In order better to understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
Embodiment mono-
The embodiment of the present application one provides a kind of method of information processing, is applied in the electronic equipment with touch-display unit, and described electronic equipment can be mobile phone, notebook computer, which kind of electronic equipment panel computer etc., be for described electronic equipment, and the application is not restricted.
As shown in Figure 1, the method for described information processing comprises the steps:
S101: detect and whether have the first touch control operation in described touch-display unit.
In specific implementation process, the form of the first touch control operation that electronic equipment can detect has multiple, for example, can be line touch control operation always, can be also a curve touch control operation.
Detect in described touch-display unit, whether there is the first touch control operation based on step S101, in the time the first touch control operation being detected, execution step S102, that is: in the time having described the first touch control operation, respond described the first touch control operation, M the touch point positional information that obtains M touch point, M is more than or equal to 3 integer;
In specific implementation process, step S102 specific implementation method has multiple, and the embodiment of the present application provides two kinds of preferred methods.
The method of the preferred implementation step S102 of the first, specifically comprises: scan one by one described touch-display unit based on a predeterminated frequency, obtain successively M touch point positional information of a described M touch point.
Concrete, be which kind of electronic equipment according to electronic equipment, and the size of the touch-display unit of electronic equipment is determined the frequency of scanning.
The method of the preferred implementation step S102 of the second as shown in Figure 2, specifically comprises the steps:
S1021: respond described the first touch control operation, scan one by one described touch-display unit, obtain first touch point positional information.
In specific implementation process, be specifically as follows and detect that the first touch control operation is in the time that touch-display unit has first touch point as step S102, respond the first touch control operation, touch-display unit is carried out to full screen scanning, concrete principle is: touch-display unit forms capacitance matrix with X-axis, Y-axis cross-distribution, in the time of finger touches screen, can pass through the scanning one by one of X, Y-axis, the capacitance variations of touch position detected, thereby calculate the positional information at first touch point place.
First touch point positional information obtaining based on step S1021, execution step S1022, that is: getting successively j is 1 to M-1 integer, based on described j touch point positional information, determine j preset range, wherein, the area of described j preset range is less than the area of described touch-display unit;
J the preset range of determining based on step S1022, execution step S1023, that is: in described j preset range, detect and whether have j+1 the touch point corresponding with described the first touch control operation;
In specific implementation process, step S1023 specifically comprises:
First, in Y direction, K point in described j preset range applied to a driving voltage;
Then, detect described K the X-direction of putting and whether have an induced voltage;
Again then, in the time detecting that the X-direction of n point in described K point has described induced voltage, determine that described n point is described j+1 touch point.
Then, execution step S1024: in the time there is described j+1 touch point, obtain j+1 touch point positional information, in the time that j+1 equals M, obtain described M touch point positional information.
In specific implementation process, the implementation step that circulates successively S1022 ~ S1023, specific implementation method is:
First,, based on first touch point positional information, default first preset range detects second touch point within the scope of first, in the time there is second touch point, obtains second touch point positional information.Then,, based on second touch point, default second preset range detects the 3rd touch point in second preset range, in the time there is the 3rd touch point, obtains the 3rd touch point positional information.Repeat this process, until obtain M touch point positional information.
Concrete, j preset range can adopt two kinds of methods to set:
The first, point centered by j touch point positional information, the capacitance matrix point being intersected to form by N article of X-axis and N article of Y-axis forms j preset range, and N value can be set flexibly, and the scope of capacitance matrix point is within the scope of touch-display unit.
The second, centered by j touch point positional information, L be radius set a round scope in capacitance matrix point be j preset range, L value can be set flexibly, the scope of capacitance matrix point is within the scope of touch-display unit.
The embodiment of the present application is described the method for the touch point positional information of determining j touch point as an example of first method example, for example: preset range N equals 5, the positional information of first touch point is C (x, y), and the capacitance matrix point of preset range is as following table:
| C(x-2,y-2) | C(x-2,y-1) | C(x-2,y) | C(x-2,y+1) | C(x-2,y+2) |
| C(x-1,y-2) | C(x-1,y-1) | C(x-1,y) | C(x-1,y+1) | C(x-1,y+2) |
| C(x,y-2) | C(x,y-1) | C(x,y) | C(x,y+1) | C(x,y+2) |
| C(x+1,y-2) | C(x+1,y-1) | C(x+1,y) | C(x+1,y+1) | C(x+1,y+2) |
| C(x+2,y-2) | C(x+2,y-1) | C(x+2,y) | C(x+2,y+1) | C(x+2,y+2) |
First, in N equals 5 scope, the Y direction of each point in upper table is applied to a driving voltage, the value of driving voltage is any magnitude of voltage between 3V ~ 5V.For example: the driving voltage applying is 4V, then, read inductive voltage value in X-direction, in the time that the inductive voltage value reading is identical with driving voltage, judge that this point is not touch point, in the time that the inductive voltage value reading is less than added driving voltage 4V, determine that this point is second touch point, for example: except a C (x-1, y+1) X-direction inductive voltage value is less than outside 4V, all the other each points in default scope are 4V at the inductive voltage value of X-direction, so can determine that C (x-1, y+1) is second touch point.Determine C (x-1, y+1) be after second touch point, the coordinate declining via calculating voltage, judge the positional information of touch point, concrete principle is: the ITO(N-type oxide semiconductor conducting electricity on the screen due to touch control display) glass provides under voltage and forms uniform electric field at four jiaos, and because human body is charged conductor, therefore, in the time that touching contact panel hard glass surface, human body can cause coupling capacitance, thereby the part electric current that siphons away below ito glass causes voltage drop, a predetermined true origin, determine the positional information of the second touch point based on true origin.
M touch point positional information of M the touch point obtaining based on step S102, execution step S103 based on described M touch point positional information, determines first track corresponding with the motion track of described the first touch control operation that is:.
In specific implementation process, obtain after whole touch point positional informations of the first track corresponding with the motion track of the first touch control operation, just obtain the coordinate information of whole touch points, if, after step S101 ~ S102, obtain the coordinate information of 5 touch points, be respectively: C (20,20), C (21,20), C (21,21), C (22,22), C (23,23).Can be based on C (20,20), C (21,20), C (21,21), C (22,22), these 5 coordinate points of C (23,23) are determined the first track.
The first track of determining based on step S103, execution step S104, that is: getting successively i is 1 to M, it is one pre-conditioned whether i the touch point positional information that judges i touch point meets;
In specific implementation process, step S104 specifically comprises the steps:
Judge whether the minor increment between described i touch point and described the first track is less than a predetermined value; And/or whether the voltage drop value that judges described i touch point meets a predetermined voltage drop-out value.
Concrete, can adopt multiplely pre-conditioned M touch point positional information in the first track of determining in step S103 to be judged one by one, the application provide two kinds preferred pre-conditioned:
The first: predetermined condition can be that the minor increment between i touch point and described the first track is less than or equal to Xmm, judge successively the 1st of the first track, 2,3 ... ..M whether the minor increment of a touch point and the first track is less than or equal to Xmm, wherein, X value can be set voluntarily, and the application does not limit, to meet the demand of distinct electronic apparatuses.
The second: pre-conditioned can be that the voltage drop value of i touch point is more than or equal to YV, judge successively the first track M touch point the 1st, 2,3 ... ..M whether the voltage drop value of a touch point is more than or equal to YV, touch-display unit and electronic equipment difference, pre-conditioned voltage drop value difference to some extent, so the application does not limit.
In specific implementation process, can be according to judging whether i touch point meets that one or both in pre-conditioned of the first, the second are pre-conditioned determines that i touch point is offset point.
For example, the first track that step S103 determines comprises: C (20,20), C (21,20), C (21,21), C (22,22), five touch points of C (23,23), according to the pre-conditioned C(21 that judges of the first, 20) distance of distance the first track is 2mm, simultaneously C(21,20) voltage drop value is 0.05V,, if electronic equipment is pre-conditioned be: minor increment is less than or equal to 1mm, voltage drop value: be more than or equal to 0.1V, can judge C(21,20) this touch point belongs to offset point.
I the touch point positional information of judging at step S104 is not inconsistent unification when pre-conditioned, and that is: execution step S105 not meeting describedly when pre-conditioned, determines that described i touch point is the offset point of relatively described the first track.
In specific implementation process, after execution step S104, the method for described information processing also comprises: meeting describedly when pre-conditioned, determine that described i touch point is the point on described the first track.
In specific implementation process, after step S105, in order to realize the technique effect of the first level and smooth corresponding with the motion track of the first touch control operation track, the method for described information processing also comprises:
Proofread and correct described i touch point, so that described electronic equipment does not respond described i touch point.
Concrete, after definite i touch point is offset point, the touch information of this i touch point is not processed, to reach the technique effect that does not respond i touch point, such as: the first touch control operation is that the carrying out of touch-display unit selected to operation, be not implemented as the selection operation of i touch point of offset point, again such as: the first touch control operation is the operation of editor's word, and the stroke that touch-display unit is not shown as i touch point of offset point operates.
For more clearly to allow the application person of an ordinary skill in the technical field can better understand the method for describing in above-described embodiment, in conjunction with user's concrete operations, the implementation procedure of whole method is introduced below:
In user's first hand, hold a panel computer, when user's first is by right finger, carry out slide from top to bottom on the touching display screen of panel computer time, panel computer can detect this slide, obtain the touch point positional information of all touch points of this slide, positional information based on all touch points is determined the motion track of slide
Further, panel computer can detect each touch point of motion track, to determine the offset point that exceedes permissible variation value in motion track, and proofread and correct the offset point determined, so that the motion track corresponding with slide that panel computer is finally presented on touching display screen is the track that does not comprise offset point, the motion track that allows user see is more level and smooth.
