The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The terminal device 100 determines the intensity of the pressure from the change in the capacitance. When a touch operation is applied to the display screen 194, the terminal device 100 detects the intensity of the touch operation based on the pressure sensor 180A. The terminal device 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message. And when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

The proximity light sensor 180G may include, for example, a Light Emitting Diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The terminal device 100 emits infrared light to the outside through the light emitting diode. The terminal device 100 detects infrared reflected light from a nearby object using a photodiode. When sufficient reflected light is detected, it can be determined that there is an object near the terminal device 100. When insufficient reflected light is detected, the terminal device 100 can determine that there is no object near the terminal device 100. The terminal device 100 can utilize the proximity light sensor 180G to detect that the user holds the terminal device 100 close to the ear for talking, so as to automatically turn off the screen to achieve the purpose of saving power. The proximity light sensor 180G may also be used in a holster mode, a pocket mode automatically unlocking and locking the screen.

The ambient light sensor 180L is used to sense the ambient light level. The terminal device 100 may adaptively adjust the brightness of the display screen 194 according to the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust the white balance when taking a picture. The ambient light sensor 180L may also cooperate with the proximity light sensor 180G to detect whether the terminal device 100 is in a pocket, in order to prevent accidental touches.

The fingerprint sensor 180H is used to collect a fingerprint. The terminal device 100 can utilize the collected fingerprint characteristics to realize fingerprint unlocking, access to an application lock, fingerprint photographing, fingerprint incoming call answering and the like.

The touch sensor 180K is also called a "touch device". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on the surface of the terminal device 100, different from the position of the display screen 194.

The keys 190 include a power-on key, a volume key, and the like. The keys 190 may be mechanical keys. Or may be touch keys. The terminal device 100 may receive a key input, and generate a key signal input related to user setting and function control of the terminal device 100.

The motor 191 may generate a vibration cue. The motor 191 may be used for incoming call vibration cues, as well as for touch vibration feedback. For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also respond to different vibration feedback effects for touch operations applied to different areas of the display screen 194. Different application scenes (such as time reminding, receiving information, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

Indicator 192 may be an indicator light that may be used to indicate a state of charge, a change in charge, or a message, missed call, notification, etc.

The SIM card interface 195 is used to connect a SIM card. The SIM card can be brought into and out of contact with the terminal device 100 by being inserted into the SIM card interface 195 or being pulled out of the SIM card interface 195. The terminal device 100 may support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 may support a Nano SIM card, a Micro SIM card, a SIM card, etc. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the plurality of cards may be the same or different. The SIM card interface 195 may also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with external memory cards. The terminal device 100 interacts with the network through the SIM card to implement functions such as communication and data communication. In some embodiments, the terminal device 100 employs eSIM, namely: an embedded SIM card. The eSIM card may be embedded in the terminal device 100 and cannot be separated from the terminal device 100.

The software system of the terminal device 100 may adopt a hierarchical architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes an Android system with a layered architecture as an example, and exemplarily illustrates a software structure of the terminal device 100.

Fig. 2 is a block diagram of a software configuration of the terminal device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc. applications.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide the communication function of the terminal device 100. Such as management of call status (including connection, hangup, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, a prompt tone is given, the terminal device vibrates, an indicator light flickers, and the like.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The following describes exemplary workflow of the software and hardware of the terminal device 100 in connection with capturing a photo scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.

The method for preventing false touch and locking provided by the embodiment of the application will be described in detail below with reference to the accompanying drawings.

The false touch prevention locking method provided by the embodiment of the application is applied to a scene that the terminal equipment is in a screen locking state. The screen locking state can be a screen locking state when the screen is on or a screen locking state when the screen is off. For example, when the terminal device is in a screen-locked state when the terminal device is in a bright screen, the terminal device may enter the interface to be unlocked shown in fig. 3 when detecting a click operation or a touch operation in the display interface. When the terminal device is in a screen locking state during screen turnoff, the terminal device can switch the screen turnoff of the display interface of the terminal device to the screen turnoff when detecting the first click or touch operation in the display interface. Then, when a second click or touch operation in the display interface is detected, the terminal device may enter the interface to be unlocked shown in fig. 3. As shown in fig. 3, a password input box, characters such as numbers and symbols may be displayed in the interface to be unlocked for a user to input a password, and a fingerprint input box may be displayed for a user to input a fingerprint. The terminal equipment can be triggered to unlock according to a password or a fingerprint input by a user in an interface to be unlocked.

The current terminal equipment generally has a locking function, and the locking function enables the terminal equipment to be locked when the terminal equipment detects N times of wrong unlocking operations within preset time, so that a user can not operate the terminal equipment within a certain time, and the safety of the terminal equipment is ensured. The preset time, the N and the certain duration can be respectively determined according to actual conditions. For example, the preset time may be determined as 10 minutes, N may be determined as 5, and the certain time period may be determined as 15 minutes. That is, when the terminal device detects 5 times of wrong unlocking operations within 10 minutes, the terminal device may lock the terminal device for 15 minutes, so that the user may not operate the terminal device within the 15 minutes. The N unlocking operations described below are all N unlocking operations within a preset time.

However, when the existing terminal device detects N times of wrong unlocking operations within the preset time, the locking function of the terminal device is directly started. In actual operation, many wrong unlocking operations are usually not manually and actively input but caused by wrong touch operations, and at this time, if the locking function of the terminal device is directly started, normal use of the terminal device is greatly influenced, and user experience is influenced. Therefore, the embodiment of the application provides a false touch prevention locking method, which can reduce long-time locking of terminal equipment caused by false touch operation, ensure normal use of the terminal equipment and improve user experience.

[ EXAMPLES one ]

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a method for preventing false touch locking according to an embodiment of the present disclosure. The method may be applied to the terminal device shown in fig. 1. As shown in fig. 4, the method for preventing false touch locking may include:

s401, when the terminal device is not unlocked in N times of unlocking operations, obtaining the illumination intensity of the environment where the terminal device is located when the N times of unlocking operations are executed, wherein N is an integer greater than or equal to 1.

In this embodiment, when the terminal device detects N times of incorrect unlocking operations within the preset time, that is, when the terminal device is not unlocked in the N times of unlocking operations, the terminal device may obtain the illumination intensity corresponding to each unlocking operation, so as to determine whether the terminal device is in a pocket or a backpack or the like according to the illumination intensity, thereby determining whether the N times of unlocking operations are incorrect touch operations or not, and whether the locking function of the terminal device needs to be started or not. The illumination intensity corresponding to each unlocking operation refers to the illumination intensity of the environment where the terminal device is located when each unlocking operation is executed.

Specifically, when each unlocking operation is performed, the terminal device may obtain the illumination intensity of the environment where the terminal device is located through an ambient light sensor in the terminal device, and may store the obtained illumination intensity and the current unlocking operation in the terminal device in a correlated manner. Subsequently, the terminal device may directly obtain, from the stored illumination intensity, the illumination intensity of the environment where the terminal device is located when each unlocking operation is performed.

S402, when the illumination intensity is in a preset illumination intensity interval, determining that N times of unlocking operation are mistaken touch operation, and not starting a locking function of the terminal equipment, wherein the illumination intensity interval is constructed according to the illumination intensity corresponding to the mistaken touch operation before the N times of unlocking operation.

In this embodiment, the preset illumination intensity interval may be constructed according to the illumination intensity corresponding to the mis-touch operation in the terminal device unlocking process. Specifically, please refer to fig. 5, where fig. 5 illustrates an application scenario diagram provided in the embodiment of the present application. As shown in fig. 5 (a), when a certain N-time unlocking operation first triggers the locking function of the terminal device, that is, when the locking function of the terminal device is first triggered, the terminal device may display a confirmation window 500 in the interface to be unlocked, may display confirmation information of "whether the N-time unlocking operation is a false touch operation" in the confirmation window 500, and may display a "yes" button 501 and a "no" button 502. When the user clicks or touches the "yes" button 501, the terminal device may determine that the N unlocking operations are mistouch operations, and at this time, the terminal device may not start the locking function of the terminal device, for example, the interface to be unlocked shown in fig. 3 may be continuously displayed for the user to input a password or a fingerprint. Meanwhile, the terminal device can also construct a preset illumination intensity interval according to the illumination intensity corresponding to the N unlocking operations. Subsequently, when the terminal device detects N times of unlocking operations for triggering the locking function of the terminal device again, the terminal device may determine whether the N times of unlocking operations are mistaken touch operations directly according to whether each illumination intensity corresponding to the N times of unlocking operations is in the illumination intensity interval, so as to determine whether the locking function of the terminal device needs to be started. When the user clicks or touches the "no" button 502, it may indicate that the N unlocking operations are manually active input operations, and not mistakenly touching operations, at this time, the terminal device may start the locking function of the terminal device to enter the screen locking interface shown in (b) in fig. 5, where a prompt message "a password is input incorrectly, please try again after waiting for 15 minutes" may be displayed in the screen locking interface.

In one example, when the locking function of the terminal device is triggered for the first time by N times of unlocking operations, the terminal device may start the locking function of the terminal device first, so as to lock the terminal device for a certain period of time, prevent the terminal device from being tried to perform the unlocking operation for multiple times, and ensure the security of the terminal device. Then, the terminal device may display the confirmation window 500 when the terminal device is successfully unlocked, that is, the confirmation window 500 may be displayed in a display interface (e.g., a main interface) after the terminal device is unlocked. In the confirmation window 500, confirmation information of "whether or not the N-time unlocking operation is the false touch operation" may be displayed, and a "yes" button 501 and a "no" button 502 may be displayed. When the user clicks or touches the yes button 501, the terminal device may construct an illumination intensity interval according to the illumination intensity corresponding to the N unlocking operations, so that the display of the confirmation information in the terminal device after the successful unlocking can effectively improve the possibility that the confirmation information is viewed by the user, improve the validity of the confirmation information display, facilitate the accurate determination of the mis-touch operation, and facilitate the construction of an accurate and effective illumination intensity interval.

In another example, to ensure that the constructed illumination intensity interval conforms to the scene requirement changing in real time, the terminal device may periodically perform an update of the illumination intensity interval. Namely, the terminal device can reconstruct the illumination intensity interval every preset time. The preset time period may be determined according to specific situations, for example, the preset time period may be determined to be any value such as 3 days, 5 days, or 10 days. The following is an exemplary description taking the preset time period as 10 days. Therefore, when the lock function of the terminal device is first triggered within the first 10 days, the terminal device may display a confirmation window in which confirmation information of "whether the N unlocking operations are the false touch operations" may be displayed, and a "yes" button and a "no" button may be displayed. When the user clicks or touches the "yes" button, the terminal device may construct an illumination intensity interval according to each illumination intensity corresponding to the N unlocking operations, so that in the first 10 days of subsequent time, the terminal device may directly perform a judgment of a false touch operation according to the illumination intensity interval, thereby determining whether a locking function of the terminal device needs to be started. And when the terminal equipment enters the second 10 days, the terminal equipment can rebuild the illumination intensity interval, namely N times of false touch operations which trigger the locking function of the terminal equipment for the first time in the second 10 days can be obtained again, and the construction of the illumination intensity interval can be rebuilt according to the illumination intensities corresponding to the N times of false touch operations, so that in the subsequent time of the second 10 days, the terminal equipment can directly judge the false touch operations according to the rebuilt illumination intensity interval, and whether the locking function of the terminal equipment needs to be started or not is determined. The third 10 days, the fourth 10 days, the fifth 10 days, and so on, the update of the light intensity interval may be performed with reference to the above.

In this embodiment, the terminal device may calculate a mean μ and a variance σ of the illumination intensity corresponding to the N unlocking operations, and may construct a preset illumination intensity interval according to μ and σ. For example, the terminal device may determine the illumination intensity interval as [ mu-N σ, mu + N σ ].

Therefore, after obtaining the illumination intensity corresponding to a certain N times of unlocking operations, the terminal device may first determine whether the N times of unlocking operations trigger the locking function of the terminal device for the first time. When the N times of unlocking operations do not trigger the locking function of the terminal device for the first time, the terminal device may further determine whether each illumination intensity corresponding to the N times of unlocking operations is within a preset illumination intensity interval. When the illumination intensity corresponding to the N times of unlocking operation is within the illumination intensity interval, the terminal device can determine that the terminal device is in a pocket or a backpack when the N times of unlocking operation is performed, and at the moment, the terminal device can determine that the N times of unlocking operation is mistaken touch operation, that is, the locking function of the terminal device can not be started, so that the user can still normally use the terminal device, and the use experience of the user is improved. When the N unlocking operations are to trigger the locking function of the terminal device for the first time, the terminal device may perform processing of the terminal device and construct the illumination intensity interval according to the foregoing manner.

And S403, when the illumination intensity which is not in the illumination intensity interval exists, determining that the N times of unlocking operation is not error touch operation, and starting the locking function of the terminal equipment.

It can be understood that, when there is an illumination intensity that is not located in the illumination intensity interval in the illumination intensity corresponding to a certain N times of unlocking operations, the terminal device may consider that the N times of unlocking operations are performed, the terminal device may not be in a pocket or a backpack, that is, it may be considered that the N times of unlocking operations may not be a false touch operation, therefore, to ensure the security of the terminal device, the terminal device may directly determine that the N times of unlocking operations are not false touch operations, and start the locking function of the terminal device, so as to lock the terminal device for a certain duration.

In this embodiment, when the terminal device is not unlocked in N times of unlocking operations, the terminal device may obtain the illumination intensity of the environment where the terminal device is located when the N times of unlocking operations are performed. When the illumination intensity is located a preset illumination intensity interval, the terminal device can determine that the N times of unlocking operation is false touch operation, the terminal device can not start the locking function of the terminal device at the moment, and whether the current N times of unlocking operation is false touch operation is determined through the previously constructed illumination intensity interval, so that the determination accuracy of the false touch operation can be effectively improved, long-time locking of the terminal device caused by the false touch operation is reduced, normal use of the terminal device is ensured, and user experience is improved.

It should be noted that the false touch prevention locking method provided by the present embodiment can also be used in combination with the existing pocket mode to improve the accuracy of determining the pocket mode. Specifically, when it is determined that the terminal device is in a pocket or a backpack, i.e., it is determined that the N times of unlocking operations are the false touch operations, according to the false touch prevention locking method provided by the embodiment, the terminal device may start a pocket mode of the terminal device. Or, when the terminal device detects each unlocking operation, the illumination intensity of the environment where the terminal device is located when the unlocking operation is executed may be obtained, and whether the unlocking operation is a false touch operation may be determined according to whether the illumination intensity is within the illumination intensity interval constructed in this embodiment, so as to determine whether the terminal device is currently located in a pocket or a backpack, and thus determine whether a pocket mode of the terminal device needs to be started.

[ example two ]

Referring to fig. 6, fig. 6 is a schematic flowchart illustrating a false touch prevention locking method according to a second embodiment of the present application. The method may be applied to the terminal device shown in fig. 1. As shown in fig. 6, the method for preventing false touch locking may include:

s601, when the terminal device is not unlocked in N times of unlocking operations, obtaining the illumination intensity of the environment where the terminal device is located when the N times of unlocking operations are executed.

S601 is similar to S401 in the first embodiment, and has the same basic principle, and for specific contents, reference may be made to S401 in the first embodiment, and for brevity, details are not repeated herein.

S602, determining whether the illumination intensity is in a preset illumination intensity interval.

And S603, when the illumination intensity is in the illumination intensity interval, acquiring a touch area of a touch point corresponding to the N times of unlocking operations in a display interface of the terminal equipment.

And S604, determining the touch accuracy of the N times of unlocking operations according to the touch area.

It can be understood that, when the terminal device is unlocked by actively inputting a password or a fingerprint by a human, the user generally clicks or touches an area where characters such as numbers or symbols shown in fig. 3 are located, or touches an area where a fingerprint input box is located. Due to uncertainty of the false touch, the probability that the area where the character or the fingerprint is located is clicked or touched every time in the false touch operation is low, that is, the area where the character or the fingerprint input box is located may be accurately clicked or touched by the false touch operation often requiring multiple clicks or touches in the display interface. Therefore, in this embodiment, a preset threshold may be set in advance, where the preset threshold may be the minimum accuracy rate at which the user clicks or touches the character or fingerprint input box in N correct unlocking operations, and thus whether the N unlocking operations are mistaken touch operations may be determined according to the touch accuracy rate corresponding to the N unlocking operations and the preset threshold.

The preset threshold value can be specifically set by the terminal device according to actual conditions, and can also be set by a user in a self-defined manner. For example, the terminal device may set the preset threshold to any one of values such as 0.7 or 0.8 according to the correct unlocking operation of the user history. For example, the user may also set the preset threshold to any value such as 0.6 or 0.75 according to actual conditions.

Specifically, in the process of executing the N times of unlocking operations, the terminal device may obtain a touch area of a touch point in the display interface corresponding to the N times of unlocking operations, and may determine the touch accuracy of the N times of unlocking operations according to the touch area, so that the determination of the false touch operation may be performed according to the touch accuracy. The touch point corresponding to the unlocking operation may include a first touch point clicked or touched to the first preset area, or may include a second touch point clicked or touched to the second preset area. The first preset area is an area where a character or fingerprint input box is located in the display interface, and the second preset area is an area except the area where the character or fingerprint input box is located in the display interface, namely the second preset area is a blank area in the display interface.

In this embodiment, the terminal device may respectively count touch points corresponding to each unlocking operation, and may obtain all touch points corresponding to the N unlocking operations according to the touch points corresponding to each unlocking operation. Or, in order to facilitate statistics of the touch points, in this embodiment, the terminal device may directly determine the statistical time of the touch points as a period of time from a time when the character or fingerprint input box is first clicked or touched to the area where the character or fingerprint input box is located to a time when the N times of unlocking operation recognition ends. That is, the terminal device may start to acquire the first touch point or the second touch point when detecting that the character or the fingerprint input box is clicked or touched for the first time, until the N times of unlocking operation identification is finished, and obtain all touch points corresponding to the N times of unlocking operation.

For example, the terminal device may obtain the number of first touch points and the number of second touch points, and may determine the touch accuracy of the N unlocking operations according to the number of first touch points/(the number of first touch points + the number of second touch points).

For example, in a certain N times of unlocking operations, when the terminal device acquires that the number of first touch points in an area where a character or fingerprint input box is clicked or touched is 21, and the number of second touch points in a blank area in the click or fingerprint input box is 29, the terminal device may determine that the touch accuracy of the N times of unlocking operations is 21/(21+29) ═ 0.42.

And S605, determining whether the touch accuracy is greater than a preset threshold value.

And S606, when the touch accuracy is smaller than or equal to the preset threshold, determining that the N unlocking operations are mistaken touch operations, and not starting the locking function of the terminal equipment.

S607, when the touch accuracy is larger than the preset threshold value or when the illumination intensity which is not in the illumination intensity interval exists, determining that the N times of unlocking operation is not error touch operation, and starting the locking function of the terminal equipment.

For the above S605 and S607, when the touch accuracy of the N times of unlocking operations is less than or equal to the preset threshold, the terminal device may determine that the N times of unlocking operations are not manually and actively input operations, that is, may determine that the N times of unlocking operations are mistouch operations, so as not to start the locking function of the terminal device, so as to facilitate the user to continue to operate the terminal device, and improve the user experience. When the touch accuracy of the N unlocking operations is greater than the preset threshold, the terminal device may determine that the N unlocking operations may be active input operations, and at this time, the terminal device may determine that the N unlocking operations are not false touch operations, and start a locking function of the terminal device to lock the terminal device for a certain duration, so that the user may not perform the operation of the terminal device within the duration.

It can be understood that, when there is an illumination intensity that is not located in an illumination intensity interval in each illumination intensity corresponding to a certain N times of unlocking operations, the terminal device may also consider that the N times of unlocking operations are performed, the terminal device may not be in a pocket or a backpack, that is, it may be considered that the N times of unlocking operations may not be a false touch operation, and at this time, the terminal device may directly determine that the N times of unlocking operations are not false touch operations, and start a locking function of the terminal device.

In this embodiment, when the terminal device is not unlocked in N times of unlocking operations, the terminal device may obtain the illumination intensity of the environment where the terminal device is located when the N times of unlocking operations are performed. When the illumination intensity is within the preset illumination intensity interval, the terminal device may acquire a touch area of a touch point in the display interface corresponding to the N times of unlocking operations, and determine the touch accuracy of the N times of unlocking operations according to the touch area. When the touch accuracy is smaller than or equal to the preset threshold, the terminal device can determine that the N times of unlocking operation is false touch operation, at the moment, the terminal device can not start the locking function of the terminal device, so that the determination of the false touch operation is determined by combining the illumination intensity interval and the touch accuracy, the accuracy of the determination of the false touch operation can be effectively improved, the long-time locking of the terminal device caused by the false touch operation is reduced, the normal use of the terminal device is ensured, and the use experience of a user is improved.

It should be noted that the false touch prevention locking method provided by the present embodiment can also be used in combination with the existing pocket mode to improve the accuracy of determining the pocket mode. Specifically, when it is determined that the terminal device is in a pocket or a backpack, i.e., it is determined that the N times of unlocking operations are the false touch operations, according to the false touch prevention locking method provided by the embodiment, the terminal device may start a pocket mode of the terminal device. Or, when the terminal device detects each unlocking operation, the illumination intensity of the environment where the terminal device is located and the touch area of the touch point corresponding to the unlocking operation in the display interface when the unlocking operation is executed can be acquired, and the touch accuracy of the unlocking operation can be determined according to the touch area, so that whether the unlocking operation is a false touch operation can be determined according to whether the illumination intensity is in the illumination intensity interval constructed in the embodiment and whether the touch accuracy is smaller than or equal to a preset threshold value, and therefore whether the terminal device is currently located in a pocket or a backpack or not is determined, and whether a pocket mode of the terminal device needs to be started or not is determined.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by functions and internal logic of the process, and should not constitute any limitation to the implementation process of the embodiments of the present application.

Fig. 7 shows a block diagram of the structure of the false touch prevention locking device provided in the embodiment of the present application, corresponding to the false touch prevention locking method described in the above embodiment, and only the relevant parts to the embodiment of the present application are shown for convenience of description. The anti-false touch locking device can be applied to terminal equipment.
