The EduBuzzer is a device designed to provide an additional channel of communication between students and teachers. It is a handheld box with four buttons that is in contact with the teacher's laptop or presentation station, from where he can initiate different modes (called "games") like voting, electronic raising of hands or team assignments. The devices themselves are generic enough that additional games can be implemented easily in JavaScript. | The EduBuzzer is a device designed to provide an additional channel of communication between students and teachers.

: While the students hand out the buzzers, she hooks his laptop up to the beamer, connects the EduBuzzer base station and explains the basics of the game. She starts the appropriate application, selects a well-known song and starts it. While the students carefully listen not to miss a beat and watch the scrolling tones, she can correct the last lesson's tests. | : While the students hand out the buzzers, she hooks his laptop up to the beamer, connects the EduBuzzer base station and explains the basics of the game.
