Abstract The Problem: Interfaces to mechanical design systems seriously limit the user’s creativity, while drawing on paper does not allow the user to interact with her sketch as a mechanical system. We would like to provide a natural environment for sketching and developing mechanical systems directly on the computer. We are doing this by building an environment that combines the creative freedom of freehand sketching with the technical feedback of viewing and running the sketch as a 2D kinematic simulation. Motivation: The tradeoff between the ease of drawing a mechanical design on paper and the power of representing it on a computer is too great. The unnatural feel of CAD and simulation software inhibits the design process, so engineers design with pencil and paper, rarely transferring their designs to the computer until they are almost complete. An engineer should be able to sketch directly onto the computer, having it feel as natural as sketching on paper, while being able to test the design through simulation at all parts of the design process. The computer should keep track of the engineer’s actions and intentions, not only interpreting the sketch as she draws, but also recording the design process by asking intelligent questions as she sketches. Previous Work: Several others have experimented withsystems that allow users to sketch designs directly onto the computer. Gross has developed the Electronic Cocktail Napkin–a system for sketching conceptual designs on
