What This Document Is
This document presents a focused exploration into the complexities of structural analysis within the field of pen-based user interfaces, specifically as it applies to on-line handwritten mathematical expressions. It delves into techniques for enabling computers to interpret and understand mathematical notation entered by hand, moving beyond simple character recognition to the more challenging task of deciphering the relationships *between* those characters. The work originates from research conducted at the University of Central Florida (CAP 6105 course) and builds upon established pattern recognition principles.
