1. A wrist-worn bowling monitoring device for monitoring the bowling motion of a bowler, comprising:

  • sensor means for sensing the accleration of the device in three orthogonal axes of motion and providing data representative of the acceleration of the device in the three axes of motion;

    first computation means for computing values equal to the square root of the sum of the squares of the acceleration data of each direction;

    first comparison means for comparing each of said computed values the to a predetermined threshold;

    second computation means for adding each computed value which exceeds the predetermined threshold to provide a total;

    second comparison means responsive to the first comparison means for comparing the computed total to a predetermined range if a computed value is found to be less than the threshold;

    signal means for providing a first signal if the computed total exceeds the predetermined range and a second signal distinguishable from the first signal if the computed total is less than the predetermined range; and

    bowler operable input means for inputting a desired total value and a window value, wherein the predetermined range is defined as the desired total value less one-half the window value to the desired total value plus one-half the window value.
