Abstract (en)
[origin: WO2006041449A1] A biofeedback system including an elongated member, for feeding back sounds indicative of swing tempo of the elongated member is provided. The system comprises a plurality of acceleration measuring devices adapted to measure accelerations at a plurality of locations along the elongated member; a first microcontroller for processing the measured acceleration signals to reduce effects of gravity and forming a digital number related to an angular rotational speed raised to a power; said digital number comprising a plurality of bits; a second microcontroller for receiving the digital number and associating the bits with a plurality of groups each having an associated tonal composition and amplitude value indicative of bit content and for forming commands indicative of the tonal composition and amplitude value; and a synthesizer responsive to commands and producing an audio signal; and means for outputting the audio signal.
