Abstract
Today, the technique of virtual reality has become popular in various fields because of its technical progress. We focused on ‘presence’ - one of the three elements of virtual reality, and constructed a simple supporting system for piano education. The virtual world and the real world are overlapped by showing the visual information in this system. The purpose of this system is to use the realistic virtual image as an interface (or tool) of education.
The unity of the virtual image and the reality has been done with standing pictures by using, for example, ‘See-through HMD’. In this research, however, we overlapped the virtual image and the real world with moving pictures. The overlapping is accomplished not by using HMD, but by using a half mirror. The virtual hands can automatically play a tune from a score so that learners can choose what they like without instructors. This is one example of the system which has a proven effectiveness.
