The Trainer Piano actively moves your fingers as you learn how to play. Employing active magnetic force below the keys of a working piano, the Trainer Piano provides users with kinesthetic input that augments their normal motor learning process. By providing a "feel" for what a user is supposed to play, the Trainer Piano minimizes the amount of time necessary to learn new motor patterns and acquire new motor skills. The core idea behind this project lies in the hypothesis that computer-controlled force can be used to teach students how to play an instrument at a faster and more efficient rate than would occur in an unaided learning environment.
