A kind of touch screen unlocking method based on mobile terminal described in first embodiment of the invention, as shown in figure 1, bag
Include：
Step S100, mobile terminal set the touch point of N number of order for having priority, phase in touch-screen unlock interface in advance
The time range Ti of slip between adjacent touch point is simultaneously stored, wherein, described N, i are the natural number more than 1, and i≤N.
When it is implemented, setting two or more touches for having a sequencing in mobile terminal touch screen unlock interface
Point, P1、P2、P3、……、PNTo there is the touch point on touch-screen, and its order is P1、P2、P3、……、PN, the present invention and 4
Illustrated exemplified by touch point, as shown in Fig. 2 schematic diagram when being illustrated in figure 2 N=4, certain P1、P2、P3、P4Four touches
The position of point can be any.
When user unlocks, it is necessary to make to slide touch successively by the sequencing of these touch points, user must be according to P1、P2、
P3、……、PNOrder, successively by P1Slide into P2, by P2Slide into P3... ..., by PN-1Slide into PN；It is illustrated in figure 3
Sliding trace between the tactile lock path schematic diagram of touch point position shown in Fig. 2, two of which touch point can be it is arbitrary, such as
By P shown in Fig. 21Slide into P2Sliding trace be a curve, and P2Slide into P3, P3Slide into P4Track be straight line.
In unblock, certain requirement must is fulfilled for from the used time of a touch point to next touch point；Tool
Body is to slide into P by arbitrfary point1Time be T1, by P1Slide into P2Time be T2, by P2Slide into P3Time be T3, by
P3Slide into P4Time be T4... ..., by PN-1Slide into PNTime be TN；Wherein, T1、T2、T3、……、TN-1、TNIt is
One time range；Shown in Fig. 4, T2 need to be met from the P1 times for sliding into P2 in releasing process, from P2 slide into P3 when
Between need to meet T3, need to meet T4 from the P3 times for sliding into P4.
Step S200, the unlock instruction for detecting user, obtain user and touch the touch point coordinates of touch-screen and touch phase
The time difference of adjacent touch point, judge whether between meeting the touch point coordinates order pre-set and touching adjacent touch point
The time range of slip；Success is unlocked if above-mentioned condition is met, otherwise prompting unblock failure.
