概要/Abstract

We present an early prototype system for editing diagrams by a sketching interface. Although diagrams are efficient media to represent ideas, it is hard for novice users to draw them accurately using conventional software. Also, previous research systems aimed at facilitating diagram editing are not yet mature enough for practical use, in that they are far less expressive than conventional software, and force the user unnatural interaction styles to redeem naive algorithms and interfaces. Therefore, our focus is to introduce a new framework for gracefully supporting many types of geometric primitives and constraints, and handling ambiguous user input. Our current implementation is verified to be sufficient for drawing several complex diagrams, and further improvement is in progress.
