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. 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 can use an electronic pen as an input device. The user can draw or draw on the electronic board using the electronic pen. At this time, the user can change the color, thickness, etc. of the electronic pen by using the environment setting function of the electronic board when using the electronic pen. For example, the user can utilize a specific function necessary by selecting a setting change menu of the electronic pen displayed as a pop-up window on one side of the copyboard. In this case, the user has to repeatedly perform a series of operations of moving to one side of the copyboard to select the setting change menu of the electronic pen, and again selecting the setting change menu of the electronic pen to change the setting of the electronic pen. Such an electronic blackboard is required to improve user convenience by providing a setting change function of the electronic pen with a focus on the user who uses the electronic pen.

1 is an exemplary view of a copyboard to which the present invention is applied.

As shown in Fig. 1, the copyboard 1 to which the present invention is applied can be a projection type copyboard (Fig. 1 (a)) or a display-integrated copyboard (Fig. 1 (b)).

The projection type electronic whiteboard (Fig. 1 (a)) includes a touch panel which irradiates video information to the whiteboard 4 by the beam projector 3 and has a wire insulated on the white board 4 as a sensing line, A capacitive touch panel, and an infrared touch panel. The touch panel can be touch or written by the hand 5, the electronic pen 6, the laser pointer 7, and the like.

And can be written by the hand 5 or the electronic pen 6. In this case, it is possible to use a touch sensing method such as a camera or an infrared ray method, for example, in the case of a remote optical touch such as the laser pointer 7 or the like.

As described above, the electronic whiteboard 1 to which the present invention is applied may be implemented as a projection type or a display integrated type. However, for the convenience of explanation, the case where the infrared type is applied to the projection type electronic whiteboard is described, but not limited thereto Will be readily apparent to those skilled in the art.

FIG. 2 is a configuration diagram of an electronic whiteboard for changing functions using an external shape of an object according to an embodiment of the present invention.

2, an electronic whiteboard (hereinafter, referred to as "electronic whiteboard") 100 that changes its function using an external shape of an object according to an embodiment of the present invention includes a display panel 131) to display and display the screen information on the whiteboard. The object 10 may be an electronic pen (or a digitizer, a stylus), a hand, or the like, but is preferably an electronic pen. The electronic whiteboard 100 includes a touch panel 110 and a host 120. In addition, the electronic whiteboard 100 can constitute the electronic whiteboard system together with the electronic pen.

First, the touch panel 110 is driven by infrared rays. That is, the touch panel 110 includes a plurality of light emitting devices 112a and 113a arranged to calculate X and Y coordinates along four edges of the base substrate 111 and the base substrate 111, And a plurality of light receiving elements 112b and 113b provided corresponding to the light emitting elements 112a and 112b and receiving light emitted from the light emitting elements 112a and 113a. Here, the base substrate 111 may be glass, a flexible film, or the like. The light emitting devices 112a and 113a and the light receiving devices 112b and 113b may be disposed on opposite sides of the base substrate 111 or may be alternately arranged on the respective sides of the base substrate 111. [ In addition, the light emitting elements 112a and 113a and the light receiving elements 112b and 113b can be stacked in two layers and arranged on each rim.

The touch panel 110 can sense a touch input of the object 10 by detecting a change in the amount of received light received through the plurality of light receiving elements 112b and 113b from the light emitted from the plurality of light emitting elements 112a and 113a . That is, since the light emitted from the light emitting elements 112a and 113a is intercepted and blocked by the object 10, the amount of light received into the light receiving elements 112b and 113b changes.

The change in the amount of received light sensed by the light receiving elements 112b and 113b can form a type that can be distinguished according to the external shape of the object 10. [ That is, when the external cross-sectional shape of the object 10 is different, such as a circle, a triangle, or a quadrangle, the type of change in the amount of light received by the light-receiving elements 112b and 113b may be changed accordingly. In other words, the external cross-sectional shape of the object 10 can be identified using the type of change in the amount of received light of the light-receiving elements 112b and 113b.

Here, the object 10 may form an outer shape having an arbitrary shape and a cross-sectional area, but may be formed in an outer cross-sectional shape (for example, a triangle, a rectangle, a circle, etc.) having a predetermined cross- . To this end, the object 10 preferably includes a component having a predetermined external cross-sectional shape as described above in a touch portion that touches the touch panel 110.

Therefore, when the touch input of the object 10 is sensed, the copyboard 100 identifies the external cross-sectional shape of the object 10 using the type of change in the amount of light received by the object 10, (For example, changing the color of the electronic pen, etc.) of the electronic pen.

The touch controller 115 controls the driving circuit 114 for driving the touch panel 110. At this time, the driving circuit 114 is connected to the light emitting elements 112a and 113a and the light receiving elements 112b and 113b to control them. The touch controller 115 may include a drive circuit 114. The touch controller 115 confirms the change in the amount of received light of the light receiving elements 112b and 113b as the touch input result when the object 10 is touched and provides the result to the host 120. [ Here, the touch controller 115 confirms the change of the received light amounts of the received light amounts 112b and 113b as the 'touch input detection result' of the infrared type touch panel 110. However, in the case of the touch panel 110 of another type, Touch input results can be checked. For example, the touch controller 115 may be a capacitance value as a 'touch input detection result' in the case of the electrostatic touch panel 110.

The electronic whiteboard 100 may include touch input means such as a keyboard 132, a mouse 133, a microphone 134 and a camera 136 as well as a touch input means through the touch panel 110. [ In addition, the copyboard 100 may include output means such as a beam projector 131, a speaker 135, and the like.

In addition, the touch panel 110 functions as a cover window of the copyboard 110, and may further include a cover window on the top.

FIG. 3 is a block diagram of the host shown in FIG. 2, and FIGS. 4 to 6 are views illustrating an example of changing functions using an external shape of an object to which the present invention is applied.

As shown in FIG. 3, the host 120 may be connected to a panel board or a white board including the touch panel 110. The host 120 may control the input unit 130a and the output unit 130b. The input unit 130a refers to all means that are input to the electronic whiteboard 100 such as the keyboard 132, the mouse 133, and the microphone 134. [ The output unit 130b refers to all means output from the electronic whiteboard 100 such as the beam projector 131, the speaker 135, and the printer (not shown).

The host 120 may be a device such as a PC, a mini PC, or a tablet, which is embedded in the form of a chip on the electronic whiteboard 100 or connected to the electronic whiteboard 100 by wire or wireless. In the case of the projection type electronic whiteboard, the host 120 may be implemented in the form of a PC or a mini PC installed on the back of the boarder board or the whiteboard.

As described above, the host 120 can be interlocked with the drive circuit 114 and the touch controller 115. The touch controller 115 detects a touch input of the object 10 through the touch panel 10. That is, the touch controller 115 detects a change in the amount of light received by the light receiving elements 112b and 113b according to the external shape of the object 10.

On the other hand, the host 120 includes an input / output (I / O) unit 121, a video controller 122, a central processing unit (CPU) 123, a communication unit 124,

The input / output unit 121 controls the input / output of the entire system of the copyboard 100. At this time, the input / output unit 121 interlocks with the input unit 130a and the output unit 130b. The input / output unit 121 processes the input of all the means input from the input unit 130a to the copyboard 100 and processes the output of all means output to the copyboard 100 via the output unit 130b. The video controller 122 is connected to the central processing unit 123 and can display an image with the beam projector 131. The central processing unit 123 controls the entire system of the copyboard 100 including the touch panel 110. The communication unit 124 communicates with the object 10 (e.g., an electronic pen) or connects the electronic whiteboard 100 to the Internet, for example, to browse the web.

The memory 125 stores a system operating program (OS) 125-1, a touch driver 125-2, a copyboard application program 125-3 and a function changing program 125-4 .

The system operation program 125-1 performs functions of controlling, managing, and processing the entire system. The touch driver 125-2 provides an interface environment for controlling the touch panel 110 through the touch controller 115. [ The electronic copyboard operation program 125-3 is a program that can perform the electronic copy function of the electronic copyboard 100. [

The function change program 125-4 identifies the external cross-section of the object 10 according to the type of change in received light amount sensed according to the external shape of the object 10, Changing the color of the pen, and the like).

Such a function changing program 125-4 may be installed in the usual electronic whiteboard 100 according to the user's needs, or may be provided in advance on the electronic whiteboard 100 and provided to the user in a basic specification. In the former case, the user can download the function change program 125-4 through the website provided by the manufacturer of the electronic whiteboard 100 and install the function change program 125-4 on the electronic whiteboard 100, or the manufacturer of the electronic whiteboard 100 The function change program 125-4 can be installed using a storage medium (CD, USB, etc.) provided. In addition, the function changing program 125-4 may be installed as a separate program from the electronic whiteboard operating program 125-3 as shown in FIG. 3, but may also be installed as a single integrated program.

Hereinafter, the process of changing the specific function of the copyboard 100 in conjunction with the function change program 125-4 will be described in detail.

First, the central processing unit 123 preferably performs a registration procedure for the object 10 for interworking with the function change program 125-4 in advance. For example, when the object 10 is provided integrally with the copyboard 100, a registration procedure may be performed before the object is provided to the user, and when the object 10 is provided separately to the copyboard 100, The registration procedure can be performed in advance. At this time, the function change program 125-4 may provide a user interface for performing the registration procedure for the object 10. [

As described above, the function changing program 125-4 distinguishes the change in the amount of light received by the light receiving elements 112b and 113b according to the external shape (i.e., external cross-sectional shape) of the object 10 through the object registration procedure And connects the specific functions to be performed in the copyboard 100 according to the change in the amount of received light. Accordingly, the function changing program 125-4 enables the electronic whiteboard 100 to perform a specific function according to the outline of the object 10. [

For example, the function change program 125-4 manages the specific function to be performed in the electronic whiteboard 100 by associating the 'type of change in the amount of received light according to the external shape of the object 10'. At this time, the function changing program 125-4 may change the light receiving amount change type according to the external shape of the object 10 such as a circle, a triangle, The color of the electronic pen is set to 'green' (see FIG. 5), and the color is set to 'red' (see FIG. 4) In the case of 'change in the amount of light received by the rectangle C', the color of the electronic pen may be set to 'blue' (see FIG. 6).

Next, when the central processing unit 123 detects the touch input of the object 10, the central processing unit 123 confirms the type of change in the amount of received light of the object 10 through the function change program 125-4. At this time, the central processing unit 123 confirms a specific function corresponding to the received light amount change type if it corresponds to the previously registered light amount change type. Then, the central processing unit 123 causes the copying board application program 123-3 to perform a specific function corresponding to the received light quantity change type through the copying board 100. [

When the user touches the circular object 10 on the copyboard 100, the copyboard 100 can perform a predetermined color change function according to the 'received light amount variation type for the circle' And set to 'red' (see FIG. 4). When the user touches the triangular object 10 on the copyboard 100, the copyboard 100 sets the predetermined color changing function to 'green' according to the 'change in the amount of light received by the triangle' 5). When the user touches the rectangular object 10 on the copyboard 100, the copyboard 100 sets the predetermined color changing function to 'blue' according to the 'change in the amount of light received by the quadrangle' ( 6).

On the other hand, if the central processing unit 123 does not correspond to the pre-registered light receiving amount change type, it interlocks with the electronic whiteboard application program 123-3 to perform necessary procedures.

On the other hand, the function changing program 125-4 can distinguish the type of change in the amount of light received by considering the change in the amount of received light detected from the light receiving element 112b in the X-axis direction and the light receiving element 113b in the Y- However, it is also possible to distinguish the type of change in the amount of light received by using the change in the amount of received light in the axial direction of either the X axis or the Y axis. For example, when the object cross-sectional shape of the object 10 is an equilateral triangle, a square, or a circle, the function change program 125-4 may have similar types of change in the amount of light received in the X- or Y- It is possible to distinguish types of changes in the amount of received light.

In addition, the function change program 125-4 may set a predetermined setting time (for example, 3 seconds, 5 seconds, etc.) to distinguish the touch input for the function change of the present invention from the normal touch input of the object 10. [ ). ≪ / RTI > That is, when there is a touch input whose position of the object 10 is changed within a predetermined set time, the function change program 125-4 determines that the touch input is a normal touch input. If the position of the object 10 is In the case where there is an unchanging touch input, it can be distinguished as a touch input for changing the function of the present invention. The function change program 125-4 can provide the user with a user environment in which the set time can be changed.

7 is a diagram illustrating a method of changing a function using an outline of an object according to an embodiment of the present invention.

First, the copyboard 100 registers the object 10 (S200). Here, the object 10 is preferably an electronic pen. At this time, the copyboard 100 registers the type of change in the amount of received light according to the outline (that is, the outline cross-sectional shape) of the object 10 and connects the specific function to be performed in the copyboard 100 according to the change in the amount of received light.

Then, the copyboard 100 senses the touch input of the object 10 (S202), and confirms the type of change in the amount of received light of the object 10 (S203).

Then, the copyboard 100 confirms the function corresponding to the light receiving amount change type of the object 10 (S204). At this time, the copyboard 100 performs the corresponding function (S205).

Next, when the central processing unit 123 detects the touch input of the object 10, the central processing unit 123 confirms the type of change in the amount of received light of the object 10 through the function change program 125-4. At this time, the central processing unit 123 confirms a specific function corresponding to the received light amount change type if it corresponds to the previously registered light amount change type. Then, the central processing unit 123 causes the copying board application program 123-3 to perform a specific function corresponding to the received light quantity change type through the copying board 100. [ On the other hand, if the central processing unit 123 does not correspond to the pre-registered light receiving amount change type, it interlocks with the electronic whiteboard application program 123-3 to perform necessary procedures.

FIGS. 8A and 8B are views showing the electronic pen according to the first embodiment of the present invention, and FIG. 9 is a cross-sectional view taken along the line A-A 'of the external shape of the touch input unit of the electronic pen.

8A and 8B, the electronic pen 310 according to the first embodiment of the present invention corresponds to the object 10 used for changing the function of the electronic whiteboard 100, The electronic whiteboard system can be constituted.

The electronic pen 310 may include a touch input unit 311 and a body 312. At this time, a plurality of touch input units 311 can be used and can be used interchangeably. In addition, the touch input unit 311 can be formed as an integral structure with the body 312.

First, the touch input unit 311 is configured to perform touch input to the touch panel 110 of the copyboard 100. That is, when touch input of the touch panel 110 of the copyboard 100 is performed, the touch input unit 311 controls the light emitted from the plurality of light emitting devices 112a and 113a disposed around the touch panel 110 . At this time, the touch input unit 311 may be formed of a material that does not transmit infrared rays in order to shield the light emitted from the light emitting devices 112a and 113a. Thus, the amount of light received by the plurality of light receiving elements 112b and 113b disposed around the touch panel 110 is changed.

Here, the plurality of light emitting devices 112a and 113a can irradiate light with a predetermined diffusion angle [theta]. Accordingly, the touch input unit 311 is preferably formed to have a predetermined thickness d1 for shielding light emitted from the plurality of light emitting devices 112a and 113a having a predetermined diffusion angle [theta]. Here, it is assumed that light emitted from the light emitting devices 112a and 113a reaches the touch input unit 311 at a position spaced apart from the base substrate 111 by a predetermined height d2. It is preferable that the thickness d1 of the touch input unit 311 is greater than or equal to the height d2 of the point where the light emitted from the light emitting devices 112a and 113a reaches (i.e., d1? D2).

The external shape of the object 10 or the electronic pen 310 means the shape of the portion where the touch input is performed with respect to the touch panel 110. The external shape of the object 10, .

9, the outer shape cross-sectional shape of the touch input unit 311 may be circular, triangular, square, or the like, but is not limited thereto. Here, for convenience of explanation, a description will be given of a case where the external shape cross-section of the touch input unit 311 is one of a circle, a triangle, and a rectangle. At this time, in the case of the infrared touch panel 110, the outline cross-sectional shape of the touch input unit 311 blocks the light emitted from the plurality of light emitting devices 112a and 113a disposed around the touch panel 110 Shape is sufficient. Accordingly, the touch input unit 311 may form a shape that fills the entire area of the outer shape cross section as shown in FIG. 9A, or a region other than a border area that shows the shape of the outer shape cross section as shown in FIG. 9B The shape to be removed can be formed.

On the other hand, in the case of the electrostatic touch panel, since the touch input unit 311 does not need to cut off the light emitted from the light emitting elements 112a and 113a, The thickness d1 described above need not be considered. In this case, the touch input unit 311 may be provided with a material capable of causing a change in the capacitance value on the contact surface of the touch panel.

The touch input unit 311 is coupled with a body 312 serving as a handle of a user to form the electronic pen 310. Referring to FIGS. 8A and 8B, the touch input unit 311 is provided with an extension for forming a long end, and the body 312 forms a receiving groove for receiving one end of the touch input unit 311. Accordingly, the extended portion of the touch input unit 311 can be inserted into and engaged with the receiving groove of the body 312. However, the touch input unit 311 can be coupled to the body 312 by various methods (for example, interference fit, screw connection, magnet coupling, etc.) of the extension part and the receiving groove.

The body 312 may be formed of a material (e.g., rubber, plastic, or the like) for user's convenience and may have a shape (for example, a knob shape or the like) (For example, an octagon shape, an angular shape, or the like).

FIGS. 10A and 10B are views of an electronic pen according to a second embodiment of the present invention, and FIGS. 11A and 11B are diagrams of an electronic pen according to a third embodiment of the present invention.

10A and 10B, the electronic pen 320 according to the second embodiment of the present invention can be connected between the touch input unit 321 and the body 322 through the rotation unit 323. [ That is, when the touch input unit 321 touches the touch panel 110, the body 322 can be rotated and driven at a predetermined angle? ₁ by the rotation unit 323. That is, the turning portion 323 of the electronic pen 320 according to the second embodiment has a turning radius of a predetermined angle? ₁ between the touch input portion 321 and the body 322. [ This is because, when the user uses the copyboard 100 standing upright, the body 322, which serves as the handle of the user, can be inclined or rotated to take various positions according to the position of the user's handle, .

The tilting portion 323 may be coupled with the touch input portion 321 and the body 322 by various connecting methods. For example, the turning portion 323 can be combined with a touch input portion 321 having various outline shapes, using a magnet, so as to have ease of connection or ease of replacement. That is, the tilting portion 323 may be formed of a magnet, and the touch input portion 321 may be formed of a metal material having a contact surface to be engaged with the tilting portion 322. In addition, the swivel portion 323 can be coupled with the body 322 in various ways, such as a screw coupling type or a forced fit type.

The touch input unit 321 and the swivel unit 323 may form a contact surface with a curved surface to facilitate rotational driving. That is, when the touch input unit 321 forms a concave curved surface, the turning unit 323 can form a convex curved surface.
