Visualisierungs- und Interaktionsformen für Mathematikanwendungen mit digitalem Papier

Paper has properties that bring, in comparison to computers, advantages in many situations. Writing mathematical expressions on paper is simpler and more intuitive than writing them on a computer. Nevertheless, most mathematical tutoring systems use computers for interaction.
By enhancing paper with thin and bendable EL-Displays, it is possible to create a computerised tutoring system, which utilizes the advantages of the input via paper. After considering the functions a mathematical tutoring system should contain, concepts are presented that show how those functions could be implemented using a pen-and-paper user interface that gives feedback using EL-Displays. Lastly, a prototypical implementation demonstrates how such a system could look like.
