Abstract
This paper describes an innovative e-learning project which is the
development of a digital workbook that helps teaching handwriting at
school. In this work, we propose a new qualitative and quantitative
analysis process of cursive handwriting. This process detects
automatically mistakes, gives a real-time feedback and helps teachers
evaluate children’s writing skills. The main aim of this digital
workbook is to help children learn how to write correctly. The proposed
process is composed of five main criteria: shape,direction, stroke
order, position respect to the reference lines and kinematics of the
trace. It analyzes the handwriting quality and gives automatically
feedback based on the Beta-Elliptic Model using similarity detection
(SD) and dissimilarity distance (DD) measure. Our work apprehends
dynamic and visual representation of the acquired traces and selects
efficient features adapted to various handwriting styles and multiple
script languages such as Arabic, Latin, digits, and symbols drawing. It
demonstrates that beta-elliptic is not only a model for segmentation and
recognition but also a tool to evaluate handwriting. Our application
offers two interactive interfaces respectively dedicated to learners,
and experts or teachers who can adapt it easily to the specificity of
each child. The validation of the proposed system is done on a database
collected in Tunisia primary schools with 400 children. Experimental
results show that the efficiency and robustness of our suggested
framework that do help teachers and children by offering positive
feedback throughout the handwriting learning process using tactile
digital devices.
