Description

Electronic blackboard having many function

The present invention relates to a multifunctional electronic blackboard, and more particularly, when a personal computer and an electronic blackboard are opened in both directions and written on an electronic blackboard through a pen mouse, the contents are displayed on the personal computer and stored in real time and need to be written. On the contrary, the invention relates to a multifunctional electronic blackboard in which the contents of a personal computer can be displayed on the electronic blackboard through a projector.

As is well known, general lecture methods are written in the form of chalk on the blackboard while lecturers take lectures, and they are written by the learners and applied to most schools, academies, and conferences. In addition to the need for double work to be erased, the board is not used while erasing the board, which can lead to inefficiency, dust, adversely affecting your health, and relying on your memory for the inconveniences and lectures you need to take. There are many problems for lecturers and students.

In light of this, electronic boards using touch boards and electronic pens have recently emerged to enable writing or one-touch clearing through electronic pens, providing convenience to lecturers, while scanning files written on the blackboard through scanning. It provides convenience to the students by converting it into a printout or storing it on a personal computer. However, this is a simple electronic writing method that cannot satisfy all users. It is demanding.

The present invention has been devised in view of this point, and the electronic blackboard and the personal computer can be opened in both directions, and the contents of the electronic blackboard can be stored in the personal computer in real time through a projector between the personal computer and the electronic blackboard. In addition to the contents stored in the personal computer can be displayed by projecting on the electronic blackboard through the projector, various colors can be displayed to the outside according to the movement path of the pen mouse to create a multi-functional electronic blackboard that can be added at any time The purpose is to provide.

In another aspect, the object of the present invention is to increase the effectiveness of the lecture by enabling the lecturer's voice to be stored on a personal computer in the form of a compressed file so that it can be reproduced and reproduced later.

Hereinafter, the present invention will be described in detail according to the present embodiment.

In the multifunctional electronic blackboard according to the present invention, an infrared sensor 2 and an ultrasonic sensor 3, 3 'are mounted on a frame 1 as shown in FIGS. 1 and 2, and the front surface serves as a screen or a display panel. A personal computer connected to the copyboard 5 via a whiteboard panel 4 having a white sheet panel 4 and a cable 6 bidirectionally branched to open in both directions with the copyboard 5. (7), a projector (9) connected to the personal computer (7) and optionally a cable (8) to project the image of the personal computer (7) onto the seat panel (4) of the copyboard (5), and the copyboard In contact with the seat panel 4 of (5), the infrared sensor 2 and the ultrasonic sensor 3 (3 ') operate to determine its position, and based on the information, an application program embedded in the personal computer 7. Drive to display lines of various colors to the outside of the seat panel (4). A button that can be controlled by the ram consists of a pen mouse 10 that cheomsak the displayed information, the electronic board (5).

At this time, since the sheet panel 4 must display various colors, a fluorescent film having an appropriate pixel must be formed therein, and the fluorescent film is preferably configured like a liquid crystal screen due to the shape characteristic of the electronic blackboard 5.

In addition, the surface of the sheet panel 4 should have a light transmittance enough to be displayed to the outside when the phosphor inside the light is emitted, as well as have a reflectance enough to act as a screen when the projector 9 is operated. It is configured as, the surface is processed so that writing is possible with a general aqueous pen.

The multifunctional electronic blackboard according to the present invention configured as described above may be divided into a projector mode and a real time mode. In the projector mode, the pen mouse 10, the projector 9, the personal computer 7, and the electronic board 5 Various images are displayed in combination, and in the real time mode, the pen is written on the surface of the copyboard 5 with an aqueous pen (not shown) like the pen mouse 10 or the white board.

First, in the projector mode, the screen of the personal computer 7 is projected onto the seat panel 4 by the projector 9, and the seat panel 4 serves as a screen, of course, the seat panel ( 4) This function does not only serve as a screen, but can be performed directly on the copyboard 5 by using the pen mouse 10 to perform all the programs used in the personal computer 7 on the copyboard 5. Clicking, right-clicking, numeric input, and character input are possible, and important parts can be underlined or corrected on the projected contents through the projector 9.

In addition, since the contents of the lecture are displayed as it is on the personal computer 7, it is possible to save in real time as a desired picture file, and with the contents of the lecture, the voice of the lecturer can be stored as a compressed file by using a separate device, thereby creating a vivid image. The contents of the lecture can be reproduced with the training of the lecturer to double the effect of the lecture, and can be provided to those who did not attend the lecture to achieve the same effect as the actual lecture.

The real time mode differs from the projector mode in that the image information stored in the personal computer 7 cannot be displayed on the copyboard 5 without using the projector 9, except that the same is different from the projector mode. As well as appearing on the screen of the personal computer (7), the contents are stored in the form of picture files in the personal computer (7) in real time, the stored files can be sent by e-mail or stored on the server can be downloaded or played by others as well as lectures The sound of the contents is saved as a compressed file and can be played. At this time, the biggest feature of the real-time mode is that it is possible to write on the surface of the copyboard 5 with a general water-based pen instead of the pen mouse 10. Even when writing with a general water-based pen, the contents of the screen of the personal computer 7 can be used. You can save it in the form of a file, and the lecturer can later erase it with an eraser for the whiteboard.

Meanwhile, in performing the projector mode and the real-time mode described above, the most important thing is that various colors are displayed in a linear form when the pen mouse 10 is brought into contact with the seat panel 4, which is illustrated in FIG. 3. When the pen mouse 10 is brought into contact with the seat panel 4 as described above, the infrared rays transmitted from the pen mouse 10 are detected by the infrared sensor 2, and then the two upper and lower ultrasonic sensors 3 and 3 ′ are operated to operate the pen mouse 10. Ultrasonic waves transmitted from the sensor are detected, and the time t1 and t2 measured from the infrared detection to the respective ultrasonic detection are converted into data and sent to the personal computer 7, and input through an application program embedded in the personal computer 7. The position of the pen mouse 10 can be accurately determined by calculating the data, and when the position of the pen mouse 10 is determined by an application program, the phosphor inside the sheet panel 4 emits light. As to form a line with a desired color according to a movement path of the pen mouse 10, the display, by a simple structure with fewer components would be for accurate localization.

As described above, in the present invention, the electronic blackboard and the personal computer are opened in both directions so that the contents of the personal computer can be displayed on the electronic blackboard through the projector, and the contents displayed on the electronic blackboard are again displayed on the screen of the personal computer. Appears and can be saved in real time, the content can be corrected through the pen mouse, the lecturer can perform the lecture without the need for chalk, the learner will not need the writing, the voice of the lecturer will be stored in a compressed file form Afterwards, the lecture contents can be reproduced and viewed along with the vivid training of the lecturer, and the contents can be provided to those who did not listen to the lecture.
