Embodiment
The invention provides a kind of accelerometer that utilizes and realize the method and system that mobile terminal is unblanked, below embodiments of the invention are by reference to the accompanying drawings described in detail.
For a kind of accelerometer that utilizes provided by the invention, realize the method step process flow diagram that mobile terminal is unblanked as described in Figure 1, as shown in the figure, said method comprising the steps of:
S1, on described mobile terminal, set an accekeration for the threshold value of unblanking in advance.
The present invention is on the mobile terminal being based upon with accelerometer, by the measured accekeration of accelerometer, whether exceed the default threshold value of unblanking and judge whether user has triggered the event of unblanking, therefore when using the method to unblank for mobile terminal, first need dual lock threshold value to arrange.
Can expect, arranging of dual lock threshold value can be an accekeration of system default, can be also user according to the threshold value of unblanking that need to arrange voluntarily of oneself,
S2, accelerometer are measured the accekeration of mobile terminal in real time, and by the accekeration recording and the threshold of unblanking of presetting, whether the accekeration that judgement records exceeds the threshold value of unblanking, if exceed, judge that mobile terminal triggers the event of unblanking, and carries out next step; Otherwise proceed judgement.
Accelerometer is measured the acceleration of mobile terminal in real time, when user sends whipping action to mobile terminal, the suffered acceleration of mobile terminal can increase suddenly in mobile terminal whipping direction, the accekeration that accelerometer makes progress to the party is measured, and this accekeration and the default threshold value of unblanking are compared, when this accekeration exceeds default unblanking during threshold value, judge the action that action that user this time sends is unblanked as triggering mobile terminals, otherwise accelerometer continues the accekeration of mobile terminal to measure.
S3, control mobile terminal are unblanked.
If accelerometer determines the acceleration of mobile terminal and exceeds default unblanking and during threshold value, control mobile terminal and unblank, thereby just realize user only mobile terminal is sent to whipping action can triggering mobile terminals auto-unlocking.
For the action of sending according to user more accurately, mobile terminal is unblanked, prevent from judging by accident triggering the event of unblanking, described step S2 also comprises:
When accelerometer, judge measured in one direction accekeration and exceed the threshold value of unblanking, and in the given time on the reverse direction of this direction measured accekeration exceed equally the threshold value of unblanking, judge that the accekeration record exceeds the threshold value of unblanking.
Owing in one direction accekeration being judged, easily produce the erroneous judgement that triggers the event of unblanking, therefore in the present embodiment, when accelerometer, judge the accekeration of all measuring on two reverse directions at same level line and exceed the threshold value of unblanking, and the time interval that two reverse direction accekerations in the same horizontal line exceed the threshold value of unblanking is while being no more than the condition of a schedule time, just judge the event of unblanking that now triggered, meet two reverse direction acceleration all has the situation that exceeds the threshold value of unblanking to occur simultaneously within a certain period of time, now just controlling mobile terminal unblanks.
In the specific implementation, the twice whipping action that requires user in same direction and in the schedule time of being separated by mobile terminal is sent to opposite direction, thus triggering mobile terminals is unblanked.Be understandable that, twice action of described opposite direction can be on any direction, but for ease of implementing, in the present embodiment, preferred, the either direction that described direction is three-dimensional coordinate, can be also horizontal direction or vertical direction.
Above-mentioned restriction is not that user's whipping causes in order to prevent that mobile terminal from exceeding at some directional accelerations the threshold value of unblanking, and has avoided the event of unblanking causing because of erroneous judgement.
Further, described step S2 also comprises:
When the accekeration of measuring in the some directions of mobile terminal is less than and unblanks threshold value, for whether mobile terminal being triggered to the event of unblanking according to the probable value of the event of unblanking, judge; If mobile terminal is unblanked in one direction, the probable value of event is greater than predetermined threshold with the product of the probable value of the event of unblanking on the reverse direction of this direction in the given time, judges that mobile terminal triggers the event of unblanking;
The probable value of the described event of unblanking does not exceed while unblanking threshold value for measured accekeration when a direction in, the probable value of judging the event of unblanking in described direction be to make progress the party ratio of measured accekeration and the threshold value of unblanking.
In order to overcome more accurately the acceleration figure that shake that user sends when carrying mobile terminal causes, exceed once in a while the threshold value of unblanking, the situation that causes mobile terminal erroneous judgement to be unblanked, whether the calculating that also discloses the probable value of the event of unblanking making progress by the other side in foregoing is the judgement of the event of unblanking.
If the accekeration that mobile terminal is measured in some directions does not reach the threshold value of unblanking, judge the ratio that the probability of the event of unblanking that secondly may send as user is the accekeration recording and the threshold value of unblanking, if within the schedule time, the product of the ratio of the ratio of the accekeration that the reverse direction of this direction records and the threshold value of unblanking and the accekeration upwards calculating the party and the threshold value of unblanking reaches a predetermined threshold value, judges this time as triggering the event of unblanking.
First the probability that determines the event of unblanking that user sends such as: accelerometer in level direction is left 0.98, at ensuing 2 seconds, the probability that is determined at the event of unblanking that in level direction to the right, user sends is 1, the value obtaining two probable values being multiplied each other, be 0.98, and the predetermined threshold of systemic presupposition is 0.95, judge the triggering of this time sending as user event of unblanking.
The probable value computing formula of the above-mentioned event of unblanking is in one direction:
B is the predefined threshold value of unblanking, the accekeration that X is the mobile terminal that upwards determines the party, when the accekeration determining exceeds while unblanking threshold value, at upwards the unblank probability of event of the party, be 1, if do not exceed, judge that at upwards the unblank probability of event of the party be X/B, thereby effectively avoided because user trembles the erroneous judgement of the event of unblanking that may cause, also effectively increased the identification to the event of effectively unblanking, improved the accuracy that dual lock event is judged simultaneously.

H3, when calculating that this side up and unblank the probability of event and be more than or equal to predetermined threshold 0.95, carry out step H4, otherwise judge to be this time a mobile phone shake, the non-event of unblanking;
H4, startup timer, carry out timing;
H5, continue to obtain accekeration in one direction, calculate the probable value of the event of unblanking;
If H6 determines in the unblank probable value of event of the reverse direction of this direction and is more than or equal to 0.95, carry out step H7, if timer does not exceed 2 seconds, proceed to detect, if timer exceeded after 2 seconds, be judged to be the non-event of unblanking;
Multiplying each other of H7, described probable value that step H3 and step H5 are calculated;
If whether the product of two values of H8 exceeds 0.95, carry out step H9, otherwise be judged to be the non-event of unblanking, do not carry out unlock operation;
