Embodiment
The embodiment of the invention moves the accuracy of control for cursor on the raising touch screen mobile communication terminal, a kind of cursor control technology that moves according to control volume sliding speed control cursor is provided, the length of displacement and the speed of sliding speed are complementary, concrete grammar comprises the steps: as shown in Figure 2
Step S201, acquisition control body drag sliding trace and the sliding time of cursor when moving on touch-screen;
Step S202, determine the sliding speed of control volume according to sliding trace and sliding time;
Step S203, determine the displacement of cursor on touch-screen according to sliding speed;
General, the displacement of the more little then cursor of control volume sliding speed is short more, and the displacement of the big more then cursor of control volume sliding speed is long more, and when sliding speed was lower than the threshold value of setting, cursor did not move.Certainly, also entertainment mode can be set, the displacement of controlling cursor when the control volume sliding speed is big more on the contrary is short more, and the control volume sliding speed more hour displacement of control cursor is long more.
Step S204, move preceding place label according to displacement and cursor, the control cursor moves on touch-screen.
Control volume drags the sliding trace of cursor when moving on touch-screen can be straight line, it also can be a curve, even can also be a broken line, the technology of acquisition control body sliding trace and sliding time is well known to those skilled in the art, and is not describing in detail here.
After obtaining sliding trace and sliding time, in step S202, can have two kinds of methods to determine the sliding speed of control volume according to sliding trace and sliding time, consult sliding trace shown in Figure 3, definite method of first kind of sliding speed V as shown in Equation 1:
V＝L/T..............(1)
Wherein, L is the total length of sliding trace, and T is a sliding time;
Definite method of second kind of sliding speed V is as shown in Equation 2:
V＝D/T..............(2)
Wherein, D is the slip starting point of sliding trace and the air line distance between the terminal point, and T is a sliding time;
Certainly those skilled in the art can adopt other method, and for example cursor displacement S multiply by behind the certain proportion divided by T, calculates V etc., enumerates no longer one by one here.
As shown in table 1 below, in the embodiment of the invention, can rule of thumb be worth, divide different velocity ranges in advance, and be the corresponding cursor amount of movement of setting of each velocity range:
Table 1.
| Progression | Velocity range | Cursor amount of movement S |
| The first order | ?V≤V1 | ?S1 |
| The second level | ?V1＜V≤V2 | ?S2 |
| The third level | ?V2＜V≤V3 | ?S3 |
| ??...... | ?...... | ?...... |
| The n level | ?Vm＜V≤Vn | ?Sn |
Wherein: the unit of S, L and D is identical, and progression n can determine according to label number on the touch-screen, for example is set at 3 grades during 3 labels.The cursor amount of movement S1 of first order correspondence can be set at 0, promptly when the sliding speed of control volume during smaller or equal to the threshold value V1 that sets, and moving cursor not.In fact corresponding cursor amount of movement Sn at the highest level is subjected to the restriction of touch-screen size, when on the touch-screen Width when mobile, Sn is for the touch-screen width deducts the width of a label, that is to say that the longest displacement of cursor is that label from the edge of touch-screen moves on the label on another side edge.Cursor has same characteristic, no longer repeat specification when the touch-screen short transverse moves.
According to different touch-screen actual mode of operation, cursor can only move at Width, also can only move on short transverse, perhaps both can move at Width, also can move on short transverse.Because sliding trace shown in Figure 3 can not be consistent with moving direction, can determine according to the actual speed of control volume when therefore determining cursor displacement, also can determine according to the component of actual speed on different moving directions of control volume.
With cursor definite method of displacement when the touch-screen Width moves is example, can comprise three kinds, referring to shown in Figure 4, the Width of supposing touch-screen is X, when the starting point direction to terminal of sliding trace was considered as the direction of sliding speed V, first method specifically comprised:
Determine the first speed component Vx of sliding speed V on touch-screen Width X, according to being the corresponding amount of setting of moving horizontally of friction speed scope, for example S can see the amount of moving horizontally that the corresponding speed scope is set as in the table 1, with the amount of moving horizontally of the first speed component Vx place velocity range correspondence, be defined as controlling cursor and on the touch-screen Width, move horizontally distance when mobile.
Second method is specially: directly determine to move horizontally distance according to sliding speed V, be about to the amount of moving horizontally of sliding speed V place velocity range correspondence, be defined as cursor and move horizontally distance on the touch-screen Width.
The third method is identical with first method essence, referring to shown in Figure 4, be specially: the first distance component Dx of air line distance D between sliding trace starting point and the terminal point on the touch-screen Width is defined as the horizontal slip speed component divided by the merchant of sliding time T, and according to being the corresponding amount of setting of moving horizontally of friction speed scope, with the amount of moving horizontally of horizontal slip speed component place velocity range correspondence, be defined as cursor and on the touch-screen Width, move horizontally distance.In fact, the result of calculation of horizontal slip speed component and speed component is identical.
Equally, when cursor only when the touch-screen short transverse moves, determine that according to sliding speed the method for the displacement of cursor on touch-screen also can comprise corresponding three kinds, still referring to Fig. 4:
First kind: determine the second speed component Vy of sliding speed on touch-screen short transverse Y, according to being the corresponding vertical moving amount of setting of friction speed scope, for example S can see the vertical moving amount that the corresponding speed scope is set as in the table 1, with the vertical moving amount of second speed component Vy place velocity range correspondence, be defined as controlling cursor displacement when mobile on the touch-screen short transverse;
Second kind:,, be defined as the vertical moving distance of cursor on the touch-screen short transverse with the vertical moving amount of sliding speed V place velocity range correspondence according to being the corresponding amount of movement of setting of friction speed scope.
The third: the second distance component Dy of air line distance D between sliding trace starting point and the terminal point on touch-screen short transverse Y is defined as vertical sliding speed component divided by the merchant of sliding time; And,, be defined as the vertical moving distance of cursor on the touch-screen short transverse with the vertical moving amount of vertical sliding speed component place velocity range correspondence according to being the corresponding vertical moving amount of setting of friction speed scope.
Preferable, in table 1, moving horizontally distance and the amount of moving horizontally is unit with the label number all, and promptly corresponding friction speed scope is set cursor and begun the number of labels that move from current label, is used for instructs cursor and begins the mobile reference label quantity of needs from moving preceding place label.Then still consult shown in Figure 4, when cursor when the touch-screen Width moves, move preceding place label according to displacement and cursor, the control cursor moves on touch-screen and specifically comprises:
Determine motion track starting point the horizontal projection direction of direction on the touch-screen Width, i.e. Vx direction to terminal;
Determine on the touch-screen that cursor moves the total label number of preceding place label along Vx direction one side;
When total label number when moving horizontally the reference label quantity of distance indication, cursor is moved along the Vx direction, move back place label and move between the label of preceding place and comprise that reference label quantity subtracts 1 label, otherwise cursor is moved into place on the label at the edge of touch-screen along the Vx direction.
That is to say, if total label number greater than the reference label quantity that moves horizontally the distance indication, then moves on on the target labels cursor is actual, target labels and move before label between the number of tags of being separated by be: reference label quantity subtracts 1.If total label number is equal to or less than the reference label quantity that moves horizontally the distance indication, cursor can only be moved on the label at edge.
The mobile control principle of cursor on the touch-screen short transverse is identical, consults shown in Figure 4ly, is specially:
Determine motion track starting point the vertical projection direction of direction on the touch-screen short transverse, i.e. Vy to terminal;
Determine on the touch-screen that cursor moves the total label number of preceding place label along Vy direction one side;
When total label number greater than vertical moving apart from the indication reference label quantity the time, cursor is moved along the Vy direction, move back place label and move between the label of preceding place and comprise that reference label quantity subtracts 1 label, otherwise cursor is moved into place on the label at the edge of touch-screen along the vertical projection direction.
If the unit of displacement and amount of movement is identical with D or L, then the embodiment of the invention also provides a kind of cursor control method for movement, can the integral part of distance or vertical moving distance divided by a cursor width gained will be moved horizontally earlier, be defined as cursor and begin to need mobile reference label quantity, adopt above-mentioned principle to control then from moving preceding place label.
In the embodiment of the invention,, when promptly amount of movement is zero, can controls cursor and keep motionless at touch-screen if displacement is zero.Further, for reaching better animation effect, can make cursor along with control volume rocks according to translational speed to the cursor control that rebounds.Specifically comprise: when cursor when the touch-screen Width moves, cursor is moved along the horizontal projection direction retract again after first distance of setting and moves preceding place label; When cursor when the touch-screen short transverse moves, cursor is moved along the vertical projection direction retract again after first distance of setting and move preceding place label, the length of first distance is less than the width of a label, and determine that according to reference label quantity first distance is followed reference label quantity and reduced and shorten.
Same principle, when total label number is equal to or less than reference label quantity, for obtaining better animation effect, when cursor when the touch-screen Width moves, cursor is moved into place after on the label at the edge of touch-screen along the horizontal projection direction, further cursor is moved along the horizontal projection direction on the label of retracting the edge of touch-screen after first distance of setting again; When cursor when the touch-screen short transverse moves, cursor is moved into place after on the label at the edge of touch-screen along the vertical projection direction, further cursor is moved along the horizontal projection direction on the label of retracting the edge of touch-screen after first distance of setting again.Like this, after cursor arrives edge label, can also rebound touching on the screen-wall.
