Pegasus

Abstract
Pegasus is a prototype drawing system for rapid geometric design. Using Pegasus, a user can construct precise geometric diagrams easily without struggling with complicated editing commands. Two novel interaction techniques are introduced: interactive beautification and predictive drawing. Interactive beautification receives the user's free stroke input and beautifies it by considering possible geometric constraints among segments by generating multiple candidates to prevent recognition errors. Predictive drawing predicts the user's next drawing operation based on the spatial relationship among existing segments on the screen.
