In order to realize that whether the user knocks the desktop to vibrate twice continuously is judged through a sensor for sensing vibration in the terminal to realize that the electronic book is turned pages, in some embodiments, whether the triggering condition for turning pages of the electronic book currently displayed by the terminal is met by monitoring a vibration signal generated by the user knocking the desktop is judged, and the method comprises the following steps:

Referring to fig. 4, a method for controlling a page turning of an electronic book displayed by a terminal according to an embodiment of the present application includes the following specific steps:

Step S201, a user opens a reading app on a mobile phone, opens an electronic book to be read, enters a reading page, and places the mobile phone on a bracket or a desktop;

step S202, a user double-clicks a desktop, a page turning system service module (a specific workflow is illustrated later) in the mobile phone receives a clicking signal, and whether the double-clicks the desktop is a continuous double-clicking event is judged;

Step S203, when the page turning system service module judges that the double-click event in the step S202 is an event of continuously clicking the desktop twice, the page turning system service module executes page turning operation to realize the page turning operation of the electronic book;

the page turning system service module can be built in a mobile phone or one module in a reading app; when the page turning system service module is arranged in the mobile phone, all reading apps in the mobile phone can adopt the page turning function; when the page turning system service module is only one module in the reading app, only the reading app is supported to adopt the page turning function; in the following embodiments, the service module of the page turning system is taken as an example to be built in the mobile phone.

The above-mentioned page turning system service module, see fig. 5, for example, is composed of a state control unit 100, an event detection unit 200, and a page turning control unit 300, and the interaction process between them is see fig. 6, specifically:

The state control unit 100 (specific workflow is illustrated later) is configured to determine whether a reading app opened by a user in the current mobile phone is running in the foreground (i.e. the app is running), and if the reading app is running in the foreground and has entered a reading page, the state control unit 100 changes a state flag of the reading app to be started, so that the subsequent event detection unit 200 and the page turning control unit 300 can read the state flag of the reading app and start respective functions; if the reading app is not running in the foreground, or running in the foreground but not entering the reading page, the state control unit 100 changes the state flag of the reading app to be turned off, so that the subsequent event detection unit 200 and the page turning control unit 300 can read the state flag of the reading app and turn off the respective functions;

the event detection unit 200 (specific workflow will be illustrated later) is used to determine whether the user double-clicks the desktop event is a continuous double-clicking desktop event. The event detection unit 200 receives (x, y, z) three-dimensional data values of sensor data (i.e., acceleration values of the mobile phone in x, y, z directions) in real time by registering an acceleration sensor in the mobile phone, referring to fig. 7, according to a placement mode of the mobile phone, selects one of the dimension values as an input signal of subsequent calculation;

The acceleration sensor is a sensor capable of sensing acceleration and converting the acceleration into a usable output signal, the inclination angle of the mobile phone relative to the horizontal plane can be calculated by measuring the acceleration caused by gravity, and the acceleration sensor is arranged in the mobile phone generally;

the registration refers to that in order to acquire acceleration real-time data of the three-dimensional direction of the mobile phone, a program interface provided by an operating system of the mobile phone is needed to use an acceleration sensor;

the vibration generated by the user striking the desktop is up-down vibration, and the mobile phone is placed on the desktop to generate weak up-down vibration, and according to the intrinsic coordinate system of the mobile phone (see fig. 7 for example in the following description), when the angles of the mobile phone placement are different, the acceleration values in the x, y and z directions are different (for example in the following description), so the event detection unit 200 selects the data sequence in the dimension that is most capable of sensing the vibration condition by the following method:

if the mobile phone vertical screen is placed on the bracket, and the included angle between the plane of the mobile phone screen and the desktop is greater than 0 degrees and less than or equal to 45 degrees, the z value is used, see fig. 8a;

if the mobile phone vertical screen is placed on the bracket and the included angle between the plane of the mobile phone screen and the desktop is larger than 45 degrees and smaller than 90 degrees, the y value is used, see fig. 8b;

If the mobile phone transverse screen is placed on the bracket and the included angle between the mobile phone screen and the desktop is larger than 45 degrees and smaller than 90 degrees, the x value is used, see fig. 8c;

The event detection unit 200 performs digital high-pass filtering and shaping processing on the selected one-dimensional data which can most sense the vibration condition, and finally converts the knocked vibration signal into a time signal corresponding to the occurrence of the knocked event, and determines whether the desktop is continuously knocked twice events according to the adjacent two time intervals. If the desktop is continuously knocked twice, a control signal is sent to the page turning control unit 300;

The page turning control unit 300 (the specific workflow is illustrated later) simulates a human hand to click (or slide) on a mobile phone screen in a calling mode, and executes a group of system calls after receiving a control signal sent by the event detection unit 200, so as to realize page turning operation control on the book-reading app;

the system call refers to a program interface provided by the mobile phone operating system for triggering click or sliding screen effect, wherein specific position of clicking the mobile phone screen is described in the following.

Referring to fig. 9, the implementation and workflow of the above state control unit specifically includes:

step S91, presetting a reading app package name list in a mobile phone;

The package names of the commonly used reading type apps in the market are stored in the mobile phone in the form of an array character string resource, and the recording format is 'complete package name/complete class name'; after the mobile phone is started for the first time, reading the array character string resource, and storing in a manner of persistent storage SHAREPREFERENCE key-value pairs (key-value) provided by an operating system, wherein a 'complete package name/complete class name' is used as a key value, the value is used for supporting or not supporting, the type is a Boolean value, and under the default condition, the value values are true and are used for supporting the page turning function for all reading apps stored in the mobile phone in advance;

Step S92, adding or deleting preset reading app operation of the mobile phone on the interaction page by a user;

providing an interactive page (illustrated in the following) to the user in the state control unit, for example, where the user can add and remove reading class apps; the removal is not to unload the reading app from the mobile phone or prohibit the use, but to write a value corresponding to the reading app to be removed as false, and for the reading app to be removed, the mobile phone does not provide the page turning function for the reading app to be removed; the adding is to write a value corresponding to the reading app to be added as true;

step S93, updating the reading app package name list according to the operation of a user;

Step S94, a user opens a reading app and enters a reading page, namely the reading app runs in the foreground;

Step S95, the state control unit reads the packet name of the reading app;

Step S96, the state control unit judges whether the read package name of the reading app is in the package name list of the reading app, when judging that the reading app is in the package name list of the reading app, the step S97 is executed, otherwise, the step S98 is executed;

The state control unit reads the packet name of the reading app, and can parse the packet name string of the current stack top application by reading the current active stack, wherein the recording format is 'complete packet name/complete class name'; the Activity stack refers to a shell command dumpsys ACTIVITY ACTIVITIES provided by an operating system, and stack information of all activities running in the mobile phone is obtained;

step S97, the state control unit opens the state zone bit of the reading app;

Step S98, the state control unit displays a state mark of the reading app as closed;

the method comprises the steps that a user opens an added reading app and opens a reading page of the reading app, the state control unit reads a package name of the reading app, judges that the package name of the reading app is in a list according to a package name list of the reading app, and opens a state zone bit of the reading app;

The user opens the removed reading app, the state control unit reads the package name of the reading app, and according to the list of package names of the reading app, judges that the package name of the reading app is not in the list, and displays the state mark of the reading app as closed.

The event detection unit, see fig. 10, for example, consists of a data source selection module 21, a digital high pass filter 22 and a digital shaping module 23; the event detection unit operates under the condition that the reading app state flag is on, and otherwise, the event detection unit is in a dormant state.

Referring to fig. 11, the implementation and workflow of the event detection unit specifically includes:

Step S301, a user continuously taps the desktop twice, and an acceleration sensor in the mobile phone reports (x, y, z) three-dimensional data values to a data source selection module in the event detection unit;

Step S302, a data source selection module calculates a three-dimensional angle value of the mobile phone to obtain a step S _n, wherein the specific calculation is performed according to the following formula:

g²＝x²+y²+z²

A_x＝arccos(x/g)

A_y＝arccos(y/g)

A_z＝arccos(z/g)

Wherein x, y and z represent acceleration values of the mobile phone containing gravitational acceleration in the three directions, and can also represent orthogonal decomposition of the acceleration values of the mobile phone in the three directions; a _x、A_y、A_z respectively represents included angles between xyz direction and gravity reversal of the mobile phone intrinsic coordinate system; g represents gravitational acceleration;

According to the inherent coordinate system of the mobile phone (see fig. 7), when the mobile phone is erected and the screen is placed on the desktop upwards, see fig. 12a, the x direction is along the screen direction of the mobile phone, from left to right; the y direction is upward along the screen of the mobile phone; the z direction is vertical to the screen of the mobile phone upwards; the x, y and z directions are mutually perpendicular;

When the mobile phone is vertically arranged with the screen upwards placed on the desktop, referring to 12b, the stress F _z =m×a=g=m×g of the mobile phone in the z direction, that is, the acceleration value a in the z direction is equal to the gravity acceleration G, and the stress F _x＝0、F_y =0 of the mobile phone in the x and y directions;

When the mobile phone is vertically arranged on a desktop with the screen upwards and obliquely arranged, referring to fig. 12c, the force F _x =0 of the mobile phone in the x direction, the force F _y =g× sinj =g×cos (90 ° -j) in the y direction, and the force F _z =g× cosj in the z direction, wherein j represents the included angle between the plane of the mobile phone screen and the desktop;

When the mobile phone is placed on the desktop with the screen facing upwards and inclined, referring to fig. 12d, the force F _x =g× sinj =g×cos (90 ° -j) of the mobile phone in the x direction, the force F _y =0 in the y direction, and the force F _z =g× cosj in the z direction, where j represents the angle between the plane of the mobile phone screen and the desktop;

Therefore, when a _z represents the angle j between the plane of the mobile phone screen and the desktop (i.e., j=a _z),A_x represents the angle between the x direction of the mobile phone and the gravity direction, a _x＝90°-j＝arccos(x/g),A_y＝90°-j＝arccos(y/g),A_z =j= arccos (z/g), so as to obtain the above calculation formula;

When A _z is less than or equal to pi/2, z data are selected as input of a digital high-pass filter in the event detection unit, digital high-pass filtering processing is carried out, the z value is recorded as S _n (0 is less than or equal to n, n is an integer and represents the sequence of a data sequence input into the digital high-pass filter, the increment of n is determined by the sampling interval of an acceleration sensor of a mobile phone, and the value of n is increased by 1 when the acceleration sensor reports data once, so that r _n for each subsequent input digital shaping corresponds to a moment), and the fact that the mobile phone screen is upward at the moment, and the included angle between the plane of the mobile phone screen and a desktop is smaller than 45 degrees is indicated;

When A _z is larger than pi/2 and smaller than pi, and when A _y is smaller than pi/2, and the page of the opened reading app in the mobile phone is displayed by a vertical screen, y data is selected as the input of a digital high-pass filter in the event detection unit and recorded as S _n, the mobile phone screen is upward, and the included angle between the plane of the mobile phone screen and the desktop is larger than 45 degrees and smaller than 90 degrees;

When A _z is larger than pi/2 and smaller than pi, and A _x is larger than 3/4 pi or smaller than pi/2, and the page of the opened reading app in the mobile phone is displayed on a horizontal screen, x data is selected as the input of a digital high-pass filter in the event detection unit, and S _n is recorded, so that the mobile phone screen is upward at the moment, and the included angle between the plane of the mobile phone screen and the desktop is larger than 45 degrees and smaller than 90 degrees;

Step S303, performing digital high-pass filtering processing on the S _n calculated in step S302 according to the following formula:

r_n＝P*r_n-1+P*(S_n–S_n-1)

Wherein, P represents the preset filter coefficient, considering that the materials of the desktops on which the mobile phones are placed are different, the users strike the desktops with the same striking force, and the generated vibration frequencies are different, so an interactive interface is provided for the users in the event detection unit, and the users are supported to adjust the values of the parameters according to the needs (for example in the following description); r _n denotes an output of the digital high-pass filter;

the above formula is a differential form of first order high pass filtering, where the parameter P has the following relation to the cut-off frequency f _c of the digital high pass filter and the sampling time interval Δt of the vibration signal:

1/P＝2*π*△t*f_c+1

Wherein Δt depends on the sampling interval of the mobile phone acceleration sensor, and the setting of f _c depends on the material condition of the desktop. Through a digital high-pass filter, the direct current component of the input sequence S _n and the low-frequency component smaller than f _c can be filtered, so that the output r _n fluctuates up and down around a value of 0;

Step S304, the digital shaping module in the event detection unit performs digital shaping processing on the r _n obtained in step S303 (specific processing steps are described in the following steps);

Step S305, judging the threshold value, and checking whether the time difference d between two neighboring taps on the desktop output in step S304 is within a preset minimum value d _min and a maximum value d _max, i.e. the time interval between two consecutive taps by the user should not be smaller than d _min nor larger than d _max; if the number is smaller than d _min, a double-knocking event cannot be distinguished; if the event detection unit is larger than d _max, the event detection unit cannot be regarded as continuous double-knocking events, but is a single-knocking event which occurs in sequence, and when judging that the event of knocking the desktop twice by the user is continuous double-knocking event of knocking the desktop twice, the event detection unit sends a control signal to the page turning control unit.

Referring to fig. 13, the specific operation steps of the digital shaping processing of r _n by the digital shaping module include:

Step S31, two time variables t ₁ and t ₂ are set, and the initial value is set to 0;

Step S32, waiting for the output r _n of the digital high-pass filter, and performing absolute value taking operation on r _n to obtain |r _n |;

Step S33, judging whether |r _n | is larger than V, if yes, carrying out step S34; if the current value is less than V, step S32 is performed;

Step S34, in the duration of the following stable interval T, continuously receiving an |r _n | sequence, monitoring the number of times of |r _n | > V, if the number exceeds M, recording the current time, storing the current time in a variable T ₁, indicating the time when a user first clicks a desktop, and performing step S35; if the current stroke is lower than M, the current stroke is considered to be a noise or invalid stroke, and step S32 is performed;

Step S35, waiting for the output r _n of the digital high-pass filter, and performing absolute value taking operation on r _n to obtain |r _n |;

Step S36, judging whether |r _n | is larger than V, if yes, carrying out step S37; if the current value is less than V, step S35 is performed;

Step S37, in the duration of the following stable interval T, continuously receiving an |r _n | sequence, monitoring the number of times of |r _n | > V, if the number exceeds M, recording the current time, storing the current time in a variable T ₂, indicating the time when a user knocks the desktop for the second time, and performing step S38; if the current stroke is lower than M, the current stroke is considered to be a noise or invalid stroke, and step S32 is performed;

step S38, calculating a time difference d=t ₂–t₁ between two adjacent taps on the desktop, and continuing to perform step S32;

Wherein V represents a preset threshold value for comparing the value of r _n; t represents a preset stabilizing interval, and represents the duration of a single tap; m represents the preset coincidence times, namely, in a stable interval T, when the times of |r _n | > V are larger than or equal to M, an event that a user clicks a desktop is considered to occur; the event detection unit provides a parameter adjustment setting page for a user to adjust preset parameters V, T, M according to the need; the digital shaping module outputs the time difference d between two adjacent strokes of the desktop;

The event detection unit is realized by using an acceleration sensor in the mobile phone, and the method is realized on the basis of the acceleration sensor; the acceleration sensor may also be another sensor, such as a sensor for sensing vibrations. Thus in some embodiments, if a special vibration-sensing sensor is incorporated into the terminal, the value of the vibration-sensing sensor may be directly used to determine if a user double-tap desktop event is a continuous double-tap desktop event.

Referring to fig. 14, the implementation and workflow of the above-mentioned page turning control unit specifically includes:

The page turning control unit simulates the operation effect of clicking or sliding a mobile phone screen by a human hand in a system calling mode;

Step S41, receiving a control signal sent by an event detection unit;

Step S42, starting a sub-thread: when the page turning control unit receives the control signal sent by the event detection unit, the page turning control unit starts a sub-thread;

step S43, creating a java, long, processor, builder object in the sub-thread, wherein the click command or the sliding command is written into a character string array form, and is transmitted into the java, long, processor, builder object as a parameter, and executing the object to realize the page turning operation of the electronic book;

after the sub-thread is started, the main thread of the system page turning service can be prevented from being blocked; creating a process capable of executing shell commands by using the ProcessBuilder objects, wherein the shell commands are command interaction modes provided for users by an operating system;

wherein, the click command character string is in the form of input, tap, x and y, and x and y represent quotation marks, namely character strings;

Wherein the sliding command string is in the form of, for example, "input", "wipe", x ₀、y₀、x₁、y₁, t, wherein x ₀、y₀、x₁、y₁ and t represent quotation marks, i.e. strings;

Wherein x and y represent screen coordinate values to be clicked; x ₀、y₀ represents the initial coordinates of the sliding screen; x ₁、y₁ denotes the screen termination coordinates of the slide; t represents the duration of one slip; the values can be values which are set by a user according to different reading apps, or preset values, and cannot be changed at will by the user;

For most existing book-type apps, clicking the right area of the screen indicates page-backward, clicking the left area of the screen indicates page-forward, clicking the middle area of the screen indicates display of control menu items, etc. Thus, in some embodiments, the screen size is, for example, w×h (width×height), dividing the screen into three parts horizontally and vertically, see fig. 15, then the values of x and y should be in the right part, i.e. 2/3W < x < W,1/3H < y <2/3H; the value of x ₀、x₁、y₀、y₁ should be in the middle region, i.e 1/3W<x₁<x₀<2/3W,x₀-x₁>1/5W,1/3H<y₀＝y₁<2/3H;t＝500ms;

In the above embodiment, the signal that the user continuously taps the desktop event twice is used to represent the backward page turning of the electronic book, and in addition, the signal that the user continuously taps the desktop event three times is used as the backward page turning signal of the electronic book, which is different from the above embodiment, in which the continuous tap event is detected, the backward page turning is that the continuous tap event three times is detected, and the x and y coordinate positions in the clicking command character string need to be modified to be the left part of the screen, that is, 0< x <1/3w,1/3H < y <2/3H.

Referring to fig. 16, the above-mentioned state control unit provides the user with an entry of the interaction page, which may be in the mobile phone setting or in the drop-down shortcut bar; the reading class apps displayed in the interaction page are all from package class names of applications stored in the mobile phone in advance, for example:

<string-array name＝"appNames">

<item>com.chaozh.iReaderFree/com.zhangyue.iReader.read.ui.Activity_BookBrowser_TXT</item>

<item>com.jd.app.reader/com.jingdong.app.reader.main.ui.JdMainActivity</item>

</string-array>

wherein, the front part of the slash "/" in each item is a packet name, and the rear part is a class name;

The interactive page does not display all the prestored applications in a list form in the diagram, and firstly, a program interface provided by a system is used for judging whether the prestored applications are installed on the mobile phone. If the mobile phone is installed on the mobile phone, displaying; if not installed on the mobile phone, the mobile phone is not displayed. Each item in the list has two keys, both of which can only select one; the user selects the application which is removed, the mobile phone does not provide the page turning function for the application, the user selects the application which is added, and the mobile phone provides the page turning function for the application; the mobile phone defaults to support the page turning function for the pre-stored application.

Referring to fig. 17, the event detecting unit provides a parameter adjustment setting page, and the user can slide the adjustment bar to perform parameter setting. The parameter corresponding to the filter parameter adjustment is the P, the parameter corresponding to the threshold adjustment is the V, the parameter corresponding to the stable interval adjustment is the T, and the parameter corresponding to the coincidence times adjustment is the M. Wherein the adjustment range of P is greater than 0 and less than 1.V, T and M are determined according to the mobile phone condition experiment. And the user clicks a default restoration button to restore the default parameters of the mobile phone factory.
