Below in conjunction with specific embodiment, the realization of the present invention is described in detail:
What Fig. 1 illustrated the control method of the screen display direction that the embodiment of the present invention provides realizes flow process, and details are as follows:
In S101, obtain finger by fingerprint sensor and perform the glide direction of slide on mobile terminals.
Described mobile terminal, refers to the computer equipment that can use in movement, and it is equipped with intelligent operating system, includes but not limited to smart mobile phone, intelligent watch, notebook, panel computer, POS even vehicle-mounted computer.Specifically, the embodiment that S101 can pass through as shown in Figure 2 realizes:
In S201, gather, by described fingerprint sensor, the fingerprint image that described slide produces.
In embodiments of the present invention, mobile terminal is integrated with fingerprint module, is built-in with fingerprint recognition chip in this fingerprint module, fingerprint recognition chip detection to finger on fingerprint module, produce touch operation time, fingerprint image is acquired, and the frequency of collection is determined by the rate of scanning of fingerprint recognition chip.The harvester of fingerprint image may be located at the mobile terminal back side, the screen module of mobile terminal can also be positioned at, therefore, when finger enterprising line slip operation at the back side of mobile terminal or screen, fingerprint image produced in slide process is acquired, gets one group of continuous print fingerprint image.
In S201, the described fingerprint image collected is processed, obtains the glide direction of described slide.
In embodiments of the present invention, it is possible to the track that the fingerprint image produced in slide process according to finger is formed, the glide direction of this slide is determined.
S202 implements as shown in Figure 3:
In S301, calculate fingerprint image centre coordinate on the screen described in fingerprint image and second described in collect first.
Wherein, first fingerprint image and the second fingerprint image are two width in the S102 one group of continuous print fingerprint image collected, it can be the two width fingerprint images therefrom selected according to preset rules, such as, the first fingerprint image and the second fingerprint image need the certain times of collection of the certain acquisition time in interval or interval.In order to more precisely judge the glide direction of slide, it is preferable that the first fingerprint image can the first width fingerprint image for collecting in slide, and the second fingerprint image can be last width fingerprint image collected in this slide.
After the collection completing fingerprint image, it is possible to get the position of the left and right edges of every fingerprint image.At this, exemplarily, it is possible to the lower left corner of mobile terminal screen for zero, screen lower limb is X-axis, and screen left hand edge is Y-axis, it is established that two dimensional surface coordinate system, then positioned by screen, gets the left hand edge X of every fingerprint imagemin, right hand edge Xmax, top edge YminAnd lower limb Ymax, and the centre coordinate (X of fingerprint image is calculated according to below equationp, Yp):
Xp=(Xmax-Xmin)/2, Yp=(Ymax-Ymin)/2。
Making the first fingerprint image is the first width fingerprint image collected in slide, and the second fingerprint image is last width fingerprint image collected in slide, then to the first fingerprint image centre coordinate (Xp1, Yp1) acquisition formula as follows:
Xp1=(Xmax_1-Xmin_1)/2, Yp1=(Ymax_1-Ymin_1)/2,
Wherein, Xmax_1It is the right hand edge of the first fingerprint image, Xmin_1It is the left hand edge of the first fingerprint image, Ymax_1It is the lower limb of the first fingerprint image, Ymin_1It it is the top edge of the first fingerprint image.
To the second fingerprint image centre coordinate (Xp2, Yp2) acquisition formula as follows:
Xp2=(Xmax_2-Xmin_2)/2, Yp2=(Ymax_2-Ymin_2)/2,
Wherein, Xmax_2It is the right hand edge of the second fingerprint image, Xmin_2It is the left hand edge of the second fingerprint image, Ymax_2It is the lower limb of the second fingerprint image, Ymin_2It it is the top edge of the second fingerprint image.
In S302, obtain the acquisition time of fingerprint image described in fingerprint image and second described in first poor.
In S303, described centre coordinate and described acquisition time according to calculating are poor, calculate the sliding speed of described slide.
The acquisition time of the first fingerprint image and the second fingerprint image is poor, refer to the difference between both the time gathering the first fingerprint image and the time gathering the second fingerprint image, concrete, the acquisition time t2, then acquisition time difference t=t2-t1 during acquisition time t1 and second fingerprint image of the first fingerprint image can be recorded.
The sliding speed of slide can be calculated according to below equation:
Xv=(Xp2-Xp1)/t, Yv=(Yp2-Yp1)/t,
Wherein, XvFor slide sliding speed in the X-axis direction, YvFor slide sliding speed in the Y-axis direction, (Xp1, Yp1) it is the centre coordinate of the first fingerprint image, (Xp2, Yp2) it is the centre coordinate of the second fingerprint image, the acquisition time that t is the first fingerprint image and the second fingerprint image is poor.
In S304, the magnitude relationship according to described sliding speed with the sliding speed threshold value preset, obtain the glide direction of described slide.
Make XfFor the sliding speed threshold value in default X-direction, YfFor the sliding speed threshold value in default Y direction, then can according to XvWith XfMagnitude relationship, and according to YvWith YfMagnitude relationship, determine the glide direction of slide.Specifically:
If Xv<-XfAnd-Yf<Yv<Yf, it is determined that the glide direction of described slide is the first glide direction；
If Xv>XfAnd-Yf<Yv<Yf, it is determined that the glide direction of described slide is the second glide direction；
If-Xf<Xv<XfAnd Yv<-Yf, it is determined that the glide direction of described slide is the 3rd glide direction；
If-Xf<Xv<XfAnd Yv>Yf, it is determined that the glide direction of described slide is the 4th glide direction.
In the embodiment shown in fig. 3, the acquisition process of glide direction is only needed to calculate the centre coordinate of the wherein two width fingerprint images collected, and the acquisition time difference in conjunction with this two width fingerprint image determines glide direction, its amount of calculation only N level, method is simple, consuming time few, and operation live effect is good.
In S102, according to adjusting the display interface of mobile terminal described in parameter adjustment, described adjustment parameter includes described glide direction.
Specifically, the embodiment that S102 can pass through as shown in Figure 4 realizes:
In S401, based on default corresponding relation, it is determined that corresponding to direction of rotation and the anglec of rotation of described adjustment parameter.
In S402, rotate the display interface of described mobile terminal according to described direction of rotation and the described anglec of rotation.
In embodiments of the present invention, preset corresponding relation, in this corresponding relation, the corresponding direction of rotation of different adjustment parameter and the anglec of rotation.Described adjustment parameter, at least includes the glide direction got in S102, further, adjust parameter and can also include the laying state of mobile terminal, now, laying state and glide direction form one group and adjust parameter, and this group adjusts parameter uniquely a corresponding direction of rotation and the anglec of rotation.
Laying state for mobile terminal, in embodiments of the present invention, utilize the built-in gravity sensor (GV-sensor) of mobile terminal or acceleration transducer (G-sensor), in real time mobile terminal acceleration on each axial direction can be detected, and determine the laying state of mobile terminal according to testing result.
Such as, as shown in Figure 5, with the mobile terminal screen lower left corner for zero, (position of zero is not construed as limiting by the embodiment of the present invention, can also using other positions of mobile terminal as zero) set up three-dimensional system of coordinate, the acceleration of gravity of X-axis, Y-axis and Z axis in x, y, z respectively this coordinate system, then utilize the sensing device in mobile terminal, it is possible to detect the numerical value of x, y, z, judge, with this, the laying state that mobile terminal is current.Herein, only it is set forth under the three-dimensional system of coordinate shown in Fig. 5, several typical judgement situations:
1, work as x=y=0, z > 0 time, detect that mobile terminal is in screen horizontal positioned state upwards；
2, work as x=z=0, y > 0 time, detect that mobile terminal is in laying state straight up；
3, work as x=z=0, y and < when 0, detect that mobile terminal is in laying state straight down；
4, work as y=z=0, x > 0 time, detect that mobile terminal is in the screen laying state towards left side；
5, work as y=z=0, x and < when 0, detect that mobile terminal is in screen towards laying state to the right.

Namely, in the present embodiment, arranging of default corresponding relation can be adjusted according to the actual demand of user, include glide direction and laying state adjusting parameter, when mobile terminal is in different laying states, interface direction of rotation corresponding to fingerprint glide direction and the anglec of rotation can self-definings, and it is stored among the data base of mobile terminal by arranging result, so, the execution process of S401 just can transfer out this corresponding relation preset from data base, and according to the laying state of mobile terminal, and the glide direction of fingerprint slide, determine the direction of rotation simultaneously corresponding with above-mentioned two parameter and the anglec of rotation, the display interface of mobile terminal is rotated according to this direction of rotation and the anglec of rotation.
Such as, when adjusting parameter and only including glide direction, as shown in Figure 6, mobile phone carrying out the setting of corresponding relation in advance, direction of rotation and the anglec of rotation that different glide directions is corresponding are as follows:
Direction 1 is for slide to the left, and corresponding display interface direction of rotation and the anglec of rotation be: 90-degree rotation counterclockwise；
Direction 2 is for slide to the right, and corresponding display interface direction of rotation and the anglec of rotation be: dextrorotation turn 90 degrees；
Direction 3 is slide downward, and corresponding display interface direction of rotation and the anglec of rotation be: suitable/to revolve turnback counterclockwise；
Direction 4 is upward sliding.Corresponding display interface direction of rotation and the anglec of rotation be: suitable/to revolve turnback counterclockwise.
So, when detect finger perform on mobile phone the glide direction of slide be slide downward time, according to default corresponding relation, it is determined that direction of rotation and the anglec of rotation that this glide direction is corresponding are dextrorotation turnback, then by the display interface of mobile phone from current state dextrorotation turnback.
Again such as, when adjusting parameter and including glide direction and laying state, as it is shown in fig. 7, for the laying state that mobile phone is left side transverse direction, mobile phone carries out the setting of corresponding relation in advance, direction of rotation and the anglec of rotation that different glide directions is corresponding are as follows:
Direction 1 is slide downward, and corresponding display interface direction of rotation and the anglec of rotation be: suitable/to revolve turnback counterclockwise；
Direction 2 is upward sliding.Corresponding display interface direction of rotation and the anglec of rotation be: suitable/to revolve turnback counterclockwise；
Direction 3 is for slide to the right, and corresponding display interface direction of rotation and the anglec of rotation be: dextrorotation turn 90 degrees；
Direction 4 is for slide to the left, and corresponding display interface direction of rotation and the anglec of rotation be: 90-degree rotation counterclockwise.
So, when mobile phone is in the laterally disposed state in left side, when detecting that finger performs the glide direction of slide for sliding to the left on mobile phone, according to default corresponding relation, determine that direction of rotation corresponding to this glide direction and the anglec of rotation are 90-degree rotation counterclockwise, then by the display interface of mobile phone from current state 90-degree rotation counterclockwise.
