Extraction of Writing Carefulness from Online Handwritten Data

In order to improve the e ectiveness of sharing notes on peer learning, students need to improve the presentation of their handwritten notes, because carefully written notes are more accessible for other students and reduce irrelevant, careless mistakes. To facilitate improvements in note-taking, we considered a simple metric that determine how carefully the notes were written, and checked the metric by using students note taken at a real lecture. The result showed some correlations among the metric and the writing time.
