[Figure 7] 4 is a flowchart showing the operation of the telework avatar device 10 of one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

[0027] FIG. 1 is a diagram showing the system configuration of a communication system according to an embodiment of the present invention.

[0028] As shown in FIG. 1, the communication system of one embodiment of the present invention is configured such that a terminal device 60 of a telework user working from home and a telework avatar device 10 used in the office are interconnected via a wireless LAN terminal 70, the Internet 50, a router 30, an in-house network, and a wireless LAN terminal 40.

[0029] Here, the telework avatar device 10 is a robot that expresses information about a telework user who is working at a place away from the office, such as at home, through light, facial expressions, etc. By installing such a telework avatar device 10 in the office instead of the telework user, it becomes possible for the telework user to participate in meetings and discussions on behalf of the user and to converse with other users in the office.

[0030] In addition, when a telework user is working from home, for example, the light on the telework avatar device 10 can be turned on in green, allowing surrounding users in the office to know that the telework user is working from home.

[0031] In other words, the telework avatar device 10 functions as an avatar, or avatar, of a telework user in a remote location, thereby realizing communication with other users in the office.

[0032] A schedule management server 20 for managing schedule information of users in the office, including telework users, is connected to the intranet within the office.

[0033] The external configuration of this telework avatar device 10 is shown in Fig. 2. As shown in Fig. 2, the telework avatar device 10 has an external appearance of a sphere resembling a human face placed on a box-shaped base housing a power source such as a battery. The telework avatar device 10 also includes a camera 16 for capturing images of the surroundings and a speaker 18 for audio output.

[0034] An example of how this telework avatar device 10 is used in an office will be described with reference to Fig. 3. For example, in Fig. 3, telework avatar device 10A is connected to a terminal device of user A, and telework avatar device 10B is connected to a terminal device of user B.

[0035] Other users who are actually working in the office can hold meetings or conferences with telework users who are working at home via telework avatar device 10A and telework avatar device 10B.

[0036] However, if such a telework avatar device 10 is constantly connected to the terminal device 60 of a telework user working from home, the everyday sounds of the teleworker, his / her monologue, and sounds that give an insight into the situation at home will reach the telework avatar device 10 in the office.

[0037] In addition, the telework avatar device is connected to the Internet 50 by wireless communication using a Wi-Fi (registered trademark) line, and has an internal power source such as a battery, making it mobile. Therefore, when a conference including a telework user as a participant is held in a separate conference room, if another user participating in the conference takes the telework avatar device 10 to the conference room, the conference can be held with the telework user participating.

[0038] In such a case, a user who is trying to move the telework avatar device 10 may leave the telework avatar device 10 somewhere along the way, or may leave the telework avatar device 10 at a location where the user of the telework avatar device 10 should not participate in. There may also be a case where the user of the telework avatar device 10 leaves the telework avatar device 10 in a conference room after the end of a conference in which the user participated.

[0039] In such a case, audio information or image information that should not be sent to the telework user ends up being sent to the terminal device 60 of the telework user.

[0040] In this way, if the telework avatar device 10 is kept constantly powered on and constantly connected to the telework user's terminal device 60, and surrounding audio and images are constantly transmitted to the teleworker's terminal device 60, unnecessary information that should not be transmitted will be transmitted.

[0041] In order to solve such problems, it is conceivable that such a telework avatar device 10 could be equipped with a switch for stopping audio transmission or image capture, so that when audio or image information should not be transmitted, the switch can be operated to stop audio transmission or image capture.

[0042] However, when the number of such telework avatar devices 10 increases, the effort of operating the switches of each telework avatar device 10 becomes cumbersome, and users may forget to turn the switches on or off. In particular, when different users are to participate in each conference, each time a different conference is held, it is necessary to identify the participants in that conference and turn the switches of the telework avatar devices 10 on and off, which is troublesome work.

[0043] Therefore, in the present embodiment, the telework avatar device 10 performs the control described below to prevent unnecessary information that should not be sent from being sent when sending and receiving information such as voice and images between telework users in remote locations.

[0044] Next, the hardware configuration of the telework avatar device 10 in the image forming system of this embodiment is shown in FIG.

[0045] 4, the telework avatar device 10 has a CPU 11, memory 12, a storage device 13 such as a hard disk drive, a communication interface (abbreviated as IF) 14 for transmitting and receiving data to and from external devices via a network, a user interface (abbreviated as UI) device 15 for informing surrounding users of the status of the telework user, a camera 16, a microphone 17, a speaker 18, and a human presence sensor 19. These components are connected to each other via a control bus.

[0046] CPU 11 is a processor that executes a predetermined process based on a control program stored in memory 12 or storage device 13, and controls the operation of telework avatar device 10. Note that, in this embodiment, CPU 11 is described as reading and executing a control program stored in memory 12 or storage device 13, but it is also possible to provide the program to CPU 11 by storing it on a storage medium such as a CD-ROM.

[0047] FIG. 5 is a block diagram showing the functional configuration of the telework avatar device 10 that is realized by executing the above control program.

[0048] As shown in FIG. 5, the telework avatar device 10 of this embodiment includes a facial expression control unit 31, a lighting unit 32, a data memory unit 33, a wireless communication unit 34, a control unit 35, a camera 16, a microphone 17, a speaker 18, and a human presence sensor 19.

[0049] The facial expression control unit 31 controls the facial expression of the part that imitates a human face in the telework avatar device 10. Based on the control by the control unit 35, the lighting unit 32 lights up in a preset lighting color according to the state of the telework user, such as whether the telework user is working from home.

[0050] The data storage unit 33 stores various data used when the control unit 35 performs control.

[0051] The wireless communication unit 34 transmits and receives data to and from the wireless LAN terminal 40 via a short-distance wireless communication line such as Wi-Fi (registered trademark).

[0052] The camera 16 functions as an image capturing unit that captures an image of the surroundings. The microphone 17 functions as a sound capturing unit that captures sound information of the surroundings. The speaker 18 functions as a sound output unit that outputs a sound signal transmitted from the terminal device 60.

[0053] The control unit 35 controls the operation of the entire telework avatar device 10, and transmits images captured by the camera 16 and audio signals acquired by the microphone 17 via the Internet 50 to the terminal device 60 of the telework user working from home, and controls the audio signals transmitted from the terminal device 60 to be output from the speaker 18.

[0054] The human presence sensor 19 is a human presence detection means for detecting whether or not there is at least one human being in the vicinity, using infrared rays or the like.

[0055] When the control unit 35 acquires and transmits various types of information such as surrounding audio information and image information to the terminal device 60 of a telework user in a remote location, if the current time in the telework user's schedule is not included in a time period in which the telework user has plans to have a conversation with another user, the control unit 35 performs control to stop at least some of the functions of the camera 16, microphone 17, etc. that transmit information to the terminal device 60 of the telework user.

[0056] Here, a plan for having a conversation with another user means a plan that requires communication through conversation with another user, such as a conference, a meeting, or the like.

[0057] The control unit 35 accesses the schedule management server 20 via the in-house network to acquire schedule information of the telework user, and grasps the schedule of the telework user based on the acquired schedule information.

[0058] An example of the schedule information thus acquired by the control unit 35 from the schedule management server 20 is shown in FIG.

[0059] By referring to the schedule information shown in Figure 6, it is possible to see the time periods when various conferences, arrangements, meetings, etc. are scheduled, and by comparing the current time with this schedule information, it is possible to determine whether the user is currently in a conference, etc.

[0060] In addition, when the current time in the telework user's schedule is included in a time period in which a conversation is scheduled to take place between the telework user and another user, the control unit 35 performs control to enable the function of transmitting information to the terminal device 60 of the telework user.

[0061] Furthermore, even if the current time in the telework user's schedule is included in a time period in which the telework user is scheduled to have a conversation with another user, if the human presence sensor 19 does not detect the presence of a user in the vicinity, the control unit 35 performs control to stop at least part of the function of transmitting information to the telework user's terminal device 60.

[0062] In other words, if the telework avatar device 10 is left behind in a toilet or sink while moving to a conference room or the like, even though there is no one nearby, if the audio information captures an image and transmits it to the terminal device 60 of a telework user in a remote location, unnecessary information will be transmitted.

[0063] In other words, in the case of a meeting or conference, it is assumed that there are other users around the telework avatar device 10, so there is no problem in acquiring and sending audio information or image information. However, if audio information or image information is acquired and sent when there is no one around, it may result in the transmission of information that should not be sent.

[0064] In addition, the control unit 35 may acquire location information from the terminal device 60 of the telework user, and if the location of the terminal device 60 is not within a predetermined range, perform control to stop at least a portion of the function of transmitting information to the terminal device 60 of the telework user.

[0065] For example, if a telework user takes the terminal device 60 out of the home and sends information in the office to the terminal device 60, the information in the office may be leaked to a third party. If the telework user leaves the terminal device 60 behind when going out, the possibility of the information in the office being leaked to a third party increases. Therefore, in order to prevent such a situation from occurring, the home of the telework user is registered as a preset range, which prevents the terminal device 60 from sending information to a location other than the home of the telework user.

[0066] Furthermore, the control unit 35 may be configured to perform control to stop at least a portion of the function of transmitting information to the terminal device 60 when the presence of a telework user is not detected around the terminal device 60 of the telework user.

[0067] In other words, if the presence of a telework user is not detected around the terminal device 60, it means that the telework user is away from the terminal device 60 and is not ready to hold a conference, etc. In such a case, sending audio information or image information to the terminal device 60 is meaningless, and there is also a possibility that unnecessary information may be leaked to other third parties.

[0068] In addition, if no device such as earphones or headphones is connected to the external audio output terminal of the telework user's terminal device 60, the control unit 35 may perform control to stop at least a portion of the function of transmitting audio information and image information to the telework user's terminal device 60.

[0069] Here, the control of switching whether or not to transmit information depending on the presence or absence of a device such as an earphone or a headphone may be performed only when the telework user is in a specific location. In other words, when the telework user is at home, even if a device such as an earphone is not connected and audio is output from a speaker, there is a low possibility that information will be leaked to other third parties. Therefore, even if a device such as an earphone is not connected to an external audio output terminal, audio information, etc. may be transmitted to the terminal device 60. Conversely, when the telework user is in a location other than the home, audio information, etc. is not transmitted to the terminal device 60 because there is a possibility that information will be leaked to third parties in the vicinity if audio is output from a speaker.

[0070] Here, in this embodiment, the functions for transmitting information to the terminal device 60 of the telework user have been described using a function for transmitting image information captured by a camera and a function for transmitting surrounding audio information acquired by a microphone, but it is also possible to control whether or not information other than such audio information and image information is transmitted to the terminal device 60.

[0071] Next, the operation of the telework avatar device 10 of this embodiment will be described in detail with reference to the drawings.

[0072] FIG. 7 is a flowchart for explaining the operation of the telework avatar device 10 of this embodiment.

[0073] Here, the telework avatar device 10 will be described as being constantly powered on and constantly connected to the terminal device 60 of the telework user.

[0074] In this state, in step S101, the control unit 35 determines, based on the schedule information acquired from the schedule management server 20, whether the current time has reached the start time of a meeting or the like in the schedule of the telework user.

[0075] Then, when the current time period becomes a time period for a meeting or the like in the schedule information, the control unit 35 activates the human sensor 19 in step S102 to detect the presence of surrounding users.

[0076] Then, in step S103, if the presence of a nearby user is detected by the human presence sensor 19, the control unit 35 acquires the location information of the terminal device 60 of the telework user in step S104.

[0077] Here, in step S105, if the acquired location information of the terminal device 60 is a previously set and approved location, for example, the home of the telework user, the control unit 35 determines in step S106 whether the telework user is ready for use.

[0078] Specifically, the control unit 35 may activate the camera of the terminal device 60 and determine whether the telework user is ready for the meeting based on whether the face of the telework user can be detected, or may determine whether the telework user is ready for the meeting based on whether earphones or the like as described above are connected to the external audio output terminal of the terminal device 60.

[0079] Then, in step S106, if it is determined that the telework user is ready for the conference, the control unit 35 turns on the functions of the camera 16 and the microphone 17 in step S107.

[0080] Then, in step S108, the control unit 35 transmits and receives audio information to and from the terminal device 60 and transmits images captured by the camera 16 to the terminal device 60, thereby carrying out the video conference.

[0081] If the current time passes the end time of the conference in the schedule, the control unit 35 determines in step S109 that the video conference has ended.

[0082] Then, in step S110, the control unit 35 turns off the functions of the camera 16 and the microphone 17.

[0083] Then, the control unit 35 proceeds to the process of step S101 and enters a standby state until the start time of the next meeting, etc. Note that in any of the following cases: no surrounding users are detected in step S103, the location information acquired in step S105 is not the home of the telework user, and it is determined in step S106 that the telework user is not ready, the control unit 35 proceeds to the process of step S101 and enters a standby state until the start time of the next meeting, etc.

[0084] In each of the above embodiments, the term "processor" refers to a processor in a broad sense, including general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0085] In addition, the operations of the processor in each of the above embodiments may be performed not only by one processor, but also by multiple processors located at physically separate locations working together. Furthermore, the order of the operations of the processor is not limited to the order described in each of the above embodiments, and may be changed as appropriate.

[0086] [Variations] In the above embodiment, a case has been described in which the telework avatar device 10 is set up in an office and connected to the terminal device 60 of a telework user, but the present invention is not limited to this, and the present invention can be similarly applied to cases in which various information processing devices such as smartphones, laptops, tablet terminal devices, etc. are connected to the terminal device 60 of a telework user instead of the telework avatar device 10.
