Equipment, the application are not especially limited.
Below in conjunction with the accompanying drawings, technical scheme is described in detail, as shown in figure 1, the side of the information processing
Method comprises the following steps：
S10：Detect whether the first slide be present on the touch control display；
In specific implementation process, first slide formed trace graphics can be it is a variety of, such as：It can be shape
Into circle or oval, or it is straight line etc..
Then S20 is performed：When detecting the presence of first slide, first slide is responded, is obtained
The first position information of first touch point of first slide on the touch control display.
In a particular embodiment, when detecting above-mentioned track, e.g. smooth curve, opened from first point of touch-control
Beginning, the scanning touch-display unit based on a predeterminated frequency one by one, until detecting the first touch point, specific principle is,
Using X-axis, Y-axis cross-distribution as capacitance matrix, when finger touches screen, can be detected tactile by X, the scanning one by one of Y-axis
The change of position electric capacity is controlled, so as to calculate the positional information where first touch point.
For example, give Y-axis to apply driving voltage first, 5V in this way, when the voltage for detecting X-axis reduces, if with Y-axis pair
When the voltage for the X-axis answered is less than 5V, then, the position where the point is exactly the position of touch point.
After the detection of the first touch point on the track, S30 is performed：Based on the first position information, first is determined
Preset range, wherein, the area of the first preset range is less than the area of the touch control display.
In a particular embodiment, the positional information of specific touch point, example are determined by the touch point of above-mentioned determination
Such as, the first position information of the touch point is a coordinate information P（1.6,2.8）, can be by touching for the regulation of the origin of coordinates
The central point for controlling display screen determines, or is determined by the lower left corner of touching display screen for origin.Certainly, by different seats
It is also different that origin, which is marked, come the coordinate of the first position information of the touch point determined.So the application not to this first touch
The coordinate convention for controlling the positional information of point specifically limits.
It is determined that after the information of first position, based on the positional information, to determine the first preset range.The preset range is
A range areas smaller than the display screen, in a particular embodiment, the preset range can be with first touch-control
The coordinate position point of point is the scope of the circle of origin, and the wherein radius of the circle can be 1 unit length, or 2 unit length
Degree etc., in the default scope, can specifically include at least five touch point, be, for example,（X1, Y1）,（X2, Y2）,（X3, Y3）,
（X4, Y4）,（X5, Y5）；Can also be the square area put centered on the coordinate position point of first touch point, should
Preset range equally also includes at least five touch point.Certainly, the division in this application for the preset range is not limited in
Division methods mentioned above, can also be Delta Region, or region of long strip type etc., not do in this application specific
Limit.
After the first preset range is determined, S40 is performed：In the first preset range, detect whether there is described
Second touch point of one slide on the touch control display.
Wherein, after second touch point is detected, the second place information of second touch point is obtained；Based on this second
Positional information, the second preset range is determined, wherein the area of the second preset range is less than the area of the touch control display, and second
Preset range on the touch control display corresponding second area with the first preset range in the touch control display corresponding first
Region is different region.
In a particular embodiment, when detecting the presence of on first slide in the first default scope
After two touch points, following step is the same with S30, and the second preset range is determined according to second place information.This
Two preset ranges can have portion based on same range size, the second preset range with the first preset range with the first preset range
Divide overlapping region, still, there must be nonoverlapping region, for detecting the particular location of the second touch point.
First when detecting the second touch point based on the first preset range, the setting of the preset range can have two kinds of settings
Method：
The first, the capacitance matrix that point is intersected to form by N bars X-axis and N bar Y-axis centered on the first touch-control dot position information
Point, N values can flexibly be set, and the scope of capacitance matrix point is in the range of touch-display unit.
Second point, centered on the first touch-control dot position information, L is the capacitance matrix in a round scope of radius setting
Point, L values can flexibly be set, and the scope of capacitance matrix point is in the range of touch-display unit.
The touch-control dot position information of the embodiment of the present application pair first touch point of determination by taking first method as an example, such as：
Preset range N is equal to 5, and the positional information of first touch point is C (x, y), then the capacitance matrix point such as following table of preset range：
| 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 the range of N is equal to 5, a driving voltage is applied to the Y direction of each point in upper table, because screen
The difference of size etc., the driving voltage of application also differ, so, the embodiment of the present application is not restricted to driving voltage value.Example
Such as：The driving voltage of application is 5V, then, inductive voltage value is read in X-direction, when the inductive voltage value and driving that read
Voltage is identical or approximately the same, then the point is not touch point, when the inductive voltage value of reading is with driving voltage difference, it is determined that
The point is second touch point, such as：Except the inductive voltage value of point C (x-1, y+1) X-direction is not equal to outside 5V, in the range of
Remaining each point is 5V in the inductive voltage value of X-direction, it is thus determined that C (x-1, y+1) X is second touch point.
After the positional information of the second touch point is determined, according to the positional information of the second touch point, to determine second
Preset range, such as above two mode establishing method, no longer it is described in detail here.
It is above-mentioned that the second touch point is detected the presence of in the first preset range, however, not examined in the first preset range
When measuring the second touch point, it is necessary to carry out full screen scanning to the touch-display unit, detect whether that having described first slides
Operational 3rd touch point.
In a particular embodiment, when not detecting the second touch point in the first preset range, with detection first
The method of touch point is identical, full screen scanning, detects the position of the 3rd touch point, identical with step S20, by X, Y-axis one by one
Scanning, to detect after Y-axis applies driving voltage, whether the voltage of X-axis has reduction, if reducing, then it is assumed that, the voltage
The point of reduction is also a touch point, and simply, the point can still be examined not on the track of the slide by electronic equipment
Measure and, so as to export the track of the touch point.
After the second touch point having been detected in above-mentioned first preset range, so that it is determined that after the second preset range,
This method also includes：In the second preset range, detect whether the 4th of the first slide on the touch control display be present
Touch point；When four touch points be present, the first slide is responded, at least based on the first, the second and the four touch point, really
Fixed the first track corresponding with the first slide.
In specific implementation process, according to the first touch point, preset range is determined, is detected whether in the preset range
The track of subsequent point be present, so can draw at least a bit of arc length by 1 points, then further according to these three points
In that point for finally determining delimit default scope, to determine the position of next point, one is drawn so as to which the rest may be inferred
Track, the track are the trace graphics that smooth straight line or curve are formed.
In a particular embodiment, as the circle drawn with writing pencil on screen, started writing in starting point
When, the electronic equipment can predict the position that subsequent point occurs, so that after determining subsequent point in default scope, then
Again preset range delimited, so, judges to whether there is the touch point of subsequent point, the track that will entirely enclose in preset range successively
Display, export to user, then user it can be seen that be exactly a circle figure.
It is determined that after the first track corresponding with first slide, this method also includes：Periodically to touch-control
Display carries out full screen scanning, whether there is the 5th touch point on touch control display with detection；When five touch points be present,
Output includes the second track of the 5th touch point.
In a particular embodiment, after the first track is obtained, in order to avoid missing others on the display screen
Point, a cycle time is preset, e.g. 5 seconds, within the time of 5 seconds, is scanned, has been detected whether except track to full frame
Outside other tracing points.Certain default time can also be others such as, 3 seconds, 4 seconds etc..Do not do in this application
It is specific to limit.Full frame scanning is carried out once to the display screen every the default time, compared to touching on detection track
The time of control point is longer, for example, needed to detect the position of the first touch point on track within 1 second time, and in the step
In rapid, the point missed is detected whether by default longer time, so, beneficial to the speed of response.
Certainly, can also be by interleaved mode, every a line when whether having the point missed on detecting display screen
Either it is scanned every two rows, can so saves the consumption power of half or more consume power.
For example after trace graphics are obtained, scanning for the first time can be the scanning in T time in every line, the
Rescan can be that third time scanning can be every the scanning of three rows in T time every the scanning of two rows in T time
Etc., so it is prevented that missing other touch points on screen, while so scanning can save the power of consumption.
It is more clearly to allow the application person of an ordinary skill in the technical field to be best understood from above-mentioned implementation below
Method described in example, the implementation process of whole method is introduced with reference to the concrete operations of user：
A tablet personal computer is held in user's first hand, when user's first is by the middle finger of the right hand, is shown in the touch-control of tablet personal computer
When carrying out slide in display screen from top to bottom, when finger contacts touching display screen, first touch point is detected first, is connect
, by searching the second touch point for operating of user's finger in the first preset range region of the first touch point, then, then delimit the
Two preset ranges, the 3rd touch point is searched in second preset range, is searched successively, so as to form the rail of user's finger slip
Mark, certainly, during user's finger forms track on touching display screen, the touch point not on track is still had,
Namely user has other operations again outside track to touch control display, and at this moment, touch control display can be also responded outside the track
Operation.After user shows the track of the slide completely, every in some cycles sweep time, if do not had
Touch point has been detected, then can reduce the frequency of scanning, so as to drop low consumed power, if having detected touch point,
The operation of the touch point is exported simultaneously.
