The details will be described below separately.
The embodiment will be described from the perspective of a device for preventing a screen from being touched by mistake, which may be specifically integrated in a terminal, where the terminal may be a terminal with a touch screen, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer).
Referring to fig. 1, fig. 1 is a schematic view of a scene architecture of a screen anti-false touch method according to an embodiment of the present invention. The system comprises a terminal and a server, wherein the terminal and the server are in communication connection through the Internet.
When a user processes through a screen anti-false touch function in the terminal, the terminal can record input and output data in the processing process and then send the recorded data to the server, wherein the terminal can send the data to the server in a WEB mode or can send the data to the server through a client program installed in the terminal.

Referring to fig. 2, fig. 2 is a schematic flow chart of a screen false touch prevention method according to an embodiment of the present invention, where the screen false touch prevention method according to the embodiment includes:
step S101, when detecting that a plurality of touch operations are received on a terminal screen at the same time, determining an application program currently running in a foreground of the terminal.
In an embodiment, detecting that a plurality of touch operations are simultaneously received on the terminal screen can acquire feature information on the terminal screen by setting a preset time interval on the terminal screen, and when a plurality of touch operations simultaneously act on the screen, the terminal acquires the feature information existing on the terminal screen at intervals of the preset time interval and judges whether a plurality of touch operations exist on the terminal screen according to the feature information acquired on the screen.
The characteristic information on the screen may be a current value, a capacitance value, a voltage value, or other characteristic information that may be collected.
Therefore, in the embodiment of the invention, the terminal acquires the capacitance values on the screen at a preset time point, and because the acquired capacitance values are different, whether multiple touch operations exist at the same time is determined according to the acquired capacitance values.
In addition, in the embodiment of the present invention, whether there are multiple touch points may be determined by detecting whether there are multiple operation bodies above the screen within a preset distance from the screen, and determining that there are multiple touch points operating on the screen when there are multiple operation bodies above the screen within a preset distance from the screen.
In order to detect a plurality of operation bodies within a preset distance above a screen, a camera device, an infrared device and/or a microwave touch sensing device may be disposed on the screen of the terminal, and when any one of the camera device, the infrared device and the microwave touch sensing device is turned on, and when any one of the operation bodies approaches a preset sensing range, the terminal acquires corresponding touch information through the started sensing device, and further acquires a signal amplitude value in the touch information, thereby determining the plurality of operation bodies.
And when detecting that a plurality of touch operations are received on the terminal screen at the same time, determining the application program currently running in the foreground of the terminal. In the embodiment of the present invention, a plurality of applications may be simultaneously run in a terminal, some of the applications may run in a foreground (for example, a browser, an electronic book, etc.), and some of the applications may run in a background (for example, a QQ, a WeChat, etc.), and there may be a plurality of methods for determining an application currently running in a foreground of the terminal in this embodiment, for example, all applications currently running in the terminal are acquired, and an application currently running in the foreground is selected from all the applications, that is, a target application. In some embodiments, the terminal may install a plurality of applications, such as a video application, a gaming application, a music application, a photo application, and the like.
Step S102, determining whether the application is a preset application, if not, executing step S103, and if so, ending the process.
In the embodiment of the invention, whether the application program currently operated by the foreground of the terminal is the preset application program is judged. The preset application program may be preset by a developer, and the preset application program may include a plurality of application programs, and the definition of the preset application program is mainly to allow a user to perform operations by multi-touch. For example, the preset application may be a certain game that requires two hands to operate, and the user needs to use multi-touch for operation many times when playing the game.
In the embodiment of the present invention, the preset application program may be stored in the terminal in a list form, and when the terminal determines the application program currently running in the foreground, the application program currently running in the foreground is matched with the preset application program to determine whether the application program is the preset application program.
In an embodiment, the terminal can record the use habits of a user in a historical period, analyze and learn the use habits of the user in the historical period based on machine learning, generate an application program which can be operated by the user through multi-point touch control by the terminal through self-analysis and learning processing procedures to obtain a preset application program database, and automatically judge whether the application program is the preset application program after determining the application program which runs in the foreground of the terminal. For example, the situation that the user uses the terminal in the past month is recorded, and the application program which needs to be operated by using multi-touch in the process of using the terminal by the user is obtained.
Step S103, obtaining a touch trajectory corresponding to each touch operation.
The touch track input by the user can be a touch track of a graph, a touch track of a font, or a touch track of gesture operation; as long as the touch trajectory is continuous. In addition, if the interval between two touch tracks is less than a preset value, the two touch tracks can be regarded as continuous touch tracks.
Wherein, the figure can be round, oval, triangle, rectangle, square, wavy line, etc. Font refers to various characters, such as chinese and english, and numerals. The gesture operation refers to an operation of performing a gesture such as rotation, zoom, and swipe on the screen.
In this embodiment, a user inputs a circle on a touch screen as an example; the method comprises the steps that a user presses a touch screen to start writing a circle to finish writing, the touch screen is lifted up to calculate one continuous circular input, the continuous circular input is captured and used as one user input, and the continuous circular input is converted into input data; thereby completing the acquisition of the circular touch track input by the user on the touch screen.
And step S104, selecting a target track from the plurality of touch tracks, and responding to the target track.
The method for selecting the target track from the plurality of touch tracks may be various, for example, the track lengths of the plurality of touch tracks are respectively obtained, the longest track length is determined as the target track, the target track is responded, and other touch tracks except the target track can be shielded. For example, the target track may be reported, the system may further make a corresponding response, and perform a shielding operation on other touch tracks, and determine that the touch operation corresponding to the touch track is a false operation, at this time, the touch information corresponding to the touch operation may be released, so as to implement a function of preventing the false touch. That is, the step of selecting the target track from the plurality of touch tracks may specifically include:
respectively acquiring the track lengths of a plurality of touch tracks;
and determining the touch track with the longest track length as a target track.
For example, as shown in fig. 3 and 4, when a user performs a one-handed operation on a terminal, the user often performs the operation with a thumb, and as the screen of the terminal is larger, the user is more labored to click certain areas, and meanwhile, due to the narrow frame design of the terminal screen, a wrong operation is more likely to occur, and when the user performs a sliding operation with a thumb of a right hand in the drawing, two touch tracks are generated, namely a touch track S2 corresponding to a fingertip of the thumb and a touch track S1 corresponding to a root of the thumb. At this time, the track lengths of the touch track S2 corresponding to the tip of the thumb and the touch track S1 corresponding to the root of the thumb can be respectively obtained, and the track length of the touch track S2 corresponding to the tip of the thumb is calculated to be longer than the track length of the touch track S1 corresponding to the root of the thumb, so that the touch track S2 corresponding to the tip of the thumb can be determined as a target track and responded to the target track, and meanwhile, the touch operation corresponding to the touch track S1 corresponding to the root of the thumb is determined as an erroneous operation, and the track can be shielded, so that the erroneous touch prevention function can be realized.
As can be seen from the above, the screen false touch prevention method provided in the embodiment of the present invention can determine an application program currently running on a foreground of a terminal when detecting that a plurality of touch operations are simultaneously received on a screen of the terminal, determine whether the application program is a preset application program, if not, obtain a touch trajectory corresponding to each touch operation, select a target trajectory from among a plurality of touch trajectories, and respond to the target trajectory. According to the invention, when the terminal receives the multi-point touch operation, the target track needing to be responded is determined according to different touch tracks and is responded, and the operation corresponding to the touch tracks except the target track is ignored, so that the misoperation of the terminal screen is reduced, and the use accuracy of the terminal is improved.
According to the description of the previous embodiment, the screen anti-false touch method of the present invention will be further explained below.
Referring to fig. 5, fig. 5 is a schematic flow chart of another screen anti-false touch method according to an embodiment of the present invention, including:
step S201, when it is detected that a plurality of touch operations are received on the terminal screen at the same time, determining an application program currently running on the foreground of the terminal.
In an embodiment, detecting that a plurality of touch operations are simultaneously received on the terminal screen can acquire feature information on the terminal screen by setting a preset time interval on the terminal screen, and when a plurality of touch operations simultaneously act on the screen, the terminal acquires the feature information existing on the terminal screen at intervals of the preset time interval and judges whether a plurality of touch operations exist on the terminal screen according to the feature information acquired on the screen.
The characteristic information on the screen may be a current value, a capacitance value, a voltage value, or other characteristic information that may be collected.
Therefore, in the embodiment of the present invention, the terminal acquires the capacitance values on the screen at a preset time point, and since the acquired capacitance values are different, it is determined whether multiple touch operations exist at the same time through the acquired capacitance values, and if so, the application program currently running in the foreground of the terminal is further determined.
Step S202, determining whether the application is a preset application, if not, performing step S203, and if so, ending the process.
In the embodiment of the invention, whether the application program currently operated by the foreground of the terminal is the preset application program is judged. The preset application program may be preset by a developer, and the preset application program may include a plurality of application programs, and the definition of the preset application program is mainly to allow a user to perform operations by multi-touch. The preset application program may be stored in the terminal in a list form, and when the terminal determines the application program currently running in the foreground, the application program currently running in the foreground is matched with the preset application program to determine whether the application program is the preset application program.
Step S203, obtaining a touch trajectory corresponding to each touch operation.
The touch track input by the user can be a touch track of a graph, a touch track of a font, or a touch track of gesture operation; as long as the touch trajectory is continuous. In addition, if the interval between two touch tracks is less than a preset value, the two touch tracks can be regarded as continuous touch tracks.
Step S204, determining whether the touch trajectory is located in the preset touch area, if so, ignoring the touch trajectory, otherwise, executing step S205.
The preset touch area is located in a display area of a terminal screen. Specifically, in this step, the preset touch area may be set as an invalid touch area, and the invalid touch area does not respond to the touch operation, that is, when it is determined that the touch trajectory is located in the invalid touch area, the touch operation is determined as a faulty operation touch, and the function corresponding to the invalid touch area is not triggered.
Specifically, the user may determine, in advance, an area that is frequently touched under the condition of normally operating the touch screen (i.e., under the condition of not operating the touch screen by mistake) and an area that is frequently touched under the condition of operating the touch screen by mistake, and set the area that is frequently touched under the condition of normally operating the touch screen as an effective touch area, and set the area that is frequently touched under the condition of operating the touch screen by mistake as an ineffective touch area, according to actual needs; further, the invalid touch area is set not to respond to the touch operation, that is, when it is determined that the touch point is located in the invalid touch area, the touch is determined as the misoperation touch and the function corresponding to the invalid touch area is not triggered, and when it is determined that the touch point is located in the valid touch area, step S205 is further performed.
If a part of the touch track falls into the preset touch area and a part of the touch track falls into the non-preset touch area, the track lengths of the touch track falling into the preset touch area and the non-preset touch area can be respectively obtained, and then whether the touch track is located in the preset touch area or not is further determined. That is, the step of determining whether the touch trajectory is located in the preset touch area may specifically include:
respectively acquiring a first track length of a touch track falling into a preset touch area and a second track length of the touch track falling into a non-preset touch area;
judging whether the first track length is larger than the second track length;
and if so, determining that the touch track is located in the preset touch area.
Step S205, track lengths of a plurality of touch tracks are respectively obtained.
And step S206, determining the touch track with the longest track length as a target track, and responding to the target track.
After responding to the target trajectory, the method may further include:
determining that the touch operation corresponding to the touch track except the target track is misoperation;
the function corresponding to the misoperation is ignored.
As can be seen from the above, the screen false touch prevention method provided in the embodiment of the present invention may determine, when it is detected that multiple touch operations are simultaneously received on a terminal screen, an application program currently running on a foreground of the terminal, determine whether the application program is a preset application program, if not, obtain a touch trajectory corresponding to each touch operation, determine whether the touch trajectory is located in a preset touch area, if yes, ignore the touch trajectory, if not, obtain trajectory lengths of the multiple touch trajectories, determine that the touch trajectory with the longest trajectory length is a target trajectory, and respond to the target trajectory. According to the invention, when the terminal receives the multi-point touch operation, the target track needing to be responded is determined according to different touch tracks and is responded, and the operation corresponding to the touch tracks except the target track is ignored, so that the misoperation of the terminal screen is reduced, and the use accuracy of the terminal is improved.

The memory 502 may be used to store applications and data. Memory 502 stores applications containing executable code. The application programs may constitute various functional modules. The processor 508 executes various functional applications and data processing by executing application programs stored in the memory 502. The memory 502 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the mobile terminal, and the like.
The input unit 503 may be used to receive input numbers, character information, or user characteristic information (such as a fingerprint), and generate a keyboard, mouse, joystick, optical, or trackball signal input related to user setting and function control. In particular, in one particular embodiment, the input unit 503 may include a touch-sensitive surface as well as other input devices. The touch-sensitive surface, also referred to as a touch display screen or a touch pad, may collect touch operations by a user (e.g., operations by a user on or near the touch-sensitive surface using a finger, a stylus, or any other suitable object or attachment) thereon or nearby, and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface may comprise two parts, a touch detection means and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 508, and can receive and execute commands sent by the processor 508. In addition, touch sensitive surfaces may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves.
