Feedback apparatus and method for improving cocking loosening
First Claim
1. A cocking loosening feedback apparatus, comprising:
- a sensing unit configured to sense three-dimensional direction information of a golf club and of an arm of a user during a golf club swinging motion by the user, the golf club swinging motion comprising a user swing;
an analyzing unit configured to analyze an angle between the golf club and the arm based on the three-dimensional direction information with respect to time to extract a backswing top time, a cocking loosening time and an impact time;
an evaluation variable generating unit configured to generate a cocking loosening evaluation variable of the user based on the difference between the cocking loosening time and the impact time and the difference between the backswing top time and the impact time and a closeness of the cocking loosening time existing between the backswing top time and the impact time to the impact time; and
an output unit comprising a display device or a sound device and configured to provide feedback information to the user based on the cocking loosening evaluation variable,wherein the cocking loosening evaluation variable represents a suitableness of the cocking loosening time of the user swing.

Abstract
A cocking loosening feedback method includes sensing sequential three-dimensional direction information of a golf club and three-dimensional direction information of the arm a user, analyzing the change of an angle between both three-dimensional information with respect to time, generating a cocking loosening evaluation variable based on the difference between the cocking loosening point and the impact point and the difference between the backswing top point and the impact point in the analyzed three-dimensional information, analyzing the evaluation variable based on a predetermined criterion to evaluate the cocking loosening, and providing its feedback information to the user.
