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 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. | ||

: 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.

The EduBuzzer project includes everything from the application framework running on the teacher's workstation to the hardware of the EduBuzzer. All of it can be downloaded from our [[HSC2011/Download instructions|download area]]. | |||
* The [[HSC2011/Software|software]] | |||
** The [[HSC2011/Software#JavaScript|games]] themselves run in a modern browser and can be extended using JavaScript; a library spares them the details of radio communication. | |||
** A middleware called [[HSC2011/Software#Ygor|Ygor]] serves both the game software, as a persistence layer for games, and as a media converter to the base station connected via USB. | |||
** The [[HSC2011/Software#Firmware|firmware]] flashed on the EduBuzzers and the base station reacts on hardware events and commands received over radio. If a game requires more complex actions on the hardware like animations over the LEDs, LED fading or music to be played, the firmware can run custom code in a [[HSC2011/Software#VM|virtual machine]]. | |||

** The EduBuzzers themselves are handed out to students. | |||
** The base station, which is actually another EduBuzzer with a USB adapter attached, can be attached to any PC and contains all the software. | |||
