First embodiment of the present invention relates to a kind of screen unlock method, is applied to the electronic equipment comprising contact panel.Idiographic flow as shown in Figure 1.
Step 101, receives doubtful unlocking pin information under lock-out state.
Specifically, when electronic equipment is in the lock state (screen is not lighted), by the doubtful unlocking pin information of user's handwriting input on contact panel, described doubtful unlocking pin packets of information is containing character features and writing feature; Character features can be word, word or a sentence, such as, be " literary grace is danced in the air "; Writing feature is for characterizing the individual writing characteristics of importer, and it comprises word size, text point and character calligraph time, namely refers to the size of doubtful unlocking pin, position and writing time.
Wherein, the position that is triggered that word size and text point are sensed by contact panel is calculated.Such as during user's hand-written on contact panel " literary composition " word, point (Dian), horizontal (one), the position that is triggered of skimming (Pie) and right-falling stroke (Fu) are represented by planimetric coordinates.Such as shown in Fig. 2, be the position that is triggered that " literary composition " word is corresponding on the touch pad shown in figure.Wherein, the word size of " literary composition " word can by the height of word and width means, the height of word is the difference of the ordinate of this word peak and minimum point, as the difference of the ordinate of A1 and D3, the width of word is the difference of the horizontal ordinate of this word rightest point and ultra-left point, as the difference of the horizontal ordinate of D3 and D1.The text point of " literary composition " word can be represented by the home-position contact coordinate of each stroke of this word and termination contact coordinate, such as can represent with the coordinate of A1, A2, B1, B3, C1, C3, D1, D3.Certainly, doubtful unlocking pin information is not limited only to word, also can be self-defining symbol.
The character calligraph time comprises whole writing times of doubtful unlocking pin, preferably, also comprises each stroke writing time of doubtful unlocking pin.
Step 102, judges whether character features mates.If so, then step 103 is entered; If not, step 101 is returned.
Wherein, preset unlocking pin information and also comprise character features and writing feature.Presetting unlocking pin information is that user arranges interface at password and repeatedly inputs unlocking pin, and electronic equipment receives multiple unlocking pin sample informations of user's input, produces preset unlocking pin information according to multiple unlocking pin sample information.
Specifically, the character features of doubtful unlocking pin received and the character features of default unlocking pin carry out contrasting to judge whether the two matches by electronic equipment.Such as, the character features presetting unlocking pin is " literary composition ", then, only have when the character features of the doubtful unlocking pin received is also for " literary composition ", just can judge the two coupling.
Preferably, default unlocking pin can comprise multiple unblock word, and character features comprises the character feature of each unblock word and the sequencing feature of each unblock word.Character feature is the word that comprises of character features or symbol, and sequencing feature refers to the sequencing of word that character features comprises or symbol.The character features such as presetting unlocking pin is " literary grace is danced in the air ", then, only have when the character features of the doubtful unlocking pin received is also for " literary grace is danced in the air ", the two coupling can be judged, if the character features of the doubtful unlocking pin received is " literary composition dances in the air and adopts ", although character feature mates, because sequencing feature does not mate, so do not mate both judging.
In step 103, judge whether writing feature mates.
Writing feature comprises word size, text point and character calligraph time.Whether respectively electronic equipment judges word size, text point, the character calligraph time Corresponding matching of the word size of doubtful unlocking pin, text point, character calligraph time and default unlocking pin.Present embodiment does not do any restriction to the item that writing feature comprises, can select in practical application word size, one of them or any two of text point and character calligraph time combination as necessary writing feature.
Writing feature due to default unlocking pin information produces according to the writing feature of multiple unlocking pin sample information, such as, average, so each writing feature that default unlocking pin packets of information contains can have an error range respectively.The coupling of word size refers to the error amount of the word size of word size by calculating doubtful unlocking pin information and default unlocking pin information, and whether error in judgement value just can judge in error range whether the word size of the two mates.Such as: as shown in Figure 3, the difference of the peak E1 of unlocking pin " literary composition " and the ordinate of minimum point H3 is preset: Y
e1-Y
h3=16.2-2.8=13.4; The difference of the horizontal ordinate of rightest point H3 and ultra-left point F1: X
h3-X
f1=15.6-3.0=12.6.As shown in Figure 2, the difference of the peak A1 of doubtful unlocking pin " literary composition " and the ordinate of minimum point D3: Y
a1-Y
d3=17.5-3.1=14.4, the difference X of the horizontal ordinate of rightest point D3 and ultra-left point B1
d3-X
b1=16.1-1.9=14.2, vertical direction error upwards: 14.4-13.4=1.0; Error in horizontal direction: 14.2-12.6=1.6.The error range of the word size that electronic equipment internal is preset is such as 0 ~ 3, and 1.0 and 1.6 all within 0 ~ 3, and electronic equipment judges that the word size of this doubtful unlocking pin information is mated with the word size of default unlocking pin information.
The coupling of text point refers to the home-position contact coordinate of the home-position contact coordinate of each stroke by calculating doubtful unlocking pin information respectively and each stroke of termination contact coordinate and default unlocking pin information and stops the error amount of contact coordinate, whether error in judgement value is in the error range allowed, if in error range, electronic equipment can judge that the two matches, if not in error range, then the text point of the two does not match.As shown in Figure 3, for point (Dian) stroke of default unlocking pin, the home-position contact E1 coordinate of point (Dian) stroke is (7.3,16.2), the home-position contact A1 coordinate of point (Dian) stroke of doubtful unlocking pin is (7.4,17.5), X
a1-X
e1=7.4-7.3=0.1, Y
a1-Y
e1=17.5-16.2=1.3, the error range of the text point that electronic equipment internal is preset is such as 0 ~ 2,0.1 and 1.3 all in the error range of 0 ~ 2; Preset the termination contact E2 (9.2 of point (Dian) stroke of unlocking pin, 14.1), the termination contact A 2 (8.9 of point (Dian) stroke of doubtful unlocking pin, 15.3), XE2-XA2=9.2-8.9=0.3, YA2-YE2=15.3-14.1=1.2,0.3 and 1.2 all in the error range of 0 ~ 2; Therefore point (Dian) stroke presetting unlocking pin meets the requirements, similar, as horizontal stroke (one) stroke of default unlocking pin, slash (Pie) stroke, right-falling stroke (Fu) stroke is when all meeting the requirements, and electronic equipment judges that the text point of doubtful unlocking pin word and the text point of default unlocking pin word match.Contrary, if preset point (Dian) stroke of unlocking pin, horizontal stroke (one) stroke, slash (Pie) stroke, right-falling stroke (Fu) one of them of stroke be undesirable, then and electronic equipment judges that the text point of doubtful unlocking pin word does not mate with the text point of default unlocking pin word.
The character calligraph time comprises the writing time of whole writing time of this word and each stroke of this word.So electronic equipment is write initial time according to what record and writes whole writing times that the end time just can calculate this word.Electronic equipment is by calculating the whole writing time of word of doubtful unlocking pin information and the error amount of whole character calligraph times of default unlocking pin information, and whether whether error in judgement value just can judge in error range that the word of doubtful unlocking pin information is all write mates with the whole writing time of word of default unlocking pin information.Such as: during the doubtful unlocking pin word of user writing, touch screen, the time this moment that contact panel is recorded (such as, be exactly 16:25:32:057) write initial time, the time of the user recorded last touch screen in writing process (such as, be exactly 16:25:36:568) write the end time, so whole writing times of this doubtful unlocking pin word are exactly 16:25:36:568-16:25:32:057=00:00:04:511=4.511 second.If the writing time of preset password word is 4.300 seconds, the error amount of the writing time of so doubtful unlocking pin word and default unlocking pin word is exactly 0.211 second, the error range of the character calligraph time that electronic equipment internal is preset is 0 ~ 1, because 0.211 second in the scope of 0 ~ 1, electronic equipment judges the character calligraph time of doubtful unlocking pin word and the character calligraph time match of default unlocking pin.
The writing time coupling of each stroke of word refers to according to home-position contact time of each stroke and stops the writing time that contact time point calculates this stroke, the writing time of the same unicursal of itself and default unlocking pin information is contrasted, the error amount of both calculating, whether decision errors value is in error range, if in error range, just can judge that the writing time of this stroke matches.For point (Dian) stroke of " literary composition " word of doubtful unlocking pin, the origin coordinates A1 of point (Dian) stroke and the touch time point of termination coordinate A2 are 16:25:32:057 and 16:25:33:034 respectively, 0.977 second used time; The writing time presetting point (Dian) stroke of unlocking pin " literary composition " word is 0.870 second, and the error range of each stroke that electronic equipment internal is preset is 0 ~ 0.5 second.The error of point (Dian) stroke is: 0.977-0.870=0.107 second, and 0.107 second in the error range of 0 ~ 0.5 second; Therefore the writing time presetting point (Dian) stroke of unlocking pin meets the requirements, similar, as horizontal stroke (one) stroke of default unlocking pin, slash (Pie) stroke, right-falling stroke (Fu) writing time of stroke is when all meeting the requirements, electronic equipment judges that the writing time of each stroke writing time of doubtful unlocking pin word and each stroke of default unlocking pin word matches, thus judges that doubtful unlocking pin character calligraph time and default unlocking pin character calligraph time match; Contrary, if preset point (Dian) stroke of unlocking pin, horizontal stroke (one) stroke, slash (Pie) stroke, right-falling stroke (Fu) one of them of stroke writing time be undesirable, then electronic equipment judges that each stroke writing time of doubtful unlocking pin word does not mate with each stroke writing time of default unlocking pin word, thus judges that the doubtful unlocking pin character calligraph time did not mate with the default unlocking pin character calligraph time.
The word size of the word size of above-mentioned doubtful unlocking pin word, text point and character calligraph time and default unlocking pin word, text point and character calligraph time all mate, so processor will judge doubtful unlocking pin word and default unlocking pin characters matching, enters step 104
Step 104, enters released state.Electronic equipment, after judging doubtful unlocking pin word and default unlocking pin characters matching, can be lighted screen and enter duty.
