Pen-Based Interfaces for Mathematics Ontario Research Centre for Computer Algebra Supported by          Overview Welcome to the pages of the Working Group for Pen-Based 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 pen-based computer interfaces for doing mathematics. This includes a broad range of questions, ranging from portability of digital ink architectures, to semantically-defined direct manipulation of mathematical expressions. Pen-based interfaces for mathematics can incorporate various techniques such as menu and palette selection, prompting areas, editing gestures, dictionary-based methods, as well as hand writing recognition. Some of the projects underway in our group include: Architectures for platform-independence 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 Resources Publications Presentation Materials Demos Related links Ontario Research Centre for Computer Algebra MathML Project at ORCCA Mathematical Notation Selection Tool Mathematical Format Converters: TeX - MathML MathML - OpenMath Events Conferences PenMath 2009 3rd International Workshop on Pen-Based Mathematical Computation at the Conferences on Intelligent Computer Mathematics, CICM 2009 July 8-9, 2009, Grand Bend, Canada CMDE 2006 Communicating Mathematics in Digital Era Session on Pen-Based Interfaces for Mathematical Documents August 15-18th, 2006, Aveiro, Portugal CAIMS-MITACS 2006 Joint Annual Conference Poster & Demo Exhibits June 16-20th, 2006, Totonto, Canada ACA 2005 Special Session on Pen-Based Mathematical Computing July 31-August 3, 2005, Nara, Japan International Conference on Document Analysis and Recognition (ICDAR), Korea, 2005.
