Below, the case where communication by a well-known videophone is possible between the person-in-charge terminal 4 and the information output system 1 is demonstrated as an example.

(processing)
Next, processing executed by the information output system 1 configured as described above will be described. The processes executed by the information output system 1 are roughly classified into a first output content determination process, a second output content determination process, and a third output content determination process. Hereinafter, each of these processes will be described. Here, as a premise that each process is started, the display unit 21 of the terminal device 2 has one output selected by the arbitrary method from the plurality of output content specifying information 22a recorded in the data recording unit 22. It is assumed that the content specifying information 22a is displayed. The user approaches the information output device 3 while hanging the terminal device 2 on the neck or holding it with a hand in such an orientation that the display unit 21 can be imaged by the information output device 3, for example. Note that the user can select the output content specifying information 22 a that matches information desired to be recognized by the terminal device 2 via the operation unit 20 and display the output content specifying information 22 a on the display unit 21. For example, in the case of a user who is an “adult” and an “expert”, and wants to browse the information as an “adult” (not an expert), the identification information corresponding to the “adult” is encrypted and generated When the 2D code that is the output content specifying information 22a is selected, or when it is desired to browse the information as “expert”, the output content specified by encrypting the identification information corresponding to “expert” The 2D code which is the information 22a is selected and displayed on the display unit 21.

(Processing-First output content determination processing)
The first output content determination process is a process for determining the content of information to be output by the information output device 3 based on the distance between the user and the output unit 30. FIG. 6 is a flowchart showing the first output content determination process (in the following description of each process, step is abbreviated as “S”).

  The first output content determination process is automatically started after the power to the information output system 1 is turned on, for example. When the first output content determination process is activated, the output content determination unit 33a acquires summary information from the multiple information DB 34d and displays it on the output unit 30 (SA1).

  Next, the distance specifying unit 33c determines whether or not the two-dimensional code as the output content specifying information 22a held by the user has been recognized (SA2). For example, image data captured by the camera 31 is subjected to image analysis using a known image analysis technique, and when a two-dimensional code is included, it is determined that the two-dimensional code has been recognized.

  As a result, when it is not determined that the two-dimensional code is recognized (SA2, No), the distance specifying unit 33c repeats the determination of whether the two-dimensional code is recognized (SA2). On the other hand, when it is determined that the two-dimensional code is recognized (SA2, Yes), the distance specifying unit 33c specifies the position of the user (SA3). For example, the user holds the terminal device 2 from the neck, the position of the two-dimensional code displayed on the display unit 21 of the terminal device 2 can be equated with the position of the user, and the position of the camera 31 and the output unit 30 On the assumption that the position can be identified, the direction of the user viewed from the output unit 30 is specified based on the position of the two-dimensional code in the image data captured by the camera 31. Furthermore, the distance from the output unit 30 to the user is specified based on the size of the two-dimensional code in the image data.

  Next, the output content determination unit 33a determines whether the distance between the user specified by the distance specifying unit 33c in SA3 and the output unit 30 is less than the reference distance α (SA4). Here, the specific value of the reference distance α is arbitrary, and is set as a distance at which the user can easily read the characters of the detailed information displayed on the output unit 30, for example.

  As a result, when the distance between the user and the output unit 30 is less than α (SA4, Yes), the output content determination unit 33a determines the content of the information to be output as detailed information, and from the multiple information DB 34d. The acquired detailed information is displayed on the output unit 30 (SA5). Thereby, when the user can read the characters of the detailed information, a larger amount of information can be displayed on the output unit 30 and provided to the user. Thereafter, the process returns to SA2, and it is determined again whether or not the two-dimensional code is recognized.

  On the other hand, if the distance between the user and the output unit 30 is greater than or equal to α (SA4, No), the output content determination unit 33a determines the content of the information to be output as summary information, returns to SA1, and returns to the overview. Information is displayed on the output unit 30 (SA1). As a result, when the distance between the user and the output unit 30 is large, summary information using a large amount of characters and images compared to the detailed information is displayed on the output unit 30 to provide user-readable information. can do. Thereafter, similarly, the processing from SA1 to SA5 is repeatedly executed at a predetermined cycle.

(Processing-second output content determination processing)
The second output content determination process is a process for determining the content of information to be output by the information output device 3 based on the user's personal attribute. FIG. 7 is a flowchart showing the second output content determination process.

  This second output content determination process is automatically started after the power to the information output system 1 is turned on, for example. When the second output content determination process is activated, the output content determination unit 33a acquires information for adults from the multiple information DB 34d and displays it on the output unit 30 (SB1).

  Next, the output content determination unit 33a determines whether or not the two-dimensional code as the output content specifying information 22a held by the user has been recognized (SB2). As a result, when it is not determined that the two-dimensional code is recognized (SB2, No), the output content determination unit 33a repeats the determination of whether the two-dimensional code is recognized (SB2).

  On the other hand, when it is determined that the two-dimensional code is recognized (SB2, Yes), the decoding unit 33b decodes the recognized two-dimensional code into the identification information as the output content specifying information 22a, and the output content determination unit 33a The attribute specifying information corresponding to the identification information decoded by the decoding unit 33b is acquired from the personal attribute DB 34a (SB3). In the example of FIG. 3, when the identification information decoded by the decoding unit 33b is the 2D code ID “001”, “adult” is acquired as the corresponding attribute specifying information. In the case where the attribute specifying information is displayed as a two-dimensional code on the display unit 21 of the terminal device 2, the attribute specifying information can be acquired by the decoding unit 33b decoding the two-dimensional code. It is not necessary to acquire attribute specifying information from the personal attribute DB 34a.

  Returning to FIG. 7, the output content determination unit 33a determines whether or not the attribute specifying information acquired in SB3 is “child” (SB4). As a result, when the attribute specifying information is “child” (SB4, Yes), the output content determination unit 33a determines the content of information to be output as information for children, and the information for children acquired from the multiple information DB 34d. Is displayed on the output unit 30 (SB5).

  On the other hand, when the attribute specifying information is not “child” in SB4 (SB4, No), or after the process of SB5, the output content determination unit 33a ends the second output content determination process.

  FIG. 8 is a diagram conceptually showing the display of the output unit 30 in the second output content determination process. FIG. 8A is a diagram showing a case where information for children is displayed, and FIG. It is a figure which shows the case where the information for adults is displayed. As shown in FIG. 8A, when the user is a child, there are many illustrations and photographs, the size of the output characters is large, and information for children using many hiragana characters is displayed. Thereby, when a user is a child, the information of the aspect and quantity which are easy to understand for a child can be provided to the said user. On the other hand, if the user is not a child, as shown in FIG. 8 (b), detailed information using few kanji and illustrations can be provided to the user, and information that is of interest to adults can be provided. Can be provided.

(Processing-Third output content determination processing)
The third output content determination process is a process for determining the content of information to be output by the information output device 3 based on the user's residence time in the output range of the output unit 30. FIG. 9 is a flowchart showing the third output content determination process.

  This third output content determination process is automatically started after the power to the information output system 1 is turned on, for example. When the third output content determination process is activated, the output content determination unit 33a acquires, for example, detailed information from the multiple information DB 34d and displays it on the output unit 30 (SC1).

  Next, the output content determination unit 33a determines whether or not the two-dimensional code as the output content specifying information 22a held by the user has been recognized (SC2). As a result, when it is not determined that the two-dimensional code has been recognized (SC2, No), the output content determination unit 33a repeats the determination of whether or not the two-dimensional code has been recognized (SC2).

  On the other hand, when it is determined that the two-dimensional code is recognized (SC2, Yes), the decoding unit 33b decodes the recognized two-dimensional code into the identification information as the output content specifying information 22a. The dwell time specifying unit 33d acquires, from the recognition history DB 34c, time information within the reference time β + 1 minutes from the current time among the time information corresponding to the identification information decoded by the decoding unit 33b (SC3). Here, although the specific value of the reference time β is arbitrary, for example, when the user is interested in the information output to the output unit 30, it is set as the minimum time for staying in the output range of the output unit 30. be able to. In the example of FIG. 5, when the identification information decoded by the decoding unit 33b is 2D code ID “002”, the reference time β is 5 minutes, and the current time is 13:10 on April 1, 2009, the 2D code The time information after “April 1, 2009 13:04” corresponding to the ID “002” is acquired.

  Returning to FIG. 9, the dwell time specifying unit 33d determines whether or not the difference between the latest time information and the current time in the time information acquired in SC3 is equal to or greater than the reference time γ (SC4). Here, the specific value of the reference time γ is arbitrary, for example, a time interval for storing information in the recognition history DB 34c, and a time interval in which the amount of information stored in the recognition history DB 34c does not become excessive ( For example, it can be set as 1 second).

  As a result, when the difference between the latest time information and the current time in the time information acquired at SC3 is not equal to or greater than the reference time γ (when it is less than γ) (SC4, No), information is stored in the recognition history DB 34c. The output content determination unit 33a determines again whether or not the two-dimensional code has been recognized (SC2).

  On the other hand, if the difference between the latest time information in the time information acquired at SC3 and the current time is greater than or equal to the reference time γ (SC4, Yes), the residence time specifying unit 33d determines that the identification information decoded at SC3 and the current time Is stored in the recognition history DB 34c in association with each other (SC5).

  Subsequently, the dwell time specifying unit 33d determines whether or not the user's dwell time in the output range of the output unit 30, that is, the difference between the first time information and the current time in the time information acquired in SC3 is greater than the reference time β. Is determined (SC6). In the example of FIG. 5, since the acquired first time information is “April 1, 2009 13:04” and the current time is April 1, 2009 13:10, the difference is 6 minutes. It is determined that it is longer than 5 minutes of the reference time β.

  Returning to FIG. 9, when it is determined that the difference between the first time information in the time information acquired at SC3 and the current time is not greater than the reference time β as a result of the determination at SC6 (when it is determined that β is less than or equal to) ( SC6, No), it is unknown whether the user is interested in the display content of the output unit 30, and the output content determination unit 33a determines again whether the two-dimensional code has been recognized (SC2).

  On the other hand, when it is determined that the difference between the first time information and the current time in the time information acquired at SC3 is larger than the reference time β (SC6, Yes), the output content determination unit 33a is decoded by the decoding unit 33b at SC3. The attribute specifying information corresponding to the identified identification information is acquired from the personal attribute DB 34a (SC7).

  Subsequently, the output content determination unit 33a acquires communication destination specifying information corresponding to the attribute specifying information acquired in SC7 (SC8), and communicates with the person-in-charge terminal 4 specified by the acquired communication destination specifying information. The unit 32 makes a call (SC9). 3 and 4, when the identification information decoded by the decoding unit 33b in SC3 is the 2D code ID “003”, “expert” is acquired as the corresponding attribute specifying information. Therefore, “03-0000-0002”, which is the contact number of the person in charge of “in-house expert”, is acquired as communication destination identification information corresponding to this. In this case, the communication unit 32 calls the telephone terminal as the person-in-charge terminal 4 specified by the person-in-charge contact number through the telephone network.

  Returning to FIG. 9, the output content determination unit 33a determines whether or not there is a response from the person-in-charge terminal 4 that has called in SC9 (SC10). As a result, when there is no response (No in SC10), the output content determination unit 33a determines whether or not a call has been made for a predetermined time (for example, 10 seconds) (SC11). If the call has not been made for 10 seconds or more (SC11, No), it is determined again whether there is a response from the person-in-charge terminal 4 (SC10). If the call has been made for 10 seconds or more (SC11, Yes). ) Since the person in charge is absent, the process returns to SC2 to determine whether or not the two-dimensional code is recognized.

  On the other hand, when there is a response from the person-in-charge terminal 4 (SC10, Yes), the output content determination unit 33a superimposes the videophone screen transmitted from the person-in-charge terminal 4 to the communication unit 32 on a part of the output unit 30. The communication unit 32 is caused to perform videophone communication with the person-in-charge terminal 4 (SC12). Thereafter, the output content determination unit 33a ends the third output content determination process.

  FIG. 10 is a diagram conceptually showing the display of the output unit 30 in the third output content determination process. As shown in FIG. 10, a user who is interested in the information displayed on the output unit 30 can obtain an opportunity to directly contact a person in charge corresponding to the personal attribute of the user.

(effect)
As described above, according to the embodiment, the output content specifying information 22a that is information held by the user and is to be output in the information output system 1 is photographed by the camera 31, and the photographing is performed. Based on the output content specifying information 22a, the content of the information to be output is determined. Thereby, the information of the appropriate content corresponding to each user can be output.

  In addition, since a two-dimensional code that can be captured by the camera 31 is used as the output content specifying information 22a, the display of the output content specifying information 22a by the terminal device 2 and the reading by the camera 31 are facilitated.

  Further, the user's attribute is specified based on the attribute specifying information specified by the output content specifying information 22a photographed by the camera 31, and the content of the information to be output is determined based on the specified attribute. You can output information that you are interested in or understand.

  Moreover, since the content of the information to be output is determined based on the distance between the user and the output unit 30, readable information can be provided according to the position of the user.

  Moreover, since the content of the information to be output is determined based on the user's residence time in the output range of the output unit 30, the content information corresponding to the user's interest in the information output to the output unit 30 is output. Can do.

  In addition, since the type of information to be output is specified from the plurality of types of information stored in the multiple information DB 34d, the information can be output in an aspect or output amount corresponding to the user.

  Further, in the conventional system, when the user is interested in the content of the information output by the output unit, the user has to ask the exhibitor how to contact the person in charge and contact the person in charge. . Therefore, there is a possibility that the user loses the opportunity to contact the person in charge due to the complexity of making contact. In this case, the exhibitor or the person in charge may lose a great opportunity to hear opinions directly from the user. On the other hand, according to the present embodiment, communication is performed using the communication destination specifying information, so that it is possible to give the user an opportunity to directly contact the person in charge corresponding to the user. it can.

[III] Modifications to Embodiments Although the embodiment has been described above, the specific configuration and means of the present invention are arbitrary within the scope of the technical idea of each invention described in the claims. Modifications and improvements can be made. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment of the invention and the details of the configuration, and only a part of the problems described above. May be solved, or only some of the effects described above may be achieved. Furthermore, according to the present invention, problems not described above may be solved or effects not described above may be achieved.

(About distribution and integration)
Further, each of the electrical components described above is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured. For example, a plurality of terminal devices 2 may be connected to the information output device 3 via the network 5 so that they can communicate with each other.

(Determination of output contents)
In the above-described embodiment, the content information determined by the output content determination unit 33a is output as it is from the output unit 30, but the user determines whether or not to output the determined content information from the output unit 30. You may ask for consent. In this case, a display requesting consent from the user may be output to the output unit 30, or may be output to the display unit 21 of the terminal device 2 using a known wireless technology such as a wireless LAN. Further, an input operation as to whether or not the user agrees may be performed via the operation unit 20 of the terminal device 2. Similarly, when calling the person-in-charge terminal 4 in the third output content determination process, the user may be asked for consent as to whether or not the call is to be made.

(About the relationship between each process)
The processes of the first output content determination process, the second output content determination process, and the third output content determination process described in the above embodiment may be executed in any combination. For example, the person in charge may be called only when the distance between the user and the output unit 30 is short by combining the first output content determination process and the third output content determination process.

(About terminal devices)
In the above-described embodiment, the two-dimensional code is displayed on the display unit 21 of the terminal device 2. However, even if the user holds a card on which the two-dimensional code is printed and the camera 31 captures the two-dimensional code. Good.

(Configuration-Terminal device-Operation unit)
The operation unit 20 is an operation unit for operating the terminal device 2, and a known operation unit such as a keyboard or a touch panel can be used. In particular, it is possible to select arbitrary information from a plurality of output content specifying information 22 a stored in the data recording unit 22 and accept an operation input for displaying on the display unit 21.

(Recognition of two-dimensional code)
In the above-described embodiment, the case where one user exists within the output range of the output unit 30 has been described as an example. However, the information output system 1 can be applied even when there are a plurality of users. . For example, if it is determined that a plurality of two-dimensional codes are included as a result of analyzing image data captured by the camera 31, the output content of information is determined based on the first recognized two-dimensional code. May be. Alternatively, attribute identification information corresponding to all recognized two-dimensional codes is acquired, and based on the acquired attribute identification information, content that matches the user with the lowest understanding level (for example, a child) is determined as output content. Also good. Alternatively, the content that matches the user corresponding to the attribute specifying information with the largest number of people among the attribute specifying information corresponding to all recognized two-dimensional codes may be determined as the output content.

(About the third output content determination process)
In the above-described embodiment, when it is determined that the difference between the first time information in the time information acquired from the recognition history DB 34c and the current time is greater than the reference time β, the user stays in the output range of the output unit 30. The person-in-charge terminal 4 is called, but the presence or absence of the user may be determined based on other criteria. For example, when the two-dimensional code held by the user is continuously recognized for a certain time or more, it may be determined that the user is staying. Or you may determine based on the frequency | count of acquisition of the two-dimensional code which a user hold | maintains.

(About output content specific information)
In the above-described embodiment, it has been described that the terminal device 2 displays the output content specifying information 22a recorded in the data recording unit 22 on the display unit 21, but the output content specifying from the center device that supervises the information output system 1 is performed. The information 22a may be transmitted to the terminal device 2 and displayed on the display unit 21.

  For example, the center device is communicably connected to at least the terminal device 2 via a network such as a telephone network or the Internet, and includes a communication unit and an output content specifying information storage unit. As this center device, for example, a known information processing device such as a server or a PC can be used.

  The communication means is a communication control means for the center apparatus to perform communication via the network, and is configured as a network board, for example.

  The output content specifying information storage means stores terminal identification information capable of uniquely identifying the terminal device 2 and output content specifying information to be displayed on the terminal device 2 in association with each other. The timing and method of storing these pieces of information in the output content specifying information storage unit are arbitrary, and are input via, for example, a known input unit or network.

  In the center device configured as described above, the communication unit transmits the output content specifying information corresponding to the terminal identification information to the terminal device 2 specified based on the terminal identification information, and causes the display unit 21 to display the output content specifying information.

  For example, when the terminal device 2 is loaned to a visitor to the exhibition facility, the terminal identification information of the loaned terminal device 2 and the output content specifying information corresponding to the personal attribute of the visitor are mutually exchanged by the administrator. Assume that the information is stored in the output content specifying information storage means. In this case, the communication unit transmits the output content specifying information corresponding to the terminal identification information to the terminal device 2 specified based on the terminal identification information. The display unit 21 of the terminal device 2 displays the output content specifying information received from the center device. Then, the output content determination unit 33 a of the information output device 3 determines the content of information to be output to the output unit 30 based on the output content specifying information displayed on the terminal device 2. Thereby, the information of the content suitable for the user holding the terminal device 2 can be output from the output unit 30.

  According to such a system, it is possible to instruct and control the content to be viewed by the visitors to the exhibition facility on the center side, and it is easy to restrict viewing to the visitors.

  The information output system according to the present invention is useful for an information output system that can output information of contents corresponding to individual users.
