  3. CSCW MATRIX Synchronous Asynchronous Colocated Remote Continuous tasks Face to

    face Communication + coordination Remote interactions 3
  4. APPLICATIONS Peripheral displays Shared displays Location tracking 4

  5. Do you use any colocated-asynchronous apps? Can you imagine any

    that might be useful? Which tasks are colocated and async? Ack! Meh. Hrm... 5
  6. PERIPHERAL DISPLAYS Notification Collage Continuous collage of interactive media CollageMachine

    Artful, non-interactive, collage of web media Tickertape One-line streaming text notifications [1], [2], and [3] 6
  7. DEMO Notification Collage 7

  8. PERIPHERAL DISPLAYS CHALLENGES Distraction issues Screen space Integration Privacy concerns

  9. SHARED DISPLAYS Interactive Public Ambient Displays Sharable, interactive public displays

    Dynamo: Interactive Surface Cooperative media exchange Semi-public displays for groups Lightweight group activity, collaboration [4], [5], and [6] 9
  10. SHARED DISPLAYS CHALLENGES Walk up and use Transitions Social issues

    Privacy concerns 10
  11. LOCATION TRACKING SpotON: Wifi 3D location sensing Location sensing for

    context-aware apps LANDMARC: Indoor location sensing Precise indoor location sensing with RFID PARCTAB: Infrared PDA Indoor PDA network with location sensing [7], [8], and [9] 11
  12. LOCATION TRACKING CHALLENGES Position resolution PRIVACY! Hardware costs Context-aware apps

  13. Adoption has been very limited. Why? Would you use a

    shared app in public? How can we approach privacy issues? 13
