Embodiments for Carrying Out the Invention

[0009] (Knowledge on which the present disclosure is based) For example, in a shared space within a company or a shared office, there is a current situation where, despite the presence of multiple people from different companies or departments, there is little interaction among them. Interaction among multiple people from different departments may lead to new businesses or collaborations, or useful information for work may be obtained. Therefore, as a company, there is a desire to promote interaction among people who have had little interaction so far.

[0010] In the above prior art, when mobile terminals carried by users having desired profiles enter within the wireless communication range of each other, a mobile terminal capable of notifying a user that a person having the desired profile is nearby is disclosed.

[0011] However, in the prior art, since information regarding profiles is notified to the mobile terminals of each user, the user must always carry a mobile terminal equipped with a display unit, and often does not check the notifications of the mobile terminal, which is not suitable for promoting communication among people within a predetermined space.

[0012] In order to solve the above problems, the following technology is disclosed.

[0013] (1) An information processing method according to an aspect of the present disclosure is an information processing method executed by a computer, including receiving a signal from a sensor, determining whether a person is present within a predetermined space based on the received signal, and when it is determined that the person is present within the predetermined space, outputting a self-introduction image of the person to a display device installed within the predetermined space and viewable by a plurality of people.

[0030] According to this configuration, when a person attends an online meeting, the names of other attendees who attended the online meeting can be automatically registered on the table as the names of acquaintances. In addition, the speech during the online meeting may be analyzed, and not only the fact of simply attending but also the content of the meeting or conversation, such as the fact that they exchanged words or called each other's names, may be analyzed and registered.

[0031] (9) In the information processing method described in (5) above, further, receiving the input by each of the plurality of people of the information stored in the plurality of tables, and further creating the plurality of tables storing the information input by each of the plurality of people may be included.

[0032] According to this configuration, each of a plurality of people can create in advance a table for finding common terms among the plurality of people.

[0033] (10) In the information processing method described in (4) above, further, when it is determined that the plurality of people are in the predetermined space, it includes extracting different item contents of the plurality of people from a plurality of tables storing information of each of the plurality of people, and the output may include superimposing information regarding the different item contents on the self-introduction images of each of the plurality of people, and outputting the self-introduction images of each of the plurality of people on which the information regarding the different item contents is superimposed to the display device.

[0034] According to this configuration, self-introduction images of each of the plurality of people on which information regarding different item contents of the plurality of people is superimposed are displayed on the display device. Therefore, a plurality of people in a predetermined space can converse while making topics such as asking about different item contents of the plurality of people, so that the communication among the plurality of people in the predetermined space can be promoted.

[0035] (11) In the information processing method described in (10) above, the plurality of tables respectively store skill contents possessed by each of the plurality of people, the extraction includes extracting the different skill contents of the plurality of people from the plurality of tables, and the output may include superimposing information regarding the different skill contents on the self-introduction images of each of the plurality of people, and outputting the self-introduction images of each of the plurality of people on which the information regarding the different skill contents is superimposed to the display device.

[0036] According to this configuration, self-introduction images of each of the plurality of people on which information regarding different skill contents of the plurality of people is superimposed are displayed on the display device. Therefore, a plurality of people in a predetermined space can converse while making topics about different skill contents of the plurality of people, so that the communication among the plurality of people in the predetermined space can be promoted.

[0037] (12) In the information processing method according to any one of (4) to (11) above, when the plurality of persons is equal to or more than a predetermined number, the output may include outputting, to the display device, an incentive image for presenting an incentive given to the plurality of persons, together with the self-introduction images of the respective plurality of persons.

[0038] According to this configuration, when the plurality of persons is equal to or more than a predetermined number, an incentive image for presenting an incentive given to the plurality of persons is displayed on the display device together with the self-introduction images of the respective plurality of persons. Therefore, when a plurality of persons gather and the number thereof is equal to or more than a predetermined number, incentives are given to the plurality of persons, so that many persons who desire incentives can be gathered within a predetermined space. Note that conditions such as the number of persons not registered as acquaintances within a predetermined space being equal to or more than a predetermined number may be restricted.

[0039] (13) In the information processing method according to any one of (4) to (12) above, further including receiving, from a microphone, a voice signal obtained by collecting ambient voices, and when it is determined that the plurality of persons are within the predetermined space and the sound pressure level of the received voice signal is lower than a threshold value, the output may include outputting, to the display device, the self-introduction images of the respective plurality of persons.

[0040] According to this configuration, when the plurality of persons within a predetermined space are not conversing, the self-introduction images of the respective plurality of persons are displayed on the display device, so that a topic can be provided to the plurality of persons and the communication among the plurality of persons within the predetermined space can be promoted. Also, when they are already conversing, there is an effect of not disturbing the communication that is already taking place.

[0041] (14) In the information processing method according to any one of (4) to (13) above, the self-introduction image includes a first self-introduction image that does not describe the weaknesses of the person himself / herself, and a second self-introduction image that describes the weaknesses of the person himself / herself. Further, when it is determined that a first person and a second person are in a predetermined space, measuring the contact time during which both the first person and the second person are in the predetermined space, and further calculating the cumulative contact time of the first person and the second person up to the present. The output may include, when the cumulative contact time is shorter than a threshold value, outputting the first self-introduction image of each of the first person and the second person to the display device, and when the cumulative contact time is equal to or greater than the threshold value, outputting the second self-introduction image of each of the first person and the second person to the display device.

[0042] According to this configuration, when the cumulative contact time of the first person and the second person is shorter than the threshold value, that is, when the first person and the second person are not close, the first self-introduction image that does not describe the weaknesses of the person himself / herself is displayed on the display device. Also, when the cumulative contact time of the first person and the second person is equal to or greater than the threshold value, that is, when the first person and the second person are close, the second self-introduction image that describes the weaknesses of the person himself / herself is displayed on the display device.

[0043] Therefore, since the mutual weaknesses of the first person and the second person are displayed on the display device, by disclosing the mutual weaknesses according to the degree of intimacy, the degree of intimacy between the first person and the second person can be further enhanced. Also, since there is no need to disclose unnecessary information to a person whose degree of intimacy is not very high, there is an effect that it becomes easier to prepare more self-introduction images.

[0044] In addition, the present disclosure can be realized not only as an information processing method for executing the characteristic processing as described above, but also as an information processing apparatus having a characteristic configuration corresponding to the characteristic processing executed by the information processing method, and the like. Further, it can also be realized as a computer program for causing a computer to execute the characteristic processing included in such an information processing method.

[0048] (18)A non-transitory computer-readable recording medium according to another aspect of the present disclosure records an information processing program. The information processing program receives a signal from a sensor, determines whether a person is present in a predetermined space based on the received signal, and causes a computer to function so as to output a self-introduction image of the person to a display device installed in the predetermined space and viewable by a plurality of people when it is determined that the person is present in the predetermined space.

[0049] Embodiments of the present disclosure will be described below with reference to the accompanying drawings. Note that the embodiments described below are all specific examples of the present disclosure. The numerical values, shapes, components, steps, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Among the components in the following embodiments, components not described in the independent claims indicating the highest-level concept are described as optional components. Also, in all embodiments, the respective contents can be combined.

[0050] (Embodiment 1) FIG. 1 is a diagram showing the configuration of an image display system according to Embodiment 1 of the present disclosure.

[0051] The image display system shown in FIG. 1 includes a beacon transmitter 11, an information processing device 201, a display device 3, and an input device 4.

[0052] The beacon transmitter 11 is composed of, for example, a transmitter that transmits a beacon signal compliant with the communication protocol of BLE (Bluetooth (registered trademark) Low Energy). The beacon transmitter 11 is carried by a person and wirelessly transmits a beacon signal including a beacon ID (identification information) for identifying the person. The beacon ID is, for example, a UUID (Universally Unique Identifier), a Major ID, or a Minor ID, which uniquely identifies the beacon transmitter 11 and the person carrying the beacon transmitter 11. The beacon transmitter 11 transmits the beacon signal at a certain period. The beacon transmitter 11 includes a memory for pre-storing the beacon ID for identifying the person, and transmits the beacon signal with the beacon ID included therein. Note that the beacon transmitter 11 is an example of a sensor, and the beacon signal is an example of a signal.

[0053] The information processing device 201 includes, for example, at least a computer system including a control program, a processing circuit such as a processor or a logic circuit that executes the control program, and a recording device such as an internal memory or an accessible external memory that stores the control program. Note that the information processing device 201 may be realized, for example, by hardware implementation by a processing circuit, or by execution of a software program held in a memory by a processing circuit, or distributed from an external server, or by a combination of these hardware implementation and software implementation.

[0054] The information processing device 201 and the display device 3 are provided within a predetermined space. Note that the information processing device 201 may be a server. In this case, the information processing device 201 is communicably connected to a receiver that receives the beacon signal and the display device 3 via a network.

[0055] The predetermined space is a place where a plurality of people can gather, such as an office in an office, an entrance of a building, or a rest room in a building. In particular, the predetermined space is preferably a place where a plurality of people from different departments within a company or a shared office gather, or a place where a plurality of people from the same department within a company gather.

[0056] The information processing apparatus 201 includes a beacon reception unit 21, a person determination unit 22, a display control unit 25, a self-introduction image storage unit 27, and a self-introduction image creation unit 32.

[0057] The beacon reception unit 21 includes an antenna compatible with the BLE standard. The beacon reception unit 21 receives the beacon signal transmitted by the beacon transmitter 11. Also, the beacon reception unit 21 measures the radio wave intensity (RSSI (Received Signal Strength Indicator)) of the beacon signal received by the beacon reception unit 21.

[0058] The person determination unit 22 determines whether there is a person in a predetermined space based on the beacon signal received by the beacon reception unit 21. The person determination unit 22 determines whether there is a person in a predetermined space based on the radio wave intensity of the beacon signal received by the beacon reception unit 21. As the beacon transmitter 11 approaches the beacon reception unit 21 (information processing apparatus 201), the radio wave intensity of the beacon signal output from the beacon transmitter 11 increases. The information processing apparatus 201 is provided near the display device 3 in a predetermined space.

[0059] When the measured radio wave intensity of the beacon signal is equal to or greater than the threshold value, the person determination unit 22 determines that there is a person in the predetermined space. The threshold value is set to a radio wave intensity that can determine that the beacon transmitter 11 has entered the predetermined space. Also, when the measured radio wave intensity of the beacon signal is not equal to or greater than the threshold value, that is, when the measured radio wave intensity is lower than the threshold value, the person determination unit 22 determines that there is no person in the predetermined space.

[0060] The self-introduction image storage unit 27 stores self-introduction images of pre-created persons. The self-introduction image storage unit 27 stores the self-introduction image of a person in association with the beacon ID of the person. The self-introduction image includes information about the person such as the person's profile. Note that the self-introduction image storage unit 27 may store not only videos but also self-introduction voices, and the self-introduction may be made only with the self-introduction voice.

[0061] When the person determination unit 22 determines that there is a person in a predetermined space, the display control unit 25 outputs the self-introduction image of the person to a display device 3 installed in the predetermined space and viewable by a plurality of persons. When the person determination unit 22 determines that there is a person in a predetermined space, the display control unit 25 reads out from the self-introduction image storage unit 27 the self-introduction image corresponding to the beacon ID of the person in the predetermined space. The display control unit 25 outputs the self-introduction image read out from the self-introduction image storage unit 27 to the display device 3.

[0062] The display device 3 is, for example, a liquid crystal display device or a projector that projects an image onto a screen, is installed in a predetermined space, and is a display device viewable by a plurality of persons. The display device 3 displays the self-introduction image output by the display control unit 25.

[0063] The input device 4 is, for example, a keyboard, a mouse, or a touch panel, and accepts input of various information by a person. The input device 4 accepts input by a person of information about the person described in the self-introduction image.

[0064] The self-introduction image creation unit 32 creates a self-introduction image of a person. The self-introduction image creation unit 32 creates a self-introduction image in which the information about the person input by the input device 4 is described. The self-introduction image creation unit 32 stores the created self-introduction image in the self-introduction image storage unit 27 in association with the beacon ID of the creator.

[0065] FIG. 2 is a diagram showing an example of a self-introduction image in the first embodiment.

[0066] The self-introduction image 301 shown in FIG. 2 includes an image 311 showing a person, the name 312 of the person, the title 313 of the person, the words 314 the person likes, and the profile information 315 of the person.

[0067] The image 311 may be an image of a person taken, an illustration of a person drawn, or an image other than the person such as an animal the person likes.

[0068] The profile information 315 includes a plurality of items, including information regarding the inner self of the person, items such as the current job, skills, past jobs, hobbies, favorite things, or place of origin. The profile information 315 includes information regarding the person himself / herself that he / she wants to convey to other people. The profile information 315 may be text, or an image such as a photo or illustration. The profile information 315 shown in FIG. 2 is an example, and the profile information 315 may include other information. Also, the profile information 315 may include information regarding a plurality of the same items.

[0069] Note that the terminal device may receive an input from the person of the information described in the self-introduction image and create a self-introduction image. The terminal device is, for example, a smartphone, a tablet computer, or a personal computer. The terminal device is communicably connected to the information processing device 201 via a network. The receiving unit of the information processing device 201 may receive the self-introduction image created by the terminal device and store the received self-introduction image in the self-introduction image storage unit 27.

[0070] Subsequently, the image display process by the information processing device 201 in Embodiment 1 of the present disclosure will be described.

[0071] FIG. 3 is a flowchart for explaining the image display process by the information processing device 201 in Embodiment 1 of the present disclosure.

[0072] First, in step S1, the beacon receiving unit 21 receives the beacon signal transmitted by the beacon transmitter 11.

[0073] Next, in step S2, the beacon receiver 21 measures the radio field intensity of the beacon signal received by the beacon receiver 21.

[0074] Next, in step S3, the person determination unit 22 determines whether there is a person in a predetermined space. At this time, the person determination unit 22 determines whether the radio field intensity of the measured beacon signal is equal to or greater than a threshold value. And when it is determined that the radio field intensity of the measured beacon signal is equal to or greater than the threshold value, the person determination unit 22 determines that there is a person in the predetermined space. On the other hand, when it is determined that the radio field intensity of the measured beacon signal is not equal to or greater than the threshold value, the person determination unit 22 determines that there is no person in the predetermined space. Note that since it may be detected even if only passing through the predetermined space, the person determination unit 22 may further determine a time width, for example, that the radio field intensity is always below the threshold value for 5 seconds.

[0075] Here, when it is determined that there is no person in the predetermined space (NO in step S3), the process returns to step S1.

[0076] On the other hand, when it is determined that there is a person in the predetermined space (YES in step S3), in step S4, the display control unit 25 outputs a self-introduction image of the person corresponding to the beacon ID included in the beacon signal whose radio field intensity is equal to or greater than the threshold value to the display device 3. Here, the display control unit 25 reads out the self-introduction image associated with the beacon ID included in the beacon signal whose radio field intensity is equal to or greater than the threshold value from the self-introduction image storage unit 27. The display control unit 25 outputs the read self-introduction image to the display device 3. The display device 3 displays the self-introduction image output by the display control unit 25. After the self-introduction image is output to the display device 3, the process returns to step S1.

[0077] FIG. 4 is a diagram showing an example of a display screen displayed on the display device 3 in the first embodiment.

[0078] First, when the radio wave intensity of the beacon signal is not equal to or higher than the threshold value, the display device 3 may display the cover image 300. That is, when there is no person within a predetermined range from the display device 3, the display control unit 25 may output the cover image 300 to the display device 3, and the display device 3 may display the cover image 300.

[0079] And when the radio wave intensity of the beacon signal is equal to or higher than the threshold value, the display device 3 displays the self-introduction image 301 associated with the beacon ID included in the beacon signal whose radio wave intensity is equal to or higher than the threshold value. That is, when a person enters within a predetermined range from the display device 3, the display control unit 25 outputs the self-introduction image 301 to the display device 3, and the display device 3 displays the self-introduction image 301. The display screen of the display device 3 is switched from the cover image 300 to the self-introduction image 301. Note that the display device 3 may display the self-introduction image 301 while a person is within a predetermined space. Further, the display device 3 may alternately display the cover image 300 and the self-introduction image 301 at predetermined time intervals.

[0080] In this way, when there are a plurality of persons within a predetermined space and a person who has registered a self-introduction image in advance is among the plurality of persons, the self-introduction image of that person is displayed on the display device 3. Therefore, a person within a predetermined space can talk with other persons within the predetermined space while talking about the content of the self-introduction image of the person himself / herself displayed on the display device 3, so that the communication among the persons within the predetermined space can be promoted. Note that in the first embodiment, even when only one person is detected, the self-introduction image of that person is displayed. However, since it is assumed that an external person who does not have a beacon, such as a business traveler, is also within the predetermined space, communication can be expected.

[0081] (Embodiment 2) In the first embodiment, when there is one person within a predetermined space, the self-introduction image of the one person is displayed. However, in the second embodiment, when there are a plurality of persons within a predetermined space, the self-introduction images of the plurality of persons are displayed.

[0082] FIG. 5 is a diagram showing the configuration of the image display system according to Embodiment 2.

[0083] The image display system shown in FIG. 5 includes a plurality of beacon transmitters 11, 12, 13, an information processing device 202, a display device 3, and an input device 4. In Embodiment 2, the same components as those in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted.

[0084] The plurality of beacon transmitters 11, 12, 13 each have the same configuration as the beacon transmitter 11 in Embodiment 1. The plurality of beacon transmitters 11, 12, 13 are each held by a different person and transmit different beacon IDs. Note that the number of the plurality of beacon transmitters is not limited to three.

[0085] The information processing device 202 includes a beacon reception unit 21, a person determination unit 22, a number determination unit 23, a display control unit 25, a self-introduction image storage unit 27, and a self-introduction image creation unit 32.

[0086] The beacon reception unit 21 receives a plurality of beacon signals transmitted by the plurality of beacon transmitters 11, 12, 13. The beacon reception unit 21 also measures the radio wave intensity of each of the plurality of beacon signals received by the beacon reception unit 21.

[0087] The person determination unit 22 determines whether there is a person in a predetermined space based on the plurality of beacon signals received by the beacon reception unit 21. The person determination unit 22 determines whether there is a person in a predetermined space based on the radio wave intensity of each of the plurality of beacon signals received by the beacon reception unit 21.

[0088] The person determination unit 22 determines whether the radio wave intensity of each of the plurality of measured beacon signals is equal to or greater than a threshold value. If the radio wave intensity of at least one beacon signal is equal to or greater than the threshold value, the person determination unit 22 determines that there is a person in the predetermined space. Also, when the radio wave intensity of all of the plurality of beacon signals is lower than the threshold value, the person determination unit 22 determines that there is no person in the predetermined space.

[0089] When the person determination unit 22 determines that there is a person in a predetermined space, the number determination unit 23 determines whether there are a plurality of persons in the predetermined space. If the number of beacon signals with a radio wave intensity equal to or higher than the threshold is two or more, the number determination unit 23 determines that there are a plurality of persons in the predetermined space. On the other hand, if the number of beacon signals with a radio wave intensity equal to or higher than the threshold is one or less, the number determination unit 23 determines that there are no plurality of persons in the predetermined space.

[0090] When the number determination unit 23 determines that there are a plurality of persons in a predetermined space, the display control unit 25 outputs the self-introduction images of each of the plurality of persons to the display device 3. When the number determination unit 23 determines that there are a plurality of persons in a predetermined space, the display control unit 25 reads out the self-introduction images of each of the plurality of persons from the self-introduction image storage unit 27. The display control unit 25 outputs the plurality of self-introduction images read from the self-introduction image storage unit 27 to the display device 3.

[0091] The display device 3 displays the plurality of self-introduction images output by the display control unit 25. The display device 3 alternately displays the plurality of self-introduction images at a predetermined time interval. For example, the display device 3 may switch and display the plurality of self-introduction images every 30 seconds.

[0092] Subsequently, the image display process by the information processing device 202 in Embodiment 2 of the present disclosure will be described.

[0093] FIG. 6 is a flowchart for explaining the image display process by the information processing device 202 in Embodiment 2 of the present disclosure.

[0094] First, in step S11, the beacon reception unit 21 receives a plurality of beacon signals transmitted by the beacon transmitter 11.

[0095] Next, in step S12, the beacon reception unit 21 measures the radio wave intensity of each of the plurality of beacon signals received by the beacon reception unit 21.

[0096] Next, in step S13, the person determination unit 22 determines whether there is a person in a predetermined space. At this time, the person determination unit 22 determines whether the radio wave intensity of each of the plurality of beacon signals is equal to or greater than a threshold value. Then, if the radio wave intensity of at least one beacon signal is equal to or greater than the threshold value, the person determination unit 22 determines that there is a person in the predetermined space. On the other hand, when the radio wave intensity of all of the plurality of beacon signals is lower than the threshold value, the person determination unit 22 determines that there is no person in the predetermined space.

[0097] Here, when it is determined that there is no person in the predetermined space (NO in step S13), the process returns to step S11.

[0098] On the other hand, when it is determined that there is a person in the predetermined space (YES in step S13), in step S14, the number-of-people determination unit 23 determines whether there are a plurality of people in the predetermined space. If the number of beacon signals whose radio wave intensity is equal to or greater than the threshold value is two or more, the number-of-people determination unit 23 determines that there are a plurality of people in the predetermined space. On the other hand, if the number of beacon signals whose radio wave intensity is equal to or greater than the threshold value is one or less, the number-of-people determination unit 23 determines that there are not a plurality of people in the predetermined space. That is, when the number of beacon signals whose radio wave intensity is equal to or greater than the threshold value is one, or when the number of beacon signals whose radio wave intensity is equal to or greater than the threshold value is zero, the number-of-people determination unit 23 determines that there are not a plurality of people in the predetermined space.

[0099] Here, when it is determined that there are not a plurality of people in the predetermined space (NO in step S14), the process returns to step S11. That is, when there is no person in the predetermined space, or when there is one person in the predetermined space, the self-introduction image is not displayed.

[0100] On the one hand, when it is determined that there are a plurality of people in a predetermined space (YES in step S14), in step S15, the display control unit 25 outputs to the display device 3 the self-introduction images of each of the plurality of people corresponding to each of the plurality of beacon IDs included in each of the plurality of beacon signals whose radio wave intensity is equal to or greater than the threshold value. Here, the display control unit 25 reads from the self-introduction image storage unit 27 the plurality of self-introduction images associated with each of the plurality of beacon IDs included in each of the plurality of beacon signals whose radio wave intensity is equal to or greater than the threshold value. The display control unit 25 outputs the read plurality of self-introduction images to the display device 3. The display device 3 alternately displays the plurality of self-introduction images output by the display control unit 25. After the plurality of self-introduction images are output to the display device 3, the process returns to step S11.

[0101] FIG. 7 is a diagram showing an example of a display screen displayed on the display device 3 in the second embodiment.

[0102] When the radio wave intensities of two beacon signals are equal to or greater than the threshold value, the display control unit 25 outputs to the display device 3 two self-introduction images 301 and 302 associated with each of the two beacon IDs included in each of the two beacon signals whose radio wave intensity is equal to or greater than the threshold value. The display device 3 alternately displays the two self-introduction images 301 and 302 output by the display control unit 25. That is, when two people enter within a predetermined range from the display device 3, the display control unit 25 outputs the self-introduction image 301 and the self-introduction image 302 to the display device 3, and the display device 3 alternately displays the self-introduction image 301 and the self-introduction image 302. Note that the display device 3 may alternately display the cover image 300, the self-introduction image 301, and the self-introduction image 302 at predetermined time intervals.

[0103] As described above, when the number of people in a predetermined space is one or less, the self-introduction image is not displayed on the display device 3, and when the number of people in the predetermined space is two or more, the self-introduction image is displayed on the display device 3. Therefore, two or more people in the predetermined space can converse with each other while discussing the content of the displayed self-introduction images, thus promoting communication among the multiple people in the predetermined space. When the number of people in the predetermined space is one or less, the display device 3 may display various information as, for example, a workplace bulletin board, or may be used as digital signage.

[0104] Also, since the self-introduction images of multiple people in a predetermined space are displayed in real time, the multiple people can easily match their respective faces and names.

[0105] In addition, since the self-introduction images of multiple people in a predetermined space are automatically displayed, communication among multiple people can be promoted without the need for an intermediary to introduce people who do not know each other.

[0106] Note that in the second embodiment, the display device 3 alternately displays multiple self-introduction images. However, the present disclosure is not particularly limited to this, and multiple self-introduction images may be reduced and arranged side by side within one screen, or only specific parts of the self-introduction images, such as only the face photos, may be arranged and displayed.

[0107] (Embodiment 3) In the second embodiment, when there are multiple people in a predetermined space, self-introduction images of the multiple people are displayed. However, in the third embodiment, when there are multiple people in a predetermined space, a common term of the multiple people is extracted, and self-introduction images of the multiple people with information related to the extracted common term superimposed thereon are displayed.

[0108] FIG. 8 is a diagram showing the configuration of the image display system according to the third embodiment.

[0109] The image display system shown in FIG. 8 includes a plurality of beacon transmitters 11, 12, 13, an information processing device 203, a display device 3, and an input device 4. In the third embodiment, the same components as those in the first and second embodiments are denoted by the same reference numerals, and the description thereof is omitted.

[0110] The information processing device 203 includes a beacon reception unit 21, a person determination unit 22, a number of people determination unit 23, a common item extraction unit 24, a display control unit 25, a table storage unit 26, a self-introduction image storage unit 27, a contact time measurement unit 28, a contact determination unit 29, a registration unit 30, a table creation unit 31, and a self-introduction image creation unit 32.

[0111] When the number of people determination unit 23 determines that there are a plurality of people in a predetermined space, the common item extraction unit 24 extracts common items of the plurality of people from a plurality of tables storing information of each of the plurality of people.

[0112] The table storage unit 26 stores a plurality of tables storing information of each of the plurality of people. The table storage unit 26 stores a table for each of the plurality of people.

[0113] FIG. 9 is a diagram showing an example of a table of a first person in the third embodiment, and FIG. 10 is a diagram showing an example of a table of a second person different from the first person in the third embodiment.

[0114] The table associates a plurality of item names with the content of each of the plurality of item names. The plurality of items include, for example, beacon ID, place of residence, family composition, place of origin, alma mater, job content, past jobs, hobbies, skills, things one is not good at, supervisor, and acquaintances. Note that the plurality of items shown in FIGS. 9 and 10 are examples, and the table may include other items.

[0115] In the item of beacon ID, the beacon ID transmitted from the beacon transmitter held by a person is associated. In the item of place of residence, the name of the place where the person lives is associated. In the item of family composition, the family composition of the person is associated. In the item of place of origin, the place of origin of the person is associated. In the item of university attended, the name of the university where the person graduated is associated. In the item of job content, the current job content of the person is associated. In the item of past jobs, the past job content of the person is associated. In the item of hobbies, the hobbies of the person are associated. In the item of skills, the skills possessed by the person are associated. In the item of things one is bad at, the things the person is bad at are associated. In the item of supervisor, the name of the person's supervisor is associated. In the item of acquaintances, the names of the person's acquaintances are associated.

[0116] For example, when it is determined that the first person and the second person are in a predetermined space, the common item extraction unit 24 refers to the table of the first person and the table of the second person, and extracts items common to the first person and the second person from the two tables. In the examples of FIGS. 9 and 10, there are common items in the university attended (XXX University), past jobs (bicycles), and the names of acquaintances (AAA).

[0117] The display control unit 25 superimposes information on the common items extracted by the common item extraction unit 24 on the self-introduction images of each of the plurality of persons, and outputs the self-introduction images of each of the plurality of persons with the information on the common items superimposed thereon to the display device 3.

[0118] The plurality of tables respectively store the names of the acquaintances of each of the plurality of persons. The common item extraction unit 24 extracts the names of the acquaintances common to the plurality of persons from the plurality of tables. The display control unit 25 superimposes the names of the acquaintances common to the plurality of persons on the self-introduction images of each of the plurality of persons, and outputs the self-introduction images of each of the plurality of persons with the names of the acquaintances superimposed thereon to the display device 3.

[0119] When it is determined that there are a plurality of people in a predetermined space, the contact time measurement unit 28 measures the contact time of each combination of two people among the plurality of people in the predetermined space.

[0120] The contact determination unit 29 calculates the cumulative contact time so far for each combination of two people among the plurality of people in the predetermined space. The contact determination unit 29 determines whether the cumulative contact time of each combination of two people among the calculated plurality of people is equal to or greater than a threshold value. Then, the contact determination unit 29 determines whether there is a combination among the combinations of two people among the plurality of people whose cumulative contact time is equal to or greater than the threshold value.

[0121] When it is determined that there is a combination among the combinations of two people among the plurality of people whose cumulative contact time is equal to or greater than the threshold value, the registration unit 30 registers the names of each other as acquaintance names in the respective tables of the two people whose cumulative contact time is equal to or greater than the threshold value. For example, when the cumulative contact time of the first person and the second person is equal to or greater than the threshold value, the registration unit 30 registers the name of the second person as an acquaintance name in the table of the first person, and registers the name of the first person as an acquaintance name in the table of the second person.

[0122] In this way, the acquaintance names in the table can be automatically registered by measuring the time when a plurality of people are together.

[0123] The input device 4 accepts input by each of the plurality of people of information stored in the plurality of tables.

[0124] The table creation unit 31 creates a plurality of tables storing information input by each of the plurality of people. The table creation unit 31 stores the created plurality of tables in the table storage unit 26. The input device 4 accepts input by the person of the content of each of the plurality of items in the table. The items stored in the table are determined in advance, and the person inputs the content corresponding to the predetermined items.

[0125] As described above, each item in the table used when extracting common terms may be pre-entered by a person.

[0126] Subsequently, the image display process by the information processing apparatus 203 in Embodiment 3 of the present disclosure will be described.

[0127] FIG. 11 is a flowchart for explaining the image display process by the information processing apparatus 203 in Embodiment 3 of the present disclosure.

[0128] The processes of steps S21 to S24 are the same as the processes of steps S11 to S14 shown in FIG. 6, and thus the description thereof will be omitted.

[0129] When it is determined that there are a plurality of persons in a predetermined space (YES in step S24), in step S25, the common term extraction unit 24 refers to the tables of each of the plurality of persons in the predetermined space and determines whether there are common terms among the plurality of persons in the predetermined space.

[0130] Here, when it is determined that there are no common terms among the plurality of persons in the predetermined space (NO in step S25), the process proceeds to step S28.

[0131] On the other hand, when it is determined that there are common terms among the plurality of persons (YES in step S25), in step S26, the common term extraction unit 24 extracts the common terms of the plurality of persons in the predetermined space from the tables of each of the plurality of persons in the predetermined space. For example, in FIGS. 9 and 10, when there is the name of the same person among the names associated with the acquaintance item, it is determined that there are common terms among the plurality of persons in the predetermined space, and the common name of the person associated with the acquaintance item is extracted.

[0132] In addition, when there are three people in a predetermined space, there is a common term for two of the people, and there is no common term between each of the two people and the remaining one person, the common term of the two people is extracted. Also, when there are three people in a predetermined space and there is a common term for all three people, the common term of the three people is extracted.

[0133] Next, in step S27, the display control unit 25 superimposes information regarding the common term extracted by the common term extraction unit 24 on the self-introduction images of each of the plurality of people. For example, when there is a common name among the names associated with the acquaintance items of the plurality of people, the display control unit 25 extracts the common acquaintance name from the table and superimposes the acquaintance name on the self-introduction images of each of the plurality of people.

[0134] In addition, when there are three people in a predetermined space, there is a common term for two of the people, and there is no common term between each of the two people and the remaining one person, the common term of the two people is superimposed on the self-introduction images of the two people. The common term of the two people is not superimposed on the self-introduction image of the remaining one person. Also, when there are three people in a predetermined space and there is a common term for all three people, the common term of the three people is superimposed on the self-introduction images of the three people.

[0135] Next, in step S28, the display control unit 25 outputs the self-introduction images of each of the plurality of people to the display device 3. At this time, when there is a common term for the plurality of people, the display control unit 25 outputs the self-introduction images of each of the plurality of people with the information regarding the common term superimposed thereon to the display device 3. On the other hand, when there is no common term for the plurality of people, the display control unit 25 outputs the self-introduction images of each of the plurality of people without the information regarding the common term superimposed thereon to the display device 3.

[0136] FIG. 12 is a flowchart for explaining the table registration process by the information processing apparatus 203 in Embodiment 3 of the present disclosure.

[0137] The processes of steps S31 to S34 are the same as the processes of steps S11 to S14 shown in FIG. 6, and thus the description thereof is omitted.

[0138] When it is determined that there are a plurality of people in a predetermined space (YES in step S34), in step S35, the contact time measurement unit 28 measures the contact time for each combination of two people among the plurality of people in the predetermined space. For example, when a first person, a second person, and a third person are in a predetermined space, the contact time measurement unit 28 measures the contact time between the first person and the second person, the contact time between the first person and the third person, and the contact time between the second person and the third person, respectively. Note that depending on the threshold value in step S23, a relatively large area may be detected, and even if people are in the same place, the distance between them may not be a distance at which they can talk to each other. Therefore, the number of people determination unit 23 may further determine whether the radio wave intensities of the plurality of people with respect to each other are such that they are in the vicinity of each other.

[0139] Next, in step S36, the person determination unit 22 determines whether any of the plurality of people who were in the predetermined space has moved outside the predetermined space. When the radio wave intensity of any one of the beacon signals corresponding to the plurality of people who were in the predetermined space becomes smaller than the threshold value, the person determination unit 22 determines that any of the plurality of people who were in the predetermined space has moved outside the predetermined space.

[0140] Here, when it is determined that none of the plurality of people who were in the predetermined space has moved outside the predetermined space (NO in step S36), the process returns to step S35.

[0141] On the other hand, when it is determined that any of the plurality of people who were in the predetermined space has moved outside the predetermined space (YES in step S36), in step S37, the contact determination unit 29 calculates the cumulative contact time up to the present for each combination of two people among the plurality of people in the predetermined space. The cumulative contact time between the plurality of people is stored in a memory (not shown) of the information processing apparatus 203. The contact determination unit 29 calculates the cumulative contact time up to the present for each combination of two people among the plurality of people measured this time by the contact time measurement unit 28 by adding it to the respective cumulative contact times stored in the memory.

[0142] Next, in step S38, the contact determination unit 29 determines whether there is a combination of two out of a plurality of persons in which the cumulative contact time is equal to or greater than a threshold value. At this time, the contact determination unit 29 determines whether the cumulative contact time of each combination of two out of the calculated plurality of persons is equal to or greater than the threshold value.

[0143] Here, when it is determined that there is no combination in which the cumulative contact time is equal to or greater than the threshold value (NO in step S38), the process returns to step S31.

[0144] On the other hand, when it is determined that there is a combination in which the cumulative contact time is equal to or greater than the threshold value (YES in step S38), in step S39, the registration unit 30 registers each other's names as the names of acquaintances in the mutual tables of the two-person combination in which the cumulative contact time is equal to or greater than the threshold value.

[0145] In addition, in the third embodiment, the names of acquaintances are automatically registered in the table, but the present disclosure is not particularly limited thereto. When the names of acquaintances are registered in advance by a person in the table, the information processing apparatus 203 may not include the contact time measurement unit 28, the contact determination unit 29, and the registration unit 30.

[0146] FIG. 13 is a diagram showing an example of a display screen displayed on the display device 3 in the third embodiment.

[0147] When there is a common item among two people in a predetermined space, the common item extraction unit 24 extracts the common items of the two people in the predetermined space from the tables of the two people in the predetermined space. Then, the display control unit 25 superimposes the information 321 regarding the common item on the self-introduction images 301 and 302 of the two people respectively. In FIG. 13, since there is a common person's name in the acquaintance item of the tables of the two people, the information 321 regarding the common item is an image showing the common acquaintance's name of the two people. The display control unit 25 outputs the two self-introduction images 301 and the self-introduction image 302 with the information 321 regarding the common item superimposed thereon to the display device 3. The display device 3 alternately displays the two self-introduction images 301 and the self-introduction image 302 output by the display control unit 25. At this time, the information 321 regarding the common item is superimposed on the self-introduction image 301 and the self-introduction image 302. For example, the information 321 regarding the common item is represented by characters and includes the common item and its content.

[0148] In the third embodiment, the self-introduction images of each of the plurality of people with the information regarding the common items of the plurality of people superimposed thereon are displayed on the display device 3. Therefore, the plurality of people in the predetermined space can have a conversation while talking about the common items of the plurality of people, so that the communication among the people in the predetermined space can be promoted.

[0149] Note that in the third embodiment, the following modification examples can be adopted.

[0150] (1) When there are a plurality of common terms among a plurality of people in a predetermined space, the display control unit 25 may superimpose at least one of the plurality of common terms on the self-introduction image. For example, the display control unit 25 may randomly select a predetermined number of common terms from among the plurality of common terms and superimpose the selected predetermined number of common terms on the self-introduction image. Also, priorities may be set for the plurality of items in the table. Then, the display control unit 25 may select the one common term with the highest priority among the plurality of common terms and superimpose the selected one common term on the self-introduction image. Further, the display control unit 25 may select a predetermined number of common terms in descending order of priority among the plurality of common terms and superimpose the selected predetermined number of common terms on the self-introduction image.

[0151] (2) In the third embodiment, it is determined whether the cumulative contact time between the first person and the second person is equal to or greater than the threshold value, but the present disclosure is not particularly limited thereto. The information processing apparatus 203 may include an intimacy calculation unit that calculates the intimacy between the first person and the second person based on the cumulative contact time between the first person and the second person, the contact timing between the first person and the second person, and the contact frequency between the first person and the second person. The intimacy is represented, for example, in five levels from level 1 to level 5. The contact timing represents the date of year, month, and day when the first person and the second person last met. The contact frequency represents the number of times the first person and the second person have met. Then, the registration unit 30 may determine whether the calculated intimacy is equal to or greater than the threshold value. When the calculated intimacy is equal to or greater than the threshold value, the registration unit 30 may register the name of the second person as the name of an acquaintance in the table of the first person and register the name of the first person as the name of an acquaintance in the table of the second person. The threshold value is, for example, level 3.

[0152] For example, when the cumulative contact time is equal to or greater than a threshold value, the contact timing is after a predetermined time, and the contact frequency is greater than a predetermined number of times, the first person and the second person have an intimate relationship, so the intimacy level becomes the highest level 5. Also, for example, when the cumulative contact time is equal to or greater than a threshold value, the contact timing is before a predetermined time, and the contact frequency is greater than a predetermined number of times, the first person and the second person used to meet frequently in the past but have not met recently, so the intimacy level becomes the lowest level 1. Also, for example, when the cumulative contact time is shorter than the threshold value, the contact timing is after a predetermined time, and the contact frequency is greater than a predetermined number of times, the first person and the second person have met frequently recently but the contact time is short, so the intimacy level becomes the lowest level 1. When there are a plurality of common acquaintances, the names of the common acquaintances with a high intimacy level may be preferentially displayed.

[0153] (3) The information processing apparatus 203 may further include an acquisition unit that acquires the names of a plurality of attendees of an online meeting from the history of past online meetings. The acquisition unit may acquire the history of past online meetings from the terminal devices possessed by each of the plurality of persons. Then, the information processing apparatus 203 may further include a registration unit that registers the names of other attendees among the plurality of attendees as the names of acquaintances in the table of one of the attendees among the plurality of attendees.

[0154] (4) The information processing apparatus 203 may further include an acquisition unit that acquires the title of an online meeting from the history of past online meetings, and a registration unit that, when the title of the past online meeting includes a keyword indicating the content of work stored in advance, registers the keyword indicating the content of work in the item of the content of work in the table.

[0155] (5) The information processing apparatus 203 may further include an acquisition unit that acquires voice data of a plurality of attendees during an online meeting from the history of past online meetings, a conversion unit that converts the acquired voice data into text data, and a registration unit that, when the text data includes a keyword indicating the content of work stored in advance, registers the keyword indicating the content of work in the item of the content of work in the table.

[0156] (6) The information processing apparatus 203 may further include an acquisition unit that acquires information posted by a person in the posting column or chat column of an online meeting from the history of past online meetings, and a registration unit that registers a keyword indicating a skill, which is prestored, in the skill item of a table when the acquired information includes the keyword indicating the skill.

[0157] (7) When it is determined that there are a plurality of persons in a predetermined space, the information processing apparatus 203 may further include an extraction unit that extracts different item contents of the plurality of persons from a plurality of tables storing information of the plurality of persons respectively. The display control unit 25 may superimpose information regarding different item contents on the self-introduction images of the plurality of persons respectively, and output the self-introduction images of the plurality of persons with the information regarding different item contents superimposed thereon to the display device 3.

[0158] More specifically, the plurality of tables store the skill contents respectively possessed by the plurality of persons. The extraction unit may extract different skill contents of the plurality of persons from the plurality of tables. Then, the display control unit 25 may superimpose information regarding different skill contents on the self-introduction images of the plurality of persons respectively, and output the self-introduction images of the plurality of persons with the information regarding different skill contents superimposed thereon to the display device 3.

[0159] For example, in FIGS. 9 and 10, when the contents associated with the skill items of two persons are different, it is determined that the skill contents of the two persons in a predetermined space are different from each other, and the respective contents associated with the skill items are extracted.

[0160] (8) When it is determined that there are a plurality of people in a predetermined space, the information processing apparatus 203 further includes a measurement unit that measures the number of contacts for each combination of two people among the plurality of people in the predetermined space, a calculation unit that calculates the cumulative number of contacts up to the present for each combination of two people among the plurality of people, and a determination unit that determines whether there is a combination in which the cumulative number of contacts is the first time among the combinations of two people among the plurality of people. When there is a combination in which the cumulative number of contacts is the first time among the combinations of two people among the plurality of people, the display control unit 25 may superimpose information indicating that the two people have met for the first time on the self-introduction images of the two people respectively, and output to the display device 3 the self-introduction images of the two people with the information indicating that the two people have met for the first time superimposed thereon.

[0161] (9) The plurality of tables may each store the department names within the company to which each of the plurality of people belongs. When it is determined that there are a plurality of people in a predetermined space, the information processing apparatus 203 may further include an extraction unit that extracts the department names to which each of the plurality of people in the predetermined space belongs from the plurality of tables. Then, when there are two people whose departments are the same, the display control unit 25 may calculate the cumulative contact time up to the present of the two people. When the cumulative contact time is shorter than the threshold value, the display control unit 25 may output to the display device 3 the self-introduction images of the two people respectively and an image showing the organizational chart of the company. The display device 3 may alternately display the self-introduction images of the two people output from the display control unit 25 and the organizational chart of the company.

[0162] (10) The plurality of tables may store the skill contents each of the plurality of persons has and the skill contents each of the plurality of persons is looking for, respectively. When it is determined that there are a plurality of persons in a predetermined space, the information processing apparatus 203 may further include an extraction unit that extracts, from the plurality of tables, the skill contents each of the plurality of persons has and the skill contents each of the plurality of persons is looking for. When the skill content that one of the plurality of persons in a predetermined space is looking for matches the skill content that another person has, the display control unit 25 may output, to the display device 3, the self-introduction image of the one person and the self-introduction image of the other person with the display mode of the skill content changed. In this case, the display control unit 25 may output, to the display device 3, the self-introduction image of the other person with the skill content item made larger than other items.

[0163] (11) The information processing apparatus 203 includes an acquisition unit that acquires the title of an online meeting and the names of a plurality of attendees of the online meeting from the history of past online meetings, a first determination unit that determines whether or not the first person and the second person are meeting for the first time when it is determined that the first person and the second person are in a predetermined space, and a second determination unit that determines whether or not the first person and the second person are included among the attendees of the same online meeting when it is determined that the first person and the second person are meeting for the first time. The first determination unit may determine that the first person and the second person are meeting for the first time when the cumulative contact time is 0 hours or when the current contact count is the first time. When it is determined that the first person and the second person are included among the attendees of the same online meeting, the display control unit 25 may output, to the display device 3, a presentation image that presents the title of the online meeting attended by the first person and the second person and the self-introduction images of the first person and the second person, respectively. The presentation image may include, for example, a sentence such as "The two persons attended the online meeting 'XXX'." Here, "XXX" is the title of the online meeting.

[0164] This makes it possible to create an environment in which two persons who have participated in the same online meeting but are actually meeting for the first time can easily have a conversation.

[0165] (12) The information processing apparatus 203 may further include an acquisition unit that acquires the personality diagnosis results of each of a plurality of persons previously diagnosed by a personality diagnosis test, and a determination unit that determines whether there is a combination of two persons among the plurality of persons whose personality diagnosis results are the same. When there is a combination of two persons among the plurality of persons whose personality diagnosis results are the same, the display control unit 25 may superimpose information indicating that the personality diagnosis results of the two persons are the same on the self-introduction images of each of the two persons, and output to the display device 3 the self-introduction images of each of the two persons on which the information indicating that the personality diagnosis results of the two persons are the same is superimposed.

[0166] (13) When the number of the plurality of persons is equal to or more than a predetermined number, the display control unit 25 may output to the display device an incentive image for presenting an incentive given to the plurality of persons, together with the self-introduction images of each of the plurality of persons. The incentive is, for example, a free ticket or a discount ticket for food and drink such as coffee. There is a providing device that provides food and drink in or near a predetermined space. When a free ticket or a discount ticket for food and drink is displayed on the display device 3, the plurality of persons in the predetermined space can obtain food and drink from the providing device for free or at a discounted price.

[0167] (14) The image display system may be provided in a predetermined space and further include a microphone that collects ambient sound. The information processing apparatus 203 may further include a receiving unit that receives an audio signal obtained by collecting ambient sound from the microphone. When it is determined that there are a plurality of persons in the predetermined space and the sound pressure level of the received audio signal is lower than a threshold value, the display control unit 25 may output the self-introduction images of each of the plurality of persons to the display device 3. Note that when it is determined that there are a plurality of persons in the predetermined space and the sound pressure level of the received audio signal is equal to or higher than the threshold value, the display control unit 25 may not output the self-introduction images of each of the plurality of persons to the display device 3.

[0168] As a result, even if there are a plurality of people in a predetermined space, if the predetermined space is quiet, the self-introduction images of each of the plurality of people can be displayed, and the conversation among the plurality of people can be promoted.

[0169] (15) When the number of the plurality of people is equal to or more than a predetermined number, the display control unit 25 may output, to the display device, characters for promoting the conversation among the plurality of people together with the self-introduction images of each of the plurality of people. The characters for promoting the conversation among the plurality of people are, for example, the characters "The main character today is Mr. / Ms. XXX." Here, "XXX" represents the name of one of the plurality of people in the predetermined space. Note that the display control unit 25 may superimpose the characters for promoting the conversation among the plurality of people on the self-introduction image of one of the plurality of people. In this case, the characters for promoting the conversation among the plurality of people are, for example, the characters "The main character today".

[0170] (16) When the number of the plurality of people is equal to or more than a predetermined number, the information processing apparatus 203 may output a predetermined sound for promoting the conversation among the plurality of people to the speaker. The speaker is provided in the predetermined space and may output a predetermined sound for promoting the conversation among the plurality of people. The predetermined sound is, for example, a fanfare.

[0171] (17) The self-introduction image may include a first self-introduction image that does not describe the weaknesses of the person himself / herself and a second self-introduction image that describes the weaknesses of the person himself / herself. The self-introduction image storage unit 27 may store the first self-introduction image and the second self-introduction image for each person. When it is determined that a first person and a second person are in the predetermined space, the contact time measurement unit 28 measures the contact time during which the first person and the second person are both in the predetermined space. The contact time measurement unit 28 calculates the cumulative contact time of the first person and the second person up to the present. Then, when the cumulative contact time is shorter than the threshold value, the display control unit 25 may output the first self-introduction images of the first person and the second person to the display device 3. Further, when the cumulative contact time is equal to or more than the threshold value, the display control unit 25 may output the second self-introduction images of the first person and the second person to the display device 3.

[0172] In this way, when the cumulative contact time between the first person and the second person is shorter than the threshold value, that is, when the first person and the second person are not close, a first self-introduction image that does not describe the weaknesses of the person himself / herself is displayed on the display device 3. Also, when the cumulative contact time between the first person and the second person is equal to or greater than the threshold value, that is, when the first person and the second person are close, a second self-introduction image that describes the weaknesses of the person himself / herself is displayed on the display device 3. Therefore, since the weaknesses of each other between the first person and the second person are displayed on the display device 3, by talking about each other's weaknesses as a topic, the degree of intimacy between the first person and the second person can be further enhanced.

[0173] (18) The self-introduction image may include a first self-introduction image that does not describe the weaknesses of the person himself / herself and a second self-introduction image that describes the weaknesses of the person himself / herself. The self-introduction image storage unit 27 may store the first self-introduction image and the second self-introduction image for each person. The information processing device 203 may further include an extraction unit that extracts the names of the supervisors of each of the plurality of persons from a plurality of tables. Then, when it is determined that the first person and the second person are in a predetermined space and the second person is the supervisor of the first person, the display control unit 25 may output the first self-introduction image of the first person to the display device 3. Also, when it is determined that the first person and the second person are in a predetermined space and the second person is not the supervisor of the first person, the display control unit 25 may output the second self-introduction image of the first person to the display device 3.

[0174] In this way, when the second person is the supervisor of the first person, the first self-introduction image that does not describe the weaknesses of the first person is displayed, and when the second person is not the supervisor of the first person, the second self-introduction image that describes the weaknesses of the first person is displayed. Therefore, since the weaknesses of the person himself / herself are disclosed to a person who is not the supervisor, the conversation with a person who is not the supervisor can be promoted by talking about his / her own weaknesses. Also, since the weaknesses of the person himself / herself are not disclosed to a person who is the supervisor, the supervisor can talk with the subordinate without being concerned about the subordinate's weaknesses.

[0175] The information processing apparatus 203 may further include a storage unit that stores, in association with each other, a predetermined attribute among a plurality of attributes of a person and items not to be displayed when a person with the predetermined attribute is present. The attributes are, for example, gender, age, religion, or race. Then, when it is determined that there are a plurality of persons in a predetermined space, the display control unit 25 acquires the attributes of each of the plurality of persons in the predetermined space. When the acquired plurality of attributes include the predetermined attribute stored in the storage unit, the display control unit 25 may output to the display device 3 a self-introduction image with the items associated with the predetermined attribute deleted. Further, a beacon transmitter for visitors may be lent to a person outside the company. When a person outside the company having the beacon transmitter for visitors enters a predetermined space, it may be switched to a self-introduction image in which confidential information is not displayed. Note that the threshold value of the radio wave intensity for detecting that a person outside the company has approached the information processing apparatus 203 may be set higher than the normal threshold value.

[0176] In this way, since there are items not included in the self-introduction image according to the attributes of other persons, it is possible to display a self-introduction image that takes into account other persons with different values or confidential information that should not be disclosed.

[0177] (20) If it is determined that a first person and a second person are in a predetermined space, the information processing apparatus 203 may further include an event generation unit that generates an event for causing the first person and the second person to execute according to the cumulative contact time of the first person and the second person. Then, the display control unit 25 may output to the display device 3 a presentation image that presents the event generated by the event generation unit and self-introduction images of the first person and the second person respectively. When the cumulative contact time of the first person and the second person is less than or equal to a threshold value, the event generation unit may generate a first event for promoting the communication between the first person and the second person. The first event is, for example, an event of drawing pictures and exchanging them with each other within a predetermined time. Also, when the cumulative contact time of the first person and the second person is longer than the threshold value, the event generation unit may generate a second event for enhancing the intimacy between the first person and the second person. The second event is, for example, an event of complimenting each other within a predetermined time.

[0178] In this way, an event according to the cumulative contact time of the first person and the second person is generated, and the presentation image presenting the generated event is presented together with the self-introduction images, so that the first person and the second person can be made to execute the event and the communication between the first person and the second person can be further promoted.

[0179] (21) When the first person and the second person in a predetermined space are meeting for the first time, the display control unit 25 may set the display time of the self-introduction images of the first person and the second person respectively to be longer than the display time of the self-introduction images of the first person and the second person when they are not meeting for the first time in the predetermined space. For example, if the first person and the second person in a predetermined space are meeting for the first time, the self-introduction images of the two persons may be switched and displayed every 30 seconds, and if the first person and the second person in a predetermined space are not meeting for the first time, the self-introduction images of the two persons may be switched and displayed every 15 seconds.

[0180] (22) The information processing apparatus 203 may further include a sound control unit that outputs a predetermined sound to the speaker when the first person and the second person in a predetermined space meet for the first time. The speaker may be provided in the predetermined space and output the predetermined sound output by the sound control unit. The predetermined sound is, for example, a bell sound. Also, the sound control unit may output a predetermined sound to the speaker when the departments to which the first person and the second person belong within the company are the same and the first person and the second person meet for the first time.

[0181] (23) The display control unit 25 may display the self-introduction images of the first person and the second person respectively when the first person and the second person in a predetermined space meet for the first time in a manner different from the self-introduction images of the first person and the second person respectively when the first person and the second person in the predetermined space do not meet for the first time. For example, the display control unit 25 may make the color of the outer frame of the self-introduction images of the first person and the second person respectively when the first person and the second person in a predetermined space meet for the first time red.

[0182] (24) The display control unit 25 may output to the display device 3 the self-introduction images of the first person and the second person respectively that include only the names when the first person and the second person in a predetermined space meet for the first time. The display control unit 25 may output to the display device 3 the self-introduction images of the first person and the second person respectively that include a plurality of items for introducing themselves when the first person and the second person in a predetermined space do not meet for the first time.

[0183] (25) If it is determined that there are a plurality of persons in a predetermined space, the display control unit 25 may cause the display device 3 to display the self-introduction images of each of the plurality of persons side by side. For example, the display control unit 25 may display two self-introduction images of two persons side by side on one screen, or may display four self-introduction images of four persons side by side on one screen. Further, the display control unit 25 may display two or more self-introduction images of two or more persons who are meeting for the first time among the plurality of persons side by side on one screen. Further, the display control unit 25 may separately display two or more self-introduction images of two or more persons who are meeting for the first time among the plurality of persons, and may display two or more self-introduction images of two or more persons who are not meeting for the first time among the plurality of persons side by side on one screen.

[0184] (26) If the first person and the second person in a predetermined space are meeting for the first time, the display control unit 25 may output to the display device 3 the self-introduction images of the first person and the second person with the characters of their names enlarged.

[0185] (27) If it is determined that there are a first person, a second person, and a third person in a predetermined space, the first person and the second person are meeting for the first time, the first person and the third person are not in a predetermined relationship, and the second person and the third person are not meeting for the first time, the display control unit 25 may first display the self-introduction images of the first person and the second person, and then display the self-introduction image of the third person.

[0186] (28)In the third embodiment, the image display system includes one display device 3, but the present disclosure is not particularly limited thereto, and the image display system may include a plurality of display devices 3. When it is determined that there are a plurality of people in a predetermined space, the display control unit 25 may output the self-introduction images of each of the plurality of people to each of the plurality of display devices 3. At this time, the plurality of display devices 3 may display the self-introduction images of different people simultaneously without displaying the self-introduction images of the same person simultaneously. Further, a speaker may read out all the contents of the self-introduction image in voice. Further, the image display system may include a speaker instead of the display device 3, and the speaker may output a self-introduction voice. Further, the self-introduction image may be not only a still image but also a moving image.

[0187] (Embodiment 4) The information processing apparatuses according to the first to third embodiments receive the beacon signal transmitted by the beacon transmitter 11 and determine whether there is a person in a predetermined space based on the radio wave intensity of the received beacon signal. However, the information processing apparatus according to the fourth embodiment receives the image signal transmitted by the camera and determines whether there is a person in a predetermined space by recognizing the face of the person included in the received image signal.

[0188] FIG. 14 is a diagram showing the configuration of the image display system according to the fourth embodiment.

[0189] The image display system shown in FIG. 14 includes a camera 1, an information processing apparatus 204, a display device 3, and an input device 4. In the fourth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

[0190] The camera 1 transmits an image signal obtained by photographing a predetermined space. The camera 1 is disposed at a predetermined position where it is possible to photograph a predetermined space. For example, the camera 1 may be disposed on the display device 3. Note that the camera 1 is an example of a sensor, and the image signal is an example of a signal.

[0191] The information processing apparatus 204 includes an image receiving unit 21A, a person determination unit 22A, a display control unit 25, a self-introduction image storage unit 27, and a self-introduction image creation unit 32.

[0192] The image receiving unit 21A receives the image signal transmitted by the camera 1.

[0193] The person determination unit 22A determines whether there is a person in a predetermined space by recognizing the face of the person included in the image signal received by the image receiving unit 21A. The information processing apparatus 204 includes a memory (not shown) that pre-stores, in association with each other, identification information for identifying each of a plurality of persons and face images of each of the plurality of persons. The person determination unit 22A collates the face image included in the image signal received by the image receiving unit 21A with the plurality of face images stored in the memory, and if there is a face image in the plurality of face images stored in the memory that matches the face image included in the image signal, determines that there is a person in the predetermined space.

[0194] Note that the person determination unit 22A may recognize the face of the person included in the image signal by using the face image included in the self-introduction image stored in the self-introduction image storage unit 27.

[0195] Also, the person determination unit 22A may determine whether there is a person in a predetermined space by recognizing a marker such as a name tag included in the image signal received by the image receiving unit 21A.

[0196] The self-introduction image storage unit 27 stores the self-introduction image of the person in association with the identification information of the person. The self-introduction image in the fourth embodiment is the same as the self-introduction image in the first embodiment. When the person determination unit 22A determines that there is a person in a predetermined space, the display control unit 25 reads out the self-introduction image corresponding to the identification information of the person in the predetermined space from the self-introduction image storage unit 27.

[0197] Subsequently, the image display process by the information processing apparatus 204 in the fourth embodiment of the present disclosure will be described.

[0198] FIG. 15 is a flowchart for explaining the image display process by the information processing apparatus 204 in Embodiment 4 of the present disclosure.

[0199] First, in step S41, the image receiving unit 21A receives the image signal transmitted by the camera 1.

[0200] Next, in step S42, the person determination unit 22A recognizes the face of a person from the image signal received by the image receiving unit 21A. The person determination unit 22A extracts the face portion in the image signal received by the image receiving unit 21A, and collates the extracted face portion with a plurality of face images stored in advance in the memory, thereby recognizing the face of the person.

[0201] Next, in step S43, the person determination unit 22A determines whether there is a person in a predetermined space. At this time, if there is a face image that matches the face portion extracted from the image signal among the plurality of face images stored in advance in the memory, the person determination unit 22A determines that there is a person in the predetermined space. On the other hand, if there is no face image that matches the face portion extracted from the image signal among the plurality of face images stored in advance in the memory, the person determination unit 22A determines that there is no person in the predetermined space.

[0202] Here, if it is determined that there is no person in the predetermined space (NO in step S43), the process returns to step S41.

[0203] On the other hand, when it is determined that there is a person in a predetermined space (YES in step S43), in step S44, the display control unit 25 outputs to the display device 3 a self-introduction image of the person corresponding to the identification information of the face image that matches the face portion extracted from the image signal. Here, the display control unit 25 reads from the self-introduction image storage unit 27 a self-introduction image associated with the identification information of the face image that matches the face portion extracted from the image signal. The display control unit 25 outputs the read self-introduction image to the display device 3. The display device 3 displays the self-introduction image output by the display control unit 25. After the self-introduction image is output to the display device 3, the process returns to step S41.

[0204] Note that the self-introduction image displayed on the display device 3 in the fourth embodiment is the same as the self-introduction image displayed on the display device 3 in the first embodiment.

[0205] In the fourth embodiment, the person does not need to carry a sensor such as a beacon transmitter, and just by moving the person into a predetermined space, the self-introduction image of the person can be displayed on the display device 3.

[0206] (Embodiment 5) In the fourth embodiment, when there is one person in a predetermined space, the self-introduction image of one person is displayed. However, in the fifth embodiment, when there are a plurality of persons in a predetermined space, the self-introduction images of the plurality of persons are displayed.

[0207] FIG. 16 is a diagram showing the configuration of an image display system according to the fifth embodiment.

[0208] The image display system shown in FIG. 16 includes a camera 1, an information processing device 205, a display device 3, and an input device 4. In the fifth embodiment, the same components as those in the second and fourth embodiments are denoted by the same reference numerals, and the description thereof is omitted.

[0209] The information processing apparatus 205 includes an image receiving unit 21A, a person determination unit 22A, a number-of-people determination unit 23A, a display control unit 25, a self-introduction image storage unit 27, and a self-introduction image creation unit 32.

[0210] When the person determination unit 22A determines that there is a person in a predetermined space, the number-of-people determination unit 23A determines whether there are a plurality of people in the predetermined space. When two or more people's faces are recognized from the received image signal, the number-of-people determination unit 23A determines that there are a plurality of people in the predetermined space. On the other hand, when the number of recognized people's faces from the received image signal is one or less, the number-of-people determination unit 23A determines that there are no plurality of people in the predetermined space.

[0211] Next, the image display process by the information processing apparatus 205 in Embodiment 5 of the present disclosure will be described.

[0212] FIG. 17 is a flowchart for explaining the image display process by the information processing apparatus 205 in Embodiment 5 of the present disclosure.

[0213] The processes of steps S51 to S53 are the same as the processes of steps S41 to S43 shown in FIG. 15, and thus the description thereof is omitted.

[0214] When it is determined that there is a person in a predetermined space (YES in step S53), in step S54, the number-of-people determination unit 23A determines whether there are a plurality of people in the predetermined space. When the number of recognized people's faces from the received image signal is two or more, the number-of-people determination unit 23A determines that there are a plurality of people in the predetermined space. On the other hand, when the number of recognized people's faces from the received image signal is one or less, the number-of-people determination unit 23 determines that there are no plurality of people in the predetermined space. That is, when the number of recognized people's faces from the received image signal is one, or when the number of recognized people's faces from the received image signal is zero, the number-of-people determination unit 23 determines that there are no plurality of people in the predetermined space.

[0215] Here, when it is determined that there are no multiple persons in a predetermined space (NO in step S54), the process returns to step S51. That is, when there is no person in the predetermined space or there is one person in the predetermined space, the self-introduction image is not displayed.

[0216] On the other hand, when it is determined that there are multiple persons in a predetermined space (YES in step S54), in step S55, the display control unit 25 outputs to the display device 3 the self-introduction images of each of the multiple persons corresponding to the multiple pieces of identification information of each of the multiple face images that match the multiple face portions extracted from the image signal. Here, the display control unit 25 reads from the self-introduction image storage unit 27 the multiple self-introduction images associated with the multiple pieces of identification information of each of the multiple face images that match each of the multiple face portions extracted from the image signal. The display control unit 25 outputs the read multiple self-introduction images to the display device 3. The display device 3 alternately displays the multiple self-introduction images output by the display control unit 25. After the self-introduction images are output to the display device 3, the process returns to step S51.

[0217] Note that the self-introduction images displayed on the display device 3 in the fifth embodiment are the same as the self-introduction images displayed on the display device 3 in the second embodiment.

[0218] (Sixth Embodiment) In the fifth embodiment, when there are multiple persons in a predetermined space, the self-introduction images of the multiple persons are displayed. However, in the sixth embodiment, when there are multiple persons in a predetermined space, the common terms of the multiple persons are extracted, and the self-introduction images of the multiple persons with the information related to the extracted common terms superimposed are displayed.

[0219] FIG. 18 is a diagram showing the configuration of an image display system according to the sixth embodiment.

[0220] The image display system shown in FIG. 18 includes a camera 1, an information processing device 206, a display device 3, and an input device 4. In Embodiment 6, the same components as those in Embodiments 3, 4, and 5 are denoted by the same reference numerals, and the description thereof is omitted.

[0221] The information processing device 206 includes an image reception unit 21A, a person determination unit 22A, a number determination unit 23A, a common term extraction unit 24, a display control unit 25, a table storage unit 26, a self-introduction image storage unit 27, a contact time measurement unit 28, a contact determination unit 29, a registration unit 30, a table creation unit 31, and a self-introduction image creation unit 32.

[0222] The plurality of tables stored in the table storage unit 26 are the same as the plurality of tables in Embodiment 3. However, in this Embodiment 6, since the beacon ID is not used, the table includes an item of identification information instead of the item of beacon ID. Identification information for identifying a person is associated with the item of identification information.

[0223] Subsequently, the image display process by the information processing device 206 in Embodiment 6 of the present disclosure will be described.

[0224] FIG. 19 is a flowchart for explaining the image display process by the information processing device 206 in Embodiment 6 of the present disclosure.

[0225] The processes of Steps S61 to S64 are the same as the processes of Steps S51 to S54 shown in FIG. 17, and thus the description thereof is omitted.

[0226] The processes of Steps S65 to S68 are the same as the processes of Steps S25 to S28 shown in FIG. 11, and thus the description thereof is omitted.

[0227] FIG. 20 is a flowchart for explaining the table registration process by the information processing device 206 in Embodiment 6 of the present disclosure.

[0228] The processes of steps S71 to S74 are the same as the processes of steps S51 to S54 shown in FIG. 17, so the description thereof will be omitted.

[0229] The processes of steps S75 to S79 are the same as the processes of steps S35 to S39 shown in FIG. 12, so the description thereof will be omitted.

[0230] In addition, in the sixth embodiment, the following modification examples can be adopted.

[0231] (29) In the above-described third embodiment, the beacon transmitters 11, 12, and 13 and the camera 1 of the sixth embodiment may be used in combination. That is, when a plurality of persons are recognized from the image signal captured by the camera 1, the contact time measurement unit 28 may measure the contact time of each combination of two persons among the plurality of persons in a predetermined space. Then, the person determination unit 22 may determine whether a person is in a predetermined space based on a plurality of beacon signals received from the beacon transmitters 11, 12, and 13.

[0232] (30) Data used for the determination of the common term may be acquired from the image signal captured by the camera 1. In the sixth embodiment, the plurality of tables may store information regarding the color of today's clothes or information regarding a favorite color. The information processing apparatus 206 may further include a recognition unit that recognizes the color of a person's clothes from the received image signal. When the face of a person is recognized by the person determination unit 22A, the recognition unit recognizes the color of the clothes worn by the person. Then, the registration unit 30 may register the recognized color of the clothes in the item of the color of today's clothes or the item of the favorite color in the person's table.

[0233] (31) In the sixth embodiment, the plurality of tables may store information regarding a favorite brand. The information processing apparatus 206 may further include a recognition unit that recognizes the brand name of a person's clothing from the received image signal. When the face of a person is recognized by the person determination unit 22A, the recognition unit recognizes the logo of the brand attached to the clothing worn by the person. Then, the registration unit 30 may specify the brand name from the logo of the brand recognized by the recognition unit and register the specified brand name in the favorite brand item of the person's table.

[0234] (32) In the sixth embodiment, the information processing apparatus 206 includes a position detection unit that detects the positions of a first person and a second person in a predetermined space based on the received image signal, a determination unit that determines whether the first person and the second person are meeting for the first time, and an illumination control unit that controls lighting equipment so that light is irradiated toward the positions of the first person and the second person detected by the position detection unit when it is determined that the first person and the second person are meeting for the first time. The lighting equipment may irradiate light toward the positions of the first person and the second person in the predetermined space based on the control from the illumination control unit.

[0235] Note that the position of a person can also be detected based on a beacon signal.
