Specific embodiment
Further to illustrate that the present invention is the technological means and effect that the predetermined goal of the invention of realization is taken, below in conjunction withAttached drawing and preferred embodiment, to the specific embodiment party according to interface focus control method for movement proposed by the present invention and control deviceFormula, structure, feature and its effect are described in detail as after.
Fig. 1 is the flow chart for the interface focus control method for movement that first embodiment provides, as shown in Figure 1, the interface is burntPoint control method for movement includes：
Step S110, initial position and the motion track of contact are recorded；
Step S120, the displacement distance of contact is obtained；
Step S130, the displacement distance and predetermined value are compared：
Step S140, the trajectory angle of contact is obtained；
Step S150, the course bearing of focus is obtained according to trajectory angle；
Step S160, focus mobile at least lattice on the course bearing are made；And
Step S170, current location is set as initial position.
Specifically, as shown in Fig. 2, in step S110, the coordinate (Xa, Ya) of record contact initial position A points, while withThe track of the moving recording contact of contact, it will be understood that can only record the point that contact is passed through for the motion track of contact,When the point of sampling is enough, the line of each point just meets with actual track.In step S120, it is assumed that contact is currently moved toD points (Xd, Yd), between starting point A and current point D, there are two tracing point B, C, coordinate be respectively (Xb, Yb) and (Xc,Yc).Then from initial position A to current location D, the displacement distance D=D of contactAB+DBC+DCD, wherein DABRepresent A points and B points itBetween distance, DAB=((Xb-Xa)2+(Yb-Ya)2)1/2, other distances and so on.It is i.e. available from A points via the above processTo the displacement distance of D point points.
In step s 130, the size of the displacement distance of comparison touch points and predetermined value, above-mentioned predetermined value are, for example, 50Pixel carries out angle judgement after contact is moved more than 50 pixels, that is, performs step S140.It can be with when obtaining trajectory angleUsing starting point A and current location D.As shown in Fig. 2, tan θ=(Yd-Ya)/(Xd-Xa), then correspondingly, trajectory angle θ=atan((Yd-Ya)/(Xd-Xa)).Furthermore, it is to be understood that it is not limited in when obtaining trajectory angle using starting point A.For example,It can also recall since the D of current location along tracing point to starting point direction up to finding the shifting between the point and current location DDynamic distance is more than the point of predetermined value.Predetermined value herein is, for example, 100 pixels.For example, in 4 points shown in Fig. 2, Ke NengcongD points start to recall, and it is more than 100 pixels to determine the displacement distance between BD, it is determined that B points are starting when obtaining trajectory anglePoint, angle are θ=atan ((Yd-Yb)/(Xd-Xb)).It is appreciated that in example provided above, range estimation is carried outIt is small to be spaced the distance (100 pixel) that (50 pixel) is recalled than direction determining when finding starting point, it is thus possible to there is scenario described below,Even if dateing back starting point, the point that displacement distance is more than 100 pixels is not found yet, at this point, can be directly using starting point as calculatingThe starting point of angle.
In step S150, the course bearing of focus is obtained according to trajectory angle, such as 45 ° of -45 ° of ＜ θ ＜, determineFor course bearing for the right, it is upward that course bearing is determined as 135 ° of 45 ° of ＜ θ ＜, is determined as 135 ° of θ ＞ and ＜ -135 ° of θCourse bearing determines course bearing for the right for the left as ＜ -45 ° of -135 ° of ＜ θ.It, will according to the scope of above-mentioned angular rangeThe movement of any direction is converted into one in the four direction of upper and lower, left and right.It will be understood, however, that the model of above-mentioned angular rangeEnclose it is merely illustrative, for example, it is also possible to be that course bearing is determined as 30 ° of -30 ° of ＜ θ ＜ as to the right, and as 120 ° of 60 ° of ＜ θ ＜Course bearing is determined as to the right, and course bearing is determined as upper right as 60 ° of 30 ° of ＜ θ ＜, is i.e. focus while to the right and to moving upIt is dynamic.Other directions can and so on.
After determining course bearing, in step S160, you can focus is made to move an at least lattice.Focus is made to move an at least latticeIt is at least next interface element that focus is instigated to be moved in same a line or same row.In addition, if current focus isBoundary positioned at interface can be set for operating according to different.For example, current focus is located at the right margin at interfacePlace, definite course bearing are that the right, can be operated at this time without any focus, can be moved in one's own profession firstInterface element can also be first interface element being moved in next line.The border in other directions can and so on.
The movement of focus can be accomplished in several ways.For example, focus interface element can around it display bezelTo be distinguished with other interface elements, at this point, then this frame can be with gradual movement to next interface element.Focus interfaceElement can also be to be distinguished using the background of gradual change with other interface elements, at this point it is possible to current focus interface element backgroundCarry out processing of fading out, and the background of the asymptotic next interface element of display.It is appreciated that the movement of focus is not limited to more than instituteThe two ways enumerated, the technology of arbitrary moving focal point can be applied in the present embodiment.
In step S170, when complete focus movement after, you can current location is redefined as starting point, again intoThe process of row step S120 to step S160.In this way, moving focal point can be continued in the case of contact is not unclamped.
In above-mentioned interface focus control method, by tracking the motion track of contact, when contact, displacement distance is more thanOr focus is automatically moved during equal to predetermined value, that is, the interface element around current focus is selected, compared to traditional direct touch-controlIt chooses, can solve the problems, such as that interface element is too small and be not easy to choose.Whole process can realize that operation is simple by lasting slipJust.
Refering to Fig. 3, second embodiment provides a kind of interface focus control method for movement, is moved with the focus of first embodimentFlowing control method is similar, the difference is that, further comprise：
Step S210, the last mobile direction of the course bearing obtained in comparison step S150 and the focus whether phaseTogether；And
Step S220, when the last mobile direction of course bearing and focus is identical the movement of focus point carry out at accelerationReason.
It is appreciated that in order to carry out step S210, it is necessary to which its moving direction of moving focal point also respective record is for rear every timeIt is continuous to compare.It is appreciated that during each moving focal point, course bearing is its moving direction.In step S220, course bearing withThe last mobile direction of focus is identical, illustrates that focus needs persistently to move in the same direction.Acceleration processing for example refers toMake one increment of lattice number for giving focus movement.For example, in a certain direction, the only mobile lattice of the first secondary focal point, and secondExcept moving one especially, also with an increment, when this increment is 1, then two lattice are moved second.This increment may be, for example, 0.5*N,Wherein N is the number moved in the same direction.By upper formula, then mobile 1+0.5*2=2 lattice are needed when second is mobile, the 3rdMobile 1+0.5*3=2.5 lattice are needed when secondary mobile.For fractional part, can rounding downwards or round up handled.When using downward rounding mode, when mobile 2 lattice are needed when mobile for the third time, and being handled using the mode of rounding up, theIt is mobile three times to need mobile 3 lattice.It can be seen from the above, when the number that focus continuously moves in the same direction is more, currentTranslational speed is faster.
