Description

[Technical field]

[0001] The present invention relates to an integrated electronic whiteboard system and a method for constructing the same, and more specifically, to an integrated electronic whiteboard system that can realize the GIGA School Concept and is constructed on an existing whiteboard, and a method for constructing the integrated electronic whiteboard system that can construct the integrated electronic whiteboard system simply, quickly and at low cost. [Background technology]

[0002] Following the announcement of the GIGA School Initiative implementation package in 2019, schools have established in-school LANs and are rapidly introducing and utilizing ICT in schools. The core of the GIGA School Initiative is to create an educational ICT environment that is personalized for each child and student and fosters creativity. Specifically, it creates an environment in which each child and student is given a learning device (tablet) and lessons are conducted using electronic whiteboards installed in each classroom.

[0003] However, blackboards are installed in each classroom in schools, and lessons in schools have long been conducted based on writing on the blackboard, which is a teaching method familiar to both students and teachers, and is difficult to abandon suddenly, even if ICT education advances. Furthermore, introducing large electronic blackboards to replace conventional blackboards in each classroom is extremely difficult from a budgetary standpoint, and is unrealistic.

[0004] For these reasons, it has been thought of and put into practical use to use existing blackboards or whiteboards, place a projector on top of the board and project images onto the board to turn the board into an electronic blackboard (interactive board) (Patent Publication No. 2021-128299, Patent Publication No. 2018-189925).

[0005] However, it is difficult to project clearly on a blackboard, and replacing a blackboard requires a great deal of effort and cost, and in particular, the construction period and time are limited, making it extremely difficult to carry out work on many schools in a short period of time (usually, replacing a blackboard takes five workers half a day per classroom). Furthermore, these systems do not anticipate the use of electronic blackboards, the functionality of which has been rapidly improving in recent years, and are not in line with the times.

[0020] The present invention will be described in detail with reference to the accompanying drawings. The term "existing blackboard" as used herein refers to a large existing blackboard or whiteboard installed in a school classroom or the like, and is not limited to a flat board, but also includes curved boards or semi-curved boards (the example shown in the figure is an existing curved blackboard).

[0021] The method for constructing a multi-functional electronic whiteboard system according to the present invention is a method for constructing a multi-functional electronic whiteboard system that can realize the GIGA School Project by utilizing a large existing whiteboard installed in a school classroom or the like. The first embodiment of the method is as follows: - a step of installing an electronic whiteboard on one end side surface of the existing whiteboard; - a step of disposing a screen unit on the other end surface of the existing blackboard so that the screen can be pulled out laterally; -The method includes a step of installing a projector that is linked to the electronic whiteboard in a mirroring manner above the existing whiteboard.

[0022] The composite electronic whiteboard system according to the first embodiment of the present invention is constructed by the above method, and is configured such that the electronic whiteboard 2 is fixedly installed at one end of the existing whiteboard 1, the screen unit 3 is arranged at the other end, and the projector 4 that is mirror-linked with the electronic whiteboard 2 is installed above the middle part. The electronic whiteboard 2 can be easily installed on the surface of the existing whiteboard 1 by using a commercially available wall-mounting bracket for televisions. The projector 4 is installed via a projector arm (not shown) fixed to the upper frame of the existing whiteboard 1 or the wall surface above it. When the existing whiteboard 1 is a curved board or a semi-curved board, it is preferable to use a projector 4 that is compatible with a curved screen. Note that the mirroring linkage in the present invention means a function of projecting the display and writing contents of the electronic whiteboard 2 directly onto the screen 8 via the projector 4 in real time.

[0023] The screen unit 3 is attached so as to straddle slide rails 5, 6 installed along the upper and lower edges of the existing blackboard 1, and is movable along the slide rails 5, 6. The screen 8, which is rolled up and stored inside the cylindrical unit body 7 of the screen unit 3, is a magnetic screen equipped with a magnet on its back surface, and an end bar 9 at one end is fixed to the surface of the existing blackboard 1 by screws or the like. As the screen unit 3 is moved along the upper and lower slide rails 5, 6, the screen 8 is pulled out from the unit body 7 and magnetically attached to the surface of the existing blackboard 1. If the existing blackboard 1 is a curved or semi-curved blackboard, the screen is magnetically attached so as to curve along the curved surface.

[0024] Although not shown, a mechanism is built into the unit body 7, which automatically rolls up the screen 8 when it is released after being pulled out, just like a general roller screen. Rollers 11, 12 that engage with and roll on the slide rails 5, 6 are attached to the upper and lower ends of the unit body 7. A rotating bar 15 equipped with a handle 16 is also attached to the unit body 7 so as to be rotatable about its axis, and fixing pins 17, 18 that engage with stoppers 13, 14 fixed to the ends of the slide rails 5, 6 are protruding from the upper and lower surfaces of the rotating bar 15.

[0025] When the unit body 7 is pulled sideways along the guide rails 5, 6 by holding the handle 16 with the screen 8 rolled up as shown in FIG. 1, the screen 8 is pulled out, and the pulled-out screen 8 is immediately magnetically attached to the existing blackboard 1.

[0026] When the unit body 7 is pulled to the end and the fixed pins 17, 18 of the rotating bar 15 hit the crests of the stoppers 13, 14, and then the rotating bar 15 is pulled further while rotated (Figs. 6(A) and (B)), the fixed pins 17, 18 pass over the crests and are locked on the crests (Fig. 6(C)). When the handle 16 is released in this state, the screen 8 remains pulled out. When the fixed pins 17, 18 are released after passing over the crests by performing the above operation in reverse, the automatic screen winding mechanism of the unit body 7 is activated and the screen moves along the slide rails 5, 6 while winding up.

[0027] The multi-functional electronic whiteboard system according to the present invention is constructed mainly to realize the GIGA School by utilizing an existing blackboard and leaving some space for writing on the board, but it can be adopted in schools, preparatory schools, public facilities, commercial facilities, hospitals, and any other facilities. The electronic whiteboard 2 used in the multi-functional electronic whiteboard system according to the present invention is equipped with a computer function, and the written and projected contents can be saved as they are, and can be enlarged and projected onto a screen 8 via a projector 4 (mirroring projection). This allows for smooth lessons, as the teacher's body will no longer get in the way of students being unable to see what is being written on the electronic whiteboard.

[0028] Although not shown in the figure, the realization of the GIGA School Initiative also includes a teacher's terminal used by the teacher and a student's terminal provided for each student. Typically, the teacher's terminal is a tablet or smartphone, and the student's terminal is a tablet. The teacher's terminal and the student's terminal are connected to the electronic whiteboard 2 via Wi-Fi, and are set up to enable mutual communication between the electronic whiteboard 2 and each terminal (see Figure 7).

[0029] On the parts of the existing blackboard 1 that are not covered by the electronic blackboard 2 and the screen 8, it is possible to write on the board with chalk or the like as in the conventional method. If the screen 8 is not pulled out, the area that can be written on the board is expanded. In order to make it possible to input the contents of the writing on the board to the electronic blackboard 2, it is also possible to provide a plurality of sensors (not shown) that detect the movement of chalk, markers, fingertips, etc. on the periphery of the existing blackboard 1. As the sensors, the same infrared blocking type sensors as those used in general electronic blackboards can be used. In this case, the output signal from the sensor corresponding to the contents of the writing on the board is input to the electronic blackboard 2, and is displayed as is on the electronic blackboard 2, and is also converted into digital data and saved. The saved data can be shared and effectively used by teachers and students.

[0030] A second embodiment of the method for constructing a composite electronic whiteboard system according to the present invention is as follows: -A method for constructing a comprehensive electronic whiteboard system that can realize the GIGA School Initiative by utilizing a large existing whiteboard installed in a school classroom, etc. - a step of installing an electronic whiteboard on one end side surface of the existing whiteboard; - a step of fixing a wall-mounted whiteboard on the other end surface of the existing blackboard; -The method includes a step of installing a projector that is linked to the electronic whiteboard in a mirroring manner above the existing whiteboard.

[0031] The integrated electronic whiteboard system according to the second embodiment of the present invention is constructed by the above-mentioned method, and is characterized in that it includes an electronic whiteboard 2 installed on one end surface of an existing whiteboard 1, a wall-mounted whiteboard 21 fixed on the other end surface of the existing whiteboard 1, and a projector 4 that is installed above the existing whiteboard 1 and is in mirroring connection with the electronic whiteboard 2 (see Figures 8 and 9).

[0032] The electronic whiteboard 2 can be installed in any manner, but as in the first embodiment, it can be easily installed by using, for example, a commercially available TV wall mount bracket 22. The projector 4 can also be installed in the same manner as in the first embodiment.

[0033] Various types of wall-mounted whiteboards 21 are commercially available, and it is preferable to use a relatively thin and lightweight one. The wall-mounted whiteboard 21 can be attached by adhesion, magnetic attachment, screw fastening, or any other method. However, as described above, the repair work of the blackboard requires a lot of labor, and since there is a demand to carry out the work for thousands of classrooms in a school in one area within a very short period of time, the most important issue is to complete the work in a short time. Therefore, in the present invention, it is recommended to carry out the work by magnetic attachment, which is the most convenient method. When this method is used, the wall-mounted whiteboard 21 with the magnet 23 fixed to the back side is brought to the site and simply magnetically attached to the existing blackboard 1, so that the work can be completed by two workers in a few seconds. In addition, the position can be adjusted.

[0034] Many of the currently existing blackboards 1 are curved or semi-curved blackboards. In such cases, the gap between the surface of the existing blackboard 1 and the wall-mounted whiteboard 21 is uneven (see FIG. 9), so the back surface of the wall-mounted whiteboard 21 is fixed to the existing blackboard 1 via a spacer whose height varies according to the distance from the surface of the existing blackboard 1. The magnet 23 can fulfill the role of this spacer. Since the curvature of a curved blackboard is known, it is easy to prepare magnets 23 of different heights in advance to match it and fix them to the back surface of the whiteboard 21. [Industrial Applicability]

[0035] As described above, the present invention has the effect of making it possible to easily and at low cost, in a very short time without requiring a large number of manpower, by utilizing large existing blackboards installed in school classrooms, etc., and capable of realizing the GIGA School Project while leaving some space for writing on the board, and therefore has great industrial applicability.
