2. Remote real image transmission and writing method

Hereinafter, with reference to the flowchart of FIG. 6 and FIGS. 1 and 3, an image captured by the remote real image transmission and writing apparatus 100 of the present invention is represented on the display unit 310 of the computer apparatus 300. Explain.

First, in a state in which the wireless communication module 200 is connected to the computer device 300 in the classroom, the power switch provided in the input unit 130 of the remote real image transmission and writing apparatus 100 of the invention is turned on. (ST11)

When the switch is turned on, the remote real image transmission and writing apparatus 100 enables the wireless communication unit 160 and simultaneously transmits a predetermined signal to attempt pairing with the wireless communication module 200 installed in the classroom. . A detailed pairing method will be described later. (ST12)

Pressing the camera button provided in the input unit 130 while the pairing is completed, the camera unit 110 is activated, and the image recognized by the camera unit 110 under the control of the control unit 190 through the display unit 140 Display. (ST13, ST14)

Subsequently, when the user releases the camera button, the image displayed on the display unit 140 is captured, and the data file of the captured image is stored in the storage unit 150. (ST16)

Subsequently, the wireless communication unit 160 transmits the data file stored in the storage unit 150 to the wireless communication module 200 connected to the computer device 300 under the control of the controller 190. (ST17)

The wireless communication module 200 transmits the received data file to the computer device 300, and the transmitted data file is stored in the set folder of the computer device 300. (ST18, ST19)

Subsequently, the controller 330 of the computer device 300 determines whether a dedicated program for displaying the received image data is in an activated state (ST20), and if the dedicated program is in an activated state, displays the data file as an image in the corresponding program. . Of course, the image is displayed via the display 310, (ST21)

If the dedicated program is not executed in step ST20, the controller 330 first displays the data file in the program after executing the program. (ST22, ST21)

Hereinafter, another embodiment of expressing an image captured by the remote real image transmission and writing apparatus 100 on the display unit 310 of the computer apparatus 300 will be described with reference to FIG. 7.

Since steps ST31 to ST33 of FIG. 7 are the same as steps ST11 to ST13 of FIG. 6, description thereof will be omitted.

When the user presses the camera button after the pairing is performed, the camera unit 110 is activated by the control of the controller 190, and the image recognized by the camera unit 110 is displayed on the display unit 140 and is currently displayed. The data file of the image is transmitted to the wireless communication module 200 connected to the computer device 300 in real time. (ST34)

The wireless communication module 200 transmits the received data file to the computer device 300. (ST35)

The control unit 330 of the computer device 300 determines whether a dedicated program for displaying the received image data is in an activated state (ST36). If the dedicated program is in an activated state, the controller 330 displays the data file as an image. Of course, the image is displayed through the display 310. (ST37)

If the dedicated program is not executed in step ST36, the controller 330 first displays the data file in the program after executing the program. (ST38, ST37)

Until this time, the user must keep pressing the camera button of the remote real image and writing device 100, and if the user releases the camera button, a predetermined end signal is transmitted to the computer device 300. (ST39, ST40)

The computer device 300 captures the current image as a still image after receiving the end signal, and stores the data of the captured image in a set folder. (ST41, ST42)

In order to display or write on the image while the image captured by the method of FIG. 6 or 7 is displayed on the display unit 310 of the computer device 300, the user can transmit and write the real image of the present invention. The electronic writing unit 120 needs to be activated by switching the 100 to the writing mode. Mode switching can be accomplished in several ways.

For example, in the step ST15 of FIG. 6 or the step ST39 of FIG. 7, the simplest method is to set the camera to automatically switch from the camera mode to the writing mode at the moment of releasing the camera button of the device 100. That is, whenever the user presses the camera button is switched to the camera mode, each time you release the camera button to switch to the writing mode can be used conveniently by the user.

Alternatively, the mode switching button may be installed in the input unit 130 of the apparatus 100 and set to switch from the camera mode to the writing mode and the writing mode to the camera mode each time the user presses it. (ST51)

When the user writes through the electronic writing unit 120 after the device 100 is converted to writing mode, writing data including coordinates is generated and wirelessly connected to the computer device 300 via the wireless communication unit 160. It is transmitted to the communication module 200. (ST52, ST53)

The wireless communication module 200 transmits the received writing data to the computer device 300, and the computer device 300 displays this on the display unit 310. In this case, since the captured image is already displayed on the display 310, writing data is displayed overlapping with the image. (ST54, ST55)

Meanwhile, the remote real image transmission and writing apparatus 100 of the present invention may be equipped with a text viewer program to transmit text to the computer apparatus 300. In this case, if the computer device 300 automatically executes a word program to display text data, writing may not be possible.

Therefore, when the computer device 300 receives the text data, it is preferable to convert the image data into an image file so that the user can write on the screen of the computer device 100 by using the device 100. This method is useful when describing textual material.

In the above, the method of transmitting the image data or the writing data acquired by the remote real image transmission and writing apparatus 100 of the present invention to the computer apparatus 300 and displaying them on the display 310 is described.

However, such a method may be extended to a portable electronic device having a wireless communication means, a storage means, an input means, a display means, a control means, etc., transmitting and displaying a stored file to a multimedia computer device connected to a large monitor or screen. .

For example, if the teacher selects a file stored in the portable electronic device and presses the transmit button, the file is transmitted to the multimedia computer device through wireless communication means, and the file received by the multimedia computer device is stored in a specific folder. A process of automatically executing a program for executing the file by the multimedia computer device and a process of executing the file on the program.

Alternatively, when the teacher presses the transmit button after executing the file stored in the above-described portable electronic device, transmitting data on the currently executed text, image, sound, etc. to the multimedia computer device, wherein the multimedia computer device transmits the data. A process of automatically executing a program to be executed, a process of reconstructing the received data according to the configuration of the multimedia computer device, and a process of executing the reconstructed data on the program may be continuously performed.

According to this method, the file prepared by the teacher can be transferred to the computer device with one touch and executed, thereby reducing unnecessary effort of the teacher and greatly increasing the concentration of the class.

3. Pairing method

On the other hand, in the actual classroom environment, each teacher has a remote real image transmission and writing device 100 of the present invention, the wireless communication module 200 installed in each classroom remote real image transmission and writing device 100 installed in the next classroom May receive and process signals.

In order to prevent such interference, it is preferable to use the remote real image transmission and writing device 100 after pairing with the wireless communication module 200 installed in the corresponding classroom. In particular, when using RF communication instead of directional infrared communication, the need to prevent such crosstalk is even greater. Signal processing for pairing may be performed directly by the wireless communication module 200, or may be performed by the computer device 300 receiving the signal of the wireless communication module 200, but for convenience in the wireless communication module 200 It is assumed to be performed.

Close Pairing and Multimedia Computer Power Control Method

This method is a method of pairing only when the remote real image transmission and writing apparatus 100 is in close proximity to the wireless communication module 200 or the computer apparatus 300. The remote real image transmission and writing apparatus 100 is paired for pairing. It is not necessary to register the identification code of the wireless communication module 200 or the computer device 300 in advance. This can be implemented in a variety of ways.

As a first method, the pairing signal of the remote real image transmission and writing apparatus 100 reaches only a very short distance of about 2m so that the pairing signal does not reach the wireless communication module 200 of the adjacent classroom.

On the contrary, the wireless communication module 200 may perform a pairing procedure by transmitting a pairing guidance signal within a very short distance of about 2m and recognizing an identification code from the device 100 entering this range. Limitation of signal reach can be achieved by adjusting the signal strength.

The pairing signal used in this method may be an RF signal or an optical signal (eg, an infrared signal) having linearity. The pairing signal includes an identification code assigned to the remote real image transmission and writing apparatus 100, and the identification code may be a unique number such as an electronic serial number (ESN) of a mobile phone or an ID set by a user.

The wireless communication module 200 temporarily stores the identification code included in the received pairing signal, and selects and processes only a signal transmitted from the device 100 corresponding to the stored identification code.

In this case, a separate pairing button is provided in the device 100 for the user's convenience and a predetermined pairing signal is sent when the pairing button is pressed, or a predetermined pairing signal when the power switch of the device 100 is turned on. Can be set to send automatically.

As a second method, an RFID card may be mounted on the remote real image transmission and writing apparatus 100, and the RF communication module 200 may be equipped with an RF reader for receiving a signal or obtaining information from the RFID card. The RFID card may store an identification code, and may transmit a pairing signal including the identification code. The RFID card includes an RFID chip and an antenna.

Instead of an RFID card, a magnetic tape storing an identification code may be installed, and a recognition unit capable of recognizing the identification code stored in the magnetic tape may be installed in the wireless communication module 200.

When using an RFID card or magnetic tape, since the pairing is performed only when the user contacts or approaches the device 100 with the wireless communication module 200, there is no danger of the pairing signal reaching the wireless communication module 200 of the adjacent classroom.

In this case, the wireless communication module 200 temporarily stores the identification code included in the pairing signal obtained from the RFID card or the magnetic tape, and selects and processes only the signal transmitted from the device 100 corresponding to the stored identification code.

The RFID card and the magnetic tape are intended to receive the identification code of the apparatus 100 in close proximity, and thus may be replaced by other communication means of a similar type.

When the identification code of the device 100 temporarily registered in the wireless communication module 200 through short-range pairing does not receive a signal of the device 100 within a set time (for example, 1 hour), the computer device 300 When the power is turned off, it can be set to be in a disabled state until it is deleted or a separate control signal is received.

The second device may attempt short-range pairing while the first device is temporarily registered through short-range pairing. In this case, the wireless communication module 200 may process only the signal of the second device by changing the identification code of the first device that has been temporarily registered to the identification code of the second device, and further temporarily converts the identification code of the second device. It is possible to register and process the signals of the first device and the second device equally, and additionally temporarily register the identification code of the second device only when the license of the pre-registered first device is licensed. You can also process the signal.

Specifically, the license of the first device transmits a signal for inquiring whether the wireless communication module 200 or the computer device 200 asks for permission of the first device, and the user of the first device sends the permission signal in a predetermined manner. The transmission may proceed.

This short-range pairing method may be used to control the power supply of the computer device 300. That is, when a predetermined button of the remote real image transmission and writing apparatus 100 is pressed, the power control signal is transmitted in the form of an optical signal having a linearity or an RF signal with a limited reach, thereby not affecting the computer apparatus of the adjacent classroom. Only the power supply of the computer device of the classroom can be controlled.

In addition, by recognizing the RFID card or magnetic tape mounted on the device 100 to the recognition means of the computer device 300, it is possible to control only the computer device of the classroom.

Unregistered pairing method

As another method, the identification code (eg, ID) of the remote real image transmission and writing device 100 may not be registered in the wireless communication module 200 or the computer device 300, and may be registered in advance and paired using the same. It may be.

In the former case, that is, in the non-registered pairing method, when the remote real image transmission and writing apparatus 100 is switched on and transmits a predetermined pairing signal in an RF method, the wireless communication module 200 receives the pairing signal. The identification code of the device included in the pairing signal is temporarily registered, and after that, only the signal corresponding to the registered identification code is processed.

This method permits temporary registration for only one device, and the registered identification code is stored only until the next user pairs or until the computer is turned off.

In addition, a non-registered pairing method for temporarily allowing a plurality of devices is also possible. For example, if the pairing signal is received from the second device while the first device is unregistered, additionally temporarily registers the identification code of the second device and processes the signals of the second device and the first device equally, The wireless communication module 200 or the computer device 200 sets the second device only when the user of the first device is licensed by setting the connected first device as a main device and setting the second connected device as a slave device. It can also process the signal from the device.

In one embodiment of the temporary registration, one or more pairing list that can register the identification code of the one or more remote real image transmission and writing device 100 to the wireless communication module 200 or the computer device 300 After setting, the identification code of the device 100 requesting pairing can be temporarily registered in the pairing list.

In this case, the wireless communication module 200 or the computer device 300 may process only the signal of the device 100 registered in the pairing list, and when the pairing is released, the identification code of the corresponding device 100 may be deleted from the pairing list. . The unpairing requirement may be set when the computer device 300 is powered off, when a predetermined unpairing signal is received from the device 100, when no signal is received from the device 100 for a set time, or the like. have.

Registration pairing method

This method registers an identification code of one or more remote real image transmission and writing apparatus 100 to be used for the wireless communication module 200 or the computer device 300. This is a method of pairing in a state registered in advance.

When the registered device 100 is used, the wireless communication module 200 or the computer device 300 may determine whether the received signal includes an identification code of the registered device and process only a signal including the same. At this time, there is only one registration list, and there is an existing method of permanently using only one device and registering a plurality of devices of the same type so that a plurality of devices can be used.

When a plurality of identification codes are registered in the wireless communication module 200 or the computer device 300, there is a method of using the computer device 300 by pairing with one device 100 by another instructor entering a class every time. .

In addition, when two or more instructors enter the class, feedback should be made between the instructor and the student, or have a meeting, two or more devices 100 may be used.

In this case, the wireless communication module 200 or the computer device 300 simultaneously activates the pairing of the first device and the second device to process the signals of the first device and the second device equally, or first connect the first device. It is also possible to activate the second device as a slave device and to process the signal of the second device only when the first device is activated and the user of the first device is licensed. In addition, when the slave device is paired with the master device tries to pair, the slave device may be unpaired and paired with the slave device.

In addition, a signal of a third non-registered device may be accepted and used. In order to process the signal, pairing with a third device must be temporarily performed. Therefore, the wireless communication module 200 extracts an identification code included in a signal of the third device. Alternatively, the computer device 300 may be temporarily registered.

Temporary registration means that if the device's signal is not received within the set time (for example, 1 hour), the computer ID 300 is turned off, or another user sends a pairing request signal, It means that it is set to be in an inactive state until it is deleted or a separate control signal is received.

The wireless communication module 200 or the computer device 300 may further include the aforementioned pairing list in addition to the registration list.

In this case, it is first determined whether the identification code of the device 100 requesting pairing is registered in the registration list, and only when the identification code is confirmed to be registered, the identification code of the device 100 is recorded in the pairing list. Activate pairing with device 100. When pairing is released, pairing is inactivated by deleting only the identification code of the corresponding device 100 recorded in the pairing list.

Pairing method linked with work schedule such as class schedule

Most educational institutions have time schedules organized by period, so it is necessary to automate the multimedia class time of each classroom for more effective instruction.

If the multimedia training using the computer device 300 provided in the classroom, the remote real image transmission and the identification code of the writing device 100 to be used in the multimedia education and stored in conjunction with the class schedule time required for class preparation It can shorten and increase the convenience of teachers.

Specifically, as shown in the flowchart of FIG. 7, the class timetable, the remote real image transmission, and the identification code of the writing device 100 are interlocked and stored in the computer device 300 provided in the classroom. (ST71) In the state where the information is stored, the teacher turns on the remote real image transmission and writing apparatus 100. (ST72)

At this time, the computer device 300 determines whether the identification code included in the signal received from the remote real image transmission and writing apparatus 100 matches the identification code corresponding to the current class time. (ST73)

If the result of the determination is matched, pairing is performed, and then the computer device 300 automatically executes the multimedia program required for the corresponding class time and displays it on the main screen or edits it in a menu form and displays it on the display 310. In addition, necessary content may be searched for and displayed on the display 310. (ST74)

According to this method, the teacher does not need to operate the computer device 300 to execute the necessary multimedia program or to search the contents, so that the teacher or student can quickly concentrate on the class.

In addition, according to this method, since the computer device 300 pairs with the device 100 having the identification code corresponding to the corresponding class time, there is no need to consider confusion with other devices located in the adjacent classroom.

If the class time is changed or the teacher is replaced by changing the class timetable and the identification code of the device stored in the computer device 300, such a change is to be made in the central server connected to the computer device 300 of each classroom It is preferable.

The method described above is not necessarily limited to the import timetable and can be applied to various types of work schedules.

In the above described the pairing method of the remote real image transmission and writing apparatus 100 of the present invention. However, the method may be applied to a case in which a portable electronic device having a wireless communication means, a storage means, an input means, etc. is paired with a multimedia computer device connected to a large monitor or a screen and a presentation is used.
