[embodiment]
In one embodiment, as shown in Figure 1, a kind of cursor assisted location method may further comprise the steps:
Step S102 follows the tracks of and detects the position of cursor on display screen, generates the cursor event that shifts out when cursor is positioned at the edge of target input field, and described target input field is used for cursor and enters rear input instruction.
In the present embodiment, as shown in Figure 2, be provided with circular icon on the display screen 10, icon is target input field 20 in the zone that display screen 10 occupies.The user is by mobile cursor target approach input field 20, and the function key on then clicking the mouse can be inputted command operating.For example, left mouse button is double-clicked 20 instructions of inputting " executive routine " in target input field, clicks the instruction that " popup menu " inputted in 20 of target input fields by mouse right button.
In the present embodiment, follow the tracks of first and detect the position of cursor on display screen, when the position that detects cursor is positioned at the edge of target input field 20, then generate the cursor event that shifts out.Shift out the cursor event and can use symbol, electric signal or coded representation, and will shift out the cursor event and send to disposal system.
In the present embodiment, the step that follow the tracks of to detect the position of cursor on display screen also comprises: whether the current location of judging cursor is positioned at target input field 20, if, then change the display effect of target input field 20, otherwise, the display effect of recovery target input field 20.For example, be positioned at target input field 20 if detect cursor, then target input field 20 is highlighted and/or amplify and/or vibrations, if when detecting cursor and being in other positions on the display screen 10, then will stop highlighted and/or amplify and/or vibrations.When the icon 20 on the display screen 10 was a lot, above-mentioned way can make the user can know easily the position of the icon 20 of choosing, and experienced thereby improve the user.
Step S104 detects the described cursor event that shifts out, and detects simultaneously the slip behavior of mouse, and the slip behavior of described mouse makes cursor have the mobile vector acceleration; Within the locking time of setting, be locked in the target input field cursor mobile according to described mobile vector acceleration.
In the present embodiment, as shown in Figure 2, the slip of mouse makes cursor have mobile vector acceleration a, when cursor was in the edge of target input field 20, the mobile vector acceleration can be decomposed into target input field 20 in the parallel parallel component of acceleration of the tangent line of cursor position and the vertical acceleration component vertical with described tangent line.
For example in the present embodiment, in certain input, when cursor is positioned at the position of C on the edge of target input field 20, has detected and shifted out the cursor event, and recorded cursor in the initial movable speed of C position.Simultaneously, the slip that detects mouse makes cursor at the mobile vector acceleration a of display screen 10 generations, and a has x and two components of y.Wherein, x is parallel to target input field 20 at the parallel component of acceleration of the tangent line of C position, and y is perpendicular to the vertical acceleration component of target input field 20 at the tangent line of C position.
If move into the vertical acceleration component y of target input field 20 directions and be on the occasion of, the vertical acceleration component y that shifts out target input field 20 directions is negative value.Within the locking time of setting, when vertical acceleration component y is negative value, cursor is locked in the edge of target input field 20, soon the initial movable speed vertical velocity component parallel with vertical acceleration component y of cursor is set to 0 this moment, and allows cursor move along 20 edges, target input field with the initial movable speed PARALLEL VELOCITY component vertical with vertical acceleration component y; Then only by parallel component of acceleration x positioning cursor.When vertical acceleration component y be on the occasion of the time, allow cursor move freely with this moment initial movable speed, then by mobile vector acceleration a positioning cursor, even cursor moves freely in target input field 20.After locking time, cursor moves freely.

0To t
2Time be locking time, the duration of locking time is predefined parameter.
At t
0To t
1Time interval, vertical acceleration component y is negative value, i.e. the slip of mouse makes the oriented vertical acceleration component y that shifts out the direction of target input field 20 of cursor.Then, according to mobile vector acceleration a positioning cursor the time, only the parallel component of acceleration x by a locates cursor.The method of the position of the cursor that moves take initial velocity according to acceleration location is as simple mathematical computations, do not do in detail at this and explains.
Because parallel component of acceleration x is parallel to target input field 20 through the tangent line of position C, so cursor must be mobile at the edge of target input field 20, moves so also can say the edge that cursor is locked in icon 20 herein.As shown in Figure 2, at process t
0To t
1Time period after, cursor movement is to the position of D.
At t
1To t
2Time interval, vertical acceleration component y become on the occasion of, i.e. the slip of mouse makes the oriented acceleration that moves towards the direction of icon 20 of cursor.Then, according to mobile vector acceleration a positioning cursor, namely cursor is from t
1Constantly rise, no longer the edge along target input field 20 moves, but moves at the internal freedom of target input field 20.
In another embodiment, if at t locking time
0To t
2Time interval in, the vertical acceleration component y of a is negative value, then at t
0To t
2Time interval in, cursor rotates at the edge of target input field 20 always.And t
2Constantly, then according to mobile vector acceleration a positioning cursor, namely cursor moves freely.
Therefore, in sum, at t locking time
0To t
2Time interval in, according to mobile vector acceleration a cursor is locked in the 20 interior movements of target input field.
In the present embodiment, when judging the direction of vertical acceleration component y, whether also to judge vertical acceleration component y greater than default accekeration, if, then will be set as 0 locking time, otherwise, will be set as the default time locking time.
That is to say before move the inside that cursor is locked in target input field 20, judge first whether cursor has the trend of leaving target input field 20 with larger acceleration, if, then stop locking, allow cursor freely leave, otherwise, continuing within locking time, the edge that cursor is locked in target input field 20 moves until cursor 20 interior movements or the enough large vertical acceleration component y that shifts out target input field 20 is arranged to the target input field.
In the present embodiment, extension is provided with auxiliary positioning district 30 around the icon 20.Auxiliary positioning district 30 is preferably annular, and its large I is regulated as required.
