Background technique

Scroll bars are widely used in a large number of data display scenes. Generally, scroll bars based on ordinary touch screens support both touch and drag operations. When tapping a position in the scroll bar area, the scroll bar calculates its X coordinate offset by the horizontal scroll bar, and the vertical scroll bar calculates the Y coordinate offset of the touch; then the calculated offset value is The maximum value of the scroll bar is compared to obtain the scroll percentage, and then the control terminal display interface jumps to the corresponding percentage position to display the corresponding data. Dragging the scroll bar takes advantage of the superimposed effect of the high-frequency automatic repeat tap operation. The terminal acquires points on the touch track path at a fixed high frequency and applies a tap operation for each point.

A disadvantage of the solution in the related art is that the scroll bar operation is based on a fixed scale enlargement operation effect. If there is large-scale data, or the list to be displayed, the length of the page is particularly long, the zoom effect of the scroll bar will be particularly obvious; reflected on the user interface, a slight click or drag operation on the scroll bar will cause the page to be Long-distance scrolling results in inaccurate positioning.

Preferred embodiment of the invention

Embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the various manners in the embodiments may be combined with each other without conflict.

The touch screen control method of the embodiment of the invention, combined with the pressure information to control the scrolling operation of the display interface, can realize flexible control of the touch screen scrolling mode, facilitates the use of the user, and enhances the user experience.

As shown in FIG. 1 , a method for controlling a touch screen according to an embodiment of the present invention includes:

Step 101: When detecting that the user performs a touch operation on an area where the information is scrolled in the display interface of the touch screen, the position information and the pressure information of the touch point are acquired.

The control method of the embodiment of the present invention may be applied to a terminal, where the terminal may include a touch screen display device that can detect a touch pressure and a touch position, and the display area of the touch screen may include a software interface area that can display valid data information and is set to control information scrolling. Software interface area.

In this step, the obtained position information and pressure information can be converted into digital signals for further processing of subsequent steps.

Step 102: Determine, according to the pressure information, an operation type corresponding to the touch operation.

In this step, the touch pressure corresponding to different strengths may be set with different operation types, such as light touch, pressing, etc., according to the detected pressure information, the operation type corresponding to the touch operation may be accurately determined.

Step 103: Control a display interface of the touch screen to perform a corresponding action according to the operation type and the location information corresponding to the touch operation.

In this step, according to the operation type and position information corresponding to the touch operation, the display interface of the touch screen can be controlled to perform corresponding actions, such as scrolling at a fixed speed or controlled scrolling in a certain direction, thereby implementing flexible control of the touch screen.

The control method of the touch screen according to the embodiment of the invention, combined with the pressure information to control the scrolling action of the display interface, can realize flexible control of the scrolling mode of the touch screen, improve the positioning accuracy, and fully satisfy the user's intention, which is convenient for the user to use and enhances. user experience. The scroll bar operation in the related art is solved based on the effect of the fixed scale enlargement operation, which may result in inaccurate positioning, and the user sliding speed is too fast or the offset track is large, which may cause the scroll bar to fail to reflect the update in time, and does not meet the user's intention. problem.

Optionally, the foregoing step 102 may include:

Step 1021: Determine whether the pressure value of the pressure information is less than a preset first pressure threshold. When the pressure value of the pressure information is less than the first pressure threshold, determine that the touch operation is a tap operation.

In this step, by comparing the pressure value of the touch operation performed by the user with the preset first pressure threshold, it can be determined whether the touch operation of the user is a light touch. For convenience of description, the first pressure threshold may be marked as P1. If the pressure value of the touch operation by the user is less than P1, the pressure of the user's touch operation is small, and the touch may be determined as a light touch.

The first pressure threshold P1 can be set according to an empirical value.

Step 1022, determining whether the pressure value of the pressure information is greater than a preset second pressure threshold. When the pressure value of the pressure information is greater than the second pressure threshold, determining that the touch operation is a pressing operation, wherein The second pressure threshold is greater than or equal to the first pressure threshold.

In this step, by comparing the pressure value of the user's touch operation with the preset second pressure threshold, it can be determined whether the user's touch operation is a press. For convenience of description, the second pressure threshold may be marked as P2. If the pressure value of the touch operation by the user is greater than P2, the pressure of the user's touch operation is large, and the pressure may be determined as pressing.

The threshold value (second pressure threshold value P2) for performing the press determination is greater than or equal to the threshold value (first pressure threshold value P1) at which the tap determination is performed, that is, P2 ≥ P1. The second pressure threshold P2 can also be set based on empirical values.

At this time, through the preset first pressure threshold and the second pressure threshold, the operation type of the user performing the touch operation can be accurately distinguished, and the corresponding operation action is performed according to the operation type, thereby laying a foundation for realizing different operation effects.

Optionally, the foregoing step 103 may include:

Step 1031: When the touch operation is a pressing operation, the display interface of the touch screen is controlled to enter a controlled scrolling state.

Here, after the display interface of the touch screen enters the controlled scrolling state, the scrolling effect of the touch screen can be adjusted in real time by changing the touch pressure, etc., thereby fully satisfying the needs of the user.

Step 1032, after the display interface of the touch screen enters a controlled scroll state, continue to detect the location The pressure information of the touch point.

Here, after the touch screen enters the controlled scroll state, the pressure of the user performing the touch operation may change, so it may be necessary to continue to detect the pressure information of the touch point to adjust the operation effect according to the user operation in real time.

Step 1033: Determine a scrolling rate according to the currently detected pressure information, and determine a scrolling direction according to the position information.

Here, in the controlled scrolling state, the scrolling rate is determined according to the currently newly detected pressure information, real-time adjustment of the scrolling rate by the combined pressure information is realized, and combined with the position information, the touchscreen can be controlled to scroll to the designated position.

Step 1034: Control a display interface of the touch screen to perform scrolling according to the scrolling rate and the scrolling direction.

At this time, the scrolling rate is determined by the pressure information, and the scrolling direction is determined by the position information, and the display interface of the touch screen can be controlled to scroll according to the user operation, thereby realizing the real-time adjustment of the rolling effect of the touch screen, improving the practicability and convenience, and improving The user experience.

Optionally, in step 1033, the determining the scroll rate according to the currently detected pressure information may include:

Step 10331: Determine whether the pressure value of the currently detected pressure information is less than the first pressure threshold, and obtain a determination result.

In this step, after the touch screen enters the controlled scroll state, it may continue to determine whether the pressure value of the touch operation by the user is greater than the first pressure threshold P1, and adjust the scroll state of the touch screen according to the determination result.

Step 10332, when the determination result is no, determining a result of dividing the pressure value of the newly detected pressure information by a preset standard pressure value as a rate factor, and determining a product of the rate factor and a preset standard rate. For the scroll rate.

Here, if the pressure value of the newly detected pressure information is not less than the first pressure threshold P1, the scroll rate can be controlled based on the newly detected pressure information. For ease of illustration, the standard pressure value can be labeled P3 and the standard rate labeled R0. When the newly detected pressure value is greater than or equal to P1, the result of dividing the newly detected pressure value by the standard pressure value P3 may be used as the rate factor, and the rate factor is multiplied by the standard rate R0 to obtain the actual rolling rate. In this way, strong pressure can produce high rolling rates, weak Pressure can produce a low scroll rate, which facilitates user control of the scroll rate.

Step 10333, when the result of the determination is YES, it is determined that scrolling does not occur.

In this step, if the newly detected pressure value is less than P1, no action can be performed, but the scroll bar can still remain in the controlled scroll state, that is, when the pressure value applied by the user is greater than P1, the touch screen can be immediately controlled. scroll.

At this time, the user can realize real-time adjustment of the scrolling rate of the touch screen by a simple operation, thereby facilitating the use of the user, fully satisfying the user's intention, and improving the practicability and convenience.

Optionally, an area in the display interface of the touch screen that controls information scrolling may include: a scroll bar.

In the above step 1033, the determining the scroll direction according to the location information may include:

Step 10334, when the location indicated by the location information is in an area other than the scroll bar, determining a direction in which the scroll bar moves toward the position indicated by the location information is the scroll direction.

In this step, if the position at which the user performs the touch operation is in an area other than the scroll bar, it may be determined that the direction in which the scroll bar moves to the position indicated by the touch operation is the page scroll direction.

Step 10335, when the position indicated by the location information is on the scroll bar, it is determined that scrolling does not occur.

In this step, if the position where the user performs the touch operation is on the scroll bar, scrolling may not occur. There may be two cases here, one is that the initial position of the user performing the touch operation is not on the scroll bar, the scroll bar moves to the position indicated by the touch operation, and moves to the position indicated by the touch operation to end the scroll; the other is performed by the user. When the initial position of the touch operation is on the scroll bar, the scroll bar does not scroll.

Optionally, the step of step 1034 above may include:

Step 10341, when it is determined that the direction of movement of the scroll bar to the position indicated by the position information is the scroll direction, the display interface of the touch screen is controlled to the scroll direction according to the scroll bar according to the scroll bar. Scrolling and scrolling stops when the scroll bar reaches the position indicated by the location information.

Wherein, for the vertically arranged scroll bar, the top end of the area where the control information is scrolled may be set as the origin, and the position offset L0 of the touch point is calculated, the current top position offset L1 (ie, the top position of the scroll bar) and the current page are respectively calculated. The bottom position is offset by L2 (ie, the bottom end position of the scroll bar). If L0 is less than L1, Then the direction of controlled scrolling is from bottom to top; if L0 is greater than L2, the direction of controlled scrolling is from top to bottom. During the scrolling process, L1 and L2 can be updated in real time according to the content display page position. When scrolling satisfies L1 < L0 < L2, controlled scrolling can end.

At this time, in the controlled scrolling state, the user can scroll the page to the proper position by a simple operation, thereby facilitating the user's use, fully satisfying the user's intention, and improving the practicability and convenience.

Optionally, the area in which the control information is scrolled in the display interface of the touch screen may further include: two end indication areas indicating opposite ends of the area where the control information is scrolled.

Wherein, as shown in FIG. 2, the scroll bar for the longitudinal direction may have two end indication areas A0 and A1 indicating the top of the page and the bottom of the page, respectively.

In the above step 1033, the determining the scroll direction according to the location information may further include:

Step 10336, when the position indicated by the position information is within the end indication area, determining that the direction in which the scroll bar moves toward the end indicated by the end indication area is the scroll direction.

Optionally, the foregoing step 1034 may include:

Step 10342, when it is determined that the direction in which the scroll bar moves toward the end indicated by the end indication area is the scroll direction, the display interface controlling the touch screen is scrolled according to the scroll bar according to the scroll rate. The direction scrolls and scrolls until the scroll bar reaches one end of the end indication area indication.

In this step, the scroll bar set in the longitudinal direction is taken as an example. If the position indicated by the touch operation is in the end indication area, the target area of the scroll may be the top or bottom end of the page of the touch screen display interface. That is, when the A0 area is touched, regardless of the exact value of the touch position offset, the position offset L0 of the touch point can always be set to the top offset position of the display interface; when the A1 area is touched, regardless of the precise touch The value of the offset position is set, and the position offset L0 of the touch point can always be set to the bottom offset position of the display interface. Therefore, when the A0 or A1 area is touched, the touch screen display interface can be scrolled to the top or bottom of the page, respectively.

At this time, the page can be scrolled to the top or bottom of the page through the end indication area, thereby facilitating the user's operation and improving the usability and convenience.

Optionally, after the display interface of the touch screen enters a controlled scroll state, the control The method can also include:

Step 104: Start a timer, where the timing of the timer is greater than a preset number of sampling periods, where the sampling period refers to a period of detecting a touch event of the touch screen, and the user scrolls the control information in the display interface of the touch screen. A touch operation is a touch event.

In this step, when the first touch event is detected and it is determined that the touch event is a press, the timer may be started. For convenience of description, the timing time of the timer is marked as T0, and the preset number is marked as C0, T0. The value is greater than the basic sampling number threshold C0, that is, T0 is greater than C0 sampling periods. Here, C0 can take 3.

Step 105: Determine whether a touch event is detected in the timing time of the timer. When no touch event is detected within the timing time of the timer, the display interface of the touch screen is controlled to exit the controlled scroll state; When the touch event is detected within the timing time of the timer, the pressure information of the touch point is continuously detected.

In this step, it is assumed that C0 is 3. If no touch event input is detected within 3 sampling periods, the controlled scroll state can be exited.

At this time, by setting a timer, the touch screen can enter the controlled scrolling state for a period of time, and can automatically exit without detecting the user's touch operation, thereby improving the practicability and intelligence.

Optionally, the foregoing step 103 may include:

Step 1035, when the touch operation is a tap operation, perform a normal touch operation, such as controlling a display interface of the touch screen to scroll to a position indicated by the position information.

In this step, if the user performs a tap operation, the scroll bar can be controlled to perform a normal touch action even if the display interface scrolls to the position indicated by the touch point. This step is compatible with software implementations in the related art.

The specific implementation of the control method of the touch screen in the embodiment of the present invention is described below with reference to FIG.

FIG. 3 is a flowchart of an optional implementation manner of a method for controlling a touch screen according to an embodiment of the present invention. As shown in FIG. 3, the process includes:

Step 301: Acquire location information and pressure information of the touch point when detecting that the user performs a touch operation on the area where the information is scrolled in the display interface of the touch screen.

In this process, the pressure touch screen is in a normal working state, and the user touches the touch screen. Will be detected. In this step, the position information and the pressure information of the captured event occurrence position can be converted into a digital signal.

The area in which the control information is scrolled in the display interface of the touch screen may include a scroll bar, and may further include two end indication areas at opposite ends of the area indicating the scrolling of the control information.

Step 302: Determine whether the pressure value of the pressure information is less than a preset first pressure threshold P1. When the pressure value of the pressure information is less than the first pressure threshold P1, determine that the touch operation is a tap operation.

Here, the pressing force parameter of the touch event can be compared with the first pressure threshold P1, and if the pressing force is less than P1, a "tap" flag can be added for the touch event.

Step 303: Determine whether the pressure value of the pressure information is greater than a preset second pressure threshold P2. When the pressure value of the pressure information is greater than the second pressure threshold P2, determine that the touch operation is a pressing operation. Among them, P2 ≥ P1.

Here, the pressing force parameter of the touch event can be continuously compared with P2. If the pressing force is greater than P2, a "press" flag can be added for the touch event, and other events do not set the flag.

Step 304, when the touch event is marked as "tap", scroll the display interface of the touch screen to the position indicated by the touch point.

Step 305, when the touch event is marked as "press", the display interface of the touch screen is brought into a controlled scroll state.

Step 306, after the display interface enters the controlled scroll state, continues to detect the pressure information of the touch point.

Step 307: Determine a scroll rate according to the currently detected pressure information.

Determining whether the currently detected pressure value is less than the first pressure threshold P1. When the determination result is no, the result of dividing the currently detected pressure value by the standard pressure value P3 may be used as the rate factor, and the rate factor is multiplied by the standard rate R0. The result is taken as the actual scroll rate. When the result of the determination is YES, it can be determined that scrolling does not occur, but can still remain in a controlled scrolling state.

Step 308, determining a scroll direction according to the location information.

When the position indicated by the position information is in an area other than the scroll bar, it may be determined that the direction of the position movement indicated by the scroll bar to the position information is a scroll direction, and the display interface of the touch screen is controlled to scroll in the scroll direction according to the scroll rate. Scrolling stops when the scroll bar reaches the position indicated by the position information.

When the position indicated by the position information is on the scroll bar, it can be determined that scrolling does not occur.

When the position indicated by the position information is in the end indication area, it may be determined that the direction in which the scroll bar indicates the end movement of the end indication area is the scroll direction, and the display interface controlling the touch screen is scrolled to the scroll direction according to the scroll rate. , scrolls to the end when the scroll bar reaches the end indicated by the end indication area.

For example, in the longitudinally arranged scroll bar, for the vertically arranged scroll bar, there are two end indication areas A0 and A1, which respectively indicate the top of the page and the bottom of the page. The top end of the area where the control information is scrolled may be set as the origin, and the position offset L0 of the touch point is calculated, the current top position offset L1 (ie, the top position of the scroll bar) and the current bottom position offset L2 (ie, the scroll bar) The bottom position)). If L0 is less than L1, then the direction of controlled scrolling is from bottom to top; if L0 is greater than L2, the direction of controlled scrolling is from top to bottom. During the scrolling process, L1 and L2 can be updated in real time according to the content display page position. When scrolling satisfies L1 < L0 < L2, controlled scrolling can end. When the A0 or A1 area is tapped, the touch screen display interface can be scrolled to the top or bottom of the page, respectively.

Step 309: After the display interface enters the controlled scroll state, a timer is started, wherein the timer time T0 of the timer is greater than C0 (eg, 3) sampling periods. The sampling period refers to the period of detecting a touch event of the touch screen.

Step 310: When no touch event is detected within the timing time of the timer, the display interface of the control touch screen exits the controlled scroll state; when the touch event is detected within the timing time of the timer, the above step 306 is continued. Until 308, until the scrolling stops.

In summary, the control method of the touch screen according to the embodiment of the present invention, combined with the pressure information to control the scrolling action of the display interface, can realize flexible control of the scrolling mode of the touch screen, improve the positioning accuracy, and fully satisfy the user's intention, and facilitate the use of the user. , enhance the user experience.
