Detailed description of the invention
Hereinafter, will be described in detail with reference to the accompanying drawings embodiments of the invention.
First, with reference to Fig. 1, display packing according to a first embodiment of the present invention will be described.According to the present invention
The display packing of first embodiment can be applicable to any electronic equipment including touch sensitive display unit.Such
The example of electronic equipment includes having and touches the smart mobile phone of display screen, has and touch the display of display screen and set
Standby etc..Below by with have touch display screen smart mobile phone be described as an example.
Fig. 1 is the flow chart of display packing according to a first embodiment of the present invention.
Display packing according to first embodiment includes:
Step S101: with predetermined time interval detection to the shifting of the object of display on described touch sensitive display unit
Dynamic operation, sequentially to obtain the position data of multiple touch location point.
In this step, by sensor etc. built-in in equipment, detect described with predetermined time interval
The mobile operation of the object of display on touch sensitive display unit, sequentially to obtain the position of multiple touch location point
Put data, say, that the plurality of touch location point is according to described mobile behaviour at each detection time point
Make what detection obtained.
Such as, in there is the smart mobile phone touching display screen, when user's icon to touching screen display
Carry out moving right operation time, the finger of user touches display screen, and moves right on screen, this
Time, sensor built-in in smart mobile phone can detect user with predetermined time interval (such as 1 millisecond)
The finger mobile operation to icon, thus sequentially obtain the position data of multiple touch location point.
Such as, generally with the upper left corner of mobile phone as initial point, right direction is the positive direction of X-axis, is downwards
The positive direction of Y-axis, thus obtain the position data (X1, Y1) of a series of touch location point, (X2,
Y1)......(XN, Y1), (XN+1, Y1) ....
Step S102: according to the mobile operation to the object shown on described touch sensitive display unit, sequentially
Calculate each corresponding multiple predicted position points with the plurality of touch location point, and each in acquisition
Described object is shown at predicted position point.
Conventionally, as only just process and display object after obtaining touch location point,
And this process and display process need certain time, the finger of user is therefore caused to move to the next one, very
To being just to show object at current location point after several touch location point, that so gives user feels it is electric
Subset bradykinesia, and picture is displayed without following closely the movement of hands, say, that so-called not with hands,
This cause user to feel picture is the most smooth, the situation of frame-skipping the most even occurs.
And in display packing according to embodiments of the present invention, unlike the prior art, in step S102
In premeasuring added to obtain corresponding predicted position point for each touch location point, and at this
Predicted position point display object.As in figure 2 it is shown, this predicted position point is than this touch location point in advance.Also
That is, according in the display packing of the present embodiment, the mobile operation of look-ahead user, and base
Predict the outcome in this, the direction that user moves shows object in advance, so that the finger of user exists
After contact display screen starts to slide, picture immediately begins to slide, and during finger slides, uses
Family can feel that picture slides with finger all the time.
Specifically, display packing according to embodiments of the present invention obtains the plurality of prediction by following steps
Location point: determine the direction of mobile operation；Determine a premeasuring；And in a certain direction, to often
The position data of individual touch location point adds this premeasuring, thus obtains the plurality of predicted position point.
Such as, in display packing according to a first embodiment of the present invention, position can be touched by first
The position data putting a little He the second touch location point determines the direction of mobile operation.It is to say, in vacation
If in the case of the one-dimensional mobile operation that user is carried out, touched by first touch location point and second
The position data touching location point is assured that the direction that user's finger moves.
Such as, as X2-X1 ＞ 0, determine that user's finger moves right；
As X2-X1 ＜ 0, determine that user's finger is moved to the left；
As Y2-Y1 ＞ 0, determine that user's finger moves down；
As Y2-Y1 ＜ 0, determine that user's finger moves up.
Alternately, it is also possible to by n-th touch location point and the position of the N+1 touch location point
Data determine the direction of mobile operation, and wherein N is positive integer.That is, say, that assuming
In the case of the mobile operation of the two dimension that user is carried out, by later touch location point and previous touch
The position data of location point is assured that the direction that user's finger currently moves.
Then, determine premeasuring by various modes, and in a certain direction, to each touch position
Put position data a little and add this premeasuring, thus obtain the plurality of predicted position point.
Such as, described premeasuring can be a fixed value.It is to say, the side moved at user's finger
Shift to an earlier date certain distance the most regularly to show, so so that the picture of display and the finger of user
More follow closely.
Certainly, add a premeasuring regularly and may not make the reality of picture position and user
The coupling completely of operating position, therefore, the most described premeasuring determines according to formula (1):
βN=XN-XN-1……(1)
Wherein, βNIt is intended to add to the premeasuring of the position data of n-th touch location point, XN-1It is
The position data of N-1 touch location point, XNIt it is the position data of n-th touch location point.
Touch it is to say, the premeasuring of the position data of n-th touch location point to be added to is n-th
Touch the position data of location point and the difference of the position data of the N-1 touch location point, as such, it is possible to root
Premeasuring is dynamically added according to mobile operation before, so that picture position and the reality of user
Operating position is more nearly.
It is more preferably that described premeasuring determines according to formula (2) further:
βN=αN*(XN-XN-1)+(1-αN)*(XN+XN-2-2*XN-1)……(2)
Wherein, αNIt is the feedback modifiers factor of n-th touch location point, and
αN=(XN-2*(XN-1-XN-2)-XN-3)/(XN-2-XN-3)。
It is to say, in formula (2), introduce feedback modifiers factor-alpha, so that this premeasuring
Mate the practical operation of user more accurately.And this feedback modifiers factor-alpha can be before calculating every time
It is modified.
Specifically, because XN+1'=XN+βN, so knowable to formula (2)
XN+1'=XN+αN*(XN-XN-1)+(1-αN)*(XN+XN-2-2XN-1)
Revise α by the position data of actually detected point being brought in formula (2), can obtain following
XN+1=XN+αN+1*(XN-XN-1)+(1-αN+1)*(XN+XN-2-2*XN-1)
Thus have
XN+1-2*(XN-XN-1)-XN-2=αN+1*(XN-1-XN-2)
Thus obtain
αN+1=(XN+1-2*(XN-XN-1)-XN-2)/(XN-1-XN-2)
It is to say, αNAs the parameter of a real-time reaction user action, and in epicycle computing formula
Each reality coordinate points will determine next round α N+1。
Preferably, described premeasuring determines according to formula (3) further:
βN=e* αN*(XN-XN-1)+(1-αN)*(XN+XN-2-2*XN-1)……(6)
Wherein, e is empirical, its processing delay time representing electronic equipment and the premeasuring of interpolation
Correction ratio.1 can be taken under normal circumstances, but can be able to have not according to concrete electronic equipment
With value, can adjust by carrying out testing.
In view of user's velocity variations in touch operation, method according to a first embodiment of the present invention is also
Can be by obtaining each speed data of multiple touch location points, and according to each touch location point
Position data, speed data and described predetermined time interval etc. determine premeasuring.
Specifically, described premeasuring determines according to formula (4):
βN=VN*TN……(4)
Wherein, βNIt is intended to add to the premeasuring of the position data of n-th touch location point, VNBe
Mobile speed of operation at n-th position detection point, and TNIt it is described predetermined time interval.
It is to say, each predicted position point is directly added into a distance moved last time, it is with current
Speed is directly related, the most just have expressed the operation of user.
In view of detection and the process time delay of electronic equipment, and the display distance thus caused is poor,
Preferably, above-mentioned formula (4) is modified, thus described premeasuring is according to below equation (5)
Determine:
βN=(αN*VN*TN)+r……(5)
Wherein, αN=(XN-XN-1)/(VN-2*TN-2), r=X 'N-XN, XN-1It is N-1
The position data of individual touch location point, XNIt is the position data of n-th touch location point, X 'NIt it is n-th
The position data of predicted position point.
Method according to a first embodiment of the present invention, also includes determining described premeasuring so that n-th is pre-
Survey the distance between location point and the N+1 touch location point less than n-th touch location point and N+1
Distance between individual touch location point.It is to say, determine described premeasuring so that in n-hour,
Obtain the position X of touch location pointN, and calculate predicted position point XN+1’；The N+1 moment, in advance
Survey location point XN+1' place's display object, and obtain the position X of touch location pointN+1' wherein, it was predicted that position
Put an XN+1' and the position X of touch location pointN+1Between distance less than the position X of touch location pointNWith
The position X of touch location pointN+1Between distance.It is to say, side according to a first embodiment of the present invention
Method, in the N+1 moment, calculated predicted position point XN+1' and the touch location point X of realityN+1
" approximate " coincidence.
Additionally, in practical operation, the detection of sensor and the transmission of data are likely to occur mistake, this
Time will produce abnormity point.To this end, method according to a first embodiment of the present invention also includes: when n-th is pre-
When distance between survey location point and n-th touch location point exceedes predetermined threshold, determine this touch location
Point is out-of-the way position point, and filters this touch location point.
Specifically, X is worked asNDuring for abnormal report point, TN-TN-1Or XN-XN-1Far above meansigma methods, thus
Cause XN+1Also far beyond X 'N+1.We can do special handling according to this phenomenon to extremely reporting to put:
Such as, TN-TN-1The loss that meansigma methods means to report recently a little, T can be far aboveN-TN-1≈3(TN-TN-1)
Mean to have two report points to lose, reduce these points lost by historical data, reset α and calculate
X’N+2。
Additionally, the situation of a kind of abnormity point is when the operation of user becomes deceleration regime from acceleration mode
Time, due to XN+1Much larger than X 'N+1, the α that calculatesN+1More than 1, thus future position X ' can be causedN+2
The state that maintenance accelerates；But, actual physics report point has transferred deceleration to, the α so calculatedN+2Transfer negative value to, and then cause future position X 'N+3＜ X 'N+2.Our this abnormal phenomena is called future position
Inversely.Mainly, image reverse rolling may cause flating in reverse negative effect.It is thus desirable to
By X 'N+3These points filter.
