The embodiment of the present invention is mainly to utilize mobile terminal as the acceleration transducer in smart mobile phone or gyro sensor, and the data that gather by sensor calculate the displacement of mobile terminal, namely the track of motion of mobile terminals.Judge that by this track whether the release pattern that user inputs is correct, if correctly just untie screen lock, on the contrary failure.
First, mobile terminal is entered and treats released state:
Because the mobile terminals such as smart mobile phone tend to close the sensor such as gyroscope or acceleration when screen is closed, thereby save power supply, so the first step must first be opened screen, make gyroscope or acceleration transducer working properly.
The second, determine starting point:
Receive and identify the single-point touches of the optional position S0 of user to touch-screen, S0 is the starting point of release input, and the position of the mobile terminal starting from S0 is moved as release and inputted.
Because it is all release input that user does not often wish to open all shift actions after screen, some irrelevant inputs of so easy introducing, cause release failure.
Therefore, the embodiment of the present invention confirms that starting point can make user pin any one position S0 of touch-screen with hand, and any track of mobile terminal after this starting moves the input of all thinking release, until user's hand leaves touch-screen.
The 3rd, input release pattern:
User holds intelligent terminal at the contactless release pattern that marks.
The input of release pattern need to be followed certain rule: contactless pattern release, and similar with the touchscreen pattern release of current Android platform, be all the pattern of input to be translated into password compare.Because two kinds of unlock method input modes are completely different, in order to improve the discrimination of contactless pattern release, introduce the rule of some inputs here.
1. track number
As shown in Figure 1, nine points being above numbered is 1 ~ 9.9 points of Here it is composition release pattern.
2. acquiescence starting point is certain point wherein, to put 5 as S0 as example
With touch-screen contact pattern release difference, aerial release need to have suitable acquiescence starting point, because aerial track does not have big or small concept, can only judge from trajectory direction and relative position.If it is improper to select without acquiescence starting point or starting point, the aerial track of Fig. 2 so, just can corresponding multiple release pattern generating ambiguity, as Fig. 3, and Fig. 4 and Fig. 5.In order to facilitate the identification of gyroscope track, selected center's point (point 5) is starting point.
3. track is to the conversion of password.According to the point of the specific coding of track process, coding is lined up in order, if the keying sequence of Fig. 6 is 56357.
4. Password Length.Track is at least through 4 points, at most through 9 points; Namely the length of password is 4 ~ 9.
5. the direction of track can only have 8:
degree,
degree,
degree,
degree and
degree.
As shown in Figure 7,8 kinds of tracks that dotted line represents are illegal, there is no object of reference because draw when aerial track, and the error at the inclination angle of track can be larger, are difficult in this case distinguish various inclination angles.In Fig. 8, be all legal tracks.
The 4th, confirm end point:
When user's hand leaves touch-screen, represent pattern end of input.
The 5th, mobile terminal is identified track, Output rusults:
Mobile terminal is stored and is identified the track of input, converts corresponding password to, compares with the password of setting, if coupling screen lock is untied, if do not mated, screen display input error, waits for input next time.Input unsuccessfully, will lock for 30 seconds for continuous 5 times.
