For golfers, golfers should include drivers, fairway woods, irons, wedges (pitching / sand / robe) and putters.

Especially putters are one of the most important golf clubs used to strike golf balls with a golf ball on the green.

The main function of the putter is to aim the cup, which is the target point on the green, and there are L-shaped putter, T-shaped putter, pin type putter and putty type putter.

This is a method in which one ball is uniformly directed toward the target device In order to determine the cause of a golf ball hit or to move to the left or right due to the impact motion, it is easy to determine whether the problem is caused by the balance of the putter striking or the condition of the golfer In addition to not being able to grasp, it is also difficult to grasp the sense of balance of consistent putter strike because it is difficult to grasp the cause even if the golf ball is well advanced as intended.

One example of a recently proposed putter is a putter in which a line of sight of a golf ball and a line of sight of the head, which is the upper end of the putter head, are arranged at right angles to the putter face, Since a putter having a pattern of a golf ball is proposed, it is required to develop a technique for performing a golf practice using a putter using a line of sight in the technical field.

For example, the module may mean a logical unit of a predetermined code and a hardware resource for executing the predetermined code, and it does not necessarily mean a physically connected code or a kind of hardware. Can be easily deduced to the average expert in the field of < / RTI >

The impact sensing means 21 controls the I / O interface 10 to receive an impact sensing signal, which is a type of sensing data, from one of the piezoelectric element arrays 114c including the reference piezoelectric element RP.
