According to, the wire rod touch data is such as abandoned, application layer is not reported, alternatively, counted, study sampled targets team for identification
The parameter of column, sampled targets point and wire rod touch data.
It should be noted that can directly carry out wire rod touch-control to every frame touch data for the touch data detected
Data detection (i.e. step 102- step 104) also can decide whether to meet preset condition, such as whether access earphone cable,
The wire rods such as USB (Universal Serial BUS, universal serial bus) data line, if meeting the condition, at this point, have can for wire rod
Energy touch screen then carries out detection (i.e. step 102- step 104), etc., the embodiment of the present invention of wire rod touch data to touch screen
It is without restriction to this.
In embodiments of the present invention, touch data is acquired, there are multiple sampled points in the touch data, selected from sampled point

Because reporting wire rod touch data to execute touch control operation, to avoid maloperation.
Referring to Fig. 2, the step flow chart of the processing method of another touch data of one embodiment of the invention is shown,
It can specifically include following steps:
Step 201, touch data is acquired.
Wherein, there are multiple sampled points in touch data.
Referring to Fig. 3 A to Fig. 3 D, a kind of exemplary diagram of touch data of one embodiment of the invention is shown.
In Fig. 3 A to Fig. 3 D, each numerical value is the position represented where collection point, also represents the collection point
Diff (sampling changing value).
The touch data that Fig. 3 A is triggered by user's finger touching touch screen, the collection point touched by user's finger
Diff is square or round (i.e. boxed area in Fig. 3 A), also, the trend that numerical value is reduced with some central point to surrounding is bright
Aobvious, i.e., data variation is larger.
Fig. 3 B- Fig. 3 D is touched the touch data of triggering touch screen by wire rod, the collection point touched by user's finger
Diff, it is linear to arrange (i.e. boxed area in Fig. 3 B- Fig. 3 D), also, numerical value is become with some central point to what surrounding reduced
Gesture is unobvious, i.e., data variation is smaller.
Step 202, the sampling changing value of the multiple sampled point is compared.
Step 203, the corresponding sampled point of the maximum sampling changing value of selective value, as sampling central point.
In embodiments of the present invention, the comparison that sampling changing value can be carried out to the sampled point in a frame touch data, from
The middle maximum sampling changing value of selective value is selected the sampling maximum sampled point of changing value, is set as sampling central point.
Certainly, other than being worth the corresponding sampled point of maximum sampling changing value, other sampled point conducts can also be used
Central point is sampled, for example, carrying out denoising to touch data, the maximum sampling changing value of value is likely to be noise and is dropped,
At this point, the corresponding sampled point of the sampling changing value such as the second height of selective value, third height is as sampling central point, the embodiment of the present invention pair
This is without restriction.
Step 204, the first ratio, the second ratio are taken respectively on the basis of the sampling changing value of the sampling central point,
Obtain the first change threshold, the second change threshold.
By the sampling changing value for sampling central point multiplied by the first ratio, the first change threshold can be obtained.
By the sampling changing value for sampling central point multiplied by the second ratio, the second change threshold can be obtained.
Wherein, the first ratio is greater than the second ratio, also, the first ratio and the second ratio are respectively less than 1.
Therefore, the first change threshold is greater than the second change threshold, also, the first change threshold and the second change threshold are small
In the sampling changing value of sampling central point.
Step 205, if comprising the first candidate sampled point, quantity more than preset first number in the sampled point of a certain row or column
Measure the second candidate sampled point of threshold value, it is determined that the row described is classified as effective sampled targets queue.
Wherein, the first candidate sampled point is the sampled point for sampling changing value and being greater than the first change threshold.
Second candidate sampled point is that sampling changing value is greater than the second change threshold and is less than or equal to the first change threshold
Sampled point.
In embodiments of the present invention, the sampled point for traversing certain frame touch data is sampled changing value and the first variation threshold
Value is compared, if the sampling changing value of some sampled point is greater than the first change threshold, is marked as the first candidate and is adopted
Sampling point.
In turn, the sampled point in row or column locating for the candidate sampled point of traversal first, is sampled becoming with first for variation
Change threshold value, the second change threshold to be compared, if the sampled value of sampled point is greater than the second change threshold and is less than or equal to the
One change threshold, then by the candidate sampled point of its label second.
If the quantity of certain row or certain candidate sampled point of column upper second is more than preset first amount threshold, can determine
The row or this be classified as effective sampled targets queue.
For example, setting sampling central point as A, the first ratio is 0.8, and the second ratio is 0.2, is changed using diff as sampling
Value, then the sampling changing value of A is expressed as diff (A), and the first change threshold is 0.8*diff (A), and the second change threshold is 0.2*
diff(A)。
When traversing sampled point X, diff value is expressed as diff (X), if diff (X) > 0.8*diff (A), and X is expert at
There is the diff value of the point of 8 (the first amount threshold) or more to be greater than 0.2*diff (A) on (or column), also, is less than or equal to
0.8*diff (A), then the row where X (or column) is referred to as effective sampled targets queue.
Step 206, the first multiple is taken respectively on the basis of the sampling changing value of the sampling central point, obtain third and become
Change threshold value.
Step 207, if the sampling changing value of a certain sampled point is greater than the third change threshold, it is determined that the sampled point
For effective sampled targets point.
In embodiments of the present invention, the sampling changing value for sampling central point be can be obtained into third change multiplied by the first multiple
Change threshold value.
Wherein, third change threshold is less than 1.
The sampled point for traversing certain frame touch data is sampled changing value and is compared with third change threshold, if certain
The sampling changing value of a sampled point is greater than third change threshold, then is marked as effective sampled targets point.
Step 208, judge the sampling central point whether wire rod sampling variation range in and the sampling center
Point, the sampled targets queue and the sampled targets point whether linear array；If so, thening follow the steps 209.
Step 209, determine that the touch data belongs to the wire rod touch data of wire rod triggering.
In practical applications, it can be directed to the characteristic of wire rod, the range of the lower sampling changing value composition of a value is set,
Variation range is sampled as wire rod.
The sampling changing value for sampling central point and wire rod sampling variation range are compared, and, to sampling central point,
Arranging situation between sampled targets queue and sampled targets point is analyzed.
If sampling the sampling changing value of central point in wire rod sampling variation range and sampling central point, sampling mesh
Mark queue and sampled targets point whether linear array, then can determine that the touch data of present frame belongs to the wire rod touching of wire rod triggering
Control data.
In one embodiment of the invention, step 208 may include following sub-step:
Sub-step S11 inquires preset report point threshold value.
Sub-step S12 takes the second multiple, third multiple respectively on the basis of the report point threshold value, obtains wire rod report point
Lower limit value, wire rod report point upper limit value.
Sub-step S13, judge it is described sampling central point sampling changing value whether be located at the wire rod report point lower limit value with
Between the wire rod report point upper limit value；If so, sub-step S14 is executed,
Sub-step S14 determines the sampling central point in wire rod sampling variation range.
In the concrete realization, one report point threshold value, i.e. the sampling changing value of some sampled point can be set for touch screen
Greater than the report point threshold value, it may be considered that there is the possibility of touching, and and it is non-noise.
It should be noted that the hardware feature of different touch screens is not had to, set report point threshold value is also different,
The embodiments of the present invention are not limited thereto.
It can be obtained wire rod report point lower limit value by report point threshold value multiplied by the second multiple for the characteristic of wire rod, by report point threshold
Value can be obtained wire rod report point upper limit value multiplied by third multiple.
The sampling changing value for sampling central point is compared with wire rod report point lower limit value with wire rod report point upper limit value, if
The sampling changing value of central point is sampled between wire rod report point lower limit value and wire rod report point upper limit value, then can determine sampling center
Point is in wire rod sampling variation range.
Wherein, the second multiple and third multiple are greater than 1, i.e., on the basis of report point threshold value, float lesser value, is set as
Wire rod samples variation range.
Under normal circumstances, wire rod report point upper limit value is less than finger report point lower limit value.
The finger report point lower limit value is the characteristic for user's finger, by report point threshold value multiplied by a certain multiple number obtained
Value.
For example, it is assumed that sampling central point is A, report point threshold value is Limit, and the second multiple is 1.2, and third multiple is 3, with
Diff is expressed as diff (A) as sampling changing value, the sampling changing value of A, and wire rod report point lower limit value is 1.2*Limit, wire rod
Report point upper limit value is 3*Limit, if 1.2*Limit < diff (A) < 3*Limit, is changed it may be considered that A is sampled in wire rod
In range.
In another embodiment of the present invention, step 208 may include following sub-step:
Sub-step S21 is counted in the sampling queue locating for the sampling central point and adjacent sampling queue, described is adopted
The quantity of sample target point.
Sub-step S22 judges whether the sampled targets queue and sampling queue locating for the sampling central point are adjacent
Or it is identical, also, whether the quantity is more than preset second amount threshold；If so, executing sub-step S23.
Sub-step S23 determines the sampling central point, the sampled targets queue and the sampled targets point linear rows
Column.
In embodiments of the present invention, if sampled targets queue is in the presence of (i.e. quantity is greater than or equal to 1), sampled targets queue
With sampling central point locating for sampling queue (row or column) it is adjacent or identical, also, sample central point locating for sampling queue with
The quantity of sampled targets point is more than the second amount threshold (such as 5) in adjacent sampling queue (row or column), this can determine sampling
Central point, sampled targets queue and sampled targets point linear array.
It should be noted that so-called adjacent, the number of queues that is spaced between two sampling queues can be referred in the range of setting
It is interior, under normal circumstances, two 0, sampling queue interval row or column, but it is also possible to it is spaced 1 row or column, 2 row or column, etc.
