To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
All other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Embodiment one
Below in conjunction with Fig. 1, Fig. 1 is a kind of flow chart of function triggering method provided by the embodiments of the present application, after the application
The executing subject of continuous any embodiment is a kind of intelligent mobile terminal, receives being used for for user's drafting by touch display screen
The track pattern of function triggering, it should be noted that touch display screen can also be based on unification each tracing point is presented from the background
The coordinate of rectangular coordinate system, specifically includes the following steps:
S101: the actual path pattern of input is received；
This step is intended to receive externally input actual path pattern, which can be user and directly use hand
Finger mobile drafting on capacitance plate obtains, and can also draw to obtain by dedicated writing pencil, herein and be not specifically limited.
S102: it is suitable by drawing that actual path pattern is obtained by way of line direction between constantly calculating each adjacent track point
The direction value sequence of sequence arrangement, and as actual direction value sequence；
On the basis of S101, this step is intended between the side connected each tracing point for forming the actual path pattern
It is arranged to value by drawing order, to obtain one and the unique corresponding direction value sequence of the actual path pattern that receives,
The direction value sequence being calculated by the actual path pattern is known as actual direction value sequence herein.Wherein, every two is adjacent
Tracing point, which is connected, can obtain a track line segment, and each track line segment can based on the different directions value that same coordinate system obtains
To be used to describe the direction change of the actual path pattern, and obtained direction value sequence can uniquely represent the actual path figure
Case, therefore the application is in fact provided and a kind of is differentiated between two patterns with the presence or absence of consistency based on pattern direction situation of change
Method.Specifically, every can be used to connect obtained track line segment under the rectangular coordinate system under identical rectangular coordinate system
Slope value or angle value as its corresponding direction value, some auxiliary parameters or customized ginseng can also be combined on this basis
Number mode obtains direction value.
The sequencing that the drawing order of track pattern, that is, each tracing point coordinate determines, for example, a track pattern by
When 100 tracing point compositions, the 1st tracing point is exactly the first tracing point obtained by drawing order, and the 2nd tracing point is exactly phase
Adjacent next tracing point with the 1st tracing point, and so on to the 100th tracing point, it is also necessary to explanation, this step may be used also
To begin to the calculating to the partial traces click-through line direction value for having determined coordinate while receiving actual path pattern, i.e.,
The calculating process of direction value is carried out with drawing process is synchronous, can accelerate entire identification process.
Also it should be noted that the mode for constantly calculating line direction between each adjacent track point of this step description refers to from the
1 tracing point starts, and direction value is constantly calculated in a manner of the point of adjacent track two-by-two, such as first calculating is exactly the 1st rail
The direction value of line between mark point and the 2nd tracing point, what is next calculated is exactly to connect between the 2nd tracing point and the 3rd tracing point
The direction value of line, and so on to line between the 99th tracing point and the 100th tracing point direction value, will eventually get 99
Different track line segments, that is, can have 99 direction value.
S103: whether all directions value that is arranged in actual direction value sequence of judgement with same sequence is arranged in standard side
All directions value into value sequence is consistent；
On the basis of S102, this step be intended to judge all directions value that is arranged in actual direction value sequence whether with
It is consistent that same sequence is arranged in all directions value in reference direction value sequence, with seen according to judging result whether meet it is preset
Function trigger condition.Wherein, reference direction value sequence is by pre-rendered obtained standard trajectory pattern through identical calculations step
Obtained direction value queue, therefore, this step is really based on the difference between direction value to actual path pattern and standard trajectory
Whether with uniformity judged between pattern.
It should be noted that in view of the existing error of practical drawing process is (even if the same pattern is successively drawn twice
System can also have differences), it is described herein it is consistent not only refer to complete identical, be also in certain allowable range of error
It is approved, also may be considered that two track patterns are consistent, be it is identical, meet consistency checking.Practical operation
Cheng Zhong, the allowable range of error can be adjusted flexibly according to required precision, can also be according to numerous sample data COMPREHENSIVE CALCULATINGs
A more reasonable error threshold is obtained, repeats the probability drawn to reduce user in the case where precision meets the requirements.
S104: it calls function chain corresponding with standard trajectory pattern to fetch and triggers corresponding function；
This step establish the judging result in S103 be all directions value that is arranged in actual direction value sequence with identical
Sequence be arranged in all directions value in reference direction value sequence it is consistent on the basis of, therefore can call and standard trajectory pattern phase
Corresponding function chain fetches the corresponding function of triggering, such as opens some application program (camera, music, flashlight etc.),
Execute a certain system operatio etc. (screen locking, unlock, shutdown etc.).It should also be noted that, can also be according to the actual path
The interface level difference that pattern is plotted in executes different operations, such as draws on the locking screen interface presented when equipment does not unlock
One track pattern, and consistency checking passes through, it is assumed that the track pattern when a payment interface should be opened after being verified,
Also unlocking information can be requested to user because of not unlocking, it is true to prevent from directly stealing in the case where the track pattern is pried through
The wealth of positive user.Certainly, if the corresponding function of the track pattern is to open the conventional small tool such as flashlight, boundary can also be ignored
The influence of surface layer grade further can also be by defining the authority information of each track pattern to determine whether negligible layer
The influence of grade.
S105: reporting an error or does not do any response.
This step establish the judging result in S103 be all directions value that is arranged in actual direction value sequence with identical
On the basis of all directions value that sequence is arranged in reference direction value sequence is not quite identical, then mistake can be had input because of detecting
The return error information of track pattern selectivity accidentally does not directly do any response, these can flexibly set.
Further, in order to reduce user with regard to the drafting number of same error track pattern, promotion user draws success rate,
The wrong track pattern once inputted can also be shown in a certain position of display screen, promoted to give user's mistake, i.e.,
The track pattern inputted again should be the new track pattern for being different from the mistake track pattern, to prevent from not finding mistake
Same wrong track pattern is drawn repeatedly when point.At the same time it can also show multiple wrong track patterns simultaneously, do not do herein
It is specific to limit, it can be according to particular/special requirement flexible choice that may be present under all actual conditions.
Based on the above-mentioned technical proposal, a kind of function triggering method provided by the embodiments of the present application is different from existing based on figure
As recognition principle judge between the track pattern actually entered and preset standard trajectory pattern whether consistent method, the application base
The direction of the track line segment connected in track pattern by each tracing point carries out the mode of across comparison to judge between the two
Consistency, the similarity calculation of image is switched to the calculating of direction value, the latter can be directly based upon the coordinate of each tracing point easily
It calculates, without calculating based on general image by complicated algorithm as the former, can obviously reduce computation complexity, into
And the system resource quantity for needing to occupy is reduced, it is more suitably applied to the intelligent mobile terminal of various lightweight, user uses body
It tests more preferably.

S406: it when the sequence direction value difference being calculated is less than default allowable error, calls and standard trajectory pattern
Corresponding unlocking function link, to be unlocked using the unlock instruction generated according to unlocking function link to equipment.
Embodiment five
On the basis of above-mentioned each embodiment, the present embodiment combines specific unlock scene, gives a kind of specific
Implementation:
Central principle: user first prestores a track drafting, and program records the main drafting in its drawing process when drafting
The sequence in direction and direction.When user needs to unlock, the track similar with track is prestored is drawn, record is drawn in input
Main drafting direction in the process, and being compared in order with the direction value prestored, if the direction sequence of track drafting and pre-
The direction sequence for depositing track is identical, then is judged to passing through, otherwise is judged to not passing through.
Specific track drawing process explanation: in a program, can preset several specific angle values, such as above,
Under, left and right, upper left, upper right, lower-left, bottom right, point (directionless) etc., in practical drawing process, the angle recognized can first quilt
It is similar arrive immediate predetermined angle, then other judgements are done, error is eliminated with this, more complexities of angle initialization are more
Height, but precision is poorer, and vice versa.In drawing process, program can be come with a frequency specially to the current finger of user
The point at place carries out coordinate record, and compares a coordinate to obtain the angle value of track at this time, and angle value can be arrived by approximation
Predetermined angle；Program can set a fault-tolerant threshold value, if the number that some angle value continuously occurs has been more than the fault-tolerant threshold value,
It can be recorded, on the contrary then will not be recorded, this measure is used to eliminate direction change process bring error in user's operation；User's
Drawing process can divide a plurality of curve to be drawn, and not require to settle at one go, if track drafting interrupts, next angle value is not
It will be considered that and upper one is continuously, even if the angle value of front and back is consistent.User input interrupt be more than certain predetermined when
The method of the manual executive termination input of long or user, then it is assumed that input terminates.
For the termination input method that user executes, this programme with no restrictions, can be the movement for marking screen, or fast
Speed double-clicks screen, or clicks the termination input button on screen, as long as required progress when input trajectory can be different from
Operation, all can serve as terminate input method.
By this programme be used for mobile phone screen unlock etc. users' self-protection unlock behavior when the specific scheme is that
Step 1: prestoring track.User needed first to preset a desired trajectory before using this unlock scheme, as
Unlock foundation when unlock every time.User is come in recording track drawing process when drafting prestores track using above method
Angle value, until user terminates to input.After end of input, program prestores the angle value sequence of track under saving；
Step 2: confirmation track.User can be required to draw once identical track again, and phase is used in track drafting
With recognition methods record angle value, if the angle value sequence that user this time records in drawing process was prestored with the last time
Angle value sequence it is identical, then this password comes into force, and otherwise password will not come into force, and may require that user reattempts to；
Step 3: track unlocks.When user attempts to carry out unlocking screen to touch screen terminal, may require that user draw with it is pre-
If the identical track in track, identification process when track drafting is identical as process when confirmation track, when user this time drew
The angle value sequence recorded in journey is identical as the angle value sequence prestored, then is judged to passing through, and is otherwise judged to not passing through.
If user needs to modify desired guiding trajectory, needs first to carry out a track unlock, prestore rail by then continuing to execute
Mark modifies the track prestored with the step of track is confirmed, after coming into force, unlock authority is changed to the angle of the last desired guiding trajectory
Angle value sequence.
Compared with conventional approach, scheme provided in this embodiment is had the advantages that
1, safety: assuming that when realizing the program, program can identify direction in 8 altogether, there is 5 directions in the track of drafting
(being equivalent to 5 passwords) then co-exists in 85=32768 kind arrangement possibility, compared to the gesture solution of 3 × 3 points of mainstream instantly
Lock mode (is once known as the unlock of 3 × 3 gestures), streaks 5 points (being equivalent to 5 passwords), co-exists in 9 × 8 × 7 × 6 × 5=
The complexity of 15120 kinds of possibility, password is unlocked higher than 3 × 3 gestures.According to calculating it is found that after Password Length is more than 3,
Arrangement sum of the invention will be greater than 3 × 3 gestures and unlock, and digit is longer, complexity difference it is higher, i.e., encryption is more
It is good, and theoretically there is no maximum Password Lengths to limit by the present invention；
2, user experience: in addition to safety, the user experience that unlock is is can be improved in the present invention.Due to only relying on track side
To as unlock foundation, some drawbacks can be unlocked to avoid 3 × 3 gestures, comprising: fixed input position (is easy accidentally touching mistake
Point, will necessarily show track when accidentally touching sliding to reduce), must single stepping in place (more complex password draw it is difficult, easily
Interrupt error；Make snooping to drafting movement after, it is easier to try out correct combination), password maximum length limitation (limit the solution
The highest complexity of lock mode) etc., user can be in screen any position track drafting, and the limitation of fixed point, is not required to yet
It settles at one go, as long as direction sequence matches, operation is simpler, more meets memory and the input habit of user；
3, the balance of calculation amount and precision: the track similarity for comparing more similar no aided location judges unlocking manner,
Present invention only requires the slope for judging track, does not need to introduce complicated mathematical model, compare using image recognition and machine
For scheme of the device learning algorithm to carry out track characteristic comparison, the present invention is more suitable for being actually introduced into mobile terminal, when use
Too many hardware computing resource will not be occupied, and due to using lines to draw direction as basis of characterization, meet that user is practical to draw
Memory habit when processed, therefore can achieve preferable accuracy of identification, and be easy to user's study and understand its operating method.
Because situation is complicated, it can not enumerate and be illustrated, those skilled in the art should be able to recognize according to the application
The basic skills principle combination actual conditions of offer may exist many examples, in the case where not paying enough creative works,
It should within the scope of protection of this application.
