I have connected the digital graphics to a flat screen TV mounted just above the piano. Students must keep their eyes up instead of looking at hands. The colorful graphics that cross the screen as the horizontal score rolls by enable the student to see exactly how long each sound is with relation to the others. Two quarter notes can be held to exactly match the length of one half note, and so on. A chord with several notes can clearly be seen as held evenly and noticed when one or more fingers lets go prematurely. A staccato is a tiny dot on the score so that if in a series, one is too long, the indicating line will be longer than the others. The concepts are easily shown in an entertaining way and students are riveted to the bright colors.
