Development of a Piano Practice System for Beginners Using Mixed Reality Technology

In this study, we have developed a piano practice system for beginners by fusing mixed reality and augmented reality technologies. This system allows piano learners to practice at their leisure. In this system, a virtual piano is superimposed on a real world piano, and users can practice the piano along with the virtual notes. The operability, visibility, functionality, relevance, effectiveness, and applicability of this system have been evaluated on 30 subjects. As a result, we were able to obtain high evaluations in many items.
