manipulation

6. Mini Activity 1: Seamless Collaboration Media “ClearBoard” Exercise

7. Mini Activity 1: Seamless Collaboration Media “ClearBoard” Exercise Positives of collaboration media Improvements Thoughts on the iterative process in the paper Why is the technology is not in the market? How can it scale to multiple users?

8. Mini Activity 2: Digital Desk How many read CS 376 articles online vs. on paper? When do you choose to use electronic documents vs. paper documents? Can you imagine using DigitalDesk? What are some positives? What are some potential improvements?

9. Mini Activity 3: MCUI

10. Brainstorm Think about situations you wish you could collaborate with others but today’s technology doesn’t facilitate it well How might technologies in these papers help alleviate these? What other technologies might help to solve these?

11. Concluding Remarks What are some of the commonalities & takeaways between the papers

12. Summary Synchronous Asynchronous Co-located Distributed ?? ??
