Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the control method for locking a screen provided by the present disclosure, an application scenario related to the present disclosure is first introduced, where the application scenario may include a terminal. The terminal may be a mobile terminal device having a screen lock function or supporting a third-party screen lock application plug-in, and may be, for example, a smart phone, a tablet computer, a smart television, a smart watch, a PDA (Personal Digital Assistant), a portable computer, or the like.
Fig. 1 is a flowchart illustrating a method for controlling a lock screen according to an exemplary embodiment, as shown in fig. 1, referring to fig. 1, the method for controlling a lock screen may be applied to a terminal described in the above application scenario, and the method may include the following steps.
In step 101, the number of consecutive occurrences of a quick unlock event, which is an event unlocked within a first preset time after the screen is locked, is determined.
For example, the number of continuous occurrences of the quick unlocking event before the current unlocking can be determined after the screen is unlocked. The first preset time may be a shorter time interval. Taking the terminal as a mobile phone as an example, the quick unlocking event may include: when a user reads news by using the mobile phone, the screen of the mobile phone is locked after a period of time because no operation is performed in the reading process. This time interval may be in the range of 2 to 5 seconds, when the user finds the screen locked and unlocks immediately to continue reading.
In step 102, when the continuous occurrence number is greater than a preset number threshold, the screen locking time of the screen is extended, where the screen locking time is a time from when the screen does not receive an operation to when the screen is automatically locked.
Illustratively, when a user uses the terminal, if the screen is unlocked immediately after being locked several times in succession, this indicates that the current screen locking time of the system is too short for the scene used by the user, so it is necessary to extend the screen locking time.
To sum up, the control method for locking a screen according to the embodiment of the present disclosure determines the continuous occurrence frequency of a fast unlocking event, where the fast unlocking event is an event that is unlocked within a first preset time after the screen is locked; and when the continuous occurrence frequency is greater than a preset frequency threshold value, prolonging the screen locking time of the screen, wherein the screen locking time is the time from the moment that the screen does not receive the operation to the moment that the screen is automatically locked. According to the method and the device, the time for locking the screen can be automatically adjusted according to the condition that the user uses the mobile phone, and the unlocking times of the user when the user watches the screen for a long time are reduced.
Fig. 2 is a flowchart illustrating a method for extending the screen lock time of the screen according to the embodiment shown in fig. 1, and as shown in fig. 2, step 102 may include the following steps.
In step 1021, when the number of consecutive occurrences is greater than the preset number threshold, a prompt message indicating whether to unlock the intelligent screen locking function is displayed.
For example, when the terminal detects that the user unlocks the screen immediately after the screen is locked for multiple times, an option of whether to start the intelligent screen locking function can be displayed to the user, and when the user selects not to start the intelligent screen locking function, the current screen locking time is kept unchanged; when the user selects to turn on the smart lock screen function, the process proceeds to step 1022.
In step 1022, when an instruction for determining to unlock the intelligent screen locking function is received, the screen locking time of the screen is extended.
Optionally, the extending the screen locking time of the screen in step 1022 may include: and adjusting the screen locking time from the default first screen locking time to a second screen locking time, wherein the time length of the second screen locking time is n times of the first screen locking time.
For example, when the user determines to turn on the intelligent screen locking function, the terminal system may increase the current screen locking time to be 5 seconds to twice the current screen locking time. At this time, the lock screen time becomes 10 seconds. Further, after the screen locking time is changed to 10 seconds, when the system detects that the user unlocks the screen immediately after the screen is locked for multiple times, the screen locking time can be continuously increased to twice the current screen locking time of 10 seconds, namely 20 seconds.
Optionally, when no operation is detected on the screen within a second preset time after the current unlocking, the extending the screen locking time of the screen in step 1022 may further include:
firstly, adjusting the brightness of the screen from the current first brightness to a second brightness, wherein the second brightness is lower than the first brightness;
secondly, when an operation is detected on the screen within a third preset time after the screen is adjusted to the second brightness, the brightness of the screen is adjusted to the first brightness, the screen locking time is adjusted from the second screen locking time to a third screen locking time, and the time length of the third screen locking time is m times of the second screen locking time.
Illustratively, the screen locking process of the terminal may include: when the terminal system does not detect the operation behavior of the user on the terminal within a period of time, the brightness of the screen can be reduced to a second brightness, and the period of time can be a second preset time; after the screen brightness is adjusted to the second brightness, if the terminal system still does not detect the operation behavior of the terminal by the user within the next period of time, it may be determined that the screen is locked, and the period of time may be a third preset time. And the sum of the second preset time and the third preset time is equal to the second screen locking time.
For example, taking the second screen locking time as 10 seconds as an example, when the terminal system detects the operation behavior of the user on the terminal within the third preset time, the screen may be restored to the first brightness, and then the current screen locking time is increased to twice the current second screen locking time by 10 seconds. At this time, the lock screen time becomes 20 seconds. When the system detects the operation behavior of the user on the terminal within the third preset time again, the current screen locking time can be continuously increased to twice the current second screen locking time by 20 seconds, namely 40 seconds.
Fig. 3 is a flowchart illustrating another method for controlling screen locking according to an exemplary embodiment, and as shown in fig. 3 and referring to fig. 3, the method for controlling screen locking may be applied to a terminal described in the above application scenario, and the method may further include the following steps.
In step 103, after the screen is locked, whether a face entering the face detection range exists is detected.
The face detection range may include a shooting range of a camera on the terminal, or a detection range of a face detection device in the terminal.
In step 104, it is determined whether the user to which the face belongs is the user before the screen lock.
For example, before the screen is locked, the terminal system may capture and store the second facial feature or the second iris feature of the terminal user through a camera or a face detection device. After the screen is locked, the currently acquired first facial feature may be compared with the second facial feature, and when the first facial feature and the second facial feature are confirmed to be consistent, the process proceeds to step 105. Or the first iris feature currently acquired may be compared with the second iris feature, and when the two iris features are confirmed to be consistent, the process proceeds to step 105.
In step 105, the screen is unlocked.
Fig. 4 is a flowchart illustrating an unlock screen according to the embodiment shown in fig. 3, and as shown in fig. 4, step 105 may include the following steps.
In step 1051, when the user to which the face belongs is the same user as the user before the screen is locked, the screen is unlocked.
In step 1052, the page before the screen lock is displayed on the screen.
Illustratively, after the screen lock is released, the content browsed by the user before the screen lock is displayed on the terminal screen, so that the user does not need to search the content before the screen lock or the operation before the screen lock again.
Fig. 5 is a flowchart illustrating an embodiment of determining a user to whom a face belongs according to fig. 3, and as shown in fig. 5, the step 104 of determining whether the user to whom the face belongs is the user before the screen is locked may include the following steps.
In step 1041, when a face entering the face detection range is detected, face recognition is performed on the face to obtain a first facial feature of the face.
In step 1042, the first facial feature is compared to a second facial feature of the face captured before the screen lock.
In step 1043, when the first facial feature is consistent with the second facial feature, it is determined that the user to which the face belongs is the user before the screen lock.
For example, after the terminal screen is locked, when the user wants to unlock the screen, the face may be brought close to the terminal, and the terminal may collect a first face feature of the user and compare the first face feature with a second face feature collected in advance before the screen is locked, and when the first face feature is consistent with the second face feature, the user identity is determined.
Therefore, the user can perform screen unlocking operation by identifying the facial features through the terminal, so that the user does not need to vacate hands to perform screen unlocking operation, or the user can unlock the screen and watch the content before the screen is locked when the user inconveniently touches the screen with both hands.
Fig. 6 is a flowchart illustrating another method for determining a user to whom a face belongs according to the embodiment shown in fig. 3, and as shown in fig. 6, the determining of whether the user to whom the face belongs is the user before the screen is locked in step 104 may further include the following steps.
In step 1044, when a face entering the face detection range is detected, the eye position in the face is obtained.
In step 1045, iris recognition is performed on the eye location to obtain a first iris feature.
In step 1046, the first iris feature is compared to a second iris feature obtained from the face captured prior to the screen lock.
In step 1047, when the first iris feature is consistent with the second iris feature, it is determined that the user to which the face belongs is the user before the screen lock.
The iris feature comparison method is the same as the face feature comparison method described in fig. 5, and is not described again.
Fig. 7 is a flowchart illustrating a further method for controlling a lock screen according to an exemplary embodiment, and as shown in fig. 7, referring to fig. 7, the method may further include the following steps.
In step 106, while unlocking the screen, it is detected whether there is a human hand that enters the gesture detection range.
In step 107, when a human hand that enters the gesture detection range is detected, gesture information of the human hand is acquired.
In step 108, an operation corresponding to the gesture information is determined.
In step 109, an operation corresponding to the gesture information is performed on the page currently displayed on the screen.
For example, when the screen is unlocked, the terminal system may further capture gesture information of the user through a camera or a gesture detection device, and perform an operation corresponding to the gesture information. For example, the user may set the gesture of the page-up operation as a gesture of extending an index finger to point upwards, and when the user makes the gesture, it may be determined that the page-up operation is performed on the terminal page after the screen is unlocked. For another example, the user may set the gesture of returning to the home interface as a fist-clenching gesture, and when the user makes the gesture, the user may determine to return to the home interface of the terminal page after unlocking the screen.
Therefore, when the user inconveniently touches the screen with both hands, the user can still operate the terminal through gestures without touching the screen after unlocking the screen through the recognition of the facial features by the terminal.
To sum up, the control method for locking a screen according to the embodiment of the present disclosure determines the continuous occurrence frequency of a fast unlocking event, where the fast unlocking event is an event that is unlocked within a first preset time after the screen is locked; and when the continuous occurrence frequency is greater than a preset frequency threshold value, prolonging the screen locking time of the screen, wherein the screen locking time is the time from the moment that the screen does not receive the operation to the moment that the screen is automatically locked. According to the method and the device, the time for locking the screen can be automatically adjusted according to the condition that the user uses the mobile phone, and the unlocking times of the user when the user watches the screen for a long time are reduced.
