具触控式屏幕的电子装置及其显示控制方法Electronic device with touch screen and display control method thereof

技术领域technical field

本发明是有关于一种电子装置及其显示控制方法，且特别是有关于一种具触控式屏幕的电子装置及其显示控制方法。The present invention relates to an electronic device and its display control method, and in particular to an electronic device with a touch screen and its display control method.

背景技术Background technique

由于科技的进步，现在电脑的操作系统已经能够支持触控式屏幕，因此，使用者可以利用手来取代电脑的鼠标来进一步的控制电脑系统。Due to the progress of science and technology, the operating system of the computer is able to support the touch screen. Therefore, the user can use the hand to replace the mouse of the computer to further control the computer system.

然而，由于现今视窗操作系统无法将触控式屏幕上特定区域局部放大，并且在局部放大的区域中进行编辑或者点选。因此，使用者在操作上会觉得很不方便。However, due to the fact that the current Windows operating system cannot partially enlarge a specific area on the touch screen, and edit or click in the partially enlarged area. Therefore, the user will feel very inconvenient in operation.

以编辑功能为例，请参照图1a，其所示为视窗操作系统上的图形编辑软件操作示意图。此视窗操作系统于触控式屏幕100上可显示出操作系统的工具栏110，而工具栏110上有多个用户接口，例如开始按钮112、以及网络状态图形114。而在操作系统上执行图形编辑软件120(例如小画家)，此图形编辑软件120的视窗上也有相对应的用户接口，例如结束按钮122、缩放按钮124、最小化按钮126。Taking the editing function as an example, please refer to FIG. 1 a , which is a schematic diagram of the operation of the graphics editing software on the Windows operating system. The Windows operating system can display atool bar 110 of the operating system on thetouch screen 100 , and there are multiple user interfaces on thetool bar 110 , such as astart button 112 and anetwork status graphic 114 . While executing the graphics editing software 120 (such as Little Painter) on the operating system, there are also corresponding user interfaces on the window of thegraphics editing software 120, such as anend button 122, azoom button 124, and aminimize button 126.

假设用户需要在操作接口上描绘一个“w”字，则使用者利用手指150在触控式屏幕100上的编辑视窗128作相对应的移动即可。然而，当使用者欲描绘尺寸更小的字或者图案时，由于手指150的尺寸太大，因此使用者几乎不可能写出很小的字或者图案。Assuming that the user needs to draw a word “w” on the operation interface, the user can use thefinger 150 to move theediting window 128 on thetouch screen 100 correspondingly. However, when the user wants to draw smaller characters or patterns, it is almost impossible for the user to write small characters or patterns because the size of thefinger 150 is too large.

以点选功能为例，请参照图1b，其所示为视窗操作系统上的点选动作示意图。此视窗操作系统于触控式屏幕100上可显示多个触控图样(例如A～H八个触控图样)可供点选。由于触控图样的尺寸很小，因此使用者利用手指150进行点选时，常常不慎会点选错误。由图1b可知，使用者欲点选“F”触控图样，但是由于触控图样的尺寸太小且手指150的尺寸太大，使用者很可能点选到“B”触控图样，因而造成使用者的不便。Taking the point-and-click function as an example, please refer to FIG. 1 b , which is a schematic diagram of a point-and-click action on the Windows operating system. The windows operating system can display a plurality of touch patterns (for example, eight touch patterns A to H) on thetouch screen 100 for selection. Due to the small size of the touch pattern, when the user uses thefinger 150 to click, the user often makes a wrong click. It can be seen from FIG. 1b that the user intends to click on the “F” touch pattern, but since the size of the touch pattern is too small and the size of thefinger 150 is too large, the user may click on the “B” touch pattern, resulting in User Inconvenience.

In one embodiment, multiple application modules and driver modules are loaded in the electronic device. When the user uses two fingers (that is, a plurality of first touch points) to press on the touch screen for more than a predetermined time, it can be determined that the user intends to zoom in on a part of the area. Then, the enlarged area can be displayed on the touch screen, that is, the user will perform gesture control actions in the enlarged area. Then, when the user performs a gesture control action in the above-mentioned enlarged area, the position signal corresponding to the second touch point will perform scaling calculation (Scaling) to generate a corresponding conversion signal, and the operating system will execute according to the conversion signal. Corresponding gesture control action. In other words, according to the conversion position signal corresponding to the second touch point, an editing action, a clicking action, or a screen moving action can be performed.

请参照图2，其所示为本发明一实施例具触控式屏幕中各组件之间的动作关系示意图。其包括触控单元(touch unit)200与过滤单元(filter unit)204，于一实施例中，其中触控单元200为触控式屏幕的驱动模块(driver)，此驱动模块是根据用户于触控式屏幕上所点选的触控点，输出相对应的位置信号，而此位置信号可为坐标信号。于一实施例中，过滤单元204也是属于驱动模块，其可接收触控产生单元200所输出的位置信号，并且执行位置信号的过滤动作。当然，过滤单元204也可以利用固件来达成。Please refer to FIG. 2 , which is a schematic diagram showing the action relationship between components in the touch screen according to an embodiment of the present invention. It includes a touch unit (touch unit) 200 and a filter unit (filter unit) 204. In one embodiment, the touch unit 200 is a driver module (driver) of the touch screen. The touch point selected on the control screen outputs a corresponding position signal, and the position signal can be a coordinate signal. In one embodiment, the filtering unit 204 also belongs to the driving module, which can receive the position signal output by the touch generating unit 200 and perform filtering of the position signal. Of course, the filtering unit 204 can also be implemented by firmware.

再者于一实施例中，此架构还包括手势引擎(gesture engine)206、影像放大应用模块(image magnifier application program)208、以及控制应用模块(controlapplication program)210。其中，过滤单元204是利用应用模块接口(applicationprogram interface，简称API)来与手势引擎206以及视窗控制应用模块210来传递位置信号。于一实施例中，控制应用程序为微软公司窗口操作系统(MicrosoftWindows)中的窗口控制应用程序(windows control application program)。Furthermore, in one embodiment, the framework further includes a gesture engine (gesture engine) 206 , an image magnifier application program (image magnifier application program) 208 , and a control application program (control application program) 210 . Wherein, the filtering unit 204 uses an application program interface (API for short) to communicate position signals with the gesture engine 206 and the window control application module 210 . In one embodiment, the control application program is a window control application program (windows control application program) in Microsoft Windows.

请参照图3a，其所示为本发明具触控式屏幕的电子装置其显示控制方法流程图。此电子装置需要具备如图2所示的架构，亦即加载触控单元200、过滤单元204的驱动模块以及手势引擎206、影像放大应用模块208、以及视窗控制应用模块210。Please refer to FIG. 3 a , which is a flow chart of the display control method of the electronic device with touch screen according to the present invention. The electronic device needs to have the architecture shown in FIG. 2 , that is to load the touch unit 200 , the driver module of the filter unit 204 , the gesture engine 206 , the image zoom application module 208 , and the window control application module 210 .

首先，确认多个第一组触控点在触控式屏幕上停留超过预设时间(步骤S410)；进行部分区域图形放大动作，使得触控式屏幕显示放大区域(步骤S420)；接着，于放大区域中进行第二触控点的接触以产生对应的位置信号(步骤S430)；将位置信号进行缩放计算后产生转换信号并输入控制应用模块(步骤S440)。First, confirm that a plurality of the first group of touch points stay on the touch screen for more than a preset time (step S410); perform a partial region graphics zoom-in action, so that the touch screen displays the enlarged area (step S420); then, in Contact the second touch point in the enlarged area to generate a corresponding position signal (step S430); perform scaling calculation on the position signal to generate a conversion signal and input it into the control application module (step S440).

再者，步骤S420中可利用不同的方式来实现。如图3b所示，根据第一组触控点显示提示影像区域(步骤S421)；接着，将提示影像区域进行图形放大动作以形成放大区域(S422)。或者，如图3c所示，根据第一组触控点显示提示影像区域(步骤S423)；移动提示区域至选择区域(步骤S424)；接着，将选择区域进行图形放大动作以形成放大区域(S425)。以下的说明会详细的介绍本发明的细部动作原理。Furthermore, step S420 can be implemented in different ways. As shown in FIG. 3 b , the prompt image area is displayed according to the first group of touch points (step S421 ); then, the prompt image area is enlarged to form an enlarged area ( S422 ). Or, as shown in FIG. 3c, display the prompt image area according to the first group of touch points (step S423); move the prompt area to the selected area (step S424); then, perform a graphic zoom-in action on the selected area to form an enlarged area (S425 ). The following description will introduce the detail action principle of the present invention in detail.

根据本发明的实施例，当使用者想要描绘较小的字或者图案时，用户先利用二根手指头(第一组触控点)按压在触控式屏幕上超过预定时间后，就会判断出使用者欲进行部分区域图形放大动作。接着，使用者即可在触控式屏幕的放大区域中进行手势控制动作。而在手势控制动作进行时，所产生的第二触控点所对应的位置信号需进行缩放计算(Scaling)进而产生相对应的转换信号，而操作系统即根据此转换位置信号来执行相对应的手势控制动作。如上所示，此手势控制动作包括编辑动作、点选动作、或者画面移动动作。According to the embodiment of the present invention, when the user wants to draw a smaller word or pattern, the user first uses two fingers (the first group of touch points) to press on the touch screen for more than a predetermined time, and then It is determined that the user intends to perform an action of enlarging the graphics of a part of the region. Then, the user can perform gesture control actions in the enlarged area of the touch screen. When the gesture control action is in progress, the generated position signal corresponding to the second touch point needs to be scaled and calculated (Scaling) to generate a corresponding conversion signal, and the operating system performs the corresponding conversion according to the converted position signal. Gestures control actions. As shown above, the gesture control actions include editing actions, clicking actions, or screen moving actions.

以下利用图4a至图4c，来说明本发明运用于编辑动作的显示控制流程。其是搭配图3a与图3b的流程图来作解释。此视窗操作系统于触控式屏幕300上可显示出操作系统的工具栏310，而工具栏310上有多个用户接口，例如开始按钮312、以及网络状态图形314。而在操作系统上执行图形编辑软件320(例如小画家)，此图形编辑软件320的视窗上也有相对应的用户接口，例如结束按钮322、缩放按钮324、最小化按钮326。4a to 4c are used to illustrate the display control flow of the present invention applied to the editing operation. It is explained together with the flowcharts of FIG. 3a and FIG. 3b. The Windows operating system can display atoolbar 310 of the operating system on thetouch screen 300 , and there are multiple user interfaces on thetoolbar 310 , such as astart button 312 and a network status graphic 314 . And execute graphic editing software 320 (such as little painter) on the operating system, there is also corresponding user interface on the window of thisgraphic editing software 320, forexample end button 322,zoom button 324, minimizebutton 326.

假设使用者欲在屏幕上描绘小字体的“w”。首先，使用者必须将二个手指350、355接触于触控式屏幕300上的编辑视窗328中。此时，触控单元200会将二手指350、355相对应的位置信号传递至过滤单元204、手势引擎206。Assume that the user wants to draw a small font "w" on the screen. First, the user has to touch twofingers 350 , 355 in theedit window 328 on thetouch screen 300 . At this time, the touch unit 200 transmits the position signals corresponding to the twofingers 350 and 355 to the filter unit 204 and the gesture engine 206 .

其中，手势引擎206主要的功能是在判断用户是否利用二根手指350、355来得知使用者欲进行本发明的部分区域图形放大动作。请参照图4a，根据本发明的实施例，当使用者利用二根手指头350、355(二个触控点)按压在触控式屏幕300上超过预定时间，手势引擎206会判断出用户欲进行图形放大动作。也就是说，手势引擎206会持续判断上述二位置信号是否有改变，如果二位置信号经过预定时间，例如0.5秒皆未改变，则手势引擎206确认用户欲进行图形放大动作。此时，此二位置信号会进一步传递至影像放大应用程序208。Among them, the main function of the gesture engine 206 is to determine whether the user uses the twofingers 350, 355 to know that the user intends to perform the zoom-in action of the partial area graphics of the present invention. Please refer to FIG. 4a, according to an embodiment of the present invention, when the user uses twofingers 350, 355 (two touch points) to press on thetouch screen 300 for more than a predetermined time, the gesture engine 206 will determine that the user wants to Perform graphics zoom-in action. That is to say, the gesture engine 206 will continue to judge whether the two position signals have changed. If the two position signals have not changed for a predetermined time, for example, 0.5 seconds, the gesture engine 206 will confirm that the user intends to zoom in on the graphic. At this time, the two position signals are further transmitted to the image enlargement application program 208 .

当影像放大应用程序208，接收到二位置信号后，会在上述二位置信号所定义的范围中呈现提示影像区域332。换句话说，当使用者将二手指头350、355接触于触控式屏幕300上超过预定时间之后，可于触控式屏幕300上看到提示影像区域332的出现。其中，上述提示影像区域332可以是一个反白的影像、或者是闪烁的影像。When the image enlargement application 208 receives the two position signals, it will present theprompt image area 332 within the range defined by the above two position signals. In other words, when the user touches the twofingers 350 , 355 on thetouch screen 300 for more than a predetermined time, theprompt image area 332 can be seen on thetouch screen 300 . Wherein, theprompt image area 332 may be a highlighted image or a flickering image.

接着，而如图4b所示，当使用者将二手指350、355移动离开触控式屏幕300，触控式屏幕300上会出现放大区域336。也就是说，当使用者的手指350、355离开触控面板300时，影像放大应用模块208会将提示影像区域332进行图形放大动作并转换为放大区域336。此时，放大的几何形状区域336的坐标范围也会传递至手势引擎206以及过滤单元204。Then, as shown in FIG. 4 b , when the user moves the twofingers 350 , 355 away from thetouch screen 300 , anenlarged area 336 will appear on thetouch screen 300 . That is to say, when the user'sfingers 350 , 355 leave thetouch panel 300 , the image magnification application module 208 will prompt theimage area 332 to perform a graphic magnification action and convert it into themagnification area 336 . At this time, the coordinate range of the enlargedgeometric shape area 336 is also transmitted to the gesture engine 206 and the filtering unit 204 .

如图4c所示，当用户在放大区域336上进行编辑与描绘时，触控单元200即将手指350所对应产生的位置信号传递至影像放大应用模块208以显示用户所描绘的图案。As shown in FIG. 4 c , when the user edits and draws on the zoom-inarea 336 , the touch unit 200 transmits the position signal corresponding to thefinger 350 to the image zoom-in application module 208 to display the pattern drawn by the user.

同时，过滤单元204也会将位置信号进行缩放计算(scaling)并产生转换信号后输入控制应用模块210。也就是说，虽然使用者可在放大的几何图形区域336上看到并编辑与描绘图案，但是实际上这些描绘的图案是要显示在提示影像区域332之内。因此，过滤单元204会将位于放大区域336中所有的位置信号皆改变为转换信号后，再输入至控制应用模块210。此时，视窗控制应用程序210会根据转换信号进而在触控式屏幕300上的提示影像区域332呈现较小编辑图案。At the same time, the filtering unit 204 also performs scaling calculation (scaling) on the position signal to generate a converted signal and input it to the control application module 210 . That is to say, although the user can see, edit and draw patterns on the enlargedgeometric figure area 336 , actually these drawn patterns are to be displayed in theprompt image area 332 . Therefore, the filter unit 204 changes all the position signals in theamplification area 336 into converted signals, and then inputs them to the control application module 210 . At this time, the window control application 210 will present a small editing pattern in theprompt image area 332 on thetouch screen 300 according to the conversion signal.

换句话说，虽然用户是在放大区域336进行编辑与描绘，而相对应的位置信号也不是在提示影像区域332中，但是本发明的过滤单元204可利用缩放计算来将位置信号转变为转换信号，而转换信号皆位于提示影像区域332之内，因此控制应用模块210即可以产生较小的描绘图案。In other words, although the user is editing and drawing in theenlarged area 336, and the corresponding position signal is not in theprompt image area 332, the filter unit 204 of the present invention can convert the position signal into a conversion signal by using zoom calculation , and the conversion signals are located within theprompt image area 332 , so the control application module 210 can generate a smaller drawing pattern.

接着，以下利用图5a至图5f，来说明本发明运用于点选动作以及画面移动动作的显示控制流程。其是搭配图3a与图3c的流程图来作解释。此视窗操作系统于触控式屏幕300上显示出多个触控图样(例如A～H八个触控图样)可供点选。Next, the display control flow of the present invention applied to the click action and the screen movement action will be described below using FIG. 5a to FIG. 5f. It is explained together with the flowcharts of FIG. 3a and FIG. 3c. The windows operating system displays a plurality of touch patterns (for example, eight touch patterns A to H) on thetouch screen 300 for selection.

假设使用者欲点选其中一个触控图样。首先，使用者必须将二个手指350、355接触于触控式屏幕300上。此时，触控单元200会将二手指350、355相对应的位置信号传递至过滤单元204、手势引擎206。Assume that the user wants to click one of the touch patterns. First, the user must touch the twofingers 350 , 355 on thetouch screen 300 . At this time, the touch unit 200 transmits the position signals corresponding to the twofingers 350 and 355 to the filter unit 204 and the gesture engine 206 .

其中，手势引擎206主要的功能是在判断用户是否利用二根手指350、355来进行本发明的部分区域图形放大动作。请参照图5a，根据本发明的实施例，当使用者利用二根手指头350、355(第一组触控点)按压在触控式屏幕300上超过预定时间，手势引擎206会判断出用户欲进行部分区域图形放大动作。也就是说，手势引擎206会持续判断上述二位置信号是否有改变，如果二位置信号经过预定时间，例如0.5秒皆未改变，则手势引擎206确认用户欲进行部分区域图形放大动作。此时，此二位置信号会进一步传递至影像放大应用程序208。Among them, the main function of the gesture engine 206 is to judge whether the user uses twofingers 350, 355 to perform the zoom-in action of the partial area graphics of the present invention. Please refer to FIG. 5a, according to an embodiment of the present invention, when the user uses twofingers 350, 355 (the first group of touch points) to press on thetouch screen 300 for more than a predetermined time, the gesture engine 206 will determine that the user It is desired to zoom in on part of the area graphics. That is to say, the gesture engine 206 will continue to determine whether the above two position signals have changed. If the two position signals have not changed for a predetermined time, such as 0.5 seconds, the gesture engine 206 will confirm that the user intends to zoom in on the partial area graphics. At this time, the two position signals are further transmitted to the image enlargement application program 208 .

当影像放大应用程序208，接收到二位置信号后，会在上述二位置信号所定义的范围中呈现提示影像区域332。换句话说，当使用者将二手指头350、355接触于触控式屏幕300上超过预定时间之后，可于触控式屏幕300上看到提示影像区域332的出现，用以通知使用者可进一步的动作。其中，上述提示影像区域332可以是一个反白的影像、或者是闪烁的影像。When the image enlargement application 208 receives the two position signals, it will present theprompt image area 332 within the range defined by the above two position signals. In other words, when the user touches the twofingers 350, 355 on thetouch screen 300 for more than a predetermined time, theprompt image area 332 can be seen on thetouch screen 300 to inform the user that further steps can be taken. Actions. Wherein, theprompt image area 332 may be a highlighted image or a flickering image.

接着，当提示影像区域332出现时，用户可移动二手指350、355至欲进行手势控制动作的区域。亦即，触控单元200会持续地将二个位置信号传递至手势引擎206以及影像放大应用模块208。而影像放大应用程序208会根据二个位置信号而持续改变提示影像332的尺寸以及位置。而如图5b所示，最终使用者选定选择区域334后，即可将二手指350、355移动离开触控式屏幕300。Then, when theprompt image area 332 appears, the user can move the twofingers 350, 355 to the area where the gesture control action is to be performed. That is, the touch unit 200 will continuously transmit two position signals to the gesture engine 206 and the image zoom application module 208 . The image enlargement application 208 will continuously change the size and position of theprompt image 332 according to the two position signals. As shown in FIG. 5 b , after the final user selects theselection area 334 , the twofingers 350 , 355 can be moved away from thetouch screen 300 .

接着，如图5c所示，触控式屏幕300上会出现放大的几何形状区域336。也就是说，使用者可以移动二个手指350、355至任意的位置以选定选择区域334。于手指350、355离开触控面板300时，影像放大应用模块208会将选择区域334进行影图形放大动作并转换为放大区域336且显示于触控式屏幕300。此时，放大区域336的坐标范围也会传递至手势引擎206以及过滤单元204。Then, as shown in FIG. 5 c , an enlargedgeometric shape area 336 appears on thetouch screen 300 . That is to say, the user can move the twofingers 350 , 355 to any position to select theselection area 334 . When thefingers 350 and 355 leave thetouch panel 300 , the image magnification application module 208 will zoom in on the selectedarea 334 and convert it into anenlarged area 336 and display it on thetouch screen 300 . At this time, the coordinate range of theenlarged area 336 is also transmitted to the gesture engine 206 and the filtering unit 204 .

此时，如图5d所示，用户即可在放大区域336上进行点选动作。很明显地，手指350是触控于放大的“H”触控图样，而上述位置信号会被传递至影像放大应用模块208。同时，过滤单元204也会将此位置信号进行缩放计算(scaling)并产生一个转换信号后输入控制应用模块210，而上述转换信号是位于选择区域334中的“H”触控图样上。也就是说，虽然用户在放大区域336上点选放大的“H”触控图样，但是实际上过滤单元204会将位于放大的几何图形区域336中的位置信号改变为转换信号后，再输入至控制应用模块210。At this time, as shown in FIG. 5 d , the user can click on theenlarged area 336 . Obviously, thefinger 350 is touching the magnified “H” touch pattern, and the position signal will be transmitted to the image magnification application module 208 . At the same time, the filtering unit 204 also performs scaling calculation (scaling) on the position signal to generate a conversion signal and then input it into the control application module 210 , and the conversion signal is located on the “H” touch pattern in theselection area 334 . That is to say, although the user clicks the enlarged "H" touch pattern on theenlarged area 336, the filter unit 204 will actually change the position signal located in the enlargedgeometric figure area 336 into a conversion signal, and then input it to Control application module 210 .

很明显地，由于上述转换信号是位于几何形状区域334中的“H”触控图样上。因此，控制应用模块210即确定用户点选“H”触控图样。Obviously, since the above-mentioned conversion signal is located on the “H” touch pattern in thegeometry area 334 . Therefore, the control application module 210 determines that the user taps the “H” touch pattern.

当然，使用者也可以进行画面移动动作来点选其他的触控图样。如图5e所示，用户利用手指350在放大的几何图形区域336由上往下移动，并产生相对应的位置信号传递至过滤单元204、手势引擎206、与影像放大应用程序208，而影像放大应用模块208即进行画面移动动作。也就是将“C”、“G”、“B”、“F”触控图样依序显示在放大区域336中。Of course, the user can also move the screen to select other touch patterns. As shown in FIG. 5e, the user uses thefinger 350 to move from top to bottom in the enlargedgeometric figure area 336, and generates a corresponding position signal and transmits it to the filter unit 204, the gesture engine 206, and the image zoom-in application program 208, and the image zooms in. The application module 208 performs screen movement. That is, the “C”, “G”, “B” and “F” touch patterns are sequentially displayed in theenlarged area 336 .

接着，如图5f所示，用户即可在放大的几何图形区域336上进行点选动作。很明显地，手指350是触控于放大的“F”触控图样，而上述位置信号会被传递至影像放大应用程序208。同时，过滤单元204也会将此位置信号进行缩放计算(scaling)并产生一个转换信号后输入控制应用模块210，而上述转换位置信号是位于放大区域334中的“F”触控图样上。也就是说，虽然用户在放大区域336上点选放大的“F”触控图样，但是实际上过滤单元204会将位于放大区域336中的位置信号改变为转换信号后，再输入至控制应用模块210。Then, as shown in FIG. 5 f , the user can click on the enlargedgeometric figure area 336 . Obviously, thefinger 350 is touching the magnified “F” touch pattern, and the position signal will be transmitted to the image magnification application 208 . At the same time, the filtering unit 204 also performs scaling calculation (scaling) on the position signal to generate a converted signal and then input it into the control application module 210 , and the converted position signal is located on the “F” touch pattern in theenlarged area 334 . That is to say, although the user clicks the enlarged "F" touch pattern on theenlarged area 336, the filter unit 204 will actually change the position signal located in theenlarged area 336 into a converted signal, and then input it to the control application module 210.

很明显地，由于上述转换信号是位于几何形状区域334中的“F”触控图样上。因此，控制应用模块210即确定用户点选“F”触控图样。Obviously, since the above-mentioned conversion signal is located on the “F” touch pattern in thegeometry area 334 . Therefore, the control application module 210 determines that the user taps the “F” touch pattern.

本发明的优点是于具有触控式屏幕的电子装置中加载多个应用程序以及驱动模块。此电子装置可为桌上型电脑系统、可携式平板电脑、或者是笔记本电脑等等。当使用者选定提示影像区域或者选择区域进行编辑与描绘时，会先在触控式屏幕上显示放大区域来让用户进行编辑与描绘。当用户在放大区域中操作时，相对应的位置信号会进行缩放计算，并且成为转换信号输入视窗控制应用程序。因此，操作系统即根据转换信号将进行用户所欲进行的手势控制动作。如此，可以解决习知手指触控面积太大造成电子装置误操作的情形发生。The advantage of the present invention is to load multiple application programs and driver modules in the electronic device with touch screen. The electronic device can be a desktop computer system, a portable tablet computer, or a notebook computer and so on. When the user selects a prompt image area or selects an area for editing and drawing, the enlarged area will first be displayed on the touch screen to allow the user to edit and draw. When the user operates in the magnified area, the corresponding position signal is subjected to zoom calculations and becomes the transformation signal input to the window control application. Therefore, the operating system will perform the gesture control action desired by the user according to the conversion signal. In this way, it is possible to solve the conventional situation that the electronic device is misoperated due to the large touch area of the finger.
