Referring to FIG. 1 and FIG. 2 , in step S210 of FIG. 2 , the touch device 120 senses whether a contact area is currently generated on the touch device 120 . That is, the touch device 120 senses whether the user's finger currently touches the touch device 120 in step S210. If no, it means that the user does not touch the touch device 120 at present, that is, the user does not currently intend to perform the operation of the page. If the contact area is generated on the touch device 120, the process proceeds from step S210 to step S220, and the touch device 120 continuously detects whether the contact area change occurs. In some embodiments, the step S210 can be omitted, that is, the touch device 120 can directly detect whether the contact area is generated on the touch device 120, and directly detect whether the contact area is generated on the touch device 120. Variety.

When the touch device 120 detects a change in the contact area, the touch device 120 transmits the contact area change sensing data to the processing unit 110. The computing module 112 in the processing unit 110 then calculates the contact area change sensing data to obtain the value of the contact area change and the center of gravity displacement vector. The calculation of the contact area change value and its center of gravity displacement vector will be described in detail later with reference to FIGS. 3A and 3B.

The computing module 112 compares the calculated contact area change value with a preset threshold value. Referring to step S230 of FIG. 2, the operation module 112 determines whether the value of the contact area change is less than or equal to a preset threshold value. If the value is less than or equal to the preset threshold, step S240 is performed, and the operation module 112 instructs the display module 114 to move the display page on the electronic device 100 according to the predetermined speed, and the direction of the displacement of the center of gravity according to the change of the contact area Decide. If the value of the change of the contact area is greater than the preset threshold, step S250 is performed, and the operation module 112 instructs the display module 114 to move the display page on the electronic device 100 according to the predetermined acceleration, and the center of gravity displacement vector according to the contact area changes according to the contact area. The direction is determined. Finally, the display module 114 displays the page operation on the display device 130.

3A and 3B are schematic diagrams showing changes in contact area and center of gravity displacement vectors on the touch device, respectively. For convenience of the following description, each sensing unit on the touch device 102 is labeled to be illustrated as a grid array of FIGS. 3A-3B. FIG. 3A is used to illustrate the change in contact area on the touch device 120. In the touch device 120, the contact area may be different due to the different force exerted by the finger 300 on the touch device. change. For example, as shown in FIG. 3A, the left diagram of FIG. 3A is an example in which the finger 300 gently touches the touch device 120, and the contact area CA1 is small, and the area is only 4 squares. However, if the finger touches the touch device 120 hard, as shown in the right diagram of FIG. 3A, the contact area CA2 with the touch device 120 is larger, and the area is increased to 24 squares.

The algorithm for changing the contact area is: assuming that the change in the contact area is ΔA, the contact area detected at the previous time point is A ₁ , and the currently detected contact area is A ₂ , and the contact area is changed. The value ΔA = A _{2 -} A ₁ . Taking FIG. 3A as an example, it is assumed that the contact area A ₁ detected at the last time point is 4 squares as shown in the left diagram of FIG. 3A, and the currently detected contact area A _{2 is} as shown in the right diagram of FIG. 3A. Shown are 24 squares. The algorithm for changing the contact area is A ₂ -A ₁ , that is, 24-4, and the value ΔA of the change in contact area is 20. In the embodiment of the present invention, based on the value of the change in the contact area, a corresponding page operation is taken to move the display page.

Fig. 3B is a schematic diagram of the center of gravity displacement vector of the contact area change, and two figures of the same contact area as Fig. 3A are taken as an example. The calculation method for the center of gravity O(X _o , Y _o ) of the contact area defining the area of n grid points is as shown in the following equation (1):

Where X _o is the x coordinate of the center of gravity of the contact area, and Y _o is the y coordinate of the center of gravity. X _o1 ~X _on are the x coordinates of the center points of the n grid points in the contact area, respectively, and Y _o1 ~Y _on are the y coordinates of the center points of the n grid points in the contact area, respectively. Taking the left diagram of FIG. 3B as an example, the contact area CA1 of an area of 4 (ie, n=4) grid points, the center points of each square are in order from left to right and top to bottom, respectively ( X _o1 , Y _o1 ), (X _o2 , Y _o2 ), (X _o3 , Y _o4 ), (X _o4 , Y _o4 ). Substituting equation (1), the center of gravity coordinate O(X _o , Y _o ) of the contact area CA1 is obtained.

Similarly, the contact area CA2 of the area of 24 grid points (ie, n=24) in the right diagram of FIG. 3B, the center of gravity coordinate M(X _m , Y _m ) is

Referring to the right diagram of FIG. 3B, the point O is the center of gravity of the contact area CA1 before the contact area changes. The center of gravity of the contact area CA2 after the contact area change is located at the point M. Define its center of gravity displacement vector for ,which is, . The OM line with the arrow indicating the direction on the right image of Fig. 3B indicates the center of gravity displacement vector. In the embodiment of the invention, the direction of the page movement is determined by the direction of the center of gravity displacement vector.

4A and FIG. 4B are schematic diagrams of a page operation and a page operation, respectively, according to an embodiment of the invention. Referring to FIGS. 1 and 4 , in this embodiment, the touch device 120 and the display device 130 of the electronic device 100 are integrated into the touch panel 400 . The display screen of the touch panel 400 includes a display page 410, a display page 420, and a plurality of prompt icons in the lower right corner, for example, a time prompt 460 and a power indicator 470. In addition, the display page 420 includes three application icons: a graphic 421, a graphic 422, and a graphic 423.

When the user's finger 450 touches the touch panel 400, the touch panel 400 defines a block that is actually in contact with the finger 450 as a contact area 440 for detecting a change in the contact area. The contact area 440 moves along with the position of the user's finger 450 on the touch panel 400. Therefore, the user can be in the touch panel 400 The page is manipulated by any change in contact area over any block in the sensing range. In some embodiments, the touch panel 400 defines a fixed area within its sensing range as the contact area 440 that does not move with the user's finger 450.

In this embodiment, the electronic device 100 can determine the position and range of the touch area 440, and the touch panel 400 can only detect the change of the contact area in the contact area 440. The change in contact area occurring in portions other than the contact area 440 does not trigger the page operation method of the embodiment of the present invention. In this embodiment, the touch panel 400 displays the contact area 440 on the display screen with a double-decked interface prompt. The interface prompt is used to indicate the location of the user's current contact area 440, the type of which is not limited to a double circle. In another embodiment, the touch panel 400 does not display the contact area 440 on the display screen with an interface prompt. In some embodiments, the contact area 440 can also be displayed or disappeared by using a specific combination of keys of the electronic device, thereby enabling or disabling the page operation function.

Referring to FIG. 2-4, when the touch panel 400 senses that the current contact area is not equal to zero, the touch panel 400 defines the block that the current finger 450 contacts as the contact area 440, and continuously detects whether the contact area 440 is in the contact area 440. There is a change in contact area. For example, the contact area of the finger 450 on the contact area 440 at the last time point is as shown in the left diagram of FIG. 3A, and the contact area of the finger 450 on the contact area 440 at the current time point is as shown in the right diagram of FIG. 3A. Shown. The contact area is increased from 4 grid points to 24 grid points. The touch panel 400 determines that the contact area changes, and the contact area change value is 20, and the center-of-gravity displacement vector before and after the change is as shown in the right diagram of FIG. 3B. Shown. The interval between the time points may be 1 second, but the present invention is not limited thereto. The value of the contact area change and the calculation method of the center of gravity displacement vector have been explained in detail above, and will not be described again here.

Assuming that the preset threshold value is 20, the value 20 of the contact area change is equal to the threshold value. Therefore, the electronic device 100 instructs the touch panel 400 according to the preset speed and the center of gravity displacement vector. The direction moves the display page 410 and the display page 420. The display screen after the page is moved is as shown in FIG. 4B. Since the movable direction of the display page 410 and the display page 420 in this embodiment is limited to the left and right, although the center of gravity displacement vector The direction of the display points to the lower right, and the actual moving direction of the display page 410 and the display page 420 is still to the right. After the page is moved, three application icons belonging to the display page 410 that are not previously displayed on the display screen can be seen on the touch panel 400: the icon 411, the icon 412, and the icon 413. The icon 422 and the icon 423 originally displayed on the touch panel 400 belonging to the display page 420 are hidden in the display screen of the touch panel 400.

The page operation method provided by the embodiment of the present invention can be automatically activated when the electronic device 100 is turned on, and the user can be manually disabled. In another embodiment consistent with the present invention, the page operation method is on the electronic device. Some applications in 100 (for example, a browser) are automatically launched when they are turned on, and can be manually closed by the user. In still another embodiment of the present invention, the page manipulation method can be manually activated and deactivated by a user. In addition, when the page operation method of the embodiment of the present invention is started, a prompt icon appears on the display screen to inform the user of the current status. For example, as shown in FIG. 4, a star icon 430 is displayed in the lower right corner of the display screen of the touch panel 400 to prompt the user to change according to the contact area. The function of the page operation is started. The appearance position and graphics of the prompt icon are not limited to the lower right corner or the star shape, and the embodiment of the invention may adjust the position of the appearance and the graphic of the prompt icon 430 according to the requirements thereof.

FIG. 5 is a flow chart of a page operation method for providing other operation options according to an embodiment of the invention. FIG. 6A and FIG. 6B are schematic diagrams of providing other operation options and providing other operation options, respectively, according to an embodiment of the invention. Referring to FIG. 6 , the display screen of the touch panel 600 includes a display page 610 , a prompt icon 430 prompting the start of the operation method, a time prompt 460 , and a power prompt 470 . The display page 610 includes three application icons: a graphic 611, a graphic 612, and a graphic 613.

5 is different from the page operation method provided in FIG. 1 in the step of detecting the contact area change in step S220 of FIG. 5 and determining whether the value of the contact area change is less than or equal to a preset threshold value. Between S230, there are more judgments as to whether other operations of the electronic device 100 are triggered at the same time, and subsequent steps thereof.

When the page operation method of the embodiment of the present invention is executed on the electronic device 100, the change of the contact area for operating the page may trigger the triggering condition of other operations of the electronic device 100 at the same time. For example, if the contact area overlaps with some display items (for example, an application icon, a webpage image, or a webpage hyperlink), the contact area change may trigger the operation of the other electronic device 100 at the same time, for example, App, click on an image or open a hyperlink.

Referring to FIG. 1 , FIG. 5 and FIG. 6 , in the embodiment, when the touch panel 600 is used When it is detected that the contact area change is generated (step S220), the processing unit 110 determines whether or not other operations are simultaneously triggered (step S510). If the processing unit 110 determines that no other operations are triggered at the same time, step S230 is performed. If the processing unit 110 determines that other operations are triggered at the same time, then step S520 is performed to display one or more options on the display device 130 for selecting an operation of the electronic device, including moving the page.

Specifically, as shown in FIG. 6A, when the contact area 630 of the user's finger 620 on the touch panel 600 is located on the application icon 613, and the change of the contact area occurs, the electronic device 100 is triggered at this time. There are at least two operations: moving the display page or opening the application represented by icon 613. Therefore, as shown in FIG. 6B, an operation option window 640 is displayed on the display screen of the touch panel 600. The operation option window 640 includes an operation option 641 for opening the application and an operation option 642 for moving the page for the user to select the operation of the electronic device 100 to be performed. In this embodiment, the operation option window 640 is adjacent to the contact area 630, which is convenient for the user to click, but the position of the appearance is not limited thereto, and the embodiment of the invention can adjust the position of the appearance according to the needs thereof.

After the user makes a selection, step S530 is performed, and the processing unit 110 determines whether the operation to be performed is a page move. If the page is moved, the process proceeds to step S230, and the processing unit determines whether the value of the contact area change is less than or equal to the preset threshold. The remaining steps are the same as those of the same number in FIG. 2, and details are not described herein again. If the page is not moved, the operation method of the page is ended, and the selected electronic device 100 is operated.

In another embodiment, when the page manipulation method of the present invention is activated, The operation of the electronic device 100 that may be triggered at the same time is closed, so that there is no problem of operating the two or more electronic devices 100 at the same time.

In summary, the present invention detects a change in the contact area on the touch device of the electronic device, and moves the display page according to the value of the contact area change and the direction of the center of gravity displacement vector. During the operation of the page, the user only needs to make different finger touches in a small range on the touch device. Therefore, the present invention allows the user to achieve the effect of quickly moving the displayed page without requiring a large finger movement.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
