The embodiment of the present invention provides a kind of display methods of touch track, as shown in figure 1, this method comprises the following steps：
101st, the touch point in current touch track set, predict in touch track set newest touch point it
N number of future position afterwards.
Wherein, current touch track set includes the current obtained all touches for being used to be formed a touch track
Point, N are more than or equal to 1.
Exemplary, above-mentioned touch point or future position are generally represented with a triple, such as：s1=(x1,y1,
t1), wherein, s1Represent touch point 1 or a future position 1, x1, y1Sat to be horizontal corresponding to touch point 1 or future position 1, vertical
Mark, t1For touch point 1 or the corresponding timestamp of future position 1.
All touches that current time in a touch track has obtained are stored in above-mentioned current touch track set T
Point.Based on this, T is represented by T=(s1,s2,…si…).Wherein, siRepresent the newest touch point that current time obtains.In addition,
After the period of (i.e. touch-control instrument leaves touch-screen) after lifting pen, the touch point in touch track set is not further added by.Its
In, an above-mentioned period is usually the time delay of the display touch point of touch screen.
In a kind of example, it can be realized by the trajectory predictions algorithm (GMTP) based on mixed Gauss model in step 101
The current touch track set of basis in touch point, predict N number of pre- after newest touch point in touch track set
Measuring point.Certainly, the above-mentioned trajectory predictions algorithm based on mixed Gauss model is only a kind of example, it is possible to use other tracks
Prediction algorithm realizes N number of future position after the newest touch point of prediction in step 101.Such as：Based on the continuous shellfish of trajectory time
The continuous path sequence prediction algorithm of this network of leaf.It should be noted that the above-mentioned trajectory predictions algorithm being mentioned to is existing skill
Art, repeat no more here.
Optionally, in order to while the writing experience of user is ensured, the fortune of the display device of touch track can be reduced
Row consumption, the distance between newest touch point and its previous touch point in can gathering in current touch track are more than the first threshold
In the case of value, then trigger the prediction in step 101.Wherein, if the newest touch point in the set of current touch track is with before
When the distance between one touch point is more than first threshold, represent that the writing speed of active user is fast so that touch-control instrument is touching
Touch point and the distance between the touch point of the newest display of touch-control person's handwriting touched on screen are excessive, influence user writing and experience.It is based on
This, above-mentioned steps 101 can be replaced following step：
Between 101a, the newest touch point in current touch track set and newest touch point previous touch point
Distance be more than first threshold in the case of, according to the touch point in current touch track set, predict touch track collection
N number of future position in conjunction after newest touch point.
Exemplary, when obtaining the 100th touch point in current touch track set, newest touch point is previous with it
The distance between individual touch point is more than first threshold first, then the touch point in being gathered according to current touch track, predicts tactile
Touch N number of future position after the 100th touch point in the set of track.
Exemplary, the distance between the 2 points public affairs in the distance between above-mentioned newest touch point and its previous touch point
Formula calculates, specifically：
Wherein, d represents the distance between newest touch point and its previous touch point；Ax, Ay represent newest touch respectively
The abscissa and ordinate of point；Bx, By represent the abscissa and ordinate of the previous touch point of newest touch point respectively.
It should be noted that those skilled in the art are it should be clearly understood that only working as increases new touch in touch track set
When touching, N number of future position after newest touch point in touch track set can be just predicted.
Optionally, in order to while the writing experience of user is ensured, the fortune of the display device of touch track can be reduced
Row consumption, also can be pre- in triggering step 101 in the case of M touch point is often increased in current touch track set
Survey.Based on this, step 101 can be replaced by following step：
101b, in the case of often increasing M touch point in current touch track set, according to current touch track
Touch point in set, predict N number of future position after newest touch point in touch track set.
For example, as M=5, then when the 5th touch point is obtained in current touch track set, predict the 5th and touch
N number of future position after touching a little；When increasing by 5 touch points again in touch track set, then current touch track
There are 10 touch points in set, according to the touch point in current touch track set, predict the 10th in touch track set
N number of future position after individual touch point.Wherein, M is less than or equal to N.
Optionally, in order to ensure the writing experience of user, and the operation of the display device of touch track is further reduced
Consumption.Step can be triggered on the basis of above-mentioned steps 101a, when often increasing M touch point in current touch track set
Prediction in rapid 101.Based on this, step 101 can be replaced following step：
Between 101c, the newest touch point in current touch track set and newest touch point previous touch point
Distance be more than first threshold, and in the case of often increasing M touch point in current touch track set, touched according to current
The touch point in the set of track is touched, predicts N number of future position after newest touch point in touch track set.Wherein, M is less than
Or equal to N.
102nd, on the basis of the touch track currently shown, show in N number of future position positioned at the touch rail currently shown
At least one future position after mark.
Exemplary, above-mentioned at least one future position is：Rear X future position in N number of future position.It is if specifically, N number of
It is during future position when future position is predicted for touch point first in touch track set, then above-mentioned at least one pre-
Measuring point is N number of future position.When touch point i.e. first in touch track set is predicted, X=N.And after this,
When i.e. N number of future position is not the future position when touch point first in touch track set is predicted, X=M.Wherein, M
Represent touch point in the set of current touch track compared to it is preceding be once predicted when touch track in increased touch point
Number, and M is less than or equal to N.
If for example, N=5, and when often increasing a touch point in touch track set (i.e. M=1), carry out once pre-
Survey.If the number of the touch point in the preceding touch track set being once predicted, which is 100, (obtains the in touch track set
Prediction is triggered when 100 touch points first), the touch point in touch track set predict future position 101 '-
105’.Because the touch track currently shown is the touch track that preceding 100 touch points are formed, therefore, by what is predicted first
Future position 101 ' -105 ' is all shown.And the number of the touch point in current touch track set is 101, then basis is worked as
Touch point in preceding touch track set predicts the 102nd " -106 " individual future position.Due in current touch track set
Touch point adds a touch point compared to the touch point in the preceding touch track set being once predicted, then by
102 " -106 " rear 1 future position in individual future position is shown, i.e., is shown 106 ", is particularly shown as shown in Figure 2.
Optionally, because the future position predicted according to touch point can not accurately represent real touch point, because
After this step 102, in addition to future position is modified.And future position is modified including following two ways, specifically
's：
Mode one：
102a1, after a touch point corresponding to each future position is got, calculate respectively each future position with it is corresponding
Touch point between position deviation.
Exemplary, during future position 101 ', then touch point corresponding to future position 101 ' is the 101st in touch track set
Individual touch point.
Exemplary, above-mentioned position deviation can be represented with the distance between 2 points.Specifically：
Wherein, RMSE represents position deviation, (x'i,y'i) represent future position transverse and longitudinal coordinate；(xi,yi) represent touch point
Transverse and longitudinal coordinate.
Exemplary, if N=5, M=3, and have 103 touch points in current touch track set, touched according to current
It is 104 ' -108 ' to touch track set to be predicted to obtain corresponding future position, and 3 future positions are shown by after.Afterwards, base
In above-mentioned steps 102a, when the 106th touch point (i.e. the first touch point 106) is obtained in touch track set, calculate and touch
Position deviation between point 106 and future position 106 '；When obtaining touch point 107 in touch track set, touch point 107 is calculated
Position deviation between future position 107 '；When obtaining touch point 108 in touch track set, calculate touch point 108 with it is pre-
Position deviation between measuring point 108 '.
If 102a2, position deviation are more than Second Threshold, the future position in the touch track of display is updated to corresponding
Touch point；Otherwise, the future position in the touch track of display is not updated.
It is exemplary, Second Threshold refer to future position can accurately represent corresponding to touch point when future position with
The critical value of position deviation between corresponding touch point.Specifically, if the position deviation in upper step 102a1 is more than Second Threshold
When, then it represents that future position can not accurately represent corresponding touch point.If be not more than Second Threshold, then it represents that future position can be accurate
Touch point corresponding to true representative.
Exemplary, based on above-mentioned steps 102a1, if touch point 106 and future position 106 ' in the set of current touch track
Between position deviation be more than Second Threshold, then the future position 106 ' shown in step 102 is updated to touch point 106.If touch
The position deviation touched a little between the position deviation between 107 and future position 107 ' and touch point 108 and future position 108 ' is little
It is constant in Second Threshold, the then future position 107 ', 108 ' shown in holding step 102.
Mode two：
102b1, after touch point corresponding to future position is got, calculate the integral position between future position and touch point
Deviation.
Exemplary, if N=5, M=3, and have 103 touch points in current touch track set, touched according to current
It is 104 ' -108 ' to touch track set to be predicted to obtain corresponding future position, and 3 future positions are shown by after.Afterwards, count
Calculate the 106th, 107,108 integral position between touch point and future position 106 ', 107 ', 108 ' in the set of current touch track
Deviation.
Exemplary, above-mentioned integral position deviation can be represented with root mean square formula.Specifically：
Wherein, RMSE represents integral position deviation, (x'i,y'i) represent future position transverse and longitudinal coordinate；(xi,yi) represent to touch
Touch transverse and longitudinal coordinate a little.For example, above-mentioned i values are 106-107.
If 102b2, integral position deviation are more than the 3rd threshold value, the future position in the touch track of display is updated to pair
The touch point answered；Otherwise, the future position in the touch track of display is not updated.
It is exemplary, the 3rd threshold value refer to future position can accurately represent corresponding to touch point when future position with
The critical value of position deviation between corresponding touch point.Specifically, if the position deviation in upper step 102b1 is more than the 3rd threshold value
When, then it represents that future position can not accurately represent corresponding touch point.If be not more than Second Threshold, then it represents that future position can be accurate
Touch point corresponding to true representative.
Exemplary, based on above-mentioned steps 102b1, touch point 106,107,108 and prediction in the set of current touch track
Integral position deviation between point 106 ', 107 ', 108 ' is more than the 3rd threshold value, then by the touch track shown in step 102
Future position 106 ', 107 ', 108 ' be updated to touch point 106,107,108.Otherwise, the touch rail shown in step 102 is kept
Future position 106 ', 107 ', 108 ' in mark is constant.
Optionally, truly touched corresponding to touch-control instrument in order to which the touch track for ensureing currently to show can really reflect
Track is touched, then the future position in the touch track for needing currently to show is updated to its corresponding touch point.Based on this, step
Also comprise the following steps after 102：
102c, after the first touch point corresponding to future position is got, by the touch track of display future position update
For corresponding touch point.
In a kind of specific embodiment, as shown in figure 3, obtain first in current touch track newest touch point with before it
One touch point, and distance between the two is calculated, and judge whether the distance is more than first threshold；If it is not, then touch track
Display device only show touch point in touch track set；If so, the then touch point prediction in touch track set
The N number of future position gone out after newest touch point, and be located in the touch track currently shown in the N number of future position of increase display and work as
Future position after the touch track of preceding display；After touch point corresponding to each future position is obtained, comparison prediction point and its
Position deviation between corresponding touch point；When position deviation is more than Second Threshold, future position is updated to touch point, otherwise
Without renewal.
