Specific implementation mode
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
In order to solve the above-mentioned technical problem, the embodiment of the present disclosure provides a kind of method for correcting coordinate, and this method can be used for
In coordinates correction program, system or device, the program, system or device can further apply the electronic equipment with Trackpad
(in some electronic equipments, the Trackpad can be combined with display screen, and composition has both touch-control and the touch screen of display function).
As shown in Figure 1, the method comprising the steps of S101 to step S103：
In step S101, the first coordinate information every do-nothing operation on the touch pad is obtained；
In step s 102, it when the corresponding next operation of do-nothing operation is touch operation, obtains touch operation and is touching
Control the second coordinate information on plate；
First coordinate information is the coordinate of x-axis and y-axis in do-nothing operation is relative to three-dimensional system of coordinate where Trackpad,
In, theoretically, the x-axis and y-axis are respectively parallel to two axis of the two-dimensional coordinate system based on plane where Trackpad, and the three-dimensional
(only the origin of the three-dimensional system of coordinate may be also less accurate in same vertical line for the origin of coordinate system and the two-dimensional coordinate system
Really)；And abscissa and ordinate of the second coordinate information, that is, touch operation in the two-dimensional coordinate system of plane where Trackpad.
In step s 103, the second coordinate information is compared with the first coordinate information, and is determined according to comparison result
Whether the first coordinate information is corrected.
After getting every do-nothing operation the first coordinate information on the touch pad, if every the corresponding next behaviour of do-nothing operation
As touch operation, illustrate that touch control object is carrying out electronic equipment to touch Trackpad immediately again after do-nothing operation, i.e. the touch-control
Operation to touch flashy touch-control before Trackpad (or last before contact Trackpad/have recently detected every do-nothing operation), and
In principle, the touch operation that the first coordinate information detected in a flash before touching Trackpad should in a flash be detected under
Second coordinate information is of substantially equal, thus, the second coordinate information can be compared with the first coordinate information, and tied according to comparing
Fruit determines whether to be corrected the first coordinate information, to the coordinate every do-nothing operation that is detected in a flash before touch due to
Touch Trackpad front and rear coordinate can occur the factors such as saltus step and it is inaccurate when, can in time and accurately to the coordinate every do-nothing operation into
Row correction.
Such as：When being detected every do-nothing operation and touch operation according to certain frequency f (time interval 1/f), each grasped every sky
The first coordinate information made is preceding (the last one time interval before touching, it is herein assumed that touch in a flash touched every time
The last one time interval before touching is i-th of time interval) suspension touch control coordinate (i.e. finger is before touching Trackpad
In a flash relative to the projection coordinate of Trackpad), and if every do-nothing operation it is corresponding it is next operation be touch operation, the touch
Second coordinate information of operation is the coordinate for the touch signal that i+1 interval detection arrives, and the i+1 time interval
May just be user it is practical touch at that moment or touch after in a flash.
As shown in Fig. 2, in one embodiment, above-mentioned step S103 shown in FIG. 1, i.e., by the second coordinate information and first
Coordinate information is compared, and determines whether to be corrected the first coordinate information according to comparison result, may include：
In step A1, when do-nothing operation includes multiple, calculate separately it is multiple every in do-nothing operation respectively every the of do-nothing operation
Coordinate difference between one coordinate information and corresponding second coordinate information；Wherein, respectively every the first coordinate information of do-nothing operation and its
Second coordinate information of adjacent next touch operation is corresponding；
Such as：I-th is being detected after do-nothing operation, the next operation detected be touch operation after, then it is aforementioned touch
It is exactly with i-th every the adjacent next touch operation of do-nothing operation to touch operation, i-th of the first coordinate information every do-nothing operation and before
The second coordinate information for stating touch operation is corresponding.
In step A2, according to respectively every the corresponding coordinate difference of do-nothing operation, it is determined whether to multiple every the of do-nothing operation
One coordinate information is corrected.
When do-nothing operation includes multiple, respectively the first coordinate information every do-nothing operation can be calculated separately and sat with corresponding second
The coordinate difference between information is marked, and then based on respectively every the corresponding coordinate difference of do-nothing operation, it is determined whether to multiple every do-nothing operation
The first coordinate information be corrected, the factors such as saltus step occur due to touching Trackpad front and rear coordinate in the coordinate every do-nothing operation
And when inaccurate, accurately the coordinate every do-nothing operation can be corrected in time, and then avoids due to the coordinate every do-nothing operation
Normal realization that is inaccurate and influencing corresponding function.
In one embodiment, above-mentioned step A2 shown in Fig. 2, i.e., according to respectively every the corresponding coordinate difference of do-nothing operation,
Determine whether to be corrected every the first coordinate information of do-nothing operation to multiple, can be performed as：
A211, when multiple every in do-nothing operation, the number ratio shared by do-nothing operation that coordinate difference is more than preset coordinate difference is more than
When the first preset ratio, determination is corrected multiple the first coordinate informations every do-nothing operation.
When multiple every in do-nothing operation, the number ratio shared by do-nothing operation that coordinate difference is more than preset coordinate difference is more than first pre-
If when ratio, illustrating multiple every having more the first coordinate information every do-nothing operation and corresponding second coordinate information in do-nothing operation
Difference it is larger, i.e., the coordinate information deviation of the more coordinate information every do-nothing operation touch operation adjacent thereto is larger, says
It is bright to cause the coordinate information every do-nothing operation inaccurate due to touching the factors such as Trackpad front and rear coordinate generation saltus step, thus, it needs
Multiple the first coordinate informations every do-nothing operation are corrected, to ensure the coordinate accuracy every do-nothing operation, and then be ensured
To the accurate response every do-nothing operation.
Optionally, multiple every in do-nothing operation, coordinate difference is more than the number ratio shared by the do-nothing operation of preset coordinate difference, can press
It is determined according to following steps：
Whether each every do-nothing operation corresponding coordinate difference more than preset coordinate poor, it is super then to count coordinate difference if first judging respectively
The number n every do-nothing operation and the total number N every do-nothing operation for crossing preset coordinate difference calculate above-mentioned number ratio k=n/N, finally sentence
Whether big first preset ratios of disconnected above-mentioned number ratio k.
First preset ratio can be with personal settings, such as can be 50% or 80%.
Finally, multiple every do-nothing operation can be three or more every do-nothing operation, such as can be four every do-nothing operation, and each
Every the corresponding next operation of do-nothing operation be touch operation, and respectively can be identical relative to the height of Trackpad every do-nothing operation
It can also be different, it is preferable that roughly the same.
In one embodiment, above-mentioned step A2 shown in Fig. 2, i.e., according to respectively every the corresponding coordinate difference of do-nothing operation,
Determine whether to be corrected every the first coordinate information of do-nothing operation to multiple, can be performed as：
A221, basis respectively every the corresponding coordinate difference of do-nothing operation, obtain comprehensive coordinate difference；
Wherein, comprehensive coordinate difference is each synthesis every the corresponding coordinate difference of do-nothing operation being calculated by preset algorithm
Value is used for the multiple grid deviation situations every do-nothing operation of comprehensive assessment.Such as：Comprehensive coordinate difference can be respectively every do-nothing operation point
The weighted average of not corresponding coordinate difference, it is respectively right respectively every do-nothing operation respectively every the variance of the corresponding coordinate difference of do-nothing operation
The difference of two squares etc. for the coordinate difference answered.
A222, judge whether comprehensive coordinate difference is more than preset coordinate threshold value, and be more than pre- in the comprehensive coordinate difference
If when coordinate threshold value, determination is corrected multiple the first coordinate informations every do-nothing operation,
Wherein, preset coordinate threshold value personalizable is set, such as can be 0.2 centimetre, 0.1 centimetre.
In the present embodiment, when determining whether to be corrected the first coordinate information, according to respectively being corresponded to respectively every do-nothing operation
Coordinate difference, obtain comprehensive coordinate difference, and then when comprehensive coordinate difference is more than preset coordinate threshold value, determine to multiple every sky
First coordinate information of operation is corrected, in this way, both accurately the coordinate every do-nothing operation can be corrected in time,
Frequently correction be can avoid again every the coordinate information of do-nothing operation.
In one embodiment, above-mentioned step A2 shown in Fig. 2, i.e., according to respectively every the corresponding coordinate difference of do-nothing operation,
Determine whether to be corrected every the first coordinate information of do-nothing operation to multiple, can be performed as：
S231, according to it is described respectively judge every the corresponding coordinate difference of do-nothing operation described be every the grid deviation direction of do-nothing operation respectively
It is no consistent；
In the present embodiment, for any every do-nothing operation, grid deviation direction includes：Believe relative to second coordinate
Breath, the abscissa of corresponding first coordinate information is bigger than normal, abscissa is less than normal, ordinate is bigger than normal or ordinate is less than normal.
Assuming that any every do-nothing operation Pi1The first coordinate information include should every do-nothing operation Pi1Abscissa xi1And ordinate
yi1, it is denoted as (xi1, yi1), it should be every do-nothing operation Pi1Corresponding next touch operation Pi2The second coordinate information include the touch behaviour
The abscissa x of worki2With ordinate yi2, it is denoted as (xi2, yi2), then it should be every do-nothing operation Pi1Corresponding coordinate difference △iIt can be expressed as：
△i=(xi1-xi2, yi1-yi2)；The judgment rule in the grid deviation direction every do-nothing operation could be provided as：
If xi1-xi2＞ 0, then judgement should be every do-nothing operation Pi1Abscissa it is bigger than normal；
If xi1-xi2＜ 0, then judgement should be every do-nothing operation Pi1Abscissa it is less than normal；
If yi1-yi2＞ 0, then judgement should be every do-nothing operation Pi1Ordinate it is bigger than normal；
If yi1-yi2＜ 0, then judgement should be every do-nothing operation Pi1Ordinate it is less than normal.
A232, when multiple every in do-nothing operation, the consistent number shared by do-nothing operation in grid deviation direction is preset than second
Ratio, and the grid deviation direction it is consistent when the corresponding coordinate difference of do-nothing operation is all higher than preset coordinate difference, determine to institute
Multiple the first coordinate informations every do-nothing operation are stated to be corrected.
If multiple numbers every do-nothing operation shared by consistent every grid deviation direction in do-nothing operation than the second preset ratio, and
The grid deviation direction it is consistent to be all higher than preset coordinate every the corresponding coordinate difference of do-nothing operation poor, then illustrate multiple every do-nothing operation
In have that the more coordinate every do-nothing operation is bigger than normal or less than normal compared to the coordinate of next touch operation adjacent thereto, and
Deviation is larger, further relates to multiple coordinates every do-nothing operation obviously less accurately, needs to multiple the first coordinates every do-nothing operation
Information is corrected, so as to be accurately corrected in time to the coordinate every do-nothing operation.
Such as：Can directly using every corresponding second coordinate value of do-nothing operation as its correction after the first coordinate value.
In another example：It next is touched compared to adjacent thereto every the more abscissa every do-nothing operation in do-nothing operation when multiple
The abscissa for touching operation is bigger than normal and poor more than preset coordinate, then turns all abscissas every do-nothing operation down, similarly,
When it is multiple every the more ordinate every do-nothing operation in do-nothing operation compared to next touch operation adjacent thereto
Ordinate it is less than normal i.e. be less than preset coordinate it is poor, then all ordinates every do-nothing operation are tuned up.
In one embodiment, method further includes：
When determination is corrected the first coordinate information, directly using second coordinate information as first after correction
Coordinate information；Or
When determine the first coordinate information is corrected when, according to being averaged for the first coordinate information and the second coordinate information
Value, is corrected the first coordinate information.
The above-mentioned average value according to the first coordinate information and the second coordinate information is corrected the first coordinate information, tool
Body may include：Directly using former mean values as correction after the first coordinate information, or by former mean values with original first
The weighted sum of coordinate information is as the first coordinate information after correction, or by the weighting of former mean values and the second coordinate information
With as the first coordinate information after correction.
Certainly, when do-nothing operation includes multiple, if it is determined that need to respectively every the first coordinate information of do-nothing operation into
Row correction, then respectively can be corrected every the first coordinate information of do-nothing operation according to above-mentioned steps.
In one embodiment, method further includes：
After being corrected to the first coordinate information, to the first coordinate information reference two-dimensional coordinate system coordinate origin into
Row is corrected.
It, can be to the coordinate origin of the three-dimensional system of coordinate of the first coordinate information foundation after being corrected to the first coordinate information
It is modified, the X-axis and Y-axis of the three-dimensional system of coordinate are parallel to Trackpad, i.e. (wherein, O is coordinate to the XOY of X-axis and Y-axis composition
Origin) face where face and Trackpad is parallel (in addition, the third axis Z axis of the three-dimensional system of coordinate is used for perpendicular to plane where Trackpad
Characterize the vertical height every do-nothing operation to Trackpad), and the origin of the three-dimensional system of coordinate may be inaccurate, thus, gradually right
After first coordinate information is corrected, which can be finely adjusted, it is equal to avoid the first coordinate information subsequently measured
It is less accurate.
It is, of course, also possible to preserve the first front and back coordinate information of correction, using as work log etc..
The embodiment of the present invention is described further below in conjunction with Fig. 3：
Such as：When it is multiple every do-nothing operation be respectively A (x1, y1), B (x2, y2), C (x3, y3), D in the subpoint of Trackpad
(x4, y4), and detecting next touch operation for respectively being detected successively after do-nothing operation touch point on the touch pad point
Not Wei A ' (x1 ', y1 '), B ' (x2 ', y2 '), C (x3 ', y3 '), D ' (x4 ', y4 ') when, then calculate separately A (x1, y1) and A '
(i.e. B points correspond to the coordinate difference of the coordinate difference (i.e. the corresponding coordinate difference of A points) of (x1 ', y1 '), B (x2, y2) and B ' (x2 ', y2 ')
Coordinate difference), the coordinate difference (i.e. the corresponding coordinate difference of C points) of C (x3, y3) and C (x3 ', y3 '), D (x4, y4) and D ' (x4 ',
Y4 ') coordinate difference (i.e. the corresponding coordinate difference of D points), and then respectively according to above-mentioned four be calculated coordinate difference, it is determined whether
The coordinate of four four subpoints --- A, B, C and D --- every do-nothing operation on the touchscreen is corrected.
Specifically, it is assumed that the first preset ratio be 70%, then in tetra- subpoints of A, B, C and D, if there are three or four
It is poor (such as 0.5 centimetre) that the corresponding coordinate difference of a subpoint is all higher than preset coordinate, it is determined that needs to tetra- projections of A, B, C and D
The coordinate of point is corrected, can also be into one after completing to the correction of A, B, C and D tetra- subpoints pair, four subpoints
Step is corrected the origin of two-dimensional coordinate system based on four subpoints.Or
A comprehensive coordinate difference is obtained according to the corresponding coordinate difference of tetra- subpoints of A, B, C and D, such as this four seats
The average coordinates difference of difference is marked, if the average coordinates difference is more than preset coordinate threshold value, it is determined that need to A, B, C and D tetra-
The coordinate of a subpoint is corrected；Equally, after completing to the correction of A, B, C and D tetra- subpoints pair, four subpoints,
Further the origin of two-dimensional coordinate system based on four subpoints can also be corrected.Or
Assuming that the second preset ratio is also 70%, if then in tetra- subpoints of A, B, C and D there are three or four subpoints
The abscissa of the projection coordinate of the abscissa next touch operation adjacent compared to its is bigger than normal, then explanation has more coordinate
Bias direction is unanimously that abscissa is bigger than normal, then turns the abscissa of tetra- subpoints of A, B, C and D down.
