Patent ID: 8864597

Claim:
A weight shift feedback apparatus comprising: a sensing unit configured to sense a weight shift applied to each foot of a user in a golf swing motion of the user; an analyzing unit configured to analyze a weight value applied to each foot of the user with respect to time; a time section determining unit configured to divide each interval between an address point, a middle-of-back swing point, a backswing top point and an impact point of the swing motion into a plurality of equivalent time sections and to determine, for each foot, a time section containing a point where the weight value applied to the foot has the maximum value; and an output unit configured to provide feedback information to the user based on the determined time sections, wherein the time section determining unit determines whether a point where the maximum weight value applied to the right foot is between the middle-of-backswing point and the backswing top point and whether a point where the maximum weight value applied to the left foot is between the backswing top point and the impact point.
