This would still have tactile feedback because you would still be playing a piano. Imagine things like scales being overlaid in a different color where your fingers are supposed to go. Maybe if you hit the wrong key it would flash red. There's all kinds of things you could do.

Ah, so you want this for lessons on a real piano? That seems oddly specific. Far cheaper to get one that has midi capabilities and use any of a number of great apps out there.

I grant that if you can afford a full size piano, you probably don't balk at this thing, though.
