Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a terminal management method and terminal device. Background Technology

[0002] With the development of technology, terminal devices can offer an increasing number of services. Taking mobile phones as an example, they can provide not only traditional calling services but also various other life services such as payment, entertainment, work, and study. Of course, while providing convenience, mobile phones also pose significant risks to users with lower self-control (such as children), such as addiction to mobile games and being misled into making purchases.

[0003] Most children do not own their own mobile phones. When children need to use a phone, they can borrow their parents' phones. To control children's phone use, parents need to manually manage the phone before lending it out, such as setting app usage time limits and hiding apps that might affect the child. Obviously, the human-computer interaction efficiency of this process is extremely low. Furthermore, it becomes even more difficult for parents to manage when children borrow multiple devices in succession. Summary of the Invention

[0004] This application provides a terminal management method and terminal device to improve the efficiency of human-computer interaction in controlling children's use of terminal devices.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a terminal management method applied to a terminal system; the terminal system includes a first device and a second device, the method comprising: the first device sending first information to the second device; wherein the first information includes a first duration; the first duration is the cumulative running time of a first application while a first child is using the first device; after the second device is unlocked, the second device displays a first interface and collects a first biometric feature; wherein the first interface includes a first icon; the first icon is the application icon of the first application; the first biometric feature includes at least one of a user's facial features, iris features, fingerprint features, and voiceprint features; when the first biometric feature indicates that the first child is using the first icon, if the second device receives an operation on the first icon, then if the first duration is not less than a first time value, the second device displays an application lock interface, or does not respond to the operation on the first icon; the application lock interface is used to prompt the user that the first application is in a disabled state; the first time value is a preset time limit for the first child to use the first application.

[0007] In this context, the first device and the second device can be mutually authenticated terminal devices, and can be considered to belong to the same terminal system. For example, the first device and the second device can be mobile phones belonging to different family members in a home setting. Furthermore, the first device and the second device can also be different types of terminal devices in a home setting, such as a mobile phone and a tablet computer.

[0008] Furthermore, there are synchronization restrictions between the first device and the second device for the first child, such as application usage restrictions and terminal usage restrictions. The application usage restrictions include limiting the duration of the first child's use of certain applications; for example, limiting the duration of the first child's use of a specific application. When the first child's limited usage time for an application is zero, the first child is instructed to disable the application. When the first child's limited usage time for an application is not zero, the first child is instructed to have a limit on the cumulative time spent using the application. Therefore, the aforementioned first application is an application with usage restrictions.

[0009] In the above embodiments, the first device can notify the second device of the cumulative runtime of the first application during the first child's use of the first device, i.e., the first duration. Thus, after the second device is unlocked, if the phone identifies the user as the first child, it can first determine whether the first duration exceeds the first child's restricted usage time for the first application. If the first duration is not less than the first child's restricted usage time for the first application, the second device will prevent the first child from disabling the first application. This effectively controls children from circumventing terminal usage restrictions by changing their devices. For parents, this control is not only efficient but also requires no complex configuration, improving the human-computer interaction efficiency of managing children's phone use.

[0010] In some possible embodiments, before the first device sends the first information to the second device, the method further includes: the first device unlocking; the first device displaying a second interface and collecting a second biometric feature; wherein the second interface includes the first icon; the second biometric feature includes at least one of the user's facial features, iris features, fingerprint features, and voiceprint features; if the second biometric feature indicates the first child, and the second device receives an operation on the first icon, the first device displays the application interface of the first application and obtains the first duration; the first device sending the first information to the second device includes: after the first device closes the first application or the first device locks its screen, the first device sends the first information to the second device.

[0011] In the above embodiments, when the first device does not receive the third duration and the first time value is not zero, the first device can respond to the user's instruction to run the first application and normally display the application interface of the first application. The third duration is the cumulative runtime of the first application while the first child is using other terminals. For example, the third duration could also be the second duration sent by the second device.

[0012] Of course, during the display of the first application, the first device can accumulate the first child's first usage time of the first application. In this way, after the first device closes the first application or unlocks the first device, the first device can notify other terminals of the first child's usage time of the first application.

[0013] In some possible embodiments, during the period when the first device acquires the first duration, the method further includes: if the first duration exceeds the first time value, the first device displays a first prompt window; the first prompt window is used to prompt the user that the first application is disabled.

[0014] In the above embodiments, if the first device exceeds the limit for the cumulative usage time of the first application, it will also promptly remind the user to pause the use, thereby controlling the use of the device by children.

[0015] In some possible embodiments, if the second device receives an operation on the first icon when the first biometric indicates the first child, the method further includes: if the first duration is less than the first time value, the second device displays the application interface of the first application and obtains a second duration; wherein the second duration is the cumulative running time of the first application while the first child uses the second device; if the sum of the first duration and the second duration exceeds the first time value, the second device displays a first prompt window; the first prompt window is used to prompt the user that the first application is in a disabled state.

[0016] In the above embodiments, if the time the first child uses the first application on the first device does not exceed the first time value, the first child can continue to use the first application on the second device, but the available time will be shortened, thereby more accurately controlling the child's use of the device and improving control efficiency.

[0017] In some possible embodiments, when the first biometric indicates the first child, the method further includes: the second device detecting a first distance between the user's eyes and the display screen of the second device; if the first distance is less than a preset distance value, the second device displaying a second prompt window; the second prompt window is used to prompt the user to adjust the distance between their eyes and the display screen of the second device.

[0018] In the above embodiments, the second device can also control the human-machine distance between the first child and the display screen. When the distance is too close, the device will promptly remind the first child to avoid affecting their eyesight.

[0019] In some possible embodiments, when the first biometric indicates the first child, the method further includes: the second device detecting ambient light intensity; when the detected ambient light intensity is lower than a preset light threshold, the second device displaying a third prompt window; the third prompt window is used to prompt the user to pause the use of the second device.

[0020] In the above embodiments, the second device can also control the lighting environment of the device. When the ambient light intensity is poor, it can promptly remind the first child to avoid affecting the child's eyesight.

[0021] In some possible embodiments, if the second device receives an operation on the first icon when the first biometric indicates the first child, the method further includes: if the first duration is less than the first time value, the second device displays the application interface of the first application; if the second prompt window or the third prompt window appears in the application interface of the first application, the second device pauses the output of the application services provided by the first application.

[0022] In the above embodiments, in addition to reminding the first child to pay attention to the distance between the person and the device and the lighting environment, the second device will also restrict the first child from continuing to use the second device when the distance between the person and the device is too close or the lighting environment is poor, thus effectively controlling and protecting the first child.

[0024] In the above embodiments, the second device dynamically adjusts the frequency of facial feature collection to ensure that it can identify whether the user has changed in real time, or determine the human-machine distance between the user and the display screen in real time, while maintaining low power consumption, thereby achieving precise control.

[0025] In some possible embodiments, after collecting the first biometric feature, the method further includes: when the first biometric feature indicates that the user includes both the first child and the second child, the second device determines a third restriction condition based on a first restriction condition and a second restriction condition; wherein the first restriction condition is an application usage restriction set for the first child; the second restriction condition is an application usage restriction set for the second child; if the second device receives an operation on the first icon, then if the first duration is not less than a second time value, the second device displays an application lock interface, or does not respond to the operation on the first icon; wherein the second time value is the duration for which the third restriction condition indicates that the first application is restricted.

[0026] In the above embodiments, when the second device is dealing with multiple children, in order to ensure that each child is within the control range, the second device can integrate the restrictions for multiple children to obtain the actual operating restrictions, thereby achieving effective control over multiple people.

[0069] The implementation of this embodiment will now be described in detail with reference to the accompanying drawings.

[0070] As the operability of terminal devices improves, the user base is no longer limited by age. However, users lacking self-control and with low cognitive abilities (such as children) require effective supervision during their use of these devices. Furthermore, children typically do not own their own devices and frequently borrow others'. During this borrowing process, the device owner also needs to assume responsibility for supervising the child's use of the device.

[0071] Therefore, this application provides a terminal management method applicable to the use of a terminal device. The terminal device includes a display screen and a camera. After the terminal device is unlocked, it can determine whether a child is watching the display screen via the camera. If a child is detected watching the display screen, the terminal device activates a child control mode. During the activation of child control mode, at least one application on the terminal device is subject to usage restrictions, such as being prohibited from use or having its usage time limited. If no child is detected watching the display screen, the terminal device activates normal mode. During the period of activation of normal mode, applications on the terminal device are not subject to the usage restrictions corresponding to the child control mode.

[0072] In this way, while strengthening the control over children's use of mobile phones, it does not affect the normal use by non-child users (such as the phone owner), thus improving the human-computer interaction efficiency of terminal devices.

[0073] Taking a mobile phone as an example, such as Figure 1 As shown, after the phone unlocks, it captures image information in real time via its camera. It then analyzes the images showing faces to determine if children are among the users looking at the display. It's important to note that this camera can be the phone's front-facing camera to accurately detect whether a child is looking at the screen.

[0074] When it is determined that a child is among the users looking at the display screen, the phone activates child control mode. When it is determined that no child is among the users looking at the display screen, the phone operates in normal mode. The phone can flexibly switch between child control mode and normal mode based on the user's behavior. This restricts children's use of the phone without affecting the normal use of the phone by non-child users.

[0075] Additionally, while the phone is running in normal mode, it can also receive instructions to activate child control mode and respond to these instructions to activate child control mode. In this way, the phone can not only flexibly switch between child control mode and normal mode depending on the user looking at the screen, but can also directly enter child control mode based on the user's instructions.

[0076] It should be noted that the children mentioned in the above embodiments are a type of user who needs to be managed while using the terminal device. When the user of the terminal device is another user who needs to be managed, the above terminal management method can also be used for management, and this application embodiment does not limit this.

[0077] For example, the aforementioned terminal device can also be a tablet computer, handheld computer, PC, cellular phone, personal digital assistant (PDA), wearable device (such as a smartwatch), in-vehicle computer, game console, and augmented reality (AR) / virtual reality (VR) device, etc. This embodiment does not impose any special limitations on the specific form of the terminal device. In addition, the technical solution provided in this embodiment can be applied not only to the aforementioned terminal devices (or mobile terminals), but also to other terminal devices, such as smart home devices (such as televisions), etc.

[0078] The following section continues using a mobile phone as an example to introduce the hardware structure of terminal devices.

[0079] Please refer to Figure 2 Terminal devices (such as mobile phones) may include: processor 210, external memory interface 220, internal memory 221, universal serial bus (USB) interface 230, charging management module 240, power management module 241, battery 242, antenna 1, antenna 2, mobile communication module 250, wireless communication module 260, audio module 270, speaker 270A, receiver 270B, microphone 270C, headphone jack 270D, sensor module 280, buttons 290, motor 291, indicator 292, camera 293, display screen 294, and subscriber identification module (SIM) card interface 295, etc.

[0080] The aforementioned sensor module 280 may include sensors such as pressure sensors, gyroscope sensors, barometric pressure sensors, magnetic sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, touch sensors, ambient light sensors, and bone conduction sensors.

[0081] It is understood that the structure illustrated in this embodiment does not constitute a specific limitation on the mobile phone. In other embodiments, the mobile phone may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0082] Processor 210 may include one or more processing units, such as application processor (AP), modem processor, graphics processing unit (GPU), image signal processor (ISP), controller, memory, video codec, digital signal processor (DSP), baseband processor, and / or neural network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors.

[0083] The controller can be the nerve center and command center of a mobile phone. Based on the instruction opcode and timing signals, the controller generates operation control signals to control the fetching and execution of instructions.

[0084] The processor 210 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 210 is a cache memory. This memory can store instructions or data that the processor 210 has just used or that are used repeatedly. If the processor 210 needs to use the instruction or data again, it can directly retrieve it from the memory. This avoids repeated accesses, reduces the waiting time of the processor 210, and thus improves the efficiency of the system.

[0085] In some embodiments, the processor 210 may include one or more interfaces. Interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0086] It is understood that the interface connection relationships between the modules illustrated in this embodiment are merely illustrative and do not constitute a structural limitation on the mobile phone. In other embodiments, the mobile phone may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0087] The charging management module 240 receives charging input from a charger, which can be a wireless charger or a wired charger. While charging the battery 242, the charging management module 240 can also supply power to the mobile phone via the power management module 241.

[0088] The power management module 241 connects the battery 242, the charging management module 240, and the processor 210. The power management module 241 receives input from the battery 242 and / or the charging management module 240, and supplies power to the processor 210, internal memory 221, external memory, display 294, camera 293, and wireless communication module 260, etc. In some embodiments, the power management module 241 and the charging management module 240 may also be housed in the same device.

[0089] The wireless communication function of a mobile phone can be implemented through antenna 1, antenna 2, mobile communication module 250, wireless communication module 260, modem processor, and baseband processor. In some embodiments, antenna 1 and mobile communication module 250 are coupled, and antenna 2 and wireless communication module 260 are coupled, enabling the mobile phone to communicate with networks and other devices, such as wearable devices, through wireless communication technology.

[0090] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in the mobile phone can be used to cover one or more communication frequency bands. Different antennas can also be reused to improve antenna utilization. For example, antenna 1 can be reused as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with a tuning switch.

[0091] The mobile communication module 250 can provide solutions for wireless communication applications in mobile phones, including 2G / 3G / 4G / 5G. The mobile communication module 250 may include at least one filter, switch, power amplifier, low-noise amplifier (LNA), etc. The mobile communication module 250 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation.

[0092] The mobile communication module 250 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via the antenna 1. In some embodiments, at least some functional modules of the mobile communication module 250 can be housed in the processor 210. In some embodiments, at least some functional modules of the mobile communication module 250 and at least some modules of the processor 210 can be housed in the same device.

[0093] The wireless communication module 260 can provide solutions for wireless communication applications in mobile phones, including WLAN (such as wireless fidelity, Wi-Fi), Bluetooth, Global Navigation Satellite System (GNSS), frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies.

[0094] GNSS can include the BeiDou Navigation Satellite System (BDS), the Global Positioning System (GPS), the Global Navigation Satellite System (GLONASS), the Quasi-Zenith Satellite System (QZSS), and / or satellite-based augmentation systems (SBAS).

[0095] The wireless communication module 260 can be one or more devices integrating at least one communication processing module. The wireless communication module 260 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signal, and sends the processed signal to processor 210. The wireless communication module 260 can also receive signals to be transmitted from processor 210, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0096] The mobile phone implements its display function through a GPU, a display screen 294, and an application processor. The GPU is a microprocessor for image processing, connected to the display screen 294 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. The processor 210 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0097] The display screen 294 is used to display images, videos, etc. The display screen 294 includes a display panel.

[0098] The mobile phone can perform shooting functions through an ISP, camera 293, video codec, GPU, display 294, and application processor. The ISP is used to process the data fed back by the camera 293. The camera 293 is used to capture still images or videos. In some embodiments, the mobile phone may include one or N cameras 293, where N is a positive integer greater than 1.

[0099] The external storage interface 220 can be used to connect an external storage card, such as a Micro SD card, to expand the phone's storage capacity. The external storage card communicates with the processor 210 through the external storage interface 220 to perform data storage functions. For example, music, video, and other files can be saved on the external storage card.

[0100] Internal memory 221 can be used to store computer executable program code, which includes instructions. Processor 210 executes various functions and applications of the mobile phone and performs data processing by running the instructions stored in internal memory 221. For example, in this embodiment, processor 210 can execute instructions stored in internal memory 221, which may include a program storage area and a data storage area.

[0101] The program storage area can store the operating system, at least one application required for a function (such as sound playback, image playback, etc.). The data storage area can store data created during the use of the phone (such as audio data, phonebook, etc.). Furthermore, the internal memory 221 can include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc.

[0102] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the mobile phone. In other embodiments of this application, the mobile phone may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0103] The terminal management method provided in this application can be implemented in a device with the above hardware structure. The following description continues to use a mobile phone as the terminal device and, in conjunction with the accompanying drawings, details the implementation methods of this application.

[0104] like Figure 3 As shown, the terminal management method provided in this application includes the following steps:

[0105] S101, the phone unlocks based on the user's actions.

[0106] For example, the phone can be unlocked with a password. That is, the phone can receive a password entered by the user, and if the received password is verified, an unlock screen including a door curtain is displayed. Conversely, if the received password fails verification, the phone remains locked.

[0107] As another example, the phone can also be unlocked via fingerprint. That is, the phone's fingerprint sensor can collect the user's fingerprint information. Once the phone collects the fingerprint information and it passes verification, an unlock screen including a door curtain is displayed. If the phone collects the fingerprint information but it fails verification, the phone remains locked.

[0108] As another example, a mobile phone can also be unlocked via facial recognition. That is, the phone's camera can capture image information containing a face. After capturing the image information containing a face, the phone can extract the facial information. If the extracted facial information passes verification, the phone displays an unlock screen including a door curtain. Conversely, if the extracted facial information fails verification, the phone remains locked.

[0109] In some embodiments, the phone has a default mode, which can be either a child control mode or a normal mode. Thus, after the phone is unlocked, the default mode is activated first.

[0110] In other embodiments, after the phone screen is locked, the operating mode before locking can be recorded. When the phone is unlocked again, the recorded operating mode is used first. For example, if the phone was running in normal mode before locking, then the recorded operating mode after locking is normal mode. Thus, when the phone is unlocked again, normal mode can be used first. As another example, if the phone was running in parental control mode before locking, then the recorded operating mode after locking is parental control mode. Thus, when the phone is unlocked again, parental control mode can be used first.

[0111] Of course, the actual operating mode can also change dynamically after the phone is unlocked.

[0112] In some embodiments, after the phone is unlocked, the operating mode of the phone can be dynamically changed by analyzing whether the user looking at the display screen is a child.

[0113] S102: After the phone is unlocked, it can determine in real time whether the current user is a child.

[0114] In some embodiments, the mobile phone can use a front-facing camera to capture image information. When the user is looking at the phone's display screen, the front-facing camera can capture image information including a facial image. At this time, the phone can determine whether the corresponding user is a child by analyzing the image information.

[0115] One implementation method involves using a pre-trained age recognition model to classify the collected image information. Through this classification, the mobile phone can determine whether an image contains a face and, moreover, the age range corresponding to that face. Thus, when a face appears in an image, the mobile phone can determine whether the user indicated by the face is a child. The age recognition model can be a deep learning model. The training process for this model can be found in relevant technologies and will not be elaborated upon here.

[0116] As another implementation method, after the mobile phone captures image information, it can extract facial features based on that image information. When the mobile phone extracts facial features, the following situations may occur: First, the image information does not contain a face image, and the mobile phone cannot extract facial features. Second, the image information contains a face image, but the mobile phone fails to extract facial features. Third, the image information contains a face image, and the mobile phone successfully extracts facial features from the image information.

[0117] When the mobile phone extracts facial features from the image information, such as facial feature 2, it can compare facial feature 2 with preset facial unlock features. These facial unlock features represent users with unlocking privileges. Each facial unlock feature corresponds to a user identifier, which indicates the identity of the user associated with the facial unlock feature. For example, the user identifier may include a phone owner identifier, indicating that the corresponding user is the actual owner of the phone.

[0118] When facial feature 2 matches the facial unlock feature corresponding to the owner's identifier in the unlock feature list, it is determined that the user indicated by the facial image in the image information is not a child. When facial feature 2 does not match the facial unlock feature corresponding to the owner's identifier, an age recognition model is used to identify whether the user indicated by the facial image in the image information is a child. This improves the problem of young-looking owners being mistakenly affected by child control modes.

[0119] In the above embodiments, the user's face is used to determine whether the user is a child. In other possible embodiments, the user's biological characteristics can also be used to determine whether the user is a child. For example, identification can be based on voiceprint features.

[0120] As another implementation, the mobile phone can also include the biometrics of at least one designated child. For example, facial features, fingerprint features, iris features, voiceprint features, etc. Any type of biometric feature can identify the child user. In this way, the mobile phone can determine whether the user is a child by collecting the user's biometrics in real time and then comparing the user's biometrics with the biometrics of the designated child. In subsequent embodiments, the description will primarily focus on the mobile phone including the facial features of the designated child, such as referred to as facial feature 3. Furthermore, the process of configuring the facial features of the designated child can be detailed in subsequent embodiments.

[0121] For example, when a mobile phone includes the facial features of at least one designated child, the phone can use its front-facing camera to capture image information. Then, facial features are extracted based on the captured image information. If the phone extracts facial feature 2 based on the image information, it compares facial feature 2 with facial feature 3. If facial feature 2 and facial feature 3 match, the phone determines that the current user is a child. If facial feature 2 and facial feature 3 do not match, the phone determines that the current user is not a child.

[0122] As another implementation, when the phone uses facial recognition to unlock, it can retain the facial feature 1 used to unlock the phone. The phone can then use its front-facing camera to capture image information. If the phone recognizes a face in the image, it extracts facial feature 2 from that image. The phone can then compare facial feature 2 with facial feature 1. If they match, the phone determines that the current user is not a child. If they do not match, the phone determines that the current user is a child, or it can use an age recognition model to further determine if the user is a child. In this way, when the phone has multiple facial unlock features with the owner's identifier, the number of comparisons can be reduced.

[0123] Regardless of the implementation method used, in order to promptly identify user changes—such as whether a user has changed from a non-child user to a child user, or vice versa—the mobile phone needs to periodically collect image information. In some examples, the aforementioned period can be a regular time period. In other examples, the aforementioned period can be an irregular time period. This application does not impose specific limitations on this aspect.

[0124] Furthermore, for each frame of image information captured, the phone can perform facial feature extraction once. It is evident that the frequency with which the phone's front-facing camera captures image information is consistent with the frequency with which the phone performs facial feature extraction. For ease of description, "capturing one frame of image information and performing one facial feature extraction" can be referred to as one facial feature capture.

[0125] In some embodiments, facial feature acquisition begins after the user interface displayed on the phone switches from the unlock screen to the desktop (e.g., the first screen). Additionally, the phone may employ a low-power strategy for facial feature acquisition.

[0126] For example, during the process of acquiring facial features using a low-power strategy, the mobile phone can dynamically adjust the acquisition frequency of facial features. This effectively reduces the energy consumption of acquiring facial features.

[0127] For example, such as Figure 4 As shown, when the phone is locked, it does not collect facial features; that is, the frequency of facial feature collection is 0fps. After the phone unlocks and displays the desktop, it can collect facial features at a set frequency 1, also known as the first frequency (e.g., 5fps), and use the collected facial features as facial feature 2. After collecting facial feature 2, the phone can also analyze whether the user indicated by facial feature 2 is a child. The specific analysis process can be referred to in the aforementioned embodiments and will not be repeated here. In addition, it should be noted that after determining whether the user is a child, it is still necessary to continue collecting facial features. On the one hand, this can monitor whether the user changes, such as whether they change from a non-child to a child, or whether they change from child 1 to child 2. On the other hand, it can also be used to determine the human-machine distance between the user and the phone in real time. The use of the obtained human-machine distance will be described in detail in subsequent embodiments and will not be repeated here.

[0128] Therefore, after determining whether the user indicated by facial feature 2 is a child, the mobile phone can reduce the frequency of facial feature collection to frequency 2, such as the second frequency (e.g., 1fps). That is, the mobile phone continues to collect facial features at a lower frequency, which not only monitors changes in the user but also reduces the phone's power consumption.

[0129] Subsequently, if the phone detects the disappearance of a face, for example, if the phone determines that there is no face image in the collected image information, the phone continues to collect facial features at frequency 2. Of course, in some other possible embodiments, the phone may temporarily increase the collection frequency to frequency 1 after detecting the disappearance of a face.

[0130] For example, a phone has a preset time period t. If the phone detects a face disappearing, it continues to collect facial features at frequency 1 for the remaining time t. If the face reappears within time t, the phone acquires facial feature 2 again and analyzes it to determine if the user is a child. After determining that the user indicated by facial feature 2 is a child, the phone lowers the facial feature collection frequency back to frequency 2.

[0131] For example, a phone may have a preset time period 't'. If the phone detects a face disappearing, it continues to collect facial features at frequency 1 for the duration 't' after the face disappears. If no face is detected within 't', the phone lowers the facial feature collection frequency to frequency 2. If the phone then detects a face again, it can raise the facial feature collection frequency back to frequency 1. Thus, after obtaining facial feature 2 again and determining whether the user indicated by facial feature 2 is a child, the phone can lower the facial feature collection frequency back to frequency 2.

[0132] In addition, when the phone displays other user interfaces, such as during application interfaces or when the phone switches between different user interfaces, the phone can still collect facial features according to the low-power strategy described above. The principle is similar to that in the examples above, and will not be repeated here.

[0133] Thus, each time the phone collects facial features, it can determine whether the current user is a child, or whether the user is a designated child. After determining that the user is a child or a designated child, the process proceeds to S103. If it is determined that the user is not a child, the phone switches to normal mode. While in normal mode, the phone continues to collect facial features and determines whether the user has become a child based on the collected facial features. After determining that the user has become a child, the process proceeds to S103.

[0134] In other embodiments, after the phone is unlocked, a conscious user authentication can be performed to determine whether the user is a child or not. For example, after unlocking the phone, an authentication interface can be displayed, prompting the user to cooperate in collecting at least one biometric feature, such as facial features, iris features, fingerprint features, and voiceprint features. The phone then determines whether the user is a child based on the collected biometric features. If the user is not a child, the normal mode is activated. Alternatively, if the user is a child, the process proceeds to S103.

[0135] S103: When the user is identified as a child, the phone activates the corresponding child management mode.

[0136] In some embodiments, the mobile phone can enable a general child management mode. This general child management mode may include usage restrictions on at least one application, such as limiting the application's available time or restricting its activation. The restricted application in the general child management mode can be a default application. Additionally, the general child management mode may also include restrictions on the device's (i.e., the mobile phone's) usage status, such as viewing distance control, attention control, and ambient light control during phone use. Similarly, the device usage status restrictions in the general child management mode can also be default.

[0137] In some embodiments, when child management mode is enabled, the phone can control applications according to usage restrictions. For example, a payment app may be a restricted application. When the phone receives an instruction to enable the payment app, it will not respond to that instruction. As another example, a video app may be a video app with a 2-hour usage limit. If the total time the phone displays the video app's interface exceeds 2 hours, the phone will stop providing the video app's services to the user.

[0138] In some embodiments, after enabling child management mode, the phone can also restrict user usage based on the device's usage status. For example, if the phone is too close to the user, the user may be restricted from using the phone. Or, if the ambient lighting conditions are unsuitable, the user may be restricted from using the phone.

[0139] Additionally, in child control mode, the phone can also force users to take a break. For example, child control mode includes a single usage time limit. In child control mode, the phone starts timing from unlocking and ends when the screen locks. During the timing period, if the time exceeds the single usage time limit, the phone can prompt the user to take a break. Of course, after prompting the user to take a break, the phone can also restrict the user's continued use, such as forcing the screen to turn off for a specified time or disabling services currently provided by the phone. In some cases, the corresponding single usage time can be different for children of different age groups. For example, the single usage time for designated children aged 4-12 could be 1 hour, and the single usage time for designated children aged 13-16 could be 2 hours.

[0140] In other embodiments, when the user is identified as a designated child, the mobile phone can enable a child management mode corresponding to that child. This child management mode may also include usage restrictions on at least one application. The applications restricted by this child management mode can be set by the user. Additionally, the child management mode may also include restrictions on device usage status. Similarly, these device usage status restrictions in the child management mode can also be configured by the user.

[0141] As can be seen, in some embodiments, the mobile phone can also respond to user operations and determine the child management mode corresponding to a specific child.

[0142] For example, such as Figure 5 As shown in (a), the mobile phone's desktop 501 includes a control 502 for configuring system functions. When the mobile phone receives an operation from the user on the control 502, it can display as shown in (a). Figure 5Interface 503 is shown in (b) above. Interface 503 lists configurable system functions, such as function 504 indicating child control configuration.

[0143] When the above interface 503 includes a large number of system function items, some system function items may be hidden.

[0144] In some examples, the phone can receive a user's swipe gesture on interface 503 to toggle the display of hidden system functions, making it easier for the user to find the desired system function. In other examples, the phone can also receive information 1 entered by the user in search window 505. This information 1 can be used to indicate at least one system function; for example, information 1 can be a keyword for a system function. Thus, the phone can search for and display the system function corresponding to information 1. For example, if the phone receives information 1 (child) entered by the user in search window 505, it can search for and display function 504 indicating child management configuration.

[0145] In some embodiments, the mobile phone may also display a corresponding parameter configuration interface based on the user's operation on a system function. For example, when the mobile phone receives a user's operation on function 504, such as clicking the operation, the mobile phone displays the following: Figure 5 Interface 506 is shown in (c). Interface 506 includes an information card corresponding to a specified child, such as card 507. Card 507 is used to display the basic information of the specified child. For example, the basic information includes the specified child's portrait information. The mobile phone can extract the corresponding facial features 3 from this portrait information.

[0146] As another example, the basic information mentioned above may also include the child's age information and child identifier (e.g., Da Bao). The child identifier can be used to indicate the user corresponding to facial feature 3.

[0147] As another example, the aforementioned basic information may also include the child's iris features, fingerprint features, and voiceprint features.

[0148] Additionally, interface 506 includes several application permission configuration items, such as application restriction controls, application quota controls, and disabling time controls. The phone can determine which applications are enabled and disabled in the "DaBao" child control mode based on the user's actions with the application restriction controls. The phone can also determine the available time for applications in the "DaBao" child control mode based on the user's actions with the application quota controls. Furthermore, the phone can determine the disabled periods for each application in the "DaBao" child control mode based on the user's actions with the disabling time controls.

[0149] In some embodiments, Figure 6As shown in (a), when a user clicks the application restriction control in interface 506, the phone receives the user's action on the application restriction control. Then, the phone responds to this action by displaying... Figure 6 The interface 601 shown in (b) above. The interface 601 includes multiple application identifiers, which can be used to indicate the applications installed on the mobile phone. For example, the application identifier can be an application name or an application icon.

[0150] Interface 601 also includes a status flag corresponding to the application identifier. This status flag indicates whether the application corresponding to the application identifier can be enabled. The status flag can include "prohibited," "enabled," and "not configured." When the status flag is "prohibited," it indicates that the corresponding application cannot be enabled. When the status flag is "enabled" or "not configured," it indicates that the corresponding application can be enabled.

[0151] Of course, users can configure or change the status flags of individual applications. In some embodiments, the phone can receive a user's selection of a status flag. Then, in response to the selection, the phone displays a corresponding status change window. This status change window includes option 1, indicating that the application is prohibited, and option 2, indicating that the application is allowed. The phone can receive the user's action on option 1 or option 2 and determine the changed status flag accordingly. For example, if the selected status flag is "prohibited," option 1 in the status change window is selected. If the phone receives a user's action on option 2, it can determine to change the status flag to "allowed." Similarly, if the selected status flag is "allowed," option 2 in the status change window is selected. If the phone receives a user's action on option 1, it can determine to change the status flag to "prohibited." Furthermore, if the selected status flag is "not configured," both option 1 and option 2 in the status change window are unselected. If an action is received on option 1, it can determine to change the status flag to "prohibited." If an action is received on option 2, it can determine to change the status flag to "allowed."

[0152] As can be seen, users can independently determine the status flags corresponding to different applications through operations in interface 601. In this way, in the child control mode corresponding to "Dabao", the phone can restrict the access permissions of each application according to its status flag.

[0153] For example, such as Figure 7 As shown in (a), the mobile phone determines the current user as a designated child, such as Da Bao, based on the collected facial feature 2. The mobile phone can then enable the child control mode corresponding to Da Bao. Figure 6As shown in (b) above, the payment app is marked as disabled. When the phone is in parental control mode, if the phone receives a click on the payment app icon, it can display the following: Figure 7 The interface 701 shown in (b) is used to replace the application interface provided by the payment application, thereby prompting the user to disable the payment application.

[0154] In addition to setting the permission to enable child control mode, the phone can also set the duration for which child control mode is available.

[0155] In some embodiments, such as Figure 8 As shown in (a), when a user clicks the application limit control in interface 506, the phone receives the user's click action on the application limit control. In response to this click action, the phone displays as shown... Figure 8 Interface 801 is shown in (b) above. Interface 801 also includes multiple application identifiers indicating the applications. Interface 801 also includes time limit markers corresponding to the application identifiers. These time limit markers indicate the available time of the application. For example, a time limit marker corresponding to a short video app can indicate that the available time of the short video app is 1 hour. Similarly, a time limit marker corresponding to a homework tutoring app can indicate that the available time of the homework tutoring app is unlimited. And again, a time limit marker corresponding to a weather app can indicate that the weather app has no time limit.

[0156] Similarly, users can configure or change the aforementioned time limit markers for each application. In other words, users can independently determine the available time for different applications through operations in interface 801. Thus, in the child control mode corresponding to "Dabao," the phone can limit the available time of each application according to its time limit marker. In subsequent embodiments, the application with available time limits will be referred to as application 1.

[0157] In some embodiments, under child control mode, the mobile phone can also track the actual usage time of each application 1.

[0158] As one implementation method, in the child control mode for designated children, the mobile phone can accumulate the usage time of application 1, such as called duration 1, as the actual usage time of application 1.

[0159] As another implementation, when a mobile phone and other terminals (such as a tablet) share the same account or can be interconnected, the mobile phone and tablet belong to the same terminal system. For ease of description, the tablet can be referred to as the first device, and the mobile phone as the second device. The first and second devices can synchronize pre-configured child control modes in advance. For example, the mobile phone may be configured with basic information for child 1 (i.e., the first child), usage restrictions for applications, and usage status restrictions for the mobile phone itself. When a communication connection is established between the mobile phone and the tablet, such as through Bluetooth or by connecting to the same local area network, the mobile phone can send the configured information to the tablet, thereby achieving synchronization between multiple devices.

[0160] In this way, after the tablet unlocks, while displaying the desktop (referred to as the second interface), the tablet can collect the current user's second biometric feature. This second biometric feature includes at least one of the user's facial features, iris features, fingerprint features, and voiceprint features. By comparing the second biometric feature with the basic information of a designated child, it is determined whether the user indicated by the second biometric feature is the designated child. If the second biometric feature indicates that the user is the designated child, e.g., child 1, the tablet activates the child control mode corresponding to child 1. During the activation of child control mode for child 1, the tablet can accumulate the usage time of application 1 (e.g., the first application), referred to as duration 2 (i.e., the first duration). After the tablet detects that it has entered a locked screen state or that application 1 has been closed, it sends indication information 1 to the mobile phone, referred to as the first information. Indication information 1 includes the duration 2 corresponding to application 1.

[0161] Thus, after the phone is unlocked, during the display of the desktop (e.g., the first interface), the phone can collect the current user's first biometric feature. This first biometric feature includes at least one of the user's facial features, iris features, fingerprint features, and voiceprint features. When the first biometric feature indicates the user is a child (1), the phone activates the child control mode corresponding to child (1). During the activation of child control mode for child (1), the phone can also accumulate the usage time (1) of application (1) (i.e., the second usage time). Afterwards, the phone can combine usage time (1) and usage time (2) to obtain the actual usage time of application (1). Of course, after the phone enters the lock screen state, the phone can also send indication information (2) to the tablet. This indication information (2) includes the usage time (1) corresponding to application (1). Thus, when the tablet recognizes the user as a designated child, it can also combine usage time (1) to determine the actual usage time of application (1).

[0162] When the actual usage time exceeds the available time of application 1 (i.e., the first time value), the phone can restrict the use of application 1.

[0163] For example, such as Figure 8As shown in (b), in the child control mode corresponding to DaBao, the available time for the short video application is 1 hour. Based on the collected facial feature 2, the phone identifies the current user as DaBao. The phone can then enable the child control mode corresponding to DaBao. The phone can count the display time of the short video interface to determine the actual usage time of the short video application. If the determined actual usage time exceeds 1 hour, such as... Figure 9 As shown, the phone displays a prompt box 902 in the short video interface 901, which may be referred to as the first prompt window. This prompt box 902 is used to inform the user that they cannot continue using the short video application. Additionally, while the prompt box 902 is displayed, the phone can pause the application services provided by the short video application, for example, by displaying a blurred short video interface, or by pausing video file playback.

[0164] Additionally, if the available time limit for time 2 has been exceeded, after the phone receives the first message and activates the child control mode corresponding to child 1, it will prohibit the use of the first application. For example, when the phone receives a user's operation on the application icon of the first application (i.e., the first icon), the phone may display the application lock screen, or it may not respond to operations on the first icon.

[0165] In some embodiments, the phone can also configure prohibited periods for applications based on the user's actions regarding the disabled period control. Thus, when a child control mode is specified, if the phone determines that the system time falls within a prohibited period, it can disable the corresponding application.

[0166] In addition to controlling application access permissions and time limits, the phone can also manage the user's phone usage status in child control mode. Therefore, in some embodiments, the phone's interface 506 may also include multiple device restriction configuration items. These device restriction configuration items can be used to enable restrictions on the device's usage status. Different device restriction configuration items correspond to different usage status restrictions. For example, device restriction configuration items may include an "ambient light management" control and a "view distance management" control. The "ambient light management" control enables ambient light restrictions for the phone, while the "view distance management" control enables distance restrictions between the phone and the user, such as a human-machine distance restriction.

[0167] In some embodiments, users can operate on device restriction configuration items in interface 506 to trigger the phone to enable or disable the corresponding usage state restrictions.

[0168] When the mobile phone enables human-machine distance restrictions, such as Figure 10 As shown, the mobile phone can detect the distance between the user and the screen in real time, which is also known as the first distance.

[0169] In some embodiments, after the phone is unlocked, it begins collecting facial features. After determining that the user is a child based on the collected facial features, the phone activates the corresponding child control mode. During child control mode, the phone continues to collect facial features and, based on these features, determines the distance between the user and the display screen.

[0170] As an example, a mobile phone can use image information captured by its front-facing camera to determine the aforementioned human-machine distance through image analysis. For instance, the phone can obtain the area occupied by the user's eyes in the image information. Based on the proportion of this area in the image information, the human-machine distance is evaluated. Another example is that the phone can obtain the user's interocular distance from the image information and evaluate the human-machine distance accordingly. As yet another example, a distance-measuring sensor, such as a radar sensor or a proximity sensor, can be installed on the side of the phone's display screen. In this way, the phone can directly collect the human-machine distance through this distance-measuring sensor.

[0171] After obtaining the human-machine distance, the mobile phone can compare the above human-machine distance with a preset value (also known as a preset distance value). The above preset value can be a distance value preset in the mobile phone, for example, the preset value can be 25cm.

[0172] If the measured human-machine distance is less than a preset value, the phone will issue a distance alert. It will also record the distance and the corresponding detection time, generating a usage report. If the measured distance is not less than the preset value, the phone will not issue an alert to avoid affecting normal user operation.

[0173] Thus, as Figure 11 As shown in (a), when the phone screen is on, such as while displaying a short video interface, the phone detects a human-phone distance of d1. The phone determines that d1 is not less than 25cm, and continues to display the short video interface normally while continuing to detect the human-phone distance to avoid affecting normal user operation. Additionally, as shown in (a), Figure 11 As shown in (b), when the phone is in screen-on mode, such as while displaying a short video interface, the phone detects a human-phone distance of d2. If the phone determines that d2 is less than 25cm, it displays a reminder box 1101, also known as a second prompt window, prompting the user to adjust the distance between themselves and the phone. Of course, voice prompts can also be provided while reminder box 1101 is displayed. Similarly, the phone will continue to detect the human-phone distance until it detects a distance of at least 25cm, at which point it will remove reminder box 1101.

[0174] In other possible embodiments, while the phone is displaying an application interface, such as a short video interface, the short video interface can be blurred after the notification box 1101 is displayed. This prevents the user from continuing to view content displayed outside the notification box 1101 on the screen. Furthermore, the short video application can be controlled to pause providing application services, such as pausing short video playback or turning off audio playback. While the phone is displaying the desktop, including the notification box 1101, the icons of applications on the desktop become untouchable, for example, the phone disables the calling interfaces of each icon.

[0175] When the phone's ambient light limit is enabled, such as Figure 12A As shown, the phone detects the ambient light level, i.e., the ambient light intensity. If the ambient light level meets the requirements, the phone continues to detect the ambient light without issuing a warning. If the ambient light level does not meet the requirements, the phone can issue an ambient light warning. It also records the ambient light level and the corresponding detection time, generating a usage report. Understandably, the above requirement could be that the ambient light level is not lower than a specified illuminance value (such as a preset light threshold), such as 50 lux. When the ambient light level is below 50 lux (i.e., the ambient light level does not meet the requirements), it indicates that the lighting environment in which the phone is located is poor. Using the phone in this situation could negatively impact the user's eyes, requiring careful management of phone usage.

[0176] Of course, methods for controlling mobile phone usage can include: displaying a notification box (i.e., a third-party notification window), pausing application services, making application icons untouchable, and blurring the display interface. For details, please refer to the aforementioned embodiments regarding the control methods for human-machine distance, which will not be elaborated upon here.

[0177] In other embodiments, the phone can also manage the user's attention span in child control mode. Prior to this, the user can configure an application on the phone to monitor attention span, such as application 2. When application 2 is enabled, the phone can determine whether the user's attention span meets the requirements by detecting the duration of the user's gaze at the screen. If the requirements are not met, an attention span reminder will be issued.

[0178] For example, based on the user's configuration, the phone determines that the homework tutoring app belongs to app 2. Furthermore, the interface provided by the homework tutoring app can be called the homework tutoring interface. Thus, when the phone is running in child control mode, it acquires image information from the front-facing camera in real time while displaying the homework tutoring interface. The phone analyzes the user's eye position and angle in the image information to determine whether the user is looking at the phone's screen. If the phone determines that the user is looking at the screen, it starts timing. If the phone determines that the user is not looking at the screen, it stops timing, thus obtaining the duration of the user's gaze at the screen. If the ratio of the gaze duration to the total time spent displaying the homework tutoring interface is lower than a preset value, it is determined that the user's attention level does not meet the requirements. At this time, the phone may display a reminder window or play voice data to prompt the user to concentrate. If the ratio of the gaze duration to the total time spent displaying the homework tutoring interface is not lower than the preset value, it is determined that the user's attention level meets the requirements. At this time, the phone does not issue a reminder and continues to count the user's gaze duration at the screen.

[0179] In some embodiments, a mobile phone can be configured with multiple child control modes, each designed for a specific child. This allows for targeted child control. For example, the mobile phone can configure multiple child control modes based on user actions.

[0180] In some embodiments, the phone's interface 506 also includes controls for instructing the creation of a child control mode, such as... Figure 12B The control 1201 is shown in (a) above. When the mobile phone receives an operation from the user on the control 1201, it initiates the process of creating a child control mode. That is, the mobile phone can display as shown in (a). Figure 12B Interface 1202 is shown in (b) above. Interface 1202 includes a face addition window 1203.

[0181] For example, when the mobile phone receives an operation from the user on the face addition window 1203, such as clicking the operation, it can display... Figure 12B The gallery interface 1204 is shown in (c). This gallery interface 1204 includes multiple photos. The user can select a photo containing a face image from the multiple photos, such as photo 1205. Thus, after the mobile phone receives the user's operation on photo 1205, it can identify the face image in photo 1205 as the newly added profile picture of the specified child.

[0182] For example, after receiving the user's operation on the face addition window 1203, the mobile phone can activate the camera and display the corresponding viewfinder. In this way, the mobile phone captures a photo containing a face image according to the user's instructions and identifies the photo as the newly added portrait information of the specified child.

[0183] In some embodiments, interface 1202 may further include an input field 1206. This input field 1206 is used to receive a date entered by the user, and the mobile phone can determine the age of the newly added specified child based on the date entered by the user. Additionally, while the mobile phone displays interface 1202, it can also receive a child identifier entered by the user, such as "second child".

[0184] After configuring basic information such as profile picture, age, and child identification, the user can instruct the phone to add a specified child by operating the confirmation control 1207. Upon receiving the user's operation on the confirmation control 1207, the phone can create an information card corresponding to the newly added specified child based on the user-configured basic information, such as a card for the second child. This newly added information card displays the basic information of the newly added specified child. Furthermore, when creating the basic information of a specified child, at least one of the child's iris features, fingerprint features, and voiceprint features can also be entered, thus giving the phone more ways to distinguish whether the user is the specified child.

[0185] In addition, the mobile phone can also determine the corresponding child control mode for newly added designated children.

[0186] In some examples, different age groups can correspond to different general child control modes. The general child control mode for each age group can be applied to most children within that age group. In this way, the phone can obtain the corresponding general child control mode based on the age of the newly added child, and use this mode as the child control mode for that child.

[0187] For example, Child Control Mode 1 is suitable for most children aged 3-6. Child Control Mode 2 is suitable for most children aged 7-14. When adding a designated child who is 4 years old, the phone can access Child Control Mode 1 to use as the child control mode for the newly added designated child.

[0188] In some embodiments, after determining the child management mode corresponding to the newly added specified child, such as Figure 13 As shown in (a), the mobile phone can display interface 1301.

[0189] Interface 1301 includes a card set. This card set includes at least one information card. Different information cards are used to display basic information about different designated children. That is, different information cards correspond to different designated children.

[0190] Additionally, the card set is displayed in a stacked manner on interface 1301. For example, only the top card of the card set, such as card 507, is displayed on the phone's interface 1301. While the phone is displaying interface 1301, the child control mode corresponding to the top card can be adjusted according to the user's operation, such as adjusting the child control mode for the older child. The specific adjustment process can be referred to the aforementioned embodiment and will not be repeated here.

[0191] Additionally, interface 1301 includes a navigation bar. This navigation bar corresponds to the card set. It indicates to the user that the card set also includes other cards, and the user can switch between displaying these other cards by interacting with card 507.

[0192] Thus, when the phone receives the user's swipe gesture on card 507, such as Figure 13 As shown in (b), the mobile phone can display interface 1302. Interface 1302 displays switched information cards, such as card 1303. Card 1303 is used to display basic information about the second child. While the mobile phone displays interface 1302, the phone can adjust the child control mode corresponding to card 1303 based on the user's operations on interface 1302, such as adjusting the child control mode corresponding to the second child. The specific adjustment process can be referred to the aforementioned embodiments and will not be repeated here.

[0193] In this way, when the phone identifies different designated children, it can run different child management modes, thus achieving targeted management.

[0194] For example, after configuring at least two designated child control modes in the mobile phone as described in the above embodiments, such as... Figure 14 As shown, after the phone is unlocked, it collects facial features and performs facial analysis. For example, the phone compares the collected facial feature 2 with the facial features 3 corresponding to Child 1 (i.e., the first child) and Child 2 (i.e., the second child). Child 1 and Child 2 are designated children. The facial feature 3 corresponding to Child 1 can be a facial feature extracted from Child 1's portrait information; similarly, the facial feature 3 corresponding to Child 2 can be a facial feature extracted from Child 2's portrait information. When it is determined that the facial feature 2 collected by the phone matches the facial feature 3 of Child 1, Child Control Mode 1 corresponding to Child 1 is activated. At this time, the phone uses the permission list of Child Control Mode 1, also known as the first restriction condition, to control the use of the phone. When it is determined that the facial feature 2 collected by the phone matches the facial feature 3 of Child 2, Child Control Mode 2 corresponding to Child 2 is activated. At this time, the phone uses the permission list of Child Control Mode 2, also known as the second restriction condition, to control the use of the phone.

[0195] Understandably, the above permission list includes restrictions on application usage and phone usage status under the corresponding child control mode. Once the child control mode is configured, the permission list for that specific child is also determined.

[0196] Additionally, after the phone is in Child Control Mode 1, it continues to collect facial features. If the phone determines that the current user has become a child (child 2) based on the newly detected facial feature (child 2), the phone can switch from Child Control Mode 1 to Child Control Mode 2.

[0197] For example, such as Figure 14 As shown, after the phone is unlocked, facial feature 2 is captured for the first time. Through facial analysis, it is determined that the user indicated by facial feature 2 does not include a child. The phone then enters normal mode. In normal mode, the user can instruct the activation of any child control mode. For example, the user can manually activate child control mode 1 corresponding to child 1, or manually activate child control mode 2 corresponding to child 2. As one implementation method, the phone can be configured with a control for switching between different child control modes. The phone can switch from normal mode to any child control mode based on the user's operation of this control.

[0198] In addition, in normal mode, the phone continues to collect facial features. Based on the newly detected facial feature 2, the phone determines that the current user has become Child 1 or Child 2. The phone can then switch from normal mode to Child Control Mode 1 or Child Control Mode 2.

[0199] In some embodiments, when the phone identifies multiple users, if it determines that there is only one designated child among the multiple users, the phone directly runs the child management mode for that designated child. If the phone determines that there are multiple designated children among the multiple users, the phone needs to determine the target management mode based on the child management modes for multiple designated children. Then, the phone runs in that target management mode.

[0200] As one implementation, when a mobile phone identifies that the user includes multiple designated children, it can obtain a permission list corresponding to each child. This permission list includes the applications that are restricted to the designated children and their corresponding usage limits. Understandably, the usage limit for a prohibited application is 0 minutes. Then, these multiple permission lists are merged to obtain a merged permission list, also known as a third restriction. This merged permission list includes all disabled applications from the multiple permission lists. Furthermore, when multiple permission lists indicate that the same application corresponds to multiple available usage limits, the shortest of these limits can be determined as the available usage limit for that application in the merged permission list. For example, ... Figure 15As shown, in Da Bao's permission list, the available time for the short video app is 1 hour (first time value), while in Er Bao's permission list, the available time for the short video app is 20 minutes (third time value). The permission lists of Da Bao and Er Bao are merged to obtain a shared permission list, i.e., a merged permission list. In the merged permission list, the available time for the short video app is 20 minutes (second time value). Subsequently, during the operation of this target control mode on the phone, the use of applications on the phone can be restricted according to the corresponding merged permission list.

[0201] S104: When the phone receives a user instruction to exit the child control mode, it switches to the corresponding normal mode.

[0202] In some embodiments, if the phone switches from parental control mode to normal mode, the restrictions on application usage (such as enable permissions, available time and shutdown periods) and restrictions on device usage status (such as human-device distance restrictions and environmental light restrictions) imposed by the parental control mode are directly removed.

[0203] For example, while the phone is running in parental control mode, it can receive a user instruction to exit parental control mode, such as a designated action. Afterwards, the phone can switch to normal mode in response to the designated action, such as making a designated gesture or clicking a designated button. As another example, before switching to normal mode, the phone can also prompt the user again for password or facial verification; if the verification is successful, the phone switches to normal mode.

[0204] In other embodiments, when the phone recognizes that the user has changed from a child to an adult, it can automatically switch from child control mode to normal mode. The phone automatically removes the usage restrictions corresponding to child control mode. This way, the user does not need to manually restore phone permissions when using the phone normally, improving the user experience.

[0205] In other embodiments, the phone can also aggregate various usage reports generated during child control mode, such as reports on human-machine distance detection, ambient light detection, attention detection, and phone usage time. This allows the owner to easily understand the child's actual phone usage.

[0206] In summary, the method provided in this application allows users to set device usage permissions for children on the terminal device. Thus, during actual operation, the terminal device can automatically identify whether the current user is a child without the user's awareness, enabling the terminal device to intelligently switch to child control mode. Furthermore, multiple terminal devices can share information about the same child's device usage under child control mode, improving the accuracy of control. In this way, precise control can be achieved without long-term parental monitoring during child device use, improving the efficiency of human-computer interaction.

[0207] This application also provides a terminal device, which may include a memory and one or more processors. The memory and processors are coupled.
