1. A method, comprising:
- generating swing data by a wearable device as the wearable device moves during a predetermined period of time associated with a swing of a golf club, the swing data comprising accelerometer data generated from an accelerometer component of the wearable device and gyroscope data generated from a gyroscope component of the wearable device;
utilizing a processor for;
determining an impact data point of the swing data as an acceleration rate of change of the accelerometer data that exceeds a predetermined maximum threshold within the predetermined period of time, the impact data point associated with a first time interval;
determining a backswing-end data point of the swing data as a minimum value of the gyroscope data associated with a second time interval before the first time interval;
determining a swing-start data point of the swing data associated with a third time interval before the second time interval, by identifying a maximum value of the gyroscope data before the second time interval, andselecting the swing-start data point of the swing data as a value of the gyroscope data that drops below a predetermined minimum threshold before the second time interval;
generating a backswing time and a downswing time associated with the swing of the golf club by analyzing time differences between the first time interval, the second time interval, and the third time interval;
generating a swing tempo using the backswing time and the downswing time; and
integrating individual acceleration values associated with the swing data including each of the swing-start data point, the backswing-end data point, and the impact data point with respect to time to generate velocity vectors for each of a plurality of axes.

14. A method, comprising:
-
determining a first time interval associated with a swing of a golf club when the golf club impacts a golf ball using an accelerometer of a wearable device; determining a second time interval by working backwards in time from the first time interval until the resultant angular rate is half the rate at the point of impact of the first time interval, and continuing to work backwards until the gradient of the resultant angular rate changes direction, the second time interval associated with a backswing of the swing of the golf club using a gyroscope of the wearable device; determining a third time interval by working backwards in time from the second time interval, the third time interval associated with a start of the swing of the golf club using the gyroscope of the wearable device; and generating a tempo of the swing of the golf club by a calculating a difference between at least two of the first time interval, the second time interval or the third time interval. - View Dependent Claims (15, 16)
