Time writer is a kind of device that can generate electromagnetic wave, is contacted in time writer with electronic plane (for example, writing process
In) when, electromagnetic wave (electromagnetic touch signal) that the touching box equipment in electronic plane is sent by receiving time writer can calculate
Go out the position (touching position information) that time writer contacts with electronic plane, the electromagnetism that different time writers can be sent in the application
Wave frequency section is different, for example, 1024 grades of time writer A pre-given electromagnetic frequency is 120KHz-140KHz, 1024 grades of time writer B's is pre-
If electromagnetic frequency is 150KHz-170KHz, although the dynamics pressed during writing may be identical, the electromagnetic wave of time writer A generations
All the time in the range of 120KHz-140KHz, the electromagnetic wave of time writer B generations is in the range of 150KHz-170KHz all the time, from
And the electromagnetic wave can be distinguished according to the scope residing for the electromagnetic wave of reception to be sent by which branch time writer, touching box equipment exists
After going out pressure sensitivity information according to electromagnetic touch signal of change, to being expanded according to default expansion algorithm pressure sensitivity information, make not
Pressure sensitivity information with time writer has a different forms, that is, the pressure sensitivity information after expanding have from different time writers corresponding to preset
The pressure sensitivity information of form；By taking 1024 grades of time writers as an example, pressure sensitivity is 0~1023 integer, carries out simple classification to numeral at present
Mode have a singulative and even number form, fixed mantissa form etc., for example, when distinguishing 2 time writers, can by 1,3,
5 ... wait odd number to wait even number to expand as another time writer using 0,2,4 ... as the pressure sensitivity information after a time writer expansion
Pressure sensitivity information after filling；Or the pressure sensitivity information after can a time writer be expanded becomes mantissa and is all 0, by another electromagnetism
Pressure sensitivity information after pen expansion becomes mantissa and is all 1 etc..Down-stream is available for according to pressure sensitivity data separation electromagnetism by expanding
Pen.
Step S130：By the pressure sensitivity Information encapsulation after touching position information, expansion into multiple point touching signal, to the multiple spot
Touch signal is parsed, wherein the pressure sensitivity information after expanding is resolvable to floating type；
The common form of multiple point touching signal is (X, Y, Down, Up, Move), and (X, Y) represents the coordinate position touched,
Down, Up, Move describe touch action and press, lift, sliding these three states respectively, and the application is by the pressure sensitivity information after expansion
Also it is encapsulated into multiple point touching signal, for example, sending multiple point touching letter in the form of (X, Y, Pressure, Down, Up, Move)
Number, wherein (Pressure) represents pressure sensitivity.The multiple point touching signal of outside input, which will be sent to operating system, can just be employed journey
Sequence is received, and operating system can be parsed to multiple point touching signal to identify information therein, wherein the pressure sensitivity after expanding
Information is resolvable to the floating number between floating type, such as 0.0~1.0.
Step S140：Floating type pressure sensitivity information is converted into by the pressure sensitivity information after expanding, root according to default transfer algorithm
It is the default writing attribute information of time writer according to the pressure sensitivity information matches after expansion, has in the touch location generation of time writer pre-
If write the handwriting trace of attribute.
Exemplified by pressure sensitivity information in the form of foregoing singulative and even number, 100 and 101 change into floating number after will be difficult to area
Point, therefore, floating type pressure sensitivity information is converted into the pressure sensitivity information after expanding, Ji Jiangfu by the application according to default transfer algorithm
The form of pressure sensitivity information of the point-type pressure sensitivity information reverting to after expanding, so as to which this is more according to the pressure sensitivity data separation after expansion
Where touch signal removes time writer if belonging to, can be that different time writers presets different writing attribute informations, such as an electricity
Magnetic pen is arranged to a red, another time writer and is arranged to blueness, so as to write category according to the pressure sensitivity information matches after expansion
Property information, be red in the handwriting trace of handwriting trace of the touch location generation with corresponding writing attribute, such as a time writer
Color, the handwriting trace of another time writer are blueness.It is different although traditional approach can also change the writing attribute of time writer
The writing attribute of time writer be identical, constantly to change writing attribute if wanting to write out different colours, and more people book simultaneously
The written contents of each writer are still cannot distinguish between when writing, and the application can be the different color of different time writers settings, line
Shape etc. writes attribute, when branched time writer is write simultaneously, different colours, linear handwriting trace can be generated, so as to distinguish
Go out written contents corresponding to each writer, can also be used different time writers as " crayon ", eliminate frequently modification book
The problem of writing attribute.
Above talk about according to the pressure sensitivity information after the expansion with presets to distinguish different time writers, connect
Get off to introduce and how to obtain singulative and even number form, the pressure sensitivity information after the expansion of fixed mantissa form.
Time writer is bifurcated come area for the pressure sensitivity information by singulative and even number form, then default transfer algorithm
Can be：
Pressure sensitivity value in one time writer pressure sensitivity information is expanded according to formula (1)；
Pressure sensitivity value in another time writer pressure sensitivity information is expanded according to formula (2)；
Fa1=2 × Fa0+1……(1)
Fb1=2 × Fb0……(2)
Wherein：Fa0、Fa1Pressure sensitivity value before and after expanding for a time writer in pressure sensitivity information, Fb0、Fb1For another time writer
Pressure sensitivity value before and after expansion in pressure sensitivity information.
The pressure sensitivity value obtained after being expanded by above-mentioned formula (1) is odd number, is expanded by above-mentioned formula (2)
The pressure sensitivity value obtained afterwards is even number.As shown in Fig. 2 write with 1024 grades of time writer A, time writer B in electronic plane 200
Exemplified by, if pressure sensitivity value corresponding to writing is 100, pass through formula (1)：2 × 100+1=201, time writer A pressure sensitivity value expand
Fill into 201, passed through formula (2)：2 × 100=200, time writer B pressure sensitivity value have been expanded into 200, so as to pass through pressure sensitivity
Value is that singulative or even number form distinguish touch signal caused by time writer.
By the parsing of operating system, it is minimum that the pressure sensitivity information of above-mentioned singulative and even number form becomes difference
Floating type pressure sensitivity information, it is as caused by any branch time writer, by floating-point to enable applications to distinguish multiple point touching signal
The pressure sensitivity value of type is converted into the pressure sensitivity value after expanding according to formula (3)；
F=INT (f × (2 × u-1)+0.5) ... (3)
Wherein：F is the pressure sensitivity value of time writer floating type, and F is the pressure sensitivity value after expanding, and u is the pressure sensitivity of default time writer
Grade, INT are rounding operation.
For example, the pressure sensitivity value 200 after expanding is changed into after the floating types of 8 digits as 0.09765625, the pressure sensitivity after expansion
Value 201 is 0.09814453 after changing into the floating type of 8 digits, for 1024 grades of time writer, is counted according to formula (3)
Calculate：INT (0.09765625 × (2 × 1024-1)+0.5)=200, INT (0.09814453 × (2 × 1024-1)+0.5)=
201, wherein increase by 0.5 value can offset because changing into floating type during be related to round up cause reduce when round
The numerical bias that computing occurs, thus the pressure sensitivity value that the pressure sensitivity value of floating type can be accurately reverted to after expanding.Pass through again
Which branch time writer is the multiple point touching information for the odd even of pressure sensitivity value judging that reception can be distinguished belong to, so as to application program according to
Corresponding to writing attribute generation handwriting trace.For example, teacher on electronic plane with blueness time writer set a question " 1+1=" please
Student is gone forward to answer, and student is answered questions in writing out " 2 " with the electromagnetism of blueness, and teacher can draw " √ " with the time writer of red or "×" is entered
Line flag, written contents corresponding to each writer can easily be distinguished by different colors.
No more than ten time writers are distinguished for the pressure sensitivity information by fixed mantissa form, then default transfer algorithm
Can be：
Pressure sensitivity value in time writer pressure sensitivity information is expanded according to formula (4)；
Fn1=10 × Fn0+n……(4)
Wherein：Fn0、Fn1Pressure sensitivity value before and after expanding for (n+1)th time writer in pressure sensitivity information, n 0,1 ..., in 9
Any integer.
The pressure sensitivity value of same branch time writer can obtain the pressure with fixed mantissa after being expanded by above-mentioned formula (4)
Inductance value, by the 1st of 1024 grades the to the 10th time writer exemplified by electronic plane is write, if pressure sensitivity value corresponding to writing is
100, then pass through formula (4)：10 × 100+0=1000, the pressure sensitivity value of the 1st time writer have been expanded into 1000, have passed through formula
(4)：10 × 100+1=1001, the pressure sensitivity value of the 2nd time writer have been expanded into 1001, pass through formula (4)：10 × 100+9=
The pressure sensitivity value of 1009, the 10th time writer has been expanded into 1009, and pressure sensitivity value is according to formula (4) caused by same branch time writer writing
Mantissa after expansion is identical, so as to be believed by mantissa's form of the pressure sensitivity value after expansion to distinguish to touch caused by time writer
Number.
By the parsing of operating system, the above-mentioned pressure sensitivity information with fixed mantissa form becomes and can not directly recognized
Floating type pressure sensitivity information, in order to enable applications to distinguish multiple point touching signal be as caused by any branch time writer, will be floating
The pressure sensitivity value of point-type is converted into the pressure sensitivity value after expanding according to formula (5)；
Fn=INT (fn×(2×vn-1)+0.5)……(5)
Wherein：fnFor the pressure sensitivity value of (n+1)th time writer floating type, FnFor the pressure sensitivity value after expansion, vnFor default electromagnetism
The pressure sensitivity grade of pen, INT is rounding operation.
For example, the pressure sensitivity value 1000 after expanding is changed into after the floating types of 8 digits as 0.09765625, the pressure sensitivity after expansion
Value 2000 is 0.1953125 after changing into the floating type of 8 digits, for 1024 grades of time writer, is counted according to formula (5)
Calculate：INT (0.09765625 × (2 × 1024-1)+0.5)=1000, wherein the value of increase by 0.5 can be offset because changing into floating-point
The numerical bias that rounding operation occurs when causing reduction that rounds up being related to during type, thus can be by the pressure of floating type
The pressure sensitivity value that inductance value is accurately reverted to after expanding.Again by judging that the odd even of pressure sensitivity value the multiple point touching of reception can be distinguished
Which branch time writer is information belong to, so as to which application program is according to corresponding writing attribute generation handwriting trace.
In time writer writing process, different pressure sensitivity is produced according to the difference of writer's dynamics, so as to realize basis
Writing physical strength changes the line style thickness of handwriting trace, shade etc., realizes the sensation as truly write on paper using writing brush
(" former person's handwriting " is write).Although the application for distinguish time writer and pressure sensitivity value is expanded, expand after pressure sensitivity value with
Former pressure sensitivity value is proportional example, thus, it is possible to adjust line style thickness, the color of handwriting trace according to the pressure sensitivity information after expansion
The depth.For example, when bifurcating time writer by the pressure sensitivity information of singulative and even number form come area, can be by the pressure after expansion
Inductance value 0,1 is corresponding with line style thickness, shade corresponding to 0 of pressure sensitivity value before expansion, by the pressure sensitivity value 2,3 after expansion with expanding
Line style thickness, shade are corresponding corresponding to the 1 of pressure sensitivity value before filling；Distinguished not by the pressure sensitivity information of fixed mantissa form
During more than ten time writers, can by the pressure sensitivity value 0 after expansion, 1 ..., 9 with expand before pressure sensitivity value 0 corresponding line style it is thick
Carefully, shade is corresponding, by the pressure sensitivity value 10 after expansion, 11 ..., 19 with expand before pressure sensitivity value 1 corresponding line style it is thick
Carefully, shade is corresponding.So as to when distinguishing the written contents of each time writer, moreover it is possible to realize that " former person's handwriting " is write.
As a rule, for electronic plane configuration differentiable time writer quantity be it is limited, certainly, the number of time writer
Amount is also limited, can not possibly be that each color sets a time writer substantially, need exist to providing modification writing for time writer
The function of attribute, 2 kinds presented below exemplary modification modes：
Pressure sensitivity after detecting the configuration information modified to writing attribute and triggering the expansion of the configuration information is believed
During breath, by amended writing attribute information and the pressure sensitivity information association after the expansion；
When the configuration information that the time writer writing attribute detected to entitled A is modified, by amended writing
Attribute information and the pressure sensitivity information association after time writer expansion；
Wherein, writing attribute includes：Line style, color, font, identifier.
As shown in figure 3, user modifies in electronic plane 300 to time writer to writing attribute, amended writing
Attribute information associates with triggering the time writer of the configuration information, i.e., is currently which branch time writer writes attribute information, table in modification
Show it is that writing attribute to this branch time writer is modified, in time writer operating process, according to its caused electromagnetic touch signal
It is which branch time writer is operating that can distinguish, so as to write attribute information and the pressure sensitivity information after the expansion by amended
Association.The modification mode is directly convenient, still, as time writer quantity more (such as 10), to change 10 time writers
Modification writing attribute information one by one, the operating burden of user can be increased, therefore, as shown in figure 4, the application also proposed according to pen
The mode that name is modified, user modifies in electronic plane 400 to time writer to writing attribute, i.e., to certain branch time writer
Writing attribute information modify, the time writer just has an amended writing attribute, and modification mode is convenient and intuitive.
Corresponding with the embodiment of foregoing more time writer writing differentiating methods, present invention also provides more time writers to write area
The embodiment of separating device.
Fig. 5 is refer to, more time writer writing discriminating devices 500 include：
