[embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
With reference to Fig. 1, Fig. 1 is the schematic block diagram of hand-written input system of the present invention.In the present embodiment, hand-written input system 10 comprises processor 11, touch-screen 13 and program storage 17.Wherein, be integrated with display unit and hand input device on the touch-screen 13, hand input device is interior at certain time intervals (for example, 10ms) handwriting tracks is carried out coordinate figure sampling and the coordinate figure of being gathered is sent into processor 11, and processor 11 is handled and controlled display unit according to the programs of solidifying in the program storage 17 and shows to coordinate figure.In addition, hand-written input system 1 can also comprise and is used for the keyboard 19 that random access memory 15 that data are kept in and user manually import.
In handwriting input, processor 11 according to hand input device continuously input two coordinate figures on the display unit with and corresponding 2 points of these two coordinate figures (point 1 and point 2) between line be center line demonstration parallelogram.Referring to Fig. 2, Fig. 2 utilizes two continuous input coordinate values to form the synoptic diagram of parallelogram one embodiment.In the present embodiment, processor 11 be not adopt traditional treatment method on display unit will with two continuously the corresponding points 1 of coordinate figure and the point 2 of input directly connect into line segment, but show on the display unit with put 1 and the line put between 2 be the parallelogram of center line.The width of this parallelogram is determined by live width w.The coordinate of four summit a, b, c and d of parallelogram (Xa, Ya), (Xb, Yb), (Xc, Yc) and (Xd, Yd) with the coordinate of point 1 and point 2 (X1, Y1) and (X2, Y2) and the relation of live width w determine by following formula:
Xa＝X1-w/2，Ya＝Y1-w/2；
Xb＝X1+w/2，Yb＝Y1+w/2；
Xc＝X2+w/2，Yc＝Y2+w/2；
Xd＝X2-w/2，Yd＝Y2-w/2。
By above-mentioned formula, can be by point 1 and point 2 unique definite parallelogram.By the way, not point 1 and put simple wires between 2 what show on the screen, but a well-determined parallelogram.Along with writing pencil constantly motion on hand input device, hand input device is constantly sampled to its coordinate figure, processor 11 just can show a plurality of parallelogram according to sampled data on display unit, make the literal that demonstrates have certain vigour of style in writing effect.
In the above-described embodiments, hand input device preferably adopts the pressure sensitive hand input device.The pressure sensitive hand input device is also sampled to the force value on it when hand-written trajectory coordinates value is sampled, and processor 11 is according to this design of pressure live width w.For example, live width w was also corresponding when pressure reduced diminishes, and the parallelogram width that is presented on the display unit is diminished, thereby embodies the effect of starting writing.Also the phase strain was big for live width w when pressure increased, and the parallelogram width that is presented on the display unit is broadened, thereby embodied a pen or change an effect.

C＝R+G+B
Three components that the user can preestablish initial point color C1 are respectively R1, G1 and B1, three components of terminating point color Cn are respectively Rn, Gn and Bn, and to set gradual change intensity be k, and the intermediate change look Cm that seamlessly transits gradually from color C1 to color Cn and three primary color components Rm, Gm and Bm can calculate with following formula:
Rm＝R1+(Rn-R1)m/k；
Gm＝G1+(Gn-G1)m/k；
Bm＝B1+(Bn-B1)m/k；
Cm＝Rm+Gm+Bm；
Wherein m is a positive integer.
By adopting the combination of parallelogram stack and color gradient, when on display screen, showing parallelogram, the color of parallelogram is filled to the middle transition look that calculates, the literal that is formed by stacking by parallelogram will be very smooth like this, thus the handwriting input that realization has the vigour of style in writing and color effect.
