Embodiment
Below in conjunction with Figure of description embodiment of the present invention is described.This instructions mainly with the application of the present invention in instant communication service as most preferred embodiment, certainly, also can be used for other Internet service systems such as webmail service system, network cooperating work service system in the practical application.
In a kind of method that embodiment of the present invention provides based on scroll control realization content choice, as shown in Figure 1, comprising:
The position and the time corresponding of thing clicked in step 11, record;
Particularly, said click thing can be finger or the writing pencil on the touch apparatus, also can be mousebutton; If in the windows system, will point usually or the click event of writing pencil is mapped as mouse click event: finger or writing pencil touch are pressed corresponding mousebutton and are pressed (MouseButtonDown); Finger or writing pencil touch mobile corresponding mouse and move (MouseMove); Finger or writing pencil touch are lifted corresponding mousebutton and are lifted (MouseButtonUp); Utilize corresponding preparatory incident PreviewMouseButtonDown, PreviewMouseMove and PreviewMouseButtonUp to receive mouse information intercepting and capturing incident before in scroll control; For example, in the preparatory incident of PreviewMouseButtonDown, create an initialization and click thing touch track record, and the position coordinates and the time of thing clicked in record; The position coordinates and corresponding time after thing moves at every turn clicked in record in the preparatory incident of PreviewMouseMove; Position when the record finger lifts in the preparatory incident of PreviewMouseButtonUp and corresponding time, and finish track record.
Further, at first, the setting-up time interval, the said time interval can be 1s, also can be 10 millimeters, confirms according to user operation habits or use experience; Then, every position and time corresponding of clicking thing of noting at a distance from the said time interval: specifically can set up two-dimentional rectangular coordinate system, note coordinate figure and the time corresponding of clicking thing.
Whether the linear velocity initial value that step 12, the position corresponding with the final time of said record, position when judgement is lifted according to said click thing obtain is 0, if then execution in step 13; If not, execution in step 14 then;
Position when lifting as if the click thing particularly, is (X
n, Y
n) the corresponding time is T
n, the final time of record is T
N-1Corresponding position is (X
N-1, Y
N-1), then the initial value of linear velocity be (| X
n-X
N-1|, | Y
n-Y
N-1|)/(T
n-T
N-1); If the linear velocity initial value is 0, then explain and selected the content that needs when the user lifts, and if the linear velocity initial value is not 0, then explanation also wants to continue to select other content when lifting, and promptly just can understand user's selection intention according to said linear velocity initial value.
Step 13, directly choose corresponding contents.
Step 14, obtaining corresponding displacement according to the initial value of said linear velocity, and according to said displacement adjustment scroll control, is 0 to choose corresponding contents up to said displacement.
Particularly, at first, preestablish acceleration; Said acceleration can be 1 (displacement/second), also can be 1 (displacement/millisecond), and confirm according to user operation habits or use experience: for example: horizontal ordinate directional ray speed initial value is 5mm/ms; No ordinate directional ray speed initial value; The setting acceleration is 1mm/ms, because the time is the unit interval so can ignore chronomere, then initial displacement is 5-1=4mm; Just adjust scroll bar rolling 4mm in the scroll control, this moment, linear velocity also was reduced to 4mm/ms; Continuing to obtain displacement is 4-1=3mm, continues scroll bar rolling 3mm in the adjustment scroll control, and this moment, linear velocity also was reduced to 3mm/ms; By that analogy, be reduced to 0mm/ms, then choose scroll bar through repeatedly moving the content on the position, back up to said displacement.
Said method has reached a kind of inertia effect; Promptly when user finger streaks on a control that has a scroll bar; Scroll bar not only will be followed user's finger and rolled, and when user's finger leaves and has certain initial velocity, can continue to roll and stop slowly.
Further, if the scroll bar in the scroll control arrives the border, be 0 o'clock then at said displacement, turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.For example: horizontal ordinate directional ray speed initial value is 5mm/ms; No ordinate directional ray speed initial value, the setting acceleration is 1mm/ms, because the time is the unit interval so can ignore chronomere; Then initial displacement is 5-1=4mm; Just adjust scroll bar rolling 4mm in the scroll control, but the only remaining 3mm of scroll bar horizontal ordinate corresponding contents can show at this moment, is reduced at 0 o'clock at said displacement so; Turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.The process on the scroll bar border in turning back to said scroll control can playing animation or picture.
Perhaps,
If when scroll bar arrives the border,, it is not 0 o'clock then at the said displacement that successively decreases gradually if the scroll bar in the said scroll control arrives the border; Show blank gradually; Be reduced at 0 o'clock at said displacement, turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.For example: ordinate directional ray speed initial value is 5mm/ms, no horizontal ordinate directional ray speed initial value, and the setting acceleration is 1mm/ms; Because the time is the unit interval so can ignore chronomere, then initial displacement is 5-1=4mm, just adjusts scroll bar rolling 4mm in the scroll control; But the only remaining 3mm of scroll bar horizontal ordinate corresponding contents this moment; The displacement that basis is successively decreased gradually after scroll bar arrives boundary position so shows blank gradually, is reduced to 0 o'clock up to said displacement; Turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.The process on the scroll bar border in turning back to said scroll control can playing animation or picture.Just reached a kind of elastic effect this moment, when promptly scroll bar arrives the border, if finger continues to drag to the border; Then content displacement is not directly proportional with finger displacement, but presents the pulling force effect of spring-like, and it is big more to be specially finger displacement; The resistance that receives when content moves is just more little, and the maximal value that has a content to move, and promptly no matter points and how far moves; The distance that content moves can only be infinitely near this maximal value, and can not meet or exceed this maximal value.
Particularly; The existing control that has scroll bar all is (like ListBox or the RichEditBox) that realizes rolling function through the basic control of ScrollViewer (roll events); As long as the rolling behavior of control ScrollViewer; The operation of clicking thing promptly may be used on the control of other tape spools; Usually all being HorzontalOffset (horizontal component) and the position that VerticalOffset (vertical component) attribute obtains HScrollBar and the vertical position of scroll bar through visit ScrollViewer, is example with the mobile of vertical component further, judges that the process on scroll bar arrival border can comprise:
double?oldVerticalOffset＝this._scrollViewer.VerticalOffset；
double?p＝oldVerticalOffset-y；
If p is less than 0, then scroll bar has arrived the boundary of starting position; If p is greater than scrollViewer.ScrollzbleHeight (being the maximum displacement of vertical direction), then scroll bar has arrived the boundary of end position.
In the said method, can also comprise after said scroll bar arrives the border, continue to move, then click thing distance that moves and the distance (promptly showing the blank distance that moves) that the scroll bar content moves and just be not linear relationship to boundary direction if click thing.When scroll bar arrives left margin with scroll bar horizontal ordinate mobile content and click the displacement P and the boundary length X of thing
MaxPoor (P-X
Max) (mm) be example, (P-X at this moment greater than 0
Max) (mm) and the relation between the distance X (mm) that moves of content shown in Fig. 2 (a), particularly, X=a * { 1-a/ [a+ (P-X
Max)], wherein a is the elasticity maximal value, can confirm according to user operation habits or use experience, sets a=20mm in this example; Perhaps when scroll bar arrives left margin; Is example with scroll bar horizontal ordinate mobile content and the displacement P that clicks thing less than 0, this moment P (mm) and and the distance X (mm) that moves of content between relation shown in Fig. 2 (b), particularly; X=a * [1+a/ (a-P)]; Wherein a is the elasticity maximal value, can confirm according to user operation habits or use experience, sets a=20mm in this example.
The embodiment of the invention is with the scroll bar of ordinate direction and specifically have 15 rolling contents to be example, and is as shown in Figure 3, comprising:
The position and the corresponding time of thing clicked in step 31, record; As writing time the 10:52:01 correspondence position be (0,1); The 10:52:03 correspondence position is (0,2);
Step 32, the position corresponding with the final time of said record, position when lifting according to the click thing obtain linear velocity initial value (not being 0); As the position when clicking thing and lifting is (0,10), and the corresponding time is 10:52:05, and then obtaining the linear velocity initial value is (10-2)/2s=4;
Step 33, adjust the initial value of said linear velocity successively, obtain corresponding displacement, and, be 0, choose corresponding contents up to said displacement according to the scroll bar in the said displacement adjustment scroll control according to the acceleration of setting; As to set acceleration be 1, and then initial displacement is 4-1=3, and the adjustment scroll bar rolls 3, in-position (0,13); This moment, linear velocity was reduced to 3, continued to obtain displacement 3-1=2, and the adjustment scroll bar rolls 2, in-position (0,15); At this moment linear velocity is reduced to 2; Obtain displacement 2-1=1; Scroll bar has been rolled to the border; If a is set at 20mm among Fig. 2 (a); Can show that then blank also mobile
linear velocity this moment is reduced to 1 this moment, obtain displacement 1-1=0, then turn back to the 15th content place of scroll bar.Process turning back to the 15th content of scroll bar can playing animation or picture
Embodiment of the present invention also provides a kind of technical scheme that realizes the device of content choice based on scroll control; This device can be arranged in the existing scroll control; Also can be arranged in the newly-designed scroll control through program, as shown in Figure 4, comprising:
Logging modle 41 is used to write down position and the time corresponding of clicking thing;
Particularly, said click thing can be finger or the writing pencil on the touch apparatus, also can be mousebutton;
Further, at first, the setting-up time interval, the said time interval can be 1s, also can be 10 millimeters, confirms according to user operation habits or use experience; Then, every position and time corresponding of clicking thing of noting at a distance from the said time interval: specifically can set up two-dimentional rectangular coordinate system, note coordinate figure and the time corresponding of clicking thing.
Linear velocity acquisition module 42 is used for the linear velocity initial value of position when lifting according to the said click thing position acquisition corresponding with the final time of said logging modle 41 records;
Position when lifting as if the click thing particularly, is (X
n, Y
n) the corresponding time is T
n, the final time of record is T
N-1Corresponding position is (X
N-1, Y
N-1), then the initial value of linear velocity be (| X
n-X
N-1|, | Y
n-Y
N-1|)/(T
n-T
N-1); If the linear velocity initial value is 0, then explain and selected the content that needs when the user lifts, and if the linear velocity initial value is not 0, then explanation also wants to continue to select other content when lifting, and promptly just can understand user's selection intention according to said linear velocity initial value.
Particularly, at first, preestablish acceleration; Said acceleration can be 1 (displacement/second), also can be 1 (displacement/millisecond), and confirm according to user operation habits or use experience: for example: horizontal ordinate directional ray speed initial value is 5mm/ms; No ordinate directional ray speed initial value; The setting acceleration is 1mm/ms, because the time is the unit interval so can ignore chronomere, then initial displacement is 5-1=4mm; Just adjust scroll bar rolling 4mm in the scroll control, this moment, linear velocity also was reduced to 4mm/ms; Continuing to obtain displacement is 4-1=3mm, continues scroll bar rolling 3mm in the adjustment scroll control, and this moment, linear velocity also was reduced to 3mm/ms; By that analogy, be reduced to 0mm/ms, then select scroll bar through repeatedly moving the content on the position, back up to linear velocity.Just reached a kind of inertia effect this moment, and promptly when user's finger streaked on a control that has a scroll bar, scroll bar not only will be followed user's finger and rolled, and when user's finger leaves and has certain initial velocity, can continue rolling and stop slowly.
Further, if the scroll bar in the scroll control arrives the border, be 0 o'clock then at said displacement, turn back to the boundary of the scroll bar in the said scroll control, choose content corresponding.For example: horizontal ordinate directional ray speed initial value is 5mm/ms; No ordinate directional ray speed initial value, the setting acceleration is 1mm/ms, because the time is the unit interval so can ignore chronomere; Then initial displacement is 5-1=4mm; Just adjust scroll bar rolling 4mm in the scroll control, but the only remaining 3mm of scroll bar horizontal ordinate corresponding contents can show at this moment, is reduced at 0 o'clock at said displacement so; Turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.The process on the scroll bar border in turning back to said scroll control can playing animation or picture.
Perhaps,
If when scroll bar arrives the border,, it is not 0 o'clock then at the said displacement that successively decreases gradually if the scroll bar in the said scroll control arrives the border; Show blank gradually; Be reduced at 0 o'clock at said displacement, turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.For example: ordinate directional ray speed initial value is 5mm/ms, no horizontal ordinate directional ray speed initial value, and the setting acceleration is 1mm/ms; Because the time is the unit interval so can ignore chronomere, then initial displacement is 5-1=4mm, just adjusts scroll bar rolling 4mm in the scroll control; But the only remaining 3mm of scroll bar horizontal ordinate corresponding contents this moment; The displacement that basis is successively decreased gradually after scroll bar arrives boundary position so shows blank gradually, is reduced to 0 o'clock up to said displacement; Turn back to the boundary of the scroll bar in the said scroll control, choose corresponding contents.The process on the scroll bar border in turning back to said scroll control can playing animation or picture.Just reached a kind of elastic effect this moment, when promptly scroll bar arrives the border, if finger continues to drag to the border; Then content displacement is not directly proportional with finger displacement, but presents the pulling force effect of spring-like, and it is big more to be specially finger displacement; The resistance that receives when content moves is just more little, and the maximal value that has a content to move, and promptly no matter points and how far moves; The distance that content moves can only be infinitely near this maximal value, and can not meet or exceed this maximal value.
Particularly; The existing control that has scroll bar is all realized rolling function (like ListBox or RichEditBox) through ScrollViewer (roll events) for basic control; As long as the rolling behavior of control ScrollViewer; The operation of clicking thing promptly may be used on the control of other tape spools; Usually all being HorzontalOffset (horizontal component) and the position that VerticalOffset (vertical component) attribute obtains HScrollBar and the vertical position of scroll bar through visit ScrollViewer, is example with the mobile of vertical component further, judges that the process on scroll bar arrival border can comprise:
double?oldVerticalOffset＝this._scrollViewer.VerticalOffset；
double?p＝oldVerticalOffset-y；
If p is less than 0, then scroll bar has arrived the boundary of starting position; If p is greater than scrollViewer.ScrollzbleHeight (being the maximum displacement of vertical direction), then scroll bar has arrived the boundary of end position.
Further after said scroll bar arrives the border, continue to move, then click thing distance that moves and the distance (promptly showing the blank distance that moves) that the scroll bar content moves and just be not linear relationship to boundary direction if click thing.When scroll bar arrives left margin with scroll bar horizontal ordinate mobile content and click the displacement P and the boundary length X of thing
MaxPoor (P-X
Max) (mm) be example, (P-X at this moment greater than 0
Max) (mm) and the relation between the distance X (mm) that moves of content shown in Fig. 2 (a), particularly, X=a * { 1-a/ [a+ (P-X
Max)], wherein a is the elasticity maximal value, can confirm according to user operation habits or use experience, sets a=20mm in this example; Perhaps when scroll bar arrives left margin; Is example with scroll bar horizontal ordinate mobile content and the displacement P that clicks thing less than 0, this moment P (mm) and and the distance X (mm) that moves of content between relation shown in Fig. 2 (b), particularly; X=a * [1+a/ (a-P)]; Wherein a is the elasticity maximal value, can confirm according to user operation habits or use experience, sets a=20mm in this example.
The concrete implementation of the processing capacity of each module that comprises in the said apparatus is described in method embodiment before, no longer is repeated in this description at this.
Corresponding displacement obtained corresponding linear velocity initial value before and after the embodiment of the invention was lifted through the click thing; Thereby and according to said initial value scroll bar is carried out rolling operation and choose content corresponding; Guaranteed the user at the edge that arrives touch-screen or mouse still can choose needed content when not having the operating space; And satisfied as the user and want when the 1st of scroll bar selected the content of the 50th of scroll bar; Move the bigger linear velocity initial value of acquisition fast through clicking thing, thereby can arrive the required content of user fast, solved and worked as the scroll bar content more for a long time; The trouble that the user must select one by one; Thereby can obtain the inertia effect that bigger linear velocity initial value is accomplished the fast moving of scroll bar content through moving rapidly of finger or mouse, make things convenient for the user, and show when arriving the border and blankly arrived the scroll bar border with the prompting user; When displacement is 0 or click the elastic effect that turns back to the content place, border of scroll bar when thing lifts again, improved sense of experience of users.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
