Assisted Piano Pedagogy through 3D Visualization of Piano Playing

Having a correct posture at the piano requires a lot of practice to master; however, a visual feedback can help students realize potential problems and adopt a better position when playing the instrument. This paper discusses an innovative application of the techniqes used for the 3D visualization of piano performances in any possible view, with the purpose of comparing them to an ideal piano playing. It includes the capture and reconstruction of the 3D motion and posture of a professional piano player so that it may be compared against the posture and movements of students, by overlaying 2D videos of their recital. Issues with respect to displaying data and adding useful interface features are also discussed. The motion can be adjusted to fit measurements of anthropometrical different students, so that learners can see themselves and better understand what position they should adopt while they are at the piano
