Better, the corresponding live width of the touch speed of the touch speed of up-to-date definite person's handwriting line segment that described basis calculates, the front person's handwriting line segment of once determining and the front person's handwriting line segment of once determining, obtain the live width of described up-to-date definite person's handwriting line segment, specifically comprise:
Calculate the user at the touch speed of the up-to-date definite person's handwriting line segment relative velocity rate of change than the touch speed of the front person's handwriting line segment of once determining, according to the corresponding live width of this relative velocity rate of change and the front person's handwriting line segment of once determining, determine the live width of described up-to-date definite person's handwriting line segment.
Better, described corresponding live width according to this relative velocity rate of change and the front person's handwriting line segment of once determining, determine specifically to comprise the live width of described up-to-date definite person's handwriting line segment:
When this relative velocity rate of change be on the occasion of the time, the corresponding live width of the person's handwriting line segment of once determining before reducing according to the size of this relative velocity rate of change is as the live width of described up-to-date definite person's handwriting line segment;
When this relative velocity rate of change was negative value, the corresponding live width of the person's handwriting line segment of once determining before increasing according to the size of this relative velocity rate of change was as the live width of described up-to-date definite person's handwriting line segment.
Better, described corresponding live width according to this relative velocity rate of change and the front person's handwriting line segment of once determining is determined the live width of described up-to-date definite person's handwriting line segment, and specific formula for calculation is W
i=W
I-1(1-R
i);
Wherein:
W
iLive width for up-to-date definite person's handwriting line segment;
W
I-1Corresponding live width for the front person's handwriting line segment of once determining;
R
iBe the relative velocity rate of change.
Better, the method also comprises:
The coordinate range in the zone of the coordinate of up-to-date definite person's handwriting touch point and 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 zone of the current input characters of coordinate renew of this person's handwriting touch point; Wherein, the coordinate range in the zone of current input characters is that the coordinate of all touch points of current input characters is in the extreme value of upper and lower, left and right all directions.
Better, after this up-to-date definite person's handwriting line segment of output display, the method also comprises:
If the sampling in the described interval duration of default number does not obtain the person's handwriting touch point, determine that then the user is to current literal end of input;
Coordinate range according to the zone of current input characters shows this literal between two parties.
The below provides several specific embodiments of the invention.
Specific embodiment 1: utilize writing speed to adjust the thickness of person's handwriting, combine majority's writing style, can well be compatible all support the product of touch screens because writing speed can calculate according to sampled point.
Such as Fig. 2, a kind of implementation step of method of touch-screen output touch person's handwriting is as follows:
S201, terminal device gathers user's touch point according to default time interval Δ T, and design sketch is referring to Fig. 2.
S202, portable terminal determine the zone of writing of current literal;
The coordinate range in the zone of the coordinate of up-to-date definite person's handwriting touch point and 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 zone of the current input characters of coordinate renew of this person's handwriting touch point;
Specific implementation process is: deposit the coordinate of first touch point in one group of named variable, the implication of this group named variable is respectively left margin, right margin, coboundary, lower boundary;
Coordinate and the named variable of newly-increased point are compared, if the horizontal ordinate of newly-increased point perhaps greater than right margin, deposits this abscissa value in corresponding left margin or right margin less than left margin; If the ordinate of newly-increased point perhaps greater than the coboundary, deposits this ordinate value in corresponding lower boundary or coboundary less than lower boundary; Be the storage of described named variable be the boundary information that is input to so far.
S203, terminal device calculate adjacent touch point (X
i, Y
i) and (X
I-1, Y
I-1) between distance, and according to distance computing velocity S
i
Usually terminal device can be divided into coordinates regional with screen area, and there is the coordinate of a correspondence each touch point, and the backstage of terminal device can and calculate corresponding data according to the coordinate information of collection point.
Speed S
iComputing formula is
Such as Fig. 3, it is scene synoptic diagram of the present invention.
S204, terminal device calculated description writing rate rate of change;
S
iBe the speed between the up-to-date definite a pair of touch point;
S
I-1Be the speed between a pair of touch point of before input;
Δ S is S
iWith S
I-1Velocity contrast;
R
iBe the relative velocity rate of change;
Computing formula is
S205, terminal device calculating pen trace is wide;
W
iBe the live width between the up-to-date definite a pair of touch point;
W
I-1Be the live width between a pair of touch point of before input;
Computing formula is W
i=W
I-1(1-R
i)
According to described computing formula, the relation of percentage speed variation and live width can be understood as: when the user accelerates to write, and relative velocity rate of change R
iFor on the occasion of, R
iValue larger, live width is narrower, namely person's handwriting can be lighter; When the user slows down writing speed, relative velocity rate of change R
iBe negative value, R
iValue less, live width is wider, namely person's handwriting can be denseer; The method is consistent with user's writing style.
Especially, the live width between the 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 default speed and the relation of live width, determine the live width of correspondence.
S206, the person's handwriting of this person's handwriting live width of terminal output display, and literal shown between two parties;
The person's handwriting of this person's handwriting live width of terminal output display;
When not collecting the touch point in terminal detects time interval of continuous a plurality of Δ T, terminal is thought the current literal end of input of user;
Terminal is determined the border of input characters according to the S202 step, adjusts the viewing area of literal and literal is shown between two parties.
Specific embodiment 2: because the temporal frequency of sampling is fixed, calculate live width according to the user writing percentage speed variation, in the change calculations live width that can be reduced on the mathematics according to the distance between user's the touch point, namely step S203, S204, the S205 of specific embodiment 1 are simplified, directly the rate of change of the distance between calculating user's the touch point is determined the person's handwriting live width according to this rate of change.The method process is more simple, has reduced the computational load of terminal device.
