What do you do with 27 pairs of used shoes? If you’re like Ingrid Bachmann, you would make them into interactive art.
Each shoe has a toe and heel tap used in tap dancing attached to it. The shoes move or dance independently of each other. The mechanical motion of tapping is created using solenoids (tubular magnetic sensors) that move up and down when activated by a switch. Each switch, 52 in total, is controlled by a microcontroller and software that activates the sequence of the tapping of the shoes.
