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)

Whiteboard ExplorationsWhiteboard Explorations

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

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.

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.
