  The related information acquisition unit 232 collects the location information acquired by the user terminal 10 and stores it in the location information storage unit 222. For example, the related information acquisition unit 232 receives location information and user identification information (for example, terminal ID) from the user terminal 10 via the NW communication unit 21, and receives the received location information and user identification information as shown in FIG. As shown in FIG. That is, the related information acquisition unit 232 stores “terminal ID”, “location information”, “acquisition date / time”, and “manual input flag” in association with each other.

  The related information acquisition unit 232 acquires location information and user related information, and stores the acquired information in the related information storage unit 223. The related information acquisition unit 232, for example, from the storage location of the schedule indicated in the “schedule information” of the user terminal 10 or the related information storage unit 223, via the NW communication unit 21, the related information of the location information and the user's Acquire user related information such as schedule information. The related information acquisition unit 232 stores the acquired related information in the related information storage unit 223 as illustrated in FIGS. 4A and 4B.

  Based on the location information and user identification information stored in the location information storage unit 222, the situation estimation unit 233 is a user situation indicating a situation where the user is placed, and at least location information indicating a place where the user is present, and Estimate the user's situation including the user's state. For example, the situation estimation unit 233 acquires at least the location information stored in the related information acquisition unit 232 and related information related to any of the users, and based on the acquired related information, the location information, and the user identification information Estimate the user's situation.

  For example, when the location information and the user identification information are “AP1” of “location information” and “T001” of “terminal ID”, as shown in FIG. Based on the related information of the location information shown in (1), “Location” is “Conference Room A” and “Status” is “Conference”. Further, the situation estimation unit 233 searches the user information storage unit 221 to acquire “U001” of “user ID” corresponding to “T001” of “terminal ID”, and as related information corresponding to “U001” , Related information such as “Taro XX” of “Name” and “10:00 to 11:00 Meeting” of “Schedule Information” shown in FIG. Based on the acquired “location information” and “terminal ID” and related information, the situation estimation unit 233 estimates the situation of the user that “Taro XX is in a meeting in the conference room A”. To do. The situation estimation unit 233 stores the estimated user situation in the user situation storage unit 224 as shown in FIG. 5 described above.

For example, when the user is in a break room or a smoking room, the situation estimation unit 233 estimates the state of the user as “resting”. For example, when the user is in a free address area (room), The user's state is estimated to be “present”. In addition, the situation estimation unit 233 acquires a person who is with (close to) the user via the user terminal 10 or from schedule information, and the relationship (relationship) between the user and the place is obtained. The user state may be estimated.
The user's situation includes information such as when (time, etc.), where (location information such as location name), who and what (user status and behavior), The situation estimation unit 233 estimates one of these pieces of information.

In addition, when the information is insufficient to estimate the user's situation, the situation estimation unit 233 causes the notification processing unit 234 (to be described later) to execute an inquiry process or the like, and is insufficient. Insufficient information, which is information, is acquired, and a user's situation is estimated based on the acquired insufficient information.
In addition, when a plurality of user situations are estimated, the situation estimation unit 233 sends a notification for acquiring information that can determine the user situation from among the plurality of estimated user situations, as will be described later. 234, and based on the determinable information, the user status is determined from among a plurality of estimated user statuses.

  The notification processing unit 234 transmits the user situation estimated by the situation estimation unit 233 to the user terminal 10 corresponding to the designated user. The notification processing unit 234 transmits the user status to, for example, the boss of the estimation target user. Moreover, the notification process part 234 transmits a user's condition to the user terminal 10 corresponding to the designated user, when a predetermined notification condition is satisfied. Here, the predetermined notification condition is, for example, when a predetermined time is reached, when location information is acquired at the beginning of the day, when an inquiry about the user's situation from another user such as a boss, For example, when there is a notification request. When notifying the user status, the notification processing unit 234 transmits the notification to the user terminal 10 corresponding to the designated user via the NW communication unit 21 and the chat server 30 described later.

  In addition, when the situation estimation unit 233 estimates a plurality of user situations for the estimation target user, the notification processing unit 234 can determine the user situation from among the plurality of estimated user situations. Is transmitted to the user terminal 10 corresponding to the estimation target user. For example, the notification processing unit 234 transmits, via the chat server 30, to the estimation target user, a notification of inquiries and a notification for selecting one of a plurality of estimated user situations.

  In addition, the notification processing unit 234 obtains insufficient information that is insufficient for estimating the user situation when the situation estimation unit 233 lacks information for estimating the user situation. The notification is transmitted to the user terminal 10 corresponding to the estimation target user. For example, when the location name cannot be specified from the location information, the notification processing unit 234 transmits a notification for inquiring about the current location name to the estimation target user. Note that the notification processing unit 234 stores information obtained by the inquiry such as insufficient information in the related information storage unit 223 as related information.

  The Web processing unit 235 executes Web processing for notifying and providing various types of information and acquiring various types of input information. The web processing unit 235 performs, for example, processing such as adding a user's position to a seating chart in a room area and displaying the same on the user terminal 10, setting processing of various information of the information notification system 1, registration processing, and the like. Execute.

  The chat server 30 is a server device that can be connected to the user terminal 10 via the network NW1, and performs information notification such as message notification and chat to the user. The chat server 30 includes, for example, an NW communication unit 31 and a chat processing unit 32.

The NW communication unit 31 connects to the network NW1 using wireless LAN communication, wired LAN communication, or the like, and performs various types of communication via the network NW1. For example, the NW communication unit 31 is connected to the user terminal 10 and the location information server 20 via the network NW1, and performs various communications with the user terminal 10 and the location information server 20.
The chat processing unit 32 executes chat processing such as transmission / reception of a message (notification) between the user terminals 10 or between the user terminal 10 and the location information server 20.

Next, the information notification system 1 according to the present embodiment will be described with reference to the drawings.
FIG. 6 is a flowchart illustrating an example of a user situation estimation process in the present embodiment.

  As shown in FIG. 6, in the information notification system 1, when estimating a user situation, the situation estimation unit 233 of the location information server 20 first acquires the location information of the target user (estimation target user) ( Step S101). The situation estimation unit 233 acquires location information corresponding to the target user from the location information storage unit 222.

  Next, the situation estimation unit 233 acquires related information (step S102). The situation estimation unit 233 acquires related information related to the target user and related information related to the location information from the related information storage unit 223.

  Next, the situation estimation unit 233 determines whether or not the situation of the target user can be estimated (step S103). The situation estimation unit 233 advances the process to step S105 when the situation of the target user can be estimated (step S103: YES). Moreover, the situation estimation part 233 advances a process to step S104, when the situation of an object user cannot be estimated (it is impossible) (step S103: NO).

  In step S104, the situation estimation unit 233 executes a process of acquiring insufficient information (step S104). The situation estimation unit 233, for example, causes the notification processing unit 234 to execute inquiry processing or the like for the user to acquire insufficient information. The notification processing unit 234 sends an inquiry notification to the user terminal 10 of the target user via the chat server 30, and acquires deficient information via the chat server 30.

  In step S105, the situation estimation unit 233 estimates the situation of the target user. The situation estimation unit 233 estimates the user situation such as the user location and the user status based on the above-described user identification information, location information, and related information, for example. Here, the situation estimation unit 233 estimates a plurality of situations when a plurality of situations of the target user can be estimated.

  Next, the situation estimation unit 233 determines whether or not the estimated situation of the target user is unique (step S106). The situation estimation unit 233 advances the process to step S108 when the estimated situation of the target user is unique (step S106: YES). Moreover, the situation estimation part 233 advances a process to step S107, when the situation of the estimated target user is not unique (it is plurality) (step S106: NO).

  In step S107, the situation estimation unit 233 executes processing for determining the situation of the target user. That is, the situation estimation unit 233 executes processing for acquiring information that can determine the user's situation. The situation estimation unit 233, for example, causes the notification processing unit 234 to transmit a notification for acquiring information that can determine the user's situation, and acquires information for determining the situation of the target user. The notification processing unit 234 sends an inquiry notification to the target user's user terminal 10 via the chat server 30 and acquires information to be confirmed via the chat server 30. Then, the situation estimation unit 233 decides the situation of the target user based on the information to be decided.

  In step S108, the situation estimation unit 233 stores the situation of the target user in the user situation storage unit 224. For example, as illustrated in FIG. 5 described above, the situation estimation unit 233 stores the situation of the target user in the user situation storage unit 224. After the process of step S108, the situation estimation unit 233 ends the estimation process.

Next, an example of the operation of the information notification system 1 according to the present embodiment will be described with reference to FIG.
FIG. 7 is a diagram illustrating an example of the operation of the information notification system 1 according to the present embodiment.

  As shown in FIG. 7, first, the user terminal 10-1 detects the location information, and periodically transmits the location information and the terminal ID to the location information server 20 (step S201). The terminal control unit 14 of the user terminal 10-1 uses the location information such as the UUID of the beacon detected by the location detection unit 15 as location information, and transmits the location information to the location information server 20 via the NW communication unit 11 together with the terminal ID.

  FIG. 8A is an example of a display screen of the user terminal 10-1 when location information is detected by a beacon. In this case, the user terminal 10-1 displays the display screen G1 on the display unit 13. Further, as shown in the display screen G1, the user terminal 10-1 may display the detected date and time and the place name when the location information is detected by the beacon.

Next, the location information server 20 accumulates the location information and the terminal ID (step S202). That is, the location information collection unit 231 of the location information server 20 receives the location information and the terminal ID via the NW communication unit 21, and stores the location information and the terminal ID in the location information storage unit 222 together with the date and time information, for example, as shown in FIG. Let In the process of step S202, the notification processing unit 234 of the location information server 20 indicates that the location information has been registered via the chat server 30 as shown in FIG. You may make it notify to the terminal 10-1. A display screen G2 illustrated in FIG. 8B illustrates a display example in which the location information is registered on the display unit 13 of the user terminal 10-1 of the user A.
Note that the processing in step S201 and step S202 is periodically executed for each user terminal 10.

[Second Embodiment]
Next, an information notification system 1a according to the second embodiment will be described with reference to the drawings.
In the present embodiment, a modification example in which a notification destination of notification information is selected based on a user situation (context information) such as a location and a user state will be described.

FIG. 12 is a block diagram illustrating an example of the information notification system 1a according to the second embodiment.
As shown in FIG. 12, the information notification system 1a includes a user terminal 10 (10-1, 10-2,...), A location information server 20a, and a chat server 30.
In this figure, the same components as those in FIG. 1 described above are denoted by the same reference numerals, and description thereof is omitted here.

The location information server 20a is a server device that can be connected to the user terminal 10 and the chat server 30 via the network NW1, and the basic functions are the same as those of the location information server 20 of the first embodiment. The location information server 20a selects a notification destination user of notification information such as a message based on the context information indicating the user's situation, and notifies the selected user of the notification information.
The location information server 20a includes an NW communication unit 21, a server storage unit 22a, and a server control unit 23a.

  The server storage unit 22a stores various information used by the location information server 20a. The server storage unit 22a includes, for example, a user information storage unit 221, a location information storage unit 222, a related information storage unit 223, a user situation storage unit 224, and a group storage unit 225. The basic function of the server storage unit 22a is the same as that of the server storage unit 22 according to the first embodiment, and the server storage unit 22a is different from the first embodiment in that it includes a group storage unit 225.

The group storage unit 225 stores group information related to a notification destination group. For example, as illustrated in FIG. 13, the group storage unit 225 stores “group name” and “target user” in association with each other.
FIG. 13 is a diagram illustrating an example of data in the group storage unit 225 in the present embodiment.
In this figure, “group name” is identification information for identifying a group, and is, for example, a part of context information. “Target user” indicates the user ID of the user classified into this group.

  In the example illustrated in FIG. 13, the “target user” whose “group name” corresponds to “conference room A” is “U001, U003,...”. In addition, the “target user” corresponding to the “group name” “going out” is “U002, U009,...”.

  Returning to the description of FIG. 12, the server control unit 23a is, for example, a processor including a CPU and the like, and comprehensively controls the location information server 20a. The server control unit 23 a includes a location information collection unit 231, a related information acquisition unit 232, a situation estimation unit 233, a notification processing unit 234, a Web processing unit 235, and a notification destination selection unit 236. The basic function of the server control unit 23a is the same as that of the server control unit 23 according to the first embodiment, and the server control unit 23a is different from the first embodiment in that the server control unit 23a includes a notification destination selection unit 236.

  The notification destination selection unit 236 selects a notification destination user of the notification information based on the context information indicating the user status. For example, the notification destination selection unit 236 selects a notification destination user based on the user situation (context information) estimated by the context estimation unit. For example, the notification destination selection unit 236 classifies the user into a group related to the context information based on the context information, selects the group based on the context information specified by the notification source user, and selects the selected group. The user classified into (1) is selected as a notification destination user.

  Specifically, the notification destination selection unit 236 classifies users into groups related to the specified context information, and associates “group name” with “target user” as shown in FIG. Stored in the unit 225. Further, the notification destination selection unit 236 selects “target user” corresponding to the group related to the specified context information as the notification destination user in the group storage unit 225.

  Note that when selecting a notification destination based on context information, for example, when a document or message is sent to all attendees during a meeting or seminar, a user who has the same status as the sender There are a case where notification is made and a case where notification is made to a user in a situation different from the transmission source, for example, when a message is notified to a user who is out. For example, when notifying a user in the same situation as the transmission source, the notification destination selection unit 236 selects a group corresponding to the context information of the notification source user.

In addition, the notification destination selection unit 236 does not need to perform the above-described group classification every time. For example, when the notification is made for the second time or later, the notification destination selection unit 236 is stored in the group storage unit 225 without performing group classification. A group may be selected.
Further, the notification destination selection unit 236 may generate, add, change, and delete group information stored in the group storage unit 225 in accordance with a change in the user situation. Here, the generation, addition, change, and deletion include generation, addition, change, and deletion of each group, and addition, change, and deletion of the target user.

  The notification processing unit 234 in the present embodiment has the same basic functions as in the first embodiment, but the processing related to the notification destination selection unit 236 is different. For example, the notification processing unit 234 transmits the notification information to the user terminal 10 corresponding to the notification destination user selected by the notification destination selection unit 236.

Next, the operation of the information notification system 1a according to the present embodiment will be described with reference to the drawings.
In addition, since the estimation process of a user's condition in this embodiment is the same as the process shown in FIG. 6 mentioned above, the description is abbreviate | omitted here. The processing for notifying another user of the user's situation when the predetermined notification condition in the present embodiment is satisfied and the process for checking the user's situation by designating the user are shown in FIGS. Therefore, the description thereof is omitted here.

FIG. 14 is a flowchart illustrating an example of a notification destination selection process according to a user situation in the present embodiment.
As shown in FIG. 14, in the information notification system 1a, when the notification destination is selected according to the user's situation, the notification destination selection unit 236 of the location information server 20a first stores the user corresponding to the designated situation as the user situation. A group is generated by selecting from the unit 224 (step S401). In other words, the notification destination selection unit 236 searches the user situation storage unit 224 and extracts users corresponding to the designated situation. Then, the notification destination selection unit 236 stores “group name” and “target user” in association with each other in the group storage unit 225 as illustrated in FIG. 13. The “group name” here is the name of the specified situation, and the “target user” is a list of user IDs of the extracted users.

  Next, the notification processing unit 234 transmits a message with the user classified into the group as a notification destination (step S402). For example, the notification processing unit 234 reads out a user corresponding to a group (specified situation) from the group storage unit 225 and sets it as a notification destination. The notification processing unit 234 transmits notification information such as a message to the notification destination user via the chat server 30. After the process of step S402, the notification processing unit 234 ends the process.

Next, an example of the operation of the information notification system 1a according to the present embodiment will be described with reference to FIG.
FIG. 15 is a diagram illustrating an example of the operation of the information notification system 1a according to the present embodiment.
The example illustrated in FIG. 15 illustrates an operation when the user A who owns the user terminal 10-1 notifies a message to all the users (user B, user C,...) In the conference room A. Here, the user terminal 10-2 is the user terminal 10 possessed by the user B, and the user terminal 10-3 is the user terminal 10 possessed by the user C.

The terminal control unit 14 of the user terminal 10-1 transmits the notification request to the location information server 20a via the NW communication unit 11.

  FIG. 16A shows an example of a menu screen of the user terminal 10-1 according to the present embodiment. In the menu screen G8 shown in FIG. 16A, when a button “send a message to a person in a specific area” is input from the selection button BT4 via the input unit 12, the user terminal 10-1 Displays a display screen G9 as shown in FIG. The user terminal 10-1 receives information such as “conference room A” in the input window W2 via the input unit 12.

  Next, the location information server 20a selects a notification destination (step S502). The notification destination selection unit 236 of the location information server 20a selects a user whose user status corresponds to “conference room A” from the user status storage unit 224, and displays group information (group information of the group GR1) in FIG. As shown, it is stored in the group storage unit 225.

  Next, the location information server 20a transmits a message to the selected notification destination (step S503). That is, the notification destination selection unit 236 reads the user corresponding to the selected “conference room A” from the group storage unit 225 as the notification destination, and transmits a message addressed to the notification destination to the chat server 30. The location information server 20a may confirm the user status of the selected group information and send a message to a user who may be notified. That is, the notification destination selection unit 236 reads the user corresponding to the selected “conference room A” as a notification destination candidate from the group storage unit 225, and then calls the situation estimation unit 233 to estimate the state of the notification destination user. For example, it is determined whether or not notification to the corresponding user is possible, for example, when the state of the user is “not in customer service.” The notification destination selection unit 236 uses the user who has determined that notification is possible as the notification destination and sets the notification destination as the notification destination. The destination message is transmitted to the chat server 30.

  Next, the chat server 30 transmits a message to the user B (step S504). The chat processing unit 32 of the chat server 30 transmits a message addressed to the user B to the user terminal 10-2 of the user B via the NW communication unit 31.

  Next, the user terminal 10-2 displays a message (step S505). For example, the terminal control unit 14 of the user terminal 10-2 displays a message from the user A on the display unit 13 as illustrated in the display screen G10 of FIG.

  The chat server 30 transmits a message to the user C (step S506). The chat processing unit 32 of the chat server 30 transmits a message addressed to the user C to the user terminal 10-3 of the user C via the NW communication unit 31.

Next, the user terminal 10-3 displays a message (step S507). For example, the terminal control unit 14 of the user terminal 10-3 displays a message from the user A on the display unit 13 as illustrated in the display screen G10 of FIG.
The chat server 30 also transmits a message to other users in the conference room A in the same manner.

In the example illustrated in FIG. 15 described above, the notification destination selection unit 236 has described an example in which a message is transmitted to all users in the conference room A. For example, messages, additional materials, questionnaires are sent to all seminar participants. For example, the notification destination selection unit 236 selects all seminar participants as notification destinations. In addition, for example, when it is designated as going out as the context information, the notification destination selection unit 236 selects all users who are out as the notification destination.
Further, in the example illustrated in FIG. 15 described above, the notification destination selection unit 236 selects the user at the same location as the notification source user (user A) as the notification destination. Alternatively, a user in a situation different from the situation of the notification source user may be selected as the notification destination.

As described above, the information notification system 1a according to the present embodiment includes the user terminal 10 associated with the user, the notification destination selection unit 236, and the notification processing unit 234. The notification destination selection unit 236 selects a notification destination user of the notification information based on the context information indicating the user status. The notification processing unit 234 transmits the notification information to the user terminal 10 corresponding to the notification destination user selected by the notification destination selection unit 236.
Thereby, the information notification system 1a according to the present embodiment can select a notification destination and notify a message without performing a complicated process in which the user manually selects the information notification destination one by one. Convenience can be improved.

Further, the information notification system 1a according to the present embodiment is based on the location information indicating the location of the user acquired by the user terminal 10, and includes at least location information indicating the location where the user is located and context information (user's status). A situation estimation unit 233 (an example of a context estimation unit). The notification destination selection unit 236 selects a notification destination user based on the context information estimated by the situation estimation unit 233.
As a result, the information notification system 1a according to the present embodiment selects the notification destination based on the estimated location information and the context information including the user state, so the user needs to input the context information (user status). There is no. Therefore, the information notification system 1a according to the present embodiment can further improve convenience.

Further, in the present embodiment, the notification destination selection unit 236 classifies users into groups related to the context information based on the context information (user status), and based on the context information specified by the notification source user. , A group is selected, and a user classified into the selected group is selected as a notification destination user.
Thereby, the information notification system 1a according to the present embodiment can appropriately select the notification source user by group. In addition, the information notification system 1a according to the present embodiment can select a group, and in the second and subsequent notifications, it is only necessary to select a group that has already been classified, and the processing can be simplified.

The information notification method according to the present embodiment includes a notification destination selection step and a notification processing step. In the notification destination selection step, the notification destination selection unit 236 selects a notification destination user of the notification information based on the context information indicating the user status. In the notification processing step, the notification processing unit 234 transmits notification information to the user terminal 10 corresponding to the notification destination user selected in the notification destination selection step.
Thereby, the information notification method according to the present embodiment has the same effect as the information notification system 1a described above, and can improve convenience.
