     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0044]    The technical solution of the present invention will be clearly and fully described below with reference to the accompanying drawings. It is obvious that the embodiments to be described are only a part rather than all of the embodiments of the present invention. All other embodiments derived by a person of ordinary skill in the art based on the embodiments of the present invention without carrying out creative activities should fall within the scope of the present invention. 
         [0045]      FIG. 1  is a flow chart of a first embodiment of a virtual icon touch screen application manipulation conversion method according to the present invention. The method includes the following steps. 
         [0046]    S 101 : Run a touch screen application. 
         [0047]    S 102 : Load a mapping configuration file corresponding to the touch screen application, the mapping configuration file including mapping rule information between a touch screen event and a physical input device. 
         [0048]    Specifically, because different touch screen applications correspond to different mapping configuration files, after a touch screen application is started and run, it is required that a system calls a mapping configuration file matching the touch screen application. Suppose a touch screen terminal has a touch screen application A, a touch screen application B and a touch screen application C installed therein, which are respectively corresponding to mapping configuration files 1, 2 and 3, when a user starts and runs the touch screen application A, the system will call the mapping file 1 corresponding thereto, parse a mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application in the mapping configuration file, and load the mapping relationship into a system memory. 
         [0049]    S 103 : Acquire a manipulation instruction of the physical input device, and parse the manipulation instruction according to the mapping rule information in the mapping configuration file, so as to convert the manipulation instruction into a touch screen event. 
         [0050]    Specifically, when a touch screen terminal acquires a manipulation instruction of the physical input device, the system converts, according to the mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application, the manipulation instruction of the physical input device into a touch screen event capable of triggering the touch screen application to execute a corresponding action. When the touch screen terminal obtains manipulation instructions of more than one physical input device at the same time, the system converts current multiple manipulation instructions into the same number of touch screen events according to the mapping rule information. 
         [0051]    S 104 : Manipulate the touch screen application according to the converted touch screen event. 
         [0052]    Specifically, the system distributes the touch screen event to a focus window of the touch screen application, so as to execute corresponding operation. 
         [0053]    It should be noted that, the touch screen application in the present invention refers to a touch screen application having a virtual icon on a program interface, the virtual icon is located at a fixed position of the touch screen, the user can execute a predetermined operation by touching a predetermined virtual icon, and for a touch screen application which has no virtual icon displayed on the touch screen and whose predetermined operation can be executed in a touch screen fixed region, the fixed region is also a virtual icon with a transparent background color. 
         [0054]    The embodiments of the present invention transfers the touch screen operation onto the physical input device through mapping of an external input device and a touch screen event, thereby achieving more precise control and increasing the user&#39;s feel of operation. 
         [0055]      FIG. 2  is a flow chart of another embodiment of a virtual icon touch screen application manipulation conversion method according to the present invention. The method includes the following steps. 
         [0056]    S 201 : Pre-configure a mapping configuration file corresponding to the touch screen application, and save the mapping configuration file. 
         [0057]    Specifically, with respect to characteristics of virtual icons on a touch screen application operation interface, different physical input devices forming mapping with touch screen events are set. If the virtual icon is a joystick, a physical joystick forming mapping with the virtual icon is set; if the virtual icon is a button, a key forming mapping with the virtual icon is set; if the virtual icon is a slider, a pressure sensor key forming mapping with the virtual icon is set. Upon completion of setting, mapping relationship information is saved to a mapping configuration file. 
         [0058]    S 202 : Run a touch screen application. 
         [0059]    S 203 : Load a mapping configuration file corresponding to the touch screen application, the mapping configuration file including mapping rule information between a touch screen event and a physical input device. 
         [0060]    Specifically, because different touch screen applications correspond to different mapping configuration files, after a touch screen application is started and run, it is required that a system calls a mapping configuration file matching the touch screen application. Suppose a touch screen terminal has a touch screen application A, a touch screen application B and a touch screen application C installed therein, which are respectively corresponding to mapping configuration files 1, 2 and 3, when a user starts and runs the touch screen application A, the system will call the mapping file 1 corresponding thereto, parse a mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application in the mapping configuration file, and load the mapping relationship into a system memory. 
         [0061]    S 204 : Acquire a manipulation instruction of the physical input device, and parse the manipulation instruction according to the mapping rule information in the mapping configuration file, so as to convert the manipulation instruction into a touch screen event. 
         [0062]    Specifically, when a touch screen terminal acquires a manipulation instruction of the physical input device, the system converts, according to the mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application, the manipulation instruction of the physical input device into a touch screen event capable of triggering the touch screen application to execute a corresponding action. When the touch screen terminal obtains manipulation instructions of more than one physical input device at the same time, the system converts current multiple manipulation instructions into the same number of touch screen events according to the mapping rule information. 
         [0063]      FIG. 3  is a specific flow chart of step S 204  in  FIG. 2 , which includes the following steps. 
         [0064]    S 2041 : Acquire a hardware number corresponding to the physical input device when detecting an action of the physical input device. 
         [0065]    Specifically, when a system detects an action of the physical input device, the system may immediately query and acquire a hardware number corresponding to the hardware. If the system detects swing of a joystick, the system may immediately query and acquire that a hardware number of the joystick is 11, and then execute next step. 
         [0066]    S 2042 : Query corresponding touch screen geometrical parameter information in the configuration file according to the hardware number. 
         [0067]    Specifically, the mapping relationship in the mapping configuration file is a mapping relationship between geometrical parameter information of the touch screen event at the virtual icon and a hardware number of the physical input device, and geometrical parameter information of the touch screen event, queried by the system by using the obtained hardware number 11 of the joystick, mapped with the hardware number 11 is: center point coordinates (77, 450) and a maximum offset of 50 pixels. 
         [0068]    S 2043 : Convert the action of the physical input device into a touch screen event. 
         [0069]    Specifically, the physical joystick is an analog input device, capable of inputting displacement information in horizontal and vertical directions, and in order to achieve conversion between a joystick and a virtual joystick touch screen event, it is necessary to match analog input of the physical joystick with pixel movement of the virtual joystick. For example, a maximum offset of the physical joystick is 65535 scales, a maximum offset of the virtual joystick is 50 pixels, and if the two offset parameters are proportional, it can be achieved that physical joystick input is converted into virtual joystick pixel output, so as to determine coordinates of a center point of the virtual joystick, and when the physical joystick swings to left by a half of a full scale, the corresponding virtual joystick touch screen event is a touch screen event that a finger holds the coordinates (77, 450) of the touch screen to offset 25 pixels to the left. 
         [0070]    S 205 : Manipulate the touch screen application according to the converted touch screen event. 
         [0071]    The embodiment of the present invention does not need to use an application interface, but can transfer a touch screen operation onto a physical input device by only setting a mapping relationship between the physical input device and the touch screen, thereby achieving more precise control and increasing the user&#39;s feel of operation. 
         [0072]      FIG. 4  is a structural view of a first implementation of a touch screen terminal according to the present invention, and the touch screen terminal includes the following modules. 
         [0073]    A starting and running module  41  is used for running a touch screen application. 
         [0074]    A loading and parsing module  42  is used for loading a mapping configuration file corresponding to the touch screen application, the mapping configuration file including mapping rule information between a touch screen event and a physical input device. 
         [0075]    Specifically, because different touch screen applications correspond to different mapping configuration files, after the starting and running module  41  runs a touch screen application, it is required that a system calls a mapping configuration file matching the touch screen application. Suppose a touch screen terminal has a touch screen application A, a touch screen application B and a touch screen application C installed therein, which are respectively corresponding to mapping configuration files 1, 2 and 3, when the starting and running module  41  runs the touch screen application A, the loading and parsing module  42  will call the mapping file 1 corresponding thereto, parse a mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application in the mapping configuration file, and load the mapping relationship into a system memory. 
         [0076]    An acquisition and conversion module  43  is used for acquiring a manipulation instruction of the physical input device, and parsing the manipulation instruction according to the mapping rule information in the mapping configuration file, so as to convert the manipulation instruction into a touch screen event. 
         [0077]    Specifically, when the touch screen terminal acquires a manipulation instruction of the physical input device, the acquisition and conversion module  43  converts, according to the mapping relationship between a physical input device and a touch screen event at a virtual icon of the touch screen application, the manipulation instruction of the physical input device into a touch screen event capable of triggering the touch screen application to execute a corresponding action. When the touch screen terminal obtains manipulation instructions of more than one physical input device at the same time, the acquisition and conversion module  43  converts current multiple manipulation instructions into the same number of touch screen events according to the mapping rule information. 
         [0078]    An event execution module  44  is used for manipulating the touch screen application according to the converted touch screen event. 
         [0079]    Specifically, the event execution module  44  distributes the touch screen event to a focus window of the touch screen application, so as to execute corresponding operation. 
         [0080]    It should be noted that, the touch screen application in the present invention refers to a touch screen application having a virtual icon on a program interface, the virtual icon is located at a fixed position of the touch screen, the user can execute a predetermined operation by touching a predetermined virtual icon, and for a touch screen application which has no virtual icon displayed on the touch screen and whose predetermined operation can be executed in a touch screen fixed region, the fixed region is also a virtual icon with a transparent background color. 
         [0081]    The embodiment of the present invention transfers the touch screen operation onto the physical input device through mapping of an external input device and a touch screen event, thereby achieving more precise control and increasing the user&#39;s feel of operation. 
         [0082]      FIG. 5  is a structural view of a second implementation of a touch screen terminal according to the present invention. It can be seen from  FIG. 5  that, this embodiment also includes a starting and running module  41 , a loading and parsing module  42 , an acquisition and conversion module  43  and an event execution module  44 , and in addition, further includes:
       a pre-configuring and saving module  45 , for pre-configuring a mapping configuration file corresponding to the touch screen application, and saving the mapping configuration file.       
 
         [0084]    Specifically, with respect to characteristics of virtual icons on a touch screen application operation interface, the pre-configuring and saving module  45  sets different physical input devices forming mapping with touch screen events. If the virtual icon is a joystick, the pre-configuring and saving module  45  sets a physical joystick forming mapping with the virtual icon; if the virtual icon is a button, the pre-configuring and saving module  45  sets a key forming mapping with the virtual icon; if the virtual icon is a slider, the pre-configuring and saving module  45  sets a pressure sensor key forming mapping with the virtual icon. Upon completion of setting, the pre-configuring and saving module  45  saves mapping relationship information to a mapping configuration file. 
         [0085]    The acquisition and conversion module  43  includes:
       a number acquisition unit  431 , for acquiring a hardware number corresponding to the physical input device when detecting an action of the physical input device;   a query unit  432 , for querying corresponding touch screen geometrical parameter information in the configuration file according to the hardware number; and   a conversion unit  433 , for converting the action of the physical input device into a touch screen event.       
 
         [0089]    Specifically, a racing game controlled by a key is used for description. Referring to  FIG. 6 , a rectangular region  61  is a game brake control region, and a car can be braked immediately when any point in the region is clicked. A rectangular region  62  is a game display region, a rectangular region  63  is a game acceleration/deceleration control region, clicking pixel points in the rectangular regions sequentially from top to bottom can control the speed of the car from slow to fast,  64  indicates a physical key A,  65  indicates a pressure sensor key B, the physical key A is mapped with a touch screen event at the rectangular region  61 , and the pressure sensor key B is mapped with a touch screen event at the rectangular region  63 . 
         [0090]    The acceleration/deceleration control region controls a continuously changing process, at this time, a key with a sensor is used for mapping, and because the sensor is generally used for detecting an analog signal, that is, a continuously changing signal, a continuously changing signal actually input externally can be converted into a continuously changing process of pixels on the touch screen. The pressure sensor key B is used to map the touch screen event of the acceleration/deceleration control region, and a common key A is used to map the brake control region. 
         [0091]    When the key A is pressed, the system generates an interruption, the number acquisition unit  431  acquires a key value 14 corresponding to the key A, the query unit  432  finds corresponding touch screen geometrical parameter information in the mapping configuration file according to the key value 14, where the touch screen geometrical parameter information is: center point coordinates (28, 228) and a maximum offset of 0 pixel, the conversion unit  433  converts the pressing action of the key A into a single-click event at the touch screen (28, 228), and the center point coordinates are coordinate values of any point in the brake control region. 
         [0092]    When the key B is pressed, the system generates an interruption, the number acquisition unit  431  acquires a key value 15 corresponding to the key B, the query unit  432  finds corresponding touch screen geometrical parameter information in the mapping configuration file according to the key value 15, where the touch screen geometrical parameter information is: center point coordinates (763, 2), a maximum offset of −470 pixels, and an offset angle of −270 degrees, the conversion unit  433  converts the pressing action of the key B into a touch screen event along a y-axis negative direction taking the touch screen coordinates (763, 2) as a starting point. The maximum scale value of a pressure sensor is M, the maximum offset pixel in a y-axis negative direction of the acceleration/deceleration control region is N, a proportional coefficient is k=N/M, suppose an analog input by the pressure button is P, the corresponding pixel offset on the touch screen is k·P pixels, where M, N, P are integers, and at this time, the conversion unit  433  converts the pressing action of the key B into a touch action at touch screen coordinates (763, 2+k·P). 
         [0093]    The embodiment of the present invention does not need to use an application interface, but can transfer a touch screen operation onto a physical input device by only setting a mapping relationship between the physical input device and the touch screen, thereby achieving more precise control and increasing the user&#39;s feel of operation.
