There is an old English folk saying that goes, "If you can't stand the heat, get out of the kitchen." I have a different approach: Do something about the heat. The folk saying would have us accept the poor designs of the world. Why? After all, if people were responsible for the "heat" in the first place, then people should be able to do something about it. Is the kitchen too hot? Redesign it.

Igarashi, Takeo, Matsuoka, Satoshi, Kawachiya, Sachiko and Tanaka, Hidehiko (1997): Interactive Beautification: A Technique for Rapid Geometric Design. In: Robertson, George G. and Schmandt, Chris (eds.) Proceedings of the 10th annual ACM symposium on User interface software and technology October 14 - 17, 1997, Banff, Alberta, Canada. pp. 105-114.

We propose interactive beautification, a technique for rapid geometric design, and introduce the technique and its algorithm with a prototype system Pegasus. The motivation is to solve a problem with current drawing systems: too many complex commands and unintuitive procedures to satisfy geometric constraints. The Interactive beautification system receives the user's free stroke and beautifies it by considering geometric constraints among segments. A single stroke is beautified one after another, preventing accumulation of recognition errors or catastrophic deformation. Supported geometric constraints include perpendicularity, congruence, symmetry, etc., which were not seen in existing free stroke recognition systems. In addition, the system generates multiple candidates as a result of beautification to solve the problem of ambiguity. Using this technique, the user can draw precise diagrams rapidly satisfying geometric relations without using any editing commands. Interactive beautification is achieved by three sequential processes: 1) inferring underlining geometric constraints based on the spatial relationships among the input stroke and the existing segments, 2) generating multiple candidates by combining inferred constraints appropriately, and 3) evaluating the candidates to find the most plausible candidate and to remove the inappropriate candidates. A user study was performed using the prototype system, a commercial CAD tool, and an OO-based drawing system. The result showed that users can draw required diagrams more rapidly and more precisely using the prototype system.
