(1) by [B (0,0), B (1,0)], [B (0, n), B (1, n)] two point coordinates calculate 2 points of distance；
(2) above-mentioned distance is removed in the touch movement speed of value acquisition adjacent point-to-point transmission on track of timer J, and timer J is clear
Zero, restart timing；
(3) after being obtained with the touch movement speed of the maximum person's handwriting of stroke presentation width D rawWidth*k divided by adjacent point-to-point transmission
Width is presented in person's handwriting at a little, is A (n) assignment；If speed is less than a certain threshold values, width is presented with maximum person's handwriting
DrawWidth*k is that wide A (n) assignment of pen is presented in the person's handwriting of latter point；
(4) according to [B (0,0), B (1,0)], adjacent 2 points of coordinate value on the track [B (0, n), B (1, n)], with equidistant interpolation
Method, be inserted into n-1 point in point-to-point transmission, calculate coordinate, and assignment is to [B (0,1), B (1,1)] ... [B (0, n-1), B (1,
N-1 in)]；Width A (0) is presented according to adjacent 2 points of person's handwriting on track, the value of A (n) calculates n-1 with linear method and inserts
Width is presented in person's handwriting at access point, is A (1) ... A (n-1) assignment；
(5) according to adjacent two point coordinates on track [B (0,0), B (1,0)], two tracing point lines [B (0, n), B (1, n)], are calculated
Vertical line and transverse coordinate axis forward direction angle, then be added with G to obtain this person's handwriting and person's handwriting inclination angle P be presented；
(6) pen is carried out to [B (0, h), B (1, h)] of the n group consecutive points in n+1 point, [B (0, h+1), B (1, h+1)] at 2 points
Mark is presented (0<=h<=n-1)：
It is needed 1. width A (h+1) is presented according to coordinate, the person's handwriting at P and point [B (0, h+1), B (1, h+1)] and calculates when person's handwriting is presented
3 points of two auxiliary magnets, 4 points of the coordinate wanted are [C (0,2), C (1,2)], [C (0,3), C (1,3)] assignment；
2. if point [B (0, h), B (1, h)] is the first stroke of a Chinese character point of unicursal, then according at P and point [B (0, h), B (1, h)] coordinate,
Person's handwriting is presented width A (h) (being at this moment the maximum person's handwriting presentation width of person's handwriting) and calculates two auxiliary magnets 1 needed when person's handwriting is presented
