Embodiment
Referring to Fig.1 and 2, Fig. 1 is an a kind of preferred embodiment of the implementation method of original handwriting of the invention
Flow chart, Fig. 2 is a kind of module map of a preferred embodiment for realizing device for original handwriting of the invention.
The device of realizing of the original handwriting of the present invention includes determining module 11, and one is set up module 12 and one is filled out
Fill display module 13.
A kind of implementation method of original handwriting of the present invention includes step：
S1, determine step：Determine person's handwriting width and the simulation vectors at the end points of handwriting trace；
In the present invention, the determining module 11 specifically performs the operation for determining step S1, i.e., for determining handwriting trace
Person's handwriting width and simulation vectors at end points.The determining module 11 is typically a hand-written screen.The hand-written screen can be
Capacitance touch screen or electromagnetic touch screen.When the hand-written screen during electromagnetic touch screen, the determining module 11 also includes an electricity
Magnetic pen, the i.e. Special writing pen for being used cooperatively with electromagnetic touch screen.The hand-written screen can also be capacitance touch screen and electricity
The combination of magnetic touch-screen, while having capacitance touch writing and electromagnetic touch to write two kinds of functions.
In other embodiment, the hand-written screen can also be electric resistance touch screen etc..
The determining module 11 can also be the combination of a portable projecting apparatus and camera.Projecting apparatus is used in target
Region projection, people are write with hand in target area, and the track of camera identification human hand simultaneously converts the track of the hand of people
For word.People can also be write with club or special equipment in target area.Target area can be a wall or
It is a spatial dimension.
So that the determining module 11 is capacitance touch screen as an example, when finger is clicked on the touchscreen, capacitance touch screen can be adopted
Collect the specific contact area that user's finger extrudes capacitance touch screen, the contact area is taken into center of gravity or geometric center, by this
Center of gravity or the geometric center are defined as a touch point.When finger is slided on capacitance touch screen, touch point is over time
A continuous movement locus can be formed.
Equally, for electromagnetic touch screen, when time writer touches corresponding screen, electromagnetic touch screen can also connect this
Contact is defined as a touch point.When time writer is slided on electromagnetic touch screen, touch point can also form one over time
Continuous movement locus.
For electric capacity and the touch screen of electromagnetic combination, then mutually tied by foregoing two ways alternative, or two ways
Close and carry out obtaining touch point and movement locus after contrast processing.
Because capacitance touch screen or electromagnetic touch screen are to carry out a data acquisition at interval of very short time, because
This, actually aforementioned movement track is the line that multiple discrete points are connected into according to time sequencing.Generally for cause touch
Screen is sensitiveer, could be arranged to gather 120 data each second.That is, when there is touch object sliding on touch-screen, touch
Screen can gather touch object positional information on the touch-screen for 120 times in one second, that is, obtain the position of 120 touch points
Information.
In addition, for capacitance touch screen, in addition to obtaining the positional information of touch point, each touch point pair can also be obtained
The size for the contact area answered.To electromagnetic touch screen, the corresponding pressure size in each touch point can also be obtained.
Further, since each touch point position and sampling time point can be obtained, thus can also according to position and
Sliding speed, acceleration of each touch point of Time Calculation and the corresponding touch object of point of each sampling time etc..Ibid, to electricity
The rate of change of pressure can also be calculated electromagnetic touch screen with the rate of change of calculating contact area by holding touch-screen.
In writing, the sliding speed of the touch object such as hand or writing pencil is person's handwriting speed.What multiple touch points were formed
Track is handwriting trace.Described for ease of technology, touch point is referred to as sampled point in the present invention.In the present invention, person's handwriting speed
Degree can be turned to the real-time speed of sample point touch object by tool；The distance between namely adjacent sampled point divided by adjacent
The time difference of sampled point generation time point obtains numerical value.
To a specific sampled point Dm, the parameter that sampled point Dm has can include following one or more：
Pm, pressure value during sampled point Dm；Person's handwriting speed at Vm, sampled point Dm；Person's handwriting acceleration at Am, sampled point Dm；Sm, is adopted
Contact area at sampling point Dm.
In a kind of implementation method of original handwriting of the invention, determine that step S1 also includes step：
S11, the end points for judging handwriting trace
Touch-screen is according to time sequencing, when setting up a handwriting trace to multiple sampled points, first sampled point and last
One sampled point is the end points of handwriting trace.First sampled point is defined as start and end point, and last sampled point orientates end as
Point.In writing, touch object is generally touched to first sampled point referred to as start and end point during touch-screen；By touch object from
Open last sampled point referred to as distal point during touch-screen.
Person's handwriting width at S12, acquisition end points；
The width of the person's handwriting of screen display when person's handwriting width is writing.Specifically, each sampled point is corresponded to, by this
Sampled point and perpendicular to the line of the sampled point and an adjacent sampled point line, the length with the line segment of the lap of the person's handwriting
Degree.To each sampled point, an adjacent sampled point can be a forward in time sampled point, or can be
A sampled point on time rearward.Fig. 3 is refer to, Fig. 3 is the person's handwriting effect signal in a preferred embodiment of the invention
Figure.Equipment 1 shows written handwriting D and carries out person's handwriting B obtained by pixel filling processing according to written handwriting D.Handwriting trace D bags
Include the sampled point D1 ... Dm ... Dx according to time-sequencing；When with the company of forward in time a sampled point and current sampling point
When the person's handwriting width at sampled point Dm is determined based on line, it is, by sampled point Dm-1 and sampled point Dm lines.At sampled point Dm
Person's handwriting width be Wm, corresponding the wide line section is Lm.Then a wide line section Lm passes through through sampled point Dm, perpendicular to sampled point
Dm-1 and sampled point Dm line.
Generally, when handling handwriting trace, sampled point Dm is located at a wide line section Lm center.That is, when one book of acquisition
When writing track, gray scale filling can be symmetrically carried out to the both sides of track so that the person's handwriting sense of reality of display is stronger.
Start and end point does not have a time posterior sampled point without time upper first sampled point, distal point, therefore,
In the present embodiment, the corresponding person's handwriting width in start and end point is：By the start and end point and perpendicular to the start and end point and adjacent one
The line of individual sampled point line, the length with the line segment of the lap of the person's handwriting；Now, an adjacent sampled point is and only had
For relative to a sampled point on the start and end point time rearward.The corresponding person's handwriting width of distal point is：By the distal point and
Perpendicular to the distal point and the line of an adjacent sampled point line, the length with the line segment of the lap of the person's handwriting；Now,
An adjacent sampled point is and is only relative to a distal point time upper forward sampled point.In figure 3, start and end point
For D1, distal point is Dx.Person's handwriting width at sampled point D1 is W1, and corresponding the wide line section is L1；Person's handwriting at sampled point Dx
Width is Wx, and corresponding the wide line section is Lx.
Person's handwriting width can be the value of a default default value or change.In the present embodiment, person's handwriting is wide
The value of preferably one change of degree.Specifically, the person's handwriting width of a certain sample point can person's handwriting speed corresponding with sampled point, pressure
One or more association in force value, contact area, person's handwriting acceleration.For example, with person's handwriting speed inverse correlation, person's handwriting speed is got over
Fast person's handwriting width is smaller, and person's handwriting speed is slower, and person's handwriting width is bigger.In another example with pressure value positive correlation, the bigger person's handwriting of pressure value is wide
Degree is bigger, and the smaller person's handwriting width of pressure value is smaller.Equally, can also be with contact area positive correlation, the bigger person's handwriting of contact area is wide
Degree is bigger, and the smaller person's handwriting speed of contact area is smaller.Can also be related to person's handwriting acceleration, person's handwriting acceleration is that canonical person's handwriting is wide
Degree diminishes, and person's handwriting acceleration increases for negative then person's handwriting width.Person's handwriting width can be calculated and obtained by default function, also may be used
To be to write on corresponding data in database according to dependent variable, corresponding person's handwriting width is read according to dependent variable.Herein because become
Amount is one or more in person's handwriting speed, pressure value, contact area and person's handwriting acceleration.
Simulation vectors at S13, acquisition end points；
Simulation vectors, which are one, has the vector of size and Orientation, its direction for including simulation vectors and simulation vectors
Value.U1 represents the simulation vectors of start and end point in figure 3, and Ux represents the simulation vectors of distal point.Specifically, simulation vectors are one
The vector sent from end points, its direction is the direction that an adjacent sampled point of the end points points to the end points.
For the end points of some determination, the value of the simulation vectors of the end points and the person's handwriting width of the end points, person's handwriting degree speed,
Pressure value, contact area in person's handwriting acceleration one or more is related.Preferably, when the value and the end points of simulation vectors
Person's handwriting width it is related when, the value of the simulation vectors of the end points is inversely proportional with the person's handwriting width of the end points, and the person's handwriting of the end points is wide
The value of the more wide then simulation vectors of degree is smaller, and the value of the simulation vectors is bigger when the person's handwriting width of the end points is narrower.In emulation arrow
When amount is related to the pressure value of the end points, the value of the simulation vectors of the end points is inversely proportional with the pressure value of the end points, the pressure value
The value of the bigger simulation vectors is smaller, and the value of the smaller simulation vectors of the pressure value is then bigger.When simulation vectors and the end points
When contact area is related, the value of the simulation vectors of the end points is inversely proportional with the contact area of the end points, and contact area is more big, imitates
True vector is smaller, and the smaller then simulation vectors of contact area are bigger.
When the person's handwriting velocity correlation of value and the end points of simulation vectors, if the end points is start and end point, the start and end point it is imitative
The value of true vector is directly proportional to the person's handwriting speed of the start and end point；Or, if the end points is distal point, the simulation vectors of the distal point
Value and the person's handwriting speed of the distal point be inversely proportional.
When the value of simulation vectors and the related person's handwriting acceleration of the end points, if the end points is start and end point, the start and end point
The value of simulation vectors and the person's handwriting acceleration of the start and end point are inversely proportional；Or, if the end points is distal point, the emulation of the distal point
The value of vector is directly proportional to the person's handwriting acceleration of the distal point.
In addition, the value of the simulation vectors can also be adjacent with the end points sampled point person's handwriting width, person's handwriting degree speed, pressure
Value, contact area in person's handwriting acceleration one or more is related.
When the person's handwriting width of the value of the simulation vectors sampled point adjacent to the end points is related, the simulation vectors of the end points
The person's handwriting width of the value sampled point adjacent to the end points be directly proportional, the person's handwriting width of the adjacent sampled point of the end points is wider
Then the value of the simulation vectors is bigger, and the value of the simulation vectors is smaller when the person's handwriting width of the adjacent sampled point of the end points is narrower.
When the pressure value of the simulation vectors sampled point adjacent to the end points is related, value and the end points of the simulation vectors of the end points
The pressure value of adjacent sampled point is directly proportional, and the value of the bigger simulation vectors of pressure value of the adjacent sampled point of the end points is more
Greatly, the value of the smaller simulation vectors of pressure value of the adjacent sampled point of the end points is then smaller.When simulation vectors and the end points
When contact area is related, the value of the simulation vectors of the end points is directly proportional to the contact area of the end points, and contact area is more big, imitates
True vector is bigger, and the smaller then simulation vectors of contact area are smaller.
For example, the person's handwriting velocity correlation of adjacent sampling of the value of the simulation vectors also with the end points.The end points is origin or beginning
Point, the person's handwriting speed of the value of the simulation vectors of the start and end point sampled point adjacent with the start and end point is directly proportional；Or the end points is
Distal point, the person's handwriting speed of the value of the simulation vectors of the distal point sampled point adjacent with the distal point is inversely proportional.
In another example, the person's handwriting acceleration of the adjacent sampling of the values of the simulation vectors also with the end points is associated.That is, the emulation
The value of vector is also obtained according to the person's handwriting acceleration of the sampled point adjacent with the end points；The end points is start and end point, the start and end point
The person's handwriting acceleration of the value of the simulation vectors sampled point adjacent with the start and end point is inversely proportional；Or the end points is distal point, the end
The person's handwriting acceleration of the value of the simulation vectors of the end points sampled point adjacent with the distal point is directly proportional.
Simultaneously as the distance of the end points sampled point adjacent with its is related to this 2 points person's handwriting acceleration, therefore
When the value of simulation vectors is related to the distance, it is also assumed that 2 points of person's handwriting acceleration of the value of simulation vectors and this is related.
It is understood, of course, that ground, for the person's handwriting treatment effect specialized, is also not excluded for the value of the simulation vectors with being somebody's turn to do
One or more in the person's handwriting width of end points, contact area, pressure value are directly proportional association, i.e.,：When the value of simulation vectors is with being somebody's turn to do
When the person's handwriting width of end points is related, the value of the more wide then simulation vectors of person's handwriting width of the end points is bigger, and the person's handwriting of the end points is wide
The value of the simulation vectors is smaller when degree is narrower.When simulation vectors are related to pressure value, the bigger simulation vectors of the pressure value
Value is bigger, and the value of the smaller simulation vectors of the pressure value is then smaller.When simulation vectors are related to contact area, contact area is got over
Big then simulation vectors are bigger, the smaller then simulation vectors of contact area are smaller.
Even understandably, when the value and the person's handwriting velocity correlation of the end points of simulation vectors, if the end points is start and end point,
The value of the simulation vectors of the start and end point and the person's handwriting speed of the start and end point are inversely proportional；Or, if the end points is distal point, the end
The value of simulation vectors of point is directly proportional to the person's handwriting speed of the distal point.When the value and the person's handwriting acceleration of the end points of simulation vectors
When related, if the end points is start and end point, the value of the simulation vectors of the start and end point is directly proportional to the person's handwriting acceleration of the start and end point；Or
Person, if the end points is distal point, the value of the simulation vectors of the distal point is inversely proportional with the person's handwriting acceleration of the distal point.
It is also possible to understand, for the person's handwriting treatment effect specialized, be also not excluded for the values of the simulation vectors with
One or more in the person's handwriting width of the consecutive points of the end points, contact area, pressure value are inversely proportional association.
Specifically, i.e. when the person's handwriting width of the value of the simulation vectors sampled point adjacent to the end points is related, the end
The person's handwriting width of the value sampled point adjacent with the end points of the simulation vectors of point is inversely proportional, the adjacent sampled point of the end points
The value of the more wide then simulation vectors of person's handwriting width is bigger, and the emulation is sweared when the person's handwriting width of the adjacent sampled point of the end points is narrower
The value of amount is bigger.When the pressure value of the simulation vectors sampled point adjacent to the end points is related, the simulation vectors of the end points
The pressure value of the value sampled point adjacent with the end points is inversely proportional, bigger emulation of pressure value of the adjacent sampled point of the end points
The value of vector is smaller, and the value of the smaller simulation vectors of pressure value of the adjacent sampled point of the end points is then bigger.Work as simulation vectors
When related to the contact area of the end points, the value of the simulation vectors of the end points is inversely proportional with the contact area of the end points, contact surface
The more big then simulation vectors of product are smaller, and the smaller then simulation vectors of contact area are bigger.
In yet some other cases, during the person's handwriting velocity correlation of the adjacent sampling of the value of the simulation vectors and the end points,
If the end points is start and end point, the person's handwriting speed of the value of the simulation vectors of the start and end point sampled point adjacent with the start and end point is into anti-
Than；If the end points is distal point, the person's handwriting speed of the value of the simulation vectors of the distal point sampled point adjacent with the distal point into
Direct ratio.When the person's handwriting acceleration of adjacent sampling of the value of the simulation vectors also with the end points is associated, if the end points is start and end point,
The person's handwriting acceleration of the value of the simulation vectors of the start and end point sampled point adjacent with the start and end point is directly proportional；If the end points is end
Point, the person's handwriting acceleration of the value of the simulation vectors of the distal point sampled point adjacent with the distal point is inversely proportional.
Understandably, the value of the simulation vectors can be previously stored among default database, according to foregoing correlation
Dependent variable inquire about and obtain in database；It can also be calculated in real time by function.
When being calculated by function:
Simulation vectors U1=a*f1 (V1)+b*f2 (P1)+c*f3 (S1)+d*f4 (A4)+C, accordingly, simulation vectors Ux=a*
