For users, a larger screen can not only provide better visual enjoyment, but also feel more convenient when operating, and the thinner and lighter products also bring convenience to users.

When a touch screen is used as an input interface, a mechanism must be developed to judge the user's actions and react. Among them, the soft keyboard (SoftwareInputPanel, SIP) is a technology developed for inputting text through the touch screen. The difference from traditional hardware buttons is that when a user operates a hardware button, the consumer electronic product can determine the pressed button according to the signal generated by the button. However, for consumer electronic products using a soft keyboard as an input interface, an additional method must be designed to determine which button on the soft keyboard the button clicked by the user is. Generally speaking, after the user touches the soft keyboard with his finger, the soft keyboard application program will compare the areas covered by the fingers of each key, and use the key covered by the finger the most as the key selected by the user. According to the use experience and investigation results, the selected button is not the position that the user wants to press when operating the touch screen.

Detailed ways

In order to make the content of the present invention more clear, the following specific examples are given as examples in which the present invention can indeed be implemented.

FIG. 1 is a block diagram of an electronic device according to an embodiment of the invention. Referring to FIG. 1 , the electronic device 100 includes a touch screen 110 , a representative coordinate value determining module 120 , and a processing module 130 . In this embodiment, the electronic device 100 may be a personal digital assistant (PDA) mobile phone, a smart phone (Smartphone), a touch phone (Touchphone), or a mobile computer (Mobilecomputer), etc., and the scope thereof is not limited here.

Wherein, the touch screen 110 is, for example, a resistive touch screen. In addition to being used as a display interface of the electronic device 100, it can also detect when a user touches the touch screen 110 with an input tool (such as a finger or a stylus). Each contact area is formed, and all contact pressure points covered by each contact area are obtained.

The representative coordinate value determination module 120 is connected to the touch screen 110 for determining representative coordinate values according to the coordinate values of each touch pressure point after the touch screen 110 obtains all the touch pressure points. Wherein, the representative coordinate value determination module 120 is, for example, a controller (Controller), or a chip (Chip) separately configured inside the electronic device 100 . It should be noted here that no matter whether the touch screen 110 detects more than one contact area, the representative coordinate value determination module 120 will only determine a unique representative coordinate value.

The processing module 130 is connected to the representative coordinate value determination module 120 , and after the representative coordinate value determination module 120 determines the representative coordinate value, it controls the application program installed in the electronic device 100 to execute the corresponding function according to the representative coordinate value.

The following embodiments will take the electronic device 100 as an example to describe the detailed steps of manipulating the application programs through the touch screen 110 . FIG. 2 is a flowchart of a method for controlling an application program according to an embodiment of the invention. Please refer to FIG. 1 and FIG. 2 at the same time. When the user is ready to operate the electronic device 100 , he can use an input tool such as a finger or a touch pen to touch the touch screen 110 . Since the input tool itself has a certain width, as shown in step 210 , the touch screen 110 detects the contact area generated by the contact with the input tool after the input tool is in contact with it. Wherein, the touch screen 110 can simultaneously detect one or more contact areas. Then in step 220 , the touch screen 110 obtains each touch pressure point covered by each contact area.

Next, as shown in step 230 , the representative coordinate value determination module 120 determines a representative coordinate value according to the coordinate values of all touch points. In one embodiment, the coordinate value of each pressure point includes two components, the x-axis coordinate value and the y-axis coordinate value, and the following is how the representative coordinate value determination module 120 determines the Computes detailed instructions for representing coordinate values. After the touch screen 110 obtains the touch pressure points covered by each contact area, the representative coordinate value determination module 120 obtains the x-axis coordinate value of each touch pressure point, and calculates the average of the above-mentioned x-axis coordinate values (hereinafter referred to as x-axis coordinate mean). Similarly, the representative coordinate value determination module 120 also obtains the y-axis coordinate values of all touch points, and calculates the average thereof to obtain a y-axis coordinate average value. After the calculation is completed, the representative coordinate value determining module 120 uses the average value of the x-axis coordinates and the average value of the y-axis coordinates as the representative coordinate values representing all the touch points.

In another embodiment, the representative coordinate value determining module 120 firstly defines respective weight values for each x-axis coordinate value and y-axis coordinate value. Wherein, the method of defining the weight value includes obtaining the pressure value of each touch point (the pressure value is related to the force with which the user touches the touch screen 110), and defining the x-axis of each touch point with the corresponding pressure value The weight value of the coordinate value and the y-axis coordinate value. For example, a higher pressure value is given a higher weight value. In addition, the representative coordinate value determination module 120 can also define the weight value according to the user's past experience. Next, the representative coordinate value determination module 120 calculates the weighted average value of the x-axis coordinates with each x-axis coordinate value and the corresponding weight value (for example, calculates the product of each x-axis coordinate value and the corresponding weight value, and then calculates the above product ), and calculate the weighted average value of the y-axis coordinates with each y-axis coordinate value and the corresponding weight value (for example, calculate the product of each y-axis coordinate value and the corresponding weight value separately, and then calculate the average value of the above products ). Finally, the weighted average value of the x-axis coordinates and the weighted average value of the y-axis coordinates are used as the representative coordinate values of all touch pressure points.

As mentioned above, it can be found that the representative coordinate value calculated by the representative coordinate value determination module 120 is a unique and absolute coordinate value. However, it must be noted that the method of calculating the average value of the x-axis coordinates and the average value of the y-axis coordinates includes calculating the average according to the number of touch pressure points, or calculating the weighted average based on empirical values, which is not used here. There is no restriction on the manner in which the average is calculated.

Finally, as shown in step 240 , the processing module 130 controls the application program in the electronic device 100 to execute the corresponding function according to the representative coordinate value, thereby completing the process of manipulating the application program through the touch screen 110 . It must be noted that the processing module 130 can control any application program executed on the electronic device 100 to perform functions according to the representative coordinate values, and the type of the application program is not intended to limit the scope of the present invention.

In the above embodiments, the touch points detected by the touch screen 110 correspond to the user's operation actions, and the representative coordinate values calculated by the representative coordinate value determination module 120 are used to represent these touch points. Therefore, the user's operations on the touch screen 110 can be represented by representative coordinate values. Accordingly, after the processing module 130 transmits the representative coordinate value to the application program, the function executed by the application program according to the representative coordinate value is to reflect the user's operation action.

It is worth mentioning that, in another embodiment, the electronic device 100 only includes the touch screen 110 and the processing module 130 connected to each other. Wherein, in addition to the functions disclosed in the above-mentioned embodiments, the processing module 130 can also perform various actions that can be performed by the representative coordinate value determining module 120 in the above-mentioned embodiments. Therefore, in this embodiment, only the processing module 130 can determine the representative coordinate values used to represent all touch pressure points, and no additional controller or chip is needed to realize the function of the representative coordinate value determination module 120 .

There are many kinds of application programs executed on the electronic device 100 , and the following will take the soft keyboard application program as an example to further illustrate the detailed steps of the processing module 130 controlling the application program to perform functions according to the representative coordinate values. Wherein, the soft keyboard application program is used to display a soft keyboard including several keys on the touch screen 110 .

After the processing module 130 receives the representative coordinate value sent by the representative coordinate value determining module 120, it will send the representative coordinate value to the soft keyboard application program. The soft keyboard application program will determine a click button from all the buttons on the soft keyboard according to the received representative coordinate value.

FIG. 3 is a schematic diagram of a touch screen according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 3 at the same time. The soft keyboard application system draws a soft keyboard comprising several keys on the touch screen 110 according to the size of the touch screen 110 and the predefined keyboard display area (such as the soft keyboard shown in FIG. 3 ). keyboard 310), and draw several buttons according to the type of the soft keyboard 310 and the preset value of the button size. Accordingly, after the soft keyboard application program receives the representative coordinate value, it first calculates the key display area of each key on the touch screen 110 according to the key display area and the preset value of the key size of each key. Then, find out the button display area that can cover the representative coordinate value from the button display area of each button, and use the button corresponding to this button display area as the click button. For the convenience of description, it is assumed that the key display area corresponding to the key 320 covers the representative coordinate value transmitted from the processing module 130 , so the key 320 will be regarded as a click key by the soft keyboard application.

In one embodiment, after the soft keyboard application program determines to click on a button (such as the button 320 ), the clickable button will be enlarged and displayed on the touch screen 110 . For example, the soft keyboard application will scale up the clicked key, and the result of scaling up the clicked key is shown as the key 320 in FIG. 4A .

In another embodiment, as shown in FIG. 4B , after deciding to click the button (ie, the button 320 ), the soft keyboard application will display an image 330 on another area (eg, the upper area) of the touch screen 110 . Wherein, the appearance of the image 330 is the same as that of the click button 320 .

In yet another embodiment, the image displayed by the soft keyboard application includes input prompt information. The input prompt information, for example, will display characters corresponding to the clicked buttons in turn, and the corresponding characters of the clicked buttons will be related to the input mode currently set by the electronic device 100 . Through the input prompt information on the image, the user can know the character to be input after releasing the click button.

As mentioned above, the soft keyboard application program judges the button clicked by the user according to the representative coordinate value, and through various visual feedback (visual feedback) effects (such as zooming in on the clicked button, or displaying images in other areas) allows the user to It is easy to judge whether the input tool is pressed to the correct position. On the other hand, the visual feedback can also allow the user to preview the characters to be input, so as to avoid operating errors and reduce the efficiency of using the electronic device 100 .

According to experience and investigation results, the only representative coordinate value obtained after calculating the coordinate value of the touch point is often the position that the user most wants to press when operating the touch screen. Therefore as shown in FIG. 5, when the soft keyboard 520 is displayed on the touch screen 500, it is assumed that in the contact area 510 generated by the user touching the touch screen 500, 11 touch pressure points (in FIG. represented by the "·" symbol), and the representative coordinate values obtained according to the coordinate values of these touch points (its position is shown by the "*" symbol), which correspond to the key that the user most wants to press (that is, Covers the key 521 area representing the coordinate value). In this embodiment, the button 521 will present a visual feedback effect such as zooming in on the spot, so as to further help the user confirm whether the pressed button is the button that the user wants to select. In another embodiment, an image with the same appearance as the key 521 will be displayed on other areas (eg, the upper area) of the touch screen 500 , so that it is easier for the user to confirm whether the correct key is pressed.

The above-mentioned embodiments can be applied to any electronic device operated through a touch screen. However, since most resistive touch screens support single-touch technology, the present invention is especially applicable to electronic devices configured with a resistive touch screen. According to the characteristics of the resistive touch screen itself, the present invention can respond to the user's operation action most simply, quickly and accurately, so as to provide the best operation effect.

To sum up, the method for manipulating an application program, its electronic device, storage medium, and computer program product using the method described in the present invention obtain the contact area generated by the contact between the input tool and the touch screen, and then touch the touch screen. The coordinate values of each touch point covered by the area are averaged to obtain a unique representative coordinate value. Since the representative coordinate value can be used to represent the user's operation action, when the control application program executes the corresponding function according to the representative coordinate value, it can properly respond to the user's operation. Through the above method, not only can the application program be controlled simply and accurately, but also the convenience for the user to operate the electronic device by using the touch screen can be improved.

Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention.
