Estimating the Care with which Notes are Written from Online Handwritten Character Data

In our previous work, we developed AirTransNote, a student note-sharing system that facilitates collaborative and interactive learning during regular lectures in conventional classrooms. Because taking notes on paper is a regular activity, our system does not impose an extra burden on students who share notes. However, in order to improve the effectiveness 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 applied a set of metrics that determine how carefully the notes were written, and propose a system that provides feedback to students about how carefully they are writing notes.
