Body, the method that the present embodiment provides can include：
Step 101, when pressure screen is in screen lock state, the pressure screen display it is at least one treat by
Power region.
Before this step, terminal device reads the flag data of current screen lock state first, according to described
Flag data judge whether the pressure screen is currently in the screen lock state, are locked judging that pressure screen is in
During screen state, this step is performed.
Step 102, the pressure information for obtaining user's pressing that the pressure screen receives.
Specifically, the pressure information includes：Coordinate information (x, y), size information p, directional information a

In rapid, first coordinate data and second coordinate data progress and computing of storage obtain again
Result of calculation, stored, and at least one visualization force area is mapped as on the pressure screen
Domain.
For simplified operation, the visualization stress area obtained after single Force Calculation will be mapped as one piece of circle
Or one piece of elliptical region；It can be obtained according to mathematical knowledge：On a plane coordinates, one piece of elliptical region
It can be determined by the coordinate of 3 points：Origin O, major semiaxis terminal A, semi-minor axis terminal B.Special,
When the distance a of oval major semiaxis terminal A to origin, and the distance b of semi-minor axis terminal B to origin are equal
When, this ellipse is circle.
Specifically, assume known to three points O, A, B coordinate be respectively O (X, Y), A (X, Y),
B (X, Y), wherein, point O is oval origin, and point A is oval major semiaxis end points, and point B is ellipse
Round semi-minor axis end points, point O, A, B coordinate are it is also possible that represent：
XO, YOPoint O X-axis coordinate, Y-axis coordinate is represented respectively；
XA, YAPoint A X-axis coordinate, Y-axis coordinate is represented respectively；
XB, YBPoint B X-axis coordinate, Y-axis coordinate is represented respectively；
Then meet lower surface function x a little, y-coordinate all on an ellipse：
[(x-XO)cosθ+(y-YO)sinθ]2/a2+[(y-YO)cosθ-(x-XO)sinθ]2/b2=0
In function：
XO、YOFor point O X-axis coordinate, Y-axis coordinate, be it is known,
θ is long axis direction vector and angle, tan θ=(Y formed by X-axisA-YO)/(XA-XO), you can by
Known point coordinates is derived；

Go out；
B is oval semi-minor axis length, b=√ (XB-XO)2+(YB-YO)2, you can derived by known point coordinates
Go out；
It is special, if a=b, meet this function x a little, y-coordinate all on a circle
To sum up：If it is known that three points O, A, B coordinate, the ellipse of an optional position can be determined
Shape or a circle.Fig. 2 is referred to, Fig. 2 is to be determined in plane by the coordinate of tri- points of O, A, B

The coordinate O (X, Y), A (X, Y), B (X, Y) of tri- points of B：
F1 (x, y, p, a, t)=>O (X, Y)
F2 (x, y, p, a, t)=>A (X, Y)
F3 (x, y, p, a, t)=>B (X, Y).
The coordinate of this 3 points will determine one piece of circle or elliptical region, i.e., by information x, y, the p of power,
One group of data O (X, Y) that a, t are generated after calculating, A (X, Y), B (X, Y) are mapped as
One visualization stress area shows that this region can be referred to as Area1 on screen, judges that this region is
It is no to meet unlocking condition.
If it is determined that unlocking condition wouldn't be met, then continue to detect pressure.After pressure second of stress of screen,
A region Area2 is still calculated as stated above, now needs the Area1 of first time and second
Area2 carry out region merging technique, then judges whether the new region Area ' after merging meets unlocking condition again,
The process of this region merging technique is to employ " logical AND " calculating, i.e. Area1＆＆Area2=Area '.Ginseng
It is the schematic diagram of region merging technique to see Fig. 3, Fig. 3.
Step 104, judging that described at least one treat is completely covered at least one visualization stress area
During stress area, the pressure screen is unlocked.
Further, after the pressure screen is unlocked, the result of calculation of storage is removed, and by the mark
Know position data and be set to non-screen lock state.
