Abstract:
1. A computer-enabled method of analyzing a swing of a sporting equipment using a terminal device that is configured to wirelessly receive sensor data from an equipment-mounted motion sensor, the method comprising: receiving, from the motion sensor over a wireless communication channel, a plurality of sensor data, wherein a sensor datum of the plurality of sensor data comprises information representing acceleration of the equipment-mounted motion sensor; determining when the sporting equipment is in an address position, based on at least a portion of the received plurality of sensor data, wherein the address position is a starting position of the swing; determining, from at least a portion of the received plurality of sensor data, a vector indicating a gravitational acceleration direction with respect to a first coordinate system, determining a target line for the sporting equipment at the address position, by computing the outer product of the vector indicating the gravitational acceleration direction and a vector representing the z-axis, characterizing a path of a swing of the sporting equipment based on the target line.
