Abstract: A method of analyzing the swing of a sport implement and player over time in three dimensional space involving implanting implement sensors at numerous locations in the implement adapted for measurement of linear motion on three axes and angular motion on said three axes, such as: linear motion inertial sensors; angular motion sensors; axial strain gauges; flexural strain gauges; and torsional strain gauges. Player sensors are set at a number of locations on the player's body, also adapted for measurement of linear motion on three axes and angular motion on said three axes. Data from the sensor suites are communicated via a wireless communications device to a processing unit by: infrared; radio frequency; or the Bluetooth system. Data is processed from the sensor units to derive an output communicated to the player via an interface such as: visual graphics display; text display; sound interface; tactile device; and vibratory device.
