     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     In order to work with computer peripheral device, the design of PC games at early stage mostly used a keyboard or mouse as the input source; therefore, a keyboard motion mapping table is designed by software programming in each PC game, in which the keyboard motion mapping table records the correspondence between each motion command of the PC game and any key command on a keyboard. The purpose of the keyboard motion mapping table is to allow the PC game to be able to resolve the motion command issued by the user through a specific key, and then, using the keyboard motion mapping table, to facilitate execution of corresponding motions to the PC game. For example, jump up motion is represented by the Up key (↑) on the keyboard, jump down motion indicated by the Down key (↓), forward motion by the Left key (←) and backward motion by the Right key (→). 
     However, as the drawbacks caused by the keyboard motion mapping table in the prior art set forth hereinbefore, this may largely weaken the entertaining effect created by existing PC games. Besides, since people&#39;s demands may increase and health-care issues may become noticeable in the future, long-term use of the PC game employing existing keyboard motion mapping table by the user can result in specific injuries to user&#39;s body (e.g. fingers), so conventional PC games using the keyboard motion mapping table will inevitably vanish on the market gradually. 
     In order to allow existing popular PC games to survive on the current market, the present invention provides a new mapping tool to substitute the conventional keyboard motion mapping table, and the mapping tool of the present invention can also get rid of limitation in keyboard using a remote device as the input device. 
     Refer conjunctively to  FIGS. 1A and 1B , wherein  FIG. 1A  shows a diagram for an embodiment of the mapping tool according to the present invention, and  FIG. 1B  shows a flowchart for the method of producing the mapping tool according to the present invention. In implementation, the mapping tool set forth hereinafter may be a software application. 
     In  FIG. 1A , the mapping tool  10 ′ according to the present invention is linked with the original keyboard mapping table  10 , wherein the Up key (↑), Down key (↓), Left key (←) and Right key (→) each represents respective direction key on the keyboard, while the alphabets A, A′ indicate jump up motions, the alphabets B, B′ indicate jump down motions, the alphabets C, C′ indicate forward motions and the alphabets D, D′ are for backward motions. Each motion in the mapping tool  10 ′ according to the present invention is not instructed by the keyboard, but enabled by a remote motion signal generated by an external remote device, and then the key press signal on the keyboard is simulated based on the generated remote motion signal so as to replace the effect of the keyboard mapping table  10 , further using the remote motion signal to control the PC game. Details of the method for producing the mapping tool  10 ′ according to the present invention can be shown as  FIG. 1B , and will be explained infra. 
     In the method shown as  FIG. 1B , it generates a plurality of remote motion commands with an external remote device, and creates a remote motion database consisting of the remote motion commands based on the remote motion commands (S 100 ), wherein such remote motion commands may be motions such as, but not limited thereto, swing up, swing down, swing left, swing right, circling, swing upper right to lower left, swing upper left to lower right, stab forward or retract backward, then the mapping tool  10 ′ determines on each remote motion command to define an actual motion. Next, it reads the keyboard mapping table  10  (S 102 ) to further resolve the plurality of keyboard commands and plurality of motion commands in the keyboard motion mapping table  10  (S 104 ); upon completion of the resolution, the mapping tool  10 ′ appreciates the correspondence between the keyboard commands in the keyboard motion mapping table  10  and the motion commands. Subsequently, the mapping tool  10 ′ searches for the corresponding remote motion command based on the motion command (S 106 ), and when the corresponding remote motion command being searched is located, the mapping tool  10 ′ links the remote motion command with the keyboard command included in the keyboard motion mapping table  10 ; as the linking operation is done, the production of the mapping tool  10 ′ is completed (S 108 ). 
     Refer now conjunctively to  FIGS. 2A and 2B , wherein  FIG. 2A  shows a diagram for the architecture of a PC game system having the mapping tool according to the present invention, and  FIG. 2B  shows a diagram for an embodiment of a PC game system having the mapping tool according to the present invention. As shown in  FIG. 2B , the system comprises a host  12 , a remote device  14 , a mapping tool  124  and a screen  16 . The host  12  can be a desktop computer, and consists of a wireless reception device  120 , a mapping tool  124  and at least one PC game  122 . The wireless reception device  120  can be a wireless receiver used to receive the remote motion signal transmitted from the remote device  14 , and the wireless reception device  120  can employ various types of connection interfaces to connect to the host  12 , and such connection interfaces may be a USB interface, IEEE interface or RS-232 interface. The PC game  122  has a keyboard motion mapping table  1220 , the keyboard motion mapping table  1220  recording the correspondence between each motion command of the PC game and any key command pressed on a keyboard. The mapping tool  124  consists of a remote motion resolution section  1240  and a remote motion mapping table  1242 , the remote motion resolution section  1240  being used to resolve the remote motion signal and generating the remote motion mapping table  1242  based on the result of the resolution; meanwhile, the remote device  14  controls the PC game  122  through the remote motion mapping table  1242  and displays the control result on the screen  16 . 
     As shown in  FIG. 2A , the mapping tool  124  can be loaded in the host  12  by at least two fashions. The first approach is to download the mapping tool  124  included in the server host  18  to the host  12  via the network  20 , and the second way is to, with a recordable media  22 , transfer the mapping tool  124  included in the recordable media  22  to the host  12  by manual loading. The said recordable media  22  may be a Compact Disk (CD), a floppy disc or a USB thumb drive. 
     The remote device  14  is used to generate a remote motion signal and transmit it to the wireless reception device  120 . The remote device  14  consists of an inertia sensing module  140 , a sensing signal operation unit  142  and a wireless transmission module  144 . The inertia sensing module  140  can sense the acceleration and angular speed of the remote motion that the user performs through the remote device  14  along X axis, Y axis and Z axis and accordingly generates a signal; in the present embodiment, the remote device  14  is held in hand by the user. The inertia sensing module  140  consists of at least one accelerometer or at least one gyroscope. The sensing signal operation unit  142  is used to receive the acceleration and angular speed of the remote motion generated by the inertia sensing module  140 , and generates the remote motion signal indicating the acceleration and angular speed of the remote motion through computation; the wireless transmission module  144  receives the remote motion signal generated by the sensing signal operation unit  142 , further transmitting such a remote motion signal to the wireless reception device  120  wirelessly (e.g. Bluetooth™, Radio Frequency) 
     Refer now conjunctively  FIGS. 2A ,  2 B and  3 , wherein  FIG. 3  shows a flowchart for the operation method of a PC game using the mapping tool according to the present invention. Initially, the user first loads in at least one PC game containing the keyboard motion mapping table  1220  (S 200 ), the keyboard motion mapping table  1220  recording the correspondence between each motion command of the PC game and any key command pressed on a keyboard. The PC game  122  may be an action game, a heuristic game, an adventure game, a shooting game, a simulation game, a sport game or a strategic game, shown on the screen  16  of  FIG. 2A  as a tennis sport game. Next, it installs the mapping tool  124  into the host  12  (S 202 ), the mapping tool  124  comprising a remote motion resolution section  1240  and a remote motion mapping table  1242 . The mapping tool  124  can be installed in two ways; the first approach is to download the mapping tool  124  included in the server host  18  to the host  12  via the network  20  and then install it, and the second way is to, with a recordable media  22  (e.g. a Compact Disk (CD), a floppy disc or a USB thumb drive), install the mapping tool  124  stored therein into the host  12 . 
     The wireless reception device  120  of the host  12  receives the remote motion signal transmitted by the remote device  14  (S 204 ), the remote motion signal being the signal generated by the acceleration and angular speed of the remote motion that the user performs through the remote device  14  along X axis, Y axis and Z axis, and the remote motion resolution section  1240  of the mapping tool  124  receives the remote motion signal transmitted by the wireless reception device  120 , then the remote motion resolution section  1240  resolve the received remote motion signal (S 206 ). The remote motion resolution section  1240  can be a motion algorithm which resolves the meaning of the remote motion signal based on the rules defined in the motion algorithm, and creates a remote motion database with each of the resolved remote motion signal, in which the remote motion database can be defined beforehand. The mapping tool  124  next separates the motion command and keyboard key command included in the keyboard motion mapping table  1220  to acquire the keyboard key command (S 208 ), and the mapping tool  124  links the resolved remote motion signal stored in the remote motion database with the separated keyboard key command of the keyboard motion mapping table  1220  (S 210 ); upon completion of such a linkage, the production of the remote motion mapping table  1242  is done. The mapping tool  124  simulates the keyboard key signal based on the remote motion signal through the remote motion mapping table  1242  (S 212 ), and at this moment, the user can now operate the PC game using the mapping tool  124  (S 214 ). 
     The mapping tool  124  according to the present invention can replace the conventional keyboard motion mapping table  1220 . It senses the acceleration and angular speed generated by the user&#39;s body with the inertia sensing module  140  of the remote device  14 , thereby creating signals indicating motion states of the user&#39;s body such as rotation, rhyme, swing or force, then transmitting wirelessly the generated remote state signal to the host  12 ; in this way, it is possible to provide the feature of high sensitivity, thus satisfying the demand for real-time control. Through the resolution on the remote state signal performed by the remote motion resolution section  1240  of the mapping tool  124  and then using the mapping tool  124  to operate the PC game, it allows the present invention to meet the requirement for real-time operation of high sensitivity. 
     The present invention provides the following beneficial effects: 
     1. the user, during PC game operations, may be exempted from the limitation of keyboard, better conforming to humanized operation condition and achieving the goal of natural ergonomics, without causing injuries or negative influences on specific portions of user&#39;s body (e.g. fingers). It is also possible to enhance the effect of entertainment by exploiting the features of the mapping tool; 
     2. the game design company needs not to abandon popular PC games developed in earlier days, the user can still play the existing PC game through the mapping tool; hence, the game design company is able to significantly reduce the cost of game development.
