Refer to rotation after and rotation before respectively with respect to the deflection angle of a predetermined datum line；Wherein, the definition of the predetermined datum line is：With
The interface central point of the mobile terminal is reference axis central point, with the lateral symmetry of the self-capacitance touch screen of the mobile terminal
Center line, longitudinally asymmetric center line are respectively that x coordinate axle, y-coordinate axle set up coordinate system, using the x coordinate axle to be described predetermined
Datum line.Detection obtain coordinate process equivalent to, it is assumed that there is a virtual suspension screen parallel with mobile phone interface the position of human hand,
The position O1 points of human hand rotation, by the O1 points along the x-axis direction first（Forward or backwards）, move in y-axis, then by the y
O1 points on axle are along the y-axis direction（Forward or backwards）, move to mobile phone interface central point O position, i.e., described central point O with

Calculate obtain after user's finger rotation and before rotation relatively described predetermined datum line respectively deflection angle；When it is implemented, can be with
Coordinated according to the tan and SIN function before rotation with angle after rotation and calculated, such as the angle before rotating is ɑ, is revolved
Angle after turning is β, and the coordinate value before rotation is（x1、y1）, postrotational coordinate value is（x2、y2）, carried out using tan
Calculate, then tan ɑ=y1/ x1, tan β=y2/x2, then ɑ=arctan (y1/ x1), and β=arctan (y2/ x2)；When running into rotation
Before turning or when postrotational angle is close to 90 °, now, then calculated using SIN function, if L1=（y1 2+x1 2）1/2, L2=（y2 2
+x2 2）1/2, then ɑ=arcsin (y1/ L1), and β=arcsin (y2/L2)。

The variation tendency of degree then judges the direction of rotation of user's finger as rotate counterclockwise gradually to increase；And when user's finger rotation
When being afterwards negative value with the difference of the deflection angle before rotation, the variation tendency of deflection angle judges to use to be gradually reduced, then
The direction of rotation of family finger is to turn clockwise.For example, when the preceding deflection angle of rotation is 30 °, rotation retrodeviates gyration for 45 °,
The difference of deflection angle is 15 °, and it is on the occasion of the variation tendency of deflection angle then judges the rotation of user's finger gradually to increase
Turn direction for rotate counterclockwise；In another example, when deflection angle is 60 ° before rotation, it is 45 °, deflection angle that rotation, which retrodeviates gyration,
Difference be -15 °, it is negative value, the variation tendency of deflection angle to be gradually reduced, then judge the direction of rotation of user's finger as
Turn clockwise.
Step S230, the direction of rotation according to user's finger, control mobile terminal interface according to the anglec of rotation with
The rotation of user's finger and rotate.When it is implemented, when the finger of user turns clockwise or during rotate counterclockwise, controlling mobile phone
