     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings. 
         [0017]    With reference to  FIG. 1  for a functional block diagram of an evaluation device in accordance with a preferred embodiment of the present invention, the target object position evaluation device used at sport events uses an evaluation device  10  to evaluate a hit between a shooting object and a target object, and the evaluation device  10  comprises: a CPU  11 , a GPS module  13 , an environment detection unit  14 , a memory  15 , a display device  17 , an input device  19  and a voice output device  21 .

In a preferred embodiment of the present invention, the environment detection unit  14  includes a wind speedometer  14   a  and a wind direction meter  14   b  for outputting wind speed information and wind direction information to the CPU  11 . In a preferred embodiment of the present invention, the environment detection unit  14  includes the wind speedometer  14   a  or the wind direction meter  14   b  exclusively. The wind speedometer  14   a  is a thermal sensing type wind speedometer or a thermal bulb type wind speedometer that can be cooled by wind to produce a change of resistance, or a vane type wind speedometer that measures the wind speed by counting the number of rotations of the vane. The wind direction meter  14   b  is composed of a pointing device that changes its pointing direction according to a wind direction and a varistor whose resistance value varies with different wind directions for obtaining an indication of a wind direction. The memory  15  is electrically coupled to the CPU  11  for storing coordinates information of the target object, physical information of the shooting object, and an evaluation program. The evaluation program is provided for operating the CPU  11  to perform a mechanical estimation to the coordinates information of the evaluation device  10 , the environmental information, the coordinates information of the target object, and the physical information of the shooting object. Such estimation is performed according to a formula related to the laws of motion and written into the evaluation program. The coordinates information can be used for estimating the distance between the evaluation device  10  and the target object, and then using the physical information such as the weight of the shooting object to estimate a shooting angle and an initial shooting speed according to the formula related to the laws of motion. The environmental information mainly includes a revised item such as wind direction and wind speed that will deviate the flying of the shooting object, and air pressure that will increase or shorten the flying distance of the shooting object, wherein the revised item can be revised by a real-time computation or by a lookup table. After the revision takes place, the revised item will be able to evaluate and provide better shooting information and finally output an evaluation result to the CPU  11 .

If the environmental information includes the wind direction information only, then the evaluation result can be a shooting location; if the environmental information includes the wind speed information only, then the evaluation result can be an initial shooting speed. The physical information of the shooting object can be the weight of the shooting object estimated by the density and volume of the shooting object. 
         [0022]    The display device  17  is electrically coupled to the CPU  11  for displaying the evaluation result outputted by the CPU  11 . In a preferred embodiment of the present invention, the display device  17  is a liquid crystal display device having a graphic interface for displaying various types of information.

In a preferred embodiment of the present invention, the input device  19  is a touch panel integrated with the display device  17  for facilitating user&#39;s operations. 
         [0024]    The voice output device  21  is electrically coupled to the CPU  11  for playing the evaluation result outputted by the CPU  11  by using a voice guidance method. Therefore, users no longer need to view the display device  17  downward to obtain the shooting information required for hitting the target object by the shooting object anymore. 
         [0025]    The present invention can be applied in various sport events such as golf, archery and shooting, etc. The application of the invention applied in golf is used for illustrating the operation of the evaluation device  10  as follows. 
         [0026]    An evaluation device  10  is used at a golf sport to perform a hit evaluation between a golf ball and a golf hole target, and the evaluation device  10  comprises: a CPU  11 ; a GPS module  13 , electrically coupled to the CPU  11 , for receiving a satellite signal to position the evaluation device  10 , and outputting coordinates information of the evaluation device  10 ; an environment detection unit  14 , electrically coupled to the CPU  11 , for outputting detected environmental information; a memory  15 , electrically coupled to the CPU  11 , for storing coordinates information of the golf hole target, physical information of the golf ball and an evaluation program, wherein the evaluation program is provided for operating the CPU  11  to estimate the coordinates information of the evaluation device  10 , the environmental information, the coordinates information of the golf hole target and the physical information of the golf ball and driving the CPU  11  to output an evaluation result; and a display device  17 , electrically coupled to the CPU  11 , for displaying the evaluation result; wherein the evaluation result is the ball striking information required for hitting the golf hole target by the golf ball.

         [0029]    In Table 1, the predetermined flying distance refers to the distance between the current ball striking point and the golf hole target, and the wind direction is in the same direction of the flying direction provided that the wind speed is 1 (m/s), and a revised distance made in these conditions is used for the illustration. If the predetermined flying distance is equal to 140 yards, then the revised flying distance is equal to 143.5 yards provided that the wind direction is the same as the flying direction and the wind speed is equal to 1 (m/s). Therefore, a user has to strike a golf ball to a distance of 136.5 yards to reach the golf hole target. Therefore, the evaluation result outputted by the evaluation device  10  will recommend the user to use an appropriate golf club for striking the golf ball to a distance of 136.5 yards, and an appropriate force (such as strong, medium, and weak as classified for different striking distances of various golf clubs) applied onto the golf club. The memory  15  also stores a corresponding relation of various wind directions provided for the evaluation device  10  to output an appropriate evaluation result. 
         [0030]    With reference to  FIG. 2  for a flow chart of an operation of an evaluation device used in a golf sport in accordance with a preferred embodiment of the present invention, Step S 21 : the coordinates information of all golf hole targets of a golf court are inputted into the evaluation device  10  in advance, and the coordinates information are stored into the memory  15 , such that if a striker is standing at a ball striking position, the GPS module  13  will be able to obtain the coordinates information of the ball striking position (which is also the coordinates information of the evaluation device  10 ). 
         [0031]    Step S 22 : the distance between the ball striking position and a selected golf hole target is carefully calculated by the CPU  11  according to the coordinates information of the ball striking position and the coordinates information of the golf hole target. 
         [0032]    Step S 23 : the wind speed information and the wind direction information at the ball striking position collected by the wind speedometer  14 a and the wind direction meter  14   b  of the evaluation device  10  are inputted into the CPU  11 . 
         [0033]    Step S 24 : the evaluation program stored in the memory  15  is operated to drive the CPU  15  to perform a mechanical estimation of different information and output an evaluation result. 
         [0034]    Step S 25 : the evaluation result is outputted from the display device  17  or the voice output device  21 . 
         [0035]    Therefore, the application of the present invention applied in a golf sport takes the factors including the wind speed and the wind direction that will affect the flying trajectory of the golf ball into consideration to provide better ball striking direction and ball striking force to a striker, wherein the ball striking force refers to the distance between the golf club and the golf hole target recommended to the striker. Since different types of golf clubs come with different loft angles and maximum ball striking distances, therefore the striker can strike a golf ball to a different extent according to the distance between the golf club and the golf hole target. 
         [0036]    While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
