Abstract
When designing electronic circuits, engineers frequently make hand-drawn
sketches of circuits. These are then captured with a computerised design.
This study aims to create an alternative to the common schematic capture
process through the use of an interactive pen-based interface to the
capturing software.
Sketches are interpreted through a process of vectorising the user’s strokes
into primitive shapes, extracting information on intersections between primitives
and using a naive Bayesian classifier to identify symbol components.
Various alternative approaches were also considered.
It is concluded that it is feasible to use a pen-based interface and underlying
recognition engine to capture circuit diagrams. It is hoped that this would
provide an attractive early design environment for the engineer and enhance
productivity.
