Abstract
Metamouse is a demonstrational interface for graphical
editing tasks within a drawing program. The user specifies a
procedure by performing an example execution trace, manipulating
objects directly on the screen and creating graphical tools where
necessary to help make constraints explicit. The system generalizes
the user's action sequence, identifying key features of individual
steps and disregarding coincidental events.
It creates a program with loops and conditional branches as appropriate,
and predicts upcoming actions, thereby reducing the tedium of repetitive
and precise graphical editing. It uses default reasoning about graphical
constraints to make initial generalizations, and enables the user to
correct these hypotheses either by rejecting its predictions or by
editing iconic descriptors which it displays after each action.
