The application software downloaded from third party device or server, wherein the concrete type and content of application software can bases
Actual conditions setting can be realized in general, the application software has electronic whiteboard function by electronic whiteboard function: write,
The functions such as drawing, annotation, courseware development and displaying broadcasting.There is intelligent interaction blank in embodiment writing brush person's handwriting to draw function
It can, it can convert person's handwriting similar with Brush calligraphy for the writing operation of user and show on a display screen.
Wherein, when specific operation, user can first open corresponding software for editing (such as electronic whiteboard), and start writing brush book
Function is write, then the written handwriting that subsequent user is drawn in software for editing is converted into writing brush person's handwriting.
S102 operates according to the writing, obtains multiple sampled points.
In the present embodiment, for user when touch-sensitive display panel enterprising running hand write operation, the intelligent interaction plate can
A touch-control point sampling is carried out every the scheduled sampling time, when sampling, can get the touch-control letter of current sampled point
Breath, wherein touch information includes at least the coordinate of each sampled point.
S103 draws corresponding with the sampled point of this predetermined number the sampled point that every predetermined number continuous acquisition obtains
Person's handwriting unit.
S104 shows the person's handwriting unit, with the multiple person's handwriting unit combination producing writing brush person's handwritings obtained according to drafting.
In the present embodiment, user will constantly generate sampled point when continuous writing operation, and the intelligent interaction is flat
Several sampled points that plate can obtain continuous acquisition are drawn by scheduled rendering algorithm (Bezier algorithm such as can be used)
System, obtains person's handwriting unit corresponding with these sampled points.
For example, it is assumed that predetermined number is set as 3, then the intelligent interaction plate is after three sampled points of every generation, with regard to root
A person's handwriting unit is generated according to these three sampled points, after waiting 3 sampled points of regeneration, then draws and generates a person's handwriting unit, such as
This is constantly repeated, until the writing operation of user terminates.300 samplings are produced altogether after operating such as the writing of user

It needs and sets, the present invention is not specifically limited.
Wherein, it should be noted that during being drawn using rendering algorithm, according to actual rendering algorithm
Difference needs different rendering parameters, these can be depending on the demand of rendering algorithm, these schemes are in guarantor of the invention
Within the scope of shield.
In conclusion in the drawing process of writing brush person's handwriting, being generated according to the sampled point of every predetermined number in the present embodiment
One person's handwriting unit, then combine to form final writing brush person's handwriting by person's handwriting unit, compared with the existing methods, redundancy is not present
Drafting, draw it is high-efficient, and due to each person's handwriting unit be by draw generate rather than generated by textures,
It freely scales and only needs to be repainted according to the case where scaling, will not influence the clarity of display.
On the basis of the above embodiments, in a preferred embodiment of the invention, after step s 102, S103 it
Before, further includes:
S105, according to the spacing between adjacent sampled point, the speed of each sampled point is passed through in estimation.

The corresponding person's handwriting unit of the sampled point of this predetermined number.
Wherein, the spacing between two neighbouring sample points can be calculated according to the coordinate of each sampled point, further according to spacing
And the sampling time can estimate the time by each sampled point.
Clearly as the sampling time is fixed, therefore spacing is longer, then illustrates that writing speed is faster, i.e., speed and
Away from positive correlation.
For example, settable speed v=b*d/t.Wherein, spacing of the d between adjacent sampled point, t are sampling time, b
For empirical coefficient.
Wherein, writing pressure value is negatively correlated with speed, i.e., in general speed is faster, and it is smaller to write pressure value.
For example, in a concrete implementation mode, in writing pressure value P=n-a*v of each sampled point；Wherein n is
The maximum width of person's handwriting, v are in the speed by the sampled point, and a is empirical coefficient.
