Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a terminal device control method according to an exemplary embodiment, which is used in a terminal device, as shown in fig. 1, and includes the following steps S101 to S103:
in step S101, it is detected whether the screen of the terminal device is placed upward.
In step S102, when it is detected that the screen of the terminal device is placed upward, it is detected whether the screen of the terminal device is moving in a direction facing the user.
In step S103, when it is detected that the screen of the terminal device is moving in a direction facing the user, the terminal device is controlled to execute a face unlocking function.
The face unlocking in the existing terminal equipment has the problem of poor experience: when the terminal device is placed on a desk, the user only wants to light the screen for watching the time, but if the terminal device enables the face unlocking function, the terminal device recognizes the face of the user when the user lights the screen and then unlocks the terminal device. But the user just wants to see the time, so that the user experience is poor. For another example: when the terminal device receives a message in a screen locking state, the screen is lightened, and similarly, if the user looks at the screen to view the received message, the terminal device directly unlocks to enter once recognizing the face of the user. Therefore, experience optimization needs to be carried out on face unlocking, face unlocking of terminal equipment is avoided under the condition that face unlocking is not needed, and user experience is effectively improved.
In practical applications, although there are many ways in which the terminal device is picked up, the various ways of picking up the terminal device can be summarized as the following way of picking up the terminal device with the screen facing up and the way of picking up the terminal device with the screen facing down.
As shown in fig. 2, the bottom of the terminal device is close to the user, and the top of the terminal device is far from the user, further, as shown in fig. 3, the screen-up pick-up mode includes a mode in which the bottom is inclined upward higher than the top when the screen is facing upward (the screen moves in a direction facing the user), and further, as shown in fig. 4, the screen-up pick-up mode includes a mode in which the bottom is inclined downward lower than the top when the screen is facing upward (the screen moves in a direction away from the user). Similarly, the way of taking up the screen downward may also include: the bottom is tilted up higher than the top when the screen is down, and the bottom is tilted down lower than the top when the screen is down.
Taking fig. 3 and fig. 4 as an example, when the terminal device is picked up in the manner of fig. 3, the use habit of the user is better met at this time, because if the bottom of the terminal device rotates downward all the time, the terminal device itself exceeds the horizontal angle, which means that the screen of the terminal device will slowly face the face, so that the face is detected by the front face recognition camera, i.e. the greater probability indicates that the user wants to use the terminal device, and the probability of face unlocking by the terminal device is greater; when the terminal device is picked up in the manner of fig. 4, the use habit of the user is not met at this time, because if the bottom of the terminal device rotates upward all the time, the terminal device exceeds the horizontal angle, which means that the back of the terminal device will slowly face the face of the user, the front face recognition camera will enter the blind area, and the face cannot be detected, that is, the small probability indicates that the user wants to use the terminal device, so that the probability of face unlocking of the terminal device is smaller.
Therefore, in the disclosure, two conditions that the screen of the terminal device is placed upwards and the screen of the terminal device moves towards the direction facing the user are used as conditions for triggering the terminal device to execute the face unlocking function, so that the terminal device can more accurately execute face recognition.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: when the fact that the screen of the terminal device is placed upwards and the screen of the terminal device moves towards the direction facing the user is detected, the terminal device is controlled to execute the face unlocking function so as to unlock the face, the situation that the terminal device does not unlock the face under the situation that the face unlocking is not needed is avoided, and user experience is effectively improved.
In one embodiment, the step S101 includes the following sub-steps: detecting whether an included angle between the first direction and the gravity direction is smaller than a first preset included angle or not; the first direction is a direction which is perpendicular to a plane corresponding to a screen of the terminal device and points to a backboard of the terminal device from the screen of the terminal device. At this moment, the above-mentioned screen that detects terminal equipment places up includes: when detecting that the included angle between the first direction and the gravity direction is smaller than a first preset included angle, determining that the screen of the terminal device is placed upwards.
Fig. 5 is a schematic view showing a first direction according to an exemplary embodiment, and fig. 6 is a schematic view showing a cross section of a terminal device placed on a table top according to an exemplary embodiment, where as shown in fig. 5 and 6, the table is placed on a horizontal plane, the terminal device is placed on the table top with a screen of the terminal device facing upward, where an angle between the first direction and a direction of gravity is 90 °, and when the terminal device is taken up in the direction shown in fig. 7 or in the direction shown in fig. 8, where the screen of the terminal device faces upward, where an angle between the first direction and the direction of gravity is acute; as shown in fig. 9 and 10, when the terminal device is lifted in the direction shown in fig. 9 and 10, the screen of the terminal device faces downward, and the angle between the first direction and the gravity direction is obtuse in both modes. Therefore, whether the screen of the terminal device faces upward may be detected based on an included angle between the first direction and the gravity direction, and based on the scenarios shown in fig. 5 to 10, the first preset included angle may be 90 °, that is, when it is detected that the included angle between the first direction and the gravity direction is smaller than 90 °, it is determined that the screen of the terminal device faces upward.
For example, an acceleration sensor may be preset in the terminal device, and the acceleration value in each direction is obtained by the acceleration sensor; calculating a gravity acceleration value through the acceleration values in all directions; then, acquiring an acceleration value corresponding to the first direction through an acceleration sensor; and acquiring an included angle value between the first direction and the gravity direction according to the gravity acceleration value and the acceleration value corresponding to the first direction.
The included angle value between the first direction and the gravity direction can be obtained through the trigonometric function relationship, the gravity acceleration value and the acceleration value corresponding to the first direction, the calculation method is the same as that in the related technology, and details are not repeated here.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: whether the screen of the terminal equipment faces upwards is judged by detecting the plane corresponding to the screen perpendicular to the terminal equipment and the included angle between the direction of the screen of the terminal equipment pointing to the backboard of the terminal equipment and the gravity direction, and the judgment accuracy can be improved.
In one embodiment, the detecting whether the screen of the terminal device moves towards the direction facing the user includes the following sub-steps: detecting whether an included angle between the second direction and the gravity direction is smaller than a second preset included angle or not; the second direction is a direction which is parallel to a side frame of a screen of the terminal equipment and points to the bottom of the terminal equipment from the top of the terminal equipment; at this time, the detecting that the screen of the terminal device moves towards the direction facing the user includes the following sub-steps: and when detecting that the included angle between the second direction and the gravity direction is smaller than a second preset included angle, determining that the screen of the terminal equipment moves towards the direction facing the user.
Fig. 11 is a schematic diagram illustrating a second direction according to an exemplary embodiment, and fig. 12 is a schematic diagram illustrating a cross section of a terminal device placed on a desktop according to an exemplary embodiment, where as shown in fig. 11 and 12, the desk is placed on a horizontal plane, the terminal device is placed on the desktop, and a screen of the terminal device is placed upward, where an angle between the second direction and a direction of gravity is 90 °, and as shown in fig. 13, when the screen of the terminal device moves toward a direction facing a user, an angle between the second direction and the direction of gravity is an acute angle; as shown in fig. 14, when the screen of the terminal device moves in a direction away from the user, the angle between the second direction and the gravity direction is an obtuse angle. Therefore, whether the screen of the terminal device moves towards the direction facing the user may be detected based on an angle between the second direction and the gravity direction, and based on the scenarios shown in fig. 11 to 14, the second preset angle may be 90 °, that is, when it is detected that the angle between the second direction and the gravity direction is smaller than 90 °, it is determined that the screen of the terminal device moves towards the direction facing the user.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: whether the screen of the terminal equipment moves towards the direction facing the user or not is judged by detecting the side frame parallel to the screen of the terminal equipment and the included angle between the direction pointing to the bottom of the terminal equipment from the top of the terminal equipment and the gravity direction, and the judgment accuracy can be improved.
In one embodiment, to increase the fault tolerance, a positive offset may be given to 90 ° in the above embodiment, so that the determined second predetermined included angle is greater than 90 °, for example: the positive offset is 10 °, and the two preset included angles are 100 °.
The offset can be preset, and can also be optimized according to later debugging, so that the finally determined second preset value is more accurate, and the result of finally judging whether the screen of the terminal equipment moves towards the direction facing the user is more accurate.
If the user accidentally touches the terminal device, and the screen of the terminal device is moved towards the direction facing the user, at this time, if the face unlocking function is triggered, the user experience is poor, and therefore, in one embodiment, when it is detected that the included angle between the second direction and the gravity direction is smaller than a second preset included angle, it is determined that the screen of the terminal device is moved towards the direction facing the user, including the following sub-steps A1-A2:
in the step A1, when it is detected that the included angle between the second direction and the gravity direction is smaller than a second preset included angle, it is detected whether the change value of the included angle between the second direction and the gravity direction is greater than a third preset included angle within a preset time period.
In the step A2, when the fact that the change value of the included angle between the second direction and the gravity direction is larger than a third preset included angle in the preset time period is detected, the screen of the terminal device is determined to move towards the direction facing the user.
The screen of the terminal device can be determined to move towards the direction facing the user based on the acquired size of the change value of the included angle between the second direction and the gravity direction in the preset time period, and whether the terminal device is taken up by the user can also be determined.
For example, an acceleration sensor may be preset in the terminal device, and the acceleration value in each direction is obtained by the acceleration sensor; calculating a gravity acceleration value through the acceleration values in all directions; then, acquiring an acceleration value corresponding to the second direction through an acceleration sensor; and acquiring an included angle value between the second direction and the gravity direction according to the gravity acceleration value and the acceleration value corresponding to the second direction.
The angle between the second direction and the gravity direction can be obtained through the trigonometric function relationship and the gravity acceleration value and the acceleration value corresponding to the second direction, the calculation method is the same as that in the related art, and details are not repeated here.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: whether the screen of the terminal equipment moves towards the direction facing the user or not is judged according to the size of the change value of the included angle between the second direction and the gravity direction in the preset time period, and the judgment accuracy can be improved.
