In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic implementation flowchart of a control method of a mobile terminal according to an embodiment of the present application, and as shown in the figure, the method may include the following steps:
and S101, intercepting a screen touch event of the mobile terminal under a preset trigger mechanism, and starting a front camera.
In this embodiment of the application, the preset trigger mechanism indicates a condition that a user may generate a screen mis-touch event to the mobile terminal, for example, it is detected that a screen of the mobile terminal is downward, and a face image is detected in a preview image currently acquired by a rear camera, which indicates that eyes of the user are not currently directed toward the screen, and a screen touch event received by the screen of the mobile terminal may be the screen mis-touch event, where the screen mis-touch event indicates that the user does not intend to operate the mobile terminal, but the mobile terminal receives a touch instruction.
As another embodiment of the present application, the preset trigger mechanism further includes: and if the preset application of the mobile terminal is in a foreground running state, and the azimuth change amplitude of the mobile terminal is monitored to be larger than a preset value.
In this embodiment of the application, the preset application may be a reading application, for example, an electronic book-related application, a social-related application, a shopping-related application, and the like, and a plurality of preset applications may be set, and as long as any one of the preset applications runs in a foreground and the detected change range of the orientation of the mobile terminal is greater than a preset value, the preset trigger condition is met, because when the user views the reading application, since the user needs to look at a screen of the mobile terminal with eyes, the mobile terminal is usually held in the hand of the user, and the user usually stabilizes the mobile terminal at a position in order to obtain a good reading experience. However, when the user holds the mobile terminal in his hand, it is impossible to keep the mobile terminal completely still, and the orientation of the mobile terminal changes, and at this time, a value (preset value) may be set, where the preset value indicates the change range of the orientation of the mobile terminal when the user reads, and when the change range of the orientation of the mobile terminal is monitored to be greater than the preset value, it indicates that the user may not read any more, for example, the user needs to deal with an emergency event urgently and places the mobile terminal in a pocket. In order to avoid the screen error touch event, the screen touch event of the mobile terminal can be intercepted. In practical application, it may also be set that no response is generated to the screen touch event of the mobile terminal, and after the screen touch event of the mobile terminal is intercepted or the screen touch event of the mobile terminal is not responded, no response is generated to the mobile terminal through operations such as clicking, sliding and the like generated on the screen of the mobile terminal by the user.
And step S102, carrying out face detection on the preview image acquired by the front camera in real time.
In the embodiment of the present application, even if the preset trigger mechanism is met, there may be a situation that the user is still reading, for example, when the user changes from holding the mobile terminal left or right to holding the mobile terminal right, the user is still reading. At this time, it is necessary to further confirm whether the user is currently reading, for example, a front camera of the mobile terminal may be turned on, a preview image of a front area is acquired by the front camera in real time, and face detection is performed on the preview image acquired by the front camera in real time, where the face detection is only used to identify whether the user is currently watching a screen of the mobile terminal, and is not used for authentication.
The process of face detection can be realized by the following method: firstly, designing one or more standard face templates, namely, judging whether a face exists or not for a preview image or a shot picture acquired by a front camera based on face features of a person (because the face has certain structural distribution features, such as the size, the position, the distance and other attributes of facial image facial contours of an iris, a nasal wing, a mouth corner and the like), further giving the position and the size of the face and position information of each main facial organ if the face exists, calculating the matching degree between the detected face features and the standard templates by adopting an Adaboost learning algorithm based on the face features, and judging whether the face exists or not by a threshold value.
It should be noted that the preview image or the shot picture collected by the front-facing camera may not be directly subjected to face detection due to the limitation of natural condition factors, and before the face detection is performed, preprocessing needs to be performed on the preview image or the shot picture collected by the front-facing camera, such as noise filtering, light compensation, gray scale transformation, histogram equalization, normalization, geometric correction, filtering, sharpening, and the like.
And step S103, if a human face image is detected in the preview image acquired by the front camera in real time, the interception of the screen touch event is released.
In this embodiment of the application, if the matching degree between the preview image or the shot picture acquired by the front-facing camera and the standard template is greater than a threshold, it indicates that a face image is detected, and if the matching degree between the preview image or the shot picture acquired by the front-facing camera and the standard template is less than or equal to the threshold, it indicates that a face image is not detected. And if the detected face image indicates that the user is reading currently, the interception of the screen touch event can be released, and at the moment, if the user performs sliding, clicking and other operations on the touch screen, the mobile terminal can generate corresponding response.
The embodiment of the application intercepts the screen touch event of the mobile terminal under a preset trigger mechanism, and starts the front camera, and carries out face detection on the preview image acquired by the front camera in real time, if the face image is detected in the preview image acquired by the front camera in real time, the interception of the screen touch event is removed, because the screen touch event of the mobile terminal is intercepted under the preset trigger mechanism, the screen false touch event of a user is avoided, and the face detection is carried out through the preview image acquired by the front camera in real time, if the face image is detected in the preview image acquired by the front camera in real time, the user indicates that the user is currently still using the mobile terminal, at the moment, the interception of the screen touch event is removed, the screen false touch event of the user is avoided, and the use state of the mobile terminal is further confirmed through the camera, in the whole process, the physical keys of the mobile terminal do not need to be operated, so that the damage to the physical keys is reduced.
Fig. 2 is a flowchart illustrating a control method of a mobile terminal according to another embodiment of the present application, where as shown in the figure, the method may include the following steps:
step S201, if the preset application of the mobile terminal is in a foreground running state and the azimuth change amplitude of the mobile terminal is monitored to be larger than a preset value, intercepting a screen touch event of the mobile terminal, starting a front camera and starting a timer.
In the embodiment of the application, the preset application is in a foreground running state, which means that the preset application runs directly in a window, and the mobile terminal displays an interface interacting with a user of the mobile terminal.
The azimuth change amplitude of the mobile terminal is obtained through the following modes:
Fj+1＝αj+1-αj，
wherein j represents the jth time period, Fj+1Indicating the magnitude of the azimuth change of the mobile terminal at time period j +1, αjRepresenting the mean value of the azimuth angles of the mobile terminal, which are obtained by the magnetic field sensor and the acceleration sensor of the mobile terminal in the jth time period, n representing the azimuth angles of n mobile terminals obtained by sampling the magnetic field sensor and the acceleration sensor of the mobile terminal in each time period, and thetaiAnd sampling a magnetic field sensor and an acceleration sensor representing the mobile terminal to obtain the ith azimuth angle.
As an example, assuming that the time period is 1 minute, the magnetic field sensor and the acceleration sensor of the mobile terminal sample and obtain azimuth angles of 6 mobile terminals in each time period (obtained every 10 seconds), where n is 6, and the start time of monitoring the azimuth change amplitude of the mobile terminal is: 12:00:00, then:
the first time period is 12:00:00-12:01:00, and the obtained sampling point is theta1、θ2、θ3、θ4、θ5、θ6，
The second time period is 12:01:00-12:02:00, and the obtained sampling point is theta7、θ8、θ9、θ10、θ11、θ12，
The third time period is 12:02:00-12:03:00, and the obtained sampling point is theta13、θ14、θ15、θ16、θ17、θ18，
The average value of the azimuth angles sampled in the third time period is α3＝(θ13+θ14+θ15+θ16+θ17+θ18) 6 according to the formula
It can be derived that:
similarly, the average value of the azimuth angles sampled in the second time period is α2＝(θ7+θ8+θ9+θ10+θ11+θ12) 6 according to the formula
It can be derived that:
subtracting the average value of the azimuth angles of the second time period from the average value of the azimuth angles of the third time period to obtain the azimuth change amplitude F of the mobile terminal in the current third time period3＝α3-α2。
It should be noted that, the starting time for monitoring the azimuth variation amplitude of the mobile terminal may be a time when the preset application starts to start, and when each time period ends (for example, a third time period ends), the azimuth variation amplitude of the mobile terminal in the current time period (the third time period) may be obtained according to the average value of the azimuth in the current time period (the third time period) and the previous time period (the second time period).
The intercepting of the screen touch event of the mobile terminal comprises:
and adding a frame layout in a system unlocking screen interface to prevent the transmission of a screen touch event of the mobile terminal.
Specifically, a layer of FrameLayout is added to keyguard host to serve as a mask, so that gesture events of the touch screen are prevented from being transmitted downwards (to an underlying system).
Step S202, carrying out face detection on the preview image acquired by the front-facing camera in real time;
the step is consistent with the content of step S102, and the description of step S202 may be specifically referred to, which is not repeated herein.
Step S203, before the timing time of the timer is greater than a first preset time, if a human face image is detected in a preview image acquired by the front camera in real time, the interception of the screen touch event is removed.
In the embodiment of the application, a timer is also required to be started when the screen touch event of the mobile terminal is intercepted and the front camera is started. Before the timing time of the timer is longer than a first preset time, if a face image is detected in a preview image acquired by the front-facing camera in real time, the user is indicated to be currently using the mobile terminal, and at this time, the interception of the screen touch event needs to be removed, so that the user can continue to operate the mobile terminal.
The timer is started because: if the user does not use the mobile terminal for a long time, that is, the face image is not detected in the preview image acquired by the front camera of the mobile terminal, the front camera is required to acquire the preview image and perform face detection until the face image is detected in the preview image acquired by the front camera in real time, and a time value (first preset time) can be set to avoid a large amount of memory consumption.
It should be noted that, after the face image is detected, it indicates that the user is currently using the mobile terminal, and the front-facing camera may be closed, and meanwhile, whether the preset trigger mechanism is met or not is continuously monitored.
And step S204, before the timing time of the timer is greater than a first preset time, if no human face image is detected in the preview image acquired by the front camera in real time, the interception of the screen touch event is released when the timing time of the timer is greater than the first preset time.
In the embodiment of the application, if no human face image is detected in the preview image acquired by the front camera in real time before the timing time of the timer is greater than a first preset time, the interception of the screen touch event is released when the timing time of the timer is greater than the first preset time.
It should be noted that, because the face is not detected all the time, it may be that the user is not currently using the mobile terminal, at this time, the turned-on front-facing camera may be turned off, and whether the preset trigger mechanism is met is no longer monitored.
As can be seen from the descriptions of step S203 and step S204, the trigger condition for releasing the interception of the screen touch event is: 1) detecting a face image in a preview image acquired by the front-facing camera in real time before a first preset time, and removing the face image when the face image is detected; 2) and before the first preset time, the preview images acquired by the front camera in real time are all free of human face images, and then the preview images are released after the first preset time.
For example, assuming that the first preset time is set to be 2 minutes, if a face image is detected in the 1 st minute, the interception of the screen touch event is released in the 1 st minute, and meanwhile, the front-facing camera can be turned off and whether a preset trigger mechanism is met or not can be continuously confirmed; if the face image is not detected within 2 minutes, the interception of the screen touch event is released in the 2 nd minute, and meanwhile, the front camera can be closed, but whether a preset trigger mechanism is met or not can not be continuously confirmed.
Step S205, if the user operation is not detected within a second preset time after the interception of the screen touch event is released, performing a screen-off or screen-locking operation on the mobile terminal.
In the embodiment of the application, after interception of the screen touch event is released, no matter whether a user uses the mobile terminal currently, as long as an operation of the user is not detected within a second preset time, screen turning or screen locking operation is performed on the mobile terminal.
The embodiment of the application further details how to determine the azimuth change amplitude of the mobile terminal on the basis of the embodiment shown in fig. 1, and also increases the limit of the first preset time, so that the real use state of the mobile terminal can be more accurately judged.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
