Area of Science:

Neuroscience
Computer Science
Education

Background:

Handwriting involves complex motor, sensory, cognitive, memory, and linguistic skills.
Assessing handwriting task difficulty is subjective and relies on expert judgment.

Purpose of the Study:

To develop an objective, machine learning-based approach for evaluating handwriting task difficulty.
To utilize convolutional neural networks (CNNs) for classifying handwriting difficulty levels.

Main Methods:

Two CNN models were developed: single-label and multi-label classification.
Models were trained on a dataset of 117 spatio-temporal features from stylus and hand kinematics for Arabic alphabet letters.
Single-label classification used the mean expert evaluation; multi-label predicted expert assessment distribution.

Main Results:

Both single- and multi-label CNN models achieved high accuracy (96% and 88%, respectively) when using all features.
Hand kinematics features were found to have minimal impact on model performance.

Conclusions:

The proposed CNN models can accurately extract features and predict handwriting task difficulty.
This approach has potential applications in personalized handwriting learning tools and automated quality assessment.
