In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Shown in Fig. 1, the preferred embodiment of primary handwriting hand input display method provided by the invention comprises following core procedure:
Elaborate above steps below in conjunction with Fig. 2-5.
Shown in Fig. 2, after handwriting input begins, determined after the position of initial point (calling " initial point " in the following text), at first to determine point that the next one scans with respect to step direction from initial point, that is, need clear and definite initial point from where near next analyzing spot.In Fig. 2, with initial point (x0, y0) set up rectangular coordinate system for true origin, writing pencil can continue to extend after initial point to all around, the next analyzing spot that writing pencil produces can drop in the 1-8 zone on (8 zones) or the A-H line segment (8 line segments) totally totally, in step 10, at first determine the zone at a back analyzing spot (previous analyzing spot is an initial point) place exactly, and then definite step direction.Below enumerate a preferred implementation set forth sweep after how determining described point (Xn, position Yn):
(1) as if Xn-X0＞=0, the position that sweeps described point after then can determining is in first and second quadrant (comprising axis of ordinates);
(2) as if Yn-Y0＞=0, the position that sweeps described point after then can further determining is in first quartile (comprising H, B).
(3) if (Yn-Y0)/(Xn-X0)＞1, the position that sweeps described point after then can further determining is in 1 zone;
If (Yn-Y0)/(Xn-X0)＜1, the position that sweeps described point after then can further determining is in 2 zones.
If (Yn-Y0)/(Xn-X0)=1, the position that sweeps described point after then can further determining is on the A line segment;
If (Yn-Y0)/(Xn-X0)=0, the position that sweeps described point after then can further determining is on the B line segment;
If Xn=X0 and Yn-Y0＞=0, the position that sweeps described point after then further determining is on the H line segment;
Therefore, can find by above-mentioned example no matter how writing pencil moves, can both be that initial point is set up rectangular coordinate system with the previous scanning point, by to above-mentioned similar comparison and calculating, sweep the position of described point and then definite step direction after determining.
