Abstract
In the classroom, music teachers think the content of the lesson from scratch every time, and teach music to kids with a textbook and real musical instrument. As a result, teachers spend a many time preparing for classes, and there is a problem that the burden on preparing for class increases. In order to achieve this goal, we have developed a serious game named “XyloStories” in 2019. But in “XyloStories”, the performance of the system was not adequate, which means that the latency of the key touch to the movement is significant. In order to solve this problem, we developed “XyloStories2” which improving the performance of “XyloStories”. This serious game can reduce the burden on the teacher with combine game and musical instrument by through the Arduino.
