Interesting. An extension of this would be to use an angle sensor that will control a tone generator like the auditory gimmick. When the tape is straight ahead or behind the tone would be at it's lowest. If you got off line the tone would increase. You could easily tell which way to turn by experimentally turning your head to see which way you are off.
