  In the electronic conference system of Patent Document 1 described above, since it is necessary to prepare as many small clients with display screens as the number of participants in each conference, the number of clients increases as the number of participants increases. It may be difficult to have a client for everyone.

  The present invention has been made in view of the above circumstances, and by displaying one display touch panel in a divided manner according to the position and number of the user, and enabling reference and editing of display data in the divided display area. An object of the present invention is to provide a display control device and a display control program that enable a conference by a plurality of users to be performed using only one display touch panel.

In order to solve the above-described problem, a first technical means of the present invention is a display control device that performs display control of a display touch panel in which a display device and a touch panel are integrated, and is a user connected to the display control device. User recognition means for recognizing the position and number of users around the display touch panel based on an input signal from the position sensor, and the display area of the display touch panel corresponding to the user position based on the recognition result by the user recognition means Display area determining means for determining the divided display area, and specific position determining means for determining whether or not the position of the user recognized by the user recognizing means is within a predetermined specific range. The unit recognizes the size of the display area corresponding to the user within the specific range determined by the specific position determination unit. Set the number to relationship without certain size of The, the size of the other display area except the display area corresponding to the user within a specific range, be determined according to the number of users other than the users in a specific range It is characterized by.

The second technical means includes display screen generating means for generating a display screen for the display area determined by the display area determining means in the first technical means, and the display screen generating means is determined by the display area determining means. Among the determined display areas, the display state of the display area corresponding to the user within the specific range determined by the specific position determining means, and the display state of other display areas excluding the display area corresponding to the user within the specific range It is characterized by different.

  A third technical means is the second technical means for a file displayed in each display area between a display area corresponding to a user within a specific range and a display area corresponding to a user outside the specific range. It is characterized by changing the operation authority.

  As a fourth technical means, in the third technical means, as one of the operation authority of the display area corresponding to the user within the specific range, a drag operation is performed in a specific direction with respect to the file displayed in the display area. When set, an authority to display a file in which a drag operation is performed on another display area in a specific direction is set.

  The fifth technical means includes means for enabling reception of image data sent from the image processing apparatus via the network in the second technical means, and the display screen generating means is sent from the image processing apparatus. The image data is displayed in a display area corresponding to a user within a specific range.

According to a sixth technical means, in the first technical means, the display area determining means corresponds to a user within a specific range in the display area corresponding to each user as the number of users recognized by the user recognizing means increases. This is characterized in that the size of the display area other than the display area is reduced.

According to a seventh technical means, in the first technical means, the display area determining means is a user within a specific range of the display areas corresponding to each user as the interval between the positions of the users recognized by the user recognizing means becomes smaller. The display area other than the display area corresponding to is reduced in size.

  The eighth technical means is a display control program for realizing the function of the display control apparatus which is one of the first to seventh technical means.

  According to the present invention, a single display touch panel is divided and displayed according to the position and number of users, and the display data of the divided display areas can be referred to and edited, so that a plurality of display touch panels can be used. It is possible to provide a display control device and a display control program that enable efficient user conferences.

  In particular, according to the present invention, when the display touch panel is used by a plurality of users, the entire display area of the display touch panel is divided into an appropriate size for each user according to the position and the number of users. The display area can be displayed at an appropriate position. Also, so that all users can be displayed at this time, the size of the display area per person decreases as the number of users increases or as the user interval decreases, making it optimal according to the number of users and the position. It becomes possible to set an appropriate split display area.

  Further, according to the present invention, when the display touch panel is used in a conference, the display state of the conference facilitator can be made different from the display status of other participants. Other participants are only allowed to view the conference material using the display area, while the facilitator of the conference is given the operating authority to read and write the conference material. Thus, specific operation authority can be used properly according to the user. The facilitator of the conference can distribute conference materials to specific participants with a simple operation. Furthermore, the image data read by the scanner can be displayed only in the display area of the meeting facilitator. As a result, the conference can be efficiently performed without causing confusion with display data such as conference materials.

FIG. 1 is a block diagram for explaining an embodiment of a display control apparatus according to the present invention.
In this example, a configuration example will be described in which the display screen of the large display touch panel is horizontally installed with the display screen facing upward and used as a conference desk.
The display control apparatus 100 includes a communication I / F 120 and can perform display control of the large display touch panel by connecting to the communication I / F 202 of the large display touch panel 200. The large display touch panel 200 is configured by integrating a display device such as a large liquid crystal panel and a touch panel, for example. A predetermined operation signal can be transmitted to the display control device 100 by the user operating the touch panel according to the display on the display device.

  The large display touch panel 200 includes a user position sensor 201, detects a user, and transmits a detection signal to the display control device 100. The large display touch panel is used as a conference desk by placing it horizontally with the display screen facing upward as described above. At this time, the user position sensor 201 is provided to detect the position and number of users sitting around the large display touch panel. A plurality of user position sensors 201 are provided, for example, around the frame of the large display touch panel 200, and can detect a user sitting around the large display touch panel installed horizontally.

  As the user position sensor 201, an infrared sensor can be preferably used, but the sensor system is not limited. Moreover, although the user position sensor 201 is suitably provided in the position which can detect the user around the large sized display touch panel 200 as mentioned above, the position and number are not limited. For example, when a meeting participant sits around the large-sized display touch panel 200, when the position of the participant is almost determined, the user position sensor 201 can be installed at each of the positions. When there is a possibility that the user may sit at random, a plurality of user position sensors 201 are continuously arranged at a predetermined interval, and the position and number of users can be determined based on the detection signal of each user position sensor 201. You may do it. Further, the installation position of the user position sensor 201 may be variably set.

  In this example, a configuration in which the user position sensor 201 is arranged so as to detect a user around the large display touch panel 200 installed horizontally and used as a conference desk will be described. In addition, a large display touch panel installed vertically is described. The user position sensor 201 may be arranged so as to detect the position and number of users operable with respect to 200, and display control based on the position information may be performed.

The display control device 100 generates a display screen to be displayed on the large display touch panel 200 and performs processing based on a touch operation on the large display touch panel 200.
The display control apparatus 100 includes a communication I / F 120 for performing communication with the large display touch panel 200, a control unit 110 for performing control of each unit of the display control apparatus 100, and display control of the large display touch panel 200, and a large display. An image including a storage unit 130 for storing various data and programs including document data and user attribute information to be displayed on the touch panel 200, and other external devices such as a scanner unit 301 and a printing unit 302 via a network. And a network I / F 140 for connecting to the processing apparatus 300.
The display control device 100 can be configured to be built in a computer device such as a PC, or can be configured as a single device.

  The control unit 110 includes a user recognition unit 111 that recognizes the position and number of users who are participants in the conference based on a user detection signal output from the user position sensor 201 of the large-sized display touch panel 200. . The user position sensor 201 detects a user around the large display touch panel 200 and outputs a detection signal to the display control device 100. Thereby, in the display control apparatus 100, the conference participant when using the large display touch panel 102 as a conference desk can be recognized.

  The control unit 110 further includes a display area determination unit 112 that determines a display area for dividing and displaying the display area of the large-sized display touch panel 200 based on the user position and the number of users recognized by the user recognition unit 111. And a display screen generation unit 113 that generates a display screen for the display area determined by the display area determination unit 112.

  The display area determining unit 112 determines to divide the display area of the large display touch panel 200 according to the user position and the number of users recognized by the user recognizing unit 111, and the display screen generating unit 113 determines the determined display area. The display area of the large-size display touch panel 200 is divided to control the screen display.

  For example, if there are four recognized users, the display area for each user is displayed by dividing the entire display area of the large display touch panel 200 into four. At this time, the display area of each user is displayed at a position corresponding to the position of each user, that is, a position in front of the user recognized by the user recognition unit 111. Then, the display direction of the display screen in the display area is set so as to be an appropriate display direction when viewed from the user. Here, when the large-sized display touch panel 200 is rectangular, the display in the display area can be visually recognized from any of the four surrounding sides.

In this case, the display state of the display area may be changed based on the recognition result by the user recognition unit 111.
For example, the user recognition unit 111 determines whether the user is a meeting facilitator or a participant other than the facilitator based on the user recognition result by the user position sensor 201, and corresponds to the facilitator. The display area and the display area corresponding to another participant may be determined to have different sizes.
For example, since the facilitator of the conference needs to operate and edit more conference materials than the other participants, it can display differently from the other participants. For example, the facilitator display area may be set at a specific size at a specific position in the full-screen display area, and other areas may be divided according to the number and positions of participants.

  The facilitator and other participants of the conference can be discriminated by the user's recognition position by the user position sensor 201. That is, a specific range in which the facilitator should sit is determined in advance, and when a user within the specific range is recognized, it is determined that the facilitator is a conference facilitator. When a user is recognized in a range other than the specific range, it is determined that the user is another participant who is not a facilitator.

  The display screen generator 113 includes a facilitator display screen generator 113a that displays a facilitator display area and a participant display screen generator 113b that displays a display area for other participants. Yes. In the display screen generation unit 113, the display screen for the facilitator is displayed by the display screen generation unit 113a for the facilitator according to the display area recognized by the user recognition unit 111 and determined by the display area determination unit 112. For the display area for other participants, a display screen is generated by the participant display screen generation unit 113b and displayed on the large display touch panel 200.

  And the control part 110 has the facilitator input operation recognition part 114 which recognizes input operation of the facilitator of a meeting, and the participant input operation recognition part 115 which recognizes input operation of participants other than a facilitator. ing. These determine whether the input operation on the large display touch panel 200 is an input operation by a facilitator or an input operation by another participant.

  And when displaying the display area for facilitator and the display area for other participants, the size of these display areas is different as described above, or the size and position of the display area for facilitator are changed. It can be fixed and other display areas can be divided according to the position and number of participants.

In addition, as a process of changing the display state of the display area for facilitator and the display area for other participants, the operation authority for the display area for facilitator can be made different.
For example, document data such as conference material can be captured by the scanner unit 301 of the image processing apparatus 300, and the file of the document data can be displayed only in the display area for the facilitator. Also, document data files such as conference materials created on a PC or the like can be displayed only in the display area for facilitators.

  In the facilitator display area, as the special operation authority for the displayed files such as conference materials, the operation authority to display the file displayed in the facilitator display area also in the participant display area. Can be granted. Here, for example, by performing a predetermined operation such as a drag operation on a file such as a conference material displayed in the display area for the facilitator, the facilitator is displayed on another display area in the drag direction. The same file as the meeting material displayed in the display area can be displayed.

The operation authority for the display area for facilitator can be given not only the display control authority by the drag operation as described above, but also the file operation authority that enables the file to be saved or modified. At this time, file operations such as editing performed on the display area for facilitators can be reflected in the file displayed in the display area for participants.
In this way, the authority that can be executed by the operation on the display area for facilitator and the authority that can be executed by the operation on the display area for other participants can be made different.

Further, an operation authority different from that for other display areas may be given to a specific display area among the display areas for the participants.
For example, with respect to a display area for a specific participant, file editing authority and operation authority such as file saving / deleting can be given. Thereby, for example, the person in charge who creates the minutes among the participants can add or correct the displayed file or save the file.

  Also in this case, similarly to the recognition of the facilitator, the user who operates the display area to which the specific operation authority is given can be determined by the user recognition position by the user position sensor 201. That is, a specific range corresponding to a display area to which a specific operation authority is given is determined in advance, and when a user within the specific range is recognized, the specific operation authority is given to the display area for the user. be able to. The operation authority at this time can be set separately from the operation authority for the display area for facilitator.

On the other hand, the meeting facilitator and other participants may be discriminated from the ID or password identification information input by the user. When the user is recognized by the user recognition unit 111, the display screen generation unit 113 displays a predetermined login screen in the display area for the user, and requests the user to input identification information. The identification information may be, for example, the ID and password as described above, or may be only the ID.
The user recognition unit 111 authenticates the identification information input by the user. If the authentication is successful, the user recognition unit 111 permits the user to log in, and enables operation input to the display area for the user.

  The identification information of the user who can log in can be set in advance by, for example, a meeting facilitator. Thereby, the participant who participates in a meeting can be registered into the display control apparatus 100 previously. At this time, information indicating whether the user is a conference facilitator or another participant is associated with user identification information and registered as user attribute information. The user attribute information is stored in the user attribute storage unit 132 of the storage unit 130.

  When the identification information is input by a user registered as a conference participant, the user recognition unit 111 refers to the user attribute storage unit 132 and permits the user to log in. Further, it is determined from the user attribute information whether the user is a meeting facilitator or another participant. Thereby, as described above, it is possible to perform control to change the display state of the display area between the facilitator and the participant or to change the operation authority.

  Further, as in the above-described example, even when a different operation authority is given to a specific display area among the display areas for the participants, the specific display area is determined based on the user attribute information. It is possible to determine that the user is to be given the operation authority, and to give a specific operation authority such as file editing authority and file saving / deletion to the display area corresponding to the user.

  The control unit 110 of the display control apparatus 100 further includes a document data management unit 116 that manages document data, and a print data generation unit 117 that generates print data. The document data management unit 116 manages document data to be displayed on the large display touch panel 200. The document data includes, for example, document data read by the scanner unit 301 of the image processing apparatus 300, document data created by a PC or the like and input to the display control apparatus 100, and these are stored in the document data storage of the storage unit 130. Stored and held in the unit 131. The document data read by the scanner unit 301 is stored and held as image data.

  The document data management unit 116 reads a specific document data file from the document data storage unit 131 in response to the recognition of the input operation by the facilitator input operation recognition unit 114 and the participant input operation recognition unit 115, and generates a display screen. By generating the file display screen by the unit 113, the document data file can be displayed on the large display touch panel 200. The displayed document data file can be stored and saved in the document data storage unit 131.

  The print data generation unit 117 is a printer driver, for example. The print data generation unit 117 acquires a document data file edited during a meeting or the like using the large display touch panel 200, generates print data for the printer, and stores it in the image processing apparatus 300. It can be transmitted and printed out by the printing unit 302 of the image processing apparatus 300. Further, the print data generation unit 117 can appropriately generate print data from the document data file stored in the document data storage unit 131, transmit it to the image processing apparatus 300, and print it out.

FIG. 2 is a diagram showing a display example of a large-sized display touch panel whose display is controlled by the display control apparatus according to the present invention. The large display touch panel 200 can be used as a conference desk by installing it horizontally with the display screen facing upward as described above.
The large display touch panel 200 is connected to a display control device 100 (not shown in FIG. 2). The display control apparatus 100 can recognize the number of users and the position by a user position sensor 201 (not shown in FIG. 2) provided on the large display touch panel 200. Then, the display control apparatus 100 divides the display area of the large display touch panel 200 into a plurality of display areas and displays them according to the recognized number and positions of users.

  In the example of FIG. 2, it is assumed that a total of five users seated in the conference facilitating seat 11 and the four participant seats 12 a to 12 d are recognized based on the detection result by the user position sensor 201. In this case, the entire display area of the large display touch panel 200 is divided into five according to the recognized number of users and positions. The divided display areas are a display area 21 for a facilitator and display areas 22a to 22c for other participants.

  Each of the display areas 21 and 22a to 22d is displayed at a position corresponding to the position of the user, that is, a position in front of the user recognized by the user recognition unit 111 of the display control device 100. And the display direction of the display screen in a display area is set so that it may become an appropriate display direction when it sees from a user. Thus, for example, when a file such as a conference material is displayed in the display area, the conference material is controlled to be displayed in an appropriate direction as viewed from the user. Here, the large display touch panel 200 has a rectangular shape, and the display in the display area can be visually recognized from any of the four surrounding sides.

  In the example of FIG. 2, the display area 21 for facilitator is set at one end of the large display touch panel 200 and the size of the display area 21 is set in advance. The remaining display areas are equally divided according to the four participants and set as display areas 22a to 22d for the participants. Thus, the display area 21 for facilitator and the display areas 22a to 22d for other participants can be set to have different sizes. The facilitator and the participant can be discriminated from the recognized user position, or can be discriminated from the user identification information input on the login screen.

FIG. 3 is a diagram showing another display example of a large-sized display touch panel whose display is controlled by the display control apparatus according to the present invention. In the example of FIG. 2, there are four participants in addition to the facilitator. However, in the example of FIG. 3, there are two participants in the facilitator.
In this case, a total of three users seated in the conference facilitating seat 11 and the two participant seats 12 a and 12 b are recognized based on the detection result by the user position sensor 201. In this case, the display area of the large display touch panel 200 is divided according to the recognized number and positions of users. The divided display areas are a display area 21 for a facilitator and display areas 22a, 22b, 22c, and 22d for other participants. Here again, the display area 21 for the facilitator can be set in a predetermined position at a predetermined size in advance.

  In this example, the display area for participants is divided into four, but there are actually two participants recognized by the user position sensor 201. In this case, the display areas 22a and 22b corresponding to the participant seats 12a and 12b are displayed in a large size, and the display areas 22c and 22d for other participants are displayed in a small size.

  With respect to at least a part of the display area for each user (display area excluding the display area for facilitator) determined by the display area determination unit 112 by the processing as described above, the size of the display area is determined by user recognition. As the number of users recognized by the unit 111 increases, the number decreases. Further, for at least a part of the display area, the size of the display area for each user becomes smaller as the interval between the positions of the users recognized by the user recognition unit 111 becomes smaller. That is, the display area to be divided according to the recognized user position and number can be set to be in an optimal state. In this case, the size of the display area for facilitators may be reduced as the number of users increases or the interval between users decreases as in the display areas for other participants.

FIG. 4 is a diagram for explaining an example of the operation authority given to the display area for facilitator. As described above, in the display control apparatus according to the present embodiment, a specific operation authority can be given to the display area 21 for a facilitator.
For example, as shown in FIG. 4A, a drag operation can be performed on a document data file 23 such as conference material displayed in the display area 21 for facilitator. The drag operation is an operation on the touch panel by the hand of the facilitator. The display position of the file 23 displayed in the display area 21 for facilitator is slid according to the drag operation.

As shown in FIG. 4B, when the file 23 displayed by the drag operation moves more than a predetermined distance, the display area for the other participants in the drag direction (the display area 22c in this example) is displayed. The file 24 of the same document data as the file 23 displayed in the display area 21 for facilitator can be displayed. When the drag operation is finished, the file 23 is returned to the original position and displayed in the display area 21 for facilitator.
In this way, the facilitator of the conference can distribute files such as conference materials to specific participants by a simple operation such as a drag operation. The authority for such a distribution operation can be given only to the display area for facilitators.

FIG. 5 is a flowchart for explaining an example of the display control process in the display control apparatus according to the present invention.
First, the display control device recognizes the position of the user based on the input signal from the user position sensor (step S1), and determines the display area of the conference participants according to the number of recognized users (step S2). Next, a login screen is displayed in the display area of the newly recognized participant (step S3). Then, authentication is performed with the login ID and password input by the newly recognized participant (step S4).

  If the user is newly recognized (step S5-YES), the process returns to step S1 to recognize the position of the new user. If a new user is not recognized (step S5-NO), it is further determined whether or not there is an operation input for the large display touch panel (step S6). If there is an operation input, the input person (facilitator or each participant) is recognized from the display area of the input position (step S7). Here, it is determined whether the operation input is performed on the display area for facilitators or on the display area for other participants, and the input person Recognize whether you are a facilitator or another participant.

Then, it is determined whether or not the operation input is a facilitator's operation (step S8), and if it is a facilitator's operation, processing related to the facilitator operation is executed (step S12). A processing example related to the facilitator operation will be described later. If the operation is not a facilitator operation, it is further determined whether the operation is a participant operation (step S9). If the operation is a participant operation, processing related to the participant operation is executed (step S13). Processing examples related to participant operations will also be described later.
If it is not a participant operation input in step S9, the process returns to step S1.

  If there is no operation input in step S6, it is determined whether a scanned image has been received (step S10). A scanned image is read from a document by a scanner of an image processing device connected to the display control device, for example, and transmitted as image data to the display control device. Here, if the display control device has received the scan image, the scan image is displayed in the display area of the facilitator (step S11), and the process returns to step S1. In addition, when the scan image is not received in step S10, the process returns to step S1.

  FIG. 6 is a flowchart for explaining an example of processing related to the facilitator operation, and shows a processing example when the input operation to the large display touch panel is an operation by the facilitator. Here, first, it is determined whether or not the operation by the facilitator is an operation of reading a display file (step S21). The display file is, for example, a document data file stored in the document data storage of the display control device. If the operation is to read the display file, the file is read according to this operation and displayed in the display area for the facilitator (step S26).

  If the operation by the facilitator is not an operation for reading the display file, it is next determined whether or not the operation is to distribute the file to all participants (step S22). The operation for distributing the file is, for example, a drag operation on the fill as described above. Alternatively, an operation for displaying a predetermined menu and selecting a file distribution process may be used. If the operation is to distribute a file, the distribution file is displayed in the display area for each participant (step S27).

  If the operation by the facilitator is not an operation for distributing a file to all participants, it is next determined whether or not the operation is a file distributing operation for a specific participant (step S23). Also in this case, as the file distribution operation, a drag operation, a menu operation, or the like can be determined in advance. If it is a file distribution operation for a specific participant, the distribution file is displayed in the participant display area designated by the facilitator (step S28).

  If the operation by the facilitator is not a file distribution operation for a specific participant, it is next determined whether or not the operation is a file operation (step S24). The file operation refers to an editing operation by writing or correcting the display file. If it is a file operation, the file display in the display area for each participant is changed in conjunction with the file operation of the facilitator (step S29).

  If the operation by the facilitator is not a file operation, it is next determined whether or not it is a print instruction for the designated file (step S25). If it is a print instruction, the designated file designated by the facilitator is printed out to an image processing apparatus or the like having a printing function (step S30).

  FIG. 7 is a flowchart for explaining an example of processing related to the participant role operation, and shows an example of processing when the input operation to the large display touch panel is an operation by a conference participant (other than the facilitator). . Here, first, the display processing apparatus checks the operation authority of the input person (step S31). Checking the operation authority of the input user is a process of confirming whether the input user has the operation authority to perform a specific file operation such as file editing. Such operation authority of the input person is given to a specific user in advance, and the operation authority can be determined based on the identification information (ID, password, etc.) of the input person input at the time of login.

If the input user has a specific operation authority such as file editing (step S32-YES), the specific file operation is performed according to the input user's operation (step S33). Further, a process for saving the file after the operation as an input user file is performed (step S34). Only one of these file operations and the storage process may be performed, or may be performed separately at different timings.
Further, if the input person does not have the operation authority in step S32, a predetermined warning display is displayed in the display area of the input person (step S35).

The display control program according to the present invention is a program for controlling a CPU or the like (a program for causing a computer to function) so that the functions of the display control apparatus 100 can be realized.
Here, the function of each unit of the control unit 110 shown in FIG. 1, that is, the user recognition unit 111, the display area determination unit 112, the display screen generation unit 113, the facilitator input operation recognition unit 114, the participant input operation recognition unit 115, the document A program that causes a computer to realize the functions of the data management unit 116, the print data generation unit 117, and the like is stored in the storage unit 130 or other predetermined storage unit, and an arithmetic unit such as a CPU included in the control unit 110 executes the program. By reading and executing, it is possible to execute the display control process of the large display touch panel according to the above embodiment.

Further, by executing the read program, not only the functions of the above-described embodiments are realized, but also the present invention is processed by jointly processing with the operating system or other application programs based on the instructions of the program. In some cases, the functions of the related embodiments are realized.
