Resolving Ambiguities to Create a Natural Computer-Based Sketching Environment
Speaker: Christine Alvarado , MIT AI Laboratory
Current computer-based design tools for mechanical engineers are not tailored to early stages of design. Most designers use pencil and paper at first, and input their design into CAD systems only after it is nearly complete. To bridge the gap between these two stages, our goal is to create a kind of magic paper: a computer-based sketching environment that feels as natural as sketching on paper, but unlike paper, understands a mechanical engineer's sketch as he draws it. An important step toward realizing this goal is resolving ambiguities in the sketch, such as determining whether a circle is a body or a pin joint, as the user draws without interfering with the design process. I present a method for resolving ambiguities in mechanical sketches and a system that uses this method to interpret mechanical sketches as an engineer draws them.
