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
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
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
MCUI - Rekimoto
   Multiple Computer User Interfaces
   Design idea = seamlessly transfer
    information between ubicomp devices
   Pick-and-drop, digital table, digital wall,
    hyperdragging
   Tangible manipulation
Mini Activity 1:
Seamless Collaboration Media
   “ClearBoard” Exercise
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?
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?
Mini Activity 3:
MCUI
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?
Concluding Remarks
What are some of the commonalities &
 takeaways between the papers
