This is cool, but I'm having a hard time seeing this working in a real product. Guitarists have been using their picking hand or pedal controls since the beginning of the electric guitar without much fuss or concern. I also thought pie menus died off because everyone decided they were too limited, hard to understand, and overall annoying regardless of the input method.
