Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart of a page switching method provided in an embodiment of the present invention, which is applied to a terminal equipped with a flexible screen, and the flexible screen can be folded to have a first screen and a second screen, as shown in fig. 1, including the following steps:

step 101, obtaining a first angle value, a second angle value and a third angle value between a first screen and a second screen in a folding operation process, wherein the folding operation process is a process in which an angle value between the first screen and the second screen continuously changes, the first angle value is an angle value between the two screens at the beginning of the folding operation process, the second angle value is an angle value between the two screens from the close to the open of the first screen and the second screen, and the third angle value is an angle value between the two screens at the end of the folding operation process.

In step 101, the terminal of the present invention is equipped with a flexible screen, and the flexible screen can be folded into two screens, namely, a first screen and a second screen. The first screen and the second screen may be respectively provided with a triaxial gyroscope, the triaxial gyroscope in the first screen may acquire angle information of the first screen relative to a reference plane, and the triaxial gyroscope in the second screen may acquire angle information of the second screen relative to the reference plane. And comparing the angle information of the first screen relative to the reference plane with the angle information of the second screen relative to the reference plane to obtain the angle value between the first screen and the second screen.

The terminal may detect whether an angle value between the first screen and the second screen is changed in real time. When the first screen and the second screen move relatively, the terminal detects that the angle value between the first screen and the second screen changes.

The first screen and the second screen can be relatively close to each other and then relatively spread, so that the angle value between the first screen and the second screen is continuously changed. The process of continuously changing the angle value between the first screen and the second screen can be recorded as a folding operation process, that is, the process of relatively closing the first screen and the second screen and then relatively unfolding the first screen and the second screen can be recorded as a folding operation process. The angle value between the two screens at the beginning of the folding operation is recorded as a first angle value.

When the two screens are relatively closed, the terminal can detect that the angle value between the first screen and the second screen is changed, and can detect that the angle value between the two screens is gradually reduced. When the first screen and the second screen stop relatively approaching, the terminal can detect that the angle value between the two screens is not changed any more, namely, can detect that the angle value between the two screens is not reduced any more. At this time, the terminal may obtain an angle value between the two screens after the first screen and the second screen stop being relatively closed, that is, the terminal may obtain an angle value between the two screens when the first screen and the second screen are unfolded from the close position, and the angle value is recorded as a second angle value.

After the two screens are relatively closed, the two screens can be relatively unfolded. At this time, the terminal detects that the angle between the two screens has changed again within the preset time period, and can detect that the angle between the two screens is gradually increased. When the first screen and the second screen stop being relatively unfolded, the terminal can detect that the angle value between the two screens is not changed any more, that is, can detect that the angle value between the two screens is not increased any more. At this time, the terminal may obtain an angle value between the two screens after the first screen and the second screen stop being relatively unfolded, that is, the terminal may obtain an angle value between the two screens when the folding operation process is finished, and record the angle value as a third angle value.

After the first angle value, the second angle value between the two screens after the first screen and the second screen are relatively close and the third angle value between the two screens after the first screen and the second screen are relatively unfolded are obtained, whether the relation of the first angle value, the second angle value and the third angle value meets the preset condition or not can be further judged.

And 102, if the relation among the first angle value, the second angle value and the third angle value meets a preset condition, switching the page.

In step 102, when the terminal determines that the relationship between the first angle value, the second angle value, and the third angle value satisfies the preset condition, the page switching may be performed on the application on the terminal. The application may be an electronic book or a photo library.

The page switching method of the embodiment of the invention obtains a first angle value, a second angle value and a third angle value between a first screen and a second screen in the folding operation process, wherein the folding operation process is a process of continuously changing the angle value between the first screen and the second screen, the first angle value is the angle value between the two screens at the beginning of the folding operation process, the second angle value is the angle value between the two screens from the approach to the expansion of the first screen and the second screen, and the third angle value is the angle value between the two screens at the end of the folding operation process; and if the relation among the first angle value, the second angle value and the third angle value meets a preset condition, switching the page. Therefore, the first screen and the second screen of the terminal are relatively folded, the first screen and the second screen are relatively unfolded, and when the mutual relation of the angle values between the first screen and the second screen meets the preset condition, page switching can be performed on the application on the terminal, and the terminal is convenient and fast to use. Meanwhile, the false triggering condition is effectively prevented. Moreover, the operation mode is very similar to the mode of turning over books or photo albums in real life, so that the user can remember the operation mode conveniently, and the page switching efficiency is improved.

Fig. 2 is a flowchart of another page switching method provided in an embodiment of the present invention, which is applied to a terminal equipped with a flexible screen, and the flexible screen can be folded to have a first screen and a second screen. As shown in fig. 2, the method comprises the following steps:

step 201, obtaining a first angle value, a second angle value and a third angle value between a first screen and a second screen in a folding operation process, wherein the folding operation process is a process in which an angle value between the first screen and the second screen continuously changes, the first angle value is an angle value between the two screens at the beginning of the folding operation process, the second angle value is an angle value between the two screens from the close to the open of the first screen and the second screen, and the third angle value is an angle value between the two screens at the end of the folding operation process.

In step 201, the terminal of the present invention is equipped with a flexible screen, and the flexible screen can be folded into two screens, namely, a first screen and a second screen. The first screen and the second screen can be respectively provided with a three-axis gyroscope, and the angle value between the first screen and the second screen can be calculated through the three-axis gyroscopes in the two screens.

The first screen and the second screen can be relatively close to each other and then relatively spread, so that the angle value between the first screen and the second screen is continuously changed. The process of continuously changing the angle value between the first screen and the second screen can be recorded as a folding operation process, that is, the process of relatively closing the first screen and the second screen and then relatively unfolding the first screen and the second screen can be recorded as a folding operation process. The angle value between the two screens at the start of the folding operation is noted as a first angle value, and the first angle value is represented by x 1.

It should be noted that when the first screen and the second screen are unfolded to be in a flush state, the angle value between the two screens is marked as 180 degrees; when the first screen and the second screen are folded together, the angle between the two screens is marked as 0 degree.

Typically, the angle between the two screens will be in the range of 90-180 degrees when the user holds the two screens spread apart in both hands. Thus, a range of firing angles may be defined, such as 90-180 degrees. When the folding operation process is started, the angle value between the first screen and the second screen is within the triggering angle range, the first screen and the second screen are folded relatively first and then unfolded relatively, and the application on the terminal is switched when the mutual relation of the angle values between the two screens meets the preset condition.

Moreover, the trigger angle range can be set at will, and a user can set the trigger angle range according to own habits. For example, the user may also set the trigger angle range to 120-180 degrees.

When the first screen and the second screen are relatively closed, the terminal can detect that the angle value between the first screen and the second screen is changed, and can detect that the angle value between the two screens is gradually reduced. When the first screen and the second screen stop relatively approaching, the terminal can detect that the angle value between the two screens is not changed any more, namely, can detect that the angle value between the two screens is not reduced any more. At this time, the terminal may obtain an angle value between the two screens after the first screen and the second screen stop being relatively closed, that is, the terminal may obtain an angle value between the two screens when the first screen and the second screen are unfolded from the close position, and record the angle value as a second angle value, and record the second angle value as x 2.

After the two screens are relatively closed, the two screens can be relatively unfolded. At this time, the terminal detects that the angle between the two screens has changed again within the preset time period, and can detect that the angle between the two screens is gradually increased. When the first screen and the second screen stop being relatively unfolded, the terminal can detect that the angle value between the two screens is not changed any more, that is, can detect that the angle value between the two screens is not increased any more. At this time, the terminal may obtain the angle value between the two screens after the first screen and the second screen stop being relatively unfolded, that is, the terminal may obtain the angle value between the two screens when the folding operation process is finished, and record the angle value as a third angle value, and record the third angle value as x 3.

Step 202, if the second angle value is smaller than or equal to the preset first threshold value, and the absolute value of the difference between the first angle value and the third angle value is smaller than or equal to the preset second threshold value, determining whether the second angle value is larger than a preset third threshold value, where the preset third threshold value is smaller than the preset first threshold value.

In step 202, after the first angle value x1, the second angle value x2 between the two screens after the first screen and the second screen are relatively close, and the third angle value x3 between the two screens after the first screen and the second screen are relatively spread are obtained, it may be further determined whether the relationship among the first angle value x1, the second angle value x2, and the third angle value x3 satisfies a preset condition.

Whether the second angle value x2 is smaller than or equal to a preset first threshold value or not can be determined, that is, whether the angle value between the two screens after the first screen and the second screen are relatively closed together is smaller than or equal to the preset first threshold value or not can be determined. Wherein the preset first threshold is smaller than the minimum value of the triggering angle range. The preset first threshold value can be set arbitrarily, and is denoted as a. For example, the user may set the preset first threshold to 40 degrees, i.e., let a be 40 degrees.

It is also determined whether the absolute value of the difference between the first angle value x1 and the third angle value x3 is less than or equal to a preset second threshold value. The preset second threshold may also be set arbitrarily, and is denoted as b. For example, the user may set the preset second threshold to 15 degrees, i.e., let b be 15 degrees.

If the terminal determines that the second angle value x2 is less than or equal to the preset first threshold a and the absolute value of the difference between the first angle value x1 and the third angle value x3 is less than or equal to the preset second threshold b, it may be further determined whether the second angle value x2 is greater than a preset third threshold. The preset third threshold value can be set arbitrarily, and is denoted as c. For example, the user may set the preset third threshold to 20 degrees, i.e., let c be 20 degrees. Wherein the preset third threshold c is smaller than the preset first threshold a.

Step 203, if the second angle value is smaller than or equal to the preset third threshold, switching the page to the direction in which the page number is smaller than the page number on the first screen.

In step 203, if the terminal determines that the second angle value is less than or equal to the preset third threshold c, i.e. x2 is less than or equal to c, i.e. x2 is less than or equal to 20 degrees, the page is switched in a direction in which the page number is less than the page number on the first screen.

And 204, if the second angle value is larger than a preset third threshold and smaller than or equal to a preset first threshold, and the absolute value of the difference between the first angle value and the third angle value is smaller than or equal to a preset second threshold, switching the page in the direction in which the page number is larger than the page number on the second screen.

In step 204, if the terminal determines that the second angle value x2 is greater than the preset third threshold value c, and the second angle value x2 is less than or equal to the preset first threshold value a, i.e., c < x2 ≦ a, i.e., 20 degrees < x2 ≦ 40 degrees, and the absolute value of the difference between the first angle value x1 and the third angle value x3 is less than or equal to the preset second threshold value b, the page is switched in a direction in which the page number is greater than the page number on the second screen.

Step 205, receiving a first touch operation on a screen of the terminal.

In step 205, after the terminal performs page switching on the application, the terminal may also perform fast page switching on the application. For example, the terminal may detect whether a first touch operation to a screen of the terminal is received.

And step 206, determining a touch track corresponding to the first touch operation.

In step 206, if a first touch operation on the screen of the terminal is received, the terminal may determine a touch trajectory corresponding to the first touch operation.

For example, after page switching is performed in a direction in which the page number is greater than the page number on the second screen, if the user's finger touches the second screen, and slides to the right on the second screen. The terminal detects a first touch operation, and then the terminal determines a touch track corresponding to the first touch operation, namely detects a touch track drawn by a finger of a user when the finger slides on the second screen.

And step 207, acquiring a length value of the touch track.

In step 207, after the terminal determines the touch trajectory, a length value of the touch trajectory may be obtained.

It should be noted that, when performing fast page switching, the number of pages to be switched fast may be directly proportional to the length value of the touch trajectory. For example, the length of the touch trajectory is one centimeter, and the number of pages corresponding to switching may be 10 pages.

And 208, determining a first target page corresponding to the length value of the touch track, and displaying a schematic diagram of the first target page.

In step 208, after the terminal acquires the length value of the touch trajectory, a first target page corresponding to the length value of the touch trajectory may be determined, and a schematic diagram of the first target page is displayed.

For example, assuming that the length value of the touch trajectory is one centimeter, the number of pages corresponding to switching may be 2 pages. Assuming that the currently opened application is an electronic book, after page switching is performed in a direction in which the page number is larger than that on the second screen, the current page number on the first screen is 49, and the current page number on the second screen is 50.

If the user touches the second screen with a finger and slides to the right on the second screen at the moment, the terminal detects a first touch operation, and further determines a touch track corresponding to the first touch operation, namely detects the touch track drawn by the finger of the user when the finger slides on the second screen.

After the terminal detects the touch track, the length value of the touch track can be obtained, a first target page corresponding to the length value of the touch track can be determined, and a schematic diagram of the first target page is displayed.

It should be noted that, when the application performing page switching is an electronic book, in the process of performing fast page switching, only the enlarged page number may be displayed on the page, and the specific content of the page is not displayed.

For example, if the finger of the user slides rightwards for one centimeter on the second screen, the length value of the touch trajectory acquired by the terminal is one centimeter, the page number on the second screen can jump from 50 to 52, at this time, the first target page is the page with the page number of 52, and only the page number of 52 is displayed on the first target page, and the specific content of the page is not displayed; if the finger of the user continues to slide rightwards for one centimeter on the second screen, that is, when the finger of the user slides for two centimeters on the second screen, the length value of the touch track acquired by the terminal is two centimeters, the page number on the second screen can be changed from 52 to 54, at this time, the first target page is the page with the page number of 54, and only the page number of 54 is displayed on the first target page, and the specific content of the page cannot be displayed; if the finger of the user slides one centimeter rightward on the second screen again, that is, when the finger of the user slides three centimeters on the second screen, the length value of the touch trajectory that the terminal can acquire is three centimeters, the page number on the second screen can be jumped from 54 to 56, at this time, the first target page is a page with the page number of 56, and only the page number of 56 is displayed on the first target page, and the specific content of the page cannot be displayed.

Similarly, after the page is switched to the direction in which the page number is smaller than the page number on the first screen, if the user touches the first screen with a finger and slides to the left on the first screen at this time, the page can be quickly switched to the previous page. The specific switching process is similar to the aforementioned process of quickly switching pages to the next page, and is not described herein again.

When the application performing page switching is a photo gallery, only thumbnails, not original images, may be displayed on a page during fast page switching.

Step 209 receives a first page switch stop command.

In step 209, a fast page switch may be achieved when the user's finger slides across the screen. When the finger of the user leaves the screen, the terminal receives a first page switch stop instruction. And the terminal stops performing the fast page switching according to the first page switching stop instruction.

Step 2010, determining a second target page according to the first page switching stop instruction, and displaying the content of the second target page.

In step 2010, after receiving the first page switch stop instruction, the terminal determines a second target page according to the first page switch stop instruction, and displays the content of the second target page.

For example, when the application performing page switching is an electronic book, after receiving a first page switching stop instruction, the terminal determines a second target page according to the first page switching stop instruction, that is, determines a target page number of the electronic book according to the first page switching stop instruction, and displays the content of the second target page, that is, displays the content of the page where the target page number is located; when the application for page switching is a photo library, after receiving a first page switching stop instruction, the terminal determines a second target page according to the first page switching stop instruction, namely determines a target thumbnail according to the first page switching stop instruction, and then displays the content of the second target page, namely displays a target original image corresponding to the target thumbnail.

Therefore, the first screen and the second screen of the terminal are relatively folded, the first screen and the second screen are relatively unfolded, and when the mutual relation of the angle values between the first screen and the second screen meets the preset condition, page switching can be performed on the application on the terminal, and the terminal is convenient and fast to use. And moreover, the application can be rapidly switched. Meanwhile, the false triggering condition is effectively prevented. Moreover, the operation mode is very similar to the mode of turning over books or photo albums in real life, so that the user can remember the operation mode conveniently, and the page switching efficiency is improved.

Fig. 3 is a flowchart of another page switching method provided in an embodiment of the present invention, which is applied to a terminal equipped with a flexible screen, and the flexible screen can be folded to have a first screen and a second screen. As shown in fig. 3, the method comprises the following steps:

step 301, obtaining a first angle value, a second angle value and a third angle value between a first screen and a second screen in a folding operation process, wherein the folding operation process is a process in which an angle value between the first screen and the second screen continuously changes, the first angle value is an angle value between the two screens at the beginning of the folding operation process, the second angle value is an angle value between the two screens from the close to the open of the first screen and the second screen, and the third angle value is an angle value between the two screens at the end of the folding operation process.

Step 302, if the absolute value of the difference between the first angle value and the second angle value is greater than or equal to the preset fourth threshold, and the absolute value of the difference between the third angle value and the second angle value is greater than or equal to the preset fourth threshold, it is determined whether the second angle value is greater than the preset fifth threshold.

In step 302, after the first angle value x1, the second angle value x2 between the two screens after the first screen and the second screen are relatively close, and the third angle value x3 between the two screens after the first screen and the second screen are relatively spread are obtained, it can be further determined whether the relationship among the first angle value x1, the second angle value x2, and the third angle value x3 meets the preset condition.

It may be determined whether the absolute value of the difference between the first angle value x1 and the second angle value x2 is greater than or equal to a preset fourth threshold. The preset fourth threshold value can be set arbitrarily, and is denoted as d. For example, the user may set the preset fourth threshold to 60 degrees, i.e., let d be 60 degrees. That is, the terminal can determine whether | x1-x2| ≧ d is true, that is, whether | x1-x2| ≧ 60 degrees is true.

The terminal may further determine whether an absolute value of a difference between the third angle value x3 and the second angle value x2 is greater than or equal to a preset fourth threshold value d. That is, the terminal can determine whether | x3-x2| ≧ d is true, that is, whether | x3-x2| ≧ 60 degrees is true.

If the terminal determines that the absolute value of the difference between the first angle value x1 and the second angle value x2 is greater than or equal to a preset fourth threshold d, and the absolute value of the difference between the third angle value x3 and the second angle value x2 is greater than or equal to the preset fourth threshold d, that is, if the terminal determines that | x1-x2| ≧ d is true and | x3-x2| ≧ d is true, that is, if the terminal determines that | x1-x2| ≧ 60 degrees is true and | x3-x2| ≧ 60 degrees is true, the terminal may further determine whether the second angle value x2 is greater than a preset fifth threshold. The preset fifth threshold may be set arbitrarily, and may be denoted as e. For example, the user may set the preset fifth threshold to 30 degrees, i.e., let e be 30 degrees. That is, the terminal can determine whether x2>30 degrees holds.

Step 303, if the second angle value is smaller than or equal to the preset fifth threshold, switching the page to a direction in which the page number is smaller than the page number on the first screen.

In step 303, if the terminal determines that the second angle value x2 is less than or equal to a preset fifth threshold e, i.e. x2 is less than or equal to e, i.e. x2 is less than or equal to 30 degrees, the page is switched to a direction in which the page number is less than the page number on the first screen.

And step 304, if the second angle value is larger than a preset fifth threshold, switching the page to the direction in which the page number is larger than the page number on the second screen.

In step 304, if the terminal determines that the second angle value x2 is greater than a preset fifth threshold value e, i.e., x2> e, i.e., x2>30 degrees, the page is switched in a direction in which the page number is greater than the page number on the second screen.

Optionally, the page switching is performed, including:

judging whether the angle value between the first screen and the reference plane is changed in the folding operation process;

judging whether the angle value between the second screen and the reference plane is changed in the folding operation process;

if the angle value between the first screen and the reference plane is changed in the folding operation process and the angle value between the second screen and the reference plane is not changed in the folding operation process, page switching is carried out in the direction that the page number is smaller than the page number on the first screen;

and if the angle value between the second screen and the reference plane is changed in the folding operation process and the angle value between the first screen and the reference plane is not changed in the folding operation process, switching the page to the direction in which the page number is larger than the page number on the second screen.

When the first screen and the second screen are relatively close to each other and then relatively spread, the two screens can both generate motion. It may also be the case that the change in the value of the angle between the first screen and the second screen occurs because the first screen remains stationary with respect to the reference plane and the second screen acts with respect to the first screen; alternatively, the change in the value of the angle between the first screen and the second screen occurs because the second screen remains stationary relative to the reference plane and the first screen moves relative to the second screen. Wherein the reference plane may be a horizontal plane.

The terminal may determine whether an angle value between the first screen and the reference plane is changed during the folding operation and whether an angle value between the second screen and the reference plane is changed during the folding operation. If the terminal judges that the angle value between the first screen and the reference plane is changed in the folding operation process and the angle value between the second screen and the reference plane is not changed in the folding operation process, namely the change of the angle value between the first screen and the second screen is caused by the fact that the second screen is kept still relative to the reference plane and the first screen acts relative to the second screen, namely the change of the angle value between the first screen and the second screen is caused by the fact that the second screen is kept still, only the first screen is folded and the first screen is unfolded, and page switching is carried out in the direction in which the page number is smaller than the page number on the first screen.

If the terminal judges that the angle value between the second screen and the reference plane is changed in the folding operation process and the angle value between the first screen and the reference plane is not changed in the folding operation process, namely the change of the angle value between the first screen and the second screen is caused by the fact that the first screen is kept still relative to the reference plane and the second screen acts relative to the first screen, namely the change of the angle value between the first screen and the second screen is caused by the fact that the first screen is kept still, only the second screen is folded and the second screen is unfolded, and page switching is carried out in the direction in which the page number is larger than the page number on the second screen.

And 305, receiving a second touch operation on the screen of the terminal.

In step 305, after the terminal performs page switching on the application, the terminal may also perform fast page switching on the application. For example, the terminal may detect whether a second touch operation to the screen of the terminal is received.

And step 306, determining a touch track corresponding to the second touch operation.

In step 306, if a second touch operation on the screen of the terminal is received, the terminal may determine a touch trajectory corresponding to the second touch operation.

For example, the second screen is kept still, only the first screen is folded, and then the first screen is unfolded, so that the page switching is performed in the direction in which the page number is smaller than that on the first screen. Then if the user's finger touches the first screen and slides to the left on the first screen. The terminal detects a second touch operation, and further determines a touch track corresponding to the second touch operation, namely detects a touch track drawn by a finger of a user when the finger slides on the first screen.

And 307, acquiring the sliding speed of the touch track.

After the terminal determines the touch trajectory, the sliding speed of the touch trajectory may be acquired in step 307.

It should be noted that, when performing fast page switching, the number of pages to be switched fast may be directly proportional to the sliding speed of the touch trajectory.

And 308, determining a third target page corresponding to the sliding speed of the touch track, and displaying a schematic diagram of the third target page.

In step 308, after the terminal acquires the sliding speed of the touch trajectory, it may determine a third target page corresponding to the sliding speed of the touch trajectory, and display a schematic diagram of the third target page.

The number of pages that switch fast can be directly proportional to the speed of sliding of touch trajectory, and the speed of sliding is the bigger, and the number of pages that switch fast is more, and the finger that also means the user slides on the screen the faster, and the number of pages that switch fast is more.

When the application for switching the page is an electronic book, only the amplified page number can be displayed on the page without displaying the specific content of the page in the process of fast switching the page; when the application performing page switching is a photo gallery, only thumbnails, not original pictures, may be displayed on a page in the process of performing fast page switching.

Optionally, the first target page is an enlarged page number.

As described above, when the application performing the page switching is an electronic book, in the process of performing the fast page switching, the schematic diagram of the first target page may be an enlarged page number.

Optionally, the third target page is an enlarged page number.

As described above, when the application performing the page switching is an electronic book, in the process of performing the fast page switching, the schematic diagram of the third target page may be an enlarged page number.

Step 309, receiving a second page switch stop instruction.

In step 309, when the user's finger slides on the screen, a fast page switch can be achieved. When the finger of the user leaves the screen, the terminal receives a second page switching stop instruction. And the terminal stops performing the fast page switching according to the second page switching stop instruction.

And 3010, determining a fourth target page according to the second page switching stop instruction, and displaying the content of the fourth target page.

In step 3010, after receiving the second page switch stop instruction, the terminal determines a fourth target page according to the second page switch stop instruction, and displays the content of the fourth target page.

For example, when the application performing page switching is an electronic book, after receiving a second page switching stop instruction, the terminal determines a fourth target page according to the second page switching stop instruction, that is, determines a target page number of the electronic book according to the second page switching stop instruction, and displays the content of the fourth target page, that is, displays the content of the page where the target page number is located; when the application for page switching is a photo gallery, after receiving a second page switching stop instruction, the terminal determines a fourth target page according to the second page switching stop instruction, namely determines a target thumbnail according to the second page switching stop instruction, and further displays the content of the fourth target page, namely displays a target original image corresponding to the target thumbnail.

Therefore, the first screen and the second screen of the terminal are relatively folded, the first screen and the second screen are relatively unfolded, and when the mutual relation of the angle values between the first screen and the second screen meets the preset condition, page switching can be performed on the application on the terminal, and the terminal is convenient and fast to use. Meanwhile, the false triggering condition is effectively prevented. Moreover, the operation mode is very similar to the mode of turning over books or photo albums in real life, so that the user can remember the operation mode conveniently, and the page switching efficiency is improved.
