Detailed Description
The application provides a screen unlocking method, a device, a storage medium and a mobile terminal, which are used for making the purpose, the technical scheme and the technical effect of the application more clear and clear, and the application is further described in detail below, wherein the specific embodiments are only used for explaining the application and are not used for limiting the application.
Referring to fig. 1, fig. 1 is a flow chart of a screen unlocking method according to an embodiment of the present application, which is applied to a mobile terminal, and the specific flow of the screen unlocking method may be as follows:
s101: and when the display screen is in a locked state, receiving a screen unlocking instruction.
The mobile terminal comprises a display screen, and in order to ensure the safety of information stored in the mobile terminal, the mobile terminal can lock the display screen of the mobile terminal when receiving a screen locking instruction, and in order to ensure that a user of the mobile terminal can normally acquire the information stored in the mobile terminal, the mobile terminal can unlock the display screen when receiving a screen unlocking instruction after locking the display screen, namely, the running state of the display screen comprises a locking state and an unlocking state.
It should be noted that, the above screen locking instruction is used to instruct the mobile terminal to lock the display screen, and the screen locking instruction may be triggered by the user to obtain by executing a preset operation. The screen unlocking instruction is used for indicating the mobile terminal to unlock the display screen, and the screen unlocking instruction can be triggered by a user to acquire through executing preset operation. The preset operation may be a click operation, a sliding operation, a touch operation, a key operation, or other operations in practical applications.
S102: and determining the target number of the target touch blocks and the display position of each target touch block according to the screen unlocking instruction.
In one embodiment, to determine the target number of target touch blocks, the step S102 may specifically include:
S1021, acquiring the historical number of the target touch block.
The historical number may refer to a target number determined when the mobile terminal is last triggered to unlock the screen.
S1022, determining the target number of the target touch blocks from a preset number library according to the historical number.
The preset number library may include a plurality of preset numbers, for example, 1,3, 5, 6, 9, etc., and the preset number library may be a preset number sequence, where each preset number may correspond to a serial number, and the serial number may be obtained by sorting the plurality of preset numbers in the preset number library according to a preset rule (for example, a size sequence).
Specifically, after the mobile terminal obtains the historical number of the target touch block, the preset number of the sequence number, which is located at the position behind the serial number of the historical number, in the preset number sequence may be used as the target number of the target touch block when the unlocking screen is triggered at this time. In addition, in the specific implementation, the preset number with the smallest serial number in the preset number sequence can be preset to be located at the position behind the preset number with the largest serial number, so that the target number of the target touch block can be circularly switched in the preset number sequence when the mobile terminal is triggered to unlock the screen each time, and a changeable unlocking interface can be provided to improve the interestingness of screen unlocking.
In some alternative embodiments, the mobile terminal may also randomly select an integer from a preset value range (for example, 1 to 10) to obtain the target number of the target touch pieces.
In a specific embodiment, before the step S102, the method may further include:
step A: and when the display screen is in an unlocking state, receiving an unlocking setting instruction.
And (B) step (B): and displaying an unlocking setting interface on the display screen according to the unlocking setting instruction.
Step C: and acquiring a plurality of setting schemes input by a user through an unlocking setting interface, wherein each setting scheme comprises at least one target touch block and a display position of each target touch block.
Different setting schemes can have different numbers of target touch blocks, and the display position of each target touch block in the setting scheme can be set by a user according to own use habits and favorites.
Specifically, when a user needs to input a new setting scheme or modify an input setting scheme, the mobile terminal can be triggered to generate an unlocking setting instruction through operations such as pressing a key, touching, clicking and the like, so that the mobile terminal can enter an unlocking setting interface. And, the user can input a plurality of setting schemes on the unlocking setting interface through a touch screen mode. For example, when a user inputs a certain setting scheme on the unlocking setting interface, at least one graph (for example, a rectangle) can be drawn on the unlocking setting interface by clicking with one hand, so as to obtain at least one target touch block contained in the setting scheme, wherein one graph is one target touch block, and then the user can adjust the display position of the corresponding target touch block on the unlocking setting interface by clicking and dragging each target touch block.
Further, in order to determine the display position of each target touch block, S102 may specifically include:
S1023, determining a target setting scheme from a plurality of setting schemes according to the target quantity.
Specifically, the mobile terminal may set a setting scheme including a target number of target touch blocks among the plurality of setting schemes as the target setting scheme. For example, if the number of targets is 3, the target setting scheme may also include three target touch blocks.
S1024, determining the display position of each target touch block according to the target setting scheme.
Specifically, when the above-mentioned target touch block is a geometric polygon, the display position of the target touch block may include coordinates of respective top corners of the target touch block, for example, the target touch block is a rectangle, and the display position of the target touch block may include coordinates of 4 top corners of the rectangle of the target touch block. In some embodiments, the target touch pad may also be an icon, and correspondingly, the display position may also be coordinates of a center point of the target touch pad icon.
S103: and generating an unlocking interface according to the display position, wherein the unlocking interface comprises target touch blocks with target quantity.
Specifically, the mobile terminal may add a corresponding target touch block at a display position of a preset background picture to obtain the unlock interface, and the preset background picture may be preset by a user or default by a system. For example, as shown in fig. 2 (1) and (2), the unlock interface 20 may include 2 target touch pieces 21/22.
S104: and displaying an unlocking interface on the display screen so that a user can unlock the display screen through the unlocking interface.
Specifically, the target touch blocks with the target number in the unlocking interface are used for forming a screen unlocking pattern, and the screen unlocking pattern is used for guiding a user to perform correct unlocking operation on the unlocking interface so as to unlock the display screen.
In this embodiment, since the number of targets and the display positions of the target touch blocks determined each time the mobile terminal is triggered to unlock the screen are variable, the corresponding unlock interface and the correct unlock operation are also variable, so that the problem of user privacy disclosure caused by the fact that the correct unlock operation is fixed can be avoided.
In a specific embodiment, as shown in fig. 3, after S104, the method may further include:
s105, when the touch operation of the user on the unlocking interface is detected, a contact track corresponding to the touch operation is obtained.
Specifically, the contact track may be composed of a plurality of contacts, and the plurality of contacts may be a plurality of touch points of the user on the unlocking interface, which are sequentially recorded by the mobile terminal according to time sequence when the user performs a touch operation on the unlocking interface. The touch operation may be a sliding type touch operation, for example, touch sliding, and one touch operation corresponds to one touch track, for example, when the user performs touch sliding on the unlock interface, if the user finger leaves the unlock interface, the user may be considered to end the touch operation.
S106, unlocking the display screen according to the contact track and the display position.
As shown in fig. 3, the step S106 may specifically include:
S1061, determining contacts corresponding to each vertex angle point from the contact track according to the display position to obtain contact combinations, wherein each contact combination corresponds to one vertex angle point.
Specifically, the target touch block may be a geometric figure (for example, a geometric polygon such as a triangle, a square, a rectangle, a regular pentagon, etc.), and has at least one vertex point, and accordingly, the display position of the target touch block may include an abscissa and an ordinate of each vertex point of the target touch block, and the S1061 may specifically include: and classifying the contacts with the same abscissa as that of the vertex angle points or the same ordinate as that of the vertex angle points in the contact track into a group to obtain corresponding contact combinations.
For example, as shown in (1) of fig. 2, the unlocking interface 20 includes 2 rectangular target touch blocks 21/22 thereon, wherein the target touch block 21 has four corner points a/B/C/D and the target touch block 22 has four corner points E/F/G/H. The contact trace L1 is input in a touch screen manner when the user unlocks the display screen through the unlocking interface 20. The contact track L1 has two contacts a/B with the same abscissa as the abscissa of the vertex point a, and two contacts C/D with the same ordinate as the ordinate of the vertex point a, that is, the contact combination corresponding to the vertex point a is { contact a, contact B, contact C, contact D }, and so on, the contact combination corresponding to the vertex point B/C/D/E/G/H is { contact E, contact F, contact C, contact D }, { contact a, contact B, contact G, contact H }, { contact E, contact F, contact G, contact H }, { contact i, contact j, contact k, contact L, contact q }, { contact m, contact n, contact k, contact L, contact r }, { contact i, contact j, contact o, contact p, contact q } and { contact m, contact n, contact o, contact p, contact r }, respectively.
It is understood that, for the same vertex point, if there is neither a contact point whose abscissa is the same as that of the vertex point nor a contact point whose ordinate is the same as that of the vertex point in the contact point track, the contact point combination corresponding to the vertex point may be considered as empty, that is, there is no contact point.
S1062, judging whether four contacts exist in each contact combination, wherein an area surrounded by the four contacts comprises corresponding vertex angle points, if yes, executing S1063, and if not, not processing.
Specifically, for the same vertex point, when the contact point combination corresponding to the vertex point includes at least one contact point whose abscissa is the same as the abscissa of the vertex point and whose ordinate is greater than the ordinate of the vertex point, at least one contact point whose abscissa is the same as the abscissa of the vertex point and whose ordinate is less than the ordinate of the vertex point, at least one contact point whose ordinate is the same as the ordinate of the vertex point and whose abscissa is less than the abscissa of the vertex point, and at least one contact point whose ordinate is the same as the ordinate of the vertex point and whose abscissa is greater than the abscissa of the vertex point, it may be determined that four contact points exist in the contact point combination corresponding to the vertex point, and an area enclosed by the four contact points includes the vertex point. For example, as shown in (1) of fig. 2, for the corner point a, when there are simultaneously a contact point a having an abscissa identical to the abscissa of the corner point a and an ordinate larger than the ordinate of the corner point a, a contact point b having an abscissa identical to the abscissa of the corner point a and an ordinate smaller than the ordinate of the corner point a, a contact point c having an ordinate identical to the ordinate of the corner point a and an abscissa smaller than the abscissa of the corner point a, and a contact point d having an ordinate identical to the ordinate of the corner point a and an abscissa larger than the abscissa of the corner point a in the contact point combination { contact point a, contact point b, contact point c, contact point d } corresponding to the corner point a, four contact points a/b/c/d exist, and the area abcd formed by the four contact points a/b/c/d encloses the corner point a.
And if each vertex angle point in all vertex angle points can meet that four contacts exist in the corresponding contact combination, and the area surrounded by the four contacts contains the vertex angle point, executing the subsequent step S1063 to unlock the display screen, otherwise, continuing to keep locking the display screen.
For example, as shown in fig. 3, since each of all the top corner points a/B/C/D/E/F/G/H on the unlocking interface 20 satisfies that four contacts exist in the corresponding contact combinations, and the area enclosed by the four contacts includes the top corner point, the mobile terminal may then execute the subsequent step S1063.
For another example, as shown in (2) of fig. 2, when the user inputs the contact trace L2 in a touch screen manner when unlocking the display screen through the unlocking interface 20, there is a contact a ' having an abscissa identical to an abscissa of the vertex point a in the contact trace L2, and there are two contacts C '/D ' having an ordinate identical to an ordinate of the vertex point a, that is, the contact combination corresponding to the vertex point a is { contact a ', contact C ', contact D ' }, and so on, the contact combination corresponding to the vertex point B/C/D/E/F/G/H is { contact E ', contact C ', contact D ' }, { contact a ', contact G ', contact H ' }, { contact E ', contact G ', contact H ' }, { contact k ', contact L ' }, contact o ', contact p ' }, and { contact o ' }, and { contact p ' }, respectively. In this case, since each of the corner points a/B/C/D/E/F/G/H of the unlocking interface 20 does not satisfy the existence of four contacts in the corresponding contact combinations, and the area enclosed by the four contacts includes the corner point, the mobile terminal will not perform the subsequent step S1063, but will continue to lock the display screen.
In a specific embodiment, in order to increase the complexity of the contact track input when the user correctly unlocks, so that the touch screen unlocking manner is not easily mastered by other people, S1062 may specifically include: judging whether four contacts exist in each contact combination, wherein the area surrounded by the four contacts is a square area or a rectangular area and comprises corresponding vertex angles, if so, executing S1063, and if not, not processing.
Specifically, for the same vertex point, when the contact point combination corresponding to the vertex point includes a contact point 1 whose abscissa is the same as the abscissa of the vertex point and whose ordinate is greater than the ordinate of the vertex point, a contact point 2 whose abscissa is the same as the abscissa of the vertex point and whose ordinate is less than the ordinate of the vertex point, a contact point 3 whose ordinate is the same as the ordinate of the vertex point and whose abscissa is less than the abscissa of the vertex point, and a contact point 4 whose ordinate is the same as the ordinate of the vertex point and whose abscissa is greater than the abscissa of the vertex point, and an area enclosed by the four contact points 1/2/3/4 after the contact points 1-contact points 3-contact points 2-contact points 4 are sequentially connected in order is a square area, it can be determined that the area enclosed by the four contact points 1/2/3/4 corresponding to the vertex point is a square area, and the vertex point is included.
And if each vertex angle point in all vertex angle points can meet that four contacts exist in the corresponding contact combination, and the area surrounded by the four contacts is a square area and contains the vertex angle point, executing the subsequent step S1063 to unlock the display screen, otherwise, continuing to keep locking the display screen.
S1063, unlocking the display screen.
Compared with the prior art, the screen unlocking method in the embodiment is applied to the mobile terminal, the mobile terminal comprises a display screen, the screen unlocking method is used for receiving screen unlocking instructions when the display screen is in a locked state, determining the target number of target touch blocks and the display position of each target touch block according to the screen unlocking instructions, generating an unlocking interface according to the display positions, wherein the unlocking interface comprises the target number of target touch blocks, and displaying the unlocking interface on the display screen so that a user can unlock the display screen through the unlocking interface, and therefore when the screen is unlocked, the display positions and the number of target touch pieces on the unlocking interface can be changed, so that the input contact track is not fixed and unchanged when the screen is correctly unlocked, and the problems that the touch screen unlocking mode is fixed singly and is easy to be mastered by others, and privacy of the user is leaked are avoided.
