PenBased Interfaces for Mathematics
Supported by 
 

Welcome to the pages of the Working Group for PenBased Interfaces
for Mathematics at ORCCA,
the Ontario Research Centre for Computer Algebra.
Our objective is to identify, investigate and solve key problems
in developing effective penbased computer interfaces for doing
mathematics. This includes a broad range of questions,
ranging from portability of digital ink architectures, to
semanticallydefined direct manipulation of mathematical expressions.
Penbased interfaces for mathematics can incorporate various techniques
such as menu and palette selection, prompting areas, editing gestures,
dictionarybased methods, as well as hand writing recognition.
Some of the projects underway in our group include:
 Architectures for platformindependence of digital ink applications
 Expression reorganization
 Direct expression manipulation
 Feature identification for character classification in large symbol sets
 Analysis and exploitation of mathematical expression databases
 Mathematical handwriting recognition
 SMW
