CoScribe: Using Paper for Collaborative Annotations in Lectures

In a study of notetaking in university courses, we found that the large majority of students prefer the paper medium to the computer for taking notes and making annotations. Based on this finding, we developed CoScribe, a system which supports students in making collaborative handwritten annotations on printed lecture slides. It includes mechanisms for the paper-based sharing and semantic tagging of annotations and slides. Moreover, we present a novel visualization of shared handwritten annotations providing an integrated access to annotations from all learners. A user study indicates that the system efficiently supports student annotation and can be easily integrated into current annotation practice.
