Description

TECHNICAL FIELD [0001] The present invention relates to an electronic blackboard for activating a touch area according to a user's access, and a method for activating an electronic blackboard touch area using the electronic blackboard,

The present invention relates to an electronic blackboard for activating a touch area according to a user's access, and more particularly, to a method for activating a touch area according to a user's access to recognize a user's touch at a high speed And a method of activating an electronic blackboard touch area using the electronic blackboard.

The classroom environment is improved so much that the video system is utilized or the class to move to the classroom according to the characteristics of the curriculum is also inexpensive. Recently, the number of students per class has been reduced to around 30, and computers have been installed in classrooms. In the center of the classroom, there is an electronic board which induces dynamic interaction between teachers and students.

Generally, an electronic board is an image device that directly or indirectly recognizes a touch on the screen by being combined with a FPD (Flat Panel Display) panel or a whiteboard, which is usually 70 to 100 inches. In Korea, the electronic blackboard was introduced in the early 2000s, and about 60% of the elementary and junior high schools in the country now have three or four electronic blackboards.

Depending on the position of the light source, the electronic board is divided into an FPD integral type, a front projection type, and a rear projection type. Of these, the rear projection type is not used much more than the other two types because of the disadvantage of having a certain space behind the panel. The integrated FPD is a touch panel attached to the edge of LCD or LED panel, and the light source is embedded in the panel. There are about 30 SMEs in Korea. The front-projection type is the world's most widely distributed product, with the light source located on the top of the whiteboard. On the other hand, there is a bar type which is a front projection type and an inexpensive price type. Conventional front type products require an electromagnetic field board to recognize a touch, whereas bar type products can be used anywhere on a flat surface such as a wall or a blackboard There is an advantage of excellent mobility.

Such an electronic blackboard is composed of a large-sized screen. In order to recognize a touch on a large-sized screen, it is necessary to confirm whether or not a user touches the entire screen. At this time, the copyboard confirms whether or not the user touches an area not used by the user.

Accordingly, the electronic whiteboard may be difficult to process the user's touch recognition result quickly because of the process of confirming whether the user touches the area not used by the user. That is, the electronic whiteboard can perform an unnecessary touch recognition process by checking whether a user touches an area that does not require a process of confirming whether the user has a touch, such as an area not used by the user.

Therefore, there is a need to provide the user with a result of the touch recognition at a high speed without performing an unnecessary touch recognition process in consideration of the position of the user with respect to the electronic whiteboard.

It is an object of the present invention to provide a method and apparatus for recognizing a touch of a user by recognizing a touch of a user at a high speed by providing a partial touch region of a copyboard by determining a touch region usable by a user, And a method of activating the touch panel using the touch panel.

An electronic board according to an embodiment of the present invention includes an input unit for sensing a user approaching the electronic board; And a central processing unit for performing a touch area activation function for determining a touch area usable by the user and activating the corresponding touch area by confirming the access position of the user to the copyboard through the input unit.

And a memory for storing a touch area activation program capable of performing a touch area activation function in cooperation with the central processing unit.

The central processing unit confirms the position of the user in the horizontal direction of the electronic whiteboard to confirm the approach position of the user.

The input unit detects a user's access using a camera or a sensor.

The central processing unit determines the touch area in which the adjacent touch area is further extended based on the access position of the user as a touch area that can be used by the user.

The central processing unit divides the entire touch area into one or more areas, and when the access position of the user is within the specific touch area divided, the central processing device sets the divided specific touch area as a touch area that the user can use by the user .

According to another aspect of the present invention, there is provided a method of activating a touch panel of a copyboard, comprising: confirming an access position of a user approaching the copyboard; Determining a touch area usable by a user based on a predetermined touch area determination method according to an access position of the user; And activating the determined touch region.

The checking step confirms the position of the user in the horizontal direction of the copyboard, and confirms the approach position of the user.

Before the confirmation step, the touch area determination method is set.

The touch area determination method determines the touch area in which the adjacent touch area is further extended based on the access position of the user as a touch area that can be used by the user.

The touch area determination method includes dividing an entire touch area into at least one area, and when the access position of the user is within the specific touch area, .

The present invention provides a partial touch area of the electronic blackboard to a user by determining a touch area that can be used by a user according to an access position at which the user approaches the electronic blackboard, thereby not only recognizing the user's touch at a high speed, The user's touch can be displayed.

Further, since the present invention can determine a partial touch area usable by a user and provide the partial touch area to the user, the power consumption of the copyboard can be reduced.

In the case of a projection type copyboard, a PC or mini PC can be wired or wirelessly connected to the platter screen and placed on the back of the platter screen.

The touch panel 10 is connected to the touch controller 14, and the touch controller 14 controls the operation of the touch panel 10. Here, the touch controller 14 may be included in the host 50.

The input unit 30a means any means that is input to the electronic whiteboard 1 such as the keyboard 31, the mouse 32, the microphone 34, the camera 35, and the sensor 36. [ In particular, the camera 35 and the sensor 36 can be used as means for sensing or recognizing a user approaching the copyboard 1. The output unit 30b refers to all means output from the electronic whiteboard 1 such as a speaker 33, a beam projector 3, and a printer (not shown).

The host 50 receives the touch input from the touch controller 14 that senses the touch input of the user input through the touch panel 10. [ The host 50 also includes an input / output (I / O) unit 51, a video controller 52, a central processing unit (CPU) 53, a communication unit 54 and a memory 60.

The input / output unit 51 controls the input / output of the entire system of the copyboard 1. At this time, the input / output unit 51 interlocks with the input unit 30a and the output unit 30b. The input / output unit 51 processes the input of all the means input from the input unit 30a to the copyboard 1 and processes the output of all means output to the copyboard 1 via the output unit 30b. The video controller 52 is connected to the central processing unit 53 so that the video can be displayed on the display panel 12 or displayed by the beam projector 3. [ The central processing unit 53 controls the entire system of the electronic whiteboard 1 including the touch panel 10. The communication unit 54 communicates with the stylus 6 or connects the electronic whiteboard 1 to the Internet so as to be able to browse the web, for example.

The memory 60 stores a touch area activation program 61, a copyboard application program 63, a touch driver 65 and a system operation program (OS) At this time, the touch area activation program 61 has a function (hereinafter referred to as "touch area activation function") for partially activating only the touch area necessary for the user to use in consideration of the approach position of the user who intends to use the electronic whiteboard 1, And the like. In this way, the electronic whiteboard 1 can utilize the touch area activation function by mounting the touch area activation program 61 in the memory 60. [

The electronic board operation program (63) is a program that can perform the electronic board function. The touch driver 65 controls the touch panel 10 so as to perform the touch area activation function. The system operation program 67 functions to control, manage and process the entire system.

Hereinafter, the process of performing the touch area activation function will be described in detail.

The central processing unit 53 can work with the touch area activation program 61 to perform the touch area activation function. That is, the central processing unit 53 can perform the touch area activation function based on the operation of the touch area activation program 61. [ Hereinafter, the case where the central processing unit 53 controls the touch area activation function while the touch area activation program 61 is executing will be described for convenience of explanation.

First, the central processing unit 53 can confirm the approach position of the user approaching the copyboard 1 to use the copyboard 1 through the input unit 30a. The user uses the copyboard 1 while moving along the horizontal direction (i.e., the X-axis direction) with the ground. Accordingly, the electronic whiteboard 1 can be divided into a touch area used by a user and a touch area not used by a user as the user moves in the horizontal direction. At this time, the user can use them all in the vertical direction (i.e., the Y-axis direction) of the copyboard 1 when positioned at a specific point in the horizontal direction of the copyboard 1. Therefore, it is preferable that the central processing unit 53 confirms the approach position of the user only in the horizontal direction of the copyboard 1. The central processing unit 53 uses the sensor 36 that detects the position of the user's hand in the vertical direction of the copyboard 1 so that the central processing unit 53 can detect the user's approach position in the vertical direction of the copyboard 1 You can also check. However, a detailed description thereof will be omitted because it can be easily understood by those skilled in the art.

As described above, the central processing unit 53 confirms the position of the user in the horizontal direction of the copyboard 1 when checking the approach position of the user. At this time, the central processing unit 53 can confirm the access position of the user by using the camera 35 or the sensor 36 of the input unit 30a.

The central processing unit 53 extracts the characteristic of the user from the image input through the camera 35 and confirms whether the user approaches the electronic whiteboard 1 when checking the approach position of the user by using the camera 35 have. For example, the central processing unit 53 can recognize the user's face or the entire outline of the user through the corresponding image. At this time, the central processing unit 53 manages the image frame input through the camera 35 and the frame of the electronic whiteboard 1 in advance in correspondence with each other, You can see where the user is located in the direction.

Meanwhile, the central processing unit 53 can confirm whether the user approaches the electronic whiteboard 1 through the sensing signal sensed by the sensor 36 when confirming the access position of the user by using the sensor 36. For example, the sensor 36 may be any of a variety of infrared sensors, ultrasonic sensors, acoustic sensors, etc., which can sense the user's approach. A plurality of sensors 36 may be installed to determine at which point the user is located in the horizontal direction of the electronic copyboard 1. [

In addition, the central processing unit 53 can confirm the approach position of the user by using the phenomenon that the resonance is collapsed when the human being approaches through the electromagnetic field formed by applying the electric current to the touch panel 10.

Next, the central processing unit 53 determines the touch area (i.e., the touch area of the touch panel 10) of the electronic whiteboard 1 that can be used by the user according to the access position of the user. That is, the central processing unit 53 can expand the peripheral area to the touch area on the touch panel 10 based on the approach position of the user to activate the touch area of the copyboard 1. At this time, the central processing unit 53 does not activate the entire touch area of the touch panel 10, but activates the partial touch area of the touch panel 10 that the user can use according to the access position of the user. To this end, the central processing unit 53 can control the driving of the touch panel 10 through the touch driver 65 to activate the partial touch area of the touch panel 10. [

As described above, the central processing unit 53 drives the entire area of the touch panel 10 on the copyboard 1 by activating only the necessary touch area in the touch panel 10 when the user uses the copyboard 1 It is possible to recognize the touch of the user at a high speed and display the result of the touch recognition on the electronic whiteboard 1 quickly.

Here, the X-axis and Y-axis touch patterns may be insulated conductive wire patterns. The touch panel 10 touches the X-axis touch pattern at X1 To Xn, and the position of the Y-axis touch pattern can be displayed as Y1 to Yn.

The central processing unit 53 further activates the touch area of the adjacent touch panel 10 based on the user's access position 'Xk point' when the user's access position is identified as the 'Xk point' Of the partial touch area TA. That is, when the left adjacent touch area of the touch panel 10 is further activated (refer to FIG. 4A) based on the user's access position 'Xk point', the left and right adjacent touch areas of the touch panel 10 are further activated (See FIG. 4B), and further activating the right adjacent touch area of the touch panel 10 (see FIG. 4C).

Referring to FIG. 4B, the partial touch area TA of the touch panel 10 is additionally provided for the 'Xk-1 point' to the left and the 'Xk + 1 point' to the right with reference to the user access position 'Xk point' The touch area can be activated. In this case, it is possible to set the case where the user uses the electronic whiteboard 1 regardless of the left or right direction at the user access position 'Xk point' (for example, in a general case without taking the user's tendency into consideration).

Referring to FIG. 4C, the partial touch area TA of the touch panel 10 is further activated with respect to the 'Xk + 1 point, Xk + 2 point' to the right based on the user access position 'Xk point' . In this case, the user can set the case where the user uses the copyboard 1 mainly (for example, a right-handed user) in the right direction from the user-accessible position 'Xk point'.

Here, the central processing unit 53 further uses the touch area activation program 61 to set the direction of use (i.e., left, right, left and right) of the partial touch area TA, partial touch area TA) size (the size of the touch area to be activated), and the like, thereby adjusting the touch area usable by the user.

5A to 5C are views showing another embodiment of the touch area determination method of the electronic whiteboard.

5A to 5C show a case where the central processing unit 53 divides the entire touch area into one or more areas and then confirms that the user's access position is located in a specific touch area previously classified. (TA) that can be used.

5A to 5C, the central processing unit 53 divides the touch area (i.e., area A, area B, and area C) usable by the user in advance, And determines the corresponding touch area as a partial touch area TA that the user can use. First, when the user's access position is identified as 'any point within the A area', the central processing unit 53 determines the partial touch area TA available to the user as the 'A area' (see FIG. 5A) ), The central processing unit 53 determines the partial touch area TA that can be used by the user as the "B area" when the user's access position is identified as "any point within the B area" 5b). When the user's access position is identified as 'any point within the C area', the central processing unit 53 determines the partial touch area TA available to the user as the 'C area' (see FIG. 5C) ).

Here, the central processing unit 53 can adjust the partial touch area TA available to the user by setting the size of the touch area to be activated using the touch area activation program 61.
