Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a speed compensation method for a sliding operation according to an embodiment of the present invention, where the speed compensation method for a sliding operation according to an embodiment of the present invention may be implemented by a speed compensation device for a sliding operation, and the speed compensation device for a sliding operation may be implemented by software and/or hardware. As shown in fig. 1, the speed compensation method of the sliding operation includes:
and step 110, when the user performs sliding operation on the current display interface, determining the interface quality of the current display interface according to a preset method.
In the embodiment of the invention, mobile devices like mobile phones, tablet computers and the like can be provided with the touch screen. The touch screen may include a plurality of display interfaces, and since the plurality of display interfaces may not be simultaneously displayed on one touch screen, the plurality of display interfaces may need to be switched to be respectively displayed, that is, the plurality of display interfaces on the touch screen need to be alternately switched to be displayed by performing a sliding operation. The sliding operation may be a behavior of sliding switching of a certain display interface on the touch screen by a user, for example, scrolling the certain display interface on the touch screen up and down, scrolling the certain display interface on the touch screen left and right, and moving the certain display interface on the touch screen to view information at different positions of the certain display interface.
Illustratively, the touch screen includes 4 display interfaces, which are an interface a, an interface B, an interface C, and an interface D, respectively, and the current display interface is set as the interface a. On one hand, when a user needs to display the B interface on the touch screen, the sliding operation needs to be performed on the current display interface to realize switching from the A interface to the B interface. On the other hand, when the length and the width of the interface a displayed on the touch screen are large, the information content on the interface a cannot be simultaneously and completely displayed on the touch screen, and if the interface a is zoomed, the information content on the interface a cannot be clearly seen, the interface a can be slid on the touch screen, so that the information content at different positions on the interface a can be clearly displayed on the touch screen, and a user can conveniently view the information at different positions on the interface a. The above is not limited to the touch screen, and other display screens may be used, and other screens having pressure sensing may be used.
In the embodiment of the invention, the preset method can be a method for pre-calculating the quality of the display page according to the setting of the display interface, and the quality of the display interface is pre-calculated and stored so as to be convenient for calling after the quality of the display interface is used subsequently.
And step 120, acquiring each target acting force on the current display interface in the effective time period from the beginning to the end of the sliding of the user according to a preset frequency.
In the embodiment of the present invention, the start sliding time may be a starting time when the user performs any sliding operation on the touch screen, and initially contacts the touch screen or initially applies pressure to the touch screen in a certain sliding operation to perform the sliding operation on the display interface. Accordingly, the end sliding time may be an end time when the user finally leaves the touch screen or no longer applies pressure to the touch screen in a certain sliding operation to perform the sliding operation on the display interface. For example, when the user is performing the sliding operation, a starting time for pressing the touch screen by a starting finger or applying pressure to the touch screen to cause the display interface to perform the sliding operation may be used as the starting sliding time. Accordingly, a point of time at which a transition from a state in which the finger presses the touch screen to a state in which the finger leaves the touch screen or a transition from a state in which the user applies pressure to the touch screen to a state in which pressure is no longer applied to the touch screen may be taken as the end sliding time.
In the embodiment of the invention, when a user starts to touch and slide a current display interface on a touch screen to finish the touch and slide within a time period, the current display interface can continuously acquire a horizontal pressure applied to the surface of the touch screen by the user according to a preset sampling frequency, and the horizontal pressure can be used as a target acting force acquired by the current display interface. Since the display interface can acquire the target acting force according to the preset frequency in the time period from the start of the touch sliding to the end of the touch sliding, the target acting force acquired by the display interface in the effective time period may include a plurality of target acting forces with different magnitudes. That is, the display interface may obtain the target acting force acquired at each time point at preset time intervals during the time period from the start of the touch slide to the end of the touch slide. According to nyquist's theory, the higher the preset sampling frequency, i.e. the shorter the sampling interval, the greater the number of target forces acquired by the display interface per unit time, especially when the preset sampling interval is set to be particularly short, the set of target forces acquired by the display interface can be approximately regarded as a function of time.
And step 130, calculating the compensation sliding speed corresponding to the current display interface according to the interface quality and each target acting force.
In the embodiment of the invention, when the user is in the effective time period from the beginning of touch sliding to the end of touch sliding on the touch screen, the current display interface can continuously acquire each target acting force and acquire the quality of the current display interface. According to the defined quality of the current display interface and the target acting force acquired by the current display interface, according to Newton mechanics and kinematics, the current display interface can be acted by the target acting force within an effective time period to generate corresponding acceleration, the direction of the acceleration is the same as that of the target acting force, and the magnitude of the acceleration is in direct proportion to that of the target acting force and is in inverse proportion to the quality of the current display interface.
Generally, after the display interface performing the sliding operation is subjected to a target acting force different from zero, the current display interface may generate an acceleration, so that the motion state or speed of the current display interface is changed, for example, the sliding speed of the current display interface is increased or decreased. However, in the prior art, because the quality of the display interface is not defined, the sliding speed of the display interface is only the initial speed of the sliding start when the display interface slides along with the hand, that is, the speed of the finger leaving the screen at the moment of release, so that the instant force action of the target acting force of the user on the touch screen in the effective time period from the start of the touch sliding to the end of the touch sliding on the current display interface is ignored, and the influence of the instant force action on the acceleration, the motion state and the speed of the current display interface is further ignored. Therefore, the neglected speed in the display interface can be quantitatively analyzed according to the quality of the current display interface and each target acting force, the neglected change values of the acceleration, the motion state and the speed in the effective time period of the target acting force acquired by the current display interface are compensated, and the compensated sliding speed of the display interface is calculated.
And 140, determining a target sliding speed corresponding to the display interface according to the compensation sliding speed and the initial sliding speed corresponding to the display interface.
In the embodiment of the invention, the touch screen can detect the speed of a user when the user performs the sliding operation on the touch screen, and the initial sliding speed of the display interface can be detected through the detection function of the touch screen, namely the speed of the moment when the user performs the sliding operation and the finger leaves the surface of the touch screen, and the sliding speed is transmitted to the display interface as the initial sliding speed of the current display interface. After determining the compensated sliding speed of the current display interface during the sliding process, step 130 may sum the initial sliding speed of the current display interface and the compensated sliding speed of the current display interface, and use the sum result as the target sliding speed of the current display interface for performing the scrolling display.
According to the speed compensation method for the sliding operation, provided by the embodiment of the invention, the compensation sliding speed of the current display interface in the effective time period from the sliding start to the sliding end is calculated according to the quality of the current display interface and each target acting force acquired by the current display interface, and then the sliding speed of the current display interface is determined according to the compensation sliding speed and the initial sliding speed of the current display interface. The embodiment of the invention solves the problem that the user can not intuitively adjust the current display interface according to the pressure applied to the touch screen and the sliding speed on the screen, reduces the misoperation caused by the fact that the user can not grasp the pressure of the finger of the user on the touch screen, and improves the accuracy rate of the sliding operation of the screen of the mobile terminal and the user experience effect.
Example two
Fig. 2 is a schematic flow chart of a speed compensation method for a sliding operation according to a second embodiment of the present invention, and this embodiment further optimizes the step of determining the interface quality of the current display interface according to a preset method based on the first embodiment. As shown in fig. 2, the speed compensation method of the sliding operation includes:
and step 210, when the user performs sliding operation on the current display interface, determining the types and the number of all the application programs in the current display interface.
Generally, each display interface may contain a plurality of interface controls. Interface controls refer to visual graphic "elements" such as buttons, file editing boxes, etc. which can be placed on a form, and most interface controls have a function of executing or causing code to run and complete a response through an "event". For example, when the touch screen includes four display interfaces, i.e., an interface a, an interface B, an interface C, and an interface D, and the interface a is set as the current display interface on the touch screen, the interface a may include a plurality of interface controls.
In the embodiment of the present invention, the interface control in the display interface may be different types of application programs in the display interface, for example, application programs corresponding to icons such as "QQ", "pay for use", and "WeChat" in the current display interface in the mobile phone screen. Optionally, when the user performs a sliding operation on the current display interface of the touch screen, the types and the number of all the applications in the current display interface may be determined. For example, before or while the user performs a sliding operation on the current display interface, the types and the number of all the applications that can be seen in the current display interface are determined, such as the types and the number of the applications representing "QQ", "pay for money", and "WeChat".
In the embodiment of the present invention, the interface control in the display interface is not limited to an application program, and may be any type of control constituting the display interface in the display interface or a certain specific control with quality attribute added in the display interface. Illustratively, when a programmer designs a page, a large number of controls are used to optimize a display interface, for example, "button", "edit box", and "prompt bar" may all be interface controls. Or when the quality of the display interface is defined, adding a specific control with a quality attribute in the display interface. For example, "color of page" may also be used as a control for displaying the interface, and the darker the color, the higher the quality, and the lighter the color, the lower the quality, although other types of specific controls with quality attributes may be used.
And step 220, calculating the interface quality according to the types and the quantity of all the application programs.
In the embodiment of the invention, different types and different quantities of controls can be preset in the display interface, and then a virtual quality is defined for each control definition in the display interface according to the preset different types of controls in the display interface, wherein the defined qualities of the controls can be the same or different. And calculating the quality of each display interface according to the preset quantity of the controls and the quality defined by each control, and storing the quality of each display interface. When it is detected that the user slides the display interface on the touch screen, the quality of the display interface currently being slid can be determined according to the stored quality of each display interface.
In an alternative implementation of the embodiment of the present invention, the interface quality may be calculated according to the type and number of all applications.
Specifically, the types and the number of all the applications in each display interface may be predefined, a virtual quality may be defined for each application according to the types of the applications, and then the quality of each display interface may be calculated according to the number of the applications in the display interface. Preferably, when the application program quality in the display interface is defined, the same quality can be set for any application program in the display interface regardless of the type of the application program, then the quality of the display interface is defined according to the difference of the application program quantity in the display interface, and meanwhile, through the difference of the application program quantity in the display interface, which one of the display interfaces is heavier and which one is lighter can be visually observed, so that the sliding operation can be more visually performed on the display interface.
It should be noted that, when the type and/or the number of the controls in each display interface are changed, the quality of each display interface may be recalculated according to the type and/or the number of the controls in the display interface, and the calculated quality of each display interface is updated and stored.
And step 230, acquiring each target acting force on the current display interface in the effective time period from the beginning to the end of the sliding of the user according to a preset frequency.
And 240, calculating the compensation sliding speed corresponding to the current display interface according to the interface quality and each target acting force.
And step 250, determining a target sliding speed corresponding to the display interface according to the compensation sliding speed and the initial sliding speed corresponding to the display interface.
The speed compensation method for the sliding operation, provided by the embodiment of the invention, quantitatively analyzes the quality setting of the display interface, calculates the compensation sliding speed of the current display interface within the effective time period from the sliding start to the sliding end according to the quality of the set display interface and each target acting force acquired by the display interface, and then determines the sliding speed of the current display interface according to the compensation sliding speed and the initial sliding speed of the current display interface. The method and the device solve the problem that the user cannot define the quality of the display interface according to the type and the number of the application programs in the display interface to visually adjust the sliding speed of the current display interface, reduce misoperation caused by inaccurate pressure applied to the touch screen by the user due to the fact that the user cannot grasp the quality of the display interface, and improve the accuracy rate of the sliding operation of the screen of the mobile terminal and the user experience effect.
EXAMPLE III
Fig. 3 is a flowchart illustrating a speed compensation method for a sliding operation according to a third embodiment of the present invention, where the present embodiment further optimizes the step of obtaining each target acting force of the user in the effective time period from the start of the sliding to the end of the sliding according to a preset frequency on the basis of the first embodiment and the second embodiment. As shown in fig. 3, the speed compensation method of the sliding operation includes:
and 310, when the user performs sliding operation on the current display interface, determining the interface quality of the current display interface according to a preset method.
And 320, acquiring each original acting force of the user on the current display interface in the effective time period according to the preset frequency.
In the embodiment of the invention, the touch screen can detect pressure in any direction continuously applied to the surface of the touch screen when a user performs a sliding operation on the touch screen within an effective time period from the start of the touch sliding to the end of the touch sliding on the touch screen by the user at preset time intervals, and then the display interface can acquire the pressure in any direction and magnitude and take the pressure in any direction as an original acting force. Since the touch screen can obtain the target acting force obtained at each time point according to the preset time interval in the time period from the start of the touch slide to the end of the touch slide, an original acting force can be obtained at each time point in the process, and the original acting force is transmitted to the display interface. Then the display interface may capture a plurality of original forces during the time period from the beginning of the touch swipe to the end of the touch swipe. Wherein, since the pressure applied by the user to the touch screen surface can be different directions and different magnitudes of pressure, the pressure (i.e., the original force) applied by the user to the touch screen surface can be a vector having a direction and a magnitude.
In the embodiment of the present invention, the original acting force may be different directions and different magnitudes of pressure applied to the touch screen surface by the user, and the pressures are obtained by sampling the pressure applied to the touch screen surface by the user in any direction and magnitude according to the preset time interval. When the set time interval is smaller and the sampling frequency is higher, the quantity of the pressure which is acquired by the touch screen and applied to the surface of the touch screen by the user in different directions and different magnitudes is larger. In particular, if the set time interval is sufficiently small, the respective original effect captured by the display interface can be approximated as a function of time. For example, when the start sliding time is t1 and the end touch sliding time is t2, original acting forces N in different directions and different magnitudes are applied to the touch screen by the finger of the user in the time period from t1 to t2, a corresponding relation that the original acting forces change along with time can be obtained by sampling the pressure applied to the touch screen by the user, and a function N (t) of the original acting forces along with time can be obtained according to the corresponding relation between the time and the original acting forces N.
In the embodiment of the invention, after the touch screen detects the original acting force applied to the surface of the touch screen by the user, the touch screen can transmit the detected original acting force to the display interface which is executing the sliding operation in real time, and the display interface can acquire the original acting force.
In the embodiment of the present invention, the predetermined component coefficient may be a weight coefficient of the original acting force acquired by the current display interface in the horizontal direction. Because the original acting force acquired by the current display interface is a vector with a direction and a magnitude, when the display interface acquires the target acting force in the horizontal direction, the calculation needs to be performed according to the direction and the magnitude of each original acting force in each original acting force. That is, the target acting force can be calculated according to the original acting force through the mapping relation between the original acting force and the target acting force. The predetermined component coefficient may be a mapping between the original applied force and the target applied force. For example, the original acting force is set to be n (t), the component coefficient of the original acting force in the horizontal direction is δ, and then the target acting force f (t) is δ n (t), so that the target acting force acquired by the current display plane in the horizontal direction can be determined according to the magnitude and direction of each original acting force. The horizontal target acting force is pressure applied to the display interface in the horizontal direction determined by taking the touch screen as a reference object, and is not specific horizontal pressure parallel to the horizontal plane in the terrestrial coordinate system.
On the basis of the foregoing embodiment, this embodiment provides an alternative implementation manner, before calculating each target acting force according to the predetermined component coefficient and each original acting force, the method further includes:
determining a sliding mode of a user during sliding operation on a current display interface; wherein, the sliding mode includes but not limited to: low angle sliding, medium angle sliding, or high angle sliding; the component coefficients are determined according to a sliding manner.
In the embodiment of the invention, since the pressure applied to the touch screen surface by the user has different directions and different magnitudes, that is, each original acting force may have different directions and magnitudes, when each target acting force is calculated according to the original acting force and the component coefficient, the component coefficient corresponding to each original acting force in the horizontal direction is different. That is, the component coefficient may change over time in calculating the target applied force from the multiplication of the original applied force and the component coefficient. In order to more accurately obtain the component coefficient of the original acting force in the horizontal direction, it is also necessary to determine the sliding mode of the user when the user performs the sliding operation on the current display interface in advance. The sliding mode may include a low-angle sliding mode, a middle-angle sliding mode, or a high-angle sliding mode. And then determining component coefficients corresponding to different sliding modes according to the sliding modes.
For example, when it is detected that the sliding manner in which the user applies pressure to the surface of the touch screen is an intermediate angle sliding manner, that is, when an included angle between the direction in which the user applies pressure and the touch screen is 30 ° to 60 °, the value of the component coefficient δ at this time may be set to 0.5; when it is detected that the sliding manner in which the user applies pressure to the surface of the touch screen is high-angle sliding, that is, when an included angle between the direction in which the user applies pressure and the touch screen is 60 ° to 90 °, the value of the horizontal component coefficient δ at this time may be set to 0.3. The target force can then be quickly calculated based on the component coefficients and the original force. The angle range corresponding to the sliding system may be set by itself as needed, and is not fixed. The value of the component coefficient δ may also be set to other values according to actual needs.
And 340, calculating the compensation sliding speed corresponding to the current display interface according to the interface quality and each target acting force.
And 350, determining a target sliding speed corresponding to the display interface according to the compensation sliding speed and the initial sliding speed corresponding to the display interface.
According to the speed compensation method for the sliding operation, provided by the embodiment of the invention, the compensation sliding speed of the current display interface in the effective time period from the sliding start to the sliding end is calculated according to the quality of the current display interface and each target acting force acquired by the current display interface, and then the sliding speed of the current display interface is determined according to the compensation sliding speed and the initial sliding speed of the current display interface. The embodiment of the invention solves the problem that the sliding speed of the display interface cannot be intuitively adjusted according to the pressure applied by the finger of the user on the touch screen, realizes the adjustment of the actual sliding speed of the display interface by applying different pressures to the surface of the touch screen when the user executes the sliding operation, and improves the accuracy rate of the sliding operation of the screen of the mobile terminal and the user experience effect.
Example four
Fig. 4 is a schematic flow chart of a speed compensation method of a sliding operation according to a fourth embodiment of the present invention, and this embodiment further optimizes the step of calculating the sliding speed compensation corresponding to the current display interface according to the interface quality and the target acting force based on the foregoing embodiments. As shown in fig. 4, the speed compensation method of the sliding operation includes:
and step 410, when the user performs sliding operation on the current display interface, determining the interface quality of the current display interface according to a preset method.
And step 420, acquiring each target acting force on the current display interface in the effective time period from the beginning to the end of the sliding of the user according to the preset frequency.
And 430, calculating the corresponding acceleration of the display interface according to the interface quality and each target acting force.
Generally, a force is a cause of acceleration of an object, acceleration of the object is generated when the object is subjected to an external force, or a force is a cause of a change in speed of the object. In the embodiment of the invention, the acceleration corresponding to the display interface is the ratio of the target acting force acquired by the display interface to the display interface quality according to Newton mechanics and kinematics. It should be noted that, in the foregoing embodiment, it has been described that the target acting force may be approximated as a function of time, and the corresponding acceleration of the display interface may also be a function of time within an effective time period from the start of the touch slide to the end of the touch slide on the touch screen. Illustratively, when the target pressure function in the horizontal direction acquired by the display interface is f (t), and the current display interface quality is m, an acceleration function a (t) of the current display interface is obtained by calculation according to an acceleration formula, where the acceleration function a (t) of the current display interface is a function that changes with time.
In the embodiment of the invention, the touch screen can continuously detect the original acting force applied to the touch screen by the user according to the preset frequency, and the display interface can acquire the corresponding original acting force again. When the preset frequency is higher, namely the preset time interval is shorter, the number of the original acting forces acquired by the display interface is larger, and when the preset frequency is high enough, each original acting force acquired by the display interface can be gathered to be approximate to a continuous function which is changed along with time. In practice, however, the complexity of calculation is increased if the display interface acquires too many original forces, and therefore the acquired original forces can be processed. One option is: and averaging the obtained original acting forces, and taking the average as the original acting force obtained by the display interface in the effective time period from the start of sliding to the end of sliding of the user. In the calculation of the average value of each original acting force, the original acting force obtained at some preset point can be calculated, but not all the original acting forces. Another alternative is: and calculating subsequent acceleration by taking the original acting force at the middle position in the acquired original acting forces as the original acting force acquired by the display interface in the effective time period from the start of sliding to the end of sliding.
And step 440, calculating the compensation sliding speed corresponding to the current display interface according to the acceleration corresponding to the display interface and the effective time period.
In the embodiment of the present invention, the valid time period may be a time period during which the touch screen detects that the user generates acceleration in a time period from the beginning of the touch slide to the end of the touch slide on the touch screen.
