INFINITE MARKING EXECUTION SYSTEM OF MARKING PROGEAM FOR ELECTRONIC BOARD AND EXECUTING METHOD THEREOF}

The present invention relates to a writing screen operation of a writing program for an electronic blackboard which can be installed and operated in a computer system. More specifically, the writing screen is generated by generating position coordinates of two or more points simultaneously on the writing screen. To move the writing screen area indefinitely while moving to the right (hereinafter referred to as " infinite writing " collectively referred to herein as allowing the writing screen area to be moved indefinitely without the maximum width and maximum height which can be moved); The present invention relates to an infinite board execution system and an execution method of an electronic board writing program.

Generally, a writing board program for an electronic board refers to software developed so that an input device receives an input signal of an electronic board device, not a keyboard or a mouse, and writes it on a computer.

Unlike the actual writing tools such as white board or blackboard, these writing programs can add various functions using software technology. In particular, there is a technique of moving the writing screen upward, downward, leftward, or rightward, which is one of the functions that can be added to the writing screen area of the writing writing program.

If the user can move the writing screen to the top, bottom, left, and right, the user using the writing program can continuously perform the writing operation by moving the writing screen without erasing the written screen.

Usually, such a moving function of the writing screen is performed by a touch screen and a touch screen, as shown in Korean Patent No. 10-2007248-0000 ("automatic conversion of electronic board and white board and multi- A screen shortcut key for switching the display device screen to a signboard screen is formed on one side of the basic screen of the combined display device. If a separate signup is required during presentation or meeting, the display device screen is entirely changed to a signboard screen A program for moving the screen to a scroll bar (see reference numeral 110 in FIG. 1) as an example of a document creating program or an Internet searcher capable of scrolling the screen, , It is general that the screen is used for the purpose of moving a screen area of a certain size.

Therefore, if the width and height of the movable paneler screen area are fixed, the following restrictions arise.

First, if the width and height of the movable boarder screen are short, the function of moving the boarder screen is greatly reduced in utilization, and in the case where the width and height are long, the operation of moving the boarder screen to the scroll bar may be inconvenient.

Second, in order to implement the technique of moving the panel screen area up, down, left, and right, there is a need to consider a panel screen so that a user using the panel programming program can move the panel screen area up, down, left, There is a problem that a technique for implementing a user interface so as to be operable and a technique for implementing a screen to be movable are required.

Accordingly, an object of the present invention is to solve the above problems, in the implementation of the function to implement the writing screen to move indefinitely without limiting the maximum movable width and height of the writing screen area. The user who uses the writing program can use the infinite writing function and the infinite writing function so that users who use the writing program can continue the writing operation naturally without having to be aware of the upper, lower, left, and right sides of the writing screen area. It is to provide an infinite writing execution system and execution method of the writing program for the electronic blackboard that can easily manipulate the movement of the writing screen.

The infinite writing execution system of the writing program for an electronic blackboard according to the present invention includes a touch signal generated when a user touches a writing screen with an object such as a finger or an electronic pen, and the user makes contact with the writing screen. The writing screen displayed by a touch program generated by a touch input signal such as a touch move signal generated when a user moves the object from the writing screen and a touch input signal generated when the user touches the object on the writing screen. and; A touch input signal analyzer for counting the number of the touch input signals generated on the writing screen and analyzing the type of the touch input signals; A formatter screen movement mode on / off flag for recognizing whether the touch move signal is a form filler operation or a form filler screen move operation; A touch input signal number recording unit for recording the number of the touch input signals counted by the touch input signal analyzing unit; It is characterized by consisting of the writing screen movement and the writing operation execution unit operated by the touch signal, the touch move signal, and the touch-up signal.

In addition, the infinite writing method of the writing program for an electronic blackboard according to the present invention comprises the steps of generating a touch signal on the writing screen; When the touch signal is generated, adding 1 to the number recorded in the touch input signal number recording unit in the touch input signal analyzing unit; Wherein the touch input signal analyzing unit determines whether the number recorded in the touch input signal number recording unit is two or more; If the number recorded in the touch input signal number recording unit is less than 2, the touch input signal analyzing unit determines that the touch input operation is a touch input operation and executes a touch input operation; If the number recorded in the number of touch input signal counts is greater than or equal to 2, determining a boarder screen moving mode and turning on a boarder screen moving mode on / off flag; Generating a touch move signal; Arithmetically computing a distance traveled by the touch move signal; Canceling the writing operation; The ink data starting to move by the arithmetic operation; Determining whether all of the ink data have been moved; If all of the ink data has not been moved, the ink data is continuously moved to complete the movement of the writing screen.

It is a flowchart for explanation.

As shown in FIGS. 2 to 6, the infinite blackboard execution system 200 for the electronic blackboard according to the present invention includes a writing screen 210, a touch input signal analysis unit 220, and a writing screen moving mode on / off. / Off) flag 221, the touch input signal number recording unit 230, and the writing screen movement and writing operation execution unit 240.

Here, a touch signal is generated when a user touches an object such as a finger or an electronic pen on the writing screen 210 on the writing screen 210, and the user touches the object on the writing screen 210. A touch move signal is generated when moving in a contact state, and a touch up signal is generated when the user touches the object on the writing screen 210. The touch signal, the touch move signal, and the touch up signal are touch input signals, and the writing board program for the electronic blackboard is operated by the touch input signal, while the user is writing on the writing screen 210, the touch signal or A touch move signal is generated and a touch-up signal is generated when the user finishes writing and floats an object on the writing screen 210.

When the touch signal is generated to count the number of the touch input signals, the touch input signal analyzing unit 220 adds 1 to the numbers recorded in the touch input signal number recording unit 230, When the touch-up signal is generated, subtracts 1 from the number recorded in the number-of-touch-input-signal-recording unit 230 and records the number in the number-of-touch-input-signal recording unit 230. For example, when the touch panel 210 is touched to generate a touch signal, the touch input signal number recording unit 230 records 1, and when a touch up signal is generated, the touch input signal number recording unit 230 0 " is recorded.

Also, the writing screen moving mode on / off flag 221 is turned on / off by the touch input signal analyzing unit 220.

The touch input signal number recording unit 230 records the number of touch input signals such as a touch signal and a touch up signal generated in the formatter screen 210. In the initialization process, Is set to the number 0.

Accordingly, by checking the number of touch input signals recorded in the number-of-touch-input-signal-recording unit 230 added and subtracted by the touch input signal analyzing unit 220, The number of objects can be grasped.

The form panel screen movement and writing operation executing section 240 includes a touch panel operation executing section 241, a touch move panel operation executing section 242, a touch up panel operation executing section 243, 244, respectively, and executes the touch panel operation, the touch move panel operation, and the touch up panel operation according to the generation of the touch signal, the touch move signal, and the touch up signal,

The touch input signal analyzing unit 220 determines whether the touch move signal is a writing operation or a writing operation according to whether the number of touch input signals recorded in the number of touch input signal recording unit 230 is 2 or more or 2 or less. It is configured to determine whether or not it is a screen movement operation.

Accordingly, when the touch move signal is generated, the touch input signal analyzing unit 220 turns on the writing screen moving mode on / off flag 221, and the touch input signal analyzing unit 220 Determine the number of input signals. If the number of touch input signals recorded in the number-of-touch-input-signal-recording unit 230 is two or more, the touch input signal analyzing unit 220 recognizes the touch input signal as a pan screen moving operation, ) To execute the movement of the edition screen. If the number of touch input signals recorded in the number-of-touch-input-signal-recording unit 230 is less than 2, the touch input signal analyzing unit 220 recognizes the number of touch input signals as a pen writing operation, To execute the writing operation.

Now, let's look at the infinite writing method of the copyboard program according to the present invention.

First, before describing a processing procedure for a touch input signal generated in the writing form screen 210, a composition of writing form data for the infinite writing form function will be described.

Line data such as text or picture that the user writes on the writing screen 210 is processed and stored as vector data for position values on the X and Y coordinates of the writing screen 210 (hereinafter, the position values on the coordinates are " Collectively referred to as "ink data".

This ink data is advantageous in that the line 510 is managed by the list form 510 of the respective point coordinates 400 so that the upward, downward, leftward and rightward movement can be easily implemented through arithmetic operation.

Therefore, the infinite writing execution system and the execution method of the writing program for the electronic blackboard do not display ink data on the writing screen 210 having a fixed size to implement the infinite writing function. Only the writing board screen 210 is configured to display vector coordinates in accordance with the display device resolution.

The movement process of the writing screen 210 is processed by the movement 420 of the ink data. That is, in the present invention, the writing screen 210 does not move, but moves the ink data so that the user looks as if the writing screen 210 is moved.

The core of the infinite formatter function according to the present invention can be obtained by processing the movement effect to the structure of such ink data and movement 420 of the ink data, not the writer screen 210.

The vector data, the ink data processed by the arithmetic operation related to the movement, and the moving method of the writing screen 210 may be classified into a writing operation which is a process of generating new vector data in accordance with a touch input signal generated in the writing screen 210, And the operation of moving the planer screen 210, which is an arithmetic operation process of the ink data.

Hereinafter, an infinite writing method of the writing program for an electronic blackboard according to the present invention will be described.

First, the touch input signal will be described as follows.

In general, a touch input signal generated by a user using an object such as a finger or an electronic pen on the writing screen 210 may include a touch signal generated when the writing screen 210 contacts an object such as a finger or an electronic pen. There is a touch move signal generated when moving in a contact state and a touch up signal generated when a finger or an object is touched. In particular, in the present invention, a touch move signal is generated by touching two fingers or objects. The touch input signal analyzer 220 determines the signal as a writing screen moving operation to move the writing screen 210.

For the touch input signal analyzing unit 220, the writer program is initialized at the start of the program.

In the program initialization process executed at the start of the programmer program, the number of touch input signal number recording unit 230 for recording the number of touch input signals is set to 0, and the programmer screen movement mode on / off flag 221 is set to false .

Here, the touch input signal analysis unit 220 records the number in the touch input signal number recording unit 230 when an object such as a finger or an electronic pen contacts or detaches the writing screen 210. When it occurs, 1 is added to the number recorded in the touch input signal number recording unit 230, and when the touch-up signal is generated, 1 is subtracted from the number recorded in the touch input signal number recording unit 230.

Then, the touch input signal analyzing unit 220 determines whether the number stored in the number-of-touch input signal storage unit 230 is equal to or greater than 2. This means that the touch input signal analyzing unit 220 is initialized at the start of the writing program, If the number recording unit 230 has a value of 2 or more, it means that the touch signal has occurred twice or more, which indicates that two or more fingers or an object has contacted the touch screen 210.

When two or more values are written in the number-of-touch-input-signal-recording unit 230, the touch input signal analyzing unit 220 changes the writing mode shift-on / off flag 221 to a true value and the process is completed. In other words, if a value less than 2 is written in the number-of-touch-input-signal-writing unit 230, the touch input signal analyzing unit 220 for a typical writing function Let the touch-making process proceed.

As described above, when a touch-up signal is generated, the touch input signal analyzing unit 220 subtracts 1 from the number recorded in the touch input signal number writing unit 230. [ Thereafter, the writer screen movement mode on / off flag 221 is confirmed. This is to complete the writing screen moving operation if the state when the touch-up signal is generated is in the writing mode screen moving mode.

If the state when the touch-up signal is generated is in the booklet screen moving mode, the touch input signal analyzing unit 220 sets a false value in the writing screen moving mode on / off flag 221 Up signal is generated, the touch input signal analyzing unit 220 analyzes the touch-up boarder operation executing unit 243 to perform a normal writing function. So that the touch-up signing process proceeds.

Accordingly, when a touch move signal is generated on the touch screen 210, the touch input signal analyzing unit 220 first checks the value of the pen slide shift mode on / off flag 221, The flag is set to be the same as the value of the formuler screen moving mode on / off flag 221. In other words, if the value of the writer screen moving mode on / off flag 221 is a false value, The touch input signal analyzing unit 220 causes the touch move preparation unit 242 to proceed with the touch move preparation process.

Now, referring to FIG. 7, the flow of the infinite writing method of the writing program for the electronic blackboard will be described.

First, a touch signal is generated on the touch screen 210 (S711).

Thereafter, the touch input signal analyzing unit 220 adds 1 to the number recorded in the touch input signal number writing unit 230 (S712).

Thereafter, the touch input signal analyzing unit 220 determines whether the number recorded in the number-of-touch input signal register 230 is two or more (S713).

If the number stored in the number-of-touch-input-signal-recording unit 230 is less than 2, the touch input signal analyzing unit 220 determines that the touch input operation is performed, (S714). If the number recorded in the number-of-touch-input-signal-recording unit 230 is 2 or more, it is determined that the pen writing mode shift mode is selected and the pen writing mode shift on / ). At this time, the touch move signal includes the moved distance data, and the moved distance data is a necessary value when the ink data to be described later is to be moved.

Thereafter, when the touch move signal is generated (S716), the distance of the touch move signal is arithmetically operated (S717). At this time, the arithmetic operation distance is stored in the writer screen movement execution unit 244.

Thereafter, the writing operation is canceled (S718). At this time, the cancellation of the writing operation is performed by deleting the unnecessary ink data because the ink data generated in the touch input signal is discriminated as the writing screen moving operation, not the writing operation.

Thereafter, the ink data starts moving by the arithmetic operation (S719). At this time, all the text or pictures existing in the form of the list 510 of ink data displayed on the formatter screen 210 should be recalculated in order based on the arithmetic operated distance.

Thereafter, it is determined whether all the ink data have been moved (S720).

If all the ink data are not moved, the ink data is continuously moved (S721). If all of the ink data is moved, the writing screen moving is completed.

By the above process, the movement of the writing board screen is ended.

As described above, the infinite blackboard execution system and the execution method of the present invention are the electronic blackboard apparatus and writing program to both the teacher and the student during the course using the electronic blackboard device due to the simple operation and visually simplified infinite blackboard expression effect Helps you focus on the class without being conscious of it.

Although, in the embodiment of the present invention, the writing screen is moved using the fingers of the user's two hands, the present invention is not limited thereto, and the user can move the writing screen using two or more fingers of one hand. Of course.

In addition, in the embodiment of the present invention, the writer screen movement mode on / off flag is integrated in the touch input signal analyzing unit and the touch input signal number recording unit is not integrated. However, The writing mode shift mode on / off flag and the number of touch input signal number recording units may be integrated or not integrated.
