In addition, in each participant list information, in the distribution destination information, the e-mail address of the distribution destination used when simultaneously distributing the file to all users is set.

(Overview of information processing system processing)
FIG. 11 is a diagram for explaining an outline of processing by the information processing system 1 according to the first embodiment. FIG. 11 shows an example in which three users (Mary, Sato, Saito) hold a conference using the electronic blackboard device 14 in a conference room.

1. In order to use the electronic blackboard device 14 , each user needs to be logged in by the electronic blackboard device 14 by holding the IC card 630 over the RF tag reader 617 . Note that user login authentication may be performed by other methods (for example, a method of entering a user ID and password).

2. Participant list information is registered in the participant list for a user whose login has been authenticated by the electronic blackboard device 14, so that the electronic blackboard device 14 can recognize the user as a participant.

3. When each user is authenticated for login, he/she accesses his/her own storage in the storage service 44 (not limited to this, but may be a schedule service, a shared site service, etc.) from the electronic blackboard device 14. (reading of files and saving of files) becomes possible.

4. When the user leaves the conference room in which the electronic blackboard device 14 is installed, the login state automatically changes to the unauthenticated state. In this embodiment, the user automatically becomes unauthenticated after a certain period of time (for example, 3 minutes) has elapsed since the user was authenticated for login. The “authentication state” means a state (authentication ON) in which the user is logged in, registered in the participant list, and can use resources. "Unauthenticated state" means a state in which the user is logged in and registered in the participant list, but cannot use the resource (authentication is OFF). Also, the 'logout state' means a state in which the participant is not included in the participant list or is deleted after being included in the participant list, and the resource cannot be used.

5. When the user becomes unauthenticated, the electronic blackboard device 14 cannot access the user's storage. Therefore, it is possible to prevent other users from illegally accessing the storage of the user who has left the conference room.

6. After the meeting is over, the electronic blackboard device 14 sends the file showing the contents of the board writing displayed on the display 3 by e-mail (not limited to this, but may be file transmission to an external storage, a file server, etc.). can be sent to the e-mail addresses of all users (that is, including unauthenticated users) shown in the participant list.

However, the electronic blackboard device 14 does not distribute the file indicating the contents of the board writing to the user who has intentionally logged out. Further, the electronic blackboard device 14 may simultaneously distribute the file showing the contents of the board writing to other users (for example, users registered in the schedule) in addition to the user who has been logged in and authenticated.

As described above, in the information processing system 1 of the present embodiment, when the user leaves the conference room, the electronic blackboard device 14 cannot automatically access the user's storage. Therefore, according to the information processing system 1 of the present embodiment, it is possible to prevent a user other than the user who has left the conference room from illegally accessing the storage of the user who has left the conference room. .

(Procedure of processing by the electronic blackboard device 14)
12 and 13 are flowcharts showing the procedure of processing by the electronic blackboard device 14 according to the first embodiment.

In the electronic blackboard device 14, first, the user who logs in first holds the IC card 630 over the RF tag reader 617 (step S1201). At this time, the RF tag reader 617 reads identification information from the IC card 630 .

Next, the determination unit 56C of the participant management unit 56 starts monitoring the list of participants (step S1202). After that, the determination unit 56C calculates the elapsed time after login authentication for each user registered in the participant list at predetermined time intervals (for example, 1-second intervals). Then, if any of the users registered in the participant list has passed a predetermined time (for example, 3 minutes) after being authenticated for login, the determination unit 56C determines that the user has entered the electronic blackboard device 14 determined to have moved away from In this case, the determination unit 56C sets the authentication state of the participant list information of the user to "OFF".

Next, the participant management unit 56 transmits the identification information read in step S1201 to the user information server device 10, and acquires the service information of the user corresponding to the identification information from the user information server device 10 ( step S1203).

For example, if the identification information acquired from the IC card 630 is "ICCARD-123", the user ID "user001" corresponding to the identification information is specified from the user information list in FIG. Then, the participant management unit 56 acquires the service information "Service11" and "Service12" corresponding to the user ID "user001" from among the service information shown in FIG. FIG. 14 is a diagram showing an example of service information acquired by the participant management unit 56 according to the first embodiment.

Next, the registration unit 56B of the participant management unit 56 registers the participant list information of the user corresponding to the identification information read in step S1201 (user ID of the electronic whiteboard system, user name, authentication status, final authentication time, and distribution destination information) is registered in the list of participants (step S1204).

Next, the participant management unit 56 determines whether or not the user who logs in next has held the IC card 630 over the RF tag reader 617 (step S1205). If it is determined in step S1205 that ``the next user who logs in has held up the IC card 630'' (step S1205: Yes), the electronic blackboard device returns to step S1203, and the next user who logs in Acquire information and register participant list information.

On the other hand, if it is determined in step S1205 that "the next user who logs in does not hold the IC card 630" (step S1205: No), the electronic blackboard device 14 advances the process to step S1206.

In step S1206, the file reading unit 52 determines whether the file reading button has been pressed on any of the individual user information display screens 1300 (see FIG. 17) displayed for each user on the display 3 of the electronic blackboard device 14. to judge. If it is determined in step S1206 that "the file read button has not been pressed" (step S1206: No), the electronic blackboard device 14 proceeds to step S1212.

On the other hand, if it is determined in step S1206 that "the file read button has been pressed" (step S1206: Yes), the file reading unit 52 reads the participant list information of the user corresponding to the pressed file read button. By referring to the user list, it is determined whether or not the authentication status of the user is ON (step S1207).

In step S1207, if it is determined that “the authentication status is not ON” (step S1207: No), the file reading unit 52 displays an authentication error screen 1400 on the display 3 of the electronic blackboard device 14 via the blackboard display unit 58. (see FIG. 18) is displayed (step S1208), and predetermined re-authentication processing is executed (step S1209). Then, the electronic blackboard device 14 returns the process to step S1206.

The predetermined re-authentication process is, for example, displaying a screen prompting to re-execute login authentication on the display 3, or re-executing login authentication when the user holds the IC card 630 over the RF tag reader 617 again. It is a process that In this re-authentication process, if the user is logged-in authenticated again, the authentication status in the participant list information of the user is set to "ON" again. In the example shown in FIG. 12, the process is returned to step S1206 after this re-authentication process, but the process is not limited to this. For example, in this re-authentication process, if the user is logged-in authenticated again, the file reading unit 52 may proceed to step S1210 to display the file selection screen on the display 3 .

On the other hand, if it is determined in step S1207 that the "authentication state is ON" (step S1207: Yes), the file reading unit 52 displays the file selection screen 1100 illustrated in FIG. , is displayed on the display 3 of the electronic blackboard device 14 (step S1210).

FIG. 15 is a diagram showing an example of a file selection screen displayed on the display 3 of the electronic blackboard device 14 according to the first embodiment.

FIG. 21 is a functional configuration diagram of an example of an information processing system according to the second embodiment. The information processing system 1 according to the second embodiment differs from the information processing system 1 according to the first embodiment in that an electronic blackboard device 14</b>A is provided instead of the electronic blackboard device 14 . The electronic blackboard device 14A differs from the electronic blackboard device 14 in that a face tracking unit 66 is further provided.

The face tracking unit 66 tracks the faces of all users registered in the participant list with respect to images captured by the camera 618 (see FIG. 3). For example, the face tracking unit 66 tracks each user's face based on feature point information (see FIG. 22) representing the feature points of each user's face using a known image recognition technique. It is assumed that the camera 618 captures an image in front of the electronic blackboard device 14A. Thereby, the camera 618 can capture an image including the face of each user present in the installation location (for example, conference room) of the electronic blackboard device 14A.

In the second embodiment, the predetermined condition determined by the determination unit 56C of the participant management unit 56 is that one of the users registered in the participant list is no longer appearing in the image captured by the camera 618. be.

For example, the face tracking unit 66 checks at predetermined time intervals (for example, every 30 seconds) whether or not each user registered in the participant list appears in the image captured by the camera 618. . Then, for example, the face tracking unit 66 detects that one of the users registered in the participant list has not appeared in the images captured by the camera 618 for a predetermined number of times (for example, five times) in succession. If confirmed, the determination unit 56C determines that the user has moved away from the electronic blackboard device 14A.

Then, as in the first embodiment, the restriction unit 56D of the participant management unit 56 sets the user determined by the determination unit 56C to have moved away from the electronic blackboard device 14A to an unauthenticated state, and the resources owned by the user ( Restrict access to files and folders in storage service 44).

For example, the face tracking unit 66 causes the camera 618 to capture an image of the user's face when the user holds the IC card 630 over the IC card 630 . Then, the face tracking unit 66 extracts the feature points of the user from the image of the user's face, associates the feature point data of the user with the user ID of the user, and stores the feature point information list (see FIG. 22). register. That is, the face tracking unit 66 registers the user's feature point data in the feature point information list each time the user holds the IC card 630 over the IC card 630 . However, not limited to this, feature point data of each user may be associated with a user ID in advance and stored in the electronic blackboard device 14A, the user information server device 10, or the like.

Next, the face tracking unit 66 determines whether or not there is a user not appearing in the image captured by the camera 618 (step S2403). If it is determined in step S2403 that "there is no user not shown in the image" (step S2403: No), the electronic blackboard device 14A advances the process to step S2408.

On the other hand, if it is determined in step S2403 that "there is a user who is not shown in the image" (step S2403: Yes), the face tracking unit 66 detects that the number of times the user is not shown in the image is five consecutive times. It is determined whether or not there is (step S2404).

If it is determined in step S2404 that "the number of times the user is not shown in the image is not five consecutive times" (step S2404: No), the electronic blackboard device 14A advances the process to step S2408.

On the other hand, if it is determined in step S2404 that "the number of times the user is not shown in the image is five consecutive times" (step S2404: Yes), the decision unit 56C of the participant management unit 56 It is determined that the user has left (that is, moved away from the electronic blackboard device 14A) (step S2405). Then, the restriction unit 56D of the participant management unit 56 sets "OFF" to the authentication status in the participant list information of the user determined to have left (step S2406).

Thereafter, the face tracking unit 66 excludes the user determined to have left from the tracking target, and the electronic blackboard device 14A advances the process to step S2408.

[Third embodiment]
Next, a third embodiment will be described. In this third embodiment, changes from the first embodiment will be described. In addition, in this 3rd Embodiment, about the structure part similar to 1st Embodiment, the same code|symbol as 1st Embodiment is attached|subjected, and detailed description is abbreviate|omitted.

(System configuration)
FIG. 26 is a configuration diagram of an example of an information processing system according to the third embodiment. The information processing system 1 shown in FIG. 26 further includes a device management server 11 and a PC 18, and also includes an electronic blackboard device 14B instead of the electronic blackboard device 14. The information processing system 1 of the first embodiment (FIG. 1). The device management server 11 and the PC 18 are connected to the network 16 and can communicate with the electronic blackboard device 14B via the network 16. FIG.

The device management server 11 stores device management information, which will be described later, and the like, and is used by the electronic blackboard device 14B. The equipment management server 11 is realized by one or more computers. Although the configuration diagram of FIG. 1 shows an example in which the user information server device 10 and the device management server 11 are separate, the user information server device 10 and the device management server 11 may be realized by one server device. good.

The PC 18 is an example of a “terminal device” and can be remotely connected to the electronic blackboard device 14B via the network 16 . A user can remotely participate in a conference using the electronic blackboard device 14B by remotely connecting to the electronic blackboard device 14B from the PC 18 .

(Overview of information processing system processing)
FIG. 27 is a diagram for explaining an outline of processing by the information processing system 1 according to the third embodiment. FIG. 27 shows an example in which three users (Mary, Sato, Saito) hold a meeting in a meeting room using the electronic blackboard device 14B.

1. In order to use the electronic blackboard device 14B, each user needs to be logged in by the electronic blackboard device 14B by holding the IC card 630 over the RF tag reader 617 . Note that user login authentication may be performed by other methods (for example, a method of entering a user ID and password).

2. Participant list information is registered in the participant list for a user who has been logged in by the electronic blackboard device 14B, so that the user can be recognized as a participant by the electronic blackboard device 14B.

3. When each user is authenticated for login, he/she accesses his/her own storage in the storage service 44 (not limited to this, and may be a schedule service, a shared site service, etc.) from the electronic whiteboard device 14B. (reading of files and saving of files) becomes possible.

4. When the user leaves the conference room in which the electronic blackboard device 14B is installed, the login state automatically changes to the unauthenticated state. In this embodiment, the user automatically becomes unauthenticated after a certain period of time (for example, 3 minutes) has elapsed since the user was authenticated for login. The “authentication state” means a state (authentication ON) in which the user is logged in, registered in the participant list, and can use resources. "Unauthenticated state" means a state in which the user is logged in and registered in the participant list, but cannot use the resource (authentication is OFF). Also, the 'logout state' means a state in which the participant is not included in the participant list or is deleted after being included in the participant list, and the resource cannot be used.

5. When the user becomes unauthenticated, the user's storage cannot be accessed from the electronic blackboard device 14B. Therefore, it is possible to prevent other users from illegally accessing the storage of the user who has left the conference room. FIG. 27 shows an example in which user "Mary" automatically becomes unauthenticated when user "Mary" leaves the conference room, and thus cannot access user "Mary"'s personal storage.

6. A user who has left the conference room can remotely participate in a video conference or remote sharing of the conference by remotely connecting to the electronic blackboard device 14B from an external terminal device. FIG. 27 shows an example in which the user "Mary" who has left the conference room remotely connects to the electronic blackboard device 14B from the PC 18 in the room. At this time, in the PC 18, based on the user ID of the logged-in user "Mary", the device (that is, the electronic blackboard device 14B in FIG. 27) in which the conference in which the user "Mary" is a participant is Presented as a possible remote destination. As a result, the user "Mary" can easily establish a remote connection from the PC 18 to the electronic blackboard device 14B.

7. After the meeting ends, the electronic blackboard device 14B sends the file showing the contents of the board-written content displayed on the display 3 by e-mail (not limited to this, but may be file transmission to an external storage, a file server, etc.). can be broadcast to the e-mail addresses of all users (that is, both authenticated and unauthenticated users) shown in the participant list.

However, the electronic blackboard device 14B does not distribute the file indicating the contents of the blackboard writing to the user who has intentionally logged out.

Note that the remote connection unit 70 of the PC 18 can remotely operate the screen 3800 . That is, the remote connection unit 70 of the PC 18 can perform remote operations (for example, writing, selection, file display, etc.) on the screen 3800 displayed on the electronic blackboard device 14B. In this case also, the display contents of the screen 3800 are similarly changed in the PC 18 as well.

In FIG. 38, since "Mary" has left the conference room, "Mary" is "unauthenticated" on the screen 3800 of the electronic blackboard device 14B in the conference room. Also, the screen 3800 is remotely shared on the screen of the PC 18 . Therefore, while the electronic blackboard device 14B restricts access to the storage of "Mary" by the participants in the meeting room, the information shared at the meeting such as writing on the blackboard is transferred from the electronic blackboard device 14B to the ID of "Mary". You can send emails and files to the linked destination. Note that "Mary" is in the "authenticated state" on the PC 18 side with the remote connection application, and from the screen of the remote connection application, "Mary" can view and write files in her personal storage, and remotely access screens and files to the electronic blackboard device 14B.
