Presentation Transcript

  1. CINCH a cooperatively designed marking interface for 3D pathway selection David Akers 17 September 2014

  2. The Human Brain white matter

  3. Estimated Pathways

  4. Pathway Selection DTI-Query [Akers et al. 2004, Sherbondy, et al. 2005]

  5. Outline • Backgroundbrain imaging and pathway selection • Design ProcessWizard of Oz prototype • The CINCH Systemdemonstration and implementation details • Design Implicationsreflections on design process

  6. Touch

  7. Shape Match

  8. An Interface Design Quandary How to develop a marking language that is both: Useful to scientists (solves their selection problems) Intuitive to scientists (matches their mental model)

  9. Whiteboard Explorations

  10. Wizard of Oz Prototype User mode Wizard mode Designer simulates the effects, using a crude but functional interface Scientists invent their own marking operations

  11. Wizard of Oz Prototype [ Live Demo ]

  12. Marking Operations Invented shape matching touch surface intersection Selection modes: Add, Remove, Intersect

  13. Design Principles Minimality Remove unnecessary parameters whenever possible. Visibility Marks should only affect pathways on the visible side of each cutting plane.

  14. The CINCH Interface [ Demo Video ]

  15. The CINCH Interface

  16. Details: Shape Match 3D pathway (projected) Gestural mark Distance metric: Mean closest points

  17. Details: Grow/Shrink Distance matrix

  18. Related Work 3D modeling interfaces  Sketch[Zeleznik et al. 1996]  Teddy [Igarashi et al. 1999] 3D selection interfaces  SenseShapes [Olwal et al. 1999]  Volume Catcher [Owada et al. 2003] Participatory design  Cooperative Prototyping[Bødker and Grønbæk 1989]

  19. CINCH In Use CINCH was evaluated using: Event logs Screen Captures Interviews Scientists self-reported 2-5 times speedup when using CINCH. CINCH has been adopted and is being used actively.
