Steppers were designed to get kids up on their feet, moving, and playing with sound and music. An external sensor sandal is worn over a child\’s shoes, noting each footstep, and, in real time, playing back sound effects/music to compliment their movements. Force sensing resistors housed in each sandal wirelessly transmit information back to a computer, which then broadcasts sounds over an FM radio chip that accompany each footstep. Users hear the sounds that they create over an ordinary radio, or through FM headphones.
