Transcript

  • 1. Pick-and-Drop: A Direct Manipulation Technique for Multiple Computer Environments Jun Rekimoto Sony Computer Science Laboratory Inc Oct.15.1997
  • 2. From Single Device UI to multi-Device UI Computer PC PDA PDA Kiosk Wall PC PDA PDA Current PC/GUIs are designed for One-user -- One-computer environment Future Computing Environment must be designed for Multi-user -- Multi-computer environments PDA
  • 3. Limitations of Single-Device GUIs
    • One-to-One dogma
      • Mouse and Keyboard are connected to one computer
      • cf. Paper and Pencil
    • No Direct-Manipulation technique that can interrelate two or more computers
      • e.g., Drag-and-drop between two computers
  • 4. Mouse Jungle
  • 5. Data Copying through Human Body Note: These computers are connected to the Network
  • 6. How people transfer information between nearby computers? % % % % % % A survey conducted on 40 engineers in Sony’s Software Labs.
  • 7. Multi-Computer (Device) UIs
    • No cognitive overload as the number of devices increases
    • Virtual / Physical Characteristics
      • Number, size, orientation, and location of devices
      • Effective combination of a variety of devices
      • Boundaries between computers/devices
        • “ Seamful but beautifully designed seams” [M.Weiser, Invited Talk at UIST94]
    • An Example: Pick-and-Drop
  • 8. Drag&Drop Pick-and-Drop Inter Computer Pick-and-Drop
  • 9. Information transition between virtual and physical spaces Computer Space 1 Physical Space Computer Space 2 Display Surface Pen virtually Carries the data Pick Drop
  • 10. Data Shadow
    • Visual feedback for pen carrying data
    Display Surface
  • 11. Applications of Pick-and-Drop Information exchange between PDAs Picking up information from Kiosk (push media) terminal
  • 12. Wall-sized Display + Palmtop Computer
  • 13. Video
  • 14. System Configuration Network Pen ID = 1 Wall Size Display (or Physical Wall) Desktop Display PDA (Nomadic PCs) ID Data 1 xx.gif Pen ID = 2 Pen Manager
  • 15. Pick-and-Drop between Paper and Computer Tablet Printed Objects Page ID Camera Object ID Page Code Pick Position
  • 16. Discussions
    • Traditional Data Transfer
      • Copy data from C:/ My Document of Machine A to /user/local ….
    • Pick-and-Drop
      • Copy data from here to there
    Symbolic Spatial
  • 17. Summary
    • Multi-Computer (Multi-Device) UI
      • as a new paradigm of direct-manipulation techniques
    • Pick-and-Drop:
      • information transfer technique for multi-device environment
  • 18. Future Work
    • Generalized Pick-and-Drop
      • information exchange between electronic appliance (e.g., VCR), ubiquitous computers, and physical objects (paper, wall, etc.)
    • Pick-and-Drop of active objects
      • e.g., JavaBeans
    • Application to distributed environments
      • Pick-and-drop over video conferencing
  • 19. Pick-and-Drop over ClearBoard ENVISIONMENT
  • 20.  
  • 21. State Transition Diagram PEN-DOWN DRAG PEN-UP MOVE Time Out DRAG PEN-UP MOVE DOWN Time Out DRAG MOVE PICK DROP PEN-UP Time Out
  • 22. Pick-Move, Pick-Copy Move Copy
  • 23. Related Work (1/2)
    • DigitalDesk [Wellner 93]
      • Data transfer from paper to the desk
    • LiveBoard + PARC TAB [Want et.al 95]
      • PARC Tab as a remote pointer for the LiveBoard
    • Graspable UIs [Fitzmaurice et.al 95]
      • Using physical handles (bricks) to manipulate computer objects
  • 24. Related Work (2/2)
    • PDA-ITV [Robertson et.al 96]
      • PDA as a remote controller for the interactive TV
    • PaperLink [Arai et.al 97]
      • Picking up information from paper
    • Ultra Magic Key (UMK) [Usuda et.al 97]
      • TV manipulation using a paper booklet
    • Tangible Bits [Ishii et.al 97]
      • Physical artifact for “Bits” (phicons)
