Sketch Recognition for Digital Circuit Design in the Classroom

Digital circuit simulation programs are powerful in education because, unlike paper, they allow students to explore and verify the behavior of a physical system. Unfortunately, learning to navigate the interfaces to these tools can be time consuming and useless from a pedagogical perspective. Our central aim is to build a tool that allows students to sketch circuit schematics on a Tablet PC and then simulate these circuits directly. Our hypothesis is that such a recognition tool will enable students to spend less time fighting with the interface and more time learning the material. We will test this hypothesis by completing a version of this tool for use in Harvey Mudd College’s digital circuit design class, E85, starting in the fall of 2007 1.
