Determine the functional mode that user selects, and the bottom mapped under this functional mode performs instruction; Set up described bottom and perform the call relation of punctuating between action that instruction and user will operate; After action that what user to be monitored operated on the touchscreen punctuate, perform instruction according to described bottom and process; This is treated to identifying processing, choose process, any one or combination in any in mark process or convergent-divergent process.
In some illustrative embodiment, described convergent-divergent process, specifically comprises:
Identify the track of punctuating mated with described action of punctuating, the trajectory direction of track of punctuating described in determining; Determine amplifieroperation or reduction operation according to described trajectory direction, and perform the operation determined in a document.
Such as:
The entering and exiting of zoom mode, adopting consecutive click chemical reaction starts window Scalable patterns for twice, then adopting consecutive click chemical reaction terminates window Scalable patterns for twice, System recover original window size;
The mitigation and amplification of zoom mode, forms track and moves along positive hour hands, be judged to be amplifieroperation, amplify current window; Form track along mobile counterclockwise, be judged to be reduction operation, current window is reduced.
Compare that to carry out amplifieroperation with multiple combinations of fingers easier, the personage that finger is inconvenient can be suitable for.
In some illustrative embodiment, before the operation that described execution is determined, also comprise: the size of the radian of the circular arc formed according to described track of punctuating, determine the zoom factor of described amplifieroperation or reduction operation; Described operation is performed according to described zoom factor.
Such as: the ratio of the angle that radian is formed and standard radian (suppose 60 degree, adjustable) be Scalable ratio of punctuating, maximum default is 180 degree (-3≤enlargement factor≤3).
In some illustrative embodiment, the circular arc that track of punctuating described in described basis is formed, fit standard circle, as selected zone, specifically comprises: according to the described circular arc formed, form described standard round according to Bi_arc fitting method or least square fitting.
In some illustrative embodiment, formed in the process of described standard round with the matching of described Bi_arc fitting method, comprising: on the described circular arc formed, choose at least 4 points, carry out angle calculation with described at least 4 points, determine multiple candidate circles; Matching is carried out to described multiple candidate circles, determines described standard round.
Bi_arc fitting method algorithm is as follows:
As shown in Figure 3, bicircular arcs disposal route gets 4 points of listing curve successively.
Determine arc section P2T and TP3 between P2P3, must provide P1, P2, P3 and P4 be totally 4 points.P1 ~ P4 point be distributed with multiple situation, but through suitably process after can be generalized into kind of the situation of two shown in Fig. 4.
1. situation is the homonymy of P1, P4 point at P2, P3 point line, and the circular arc of institute's matching, also at the homonymy of line, is called homonymy circular fitting (see Fig. 5).Situation P1 2., P4 point is at the heteropleural of P2, P3 point line, and two circular arcs of institute's matching are circumscribed each other, are called heteropleural circular fitting.
The formula proving of homonymy circular fitting is as follows:
As Fig. 5 shows, cross the vertical line P2M that P2 point makes the angular bisector P2A2 of ∠ P1P2P3, cross the vertical line P3M that P3 point makes the angular bisector P3A3 of ∠ P2P3P4, cross the angular bisector P2N that P2 point remakes ∠ P3P2M, cross the angular bisector P3N that P3 point makes ∠ P2P3M, the intersection point N crossing P2N and P3N makes the vertical line NP of P2P3, NP and P2A2 and P3A3 meets at O2 respectively, O3 point, respectively with O2, O3 is the center of circle, O2P2, O3P3 is that radius makes circular arc C 2, C3, 2 circular arcs are tangential on N point, and P2M and P3M is also respectively at P2 point and P3 point and C2, C3 is tangent, then arc P2N and arc NP3 constitutes P2, line is approached between P3 set point.
If the radius of C2, C3 circular arc is respectively r2, r3, then can derive:
r
2＝[dcosv(sinu+cosv)-dsinv(cosu-sinv)]/h
r
3＝[dcosv(sinq+cosv)-dsinv(cosq-sinv)]/h
In formula, h=(cosq-sinv) (sinu+cosv)-(sinq+cosv) (cosu-sinv); D is the distance between P2 point and P3 point; Q, u and v are vector respectively
and
and the angle between x-axis forward.
Therefore, by the P1 ~ P4 point coordinates value provided, the value of d, q, u, v can be determined, so just can determine r2, r3.The coordinate values of center of circle O2, O3 and N point is determined again according to given data.
The similar homonymy circular arc of derivation of heteropleural circular arc computing formula, does not repeat them here.
Bi_arc fitting method can ensure that circular approximation line is crossed and provide a little, and continuous in each point first order derivative.Its computing method are simple, and strong adaptability, has good fitting precision.
Least square method:
Different from Bi_arc fitting method, the approximate circular arc that it fits to not necessarily will by respectively providing a little.As Fig. 6 shows, approximate circular arc R and each provide a little between the quadratic sum of absolute error be minimum.
Circular arc can limit with " tolerance " ta artificially with the error of some exact value, is all with in scope in " tolerance " of R ± ta if all by the point of matching, then think that R circular fitting is successful.
" tolerance " sets according to actual needs and artificially, generally selects very little numerical value, as 0.01mm.If " tolerance " is less, then approximation accuracy is higher, and the point that every bar arc section can meet precision reduces, and therefore total circular arc hop count will increase.Otherwise then approximation accuracy reduces, every section of circular arc can meet the some increase of precision, and therefore total circular arc hop count will reduce.
The computing method of least square method are as follows:
As Fig. 6 shows, the central coordinate of circle of approximate circular arc is (a, b), and radius is R, (x
i, y
i) be the coordinate of any point on curve, then can try to achieve:
a＝Δa/a；b＝Δb/b
Some matching circular arcs can be obtained by the matching of a Groups List curve.Once mention approximate circular arc to be above not necessarily by and to provide a little, therefore just there is the connection problem in some circular arcs between adjacent circular arc.Easier solution such as Fig. 7 shows.
If P

1, radius is R
1.P
