  Hereinafter, preferred embodiments according to an information display apparatus of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram showing an example of the appearance of an information display device according to an embodiment of the present invention. In the figure, 1 to 4 are portable terminals, and 5 is an information display device. In this example, a smart phone is illustrated as the mobile terminals 1 to 4, and an information display table (hereinafter, information display table 5) is illustrated as the information display device 5. The information display table 5 has a display screen incorporated on the top of the table and has an information processing function similar to that of a PC (Personal Computer). The information display table 5 can be used by dividing one display screen into a plurality of areas.

  This information display table 5 sets, for example, a dedicated area for each person when a plurality of people gather and make individual reports, and displays necessary data as if it were a dedicated PC. Switch between the dedicated area mode that can be operated and the large screen mode that allows the necessary data to be displayed and operated on one large screen when everyone discusses one agenda. Can be set.

  In the case of this example, for the four users who use the portable terminals 1 to 4, the large screen of the information display table 5 is divided into four areas, dedicated areas 5a to 5d. Each of these dedicated areas 5a to 5d is provided with a separate arithmetic unit, and information processing can be performed independently for each dedicated area. Note that the number of divisions of the area is not limited to four. For example, if the number of users is two, flexible area division is possible, such as division into two.

  And the information display table 5 acquires the specific information of the portable terminals 1 to 4 when the portable terminals 1 to 4 are close to the screen, and includes the coordinates on the screen that the portable terminals 1 to 4 are in contact with or the coordinates thereof. The area can be detected, and data can be transmitted / received to / from the mobile terminals 1 to 4 according to the coordinates or the area associated with the unique information of the mobile terminals 1 to 4. In the example of FIG. 1, the coordinate touched by the mobile terminal 1 is (x1, y1). As described above, the simple operation of simply bringing the mobile terminals 1 to 4 into contact with the screen facilitates the cooperation with the mobile terminals 1 to 4 and allows data communication to be easily performed.

  FIG. 2 is a block diagram illustrating a configuration example of the mobile terminal and the information display table illustrated in FIG. In this example, only the portable terminal 1 is illustrated, but the other portable terminals 2 to 4 have the same configuration. The mobile terminal 1 is close to the information display table 1 between the CPU 11 that controls the operation of the mobile terminal 1, the storage unit 12 that stores various data, the acceleration sensor 13 that detects the movement of the mobile terminal 1, and the information display table 1. And a wireless communication unit 14 that performs distance wireless communication. In addition, the information display table 5 is for the CPU 51 that controls the operation of the information display table 5, the coordinate detection unit 52 that detects the coordinate position on the screen, the storage unit 53 that stores various data, and the display unit 57. A display driver 54 that performs display control, a wireless communication unit 55 that performs short-range wireless communication with the mobile terminal 1, a touch panel 56 that is provided integrally with the display unit 57, and a display unit 57 such as a liquid crystal display. It has.

  Here, as a specific example of short-range wireless communication, the above-described TransferJet (registered trademark) can be cited. When the information display table 5 and the portable terminal 1 are close to about several centimeters, a connection is established according to a predetermined communication protocol and communication is possible. At this time, the wireless communication unit 14 of the mobile terminal 1 transmits a MAC (Media Access Control) address as an example of the unique information of the mobile terminal 1, and the wireless communication unit 55 of the information display table 5 is transmitted from the mobile terminal 1. Received MAC address. The wireless communication unit 55 of the information display table 5 transmits the MAC address of the information display table 5, and the wireless communication unit 14 of the mobile terminal 1 receives the MAC address transmitted from the information display table 5. By exchanging MAC addresses with each other in this way, data communication can be performed between the portable terminal 1 and the information display table 5.

  In addition, the display unit 57 is configured integrally with a touch panel 56 that enables a touch operation, and the coordinate detection unit 52 is a contact point via the touch panel 56 when the mobile terminal 1 touches the screen of the display unit 57. It is comprised so that the coordinate of may be detected. The touch panel 56 supports multi-touch input and can receive simultaneous operations by a plurality of people.

  Further, the CPU 51 determines whether or not the timing at which the acceleration sensor 13 of the mobile terminal 1 reacts and the timing at which the touch panel 56 reacts simultaneously with the coordinate detection of the contact point by the touch panel 56. The acceleration sensor 13 reacts when the mobile terminal 1 comes into contact with the screen of the display unit 57. A timing signal at the time of this reaction is input to the CPU 51 by the wireless communication unit 55. And CPU51 determines with the portable terminal 1 contacting on the screen of the display part 57, when both reaction timing corresponds.

  A main object of the present invention is to facilitate cooperation with a mobile terminal and easily perform data communication by a simple operation of simply bringing the mobile terminal into contact with a screen. As a configuration for this, the information display table 5 acquires the unique information of the mobile terminal 1 when the mobile terminal 1 comes close to the screen of the display part 57 and the display part 57 that can divide one screen into a plurality of areas. Specific information acquisition unit, a coordinate detection unit 52 that detects a coordinate on the screen of the display unit 57 touched by the mobile terminal 1 or a region including the coordinates, and the specific information of the mobile terminal 1 acquired by the specific information acquisition unit The unique information associating unit for associating with the coordinates or the area including the coordinates detected by the detecting unit 52 and the area including the coordinates or the coordinates associated with the unique information of the mobile terminal 1 are wirelessly transmitted between the mobile terminal 1 and the mobile terminal 1. And a data communication unit for performing data communication via the network.

  Here, in the example of FIGS. 1 and 2, the area is an area including coordinates (x1, y1), and the coordinates (x1, y1) are included in the dedicated area 5a in FIG. The region 5a may be the target. Alternatively, for example, an area of 10 pixels around the coordinates (x1, y1) may be targeted. That is, if the region includes coordinates (x1, y1), the range of the region can be set as appropriate.

  In FIG. 2, the functions as the unique information acquisition unit and the data communication unit are realized by the wireless communication unit 55, and the function as the unique information association unit is realized by the CPU 51. When the mobile terminal 1 contacts the coordinates (x1, y1) on the screen, the unique information of the mobile terminal 1 is associated with an area including the contact coordinates (x1, y1) or the coordinates (x1, y1). At this time, if data is displayed in the area including the contact coordinates (x1, y1) or the coordinates (x1, y1), the wireless communication unit 55 wirelessly transmits display data or related data of the display data to the mobile terminal 1. Send through. For example, when a plurality of image data is displayed in the information display table 5, image data corresponding to the contact coordinates (x1, y1) is selectively transmitted to the mobile terminal 1. When map data is displayed in the information display table 5, the position information (longitude, latitude) corresponding to the contact coordinates (x1, y1) is selectively selected as related data of the displayed map data. It can be transmitted to the mobile terminal 1.

  In addition, if data is not displayed in the area including the contact coordinates (x1, y1) or the coordinates (x1, y1) associated with the unique information of the mobile terminal 1, the wireless communication unit 55 receives from the mobile terminal 1. The data is received via wireless, and the display unit 57 displays the data received by the wireless communication unit 55 in an area including coordinates (x1, y1) or coordinates (x1, y1). When data is transferred from the portable terminal 1 to the information display table 5, for example, the data to be transferred can be flicked. The data transmission / reception starts after the association between the mobile terminal 1 and the contact coordinates (x1, y1) is completed. After the association is completed, the user can determine whether the data transmission / reception may be performed. You may make it display the confirmation screen for confirming to the portable terminal 1 or the information display table 5. FIG.

  The region including the coordinates (x1, y1) or the coordinates (x1, y1) associated with the unique information of the mobile terminal 1 may change. In the example of FIG. 1, when the number of attendees such as a meeting is changed, the allocation of the dedicated areas 5a to 5d is changed. As a result, coordinates (x1, y1) may change to coordinates (x2, y2). In such a case, the CPU 51 may associate the unique information of the mobile terminal 1 with the area including the coordinate (x2, y2) or the coordinate (x2, y2) after the change. Thereby, even when the coordinate or area | region which matched the portable terminal 1 changes, since a correlation with the portable terminal 1 can be continued following the change of a coordinate or area | region, a coordinate or area | region changes. There is no need to associate with the mobile terminal 1 each time.

  Here, the storage unit 53 of the information display table 5 stores association information in which the unique information of the mobile terminal 1 is associated with the area including the coordinates (x1, y1) or the coordinates (x1, y1). Thus, even after the mobile terminal 1 is separated from the region including the coordinates (x1, y1) or the coordinates (x1, y1), the unique information of the mobile terminal 1 and the coordinates (x1, y1) or the coordinates (x1, y1) The association with the area including y1) is maintained. That is, when the mobile terminal 1 is brought into contact with the coordinates (x1, y1) on the screen once and then separated from the screen, and the mobile terminal 1 is again brought close to the screen, the information display table 5 is displayed on the unique information of the mobile terminal 1. To get. At this time, since the association information of the portable terminal 1 is stored in the storage unit 53, the information display table 5 is displayed in accordance with the area including the coordinates (x1, y1) or the coordinates (x1, y1) on the screen. Data communication can be performed with the mobile terminal 1.

  In the above, when the association information is stored in the storage unit 53, that is, the association between the unique information of the mobile terminal 1 and the area including the coordinates (x1, y1) or the coordinates (x1, y1) is maintained. If there is, the CPU 51 prohibits the association between the coordinates (x1, y1) or the region including the coordinates (x1, y1) and another portable terminal other than the portable terminal 1. In this case, even if another portable terminal outside the portable terminal 1 is brought into contact with the region including the coordinates (x1, y1) or the coordinates (x1, y1), the other portable terminals are not coordinated (x1, y1) or coordinates ( Since it cannot be associated with an area including x1, y1), data communication cannot be performed with another mobile terminal according to the area including coordinates (x1, y1) or coordinates (x1, y1).

  When a predetermined operation on the information display table 5 is detected, the CPU 51 deletes the association information from the storage unit 53, and the unique information and coordinates (x1, y1) or coordinates (x1, y1) of the mobile terminal 1 You may make it cancel matching with the area | region containing. Specifically, as the predetermined operation, for example, an operation such as turning off the power of the information display table 5 or bringing the mobile terminal 1 into contact with a predetermined area provided on the screen of the information display table 5 is performed. By doing so, the association between the coordinates (x1, y1) or the region including the coordinates (x1, y1) and the mobile terminal 1 can be canceled.

  FIG. 3 is a block diagram showing another configuration example of the mobile terminal and the information display table according to the present invention. In this example, an example in which a headset 6 is applied instead of the mobile terminal 1 of FIG. 2 as a mobile terminal that associates coordinates on the screen or a region including the coordinates will be described. Since the configuration of the information display table 5 is the same as that in the example of FIG. 2, repeated description is omitted. The headset 6 is a headphone that outputs audio based on audio data and multimedia data (video and audio) reproduced in the information display table 5, and stores a CPU 61 that controls the operation of the headset 6 and various data. A storage unit 62, a sound collecting microphone 63, and a wireless communication unit 64 that communicates with the information display table 5 via wireless communication are provided.

  The CPU 51 of the information display table 5 determines whether or not the timing when the touch sound is collected by the microphone 63 of the headset 6 and the timing when the touch panel 56 reacts simultaneously with the coordinate detection of the touch point by the touch panel 56. Determined. When the headset 6 comes into contact with the screen of the display unit 57, a contact sound is collected by the microphone 63. The timing signal at the time of sound collection is input to the CPU 51 by the wireless communication unit 55. And CPU51 determines with the headset 6 contacting on the screen of the display part 57, when both reaction timing corresponds.

  When the data is displayed in the area including the coordinates (x1, y1) or the coordinates (x1, y1) associated with the unique information of the headset 6, the wireless communication unit 55 of the information display table 5 displays the display data. Related data is transmitted to the headset 6 via radio. In the case of this example, the display data displayed on the screen of the display unit 57 is an icon of audio data being reproduced, an icon of multimedia data, and the like, and the wireless communication unit 55 is related to these icons. Audio data is transferred to the headset 6. In the headset 6, the voice data transferred from the information display table 5 can be output as voice and the user can hear it.

  In addition, audio data is stored in the storage unit 62 of the headset 6 and data (in a region including coordinates (x1, y1) or coordinates (x1, y1) associated with the unique information of the headset 6 ( In this example, when the audio data icon) is not displayed, the wireless communication unit 55 of the information display table 5 receives the audio data from the headset 6 via the wireless communication, and the display unit 57 displays the wireless communication unit 55. The icon corresponding to the audio data received in is displayed in an area including coordinates (x1, y1) or coordinates (x1, y1).

  FIG. 4 is a diagram showing another example of the information display device according to the present invention. In this example, a case where an information display board 7 is applied as an information display device instead of the information display table 5 of FIG. 1 will be described. As shown in FIG. 4A, the information display board 7 is an electronic bulletin board for posting data such as communication items for an unspecified number of users or specific users. As shown in FIG. 4B, the information display board 7 includes a CPU 71, a coordinate detection unit 72, a storage unit 73, a display driver 74, a wireless communication unit 75, a touch panel 76, and a display unit 77, and an information display table. Although the basic configuration is the same as that of 5, the display screen is not divided into a plurality of areas, but is a single display screen.

  When the mobile terminal 1 comes into contact with the coordinates (x1, y1), the wireless communication unit 75 displays in the area including the coordinates (x1, y1) or the coordinates (x1, y1) associated with the unique information of the mobile terminal 1 The transmitted data is transmitted to the portable terminal 1 by radio. For example, when a plurality of image data 7 a to 7 d are displayed on the information display board 7, the image data 7 a corresponding to the contact coordinates (x1, y1) is selectively transmitted to the mobile terminal 1. When the map data is displayed on the information display board 7, the position information (longitude, latitude) corresponding to the contact coordinates (x1, y1) is selectively selected as the related data of the displayed map data. It transmits to the portable terminal 1.

  The mobile terminal 2 is associated with the region 7e including the coordinates (x2, y2) or the coordinates (x2, y2). Data is not displayed in the area 7e including the coordinates (x2, y2) or the coordinates (x2, y2) with which the mobile terminal 2 is associated. For this reason, the information display board 7 receives the data from the portable terminal 2 via radio, and displays the received data in an area including the coordinates (x2, y2) or the coordinates (x2, y2). When data is transferred from the portable terminal 2 to the information display board 7, for example, the data to be transferred can be flicked. The data transmission / reception starts after the association between the mobile terminals 1 and 2 and the contact coordinates (x1, y1) and (x2, y2) is completed. You may make it display the confirmation screen for confirming to a user whether it is OK on the portable terminals 1 and 2 or the information display board 7. FIG.

  FIG. 5 is a flowchart for explaining an example of a data link method between the information display table and the mobile terminal according to the present invention. In this example, a case where the dedicated area 5a including the coordinates (x1, y1) in FIG. 1 and the portable terminal 1 are associated with each other based on the apparatus configuration shown in FIG. 2 will be described. First, the information display table 5 is in a standby state when no approach of the mobile terminal 1 is detected (step S1). And the information display table 5 acquires the specific information (for example, MAC address) of the portable terminal 1 from the portable terminal 1 adjacent to the information display table 5 (step S2).

  Next, when the mobile terminal 1 physically touches the screen of the display unit 57 (Step S3), the information display table 5 detects the coordinates (x1, y1) of the contact point by the touch panel 56 (Step S4). Next, the information display table 5 determines whether or not the reaction timing of the acceleration sensor 13 of the mobile terminal 1 and the reaction timing of the touch panel 56 of the information display table 5 are simultaneous (step S5), and the acceleration sensor 13 and the touch panel. When it is determined that the reaction timings of 56 are not simultaneous (in the case of NO), it is determined that the touched device is not a mobile terminal, and the process returns to step S1 to shift to a standby state.

  In step S5, when it is determined that the reaction timing of the acceleration sensor 13 and the touch panel 56 is the same (in the case of YES), it is determined that the touched device is a mobile terminal, and the operation mode of the information display table 5 is the full screen mode. Or the dedicated area mode is determined (step S6). When it is determined that the operation mode is the dedicated area mode (in the figure, in the dedicated area mode), the dedicated area 5a including the coordinates (x1, y1) detected in step S4 is associated with the unique information of the mobile terminal 1 ( Step S7). The information display table 5 performs data communication with the mobile terminal 1 according to the dedicated area 5a associated with the unique information of the mobile terminal 1 (step S8).

  Here, in step S <b> 8, the information display table 5 transmits display data or related data of the display data to the mobile terminal 1 when the data is displayed in the dedicated area 5 a. Further, the information display table 5 can receive data from the portable terminal 1 and display the received data in the dedicated area 5a when data is not displayed in the dedicated area 5a.

  Further, when it is determined in step S6 that the operation mode is the full screen mode (in the case of the full screen mode in the figure), it is determined whether the contact location of the mobile terminal 1 is the application region or the background region. (Step S9). When it is determined that the contact location is the background area (in the case of the background area in the figure), the background area including the coordinates (x1, y1) detected in step S4 is associated with the unique information of the mobile terminal 1 (step S10). . The information display table 5 performs data communication with the mobile terminal 1 in accordance with the background area associated with the unique information of the mobile terminal 1 (step S11).

  When it is determined in step S9 that the contact location of the mobile terminal 1 is the application area (in the figure, the application area), the application area including the coordinates (x1, y1) detected in step S4 and the mobile terminal 1 Is associated with the unique information (step S12). Then, the information display table 5 performs data communication with the mobile terminal 1 in accordance with the application area associated with the unique information of the mobile terminal 1 (step S13).

  As described above, when the number of attendees changes during a meeting or the like using a plurality of persons using the information display table 5, the dedicated area is also reset following this. In the case of this example, the dedicated area including the coordinates (x1, y1) associated with the unique information of the mobile terminal 1 is reset. When the dedicated area changes due to the resetting, the CPU 51 associates the unique information of the mobile terminal 1 with the changed dedicated area. Thus, even when the dedicated area including the coordinates associated with the portable terminal 1 changes, the association with the portable terminal 1 can be continued following the change in the dedicated area.

  In addition, the storage unit 53 of the information display table 5 stores association information in which unique information of the mobile terminal 1 is associated with an area including coordinates (x1, y1). Thereby, even after the mobile terminal 1 is separated from the area including the coordinates (x1, y1), the association between the unique information of the mobile terminal 1 and the area including the coordinates (x1, y1) is maintained. . When the association information is stored in the storage unit 53, the CPU 51 includes an area including coordinates (x1, y1) associated with the unique information of the portable terminal 1 and other portable terminals other than the portable terminal 1. The association with is prohibited.

  When a predetermined operation on the information display table 5 is detected, the CPU 51 deletes the association information from the storage unit 53 and associates the unique information of the mobile terminal 1 with the area including the coordinates (x1, y1). Is released. Specifically, as the predetermined operation, for example, an operation such as turning off the power of the information display table 5 or bringing the mobile terminal 1 into contact with a predetermined area provided on the screen of the information display table 5 is performed. By doing so, the association between the area including the coordinates (x1, y1) and the mobile terminal 1 is released.

  FIG. 6 is a flowchart for explaining an example of a data linkage method between the information display board and the portable terminal according to the present invention. In this example, a case will be described in which the coordinates (x1, y1) or the coordinates (x2, y2) in FIG. 4A are associated with the mobile terminal 1 based on the apparatus configuration in FIG. First, the information display board 7 is in a standby state when the approach of the mobile terminal 1 is not detected (step S21). And the information display board 7 acquires the specific information (for example, MAC address) of the portable terminal 1 from the portable terminal 1 adjacent to the information display board 7 (step S22).

  Next, when the mobile terminal 1 physically contacts the screen of the display unit 77 (step S23), the information display board 7 detects the coordinates of the contact point with the touch panel 76 (step S24). Next, the information display board 7 determines whether or not the reaction timing of the acceleration sensor 13 of the mobile terminal 1 and the reaction timing of the touch panel 76 of the information display board 7 are simultaneous (step S25), and the acceleration sensor 13 and the touch panel. If it is determined that the reaction timing of 76 is not simultaneous (in the case of NO), the process returns to step S21 and shifts to a standby state.

  In step S25, when it is determined that the reaction timing of the acceleration sensor 13 and the touch panel 76 is the same (in the case of YES), whether or not data such as communication items or multimedia contents is displayed at the coordinates touched by the mobile terminal 1. Is determined (step S26). Here, when it is determined that data such as a contact item or multimedia content is displayed at the coordinates touched by the mobile terminal 1 (in the case of YES), the contact coordinates (here, coordinates (x1, x1)) where the data is displayed. y1)) is associated with the unique information of the portable terminal 1 (step S27). Then, the information display board 7 performs data communication (data transmission) with the mobile terminal 1 according to the contact coordinates (x1, y1) associated with the unique information of the mobile terminal 1 (step S28).

  In the above, in step S27, when the mobile terminal 1 contacts the coordinates (x1, y1), the mobile terminal 1 is associated with the coordinates (x1, y1). In step S28, the information display board 7 transmits the data displayed at the coordinates (x1, y1) associated with the unique information of the mobile terminal 1 to the mobile terminal 1 by radio. In the case of the example of FIG. 4 described above, the image data 7a corresponding to the contact coordinates (x1, y1) among the plurality of image data 7a to 7d displayed on the information display board 7 is selectively transmitted to the portable terminal 1. The

  If it is determined in step S26 that data such as contact items or multimedia contents is not displayed at the coordinates touched by the mobile terminal 1 (in the case of NO), the contact coordinates (in this case, the coordinates are not displayed). (X2, y2)) is associated with the unique information of the portable terminal 1 (step S29). Then, the information display board 7 performs data communication (data reception) with the mobile terminal 1 according to the contact coordinates (x2, y2) associated with the unique information of the mobile terminal 1 (step S30).

  In the above, in step S29, when the portable terminal 1 contacts the coordinates (x2, y2), the portable terminal 1 is associated with the coordinates (x2, y2). In step S30, as illustrated in FIG. 4A, data is not displayed in the area 7e including the coordinates (x2, y2). Data is received via radio, and the received data is displayed in an area 7e including coordinates (x2, y2).
