A Piano Lesson Method Where User Plays The Piano Laying His Or Her Hands On The Image Of A Model Performer'S Hands

We aim that even elderly people with dementia become to live actively with a hobby which provides them a feeling of accomplishment. Playing a keyboard instrument has a high threshold for novice people. Therefore, we proposed a practice method where users can play the piano laying their hands on the image of a model performer's hands. In this paper, we conducted an experiment that ten university students who had no experience or a little experience playing the piano played a musical piece along with the model performance by laying their hands on the CG performer's hands in the mirror. Most students could play the musical piece correctly after playing it only five times. On the other hand, some students hit the wrong keys when the CG model performer hit the key with her mid or ring finger because the model performance was represented like a mirror.
