Abstract
An electronic book system provides interfaces particularly suited to students' use of textbooks. A finger press on a touch screen produces a contextual menu with user choices that relate to where the finger was pressed or what the user was recently doing with the book. A student provisionally navigates through a book by a specific gesture which, when it stops, returns the user to the previous position in the book. Annotations are displayed and hidden using specific gestures and through selective movement of the reader as sensed by its accelerometer.
