Definitions

  • U.S. Patent No. 6,261,102 describes converting the accelerometer output into an audio signal for biofeedback. With the axis of an accelerometer along the axis of the club, it measures the centripetal acceleration and from that value determines the square of the club's angular velocity. A signal proportional to the square of the club's angular velocity is then converted to frequency and fed to the person as an audio signal. Unfortunately, there is a perceived deficiency in its lack of compensating for the effects of gravity and tendency to create unpleasant "chirp like" sounds because of the large speed changes during a golf swing.
  • Another objective of the present invention is to provide improved audio feedback using tonal composition and amplitude characteristics that are pleasing to the ear.
  • the present invention comprises the steps of providing a plurality of sensors mounted along the elongated member for deriving digital signals indicative of motion of the elongated member; processing the signals to eliminate or reduce an effect of gravity, generating a multi bit digital number indicative of the angular velocity raised to a power at at least two positions along the elongated member, and mapping the bits into a plurality of groups each having an associated tonal composition and an amplitude indicative of bit content; synthesizing a sound signal having the tonal composition associated with a group and amplitude indicative of the bit value of the group; and outputting the audio signal.
  • the elongated member is a golf club.
  • Fig. 3 is a sketch used in an analysis of a golf swing using a golf club, but which is equally applicable in the analysis of a swing of any elongated member, such as a tennis racket for example;
  • Fig. 4 is a typical plot of angular velocity squared for the configuration of Fig. 3;
  • synthesizer 340 is programmed by microcontroller 335 to associate each group with a particular MIDI channel.
  • Each MIDI channel is programmed to play a particular chord which in the preferred embodiment, includes two notes known musically as fifths and includes a "root" and its perfect “fifth".
  • the related fifth is of frequency 1.5/ ⁇ -
  • Other harmonic relationships are switch selectable by the panel control 370 in Fig. 6.
  • alternative embodiments may utilize sets of notes with different harmonic relationships and/or sets of notes that are not harmonically related.
  • the preferred instrument for all groups is a rock organ, although another instrument for all groups or different instruments for each group are selectable by the panel control 370.
