Abstract
An electronic book system provides interfaces particularly suited to students' use of textbooks. Annotations are displayed and hidden using specific gestures and through selective movement of the reader as sensed by its accelerometer. Motion of the electronic book reader below a threshold speed causes a change in display of user-selected content in a first manner and motion above the threshold speed causes a change of display in a second manner.
