UC Davis team's piano system animates hands to do-re-mi (w/ video)

(Phys.org)—Researchers from the University of California, Davis, have built an algorithm designed to create a computer-generated animation of piano-playing, showing finger placement and wrist motions. The novel part of all this is that the team's system takes an audio file and creates a piano-playing cartoon to match it, using sound to animate the piano-playing performance. The software can automatically generate a 3-D animation of piano-playing hands based entirely on the music input. Each chord in a piece translates into a finger position and hand motion. They have worked out an algorithm that carefully takes the position of every finger into account, even when that finger is not involved in the next chord.
