Abstract
Technique of virtual reality has been becoming popular in various fields including education because of its remarkable technique progress. There are the three useful elements of “presence”, “interaction” and “autonomy” in realizing the virtual reality. Here, we are focusing on the “presence” in constructing a simple supporting system for calligraphy education. We take advantage of the virtual image with reality to use as an educational interface because the virtual image and the real image are overlapped by showing the visual scene in the system.
It is general that the unity of the virtual image and the real image has been processed as the stationary pictures by using “See-through HMD” and so on. In this paper, by using half mirror in stead of using the HMD with restraint, we are released from its restrainable sense. The virtual image and the real image are laid to overlap as the mobile pictures. The virtual hand replays the character inputted on the tablet by the excellent calligrapher. A calligraphic trainee is practicing overlapping the virtual hand which is reflected at the half mirror, while the trainee is doing the character on the tablet in the handwriting. The trainee is repeatedly practicing with feedback and is getting better in handwriting the character. It is shown in the good expermental results that the system has a proven effectiveness.
