One embodiment of the invention provides a kind of method of the customized calibration Touch Screen based on WinCE operating system, is applicable to the electronic installation at least with a Touch Screen, such as personal digital assistant (Personaldigitalassistant, PDA).The relevant informations such as the framework of WinCE operating system and function are open in MSDN (MicrosoftDeveloperNetwork), this instructions is based on the relevant information disclosed by MSDN, and the published relevant public routine of MSDN or common code are not then repeated in this manual.
Figure 2 shows that the process flow diagram of customized according to an embodiment of the invention calibration Touch Screen.Wherein process 2 (S201 ~ 212) is customized according to an embodiment of the invention calibration procedure, registration table 21 and touch-control dynamic base (touch.dll) 22 identical with the registration table 21 in Fig. 1 and touch-control dynamic base (touch.dll) 22.
Step S201 performs a customized calibration procedure for starting, and such as, by this customized calibration procedure called after AppCali.exe, then step S202 shows the customized Calibration interface of AppCali.exe.Step S203 judges whether user presses reference point (provided by calibration interface and be shown on Touch Screen).If so, then step S204 reads the position of touch original value pressed of user; If not, then step S211 judges whether time-out.If time-out, as shown in step S212, terminate customized calibration, if non-time-out, again enter step S203 and judge whether user presses reference point.
If user presses reference point, step S204 reads the position of touch original value that user presses.In one embodiment, the position of touch original value that reading user presses performs by the built-in routine of WinCE, such as, use the TouchPanelEnable function that WinCE is built-in.In another embodiment, can at pattern window events subsystem (Graphics, Windowing, andEventsSubsystem, or claim graphics process window, hereinafter referred to as GWES) set up the function of a reading position of touch original value in the touch-control dynamic base (touch.dll) of process, utilize this function interface can directly read position of touch original value, and the built-in routine as WinCE need not read position of touch original value through several steps.
Then step S205 judges whether position of touch original value is effective value, if effective value then step S206 this effective position of touch original value is recorded as the position of touch sampled value of corresponding reference point.
Step S207 judges whether the position of touch sampled value having gathered all reference point, if the position of touch sampled value of all reference point has gathered all, then step S208 calculates new calibration parameter according to these position of touch sampled values and its calibration reference value.In one embodiment, position of touch sampled value and the new calibration parameter corresponding to its calibration reference value can be calculated according to algorithm disclosed in MSDN.
