Below with reference to accompanying drawing, the unlock method according to the mobile terminal of the embodiment of the present invention is described.
A kind of unlock method of mobile terminal comprises the following steps: the target object that a movement is provided in the release interface of mobile terminal; Obtain the current location of track that the user inputs in the release interface of mobile terminal and mobile target object, wherein, the residing instantaneous position of target object when the current location of target object is user's input trajectory; Minor increment between the track of calculating user input and the current location of target object; Judge whether this minor increment is less than default distance threshold; And if the judgement minor increment be less than distance threshold, mobile terminal carries out release.
Fig. 1 is the process flow diagram of the unlock method of mobile terminal according to an embodiment of the invention.
As shown in Figure 1, according to the unlock method of the mobile terminal of the embodiment of the present invention, comprise the steps.
Step S101: the target object that a movement is provided in the release interface of mobile terminal.
In one embodiment of the invention, when design release interface, can provide a target object moved freely, the translational speed of this target object and moving range can be adjusted according to demand.For example, the release interface of mobile terminal is the lake of a slice beauty, in lake, has a fish freely moving about; Perhaps, the release interface is the boundless and indistinct grassland of a slice, and the courser of a Pentium is arranged on grassland, etc.
In an embodiment of the present invention, mobile terminal can be the hardware device that mobile phone, panel computer, personal digital assistant, e-book etc. have various operating systems.Can adopt any operating system in this hardware device, such as Android, iPhoneOS system etc.
Step S102: obtain the current location of track that the user inputs in the release interface of mobile terminal and mobile target object, wherein, the residing instantaneous position of target object when the current location of target object is user's input trajectory.
Particularly, when the user needs release, a track of input on the release interface, after end of input, mobile terminal can by as touch sensor etc. obtain the track that the user inputs.
In addition, the motion track of target object can be preset, thus, according to time and this predetermined motion track of user's input trajectory, the current location of mobile target object can be easily obtained.
Step S103: the minor increment between the track of calculating user input and the current location of target object.
Particularly, acquisition for mobile terminal, after the track of user's input, can calculate the equation of locus of this user's input, can easily calculate thus the current location of target object and the minor increment between this track.
Step S104: whether the minor increment that judgement calculates is less than default distance threshold.
Step S105: if the judgement minor increment is less than distance threshold, mobile terminal carries out release.
In an embodiment of the present invention, the track of user's input and the relative distance between the moving target object are less than certain threshold value and just can realize release, prevent well maloperation and release thus.
For example, according to above-mentioned example, if the distance between the fish of the track of user's input and movement is less than certain threshold value, mobile terminal carries out release.Perhaps, if the distance between the courser of the track of user's input and Pentium is less than certain threshold value, mobile terminal carries out release.
In addition, it should be noted that, also can on the release interface, show the track of user's input in real time, thus, the user can understand the distance between this track and target object in simple, intuitive ground, thus the guides user input trajectory, in order to realize release.
According to the unlock method of the mobile terminal of the embodiment of the present invention, realize unlocking screen by the track of judgement user input and the relative distance between target object, easy and simple to handle, realize simply, can prevent well maloperation and release.And the track of user input is fixing, can prevent regular release and the screen injury that causes, increase the interest that the user uses mobile terminal simultaneously, embody better the intelligent of mobile terminal, realize better human-computer interaction.
Fig. 2 is the process flow diagram of the unlock method of mobile terminal according to an embodiment of the invention.
As shown in Figure 2, according to the unlock method of the mobile terminal of the embodiment of the present invention, comprise the steps.
Step S201: the target object that a movement is provided in the release interface of mobile terminal.
Step S202: obtain the current location of track that the user inputs in the release interface of mobile terminal and mobile target object, wherein, the residing instantaneous position of target object when the current location of target object is user's input trajectory.
Step S203: the minor increment between the track of calculating user input and the current location of target object.
Step S204: whether the minor increment that judgement calculates is less than default distance threshold.
The specific implementation process of above-mentioned steps S201 to S204 can, referring to the description of step S101 to S104, be introduced herein no longer in detail.
Step S205: if the minor increment that judgement calculates is less than default distance threshold, according to the type of target object, generate corresponding animation, realize release simultaneously.
For example, the track of inputting as the user meets required distance, and screen produces a net, presents the effect of fishing, realizes release; Perhaps, occur immediately on screen that a railing stops moving on of horse, realizes release simultaneously.Thus, further improve the interest that the user uses mobile terminal.
Step S206: if the minor increment that judgement calculates is not less than default distance threshold, point out in the release of release interface display.
For example, if the hypertelorism between the current location of the fish of the track of user's input and movement surpasses predetermined distance threshold, mobile terminal is not carried out to release, point out the user to re-enter track to re-start release simultaneously.
According to the unlock method of the mobile terminal of the embodiment of the present invention, the type simulation according to target object when realizing release goes out certain animation effect, further increases the interest that the user uses mobile terminal.
Describe the mobile terminal according to the embodiment of the present invention in detail below in conjunction with accompanying drawing.
