AirTransNote augments activities in classrooms by sharing student notes written on regular paper using wireless communications. AirTransNote uses digital pens to free students from the need to use PCs for note taking. To improve the effectiveness of the system, we used a portable remote controller with an RFID tag reader. Teachers can select notes for students by using the controller as "magic wand." The selection interface is intuitive for both teachers and students. Also, the system can save time for setting up devices before lectures. The system promotes an augmented classroom, enabling interactive lectures in regular classrooms using natural styles.
