In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit 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), to determine that at first point that the next one scans is with respect to the step direction from initial point, that is, need clear and definite initial point from where to close next analyzing spot.In Fig. 2, with initial point (x0, y0) set up rectangular coordinate system for true origin, writing pencil can be to continuing extension all around after initial point, 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 exactly the zone at a rear analyzing spot (previous analyzing spot is initial point) place, and then definite step direction.Below enumerate a better embodiment and set forth the position that sweeps described point (Xn, Yn) behind the how to confirm:
(1) 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) 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, sweeping the position of described point after then can further determining is in 2 zones.
If (Yn-Y0)/(Xn-X0)=1, sweeping the position of described point after then can further determining is on the A line segment;
If (Yn-Y0)/(Xn-X0)=0, sweeping the position of 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, and can both set up rectangular coordinate system take previous scanning point as initial point, by to above-mentioned similar comparison and calculating, sweep the position of described point and then definite step direction after determining.
