Automatic transition method between window-mode and writing- mode for electric blackboard}

The present invention relates to a method of automatically switching between the window mode and the writing mode of the copyboard, and more specifically, it is possible to directly write on a window when a specific condition is satisfied, so that the writing mode and the window mode are inconvenient from the user's point of view. The present invention relates to a method of automatically switching between a window mode and a writing mode of the copyboard to automatically switch modes to increase convenience and increase the use efficiency of the copyboard.

Recently, the multimedia integrated teaching system using the electronic blackboard, which is introduced as a part of the construction of a high-quality digital education environment for the training of professionals in each university and company, has been spreading. As a result, manipulating equipment for instructor preparation is becoming more complicated and the difficulty is increasing.

Therefore, there is a need to reduce the fear of the multimedia integrated teaching system that enables various multimedia equipment installed in the classroom to be operated by a single switch in consideration of the user's convenience, and to enable efficient lecture preparation.

Such a general multimedia integrated teaching system 30 installed in a lecture room or conference room, which is generally used, and using an electronic blackboard is configured as shown in FIG. 1.

That is, a cassette deck unit 2 capable of driving a cassette tape recorder inside one case 20, an image deck unit 3 driving a video device such as a DVD or a VTR, and a microphone 8 are provided. Amplifier unit 1 for amplifying the audio signal output from the instructor's voice and cassette deck unit 2, video deck unit 3 and output through speaker 10, keyboard 5, mouse 6 or Pen mouse 6a (hereinafter collectively referred to as 'mouse 6' and '6a'), and an electronic blackboard 9 capable of displaying various types of information and writing with the mouse 6 and 6a, and includes various information and applications. The above-described apparatus (cassette deck section 2, video deck section 3, amplifier section 1, computer section 4) by operating the built-in computer section 4 and the lecturer's auxiliary keypad 7. The control unit 13 is provided to collectively control the system, such as switching the output mode and on / off control.

In addition, on the upper surface of the case 20, the electronic blackboard (9) capable of displaying various images and character information transmitted from the image deck unit (3) and the computer unit (4) and writing with a mouse (6) 6a; The lecturer easily controls the output mode of the cassette deck unit 2, the image deck unit 3, the amplifier unit 1, and the computer unit 4, and the control unit 13 for switching the on / off control writing / window mode. Auxiliary keypad 7 which can be controlled so as to be controlled, and a microphone 8 which converts the instructor's voice into an electrical signal and transmits it to the amplifier unit 1 are exposed to the outside.

And a projector 12 for displaying various image data output from the image deck unit 3 and the computer unit 4 on the large screen 11.

Referring to the general operation of the multimedia integrated teaching system 30 configured as described above and the operation of the writing mode as follows.

First, the general operation of the multimedia integrated teaching system 30 using the electronic blackboard is made as follows. That is, when power is supplied to all the devices, the system is in a state capable of operating, while the computer unit 4 is booted to be in the initial state of the window mode, and the initial screen of the window mode is copied on the copyboard 9 The display is displayed on the screen 11 through the projector 12 at the same time.

In this state, when the instructor loads the lecture data stored in the computer unit 4 for the lecture, as described above, the lecture image and text data are displayed on the electronic blackboard 9 and the screen 11 is displayed through the projector 12. ) Will be displayed.

At this time, if the lecturer wants to lecture using the image data recorded on the DVD and VTR, if the specific key of the auxiliary keypad 7 is selectively operated, the control unit 13 recognizes this and the image deck unit 3 The output medium of the DVD or VTR is controlled, and the image data output from the DVD / VTR is displayed on the screen 11 through the projector 12, and at the same time, the image is displayed on the copyboard 9.

In addition, when a lecturer intends to lecture using voice data recorded on a cassette tape by a lecturer's intention, if a specific key of the auxiliary keypad 7 is selectively operated, the controller 13 recognizes this and then the cassette deck unit 2 Will control the output.

And, as described above, by manipulating the auxiliary keypad 7 according to the instructor's intention, the cassette deck unit 2, the image deck unit 3, and the computer unit 4 simultaneously designate any one or two and output the data. When a medium to be selected is selected, the audio signal recorded on the selected medium is amplified by the amplifier unit 1 and transmitted through the speaker 10.

The above has described the outline of the operation of the multimedia integrated teaching system 30, and includes a number of other functions, but as a general matter can not be a major factor for the subject matter of the present invention and a detailed description thereof will be omitted.

Next, the process of switching between the conventional writing mode and the window mode in using the copyboard 9 as related to the gist of the present invention will be described with reference to the flowchart of FIG. 2.

First, when the user executes a writing program to write on the electronic blackboard with a pen mouse (step 101), the computer recognizes this and executes the writing program (step 101).

When the writing program is executed, it is determined whether or not to switch to writing mode (step 102). In order to switch to writing mode, after capturing a screen to be written (step 103), the writing is possible. If necessary, the writing mode is executed (step 105) while the writing color is selected (step 104), and the user continues writing on the target screen. If you want to write on another screen by the user's selection, you have to switch screen (step 106) and to switch to window mode (step 107), move the target screen (step 108) and write again. Screen capture (step 103) allows writing on another target screen.

In the conventional copyboard, which is operated as described above, the writing mode has a problem of capturing and writing the writing target screen (step 103). Therefore, when writing on the screen of the target 1 and then trying to write on the screen of another target 2 Whenever the screen moves, a repetitive phenomenon that requires repeated capturing of the screen (step 103) occurs, and the user must go through a confusing process, thereby degrading the quality of the lecture and reducing the user's desire to use the screen. It has caused the phenomenon.

In other words, the conventional writing application cannot directly write on the window, and since writing has to be performed on an image object (for example, a bitmap), the window and the writing application have been independently called.

This is because, because the window itself is displayed on the screen as the drawing method using the window context, the external application preempts the control of the window director context when writing directly on the window. A conflict occurred between Windows and the corresponding application. For this reason, writing on a computer blackboard was difficult because writing on a specific screen, for example, an image or an object on a specific screen, was difficult. .

In other words, due to the nature of the window system, the window system gives each application its own DC to express its own program, and each program can be drawn only in its own director context. Before writing, it was possible to write after copying the display information of the screen into the context of its own director through screen capture.

For example, when writing on the World Wide Web screen, you can bring up the web screen, capture the screen as an image, then write it, and if you want to scroll again, enter window mode, then scroll the screen to capture the screen and write it again. Because of the inconvenience of having to repeatedly move between the window mode and the writing mode, it is impossible to mix the window and the writing application program. Therefore, the efficiency and reliability of the lecture are lowered due to the problem of direct computer blackboard lectures using Windows. There is a problem.

In order to solve the above problems, the window system manages a screen director context in addition to managing a director context of an application that is running. When the screen director context is directly accessed, a director of another application is used. It is based on the principle that the desired writing can be made in the context.

In other words, the present invention is to determine whether the mouse click state and the moving distance in the click state of the mouse when the currently determined mode is the window mode in the computer unit including a solution for driving the electronic blackboard And if the moving distance is over a certain range, the writing mode is automatically executed, and if the mouse's click holding time and the moving distance are less than a certain range, the writing mode is automatically recognized as a click state and automatically switched to the normal window mode, allowing direct writing on the window. As the direct lecture using the window mode is possible, the mode is automatically switched without the inconvenience of the writing mode and the window mode from the user's point of view, thereby increasing the convenience of the lecturer and increasing the efficiency of using the copyboard. It is a technical problem.

The present invention is provided with an electronic board capable of writing, and a computer unit with a built-in program for writing on the electronic board. The current mode is a window mode by determining whether the current state is a window mode in the computer unit. If it is determined that the window mode execution process for executing the window mode, the click state determination process for determining whether the mouse is in a click state in contact with the electronic blackboard when the window mode execution process, and the mouse clicks in the click state determination process If it is determined that the state is determined to calculate the time from the click time to the position change occurs, if the time is less than a predetermined time, the time calculation process for performing the window mode execution process, and the calculation time is constant in the time operation process If it is over the range, the movement distance is calculated by clicking the mouse. If it is less than a certain range, the distance operation process for performing the window mode execution process, if it is determined that the value calculated in the time operation process and the distance operation process is all over a certain range, the writing mode execution process for executing the writing mode, and the writing mode If it is determined that the mouse is separated from the copyboard during the execution process, the writing mode is terminated and an unclick determination process for executing the window mode is characterized in that it is made.

Hereinafter, a process of automatically switching between the window mode and the writing mode of the copyboard according to the present invention will be described in detail with reference to FIG. 3.

First, as shown in FIG. 3, the computer unit determines whether the current state is the window mode (step 201), and if it is determined that the current mode is the window mode, executes the window mode (step 202). Will be performed.

Then, while performing the window mode execution process (L1), the user performs a click state determination process (L2) for determining whether the pen mouse is in a click state in contact with the electronic blackboard, and the click state determination process (L2). If it is determined that the state is in the click state, the time from the click state until the position change occurs, that is, the time from the click state to the movement is calculated (step 204), and the calculated time is determined to be equal to or less than a predetermined time (step 205). If it is simply recognized as a click state to execute the time operation process (L3) to maintain the window mode.

After the time calculation process L3, the computer unit calculates the movement distance (step 206) when it is determined in step 205 that the time from the click state to the time when the position change occurs is a predetermined time or more. If it is determined that the moving distance of the pen mouse is less than a predetermined distance (step 207), it simply recognizes that it is in a click state and performs a distance calculation process (L4) for maintaining a normal window mode (step 202). If it is determined in step 207 of L3) that the distance value of the pen mouse is moved to a predetermined range or more, it recognizes that the writing mode is finally performed and executes the writing mode execution process L5 that switches to the writing mode.

The process of calculating the moving distance of the pen by the computer unit when the distance calculation process L4 is executed is as follows.

Typically, when the electronic pen touches the writing monitor, the window generates a Mouse Down message, which receives the current pen position as a parameter value.

When the electronic pen is moved, the window generates a number of mouse move messages, which also take the current pen position as a parameter.

Therefore, when the mouse down message occurs, the position value that is transferred to the argument value is stored in the memory part. When the next incoming mouse movement message occurs, the position value that is transferred to the argument value together when the mouse down message has occurred before The distance of the pen is calculated by comparing with the saved position value.

If it is recognized that the pen mouse is an unclick to be separated from the copyboard in the state where the writing mode execution process L5 is in progress (step 209), the computer unit determines that the writing is finished and ends the writing mode (step 210). By performing an unclick determination process (L6) of switching to the original window mode, a series of processes of automatically switching the window / writing mode are completed.

In step 204 of the time calculation process (L3), the reason for calculating the time from the click state to the movement of the mouse first is that if the user's intention is simply a click, there will be no displacement in the state where the pen mouse is clicked. If the user's intention is in the writing, it must move in the click state to determine if the user is simply clicking or writing. This range of time is typically considered to be very short. have.

In addition, the reason why the mouse moves secondly in the click state in step 206 of the distance calculation process L4 is that the user's intention is simply a click state in the process of step 204, whereas the click state is fixed for a predetermined time due to a mistake. This is to prevent an error that may occur immediately if you keep it in writing mode.

In other words, if the user's intention is writing, it must be moved in order to display characters, lines, and shapes in the click state, and thus the moving distance is constant in the click state to determine whether the user's intention is click or writing. Secondary determination is whether it is above the range.

Therefore, the precision of the user's intention is improved by recognizing that the conditions of the steps 204 and 206, that is, the time from the click state to the movement and the moving distance in the click state must satisfy certain conditions.

As described above, the present invention automatically switches between the window and the writing application program according to the operation state of the mouse, and the process operation of the general Windows operating system and the writing application of the writing application program in the window mode while the writing application program is executed. The combined functionality allows writing directly on the window while sharing the screen director context with other applications while the writing application is running, and by immediately disabling writing on the screen director context when a typical mouse event occurs. By using the window function at the same time, it is possible to solve the conflict between the window and the writing application, and to write directly using the window mode.

Therefore, the present invention can be written in window mode or in writing mode by analyzing the click time of the mouse and the moving distance in the clicked state without additional work such as the user operating the copyboard with the minimum command execution and clicking a separate button. By automatically switching from mode to window mode, user convenience and application width can be expanded.

In addition, the present invention can be applied to a multimedia integrated teaching system, as well as an electronic blackboard of a white board, a tablet monitor, a lecture room or a conference room in a ubiquitous environment, and the scope of application thereof is not limited.

As described above, according to the present invention, when the currently determined mode in the computer unit for driving the electronic board is the window mode, the mouse click and hold time and the movement distance are determined by determining whether the mouse is clicked and the moving distance in the clicked state. If the distance is over a certain range, the writing mode is automatically executed.If the mouse's click holding time and the moving distance are less than a certain range, the writing mode is automatically recognized as a click state and automatically switched to the normal window mode. As the direct lecture using the mode is possible, the user can automatically switch the mode without inconvenient switching between writing mode and window mode from the user's point of view, improving user convenience, increasing the use efficiency of the copyboard, and widening the application range. It is effective.
