Wherein, mapping parameters can be configured by user in mapping parameters configured board, can also be adopted
With the mapping parameters value of acquiescence.
The mapping of motion track is actually the mapping of the position coordinates of each contact on motion track, that is, is worked as
When capturing the contact on screen, according to the scaling in default mapping parameters, by contact in screen
On position coordinates mapping obtain the position coordinates of dummy contact, finally constituted by each dummy contact above-mentioned
Virtual track.That is, having obtained track to the mapping of track by the mapping one by one put.
, can be by the position coordinates of current contact, contact on screen on screen in the mapping put
The initial position (position coordinates of first contact of i.e. true motion track) of motion track, determine
The coordinate and scaling of the initial position of virtual track, obtain the dummy contact that current contact is mapped to
Position coordinates.Equation below (1) and formula (2) can specifically be used：
X_vi=X_v0+ (X_ri-X_r0) * m (1)
Y_vi=Y_v0+ (Y_ri-Y_r0) * m (2)
Wherein, X_v0 and Y_v0 is the coordinate of the initial position of virtual track, and X_r0 and Y_r0 are true
Motion track first contact position coordinates, X_ri and Y_ri are i-th of real motion track
Position coordinates of the contact on screen, X_vi and Y_vi are the dummy contact that above-mentioned i-th of contact point mappings are obtained
Position coordinates, i is integer more than 1, and m is scaling.A contact is often captured on screen,
Above-mentioned mapping is carried out, each dummy contact is just obtained, the contact track just with user writing on screen shows
Virtual track according to certain scaling is shown.Meanwhile, with the motion track of the contact of user writing,
The motion track of the contact of user writing, i.e., real contact track can also be shown simultaneously on screen.
If user stops writing, the touch operation of screen is not captured more than preset duration, then terminate when previous
The display of section virtual track, goes to step 101 and starts to determine the determination of the initial position of next section of virtual track,
And the writing of next section of virtual track.In addition, do not capture the touch operation of screen more than preset duration,
The display of motion track of the contact on screen can also be removed, that is, removes the display of real contact track,
To facilitate user to prepare next section of writing on screen.
With reference to embodiment illustrated in fig. 2 exemplified by being write on the touchscreen with finger, to the above method
It is described in detail, as shown in Figure 2, this method can specifically include following steps：
In 201, mapping parameters are determined after startup.
After startup, it is first determined mapping parameters.In this step, the mapping of system default can be joined
Number is defined as mapping parameters used in follow-up writing.It can also will preserve the mapping parameters of user's the last time
Set, the last mapping parameters of user are provided as mapping parameters used in follow-up writing.Also may be used
To provide a user mapping parameters configured board, the mapping that user is set by mapping parameters configured board is obtained
Parameter, and it is used as mapping parameters used in follow-up writing.
It should be noted that in addition to determining mapping parameters when application starts, for user in follow-up book
When carrying out the setting of mapping parameters by mapping parameters configured board during writing, setting according to user again is understood
Put determination mapping parameters.
In 202, the touch operation on screen is caught, if capturing multiple point touching operation on screen,
Then perform 203；If capturing single-touch operation on screen, 205 are performed.
In 203, station-keeping mode is switched to.
In the present embodiment, the switching of station-keeping mode and write mode can have multiple point touching to operate and single-point
Touch operation is triggered, i.e., when capturing multiple point touching operation, such as user carries out double refer on screen
Movement, then switch to station-keeping mode.If capture single-touch operation, for example user is in screen
The upper movement singly referred to, then switch to write mode.
Except of course that outside with multiple point touching and single-touch triggering switching, other modes can also be used,
The mode of the function button of the pattern switching of such as offer on click screen.For PC, also may be used
To click on screen using such as click right mouse button, by some button on lower keyboard or by mouse
Mode of function button of pattern switching of upper offer, etc..
In 204, the position coordinates of last contact captured under station-keeping mode is defined as virtually
The initial position of track.
In a positioning mode, user's specifying to the initial position of virtual track is mainly realized.Due to fixed
Under bit pattern, user repeatedly can carry out multiple point touching to change the initial position of virtual track, Zhi Daoman
Meaning position, therefore can be virtual by the position coordinates seat of last contact captured under station-keeping mode
The initial position of track.
Assuming that user initially opens writing when applying, the interface showed as shown in fig. 3a, of the invention real
Apply in example, the position of dummy contact can be indicated all the time using a form of a stroke or a combination of strokes icon, first shown in Fig. 3 a
In beginning interface, form of a stroke or a combination of strokes icon can be placed in the position of an acquiescence, for example, be placed in certain of the screen upper left corner
Individual position.It is if user does not change the position of form of a stroke or a combination of strokes icon, the position where form of a stroke or a combination of strokes icon nib is straight
Connect the initial position as virtual track.If user wants the initial position that oneself specifies virtual track,
Then double refer to it can touch and move on screen, the position finally lifted is as the initial of virtual track
Position, as shown in figure 3b.
In 205, write mode is switched to.
In 206, under write mode, with the movement of the contact on screen, the movement of contact is shown
Track, motion track of the contact on screen is mapped, obtained according to default mapping parameters from first
The beginning virtual track that starts of position simultaneously shows the virtual track on screen.
Under write mode, one section of continuous writing operation mainly includes the processing of three parts：
1) motion track of contact is shown, that is, the real trace that display user's finger is moved.
Shown that used color and line style can also be advance by user for the motion track of contact
Configured, it would however also be possible to employ the color of acquiescence and linear.In addition, if the motion track of display contact
It can also be configured, user can select to show the motion track of contact, can also select not showing tactile
The motion track of point.
2) motion track of the contact on screen is mapped according to default mapping parameters, obtain from
The virtual track that initial position starts.
The mapping of motion track is actually the mapping of the position coordinates of each contact on motion track, that is, is worked as
When capturing the contact on screen, according to the scaling in default mapping parameters, by contact in screen
On position coordinates mapping obtain the position coordinates of dummy contact, finally constituted by each dummy contact above-mentioned
Virtual track.When carrying out the mapping of each point, above-mentioned formula (1) and formula (2) can be used.
It should be noted that the monitoring for touch operation on screen is performed by operating system, if
Touch operation occurs on screen, then operating system can be listened to include in touch event, touch event and touched
Point information, such as contact position, touch type etc..Operating system can be by the touch thing listened to simultaneously
Part is supplied to application layer, is used for concrete application.
3) virtual track is shown.
It is each virtual tactile after the position coordinates mapping for carrying out each contact obtains the position coordinates of each dummy contact
Point constitutes virtual track, can be according to the color in mapping parameters when being shown to virtual track
The style information such as information and/or line style information, shows virtual track.
The order that the processing of the part of the above three is not strict is limited, it is preferable that for the contact captured,
The processing of the part of the above three can be performed simultaneously.
Hookup 3a and Fig. 3 b example, if user carries out single-touch, such as Fig. 3 c on screen
Shown in, then write mode is switched to, while the point of first touch is contact motion track on screen
Initial position, be designated as (X_r0, Y_r0).User starts the point of this first touch as starting point
One section of continuous writing, as shown in Figure 3 d, writes " 1234 " on screen in the way of single-touch,
Then show the motion track of contact on screen, and can be as the movement of contact is by the position of each contact
Mapped according to the scaling in mapping parameters, obtain the virtual track of each dummy contact.In display
Can be using pattern parameters such as color, the line styles in mapping parameters during virtual track.In addition, on screen
Form of a stroke or a combination of strokes icon can be moved with the position of dummy contact so that be appeared on screen by pen
The virtual track that shape icon is write out, one is convenient more vivid, interesting, on the other hand, can also facilitate
User knows the current position of dummy contact, and dummy contact is targetedly carried out during so as to follow-up writing
Initial position fix.
In 207, if it exceeds preset duration does not capture touch operation, then contact is removed on screen
Motion track display.
Preset duration in this step can also can be matched somebody with somebody using the value given tacit consent to, such as 1s by user
Put.Example shown in hookup 3d, if user writes " 1234 " stops writing afterwards, finger frames out.
Touch operation is not captured more than 1s, then removes the display of motion track of the contact on screen, such as scheme
Shown in 3e.
In addition, under write mode, user can also at any time, by clicking on what is provided on interface
The mode of cls function button removes the display of motion track of the contact on screen.
In 208, touched next contact position coordinate captured as first of next section of writing
The position of point, and it is virtual using the location updating of last dummy contact of obtained virtual track
The initial position of track.
The example continued shown in 3e, if user is after one section of continuous writing is terminated, it is desirable to proceed book
Write, then need to carry out the initial position of virtual track during next section of writing.Following three kinds can so be used
Mode：
First way：Station-keeping mode is switched to using multi-touch screen, in a positioning mode to virtual
The initial position of track is positioned.
The second way：Pattern switching need not be carried out, is remained under write mode, user estimates next
The initial position of virtual track, then determines first on screen by the way of single-touch during section writing
The position of individual contact, while the location updating of last dummy contact of obtained virtual track is empty
Intend the initial position of track.
As shown in Fig. 3 f, a position is estimated in user's range estimation, clicks on the position so that the position is under
The position of first contact of one section of writing, i.e., the original position of next section writing.The position is clicked in user
While putting, with the position of last dummy contact of current virtual track, (i.e. current virtual nib is indicated
Position) be used as next section writing virtual track initial position.During actual program, exist
The parameter of the initial position of one virtual track, after this step, with this step map obtain it is virtual
The position coordinates of contact updates the initial position parameters of virtual track.
Then user just can then carry out next section continuously near the position clicked on above
Writing, as shown in fig. 3g, writes since first contact, is reflected while also being proceeded by from the contact
Penetrate generation virtual track.Assuming that user continuously writes " 567 ", as shown in figure 3, perform can be with for this part
Go to execution 206.
The third mode：Pattern switching need not be carried out, still under write mode, directly utilizes and obtains
The initial position of the location updating virtual track of last dummy contact of the virtual track arrived, it is same with this
When, the position of first contact of next section of writing is indicated on screen.User is only needed to from instruction
Start next section of writing near the position of first contact.The process is compared with second method, no
