Electronic textbooks are offering functional advantages over classic paper textbooks. They provide various features like bookmark, annotation and interactive contents. However, the growth of electronic textbooks has been slow. One of the main reasons is that usability of digital textbooks was often not evaluated carefully. For example, most students frequently highlight text and insert notes in the digital textbooks. Thus, annotating usability should be examined and designed for the reading system in education. The proposing interface was designed to support the students' annotating behavior and learner-centered education.
