Generating the human piano performance in virtual space

Piano performance requires dynamic hand-finger movements. Since the movements are constrained due to the anatomical components, such as tendons and skeletons, the movements in piano performance are quite complicated, and that makes it difficult to master this instrument. It is clear that to observe good examples of performance is helpful for learning. For this purpose, we develop a system that shows us the most appropriate example of performance for any given scores. In this article, we discuss several algorithms used in our system, which generate a kind of optimal movements of hands and fingers at the piano performance.
