S201, terminal device gathers according to the touch point of time interval Δ T to user of presetting, and design sketch is see Fig. 2.
S202, mobile terminal determination current character write region;
The coordinate range in the up-to-date coordinate of the person's handwriting touch point determined and the region of current input characters is compared, if this person's handwriting touch point is outside described coordinate range, then according to the coordinate range in the region of the current input characters of the coordinate renew of this person's handwriting touch point;
Specific implementation process is: by the coordinate of first touch point stored in one group of named variable, and the implication of this group named variable is respectively left margin, right margin, coboundary, lower boundary;
The coordinate of newly-increased point is compared with named variable, if the horizontal ordinate of newly-increased point is less than left margin, or is greater than right margin, by this abscissa value stored in corresponding left margin or right margin; If the ordinate of newly-increased point is less than lower boundary, or is greater than coboundary, by this ordinate value stored in corresponding lower boundary or coboundary; What namely described named variable stored is the boundary information be input to so far.
S203, terminal device calculates adjacent touch point (X
i, Y
i) and (X
i-1, Y
i-1) between distance, and according to distance computing velocity S
i;
Screen area can be divided into coordinates regional by usual terminal device, and there is a corresponding coordinate each touch point, and the backstage of terminal device can calculate corresponding data according to the coordinate information of collection point.
Speed S
icomputing formula is
As Fig. 3, it is scene schematic diagram of the present invention.
S204, terminal device calculated description writing rate rate of change;
S
ifor the speed between up-to-date a pair touch point determined;
S
i-1for the speed between a pair touch point inputting before;
Δ S is S
iwith S
i-1velocity contrast;

According to described computing formula, the relation of percentage speed variation and live width can be understood as: when user accelerates to write, relative velocity rate of change R
ifor on the occasion of, R
ivalue larger, live width is narrower, and namely person's handwriting can be lighter; When user slows down writing speed, relative velocity rate of change R
ifor negative value, R
ivalue less, live width is wider, and namely person's handwriting can be denseer; The method is consistent with the writing style of user.
Especially, the live width between first pair of touch point can be preset as fixing value, also can according to the speed between first pair of touch point, according to the relation of the speed preset with live width, determines the live width of correspondence.
S206, the person's handwriting of this person's handwriting live width of terminal output display, and word is shown between two parties;
The person's handwriting of this person's handwriting live width of terminal output display;
When not collecting touch point in the time interval that terminal detects continuous multiple Δ T, terminal thinks user's current character end of input;
Terminal, according to the border of S202 step determination input characters, adjusts the viewing area of word and is shown between two parties by word.
Specific embodiment 2: because the temporal frequency of sampling is fixing, live width is calculated according to user writing percentage speed variation, the change calculations live width of the distance between mathematically can being reduced to according to the touch point of user, namely the step S203 of specific embodiment 1, S204, S205 are simplified, the rate of change of distance between the touch point directly calculating user, according to this rate of change determination person's handwriting live width.The method process is more simple, decreases the computational load of terminal device.
