When the digital luminous point is shown as mark luminous point, demonstrator can control the mark by the handheld device
Luminous point is mobile, and according to the coordinate of mark luminous point on image superposition layer real-time rendering marking line.The type of marking line is optional, no
Same type uses different method for drafting.For example, a kind of marking line type is trajectory line, according to the motion track of mark luminous point
Generate marking line；Another seed type is straight line, then determines marking line according to the initial coordinate of mark luminous point and changing coordinates；It is another
Seed type is circle (or oval), then to mark the initial coordinate of luminous point as the center of circle, in terms of the distance of changing coordinates and initial coordinate
The radius (or elliptical major radius and short radius are calculated with preset length-width ratio) of circle is calculated to determine marking line；There are also a seed types
It is rectangle, then marking line as two of rectangle is determined to angular vertex using the initial coordinate and changing coordinates that mark luminous point.
In step S204, when the release for receiving first key instructs or stops touching instruction, described in completion
The marking line of drafting is simultaneously retained on described image superimposed layer by the drafting of marking line.
When the first key of demonstrator's Continued depression or sustained touch and the position of mobile mark luminous point, and move
To the marking line of desired drafting terminal when, demonstrator can unclamp the first key, or stop touching the first key, examine
When measuring the release instruction of first key or stopping touching instruction, then the drafting of marking line is completed.
The mode of sampling pressing or sustained touch draws marking line, it is only necessary to pass through a pressing operation of a key
The drafting in the marking line of image superposition layer can be completed, it is possible to reduce the effect of jitter as brought by button operation, favorably
In the convenience for improving operation.
Mode two triggers marking line drafting by pressing instruction or click commands, as shown in Figure 3, comprising:
In step S301, the pressing instruction or click commands of first key are received；
Marking line described in Fig. 3 draws mode, is the triggering for drawing mode with marking line described in Fig. 2, terminates mode phase
A kind of mode of difference.The one-touch process of mechanical key includes that pressing starts, Continued depression and pressing terminate three phases,
The primary touch process of membrane keyboard includes that touch starts, sustained touch and touch terminate.When detect first key by
It presses off the beginning or touches i.e. triggering pressing instruction when starting, touched at the end of the pressing for detecting first key terminates or touches
Send out click commands.
In step s 302, when receiving the pressing instruction or click commands, if the mode of the number luminous point is not
It is dimension model, then the mode that the digital luminous point is arranged is dimension model, shows mark luminous point on a display screen；
It is receiving pressing instruction or is further including judging the mode of digital luminous point when click commands, according to working as
The difference of premode triggers different command contents.For example, present mode can be dimension model or non-dimension model.If
Present mode is not dimension model, and since the first key is mark key, the function of triggering is marking Function, the mould of digital luminous point
Formula enters dimension model, shows mark luminous point on a display screen.
It is mobile according to the mobile control of the handheld device mark luminous point in step S303, according to the mark
The movement of luminous point draws marking line on described image superimposed layer；
When the mode of digital luminous point is mark luminous point, according to preset marking line type, such as trajectory line, straight line, circle, ellipse
Round or rectangle etc., and the coordinate of mark luminous point draw marking line on image superposition layer.
In step s 304, when receiving the pressing instruction or click commands of first key, if the number
The mode of luminous point is dimension model, then completes the drafting of the marking line and the marking line of drafting is retained in described image superposition
On layer.
After mark cursor is moved to specified position and confirms that marking line meets the requirements, user triggers pressing instruction again
Perhaps click commands detect that the mode of pressing instruction or click commands and digital luminous point is dimension model at this time, then terminate
The drafting of the marking line determines the final position of marking line according to pressing instruction or the position of click commands.
Both the above mode, by a key can meet marking line drafting requirement, do not need multiple keys it
Between toggle, be conducive to mention high control precision.
In step s 103, after completing the drafting of the marking line, the size of the marking line is calculated, by the mark
The size of line is compared with preset first threshold；
After the drafting for completing marking line, there may be the maloperation of demonstrator, the marking line drawn is too small, at this time
A mark point or a bit of marking line are shown in image superposition layer, is made troubles to the explanation of demonstrator, also to later
Deletion makes troubles.In order to solve this problem, the size of marking line is compared with preset first threshold in this step,
Determine the mark point for being less than first threshold or mark line segment.
The size of the marking line can there are many definition mode, for example, the length of marking line can be defined as, for
The closing such as circle/ellipse/rectangle marking line can be defined as the area that marking line surrounds, can also be according to the default mark of marking line
Region is defined, for example, default tab area long side its area or its can include a preset shape region
Deng.
The tab area of herein described marking line is used to identify the effective coverage of marking line, and digital luminous point is in marking line
Tab area in when the marking line can be operated.Tab area is typically larger than marking line itself, by for marking line
One tab area bigger than marking line itself is set, subsequent deletion or selection operation can be made more convenient.Marking line
After completing, if the size of marking line will be calculated according to the tab area of marking line, the calculating of tab area is used
Method obtains the default tab area of the marking line, and the size of marking line is calculated with the default tab area.Marking line it is default
Tab area and the final tab area of marking line may be different, because if default tab area is too small, need to optimize and revise
In favor of the subsequent operation for marking line.
When the size of marking line is compared with first threshold in the application, may include the comparison of length, the comparison of area,
It can be the comparison of region characteristic, correspondingly, first threshold can be length threshold, area threshold or preset shape
Region etc., wherein the region of preset shape can be minimum operation area.Since hand shake will lead to speaker to digital light
The control precision of point position is limited, therefore for too small region, is difficult to accurately enter with handheld device and completes to operate.This
Minimum operation area definition is that speaker can be moved by the digital luminous point of handheld device control and be readily achieved operation in application
Minimum Area.The shape in minimum operation area can be set as the square of a default side length or the circle of pre-set radius.Cause
And the size of marking line compared with first threshold when, can be the length of marking line or the length of its default tab area and pre-
If length threshold comparison, or the area of area or its default tab area that marking line surrounds and preset area
Threshold value comparison, or can also be compared for the default tab area of marking line with the region of preset shape, for example, judgement mark
Whether the default tab area for infusing line can include minimum operation area.
There are many calculation methods for the default tab area of marking line in the application.For example, when the type of marking line is straight line
When, if the line style of marking line is wider, default tab area can be marking line itself, and otherwise, default tab area is set as marking
Note line itself extends out the region of a circuit covering；When marking line can surround a closed area, as marking line type be circle,
Oval, rectangle or trajectory line (two points of head and the tail of trajectory line are connected and to form a closed area) etc., the default mark of marking line
Note region can be set to the closed area；The default tab area of marking line can also be for around a rectangle of the marking line
Region, the rectangular area can be the minimum rectangular area comprising the marking line, or include the marked figure of the marking line
One extended area of shape object, for example, the entire text block that the extended area can be marked by marking line.
In step S104, if the size of the marking line be less than the first threshold, delete the marking line or
For the marking line, the tab area that one energy includes preset minimum operation area is set.
If the size of the marking line is less than preset first threshold, it may be considered that the marking line belongs to maloperation
Marking line can choose and directly delete the marking line, so that the marking line for avoiding maloperation from generating is shown in image superposition layer；Or
Person still leaves the power to make decision for deleting marking line for speaker, and still, when marking line is too small, default tab area cannot include
When minimum operation area, speaker is difficult to choose the marking line and delete, and it includes pre- for needing to be arranged for the marking line energy
If minimum operation area tab area.It is described to be defined as tab area comprising the tab area in preset minimum operation area
Inside can be embedded at least one preset minimum operation area.
A kind of feasible method that the tab area that an energy includes preset minimum operation area is arranged is: with default marked area
Toward external expansion centered on domain, until it can include minimum operation area.Since the difference of the default tab area pattern is (such as thick
Carefully) or the difference of stripe shape, the pattern and size of the default tab area also can be different, include an energy is arranged
When the tab area in preset minimum operation area, corresponding extended mode can be selected according to the pattern or shape of marking line.Than
Such as, it when generating the tab area of hachure, can be extended in the width direction of hachure, determine point marking line or ringlet
When the default tab area of marking line, then can put or ringlet centered on be extended, thus generate can comprising it is preset most
The tab area of small operating space.
The embodiment of the present application increases image superposition layer on Presentation Graphics interface, in the key command for receiving the first key
When, image superposition layer draw marking line calculate the size of marking line after drawing marking line, by the size of marking line with
Preset first threshold compares, and if it is less than the first threshold, then deletes the marking line, or be arranged one for the marking line
It can include the tab area in preset minimum operation area.Due to drawing marking line on an increased image superposition layer,
The data that can be played for any software adds marking line.In addition, the key command by the first key can be directly in image superposition
Layer draws marking line, can simplify labeling operation；And when the size of marking line is less than first threshold, then directly delete mark
Line, or the tab area that one energy includes preset minimum operation area is set for the marking line, so that delete operation is more simple
It is convenient.
In order to advanced optimize as mark control method described herein, after completing marking line drafting, digital luminous point
Mode can be switched to indicating mode, or hidden state can also be switched to.
In order to advanced optimize mark control method described herein, if digital luminous point is instruction luminous point, and indicate
When luminous point is in the tab area of existing marking line, different display samples can be used to the marking line where instruction luminous point
