Recognition of on-line handwritten mathematical expressions in the E-Chalk system - an extension

E. Tapia, R. Rojas
2005 Eighth International Conference on Document Analysis and Recognition (ICDAR'05)  
This article introduces the new version of our system for the recognition of on-line handwritten mathematical expressions.  ...  The system is embedded as an intelligent assistant in the Electronic Chalkboard (E-Chalk), a system for the live transmition and storage of lectures.  ...  Implementation in the E-Chalk System Java implementation Using the techniques described in the previous section, we wrote a Java library for the recognition of on-line mathematical expressions in E-Chalk  ...

Teaching with an intelligent electronic chalkboard

Gerald Friedland, Lars Knipping, Ra�l Rojas, Ernesto Tapia
2004 Proceedings of the 2004 ACM SIGMM workshop on Effective telepresence - ETP '04  
The E-Chalk architecture is based on the metaphor of the classical chalkboard, enhanced by intelligent assistants running in the background.  ...  One assistant takes care of interpreting the handwritten input of the user. Another is a mathematical formula recognizer which processes handwritten queries for the algebraic server.  ...  ACKNOWLEDGEMENTS The E-Chalk system has been an ongoing project at our lab during the last three years.  ...

The Characteristics of Writing Environments for Mathematics: Behavioral Consequences and Implications for Software Design and Usability [chapter]

Davood G. Gozli, Marco Pollanen, Michael Reynolds
2009 Lecture Notes in Computer Science  
A study is reported that examines how users write mathematical expressions using two graphic based editors: one that is structure-based and one that allows the free-form manipulation of selected symbols  ...  Effective communication and collaboration of symbolic and quantitative knowledge requires the digitization of mathematical expressions.  ...  This greatly reduces the complexity of expression identification as compared to handwritten mathematics.  ...
