The computer 100 may be built in the electronic blackboard 10 or may be provided separately and communicate with a plurality of electronic blackboards 10.

The electronic blackboard 10 includes a display surface 11 as a display unit for displaying the visual information S according to information from the computer 100, and four imaging sensors 14 for detecting an object in contact with the display surface 11. Have.
The electronic blackboard 10 is formed as a part of the display surface 11 at the outer edge portion on the display surface 11, and an electronic pen display area for transitioning to an electronic pen setting operation subroutine described later when the electronic pen 13 comes into contact with the electronic blackboard 10. 80.

As shown in FIG. 2, the electronic blackboard 10 is connected to a computer 100, and an image input unit 15 that reads image information and position information (x) that is a coordinate of the electronic pen 13 that is in contact based on information from the imaging sensor 14. , Y).
The electronic blackboard 10 includes a storage unit 17 that stores information including position information (x, y) input to the operation input unit 16 and visual information S displayed on the display surface 11, and setting of the electronic pen 13. And an electronic pen management unit 18 that records and manages information, operation states, and the like.
Although the operation input unit 16 inputs the position information (x, y) of the electronic pen 13 here, the operation input unit 16 is not limited to the electronic pen 13 and may be an object such as a finger or a pen.

  Although the electronic blackboard 10 includes the image input unit 15, the operation input unit 16, the storage unit 17, and the electronic pen management unit 18 here, the computer 100 may have these functions.

As shown in FIG. 3, the electronic pen management unit 18 is associated with identification information Q as an arbitrary electronic pen ID, availability information indicating whether or not the electronic pen 13 is in a usable state, and identification information Q. The discrimination information and the status information R of the electronic pen 13 are recorded.
Here, the identification information Q is an ID uniquely given to each of the electronic pens 13 and is a unique number that does not overlap each other.

The availability information is information for managing a determination state for determining whether the electronic blackboard 10 can use the electronic pen 13, that is, whether the position information (x, y) can be input. According to the state of each electronic pen 13, four cases are described: usable, use stop, no response, and use of another device. That is, the availability information indicates whether or not the electronic pen 13 is in a usable state in which position information (x, y) can be generated.
The discrimination information is unique information of the electronic pen 13 that is arbitrarily set at the time of a registration operation to be described later so that the user can easily understand. Here, K01, K02, red 1, and R02 are easy for the user to discriminate. It is represented by a character string.
The state information R is visual characteristic information including information on the color, shape, and size of the locus displayed when each electronic pen 13 performs a writing operation on the electronic blackboard 10.
The electronic pen management unit 18 records the unique information of the usability information, the discrimination information, and the state information R associated with the identification information Q as an electronic pen management table.

As shown in FIG. 4, the electronic pen 13 is a pen-shaped pointing device with a sharp tip, and is held on the display surface 11 by a grip portion 13 b for a user to perform a writing operation on the electronic blackboard 10.

The electronic pen 13 has a contact detection unit 132 that determines whether or not the tip portion 13a is in contact with the display surface 11, and that the contact detection unit 132 has detected the contact between the display surface 11 and the tip portion 13a. A light emitting unit 133 that is an LED that emits light as a condition.
The contact detection unit 132 has a function as a pressure sensor, and also has a function as a pressure detection unit that detects, as a writing pressure, the strength with which the distal end portion 13a is pressed against the display surface 11.
In the present embodiment, one light emitting unit 133 is disposed at a position that is not hidden by the user of the gripping unit 13b. However, the light emitting unit 133 may be provided at the distal end portion 13a or a plurality of light emitting units 133 may be provided. By photographing the light from the light emitting unit 133 using the imaging sensor 14, the position information (x, y) of the electronic pen 13 can be obtained with higher accuracy by the same method as triangulation.

In this embodiment, the communication unit 30 is disposed on the electronic blackboard 10 and manages communication of data 31 between the electronic blackboard 10 including the identification information Q and the electronic pen 13 by wire and / or wireless.
A data configuration of data 31 transmitted and received by the communication unit 30 is shown in FIG.
The data 31 includes transmission destination identification information Q ₁ included in the identification information Q, transmission source identification information Q _2, and a communication content body D. And destination identification information Q _1, and the transmission source identification information Q _2, is a numeric string for specifying a receiving party, a few tens digit ID for identifying the number of devices.
The communication content body D contains a command string to be sent to the other party and observation data associated with written information. The communication content body D from the electronic pen 13 further includes observation information of the contact state of the tip portion 13a detected by the contact detection unit 132 and the writing pressure.
Thus, when the communication unit 30 performs communication, the identification information Q is included.
Further, as described later, the communication unit 30 can perform unspecified communication which does not specify the destination identification information Q _1.
In this case, all devices such as the electronic pen 13 and the electronic blackboard 10 that have received the communication process the contents.

As shown in FIG. 7, the computer 100 includes a CPU 101 that is electrically connected via a bus line 118 such as an address bus or a data bus, a ROM 102 that is a storage device, a RAM 103, and an SSD (Solid State Drive) 104. ,have.
The computer 100 includes a network controller 105, an external storage controller 106, a sensor controller 114, a GPU 112, and a capture device 111.

The CPU 101 controls an operation of the electronic blackboard system 100 by executing an execution command represented by an application.
The ROM 102 stores an IPL, and mainly stores a program executed by the CPU 101 at startup. The RAM 103 has a function as a work area when executing an application.
The SSD 104 is a non-volatile memory in which applications for detecting position information and data are stored.

  The network controller 105 performs control based on a communication protocol when communicating with the external device 300 or the electronic pen 13 via a network such as a LAN or a WAN.

The external storage controller 106 performs writing to or reading from the removable external memory 117.
The capture device 111 captures image information from the external device 300 and visual information S displayed on the electronic blackboard 10. That is, the capture device 111 has a function as the image input unit 15.
The GPU 112 is a drawing processor that calculates pixel values of a plurality of pixels arranged on the display surface 11 of the electronic blackboard 10.

  The sensor controller 114 is connected to the imaging sensor 14 and controls the imaging sensor 14 based on the light from the light emitting unit 133 to perform shooting.

  In the present embodiment, the computer 100 does not necessarily communicate directly with the electronic pen 13, and communicates via the communication unit 30. When the computer 100 communicates directly with the electronic pen 13, the computer 100 preferably includes an electronic pen controller 116 for receiving a pressing signal from the electronic pen 13.

The program executed by the CPU 101 may be provided in a state stored in the external memory 117, or may be obtained by downloading from the external device 300 or a predetermined server via the network controller 105. good.
In addition, such a program may be provided in a compressed state or may be provided in an executable format.

In such an electronic blackboard system 500, a plurality of electronic pens 13 are often used for one electronic blackboard 10 as in the present embodiment.
However, there has been a concern that simply performing wireless communication with these electronic pens will affect unrelated wireless communication devices in the vicinity and it will be difficult to encrypt communication contents.
Therefore, in the present embodiment, in order to specify the communication partner on a one-to-one basis, a pairing operation is performed in which the transmission source and the transmission destination are specified and linked. By including the transmission destination address and the transmission source address in the communication content by such a pairing operation, the communication partner is specified one-to-one, and the influence on other communication devices can be suppressed.

Further, when performing such a pairing operation, it is difficult to know which of the plurality of electronic pens 13 is linked to the electronic blackboard 10, that is, which electronic pen 13 is usable. There was also.
Therefore, in the present embodiment, as an example of an information processing method using such an electronic blackboard system 500, the electronic pen 13 is managed by operating according to the flow shown in FIG.

When the power of the electronic blackboard system 500 is changed from the OFF state to the ON state (step S101), the computer 100 transits to a use preparation state in which image information input from the external device 300 or the like is confirmed (step S102).
The image input unit 15 reads the image information input from the external device 300 and displays the visual information S on the display surface 11 (step S103).

When the use preparation is completed, the electronic blackboard 10 communicates with the electronic pen 13 via the communication unit 30 based on the identification information Q stored in the storage unit 17 or the electronic pen management unit 18, and updates the electronic pen management table. Is performed (step S104).
Step S104 is an identification information acquisition step for acquiring the identification information Q.
As already described with reference to FIG. 2, in the electronic pen management unit 18, the availability information, the discrimination information, and the state information R are recorded in association with the identification information Q.
The electronic pen management table is a database having the identification information Q as a main key, and the identification information Q is a unique number of each electronic pen.

After the electronic pen management table is updated, the communication unit 30 communicates with each of the surrounding electronic pens 13A, 13B, and 13C without specifying the other party, and each of the electronic pens 13A, 13B, and 13C. Check if the connection is successful.
Based on the electronic pen management table updated in step S104, the electronic blackboard 10 stores the simplified information on the usable electronic pen 13, which is normally communicated by the communication unit 30, in this embodiment, especially the electronic pen 13A. It displays on the electronic pen display area 80 (step S105).
For example, the simple information may be simply displayed on the outer peripheral edge of the display surface 11 with the discrimination information and the state information R. Specifically, among the discrimination information and status information R of the electronic pen 13A that can be used at present, a pen-shaped figure or a simple name may be displayed together. By displaying the electronic pen information, the user can easily identify the electronic pen 13A that can be used at present, and the convenience for the user is improved.
Step S105 is a communication step in which the communication unit 30 communicates the state information R and the identification information Q between the electronic blackboard 10 and the electronic pen 13.
In order to further simplify the determination, a character string such as “K01”, which is a simple name used in the determination information, is written on each of the electronic pens 13A, 13B, and 13C as shown in FIG. May be.

The electronic blackboard 10 transitions to the standby state in a state where the simple information of the usable electronic pen 13 is displayed (step S106).
In such a standby state, the electronic blackboard 10 is used for an event such as a touch operation by the user, an operation of the electronic pen 13, an ON / OFF state transition of the power supply unit 130 transmitted from the electronic pen 13 via the communication unit 30, and the like. Waiting for an event.
In step S106, when the electronic blackboard 10 detects the user's operation, for example, when the electronic blackboard 10 detects that the usable electronic pen 13A is in contact with the display surface 11 and performs the drawing operation (step S107), the electronic blackboard 10 Then, the process proceeds to a drawing operation subroutine shown in FIG.
Similarly, in step S106, when the electronic pen 13A comes into contact with the display surface 11 and a setting operation request for the electronic pen 13A is detected (step S108), the electronic blackboard 10 performs the electronic pen setting operation shown in FIG. Transition to a subroutine.
When neither operation is performed, the electronic blackboard 10 maintains a standby state.

  A drawing operation in which the user newly writes triangular drawing information P as shown in FIG. 1 to the existing visual information S displayed on the electronic blackboard 10 will be described.

The initial drawing state indicated by Start in FIG. 9 is a standby state in the main routine shown in FIG. 8, and the existing visual information S is displayed on the display surface 11 of the electronic blackboard 10.
The user uses the electronic pen 13A to perform a drawing operation that moves the electronic pen 13A in a state of being in contact with the display surface 11 along a triangular shape.
When the usable electronic pen 13A comes into contact with the display surface 11 by the user's operation, the light emitting unit 133 emits light on the condition that the tip portion 13a and the display surface 11 are in contact (step S301).
The communication unit 30 determines the content of communication sent from the electronic pen 13A on condition that the imaging sensor 14 detects the light from the light emitting unit 133 (step S302).
Specifically, the operation input unit 16 analyzes position information (x _A , y _A ) on the display surface 11 of the electronic pen 13A, and performs a command process to determine whether the electronic pen 13A performs a writing process on the display surface 11. Determine what to do.
In the present embodiment, the drawing operation is performed on the condition that the electronic pen 13A is in contact with the display surface 11. However, on the condition that a separate button is provided on the main body of the electronic pen 13 and the button is pressed. Transition to a drawing operation may be performed.

In the communication content determination step of step S302, when the operation input unit 16 determines that it is a writing process, the electronic blackboard 10 observes the position information (x _A , y _A ) of the electronic pen 13A.
The touch input unit 16 obtains position information (x _A , y _A ) of the distal end portion 13a based on the image captured by the image sensor 14 and the light from the light emitting unit 133 in the same manner as triangulation.

The communication unit 30 transmits the obtained position information (x _A , y _A ) to the computer 100.
The computer 100 analyzes the position information (x _A , y _A ) of the electronic pen 13A in real time and arranges it along the time series, thereby creating and displaying the locus of the position information (x _A , y _A ) as a line. Display on surface 11.
In other words, the electronic blackboard system 500 reads the position information (x, y) at each time point generated by the electronic pen 13 using the imaging sensor 14 when the user performs a drawing operation. 11 displays a trajectory (step S303).
That is, step S303 is a position information acquisition step for generating position information (x, y) on the display surface 11 of the electronic pen 13 in contact with the display surface 11 of the electronic blackboard 10.
In addition, the shape and size of the trajectory displayed at this time are determined based on the setting information of the electronic pen management table updated in step S104.

  When the drawing process instructed in step S303 ends, the electronic blackboard 10 transitions again to the standby state in step S106.

  Since the position information (x, y) of the electronic pen 13 can be easily obtained by reading the position information (x, y) using the imaging sensor 14 in this way, the electronic blackboard system 500 has an electronic blackboard having a touch panel function. Operates as a system.

If the operation of the electronic pen 13A is determined to be a command process by observing the position information (x _A , y _A ) in the communication content determination step in step S302, the corresponding process is performed (step S304).
In such command processing, for example, when the power supply unit 130 of the electronic pen 13A is turned off, or when the electronic pen 13A is changed to a setting to be used for another electronic blackboard, the electronic pen 13A transitions to a use stop state. Is mentioned. Thereby, the process of deleting the simple information of the electronic pen 13A presented on the display surface 11 is performed.
When the command processing instructed in step S304 ends, the electronic blackboard 10 transitions again to the standby state in step S106.

When the electronic pen 13 comes into contact with the electronic pen display area 80 displayed on the display surface 11 of the electronic blackboard 10, that is, when a setting operation request is made, the process proceeds to the electronic pen setting operation subroutine shown in FIG. (Step S201). In the present embodiment, the setting operation request is that the electronic pen 13 is in contact with the electronic pen display area 80. However, it is also possible that a button is provided on the main body of the electronic pen 13 and the button is pressed.
The electronic blackboard 10 displays the electronic pen management screen 70 as shown in FIG. 11 on the condition that the electronic pen 13 is in contact with the electronic pen display area 80, and transitions to the electronic pen management state (step S202). .
In the electronic pen management state, the electronic blackboard 10 performs unspecified communication with respect to all the electronic pens 13 within the communicable range of the communication unit 30, and the discrimination information, the state information R, and the use of each electronic pen 13 are used. The availability information and a registration button 71 for changing the setting of the availability information are displayed.
That is, the electronic pen management screen 70 is a usability display unit that displays the usability information and the status information R together.
On the electronic pen management screen 70, a setting execution button 72 and a setting cancel button 73 are also displayed.
The registration button 71 identifies any of the electronic pens 13A, 13B, and 13C based on the identification information Q in a registration step described later, and positions information (x _A , y _A ), (x _B , y _B ). , (X _C , y _C ) are registered in a usable state that can be generated.
In addition to these pieces of information, unique information such as identification information Q of the electronic pen 13 may be displayed. Further, only a part of the discrimination information, the status information R, and the availability information may be displayed.

On the electronic pen management screen 70, the user touches or sets the electronic pen 13 in a usable state on the setting information column of each electronic pen 13, thereby making it possible to discriminate information and state information R during writing. The shape, color, size, etc. of the line are changed (step S203).
When the set change is correct, the user presses the setting execution button 72 to confirm the setting change. Similarly, when there is an error, the setting cancel button 73 is pressed to cancel the setting change.
Since the setting execution button 72 and the setting cancel button 73 are thus provided, the setting can be determined according to the intention of the user, so that a setting change due to an erroneous operation is prevented.

The electronic blackboard 10 checks whether the setting changed in step S203 can be set (step S204).
When it is determined in step S204 that the setting is impossible, the electronic pen management unit 18 discards the setting change, and the electronic blackboard 10 displays the error content on the display surface 11 (step S205). Return to 70.
If it is determined in step S204 that setting is possible, the electronic pen management unit 18 reflects the setting of the electronic pen 13 in the electronic pen management table shown in FIG. 2 (step S206).

  In addition, the user performs a pairing operation for registering the electronic pen 13 on the electronic blackboard 10 on the condition that the registration button 71 as the registration unit is pressed on the electronic pen management screen 70 (step S207). .

A pairing operation when registering the electronic pen 13 on the electronic blackboard 10 will be described. FIG. 12 is a registration information input screen when performing a pairing operation, and items for registering the electronic pen 13 in the electronic blackboard 10 are illustrated.
Note that the pairing operation in step S207 is a registration for setting the electronic pen 13 to the electronic blackboard 10 and setting the position information (x, y) in a usable state, as will be described later. It is a step.

  Here, a case where an unregistered electronic pen 13C is registered with respect to the registered electronic pens 13A and 13B will be described as an example. The electronic pens 13A and 13B have already been registered, and a pairing operation as described below has been performed.

When the registration button 71 arranged in the column of the electronic pen 13C is pressed on the electronic pen management screen 70, the electronic blackboard 10 transitions to a new registration screen 90 of the electronic pen 13C as shown in FIG.
The user arbitrarily sets setting information such as a discrimination name used as discrimination information of the electronic pen 13C and a shape, size, and color of a trajectory used as visual characteristic information.
In the new registration screen 90, it is desirable that the identification information Q of the electronic pen 13C is automatically acquired by the electronic pen management unit 18 via the communication unit 30 and displayed.
Thus, by automatically acquiring the identification information Q, erroneous operation by the user is reduced, and the identification information Q without duplication is easily set.

In the new registration screen 90, it is desirable that the electronic blackboard 10 does not accept input by the electronic pens 13A and 13B other than the display of the identification information Q, or input by a finger or the like.
In this way, in the new registration screen 90, the electronic blackboard 10 allows input only to the specific electronic pen 13C on which the identification information Q is displayed, thereby preventing the user from mistakenly using the electronic pen 13C and preventing erroneous operation. Or suppressed.

When the user inputs all information described in the new registration screen 90, the user presses the setting execution button 72 to confirm the setting.
When the setting execution button 72 is pressed, the electronic blackboard 10 checks whether the changed setting can be set as in step S204.
When it is determined that setting is possible as in step S206, the electronic pen management unit 18 reflects the new setting of the electronic pen 13C in the electronic pen management table.
Thus, by changing the setting in the registration step, the electronic pen 13C rewrites the state information R into a usable state.
If the electronic pen 13C is communicating with another electronic device or the power is not turned on, an error is displayed as in step S205, and the setting change is discarded.

An electronic blackboard system 500 shown in the present embodiment generates an electronic blackboard 10 that displays the visual information S on the display surface 11 and position information (x, y) on the display surface 11 in contact with the display surface 11. And an electronic pen 13.

It has the communication part 30 which is a communication means.
The electronic blackboard 10 identifies a plurality of electronic pens 13A, 13B, and 13C based on the identification information Q, and a registration button 71 that sets the position information (x, y) to a usable state that can be generated, and a registration button 71 The electronic pen management screen 70 that distinguishes and displays the electronic pens 13A and 13B that have become usable by the electronic pen 13C and the electronic pen 13C that has not been usable.
With this configuration, usable combinations at the time of pairing are easily determined.

The electronic pen management screen 70 displays status information R of the electronic pen 13 along with the availability information of the plurality of electronic pens 13.
With this configuration, usable combinations at the time of pairing can be easily determined, and the shape of the trajectory when used on the same screen can be managed, which improves convenience for the user.

The electronic pen management screen 70 displays the identification information Q of the electronic pen 13 together with the availability information of the electronic pen 13.
With this configuration, the electronic pen 13 can be uniquely identified, so that a usable combination at the time of pairing can be easily determined. Further, since the identification information Q is unique to each electronic pen 13, there is no duplication.

In the present embodiment, the state information R includes at least one information among the color, size, and shape when displaying the locus where the electronic pen 13 contacts the electronic blackboard 10.
With this configuration, when a writing operation is performed using the electronic pen 13, the user can easily predict the trajectory, so that convenience for the user is improved.

In the present embodiment, the electronic blackboard system 500 includes a position information acquisition step S303 for generating position information (x, y) on the display surface 11 of the pointing device in contact with the display surface 11 of the electronic blackboard 10. ing.
The electronic blackboard system 500 also includes an identification information acquisition step S104 for acquiring the identification information Q of the electronic pen 13.
