Below in conjunction with accompanying drawing, describe the technical scheme that each embodiment of the application provides in detail.
Embodiment 1
The embodiment of the present application provides the method for drafting of a kind of interface element, is used for solving in prior art interface The lag issues occurred when element moves.The method implement schematic flow sheet as it is shown in figure 1, Mainly comprise the steps:
Step 11, obtains the information characterizing the first interface element movement tendency;
Wherein, the first interface element, for existing in two interface elements of location tracking relation, comparatively speaking The interface element first moved.
In one embodiment, obtain the information characterizing the first interface element movement tendency, including: obtain At least two location parameter of the first interface element, and the first interface element is positioned at said two location parameter The moment during position represented respectively;According to described at least two location parameter, determine the first interface element Moving direction;According to described at least two location parameter, and the first interface element is positioned at said two position In moment during the position that parameter represents respectively, determine the translational speed of the first interface element.
Such as, if assuming, the first interface element started to be moved from the T1 moment, and in the T1 moment, first The location parameter of interface element is (0,11), the T2 moment after 5s, the position ginseng of the first interface element Number is (0,20), thus according to the two location parameter, it may be determined that go out the motion side of the first interface element To for vertically mobile (as along vertical coordinate axle Y-axis).
For example, it is assumed that sample according to the location parameter of the sample frequency focusing of 10ms, get Jiao The point location parameter in the t1 moment is (0,10), and the focus location parameter in the t2 moment is (0,20), Time interval between t1 moment and t2 moment is 10ms, then the movement velocity that can calculate focus is (20-10)/10;Or, when the first interface element is according to the default speed uniform motion of default, The motion velocity information of the first interface element can obtain from system set-up information.
In the embodiment of the present application, location parameter, refer to any information that can represent interface element present position, This information is such as coordinate figure etc..
In the embodiment of the present application, the mode obtaining the information characterizing the first interface element movement tendency is the most permissible Including following two:
Mode one: according to the default location parameter sampling period, obtains and characterizes the first interface element movement tendency Information.
Such as, as a example by the first interface element is as focus, if the location parameter sampling period 30ms preset, Then system will obtain the focus now coordinate figure of present position in screen coordinate system automatically every 30ms, makees It is the location parameter of the first interface element, and according to the location parameter of the first interface element, obtains sign first The information of interface element movement tendency.Wherein, in order to obtain the direction of motion information of the first interface element, adopt The location parameter of the first interface element that sample obtains at least needs two.
Mode two: after receiving the first interface element change in location triggering command, obtains and characterizes the first Interface Element The information of element movement tendency.
Such as, as a example by the first interface element is for digital TV screen focus, it is assumed that user is defeated by remote controller Enter focal position and adjusted instruction, then, at this DTV after receiving this instruction, focus can have been obtained and work as Front location parameter in screen coordinate system;Further, according to the default location parameter sampling period, obtain Take focus location parameter during being moved;And by each position parameter got, obtain focus Movement tendency information.
The mode of the movement tendency information obtaining focus according to location parameter in mode one and mode two can be joined According to above, here is omitted.
In one embodiment, in order to guarantee at set time intervals location parameter to be adopted Sample, the embodiment of the present application provides the mode of a kind of timing sampling.Which specifically includes:
According to the sampling period, system timer is set, whenever the timing time of system timer arrives according to adopting During the sampling instant that the sample cycle is determined, the first interface element location parameter is sampled.For example, it is assumed that Need every 30ms to obtain the location parameter of a secondary focal point, then the time arranging system timer is 30ms, enters And by by the timing time of system timer, sample every the location parameter of 30ms focusing.
Step 12, according to the information characterizing the first interface element movement tendency, it was predicted that the first interface element will The target location moved to;
In one embodiment, if the information of the first interface element movement tendency includes the first interface element Translational speed and moving direction, then the specific implementation of step 12 may include that according to display interface Drafting cycle, described translational speed and moving direction, it was predicted that the target that the first interface element will move to Position.
In the drafting cycle of above-mentioned display interface, i.e. interface (is such as being comprised the first interface element and the second boundary The interface of surface element) drafting cycle of display interface of being followed when drawing, the drafting of this display interface Cycle can be 30ms, 40ms, etc..When the drafting cycle of display interface is 30ms, can be every 30ms carries out the drafting at a frame interface.In the embodiment of the present application, this display interface is drawn the tool in cycle Body size does not limits.
In the embodiment of the present application, if assuming to carry out pre-in the target location that the first interface element will be moved to During survey, the first interface element is currently in drawn nth frame interface, and, the drafting of display interface Cycle is 30ms, then, in step 12, it is possible to according to the drafting cycle 30ms of this display interface, Information with sign the first interface element movement tendency got, it was predicted that the first interface element is at N+1 The target location that the interfaces such as frame or N+2 frame will move to time drawn.
Such as, if the central point of the first interface element be currently in drawn nth frame interface (10, 0) this position, the drafting cycle of display interface is 30ms, characterizes the movement tendency of the first interface element Information includes when the direction of motion is the most to the right and movement velocity is 5/30ms, then, permissible Dope the first interface element when N+1 frame interface is drawn, be in (15,0) this target location. Wherein, in above-mentioned (10,0) 10, in movement velocity expression formula 5/30ms 5, and above-mentioned (15, 0) 15 in, can be all the unit length in interface coordinate system.
It should be noted that in one embodiment, in order to according to the first interface element motion got The target location that information prediction first interface element of trend will move to, the embodiment of the present application provides one Estimation algorithm, this algorithm can be completed by the first interface element displacement estimator.
It should be noted that this estimator is in addition to having may be used for step 12, it is also possible to be used for Step 11.Such as, this estimator can calculate the according to the location parameter of the first interface element got The translational speed of one interface element, and determine the moving direction of the first interface element;And then according to instantaneous speed Degree, moving direction, it was predicted that the target location that the first interface element will move to.
As a example by the first interface element is as focus, assume to set up if following:
1, this focus shows on the interface of intelligent television;
2, this intelligent television is with the drafting cycle of 30ms, draws each frame display interface;
3, focus X-axis in the horizontal direction moves;
4, in the T0 moment, intelligent television receives focus movement instruction, i.e. focus started to move in the T0 moment Dynamic;
5, the focus location parameter in the T0 moment is (x0, y1);
6, according to the sampling period of default, the location parameter of focusing is sampled.Wherein, this is adopted The sample cycle is identical with the drafting cycle of display interface, for 30ms.
So, to complete the step of above-mentioned calculating process as follows for this estimator:
One, as shown in Figure 1a, it is assumed that focus starts with movement in the T0 moment, then, this estimator is permissible Get the location parameter (x0, y1) of focus in the T0 moment, get the position ginseng of focus in the T1 moment Number (x1, y1);The location parameter (x2, y1) of focus is got in the T2 moment.
Wherein, T0 moment and T1 moment, the time interval between T1 and T2 is drafting cycle, i.e. 30ms.
Two, the location parameter (x0, y1) of the focus that this estimator got according to the T0 moment and the T1 moment The location parameter (x1, y1) of the focus got, calculates the horizontal coordinate before and after focus moves poor: TotalDistanceX=x1-x0.
Three, it is in the moment T1 of (x1, y1) according to totalDistanceX, focus, and focus is in The moment T0 of (x0, y1), the translational speed of calculating focus: FocusViewMovingVelocityX=totalDistanceX ÷ (T1-T0).
Four, according to translational speed and T2, the calculating focus displacement from T0 to T2: ExpectedDistanceX=focusViewMovingVelocityX × (T2-T0).I.e., it was predicted that focus is in sight The T2 that will arrive, moves how many distances relative to present position during T0.
Five, according to the location parameter (x0, y1) of T0 moment focus, the location parameter of T1 moment focus (x1, Y1), it may be determined that the information of the movement tendency going out focus is X-axis in the horizontal direction.
Six, according to the information of the movement tendency of focus determined and calculate ExpectedDistanceX, measurable go out the target location that will move in this moment of T2 of focus, i.e. Focus location parameter after X-axis moves in the horizontal direction is (x0+expectedDistanceX, y1).
Computing Principle based on above-mentioned estimator, such as, it is assumed that focus started to be moved in the t0 moment, its The location parameter in t0 moment is (0,9), if according to the default focal position parameter sampling cycle, getting The focus location parameter in the t1 moment is (0,12), then may determine that the moving direction of focus is for along Vertical Square Move to Y direction;Can calculate at the location parameter in t0 moment and t1 moment according to focus simultaneously Focus t0 to t1 during this period of time in displacement be: (12-9)=3, time interval is: t1-t0=30ms. Then according to displacement and time interval, the translational speed of focus can be calculated: 3 ÷ 30=0.1.Assume to need Focus to be predicted arrived in the t2 moment sampling period 30ms of systemic presupposition (time interval of t2 Yu t1 be) The parameter of target location, then according to moving direction and the translational speed of focus of focus, can calculate and discharge of the coke The distance that point moved in the t2 moment is: instantaneous velocity × (t2-t1)=0.1 × 30=3;Then focus is when t2 The location parameter being carved into the target location reached is (0,15).
Step 13, draws second contact surface element according to target location.
In the embodiment of the present application, draw the moment of second contact surface element according to described target location, there may be Following three kinds of situations:
Situation 1: when the first interface element moves to target location, draws second contact surface according to target location Element.
For example, it is assumed that the first interface element arrives target in the T1 moment (particular moment the most described) Position, then in the T1 moment, draw second contact surface element according to target location.
For example, if assume: 1, according to the drafting cycle of 30ms, draw comprise the first interface element and The display interface of second contact surface element;2, that step 11 gets, for characterizing the first interface by performing The information of element movement tendency is: the first interface element is respectively at the first frame display interface drawn and the second frame Location parameter in display interface;3, the first interface element is currently at the second frame display interface.So, According to described target location draw second contact surface element moment, can be drafting the 3rd frame display interface time Carve, be i.e. later than the moment of the drafting moment 30ms of the second frame display interface.
Situation 2: when before the first interface element moves to target location, draws according to target location Second contact surface element.
It is assumed that the first interface element starts in the T0 moment mobile, arrive target location in the T1 moment, then may be used With after the T0 moment, (particular moment the most described) sometime before the T1 moment, according to Second contact surface element is drawn in target location.
Situation 3: (this moment in the setting duration after the moment that the first interface element moves to target location After any instant set in duration, all can be considered as particular moment described above), according to target position Put drafting second contact surface element.Wherein, this setting duration, should meet: user will not be made visually, The moment of drawing experiencing second contact surface element substantially lags behind the drafting moment of the first interface element.
It is assumed that the first interface element arrives target location in the T1 moment, the most the latest in the T1+ Δ T moment, paint Second contact surface element processed.Wherein, [0, Δ T] is above-mentioned setting duration.
In the embodiment of the present application, draw second contact surface element according to the target location determined, specifically can wrap Include following two implementation:
Implementation 1: according to target location and the distance threshold of setting, determines the first drafting position;And Described particular moment, draw second contact surface element according to target location.
Specifically, the position that current with second contact surface element in target location location parameter represents (is called for short afterwards Element current location) between distance less than set distance threshold time, element current location can be determined Position is drawn for second contact surface element;Thus in described particular moment, element current location is painted as first Position processed, and second contact surface element is drawn in this position.Especially, target location is likely current with element Position overlaps, and the most above-mentioned distance is 0.
When distance between target location and element current location is not less than the distance threshold set, can be by Target location is defined as second contact surface element and draws position;Thus in particular moment, draw the in target location Second interface element.
In one embodiment, for the distance threshold according to target location and setting, second contact surface is determined Element draws position, and the embodiment of the present application provides a kind of estimation algorithm, and this algorithm can be by second contact surface element Displacement estimator completes, and concrete algorithm is as follows:
1、totalDistanceX!=0&&ViewMovingDistanceX==0;
2, (wherein 0.45 is the most adjustable to expectedDistanceX > 0.45*totalDistanceX Parameter), and focusViewAccmulateDistanceX < expectedDistanceX).
Wherein the specific algorithm of parameters is described above, and here is omitted.
Implementation 2: according to target location, it is judged that the first interface element moves to institute at the first interface element State the moment of target location, if be moved to outside the viewing area that second contact surface element currently occupies;According to Judged result, determines that second contact surface element draws position;And move to described target position at the first interface element In the moment put, draw position at second contact surface element and draw second contact surface element.
Specifically, it is that the first interface element moves to described target location at the first interface element when judged result Moment be moved to outside the viewing area that second contact surface element currently occupies, then target location is defined as Second interface element draws position;When judged result is described in the first interface element moves at the first interface element The moment of target location does not move to outside the viewing area that second contact surface element currently occupies, then by the second boundary The position, viewing area that surface element currently occupies, is defined as second contact surface element and draws position.
Such as, as a example by DTV, it is assumed that the first interface element is focus, second contact surface element is focus Frame.Assuming under original state, on screen as shown in Figure 1 b, focus and focus frame are all in identical position Putting, wherein, the viewing area that focus frame currently occupies is the gray area in figure.When user passes through remote controller Focusing is moved so that after focus moves to position as illustrated in figure 1 c, due to the position of focus Do not move to, outside the gray area shown in Fig. 1 c, the most now gray area position is defined as second Interface element draws position.
In one embodiment, the moment of described target location is moved at the first interface element to the second boundary The mode that surface element carries out drawing may include that according to the first interface element move to described target location time Carve the feature being in the 3rd interface element that second contact surface element draws position, draw second contact surface element.
Specifically, draw second contact surface element according to the feature of the 3rd interface element, may refer to according to Make second contact surface element possess the mode of this feature, draw second contact surface element;May also mean that according to making Second interface element does not possess the mode of this feature, draws second contact surface element.
Such as, as a example by the TV play poster that digital television switching is selected, if focus is from TV play poster A (wherein TV play poster A is square) (wherein TV play poster B is for long to move to TV play poster B Square, and this TV play poster B position is the target location determined), then the mesh arrived in focus When cursor position draws focus frame, by the shape facility according to poster B, focus frame is depicted as rectangle.
It should be noted that the feature of the 3rd interface element includes: shape, color, size, animation effect Deng.
Said method can be completed by the drafting assembly of a kind of interface element as shown in Figure 1 d, this Interface Element Element drafting assembly specifically include with lower module: movement tendency data obtaining module, target prodiction module, Drafting module, system timer and core calculations module (include the first interface element displacement estimator With second contact surface element displacement estimator).
The function of above-mentioned each module introduced below.
Above-mentioned steps 11 can be completed by movement tendency data obtaining module.
The target location that the first interface element described in step 12 will move to, can be by target location Parameter that prediction module calculates according to the first interface element displacement estimator and predict and draw.This is first years old The functional realiey mode of interface element displacement estimator refers to above, and here is omitted.
System timer can set fixed time interval as the sampling period, so that location parameter obtains The time interval that delivery block can set according to system timer, is carried out the location parameter of the first interface element Sampling.
Second contact surface element displacement estimator, is used for according to target location and the distance threshold of setting, really Determine second contact surface element and draw position.The functional realiey mode of this second contact surface element displacement estimator is detailed Seing above, here is omitted.
Drafting module, can will move to target location, to the first boundary according to the first interface element of prediction Surface element is drawn;And draw position according to the second contact surface element determined, second contact surface element is carried out Draw.
The said method provided by the embodiment of the present application 1, the method is by transporting the first interface element The information of dynamic trend calculates, and can dope the target location that the first interface element will move to, enter And second contact surface element can be drawn in particular moment according to target location, reduce second contact surface element and move Dynamic hysteresis quality, thus avoid because user's repeats mobile operation, decrease taking of system resource, Improve the operational efficiency of system.
It should be noted that the executive agent of each step of the provided method of embodiment 1 may each be same and sets Standby, or, the method also by distinct device as executive agent.Such as, the holding of step 11 and step 12 Row main body can be the first interface element control, and the executive agent of step 13 can be second contact surface element control Part;The most such as, the executive agent of step 11 can be the first interface element control, step 12 and step 13 Executive agent can be second contact surface element control;For another example, step 11~the executive agent of step 13 It can be all second contact surface element control;Etc..
